[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] Reference below Figure 1-Figure 5 The roller switch assembly 100 , the steering wheel and the vehicle according to the embodiment of the present invention are described.

[0032] The steering wheel of the embodiment of the utility model comprises a steering wheel body and a roller switch assembly 100 .

[0033] The steering wheel body is provided with a mounting groove.

[0034] The roller switch assembly 100 comprises a bracket 1, a rolling element 2, a roller 3 and an elastic element 4. The bracket 1 is arranged in a mounting groove of a steering wheel body.

[0035] The rolling element 2 includes a support shaft 21, a track body 22 and a rotating transmission element 23. The support shaft 21 is rotatably disposed on the bracket 1. Each of the track body 22 and the rotating transmission element 23 is disposed on the support shaft 21 and is axially (eg Figure 1 and Figure 2 The roller 3 is sleeved on the support shaft 21 and is located between the track body 22 and the rotating transmission member 23. A portion of the roller 3 is located outside the mounting groove. The elastic member 4 is provided on the bracket 1, and the elastic member 4 abuts against the track body 22. The elastic member 4 abuts against the track body 22 to form a certain resistance to the rotation of the track body 22, providing a mechanical rolling feel for the person rotating the roller 3.

[0036] In the roller switch assembly 100 of the embodiment of the utility model, in the axial direction of the support shaft 21, the roller 3 is located between the track body 22 and the rotating transmission member 23, so the track body 22 and the rotating transmission member 23 are separated by the roller 3, and the rotating transmission member 23 and the connection between the rotating transmission member 23 and the downstream component will not be affected by the track body 22 and the downstream component connected to the track body 22, so that no interference occurs between the downstream connection component of the track body 22 and the downstream connection component of the rotating transmission member 23. In addition, since the track body 22 is located on the side of the roller 3 away from the rotating transmission member 23 (see Figure 1, the track body 22 is located on the left side of the roller 3), the downstream components that need to be connected to the track body 22 can use the space located on the side of the roller 3 away from the rotating transmission member 23 to extend in the direction away from the rotating transmission member 23, thereby reducing the space occupied by the support shaft 21 in its axial direction, reducing the requirement for the length of the support shaft 21, thereby reducing the axial size of the support shaft 21, reducing the axial size of the roller switch assembly 100 on the support shaft 21, and reducing the space occupied by the roller switch assembly 100 in the mounting groove.

[0037] Therefore, in the roller switch assembly 100 of the embodiment of the utility model, the roller 3 is located between the track body 22 and the rotating transmission member 23, which can ensure that the downstream connecting component of the track body 22 is separated from the roller 3 and does not interfere with each other, and ensure that the downstream connecting component of the track body 22 is separated from the rotating transmission member 23 and the downstream connecting component of the rotating transmission member 23 are separated from each other and do not interfere with each other, thereby reducing the axial size of the roller switch assembly 100 in the support shaft 21 and reducing the space occupied by the roller switch assembly 100 in the mounting groove of the steering wheel body.

[0038] In order to make the solution of the present application easier to understand, the axial direction and the left-right direction of the support shaft 21 are used as examples for explanation. Figures 1 to 3 and Figure 5 shown.

[0039] The roller switch assembly 100 of the embodiment of the utility model comprises a bracket 1, a rolling member 2, a roller 3 and an elastic member 4. The rolling member 2 comprises a support shaft 21, a track body 22 and a rotating transmission member 23, the support shaft 21 is rotatably arranged on the bracket 1, each of the track body 22 and the rotating transmission member 23 is arranged on the support shaft 21 and arranged at intervals in the axial direction of the support shaft 21, and the roller 3 is sleeved on the support shaft 21 and located between the track body 22 and the rotating transmission member 23.

[0040] like Figure 1 As shown, the bracket 1 includes a first support portion 11, a second support portion 12 and a connecting portion 13. The first support portion 11 is connected to the one end of the support shaft 21, the second support portion 12 is connected to the other end of the support shaft 21, and the connecting portion 13 is connected to the first support portion 11 and the second support portion 12 at both ends in the axial direction of the support shaft 21, respectively. The connecting portion 13 is an arc-shaped shell, and the roller 3 is located in the arc-shaped shell. The outer side surface of the connecting portion 13 of the arc-shaped shell is an arc-shaped surface. Compared with the square bracket used in the related art, it occupies less space, can further reduce the space occupied by the roller switch assembly 100 in the mounting groove of the steering wheel body, and can make room for a part of the space between the first support portion 11 and the second support portion 12 to facilitate the layout and arrangement of other components in the mounting groove.

[0041] The bracket 1 further includes a reinforcing rib 14, which is disposed on the connecting portion 13. Thus, the reinforcing rib 14 increases the strength of the connecting portion 13, thereby increasing the strength of the bracket 1, which is beneficial to improving the reliability of the roller switch assembly 100.

[0042] The bracket 1 has a shoulder 111 at one end adjacent to the elastic member 4. Figure 1 The first support portion 11 has a shoulder 111, and the shoulder 111 has two shoulders 111, and the two shoulders 111 are respectively located on both sides of the support shaft 21. The elastic member 4 has a buckling portion 42, and the buckling portion 42 is buckled on the shoulder 111. The buckling connection between the buckling portion 42 and the shoulder 111 is simple, which ensures that there is a certain contact area between the elastic member 4 and the bracket 1, ensures the stability of the connection between the elastic member 4 and the bracket 1, and further improves the reliability of the roller switch assembly 100.

[0043] In some embodiments, the elastic member 4 further has a connecting plate portion 43, the connecting plate portion 43 is spaced apart from the support shaft 21, one end (upper end) of the connecting plate portion 43 adjacent to the support shaft 21 is connected to the buckle portion 42, the connecting plate portion 43 is provided with one of a groove 431 or a protrusion, the bracket 1 is provided with the other of the groove 431 or the protrusion, and the protrusion fits in the groove 431. The fit of the protrusion and the groove 431 not only further increases the contact area between the elastic member 4 and the bracket 1, but also can position the connection between the elastic member 4 and the bracket 1, improve the convenience of positioning the elastic member 4 and the bracket 1, ensure the relative position relationship and abutment degree between the elastic portion 41 and the track body 22, and further improve the reliability of the roller switch assembly 100.

[0044] The connecting plate portion 43 of the roller switch assembly 100 of the present embodiment is provided with a groove 431 , and the first supporting end of the bracket 1 is provided with a protrusion (not shown in the figure).

[0045] The elastic member 4 has an elastic portion 41 . The elastic portion 41 is connected to the connecting plate portion 43 . The elastic portion 41 abuts against the track body 22 .

[0046] The elastic member 4 of the present embodiment is a stamped part. After the elastic member 4 is stamped, the elastic member 4 and the bracket 1 are integrally formed by insert injection molding.

[0047] In some embodiments, the support shaft 21, the track body 22 and the rotating transmission member 23 are an integrated structure. Therefore, there is no need to set a connection structure between each of the track body 22 and the rotating transmission member 23 and the support shaft 21, which reduces the number of parts of the roller switch assembly 100, reduces the size link of the motion transmission from the roller 3 to the track body 22, reduces the size link of the motion transmission from the roller 3 to the rotating transmission member 23, ensures the consistency of the rotation of the roller 3, the track body 22 and the rotating transmission member 23, improves the consistency of the hand feeling of the operator operating the roller 3 to achieve switch adjustment, and further improves the reliability of the roller switch assembly 100 of the embodiment of the utility model.

[0048] For details, see Figure 3 The rotating transmission member 23 is a gear, and correspondingly, the downstream component connected to the rotating transmission member 23 is a gear.

[0049] See also Figure 3 The track body 22 is located at the left end of the support shaft 21 , and the rotating transmission member 23 is located at the right end of the support shaft 21 .

[0050] In some embodiments, see Figures 3 to 5 The support shaft 21 includes a shaft body 211 and an assembly section 212. The track body 22 and the rotating transmission member 23 are arranged on the shaft body 211. The assembly section 212 is sleeved on the shaft body 211. The assembly section 212 is adjacent to the track body 22. The diameter of the assembly section 212 is larger than the outer diameter of the rotating transmission member 23. The outer diameter of the rotating transmission member 23 is larger than the diameter of the shaft body 211. The assembly section 212 is matched and connected with one end (left end) of the roller 3 in the axial direction thereof.

[0051] When assembling the rolling element 2 and the roller 3, the other end of the support shaft 21 provided with the rotating transmission element 23 is passed from the one end (left end) of the roller 3 to the other end (right end), and the assembly section 212 is matched with the one end of the roller 3. The assembly section 212 is matched with the one end of the roller 3 to connect the support shaft 21 with the roller 3, ensuring the transmission of motion between the roller 3 and the support shaft 21. The diameter of the assembly section 212 is larger than each of the diameter of the shaft body 211 and the outer diameter of the rotating transmission element 23, which not only facilitates the rotating transmission element 23 to pass through the roller 3, but also facilitates the matching connection between the assembly section 212 and the roller 3.

[0052] The fitting connection between the assembly section 212 and the roller 3 may be achieved by welding, interference fit or rib-groove fit.

[0053] In this embodiment, see Figures 3 to 5The assembly section 212 and the roller 3 are connected in a rib-groove matching manner. The assembly section 212 is provided with a first assembly groove 2121, and the roller 3 has a cavity. The roller 3 is provided with an assembly rib plate 31 in the cavity. The assembly rib plate 31 is matched in the first assembly groove 2121, and the projection surface of the rotating transmission member 23 along its axial direction on the end surface of the assembly section 212 is spaced from the assembly rib plate 31.

[0054] The projection surface of the rotating transmission member 23 along its axial direction on the end face of the assembly section 212 is spaced apart from the assembly rib 31, that is, the teeth of the rotating transmission member 23 are staggered from the assembly rib 31, so that when the rolling member 2 and the roller 3 are assembled, the rotating transmission member 23 and the assembly rib 31 do not interfere with each other, and the assembly rib 31 does not affect the rotating transmission member 23 passing through the roller 3, thereby ensuring the smoothness of the assembly.

[0055] The assembly section 212 and the roller 3 are connected through the cooperation of the first assembly groove 2121 and the assembly rib plate 31. Not only is the structure simple, but the cooperation of the first assembly groove 2121 and the assembly rib plate 31 can be completed during the assembly process as the rotating transmission member 23 passes through the roller 3. The assembly method is simple, which can save assembly steps and improve assembly efficiency.

[0056] Specifically, there are three assembly ribs 31 and three first assembly grooves 2121, and the three assembly ribs 31 are evenly spaced around the central axis of the roller 3. Correspondingly, the three first assembly grooves 2121 are evenly spaced around the shaft 211. The connection between the three assembly ribs 31 and the three assembly sections 212 is more stable, which can further improve the reliability of the roller switch assembly 100.

[0057] In some embodiments, the roller 3 includes a roller body 32 and a surface cover 33 connected to each other, an assembly rib 31 is provided in the roller body 32, a second assembly groove 332 is provided on the surface cover 33, and the assembly rib 31 is fitted in the second assembly groove 332. The assembly rib 31 is fitted in the second assembly groove 332 to connect the roller body 32 and the surface cover 33, and the connection structure is simple.

[0058] like Figures 3 to 5 As shown, the outer diameter of the track body 22 is larger than the diameter of the assembly section 212, and the track body 22 and the end (left end) of the roller 3 form a mutual limit. The track body 22 forms a limit on the left side of the roller 3 to prevent the roller 3 from sliding to the left.

[0059] The cover 33 has a hook 331, which is spaced apart from the assembly rib 31 in the circumferential direction of the support shaft 21, and has a first inclined surface and a first plane, wherein the distance between the first inclined surface and the shaft body 211 gradually shortens in the axial direction of the support shaft 21 in the direction close to the rotating transmission member 23, and the first plane faces the rotating transmission member 23. The support shaft 21 further includes a block 213, which is disposed on the shaft body 211, and the block 213 is opposite to the hook 331 in the axial direction of the support shaft 21, and has a second inclined surface 2131 and a second plane 2132, wherein the distance between the second inclined surface 2131 and the shaft body 211 gradually shortens in the axial direction of the support shaft 21 in the direction close to the rotating transmission member 23, and the second plane 2132 faces away from the rotating transmission member 23 and abuts against the first plane.

[0060] When assembling the rolling element 2 and the roller 3, in the process of the rotating transmission element 23 passing through the roller 3, since the block 213 on the shaft body 211 and the hook 331 on the surface cover 33 are opposite to each other in the axial direction of the support shaft 21, the second inclined surface 2131 of the block 213 gradually abuts against the first inclined surface of the hook 331, and the block 213 squeezes the hook 331. The block 213 pushes the hook 331 to deform so that the block 213 can move to the side (right side) of the hook 331 facing away from the track body 22, and then the second plane 2132 abuts against the first plane, so that mutual limitation is formed between the block 213 and the hook 331, and the block 213 on the support shaft 21 limits the right side of the hook 331 on the roller 3, thereby preventing the roller 3 from sliding to the right.

[0061] Therefore, after the rolling element 2 and the roller 3 are assembled, the track body 22 and the block 213 on the support shaft 21 form limits on the left and right sides of the roller 3 to prevent the roller 3 from sliding on the support shaft 21, further ensuring the stability and reliability of the roller switch assembly 100.

[0062] The steering wheel of the embodiment of the utility model reduces the axial size of the roller switch assembly 100 in the support shaft 21, and reduces the space occupied by the roller switch assembly 100 in the mounting groove of the steering wheel body, which is beneficial to the layout of other components inside the steering wheel, and is beneficial to reducing the overall size and weight of the steering wheel, and is beneficial to reducing the manufacturing cost of the steering wheel.

[0063] The vehicle of the embodiment of the utility model comprises a steering wheel.

[0064] The vehicle of the embodiment of the utility model has the advantages of reasonable internal layout of the steering wheel, small size and light weight.
