It has penetrated into many aspects of our daily lives, bringing great convenience to our daily lives. And with the improvement of living requirements, the demand for explosion-proof glass is getting higher and higher. At present, most glass structures are single-layer structures. Although glass has a certain degree of protection against impact, it is still easy to shatter glass if the impact force is too large. The excellent properties of glass make it widely used in the cover structure of smart devices, such as mobile phones, tablets, home appliances, and car computers. These electronic devices often collide during use and are easily broken when they encounter impact.

A double-layer glass combination is used to form a sandwich structure, and a non-Newtonian fluid is filled in the sandwich structure. When the glass is subjected to impact force, due to the viscoelasticity of the non-Newtonian fluid, the impact force exerted on the glass can be diffused around the non-Newtonian fluid, thereby buffering the impact force exerted on the glass, enhancing the impact resistance of the glass, improving the strength and explosion-proof capability of the glass, and ensuring the safety of the glass during use.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] As described in the background technology, most of the current glass structures are single-layer structures. Although the glass has a certain degree of protection against impact force, it is still easy to shatter the glass if the impact force is too strong. Applying a layer of explosion-proof ink can prevent fragments from flying when the glass breaks and improve the safety of the glass back cover, but it cannot resist the breakage caused by the impact force of the glass.

[0025] In order to solve this technical problem, the utility model provides an explosion-proof glass and a cover plate using the glass, which is applied to the field of mobile phone glass cover plates.

[0026] Specifically, please refer to Figure 1-2 The explosion-proof glass specifically includes a first glass 1 and a second glass 2, wherein a sandwich structure is formed between the first glass 1 and the second glass 2, and the sandwich structure is filled with a non-Newtonian fluid 3.

[0027] The explosion-proof glass provided by the utility model adopts a double-layer glass combination to form a sandwich structure, and a non-Newtonian fluid 3 is filled in the sandwich structure. When the glass is subjected to impact force, the non-Newtonian fluid 3 has viscoelasticity, so the impact force exerted on the glass can be diffused around the non-Newtonian fluid 3, thereby buffering the impact force exerted on the glass, enhancing the impact resistance of the glass, improving the strength and explosion-proof ability of the glass, ensuring the safety of the glass during use, and being suitable for glass cover plates of electronic equipment.

[0028] In order to achieve the above-mentioned purpose, the utility model also provides a cover plate, which is applied to a display cover plate or a rear cover plate of an electronic device, and the cover plate includes the above-mentioned explosion-proof glass, and a sealing layer 4 is provided between the first glass 1 and the second glass 2, and the sealing layer 4 wraps the non-Newtonian fluid 3.

[0029] The cover plate provided by the utility model applies explosion-proof glass to the cover plate of the electronic device, which can improve the impact resistance of the electronic device and solve the problem of screen breakage caused by external force during the use of the electronic device. The first glass 1 and the second glass 2 are tightly connected together by black UV glue, which can have a sealing effect and prevent the non-Newtonian fluid 3 from flowing out. At the same time, the black UV glue can also have a shading effect, reducing the process of coating the shading layer on the subsequent cover plate, thereby improving production efficiency and reducing manufacturing costs.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] Example 1

[0034] Please refer to Figure 1-2, provides an explosion-proof glass, which includes a first glass 1 and a second glass 2, the first glass 1 and the second glass 2 are of equal size and are stacked, a sandwich structure is formed between the first glass 1 and the second glass 2, and the sandwich structure is filled with a non-Newtonian fluid 3, and the non-Newtonian fluid 3 is evenly and equally laid between the first glass 1 and the second glass 2. Since the non-Newtonian fluid 3 has viscoelasticity, the impact force exerted on the glass can be diffused around the non-Newtonian fluid 3, thereby buffering the impact force exerted on the glass, enhancing the impact resistance of the glass, improving the strength and explosion-proof ability of the glass, and ensuring the safety of the glass during use. The glass is suitable for glass cover plates of electronic devices, and in order not to affect the transparent characteristics of the glass, the non-Newtonian fluid 3 is transparent.

[0035] The explosion-proof glass can be used as a cover for electronic devices such as mobile phones, tablets, electronic watches, and car display screens. Specifically, it can be used as a display cover, and of course it can also be used as a back cover for electronic devices such as mobile phones. It can improve the impact resistance of electronic devices and solve the problem of broken screens caused by external forces during the use of electronic devices, thereby increasing the service life of electronic devices.

[0036] At the same time, in order to prevent the non-Newtonian fluid 3 from leaking from the sides of the first glass 1 and the second glass 2, a sealing layer 4 is arranged between the first glass 1 and the second glass 2. The sealing layer 4 is arranged along the outer edge of the non-Newtonian fluid 3, so that the sealing layer 4 wraps the non-Newtonian fluid 3. The sealing layer 4 uses an adhesive layer to tightly bond the first glass 1 and the second glass 2 together. The adhesive layer can use glass glue or UV glue. In this example, UV glue is selected, and UV glue is applied on the surface of one of the glasses, and then a layer of non-Newtonian fluid 3 is evenly spread on the surface of the glass. Then, the two glasses are stacked together, and the UV glue is irradiated by an ultraviolet lamp to cure the UV glue to obtain a sealing layer 4.

[0037] Example 2

[0038] The explosion-proof glass provided in Example 1 is further optimized, specifically, as follows: Figure 1-2 As shown, the surfaces of the first glass 1 and the second glass 2 that are close to each other are both provided with an anti-slip layer 5, and the extension trajectory of the anti-slip layer 5 is consistent with the extension trajectory of the sealing layer 4, so that the anti-slip layer 5 and the sealing layer 4 are arranged correspondingly. The arrangement of the anti-slip layer 5 can improve the connection strength between the first glass 1 and the second glass 2, and the anti-slip layer 5 is concave in the corresponding surface of the first glass 1 or the second glass 2, so that the anti-slip layer 5 and the surface of the first glass 1 or the second glass 2 form a step structure, and when applying UV glue, the UV glue can be prevented from entering the area filled with the non-Newtonian fluid 3. Specifically, the anti-slip layer 5 is an etching layer. After the white glass tempering treatment of the first glass 1 and the second glass 2, a layer of etching cream is evenly applied to the area of ​​the anti-slip layer 5. After a period of time, the etching cream is cleaned and removed, and then an etching layer is formed on the surface of the glass.

[0039] Example 3

[0040] The explosion-proof glass provided in Example 2 is further optimized, specifically, as follows: Figure 3 As shown, when the above-mentioned explosion-proof glass is used as the display cover plate 6, the cover plate 6 includes a visible area 7 and an invisible area 8. In assembly, the visible area 7 is set corresponding to the display inner screen for operating or viewing the display content, and the invisible area 8 is bonded to the glue frame for fixing the cover plate 6. In order to prevent light leakage, a light-shielding layer is generally set around the display cover plate 6. The light-shielding layer can be made of light-shielding ink or a light-shielding film. No matter which light-shielding method is used, additional operation and processing of the cover plate 6 is required. For this reason, in this embodiment, the sealing layer 4 is set in the invisible area 8 of the cover plate 6, and the inner circle trajectory of the sealing layer 4 is consistent with the intersection trajectory of the invisible area 8 and the visible area 7. At the same time, the sealing layer 4 is black UV glue, so that the sealing layer 4 has a light-shielding effect, which reduces the light-shielding processing process of the original cover plate 6, simplifies the operation process, and improves production efficiency. For electronic devices with cameras such as mobile phones, a camera hole 9 is also set at the invisible area 8. In order to achieve a shooting effect, the sealing layer 4 should also avoid the camera hole 9.

[0041] The explosion-proof glass and the cover plate using the glass provided by the utility model have the following working principles: a double-layer glass combination is used to form a sandwich structure, and a non-Newtonian fluid 3 is filled in the sandwich structure. When the glass is subjected to impact force, the non-Newtonian fluid 3 has viscoelasticity, so the impact force exerted on the glass can be diffused around the non-Newtonian fluid 3, thereby buffering the impact force exerted on the glass, enhancing the impact resistance of the glass, improving the strength and explosion-proof ability of the glass, and ensuring the safety of the glass during use. The utility model is suitable for glass cover plates of electronic devices, which can improve the impact resistance of electronic devices and solve the problem of broken screens caused by external forces exerted on electronic devices during use. The first glass 1 and the second glass 2 are tightly connected together using black UV glue, which can have a sealing effect and prevent the non-Newtonian fluid 3 from flowing out. At the same time, the black UV glue can also have a shading effect, reducing the process of coating the shading layer on the subsequent cover plate, thereby improving production efficiency and reducing manufacturing costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms.
