[0007] A plurality of light-transmitting units are provided and are formed at the through holes in a one-to-one correspondence; and a thickness of the light-transmitting unit is equal to a thickness of the through hole.

[0008] Optimally, the main body unit and the light-transmitting unit are integrally formed by slush molding.

[0009] Furthermore, the thickness of the main unit and the light-transmitting unit are independently 0.8-2 mm.

[0010] Furthermore, the plurality of through holes are arranged into a neat through hole array, and the shape of the through holes is circular, square, round, polygonal or star-shaped.

[0011] Optimally, the light-transmitting unit is transparent.

[0012] Furthermore, it also includes a UV coating formed on any surface of the epidermis layer, and the thickness of the UV coating is 10-150 μm.

[0013] Furthermore, it also includes a foaming layer formed on the other surface of the epidermis layer and an adhesive layer formed on the outer surface of the foaming layer; the foaming layer is made of PU and has a thickness of 1-5 mm; the adhesive layer has a thickness of 20-50 μm.

[0014] Due to the application of the above technical scheme, the utility model has the following advantages compared with the prior art: the light-transmitting polyvinyl chloride skin of the utility model at least includes a skin layer, and the skin layer has a main unit and a light-transmitting unit, so that light can directly penetrate the skin through the light-transmitting unit, greatly enhancing the interior aesthetics of the skin; and the process is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a first embodiment of the light-transmitting polyvinyl chloride skin of the utility model;

[0016] Figure 2 This is a second embodiment of the light-transmitting polyvinyl chloride skin of the utility model. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] Example 1

[0019] This embodiment provides a light-transmitting polyvinyl chloride skin, such as Figure 1 As shown, it comprises a skin layer 20 , and the skin layer 20 mainly comprises a main body unit 1 and a light-transmitting unit 2 .

[0020] Among them, the main unit 1 is provided with a plurality of through holes, the actual number and size of the through holes can be conventionally selected according to actual needs (usually selected according to the transmittance and the light transmission position), and the size is preferably in the micrometer to millimeter level (the spacing between two adjacent through holes is in the micrometer to centimeter level); the plurality of through holes are preferably arranged in a neat through hole array, and the shape of the through holes is conventional or unconventional such as circular, square, round, polygonal or star-shaped, as long as the corresponding mold can be made. The through hole runs through the main unit 1, so that the depth of the through hole is equal to the thickness of the main unit 1. The light-transmitting unit 2 is also a plurality of, and its number is consistent with the aforementioned through holes, and is formed at the through holes in a one-to-one correspondence; in terms of the convenience of the manufacturing process, the thickness of the light-transmitting unit 2 is preferably equal to the thickness of the through hole, and the thickness of the main unit 1 and the light-transmitting unit 2 are preferably 0.8~2mm independently of each other (of course, it can also be set to be greater than or less than the thickness of the through hole as needed).

[0021] In this embodiment, the main body unit 1 and the light-transmitting unit 2 are integrally formed by slush molding to simplify the molding process as much as possible. The light-transmitting unit 2 is preferably transparent to ensure the light transmittance of the light-transmitting polyvinyl chloride surface.

[0022] Example 2

[0023] This embodiment provides a light-transmitting polyvinyl chloride skin, which includes the skin layer 20 in embodiment 1, and further includes a UV coating 10, a foaming layer 30 and an adhesive layer 40, such as Figure 2 shown.

[0024] Among them, the UV coating 10 is formed on any surface of the epidermis 20 by a conventional coating process, and its color needs not to affect the light transmittance of the epidermis 20, so it is preferably transparent); when in use, the UV coating 10 is on the outside of the entire light-transmitting polyvinyl chloride epidermis (that is, the side of the light-transmitting polyvinyl chloride epidermis facing the consumer when in use). At this time, the introduction of the UV coating 10 overcomes the defects of the epidermis 20 being easy to accumulate dust, difficult to clean, and not scratch-resistant, so that the luminous polyvinyl chloride epidermis is easy to clean and scratch-resistant during use. The thickness of the UV coating 10 is preferably 10~150μm.

[0025] The foaming layer 30 is formed on the other surface of the epidermis layer 20 (i.e., the foaming layer 30 and the UV coating 10 are respectively located on both sides of the epidermis layer 20), and its material is a conventional polyurethane foaming material (i.e., PU), and its thickness is preferably 1-5 mm. The bonding layer 40 is formed on the outer surface of the foaming layer 30 (i.e., the surface away from the epidermis layer 20), and is used to bond the foaming layer 30 and the substrate to be covered (such as automobile dashboards, furniture, etc.), and can be selected from existing conventional glue or film, etc., and its thickness is preferably 20-50 μm.

[0026] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
