How to repair the car airbag

1. The airbag of the car popped up, so you can't take a shower and you have to replace it.

2. Car airbags are disposable products. When a vehicle has an accident, the airbag will be invalid after being activated and need to be replaced with a new one.

3. The principle of automobile airbag is as follows: 1.

4. When the car collides during driving, the airbag sensor first receives the collision signal. As long as the specified strength is reached, the sensor will act and send a signal to the electronic controller; 2. After receiving the signal, the electronic controller compares it with the original stored signal, and if the airbag deployment condition is met, the driving circuit sends a start signal to the gas generator in the airbag module; 3. After the gas generator receives the signal, it ignites the gas generator to generate a large amount of gas, which enters the airbag after filtering and cooling, so that the airbag breaks through the inner container and expands rapidly in a very short time, forming an elastic air cushion in front of the driver or passenger to leak and contract in time to absorb the impact energy, thus effectively protecting the head and chest of the human body from injury or reducing the degree of injury.
