[0087] The present application discloses an engine hood inner plate assembly, and a corresponding engine hood comprising the inner plate assembly and an outer plate, the engine hood being connected with a hinge connecting arm assembly for fixing the engine hood;

[0088] The inner plate assembly and the outer plate are fixed with a lock reinforcing plate 2, an outer plate reinforcing plate 4 and a hinge reinforcing plate 3 for supporting the engine hood structure, which not only plays a supporting role in the space of the engine hood, but also strengthens the connection strength of the supporting components such as the hinge, the engine hood locking structure, etc.

[0089] The engine hood is made of aluminum alloy material. Among them, the outer plate is converted from 0.7mm steel plate to 0.95mm aluminum plate, the inner plate is converted from 0.55mm steel plate to 0.8mm aluminum plate, the lock reinforcing plate 2 is 1.2mm aluminum plate, the outer plate reinforcing plate 4 is 1.2mm aluminum plate, and the hinge reinforcing plate 3 is 1.5mm aluminum plate; while significantly reducing the weight of the engine hood, the stiffness can still meet the assembly performance of the engine hood through CAE simulation calculation and actual detection.

[0090] In order to further reduce the weight and increase the structural strength, the inner plate 1 is provided with a plurality of first weight reduction holes 104; the first weight reduction holes 104 are arranged in the area of the inner plate 1 between the lock reinforcing plate 2, the outer plate reinforcing plate 4 and the hinge reinforcing plate 3;

The support glue of the protruding first lightening hole 104 connects the inner and outer plate structure, not only can make the glue groove point more uniform, but also can support the inner and outer plate cavity well, and cooperate with the reinforcing plates to support the space of the inner and outer plates, so that the support points of the outer plate in the range of 200mm diameter are achieved. The overall stiffness and NVH first-order mode of the engine cover are greatly improved.

[0093] The support flange structure in the first lightening hole 104 at least includes the first support flange structure 101 and the outer plate reinforcing plate connecting strip 1011 abutting against the outer plate reinforcing plate 4, wherein the outer plate reinforcing plate connecting strip 1011 is arranged around the edge of the first support flange structure 101;
