At least a portion of the transmission member 12 is rotatably arranged in the mounting hole 111. The steering wheel body 13 is formed with an extension member 131 extending towards the mounting hole 111, at least a portion of the extension member 131 is accommodated in the mounting hole 111 and connected with the transmission member 12, and an outer peripheral wall of the extension member 131 is provided with a second guide portion 1311. The second guide portion 1311 and the first guide portion 1111 are selectively engaged to move the extension member 131 along the first direction when the extension member 131 rotates relative to the housing 11.

[0036] At present, when the vehicle enters the automatic driving mode, the steering wheel occupies a certain internal space of the vehicle, which not only limits the diversity of the vehicle interior design, but also is difficult to meet the needs of passengers for spacious and flexible driving environment. However, the existing steering wheel does not have a folding and shrinking function. Therefore, how to effectively reduce the occupied space of the steering wheel in the automatic driving mode is a technical problem.

[0037] To this end, the present application provides a steering wheel assembly 10, which can reduce the occupied space of the steering wheel body 13 and meet the needs of the driver and passenger for space.

[0038] As Figure 1 , Figure 2 and Figure 4As shown, specifically, the steering wheel assembly 10 can include a housing 11, a transmission member 12 and a steering wheel body 13, the housing 11 can be fixedly connected with a dashboard assembly of a vehicle, or the housing 11 can be fixedly connected with a vehicle body structure or the like. The housing 11 can be formed with a mounting hole 111 penetratingly arranged in a first direction, at least a part of the transmission member 12 can be penetratingly arranged in the mounting hole 111, and the transmission member 12 can rotate relative to the housing 11, the steering wheel body 13 can be formed with an extension member 131 extending towards the mounting hole 111, and at least a part of the extension member 131 can be accommodated in the mounting hole 111, the extension member 131 can be connected with the transmission member 12, and optionally, the extension member 131 and the transmission member 12 can be detachably connected through clamping or insertion, when the transmission member 12 rotates relative to the housing 11, the transmission member 12 can drive the extension member 131 to synchronously rotate, and further drive the steering wheel body 13 to rotate, so that the steering wheel body 13 is rotated to the inside of the dashboard, and the steering wheel body 13 is retracted, thereby reducing the space occupied by the steering wheel body 13 in the cab.

[0039] Further, at least a part of the inner wall of the mounting hole 111 can be formed with a first guide portion 1111, and the outer peripheral wall of the extension member 131 can be provided with a second guide portion 1311, and the second guide portion 1311 can be selectively matched with the first guide portion 1111 to drive the extension member 131 to move in the first direction when the extension member 131 rotates relative to the housing 11. It can be understood that the second guide portion 1311 can be matched with the first guide portion 1111 to drive the extension member 131 to rotate relative to the housing 11 when the transmission member 12 rotates relative to the housing 11, and the first guide portion 1111 can be driven to rotate when the extension member 131 rotates, and the second guide portion 1311 can guide the first guide portion 1111 to move along the second guide portion 1311, thereby realizing the movement of the extension member 131 in the first direction, and further changing the size of the steering wheel body 13 in the first direction, reducing the space occupied by the steering wheel body 13, and meeting the demand of the driver and the passenger for the space in the cab.

[0040] In short, the steering wheel assembly 10 of the embodiment of the present application can realize the synchronous rotation of the steering wheel body 13 when the transmission member 12 rotates by rotatably arranging the transmission member 12 on the housing 11, and connecting the transmission member 12 with the extension member 131 of the steering wheel body 13, and the first guide portion 1111 is formed on the housing 11, and the second guide portion 1311 is formed on the extension member 131, and the first guide portion 1111 and the second guide portion 1311 can be matched to drive the extension member 131 to move in the first direction when the extension member 131 rotates relative to the housing 11, thereby changing the size of the steering wheel body 13 in the first direction, and further reducing the space occupied by the steering wheel body 13, and meeting the demand of the driver and the passenger for the space.

[0041] As shown in Figure 2 and Figure 7 In some embodiments of the present application, the housing 11 can be formed with a mounting groove 112, which can be recessed towards the inside of the housing 11. The steering wheel assembly 10 can further include a driving member 14, which can be arranged in the mounting groove 112, and the driving member 14 can be formed with a driving portion 141, which can be used to drive the transmission member 12 to rotate relative to the housing 11. In some embodiments, the driving member 14 can be configured as a driving motor, and the driving portion 141 can be an output shaft of the driving motor. The driving portion 141 drives the transmission member 12 to rotate relative to the housing 11, and the transmission member 12 drives the extension member 131 to rotate synchronously, thereby realizing the rotation of the steering wheel body 13 relative to the housing 11.

[0042] Further, as shown in Figure 5 The transmission member 12 can be formed with a transmission portion 121, which can be in transmission connection with the driving portion 141. Optionally, the driving portion 141 can be configured as one of a worm gear and a worm, and the transmission portion 121 can be configured as the other one of the worm gear and the worm. The worm gear and the worm are in transmission connection to realize the transmission of power, that is, the driving portion 141 drives the transmission portion 121 to rotate. The worm gear and the worm can improve the stability of power transmission between the transmission portion 121 and the driving portion 141, and have good self-locking function. In some embodiments, the transmission portion 121 can be located at the center point position of the transmission member 12 to ensure that both ends of the transmission member 12 along the first direction can be uniformly stressed.

[0043] As shown in Figure 2 and Figure 7 In some embodiments of the present application, the housing 11 can be formed with a relief portion 113, which can be used to avoid the transmission portion 121, and at least part of the driving portion 141 can extend into the relief portion 113. By arranging the relief portion 113 on the housing 11, the overall structure can be more compact, which is beneficial to the miniaturization design of the steering wheel assembly 10, and reduces the occupied space of the driving member 14.

[0044] As shown in Figure 6As shown, in some embodiments of this application, a receiving groove 1312 may be formed in the extension member 131. The receiving groove 1312 can be used to receive the transmission member 12. A first mating part 1313 may be formed on the inner wall of the receiving groove 1312. At least a portion of the outer peripheral wall of the transmission member 12 may be formed with a second mating part 122. The second mating part 122 can cooperate with the first mating part 1313. Optionally, the first mating part 1313 and the second mating part 122 can abut against each other along the circumference of the receiving groove 1312, thereby achieving circumferential positioning of the first mating part 1313 and the second mating part 122. Therefore, when the transmission member 12 rotates, the extension member 131 can be driven to rotate synchronously through the cooperation between the first mating part 1313 and the second mating part 122.

[0045] like Figure 3 As shown, in some embodiments of this application, the first guide portion 1111 can be spirally arranged on at least a portion of the inner wall of the mounting hole 111 along the first direction. It is understood that the first guide portion 1111 can be spirally arranged. Therefore, when the drive member 14 rotates, since the first guide portion 1111 cooperates with the second guide portion 1311, the second guide portion 1311 needs to move along the first guide portion 1111, thereby realizing the movement of the drive member 14 in the first direction.

[0046] In some embodiments of this application, the outer surface of the transmission member 12 may be formed with a first sliding portion, and the inner wall of the receiving groove 1312 may be formed with a second sliding portion. The second sliding portion may slide in cooperation with the first sliding portion. Optionally, the first sliding portion may be constructed as one of a slider and a groove, and the second sliding portion may be constructed as the other of a slider and a groove. Through the cooperation of the slider and the groove, the outer surface of the slider abuts against the inner surface of the groove, thereby causing the driving member 14 to slide along the extension direction of the transmission member 12, thereby improving the stability of the cooperation between the driving member 14 and the transmission member 12.

[0047] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the first mating part 1313 can be constructed as one of a slider and a groove, and the second mating part 122 can be constructed as the other of a slider and a groove. It is understood that the slider and the groove can abut in the circumferential direction to achieve the circumferential positioning of the first mating part 1313 and the second mating part 122. When the transmission member 12 rotates, it can drive the extension member 131 to rotate synchronously through the first mating part 1313 and the second mating part 122. The outer surface of the slider abuts against the inner surface of the groove, thereby causing the driving member 14 to slide along the extension direction of the transmission member 12.

[0048] like Figure 1 and Figure 2As shown, in some embodiments of the present application, the steering wheel body 13 can include a first handle 132 and a second handle 133, both of which are formed with an extension 131 extending towards each other, both of which can be connected with both ends of the transmission member 12 in the first direction, further, the second guide part 1311 can selectively cooperate with the first guide part 1111, so that the first handle 132 and the second handle 133 can drive the first handle 132 and the second handle 133 to move in the first direction towards each other or away from each other when rotating relative to the housing 11, thereby realizing the contraction and expansion of the steering wheel body 13. The bottom of the first handle 132 and the bottom of the second handle 133 are spaced apart by a certain distance, thereby providing a certain space for the contraction of the steering wheel body 13, in specific embodiments, the outer side of the first handle 132 and the second handle 133 can be the handle of the steering wheel body 13.
