Description

Technical Field

[0001] This utility model relates to the field of automobile door manufacturing technology, and more particularly to a decorative panel on an automobile door panel. Background Technology

[0002] A Chinese utility model patent with application number CN201620412003.0, entitled "Automotive Door Panel Decorative Strip," discloses an automotive door panel decorative strip, including a decorative strip body. One long edge of the decorative strip body has a folded edge, and a mounting plate with through holes is provided on the short edge of the decorative strip body adjacent to the folded edge. The key feature is that the automotive door panel decorative strip also includes elastic clips and mounting seats for mounting the elastic clips. The mounting seats are vertically disposed on the inner end face of the folded edge and are integrally connected to the folded edge; the elastic clips are engaged with the mounting seats. This structure offers high assembly efficiency and ensures the flatness of the decorative strip body. However, the structural strength of this decorative strip is insufficient, the decorative pattern is easily worn, and its service life is short. Therefore, the structure of this decorative strip needs further improvement. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a decorative panel for automobile door panels that has a robust structure and a long service life for decorative patterns, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the decorative panel on the car door panel includes a panel body that can be fitted into the car door panel, a notch portion that can fit into the panel body is provided, and a decorative layer with a pattern is provided on the surface of the panel body. The panel body includes a decorative layer, an intermediate layer and a connecting layer. The decorative layer, intermediate layer and connecting layer are all injection-molded sheet structures. The decorative layer, intermediate layer and connecting layer are fused into an integral structure by high temperature. A connecting protrusion that can be connected to the car door panel is provided on the bottom surface of the connecting layer.

[0005] As an improvement, reinforcing ribs are preferably distributed laterally and vertically on the bottom surface of the connecting layer, with the laterally and vertically reinforcing ribs arranged alternately to increase structural strength.

[0006] In a further improvement, connecting seats may preferably be distributed on the bottom surface of the connecting layer, the connecting seats being connected to the reinforcing ribs, and the connecting protrusions being disposed on the connecting seats.

[0007] In a further improvement, the connecting layer, reinforcing ribs, connecting seat, and connecting protrusion can preferably be an integral structure formed by one-time injection molding.

[0008] As a further improvement, the connecting seat can preferably be a hollow structure that can reduce weight.

[0009] In a further improvement, the connecting protrusion can preferably be a hollow cylindrical structure, with reinforcing ribs spaced apart on its outer wall. This ensures a secure connection and convenient insertion.

[0010] As an improvement, a connecting layer protrusion that can be inserted into the car door panel can preferably be provided at one end of the bottom surface of the connecting layer, with the end of the connecting layer protrusion extending out of the end face of the panel. This facilitates connection.

[0011] In a further improvement, the protrusion of the connecting layer and the connecting layer can preferably be integrally manufactured.

[0012] As a further improvement, reinforcing ribs are preferably distributed at intervals on the protrusions of the connecting layer to enhance the connection strength between the protrusions and the connecting layer, thereby increasing structural strength.

[0013] As an improvement, a retaining ring can preferably be provided on the opening of the notch, and the retaining ring is connected to the reinforcing rib. This increases the structural strength.

[0014] Compared with existing technologies, the advantages of this utility model are as follows: The panel includes a decorative layer, an intermediate layer, and a connecting layer. All three layers are injection-molded sheet structures, and the decorative patterns are directly achieved using a plastic embossed structure, resulting in higher wear resistance and a longer service life compared to pigments or inks. The decorative layer, intermediate layer, and connecting layer are fused together at high temperature to form a single structure, increasing structural strength. The bottom surface of the connecting layer has connecting protrusions that allow it to connect to the car door panel, facilitating easy attachment to the door panel. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 7 As shown, the decorative panel on the car door panel of this embodiment includes a panel 1 that can be fitted onto the car door panel 2. A notch 11 for fitting a handle is provided on the panel 1. A patterned decorative layer is provided on the surface of the panel 1. The panel 1 includes a decorative layer 101, an intermediate layer 102, and a connecting layer 103. The decorative layer 101, intermediate layer 102, and connecting layer 103 are all injection-molded sheet structures. The decorative layer 101, intermediate layer 102, and connecting layer 103 are fused together at high temperature to form an integral structure. A connecting protrusion 12 for connecting to the car door panel 2 is provided on the bottom surface of the connecting layer 103. Reinforcing ribs 13 are distributed horizontally and vertically on the bottom surface of the connecting layer 103, with the horizontal and vertical reinforcing ribs arranged alternately.
