The invention belongs to the field of vehicles, and particularly relates to a vehicle passenger lightning protection lower limb protection device. The device comprises a lower limb protection device upper plate, a main supporting plate, an auxiliary supporting plate and a lower limb protection device lower plate; a plurality of parallel clamping grooves are uniformly distributed in the lower surface of the lower limb protection device upper plate; the main supporting plate comprises two parts with the included angle of 120 degrees, the width of the wide plate is equal to that of the auxiliarysupporting plate, one end of the main supporting plate and one end of the auxiliary supporting plate are fixedly connected with the lower limb protection device lower plate, and the intersection of the auxiliary supporting plate and the main supporting plate is fixedly connected to form an equilateral triangle to form an energy absorption subunit. The plurality of energy absorption subunits are adjacently arranged in parallel; the narrow plate of each main supporting plate is clamped into the clamping groove of the lower limb protection device upper plate to be connected with the lower limb protection device upper plate. The energy absorption subunit formed by the main supporting plate, the auxiliary supporting plate and the lower limb protection device upper plate with the clamping grooveis adopted, after the energy absorption subunit is impacted by explosion, the shank posture of a passenger is changed, and injuries to the passenger are reduced.

    本发明属于车辆领域,具体涉及一种车辆乘员防雷下肢保护装置。包括下肢保护装置上板,主支撑板,副支撑板和下肢保护装置下板;下肢保护装置上板下表面均布有多个平行设置的卡槽;主支撑板包括夹角为120°的两部分,其中宽板的宽度等于副支撑板的宽度,主支撑板和副支撑板的一端与下肢保护装置下板固定连接,副支撑板和主支撑板的两部分的交汇处固定连接形成等边三角形,形成一个吸能子单元,多个吸能子单元相邻平行设置;每一个主支撑板的窄板通过卡入下肢保护装置上板的卡槽实现与下肢保护装置上板的连接。本申请采用了主支撑板、副支撑板和带有卡槽的下肢保护装置上板形成的吸能子单元,受到爆炸冲击后,改变乘员小腿姿势,降低乘员的损伤。
