[0027] like Figure 1 As shown, in one embodiment, the first aspect of the utility model provides a light-transmitting decorative structure, including a grille layer 1, a transparent base layer 2 and a magic color layer 3, the transparent base layer 2 is located between the grille layer 1 and the magic color layer 3, and a diffraction grille texture is formed on the grille layer 1.
[0028] Specifically, a grid layer 1 and a color-shifting layer 3 are formed on either side of a transparent base layer 2. A diffraction grid texture is formed on the grid layer 1. This diffraction grid texture superimposes the refracted light from the underlying color-shifting layer 3, creating a light-and-dark effect. The underlying color-shifting layer 3 imparts different light colors to the translucent decorative structure, and the color of the light changes depending on the angle. This enhances the product's appearance, optimizes the user experience, and improves product competitiveness.
[0029] like Figure 2 As shown, in one embodiment, the diffraction grating texture is located on the side of the grating layer facing away from the transparent base layer.
[0030] A diffraction grating texture is formed on the side of the grating layer 1 facing away from the transparent base layer 2. The diffraction grating texture can reflect the refracted light of the magic color layer 3, giving the light-transmitting decorative structure different light colors and improving the appearance of the product.
[0031] like Figure 1 As shown, in one embodiment, the grid layer is a light-transmitting structure.
[0032] The grid layer is a light-transmitting structure, so that the refracted light of the underlying magic color layer 3 can be superimposed to form a light and dark effect.
[0033] like Figure 2 As shown, in one embodiment, the diffraction grating texture includes a plurality of mutually spaced and parallel gratings 11, and the grating 11 is a strip structure protruding from the surface of the grating layer 1 or a strip groove structure recessed in the surface of the grating layer 1; the distance between two adjacent gratings 11 is H1, and the value range of H1 is 190μm-210μm.
[0034] The diffraction grating texture comprises multiple parallel, spaced gratings 11. Through their diffraction structure, the gratings 11 superimpose the refracted light from the underlying iridescent layer 3, creating a light-and-dark effect. The underlying iridescent layer 3 imparts different light colors to the translucent decorative structure, and the color changes with angle. This enhances the product's appearance, optimizes the user experience, and increases product competitiveness.
[0035] Specifically, the value range of H1 is any point value of 190μm, 191μm, 192μm, 193μm, 194μm, 195μm, 196μm, 197μm, 198μm, 199μm, 200μm, 201μm, 202μm, 203μm, 204μm, 205μm, 206μm, 207μm, 208μm, 209μm or 210μm, or a range value consisting of any two point values; in a preferred embodiment, the value range of H1 is 195μm-205μm.
[0036] When the value range of H1 is 190μm-210μm, the grating 11 superimposes the refracted light of the underlying iridescent layer 3 through the diffraction structure of the grating 11 to form a light and dark effect; through the underlying iridescent layer 3, the translucent decorative structure is given different light colors, and the color of the light will change differently with the angle.
[0037] When the value range of H1 is less than 190μm, the grating 11 superimposes the refracted light of the lower colorful layer 3 through the diffraction structure of the grating 11, and the superimposed colors are relatively messy; when the value range of H1 is greater than 210μm, the grating 11 superimposes the refracted light of the lower colorful layer 3 through the diffraction structure of the grating 11, and the superimposed colors are relatively monotonous.
[0038] like Figure 2 As shown, in one embodiment, the grating 11 is a strip structure protruding from the surface of the grid layer 1. A single grating 11 in the grid layer 1 includes a peak end and two valley ends. The two valley ends are located on the same plane. The distance between the peak end and the valley end is H2, and the value range of H2 is 140μm-160μm. The distance between the two valley ends is H3, and the value range of H3 is 190μm-210μm.
[0039] Specifically, the value range of H2 is any point value among 140μm, 141μm, 142μm, 143μm, 144μm, 145μm, 146μm, 147μm, 148μm, 149μm, 150μm, 151μm, 152μm, 153μm, 154μm, 155μm, 156μm, 157μm, 158μm, 159μm or 160μm, or a range value consisting of any two point values; in a preferred embodiment, the value range of H2 is 145μm-155μm.
[0040] When the value range of H2 is 140μm-160μm, the grating 11 superimposes the refracted light of the underlying iridescent layer 3 through the diffraction structure of the grating 11 to form a light and dark effect; through the underlying iridescent layer 3, the translucent decorative structure is given different light colors, and the color of the light will change differently with the angle.
[0041] When the value range of H2 is less than 140 μm, the refraction angle of the grating 11 is limited, resulting in a relatively monotonous color of the translucent decorative structure; when the value range of H2 is greater than 160 μm, the refraction angle of the grating 11 is too much, and too many colors are superimposed, resulting in a relatively messy superimposed color, affecting the beauty and viewing experience.
[0042] Specifically, the value range of H3 is any point value of 190μm, 191μm, 192μm, 193μm, 194μm, 195μm, 196μm, 197μm, 198μm, 199μm, 200μm, 201μm, 202μm, 203μm, 204μm, 205μm, 206μm, 207μm, 208μm, 209μm or 210μm, or a range value consisting of any two point values; in a preferred embodiment, the value range of H3 is 195μm-205μm.
[0043] When the value range of H3 is 190μm-210μm, the grating 11 superimposes the refracted light of the underlying iridescent layer 3 through the diffraction structure of the grating 11 to form a light and dark effect; through the underlying iridescent layer 3, the translucent decorative structure is given different light colors, and the color of the light will change differently with the angle.
[0044] When the value range of H3 is less than 190μm, the grating 11 superimposes the refracted light of the lower colorful layer 3 through the diffraction structure of the grating 11, and the superimposed colors are relatively messy; when the value range of H3 is greater than 210μm, the grating 11 superimposes the refracted light of the lower colorful layer 3 through the diffraction structure of the grating 11, and the superimposed colors are relatively monotonous.
[0045] like Figure 1 As shown, in one embodiment, the grid layer 1 is made of a polyurethane layer.
[0046] Polyurethane has high gloss and high transparency, and the surface hardness can be adjusted, thereby improving the performance of translucent decorative structures in terms of gloss and transparency.
[0047] like Figure 1 As shown, in one embodiment, the thickness of the grid layer 1 is 0.5-0.9 mm.
[0048] Specifically, the thickness of the grid layer 1 is any value among 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm or 0.9 mm, or a range consisting of any two values. In a preferred embodiment, the thickness of the grid layer 1 is 0.7 μm.
[0049] When the thickness of the grid layer 1 is 0.5-0.9 mm, the grid layer 1 has good light transmittance.
[0050] like Figure 1 As shown, in one embodiment, the thickness of the magic color layer 3 is 0.15-0.25 mm.
[0051] Specifically, the thickness of the colorful layer 3 is any point value among 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.2mm, 0.21mm, 0.22mm, 0.23mm, 0.24mm or 0.25mm, or a range value consisting of any two point values; in a preferred embodiment, the thickness of the colorful layer 3 is 0.2mm.
[0052] When the thickness of the iridescent layer 3 is 0.15-0.25 mm, the iridescent layer 3 can refract its own color to the grille layer 1, forming an iridescent effect on the surface of the grille layer 1; thereby improving the product appearance, optimizing the user experience, and enhancing the competitiveness of the product.
[0053] In one embodiment, an organic mother-of-pearl texture pattern (not shown) is formed on one side of the transparent base layer 2 close to the magic color layer 3 , and the organic mother-of-pearl texture pattern is connected to the magic color layer 3 by thermal adsorption.
[0054] Specifically, an organic mother-of-pearl pattern is formed on the side of the transparent base layer 2 near the iridescent layer 3. This organic mother-of-pearl pattern and the grating 11 of the grille layer 1 form a double-layer texture. The diffraction of the grating 11 on the surface of the grille layer 1 and the reflection of the underlying texture create a new visual effect. The organic mother-of-pearl pattern is thermally adsorbed on the surface of the iridescent layer 3. Through refraction and reflection of light, a light-and-dark effect of soft mother-of-pearl light is created on the surface of the grille layer 1. Through the underlying iridescent layer 3, the soft mother-of-pearl light is imbued with different colors, and the color changes depending on the angle. This enhances the product's appearance, optimizes the user experience, and increases product competitiveness.
[0055] In one embodiment, the transparent base layer 2 is made of transparent plastic, which is selected from any one of PMMA, PC, and PP.
[0056] Specifically, the preparation process of the present application is: first, any one of PMMA, PC or PP is injection molded to form a transparent base layer 2, and an organic mother-of-pearl texture pattern is formed on one side of the transparent base layer 2, and then the grid layer 1 is injection molded on the other side of the transparent base layer 2.
[0057] The transparent base layer 2 is made of transparent plastic to facilitate the refraction and reflection of light by the transparent base layer 2 and the magic color layer 3 .
[0058] like Figure 1-Figure 2 As shown, in one embodiment, the thickness of the transparent base layer 2 is 2-4 mm.
[0059] Specifically, the thickness of the transparent base layer 2 is any point value among 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm or 4mm, or a range value consisting of any two point values; in a preferred embodiment, the thickness of the transparent base layer 2 is 3mm.
[0060] When the thickness of the transparent base layer 2 is 2-4 mm, the transparent base layer 2 can reflect the colors of the iridescent layer 3 onto the grille layer 1, creating a mother-of-pearl-like light and shade effect on the surface of the grille layer 1. It also prevents the light-transmitting decorative structure from being too thick, which would make it appear bulky and affect the aesthetics. This improves the product's appearance, optimizes the user experience, and enhances product competitiveness.
[0061] A second aspect of the present invention provides a decorative piece, comprising the above-mentioned light-transmitting decorative structure.
[0062] The decorative piece provided by the present invention uses the above-mentioned light-transmitting decorative structure to increase the overall colorful effect of the decorative piece, improve the product appearance, optimize the user experience, and enhance the competitiveness of the product.
[0063] A third aspect of the present invention provides an automobile, comprising the above-mentioned decorative component.
[0064] Similarly, the automobile provided by the present invention uses the above-mentioned decorative parts, which can enhance the overall appearance of the automobile, optimize the user experience, and enhance the competitiveness of the product.
[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
