Abstract
Description
Technical Field
[0001] This utility model relates to the field of tempered glass film technology, specifically to a tempered glass film with high protective effect. Background Technology
[0002] In today's digital age, portable electronic devices such as smartphones, tablets, and smartwatches have become deeply integrated into people's work, life, and entertainment. The screens of these devices, as the core carriers of information display and user interaction, directly impact the user experience in terms of their integrity and lifespan. However, during daily carrying and use, electronic devices inevitably encounter various unexpected situations, such as slipping from pockets or desks, rubbing against hard objects like keys or coins while placed in a bag, or accidentally colliding with other objects during use. These situations can easily lead to scratches, cracks, or even breakage of the screen, not only affecting the normal use of the device but also potentially requiring expensive repairs, causing considerable inconvenience and loss for users. Therefore, equipping electronic devices with effective screen protection products to reduce the risk of screen damage has become a common need for many users.
[0003] Among numerous screen protector products, tempered glass screen protectors have captured the mainstream market due to their significant advantages. Tempered glass screen protectors are made by subjecting ordinary glass to special chemical or physical treatments, creating compressive stress on its surface and resulting in high surface hardness, typically reaching a Mohs hardness of 6-7. This effectively resists minor scratches from daily use, reducing the likelihood of screen damage. Simultaneously, tempered glass screen protectors offer excellent light transmittance, generally exceeding 90%, ensuring minimal impact on screen display quality and allowing users to clearly view screen content. Furthermore, tempered glass screen protectors are relatively easy to install, have a high degree of fit, and do not significantly affect the device's touch sensitivity. Therefore, they are widely favored by consumers and have become the preferred solution for protecting electronic device screens.
[0004] However, despite the numerous advantages mentioned above, tempered glass screen protectors still have significant shortcomings in their protective performance during practical applications. Traditional tempered glass screen protectors are often designed with exposed edges, lacking additional protection. This design significantly reduces their protective capabilities in certain situations. For example, when an electronic device is accidentally dropped, the edges often hit the ground first, directly absorbing the impact force. Similarly, when the device is struck from the edges, the stress is more concentrated at the edges. In these cases, the edges of the tempered glass screen protector are prone to shattering. Once the edges shatter, it not only loses its protective function for the corresponding area of the electronic device screen, exposing the screen to a potentially damaging environment, but the sharp shards from the shattered glass can also cut the user's fingers, posing a safety hazard. Utility Model Content
[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A tempered glass screen protector body, the tempered glass screen protector body being used to cover the screen of an electronic device;
[0008] A protective edge structure is provided at the edge of the tempered glass film body. The protective edge structure includes a buffer layer and a hard layer. The buffer layer wraps around the side of the tempered glass film body, and the hard layer is provided on the outside of the buffer layer, with the outer surface of the hard layer flush with the outer surface of the tempered glass film body.
[0009] A functional coating is applied to the surface of the tempered glass body, and the functional coating includes one or more of an anti-blue light coating, an oleophobic coating, and an anti-fingerprint coating.
[0010] As a further embodiment of this invention, the buffer layer is an elastic rubber layer or a silicone layer.
[0011] As a further embodiment of this utility model, the material of the hard layer is a metal material or a high-strength engineering plastic.
[0012] As a further embodiment of this utility model: an electrostatic adsorption layer is provided on the side of the tempered glass film body close to the screen of the electronic device, and the electrostatic adsorption layer is closely attached to the tempered glass film body.
[0013] As a further embodiment of this utility model: the buffer layer surrounds the periphery of the tempered glass film body to form a flexible frame acting on the tempered glass film body, and there is a first gap between the flexible frame and the tempered glass film body, and a first adhesive layer is disposed in the first gap.
[0014] As a further embodiment of this utility model: the rigid layer surrounds the periphery of the flexible frame to form a rigid frame acting on the tempered film body, and there is a second gap between the rigid frame and the flexible frame, and a second adhesive layer is disposed in the second gap.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] When electronic devices are subjected to external impacts, especially when the edges are hit or dropped, the buffer layer in the protective edge structure can absorb part of the impact force through its own elastic deformation, dispersing the concentrated external force to a larger area and reducing the force transmitted to the edge of the tempered glass screen protector. The rigid layer, with its own structural strength, supports the buffer layer, limits the excessive deformation of the buffer layer, and prevents the buffer layer from failing due to excessive deformation. At the same time, it directly resists some of the impact force from the outside, thereby reducing the possibility of the edge of the tempered glass screen protector breaking.

[0023] 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.
[0024] Please see Figure 1-2 In this embodiment of the present invention, a tempered glass film with high protective effect has a structure comprising a tempered glass film body 1, a protective edge structure, and a functional coating 4.
[0025] The tempered glass screen protector body 1 is made of reinforced glass with a polished surface and smooth edges to avoid sharp corners. The size of the tempered glass screen protector body 1 matches the screen of the compatible electronic device, completely covering the display area and edges, providing basic scratch protection. On the side of the tempered glass screen protector body 1 closest to the screen, there is an electrostatic adsorption layer 5. This layer adheres tightly to the inner surface of the tempered glass screen protector body 1, with its coverage area matching the inner surface. The electrostatic adsorption layer 5 is made of a material with electrostatic adsorption properties, exhibiting a uniform, slightly adhesive surface. This allows the tempered glass screen protector to adhere stably to the screen without glue, and it can be easily peeled off without leaving any residue, facilitating subsequent removal and replacement.
[0026] The protective edge structure is located at the edge of the tempered glass screen protector body 1, continuously distributed along the outer periphery of the tempered glass screen protector body 1, and consists of a buffer layer 2 and a rigid layer 3. The buffer layer 2 surrounds the periphery of the tempered glass screen protector body 1, forming a flexible frame acting on the tempered glass screen protector body 1. Its width is adapted to the edge thickness of the tempered glass screen protector body 1, completely covering the side of the tempered glass screen protector body 1. The buffer layer 2 is made of elastic rubber or silicone material, with a dense internal structure and a certain elastic deformation capacity. It can deform when subjected to external pressure and can return to its original shape after the external force is removed. There is a first gap between the buffer layer 2 and the tempered glass screen protector body 1. This gap is evenly distributed along the edge of the tempered glass screen protector body 1, and the width is consistent. A first adhesive layer 6 is provided in the first gap. The first adhesive layer 6 completely fills the first gap. Through the adhesive effect of the first adhesive layer 6, the buffer layer 2 and the tempered glass screen protector body 1 are fixedly connected, and there is no obvious protrusion or depression at the connection point.
[0027] A rigid layer 3 is disposed on the outside of the buffer layer 2, surrounding the periphery of the flexible frame, forming a rigid frame acting on the tempered glass film body 1. Its shape matches the outer periphery of the buffer layer 2, completely covering the outer surface of the buffer layer 2. The rigid layer 3 is made of metal or high-strength engineering plastic, possessing high structural strength and being resistant to deformation. A second gap exists between the rigid layer 3 and the flexible frame, which is also evenly distributed along the edge of the buffer layer 2, with a width similar to the first gap. A second adhesive layer 7 is disposed within the second gap, completely filling it. Through the adhesive effect of the second adhesive layer 7, the rigid layer 3 and the buffer layer 2 are firmly connected, forming a unified structure. The outer surface of the rigid layer 3 is flattened, lying on the same plane as the outer surface of the tempered glass film body 1, ensuring that the overall edge of the tempered glass film remains flat, without noticeable steps when touched. This results in a smooth overall surface for the tempered glass film, improving aesthetics and preventing dust accumulation caused by uneven surfaces.
[0028] In one embodiment, the first adhesive layer 6 and the second adhesive layer 7 can be directly bonded with glue, thereby connecting and fixing the buffer layer 2 to the tempered film body 1 and the hard layer 3 to the buffer layer 2 respectively.
[0029] In one embodiment, during the manufacturing process, to ensure the accurate relative positions of the buffer layer 2, the hard layer 3, and the tempered glass film body 1, a mold or fixture adapted to the dimensions of the tempered glass film body 1, the buffer layer 2, and the hard layer 3 are used for positioning. After positioning, adhesive material is injected into the first gap and the second gap using a dispensing process. After the adhesive material cures, a first adhesive layer 6 and a second adhesive layer 7 are formed.
[0030] Functional coating 4 covers the outer surface of the tempered glass screen protector body 1, with a coverage area consistent with the outer surface of the tempered glass screen protector body 1 and a uniform thickness. Functional coating 4 includes one or more of the following: anti-blue light coating, oleophobic coating, and anti-fingerprint coating, which can be combined according to actual usage requirements. The anti-blue light coating absorbs or reflects blue light of a specific wavelength, reducing the amount of blue light of that wavelength passing through the tempered glass screen protector body 1 and entering the human eye; the oleophobic coating changes the surface tension of the outer surface of the tempered glass screen protector body 1, making it difficult for grease to adhere to its surface, and even if a small amount of grease is present, it can be easily wiped away; the anti-fingerprint coating forms a smooth film on the surface, reducing the adhesion of fingerprints and sweat to the surface, and reducing the retention of fingerprints on the surface.
[0031] When electronic devices are subjected to external impacts, especially collisions or drops to the edges, the buffer layer 2 in the protective edge structure can absorb part of the impact force through its own elastic deformation, dispersing the concentrated external force to a larger area and reducing the force transmitted to the edge of the tempered glass screen protector 1. The rigid layer 3, with its own structural strength, supports the buffer layer 2, limiting excessive deformation of the buffer layer 2 and preventing it from failing due to excessive deformation. It also directly resists some of the impact force from the outside, thereby reducing the possibility of the edge of the tempered glass screen protector 1 cracking. The presence of the functional coating 4 allows the tempered glass screen protector to meet user needs in specific usage scenarios beyond its basic protective functions, such as reducing blue light exposure during prolonged use of electronic devices and reducing the frequency of cleaning oil stains and fingerprints during daily use. The electrostatic adsorption layer 5 ensures a stable fit between the tempered glass screen protector and the electronic device screen, preventing lifting or detachment during daily use, and does not affect the screen's display effect or touch sensitivity, nor does it damage the screen.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
