Problems solved by technology

The buffer mechanism uses a combination of spring and hook, which can effectively solve the problem of abnormal noise between the airbag module and the steering wheel due to vibration. However, since the spring and hook cannot limit the horizontal movement of the airbag module, it is easy to cause a gap in a long-term vibration environment. Uneven, thus can not completely solve the problem of abnormal sound between the airbag box and the airbag bracket

Abstract

The invention discloses a steering wheel air bag mounting structure. The structure comprises an air bag box body and an air bag mounting support, wherein the air bag box body is arranged on a steeringwheel framework body through the air bag mounting support, a plurality of positioning columns are arranged on the end surface, facing the air bag mounting support, of the air bag box body at intervals in the circumferential direction, a rubber pad is arranged on each positioning column, a positioning groove is formed in the position, corresponding to each positioning column, of the air bag mounting support, and during arranging, at least one part of the rubber pad on each positioning column of the air bag box body is embedded into each positioning groove of the air bag mounting support correspondingly. The invention also discloses a steering wheel comprising the steering wheel air bag mounting structure and an automobile comprising the steering wheel. According to the mounting structure,the steering wheel and the automobile, effective horizontal and vertical stress limits of the air bag box body can be formed.

Description

technical field [0001] The invention relates to the technical field of automobile steering wheels, in particular to a steering wheel airbag installation structure, a steering wheel and an automobile including the steering wheel airbag installation structure. Background technique [0002] The existing steering wheel air bag is directly installed on the steering wheel body through a mounting bracket. At present, when designing the position of the steering wheel airbag, the connection between the mounting bracket and the steering wheel bracket is usually fixed by a clip spring. However, after the simulation analysis of this structure, it is found that its local mode is low, and the steering wheel airbag module vibrates when the car is running, and the relative motion between the airbag module and the steering wheel produces noise. For this reason, Chinese invention patent CN208291164U discloses a steering wheel airbag buffer mechanism, including an airbag box body, an airbag b...
