The invention provides an engine hood of a vehicle. The engine hood of the vehicle comprises an engine hood outer plate and an engine hood inner plate, the engine hood outer plate covers the engine hood inner plate, the engine hood inner plate comprises a peripheral ring beam, the peripheral ring beam is provided with an inner plate rear beam, an inner plate front beam and two inner plate side beams, the two inner plate side beams are connected between the inner plate rear beam and the inner plate front beam, a hollow area is jointly defined by the two inner plate side beams, the inner plate rear beam and the inner plate front beam, and the sections of the inner plate side beams, the inner plate rear beam and the inner plate front beam are different. Therefore, through cooperation of the engine hood outer plate and the engine hood inner plate, the effective hollowed-out area of the engine hood can be increased, pedestrians can be protected, the weight of the engine hood can be reduced,the lightweight design of the engine hood can be achieved, and meanwhile the structural strength of the engine hood can be guaranteed.
本发明提供了一种车辆的发动机罩,车辆的发动机罩包括:发动机罩外板和发动机罩内板,所述发动机罩外板罩设于所述发动机罩内板,所述发动机罩内板包括:周圈梁,所述周圈梁具有内板后梁、内板前梁和两个内板边梁,两个所述内板边梁连接在所述内板后梁和所述内板前梁之间,两个所述内板边梁、所述内板后梁和所述内板前梁共同围成中空区域,所述内板边梁、所述内板后梁和所述内板前梁的截面不同。由此,通过发动机罩外板和发动机罩内板配合,能够增加发动机罩的有效镂空面积,有利于对行人的保护,并且,也能够减小发动机罩的重量,可以实现发动机罩的轻量化设计,同时,也可以保证发动机罩的结构强度。
