DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] Example 1: Figure 1 As shown, a light-transmitting coating structure includes:

[0039] In this embodiment, the hollow cavity 304 on the paint surface portion 300 is formed by engraving using existing laser engraving technology, and the presence of the laser isolation layer 200 can protect the structure of the light-transmitting portion 100 from being destroyed by the laser, so that the color of the light-transmitting portion 100 can be exposed through the hollow cavity 304, forming a differentiated color with different vehicle body colors. Compared with the existing embedded split manufacturing method, the light-transmitting coating structure in this application will not have any seams, and the overall shape is more beautiful; and the use of laser engraving technology allows the shape of the pattern area to be changed according to actual production needs.

[0040] Specifically, the laser isolation layer 200 includes a main body and laser-resistant plastic particles doped on the main body. The main body is composed of a transparent film or a coating layer. The laser isolation layer 200 is light-transmissive.

[0041] In the embodiment, the laser resistant plastic particles are generally selected from infrared laser resistant plastic particles or ultraviolet laser resistant plastic particles, and the transparent film can be made of PC material or a mixture of PC material and other materials. The laser isolation layer doped with laser resistant plastic particles here can isolate laser wavelengths in the range of 280-360nm, which can effectively isolate about 80% of the laser. The main body can also use a coating layer and mix the laser resistant plastic particles at the same time and then form a laser isolation layer 200 after coating.

[0042] Preferably, the paint surface portion 300 includes a primer layer 301 disposed on the laser isolation layer 200 , a color paint layer 302 is disposed on the primer layer 301 , and the hollow cavity 304 is disposed on the primer layer 301 and the color paint layer 302 .

[0043] Further preferably, a protective varnish layer 303 is provided on the color paint layer 302 , and the color paint layer 302 and the protective varnish layer 303 are sequentially provided on the primer layer 301 .

[0044] In this embodiment, the primer layer 301 can improve the adhesion ability of the color paint, and can also play an anti-corrosion and anti-rust role. The presence of the protective varnish layer 303 can protect the primer layer 301 and the color paint layer 302, thereby increasing the service life of the color paint layer 302.

[0045] Further preferably, the light-transmitting portion 100 includes a light-transmitting ink layer 101 , and the light-transmitting ink layer 101 and the paint portion 300 are respectively located on two opposite sides of the laser isolation layer 200 .

[0053] As a preferred solution, a first anti-impact protective layer 104, a PVD coating 102, a laser isolation layer 200, a primer layer 301, a color paint layer 302 and a protective varnish layer 303 are sequentially provided on the vehicle body.

[0054] Example 5, as Figure 5 As shown, the rest of the structure is the same as that of the third embodiment, with the only difference being that the first connection layer includes a first membrane substrate layer 103 .

[0058] Example 7, as Figure 7 As shown, the rest of the structure is the same as that of the first embodiment, with the only difference being that the light-transmitting portion 100 includes a light-transmitting ink layer 101 , and a second film substrate layer 105 and a second anti-impact protection layer 106 are respectively provided on two opposite sides of the light-transmitting ink layer 101 .

[0059] As a preferred solution, the vehicle body is sequentially provided with a second anti-impact protection layer 106, a light-transmitting ink layer 101, a second membrane substrate layer 105, a laser isolation layer 200, a primer layer 301, a color paint layer 302 and a protective varnish layer 303.

[0060] In this embodiment, for the formation of a large-area pattern area, the coating process of the light-transmitting ink layer 101 directly on the vehicle body is relatively time-consuming. Therefore, in this application, the light-transmitting ink layer 101 is first coated on the second membrane substrate layer 105, and then the light-transmitting ink layer 101 with the second membrane substrate layer 105 is injection molded onto the second anti-impact protective layer 106 using an injection molding process to achieve the connection between the vehicle body and the light-transmitting ink layer 101, thereby reducing the coating and molding time.

[0061] It is worth mentioning that the first membrane substrate layer 103 and the second membrane substrate layer 105 are made of the same material, both of which can be PVD materials, and the first anti-impact protection layer 104 and the second anti-impact protection layer 106 are made of the same material, both of which can be silicone grease.

[0062] Example eight, as Figure 8 As shown, the rest of the structure is the same as that of the second embodiment, with the only difference being that the light-transmitting portion 100 includes a PVD coating 102 , and a second film substrate layer 105 and a second anti-impact protection layer 106 are respectively provided on two opposite sides of the PVD coating 102 .

[0063] As a preferred solution, the vehicle body is sequentially provided with a second anti-impact protective layer 106 ; a PVD coating 102 , a second membrane substrate layer 105 , a laser isolation layer 200 , a primer layer 301 , a color paint layer 302 and a protective varnish layer 303 .

[0064] In this embodiment, for the formation of a large-area pattern area, the coating process of the PVD coating 102 directly on the vehicle body is relatively time-consuming. Therefore, in this application, the PVD coating 102 is first coated on the second diaphragm substrate layer 105, and then the PVD coating 102 with the second diaphragm substrate layer 105 is injection molded onto the second anti-impact protective layer 106 using an injection molding process to achieve the connection between the vehicle body and the PVD102 coating, thereby reducing the coating and molding time.

[0065] In all the above embodiments, the color of the light-transmitting portion 100 is preferably silver.

The biggest difference here from Example 7 is that the material of the second membrane substrate layer 105 itself contains the material of the laser isolation layer 200, so that the laser isolation layer 200 can be omitted.

[0068] Example 10, as Figure 10 As shown, the rest of the structure is the same as that of the first embodiment, with the only difference being that the light-transmitting portion 100 includes a PVD coating 102 , and a second film substrate layer 105 and a second anti-impact protection layer 106 are respectively provided on two opposite sides of the PVD coating 102 .

[0069] As a preferred solution, a second anti-impact protective layer 106, a PVD coating 102, a second membrane substrate layer 105, a primer layer 301, a color paint layer 302 and a protective varnish layer 303 are sequentially provided on the vehicle body. The biggest difference here from Example 7 is that the material of the second membrane substrate layer 105 itself contains the material of the laser isolation layer 200, so that the laser isolation layer 200 can be omitted.

[0070] A vehicle comprises the above-mentioned light-transmitting coating structure.

[0071] More preferably, the vehicle body is further included, the vehicle body includes a transparent substrate layer 400 , and the light-transmitting portion 100 is disposed on the transparent substrate layer 400 .
