The invention provides a multi-stage bearing automobile energy absorption box. The multi-stage bearing automobile energy absorption box comprises a hexagonal pyramid shell, a first-stage energy absorption device, a second-stage energy absorption device and a trigger supporting column, wherein the hexagonal pyramid shell is filled with the first-stage energy absorption device and the second-stage energy absorption device from outside to inside; the first-stage energy absorber and the second-stage energy absorber have height differences with the trigger supporting column in the filling process, and the first-stage energy absorber and the second-stage energy absorber are divided into a low-speed energy absorption area, a medium-speed energy absorption area and a high-speed energy absorption area through the energy absorption box. In order to solve the problems that a traditional energy absorption box is low in energy absorption efficiency, poor in bearing characteristic and load demand matching performance and the like, a series of novel metamaterial designs are provided, and the energy absorption box structure with efficient energy absorption and multi-stage bearing is developed through reasonable matching of the functions of the metamaterial designs.
本发明提供了一种多级承载的汽车吸能盒,包括:六棱锥外壳、由外至内填充在六棱锥外壳内的一级吸能器、二级吸能器、以及触发支撑柱;所述一级吸能器,二级吸能器在填充过程中与触发支撑柱存在高度差,以降吸能盒分为低速吸能区、中速吸能区和高速吸能区。本发明针对传统吸能盒吸能效率低,承载特性与载荷需求匹配性差等问题,提出一系列新型的超材料设计,通过对其功能的合理匹配,开发了一种具备高效吸能和多级承载的吸能盒结构。
