The invention belongs to the field of vehicle bottom protection, and particularly relates to a bottom protection structure containing a negative-Poisson-ratio honeycomb material. The bottom protectionstructure comprises a basic protective assembly and a protective assembly sandwich layer, wherein the basic protection assembly comprises an upper plate, a bottom plate and a fixing structure used for fixing the protection assembly sandwich layer; the protection assembly sandwich layer comprises the negative-Poisson-ratio honeycomb material, an upper panel arranged on the negative-Poisson-ratio honeycomb material and a lower panel arranged below the negative-Poisson-ratio honeycomb material; and the protection assembly sandwich layer is fixed by the upper panel and the lower panel through thefixing structure for fixing the protection assembly sandwich layer. According to the protection structure, the bottom plate is designed to be of a trapezoidal structure, and the negative-Poisson-ratio honeycomb material is installed between the upper plate and the bottom plate to serve as a main energy absorption structure, so impact energy generated by explosion can be effectively absorbed; andthe negative-Poisson-ratio honeycomb material and a sandwich lightning protection assembly are combined with each other, so the energy absorption effect of the lightning protection assembly is greatlyimproved, and the safety of passengers is better guaranteed.

    本发明属于车辆底部防护领域,具体涉及一种含负泊松比蜂窝材料的底部防护结构。包括:基础防护组件和防护组件夹芯层;基础防护组件包括上板、底板和用于固定防护组件夹芯层的固定结构;防护组件夹芯层:包括负泊松比蜂窝材料、设置在负泊松比蜂窝材料上的上面板和设置在负泊松比蜂窝材料下的下面板;防护组件夹芯层通过上面板和下面板通过用于固定防护组件夹芯层的固定结构实现固定。本发明的防护结构,将底板设计为梯形结构,在上板与底板之间安装负泊松比蜂窝材料作为主要吸能结构,能够有效地吸收爆炸所产生的冲击能量;将负泊松比蜂窝材料与“三明治”防雷组件相互结合起来设计,大大提高了防雷组件的吸能效果,更好保证了乘员的安全。
