The invention relates to the technical field of vehicle protection, and relates to an energy-absorbing anti-collision mechanism for a truck. The anti-collision mechanism comprises a sliding rail, a sliding block, a containing rack, a spare tire and a stop lever. The sliding rail is used for being fixed to a girder at the tail of a truck and is arranged in the length direction of the truck; the sliding block is arranged on the sliding rail; the containing rack is arranged on the lower side of the sliding block in a liftable manner; the spare tire is used for being detachably mounted on the containing rack and extends out of the tail part of the containing rack; one end of the stop lever is rotationally connected with the girder; and the stop lever is pushed by the containing rack to rotatewhen the sliding block slides forwards, so that the other end of the stop lever abuts against the ground. According to the technical scheme, due to the fact that the spare tire is the flexible part, collision of a sedan can be buffered, and casualties are reduced; and besides, after being collided, the stop lever abuts against the ground, so that the stop lever can transmit part of impact force ofthe sedan to the ground, and the impact force of the sedan on the truck girder can be reduced.

    本发明涉及车辆防护技术领域,它涉及一种用于货车的吸能防撞机构,该防撞机构包括滑轨、滑块、放置架、备用轮胎和挡杆。滑轨用于固定在货车尾部的大梁上、且沿货车的长度方向设置;滑块设置在滑轨上;放置架可升降地设置在滑块的下侧;备用轮胎用于可拆卸地安装在放置架上、且从放置架的尾部伸出;挡杆的一端与大梁转动连接;挡杆用于在滑块向前滑动时受放置架推动发生转动,以使另一端与地面相抵。根据本发明的技术方案,由于备用轮胎为柔性件,从而可以对小轿车的撞击进行缓冲,降低人员伤亡;另外,由于受到撞击后,挡杆与地面相抵,从而挡杆可以将小轿车的部分冲击力传导至地面,如此可以减小轿车对货车大梁的冲击力。
