Description

Technical Field

[0001] The utility model relates to a technical field, in particular to a high-strength mobile phone glass cover. Background Art

[0002] Mobile phone cover glass refers to the glass layer on the front of a phone that protects the screen and touch sensor. It not only protects the internal display panel and touch sensor from external impact, scratches, and abrasion, but also provides excellent optical transparency to ensure a clear display. Mobile phone cover glass is typically specially treated to ensure high toughness, scratch resistance, light transmittance, and a pleasant feel for daily use. The structural design and manufacturing process technology for mobile phone cover glass has achieved considerable development, primarily involving multi-level optimization from material selection to processing to ensure that strength and durability are enhanced while also balancing aesthetics, touch sensitivity, and light transmittance. Specifically, the structural design of mobile phone cover glass emphasizes thinness, beautiful curved surfaces, composite layers, and multi-layered protection. These layers are based on high-strength chemically strengthened glass and nano-coating technologies. The manufacturing process utilizes cutting, polishing, chemical strengthening, coating, and curved molding to ensure the cover glass has excellent impact resistance, scratch resistance, touch sensitivity, and visual quality. Technically, these features are being developed towards higher durability, stain resistance, flexibility, and low reflectivity to meet the diverse application needs of the future.

[0003] To improve their strength, existing mobile phone glass cover plates are typically made of high-strength, high-toughness, and high-transparency materials. These materials, such as chemically strengthened aluminosilicate glass, high-hardness chemically strengthened glass, sapphire glass, and ceramic glass composite materials, are used to strengthen the structural strength of the mobile phone cover plates. Alternatively, chemical treatments are used to immerse the glass in molten potassium salts for ion exchange, where larger potassium ions replace sodium ions on the glass surface, creating compressive stress on the surface and improving impact resistance. However, these strengthening methods primarily target the structural strengthening of the glass layer of the mobile phone glass cover plate, resulting in insufficient wear resistance, scratch resistance, and support for the existing mobile phone glass cover plates. Utility Model Content

[0004] Based on this, it is necessary to provide a high-strength mobile phone glass cover to address the technical problems of the existing mobile phone glass cover having insufficient wear resistance, scratch resistance and support.

That is, the protective glass layer is attached to the surface of the high-toughness glass layer facing the anti-scratch coating, and the anti-scratch coating is evenly coated on the surface of the protective glass layer facing away from the high-toughness glass layer.

[0013] In one embodiment, the protective glass layer is formed by attaching chemically strengthened glass to the surface of the high-toughness glass layer.

[0014] In one embodiment, the above-mentioned plastic composite layer includes a microporous support layer and a microgrid support layer. The microporous support layer is attached to the surface of the high-toughness glass layer facing away from the anti-scratch coating, and the microgrid support layer is attached to the surface of the microporous support layer facing away from the high-toughness glass layer. Thus, the microporous support layer cooperates with the microgrid support layer to provide stable support for the strengthened coating and the glass composite layer.

[0015] In one embodiment, the plastic composite layer further includes a nano coating, and the nano coating is coated on a surface of the microgrid support layer facing away from the microporous support layer.

[0016] In one embodiment, the nano coating is made of one of carbon nanotubes and nano oxides.

[0017] In one embodiment, the frame includes a first reinforcement portion and a second reinforcement portion, and the first reinforcement portion and the second reinforcement portion are respectively installed on two sides of the frame to strengthen the structural strength of the two side walls of the frame.

[0018] In one embodiment, the first reinforcement portion is provided with a plurality of first reinforcement blocks, which are arranged along the length extension direction of the corresponding side wall on the inner surface of the frame side wall to enhance the bending resistance of the corresponding side wall of the frame.

[0019] In one embodiment, the second reinforcement portion is provided with a plurality of second reinforcement blocks, which are arranged on the inner surface of the frame side wall along the length extension direction of the corresponding side wall to enhance the bending resistance of the other side wall of the frame.

[0020] The above-mentioned high-strength mobile phone glass cover plate is formed by sequentially stacking and connecting a strengthening coating, a glass composite layer, and a support layer to form the overall structure of the cover plate body.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.

[0031] See also Figures 1 to 4The present invention discloses a high-strength mobile phone glass cover, which includes a cover body 100 and a frame 200. The frame 200 corresponds to the edge of one side surface of the cover body 100. Based on this, the cover body 100 is arranged on one side of the frame 200 and snap-fitted to form the entire mobile phone glass cover. Specifically, the cover body 100 includes a strengthening coating 110, a glass composite layer 120, and a support layer 130. The strengthening coating 110 is arranged on one side surface of the glass composite layer 120, and the support layer 130 is arranged on the other side surface of the glass composite layer 120 opposite to the strengthening coating 110. Thus, the strengthening coating 110, the glass composite layer 120, and the support layer 130 are sequentially stacked and connected to form the overall structure of the cover body 100. Among them, the strengthening coating 110 is set as a scratch-resistant coating, and the scratch-resistant coating is evenly coated on the corresponding side surface of the glass composite layer 120, so as to increase the hardness and wear resistance of the surface of the glass composite layer 120, reduce the generation of scratches, and keep the surface smooth. At the same time, to a certain extent, the external sharp objects of the wall directly contact the glass composite layer 120 and cause damage to the glass composite layer 120; the glass composite layer 120 includes a high-toughness glass layer 121, which is arranged between the scratch-resistant coating and the supporting layer 130. The high-toughness glass layer 121 has good impact resistance, crack resistance and overall durability, and can better To withstand external physical impact, when the high-toughness glass layer 121 is subjected to external force, the high-toughness glass layer 121 can absorb and disperse the impact energy through its stress distribution structure, reduce local stress concentration, and thus effectively reduce the risk of its cracking; the support layer 130 is configured as a plastic composite layer, which is attached to the surface of the glass composite layer 120 facing away from the strengthening coating 110. The plastic composite layer can provide the cover body 100 with stronger toughness and impact resistance. When used as the bottom support structure, it can improve the impact resistance of the overall structure of the mobile phone glass cover and provide a flat and flexible support surface for the glass composite layer 120. Based on the composite cover structure formed by the strengthening coating 110, the glass composite layer 120 and the support layer 130, combined with the frame 200, it can meet the high-strength application requirements of the mobile phone glass cover. When this high-strength mobile phone glass cover is applied to mobile phone products, it can effectively enhance the durability of the mobile phone products and extend their service life, thereby reducing the frequency of repairs and replacements of mobile phone products and improving the user experience.

[0032] Furthermore, the anti-scratch coating uses one of a silicon-based coating and a titanium nitride coating to impart a higher hardness to the glass composite layer 120 and enhance the wear resistance of the surface of the cover plate body 100. Both the silicon-based coating and the titanium nitride coating can increase the hardness and wear resistance of the surface of the glass composite layer 120, thereby reducing the occurrence of scratches, thereby maintaining the smoothness of the surface of the glass composite layer 120 and reducing direct damage to the glass composite layer 120 by external sharp objects.

[0033] Furthermore, the high-toughness glass layer 121 can be made of one of tempered glass, laminated glass, aluminosilicate glass, and borosilicate glass. Among them, tempered glass has higher strength and impact resistance than ordinary glass. When it breaks, it will shatter into granules and will not form sharp fragments, reducing the risk of injury. Laminated glass is made by adding a high-toughness film such as PVB or SGP between multiple layers of glass. It can still remain bonded after breaking, and the fragments are not easy to fall off, preventing injury. The sandwich structure can effectively absorb impact force and reduce crack propagation. Aluminosilicate glass has excellent scratch resistance and thermal stability, while borosilicate glass has extremely high heat resistance and chemical stability. Based on the above material properties, the high-toughness glass layer 121 can select and prepare high-toughness glass with corresponding characteristics according to actual application requirements to correspondingly improve the strength of the mobile phone glass cover.

[0034] Furthermore, the glass composite layer 120 includes a protective glass layer 122, which is disposed between the high-toughness glass layer 121 and the anti-scratch coating. Specifically, the protective glass layer 122 is attached to the side of the high-toughness glass layer 121 facing the anti-scratch coating, and the anti-scratch coating is evenly coated on the side of the protective glass layer 122 facing away from the high-toughness glass layer 121. Specifically, the protective glass layer 122 is made of chemically strengthened glass attached to the surface of the high-toughness glass layer 121. Chemically strengthened glass uses a chemical ion exchange process to form a high-strength compressive stress layer on one side of the glass surface, significantly improving the glass's toughness. Consequently, the chemically strengthened glass can provide high strength to the glass composite layer 120 while maintaining a relatively thin thickness, thereby achieving a lightweight design for the glass composite layer 120.

[0035] Furthermore, the plastic composite layer includes a microporous support layer 131 and a microcellular support layer 132. The microporous support layer 131 is applied to the side of the high-toughness glass layer 121 facing away from the anti-scratch coating, while the microcellular support layer 132 is applied to the side of the microporous support layer 131 facing away from the high-toughness glass layer 121. Thus, the microporous support layer 131 and the microcellular support layer 132 provide stable support for the strengthening coating 110 and the glass composite layer 120. The microporous support layer 131 utilizes a microporous structure to reduce material weight. Furthermore, when subjected to impact, the porous structure can counteract stresses, reducing the risk of crack propagation in the glass composite layer 120. In one embodiment, the plastic composite layer also includes a nanocoating 133. The nanocoating 133 is applied to the side of the microcellular support layer 132 facing away from the microporous support layer 131, forming a thin layer of nanoparticle material. Its densely packed structure enhances the hardness and crack resistance of the plastic composite layer, while the microcellular support layer 132 improves the adhesion of the nanocoating 133. In this embodiment, the nano coating 133 is made of one of nano carbon tubes and nano oxides.

[0036] Furthermore, the frame 200 includes a first reinforcement portion 210 and a second reinforcement portion 220, each mounted on either side of the frame 200 to strengthen the structural strength of the two side walls of the frame 200. Specifically, the first reinforcement portion 210 includes a plurality of first reinforcement blocks 211, which are arranged along the length of the corresponding side wall and disposed on the inner surface of the side wall of the frame 200 to strengthen the bending resistance of the corresponding side wall of the frame 200. Correspondingly, the second reinforcement portion 220 includes a plurality of second reinforcement blocks 221, which are arranged along the length of the corresponding side wall and disposed on the inner surface of the side wall of the frame 200 to strengthen the bending resistance of the other side wall of the frame 200.

[0037] In summary, the high-strength mobile phone glass cover disclosed in the present invention is formed by sequentially stacking and connecting a strengthening coating, a glass composite layer, and a support layer to form the overall structure of the cover body. Among them, the strengthening coating is set as an anti-scratch coating, and the anti-scratch coating is evenly coated on the corresponding side surface of the glass composite layer; the glass composite layer includes a high-toughness glass layer; the support layer is set as a plastic composite layer, and the plastic composite layer is attached to the side surface of the glass composite layer facing away from the strengthening coating. Based on the composite cover structure formed by the stacking of the strengthening coating, the glass composite layer, and the support layer, combined with the frame, the high-strength application requirements of the mobile phone glass cover can be achieved. When the high-strength mobile phone glass cover is applied to mobile phone products, it can effectively enhance the durability of the mobile phone products and extend their service life, thereby reducing the frequency of repairs and replacements of mobile phone products, and thus improving user experience.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention.
