The invention discloses an automobile headlamp collision protection system which comprises an automobile headlamp, a cutting device and a plastic connecting piece. The cutting device is electrically connected with an automobile ECU. The automobile headlamp is fixedly installed on the two sides of the upper front portion of an automobile body through a plurality of plastic connecting pieces, and agap is reserved between the automobile headlamp and the automobile body. The cutting device is fixedly installed on the side edge of the automobile headlamp, a movable cutting part is arranged in thecutting device, and the extending direction of the cutting part is aligned with the plastic connecting pieces; and when the automobile ECU receives a collision signal detected by an automobile front induction device, the automobile ECU enables the cutting part of the cutting device to stretch out and cut off the plastic connecting pieces so that the automobile headlamp is disconnected from the automobile body in a rigid mode, and the automobile headlamp is extruded to move along with a collided pedestrian/object through the gap. According to the invention, the normal mounting strength requirement of the automobile headlamp is met, and buffer protection during headlamp collision is added so that the damage degree to the pedestrian or the object during automobile collision is reduced.

    本发明公开了一种汽车大灯碰撞保护系统,包括汽车大灯、切割装置、塑料连接件;切割装置与汽车ECU电连接;汽车大灯通过多个塑料连接件固定安装于汽车车身前上部两侧,且汽车大灯与汽车车身之间留有间隙;切割装置固定安装于汽车大灯的侧边,切割装置内设有活动切割部,且切割部的伸出方向对准塑料连接件;汽车ECU接收到汽车前部感应装置检测的碰撞信号时,控制切割装置的切割部伸出并切断塑料连接件,使汽车大灯与汽车车身断开刚性连接,并通过间隙使汽车大灯随碰撞行人/物体一起挤压运动。本发明满足汽车大灯的正常安装强度需求外,增加了大灯碰撞时的缓冲保护,以此减少汽车碰撞次时对行人或物体的伤害程度。
