The engine hood comprises an outer plate and an inner plate, and a plurality of mounting positions with different strength requirements are arranged on one side of the outer plate; the inner plate comprises a plurality of inner plate units, the plurality of inner plate units correspond to the plurality of mounting positions one by one, each inner plate unit is mounted at the corresponding mounting position, and the plurality of inner plate units form a plate layer for improving the strength of the outer plate; the thickness of each inner plate unit is in direct proportion to the strength requirement of the corresponding installation position. The engine hood solves the problems that stress of the engine hood is not uniform, an existing engine hood is not subjected to reasonable structural design in combination with the stress characteristics of the engine hood, and therefore the weight of the engine hood cannot be reduced to the maximum extent, and cost cannot be reduced on the premise that effective work of the engine hood is guaranteed.

    本发明涉及一种发动机罩及汽车,其包括外板和内板,所述外板的一侧上具有不同强度需求的多个安装位置;所述内板包括多个内板单元,多个所述内板单元与多个所述安装位置一一对应,每个所述内板单元均安装于对应的所述安装位置处,多个所述内板单元形成一用以提高所述外板强度的板层,每个所述内板单元的厚度均与对应的所述安装位置处的强度需求呈正比;解决发动机罩的受力并非均匀的,现有的发动机罩并未结合其受力特点进行合理的结构设计,以致于发动机罩在保证有效工作的前提下,无法最大程度地减轻其重量及降低成本的问题。
