Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a tempered film with a lens protection function. Background Art

[0002] Tempered film for mobile phones, also known as tempered glass film, is a high-tech accessory designed specifically for protecting mobile phone screens. It is made of glass material processed by a special process, with extremely high hardness and impact resistance. It is the mainstream choice for protecting mobile phone screens on the market. The main components of tempered film are raw materials such as sodium silicate and calcium magnesium silicate. It is made by high-temperature treatment and rapid cooling quenching. This process forms compressive stress on the surface of the glass, thereby significantly improving its strength and toughness. Through its high strength, high light transmittance and good touch response, it provides a solid line of defense for users' mobile phone screens.

[0003] Existing tempered films are generally produced in a precise way to pre-cut holes at the position corresponding to the front camera, ensuring that the camera lens can be fully exposed after the tempered film is affixed, without affecting the photo or facial recognition functions. This is because the main purpose of the tempered film is protection. Although the tempered film also has excellent light transmittance, its light transmittance and dispersion rate are still different from the lens on the camera lens. Therefore, if the tempered film covers the camera lens, it will affect the imaging effect of the lens.

[0004] However, due to the above reasons, tempered glass cannot protect the camera lens. When the phone falls accidentally, the camera lens has no protective measures, which causes cracks on the lens surface, affecting the imaging effect of the lens. In addition, the camera lens is at risk of being scratched in daily life because there is no protective measures.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0009] As a further solution of the utility model: the upper side surface and the lower side surface of the light-transmitting lens are respectively flush with the upper side surface and the lower side surface of the tempered film body.

[0010] As a further solution of the utility model: the second adhesive layer has a perforation, the perforation is consistent with the position of the camera, and the perforation is larger than the camera lens.

[0011] As a further solution of the utility model: the tempered film body and the upper side of the light-transmitting lens are coated with an anti-fingerprint coating.

[0012] As a further solution of the utility model: the light-transmitting lens can be a low-dispersion lens made of optical glass.

[0013] As a further solution of the utility model: the first adhesive layer is made of OCA adhesive material.

[0014] As a further solution of the utility model: the second adhesive layer is made of AB glue material.

[0015] Compared with the prior art, the beneficial effects of the present technical solution are as follows: while the tempered film body is used to protect the mobile phone screen, the light-transmitting lens can protect the lens on the mobile phone screen, so that the mobile phone screen is more comprehensively protected, and when the mobile phone falls accidentally, the camera lens is prevented from having cracks on the lens surface due to lack of protection measures, thereby affecting the imaging effect of the lens. At the same time, the lens is protected on a daily basis to prevent scratches on the lens, and the light-transmitting lens utilizes high light transmittance and low dispersion rate to protect the lens while avoiding affecting the imaging effect of the lens.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 A tempered film with lens protection function includes a tempered film body 1, a cylindrical countersunk hole 2 consistent with the position of the lens is opened on the tempered film body 1, and a step structure 3 is formed between the upper end surface of the cylindrical countersunk hole 2 and the upper end surface of the tempered film body 1.

[0026] Specifically, a circle of step structure 3 is die-cut on the upper end surface of the cylindrical countersunk hole 2 and the upper end surface of the tempered film body 1 through the CNC process, wherein the area required for the cylindrical countersunk hole 2 needs to be larger than the lens of the front camera, that is, the area of ​​the transparent lens 4 is larger than the camera lens, so that the space above the camera lens is large enough to prevent the tempered film body 1 from affecting the normal use of the camera lens.

[0027] A light-transmitting lens 4 of the same shape is built into the cylindrical countersunk hole 2, so that the light-transmitting lens 4 is arranged in the cylindrical countersunk hole 2, and a first adhesive layer 5 is provided on the contact surface between the light-transmitting lens 4 and the step structure 3, and the light-transmitting lens 4 is bonded to the tempered film body 1 through the first adhesive layer 5, and a second adhesive layer 6 is provided on the lower side of the tempered film body 1 and the light-transmitting lens 4.

[0028] When using the utility model, the surface of the mobile phone screen is first cleaned to ensure that there is no dust or other impurities on the screen surface that affect the film-sticking effect. The utility model is then buckled on the screen, and the cylindrical countersunk hole 2 opened on the tempered film body 1 is aligned with the camera lens, even if the transparent lens 4 built into the cylindrical countersunk hole 2 is located on the camera lens. Then, the lower side of the tempered film body 1 and the transparent lens 4 are bonded to the mobile phone screen through the second adhesive layer 6.

[0029] At the same time, the transparent lens 4 with the same shape built into the cylindrical countersunk hole 2 is adhered to the contact surface of the step structure 3 through the first adhesive layer 5, that is, the transparent lens 4 is bonded to the tempered film body 1. While the tempered film body 1 is used to protect the mobile phone screen, the transparent lens 4 can protect the lens on the mobile phone screen, so that the mobile phone screen can be more comprehensively protected to prevent the camera lens from having cracks on the lens surface due to lack of protection measures when the mobile phone falls accidentally, thereby affecting the imaging effect of the lens. At the same time, the lens can be protected daily to prevent scratches on the lens, and the transparent lens 4 can use its high light transmittance and low dispersion rate to protect the lens while avoiding affecting the imaging effect of the lens.

[0030] Preferably, the light-transmitting lens 4 is placed in the cylindrical countersunk hole 2 through the step structure 3, so that the contact surface between the light-transmitting lens 4 and the cylindrical countersunk hole 2 has a horizontal surface and a vertical surface, thereby achieving the purpose of enhancing the bonding effect.

[0031] Preferably, the first adhesive layer 5 is made of OCA adhesive material.

[0032] OCA glue has the characteristics of high transparency, thin and uniform, excellent optical performance, etc., and ensures the light transmittance while ensuring that the contact surface between the light-transmitting lens 4 and the step structure 3 is firmly bonded.

[0033] In the embodiment of the utility model, the upper side and the lower side of the light-transmitting lens 4 are flush with the upper side and the lower side of the tempered film body 1 respectively.

[0034] Specifically, after the tempered film body 1 is attached to the mobile phone screen, the upper side of the transparent lens 4 is flush with the upper side of the tempered film body 1, which can reduce the uneven feeling when the user's fingers slide over the transparent lens 4 and the tempered film body 1.

[0035] The lower side of the light-transmitting lens 4 is flush with the lower side of the tempered film body 1 , which can avoid the height difference between the light-transmitting lens 4 and the tempered film body 1 during the pasting process, resulting in a cavity and affecting the appearance.

[0036] In the embodiment of the utility model, the second adhesive layer 6 has a perforation 7, the perforation 7 is consistent with the position of the camera, and the perforation 7 is larger than the camera lens.

[0037] A perforation 7 is provided on the second adhesive layer 6 in accordance with the position of the lens, so as to prevent the second adhesive layer 6 from affecting the imaging of the lens and causing a reduction in the imaging quality. At the same time, the perforation 7 can also be set to be larger than the lens to prevent the second adhesive layer 6 from spreading or deforming when it is pressed together, thereby blocking the lens.

[0038] The coating area of ​​the second adhesive layer 6 includes the tempered film body 1 and the lower side of the light-transmitting lens 4, and a perforation 7 is provided at the lower side of the light-transmitting lens 4 to prevent the lens from being blocked, but the lower side of the light-transmitting lens 4 still has the second adhesive layer 6, which can be understood as: the perforation 7 is the inner circle, and the second adhesive layer 6 on the lower side of the light-transmitting lens 4 is the outer circle. Through this design, the light-transmitting lens 4 and the mobile phone screen are also bonded, which can further improve the firmness of the light-transmitting lens 4.

[0039] Preferably, the second adhesive layer 6 is made of AB glue material.

[0040] In the embodiment of the utility model, the upper side surfaces of the tempered film body 1 and the light-transmitting lens 4 are coated with an anti-fingerprint coating 8 .

[0041] During use of the present invention, the anti-fingerprint coating 8 can prevent fingerprints from appearing on the surface of the tempered film body 1 and the transparent lens 4, thereby preventing fingerprints from being left on the transparent lens 4 and affecting the imaging clarity of the lens.

[0042] Preferably, the light-transmitting lens 4 may be a low-dispersion lens made of optical glass.

[0043] The optical glass makes the light-transmitting lens 4 have the characteristics of high light transmittance and low dispersion rate, thereby avoiding affecting the imaging effect of the lens.

[0044] Meanwhile, the light-transmitting lens 4 may also be a calcium fluoride lens made of calcium fluoride material. Calcium fluoride is a colorless and transparent crystal material with very low dispersion and good transmittance, which also meets the requirements for making the light-transmitting lens 4 .

[0045] It is obvious 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 features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
