[0005] A metallic layer with a gold or silver luster, and a thickness of 0.05mm-0.3mm;

[0006] A wood layer, with a thickness of 0.2mm-0.8mm, covers the upper surface of the metal layer and is fixed to the metal layer by a connecting layer.

[0007] In this process, the wood layer is laser-engraved to reveal the metal layer, creating a composite structure where the wood material is inlaid with metal patterns.

[0008] Another aspect of this application discloses a method for manufacturing automotive interior trim materials, comprising:

[0009] Prepare a metal plate with a thickness of 0.05mm-0.3mm and a gold or silver luster;

[0010] Prepare a piece of wood board of the same size and with a thickness of 0.2mm-0.8mm;

[0011] The wood panels and metal panels are bonded or injection molded together to make them a single unit.

[0012] Laser engraving is performed on the surface of the wooden board to expose the color of the metal plate underneath and form the desired pattern.

[0013] The automotive interior trim material and manufacturing method provided in this application can realize a new composite material that combines the texture of wood and the luster of metal, and can form any desired metallic luster pattern, greatly enhancing the space for personalized design. Designers can realize a wider range of design concepts and meet people's various personalized needs. Attached Figure Description

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer and more understandable, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0020] In this application, terms referring to location, such as up, down, top, bottom, inside, outside, high, and low, are based on the position of the automotive interior trim material under normal use.

[0021] One aspect of this application provides an automotive interior trim material, comprising:

[0022] A metallic layer with a gold or silver luster, and a thickness of 0.05mm-0.3mm;

[0023] A wood layer, with a thickness of 0.2mm-0.8mm, covers the upper surface of the metal layer and is fixed to the metal layer by a connecting layer.

[0024] In this process, the wood layer is laser-engraved to reveal the metal layer, creating a composite structure where the wood material is inlaid with metal patterns.

[0025] In at least one embodiment, the metal layer is aluminum or copper.

[0026] In at least one embodiment, the material of the wood layer is rosewood.

[0027] In at least one embodiment, the metal pattern is a discontinuous line.

[0028] In at least one embodiment, the metal pattern is further laser-engraved until it becomes translucent.

[0029] In at least one embodiment, the bonding layer comprises an adhesive and a nonwoven fabric.

[0030] In at least one embodiment, the connecting layer is formed by injection molding.

[0031] Another aspect of this application discloses a method for manufacturing automotive interior trim materials, comprising:

[0032] Prepare a metal plate with a thickness of 0.05mm-0.3mm and a gold or silver luster;

[0033] Prepare a piece of wood board of the same size and with a thickness of 0.2mm-0.8mm;

[0034] The wood panels and metal panels are bonded or injection molded together to make them a single unit.

[0035] Laser engraving is performed on the surface of the wooden board to expose the color of the metal plate underneath and form the desired pattern.

[0036] In at least one embodiment, the step further includes:

[0037] Further laser engraving is performed on a portion of the metal in the pattern to create a translucent effect.

[0038] In at least one embodiment, the automotive interior trim material is cut and bent to form an automotive interior trim surface of the desired shape.

[0039] The specific implementation process of this application will be described in detail below with reference to the accompanying drawings.

[0040] like Figure 1The diagram shown is a cross-sectional view of an automotive interior trim material in one embodiment of this application. The lower layer is a metal layer 1, which can be any shiny metal, preferably gold or silver, such as aluminum or copper. The metal layer 1 has a planar structure with a thickness between 0.05mm and 0.3mm, for example, 0.1mm, 0.15mm, or 0.2mm. A connecting layer 3 is disposed above the metal layer 1. The connecting layer 3 can be an adhesive layer or an injection-molded layer. A wood layer 2 is disposed above the connecting layer 3, and the connecting layer 3 firmly fixes the wood layer 2 to the metal layer 1. Together, the three elements form a unified composite structure; the wood layer 2 can be made of any natural or synthetic wood board, and the wood layer 2 can be colored to enhance its woody aesthetics; the thickness of the wood layer 2 is between 0.2mm and 0.8mm; the grooves 4 formed by laser engraving on the wood layer 2 display the color of the metal layer 1; the grooves 4 can be multiple regular or irregular discontinuous grooves, or grooves forming a continuous pattern, and the pattern formed by the grooves 4 can be multiple straight lines, curves, or any geometric pattern, or an aesthetically pleasing streamlined pattern.

[0041] like Figure 2 As shown, the color of the underlying metal layer 1 is revealed after the wood layer 2 is laser-engraved in straight lines. The color of the metal layer 1 forms an overall visual effect with continuous and discontinuous lines interspersed.

[0042] like Figure 3 As shown, the wood layer 2 is made of rosewood, and the metal layer 1 is made of gold metal. Therefore, after the wood layer 2 is laser-engraved, the gold color of the metal underneath is displayed, forming a striped pattern of wood color and gold.

[0043] like Figure 4 As shown, in addition to the striped metal color displayed by laser engraving, the wooden layer 2 also has a pattern logo laser engraved. The metal layer corresponding to the pattern logo is thinner than other areas or has fine holes, so that when a light-emitting device is set below it, the light can pass through the pattern logo to create a better sense of design.

[0044] Figure 5 A flowchart illustrating a method for manufacturing an automotive interior trim material is shown, including:

[0045] Prepare a metal plate with a thickness of 0.05mm-0.3mm and a gold or silver luster;

[0046] Prepare a piece of wood board of the same size and with a thickness of 0.2mm-0.8mm;

[0047] The wood panels and metal panels are bonded or injection molded together to make them a single unit.

[0048] Laser engraving is performed on the surface of the wooden board to expose the color of the metal plate underneath and form the desired pattern.

[0049] Laser engraving patterns can be Figures 1-4 Any of the patterns shown.

[0050] It can also include the step of laser engraving a portion of the metal on the pattern to make that portion of the metal translucent.

[0051] It may further include the step of cutting and bending the automotive interior trim material to form the desired shape of the automotive interior trim surface.
