Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to an automobile exterior decoration part with a hidden light source capable of realizing parameter changes to obtain different personalized patterns and adjusting color difference through micropores. Background Art

[0002] Existing automotive exterior trims with personalized patterns include, from the inside out, a light source layer, a black body light-shielding coating, a translucent material, a translucent primer layer, a translucent topcoat layer, and a translucent clearcoat layer. The desired pattern is engraved on the black body light-shielding coating. Because the translucent material, the translucent primer layer, the translucent topcoat layer, and the translucent clearcoat layer are all transparent coatings and materials, the desired pattern is visible on the exterior trim surface, creating a luminous effect and functional appearance. This allows for customized patterns based on personal preferences, achieving a personalized appearance. However, this type of exterior trim can only display one pattern after customization, and the coating structure is relatively complex, resulting in a blurred overall pattern and insufficient clarity. The color stability and conversion accuracy also need to be optimized. Utility Model Content

[0003] The problem to be solved by the present invention is to provide a personalized exterior decoration part that can realize parameterized pattern change, so as to solve the problem that the pattern of the existing personalized exterior decoration part cannot be changed.

[0004] In order to solve the above problems, the technical solution of the present invention is: the personalized exterior trim that can realize parametric pattern changes includes, from the inside to the outside, a light source layer, a black body light-shielding coating, and a translucent varnish layer, the black body light-shielding coating is engraved with the pattern to be displayed, a translucent material support layer is provided between the light source layer and the black body light-shielding coating, the black body light-shielding coating is a microporous layer with a pore size between 0.05mm-0.2mm, and a color difference control layer is provided between the black body light-shielding coating and the translucent varnish layer; the black body light-shielding coating includes a non-translucent black light-shielding paint layer and a color layer, 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 each two origins or square points is 0.2mm-0.9mm.

[0005] In the above technical solution, a more specific solution may be: the light-transmitting material support layer is a PP material with a light-shielding primer coated on its surface.

[0006] Furthermore: the color difference control layer is a light-transmitting color-shielding layer.

[0007] Furthermore: the thickness of the color difference control layer is 10um-20um.

[0008] Furthermore: the light source layer is an LED light source layer.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] The personalized exterior trim that can achieve parametric pattern changes carves out a tiny origin square dot matrix pattern on the black body light-shielding coating. Different patterns can be achieved by using different parameter settings, thus realizing personalized pattern exterior trim. By setting a microporous layer, the light transmittance is increased by about 30%, improving the light source utilization rate and reducing the total power cost of the light source electronic module by 30%, while meeting the overall visual requirements of the body color integrity. The original translucent primer layer and translucent topcoat layer are replaced by a translucent color-shielding layer, which not only simplifies the coating structure, but also makes the pattern more visible and has clear boundaries. The microporous layer is colored to weaken the color difference of the micropores, so as to achieve the effect of consistency with the body color and weaken the sense of touch step difference. On the basis of the existing hidden luminous technology, the visual integration and the appearance requirements of the same color effect as the body are enhanced. The use of a translucent varnish layer provides weather protection for the exterior trim, making the exterior trim weather-resistant in various complex climates and meeting vehicle regulations. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a front view of an embodiment of the utility model;

[0012] Markings in the figure: light source layer 1, translucent material support layer 2, black body light-shielding coating 3, color difference control layer 4, translucent varnish layer 5. DETAILED DESCRIPTION

[0013] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0014] like Figure 1The light-personalized exterior trim shown in the figure, which can realize parametric pattern changes, includes, from the inside to the 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 a different color from the body), the black body light-shielding coating 3 is a microporous layer with a pore size between 0.05mm-0.2mm, and the black body light-shielding coating 3 is engraved with the pattern to be displayed. 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 each 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's light-shielding coating, different patterns can be achieved using different parameter settings, thus realizing personalized exterior decoration; the black car body's light-shielding coating is carved into 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%, while meeting the visual requirements of the overall car body color integrity requirements.

[0015] The light-transmitting material support layer 2 is a PP material with a light-shielding primer on its surface. The light-shielding primer here is a light-shielding gray-black primer. The color difference control layer 4 is a light-transmitting light-shielding layer in the same color as the vehicle body. The thickness of the color difference control layer is 10um-20um. The light source layer 1 is an LED light source layer.

[0016] Processing methods include:

[0017] A translucent material is produced using a mold, and a light-shielding gray-black primer is sprayed on the surface of the transparent translucent material to form a translucent material support layer 2. A layer of non-translucent black light-shielding paint and a color layer are successively sprayed on the side of the translucent material support layer 2 sprayed with the light-shielding gray-black primer to form a black body light-shielding coating 3. Then, an engraving robot is used to engrave origins or square points of 0.2mm-0.3mm and a spacing of 0.2mm-0.9mm on the non-translucent 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 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 translucent 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 visual integrated color effect and reduces light blocking, provides light transmittance, and can well cover the microporous frame, weakening the microporous color difference, achieving the effect of consistency with the body color, and at the same time weakening the sense of touch step difference; after the coating line is baked, a layer of transparent varnish (that is, translucent varnish layer 5) is finally sprayed to perform weather protection treatment on the product to achieve various weather resistance conditions of the product and meet vehicle regulations. A light-emitting unit (light source layer 1), i.e., a luminous LED lamp, is installed in front of the pattern on the black 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, the 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 and the light-transmitting varnish layer 5), ultimately forming a pattern on the surface of the material, achieving the effect and function of luminous appearance.

[0018] This method realizes light-transmitting exterior trim, which not only retains the performance of automobile exterior trim but also realizes the appearance characteristics of personalized pattern changes to meet the needs of different customers.
