The invention provides an impact damping device which is installed on a frame of an automobile in a module mode, and the impact damping device comprises a speed sensor which detects the running speed of the automobile; a distance sensor that measures a distance between the vehicle and an object in front of or behind the vehicle; a collision perception determination unit that determines the possibility of a collision between the vehicle and the object on the basis of the traveling speed of the vehicle and the distance information from the object; a buffer cylinder; a piston which is provided so as to be movable inside the cushion cylinder and which is connected to the shock-absorbing bumper in the front thereof; and a gas generating device which is adjacent to the head of the piston behind the cushion cylinder and is provided inside the cushion cylinder.

    本发明提供一种冲击衰减装置,作为一种以模块安装在汽车的框架的冲击衰减装置,包括:速度传感器,其对车辆的行驶速度进行检测;距离感知传感器,其对车辆与车辆前方或后方物体的距离进行测量;碰撞感知判断部,其基于车辆的行驶速度和与物体的距离信息,判断车辆与物体的碰撞可能性;缓冲气缸;活塞,其在缓冲气缸内部以可移动的形式设置,并且在前方与吸收冲击用保险杠相连接;以及气体发生装置,其在缓冲气缸的后方与活塞的头部相邻,并设置于缓冲气缸的内部。
