Description

Technical Field

[0001] This invention relates to the technical field of automotive trim, and particularly to an automotive trim. Background Technology

[0002] More and more automotive trim pieces are integrating optical lighting designs. Large areas of interior trim surfaces, including door panels, instrument panels and dashboards, door trim strips, sunroofs, doors, and door handles, are now illuminated. When not in use, they display surface textures, and when activated, they display patterns, satisfying users' visual experience needs.

[0003] A current automotive decorative component includes a translucent substrate and light-emitting components. A decorative film is adhered to the outer surface of the translucent substrate. This decorative film has a translucent portion and a light-blocking portion. When illuminated, the shape and pattern of the translucent portion are displayed, achieving a decorative effect. However, since the decorative film is adhered to the outside of the translucent substrate, it may be scratched, affecting the aesthetics. Furthermore, because the light emitted by the light-emitting components is generally diffused, the light near the light source is sufficient, while the light further away from the light source is insufficient. To ensure uniform brightness throughout the automotive decorative component, multiple light-emitting components are used, causing partial overlap of the light emitted by multiple light-emitting components to solve the problem of uneven brightness in different areas of the automotive decorative component. However, this can cause excessively high brightness in some areas of the automotive decorative component, leading to glare. Summary of the Invention

[0004] The main objective of this invention is to provide an automotive trim piece that effectively solves the problem of excessive brightness in existing automotive trim pieces, which causes glare.

[0005] To achieve the above objectives, the technical solutions of the present invention are as follows:

[0006] This invention provides an automotive trim piece, comprising:

[0007] A light-transmitting substrate having a light-transmitting viewing portion and a receiving cavity, wherein the light-transmitting viewing portion is located above the receiving cavity;

[0008] A decorative panel is disposed within the receiving cavity;

[0009] A light-transmitting base plate is installed below the decorative panel and closes the lower side of the receiving cavity;

[0010] A light-emitting component is installed below the light-transmitting base plate. The light emitted by the light-emitting component is diffused outward through the light-transmitting base plate and the light-transmitting substrate. Under orthographic projection, the light-emitting component is located in the center of the light-transmitting base plate.

[0011] The light-transmitting base plate has multiple light-shielding layers on its surface facing the light-emitting component, and the light-shielding range of the multiple light-shielding layers gradually increases from the outside to the inside.

[0012] Compared with the prior art, the present invention provides an automotive decorative part, which is provided from top to bottom as a light-transmitting substrate, a decorative panel, a light-transmitting base plate, and a light-emitting component. Multiple light-shielding layers with gradually increasing light-shielding range from the outside to the inside are sprayed on the lower surface of the light-transmitting base plate, and the multiple light-shielding layers are located in the center of the light-emitting component. The multiple light-shielding layers simultaneously block the light emitted by the light-emitting component. The closer the light-shielding layers are to the center, the higher the degree of overlap, and the better the light blocking effect. This corresponds to the density of the light emitted by the light-emitting component, so that the luminance of the car decorative part is consistent and uniform when it is illuminated, and the light is soft and not dazzling, effectively improving the aesthetics of the car decorative part.

[0013] In a preferred embodiment, the plurality of light-shielding layers are arranged in a centrally symmetrical manner relative to the light-emitting component.

[0014] In a preferred embodiment, each light-shielding layer is made of black light-shielding paint.

[0015] In a preferred embodiment, the light-shielding layer has four layers, each with a thickness of 12 micrometers.

[0016] In a preferred embodiment, a textured film is adhered to the upper surface of the decorative panel, the textured film having a textured pattern; the light-transmitting viewing part has a three-dimensional textured structure with multiple diamond-shaped facets interspersed, the three-dimensional textured structure being processed on the upper surface of the receiving cavity.

[0017] In a preferred embodiment, the texture pattern has crisscrossing first zigzag lines; the three-dimensional texture structure has second zigzag lines; the first zigzag lines and the second zigzag lines are not on the same vertical plane.

[0018] In a preferred embodiment, the automotive trim further includes a housing with an opening at the top. The light-transmitting substrate, decorative panel, light-transmitting base plate, and light-emitting components are all installed inside the housing, and the light-transmitting viewing section is correspondingly arranged with the opening.

[0019] In a preferred embodiment, a mounting cavity is formed between the outer shell and the light-transmitting base plate, and the light-emitting component is disposed within the mounting cavity.

[0020] In a preferred embodiment, the light-emitting component is a cold light lamp.

[0037] Combination Figures 1 to 7 As shown, the present invention provides an automotive trim piece, comprising:

[0038] A light-transmitting substrate having a light-transmitting viewing portion and a receiving cavity, wherein the light-transmitting viewing portion is located above the receiving cavity;

[0039] A decorative panel is disposed within the receiving cavity;

[0040] A light-transmitting base plate is installed below the decorative panel and closes the lower side of the receiving cavity;

[0041] A light-emitting component is installed below the light-transmitting base plate. The light emitted by the light-emitting component is diffused outward through the light-transmitting base plate and the light-transmitting substrate. Under orthographic projection, the light-emitting component is located in the center of the light-transmitting base plate. The light-emitting component is a light-emitting strip.

[0042] The light-transmitting base plate has multiple light-shielding layers on its surface facing the light-emitting component, and the light-shielding range of the multiple light-shielding layers gradually increases from the outside to the inside.

[0043] Compared with the prior art, the present invention provides an automotive decorative part, which is provided from top to bottom as a light-transmitting substrate, a decorative panel, a light-transmitting base plate, and a light-emitting component. Multiple light-shielding layers with gradually increasing light-shielding range from the outside to the inside are sprayed on the lower surface of the light-transmitting base plate, and the multiple light-shielding layers are located in the center of the light-emitting component. The multiple light-shielding layers simultaneously block the light emitted by the light-emitting component. The closer the light-shielding layers are to the center, the higher the degree of overlap, and the better the light blocking effect. This corresponds to the density of the light emitted by the light-emitting component, so that the luminance of the car decorative part is consistent and uniform when it is illuminated, and the light is soft and not dazzling, effectively improving the aesthetics of the car decorative part.

[0044] In this invention, the light emitted by the light-emitting component is diffused through the wall surface of the translucent substrate to the translucent viewing area. Compared with existing automotive trim parts that expose the texture film, placing the trim panel within the receiving cavity of the translucent substrate effectively prevents scratches and helps protect the texture film on the upper surface of the trim panel; the texture structure of the translucent substrate is placed on the surface of the receiving cavity, which also helps protect the texture structure from scratches; effectively improving the service life of automotive trim parts; and reducing the number of light-emitting components required for the same display range, effectively reducing manufacturing costs, while providing relatively lower brightness that is soft and not dazzling.

[0045] In one embodiment, the plurality of light-shielding layers are arranged in a centrally symmetrical manner relative to the light-emitting component to further improve the brightness consistency of the light-transmitting viewing area and further uniformize the brightness.

[0046] In one embodiment, each light-shielding layer is made of black light-shielding paint. Black has a good light absorption effect, thus providing a good light-shielding effect, effectively reducing the number of light-shielding layers and simplifying the process steps.

[0047] In one embodiment, the light-shielding layer has four layers, each with a thickness of 12 micrometers, to ensure the light-shielding effect, thereby making the luminance consistent and the brightness uniform.

[0048] In one embodiment, a textured film is adhered to the upper surface of the decorative panel, the textured film having a textured pattern; the light-transmitting viewing section has a three-dimensional textured structure composed of multiple interlaced rhomboid diamond facets, the three-dimensional textured structure being machined on the upper surface of the receiving cavity. Due to the refraction of light by the interlaced rhomboid diamond three-dimensional structure, when the light-emitting component is not emitting light, external light is reflected by the rhomboid three-dimensional structure, and the decorative panel displays the textured structure of the light-transmitting viewing section and the background color of the textured film, without showing the textured pattern of the textured film; when the light-emitting component emits light, light is emitted from inside the automotive decorative part, and the textured pattern of the textured film passes through the light-transmitting viewing section after light refraction, the decorative panel displays both the textured pattern of the textured film and the textured structure of the light-transmitting viewing section. Compared with existing automotive illuminated interior parts that display a single textured pattern when emitting light, this invention can display not only the textured structure of the light-transmitting viewing section but also the textured pattern of the textured film, resulting in a better visual effect.

[0049] In one embodiment, the texture pattern has intersecting first zigzag lines; the three-dimensional texture structure has second zigzag lines; the first zigzag lines and the second zigzag lines are not on the same vertical plane, so as to stagger the first zigzag lines and the second zigzag lines, avoiding partial overlap of the texture pattern and the three-dimensional texture structure, effectively allowing the user to clearly see the complete texture pattern and the complete three-dimensional texture structure, thereby improving the aesthetics of the automotive trim. The vertical plane refers to a plane perpendicular to the horizontal plane, passing through the first zigzag line or the second zigzag line.

[0050] In one embodiment, the automotive trim further includes a housing with an opening at the top. The translucent substrate, decorative panel, translucent base plate, and light-emitting component are all installed inside the housing, and the translucent viewing section corresponds to the opening. The housing encapsulates the translucent substrate, decorative panel, translucent base plate, and light-emitting component, allowing the automotive trim to be assembled as a single unit for easy installation. The housing has removable sealing plates on its sides or bottom for convenient assembly and disassembly.

[0051] Furthermore, an installation cavity is formed between the outer shell and the light-transmitting base plate, and the light-emitting component is disposed in the installation cavity, which is beneficial for protecting the light-emitting component. On the other hand, since there is a gap between the outer shell and the light-transmitting base plate, it is beneficial for heat dissipation, reducing the heat conduction of the heat emitted by the light-emitting component during operation to the surface of the light-transmitting substrate, thereby reducing the surface temperature of the light-transmitting substrate and effectively preventing the user from getting hot when touching the surface of the light-transmitting substrate.

[0052] In one embodiment, the light-emitting component is a cold light lamp. Cold light lamps have low power, high illuminance, good color temperature, and generate virtually no heat when emitting light, effectively preventing users from getting burned when touching the surface of the light-transmitting substrate.

[0053] This invention is not limited to the above-described embodiments. If any modifications or variations to this invention do not depart from the spirit and scope of this invention, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this invention, then this invention also intends to include such modifications and variations.
