The invention discloses a hedgehog-imitating type energy absorption box comprising an energy absorption box body, a protective sleeve and a connecting plate, the energy absorption box body and the connecting plate are of an integrated structure, are made of a low-density 3D printing high polymer material and can be formed at a time, defects are not prone to being formed, the operation reliability of the energy absorption box is effectively improved, and the manufacturing cost is reduced. The energy absorption box is different from an existing energy absorption box in a wrinkle deformation mode, the deformation mode that the middle is expanded and fractured is adopted, a large amount of collision energy can be absorbed before fracture failure occurs, and energy absorption of higher unit mass is achieved.
本发明公开了一种仿刺猬刺型吸能盒,包括吸能盒主体、保护套以及连接板,吸能盒主体与连接板为一体化结构,采用密度较低的3D打印高聚物材料制成,一次即可成型,不易形成缺陷,有效地提高了吸能盒的运行可靠性,并降低了制造成本。本吸能盒与现有吸能盒的褶皱变形模式不同,采用的是中部膨胀断裂的变形模式,在发生断裂失效前可以吸收大量的碰撞能量,具有更高单位质量的吸能。
