The invention relates to the technical field of automobiles, and discloses a paper folding structure energy absorption box with zero Poisson's ratio property, which comprises an equilateral polygon paper folding structure at the upper part and a base at the lower part, the equilateral polygon paper folding structure is connected with the base through welding or riveting, the equilateral polygon paper folding structure is composed of four groups of energy absorption bodies, and the energy absorption bodies are connected with the equilateral polygon paper folding structure through welding or riveting. Every two adjacent sets of energy absorption bodies are arranged in a mirror image mode, the protruding parts on the energy absorption bodies are wave crests, the inwards-concave parts on the energy absorption bodies are wave troughs, creases are formed in the connecting positions of the wave crests and the wave troughs, and the energy absorption bodies can contract and absorb energy in the direction of the creases when being pressed. When being impacted by an external load, the paper folding structure shrinks along the crease, so that the problems that the energy absorption effect is poor and the crumple effect of the energy absorption box is not obvious due to the unreasonable design of a guide groove of an existing energy absorption box are solved.

    本发明涉及汽车技术领域,且公开了一种具有零泊松比性质的折纸结构吸能盒,包括上部的等边多边形折纸结构与下方的底座组成,等边多边形折纸结构与底座之间通过焊接或者铆接连接,等边多边形折纸结构由四组吸能体组成,相邻的两组吸能体为镜像设置,吸能体上凸出部分为波峰,吸能体上内凹部分为波谷,波峰与波谷连接处形成折痕,吸能体上受压时会沿折痕方向收缩吸能,该具有零泊松比性质的折纸结构吸能盒及其设计方法,吸能盒的吸能体部分,在受到外部载荷冲击时,折纸结构会顺着折痕处收缩,解决了现有的吸能盒引导槽设计不合理导致吸能效果差,吸能盒溃缩效应不明显的问题。
