The invention provides a pedestrian passive protection device, belongs to the technical field of automobile engineering, and particularly relates to to a pedestrian passive protection device. The pedestrian passive protection device comprises an engine hood body installed on a vehicle body through a movable hinge, wherein a U-shaped groove is formed in the lower side surface of the engine hood; the U-shaped groove divides the engine hood into a first-stage buffer area and a second-stage buffer area; a plurality of reinforcing plates are welded between the first-stage buffer area and the second-stage buffer area; and a top plate is firstly supported when a safety air curtain expands, the second-stage buffer area is further bent relative to the first-stage buffer area, so that a larger folded angle is bent, and a larger buffer space is provided. When a human body slides on the engine hood, speed reduction can be conducted by impacting the second-stage buffer area, the safety air curtainis located in front of the windshield after being filled with air, if the human body continues to slide, the safety air curtain can be impacted, serious injuries caused by the fact that the head of apedestrian impacts the front windshield are avoided, and the protection on the pedestrian can be greatly improved.
本发明提供了一种行人被动保护装置,属于汽车工程技术领域,汽车工程尤其涉及一种行人被动保护装置,包括通过活动铰链安装在车体上的发动机罩,所述发动机罩的下侧面开设有U型凹槽,U型凹槽将发动机罩分隔成一级缓冲区和二级缓冲区,一级缓冲区和二级缓冲区间焊接有多个加固板,安全气帘在膨胀时先将顶板撑起,使得二号缓冲区相对于一号缓冲区进行进一步的弯折,弯起更大的折角,具有更大的缓冲空间,通过当人体在发动机罩上滑行时,能够通过撞击二级缓冲区进行减速,安全气帘充满后会位于挡风玻璃的前方,人体如果继续滑动,可以撞击到安全气帘,避免行人的头部撞击到前挡风玻璃而造成严重的伤害,能够大大的提高对行人的保护。
