[0038] The reinforcing part is arranged as a thermoplastic resin part, and the reinforcing part is a reinforcing layer 110 or a reinforcing rib 120. Figure 1 As Figure 2 Indicated, the reinforcing part is the reinforcing layer 110; and as

[0039] Specifically, the reinforcing part can be a polypropylene part.

[0040] The main body 200 is set as a continuous fiber reinforced thermoplastic composite part, which includes an appearance part (not labeled in the figure), and the main body 200 is connected with the reinforcing part, and the appearance part is located on the back of the main body 200.

[0041] In the embodiment, the main body 200 is set as a continuous fiber reinforced thermoplastic composite part as the main body of the inner plate, which can significantly improve the dent resistance and overall performance of the door, increase the overall strength, and better improve the deformation problem caused by temperature change. The reinforcing part made of thermoplastic resin material is used for global reinforcement or local reinforcement of key parts such as hinges, limiters, door locks and the like.

[0042] As shown in Figure 1 , Figure 2 , on the basis of the above embodiment, the main body 200 and the reinforcing part are an integral injection molding part.

[0043] Generally, the inner door plate of the automobile is wrapped with leather, and the wrapped leather needs to be processed twice after injection molding, which is complex and high in cost.

[0044] In the embodiment, the main body 200 and the reinforcing part are integrally injection molded, without the need for secondary processing, which will not pollute the air in the car, and is convenient to manufacture.

[0045] As shown in Figure 1 , Figure 2 , on the basis of the above embodiment, the thickness of the reinforcing layer 110 is 1.5mm-3mm, and is specifically optimized to 2mm, and the thickness of the main body 200 is 1.5mm-2.5mm, and is optimized to 2mm.

[0046] As shown in Figure 1 , Figure 2 , on the basis of the above embodiment, the appearance part is a skin surface, and the main body 200 is formed into the skin surface by molding.

[0047] In the embodiment, the main body 200 and the reinforcing part are integrally injection molded, and the main body 200 is formed into the skin surface by molding in the process of integrally injection molding, so that appearance treatment is not needed.

[0048] As shown in Figure 3 , on the basis of the above embodiment, a transition part 300 is further included, the appearance part 400 is connected with the main body 200 through the transition part 300, the transition part 300 is set as a thermoplastic resin part, and the appearance part 400 is a paint spraying layer or a polyurethane part.

[0049] In the embodiment, the appearance part 400 can be divided into three forms, the first is that the appearance part 400 is a paint spraying layer, that is, corresponding color paint spraying treatment is directly performed on the surface of the transition part 300; the second is that the appearance part 400 is a polyurethane part, that is, a corresponding color polyurethane part is connected to the surface of the transition part 300, the thickness of the appearance part 400 is 50um-70um, and 60um is the best, and when the appearance part is the polyurethane part, the thickness is 0.2mm-0.7mm, and 0.5mm is the best, and the third appearance part 400 is a combination of the polyurethane part and the paint spraying layer, that is, a paint spraying layer is additionally arranged on the outer surface of the polyurethane part, and the problem of special color can be solved.

[0050] As shown in Figure 3 based on the above embodiment, the thickness of the reinforcing layer 110 is 1.5mm-3mm, and the thickness is optimized to 2mm, the thickness of the main body part 200 is 1.5mm-2.5mm, and the thickness is optimized to 2mm, and the thickness of the transition part 300 is 1.5mm-2mm.

[0051] As shown in Figure 4 based on the above embodiment, the reinforcing part is a reinforcing rib 120, the reinforcing rib 120 includes a plurality of reinforcing heads, the reinforcing head includes a connecting part 121, the connecting part 121 is connected with the main body part 200, and the thickness of the reinforcing rib is 3mm-8mm.

[0052] In the embodiment, the first reinforcing rib 120 is a structure of partially hollowing on the back of the main body part 200, which plays a role of local reinforcement and further reduces the weight.

[0053] As shown in Figure 5 based on the above embodiment, the reinforcing head further includes a protruding part 122, the protruding part 122 is integrally connected with the connecting part 121 and protrudes from the connecting part 121, and the connecting cross-sectional area of the connecting part 121 and the protruding part 122 is smaller than the connecting cross-sectional area of the connecting part 121 and the main body part 200.

[0054] In the embodiment, the protruding part 122 can play a role of reinforcing the inner plate, the connecting cross-sectional area of the connecting part 121 and the protruding part 122 is smaller than the connecting cross-sectional area of the connecting part 121 and the main body part 200, so that the connecting part 121 can increase the connecting strength of the reinforcing head and the main body part 200.

[0055] As shown in Figure 6 based on the above embodiment, the cross-sectional area of the connecting part 121 extending from the main body part 200 to the protruding part 122 gradually decreases.

[0056] In the present embodiment, the cross-sectional area of the connecting portion 121 gradually decreases from the main body portion 200 toward the protruding portion 122, and the portion where the total wall thickness of the inner plate is thick is reduced, thereby reducing the local surface indentation caused by the reinforcing rib 120.
