The invention provides a combined type automobile collision energy absorption box. The combined type automobile collision energy absorption box comprises an upper flange, a combined type energy absorber and a lower flange which are sequentially arranged from top to bottom. The combined type energy absorber comprises a hexagonal prism type supporting shell, a double-layer gradient type sandwich inner core arranged in the hexagonal prism type supporting shell and a circular-truncated-cone-shaped supporting base. The double-layer gradient sandwich inner core is composed of an upper arch shell structure, a middle corrugated pipe and a lower arch shell structure. A rotary thread is arranged at the end part of the arch shell structure; wherein the planes of the upper arch shell structure and the lower arch shell structure are oppositely arranged and are connected together through a corrugated pipe; the upper end face of the circular-truncated-cone-shaped supporting base is fixedly connected with the convex face of the arch shell structure on the lower portion.

    本发明提供了一种组合式汽车碰撞吸能盒,包括由上至下依次设置的上法兰、组合式吸能器及下法兰;所述组合式吸能器包括六棱柱型支撑外壳、置于六棱柱型支撑外壳内的双层梯度式三明治内芯及圆台型支撑底座;双层梯度式三明治内芯由上部的拱壳结构、中部的波纹管及下部的拱壳结构组成;拱壳结构端部布置有回旋式螺纹;其中上部的拱壳结构和下部的拱壳结构平面相向放置,并通过波纹管连接在一起;所述圆台型支撑底座的上端面与下部的拱壳结构的凸面固定连接。
