The invention relates to the technical field of automobiles, and discloses an automobile collision energy-absorbing buffer device which comprises a box body and an energy-absorbing plate, an abutting plate is slidably mounted in the box body, a plurality of energy-absorbing springs are arranged between the energy-absorbing plate and the abutting plate, one end of each energy-absorbing spring is fixedly connected with the abutting plate, and the other end of each energy-absorbing spring is fixedly connected with the energy-absorbing plate. Sliding rods are fixedly connected to the two ends of the energy absorption plate, the two sliding rods are slidably connected with the two side walls of the box body correspondingly, and a plurality of limiting assemblies are arranged on the box body and used for limiting the abutting plate; by arranging a plurality of limiting assemblies, multi-stage energy absorption is achieved, an energy absorption spring can achieve multiple energy absorption effects, a good energy absorption effect can be achieved, the energy absorption spring is used for energy absorption, energy is released through movement of an abutting plate, within a certain impact force, the device does not deform, and the impact strength of the device is improved. And during follow-up repair, only the abutting plate needs to be moved to be reset, later repair is facilitated, and the maintenance cost is reduced.

    本发明涉及汽车技术领域,公开了一种汽车碰撞吸能缓冲装置,包括盒体和吸能板,盒体的内部滑动安装有抵板,吸能板和抵板之间设置有多个吸能弹簧,吸能弹簧的一端与抵板固定连接,吸能弹簧的另一端与吸能板固定连接,吸能板的两端均固定连接有滑杆,两个滑杆分别与盒体的两侧壁滑动连接,盒体上设置有多组限位组件,限位组件用于对抵板进行限位;本发明通过设置多组限位组件,实现了多级吸能,使得吸能弹簧能够起到多次吸能作用,能够起到较好的吸能作用,利用吸能弹簧进行吸能,通过抵板的移动释放能量,在一定撞击力度内,装置不会发生形变,后续修复时只需移动抵板使其复位即可,便于后期进行修复,降低了维修成本。
