The invention relates to an integrated pedestrian protection structure. The structure comprises a bumper skin, an energy absorption block and an anti-collision beam, the bumper skin is installed on anautomobile body, and a shank supporting cross beam is integrated at the lower end of the bumper skin; and the two ends of the shank supporting cross beam are fixedly connected with the anti-collisionbeam on the upper portion through side supporting supports, and the energy absorption block is fixedly arranged on the anti-collision beam. When a pedestrian collides with the front end of the automobile, the upper portions of the shanks of the pedestrian make contact with the middle of the bumper skin, energy is transmitted to the energy absorption block, the energy absorption block deforms to absorb the energy and then transmits impact to the anti-collision beam, the lower portions of the shanks of the pedestrian make contact with the lower portion of the bumper skin, the shank supporting cross beam integrated on the lower portion of the bumper skin absorbs collision energy, and the energy is transmitted to the anti-collision beam through the side supporting supports. Light weight is achieved, and impact energy on the lower portions of shanks of pedestrians can be effectively absorbed.

    本发明涉及一种集成式行人保护结构。该结构,包括保险杠蒙皮、吸能块和防撞梁,保险杠蒙皮安装在车身上,下端集成小腿支撑横梁;小腿支撑横梁两端通过侧支撑支架与上部的防撞梁固定连接,所述吸能块固定设置在防撞梁上;行人与车辆前端碰撞时,行人的小腿上部与所述保险杠蒙皮中部接触,将能量传递到所述吸能块上,所述吸能块变形吸收能量后再将冲击传递到防撞梁上;行人的小腿下部与所述保险杠蒙皮下部接触,所述保险杠蒙皮下部集成的小腿支撑横梁吸收碰撞能量,通过侧支撑支架将能量传递至防撞梁上。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。
