Description:
DISPLAY FOR ELECTRICAL BIKE

The present invention generically refers to a bike display capable of displaying data or information aboard the bike, in particular a power-assisted (electric) bike.

Today's electric power-assisted bicycles, taken here as example, are sophisticated devices and managed by electronic control units. They also commonly have display devices to inform the rider with data about the route, the motion, the condition of the bicycle or the rider.

Almost always the display devices are mounted on the handlebar, and for weight and size limits they have small dimensions, which forces to create menus to allow access to all of the data. A notable disadvantage is that to select a menu the rider must bring his hand close to the device and press buttons, making the manoeuvre dangerous. Another disadvantage is that the display devices are not symmetrical, ergo left-handed people must operate in a different way than the right-handed.

The main object of the invention is to solve at least one problem of the display devices of the type above.

Another object of the invention is to provide a display device which is simple to use.

These and other objects are achieved by a display device, applicable in particular to power-assisted bicycles, according to claim 1; other advantageous technical features are defined in the dependent claims.

The display device comprises:

an attachment portion to the handlebar of a bicycle,

a display to display data,

an element rotatable with respect to the handlebar attachment portion, an electronic circuit (e.g. with a programmable microprocessor or programmed to execute the actions defined here for the electronic circuit) connected to the display and to the rotatable element so as to detect the angular position of the rotatable element and drive the display according to said angular position, e.g. by changing the information displayed on the display when the rotatable element is rotated by a certain angle, preferably less than a round angle, still more preferably less than a right angle. Preferably, the rotatable element is a ring nut, in particular mounted to form an outer edge of the device.

Preferably the rotatable element is of circular or annular shape, in particular mounted on the external perimeter of the device.

The rotatable element allows the rider to use only one thumb to control the display, so he must not release the grip on the handlebar. Furthermore, given the (preferred) symmetrical nature of the rotatable element, the device is compatible with both left-handed and right-handed people.

Preferably, the electronic circuit is configured to cyclically display a sequence of menus or groups of data as the rotatable element is kept rotating, i.e. the progressive rotation of the rotatable element produces on the display first the appearance of a menu or group of data, then another menu or group of data, and so on up to a last menu or group of data, to then start again from the menu or data group shown first.

Preferably, the rotatable element (or the ring nut) is rotatably mounted on an element detachable with respect to the handlebar attachment portion. So for example the theft of a delicate component is avoided or advantage can be taken of the display for other applications, or one can wear and manoeuvre it like a clock by mounting it on a strap.

Preferably, the rotation axis of the ring nut or of the rotatable element is preferably an axis which in use is or remains substantially vertical, to facilitate manual operations.

Preferably, the detachable element and the handlebar attachment portion comprise mutual non-permanent fixing means, such as Veltro®, magnets or mutually interlocking portions. The non-permanent fixing means present on the detachable element are also useful for attaching the detachable element to other objects, such as a wearable strap or a backpack or another part of the bicycle.

Preferably, the detachable element and the attachment portion are attachable to each other along respective complementary surfaces, on which e.g. said mutual non-permanent fixing means may be present.

Preferably, the display is arranged at the center of the rotatable element (or of the ring), so the display has maximum dimension and the rotatable element (or ring) can stay on the edge, where it is easily operated by a finger. The display, the rotatable element and the electronic circuit may, for example be mounted on the detachable element, so as to make the detachable element an autonomous device, the attachment portion serving then only as an attachment to the bicycle.

Preferably the display consists of a touch screen, to avoid buttons on the device and to provide a control surface close to the ring or the rotatable element.

Preferably the handlebar attachment portion comprises a ring or clamp clampable around or on the handlebar, to facilitate installation on the bicycle.

Preferably, the device comprises aboard an independent battery with which it is electrically powered. In this variant, preferably the detachable element comprises a power socket through which the battery can be recharged or through which it can be recharged by a battery.

Preferably the display is driven by the electronic circuit to display the remaining charge of its battery and/or of an external battery, which powers an electric motor that drives the bicycle. In particular, the device advantageously retains the ability to display the remaining charge also when the detachable element and the handlebar attachment portion are detached from each other. So the detachable element can be reused to display information extraneous to the bike, such as the charging state of the battery that powers the electric motor.

Preferably, the electronic circuit communicates with the outside of the device through a wireless, e.g. radio or GSM or WI-FI, transceiver. A wired connection is however possible, too.

Preferably, the display device comprises a camera. Even more preferably, the camera is mounted oscillating or rotating with respect to the handlebar attachment portion, in particular is rotatably mounted around a (in use) horizontal or vertical axis.

Preferably, the display device comprises a light source. Even more preferably, the light source, e.g. one or several LEDs or a light bulb, is mounted oscillating or rotatable with respect to the handlebar attachment portion; in particular it is rotatably mounted about a (in use) horizontal or vertical axis.

Said (in use) horizontal or vertical axis may be obtained e.g. through an element pivoted on the handlebar attachment portion, where the pivoted element supports the camera and/or the light source.

Another aspect of the invention relates to a bicycle, in particular a power- assisted (electric) bicycle, equipped with the aforementioned display, in one or each of the variants defined herein.

The display device 10 comprises a portion 20 for attaching to the handlebar of a bicycle (not shown), and an element 50, which is preferably detachable with respect to the attachment portion 20.

The attachment portion 20 is formed by a ring or clamp 22 which can be clamped around the handlebar, e.g. with a screw that can tighten it into two enlarged extremities 24 of the ring or clamp 22. The attachment portion 20 may also be made in other ways, e.g. with adhesives, magnets or single screws.

A part of the ring or clamp 22 forms with an extremity 24 an almost flat surface 26, complementary to the lower surface 52 of the element 50. The surface 26 and the surface 52 can be overlapped (Fig. 1) and serve as a positional reference for joining the attachment portion 20 and the element 50. These two pieces are joined (Fig. 1) when the device 10 operates on and for the bicycle, or they can remain separate (Fig. 2) and the element 50 operates independently.

To remain joined, the detachable element 50 and the attachment portion 20 comprise e.g. magnets 70 which attract each other and mutually interlocking portions constituted by two teeth 28 projecting from the ring 22 which can fit inside corresponding seats in the surface 52.

On the detachable element 50 an annular ring nut 54 is mounted rotatably with respect to a fixed circular frame 56, about an axis W.

The axis W is preferably in use an approximately vertical axis.

At the center of the ring nut 54, placed on an (optional) annular support 58, there is a display 60 for displaying data. The display 60 is driven by an electronic circuit (not shown) also connected to the ring nut 58 and mounted on the detachable element 50, e.g. inside the frame 56.

The display 60 is preferably a touch screen.

The electronic circuit preferably comprises a microprocessor programmed to detect the angular position of the ring 58 and drive the display 60 according to this angular position. How the angular position of the ring 58 is detected is not essential: all known systems suitable for the case can be used, e.g. an optical encoder, a potentiometer or sliding electrical contacts.

From the foregoing, it is understood that the rider only needs the thumb to comfortably operate the display 60, e.g. to select menus. When the annular ring 54 is rotated by a certain angle (e.g. by 15 or 20 degrees) the electronic circuit reacts by changing the information displayed on the display 60. Another advantage is therefore the browsing speed of the menus.

Fig. 5 shows an advantageous example of additional use of the element 50.

It can be connected to a battery B, in particular the one mounted on the electric bicycle equipped with the portion 20. For this purpose the battery B comprises equal or compatible electrical connections with (optional) electric terminals present on the bottom of the element 50. These terminals are usable e.g. also to electrically feed the element 50 when it is mounted on the portion 20, which comprises electrical connections that are equal or compatible with the electrical terminals on the bottom of the element 50. The electrical coupling between the element 50 and the battery B advantageously allows, for example, to recharge an (optional) internal battery for supplying the element 50 or to exploit the element 50 to display the state of the battery, such as its percentage of charge or recharge.

Figures 6÷7 show a variant 70 of the display device.

The display device 70 comprises a portion 80 for attachment to the handlebar of a bicycle (not shown), and an element 90, which is detachable with respect to the attachment portion 80.

The attachment portion 80 is formed by one or more rings or clamps 82 which can be clamped around the handlebar, i.e. with a screw. E.g. the rings or clamps 82 are open and can be tightened by tightening screws. The attachment portion 80 may also be made in other ways, e.g. with adhesives, magnets or individual screws.

The attachment portion 80, or the rings or clamps 82 when present, is integral with a central body 84 comprising an almost flat central surface 86, and two lateral projections 88 to which two accessories Al, A2 are rotatably connected.

On the surface 86 there are electrical contacts 100 connectable with respective contacts of a terminal 92 present under the element 90. The electrical contacts 100 feed electrical power to the element 90, which arrives at the portion 80 through a cable PW connected to a battery.

To remain joined, the detachable element 90 and the attachment portion 70 comprise e.g. magnets 70 that attract each other and/or interlocking portions constituted e.g. of the terminal 92.

On the detachable element 90 an annular ring 96 is mounted rotatably with respect to a central fixed frame 98 about an axis W2. The axis W2 is preferably in use an approximately vertical axis.

At the center of the fixed central frame 98 there is a display 99 to display data. The display 99 is driven by an electronic circuit (not shown) also connected to the ring 94 and mounted on the detachable element 90, e.g. inside the frame 98.

The display 99 is preferably a touch screen.

The electronic circuit preferably comprises a microprocessor programmed to detect the angular position of the ring nut 94 and drive the display 99 according to this angular position. How the angular position of the ring 94 is detected is not essential: all known systems suitable for the case can be used, e.g. an optical encoder, a potentiometer or sliding electrical contacts.

From the foregoing, it is understood that the rider only needs the thumb to comfortably operate on the display 99, e.g. to select menus. When the annular ring 94 is rotated by a certain angle (e.g. by 15 or 20 degrees) the electronic circuit reacts by changing the information displayed on the display 99. Another advantage is therefore the browsing speed of the menus.

Each of the two accessories A l, A2 is optional, as is the relative lateral projection 88 which supports it. One or both of the two accessories Al, A2 may also be mounted on the variant of figures 1÷3, e.g. integrally to the portion 20.

The accessory Al is e.g. a body, e.g. in the form of a cylinder or cone, which is rotatable about an horizontal axis A IX, and is equipped with a camera T on its side surface. Thus the camera T can take a shot of the route of the rider in real time, and thanks to the rotation axis A IX, the camera T can be oriented at will. E.g. by turning it towards the saddle of the bicycle the rider can take a shot of himself.

The camera T is connected to an electronic circuit (not shown) that manages the acquisition and/or storing of the images, and which e.g. is installed in the accessory A1 or in the element 90.

The accessory A2 is e.g. a body, e.g. in the form of a cylinder or cone, which is rotatable about an horizontal axis A2X, and is equipped with a light source LD, e.g. a LED source, on its side surface. So the source LD can illuminate the rider's path in real time, and thanks to the rotation axis A2X, the source LD can be oriented at will. E.g. by turning it towards the bicycle saddle the rider can illuminate himself or by turning it towards the front wheel of the bicycle the rider can illuminate the road.

The source LD is connected to an electronic circuit (not shown) which manages the driving thereof, and which e.g. is installed in the accessory A2 or in the element 90.

Preferably, the accessories A1 and A2 are controllable by means of the element 90 or 50, e.g. thanks to dedicated menus selectable by the ring nut 54 or 94.

The electrical contacts 100 and/or the cable PW are optional, since the element 90 can be powered by an internal battery or a battery installed in or on the portion 70.

The organization of information on the display 60 or 99 may be at will.

Preferably, also the element 90 is suitable for coupling with a battery B as in fig. 5.

The camera T and the source LD may also be on the same accessory A 1 or A2, e.g. separated angularly by 180 degrees or 90 degrees, or being aligned along a same horizontal axis.
