The invention relates to a leg lightning protection device and a vehicle. The leg lightning protection device comprises a top plate, a bottom plate and an energy absorption layer. The top plate is used for bearing feet; the bottom plate and the top plate are oppositely arranged in the first direction. The energy absorption layer is arranged between the top plate and the bottom plate, the energy absorption layer comprises a plurality of energy absorption units which are arranged in an array at intervals, and each energy absorption unit comprises a body and an energy absorption cavity formed in the body. When the leg lightning protection device is subjected to environmental impact such as explosion, impact force is not transmitted to the feet and the legs of the human body immediately but transmitted to the energy absorption unit through the bottom plate, and impact energy is dispersed and consumed through deformation of the body and compression of gas in the energy absorption cavity. On one hand, the time for transmitting impact energy to the feet and the legs of the human body can be delayed, on the other hand, the impact force transmitted to the legs and the feet of the human body can be reduced, the impact value borne by the feet and the legs of the human body is smaller than the damage bearing limit of the human body, and the purpose of protecting the feet and the legs of the human body is achieved.

    本申请涉及一种腿部防雷保护装置及车辆,腿部防雷保护装置包括顶板、底板和吸能层;顶板用于承载脚部;底板与顶板沿第一方向相对设置;吸能层设置于顶板和底板之间,吸能层包括多个呈阵列排布且间隔设置的吸能单元,吸能单元包括本体和设置于本体内部的吸能腔室。当腿部防雷防护装置遭受爆炸等环境冲击时,冲击力不会立即传递至人体脚部和腿部,而是通过底板传递至吸能单元,利用本体的变形和吸能腔室内气体的压缩对冲击能进行分散和消耗,一方面,可以延迟冲击能传递至人体脚部和腿部的时间,另一方面,可以降低传递至人体腿部和脚部的冲击力度,使人体脚部和腿部所受冲击值小于人体损伤承受极限,达到保护人体脚部和腿部的目的。
