The invention relates to the technical field of traffic safety, and discloses an anti-intrusion rear-end collision prevention rear beam of a truck. A shaft groove is formed in one end of the mountingplate; the four shaft grooves are distributed at one end of the mounting plate in an array manner; shaft supporting bases are fixedly installed on the two sides of the bottom of the shaft groove, a hydraulic rod is fixedly installed on the outer surface of the sleeve, sliding rails are movably installed on the two sides of the sliding block, springs are fixedly installed at the ends, located on the outer sides of the guide rods, of the inner sides of the sliding rails, and one ends of the springs are connected with the sliding block. When a car is just in contact with the motion stopping plateand the motion stopping plate rotates, the sliding block is driven to move towards the left side in the graph, and the spring contracts and absorbs the kinetic energy of the car; when the sliding block reaches the stroke limit, the hydraulic rod starts to contract to further absorb the kinetic energy of the car, and when the car is braked at the moment, the car head of the car cannot be impactedby the rotation of the motion stopping plate, so that unnecessary economic loss of the car owner is avoided.

    本发明涉及交通安全技术领域,且公开了一种货车防侵入式追尾防撞后梁,通过安装板的一端开设有轴槽,轴槽的数量为四个且阵列分布在安装板的一端,轴槽底部的两侧均固定安装有轴支撑座,套筒的外表面固定安装有液压杆,同时通过滑块的两侧活动安装有滑轨,滑轨内侧的一端且位于导杆外侧的位置上固定安装有弹簧,弹簧的一端与滑块相连。当小汽车刚刚接触到运动阻止板并使运动阻止板发生转动时,带动滑块向图中左侧的方向移动,并使弹簧发生收缩,吸收小汽车的动能,当滑块到达行程极限后,液压杆开始收缩,进一步吸收车辆的动能,当小汽车在此时已经刹停,运动阻止板的转动不会使小汽车的车头受到撞击,避免了小汽车车主受到不必要的经济损失。
