Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automotive exterior trim part that can display a bright white color when the light source is emitting light and a high-brightness dual color when the light source is not emitting light. Background Technology

[0002] One existing type of personalized automotive exterior trim includes, from the inside out, a light source layer, a dark light-blocking coating, a light-transmitting material, a light-transmitting primer layer, a light-transmitting topcoat layer, and a light-transmitting clear coat layer. The desired pattern is engraved on the dark light-blocking coating. Because the light-transmitting material, primer, topcoat, and clear coat layers are all transparent coatings and materials, the desired pattern shines through the surface of the exterior trim, achieving an luminous effect. This allows for customization of different patterns to achieve a personalized appearance. However, this type of exterior trim only reflects the color of the pattern based on the color of the light source layer. To obtain different pattern colors, different light sources must be used. Furthermore, the pattern cannot emit bright colors under light from the light source layer, and the overall pattern is somewhat blurry and lacks clarity. The color stability and conversion accuracy also need optimization. Utility Model Content

[0003] The problem this invention aims to solve is to provide a dual-color, hidden, and variable luminous personalized exterior accessory, thereby addressing the issue that existing personalized exterior accessories cannot display bright colors in the absence of a light source.

[0004] To solve the above problems, the technical solution of this utility model is as follows: This dual-color hidden variable luminous personalized exterior part includes, from the inside out, a light source layer, a light-transmitting material support layer, a color difference control layer, a dark light-shielding coating, and a light-transmitting clear varnish layer. The dark light-shielding coating is the pattern layer after the pattern to be displayed is peeled off, and the black of the dark light-shielding coating is a high-gloss black. The color difference control layer includes a light-transmitting primer paint layer and a light-transmitting color layer. The light-transmitting material support layer is a layer of transparent primer coated on the surface of the light-transmitting material.

[0005] A more specific embodiment of the above technical solution is that the light-transmitting material of the light-transmitting material support layer is PP material.

[0006] Furthermore: the light-transmitting material of the light-transmitting material support layer is ABS material.

[0007] Furthermore, the color layer of the color difference control layer is light blue or light purple.

[0008] Furthermore, the light source layer is an LED light source layer or an RGB light source layer.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0010] 1. The processing method for creating a dual-color, hidden, variable, luminous personalized exterior trim involves spraying a color difference control layer directly onto a light-transmitting material support layer, spraying a dark light-shielding coating onto the outer side of the color difference control layer, and engraving a pattern on the dark light-shielding coating. Then, the dark light-shielding coating outside the pattern is peeled off. This results in visible surface colors (i.e., the pattern of the color layer in the color difference control layer and the high-gloss black of the car body) when the light source layer is not emitting light, forming a dual-color dazzling decorative part that fully showcases the car's gorgeous appearance. When the light source layer is emitting light, the surface pattern changes from the color of the color difference control layer, such as blue, to the pattern of the light source light color (such as white or other seven colors formed by each RGB light of the light source layer using different colors) to create a luminous pattern or other seven-color dazzling effects.

[0011] 2. The color difference control layer of this dual-color hidden variable luminous personalized exterior trim consists of two layers: a translucent primer paint layer and a color layer. The color layer controls the color displayed when the light source layer is on, while the translucent primer paint layer controls the film thickness of the color difference control layer. Combined with the use of a translucent clear coat layer, the exterior trim is treated with weather resistance, achieving weather resistance under various complex climate conditions and meeting automotive-grade requirements. It also ensures that the pattern color matches the body color, while increasing the visual decorative effect and interactive lighting function. Based on the existing hidden luminous technology, it enhances the visual integration and body-color matching appearance requirements. Attached Figure Description

[0013] The diagram shows: 1. Light source layer, 2. Transparent material support layer, 3. Color difference control layer, 4. Dark light-blocking coating, 5. Transparent varnish layer. Detailed Implementation

[0014] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0015] like Figure 1 The illustrated dual-color, concealable, and customizable luminous exterior component comprises, from the inside out, a light source layer 1, a translucent material support layer 2, a color difference control layer 3, a dark light-shielding coating 4, and a translucent clear coat layer 5. The light source layer 1 is an LED light source layer or an RGB light source layer. The translucent material support layer 2 is a PP material surface coated with a transparent primer; in other embodiments, it can also be an ABS material surface coated with a transparent primer, specifically a transparent gray primer.

[0016] The color layer of color difference control layer 3 is light blue or light purple. The color layer controls the color displayed when the light source layer is bright. The translucent primer paint layer can control the film thickness of the color difference control layer.

[0017] The dark opaque coating 4 is the pattern layer that has been peeled off from the pattern that needs to be displayed after being sculpted. The black of the dark opaque coating is a high-gloss black. The color difference control layer 3 includes a translucent primer paint layer and a translucent color layer.

[0018] This processing method for creating dual-color, hidden, variable, luminous personalized exterior parts involves spraying a color difference control layer directly onto a light-transmitting material support layer, spraying a dark light-shielding coating onto the outer side of the color difference control layer, and engraving a pattern on the dark light-shielding coating. Then, the portion of the dark light-shielding coating outside the pattern is peeled off. This results in a visible surface color (i.e., the pattern of the color layer in the color difference control layer and the high-gloss black of the car body) visible when the light source layer is not emitting light, forming a dual-color dazzling decorative part that fully showcases the car's stunning appearance. When the light source layer emits light, the surface pattern changes from the color of the color difference control layer (e.g., blue) to the pattern of the light source light color (e.g., white, or other seven-color patterns formed by each RGB light in the light source layer using different colors), creating a luminous pattern or other seven-color dazzling effects.

[0019] Processing methods include:

[0020] Translucent materials are produced using molds. A transparent gray primer is sprayed onto the surface of the transparent translucent material to form a translucent material support layer 2. On the side of the translucent material support layer 2 with the transparent gray primer, a layer of translucent primer and a layer of translucent color (light blue, light purple, etc.) are sprayed one after the other, i.e., color difference control layer 3. After baking, a layer of dark opaque topcoat (here, the dark color is high-gloss black) is applied, i.e., dark opaque coating layer 4. Then, a non-translucent dark opaque coating layer 4 is sprayed, and a carving robot is used to carve the pattern layer by layer. After the high-gloss dark opaque coating layer 4 outside the pattern is peeled off, the pattern and graphics of color difference control layer 3 are highlighted. Finally, a protective clear coat is sprayed on the line, i.e., translucent clear coat layer 5. After baking on the painting line, the weather resistance performance requirements of mass-producible products and automotive-grade requirements are met, and a two-color appearance effect is achieved when not emitting light. A light-emitting unit, namely the light source layer 1, is installed on the side of the translucent material (i.e., the translucent material support layer 2) that is not coated with transparent primer. The light-emitting unit is an LED tube for light distribution and color processing. When the LED tube is turned on, the emitted light passes through the engraved pattern and graphics, then through the transparent material, and finally through the translucent paint layer, ultimately forming a pattern of the light source layer's color (such as white light or other colors or colors) on the surface of the material, thus achieving the effect of changing the appearance and function of light emission. When the light source is turned off, it is a high-brightness dual-color dazzling display effect, that is, the high-brightness black of the car body outside the pattern and the color difference control layer color such as light blue displayed in the pattern.

[0021] This illuminated personalized exterior accessory retains the performance of automotive exterior accessories while achieving a personalized appearance, meeting different human-computer interaction needs and a seven-color changing appearance effect.
