The anti-collision cross beam of the automobile rear bumper comprises a rear cross beam, a protection steel plate is fixedly connected to the right side of the rear cross beam, and a groove is formed in the right side of the protection steel plate. According to the anti-collision cross beam of the rear bumper of the automobile, under the elastic acting force of the compression thrust spring and the air compression spring, the plastic bumper is collided under low-speed collision, and the plastic bumper is prevented from being collided under the condition of left-right buffering displacement; the upper clamping block and the lower clamping block are used for carrying out prestress extrusion fixing on the prestress arc-shaped steel plate set sleeve, prestress anti-collision energy in the direction opposite to the direction of strong impact force is achieved, sand contained in the wear-resisting anti-collision sandbag is matched for carrying out anti-collision energy absorption, the impact force is effectively buffered and absorbed, and the service life of the wear-resisting anti-collision sandbag is prolonged. And meanwhile, the first buffering high-density plastic block and the second buffering high-density plastic block are mutually extruded, and the impact force is absorbed through the materials of the first buffering high-density plastic block and the second buffering high-density plastic block.
本发明公开了一种汽车后保险杠的防撞横梁,包括后横梁,后横梁的右侧固定连接有保护钢板,保护钢板的右侧开设有凹槽。该汽车后保险杠的防撞横梁,通过塑料保险杠在压缩推力弹簧和空气压缩弹簧的弹性作用力下,使其在低速碰撞下,塑料保险杠受撞通过左右缓冲位移的情况对其进行防撞,并通过上下两个卡接块对其预应力弧形钢板组套进行的预应力挤压固定,具备与强烈撞击力相反方向的预应力抗撞能量,并配合耐磨防撞沙袋里装有的砂子进行抗撞吸能,对其撞击力进行有效的缓冲吸能,同时再配合相互挤压第一缓冲高密度塑胶块和第二缓冲高密度塑胶块,利用第一缓冲高密度塑胶块和第二缓冲高密度塑胶块的材质对其撞击力进行吸收的效果。
