Some lens films even have additional functions, such as preventing ultraviolet rays from passing through and reducing glare. Mobile phone lens films are usually made of PET or glass. You can choose the style and size that suits your mobile phone.
[0003] Existing mobile phone lens films are usually composed of a glass layer and an AB glue bracket, the glass layer is bonded to the AB glue bracket, and the glass layer and the AB glue bracket are penetrated with a first through hole at the corresponding position of the mobile phone flash and noise reduction hole.

[0006] The present application provides a mobile phone lens explosion-proof film that adopts the following technical solutions:
[0007] A mobile phone lens explosion-proof film comprises a glass layer and an AB glue bracket, wherein the glass layer is provided with an explosion-proof film layer, the surface of the glass layer is bonded to one end surface of the explosion-proof film layer, and the AB glue bracket is bonded to the other end surface of the explosion-proof film layer; the AB glue bracket is used to bond to the mobile phone lens; the AB glue bracket is provided with a lens hole; the glass layer, the explosion-proof film layer and the AB glue bracket are provided with a flash hole; the glass layer, the explosion-proof film layer and the AB glue bracket are provided with a noise reduction hole.

The AB glue bracket can be used to fit the mobile phone lens so that the mobile phone lens film can be attached to the mobile phone lens. The AB glue bracket is penetrated with a lens hole, and the glass layer, the explosion-proof film layer and the AB glue bracket are penetrated with a flash hole and a noise reduction hole so that the mobile phone lens can ensure the camera function, and the lens hole is penetrated to ensure that the camera can capture images normally.
[0009] Preferably, the explosion-proof film layer includes a transparent protective film, a transparent PET substrate and a transparent fluorine film.
[0010] By adopting the above technical solution, the use of transparent fluorine film enhances the light transmittance and strength of the explosion-proof film layer, so that the explosion-proof film layer enhances the protective performance of the explosion-proof film of the mobile phone lens while enhancing the light transmittance of the explosion-proof film of the mobile phone lens.
[0011] Preferably, the other side surface of the transparent protective film is bonded to the surface of the transparent PET substrate, the other end surface of the transparent PET substrate is bonded to one end surface of the transparent fluorine film, and the other end surface of the transparent fluorine film is bonded to the AB glue bracket.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like 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 it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. 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. Figure 1 and attached Figure 2 This application is described in further detail.
[0037] The present application discloses an explosion-proof film for a mobile phone lens. Figure 1The explosion-proof film for mobile phone lens includes a glass layer 1 and an AB glue bracket 3. The glass layer 1 is located at the outermost layer of the mobile phone lens and can provide basic anti-scratch function; the AB glue bracket 3 is used to directly fit with the mobile phone lens. The glass layer 1 is provided with an explosion-proof film layer 2. The surface of the glass layer 1 and the surface of the explosion-proof film layer 2 are combined with glue, and the AB glue bracket 3 and the other surface of the explosion-proof film layer 2 are also combined with glue. The explosion-proof film layer 2 can absorb and disperse the impact force to prevent the mobile phone lens from being damaged when impacted, thereby enhancing the strength of the mobile phone lens, better protecting the mobile phone lens film, and enhancing the protective performance of the mobile phone lens explosion-proof film.
[0038] Specifically, the thickness of the glass layer 1 ranges from 0.25mm to 0.38mm. In the embodiment of the present application, the thickness of the glass layer 1 is preferably 0.30mm. Compared with the glass layer 1 having a thickness range of 0.25mm, the glass layer 1 having a thickness of 0.30mm has better impact resistance and can enhance the explosion-proof effect of the mobile phone lens film; compared with the glass layer 1 having a thickness range of 0.38mm, the glass layer 1 has improved light transmittance and improved imaging quality. At the same time, it is convenient to stick or install the glass layer 1 on the explosion-proof film layer 2.
[0039] It is worth noting that the end face of the glass layer 1 is a curved surface, which makes it safer for the user to touch the glass layer 1 when holding the mobile phone, thereby enhancing the safety performance of the explosion-proof film of the mobile phone lens.
[0040] Reference Figure 1 The explosion-proof film layer 2 includes a transparent protective film, a transparent PET substrate and a transparent fluorine film. One surface of the transparent protective film is combined with the glass film by glue. The other surface of the transparent protective film is fixedly bonded to the surface of the transparent PET substrate. The other surface of the transparent PET substrate is fixedly bonded to one end face of the transparent fluorine film. The other surface of the transparent fluorine film is bonded to the AB glue bracket 3. The explosion-proof film layer 2 adopts a transparent PET substrate. The transparent PET substrate has excellent transparency and smoothness, so that a clear visual effect can be provided. The use of the transparent fluorine film enhances the light transmittance and strength of the explosion-proof film layer 2, so that the explosion-proof film layer 2 enhances the protective performance of the mobile phone lens explosion-proof film while enhancing the light transmittance of the mobile phone lens explosion-proof film.
[0041] Reference Figure 1The AB glue bracket 3 includes an acrylic layer and an AB glue layer, the surface of the acrylic layer is bonded to the surface of the transparent fluorine film, and the other surface of the acrylic layer is bonded to the surface of the back panel of the mobile phone. The acrylic layer can enhance the overall toughness and impact resistance, and further enhance the protective performance of the mobile phone lens protective film. The AB glue layer can provide stable viscosity to ensure that the mobile phone lens protective film fits tightly to the lens. It is worth noting that the AB glue layer is provided with a back panel layer, and the AB glue layer is detachably connected to the back panel layer. The main function of the back panel layer is to provide adhesion and support, prevent the glue layer from deforming and changing in viscosity, so that the protective film can fit tightly on the mobile phone lens.
[0042] Reference Figure 2 , the AB glue bracket 3 is provided with a lens hole 31 at the corresponding position of the mobile phone lens. The mobile phone lens can ensure the camera function, and the lens hole 31 is provided to ensure that the camera can capture images normally. In this embodiment, the width of the lens hole 31 is the same as the width of the mobile phone lens. Ensure that the lens can be illuminated normally, thereby ensuring the imaging quality of the mobile phone camera. The glass layer 1, the explosion-proof film layer 2 and the AB glue bracket 3 are provided with a flash hole 31 at the corresponding position of the mobile phone flash. In this embodiment of the application, the side of the flash hole 31 away from the mobile phone lens is set as the outer side, and the side of the flash hole 31 close to the mobile phone lens is set as the inner side. The inner width of the flash hole 31 is equal to the width of the flash; the outer width of the flash hole 31 is greater than the inner width of the flash hole 31, and the hole wall of the flash hole 31 is continuous. The light emitted by the flash is better diffused, making the mobile phone lighting more uniform.
[0043] It is worth noting that the glass layer 1, the explosion-proof film layer 2 and the AB glue bracket 3 are penetrated with noise reduction holes 33. The diameter of the noise reduction hole 33 ranges from 2.0mm to 2.8mm. In the embodiment of the present application, the diameter of the noise reduction hole 33 is 2.6mm. Compared with 2.4mm, the noise reduction hole 33 with a width of 2.6mm is less difficult to make and has a lower cost; compared with 2.8mm, the noise reduction hole 33 with a width of 2.6mm can make the structure of the mobile phone lens film more complete and further enhance the stability of the structure of the mobile phone lens film.
[0044] The implementation principle of the embodiment of the present application is: adding an explosion-proof film layer 2 between the glass layer 1 and the AB glue bracket 3 to further enhance the strength and protective performance of the explosion-proof film of the mobile phone. The explosion-proof film layer 2 includes a transparent protective film, a transparent PET substrate and a transparent fluorine film. The transparent PET substrate is used. The transparent PET substrate has excellent transparency and smoothness, so that a clear visual effect can be provided. The use of the transparent fluorine film enhances the light transmittance of the explosion-proof film layer 2 while enhancing the strength of the mobile phone lens protective film.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
