The invention discloses a crushable energy absorption type non-metal front hatch cover and a vehicle, the front hatch cover comprises a front hatch cover outer plate and a front hatch cover inner plate which are made of non-metal, the front hatch cover outer plate and the front hatch cover inner plate are buckled and fixed, a cavity is formed between the front hatch cover outer plate and the front hatch cover inner plate, and the cavity is filled with foaming filler. According to the vehicle and the crushable energy absorption type non-metal front hatch cover, the space between the front hatch cover outer plate and the front hatch cover inner plate is filled with the foaming filler, the foaming filler has the continuous and stable crushing energy absorption effect, and when the vehicle collides with pedestrians, the foaming filler can be responsible for stable and controllable crushing deformation, collision energy absorption and head deceleration reduction; and head collision injury is reduced, so that the purpose of protecting pedestrians is achieved. And the effects of enhancing local anti-sinking performance, insulating sound and reducing noise are achieved. And the non-metal front hatch cover also has the characteristics of low density and light weight.
本发明公开一种可压溃吸能式非金属前舱盖和车辆,前舱盖包括非金属制成的前舱盖外板和前舱盖内板,所述前舱盖外板和所述前舱盖内板扣合固定,且二者之间形成有空腔,所述空腔内填充有发泡填充物。所提供的车辆和可压溃吸能式非金属前舱盖,在前舱盖外板和前舱盖内板之间填充有发泡填充物,发泡填充物具有可持续稳定压溃吸能的作用,当与行人发生碰撞工况时,可负责发生稳定可控的压溃变形,吸收碰撞能量,降低头部减速度,减小头部碰撞伤害,从而达到保护行人的目的。而且具有增强局部抗凹性能、隔音降噪的作用。非金属的前舱盖也具有密度小,重量轻的特点。
