The invention aims to provide an automobile anti-collision energy-absorbing assembly which comprises a shell, an upper plugging nut and a lower plugging nut, the upper plugging nut and the lower plugging nut plug the upper end and the lower end of the shell respectively, a step piece is formed in the shell, a packing nut is arranged at the position of the step piece. The packing nut is in step fit with the step piece, the interior of the shell is packed into a first space and a second space, the first space is filled with hydraulic oil, and the second space is filled with small-particle-size hard plastic beads; the anti-collision energy absorption assembly can provide streamline deformation so as to continuously absorb energy, the problem of fluctuation of energy absorption buffering force is solved, the energy absorption effect is improved through filling of small-particle-size hard plastic beads and mutual friction force, and meanwhile secondary danger caused by leakage of a large amount of hydraulic oil in a hydraulic cylinder due to collision damage is prevented.
本发明的目的在于提供一种汽车防撞吸能组件,包括壳体、上封堵螺帽、下封堵螺帽,所述上封堵螺帽和下封堵螺帽分别封堵壳体的上下两端,所述壳体内部形成有台阶部,所述台阶部位置处设置有封隔螺帽,所述封隔螺帽与所述台阶部形成台阶配合,将所述壳体内部封隔为第一空间和第二空间,所述第一空间内灌注液压油,所述第二空间内填充小粒径的硬塑料珠;该防撞吸能组件可以提供流线型形变以能够连续型吸能,消除吸能缓冲力波动问题,通过填充小粒径硬塑料珠,通过相互摩擦力增加吸能效果,同时防止因撞击受损导致液压缸内液压油大量泄漏导致的二次危险。
