Abstract

The invention discloses a mechanical airbag. The mechanical airbag comprises steering wheel outer rings, plastic package covering the steering wheel outer rings, a steering wheel frame, an airbag cover, a gas generator end cover, a shell, shell air outlet holes, a combustion outer wall, combustion outer wall air outlet holes, a combustion inner wall, combustion inner wall air outlet holes, a combustion cavity, flash holes, gunpowder, a firing chamber, eccentric springs, an offset pin, ignition pin compression springs, an ignition pin, a detonator, a locking shaft, a locking pin blocking arm, an impact sensor ball, a frizzen, and a torsion spring. The mechanical airbag mainly adopts a mechanical structure, the impact sensor ball is assisted, application of the number of electronic components is reduced, so that the failure rate of the electronic components is also reduced greatly, and the normal working rate of the airbag is improved to ensure the safety of passengers.

Description

technical field [0001] The invention relates to an airbag, in particular to a mechanical safety airbag. Background technique [0002] The working principle of the airbag is that when the car has a frontal collision accident, the airbag control system detects that the impact force (deceleration) exceeds the set value, the airbag computer immediately connects the electric squib circuit in the inflatable component, and ignites the airbag. The ignition medium in the electric detonator, the flame ignites the ignition powder and the gas generating agent, and produces a large amount of gas, which inflates the airbag within 0.03 seconds, causing the airbag to inflate rapidly, breaking through the decorative cover plate on the steering wheel and drumming towards the driver and passengers. The head and chest of the driver and passengers are pressed on the gas-filled airbag. The whole process of this method relies on electronic control, and it is very easy for an electronic component t...
