Description:
Improved wireless charging station

FIELD OF THE INVENTION

[0001] The present invention relates to an improved wireless charging station. BACKGROUND TO THE INVENTION

[0002] It is common for a person or household to have several chargeable devices, for example, a smart phone, tablet, watch, and headphones. Traditionally each of these items were charged individually by a cord attaching to the device to a power source. Advances in technology have allowed wireless charging by providing a station comprising a base or plate on which the device can be placed, and wherein the base is attached by cord to the power source. The device is then placed on the base and wirelessly charged.

[0003] The advantage of such wireless charging is flexibility and ease of use, in which the device can be easily placed on and removed from the station, eliminating the need for the constant plugging and unplugging for power cords from the device. Depending on the size of the station, it also allows for the charging of multiple devices at once.

[0004] However, current wireless charging stations contain a flat surface wherein the devices must each be placed flat upon the base. The disadvantage of this configuration is that the devices can easily be knocked off the base, therefore interrupting the charging process, and also creates difficulty if the user needs to use the device during the charging process.

[0005] The flat surface can create an issue with the viewing angle because wireless charging requires that the device and the charging surface are usually no more than a few millimetres apart. This means that the device's display is often not at a desired interaction distance and orientation because the display is flat on the charging surface. This requires the user to hunch over the device to interact with it while on the charging surface.

[0006] It would be advantageous for a wireless charging station with an upright base to allow for easy use during charging, and also to reduce likelihood of the devices being accidently moved from the station.

[0007] The object of this invention is to provide a wireless charging station to alleviate the above problems, or at least provide the public with a useful alternative.

SUMMARY OF THE INVENTION

[0008] In a first aspect the invention comprises a base adapted to engage and support an upright wireless charging stand, wherein the stand includes a plurality of induction coils that transfer energy from the charger to at least one receiver device, such as a smartphone via electromagnetic induction, and the stand includes an indent allowing an additional device such as an watch to be attached to the stand.

[0009] It should be noted that any one of the aspects mentioned above may include any of the features of any of the other aspects mentioned above and may include any of the features of any of the embodiments described below as appropriate.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The following detailed description of the invention refers to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts. Dimensions of certain parts shown in the drawings may have been modified and/or exaggerated for the purposes of clarity or illustration.

[0017] The present invention provides an improved wireless charging station wherein the stand is in an upright position allowing for use of the device while charging, and wherein the stand allows for multiple devices to be charged at once, including the attachment of a watch device.

[0018] It is to be understood that in the description the invention is in a preferred embodiment adapted for use with Apple products such as iPhone, iPad, Air Pods and Apple Watch, however the invention can be adapted for use with other smart technologies and devices produced by other companies such as Samsung and Google.

[0019] Turning now to the drawings, Figure 1 illustrates an expanded view of the relevant components of the charging station 20 including a first and second plate 22 and 24 to form a base 26, and an induction coil plate 28, backing element 30, front and rear cover plates 32 and 34 to form a stand 36.

[0020] The coil plate 28 contains a plurality of induction coils 38 placed to correspond to relevant devices, with larger coils for the charging of larger items such as a smartphone or tablet, and smaller coils for the charging of smaller items such as earbuds and watch devices. In the preferred embodiment, the coil plate 28 contains one large coil and two small coils.

[0021] The coil plate 28 is attached to the backing element 30 by screws 40, and the front and rear cover plates 32 and 34 are also attached to the backing element 30 by screws 40. Accordingly, the charging stand is formed with the backing element 30 housing the induction coil plate 28, with the front cover plate 32 extended over the front of the backing element 30, and the rear cover plate 34 extended over the rear of the backing element 30.

[0022] The charging stand 36 is primarily rectangular shaped with the base of the stand containing a first notch 42 and second notch 44. It also contains an indent 46, and in the preferred embodiment, the indent 46 is positioned between the two smaller coils and adjacent to the larger coil. [0023] The first base plate 22 is primarily rectangular in shape and contains a notch which corresponds to the first notch 42 on the stand 36. The second base plate 24 is also primarily rectangular in shape and contains a notch which corresponds to the second notch 44 on the stand 26. The first and second plates are therefore connected through alignment of the relevant first and second notches to form the base 26 and secure it to the stand 36. The base may also contain a trench 48 allowing for the placement of electronic devices on the base 26 and flush against the front of the stand 36.

[0024] The charging station 20 is illustrated in Figures 2 and 3. The station 20 can therefore be placed upright on a surface and connected to a power source via a cord (not shown) which can be plugged into the socket 50 on the rear of the stand 36. Power is transmitted from the source along the cord and into the charging station and induction coils, creating an electromagnetic field which interacts with the receiver coils located in the electronic device, charging its battery. Accordingly, when electronic devices are placed on the station 20 as seen in Figure 4, they can be charged without the need to plug the cord into the device to receive power. As such, multiple devices can be charged at any one time.

[0025] The particular advantage of the present invention is the configuration of the station 20 and the shape of the stand 36. As can be seen in Figure 4, a smart phone (iPhone) 52 has been placed on the trench 48 located on the base 26 to prevent movement during charging. The back of the phone 52 is propped up against the front cover plate, corresponding to the larger coil 38 within the stand 36. Accordingly it receives the highest level of charge, as the larger coil will create a larger electromagnetic field, increasing the efficiency of the charge and also increasing the distance that the charge can travel.

Accordingly, if the phone 52 is jostled or its position is rearranged, the larger coil and therefore greater magnetic field will still allow for continuous charging.

[0026] It is to be understood that the invention can also be adapted for use with a larger device such as a tablet (iPad).

[0027] The two smaller coils 38 are separated by the indent 46 in the stand 36, allowing for two devices to be placed on the station 20 corresponding to the two smaller coils. An example of such a device is a smart watch (Apple Watch) 54 which can be attached to the stand 36 as shown in Figure 4, by slotting the watch with a closed band onto the portion of the stand 36 above the indent 46. The device component of the watch 54 therefore corresponds to the placement of the first smaller coil 38 within the stand 36, and accordingly charged by the electromagnetic field created by the first corresponding coil. The indent 46 allows the watch to be charged without it having to be laid flat, something that is very advantageous to the user.

[0028] Another device which can be used with the invention is earbuds (Air Pods) within a chargeable case 56 as illustrated in Figure 4. The case 56 is placed within the trench 48 on the base 26 and propped up against lower portion of the stand 36 below the indent 46. The earbuds case 56 therefore corresponds to the placement of the second smaller coil 38 within the stand 36, and accordingly charged by the electromagnetic field created by the second smaller coil.

[0029] Accordingly, the use three coils to correspond to three devices allows for the concurrent and efficient charging of all the devices, with the size of the coil proportional to the size of the corresponding device.

[0030] Of course it is to be understood that the charging station may be of any size and may contain multiple coils to charge more than three devices at a time. Thus two smartphones may be able to be charged instead of just one.

[0031] All of the device screens face towards the user, allowing for use during charging. The upright positioning of the stand 36 allow for ease of use as the position mimics that of the device when it is held in the hand or positioned on the wrist. As such, the user can easily interact with the device without craning over the screen laid flat on a charging surface, and the position of the device either attached to the stand 36 or held in the trench 48 reduces the likelihood of movement while the device is being used.

[0032] It is rather common for user to desire extended interaction with the device whilst the charge is low, forcing them to remain in close proximity to the device while charging. The position of the upright stand increases user comfort, as the user could easily place the device onto the charging station located on a table or bench, and make calls or watch video on the device while the charging is in process.

[0033] In an alternate embodiment illustrated in Figure 5 there are two main induction coils for charging a phone either in a portrait or landscape orientation, the latter allowing the user for example to watch a video while the phone is being charged. Thus the bottom coil is slightly positioned more to the right then the top coil.

[0034] In addition rather than having two base plates there is only one central base plate 58 that engages slot 60 on the central element 30. The slot incudes no slip silica strips that help keep the base and the central element together. A further indent strip 66 is used to keep the phone in place on the charging station.

[0035] A cavity 68 is also provided in this embodiment to support an apple watch.

[0036] The reader will now appreciate the present invention which provides a wireless charging station for multiple electronic devices, allowing for the simultaneous charging of all devices at one time, the devices in a position allowing for ease of use while charging, and in particular the presence of an indent allowing for the attachment of a smart watch. The device may also include a USB port for external charging.
