Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a tempered film with a buffer border arranged by using a filling and spacing structure. Background Art

[0002] In the current era of highly popular electronic devices, tempered films, as important accessories for protecting the screens of electronic devices, are playing an increasingly prominent role. However, there are still some problems with the common tempered films on the market during use. When the tempered film is attached or after being used for a period of time, white edge structures often appear at its edges. To solve this problem, some tempered films will be provided with colored silk-screen borders at the edges to block the white edges, and some tempered films will be provided with border structures for blocking. The traditional border structures are generally glue-dotted borders or metal borders. Among them, if the glue-dotted border is directly set on the surface of the tempered film, it is easy to fall off after being used for a period of time. Therefore, the glue-dotted border is generally set at the bottom layer of the tempered film, but setting the glue-dotted border at the bottom layer cannot protect the edges of the tempered film. When there is a bump or other situation, the edges of the tempered film are extremely easy to crack. Although the metal border can provide good protection for the edges of the tempered film, when there is a bump, the metal border will apply force to the tempered film, which will also cause the edges of the tempered film to break. In view of this, it is necessary to propose an improved technical solution to solve the above problems. Content of the Utility Model

[0003] The utility model aims to provide a technical solution that can solve the above problems to overcome the above situations.

[0004] A tempered film with a buffer border arranged by using a filling and spacing structure includes a tempered film main body, a metal protection border arranged at the edge of the tempered film main body, and a buffer isolation border arranged between the tempered film main body and the metal protection border to play an isolation and bonding role. Among them, a step groove is opened at the edge position of the tempered film main body, the cross-section of the metal protection border is a right-angle structure, and the metal protection border is in clearance fit with the step groove. The buffer isolation border is filled in the gap between the metal protection border and the step groove, so that the upper end of the metal protection border is flush with the upper end of the tempered film main body, and the lower end of the metal protection border is flush with the lower end of the tempered film main body.

[0005] Preferably, an upper extension part covering the wall surface of the step groove extends from the inner side of the buffer isolation border, and a lower extension part covering the side part of the tempered film main body extends from the outer side of the buffer isolation border. The metal protection border includes a top protection part and a side protection part that are vertically matched. The top protection part is bonded and supported on the buffer isolation border and is bonded and matched with the upper extension part, and the side protection part is bonded outside the lower extension part.

[0006] Preferably, chamfered portions are provided at the opposite edge positions of the top protection portion and the tempered film body. The upper extension portion has a lower filling section and an upper filling section. Among them, the upper filling section is made of a colored material, and the upper filling section is adhesively combined with the lower filling section, and the upper filling section fills the chamfers provided on the top protection portion and the tempered film body.

[0007] Preferably, the thickness of the buffer isolation frame is 0.5mm - 0.12mm.

[0008] Preferably, a first adhesive layer extending to the lower end of the metal protection frame is attached to the lower end of the tempered film body. A layer of explosion-proof film layer is attached to the lower end of the first adhesive layer. A layer of second adhesive layer is attached to the lower end of the explosion-proof film layer. A release film layer is attached to the lower end of the second adhesive layer.

[0009] Preferably, an anti-fingerprint oil film is coated on the upper end of the tempered film body.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] Through the combination of the buffer isolation frame and the metal protection frame, when the tempered film is bumped, the external force can be effectively isolated and buffered, reducing the local force on the tempered film body, and greatly improving the anti-damage ability of the tempered film. The high hardness of the metal protection frame can withstand a large external force impact, providing a reliable first line of defense for the tempered film body; the metal protection frame is designed with a right-angled cross-section structure, which cooperates with the CNC machining step structure at the edge of the tempered film body, and can more comprehensively protect the edge of the tempered film body to prevent the edge from being damaged in various situations; in addition, after precise dimension calculation, when the metal protection frame is fixed on the tempered film body through the buffer isolation frame, the flush fit of the two can be achieved. This not only makes the appearance of the tempered film more beautiful, but also avoids affecting the use experience due to the unevenness of the frame, such as not generating a scraping feeling when operating the mobile phone. At the same time, the flush fit also helps to improve the overall stability and durability of the tempered film.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , in the embodiments of the present utility model, a tempered film with a buffer frame set by using a filling and spacing structure is proposed, including a tempered film main body 10, a metal protection frame 20 arranged on the edge of the tempered film main body 10, and a buffer isolation frame 30 arranged between the tempered film main body 10 and the metal protection frame 20 to play an isolation and bonding role. Among them, a step groove 11 is opened at the edge position of the tempered film main body 10, the cross-section of the metal protection frame 20 is a right-angle structure, the metal protection frame 20 is in clearance fit with the step groove 11, and the buffer isolation frame 30 is filled in the gap between the metal protection frame 20 and the step groove 11, so that the upper end of the metal protection frame 20 is flush with the upper end of the tempered film main body 10, and the lower end of the metal protection frame 20 is flush with the lower end of the tempered film main body 10.

[0021] When the edge of the tempered film is bumped, the outermost metal protection frame 20 first comes into contact with the external force. Due to the high hardness of the metal protection frame 20, it can resist the impact of the external force to a certain extent. The acting force generated by the bump is then transmitted to the buffer isolation frame 30 between the metal protection frame 20 and the tempered film body 10. On the one hand, the buffer isolation frame 30 firmly fixes the metal protection frame 20 on the tempered film body 10 through the bonding effect. On the other hand, by using its own elasticity and isolation characteristics, it buffers and isolates the transmitted acting force. In this way, the local force acting on the tempered film body 10 is reduced to the greatest extent, thus protecting the tempered film body 10 from damage.

[0022] Therefore, through the combination of the buffer isolation frame 30 and the metal protection frame 20, when the tempered film is bumped, it can effectively isolate and buffer the external force, reduce the local force on the tempered film body 10, and greatly improve the anti-damage ability of the tempered film. The high hardness of the metal protection frame 20 can withstand a large external force impact and provides a reliable first line of defense for the tempered film body 10.

[0023] The metal protection frame 20 is designed with a right-angled cross-section structure, which cooperates with the CNC machining step structure on the edge of the tempered film body 10, and can more comprehensively protect the edge of the tempered film body 10 to prevent the edge from being damaged in various situations.

[0024] In addition, after precise dimension calculation, when the metal protection frame 20 is fixed on the tempered film body 10 through the buffer isolation frame 30, a flush fit between the two can be achieved. This not only makes the appearance of the tempered film more beautiful, but also avoids affecting the use experience due to the unevenness of the frame, such as not generating a scraping feeling when operating the mobile phone. At the same time, the flush fit also helps to improve the overall stability and durability of the tempered film.

[0025] Please refer to Figure 2, on the basis of the above technical solution, it is further proposed that an upper extension portion 31 covering the wall surface of the step groove 11 extends inside the buffer isolation frame 30, and a lower extension portion 32 covering the side portion of the tempered film body 10 extends outside the buffer isolation frame 30. The metal protection frame 20 includes a top protection portion 21 and a side protection portion 22 that are vertically fitted. The top protection portion 21 is adhesively supported on the buffer isolation frame 30 and adhesively cooperates with the upper extension portion 31. The side protection portion 22 is adhesively bonded outside the lower extension portion 32. When the tempered film with the buffer isolation frame 30 of this special structure is bumped at the edge, the external force first acts on the metal protection frame 20. The top protection portion 21 and the side protection portion 22 of the metal protection frame 20 are vertically fitted, and the force received by the top protection portion 21 will be transmitted to the buffer isolation frame 30 that is adhesively supported therewith. The upper extension portion 31 of the buffer isolation frame 30 covers the wall surface of the step groove 11, and the top protection portion 21 is adhesively cooperated with the upper extension portion 31, so that the force is further dispersed to the upper extension portion 31. At the same time, the lower extension portion 32 of the buffer isolation frame 30 covers the side portion of the tempered film body 10, and the side protection portion 22 of the metal protection frame 20 is adhesively bonded outside the lower extension portion 32. In this way, when the side protection portion 22 is subjected to an external force, the force will also be transmitted to the buffer isolation frame 30 through the lower extension portion 32. The buffer isolation frame 30 uses its own elasticity and isolation characteristics to isolate and buffer the forces from different parts of the metal protection frame 20, thereby minimizing the local force on the tempered film body 10 to the greatest extent.

[0026] Please refer to Figure 2, on the basis of the above technical solution, it is further proposed that chamfered portions are provided at the edge positions where the top protection portion 21 and the tempered film main body 10 face each other. The upper extension portion 31 has a lower filling section 33 and an upper filling section 34. Among them, the upper filling section 34 is made of a colored material. The upper filling section 34 is adhesively fitted with the lower filling section 33, and the upper filling section 34 fills the chamfers provided on the top protection portion 21 and the tempered film main body 10; this structural setting makes the edges of the metal protection frame 20 and the tempered film main body 10 not too sharp, preventing the situation of scratching fingers during use. And in order to achieve this structure, the buffer isolation frame 30 is divided into two parts, that is, the upper part of the upper extension portion 31 of the buffer isolation frame 30 is separated as the upper filling section 34. During the production process, by reasonably controlling the amount of glue applied to the inner side of the metal protection frame 20, and then bonding the metal protection frame 20 on the step groove 11 of the tempered film main body 10. After the glue solidifies, the buffer isolation frame 30 without the upper filling section 34 is formed. On this basis, further glue application is carried out so that the second glue application can fill the chamfers at the edge positions where the top protection portion 21 and the tempered film main body 10 face each other. And by adopting this operation of secondary glue application, the degree of secondary glue application is uniform, and different color glues can be used according to the requirements of the product, playing a role in beautifying and decorating the surface of the produced tempered film.

[0027] Please refer to Figure 2 , on the basis of the above technical solution, it is further proposed that the thickness of the buffer isolation frame 30 is 0.5 mm - 0.12 mm; when the thickness of the buffer isolation frame 30 is within this range, it can provide appropriate buffering when subjected to external impact, neither being unable to effectively absorb and disperse the impact force due to being too thin, nor affecting the overall fitting degree and use feel of the tempered film due to being too thick; therefore, a thickness of 0.5 mm - 0.12 mm can, while ensuring the buffering effect, well isolate the knocking force transmitted by the metal protection frame 20, minimizing the local force on the tempered film main body 10, thereby effectively protecting the tempered film from being easily damaged when subjected to accidental collisions.

[0028] Please refer to Figures 2-3, on the basis of the above technical solution, it is further proposed that a first adhesive layer 12 extending to the lower end of the metal protection frame 20 is attached to the lower end of the tempered film body 10. A lower end of the first adhesive layer 12 is attached with an explosion-proof film layer 13. A lower end of the explosion-proof film layer 13 is attached with a second adhesive layer 14. A lower end of the second adhesive layer 14 is attached with a release film layer 15; in addition, an anti-fingerprint oil film (not shown in the figure) is coated on the upper end of the tempered film body 10. The first adhesive layer 12 closely adheres the tempered film body 10 and the explosion-proof film layer 13 together, and at the same time extends to the lower end of the metal protection frame 20 to ensure the stability of the overall structure; the explosion-proof film layer 13 obtains a firm attachment through the first adhesive layer 12. When subjected to an external impact, it can further absorb and disperse the impact force to prevent the fragments from splashing after the tempered film breaks; the second adhesive layer 14 connects the explosion-proof film layer 13 and the release film layer 15. The release film layer 15 plays a protective role before use and can be peeled off during use, so that the second adhesive layer 14 can paste the entire tempered film on the device screen; when the tempered film is subjected to an external impact, first, a part of the impact force is borne by the metal protection frame 20, and then the buffer isolation frame 30 performs buffering; if the impact force is large, there may be a risk of rupture of the tempered film body 10. At this time, the explosion-proof film layer 13 can effectively prevent the fragments from splashing and protect the device and the user's safety; the anti-fingerprint oil film is coated on the upper end of the tempered film body 10. In daily use, when a finger touches the tempered film, the anti-fingerprint oil film can reduce the residue of fingerprints and oils, keep the screen clean and clear, and at the same time make the touch operation smoother.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
