The invention relates to a pedestrian protection leg type protection integrated structure. The protection integrated structure comprises a lower protection plate, an energy absorption block and an anti-collision beam, the lower protection plate is installed between a front end frame and a front bumper skin, the two ends of the lower protection plate are connected with the anti-collision beam through side supporting supports, the anti-collision beam is connected with a longitudinal beam, and the energy absorption block is fixed to the anti-collision beam. A shank supporting cross beam is integrated on the lower protection plate, and part of collision energy on the lower portion of the shank is transmitted to the side supporting supports through the shank supporting cross beam and then transmitted to a vehicle body through the front anti-collision beam; and part of collision energy is transmitted to the front end frame through the lower protection plate and then transmitted to the longitudinal beam. The lower protection plate is connected with a lower cross beam of the front end frame, and a gap between a front bumper and the bottom of the front end frame is sealed. Light weight is achieved, impact energy on the lower portions of shanks of pedestrians can be effectively absorbed, the number of parts is reduced, cost is reduced, the modality of the whole front end is improved, andimprovement of NVH is facilitated.
本发明涉及一种行人保护腿型防护集成结构。该防护集成结构,包括下护板、吸能块和防撞梁,下护板安装在前端框架和前保险杠蒙皮之间,下护板两端通过侧支撑支架与防撞梁连接,防撞梁与纵梁连接,吸能块固定在防撞梁上。下护板集成了小腿支撑横梁,小腿下部的碰撞能量一部分通过小腿支撑横梁传递到侧支撑支架上,再通过前防撞梁传递到车身上;一部分碰撞能量通过下护板传递到前端框架上,再传递到纵梁上。下护板与前端框架的下横梁连接,封闭了前保险杠与前端框架底部的空隙。本发明即实现了轻量化,又可以有效吸收行人小腿下部的冲击能量,减少了零件数量,降低了成本,整个前端的模态也得到了提升,有利于NVH的提升。
