The device comprises a sensor arranged on the side face of an vehicle body, the sensor is used for detecting the approaching speed of an object on the side face of the vehicle body, and the data output end of the sensor is connected with an electronic control unit ECU; the ECU is used for comparing the approaching speed detected by the sensor with a preset threshold value, and the output end of the ECU is connected with the igniter. When the data received by the sensor reaches the threshold value of the ECU, the sensor sends the data to the ECU; the electronic control unit sends a signal to the igniter; the igniter ignites the inflating agent, the gas pushes out the telescopic pipe, and the impact force acts on the vehicle door outer plate, the energy-absorbing telescopic section and the gas in each telescopic section pipe, so that the metal part deforms, the gas is pressurized to increase the kinetic energy of the gas, the impact energy is absorbed and consumed, and the purpose of protecting the personal safety of passengers is achieved.

    本发明公开了一种用于缓冲汽车侧面撞击的装置,包括设置在车体侧面的传感器,传感器用于检测车体侧方物体的靠近速度,传感器的数据输出端与电子控制单元ECU连接;所述电子控制单元ECU用于比较传感器检测到的靠近速度和预设阈值,电子控制单元ECU的输出端与点火器连接。当传感器接收到的数据达到电子控制单元ECU的阈值时,电子控制单元发出信号给点火器,点火器点燃充气剂,气体将伸缩管推出,通过撞击力对车门外板和吸能伸缩段以及各伸缩段管内气体做功,使金属件形变和对气体加压增加气体动能,来吸收和消耗掉撞击能,达到保护乘客的人生安全的目的。
