[0024] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise specified, “plurality” means more than two; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, etc., indicating directions or positional relationships, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] In this embodiment, the circumferential edge lines of the outer surface 12 include two groups of edge lines, and each group of edge lines is arranged opposite to each other; the first direction is the extension direction of one edge line of the outer surface 12; the second direction is the extension direction of another edge line intersecting with one edge line of the outer surface 12.

[0028] like Figure 1-6 As shown, an embodiment of a metallic texture translucent automobile interior decoration part includes a decoration part body 1 made of a translucent material, the decoration part body 1 has an inner surface 11 and an outer surface 12 along the thickness direction, the inner surface 11 is sequentially provided with a primer layer 2, a metal layer 3 and a protective layer 4, and the outer surface 12 has a reflective area 13 with a concave-convex structure.

[0029] The provision of the metal layer 3 makes the surface of the interior decoration part have a metallic luster, improves the texture and reduces the plastic feeling; it has decorative effect even in dim light conditions.

[0030] The setting of the reflective area 13 with a concave-convex structure makes the light more divergent and has a three-dimensional and layered sense. When there is a light source, the light source passes through the reflective area 13 with a large divergence range and a good three-dimensional visual effect; when there is no light source, the reflective area 13 with a concave-convex structure cooperates with the metal layer 3 to enhance the three-dimensional and layered sense of the metallic luster of the metal layer 3 through the reflective area 13, thereby enhancing the visual effect of the interior decoration.

[0031] In this embodiment, the inner surface 11 is sequentially provided with a primer layer 2, a metal layer 3 and a protective layer 4, including the inner surface 11 being fully provided with the primer layer 2, the metal layer 3 and the protective layer 4, or the inner surface 11 being sequentially provided with a fully provided primer layer 2, a partially provided metal layer 3 and a fully provided protective layer 4.

[0032] like Figure 1 , Figure 4 and Figure 6 As shown, in another preferred embodiment, the reflective area 13 includes at least two reflective protrusion units 131, and the reflective protrusion unit 131 is composed of at least four reflective planes; the outer surface 12 extends along the intersecting first direction and second direction, and the reflective plane faces the first direction or the second direction.

[0033] In this embodiment, the reflective surface 1311 of the reflective protrusion unit 131 is arranged circumferentially to achieve 360-degree reflection; at the same time, the reflective effects of each reflective surface 1311 are different at different observation positions, and the differentiated reflective effects are beneficial to further enhance the three-dimensional sense of the interior decoration.

[0034] like Figure 1 and Figure 6 As shown, in another preferred embodiment, the protruding top 1312 of the reflective protruding unit 131 is in a dot shape or a line shape.

[0035] The reflective protrusion unit 131 is surrounded by a plurality of reflective planes inclined relative to a horizontal plane; the reflective protrusion unit 131 takes the outer surface 12 of the ornament body 1 as a base, and extends in a direction away from the outer surface 12 to converge into a point or a line.

[0036] Optionally, the tops of the reflective protrusion units 131 in the same interior component are all dot-shaped, or all linear-shaped, or the dot-shaped tops and the linear-shaped tops are alternately arranged according to a predetermined arrangement direction of the reflective protrusion units 131 .

[0037] When the protruding tops 1312 are arranged alternately in dot and line shapes, the reflective surface 1311 facing the same direction presents a differentiated visual effect of alternating triangles and trapezoids.

[0038] Furthermore, the intersection edges of the reflective surfaces 1311 are arranged in different directions, so that the reflective surfaces 1311 of adjacent reflective protrusion units 131 have different shapes.

[0039] In another preferred embodiment, the metal layer 3 is a logo pattern protruding from the primer layer 2 , and the protective layer 4 is coated on the metal layer 3 or the primer layer 2 .

[0040] Unique logo patterns are designed for different brands of cars. The metal layer 3 is vacuum sputtered and chrome-plated according to the logo pattern to form a metal layer 3 protruding from the primer layer 2. The metallic luster effect of the metal layer 3 is combined with the logo pattern to give the car a logo decoration effect.

[0041] In this embodiment, the inner surface 11 of the decorative part body 1 includes a primer layer 2 that is fully disposed, a metal layer 3 that is partially disposed, and a protective layer 4 that is fully disposed in sequence.

[0042] like Figure 3-4 As shown, in another preferred embodiment, the primer layer 2 is a UV paint layer with a thickness of 28-35 μm.

[0043] By providing the primer layer 2, the adhesion of the metal layer 3 is increased, thereby solving the problem that the metal layer 3 cannot be directly and effectively attached to the plastic part.

[0044] In this embodiment, the UV paint is an ultraviolet light curing paint. When the thickness of the primer layer 2 is greater than 35 μm, the thickness is too thick, resulting in poor light transmittance of the interior decoration; when the thickness of the primer layer 2 is less than 28 μm, the thickness is too thin, resulting in low adhesion between the primer layer 2 and the metal layer 3 or between the primer layer 2 and the inner surface 11 of the decorative part body 1, and poor adhesion effect.

[0045] like Figure 3-4 As shown, in another preferred embodiment, the metal layer 3 is a chromium layer with a thickness of 2-3 μm.

[0046] The metal layer 3 provides a metallic texture effect for the interior trim.

[0047] In this embodiment, vacuum sputtering chrome plating is used to form a metallic glossy texture; when the thickness of the metal layer 3 is set to >3μm, the thickness is too thick, resulting in poor light transmittance, and the metal effect is too strong, affecting the visual perception; when the thickness is set to <2μm, the thickness is too thin, reducing the adhesion of the metal layer 3, and the metallic gloss effect is too weak and not obvious, resulting in poor decorativeness.

[0048] like Figure 3-4 As shown, in another preferred embodiment, the protective layer 4 is a varnish layer with a thickness of 10-15 μm.

[0049] The protection layer 4 prevents the metal layer 3 with a metallic luster visual effect from being scratched and damaged and falling off, and blocks ultraviolet rays to prevent the metal layer 3 from being oxidized, corroded and discolored.

[0050] In this embodiment, varnish is used for spraying to form the protective layer 4; when the thickness of the protective layer 4 is greater than 15 μm, the thickness is too thick and affects the light transmittance of the interior decoration parts, resulting in poor light transmittance; when the thickness of the protective layer 4 is less than 10 μm, the thickness is too thin and leads to poor adhesion with the metal layer 3 and the decorative part body 1, making it difficult to form.

[0051] like Figure 2 , Figure 5 As shown, in another preferred embodiment, the ornament body 1 includes a light emitting receiving groove 14 , and a light source is disposed in the light emitting receiving groove 14 .

[0052] A light source is provided to realize the lighting function of the interior decoration; a light receiving groove 14 is provided to provide a space for accommodating the light source. During the day, the metal layer 3 serves as a decoration for the car; at night, the light emitted by the light source is emitted through the metal layer 3 to display the metal layer 3, and the metal layer 3 serves as a decoration for the car.

[0053] like Figure 2 , Figure 5 As shown, in another preferred embodiment, a connector 15 is connected to the circumferential edge of the slot of the light-emitting receiving slot 14. The connector 15 includes a protrusion 151. The protrusion 151 is configured to be connected to the vehicle body in a concave-convex manner.

[0054] The interior decoration part is fixed to the automobile body by the setting of the connecting piece 15. The concave-convex matching clamping structure is convenient for disassembly and installation.

[0055] Optionally, the connection member 15 is arranged in a direction extending along the thickness direction of the decoration body 1 , or in a direction perpendicular to the thickness direction of the decoration body 1 .

[0056] like Figure 2 As shown, in another preferred embodiment, the connecting member 15 includes a vehicle body abutting portion 152, and the vehicle body abutting portion 152 is configured as a spherical surface.

[0057] In this embodiment, the vehicle body abutment portion 152 is disposed on the side where the interior trimmings abut against the vehicle body base. The vehicle body abutment portion 152 is disposed to achieve multi-point contact between the vehicle body base and the interior trimmings; unlike the seamless and tight fit between the vehicle body base and the interior trimmings in surface contact, multi-point contact reduces the contact area, and forms an assembly gap between the vehicle body base and the interior trimmings, facilitating the assembly of the interior trimmings.

[0058] At the same time, the setting of the spherical structure can prevent damage and scratches on the contact surface between the interior decoration parts and the car body.

[0059] The production process steps of the automotive interior trim of this embodiment are as follows:

[0060] A decorative part body 1 is injection molded to have a reflective area 13;

[0061] Place the trim body 1 into a masking tool, leaving only the area to be sprayed, and place them into the spraying equipment for UV paint coating;

[0062] Place the trim body 1 coated with the primer layer 2 in a PVD device for vacuum sputtering. If the metal layer 3 needs to be coated with a signature pattern, cover the area other than the signature pattern on the surface of the primer layer 2 and place it in the PVD device;

[0063] The decorative part body 1 coated with the primer layer 2 and the metal layer 3 is put into the spraying equipment again for clear coating;

[0064] After drying and shaping, a metallic and light-transmitting automobile interior decoration part is obtained.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
