Connecting structure of automobile steering wheel and driver airbag

Abstract

The invention discloses a connecting structure of an automobile steering wheel and a driver airbag. The connecting structure comprises a steering wheel framework and an airbag shell for mounting the driver airbag, and is characterized in that a plurality of positioning holes are formed in the periphery of a mounting hole in the steering wheel framework, and a plurality of elastic positioning columns are arranged on the bottom surface of the airbag shell; the elastic positioning columns are inserted into the positioning holes in a one-to-one correspondence manner; three bosses are arranged on the steering wheel framework and located in the periphery of an installation hole of the steering wheel framework, notches are formed in the sides, corresponding to the installation hole, of the bossesrespectively, inserting holes communicated with the notches are formed in the bosses respectively, three clamping hooks are arranged on the bottom face of the air bag shell, and the clamping hooks are inserted into the corresponding inserting holes respectively and limited through U-shaped clamping springs. The middle part and the two ends of each U-shaped snap spring are respectively clamped into the notches and are clamped on the corresponding clamping hooks; and a plurality of pressure springs are clamped between the steering wheel framework and the bottom surface of the airbag shell. Theautomobile steering wheel system has the advantages that abnormal sounds caused by automobile body vibration can be effectively avoided, and the user driving experience is improved.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a connection structure between an automobile steering wheel and a driver's air bag. Background technique [0002] With the development of China's economy, cars have entered more and more families. Drivers' driving experience and riding experience are becoming more and more detailed, and they are increasingly pursuing higher quality. When the traditional steering wheel system of a car passes through uneven roads such as cobblestones and washboard roads, the car itself will vibrate with the road surface and be transmitted to the steering wheel system, causing the steering wheel system to vibrate violently. Collision at the positioning position will produce a crisp impact sound, which will cause the driver to feel uncomfortable and affect the judgment of other sounds in the car. Because the above problems are likely to cause customer dissatisfaction, the driving experience on bumpy...

Problems solved by technology

[0003] Generally, the traditional automobile steering wheel system can only reduce the relative vibration between the steering wheel and the driver’s airbag by increasing the spring force. Turn the horn switch, and the abnormal vibration cannot be completely solved
