The multi-stage energy absorption box structure comprises an upper energy absorption box and a lower energy absorption box, the lower energy absorption box is connected with a bottom plate through welding, longitudinal guide grooves and upper riveting pits are distributed in the upper energy absorption box, and lower riveting pits are formed in the positions, corresponding to the riveting pits of the upper energy absorption box, of the lower energy absorption box. The upper energy absorption box and the lower energy absorption box are clamped together through the upper riveting pit and the lower riveting pit; and riveting point positions are formed at the positions of the upper riveting concave pits and the lower riveting concave pits. The anti-collision beam energy absorption box of the multi-stage structure has double functions in the collision process, firstly, a certain support is provided for the front skin before the anti-collision beam energy absorption box is broken at the riveting position, and pedestrians are prevented from being drawn into the vehicle bottom so as to be protected; and after the upper energy absorption box slides into the lower energy absorption box, the upper energy absorption box and the lower energy absorption box can be continuously crushed together to absorb collision energy, so that a vehicle body is protected, and damage to the vehicle body is reduced.

    本发明涉及一种兼顾保护行人和车身的多级吸能盒结构,包括上吸能盒和下吸能盒,下吸能盒通过焊接与底板连接,上吸能盒布有纵行的引导槽和上扎铆凹坑,下吸能盒对应上吸能盒的扎铆凹坑的位置上设置有下扎铆凹坑,上吸能盒、下吸能盒通过上扎铆凹坑和下扎铆凹坑卡接在一起;上扎铆凹坑和下扎铆凹坑所处位置形成扎铆点位。本发明多级结构的防撞梁吸能盒在碰撞过程中有双重作用,首先在铆接位置处断开前给予前蒙皮一定的支撑,防止行人卷入车底以保护行人;然后在上吸能盒滑入下吸能盒后,可继续和下吸能盒一起进行压溃吸能碰撞能量,以保护车身,降低车体的损伤。
