[0041] In this embodiment, the shock absorption component 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 component is installed at the middle position of the steering wheel skeleton 10. The shock absorption component includes a connecting portion, a damping element 30 and an axial connecting member 40. Among them, the connecting portion is arranged on the 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.

The sleeve holes of the connecting sleeves 204 are first through holes 202. The second connecting structure 201 is provided on the inner peripheral wall of the sleeve holes forming the connecting sleeves 204. In one example, three connecting sleeves 204 are provided and are distributed at intervals on the connecting support frame 203.
[0043] The damping element 30 is correspondingly arranged with the connecting portion. A second through hole 301 is provided at the center of the damping element 30.

In one example, the damping element 30 is made of an elastic material.
[0044] Specifically, the damping element 30 includes an axially arranged connecting cylinder 304 and a supporting disc 305. Among them, the supporting disc 305 is located at the lower part of the damping element 30 and forms the lower structure of the damping element 30. The upper end surface of the supporting disc 305 is connected to the lower end surface of the connecting portion. The supporting disc 305 is mounted in the mounting connection groove 101 provided on the steering wheel skeleton 10. The first connecting structure 302 is provided at the upper end position of the connecting cylinder 304.

Specifically, in one structural setting, the positioning groove is arranged on the bottom radial end face of the connecting cylinder 304, and correspondingly, the positioning protrusion is arranged on the upper radial end face of the supporting disc 305, and the connecting cylinder 304 and the supporting disc 305 are connected to each other by the positioning protrusion being clamped in the positioning groove. Further, it should be supplemented that in order to improve the stability of the positioning connection, and based on the circular structure of the connecting cylinder 304 and the supporting disc 305, the number of positioning grooves is set to multiple, and the multiple positioning grooves are distributed at intervals along the circumferential direction on the bottom radial end face of the connecting cylinder 304. In the 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 the positioning protrusions is set to be multiple, and the multiple positioning protrusions are distributed at intervals along the circumferential direction on the upper radial end surface of the support disk 305 and are arranged one-to-one correspondingly to the positioning grooves.

In the preferred example, the number of the positioning protrusions is set to be at least three, and the angle formed by every two adjacent positioning protrusions is 120 degrees. Correspondingly, the number of the positioning grooves is set to be multiple, and the multiple positioning grooves are distributed at intervals along the circumferential direction on the upper radial end face of the supporting disc 305, and are arranged one by one with the positioning protrusions. The connecting cylinder 304 and the supporting disc 305 are set as a non-integrated structure, which can facilitate the assembly connection of the connecting cylinder 304 and the supporting disc 305.
[0048] In this embodiment, based on the connection relationship between the connecting cylinder 304 and the supporting disk 305 , the second through hole 301 is axially penetrated and arranged in the center of the connecting cylinder 304 and the supporting disk 305 .
