Description

Technical Field

[0001] This utility model relates to the field of tempered glass film technology, specifically a tempered glass film structure with curved edges on both sides. Background Technology

[0002] Tempered glass screen protectors are a type of mobile phone screen protector, a high-end new product offering the strongest protection for your screen. They completely cover the original screen, preventing damage and scratches from external forces, and significantly increase impact absorption, exceeding the standard of PET film by 5 times, without affecting the screen's video quality. Tempered glass uses chemical or physical methods to create compressive stress on the glass surface. When the glass is subjected to external force, this surface stress is first offset, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. This results in superior properties such as high hardness, low toughness, good wear resistance, and scratch resistance.

[0003] As described in the published patent CN208414319U, most tempered glass films used for protecting electronic device displays in the prior art have relatively simple structures. Due to the lack of effective treatment around the edges of the tempered glass film, the feel is extremely poor and it is very easy to cause damage. In addition, when it is attached to the display screen, especially when it is attached to some displays with curved edges, it is difficult to make the edges of the tempered glass film fit the display screen effectively and completely.

[0004] In summary, current tempered glass screen protectors have a problem with the grip feel around the edges when in use. Utility Model Content

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

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A tempered glass membrane structure with curved edges on both sides includes:

[0008] Tempered glass screen protector body;

[0009] The number of extended arc edges is one pair, and the pair of extended arc edges are symmetrical and integrally disposed on both sides of the tempered film body;

[0010] Anti-slip grooves, the anti-slip grooves being formed on the extended arc edge; and

[0011] A surrounding strip is disposed at one end of the extended arc edge.

[0012] As a further embodiment of this utility model: the tempered film body includes, from top to bottom, an inductive electroplating layer, a tempered glass layer, a buffer adhesive layer, an optical layer, an antistatic layer, and an adhesive layer.

[0013] As a further embodiment of this utility model: the extended arc edge is curved, and one end of the extended arc edge is set as a rounded corner structure.

[0014] As a further embodiment of this utility model: the anti-slip groove is a concave arc groove, and there are multiple anti-slip grooves, which are equidistantly arranged along the length direction of the extended arc edge.

[0015] As a further embodiment of this utility model: the surrounding strip is adhered to one end of the extended arc edge, one end of the surrounding strip is a pointed tip, and the bottom of the surrounding strip is a downwardly inclined surface.

[0016] As a further embodiment of this utility model, the surrounding strip is made of silicone.

[0017] As a further embodiment of this utility model: an arc-shaped transition portion is provided on the side of the surrounding strip that is in contact with the extended arc edge. The arc-shaped transition portion includes a first arc-shaped portion and a second arc-shaped portion arranged from top to bottom, and the curvature of the second arc-shaped portion is greater than that of the first arc-shaped portion.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The present invention relates to a tempered glass screen protector structure with curved edges on both sides. By setting extended curved edges on both sides of the tempered glass screen protector body, the curvature of the side of the tempered glass screen protector body can be changed. By reducing the span of the step layer at the connection between the extended curved edge and the edge of the mobile phone screen, the extended curved edge can increase the comfort of gripping and reduce the pressure sensation when gripping.

[0020] 2. The tempered glass film structure with curved edges on both sides of this utility model has an anti-slip groove with an inwardly concave arc groove on the extended arc edge. The treated anti-slip groove is smoother, which reduces the discomfort of gripping and increases the anti-slip property. This can prevent the risk of the tempered glass film structure slipping when gripping it.

[0021] 3. The present invention provides a tempered glass screen protector structure with curved edges on both sides. By providing a surrounding strip at one end of the extended curved edge, the gap between the screen and the edge of the mobile phone screen can be further reduced. Combined with the antistatic layer inside the tempered glass screen protector, dust adhesion around the screen is reduced, thus reducing dust accumulation and facilitating dust cleaning. In addition, the surrounding strip on the extended curved edge can also provide edge protection against impact. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-3 This utility model provides a tempered film structure with curved edges on both sides, including a tempered film body 1, an extended curved edge 8, an anti-slip groove 9, and a surrounding strip 10.

[0029] In this embodiment, the tempered glass film body 1 includes, from top to bottom, an inductive electroplating layer 2, a tempered glass layer 3, a buffer adhesive layer 4, an optical layer 5, an antistatic layer 6, and an adhesive layer 7.

[0030] The inductive electroplating layer 2, tempered glass layer 3, buffer adhesive layer 4, optical layer 5, antistatic layer 6, and adhesive layer 7 can be bonded together to ensure the tightness of the layer-to-layer connection. The inductive electroplating layer 2 can be made of TPU material, which can improve the corrosion resistance of the tempered film, as well as improve its hardness, wear resistance, and other functional properties. The buffer adhesive layer 4 is an OCA buffer adhesive, which can improve the shock resistance of the tempered film. The optical layer 5 can use a blue light filter as the optical material, which can achieve the effect of blue light protection for the tempered film. The antistatic layer 6 is an antistatic agent, which can achieve the effect of dust prevention and adhesion. The adhesive layer 7 can be made of AB glue, which can be used in conjunction with the release film. By peeling off the release film on the adhesive layer 7, the tempered film body 1 can be easily glued to the mobile phone screen through the adhesive layer 7.

[0031] In this embodiment of the present invention, there is a pair of extended arc edges 8, and the pair of extended arc edges 8 are symmetrically and integrally disposed on both sides of the tempered film body 1. The extended arc edges 8 are curved, and one end of the extended arc edges 8 is rounded.

[0032] The integrated design of the extended arc edge 8 with the tempered glass screen protector body 1 indicates that they adopt the same structure. By setting the extended arc edge 8 on both sides of the tempered glass screen protector body 1, the curvature of the side of the tempered glass screen protector body 1 can be changed. This curvature can give the side of the tempered glass screen protector body 1 a streamlined effect. By extending the integrated extended arc edge 8 on the tempered glass screen protector body 1 to the side of the phone and covering the phone screen, the span of the step layer at the connection between the extended arc edge 8 and the edge of the phone screen can be reduced, thereby reducing the pressure feeling when the user holds the phone and squeezes the tempered glass screen protector.

[0033] In this embodiment of the utility model, the anti-slip groove 9 is formed on the extended arc edge 8. The anti-slip groove 9 is a concave arc groove. There are multiple anti-slip grooves 9, and the multiple anti-slip grooves 9 are equidistantly arranged along the length direction of the extended arc edge 8.

[0034] The anti-slip groove 9 on the extended arc edge 8 is rounded around to increase the comfort of gripping. The concave design of the anti-slip groove 9 increases the pressure points between the fingers and the extended arc edge 8, thus giving the tempered glass screen protector anti-slip properties and preventing the risk of slipping when gripping the tempered glass screen protector structure.

[0035] In this embodiment of the utility model, an arc-shaped transition portion 12 is provided on the side of the surrounding strip that is in contact with the extended arc edge 8. The arc-shaped transition portion 12 includes a first arc-shaped portion 13 and a second arc-shaped portion 14 arranged from top to bottom. The curvature of the second arc-shaped portion 14 is greater than that of the first arc-shaped portion 13.

[0036] like Figure 3 As shown: An arc-shaped transition portion 12 is provided on the side of the surrounding strip that is in contact with the extended arc edge. By providing the arc-shaped transition portion 12, the fit between the surrounding strip and the extended arc edge is better, the stress effect of the surrounding strip 10 wrapped around the extended arc edge 8 is better, and the overall structural strength of the tempered film of this utility model is enhanced.

[0037] Meanwhile, the curvature of the second arc-shaped portion 14 is greater than that of the first arc-shaped portion 13. On the one hand, this allows the first arc-shaped portion 13 to better fit and transition with the upper end of the extended arc edge 8, so that the transition of the first arc-shaped portion 13 is not too abrupt. On the other hand, since the bottom of the surrounding strip 10 is a downward sloping surface, by increasing the curvature of the second arc-shaped portion 14, the downward sloping surface at the bottom of the surrounding strip 10 can better fit and transition with the lower end of the extended arc edge 8.

[0038] In one embodiment, since the extended arc edge 8 and the tempered film body 1 adopt an integrated structure, that is, the inductive electroplating layer 2, tempered glass layer 3, buffer adhesive layer 4, optical layer 5, antistatic layer 6 and adhesive layer 7 included in the tempered film body 1 can form the extended arc edge 8. The setting of the extended arc edge 8 is simply to change the straight edge of the side of the traditional tempered film into a curved surface. At this time, the extended arc edge 8 is also a transparent structure. Therefore, the anti-slip groove 9 is set on the transparent extended arc edge 8, which has little impact on the display effect of the mobile phone screen.

[0039] In this embodiment of the utility model, the surrounding strip 10 is disposed at one end of the extended arc edge 8, the surrounding strip 10 is bonded to one end of the extended arc edge 8, one end of the surrounding strip 10 is a pointed tip, and the bottom of the surrounding strip 10 is a downwardly inclined surface.

[0040] The shape design of the surround strip 10, combined with the extended curved edge 8, enhances the aesthetics of the lines and increases the tightness of the connection with the phone screen. With the aim of increasing the tightness of the connection, this minimizes the step between the traditional tempered glass screen protector and the side of the phone screen, reducing dust residue. Combined with the antistatic layer 6 set inside the tempered glass screen protector body 1, dust is less likely to adhere to the extended curved edge 8. Since the bottom of the surround strip 10 is a downward sloping surface, this slope makes it difficult for dust to hide and facilitates quick wiping and cleaning.

[0041] Furthermore, since the surrounding strip 10 wraps around the end of the extended arc edge 8, the rounded corner at one end of the extended arc edge 8 increases the bonding area of ​​the surrounding strip 10, which improves the stability of the bonding and fixing. When the extended arc edge 8 is impacted by external force, the surrounding strip 10 can preferentially contact the impacting object by utilizing the buffering characteristics of the flexible material of the surrounding strip 10. The surrounding strip 10 wrapping around the end of the extended arc edge 8 can play a buffering and anti-collision protection role, which can improve the durability of the tempered film structure.

[0042] In one embodiment, since the extended arc edge 8 is designed to be located near the side of the phone screen, and most phone screens are not full-screen (i.e., they cannot achieve true borderless display), there is a black area around the phone screen. The display area of ​​the phone screen is mainly inside the black area. Therefore, the surrounding strip 10 set on the extended arc edge 8 will extend to the black area. The surrounding strip 10 fits tightly against the surface of the black area, which can reduce the connection gap and prevent dust from being hidden. Since the black area does not display images, the opaque surrounding strip 10 will not affect the display effect of the phone screen.

[0043] In this embodiment: the surrounding strip 10 is made of silicone.

[0044] The silicone surround strip 10 includes a flexible silicone sealing material and also has a certain cushioning effect.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
