[0043] Next, the shock absorption component applied to the steering wheel provided in this application will be described below, which is hereinafter simply referred to as the shock absorption component.

[0044] Figure 1 is an exploded view of a shock absorption component provided by an embodiment of the present application. Figure 2 is a schematic structural diagram of a damping element provided by an embodiment of the present application. Figure 3 is a cross-sectional view of a shock absorption component provided by an embodiment of the present application.

[0045] In this embodiment, the shock absorption assembly is installed on the steering wheel skeleton 10. The steering wheel skeleton 10 is the main component of the steering wheel, and some related components in the steering wheel can be installed on the steering wheel skeleton 10. In one example, the shock absorption assembly is installed at the middle position of the steering wheel skeleton 10. The shock absorption assembly includes a connecting portion, a damping element 30, and an axial connecting member 40. Among them, the connecting portion is arranged on a fixed bracket 20 arranged opposite to the steering wheel skeleton 10. The connecting portion is provided with a first through hole 202, and a second connecting structure 201 is arranged on the inner peripheral surface of the first through hole 202.

[0046] In this embodiment, multiple connecting portions are provided. Specifically, the fixed bracket 20 includes a U-shaped connecting support frame 203 and multiple connecting sleeves 204. The connecting support frame 203 is provided with mounting slot holes at intervals. The connecting sleeves 204 are correspondingly installed in the mounting slot holes of the connecting support frame 203. The connecting sleeves 204 are the connecting portions of the fixed bracket 20. The sleeve holes of the connecting sleeves 204 are the first through holes 202, and the second connecting structure 201 is arranged on the inner peripheral wall of the sleeve holes constituting the connecting sleeves 204. In one example, three connecting sleeves 204 are provided and are spaced apart on the connecting support frame 203.

[0047] The damping element 30 is correspondingly arranged with the connecting portion. A second through hole 301 is arranged at the center of the damping element 30. The lower structure of the damping element 30 enables it to be installed in a mounting connection groove 101 provided on the steering wheel skeleton 10. A first connecting structure 302 corresponding to the second connecting structure 201 is arranged on the outer peripheral side of the upper portion of the damping element 30. The first connecting structure 302 and the second connecting structure 201 are connected to each other to realize the connection between the damping element 30 and the connecting portion. In one example, the damping element 30 is made of an elastic material.

[0048] Specifically, the damping element 30 includes an axially arranged connecting cylinder 303 and a support disc 304. Among them, the support disc 304 is located at the lower portion of the damping element 30 and forms the lower structure of the damping element 30. The upper end surface of the support disc 304 abuts against the lower end surface of the connecting portion. The support disc 304 is installed in the mounting connection groove 101 provided on the steering wheel skeleton 10. The first connecting structure 302 is arranged at the upper end position of the connecting cylinder 303. The connecting cylinder 303 is connected to the connecting portion through the first connecting structure 302.

[0049] In one example, the axially arranged connecting cylinder 303 and the support disc 304 are integrally formed, that is, the connecting cylinder 303 and the support disc 304 can be integrally formed by an integral stamping technique. Integrally forming the connecting cylinder 303 and the support disc 304 can increase the connection strength.

[0050] In another example, the axially arranged connecting cylinder 303 and the supporting disc 304 are connected by a positioning connection structure (not shown). The positioning connection structure includes a positioning groove and a positioning protrusion. Specifically, in one structural arrangement, the positioning groove is provided on the bottom radial end face of the connecting cylinder 303. Correspondingly, the positioning protrusion is provided on the upper radial end face of the supporting disc 304. The connecting cylinder 303 and the supporting disc 304 are connected to each other by fitting the positioning protrusion into the positioning groove. Further, it should be added that in order to improve the stability of the positioning connection and based on the fact that the connecting cylinder 303 and the supporting disc 304 are circular structures, the number of positioning grooves is set to be multiple, and the multiple positioning grooves are circumferentially spaced on the bottom radial end face of the connecting cylinder 303. In a preferred example, the number of positioning grooves is set to at least three, and the angle formed by every two adjacent positioning grooves is 120 degrees. Correspondingly, the number of positioning protrusions is set to be multiple, and the multiple positioning protrusions are circumferentially spaced on the upper radial end face of the supporting disc 304 and are arranged in one-to-one correspondence with the positioning grooves.

[0051] Alternatively, in another structural arrangement, the positioning groove is provided on the upper radial end face of the supporting disc 304. Correspondingly, the positioning protrusion is provided on the bottom radial end face of the connecting cylinder 303. The connecting cylinder 303 and the supporting disc 304 are connected to each other by fitting the positioning protrusion into the positioning groove. Similarly, in order to improve the stability of the positioning connection and based on the fact that the connecting cylinder 303 and the supporting disc 304 are circular structures, the number of positioning protrusions is set to be multiple, and the multiple positioning protrusions are circumferentially spaced on the bottom radial end face of the connecting cylinder 303. In a preferred example, the number of positioning protrusions is set to at least three, and the angle formed by every two adjacent positioning protrusions is 120 degrees. Correspondingly, the number of positioning grooves is set to be multiple, and the multiple positioning grooves are circumferentially spaced on the upper radial end face of the supporting disc 304 and are arranged in one-to-one correspondence with the positioning protrusions. Setting the connecting cylinder 303 and the supporting disc 304 as non-integrally formed structures facilitates the assembly connection of the connecting cylinder 303 and the supporting disc 304.

[0052] In this embodiment, based on the connection relationship between the connecting cylinder 303 and the supporting disc 304, the second through hole 301 is axially and penetratingly provided in the center of the connecting cylinder 303 and the supporting disc 304.

[0053] In this embodiment, the connecting cylinder 303 is sleeved inside the connecting sleeve 204, and the supporting disc 304 is arranged outside the connecting sleeve 204 and abuts against the installation connecting groove 101 provided on the steering wheel skeleton 10. In an example, in order to improve the stability of the sleeve connection between the connecting cylinder 303 and the connecting sleeve 204, the diameter dimension of the connecting cylinder 303 is the same as the diameter dimension of the sleeve hole of the connecting sleeve 204; alternatively, the connecting cylinder 303 and the sleeve hole of the connecting sleeve 204 are in interference fit. The diameter dimension of the supporting disc 304 is larger than the diameter dimension of the connecting cylinder 303.

[0054] In this embodiment, the first connection structure 302 includes an annular clamping groove, and the annular clamping groove is arranged on the outer peripheral surface of the damping element 30. Correspondingly, the second connection structure 201 includes an annular protrusion arranged on the inner peripheral surface of the first through-hole cylinder 202 of the connecting portion. The annular protrusion is clamped in the annular clamping groove to limit the freedom degree of the damping element 30 relative to the connecting portion in the axial direction. Further, corresponding to the specific structure of the damping element 30, the annular clamping groove is arranged on the outer peripheral surface of the connecting cylinder 303. When the connecting cylinder 303 is sleeved in the connecting sleeve 204, the connecting cylinder 303 is sleeved in the lower part of the connecting sleeve 204, and at the same time, the annular protrusion on the inner wall of the connecting sleeve 204 is clamped in the annular clamping groove on the outer peripheral surface of the connecting cylinder 303.

[0055] In an example, the first connection structure 302 includes an annular protrusion, and the annular protrusion is arranged on the outer peripheral surface of the damping element 30. Correspondingly, the second connection structure 201 includes an annular clamping groove arranged on the inner peripheral surface of the first through-hole cylinder 202 of the connecting portion. The annular protrusion is clamped in the annular clamping groove to limit the freedom degree of the damping element 30 relative to the connecting portion in the axial direction. Further, corresponding to the specific structure of the damping element 30, the annular protrusion is arranged on the outer peripheral surface of the connecting cylinder 303. When the connecting cylinder 303 is sleeved in the connecting sleeve 204, the connecting cylinder 303 is sleeved in the lower part of the connecting sleeve 204, and at the same time, the annular protrusion on the outer peripheral surface of the connecting cylinder 303 is clamped in the annular clamping groove on the inner wall of the connecting sleeve 204.

[0056] In this embodiment, the first connection structure 302 further includes a plurality of first card slots, which are arranged at intervals along the circumferential direction on the outer peripheral surface of the damping element 30, and the first card slots are located below the annular card slot. Correspondingly, the second connection structure 201 includes a plurality of first protrusions arranged at intervals along the circumferential direction on the lower end surface of the connection part. The first protrusions are clamped in the first card slots to limit the freedom degree of the damping element 30 relative to the connection part in the circumferential direction. Further, in combination with the specific structures of the damping element 30 and the connection part, the plurality of first card slots and the plurality of first protrusions are specifically arranged as follows: A plurality of the first card slots are provided on the upper end surface of the support disc 304, and the first card slots are arranged at intervals along the circumferential direction on the radial end surface of the support disc 304. Correspondingly, a plurality of first protrusions are provided on the lower end surface of the connection sleeve 204, and the plurality of first protrusions are arranged at intervals along the circumferential direction on the lower end surface of the connection sleeve 204. Each first protrusion corresponds to each first card slot, and each first protrusion is clamped with each first card slot to realize the connection between the upper end surface of the support disc 304 and the lower end surface of the connection sleeve 204. In this embodiment, the lower end surface of the connection sleeve 204 specifically refers to the circumferential end surface of the peripheral wall of the sleeve hole forming the connection sleeve 204.

[0057] In one example, the plurality of first card slots and the plurality of first protrusions can also be arranged as follows: A plurality of first protrusions are provided on the upper end surface of the support disc 304, and the first protrusions are arranged at intervals along the circumferential direction on the radial end surface of the support disc 304. Correspondingly, a plurality of first card slots are provided on the lower end surface of the connection sleeve 204, and the plurality of first card slots are arranged at intervals along the circumferential direction on the lower end surface of the connection sleeve 204. Each first protrusion corresponds to each first card slot, and each first protrusion is clamped with each first card slot to realize the connection between the upper end surface of the support disc 304 and the lower end surface of the connection sleeve 204. In this embodiment, the lower end surface of the connection sleeve 204 specifically refers to the circumferential end surface of the peripheral wall of the sleeve hole forming the connection sleeve 204.

[0058] In this embodiment, in order to improve the supporting ability of the damping element 30, a positioning support member 50 is further provided. The positioning support member 50 is sleeved in the second through hole 301 of the damping element 30 to form a positioning support for the damping element 30. A third through hole 503 is provided at the center of the positioning support member 50.

[0059] Specifically, the positioning support member 50 includes a lining sleeve. Among them, the lining sleeve includes a support column 501 and a defining shoulder 502 integrally formed. The support column 501 is sleeved in the second through hole 301 of the damping element 30, and a third through hole 503 is provided at the center of the support column 501. The defining shoulder 502 is connected to the upper part of the support column 501, and the defining shoulder 502 is in a ring structure. When the support column 501 is sleeved in the second through hole 301 of the damping element 30, the lower end surface of the defining shoulder 502 abuts against the radial end surface of the upper end of the connecting cylinder 303.

[0060] It should be noted that, in one example, the positioning support 50 can be injection molded or overmolded with the damping element 30. Of course, it can also be assembled separately as described in the above example.

[0061] After the damping element 30 is sleeved on the positioning support 50 and the connecting portion of the damping element 30 and the fixing bracket 20 is connected, the axial connecting member 40 passes through the first through hole 202 and the third through hole 503 and is connected to the shaft connection hole provided on the steering wheel skeleton 10, so as to realize the connection between the damping element 30 and the steering wheel skeleton 10. In this embodiment, the axial connecting member 40 includes a shaft position screw.

In addition, based on the reduction of vibration by the damping element 30, the stability of the connection of related structures is indirectly improved, and at the same time, the service life of related components of the steering wheel is improved. In addition, the connecting portion of the fixing bracket 20 is provided with a second connecting structure 201, which can be connected to the first connecting structure 302 on the outer peripheral side of the upper part of the damping element 30, so as to realize the connection between the damping element 30 and the connecting portion; and the axial connecting member 40 passes through the first through hole 202 and the second through hole 301 and is connected to the shaft connection hole provided on the steering wheel skeleton 10, so as to realize the connection between the damping element 30 and the steering wheel skeleton 10, that is, the fixing bracket 20, the damping element 30 and the steering wheel skeleton 10 are realized through the first connecting structure 302, the second connecting structure 201 and the axial connecting member 40.
