[0035] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0036] Reference below Figure 1-Figure 10 A steering wheel assembly 100 according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0037] Reference Figure 1-9 As shown, the steering wheel assembly 100 of the embodiment of the present invention includes: a first body 10 , a second body 20 and a driving assembly 30 .

[0038] The second body 20 is disposed below the first body 10 and the arc length of the second body 20 is smaller than that of the first body 10. Specifically, the outer ring of the circular steering wheel is divided into two parts, the first body 10 and the second body 20. The first body 10 is used to connect with the upper end of the steering column of the vehicle to manipulate the steering system. When the driver turns the first body 10, the vehicle can be steered. The second body 20 is located below the first body 10, that is, on the side closer to the driver. The arc length of the second body 20 is smaller than that of the first body 10, and the second body 20 can move up and down relative to the first body 10.

[0039] The driving assembly 30 is disposed on the first body 10 and is transmission-connected to the second body 20, so as to drive the second body 20 to move up and down relative to the first body 10. The driving assembly 30 may include a driving motor 31, which is connected to a vehicle body controller, and the vehicle body controller is used to store a control program and control the driving motor 31. After the vehicle body controller sends a control signal, the driving motor 31 drives the driving assembly 30 to drive the second body 20 to move up and down relative to the first body 10 after receiving the control signal.

[0040] The second body 20 has a retracted position and an extended position. When the second body 20 is in the extended position, the outer periphery of the first body 10 and the second body 20 forms a complete circle or ellipse. Specifically, the extended position of the second body 20 refers to the position where the outer periphery of the second body 20 and the first body 10 form a complete circle or ellipse steering wheel structure. At this time, the driver can turn the outer ring of the steering wheel to steer the vehicle. The retracted position of the second body 20 refers to the position after the second body 20 moves upward relative to the first body 10. At this time, the space in front of the driver's seat becomes larger due to the retraction of the second body 20, which can improve the comfort of the driver.

[0041] Therefore, by providing a driving component 30 and a second body 20 that can move up and down relative to the first body 10, when the driver gets on or off the vehicle or rests in the vehicle, the driving component 30 drives the second body 20 to a retracted position, thereby increasing the space in front of the driver's seat and improving the driver's comfort.

[0042] Reference Figure 2-5 As shown, the first body 10 includes: a first base 11, a first outer ring 12 and a first connecting arm 13, the first connecting arm 13 is connected between the first base 11 and the first outer ring 12, and the driving assembly 30 is arranged on the first base 11. Specifically, the first body 10 is connected to the vehicle steering system through the first base 11, so as to facilitate the transmission of the steering force of the driver turning the first body 10 to the steering mechanism of the vehicle. Among them, a first connecting hole is arranged at the center of the first base 11, and the first connecting hole is used to connect with the steering column of the vehicle. A second connecting hole is also arranged on the first base 11, and the second connecting hole is used to fix the driving assembly 30 and the first base 11. The connection method of the first base 11 and the driving assembly 30 can be a threaded connection.

[0043] Furthermore, both ends of the driving assembly 30 can be fixed on the first base 11 by two fixing straps.

[0044] The first outer ring 12 refers to the part surrounding the outer ring of the first base 11, which is held by the driver, and functional buttons can also be set on it. The first connecting arm 13 is connected between the first base 11 and the first outer ring 12, and can transmit the force received by the first outer ring 12 to the first base 11, and then transmit it to the steering system through the first base 11. At the same time, the first connecting arm 13 can also enhance the strength of the connection between the first base 11 and the first outer ring 12, thereby improving the durability of the steering wheel assembly 100.

[0045] In this embodiment, there are two first connecting arms 13 symmetrically arranged on the left and right sides of the first base 11 . In other embodiments, there may be three, four or more first connecting arms 13 .

[0046] And, the second body 20 includes: a second base 21, a second outer ring 22 and a second connecting arm 23, and the second connecting arm 23 is connected between the second base 21 and the second outer ring 22. Specifically, the second base 21 is fixedly connected to the first base 11, so as to fix the first body 10 and the second body 20. The second outer ring 22 refers to the part surrounding the outer ring of the second base 21, which is the part held by the driver, and the arc length of the second outer ring 22 is less than the arc length of the first outer ring 12. The second connecting arm 23 is connected between the second base 21 and the second outer ring 22. When the second body 20 is in the unfolded position, it is used to transfer the force received by the second outer ring 22 to the second base 21. The second base 21 is connected to the first base 11, and the received force is transferred to the steering system through the first base 11. At the same time, the second connecting arm 23 can also enhance the strength of the connection between the second base 21 and the second outer ring 22, thereby improving the durability of the steering wheel assembly 100.

[0047] Reference Figure 2-3 As shown, at least two mounting seats 111 are provided on one side of the first base 11, and a positioning groove 1111 extending in the up-down direction is provided on the mounting seat 111.

Since the first gear portion 411 and the second gear portion 412 are both provided on the transmission member 41, the first gear portion 411 can rotate with the rotation of the second gear portion 412. Therefore, the driving gear 32 is driven to rotate by the driving motor 31, and the positioning column 211 can move up and down, thereby realizing the up and down movement of the second body 20 relative to the first body 10. When the driver gets on or off the vehicle or takes a rest, the space occupied by the steering wheel assembly 100 is reduced, thereby increasing the comfort of the driver.

[0056] And, the process of the driving component 30 driving the second body 20 to move is controlled by the control system and can be operated by the driver.
