Combined with integrated optical lighting design, large areas of the interior decorative surfaces, including door panels, sub-instrument panels and instrument panels, door panel trim strips, sunroof, doors, and door handles, are illuminated to meet the user's pursuit of visual experience.
[0003] Existing automotive trim components include a translucent substrate and a light-emitting component. The outer surface of the translucent substrate is provided with a decorative layer, and the pattern of the decorative layer is displayed when the light-emitting component emits light, thus achieving a decorative effect. However, most of these decorative layers are single-layer structures, with a monotonous form, poor decorative effect, poor user experience, and unattractive appearance. They fail to meet user experience requirements and have a limited range of applications.
[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an automotive exterior shell structure. Through the design of the shell's various layers, the hollow areas and hollow patterns of the shell can display different colors when the lighting components are turned on or off. This achieves not only the exterior decoration function of the car but also the dual enhancement of multiple luminous color effects, resulting in better decorative and aesthetic effects and satisfying the user's experience.

The light-shielding layer, the polyurethane paint layer, the light-transmitting layer, the printing layer, and the transparent injection molding layer are arranged sequentially from the inside to the outside on the other side of the substrate layer. The substrate layer has a hollow area and a hollow pattern. The hollow area and the hollow pattern penetrate the light-shielding layer, the polyurethane paint layer, the light-transmitting layer, and the printing layer. The color layer is disposed on the hollow area. The PVD coating layer is disposed on the hollow pattern. The light component is disposed on the other side of the substrate layer, and the light source of the light component is oriented towards the hollow area and the hollow pattern.
[0007] As a preferred embodiment, the semi-transparent matte layer, the light-transmitting color layer, and the light-transmitting layer are all made of polyurethane.
[0008] As a preferred embodiment, the light-transmitting color layer is a black or other color light-transmitting color layer structure.
[0009] As a preferred embodiment, the light-shielding layer is a non-transparent light-shielding layer of dark polyurethane.
[0010] As a preferred embodiment, the color layer is a blue, orange, or other colored coating.
[0011] As a preferred embodiment, the polyurethane coating layer consists of two layers arranged sequentially from the inside out.
[0012] As a preferred embodiment, the inner polyurethane paint layer is black, while the outer polyurethane paint layer is of other colors.

[0020] Please refer to Figures 1 to 2 As shown, it illustrates the specific structure of an embodiment of the present invention.
[0021] An automotive exterior shell structure includes a shell 10 and a lighting assembly 20; wherein: The housing 10 includes a substrate layer 11, a semi-transparent matte layer 12, a light-transmitting color layer 13, a light-shielding layer 14, a color layer 15, a polyurethane paint layer 16, a PVD coating layer 17, a light-transmitting layer 18, a printing layer 19, and a transparent injection-molded layer 110. The substrate layer 11 is a transparent substrate layer. The semi-transparent matte layer 12 and the light-transmitting color layer 13 are sequentially disposed on one side of the substrate layer 11 from the outside to the inside. The light-shielding layer 14, the polyurethane paint layer 16, the light-transmitting layer 18, the printing layer 19, and the transparent injection-molded layer 110 are sequentially disposed from the inside to the outside. The substrate layer 11 is disposed on the other side of the substrate layer 11. The substrate layer 11 has a hollow area 101 and a hollow pattern 102. The hollow area 101 and the hollow pattern 102 both penetrate the light-shielding layer 14, the polyurethane paint layer 16, the light-transmitting layer 18, and the printing layer 19. The color layer 15 is disposed on the hollow area 101. The PVD coating layer 17 is disposed on the hollow pattern 102. The light component 20 is disposed on the other side of the substrate layer 11. The light source of the light component 20 is oriented towards the hollow area 101 and the hollow pattern 102. Specifically, the semi-transparent matte layer 12, the light-transmitting color layer 13, and the light-transmitting layer 18 are all made of polyurethane. The light-transmitting color layer 13 is a black or other colored light-transmitting layer structure. The light-shielding layer 14 is a dark polyurethane non-transparent light-shielding layer. The color layer 15 is a blue, orange, or other colored coating. The PVD coating 17 is a chromium metal coating. The transparent injection molding layer 110 is a polycarbonate injection molding layer. Thus, through the design of each layer of the shell, the hollow areas and hollow patterns of the shell can display different colors when the light components are turned on and off. This achieves the dual benefits of not only the exterior decoration function of the car but also multiple luminous color effects. Furthermore, it can be designed and used with different colored semi-transparent matte layers, light-transmitting color layers, and light-transmitting layers according to the user's needs, resulting in better decorative and aesthetic effects, satisfying the user experience, and having a wide range of applications.
[0022] Furthermore, the polyurethane paint layer 16 is provided in two layers arranged sequentially from the inside out. The inner polyurethane paint layer 16 is black, and the outer polyurethane paint layer 16 is a polyurethane paint layer of other colors. Preferably, the thickness of the two polyurethane paint layers 16 is equal or unequal. Thus, the arrangement of the two polyurethane paint layers has, on the one hand, better weather resistance and excellent glossy black appearance, improving the service life of the housing; on the other hand, it has high reflectivity, which can play a role in reflecting and cooling, reducing the impact of heat generated by the lighting components on the housing during use, and ensuring the stable use of the product.
[0023] The key design feature of this utility model is that, through the structural design of each layer of the shell, the hollowed-out area and hollowed-out pattern of the shell can display different colors when the light component is turned on or off. This not only achieves the function of decorating the car's exterior but also provides a variety of luminous color effects, resulting in better decorative and aesthetic effects, satisfying the user experience, and having a wide range of applications.
[0024] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
