The invention discloses an engine hood inner plate assembly, an engine hood and an automobile. The engine hood inner plate assembly comprises an inner plate, a lock reinforcing plate, an outer plate reinforcing plate and a hinge reinforcing plate. The lock reinforcing plate is connected to the upper surface of the first edge of the inner plate; the outer plate reinforcing plate is connected to the upper surface of the second edge of the inner plate; the hinge reinforcing plates are connected to the upper surfaces of the inner plates on the two sides of the outer plate reinforcing plate; and the first edge and the second edge of the inner plate are oppositely arranged. The inner plate comprises a plurality of first lightening holes; the first lightening hole is formed in an inner plate area among the lock reinforcing plate, the outer plate reinforcing plate and the hinge reinforcing plate; the lightweight design of an automobile is achieved, the reinforcing plate is arranged between the inner plate and the outer plate, so that the strength of the space and the connecting structure of the inner plate and the outer plate is improved, the performance requirement of the engine hood is met, the weight is remarkably reduced, and the optimal weight reduction effect is achieved when aluminum materials are adopted.

    本发明公开了一种发动机罩内板总成、发动机罩及汽车,所述发动机罩内板总成包括内板,及锁加强板、外板加强板和铰链加强板;锁加强板连接在所述内板的第一边缘上表面;外板加强板连接在所述内板的第二边缘上表面;铰链加强板连接在所述外板加强板两侧的所述内板的上表面;所述内板的第一边缘与第二边缘相对设置。所述内板包括多个第一减重孔;所述第一减重孔开设在锁加强板、外板加强板和铰链加强板之间的内板区域;本发明实现了汽车轻量化设计,通过在内外板间设置加强板,使得内外板空间及连接结构强度得到提升,满足发动机罩自身性能要求,并显著降低了重量,采用铝制材料时,同时达到最优的减重效果。
