[0032] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present invention, rather than to limit the scope of protection of the present invention.

[0033] Figure 1 FIG. 1 is a schematic structural diagram of a steering wheel 100 according to an exemplary embodiment of the present invention. Figure 1 As shown, the steering wheel 100 includes a rim 101 , a hub 102 , and spokes 103 connecting the rim and the hub. The number of the spokes 103 is not limited to three as shown.

[0034] The steering wheel 100 may include a fixed rim portion 1 and a deformable rim portion 2, wherein the fixed rim portion 1 may be connected to the hub 102 via corresponding spokes and is therefore fixed relative to the hub 102. The fixed rim portion 1 has a receiving space S inside. The deformable rim portion 2 may at least partially move relative to the fixed rim portion 1 and at least partially retract into the receiving space S of the fixed rim portion 1, and is particularly configured to be able to at least partially retract into the receiving space S of the fixed rim portion 1 to change the geometrical characteristics.

[0035] In the prior art, there is a solution that uses the flexible part of the steering wheel rim to be pulled toward the hub direction to deform the flexible part, thereby achieving a change in the appearance of the steering wheel. However, the embodiment of the present invention provides a different technical concept, that is, the overall shape of the rim 101 of the steering wheel 100 is changed by changing the geometric characteristics of the deformable rim portion 2 of the steering wheel 100 during the process of shrinking into the receiving space S of the fixed rim portion 1, that is, the appearance of the steering wheel 100 is changed. In other words, the change in the appearance of the steering wheel 100 is based on the shrinking action of the deformable rim portion 2 into the fixed rim portion 1 itself, rather than based on the pulling operation of the deformable rim portion 2 toward the hub direction as in the prior art.

[0036] The deformable rim portion 2 may be made of a flexible material, and the elastic modulus of the flexible material may be specifically set so that the flexible material has a predetermined rigidity and can change shape under tension. Thus, the deformable rim portion 2 can be convenient for the user to hold and operate, and can be tensioned when at least partially retracted into the receiving space S of the fixed rim portion 1, thereby changing shape by utilizing the properties of the flexible material, thereby achieving a change in the appearance of the steering wheel 100.

[0037] To this end, in some embodiments, such as Figure 1 and Figure 2 As shown, the steering wheel 100 may further include a driving mechanism 3 and a stopping mechanism 4. The driving mechanism 3 is connected to the first end of the deformable rim portion 2 and is used to drive the deformable rim 2 to move at least partially relative to the fixed rim portion 1. The stopping mechanism 4 is connected to the second end of the deformable rim portion 2 opposite to the first end and is used to selectively lock the second end of the deformable rim portion 2 relative to the fixed rim portion 1. Thus, by controlling the operation of the driving mechanism 3 and the stopping mechanism 4, the deformable rim portion 2 can be made to change its geometric characteristics when at least partially retracted into the receiving space S of the fixed rim portion 1, in particular, to be tensioned and change its shape.

[0038] For example, the driving mechanism 3 can drive the deformable rim portion 2 to retract toward the fixed rim portion 1 through the first end of the deformable rim portion 2, but the stop mechanism 4 can lock the second end of the deformable rim portion 2 relative to the fixed rim portion 1 to prevent the second end of the deformable rim portion 2 from moving, thereby the deformable rim portion 2 can be tensioned and change shape due to the deformable property. When the stop mechanism 4 is operated to release the lock on the second end of the deformable rim portion 2, under the action of the driving mechanism 3, the deformable rim portion 2 can be at least partially, especially completely retracted into the fixed rim portion 1.

[0039] Preferably, the drive mechanism 3 may include a drive motor arranged in the fixed rim portion 1 (e.g., arranged in the receiving space S). Thus, the drive motor is not visible outside the steering wheel, i.e., is hidden. The drive mechanism 3 may be connected to the first end of the deformable rim portion 2 in various suitable ways.

[0040] Additionally or alternatively, the stop mechanism 4 may be arranged on the fixed rim portion 1, and is preferably configured to be able to be snap-connected with the second end of the deformable rim portion 2. For example, the stop mechanism 4 may be implemented as a snap-in groove provided on the inner surface of the fixed rim portion 1, and the second end of the deformable rim portion 2 may be provided with a snap-in, which may be snapped into the snap-in groove to lock the second end of the deformable rim portion 2 relative to the fixed rim portion 1. Thus, a simple and economical snap-in connection may be achieved. However, the present invention is not limited thereto, and other suitable devices such as electromagnetic switches may also be used to achieve the corresponding connection.

[0041] By changing the geometrical features of the deformable rim portion 2 , the steering wheel 100 can have a first steering wheel mode and a second steering wheel mode that are different from each other. Figure 1 and Figure 3 The two steering wheel modes are shown respectively. As shown in the figure, in the two steering wheel modes, the exposed part of the deformable rim portion 2 and the fixed rim portion 1 form a circumferentially closed steering wheel rim 101. Here, the exposed part of the deformable rim portion 2 refers to the part thereof exposed outside the fixed rim portion 1, that is, the part that is not retracted into the fixed rim portion 1.

[0042] In particular, if Figure 1 As shown, in the first steering wheel mode, the exposed portion of the deformable rim portion 2 is in an arc shape, thereby realizing a circular steering wheel; Figure 3 As shown, in the second steering wheel mode, the exposed portion of the deformable rim 2 is in a straight line, thereby realizing a so-called sports steering wheel. Compared with a round steering wheel, a sports steering wheel can expand the driver's field of vision above the steering wheel and free up the driver's leg space below the steering wheel, thereby improving the driver's driving experience.

[0043] Furthermore, in some embodiments, the steering wheel 100 may also have a third steering wheel mode, wherein the deformable rim portion 2 is at least partially, preferably completely, retracted into the receiving space of the fixed rim portion 1 to form a circumferentially open steering wheel rim 101 . Figure 4 The appearance of the steering wheel in this mode is shown. Thus, the driving experience of the driver can be further improved on the basis of the sports steering wheel.

[0044] In addition, the second steering wheel mode and the third steering wheel mode can also correspond to different vehicle driving modes, such as game modes, so that users can effectively experience the feeling of racing car driving and the feeling of driving a vehicle in a game through steering wheels with different appearances. In this case, the second steering wheel mode and the third steering wheel mode are preferably entered only when parking to ensure driving safety.

[0045] Reference Figure 1 In some embodiments, the steering wheel 100 may further include a locking unit 5 as shown highly schematically in the figure, which is configured to be selectively connected to the deformable rim portion 2 to restrict the movement of the deformable rim portion 2 at least partially relative to the fixed rim portion 1. That is, when the locking unit 5 is in a locked state, even if the stop mechanism 4 is operated to release the lock on the second end of the deformable rim portion 2, the deformable rim portion 2 cannot move and at least partially retract into the receiving space S of the fixed rim portion 1.

[0046] Preferably, the locking unit 5 may be formed in the steering wheel spoke 103 connected to the steering wheel hub 102. For example, the locking unit 5 may be implemented as an end of the steering wheel spoke 103 connected to the deformable rim portion 2 or be arranged at the end, so that when the restriction of the deformable rim portion 2 by the locking unit 5 is released, the deformable rim portion 2 can be retracted into the fixed rim portion 1, for example, by the operation of the driving mechanism 3 and the stopping mechanism 4 as described above. Figure 3 and Figure 4 A portion of the spoke 103 is shown to indicate that the locking unit 5 and / or the spoke 103 are disconnected from the deformable rim part 2 .

[0047] In particular, in some embodiments, the locking unit 5 may be configured to be activated in response to a first input command from a user to disconnect from the deformable rim portion 2. To this end, in some embodiments, the steering wheel 100 may also be provided with a first input device 6 (such as Figure 1 As shown), it is used to receive a first input instruction from a user. For example, the first input device 6 can be implemented as a key.

[0048] Preferably, the locking unit 5 is prohibited from being activated when the vehicle is traveling. That is, when the vehicle is traveling, even if the first input device 6 receives the first input instruction, the locking unit 5 will not be activated. Thus, the false triggering of the locking unit 5 can be avoided, thereby avoiding the unexpected appearance change of the steering wheel and the confusion and distraction caused to the user, thereby ensuring driving safety. To this end, it can be determined by determining (e.g., detecting) the driving speed of the vehicle to determine whether the vehicle is traveling, which is achieved, for example, by a controller of the vehicle based on a preset program.

[0049] In some embodiments, the steering wheel 100 may also be configured to switch the corresponding steering wheel mode in response to a second input instruction from the user only when the locking unit 5 is activated. That is, the second input instruction is associated with the steering wheel mode, and the desired steering wheel mode can be determined by the content of the second input instruction. Here, in particular, the setting that the steering wheel mode can be switched in response to the second input instruction only when the locking unit 5 is activated may include receiving the first input instruction through the first input device 6, and determining that the locking unit 5 has been activated by appropriate means. Thereby, unnecessary structural failure can be avoided. For this purpose, the drive mechanism 3 and the stop mechanism 4 can be arranged to operate accordingly in response to the second input instruction from the user only when the locking unit 5 is activated.

[0050] In some embodiments, the steering wheel 100 may also be provided with a second input device 7 (such as Figure 1Preferably, the second input device 7 is formed as a single key, and different key press times correspond to different steering wheel modes.

[0051] For example, in some embodiments, the first input device 6 on the steering wheel 100 may be pressed once to activate the locking unit 5, and then the second input device 7 on the steering wheel 100 may be pressed once to make the steering wheel enter the first steering wheel mode, the second input device 7 may be pressed twice to make the steering wheel enter the second steering wheel mode, and the second input device 7 may be pressed three times to make the steering wheel enter the third steering wheel mode. Afterwards, the number of key presses may be reset to start a new cycle, i.e., pressing the second input device 7 four times corresponds to entering the first steering wheel mode.

[0052] In addition, it can be provided that, after a predetermined idle time after entering the first steering wheel mode, the locking unit 5 is automatically connected to the deformable rim part 2 to lock it. This can include the steering wheel spoke 103 with the locking unit 5 being automatically connected to the deformable rim part 2.

[0053] In some embodiments, Figure 1 As shown, the steering wheel 100 may include a first fixed rim portion 11 and a second fixed rim portion 12 arranged oppositely, and a first deformable rim portion 21 and a second deformable rim portion 22 arranged oppositely, the first deformable rim portion 21 cooperates with the first fixed rim portion 11, and the second deformable rim portion 22 cooperates with the second fixed rim portion 12, that is, the first deformable rim portion 21 can be retracted into the first receiving space S1 of the first fixed rim portion 11, and the second deformable rim portion 22 can be retracted into the first receiving space S2 of the second fixed rim portion 12. In the embodiment shown in the figure, in the initial position of the steering wheel, the first fixed rim portion 11 and the second fixed rim portion 12 are arranged oppositely left and right, and the first deformable rim portion 21 and the second deformable rim portion 22 are arranged oppositely up and down.

[0054] In particular, the first deformable rim portion 21 and the second deformable rim portion 22 are respectively retracted into the corresponding receiving space in the same relative movement direction relative to the corresponding fixed rim portion. Figure 1 As shown, the first deformable rim portion 21 and the second deformable rim portion 22 can both be contracted into the fixed rim portion along the arrow direction (i.e. clockwise direction) shown in the figure. Of course, the two can also move relative to the corresponding fixed rim portion along the opposite counterclockwise direction.

[0055] The first deformable rim portion 21 and the second deformable rim portion 22 can move synchronously. This can be achieved by a single drive mechanism.

[0056] But preferably, if Figure 2As shown, the steering wheel 100 may include: a first driving mechanism 31 and a first stopping mechanism 41 for the first deformable rim portion 21; and a second driving mechanism 32 and a second stopping mechanism 42 for the second deformable rim portion 22, the first driving mechanism 32 and the second driving mechanism 42 being arranged on both sides of the steering wheel 100 opposite to each other. In this way, the arrangement of the driving mechanism and the stopping mechanism can be facilitated, and the structure can be simplified. In order to achieve synchronous movement of the first deformable rim portion 21 and the second deformable rim portion 22, the first driving mechanism 31 and the second driving mechanism 32, and the first stopping mechanism 41 and the second stopping mechanism 42 can be controlled simultaneously.

[0057] According to an embodiment of the present invention, a vehicle is further provided, which includes any steering wheel 100 according to the embodiments of the present invention.

[0058] Figure 5 FIG. 2 shows a schematic diagram of the connection of components related to the steering wheel of a vehicle according to an exemplary embodiment of the present invention. Figure 5 As shown, in some embodiments, the vehicle may include a display device 200, and the display device 200 may be configured to display the current steering wheel mode and / or component status information of the steering wheel 100. Here, the display device 200 may be arranged at the center console, for example. In some special embodiments, the display device 200 may also be arranged in the steering wheel 100 or at other holding locations in the vehicle cabin. In particular, the component status information may include the activation state of the locking unit 5. For example, the current steering wheel mode of the steering wheel 100 may be displayed in the display device 200 in graphics and / or text associated with the steering wheel appearance. Displaying the activation state of the locking unit 5 can help the user determine whether the locking unit 5 is activated, for example, whether the first input device 6 receives the first input instruction, and / or whether the first input instruction effectively activates the locking unit 5, and based on this, decide whether to continue pressing the second input device 7.

[0059] Additionally or alternatively, in some embodiments, the vehicle may include a receiving device 300 for receiving a first input instruction and / or a second input instruction from a user. Here, the receiving device 300 is provided separately from the steering wheel 100, that is, the receiving device 300 is not provided on the first input device 6 and the second input device 7 on the steering wheel 100. For example, the receiving device 300 may include at least one of a voice receiving device (such as a microphone), an image receiving device (such as a camera), and a mechanical receiving device (such as a button) inside or outside the vehicle. The receiving device 300 and the first input device 6 and the second input device 7 on the steering wheel 100 may exist separately or in combination. In this way, diversified control of the steering wheel 100 can be achieved.

[0060] Additionally or alternatively, in some embodiments, the operation of the driving mechanism 3 and the stopping mechanism 4 of the steering wheel 100 can be controlled by the vehicle controller 400. Thus, the appearance change of the steering wheel 100 can be controlled by the vehicle controller without providing an additional control unit in the steering wheel 100.

[0061] For example, Figure 5 As shown, the driving mechanism 3, the stop mechanism 4, the locking unit 5, the first input device 6 and the second input device 7 of the steering wheel 100 can be connected to the vehicle controller 400 via the vehicle's CAN bus, thereby enabling the controller 400 to electrically control the components of the steering wheel 100. Other suitable electrical connection methods are also conceivable.

[0062] According to the embodiments of the present invention, the driving pleasure of the driver can be effectively increased by providing a steering wheel design with a changeable appearance, so that customers can effectively experience the feeling of driving a racing car and the feeling of driving a vehicle in a game.
