The invention provides a multi-gradient energy absorption device based on a Kresling paper folding structure. The multi-gradient energy absorption device comprises a left-handed Kresling basic unit and a right-handed Kresling basic unit, the top surface and the bottom surface of the left-handed Kringing basic unit and the top surface and the bottom surface of the right-handed Kringing basic unit are respectively of a polygonal structure; at least two left-handed Kresling basic units are vertically arranged to form the energy absorption device. Or at least two right-handed Kresling basic units are vertically arranged to form the energy absorption device; or the left-handed Kresling basic unit and the right-handed Kresling basic unit are vertically arranged to form the energy absorption device; the energy absorption device is filled with energy absorption substances. According to the invention, the foam material can be greatly compressed in the collision compression process, so that more impact energy can be absorbed and dissipated. The pipe fitting is formed by spatially folding a planar material, and compared with a metal pultrusion technology for manufacturing the section of the pipe fitting into a multi-cell shape, a multi-angle shape and the like, the manufacturing cost is greatly reduced.

    本发明提供一种基于Kresling折纸结构的多重梯度吸能装置,包括:左手性Kresling基础单元和右手性Kresling基础单元;左手性Kresling基础单元的顶面和底面以及右手性Kresling基础单元的顶面和底面分别为多边形结构;由至少两个左手性Kresling基础单元呈竖向排列组成吸能装置;或由至少两个右手性Kresling基础单元呈竖向排列组成吸能装置;或由左手性Kresling基础单元和右手性Kresling基础单元呈竖向排列组成吸能装置;吸能装置内部填充有吸能物质。本发明可以实现碰撞压缩过程中,泡沫材料的极大压缩,从而吸收、耗散更多的冲击能量。本发明还通过平面材料空间折叠而成,相比利用金属拉挤技术将管件截面制作成多胞、多角等形状,制造成本大大降低。
