The invention relates to the technical field of vehicles, in particular to a vehicle and a front wall upper cover plate assembly thereof, and aims to solve the problems of overlong development period, high cost and even high possibility of mistaken explosion in a scheme for reducing injury to pedestrians in a collision accident by adopting an active engine cover technology in the conventional vehicle. In order to achieve the purpose, the front wall upper cover plate assembly comprises a rear plate and a front plate structure, the front plate structure comprises a first top plate, a first vertical plate and a first bottom plate, and the front edge of the first top plate and the front edge of the first bottom plate are connected with the upper edge and the lower edge of the first vertical plate correspondingly; the rear edge of the first top plate and the rear edge of the first bottom plate are both connected with the rear plate, so that the rear plate and the front plate structure define a cavity, a first collapse hole is formed in the first top plate, and a second collapse hole is formed in the first vertical plate. Through the arrangement, the damage to pedestrians in a pedestrian-vehicle collision accident is reduced, the number of used materials is small, the weight is light, the development period is short, and the cost is low.
本发明涉及车辆技术领域,具体提供一种车辆及其前围上盖板总成,旨在解决现有车辆采用主动式发盖技术来降低碰撞事故中对行人的伤害的方案存在开发周期过长、成本高昂甚至容易发生误爆的问题。为此目的,本发明的前围上盖板总成包括后板以及前板结构,前板结构包括第一顶板、第一竖板和第一底板,第一顶板的前边缘和所述第一底板的前边缘分别与第一竖板的上边缘和下边缘连接,第一顶板的后边缘和第一底板的后边缘均与后板连接,从而使得后板和前板结构围成空腔,第一顶板上形成有第一溃缩孔,第一竖板上形成有第二溃缩孔。通过这样的设置,减小了人车碰撞事故中对行人的伤害,使用材料较少,重量较轻,开发周期较短,成本较低。
