BACKGROUND

[0001] Computing devices, such as smartphones, laptops, and tablets, may include a display for outputting content such as user interfaces, text, photos, videos, and the like. While conventional displays for computing devices have typically been rigid surfaces made of rigid materials, such as glass, that cannot be folded or otherwise bent, flexible displays made of flexible materials, such as plastic, that can be bent or folded have been recently developed that enable manufacturers and designers of mobile computing devices to reimagine the form factors of computing devices. Such computing devices with reimagined form factors may include, for example, clamshell or foldable computing devices in which two or more sections of the computing device can be flipped open and closed.

SUMMARY

[0002] In general, this disclosure describes a computing device having support plates for supporting a flexible display in the computing device. A flexible display, such as a flexible organic light-emitting diode display, may be made up of multiple layers of material, such as plastic film. For example, a flexible display may include one or more cathode layers, a conductive layer, an emissive layer, an anode layer, and a flexible substrate.

[0003] Due to the flexibility of the flexible display, the computing device may include support plates that meet the flexible display and provide support to the flexible display when the flexible display of a computing device is unfolded, such as when the flexible display is laid flat. However, when the flexible display is folded (e.g., in half), internal stress in the bending area of the flexible display cause the bending area of the flexible display to bulge outwards compared with areas of the flexible display that are not bent. As such, if the support plates do not leave sufficient space for the outward bulging of the bending area of the flexible display when the flexible display is bent, the support plates may cause additional stress by pressing against the flexible display.

[0004] In accordance with aspects of the present disclosure, to prevent introducing additional stress to the flexible display when the flexible display is folded, the computing device may utilize a water drop-type hinge mechanism that moves support plates in the computing device towards the flexible display as the flexible display is unfolded to provide support to the flexible display when the flexible display of a computing device is unfolded, and that moves the support plates away from the flexible display as the flexile display is folded, thereby creating a gap between the flexible display and the support plates when the flexible display is folded for the outward bulging of the bending area of the flexible display when the flexible display is folded. To that end, while a support plate may rotate according to a first joint at a first end of the support plate, the computing device may include a slide module that guides the linear movement of an opposing end of the support plate, such that the support plate moves towards the flexible display as the flexible display is unfolded, and moves away from the flexible display as the flexible display is folded, thereby creating a gap between the flexible display and the support plate when the flexible display is folded. In this way, the computing device prevents the introduction of additional stress to the flexible display when folded, thereby increasing the reliability and operational longevity of the flexible display.

[0005] In one example, a computing device includes a housing. The computing device further includes a flexible display operable to be folded to a first position and unfolded to a second position, wherein the flexible display is coupled to the housing. The computing device further includes a support plate for supporting at least a portion of the flexible display when the flexible display is unfolded to at least the second position, the support plate being disposed within the housing between at least a portion of the flexible display and a portion of the housing, the support plate having a first joint coupled to a first end of the support plate and a second joint coupled to a second end of the support plate distal from the first end of the support plate, and the support plate being pivotable about the first joint as the flexible display is folded and unfolded between the first position and the second position. The computing device further includes a slide module in the housing having a fixed position in relation to the housing, the slide module having a slot that accepts the second joint and guides a linear slide movement of the second joint along a linear path of movement within the slot as the support plate pivots about the first joint, wherein the support plate moves according to the first joint and the second joint to support at least the portion of the flexible display when the flexible display is unfolded to the second position and moves according to the first joint and the second joint to create a gap between at least a portion of the support plate and at least the portion of the flexible display when the flexible display is folded to the first position. [0006] In another example, a computing device includes a flexible display operable to be folded and unfolded, wherein the flexible display is folded when the computing device is in a closed position and fully unfolded when the computing device is in an open position. The computing device further includes a first housing coupled to the flexible display, wherein the first housing pivots about a first joint coupled to the first housing. The computing device further includes a second housing coupled to the flexible display, wherein the second housing pivots about a second joint coupled to the second housing. The computing device further includes a slide module coupled to the first housing, the slide module having a slot. The computing device further includes a support plate disposed between a portion of the first housing and a portion of the flexible display, wherein the support plate is coupled to a third joint at a first end of the support plate and to a fourth joint coupled to a second end of the support plate distal to the first end of the support plate, wherein the support plate rotates about the third joint, and wherein at least a portion of the fourth joint is disposed in the slot of the slide module, wherein the slot of the slide module define a linear path of movement for the fourth joint such that when the support plate rotates about the third joint, the fourth joint moves according to the linear path of movement, such that when the first housing and the second housing rotatably moves away from each other, the movement of the fourth joint according to the linear path of movement causes a portion of the support plate to moves towards the flexible display and to meet the flexible display when the computing device is in the open position, and when the first housing and the second housing rotatably moves towards each other, the movement of the fourth joint according to the linear path of movement causes the portion of the support plate to move away from the flexible display and to leave a gap between the portion of the support plate and the flexible display when the computing device is in the closed position.

DETAILED DESCRIPTION

[0015] FIGS. 1A-1C are conceptual diagrams illustrating a cross-sectional profile view of an example computing device having a flexible display, in accordance with one or more aspects of this disclosure. As shown in FIGS. 1A-1C, computing device 100 includes flexible display 102, such as a flexible organic light-emitting diode display or any other suitable flexible display.

[0016] Computing device 100 may include housing 110A-110C that forms at least a portion of the exterior of computing device 100. Housing HOA may include top portion 124A and side portion 122A while housing HOB may include top portion 124B and side portion 122B. When computing device 100 is in a closed position, as shown in FIG. 1 A, top portion 124 A and top portion 124B may define at least a portion of a top external end of computing device 100 that is opposite housing HOC that may define at least a portion of a bottom external end of computing device 100, while side portion 122 A of housing 110A and side portion of 122B of housing HOB may each define at least a portion of an exterior side of computing device 100, where side portion 122 A and side portion 122B may define opposite external sides of computing device 100.

[0017] Computing device 100 may include joint module 115 which accepts joints 106A and 106B and joints 112A and 112B. Housing HOA may be coupled to joint 112A and housing 110B may be coupled to joint 112B so that housing HOA may pivot about joint 112A and housing HOB may pivot about joint 112B. When computing device 100 is in a closed position, as shown in FIG. 1A, housing HOA and housing HOB are disposed substantially parallel to each other, and housing HOAmay pivot about joint 112Ato rotate away from housing HOB, such as according to path 120 A, and housing HOB may pivot about joint 112B to rotate away from housing 110A, such as according to path 120B.

[0018] Computing device 100 may include support plates 104A and 104B to provide support for flexible display 102. Support plate 104A may be housed in housing 110A and support plate 104B may be housed in housing HOB. In some examples, when computing device 100 is in a closed position, such as shown in FIG. 1A, support plate 104A may be substantially parallel with respect to side portion 122A of housing HOA and support plate 104B may be substantially parallel with respect to side portion 122B of housing HOB, and support plate 104A and support plate 104B may be substantially parallel with respect to each other.

[0019] Support plate 104Amay be coupled to joint 106A via connector 126A at end 103 A of support plate 104 A, and support plate 104B may be coupled to joint 106B via connector 126B at end 103B of support plate 104B, so that support plate 104A may pivot about joint 106 A and support plate 104B may pivot about joint 106B to rotatably move towards and away from flexible display 102. When computing device 100 is in a closed position, as shown in FIG. 1A, support plate 104A may pivot about joint 106Ato rotate away from support plate 104B, and support plate 104B may pivot about joint 106B to rotate away from support plate 104 A.

[0020] Joint module 115 may include or otherwise accept joints 112A and 112B and joints 106A and 106B. That is, in some examples, joints 112A and 112B and/or joints 106 A and 106B may be pins or other components coupled to or accepted by joint module 115 to connect to housing 110 A, housing 110B, support plate 104 A, and support plate [0021] When computing device 100 is in a closed position, as shown in FIG. 1A, flexible display 102 may be folded at point 132 into two substantially similar halves, and flexible display 102 forms a waterdrop shape, where folded portion 102B of flexible display 102 bulges outwards compared with edge portion 102A of flexible display 102. Flexible display 102 has an exterior surface 130A and an interior surface 130B, where the interior surface 130B may face support plates 104 A and 104B while portions of exterior surface 130A may face each other.

[0022] Support plates 104A and 104B may provide support for flexible display 102 when flexible display 102 is in a fully unfolded position, such as shown in FIG. 1C, such that support plates 104 A and 104B may each meet at least a portion of interior surface 130B of flexible display 102 to provide support for flexible display 102. However, when flexible display 102 is folded to a closed position, such as shown in FIG. 1A, portions of interior surface 130 of flexible display 102, such as the portions of interior surface 130 of flexible display 102 in folded portion 102B of flexible display 102, may bulge out towards support plates 104A and 104B.

[0023] As such, when flexible display 102 is folded to a closed position, support plates 104A and 104B are disposed within housing HOA and HOB, respectively, such that there is a gap 114A between a surface of at least a portion of support plate 104Athat faces flexible display 102 and at least a portion of interior surface 130B of flexible display 102 that faces housing 110A, and a gap 114B between a surface of at least a portion of support plate 104B that faces flexible display 102 and at least a portion of interior surface 130B of flexible display 102 that faces housing HOB.

[0024] To guide the movement of support plates 104A and 104B so that there is a gap 114A between at least a portion of support plate 104 A and at least a portion of interior surface 130B of flexible display 102 that faces housing 110A and that there is a gap 114B between at least a portion of support plate 104B and at least a portion of interior surface 130B of flexible display 102 that faces housing HOB when computing device 100 is in a closed position, such as shown in FIG 1A, housing 110A and HOB may include slide module 116A and slide module 116B, respectively for guiding the movement of support plates 104 A and 104B, respectively.

[0025] Slide modules 116A and 116B may each have a fixed position with respect to housing HOA and housing HOB, respectively. That is, the position of slide module 116A is fixed in relation to housing 110A regardless the rotation of housing 110A about joint 112A, and the position of slide module 116B is fixed in relation to housing HOB regardless the rotation of housing HOB about joint 112B. In some examples, slide module 116A may be attached or otherwise coupled to housing HOAin the interior of housing 110A and slide module 116B may be attached or otherwise coupled to housing HOB in the interior of housing HOB.

[0026] Support plate 104 A may be coupled to joint 108 A, such as a pin, via connector 118A at end 105A of support plate 104A distal to end 103A and support plate 104B may be coupled to joint 108B, such as a pin, via connector 118B at end 105 A of support plate 104A distal to end 103B. In some examples, support plate 104A may be directly coupled to joint 108 A without connector 118A, such as when connector 118Ais a part of support plate 104 A, and support plate 104B may be directly coupled to joint 108B without connector 118B, such as when connector 118B is a part of support plate 104B.

[0027] Slide module 116A may include slot 111 A that accepts at least a portion of joint 108 A and that guides a slide movement of joint 108 A along a linear direction within slot ll lA as support plate 104A pivots about joint 106A. That is, slot ll lAmay define a linear path of movement 117A for joint 108 A as support plate 104 A pivots about joint 106 A, thereby guiding the movement of at least a portion of support plate 104 A towards and away from flexible display 102 as support plate 104A pivots about joint 106A.

[0028] Similarly, slide module 116B may include slot 11 IB that accepts at least a portion of joint 108B and that guides a slide movement of joint 108B along a linear direction within slot 11 IB as support plate 104B pivots about joint 106B. That is, slot 11 IB may define a linear path of movement 117B for joint 108B as support plate 104B pivots about joint 106B, thereby guiding the movement of at least a portion of support plate 104B towards and away from flexible display 102 as support plate 104B pivots about joint 106B.

[0029] For example, slot 111 A may guide the linear movement of joint 108 A along linear path of movement 117Ato cause at least a portion of support plate 104 A coupled to joint 108Ato move towards interior surface 130B of flexible display 102 as housing 110A pivots about joint 112A away from housing HOB, such as according to path 120A, and may guide the linear movement of j oint 108 A along linear path of movement 117 A to cause at least a portion of support plate 104 A coupled to joint 108 A to move away from interior surface 130B of flexible display 102 as housing 110A pivots about joint 112A back towards housing HOB.

[0030] Similarly, slot 11 IB may guide the linear movement of joint 108B along linear path of movement 117B to cause at least a portion of support plate 104B coupled to joint 108B to move towards interior surface 130B of flexible display 102 as housing HOB pivots about joint 112B away from housing 110A, such as according to path 120B, and may guide the linear movement of joint 108B along linear path of movement 117B to cause at least a portion of support plate 104B coupled to joint 108B to move away from interior surface 130B of flexible display 102 as housing HOB pivots about joint 112B back towards housing 110A.

[0031] When computing device 100 is in a closed position, such as shown in FIG. 1A, joint 108A is positioned in slot 111 A such that such that there is a gap 114A between a surface of at least a portion of support plate 104Athat faces flexible display 102 and at least a portion of interior surface I 30B of flexible display 102 that faces housing 110A. When housing 110A pivots about joint 112Ato rotatable move away from housing HOB, such as according to path 120 A, so that computing device 100 transitions from a closed position to a partially open position, such as shown in FIG. IB, slot 111 A guides the linear movement of joint 108 A along linear path of movement 117A away from side portion 122A of housing 110A. Becausejoint 108A is coupled to end 105A of support plate 104 A, the linear movement of joint 108 A along linear path of movement 117A away from side portion 122 A of housing 110A causes at least a portion of support plate 104 A near end 105Ato move towards at least a portion of interior surface I 30B of flexible display 102 that faces housing 110A, thereby decreasing gap 114Abetween a surface of at least a portion of support plate 104Athat faces flexible display 102 and at least a portion of interior surface I 30B of flexible display 102 that faces housing 110A.

[0032] From the partially open position shown in FIG. IB, housing 110A may further pivot about joint 112Ato rotatably move away from housing HOB, such as according to path 120 A, so that computing device 100 transitions from the partially open position, such as shown in FIG. IB, to a fully open position, as shown in FIG. 1C.

[0033] Similarly, when computing device 100 is in a closed position, such as shown in FIG. 1 A, joint 108B is positioned in slot 11 IB such that such that there is a gap 114B between a surface of at least a portion of support plate 104B that faces flexible display 102 and at least a portion of interior surface BOB of flexible display 102 that faces housing HOB. When housing HOB pivots about joint 112B to rotatably move away from housing HOB, such as according to path 120B, so that computing device 100 transitions from a closed position to a partially open position, such as shown in FIG. IB, slot 11 IB guides the linear movement of joint 108B along linear path of movement 117B away from side portion 122B of housing HOB. Becausejoint 108B is coupled to end 105B of support plate 104B, the linear movement of joint 108B along linear path of movement 117B away from side portion 122B of housing HOB causes at least a portion of support plate 104B to move towards at least a portion of interior surface 130B of flexible display 102 that faces housing HOB, thereby decreasing gap 114B between a surface of at least a portion of support plate 104B that faces flexible display 102 and at least a portion of interior surface 130B of flexible display 102 that faces housing HOB.

[0034] When computing device 100 is in a partially open position, such as shown in FIG. IB, housing 110A of computing device 100 may further pivot about joint 112Ato rotatably move away from housing HOB and housing 100B of computing device 100 may further pivot about joint 112B to rotatably move away from housing 110A until computing device 100 transitions to a fully open position, such as shown in FIG. 1C. As housing 110A rotates away from housing HOB, slot 111 A may continue to guide the linear movement of joint 108 A along linear path of movement 117A away from side portion 122 A of housing 110A and cause at least a portion of support plate 104 A to move towards at least a portion of interior surface BOB of flexible display 102 that faces housing 110A until support plate 104A meets a portion of interior surface BOB of flexible display 102. Similarly, as housing HOB rotates away from housing 110A, slot 11 IB may continue to guide the linear movement of joint 108B along linear path of movement 117B away from side portion 122B of housing HOB and cause at least a portion of support plate 104B to move towards at least a portion of interior surface BOB of flexible display 102 that faces housing HOB until support plate 104B meets a portion of interior surface BOB of flexible display 102.

[0035] As shown in FIG. 1C, when computing device 100 is in the fully open position, flexible display 102 may be fully unfolded into a flat surface, and support plates 104A and 104B may each meet a portion of interior surface BOB of flexible display 102 to provide support for flexible display 102. As such, when computing device 100 is in the fully open position, there may no longer be a gap between flexible display 102 support plates 104A and 104B. When computing device 100 is in the fully open position, housing HOA and housing HOB may pivot about joints 112A and 112B, respectively, to rotatably move back towards each other to transition computing device 100 from the fully open position to a partially open position, such as shown in FIG. IB, and from the partially open position to a closed position, such as shown by FIG. 1 A.

[0036] To transition computing device 100 from the fully open position to a partially open position or a closed position, housing HOA of computing device 100 may pivot about joint 112Ato rotatably move towards housing HOB, and housing 100B of computing device 100 may pivot about joint 112B to rotatably move towards housing 110A until computing device 100. As housing 110A rotates towards housing HOB, support plate 104 A may correspondingly pivot about joint 106 A, and slot 111 A may guide the linear movement of joint 108 A along linear path of movement 117A away from flexible display 102, thereby causing at least a portion of support plate 104Ato move away from flexible display 102. Similarly, as housing HOB rotates towards housing 110A, support plate 104B may correspondingly pivot about joint 106B, and slot 11 IB may guide the linear movement of joint 108B along linear path of movement 117B away from flexible display 102, thereby causing at least a portion of support plate 104B to move away from flexible display 102.

[0037] In this way, as shown in FIGS. 1A-1C, slide modules 116A-116B guides the movement of support plates 104 A and 104B and the distance between flexible display 102 and support plates 104A and 104B such that they may fully support flexible display 102 when flexible display 102 is in the fully open position, such as shown in FIG. 1C while creating gaps 114A and 114B between flexible display 102 and support plates 104A and 104B when flexible display 102 is folded, such as shown in FIG. 1A, thereby leaving room for the folded area of flexible display 102 to bulge outwards towards support plates 104 A and 104B. The guided movement of support plates 104 A and 104B away from flexible display 102 as flexible display 102 is folded may minimize the amount of stress that is applied by support plates 104A and 104B to flexible display 102 when flexible display 102 is folded, thereby increasing the reliability and longevity of flexible display 102.

[0038] As can be seen in FIGS. 1A-1C, the hinge structure of support plate 104A may include joint 106 A, joint 108 A, and slide module 116A. Similarly, the hinge structure of support plate 104B may include joint 106B, joint 108B, and slide module 116B. Following the Grubler formula F = 3(A — 1) — Ciji, where F is the degree of freedom, N is the quantity of linkages, and Ci Ji is the degree of constraint by each joint, the hinge structure of support plate 104 A and the hinge structure of support plate 104B may each have 1 degree of freedom.

[0039] In this way, the hinge structure of support plate 104Athat includes joint 106A, joint 108 A, and slide module 116A guides the movement of support plate 104 A towards flexible display 102 as housing 100A moves away from housing 100B, such that support plate 104A meets flexible display 102 when computing device 100 is in a fully open position, and guides the movement of support plate 104B away from flexible display 102 as housing 100A moves towards housing 100B, such that there is a gap 114A between support plate 104A and flexible display 102 when computing device 100 is in a closed position. Similarly, the hinge structure of support plate 104B that includes joint 106B, joint 108B, and slide module 116B guides the movement of support plate 104B towards flexible display 102 as housing 100B moves away from housing 100A, such that support plate 104B meets flexible display 102 when computing device 100 is in a fully open position, and guides the movement of support plate 104B away from flexible display 102 as housing 100B moves towards housing 100A, such that there is a gap 114B between support plate 104B and flexible display 102 when computing device 100 is in a closed position. The guided movement of support plates 104 A and 104B away from flexible display 102 as flexible display 102 is folded may minimize the amount of stress that is applied by support plates 104A and 104B to flexible display 102 when flexible display 102 is folded, thereby increasing the reliability and longevity of flexible display 102. [0040] FIGS. 2A-2F are conceptual diagrams illustrating a cross-sectional profile view of an example computing device having a flexible display and an autolocking cam system, in accordance with one or more aspects of this disclosure. A computing device may include an autolocking cam system that locks support plates when the computing device is in a closed position, such as shown in FIG. 1 A, or in a fully open position, such as shown in FIG. 1C. The autolocking cam system may stabilize the support plates as well as the position of the housings of the computing device when the computing device is fully open or closed.

[0041] As shown in FIG. 2A, computing device 200, which is an example of computing device 100 shown in FIGS. 1A-1C, may include housings 210A, 210B, and 210C and flexible display 202 coupled to housings 210A and 210B. Slide module 216A is coupled to housing 210A and slide module 216B is coupled to housing 210B.

[0042] Support plates 204 A may be coupled to j oint 206 A via connector 226 A at end 203 A of support plate 204A and may pivot about joint 206A. Support plate 204A may be coupled to joint 208 A at end 205 A of support plate 204A distal from end 203 A via connector 218 A. Slot 211 A of slide module 216A accepts at least a portion of joint 208 A to guide the movement of joint 208 A along linear path of movement 217A, thereby guiding the movement of at least a portion of support plate 204A as support plate 204A pivots about joint 206 A. [0043] Similarly, support plates 204B may be coupled to joint 206B via connector 226B at end 203B of support plate 204B and may pivot about joint 206B. Support plate 204B may be coupled to joint 208B at end 205B of support plate 204B distal from end 203B via connector 218B. Slot 211B of slide module 216B accepts at least a portion of joint 208B to guide the movement of joint 208B along linear path of movement 217B, thereby guiding the movement of at least a portion of support plate 204B as support plate 204B pivots about joint 206B.

[0044] Computing device 200 may include an autolocking system that includes cam 252Athat is coupled to joint 206A and spring-loaded pin 258A, where spring-loaded pin 258A may be coupled to or contained by joint module 215, which is similar to joint module 115 of FIGS. 1A-1C. Cam 252 A may be a rotating component, such as a cylindrical-shaped shaft, that rotates about joint 206 A so that exterior surface 254 A of cam 252 A rotates about joint 206 A. In some examples, cam 252 A may encircle joint 206A.

[0045] Cam 252A may be coupled to support plate 204A, such as by being a cylindrical portion of connector 226A coupled to end 203 A of support plate 204Ato joint 206A. Cam 252 A may be coupled to joint 206 A, such as by at least partially enclosing joint 206 A, and may rotate about a longitudinal axis of joint 206A. As such, when support plate 204A pivots about joint 206 A, cam 252 A may correspondingly rotate according to the pivotal movement of support plate 204A and may rotates in correspondence with pivot movement of support plate 204A. Similarly, cam 252B may be coupled to support plate 204B, such as by being a cylindrical portion of connector 226B coupled to end 303B of support plate 204B to joint 206 A. Cam 252B may be coupled to joint 206B, such as by at least partially enclosing joint 206B, and may rotate about a longitudinal axis of joint 206B. As such, when support plate 204B pivots about joint 206B, cam 252B may correspondingly rotate according to the pivotal movement of support plate 204B and may rotates in correspondence with pivot movement of support plate 204B.

[0046] Exterior surface 254A of cam 252A includes concave portions 256A-1 and 256A- 2 for accepting spring-loaded pin 258A. Specifically, concave portion 256A-1 may accept spring-loaded pin 258A when computing device 200 is in a closed position, such as shown in FIG. 2A, to stabilize support plate 204A and to lock computing device 200 in the closed position. Locking computing device 200 in a closed position, as discussed in this disclosure, does not mean that spring-loaded pin 258 A permanently fixes computing device 200 in a closed position when concave portion 256A-1 of cam 252A accepts spring-loaded pin 258A. Instead, spring-loaded pin 258A and concave portion 256A-1 of cam 252A may increase the amount of force that may be required in order for a user to rotate housing 210Ato move computing device 200 from a closed position to a partially open position and/or a fully open position.

[0047] When housing 210A rotates outwards to transition computing device 200 from a closed position, such as shown in FIG. 2A, to a partially open position, such as shown in FIG. 2B, the cam 252A may rotate in a counter-clockwise direction according to the movement of support plate 204A so that concave portion 256A-1 of cam 252Ais no longer lined up to accept spring-loaded pin 258 A. Instead, exterior surface 254 A of cam 252A between concave portions 256A-1 and 256A-2 of cam 252A pushes against spring- loaded pin 258 A, thereby no longer locking computing device 200 in the closed position and reducing the amount of force necessary for a user to rotate housing 210Ato move computing device 200 from the partially open position back to the closed position shown in FIG. 2A or to a fully open position shown in FIG. 2C.

[0048] When housing 210A rotates outwards to transition computing device 200 from a partially open position, such as shown in FIG. 2B, to a fully open position, such as shown in FIG. 2C, concave portion 256A-2 of cam 252A may be lined up to accept spring- loaded pin 258 A, thereby locking computing device 200 in the fully open position.

[0049] Similarly, when housing 210A rotates towards housing 210B to transition computing device 200 from a fully open position, such as shown in FIG. 2C, to a partially open position, such as shown in FIG. 2B, the cam 252A may rotate in a clockwise direction according to the movement of support plate 204A so that concave portion 256A- 2 of cam 252A is no longer lined up to accept spring-loaded pin 258A. Instead, exterior surface 254A of cam 252A between concave portions 256A-1 and 256A-2 of cam 252 A pushes against spring-loaded pin 258 A, thereby no longer locking computing device 200 in the open position and reducing the amount of force necessary for a user to rotate housing 210Ato move computing device 200 from the partially open position back to the closed position shown in FIG. 2A or to a fully open position shown in FIG. 2C.

[0050] When housing 210A rotates towards housing 210B to transition computing device 200 from a partially open position, such as shown in FIG. 2B, to a closed position, such as shown in FIG. 2A, concave portion 256A-1 of cam 252Amay be lined up to accept spring-loaded pin 258 A, thereby locking computing device 200 in the closed position.

[0051] Similarly, as shown in FIGS. 2D-2F, an autolocking system may include cam 252B that is coupled to joint 206B and spring-loaded pin 258B, where spring-loaded pin 258B may be coupled to or contained by joint module 115. Cam 252B may be a rotating component, such as a cylindrical-shaped shaft, that rotates about joint 206B so that exterior surface 254B of cam 252B rotates about joint 206B. In some examples, cam 252B may encircle joint 206B.

[0052] As described above, cam 252B may be coupled to support plate 204B, such as by being a cylindrical portion of connector 226B coupled to end 103B of support plate 204B to joint 206 A. Cam 252B may be coupled to joint 206B, such as by at least partially enclosing joint 206B, and may rotate about a longitudinal axis of joint 206B. As such, when support plate 204B pivots about joint 206B, cam 252B may correspondingly rotate according to the pivotal movement of support plate 204B.

[0053] Exterior surface 254B of cam 252B includes concave portions 256B-1 and 256B-2 for accepting spring-loaded pin 258B. Specifically, concave portion 256B-1 may accept spring-loaded pin 258B when computing device 200 is in a closed position, such as shown in FIG. 2D, to stabilize support plate 204B and to lock computing device 200 in the closed position. Locking computing device 200 in a closed position, as discussed in this disclosure, does not mean that spring-loaded pin 258B permanently fixes computing device 200 in a closed position when concave portion 256B-1 of cam 252B accepts spring-loaded pin 258B. Instead, spring-loaded pin 258B and concave portion 256B-1 of cam 252B may increase the amount of force that may be required in order for a user to rotate housing 210B to move computing device 200 from a closed position to a partially open position and/or a fully open position.

[0054] When housing 210B rotates outwards to transition computing device 200 from a closed position, such as shown in FIG. 2D, to a partially open position, such as shown in FIG. 2E, the cam 252B may rotate in a clockwise direction so that concave portion 256B- 1 of cam 252B is no longer lined up to accept spring-loaded pin 258B. Instead, exterior surface 254B of cam 252B between concave portions 256B-1 and 256B-2 of cam 252B pushes against spring-loaded pin 258B, thereby no longer locking computing device 200 in the closed position and reducing the amount of force necessary for a user to rotate housing 210B to move computing device 200 from the partially open position back to the closed position shown in FIG. 2D or to a fully open position shown in FIG. 2F.

[0055] When housing 210B rotates outwards to transition computing device 200 from a partially open position, such as shown in FIG. 2E, to a fully open position, such as shown in FIG. 2F, concave portion 256B-2 of cam 252B may be lined up to accept spring-loaded pin 258B, thereby locking computing device 200 in the fully open position. [0056] Similarly, when housing 200B rotates towards housing 210Ato transition computing device 200 from a fully open position, such as shown in FIG. 2F, to a partially open position, such as shown in FIG. 2E, the cam 252B may rotate in a counter-clockwise direction according to the movement of support plate 204B so that concave portion 256B -2 of cam 252B is no longer lined up to accept spring-loaded pin 258B. Instead, exterior surface 254B of cam 252B between concave portions 256B-1 and 256B-2 of cam 252B pushes against spring-loaded pin 258B, thereby no longer locking computing device 200 in the open position and reducing the amount of force necessary for a user to rotate housing 210B to move computing device 200 from the partially open position back to the closed position shown in FIG. 2D or to a fully open position shown in FIG. 2F.

[0057] When housing 210B rotates towards housing 210Ato transition computing device 200 from a partially open position, such as shown in FIG. 2E, to a closed position, such as shown in FIG. 2D, concave portion 256B-1 of cam 252B may be lined up to accept spring-loaded pin 258B, thereby locking computing device 200 in the closed position. [0058] In some examples, a computing device, such as computing device 100 shown in FIGS. 1A-1C and computing device 200 shown in FIGS. 2A-2F, may use gears to synchronize the movement of housings of the computing device (e.g., housing 210A and housing 210B of computing device 200), so that housing 210A and housing 210B may concurrently rotate away from each other or towards each other at the same speed. That is, the gears may prevent housing 210A and housing 210B to concurrently rotatably move at different speeds, and may prevent, for example, housing 210Ato rotatably move toward housing 210B while housing 210B remains stationary or while housing 210B is rotatably moving away from housing 210A. Synchronizing the movement of housing 210A and housing 210B may help prevent potential damage to flexible display 202.

[0059] FIGS. 3 A and 3B are conceptual diagrams illustrating a cross-sectional profile view of an example computing device having gears for synchronizing the movement of the housings of the computing device, in accordance with one or more aspects of this disclosure.

[0060] As shown in FIG. 3A, computing device 300, which is an example of computing device 100 shown in FIGS. 1A-1C and computing device 200 shown in FIGS. 2A-2F, may include housings 310A, 310B, and 310C and flexible display 302 coupled to housings 310A and 310B. Slide module 316A is coupled to housing 310A and slide module 316B is coupled to housing 310B . [0061] Support plates 304Amay be coupled to a joint at end 303A of support plate 304A and may pivot about the joint. Support plate 304 A may be coupled to joint 308 A at end 305 A of support plate 304A distal from end 303 A via connector 318A. Slot 311 A of slide module 216A accepts at least a portion of joint 308 A to guide the movement of joint 308 A along linear path of movement 317A, thereby guiding the movement of at least a portion of support plate 304A as support plate 304A pivots.

[0062] Similarly, support plates 304B may be coupled to joint 206B via connector 226B at end 303B of support plate 304B and may pivot about joint 206B. Support plate 304B may be coupled to joint 308B at end 305B of support plate 304B distal from end 303B via connector 318B. Slot 311B of slide module 216B accepts at least a portion of joint 308B to guide the movement of joint 308B along linear path of movement 317B, thereby guiding the movement of at least a portion of support plate 304B as support plate 304B pivots.

[0063] Gear 362Amay be a circular gear coupled to support plate 304A, such as by being a portion of connector 336Athat couples to end 303 A of support plate 304A. Gear 362A may rotate about axis 356A, and the rotation of gear 362A may therefore correspond to the pivot movement of support plate 304A. For example, gear 362Amay rotate counterclockwise as computing device 300 is opened and may rotate clockwise as computing device 300 is closed.

[0064] Similarly, gear 362B may be a circular gear coupled to support plate 304B, such as being a portion of connector 336B that couples to end 303B of support plate 304B. Gear 362B may rotate about axis 356B, and the rotation of gear 362B may therefore correspond to the pivot movement of support plate 304B. For example, gear 362B may rotate clockwise as computing device 300 is opened and may rotate clockwise as computing device 300 is closed.

[0065] Gear 362Amay mesh with gear 354A and gear 362B may mesh with gear 354B, where each of gears 354A and 354B may also be circular gears contained in or coupled to joint module 315. That is, the teeth of gear 362Amay mesh with the teeth of gear 354A, and the teeth of gear 362B may mesh with the teeth of gear 354B. Further, gear 354 A may mesh with gear 354B, so that the teeth of gear 354 A may mesh with the teeth of gear 354B. In some examples, the center of each of gears 362 A, 362B, 354 A, and 354B may form a straight line.

[0066] Thus, when computing device 300 in the closed position is opened, such as when housing 310A pivots to rotate away from housing 310B, gear 362 A may rotate in a counter-clockwise direction, thereby causing gear 354Ato rotate in a clockwise direction. Similarly, when computing device 300 in the closed position is opened, and housing 310B pivots to rotate away from housing 310A, gear 362B may rotate in a clockwise direction, thereby causing gear 354B to rotate in a clockwise direction.

[0067] Because gear 354 A and 354B are meshed with each other, and because gears 354A and 354B are also meshed with gears 362A and 354B, respectively, the rotational movements of housing 310A and housing 310B are thereby synchronized. That is, because the speed and the amount of rotation of gears 362A and 362B are synchronized, the speed and amount of rotational movements of housing 310A and housing 310B are thereby also synchronized.

[0068] As shown in FIG. 3B, gears 362 A and 362B and gears 354 A and 354B may synchronize the movements of housing 310A and housing 310B so that computing device 300 transitions from being in a closed position, as shown in FIG. 3 A to being in a partially open position, as shown in FIG. 3B. Due to housing 310A and housing 310B being synchronized via gears 362 A and 362B and gears 354 A and 354B, the angle between housing 310A and centerline 360 may always be the same as the angle between housing 310B and centerline 360 as housing 310A and housing 310B rotatably moves to transition computing device 300 between a closed position and an open position.

[0069] FIG. 4 is a conceptual diagram illustrating an exploded view of an example joint module 415 in further detail, in accordance with some aspects of the present disclosure. As shown in FIG. 4, joint module 415 may be an example of joint module 115 of FIGS.

1 A- 1C, joint module 215 of FIGS. 2A-2F, and joint module 315 of FIGS. 3A and 3B. Joint module 415 may include joints 412A and 412B, which may be examples of 112A and 112B, respectively, of FIGS. 1A-1C, that may couple to housing HOA and housing HOB of computing device 100 of FIGS. 1A-1C.

[0070] Joint module 415 may accept cam 452 A and spring-loaded pin 458 A, where pin 402A may operably couple and/or connect cam 452A to joint module 415. Pin 402Ais an example of joint 106A of FIGS. 1A-1C, and cam 452A may rotate about a longitudinal axis of pin 402A. As shown in FIG. 4, cam 452A may include a parallel set of concave portions 456A-2 for accepting spring-loaded pin 458A. In some examples, cam 452A is an example of cam 252 A of FIGS. 2A-2F, and spring-loaded pin 458 A may be example of spring-loaded pin 258A of FIGS. 2A-2F.

[0071] Similarly, joint module 415 may accept cam 4252B and spring-loaded pin 458B, where pin 402B may operably couple and/or connect cam 452B to joint module 415. Pin 402B is an example of joint 106B of FIGS. 1A-1C, and cam 452B may rotate about a longitudinal axis of pin 402B. In some examples, cam 452B is an example of cam 252B of FIGS. 2A-2F, and spring-loaded pin 458B may be example of spring-loaded pin 258B of FIGS. 2A-2F.

Pin 572A may be inserted into connector 518A and a slot (not shown in FIG. 5) of slide module 516A, where the slot of slide module 516A guides the movement of pin 572A along a linear path within slide module 516A.
