The invention discloses an energy absorption type aluminum alloy engine hood structure which comprises an engine hood outer plate (1) and an engine hood inner plate (2), a plurality of energy absorption mechanisms (8) are punched at the bottom of the engine hood inner plate (2), each energy absorption mechanism (8) comprises an upper boss and a lower boss, and a deformation guide groove mechanism is formed in the connecting position of each upper boss and the corresponding lower boss. The top of the upper boss is connected with the engine hood outer plate (1), and a through hole is machined in the top of the upper boss. The edge of the engine hood outer plate (1) is connected with the edge of the engine hood inner plate (2) in a closed mode, and the energy absorption mechanisms (8) are all located between the engine hood outer plate (1) and the engine hood inner plate (2). According to the aluminum alloy engine hood, impact energy is absorbed by guiding full deformation of the two-stage step structure, the collision energy absorption performance of the aluminum alloy engine hood is improved, the injury value to the head of a collided person is obviously reduced, and the protection performance of the aluminum alloy engine hood to pedestrians is effectively improved.
本发明公开了一种吸能型铝合金发动机罩的结构,包括发动机罩外板(1)、发动机罩内板(2),发动机罩内板(2)的底部冲压多个吸能机构(8),吸能机构(8)包括上凸台和下凸台,上凸台与下凸台的连接处形成变形引导槽机构,上凸台的顶部与发动机罩外板(1)连接,上凸台的顶部加工有通孔;发动机罩外板(1)的边缘与发动机罩内板(2)的边缘闭合连接,多个吸能机构(8)均位于发动机罩外板(1)与发动机罩内板(2)之间。本发明通过引导两级台阶结构的充分变形来吸收冲击能量,提高了铝合金发动机罩的碰撞吸能性,对被碰撞人的头部伤害值明显降低,本发明有效提升了铝合金发动机罩对行人的保护性能。
