Product Description
1. Collision sensors: A number of collision sensors are installed on the vehicle, which can detect the impact force and direction when a collision occurs. These sensors can be located at the front, side and top of the vehicle to sense collisions in different directions.
2. Airbag control unit: Airbag control unit is an electronic control device, which is usually located in the central control system of the vehicle. It receives the signal from the collision sensor and judges whether it is necessary to trigger the airbag inflator according to the strength and direction of the signal.
3. Airbag inflator: Airbag inflator is a device filled with gas or chemical substances, usually located near the air bag hairspring. When the airbag control unit judges that inflation is needed, it will activate the airbag inflator through an electrical signal.
4. Airbag hairspring: Airbag hairspring is a filament or line connecting the airbag inflator and the airbag. When the airbag inflator is activated, the airbag hairspring will be quickly pulled to inflate and deploy the airbag.
5. airbag deployment: once the airbag is inflated, the airbag hairspring will be rapidly deployed to form an inflated protective barrier. This barrier can reduce the impact of passengers in the collision and protect important parts such as head, chest and abdomen from the damage caused by the collision.
In a word, the working principle of the airbag hairspring is based on the signal of the collision sensor and the judgment of the airbag control unit. By activating the airbag inflation device, the airbag hairspring can be inflated and deployed quickly, providing a protective barrier and reducing the risk of injury to passengers in collision. This process is automatic and can respond quickly when a collision occurs, providing additional safety protection for the occupants.
