Description

Technical Field

[0001] This utility model relates to the field of tempered glass film technology, specifically a tempered glass film structure with four curved edges for protection. Background Technology

[0002] Tempered glass is a type of safety glass. It has excellent wear resistance and is very hard, with a Vickers hardness of 622 to 701. Tempered glass is actually a prestressed glass. To improve its strength, chemical or physical methods are usually used to create compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. Tempered glass screen protectors provide a high level of safety protection for mobile phone screens. Mobile phone touchscreens come in various shapes, including those with flat curved edges on all four sides and those with curved edges on all four sides. Tempered glass screen protectors need to be molded to perfectly match the different styles of mobile phones.

[0003] According to the tempered glass film for a curved screen mobile phone disclosed in patent publication number CN208008712U, it includes a first tempered glass layer, a second tempered glass layer disposed above the first tempered glass layer, and an explosion-proof adhesive layer disposed on the lower surface of the first tempered glass layer; a plurality of micro-grooves are evenly distributed on the upper surface of the first tempered glass layer.

[0004] Although the aforementioned patent provides an explosion-proof adhesive layer on the lower surface of the first tempered glass layer, thus achieving explosion-proof and crack-proof effects, the tempered glass can usually withstand the impact and protect the phone when it is dropped horizontally from the front. However, when the phone is dropped from the side or from the four corners towards the ground, the simple explosion-proof adhesive layer cannot provide adequate protection. Therefore, we address this issue by using a tempered film structure with curved edges on all four sides. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a tempered membrane structure with four curved edges that can solve the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tempered glass film structure with four curved edges, comprising a tempered glass film assembly, wherein a first outer film assembly is provided on the upper end surface of the tempered glass film assembly, and a second outer film assembly is provided on the lower end surface of the tempered glass film assembly;

[0007] The tempered glass film assembly includes a protective layer, a tempered glass main film, and a bottom film. A protective component is bonded to the lower ends of the protective layer, the tempered glass main film, and the bottom film. The protective layer is disposed on the upper end surface of the tempered glass main film, and the bottom film is bonded to the lower end surface of the tempered glass main film.

[0008] As a further embodiment of this utility model: the protective component includes a protective frame strip bonded to the lower perimeter of the protective layer, the tempered glass main film and the bottom film. The lower end of the protective frame strip is provided with two sets of buffer cavities. The lower end of the protective frame strip is bonded with a central film, an outer film and an inner film. The protective frame strip is made of rubber material.

[0009] As a further embodiment of this utility model: the first outer membrane assembly includes an upper protective film adhered to the upper end of the protective layer, and upper tear strips are integrally connected to both sides of the upper protective film.

[0010] As a further embodiment of this utility model: the second outer membrane assembly includes a lower protective film adhered to the lower end of the bottom membrane, and both sides of the lower protective film are integrally connected with a lower tear strip.

[0011] As a further embodiment of this utility model: the protective layer includes an anti-radiation coating applied to the upper end of the tempered glass main film, an anti-blue light coating applied to the upper surface of the anti-radiation coating, and a nano-oleophobic layer applied to the upper surface of the anti-blue light coating.

[0012] As a further embodiment of this utility model: the central membrane, outer membrane and inner membrane are all made of PET material.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When a phone is dropped from the side or from any of its four corners, the tempered glass screen protector is impacted first, and then the impact force is fed back to the protective frame. The protective frame, made of rubber, provides effective cushioning and protection, preventing the tempered glass screen protector from directly transmitting the impact force to the phone, which could easily cause the screen to shatter. Furthermore, the two sets of buffer cavities at the bottom of the protective frame further compress and buffer the impact force, effectively improving the protection of the phone screen and thus enhancing the performance of this tempered glass screen protector structure.

[0015] 2. The upper and lower protective films effectively protect both ends of the tempered glass screen protector assembly from dust. The lower protective film is torn off from the bottom of the tempered glass screen protector assembly via a tear strip. However, this tearing process can cause fingers to come into contact with the bottom film of the tempered glass main film, easily leaving dirt and affecting the screen protector's performance. Furthermore, when applying the tempered glass screen protector assembly, there is a slight tilt, requiring angle adjustment. Users can pull the two upper tear strips left and right to adjust the tilt angle of the upper protective film and the tempered glass screen protector assembly below it. This effectively prevents fingers from coming into contact with the bottom film of the tempered glass screen protector assembly, leaving fingerprints and dirt, thus improving the overall performance.

[0016] 3. The nano-oleophobic layer designed on the top of the tempered glass main film makes it less prone to fingerprints, making cleaning easier. At the same time, due to the special properties of the nano-oleophobic layer material, it makes finger touch smoother, without any resistance or sluggish operation, improving the user experience and enhancing the overall performance. The designed anti-radiation coating and anti-blue light coating effectively protect the user's eyes from radiation and blue light when using the phone, further improving the performance.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A tempered glass film structure with four curved edges includes a tempered glass film assembly 2. A first outer film assembly 1 is provided on the upper end surface of the tempered glass film assembly 2. The first outer film assembly 1 includes an upper protective film 11 bonded to it. Both sides of the upper protective film 11 are integrally connected with upper tear strips 12. A second outer film assembly 3 is provided on the lower end surface of the tempered glass film assembly 2. The second outer film assembly 3 includes a lower protective film 31 bonded to the lower end of a bottom film 23. Both sides of the lower protective film 31 are integrally connected with lower tear strips 32.

[0026] The tempered glass assembly 2 is protected by the upper protective film 11 and the lower protective film 31. Effective dust protection is provided at both ends of the tempered glass screen protector assembly 2. When applying the screen protector to the phone, the lower protective film 31 is torn off from the bottom of the tempered glass screen protector assembly 2 using the lower tear strip 32. This avoids the situation where the traditional tempered glass screen protector dustproof film is the same size as the tempered glass screen protector body, which would cause fingers to come into contact with the tempered glass screen protector body when tearing the film, easily leaving dirt on the tempered glass screen protector body and affecting the use effect of the tempered glass screen protector. When the tempered glass screen protector assembly 2 is applied, there is a slight tilt, and the angle needs to be adjusted. The user can pull the two upper tear strips 12 left and right to facilitate the upper tear strips 12 to move the upper protective film 11 and the tempered glass screen protector assembly 2 at the bottom to adjust the tilt angle. This effectively avoids the fingers coming into contact with the tempered glass screen protector assembly 2 body and easily coming into contact with the bottom film 23 of the tempered glass screen protector assembly 2, leaving fingerprints and dirt, affecting the use effect of the tempered glass screen protector assembly 2. After the tempered glass screen protector assembly 2 is applied, the upper protective film 11 is torn off from the top of the tempered glass screen protector assembly 2 using the upper tear strip 12 for convenient use.

[0027] The tempered glass film assembly 2 includes a protective layer 21, a tempered glass main film 22, and a bottom film 23. The bottom film 23 is bonded to the lower end of the tempered glass main film 22. The bottom film 23 is bonded to the lower end of the tempered glass main film 22. A protective component 24 is bonded to the lower ends of the protective layer 21, the tempered glass main film 22, and the bottom film 23. The protective component 24 includes a protective frame strip 241 bonded around the lower ends of the protective layer 21, the tempered glass main film 22, and the bottom film 23. Two sets of buffer cavities 243 are provided at the lower end of the protective frame strip 241. A central film 242, an outer film 244, and an inner film 245 are bonded to the lower end of the protective frame strip 241. The protective frame strip 241 is made of rubber material, while the central film 242, the outer film 244, and the inner film 245 are all made of PET material.

[0028] After the bottom film 23 of the tempered glass screen protector assembly 2 is bonded to the curved edges of the mobile phone touchscreen, the protective layer 21, the tempered glass main film 22, and the protective component 24 at the lower end of the bottom film 23 are pressed against the curved edges of the mobile phone touchscreen. Meanwhile, the PET material core film 242, outer film 244, and inner film 245 of the protective component 24 are bonded to the curved edges of the mobile phone touchscreen in a partitioned manner, improving the bonding effect. When the phone is dropped from the side or from any of its four corners towards the ground, the tempered glass... When the tempered glass main film 22 is impacted, the impact force is fed back to the protective frame strip 241. The protective frame strip 241, made of rubber material, provides effective buffering protection, preventing the tempered glass main film 22 from directly feeding back the impact force to the mobile phone, which could easily cause the mobile phone screen to shatter. Furthermore, by designing two sets of buffer cavities 243 at the lower end of the protective frame strip 241, the impact force is further compressed and buffered, effectively improving the protection effect of the mobile phone screen and thus enhancing the performance of this tempered glass screen protector structure.

[0029] The protective layer 21 is disposed on the upper surface of the tempered glass main film 22. The protective layer 21 includes an anti-radiation coating 213 applied to the upper surface of the tempered glass main film 22, an anti-blue light coating 212 applied to the upper surface of the anti-blue light coating 213, and a nano oleophobic layer 211 applied to the upper surface of the anti-blue light coating 212.

[0030] The nano oleophobic layer 211 designed on the upper part of the tempered glass main film 22 makes it less likely to leave fingerprints on the surface of the tempered glass main film 22, making cleaning easier. At the same time, due to the special material of the nano oleophobic layer 211, it makes finger touch smoother, without any obstruction or unsmooth operation, improving the user experience and enhancing the usability. The designed anti-radiation coating 213 and anti-blue light coating 212 effectively protect the user's eyes from radiation and blue light when using the mobile phone, improving the usability.

[0031] Working Principle: This invention effectively protects both ends of the tempered glass screen protector assembly 2 from dust using an upper protective film 11 and a lower protective film 31. When applying the screen protector to the tempered glass screen protector assembly 2, the lower protective film 31 is torn off from the bottom of the tempered glass screen protector assembly 2 using the lower tear strip 32. This avoids the situation where the dustproof protective film of the traditional tempered glass screen protector is the same size as the tempered glass screen protector body, causing fingers to come into contact with the tempered glass screen protector body during tearing, which can easily leave dirt on the tempered glass screen protector body and affect the use effect of the tempered glass screen protector. When the tempered glass screen protector assembly 2 is slightly tilted during application and the angle needs to be adjusted, the user can pull the two upper tear strips 12 left and right to move them, making it easier for the upper tear strips 12 to move the upper protective film 11 and the lower end of the tempered glass screen protector assembly 2. The tempered glass screen protector assembly 2 is tilted at an adjustable angle to effectively prevent fingers from coming into contact with the body of the tempered glass screen protector assembly 2 and from easily coming into contact with the bottom film 23 of the tempered glass screen protector assembly 2, which would leave fingerprints and dirt and affect the performance of the tempered glass screen protector assembly 2. After the tempered glass screen protector assembly 2 is applied, the upper protective film 11 can be torn off from the top of the tempered glass screen protector assembly 2 using the upper tear strip 12 for easy use. After the bottom film 23 of the tempered glass screen protector assembly 2 is attached to the curved edges of the mobile phone touch screen, the PET material of the protective assembly 24, including the central film 242, outer film 244, and inner film 245, separates the screen protector from the mobile phone touch screen. The screen's four curved edges are bonded together. When the phone is dropped from the side or from one of its four corners, the tempered glass main film 22 is impacted first, and then the impact force is fed back to the protective frame strip 241. The rubber protective frame strip 241 provides effective cushioning protection, preventing the tempered glass main film 22 from directly feeding back the impact force to the phone, which could easily cause the screen to shatter. Furthermore, the two sets of buffer cavities 243 at the lower end of the protective frame strip 241 further compress and buffer the impact force, effectively reducing its impact and improving the protection against damage. The screen protection is enhanced, thus improving the usability of this tempered glass screen protector. The nano-oleophobic layer 211 designed on the upper part of the tempered glass main film 22 makes it less prone to fingerprints, making cleaning easier. Furthermore, due to the special properties of the nano-oleophobic layer 211, finger touch is smoother, eliminating any resistance or operational difficulties, thus improving the user experience and enhancing usability. The designed anti-radiation coating 213 and anti-blue light coating 212 effectively protect the user's eyes from radiation and blue light while using the phone, further improving the overall usability.
