Car airbags should be known to everyone who owns a car. To explain it in a literal sense, it is used to protect passengers as well as drivers from driving a safe vehicle. Of course, when the car is in a safe driving process, the airbag will not have any effect at all, and only when the car has an emergency, the airbag will be the steering wheel or the measuring instrument and the back of the seat. Pop up to protect the human body from impact damage. Therefore, in order to maximize the safety of themselves and their families and passengers in an accident, I should do a better job of car care and maintenance in daily life to better understand the working principle of the airbag.
The main components of an airbag are a combination of several components such as airbags, airbags, microprocessors, sensors, and gas generators. The operating principles are as follows:
1. If the car is loaded, the microprocessor and sensor will confidently determine how large the collision is, and then transmit and send signals to the gas generator.
2. When the gas generator receives the signal, it will ignite. After the solid fuel is ignited, it will produce gas to inflate the airbag, so that the airbag will rapidly expand to ensure the safety of the passengers.
3, airbags will have set safety valve, if it is after the detonation of the airbag pressure has reached almost the same value or after the inflation has been excessive, it will automatically release part of the gas, so as not to passengers or drivers Crush injury.
4. Compared with general airbags, smart airbags only add a sensor on the basis of the original and can detect whether adults or children sit on the seat and then Seat height and position are used to control the degree of inflation and inflation of the airbag. The gas used inside the airbag is mostly carbon monoxide or nitrogen. (Text | Sun Ni)
