Abstract

The invention discloses a hinge device used for an engine cover, a pedestrian head protection system and a vehicle. The hinge device used for the engine cover comprises a support arm, a first connecting rod, a second connecting rod and a jacking device. The support arm is suitably connected with the engine cover. One end of the first connecting rod is suitably hinged onto a vehicle body. One end of the second connecting rod, the other end of the first connecting rod and the support arm are connected in a hinged manner. The other end of the second connecting rod is suitably connected with the vehicle body in a slidable manner. The jacking device is used for selectively hoisting the support arm. When the jacking device is triggered, the jacking device upwardly jacks the support arm. The other end of the second connecting rod moves towards the first direction in order to hoist the engine cover. When the jacking device is not triggered and the engine cover is subjected to downward pressure, the second connecting rod moves towards the second direction in order to descend the engine cover. The hinge device used for the engine cover is integrated with active protection and passive protection. Therefore, the protection effect is exerted on a head of a pedestrian. Additionally, the hinge device is simple in structure and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, and in particular relates to a hinge device for an engine cover, a pedestrian head protection system with the hinge device and a vehicle. Background technique [0002] In a traffic accident where a vehicle collides with a pedestrian, the pedestrians outside the vehicle are obviously at a disadvantage. The pedestrian protection performance of the vehicle is becoming more and more important, and it directly affects the safety rating of the vehicle. In related technologies, the protection of pedestrians' lower legs is often optimized and improved, and there is little research on the protection of pedestrians' heads, and there is room for improvement. Contents of the invention [0003] In view of this, the present invention aims to provide a hinge device for the engine hood to improve the head protection of pedestrians. [0004] In order to achieve the above object, technical solution of th...
