Description

Technical Field

[0001] This utility model relates to the field of tempered glass film technology, and in particular to a tempered glass film that enables privacy protection for the front-facing camera lens. Background Technology

[0002] With the widespread use of smartphones, tablets, and other mobile devices, users' demand for screen protection and privacy protection is increasing. Tempered glass screen protectors, as a mainstream screen protection accessory, have become an essential product for mobile devices due to their high strength, scratch resistance, and good light transmission. The core functions of existing tempered glass screen protectors mainly focus on basic protection such as screen drop prevention, scratch resistance, and fingerprint prevention. Their structure typically includes the tempered glass body and a release liner for adhesion. The tempered glass body has a fixing hole corresponding to the front-facing camera of the mobile device to prevent obstruction of the lens and ensure normal operation of functions such as shooting and facial recognition. However, in real-world usage scenarios, the privacy issues of front-facing cameras are becoming increasingly prominent. For example, when users use mobile devices in public places, the front-facing camera may be compromised by people around them through malicious filming or screen peeping, who may steal their facial features, environmental information, and other private information. Furthermore, the front-facing camera on some mobile devices may unintentionally activate while running background programs, further increasing the risk of privacy leaks. Currently, there is no integrated solution on the market to address the need for privacy protection of front-facing cameras: traditional tempered glass screen protectors only have a fixed through-hole and do not have privacy protection; separate lens cover stickers can achieve this, but they require additional application and removal, are cumbersome, and are easily lost. Repeated application can also affect the adhesion and may damage the tempered glass or the device surface; while protective cases with mechanical blocking structures are complex and bulky, increasing the difficulty of carrying the device, and are separate components from the tempered glass, failing to provide integrated protection.

[0003] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A tempered glass screen protector for front-facing camera privacy protection includes a tempered glass screen protector body, a release film, and a privacy shield. The tempered glass screen protector body is attached to the release film. The tempered glass screen protector body has a movable window with a flat structure. The privacy shield is movably connected to the movable window and has a damping fit with the movable window. A blocking ring is also formed around the inner side of the movable window, and the privacy shield is restricted within the movable window by the blocking ring.

[0006] Preferably, a PET anti-reflective film is adhered to the back of the tempered glass film body, and an OCA adhesive layer is adhered to the back of the PET anti-reflective film. The tempered glass film body is attached to the release film through the OCA adhesive layer. The privacy screen is restricted to the movable window by the PET anti-reflective film and the blocking ring.

[0007] Preferably, an annular groove is CNC-cut within the active window, and the active window forms a blocking ring through the annular groove.

[0008] Preferably, the privacy screen includes a damped cylindrical movable part connected within the movable window and a protrusion axially formed on the cylindrical movable part, the protrusion extending along the blocking ring to above the surface of the tempered glass body.

[0009] Preferably, the privacy screen is made of black, opaque material.

[0010] Preferably, a dotted adhesive ring is coated around the barrier ring on the tempered glass film body, and the privacy screen protector engages with the movable window through the dotted adhesive ring.

[0011] Preferably, the edge of the tempered glass film body is also provided with a silkscreened border.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By integrating a privacy shutter into the tempered glass screen protector, it achieves dual functions of screen protection and lens privacy, meeting users' integrated usage needs. Compared to a separate lens cover, the privacy shutter is movably connected to the tempered glass screen protector, eliminating the need for additional pasting or removal. This makes it convenient to operate and less prone to loss, avoiding damage to the tempered glass screen protector or terminal surface caused by repeated pasting. Compared to protective cases with mechanical blocking structures, this tempered glass screen protector has a simpler structure and smaller size, does not increase the difficulty of carrying the terminal, and has a higher fit to the terminal. In addition, the damping action between the privacy shutter and the movable window, as well as the limiting effect of the blocking ring, ensures that the shutter slides smoothly and will not fall off. This avoids problems such as jamming or self-slipping, and keeps the shutter stably in the privacy or usage position, improving the stability and reliability of use.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0014] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a partial cross-sectional structural diagram of the present invention; Figure 3 This is an exploded structural diagram of the present invention; Figure 4 This is a utility model Figure 3 A schematic diagram of the structure at point A in the middle.

[0016] The reference numerals and names in the figure are as follows: Tempered glass film body 10, movable window 11, blocking ring 12, annular groove 13, adhesive ring 14, silk screen border 15, release film 20, privacy screen protector 30, cylindrical movable part 31, protrusion 32, PET anti-reflective film 40, OCA adhesive layer 50. Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see Figure 1-4 In this embodiment of the present invention, a tempered glass screen protector that enables privacy protection for a front-facing camera includes a tempered glass screen protector body 10, a release film 20, and a privacy shield 30. The tempered glass screen protector body 10 is attached to the release film 20. The tempered glass screen protector body 10 has an active window 11 with a flat structure. The privacy shield 30 is movably connected to the active window 11 and has a damping fit with the active window 11. A blocking ring 12 is also formed around the inner side of the active window 11, and the privacy shield 30 is restricted within the active window 11 by the blocking ring 12.

[0019] In use, the release film 20 is peeled off from the tempered glass screen protector body 10, allowing the adhesive side of the tempered glass screen protector body 10 to adhere to the surface of the mobile terminal screen. The flat movable window 11 on the tempered glass screen protector body 10 will precisely correspond to the position of the terminal's front-facing camera. When the user does not need to use the front-facing camera and requires privacy protection, the privacy shield 30 inside the movable window 11 can be directly pushed. Because the privacy shield 30 and the movable window 11 have a damping fit, the user can easily control the shield to slide to a position that completely covers the front-facing camera. At the same time, the surrounding blocking ring 12 on the inner side of the movable window 11 can prevent the privacy shield 30 from falling off the window, ensuring a stable shielding state and achieving lens privacy protection. When the user needs to use the front-facing camera for shooting, facial recognition, or other operations, simply push the privacy shield 30 in the opposite direction to slide it away from the front-facing camera area, allowing the camera to work normally. The entire process does not require disassembling the tempered glass screen protector or any additional accessories. The privacy shield 30 can be flexibly switched between privacy protection and usage modes by sliding it.

[0020] Therefore, by integrating the privacy shutter 30 onto the tempered glass screen protector body 10, the dual functions of screen protection and lens privacy are achieved, meeting the user's integrated usage needs. Compared to a separate lens cover, the privacy shutter 30 is movably connected to the tempered glass screen protector body 10, requiring no additional pasting or disassembly, making it convenient to operate and less likely to be lost, avoiding damage to the tempered glass screen protector or terminal surface caused by repeated pasting. Moreover, compared to protective cases with mechanical blocking structures, this tempered glass screen protector has a simple structure and small size, does not increase the difficulty of carrying the terminal, and has a higher degree of fit with the terminal. In addition, the damping cooperation between the privacy shutter 30 and the movable window 11, as well as the limiting effect of the blocking ring 12, ensures that the shutter slides smoothly and will not fall off, avoiding the problems of jamming or self-sliding, and allowing the shutter to be stably maintained in the privacy or usage position, improving the stability and reliability of use.

[0021] Please see Figure 2-3 Based on the above technical solutions, it is further proposed that a PET anti-reflective film 40 is adhered to the back of the tempered glass screen protector body 10. The PET anti-reflective film 40, through a special optical structure or coating design, can effectively reduce the reflectivity of ambient light on the film surface, reduce the interference of reflection on the screen display content, and allow users to clearly see the text and images on the screen even under strong light, avoiding visual fatigue caused by reflection and significantly improving the screen viewing experience under different lighting scenarios. An OCA adhesive layer 50 is adhered to the back of the PET anti-reflective film 40. The OCA adhesive layer 50 has the characteristics of high transparency, high adhesion and no air bubbles after adhesion. The tempered glass screen protector body 10 is attached to the release film 20 through the OCA adhesive layer 50. The privacy shutter 30 is restricted in the movable window 11 by the PET anti-reflective film 40 and the blocking ring 12, which can more reliably prevent the privacy shutter 30 from falling off from the window.

[0022] Please see Figure 2and Figure 4 Based on the above technical solution, it is further proposed that an annular groove 13 be cut in the movable window 11 by CNC, and the movable window 11 forms a blocking ring 12 through the annular groove 13. The CNC cutting process has the advantages of high precision and high consistency. Compared with the traditional forming method, it can make the size, depth and circumferential flatness of the annular groove 13 more accurate, thereby making the fit gap between the formed blocking ring 12 and the anti-peeping shield 30 more uniform, effectively avoiding the problem of the shield getting stuck or loose due to the forming error of the blocking ring 12.

[0023] A dotted adhesive ring 14 is coated around the barrier ring 12 on the tempered glass screen protector body 10. The privacy screen protector 30 is damped by the dotted adhesive ring 14 and the movable window 11. The coating process of the dotted adhesive ring 14 is simple and controllable. The thickness and adhesion of the adhesive layer can be adjusted according to actual needs, and it can flexibly adapt to privacy screen protectors 30 made of different materials.

[0024] Please see Figure 2 Based on the above technical solution, it is further proposed that the privacy shield 30 is made of black opaque material, which can block external vision from stealing privacy through the front lens; the privacy shield 30 includes a cylindrical movable part 31 damped and connected in the movable window 11 and a protrusion 32 axially formed on the cylindrical movable part 31, the protrusion 32 protruding along the blocking ring 12 to the surface of the tempered film body 10; the cylindrical movable part 31 can form a stable damping cooperation with the movable window 11 to ensure that it is not easy to deviate during the sliding process and cause jamming, further ensuring a smooth sliding feel and stable stopping state, while the setting of the protrusion 32 can provide a clear force point for user operation, and the shield can be easily pushed to switch states without the aid of tools. An adhesive ring 14 is coated around the barrier ring 12 on the tempered glass screen protector body 10. The privacy screen protector 30 is damped by the adhesive ring 14 and the movable window 11. The adhesive ring 14 can strengthen the protection of the barrier ring 12 and also provide a certain degree of buffering and isolation for the privacy screen protector 30, thereby improving the damping cooperation between the privacy screen protector 30 and the movable window 11.

[0025] Please see Figure 1 Based on the above technical solution, it is further proposed that the edge of the tempered glass film body 10 is also provided with a silk screen frame 15, which can cover the tiny gaps or attachment deviations that may exist between the tempered glass film and the edge of the screen.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
