[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] Please refer to Figures 1-3 , a high corner resistance tempered film, comprising a tempered glass layer 1, the lower end of the tempered glass layer 1 is provided with a first glue layer 2, the lower end of the first glue layer 2 is provided with a release film 3, when the tempered film is attached to the screen of a device (such as a mobile phone), the surface of the screen is first cleaned by using tools such as alcohol cotton and dust paste to ensure that there is no dust on the surface of the screen, then the release film 3 is removed, then the tempered glass layer 1 is placed after being aligned with the screen, the tempered glass layer 1 is fixed on the screen by using the first glue layer 2, and the tempered glass layer 1 provides protection for the screen.
[0026] The lower end surface of the tempered glass layer 1 is provided with embedded grooves 4 at the four corners, the embedded grooves 4 are embedded with protective blocks 5, one side of the protective blocks 5 is provided with protective frames 6, the inner side of the protective frames 6 is attached to the outer side of the corners of the tempered glass layer 1 to form protection for the corners of the tempered glass layer 1.
[0027] Specifically, the protective blocks 5 and the protective frames 6 form a wrapped protection structure for the corners of the tempered glass layer 1, which can absorb the impact force on the corners when the device falls, thereby improving the impact resistance of the corners of the tempered film, reducing the occurrence of corner breakage and damage of the tempered film, and achieving the effect of improving the service life of the tempered film.
[0028] Among them, the embedded grooves 4 at the four corners of the lower end surface of the tempered glass layer 1 are cut by CNC technology, the protective blocks 5 are embedded in the embedded grooves 4, the embedded grooves 4 provide accurate installation positions for the protective blocks 5, greatly improving the convenience and accuracy of installation, which can ensure that the protective blocks 5 are closely attached to the corners of the tempered glass layer 1, avoiding the situation that the frame is installed skewed or deviated in position;
[0029] Preferably, the protective block 5 and the protective frame 6 are both made of TPU material. When a collision occurs, the TPU material can absorb the impact force through elastic deformation, thereby reducing the impact of the impact force on the corners of the tempered glass layer 1. The protective block 5 is arranged at the lower end of the tempered glass layer 1. When the corners of the tempered glass layer 1 are subjected to pressure, the protective block 5 can absorb the pressure to prevent the corners of the tempered glass layer 1 from being pressed and breaking. The protective frame 6 is arranged on the side of the corners of the tempered glass layer 1. When the device falls and the corners touch the ground first, the protective frame 6 can absorb and buffer the impact force on the corners. In summary, the combination of the protective block 5 and the protective frame 6 made of TPU material can provide multi-directional buffering protection for the corners of the tempered glass layer 1, thereby improving the protection effect on the corners.
[0030] In some embodiments, the protective block 5 and the protective frame 6 are integrally formed. The integrally formed protective block 5 and protective frame 6 have high stability and can better and continuously protect the corners of the tempered glass layer 1.
[0031] In some embodiments, the contact surfaces of the protective block 5 and the protective frame 6 with the tempered glass layer 1 are provided with a second adhesive layer 7.
[0032] Specifically, the second adhesive layer 7 is made of PUA adhesive to ensure that the protective block 5 and the protective frame 6 are firmly attached to the tempered glass layer 1. In addition, due to the design of the embedded groove 4, the contact area of the protective block 5 with the tempered glass layer 1 can be greatly increased, thereby further improving the firmness and stability of the adhesion.
[0033] In some embodiments, the upper end of the protective frame 6 is higher than the upper end surface of the tempered glass layer 1 and forms a reverse structure along the edge 8, so that the along edge 8 is attached to the upper end surface of the tempered glass layer 1.
[0034] Specifically, the design of the along edge 8 can provide more comprehensive protection for the upper corners of the tempered glass layer 1. The along edge 8 is higher and is attached to the upper end surface of the tempered glass layer 1 in a reverse structure. When subjected to external force impact from the upper end, the along edge 8 can first contact and disperse the impact force. In addition, the design of the along edge 8 can wrap the corners of the tempered glass layer 1, which can more effectively prevent the corners from directly contacting external objects, thereby reducing the risk of corner breakage and collapse.
[0035] In some embodiments, the side end of the protective frame 6 has a plurality of arc-shaped protrusions 9, and the plurality of arc-shaped protrusions 9 are uniformly distributed along the edge of the protective frame 6.
[0036] The curved surface structure of the arc-shaped protrusion 9 can be extruded and deformed when subjected to side impact. By converting external impact energy into material deformation energy, energy absorption is achieved, and the risk of local damage is reduced, thereby further improving the effect of shock absorption and buffering.
[0037] Further, the arc-shaped protrusion 9 has an inner recess 10; the existence of the inner recess 10 makes the local structure of the arc-shaped protrusion 9 weak, becomes the starting point of deformation, compared with the complete solid structure, is more prone to bending or distortion deformation. When the impact energy is transmitted to the arc-shaped protrusion 9, the inner recess 10 will first deform, drive the whole arc-shaped protrusion 9 to further deform, thereby expanding the deformation range and increasing the total amount of energy absorption.
[0038] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims to which they relate.
