Lever compression energy absorption method and anti-collision pad structure
The invention provides a lever compression energy absorption method and an anti-collision pad structure. The anti-collision pad comprises an anti-collision pad body which can slide backwards to be compressed and absorb collision energy due to vehicle collision, and a lever structure arranged at the rear end of the anti-collision pad body. According to the anti-collision cushion, the lever principle is utilized, after the anti-collision cushion body is impacted to be completely compressed, the top end of the lever can be further stirred through the backward inclination deformation amount of the last section of frame, the bottom of the lever structure is inserted into the energy absorption buffering material, and impact energy is further absorbed by compressing the energy absorption buffering material. According to the lever structure, energy absorption buffer materials such as foamed aluminum can be invaded by vehicle collision to provide secondary energy absorption, and the energy absorption effect is better. When the anti-collision pad structure is used for protecting a 1.5-ton sedan car from collision at the speed of 100 km/h, the needed length of the anti-collision pad structure can be shortened to 4 m from 6 m, the reserved area needed by a buffering guide area is greatly compressed, and the anti-collision pad structure can be flexibly installed at the front ends of various flow guide areas to provide warning guide and TS-level protection.
本申请提供一种杠杆压缩吸能方法及防撞垫结构。其包括：能够由车辆撞击而向后滑移压缩吸收撞击能量的防撞垫主体，以及设置于防撞垫主体后端的杠杆结构。本申请利用杠杆原理，在防撞垫主体被撞击至完全压缩后，还能够进一步利用最后一节框架的后倾变形量拨动杠杆顶端，使得杠杆结构的底部插入吸能缓冲材料内，通过压缩吸能缓冲材料进一步吸收撞击能量。本申请的杠杆结构能够由车辆撞击而侵入泡沫铝等吸能缓冲材料提供二次吸能，吸能效果更好。采用本申请的防撞垫结构防护1.5吨小轿车100km/h速度碰撞时，防撞垫结构所需长度可由6m缩短至4m，大大压缩了缓冲引导区所需预留面积，能够灵活地安装在各类导流区域前端，提供警示引导以及TS级防护。
