The invention discloses an energy absorption box filled with a multi-direction compression structure, which is positioned between an anti-collision beam and a front longitudinal beam, is arranged on the inner side of a bent part of the anti-collision beam and is made of a negative poisson ratio material. The position, making contact with the curved surface of the anti-collision beam, of the energy absorption box is matched with the curvature of the curved surface of the anti-collision beam, the energy absorption box comprises a plurality of regularly-arranged cell element structures, and the cell element structures are of a cut-off structure. The interior of the cell element structure is filled with a three-dimensional supporting structure at least comprising three supporting directions, and the multiple supporting directions correspond to the radian range of the curved surface position of the anti-collision beam. According to the multi-direction buffer structure, absorption of impact energy in different directions is achieved, and actually, due to the multi-direction non-rectangular and non-single axial structure, the device can be matched with the curvature of a curved surface structure of an anti-collision beam.
本发明公开的一种多方向压缩结构填充的吸能盒,所述吸能盒位于防撞梁和前纵梁之间,所述吸能盒设置在所述防撞梁的弯曲部位内侧,所述吸能盒为负泊松比材料。所述吸能盒接触所述防撞梁曲面位置与之曲率匹配,所述吸能盒包括若干规整排布的胞元结构,所述胞元结构为截断结构;所述胞元结构内部填充至少包括3个支撑方向的立体支撑结构,多个所述支撑方向均对应所述防撞梁曲面位置的弧度范围内。本发明的多方向缓冲结构实现了对不同方向撞击能量的吸收,实际上这种多方向的非矩形、非单一轴向结构还使得装置能够构成与防撞梁的曲面结构曲率匹配。
