Description

一种发动机盖铰链及汽车 技术领域
本申请涉及汽车发动机盖，具体公开了一种发动机盖铰链及汽车。
背景技术
据统计，近年来中国每年死于交通事故的行人超过2万人，约占总交通事故死亡人数的30％。欧盟统计的道路交通事故中，行人死亡数是车内乘员的9倍。并且调查显示，在行人与车辆撞击的交通事故中，因头部撞击导致死亡的人数占据很大的比例，当车辆与行人发生碰撞时，在车辆与行人的腿部发生碰撞后，行人容易以腿部为中心撞向车头，而行人头部容易砸到发动机舱盖板末端。
但是由于目前设置于发动机盖上的铰链垂直刚度过大，在汽车与行人相碰时，该种发动机盖铰链无法实现溃缩，导致发动机舱盖难以变形，即无法吸收碰撞能量，这样对行人的伤害程度很大。
