Car airbags also have a "shelf life"

Airbags, ABS brake anti-lock braking systems, etc. have become essential safety equipment for most cars. These indispensable safety equipments have also become important reference factors for consumers to purchase cars. Can you know that these safety equipments are also very delicate and require careful maintenance and care.

Airbags have become the standard safety configuration on most cars, and some have side airbags, knee airbags, and head air curtains.

The airbag is made of nylon material and contains 100 grams of sodium azide. In the event of an accident, the sensor ignites the igniter to ignite the igniting agent. When sodium azide is heated, it immediately releases nitrogen gas and instantly fills the airbag. A large balloon is instantaneously formed, thus acting as a buffer.

When the collision occurs, the controller of the airbag recognizes and judges the strength of the collision according to the acceleration signal sent by the sensor. When the collision strength reaches the design condition, the sensor that detonates the airbag rapidly touches the igniter to detonate the nitrogen solid particles to form a rapidly expanding gas. The bag protects the head from damage by cushioning the impact of the front passengers. Geely Automobile's after-sales service manager Zhu Ce said: "The sensor will automatically calculate the intensity of the collision, and it will not cause the airbag to detonate due to improper operation of the driver, the vehicle encountering a small obstacle or a lighter collision."

The use of airbags alone does not work well and must be used with seat belts to ensure driving safety. The use of airbags should pay attention to: The safety factor for automobiles with airbags is improved, but the airbags have a shelf life. The maintenance of airbags is not as intuitive as the appearance and maintenance of the car body, and it is easily overlooked. Without regard to the maintenance of airbags, airbags may become “invisible killers”.

Owners are advised not to place perfume bottles and paste jewelry at the front airbags. Usually, you should avoid high temperature and static electricity. Do not leave the airbag and the sensor in a high temperature and static environment so as not to cause the airbag to open incorrectly. Also avoid accidental bumps and vibrations of the airbag sensor to avoid sudden opening of the airbag. Do not change the airbag system and its surrounding arrangements without authorization. Do not change the front bumper and the vehicle front structure without authorization. Airbags are not suitable for all occupants. Try to avoid young children and seniors sitting in the co-pilot position with airbags. Also do not put children between the driver and the steering wheel, and do not allow children to face the dashboard to avoid The airbags hurt them when they burst.

Normally, the airbag will not malfunction during the normal use cycle. After every 1 to 20,000 kilometers, the airbag and its accessories can be inspected at the 4S shop. However, after ten years of use, the quality of the airbag is difficult to guarantee. It must be carried out. Thorough testing, if any, should be replaced promptly. Master Li Xiaobin pointed out that the airbag indicator is still flashing or long-lived after 6 seconds to 8 seconds after the vehicle starts, indicating that the airbag is faulty; during the operation of the vehicle, the airbag indicator flashes brightly after 5 seconds. It also indicates The airbag has malfunctioned. This must be checked and handled in time at the 4S shop. Do not let the airbag become a "killer."
