DETAILED DESCRIPTION
[0035] The following will be described in detail below with reference to the accompanying drawings. Figures 1-4 The present application is further described in detail.
[0036] The present application discloses a steering wheel horn pressing structure.
[0037] Reference will be made to Figure 1 and Figure 2 A steering wheel horn pressing structure includes a steering wheel framework 1, a horn support 2, and a buffer assembly 3. The horn support 2 includes a support sheet metal 21 and a support plastic body 22 that wraps the support sheet metal 21. Three mounting through holes 23 are formed circumferentially on the horn support 2 for mounting the buffer assembly 3, and the three mounting through holes 23 are arranged in a triangular shape.
[0038] Reference will be made to Figure 2 and Figure 3 The buffer assembly 3 includes a connecting rivet 31, a buffer spring 32, a buffer piece 33, and a limiting washer 34. The connecting rivet 31 includes a rivet head and a rivet column inserted into the mounting through hole 23, and the rivet column includes a threaded portion 311 that threadedly cooperates with the steering wheel framework 1 and a sliding portion 312 that slidingly cooperates with the buffer piece 33. The outer diameter of the sliding portion 312 is larger than that of the threaded portion 311, and a limiting gap 313 is formed between the sliding portion 312 and the steering wheel framework 1.
[0039] The limiting washer 34 and the threaded portion 311 are sleeved and cooperated, and are arranged in the limiting gap 313. The two ends of the buffer spring 32 abut against the buffer piece 33 and the limiting washer 34, respectively. When a user presses the horn support 2, the horn support 2 and the buffer piece 33 move synchronously towards the steering wheel framework 1.
[0040] The buffer piece 33 includes a buffer ring 331 and a guide sleeve 332, and the buffer ring 331 is clamped and fixed with the horn support 2. In this embodiment, the buffer ring 331 is made of rubber, and the outer side wall of the buffer ring 331 is provided with a clamping ring groove 3311 that clamps and cooperates with the mounting through hole 23.
[0041] The buffer ring 331 is formed with a first abutting ring 3312 and a second abutting ring 3313 on both sides of the clamping ring groove 3311 in the axial direction. The first abutting ring 3312 and the second abutting ring 3313 abut against the opposite end faces of the horn support 2. The buffer ring 331 is provided with two material reducing grooves 3314 on the second abutting ring 3313, which are symmetrically arranged along the axis of the abutting ring, so as to facilitate the extrusion of the deformation buffer ring 331 by the assembly personnel and improve the assembly efficiency of the buffer ring 331 and the horn support 2.
[0042] The first abutting ring 3312 is provided with an anti-skid ratchet surface 3315 away from the end face of the horn support 2. The ratchet extending direction of the anti-skid ratchet surface 3315 is opposite to the tightening direction of the connecting rivet 31.

The first limiting arc part 3316 and the second limiting arc part 3322 are provided with guide inclined surfaces 3323. By means of the guide inclined surfaces 3323, when the guide sleeve 332 is inserted, the two guide inclined surfaces 3323 abut against each other, so that the two limiting arc parts are extruded and deformed, and the clamping efficiency is improved.
[0044] The inner side wall of the buffer ring 331 is circumferentially spaced apart and provided with a pressing protrusion 3317 abutting the insertion part 3321, which is an arc protrusion towards the central axis of the buffer ring 331, for improving the clamping stability of the guide sleeve 332 and the buffer ring 331.
[0045] The side of the guide sleeve 332 away from the buffer ring 331 has a arrangement groove 3324 for arranging one end of the buffer spring 32. The arrangement groove 3324 is an annular groove, and the guide sleeve 332 is circumferentially spaced apart and provided with a plurality of limiting protrusions 3325 on the inner wall of the arrangement groove 3324. One end of the buffer spring 32 can be limited and clamped in the limiting protrusion 3325.
[0046] The assembling process of the steering wheel horn pressing structure is as follows: first, the horn support 2 is subjected to sheet metal plastic packaging, then the buffer ring 331 is installed, and the second abutting ring 3313 is inserted into the mounting hole 23 in alignment; then the guide sleeve 332 is inserted into the buffer ring 331 from one side of the second abutting ring 3313, and the fixing of the guide sleeve 332 and the buffer ring 331 is realized through the first limiting arc part 3316 and the second limiting arc part 3322; then the connecting rivet 31 is inserted from one side of the first abutting ring 3312, one end of the buffer spring 32 is limited and clamped in the arrangement groove 3324, and the limiting washer 34 is sleeved on the threaded part 311; finally, the threaded part 311 and the steering wheel skeleton 1 are screwed.
