AI Technical Summary

Technical Problem

When the airbags of existing vehicles collided, the occupants first accelerated the impact before the airbag was deployed, resulting in a large impact force, short cushioning distance and limited protection effect.

Method used

A collision protection device is designed, by providing an elastic member between the steering column and the steering wheel, and using a decoupling assembly to disengage the steering column from the steering column, the elastic member pushes the steering wheel away from the steering column, shortens the distance between the airbag and the occupant, and reduces the impact force.

Benefits of technology

By increasing elastic cushioning, the protection effect of the occupants is further improved, the impact force when the occupants come into contact with the airbag, and the protection performance of the airbag is improved.

Abstract

The utility model provides a collision protection device and a vehicle. The collision protection device comprises a steering column, a steering wheel, a decoupling assembly and an elastic piece, and a safety air bag is arranged on the steering wheel. The decoupling assembly is connected between the steering column and the steering wheel in a decoupling mode, the elastic piece is pre-tightened between the steering column and the steering wheel, and the elastic piece can push the steering wheel to move away from the steering column when the decoupling assembly and the steering wheel are decoupled. The distance between the safety air bag and the head and chest of the passenger is shortened, and the impact force generated when the passenger makes contact with the safety air bag is reduced; and after the passenger makes contact with the safety air bag, the steering wheel is pushed to compress the elastic piece to move in the direction close to the steering column, at the moment, the elastic piece plays a buffering role, a section of elastic buffering is added compared with a traditional safety air bag structure, and the protection effect on the passenger is further improved.
