Airbag use introduction

When the car is in a major accident, the airbag will pop up to prevent the occupants from getting a greater impact. Then the question arises. Can the airbag be used again after it pops up? The airbag has opened the lid. Can the steering wheel be used? And so on. Xiao Bian talks about airbag related problems today.

In fact, there are many airbags on the car, especially some cars that are known for their safety. The most commonly heard is that it has 24 airbags, so it will not be completely used during a crash.

1. Can airbags be recycled after being ejected?

The airbag refers to a device for inflating an airbag to protect an occupant before the vehicle occupies a secondary collision when the vehicle crashes. The airbag is an auxiliary device for the occupant restraint device of the seat belt, so it is necessary to fasten the seat belt when driving. The car airbag is not reusable after being ejected. It is disposable, but it can be installed again.

2. How does the airbag work?

When an impact occurs, the sensor detects the impact and the relevant control system will determine the degree of collision to determine whether to trigger the inflator. It is usually the gas generator that generates the ignition action according to the signal, ignites the solid fuel and produces gas to inflate the airbag. Due to the very short time of the impact process, the airbag generally takes about 25-35 milliseconds from the trigger to the completion of the inflation process. If the inflation time is too long, it will lose its effect.

3. Can the steering wheel be used after the airbag is broken?

The position of the general airbag pop-up is in the center of the steering wheel, so only the airbag and airbag computer need to be replaced, and the steering wheel does not need to be replaced. Owners don't have to worry about the cover on the airbags bouncing on themselves, because there will be a part of the airbag cover connected to the steering wheel when it is opened, and it will not be bombarded.

Someone may ask, if you stride hard on the steering wheel, the airbag will not pop up? Do not worry about this issue. Because the pop-up of the airbag is transmitted by the sensor outside the car to the computer in the event of a strong impact, the computer then triggers a gas explosion in the airbag ignition trigger to generate high-pressure gas, and instantly pop out to achieve the purpose of protecting people.

Airbags are related to our driving safety. Therefore, we must wear safety belts when driving and strictly abide by traffic regulations to ensure our own safety.


CNC lathe is one of the most widely used CNC machine tools.
CNC lathe is mainly used for processing shaft, disc and other parts of the rotary.
Through the operation of numerical control machining program, it can automatically finish the cutting processing of inner and outer cylindrical surface, conical surface, forming surface, thread and end face, and can carry out the work of turning groove, drilling, reaming, reaming and so on.
The turning center can complete more processing procedures in a single clamping, improving the processing accuracy and production efficiency, especially suitable for the processing of complicated rotary parts.
Some common machine tools can not or inconvenient processing parts, processing quality stability, reduce the labor intensity of workers.
