[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] The following is for reference. Figures 1-8 The steering wheel assembly 10 according to an embodiment of the present application is described. The steering wheel assembly 10 includes a housing 11, a first transmission assembly 12, a second transmission assembly 13, and a steering wheel body 14.

[0042] The first transmission assembly 12 is rotatably mounted on the housing 11. The second transmission assembly 13 is movably mounted on the housing 11. The steering wheel body 14 has a first connecting end 141 and a second connecting end 142. The first connecting end 141 is drively connected to the first transmission assembly 12, and the second connecting end 142 is drively connected to the second transmission assembly 13. The first transmission assembly 12 is adapted to drive the steering wheel body 14 to rotate relative to the housing 11, and the second transmission assembly 13 is adapted to drive the steering wheel body 14 to retract.

[0043] Currently, when a vehicle enters autonomous driving mode, the steering wheel occupies a certain amount of interior space. This not only limits the diversity of vehicle interior design but also makes it difficult to meet passengers' needs for a spacious and flexible riding environment. However, existing steering wheels do not have a folding / retracting function. Therefore, how to effectively reduce the space occupied by the steering wheel in autonomous driving mode is a technical problem.

[0044] In response, this application proposes a steering wheel assembly 10 that can reduce the space occupied by the steering wheel body 14 and meet the space requirements of drivers and passengers.

[0045] like Figure 1 and Figure 2 As shown, specifically, the steering wheel assembly 10 may include a housing 11, a transmission assembly, and a steering wheel body 14. The housing 11 may be fixedly connected to the vehicle's instrument panel assembly, or the housing 11 may be fixedly connected to a structure such as the vehicle body. The transmission assembly may include a first transmission assembly 12 and a second transmission assembly 13. The first transmission assembly 12 is rotatably mounted on the housing 11, meaning it can rotate relative to the housing 11. The second transmission assembly 13 is movably mounted on the housing 11, meaning it can move relative to the housing 11. The steering wheel body 14 has a first connecting end 141 and a second connecting end 142. The first connecting end 141 can be drive-connected to the first transmission assembly 12, and the second connecting end 142 can be drive-connected to the second transmission assembly 13.

[0046] In some embodiments, housing 11 may include an upper housing 111 and a lower housing 112. The lower housing 112 may be located at the bottom end of the upper housing 111 and connected to the upper housing 111. A first transmission assembly 12 is rotatably disposed at the upper housing 111, and a second transmission assembly 13 is movably disposed at the lower housing 112.

[0047] Furthermore, such as Figure 3As shown, the first transmission component 12 can drive the steering wheel body 14 to rotate relative to the housing 11, thereby rotating the steering wheel body 14 into the dashboard, thus reducing the space occupied by the steering wheel body 14 in the driver's cab. The second transmission component 13 can drive the steering wheel body 14 to retract, thereby reducing the size of the steering wheel body 14 and thus reducing the space occupied by the steering wheel body 14. It can be understood that the first transmission component 12 and the second transmission component 13 can be operated independently to ensure that the steering wheel assembly 10 can drive the steering wheel body 14 to rotate or retract, or rotate and retract simultaneously, improving the flexibility of the steering wheel assembly 10. By setting the first transmission component 12 and the second transmission component 13, the rotation and retraction of the steering wheel assembly 10 can be realized, reducing the space occupied by the steering wheel body 14 and meeting the user's needs for cab space.

[0048] In short, the steering wheel assembly 10 of this application embodiment is provided with a first transmission component 12 and a second transmission component 13. The first transmission component 12 and the second transmission component 13 are disposed on the housing 11 and are connected to the steering wheel body 14. The first transmission component 12 can rotate relative to the housing 11 to drive the steering wheel body 14 to rotate, and the second transmission component 13 can move relative to the housing 11 to drive the steering wheel body 14 to retract, thereby reducing the space occupied by the steering wheel body 14 and meeting the space requirements of the driver and passengers.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the first transmission assembly 12 may include a first transmission shaft 121 and a first transmission wheel 122. The first transmission shaft 121 passes through the housing 11. Optionally, the housing 11 may have a plurality of first through holes 114 arranged axially through it. The first transmission shaft 121 may be received within the plurality of first through holes 114, thereby realizing the axial connection between the first transmission shaft 121 and the housing 11. Fixed ends 1211 may be formed at both ends of the first transmission shaft 121 along the axial direction. The fixed ends 1211 may cooperate with the first connecting end 141. In some embodiments, the fixed ends 1211 may cooperate with the first connecting end 141. 41 is snap-fit ​​or plug-in connected. When the fixed end 1211 rotates, it can drive the first connecting end 141 to rotate synchronously, thereby realizing that the first transmission component 12 drives the steering wheel body 14 to rotate. Furthermore, the cross section of the fixed end 1211 along the perpendicular axis can be polygonal. It can be understood that the fixed end 1211 can be constructed as a polygonal columnar structure, and the first connecting end 141 can be constructed as a polygonal hole. At least part of the fixed end 1211 is housed in the first connecting end 141 and snap-fits with the first connecting end 141, thereby realizing that the first transmission shaft 121 drives the steering wheel body 14 to rotate synchronously by rotating relative to the housing 11.

[0050] The first drive wheel 122 can be disposed on the housing 11. Optionally, the housing 11 can be formed with a second through hole 115 extending axially. The first drive wheel 122 can be received within the second through hole 115. In some embodiments, the first drive wheel 122 can be formed with a flange 1221, and the inner wall of the second through hole 115 can be formed with a groove. At least a portion of the flange 1221 can be received within the groove, thereby limiting the first drive wheel 122 axially. The first drive wheel 122 can be connected to the first drive shaft 121. In the transmission connection, the first transmission wheel 122 can selectively rotate relative to the housing 11, thereby driving the first transmission shaft 121 to rotate. The first transmission wheel 122 can be connected to a drive motor, and the output shaft of the drive motor can be connected to the first transmission wheel 122, for example, through a coupling, thereby driving the first transmission wheel 122 to rotate relative to the housing 11. The first transmission wheel 122 drives the first transmission shaft 121 to rotate, and the first transmission shaft 121 drives the steering wheel body 14 to rotate, thereby realizing the rotation of the steering wheel body 14 relative to the housing 11.

[0051] like Figure 2 , Figure 5 and Figure 8 As shown, in some embodiments of this application, a gear portion 1212 may be provided on the first transmission shaft 121. The gear portion 1212 may have meshing teeth 1213 formed on its outer circumferential direction. The meshing teeth 1213 may be connected to the first transmission wheel 122 for transmission. It is understood that the gear portion 1212 may be located at the center point of the first transmission shaft 121 so that the two sides of the first transmission shaft 121 are evenly stressed. The gear portion 1212 may be constructed as a circular gear, a sector gear, or a semi-circular gear.

[0052] like Figure 2 and Figure 4As shown, in some embodiments of this application, the second transmission assembly 13 may include a second transmission wheel 131 and a sliding member 132. The second transmission wheel 131 may be disposed on the housing 11, and the sliding member 132 may be pulsatorically connected to the second connecting end 142. A rack portion 13231 may be formed on the sliding member 132, and the rack portion 13231 may be pulsatorically connected to the second transmission wheel 131. The second transmission wheel 131 may selectively rotate relative to the housing 11 to drive the sliding member 132 to move. It is understood that the second transmission wheel 131 may rotate relative to the housing 11, and the second transmission wheel 131 meshes with the rack portion 13231 to drive the sliding member 132 to move. The second transmission wheel 131 may be driven by a drive motor. Furthermore, the slider 132 is connected to the second connecting end 142, and the number of sliders 132 can be two. When the two sliders 132 move toward each other, the size of the steering wheel body 14 can be changed, that is, the size of the steering wheel body 14 along the axial direction of the first drive shaft 121 is reduced, thereby realizing the shrinkage of the steering wheel body 14.

[0053] like Figure 2 and Figure 4 As shown, in some embodiments of this application, the sliding member 132 may include a first sliding portion 1321, a connecting portion 1322, and a transmission portion 1323. The first sliding portion 1321 is movably disposed on the housing 11. The connecting portion 1322 may be disposed on the first sliding portion 1321, and a pawl 13221 may be formed at the free end of the connecting portion 1322. The pawl 13221 may be driveably connected to the second connecting end 142. It is understood that the pawl 13221 may be radially limited with the second connecting end 142, and the pawl 13221 may drive the second connecting end 142 to move axially by being driveably connected to the second connecting end 142. The transmission portion 1323 may be disposed on the first sliding portion 1321, and a rack portion 13231 may be formed on the transmission portion 1323. The rack portion 13231 may be power-connected to the second transmission wheel 131. In a specific embodiment, the rack portion 13231 and the second transmission wheel 131 are connected by a gear and rack.

[0054] like Figure 2 As shown, in some embodiments of this application, a second sliding portion 113 may be formed on the housing 11, and the first sliding portion 1321 may slide along the second sliding portion 113. Optionally, the first sliding portion 1321 may be configured as one of a slider and a guide rail, and the second sliding portion 113 may be configured as the other of a slider and a guide rail. A groove may be formed on the slider, and at least a portion of the guide rail may be accommodated in the groove. The outer surface of the guide rail may abut against the inner wall of the groove, thereby enabling the slider to slide along the extension direction of the guide rail when sliding, thereby providing guidance for the sliding of the slider.

[0055] like Figure 2 and Figure 7 As shown, in some embodiments of this application, an extension 143 may be formed on the steering wheel body 14. The extension 143 may extend toward the first drive shaft 121. A first connecting end 141 may be formed at the free end of the extension 143. A second connecting end 142 may be formed along the circumferential sidewall of the extension 143. It is understood that the steering wheel body 14 can rotate and retract through the extension 143. The extension 143 may be disposed on the inner side of the steering wheel body 14, thereby avoiding the extension 143 from affecting the driver's normal operation of the steering wheel body 14.

[0056] like Figure 2 and Figure 7 As shown, in some embodiments of this application, the steering wheel body 14 may include a first handle 144, a second handle 145, and a connecting block 146. Both the first handle 144 and the second handle 145 have extensions 143. The connecting block 146 may be disposed between the first handle 144 and the second handle 145. One end of the connecting block 146 may be received in the first handle 144, and the other end of the connecting block 146 may be received in the second handle 145. The first handle 144 and the second handle 145 may selectively move toward each other to cover the connecting block 146, thereby enabling the steering wheel body 14 to retract. Optionally, the outer wall of the connecting block 146 may have a protrusion, and the interior of the first handle 144 and the second handle 145 may have a groove. The protrusion may engage with the groove, and the outer wall of the protrusion may fit against the inner wall of the groove to achieve the guiding function of the connecting block 146 and ensure the stability of the steering wheel body 14 when retracted.

[0057] like Figure 2 and Figure 7As shown, in some embodiments of this application, a first receiving groove 1441 is formed on the first handle 144 and the second handle 145. Optionally, the inner wall of the first receiving groove 1441 may be formed with a recess. The first receiving groove 1441 can be used to receive the connecting block 146. It can be understood that one end of the connecting block 146 can be received in the first receiving groove 1441 of the first handle 144, and the other end of the connecting block 146 can be received in the first receiving groove 1441 of the second handle 145. The steering wheel body 14 may also include an elastic element 147, which can be received in a first receiving groove 1441. One end of the elastic element 147 can be connected to the inner wall of the first receiving groove 1441, and the other end of the elastic element 147 can abut against the connecting block 146. The bottom wall of the first receiving groove 1441 can form a limiting post 1442. The elastic element 147 can be sleeved on the outer wall of the limiting post 1442 to limit one end of the elastic element 147. In a specific embodiment, the elastic element 147 can be constructed as a spring. Optionally, a second receiving groove 1461 can be formed inside the connecting block 146. The other end of the elastic element 147 can be received in the second receiving groove 1461 inside the connecting block 146 and abut against the inner wall of the second receiving groove 1461 to limit the elastic element 147.

[0058] like Figure 1 and Figure 3 As shown, in one embodiment of this application, when the vehicle needs to retract and fold the steering wheel body 14, the drive motor drives the second transmission wheel 131 to rotate. Under the meshing action of the gear and rack, the two sliding members 132 can slide inward along the second sliding part 113. Under the action of the shaft connection, the first handle 144 and the second handle 145 can slide inward along the first transmission shaft 121 respectively. Under the action of the sliding contact and the elastic member 147, the first handle 144 and the second handle 145 can respectively enclose the connecting block 146 from both ends and compress the elastic member 147, thereby realizing the electric retraction action of the steering wheel body 14. The drive motor drives the first transmission wheel 122 to rotate. Under the meshing action of the gear, the first transmission shaft 121 rotates downward. Under the action of the sliding contact and the shaft connection, the first handle 144 and the second handle 145 rotate synchronously, thereby realizing the electric folding action.
