[0056] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0057] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it is not necessary to discuss it further in subsequent drawings.

[0058] The following is a detailed description of the technical content, structural features, achieved objectives, and effects of the present invention. The following is described in detail in conjunction with the implementation manners and the accompanying drawings.

[0059] Refer to Figure 1 , according to the first embodiment of the present application, the trim structure 100 includes a reinforcement layer 2 and a texture layer 4, and the reinforcement layer 2 and the texture layer 4 are connected. The reinforcement layer 2 can be formed by paper molding or by processing an injection-molded material. The texture layer 4 can be formed by bamboo and wood molding or by processing an injection-molded material. The trim structure 100 in the prior art does not include the reinforcement layer 2 and only has the texture layer 4. The single texture layer 4 is prone to deformation. Most of the texture layers 4 in the prior art are made of bamboo and wood materials. After laying several pre-treated long bamboo strips flat or side by side, wet wood glue combination and hot pressing processes are used to form a bamboo veneer. After the bamboo veneer is soaked in water, a tool is used to plane along the bamboo fiber direction of the bamboo veneer to obtain a sliced bamboo skin sheet of the required thickness, and the sheet is prone to deformation. In the present invention, since the reinforcement layer 2 and the texture layer 4 are connected, the strength of the reinforcement layer 2 is used to improve the deformation of the texture layer 4, which can effectively prevent its deformation and reduce its deformation amount.

[0060] In some possible embodiments, the trim structure 100 further includes an adhesive layer 3, and the adhesive layer 3 connects the reinforcement layer 2 and the texture layer 4. The adhesive layer 3 can be glue, or a combination of non-woven fabric and glue, or other substances with adhesiveness. The adhesive layer 3 is between the reinforcement layer 2 and the texture layer 4, that is, the adhesive layer 3 connects the reinforcement layer 2 and the texture layer 4, so that the reinforcement layer 2 and the texture layer 4 are tightly connected together. The reinforcement layer 2 can be formed by paper molding or processed by injection molding materials. The texture layer 4 can be formed by bamboo or wood molding or processed by injection molding materials. In the present invention, the reinforcement layer 2 and the texture layer 4 are connected by the adhesive layer 3, which can effectively prevent deformation and reduce the amount of deformation.

[0061] In some possible embodiments, the trim structure 100 further includes a substrate layer 1, and the substrate layer 1 is below the reinforcement layer 2 and the texture layer 4. The substrate layer 1 is generally made of injection molding material and has mounting feet thereon. The substrate layer 1 is mounted on the body structure of the vehicle to fix the trim structure 100. The substrate layer 1 being above the reinforcement layer 2 and the texture layer 4 can indicate that the hierarchical distribution of the trim mechanism is not fixed. From the inside out, it can be the substrate layer 1, the reinforcement layer 2, the adhesive layer 3, and the texture layer 4, or it can also be the substrate layer 1, the texture layer 4, the adhesive layer 3, and the reinforcement layer 2. Using the substrate layer 1 as the bottom layer can achieve the effect of stabilizing the trim structure 100.

[0062] In some possible embodiments, the substrate layer 1 is an injection molding plate. The materials of the injection molding plate can be acrylonitrile-butadiene-styrene (ABS), polyethylene (PE), polystyrene (ABS), polypropylene (PP), polycarbonate (PC), polyoxymethylene (POM), phenolic (PF), epoxy resin (EP), polyamide (PA), polymethyl methacrylate (PMMA), and modified materials of the foregoing categories, etc. The advantages of several injection molding materials are listed below: PP is a polymer formed by free radical polymerization of propylene monomers. It is a non-toxic, odorless, tasteless, high-density, side-chain-free, highly crystalline milky white linear polymer. It is the plastic material with the largest consumption for interior and exterior trim parts. Its advantages are low density and light weight; water absorption rate is less than 0.02%, and it is almost completely unaffected by moisture erosion; high impact strength, good processing fluidity, easy to mold, and good appearance quality of products; rich raw material sources and low price; good temperature resistance (but poor heat load deformation ability); good chemical resistance. The advantages of ABS are surface decoration and secondary processing properties, including painting, electroplating, welding, bonding, etc.; good dimensional stability and creep resistance. ABS is mainly used for decorative parts using processes such as painting, electroplating, water transfer printing, and IMD in interior and exterior trim parts. POM is a semi-crystalline plastic with high wear resistance, specific strength and specific rigidity close to metals, and good fatigue resistance. Using an injection molding structure also has good strength effect due to its moldable installation structure for mounting on the vehicle body.

[0063] In some possible embodiments, the thickness of the substrate layer 1 satisfies 2 mm ≤ T ≤ 5 mm. Mounting structures are distributed on the substrate layer 1, and they are mounted on the vehicle body structure. If the thickness of the substrate layer 1 is too small, its strength may be insufficient; if the thickness is too large, the flexibility of the decorative part's shape may be reduced. This range balances the structural strength and the flexibility of the shape, ensuring the mounting strength.

[0064] Referring to Figure 2 , in some possible embodiments, the reinforcing layer 2 includes a paper material layer 21, and the paper material layer 21 is configured as paper. The material of the paper material layer 21 can be polyethylene fiber paper, wood pulp paper, bamboo pulp paper, straw pulp paper, bagasse paper, reed paper, recycled paper, etc. Adding the paper-like paper material layer 21 can effectively provide support for the texture layer 4, increase its strength, and make the decorative part structure 100 not easily deformed. The paper material layer 21 can also be surface-treated using different processes such as pigment dyeing, spray painting, and tie-dyeing, so that the paper material layer 21 can present different texture and color effects.

[0065] In some possible embodiments, the reinforcing layer 2 further includes first and second injection molding layers 422. The material of the reinforcing layer 2 can also be injection molding materials. The following lists the advantages of several injection molding materials: PP is a polymer formed by free radical polymerization of propylene monomers. It is a non-toxic, odorless, tasteless, high-density, linear polymer with no side chains and high crystallinity, and it is a milky white color. It is the plastic material with the largest consumption in interior and exterior trim parts. Its advantages are low density and light weight; water absorption rate is lower than 0.02%, and it is almost completely unaffected by moisture erosion; high impact strength, good processing fluidity, easy to mold, and good appearance quality of products; rich raw material sources and low price; good temperature resistance (but poor heat load deformation ability); good chemical resistance. The advantages of ABS are its surface decoration and secondary processing properties, including spray painting, electroplating, welding, bonding, etc.; good dimensional stability and creep resistance. ABS is mainly used in decorative parts using processes such as spray painting, electroplating, water transfer printing, and IMD in interior and exterior trim parts. POM is a semi-crystalline plastic with high wear resistance, specific strength and specific rigidity close to metals, and good fatigue resistance.

[0066] In some possible embodiments, the thickness of the paper material layer 21 satisfies 0.1 mm ≤ T1 ≤ 2 mm. T1 is the thickness of the paper material layer 21. The material of the paper material layer 21 can be paper material or injection molding material, and its thickness is from 0.1 mm to 2 mm. If the thickness of the paper material layer 21 is too small, its strength may be insufficient; if the thickness is too large, the flexibility of the decorative part's shape may be reduced. That is, the thickness of the paper material layer 21 is 0.1 mm ≤ T1 ≤ 2 mm, and this range balances the structural strength and the flexibility of the shape.

[0067] In some possible embodiments, the adhesive layer 3 is configured for glue bonding. The adhesive layer 3 uses an adhesive to bond, and using the adhesive to bond the reinforcing layer 2 and the texture layer 4 can make the two fit tightly, increasing the strength of the trim structure 100.

[0068] In some possible embodiments, the adhesive layer 3 further includes non-woven fabric or self-adhesive or adhesive paper. Using non-woven fabric and glue in combination as the adhesive layer 3 can make the reinforcing layer 2 and the texture layer 4 fit tightly, increasing the strength of the trim structure 100; self-adhesive or adhesive paper can also make the reinforcing layer 2 and the texture layer 4 fit tightly, increasing the strength of the trim structure 100.

[0069] In some possible embodiments, the texture layer 4 includes a bamboo skin layer 41. The method of making the bamboo skin layer 41 is as follows: after laying a number of pretreated long bamboo strips flat or sideways, wet wood glue combination and hot pressing processes are used to form a bamboo veneer. After the bamboo veneer is soaked in water, a cutter cuts along the bamboo fiber direction of the bamboo veneer to obtain a sliced bamboo skin sheet of the required thickness. The bamboo skin layer 41 can achieve the effect of bamboo and wood texture, and the bamboo skin layer 41 can also be surface-treated using processes such as pigment dyeing and spray painting to enhance the aesthetics.

[0070] In some possible embodiments, the texture layer 4 further includes a second injection molding layer 42. The texture layer 4 can reflect the texture of the trim structure 100, and the material of the texture layer 4 can also be an injection molding material. The following lists the advantages of several injection molding materials: PP is a polymer formed by free radical polymerization of propylene monomers. It is a non-toxic, odorless, tasteless, high-density, side-chain-free, highly crystalline milky white linear polymer, and is the plastic material with the largest consumption in interior and exterior trim parts. Its advantages are low density and light weight; water absorption rate is lower than 0.02%, and it is almost completely unaffected by moisture erosion; high impact strength, good processing fluidity, easy to mold, and good appearance quality of products; rich raw material sources and low price; good heat resistance (but poor heat load deformation ability); good chemical resistance. The advantages of ABS are surface decoration and secondary processing properties, including spray painting, electroplating, welding, bonding, etc.; good dimensional stability and creep resistance. ABS is mainly used in decorative parts using processes such as spray painting, electroplating, water transfer printing, and IMD in interior and exterior trim parts. POM is a semi-crystalline plastic with high wear resistance, specific strength and specific rigidity close to metals, and good fatigue resistance.

[0071] In some possible embodiments, the bamboo skin layer 41 is configured as bamboo square or bamboo slices. Bamboo-wood square is a board made by gluing and splicing bamboo or wood slices and then pressing them. The specific process includes steps such as steaming, drying, compressing, and gluing, and finally forms delicate bamboo boards. This material has many advantages. It is environmentally friendly. Bamboo grows in a short time and has sustainable regrowth characteristics after being cut, meeting the low-carbon concept. It is tough. Bamboo is harder and denser than wood and has higher compressive and bending strength. It is beautiful. The bamboo pattern is clear, the color is natural, and the texture is elegant. It is durable. Bamboo does not accumulate dust, does not condense dew, and is easy to clean, avoiding bacterial reproduction and insect infestation. It is comfortable. Bamboo can adjust the environmental humidity and has the characteristics of being warm in winter and cool in summer. Healthy bamboo can absorb ultraviolet rays, helping to prevent eye diseases such as myopia. It has sound absorption and sound insulation effects. Bamboo can effectively reduce noise. Bamboo slices refer to thin sheet materials made by planing bamboo or wood slices. Bamboo slices are made by planing laminated bamboo square materials after softening. It also has its advantages. It is environmentally friendly and natural. The bamboo fibers are delicate and can be pressed into skin slices with uniform thickness. The texture is clear. The color is uniform and the touch is mild and comfortable. It has good light transmittance. It has good light transmittance and soft light, suitable for lamp decoration. It also has certain fragility. Since the bamboo skin is relatively fragile and easy to crack, usually a layer of non-woven fabric needs to be pasted on the back to enhance its use effect.

[0072] In some possible embodiments, the thickness of the bamboo skin layer 41 satisfies 0.5mm ≤ T2 ≤ 1mm. T2 is the thickness of the bamboo skin layer 41. If the thickness of the bamboo skin layer 41 is too small, it may lead to insufficient strength or inability to be processed. If the thickness is too large, it may lead to a decrease in the flexibility of the shape of the decorative part or inability to be stacked with other materials. That is, the thickness of the paper material layer 21 is 0.5mm ≤ T1 ≤ 1mm, and this range balances the structural strength and the flexibility of the shape.

[0073] In some possible embodiments, the width of the bamboo-wood texture on the surface of the bamboo skin layer 41 satisfies 1mm ≤ T3 ≤ 2mm. T3 is the width of the bamboo-wood texture on the surface of the paper skin layer. If the width of the bamboo-wood texture on the surface of the bamboo skin layer 41 is too small, it will cause inability to be processed into a shape. If it is too thick, it may lead to a decrease in the flexibility of the shape of the decorative part or inability to be stacked with other materials. That is, the width of the bamboo-wood texture on the surface of the bamboo skin layer 41 is 1mm ≤ T3 ≤ 2mm, and this range balances the structural strength and the flexibility of the shape.

[0074] Refer to Figure 3, in some possible embodiments, the trim structure 100 further includes a surface layer 5. The surface layer 5 is the outermost layer of the trim structure 100. The surface layer 5 can provide aesthetics. The surface layer 5 can adopt the burnishing foil process or the electroplating process, both of which can enhance the aesthetics of the trim mechanism. The process of using metal inserts can also be adopted to enhance the aesthetics of the trim mechanism. Metal inserts refer to metal parts embedded in automotive interior parts, which are usually used to enhance structural strength, improve appearance or achieve specific functions. The decorative design of the metal parts can enhance the visual effect of the interior. Figure 3 It reflects the overall visual effect of a trim structure 100, which can reflect paper, bamboo patterns, and also the effect of the special burnishing foil process on the surface layer 5.

[0075] , in some possible embodiments, the surface layer 5 includes a burnishing foil layer 51. The burnishing foil layer 51 is the outermost layer of the trim structure 100. The burnishing foil layer 51 adopts the burnishing foil process, which includes processes such as drawing, burnishing foil, gluing, pasting foil, and sweeping foil. After these processes, the surface gold foil effect can be achieved, enhancing its aesthetics.

[0076] , in some possible embodiments, the surface layer 5 further includes an electroplated layer 52. The electroplated layer 52 can also be the outermost layer of the trim structure 100. The electroplating process refers to the process of plating a layer of metal or alloy on the surface of metal or plastic using the principle of electrolysis. This process can not only prevent metal oxidation and extend service life, but also significantly enhance the aesthetics and functionality of the product.

[0077] Refer to Figure 4 , in some possible embodiments, the burnishing foil layer 51 is configured as a metal foil. Figure 4 The topmost burnishing foil layer 51 of reflects the gold foil effect. The material for making the burnishing foil layer 51 is a metal foil. The metal foil is very thin, usually with a thickness of less than 0.02 mm, which makes them more flexible and easier to operate during processing. However, due to the light and thin texture of the metal foil, directly heating it with an open flame will cause the foil to burn. Therefore, the burnishing foil process is not "burning" in the literal sense, but rather achieves color and texture changes through heat treatment or chemical reactions. Secondly, the color change characteristics of different metal foils under different temperatures and chemical reactions enable the burnishing foil process to create a rich variety of effects. For example, silver foil and copper foil will have different chemical reactions when heated with sulfur, generating various colorful colors and textures. Silver foil is prone to oxidation reactions with elements, while copper foil will react with oxygen to form cuprous oxide or copper oxide, resulting in color changes. These chemical reactions and temperature changes enable the metal foil to exhibit unique artistic effects.

[0078] In some possible embodiments, the reinforcing layer 2 and / or the texture layer 4 are opaque or partially translucent. The reinforcing layer 2 and the texture layer 4 are opaque or partially translucent, that is, opaque means that the light transmittance is 0, and partially translucent means that the light transmittance is not 0, that is, part of the light can be seen. When the reinforcing layer 2 and the texture layer 4 are opaque, only the texture effect can be seen, that is, the paper of the reinforcing layer 2, the bamboo skin of the texture layer 4, and the gold foil of the burnt foil layer 51 when there is a burnt foil layer 51; when one of the reinforcing layer 2 and the texture layer 4 is translucent or both are translucent, in addition to being able to see the paper of the reinforcing layer 2, the bamboo skin of the texture layer 4, and the gold foil of the burnt foil layer 51 when there is a burnt foil layer 51, the luminous effect of the texture can also be seen. The reason for the luminescence is that a light source can be arranged behind the decorative structure 100. When the reinforcing layer 2 and the texture layer 4 are translucent, the light of the texture can be seen, which improves its aesthetics.

[0079] In some possible embodiments, any one or more of the reinforcement layer 2, the texture layer 4 and the surface layer 5 may be made by laser engraving.

[0080] See also Figure 5 According to a second embodiment of the present application, a decorative part processing method is provided, comprising any one or more of the following steps:

[0081] The bamboo strips are bonded by wet glue and / or hot pressing to form a single bamboo board, and the single bamboo board is sliced after being soaked in water to obtain a bamboo skin layer 41;

[0082] The bamboo skin layer 41 and the adhesive layer 3 are laminated by heat pressing to form a bamboo skin composite layer, and the adhesive layer 3 is a non-woven fabric or adhesive backing or adhesive paper;

[0083] The bamboo skin composite layer is laser engraved and hot-pressed with the paper material layer 21 to form a bamboo paper laminate layer;

[0084] The bamboo-paper laminating layer and the injection-molded substrate layer 1 are vacuum-formed to form a bamboo-paper composite part;

[0085] The bamboo-paper composite is laminated with a burnt foil layer 51, which is a burnt foil film formed by heating a metal foil sheet at a temperature of 150° C. to 250° C. A sticker with a hollow pattern is affixed to the bamboo-paper composite, and the burnt foil film is affixed to the hollow area, and the sticker is torn off to obtain gold foil at the hollow position.
