The controller controls the ignition control logic of the igniter according to the collision intensity signal monitored by the collision intensity sensor, and the control can be realized according to the existing mature algorithm.
Optionally, the airbag assembly further comprises a safety collision sensor (not shown), the safety collision sensor is fixedly connected with the vehicle body, and the output end of the safety collision sensor is in communication connection with the input end of the controller. This arrangement prevents the controller from erroneously controlling the ignition of the igniter due to a failure of the collision strength sensor, and thus, the airbag 3 is erroneously opened.
The controller receives the safety intensity signal and compares the safety intensity signal with a preset safety threshold value prestored inside, and the preset safety threshold value is slightly smaller than the preset intensity threshold value. When the safety intensity signal is greater than or equal to the set safety threshold and the collision intensity signal is greater than or equal to the set intensity threshold, it indicates that the vehicle has a relatively strong collision and the airbag 3 needs to be opened to protect a person, at this time, the controller sends the ignition signal to the control end of the igniter to control the igniter to ignite, so as to ignite the ignition agent and generate a large amount of gas to fill the airbag 3, so that the airbag 3 is inflated on the side of the front seat and in front of the rear seat; when the collision strength signal is greater than or equal to the set strength threshold value, but the safety strength signal is less than the set safety threshold value, it indicates that the collision strength sensor is in fault, at this time, the vehicle does not collide strongly, the controller does not output an ignition signal, and the airbag 3 is not opened. According to the practical application condition, the set intensity threshold value and the set safety threshold value can be adjusted.
The use of the airbag assembly is described further below:
when a vehicle collides, the collision intensity sensor monitors a collision intensity signal and transmits the collision intensity signal to the controller, the safety collision sensor monitors a safety intensity signal and transmits the safety intensity signal to the controller, the controller compares the collision intensity signal with the preset intensity threshold value prestored in the controller and compares the safety intensity signal with the preset safety threshold value prestored in the controller, when the collision intensity signal is greater than or equal to the preset intensity threshold value and the safety intensity signal is greater than or equal to the preset safety threshold value, the vehicle is indicated to have stronger collision, at the moment, the controller outputs an ignition signal to the control end of the igniter to control the igniter to ignite, so that the igniter burns to generate a large amount of high-pressure gas, and the high-pressure gas enters the air bag 3 through the exhaust port of the gas generator 1 and the communicated air guide pipe 2, the airbag 3 is inflated, and after the airbag 3 is inflated, a first inflation section 31 thereof extends and inflates in the front-rear direction of the vehicle body at the side of the front seat 8 where the airbag 3 is installed, thereby protecting the side of the front passenger from a collision, and the second inflation section 32 communicating with the first inflation section 31 extends and inflates in the width direction of the rear seat between the front seat 8 and the rear seat, thereby protecting the front of the rear passenger from a collision.
With the airbag assembly of the present invention, the bag 3 is disposed on the side wall of the front seat, and after the bag 3 is inflated and deployed, the side of the front seat can be extended and inflated in the front-rear direction of the vehicle body by the first inflation section 31 to protect the side of the front passenger from injury, and the front of the rear seat can be extended and inflated by the second inflation section 32 to protect the front of the rear passenger from injury.
The invention also provides a vehicle, which comprises a vehicle body, a front row seat 8 and a rear row seat (not shown) which are installed in the vehicle body, and the vehicle further comprises the safety airbag assembly of any one of the embodiments, wherein an air bag 3 of the safety airbag assembly is fixedly connected with the side wall of the seat framework of the front row seat 8, and a generator bracket 6 of the safety airbag assembly is fixedly connected with one side, facing the rear row seat, of the seat framework of the front row seat 8 on which the air bag 3 is installed.
