Air generator shock absorption device on steering wheel

Abstract

The invention provides an air generator shock absorption device on a steering wheel and belongs to the technical field of automobile accessories. The air generator shock absorption device comprises a support wheel and a buffer assembly. An air generator is connected onto the buffer assembly made of a rubber material. When head-on collision of a vehicle occurs, the buffer assembly made of the rubber material in an air bag restraint module can effectively buffer recoil force produced by the detonated air generator, namely the contact time of an air bag and a person is prolonged, the buffer time of a safety belt is prolonged, inertia impact of the person is reduced to some extent, impact force between the person and the air bag is reduced, and injury level is reduced. In addition, due to the fact that the air generator is connected onto an elastic connecting column of the buffer assembly, the air generator shock absorption device has certain shaking capacity. When jolt shake produced by the whole vehicle in running is transmitted to the steering wheel, the steering wheel can transmit agglomerated energy to the air generator through the buffer assembly, the air generator and the elastic connecting column shake, the shaking degree of the steering wheel is reduced, noise is reduced, and driving comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a shock absorber for a gas generator on a steering wheel. Background technique [0002] As we all know, the gas generator installed in the steering wheel of the car belongs to the airbag system module on the steering wheel of the car. The airbag can play a buffer role when the vehicle collides, thereby reducing the damage caused by the collision to the driver in the car. With the vigorous construction of expressways and the improvement of car driving performance, the speed of cars is getting faster and faster, especially due to the rapid increase in car ownership, traffic is becoming more and more congested, making accidents more frequent, in order to reduce car accidents Due to the damage to the driver caused by the huge inertial force during the frontal collision, the car is generally equipped with an airbag system in the center of the steering wheel at the front of the driv...

AI Technical Summary

Problems solved by technology

[0003] The airbag module in the existing steering wheel is mainly composed of an airbag, a gas generator and an igniter. The gas generator is directly fixed on the airbag bracket with special bolts, and the airbag bracket is fixed in the steering wheel. Vibration and noise reduction has a certain impact, and it cannot reduce the vibration of the steering wheel; in addition, in the event of a traffic accident, it cannot alleviate the large recoil force brought by the detonation of the airbag gas generator, which will cause certain impact and damage to the vehicle
