Problems solved by technology

However, the safety body of a car absorbs the collision energy by destroying the body structure, and the body deformed by the collision will cause crushing damage to the occupants of the car
The impact sensor of the airbag is affected by the installation position. When a collision occurs at different parts, the energy received by the impact sensor is different, and the gas generator cannot be reliably triggered. The gas generator does not work without a trigger signal, thus losing the protection for the occupants.

Abstract

The invention discloses a safety airbag of an automobile. The safety airbag can implement a buffer protection function on passengers and an automobile body. An outer airbag is connected with a gas charging valve and one end of a safety valve, the other end of the safety valve is connected with one end of a gas pipe, and the other end of the gas pipe is connected with an inner airbag. When collision occurs, the outer airbag which is charged with gas through the gas charging valve is subjected to external force, the gas inside the outer airbag is squeezed, the outer airbag deforms, and part of collision energy is absorbed. Simultaneously, the squeezed gas passes through the safety valve, when the gas pressure is high enough, the safety valve is switched on, the gas is delivered to the inner airbag through the gas pipe, the inner airbag is inflated, and the inflated inner airbag is used for preventing passengers from directly colliding with automobile parts and stopping the movement inertia of passengers.

Description

technical field [0001] The invention relates to an automobile safety airbag, in particular to a safety airbag capable of cushioning and protecting passengers and automobile bodies. Background technique [0002] The passive safety protection device of a general automobile is mainly composed of a safety body, a seat belt, and an airbag. When the car collides, the energy-absorbing area of ​​the safety body is subjected to external force, and linear deformation and collapse occur, absorbing most of the collision energy. At the same time, the impact sensor of the airbag triggers the gas generator, and the gas generator ignites and detonates quickly after receiving the ignition signal. The explosion generates a large amount of gas to inflate the airbag, and the inflated airbag stops the occupant's motion inertia to prevent the occupant from directly colliding with the car parts. Reduces damage taken by crew members. However, the safety body of a car realizes the absorption of co...
