In this way, different patterns can be customized according to personal preferences to achieve personalized appearance characteristics. However, this type of exterior can only display one pattern after customization, and the coating structure is relatively complex, resulting in a blurred overall pattern, insufficient clarity, and the color stability conversion accuracy needs to be optimized.

BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 is a front view of an embodiment of the present invention; Markings in the figure: light source layer 1, light-transmitting material support layer 2, black body light-shielding coating layer 3, color difference control layer 4, light-transmitting varnish layer 5. DETAILED DESCRIPTION
[0011] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings: like Figure 1 The light-individualized exterior trim that can realize parametric pattern changes shown in the figure includes, from inside to outside, a light source layer 1, a translucent material support layer 2, a black body light-shielding coating 3, a color difference control layer 4 and a translucent varnish layer 5; the black body light-shielding coating 3 includes a non-translucent black light-shielding paint layer and a color layer (the color of the color layer can be the same color as the body, or other colors different from the body), the black body light-shielding coating 3 is a microporous layer with an aperture between 0.05mm-0.2mm, the black body light-shielding coating 3 is engraved with a pattern to be displayed, and the pattern of the black body light-shielding coating is a matrix composed of origins or square points of 0.2mm-0.3mm, and the spacing between every two origins or square points is 0.2mm-0.9mm. By carving out extremely small origin square dot matrix patterns on the black car body light-shielding coating, different patterns can be achieved by using different parameter settings, thus realizing personalized pattern exterior decoration; the black car body light-shielding coating is carved into a microporous layer, which increases the light transmittance by about 30%, improves the light source utilization rate, and reduces the total power cost of the light source electronic module by 30%, while meeting the visual requirements of the overall car body color integrity requirements.
[0012] The light-transmitting material support layer 2 is a PP material surface coated with a light-shielding primer, wherein the light-shielding primer is a light-shielding gray-black primer; the color difference control layer 4 is a light-transmitting light-shielding layer of the same color as the vehicle body, and the thickness of the color difference control layer is 10um-20um; the light source layer 1 is an LED light source layer.
[0013] Processing methods include: A light-transmitting material is produced by using a mold, and a light-shielding gray-black primer is sprayed on the surface of the transparent light-transmitting material to form a light-transmitting material support layer 2. A layer of non-light-transmitting black light-shielding paint layer and a layer of color layer are successively sprayed on the side of the light-transmitting material support layer 2 sprayed with the light-shielding gray-black primer to form a black body light-shielding coating layer 3, and then an engraving robot is used to engrave 0.2mm-0.3mm origins or square points with a spacing of 0.2mm-0.9mm on the non-light-transmitting black light-shielding paint layer and the color layer. According to human vision, it is indistinguishable at this size. Through matrix parameterization, the pattern matrix can form different patterns and graphics under different parameter control (such as different origins or square points in different rows and columns in the matrix can form different patterns), achieving visual consistency. Body color effect; while carving into a pattern, 0.05mm-0.2mm micropores are also carved out in the pattern and non-pattern parts to form a microporous layer, which increases light transmittance by about 30%, improves light source utilization, and reduces the total power cost of the light source electronic module by 30%; after the surface is cleaned, a light-transmitting light-colored paint (thickness of 10um-20um) similar to the body color is sprayed, that is, the color difference control layer 4, to achieve a high-transmittance color layer. This layer achieves a more real and refined appearance decoration with visual integration, while reducing light blocking, providing light transmittance, and can well cover the microporous frame, weakening the microporous color difference, achieving the effect of maintaining consistency with the body color, and at the same time weakening the touch step difference; after the coating line is baked, a layer of transparent varnish (that is, translucent varnish layer 5) is finally sprayed to provide weather protection for the product to achieve various weather resistance conditions of the product and meet the requirements of vehicle regulations. A light-emitting unit (light source layer 1), i.e., a luminous LED lamp, is installed in front of the pattern of the black car body light-shielding coating 3 on the side of the light-transmitting material support layer 2 that is not sprayed with the light-shielding gray-black primer. When the LED lamp is turned on, light is emitted through the engraved patterns and graphics, then through the transparent material, and finally through the light-transmitting paint layer (i.e., the color difference control layer 4, the light-transmitting varnish layer 5), and finally a pattern is formed on the surface of the material to achieve the effect and function of luminous appearance.
[0014] The method realizes light-transmitting exterior trim, which not only retains the performance of the automobile exterior trim, but also realizes the appearance characteristics of personalized pattern changes to meet the needs of different customers.
