Description

Technical Field

[0001] This utility model relates to the field of tempered glass screen protector technology, and in particular to a mobile phone tempered glass screen protector with a multi-layered structure. Background Technology

[0002] Tempered glass screen protectors are transparent protective films commonly used to protect the screens of electronic devices. They are primarily made of glass and undergo a special chemical treatment process to significantly increase their surface hardness, resulting in higher scratch resistance and impact resistance than ordinary plastic screen protectors. This type of film effectively prevents the screens of devices such as mobile phones and tablets from scratches or damage from accidental drops.

[0003] With the continuous development of smartphone technology, more and more phones are adopting screen designs with curved edges, such as 2.5D curved edge screens and curved screens. This design not only improves the aesthetics and grip of the phone, but also provides a wider field of view. However, this curved edge design also brings new challenges to the screen protection effect of tempered glass screen protectors. Since existing tempered glass screen protectors cannot provide effective protection, some tempered glass screen protectors with curved edge structures have appeared on the market, but the protection effect of these products is still unsatisfactory. For example, when tempered glass screen protectors with curved edge structures are applied to the screen, they are more susceptible to bumps and knocks in daily use. Once a crack appears in the curved edge structure, the crack often spreads rapidly, causing the entire tempered glass screen protector to fail, or even damaging the screen.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tempered glass screen protector for mobile phones with a multi-layer structure, comprising a tempered glass layer, an adhesive layer provided on the lower end face of the tempered glass layer, and a pair of arc-shaped edges formed on the edge of the tempered glass layer, wherein the pair of arc-shaped edges are symmetrically arranged on both sides of the tempered glass layer.

[0007] Flexible protective strips are provided on the opposite edges of the pair of arc-shaped edges. The flexible protective strips have cavities inside, and reinforced edges are provided inside the cavities.

[0008] As a further embodiment of this utility model: the flexible protective strip has an indented structure on the side facing the arc-shaped edge that matches the arc surface of the arc-shaped edge.

[0009] As a further embodiment of this utility model: the contact surface between the arc-shaped edge and the flexible protective strip has a rough layer;

[0010] Alternatively, the contact surface between the flexible protective strip and the arc-shaped edge has a rough layer.

[0011] As a further embodiment of this utility model, the protective strip is made of silicone material.

[0012] As a further embodiment of this invention, the reinforcing edge is made of carbon fiber.

[0013] As a further embodiment of this utility model: the upper surface of the tempered glass layer is coated with an anti-fingerprint coating.

[0014] Compared with existing technologies, the beneficial effects of this technical solution are as follows: the tempered glass layer and the curved edges on both sides protect the mobile phone screen, and the flexible protective strip made of silicone absorbs a large amount of impact energy when the curved edges are bumped or hit. At the same time, the structural strength of the flexible protective strip is enhanced by setting a reinforcing edge made of carbon fiber inside the flexible protective strip, providing additional support when the flexible protective strip is subjected to external impact, and maintaining the integrity of the overall structure. Thus, the flexible protective strip absorbs the impact force when bumped or hit, and the internal reinforcing edge enhances the structural strength. The combination of the two maximizes the protective effect.

[0015] Secondly, the addition of reinforced edges allows the flexible protective strip to maintain high structural strength and stability even when bent, preventing deformation and warping, thus extending the service life of the flexible protective strip.

[0016] Furthermore, the roughened surfaces created by frosting the flexible protective strip and the curved edge can significantly increase the friction between them, increase the contact area of ​​the adhesive, improve the bonding effect, and make the flexible protective strip more firmly fixed to the curved edge, thereby improving the overall stability and durability.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[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 1-3 A tempered glass screen protector for mobile phones with a multi-layer structure includes a tempered glass layer 1, an adhesive layer 2 disposed on the lower end face of the tempered glass layer 1, and a pair of arc-shaped edges 3 formed on the edge of the tempered glass layer 1, with the pair of arc-shaped edges 3 symmetrically disposed on both sides of the tempered glass layer 1.

[0026] A pair of curved edges 3 have flexible protective strips 4 on opposite sides. The flexible protective strips 4 have cavities inside, and reinforced edges 5 are provided inside the cavities.

[0027] In this invention, the phone screen is first cleaned to ensure no dust residue remains. Then, a tempered glass film is attached to the screen surface using an adhesive layer 2. The tempered glass layer 1 and the curved edges 3 on both sides of the tempered glass layer 1 protect the phone screen. During daily use, the user can utilize the flexible protective strip 4 on the curved edges 3 for protection. The flexible protective strip 4 is made of flexible material and is adhered to the curved edges 3. When the curved edges 3 are bumped or impacted, the flexible protective strip 4 can effectively absorb the impact energy, protecting the curved edges 3, i.e., the edges of the tempered glass layer 1, and preventing the curved edges 3 from being bumped or impacted. To address the shortcomings of existing tempered glass screen protectors in terms of protection, this design provides more comprehensive protection for phones with curved screens, improving the lifespan and protective effect of the screen protector. Secondly, a reinforcing edge 5 is incorporated into the internal cavity of the flexible protective strip 4. This reinforcing edge 5 enhances the structural strength of the flexible protective strip 4, providing additional support when subjected to external impacts, thus maintaining the integrity of the overall structure and further preventing damage to the curved edge 3 of the tempered glass screen protector. This achieves the combined effect of absorbing the impact force of bumps and knocks with the flexible protective strip 4, and strengthening the structure with the internal reinforcing edge 5, maximizing the protective effect.

[0028] Preferably, a release film can be added to the lower surface of the adhesive layer 2 to protect the adhesive layer 2. When it is necessary to attach the mobile phone, the release film can be peeled off, which can avoid affecting the adhesiveness of the adhesive layer 2. The adhesive layer 2 is made of OCA material.

[0029] In a preferred embodiment of the present invention, the flexible protective strip 4 completely wraps around the reinforcing edge 5, so that the reinforcing edge 5 and the arc-shaped edge 3 are separated by the flexible protective strip 4, which can prevent the reinforcing edge 5 from colliding with the arc-shaped edge 3. The flexible protective strip 4 can play a buffering and protective role between the reinforcing edge 5 and the arc-shaped edge 3, further preventing damage to the arc-shaped edge 3.

[0030] In this embodiment of the invention, the flexible protective strip 4 is made of silicone material. Silicone has excellent flexibility and can adapt well to the curvature of the screen, ensuring that the tempered glass film fits tightly at the edge. It can also quickly return to its original shape after being subjected to external force and is not easily deformed. This helps to maintain the long-term fit and stability of the tempered glass film.

[0031] In the embodiments of this utility model, the reinforcing edge 5 is made of carbon fiber. Carbon fiber has high strength and rigidity, which allows the addition of the reinforcing edge 5 to maintain high structural strength and stability of the flexible protective strip 4 in a bent state. This avoids deformation and warping of the flexible protective strip 4, which would prevent it from fitting properly to the mobile phone screen and allow dust and other impurities to remain and enter the screen. This achieves the effect of extending the service life of the flexible protective strip 4.

[0032] Meanwhile, the reinforced edge 5, made of carbon fiber, is lightweight yet strong, achieving the effect of improving the strength and performance of the flexible protective strip 4 without adding too much weight, thus enhancing user comfort.

[0033] In an embodiment of this utility model, the flexible protective strip 4 has an indented structure on the side facing the arc-shaped edge 3 that matches the arc surface of the arc-shaped edge 3.

[0034] Specifically, by setting an indented structure on the flexible protective strip 4 that matches the curvature of the arc-shaped edge 3, it can be ensured that the flexible protective strip 4 and the arc-shaped edge 3 fit tightly together, thus preventing the flexible protective strip 4 from falling off.

[0035] Furthermore, the contact surface between the arc-shaped edge 3 and the flexible protective strip 4 has a rough layer 6;

[0036] Alternatively, the contact surface between the flexible protective strip 4 and the arc-shaped edge 3 has a rough layer 6, and the rough surface is formed by a sanding process.

[0037] Specifically, when the flexible protective strip 4 is bonded to the curved edge 3, the rough layer 6 can significantly increase the friction between the flexible protective strip 4 and the curved edge, increase the contact area of ​​the adhesive, improve the bonding effect, and make the flexible protective strip 4 more firmly fixed to the curved edge 3, thereby improving the overall stability and durability.

[0038] In this embodiment of the invention, the upper surface of the tempered glass layer 1 is coated with an anti-fingerprint coating 7.

[0039] The anti-fingerprint coating 7 can effectively reduce the adhesion of fingerprints on the tempered glass layer 1, keeping the surface of the tempered glass layer 1 clean.

[0040] 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 illustrative 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
