AI Technical Summary
The existing composite panel mobile phone battery cover lacks the texture of glass, and when formed under high temperature and high pressure, the texture structure is easily destroyed, resulting in the visual effect that does not match the design effect, and the light transmittance is worse than that of glass.
One side of the glass plate is equipped with a fiberglass plate and an inner diaphragm between the glass plate and the fiberglass plate. The inner diaphragm has texture and/or color and is bonded through an OCA glue layer. A cooling medium can be injected into the inner diaphragm to improve the heat dissipation effect.
The back cover of the mobile phone not only has the texture of glass, but also improves the anti-fall performance, and can achieve diversification of colors and textures, improving the visual effect and actual performance of the product.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of mobile phone back covers, and in particular to a composite glass-textured mobile phone battery cover. Background Art
[0002] Mobile phone battery covers made of glass materials have a high appearance and texture, and currently still occupy the mainstream of the market, but glass materials are easy to break and have poor drop resistance. Therefore, in recent years, composite panels have become a research hotspot for 3D mobile phone cover materials in the post-4G era. Since composite panels have incomparable advantages over 3D glass covers in terms of cost (materials + processing), product yield and technology, they are gradually favored by various mobile phone terminals.
[0003] At present, composite sheet mobile phone battery covers do not have the texture of glass, and compared with glass, the biggest problem of composite sheet is that after the texture design, the composite sheet needs to be 3D formed under high temperature and high pressure, so the originally designed texture structure will be stretched during the high-pressure forming process, so the texture structure is damaged to a certain extent, so the visual effect of the actual product is different from the design effect. If the texture is directly transferred to the composite sheet, the light transmittance of the composite sheet is slightly worse than that of glass, so the texture effect is also weaker than that of glass. Summary of the invention
[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a composite glass-textured mobile phone battery cover.

[0010] Preferably, a heat sink and / or an integrated circuit is embedded inside the glass fiber board.
[0011] Preferably, the heat dissipation element comprises an outer film embedded in the glass fiber board, and a cooling medium encapsulated in the outer film.

[0015] In the present invention, a fiberglass board and a membrane between the glass board and the fiberglass board are arranged on one side of the glass board, and the membrane has texture and / or color.

BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 This is a schematic structural diagram of a composite glass-textured mobile phone battery cover proposed by the present invention. DETAILED DESCRIPTION
[0017] Reference Figure 1 The present invention proposes a composite glass texture mobile phone battery cover, comprising: a glass plate 1, a glass fiber plate 2 and an inner film sheet 3 between the glass plate 1 and the glass fiber plate 2, the inner film sheet 3 having texture and / or color. This design has the texture of glass, solves the problem of glass being easy to break and having poor anti-fall performance, and can also achieve the diversification of colors and textures.
[0018] Specifically, the glass fiber board 2 and the inner film sheet 3 in this embodiment are bonded by the OCA adhesive layer 4, and the specific processing method is as follows:
[0019] The OCA is pre-laminated on the glass fiber board 2 , the glass fiber board 2 with the OCA laminated thereon is laminated with the film, and then the glass fiber board 2 with the film laminated thereon is cut to a suitable size and laminated with the glass plate 1 .
[0020] In this embodiment, the thickness of the OCA adhesive layer 4 is 0.025±0.003 um.
[0021] In addition, a cooling medium is injected into the inner membrane 3 in this embodiment, and the cooling medium is paraffin. When the temperature does not exceed a specific temperature, the paraffin encapsulated in the inner membrane 3 is in a solidified state. When a certain temperature is reached, the paraffin encapsulated inside the inner membrane 3 melts and takes away the heat, thereby achieving the effect of cooling the mobile phone.
[0022] In this embodiment, a heat sink 5 and / or an integrated circuit is embedded inside the glass fiber board 2, so as to better realize the integrated functions of heat dissipation, antenna, wireless charging, etc.
[0023] Furthermore, the heat sink 5 includes an outer film embedded in the glass fiber board 2 and a cooling medium encapsulated in the outer film. Heat is transferred to the cooling medium inside the outer film through the outer film for cooling.
[0024] Furthermore, the cooling medium in the outer film is paraffin. When the temperature does not exceed a certain value, the paraffin encapsulated in the outer film is in a solidified state. When a certain temperature is reached, the paraffin encapsulated inside the outer film melts and takes away the heat, thereby achieving a cooling effect.
[0025] Furthermore, at least one side of the glass fiber board 2 is provided with an embedding groove, and the heat sink 5 is embedded in the embedding groove, and its outer film is coplanar with the board surface of the glass fiber board 2, so that the outer film in the heat sink 5 can serve as a protective film to protect the board surface of the glass fiber board 2.
[0026] In addition, if the fiberglass board 2 is too thin, the strength is insufficient, and if it is too thin, the internal space is limited, and there is no space for embedding related components such as heat dissipation, antennas, and wireless charging. If it is too thick, the thickness of the mobile phone will increase. Therefore, in this embodiment, the thickness of the fiberglass board 2 is 0.2mm-0.4mm.
[0027] As can be seen from the above, the present invention arranges a glass fiber board 2 and a membrane between the glass board 1 and the glass fiber board 2 on one side of the glass board 1, and makes the membrane have texture and / or color. The mobile phone back cover of this design has the texture of glass, solves the problem of easy breakage of glass and poor anti-fall performance, and can also achieve diversification of colors and textures.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
