[0027] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Please refer to Figures 1 - 6 , a moisture-proof, heat-dissipating and light-shielding sheet, including a substrate 1, a coating structure 2 is arranged on the top of the substrate 1, and a protective film 3 is arranged on the top of the coating structure 2;

[0029] A connection ring 5 is arranged on the outer side of the substrate 1, and heat conduction points 6 are arranged at both the upper and lower ends of the connection ring 5; a sleeve body 7 is arranged on the outside of the connection ring 5, and a heat dissipation sleeve 8 is arranged on the outside of the sleeve body 7;

[0030] A first chamber 81 and a second chamber 82 are opened on the outer side wall of the heat dissipation sleeve 8, a first support plate 9 is arranged inside the first chamber 81, a second support plate 10 is arranged inside the second chamber 82, and a fitting groove 83 for fitting the sleeve body 7 is opened on the inner side wall of the heat dissipation sleeve 8;

[0031] The projections of the first support plate 9 and the second support plate 10 on the same horizontal plane are in an "X" shape;

[0032] The coating structure 2 that is set up can be used for normal use of the shading sheet, and the coating structure 2 has a moisture-proof effect. The first moisture-proof layer 221 and the second moisture-proof layer 223 that are set in the coating structure 2 are used to effectively prevent moisture from the entire shading sheet, thereby reducing the probability of the shading sheet getting wet. At the same time, the heat dissipation sleeve 8 that is set up can be made of aluminum as a whole, which is wrapped around the entire substrate 1 and the outside of the coating structure 2 to play an external supporting and protective effect. At the same time, the first chamber 81 and the second chamber 82 opened on the heat dissipation sleeve 8 are respectively provided with a first support plate 9 and a second support plate 10, and the two are in an "X" shape, which can not only effectively dissipate heat, but also play an overall supporting effect, which is beneficial to the overall use of the shading sheet and has a better use effect.

[0033] Specifically, the coating structure 2 includes a black coating 21 coated on the upper and lower end surfaces of the substrate 1, and a moisture-proof functional layer 22 is provided on the black coating 21 at the upper end of the substrate 1; an optical film layer 4 is bonded to the bottom of the black coating 21 at the lower end of the substrate 1 by an adhesive; the moisture-proof functional layer 22 includes a first moisture-proof layer 221 bonded to a release film 222 by an adhesive, and a second moisture-proof layer 223 bonded to a protective film 3 by an adhesive, and the release film 222 is bonded between the first moisture-proof layer 221 and the second moisture-proof layer 223 by an adhesive;

[0034] By setting the optical film layer 4 near the light-emitting part of the electronic product, it can reduce the reflection of the optical surface and prevent the excess light from being emitted and affecting people's use; by setting the first moisture-proof layer 221 and the second moisture-proof layer 223, it can effectively achieve the moisture-proof effect, and the moisture-proof layer can be made of silicone film.

[0035] Furthermore, the hot spot 6 on the connecting ring 5 has at least three layers of annular structure, and the diameter of the hot spot 6 in every two adjacent layers of annular structure gradually decreases from the inside to the outside; the connecting ring 5 and the sleeve body 7 are both made of transparent materials, and the hot spot 6 is made of black heat-absorbing material;

[0036] pass Figure 2 and Figure 3It can be seen that the connecting ring 5 is placed outside the base material 1, and the two can be integrally formed. The black coating 21 is coated not only on the outside of the base material 1 but also on the outside of the sleeve body 7, thus avoiding the phenomenon of printing leakage or unevenness at the edge of the base material 1 and having a better use effect. At the same time, since both the connecting ring 5 and the sleeve body 7 are made of perspective materials, and the heat conduction point 6 is made of black heat-absorbing material, when coating the black coating 21, it can be effectively observed whether the coating on the sleeve body 7 is precise. And once there are scratches on the sleeve body 7, they can be easily seen, which is conducive to timely replacement or repair. Moreover, the diameter of the heat conduction point 6 gradually decreases from the inside to the outside, enabling it to absorb the heat on the base material 1 and making the heat dissipation sleeve 8 dissipate heat more effectively. The gradual decrease in the diameter of the heat conduction point 6 is on the one hand to let the heat conduction point 6 play a role in temporarily storing heat in the middle, avoiding the heat being transferred to the heat dissipation sleeve 8 all at once and making the heat dissipation sleeve 8 dissipate heat more stably, and on the other hand to reduce material loss and cost. Of course, correspondingly, if cost is not considered and in order to increase the heat dissipation effect of the heat dissipation sleeve 8, as a better solution, the heat conduction point 6 can also be set to the same size for auxiliary heat conduction.

[0037] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
