Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, and in particular to a film applicator that uses a flip cover to automatically remove the upper protective film. Background Technology

[0002] With the numerous benefits that touchscreen technology has brought to ease of operation, device design and functional expansion, as well as user interaction and experience, many electronic products such as mobile phones and tablets are equipped with touchscreens that cover almost the entire surface. However, because the screen needs to be touched constantly during use, and because it covers almost the entire surface of the electronic product, it is easily scratched, bumped, and damaged, and is not drop-resistant and cannot withstand large impacts. Therefore, a protective film is often applied to the surface before use to provide a certain degree of protection.

[0003] Because there are many types of screen protectors, and because screen protectors themselves can be damaged after impacts and knocks, most screen protectors are purchased and used by users themselves. During use, to accurately apply the screen protector to the screen, most screen protectors come with an applicator. For example, a more traditional method involves a protective film on the top surface of the screen protector for positioning with the applicator. A tear-off strip is attached to the release liner of the screen protector, allowing the applicator to first position the screen protector against the screen, and then pulling the tear-off strip to peel off the release liner and apply the screen protector. This method achieves precise positioning of the screen protector and a dust-free application process.

[0004] Existing methods for fixing the upper protective film to the film applicator primarily involve clips or adhesive bonding. The upper protective film is typically made of silicone or similar adhesive materials, allowing it to adhere tightly to the tempered glass film surface. This ensures the film remains firmly attached when not in use, without crumbling, and prevents damage or residue when removed. However, due to the high adhesion of silicone to tempered glass, improper handling during the application and removal of the applicator, such as failing to separate the upper protective film from the applicator beforehand, can easily cause the applicator to exert excessive force on the film, leading to tearing or even breakage of the tempered glass film due to the sudden, excessive force. Therefore, an improved technical solution is needed to address these problems. 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] A screen protector applicator that automatically detaches the upper protective film using a flip cover includes a base and a flip cover that are rotatably connected to each other to achieve flip-to-close. A screen positioning structure is provided on the base, and an upper protective film for applying the protective film is provided on the flip cover. One end of the upper protective film is extended to provide a snap-fit ​​section with a snap-fit ​​hole. The flip cover is provided with a snap-fit ​​post that is interference-fitted with the snap-fit ​​hole. A slit is provided on the side of the snap-fit ​​post to position and snap the snap-fit ​​section. After the snap-fit ​​hole and the snap-fit ​​post are interference-fitted, the upper snap-fit ​​section is positioned on the snap-fit ​​post by the mating of the snap-fit ​​section and the slit. The slit is located on the side of the snap-fit ​​post opposite to one end of the flip cover that is rotatably connected to the base.

[0007] The other end of the upper cover is extended with a tongue section, and the end of the flip cover away from the rotating connecting base is provided with a draw slot, and the tongue section is movably connected to the draw slot.

[0008] Preferably, the snap-fit ​​post has a square cross-section, with a notch on one side of the snap-fit ​​post, and the side of the snap-fit ​​post with the notch has a straight surface and arc surfaces corresponding to both sides of the straight surface.

[0009] Preferably, there are two snap-fit ​​holes and two snap-fit ​​posts, and the two snap-fit ​​holes and two snap-fit ​​posts are designed to prevent fooling.

[0010] Preferably, a support bracket is provided at the end of the flip cover away from the rotating connection base. The support bracket is a long strip structure and the spacing between it and the flip cover is matched so that a slot is formed between the support bracket and the flip cover.

[0011] Preferably, when the flip cover is closed on the base, the flip cover and the base at one end of the support bracket form a clearance opening that connects the flip cover and the base.

[0012] Preferably, the screen positioning structure is a groove structure formed on the base to abut the periphery of the screen to be applied, and the base has a pick-and-place opening to facilitate the placement of the screen to be applied onto the screen positioning structure.

[0013] Preferably, the flip cover is provided with a pressing cotton strip for pressing down the upper protective piece, and a fastener is provided on the end of the flip cover away from the rotating connecting base. The base is provided with a fastening groove that engages with the fastener, so that the flip cover and the base are fixed together by the fastener and the fastening groove.

[0014] Preferably, the pressure strip has a T-shaped structure, a transverse strip structure, or a longitudinal strip structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By utilizing the flip-up action of the cover and base, combined with the special connection method between the upper protective film and the flip-up cover, the protective film and the screen to be covered are precisely positioned and matched. After the film is applied, the upper protective film can be automatically detached by flipping up the cover. This avoids damage to the protective film caused by improper manual separation of the upper protective film and the film applicator, such as tearing or breaking. This greatly improves the success rate and quality of the film application.

[0017] The upper protective film is securely and reliably positioned on the flip cover through the engagement of the snap-fit ​​holes and snap-fit ​​posts, and the tongue segment and pull-out slot, ensuring the stability of all components before screen protector application. The removal process after screen protector application is automatic, achieved simply by opening the flip cover normally. Opening the cover allows the tongue segment to detach automatically, and the cut edge pushes out the snap-fit ​​post, allowing it to be gradually pulled out from the snap-fit ​​post. The entire process requires no additional complex steps or tools, and the handling of the upper protective film does not affect the adhesion between the screen protector and the screen to be covered.

[0018] This screen protector applicator pre-attaches the protective film and top cover to the flip cover before shipping. Once the flip cover and base are closed, they act as a protective shell for the screen protector. During the application process, users do not need to perform any pre-application steps. Simply open the flip cover, position the screen with the screen protector to be applied on the base, close the flip cover, and peel off the release liner to attach the protective film to the screen. After application, no further steps are required. Simply open the flip cover and peel off the top cover, which automatically detaches from the flip cover, from the protective film. The entire process is simple and requires no additional complicated steps or tools. Users do not need to learn how to use the applicator and it is easy to master.

[0033] 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.

[0034] Please see Figure 1-10In this embodiment of the utility model, a screen protector applicator that automatically detaches the upper protective film using a flip cover includes a base 10 and a flip cover 20 that are rotatably connected to each other to achieve flip-to-close. A screen positioning structure 11 is provided on the base 10, and an upper protective film 30 for attaching the protective film is provided on the flip cover 20. One end of the upper protective film 30 is extended to provide a snap-fit ​​section 31, and a snap-fit ​​hole 32 is provided on the snap-fit ​​section 31. A snap-fit ​​post 21 is provided on the flip cover 20 to be interference-fitted with the snap-fit ​​hole 32. A cutout 22 is provided on the side of the snap-fit ​​post 21 to position and snap-fit ​​the snap-fit ​​section 31. After the snap-fit ​​hole 32 and the snap-fit ​​post 21 are interference-fitted, the upper snap-fit ​​section 31 is positioned on the snap-fit ​​post 21 by the docking of the snap-fit ​​section 31 and the cutout 22. The position of the cutout 22 on the side of the snap-fit ​​post 21 is opposite to one end of the flip cover 20 that is rotatably connected to the base 10.

[0035] The other end of the upper cover 30 is extended with a tongue section 33, and the end of the flip cover 20 away from the rotating connecting base 10 is provided with a draw slot 23, and the tongue section 33 is movably connected to the draw slot 23.

[0036] In the above technical solution, the screen protector applicator uses a base 10 and a flip cover 20 that flip and fit together. The screen to be protected is positioned on the screen positioning structure 11, while the protective film is positioned on the flip cover 20 by the upper protective tab 30. When the flip cover 20 is closed, the protective film and the screen to be protected will be located between the flip cover 20 and the base 10. Since the positions of the upper protective tab 30 and the screen to be protected positioning structure remain unchanged, by aligning the positions of the upper protective tab 30 and the screen to be protected positioning structure, the protective film and the screen to be protected can be precisely matched after the flip cover 20 and the base 10 are closed. If necessary, the release liner 50 can be used to peel the release liner off the protective film from the screen to be protected and the screen to be protected, thereby achieving a dust-free application effect. Based on this, a new technical solution is adopted for the matching method between the upper protective tab 30 and the flip cover 20, that is, based on the structure of the screen protector applicator with flip-fitting mechanism...

[0037] The upper protective sheet 30 is securely fixed to the flip cover 20 by using a snap-fit ​​hole 32 and a snap-fit ​​post 21 at one end, and by utilizing the engagement of the notch 22 and the snap-fit ​​hole 32. The upper protective sheet 30 is made of silicone sheet material, possessing both hardness and flexibility. It deforms to pass through the snap-fit ​​post 21 and snap into the notch 22, ensuring one end of the upper protective sheet 30 is firmly and reliably fixed to the flip cover 20. The other end of the upper protective sheet 30 is engaged with the flip cover 20 by a tongue segment 33 and a drawer slot 23. After the upper protective sheet 30 engages with the snap-fit ​​post 21 through the snap-fit ​​hole 32, the tongue segment 33 is then inserted into the drawer slot 23, securing the upper protective sheet 30 firmly and reliably to the flip cover 20.

[0038] This structure, besides enabling the positioning and fixing of the upper protective film 30 and the flip cover 20, cleverly utilizes the flipping action of the flip cover 20 to achieve the purpose of detaching the upper protective film 30 from the flip cover 20. That is, when the flip cover 20 and the base 10 are closed, and the protective film is accurately applied to the screen to be covered, the upper protective film 30 is attached to the protective film, and the protective film is attached to the screen to be covered, thus positioning the screen to be covered on the base 10. When the application is complete, the screen to be covered needs to be removed. When the screen is being opened, the flip cover 20 needs to be opened first. During this process, since the tongue segment 33 and the slot 23 are engaged in a movable docking manner, and the upper protective sheet 30 itself has a certain degree of flexibility, and the upper protective sheet 30 is attached to the protective film, the opening action will gradually move the flip cover away from the screen to be covered. At this time, the tongue segment 33 will deform due to the constraint of the protective film and disengage from the slot 23. That is, the opening operation of the flip cover 20 will enable the tongue segment 33 to automatically disengage from the flip cover 20.

[0039] Furthermore, as the flipping action progresses, the locking post 21 will rotate synchronously with the flip cover 20. Since the cutout 22 is located on the side of the locking post 21 opposite to one end of the flip cover 20 rotating connection base 10, and the upper protective sheet 30 is also constrained by the protective film and needs to gradually detach from the flip cover 20, as... Figure 5-6 As shown, as the upper protective sheet 30 gradually detaches from the flip cover 20 and the locking post 21 gradually flips, the edge of the cut 22 will squeeze out the locking segment 31 that is inserted therein. After the locking segment 31 is squeezed out of the cut 22, it will no longer be subject to the locking force, and thus it can be gradually pulled out from the locking post 21. After the flipping action is completed, the upper protective sheet 30 will also completely detach from the flip cover 20 and be attached to the protective film. At this time, you can first remove the screen with the film and then peel off the upper protective sheet 30, or directly peel off the upper protective sheet 30 and then remove the screen with the film to be applied.

[0040] Please see Figure 9-10In this embodiment of the present invention, the snap-fit ​​post 21 has a square cross-section, with a notch 22 on one side of the snap-fit ​​post 21. The side of the snap-fit ​​post 21 with the notch 22 has a flat surface 211 and arc surfaces 212 corresponding to both sides of the flat surface 211. The square cross-section design of the snap-fit ​​post 21, compared to other shapes such as circles, provides clearer positioning and limiting for the snap-fit ​​section 31 of the upper cover 30. When the snap-fit ​​hole 32 and the snap-fit ​​post 21 are press-fitted, the square edges can better hold the snap-fit ​​section 31, making it less prone to circumferential rotation or displacement, thus ensuring a more stable and precise initial fixation of the upper cover 30 on the flip cover 20. The notch 22 is located on one side of the snap-fit ​​post 21, and this side has a flat surface 211 and arc surfaces 212 corresponding to both sides of the flat surface 211. The presence of the flat surface 211 makes the position and boundary of the cut 22 clearer and more regular. When the snap-fit ​​segment 31 snaps into the cut 22, the flat surface 211 can form a stable contact with the snap-fit ​​segment 31, preventing it from easily slipping out of the cut 22. The curved surfaces 212 on both sides play a transitional role. On the one hand, during the process of the snap-fit ​​segment 31 passing through the snap-fit ​​post 21 and snapping into the cut 22, the curved surface 212 can guide the snap-fit ​​segment 31 to enter the correct position more smoothly and reduce jamming. On the other hand, when the upper protective piece 30 is subsequently detached from the snap-fit ​​post 21, the curved surface 212 can make the snap-fit ​​segment 31 complete the detachment action more smoothly during the process of being squeezed out by the edge of the cut 22, avoiding damage to the snap-fit ​​segment 31 or the snap-fit ​​post 21 itself due to its overly sharp shape.

[0041] Please see Figure 5 and Figure 9 In this embodiment of the utility model, it is further proposed that there are two snap-fit ​​holes 32 and two snap-fit ​​posts 21, and the two snap-fit ​​holes 32 and two snap-fit ​​posts 21 are designed to prevent mistakes. This not only improves the stability and reliability of the connection between the upper protective sheet 30 and the flip cover 20, but also ensures the accuracy of operation through the mistake-proof mechanism. This has a positive effect on the good performance of the overall function of the film applicator and the convenience of use.

[0042] Please see Figure 1 , Figure 5 and Figure 9 In this embodiment of the present invention, a support bracket 24 is further provided on the end of the flip cover 20 away from the rotating connecting base 10. The support bracket 24 is a long strip structure and is spaced to match the flip cover 20. It is similar to a beam structure and is set on the flip cover 20, so that a draw slot 23 is formed between the support bracket 24 and the flip cover 20. This structure is simple in design and allows the tongue segment 33 to have a certain degree of flexibility after being inserted into the draw slot 23, so that the tongue segment 33 can be easily pulled out and detached during the subsequent flipping action.

[0043] Please see Figure 1-5In this embodiment of the present invention, when the flip cover 20 is closed on the base 10, a clearance opening 25 is formed at one end of the support bracket 24 of the flip cover 20 and the base 10, which communicates between the flip cover 20 and the base 10. The clearance opening 25 is positioned so that the tear strip 50 connecting the release film can extend beyond the film applicator along the clearance opening 25, thereby allowing the release film to be torn off after the flip cover 20 is closed. The screen positioning structure 11 is a groove structure formed on the base 10 to abut against the periphery of the screen to be applied, and the base 10 is provided with a pick-and-place opening 12 to facilitate the placement and removal of the screen to be applied onto the screen positioning structure 11. A pressing cotton strip 40 for pressing down the upper protective piece 30 is provided on the flip cover 20, and a fastener 26 is provided on the end of the flip cover 20 away from the rotating connecting base 10. A fastening groove 13 is provided on the base 10 to engage with the fastener 26, so that the flip cover 20 and the base 10 are fixed by the fastener 26 and the fastening groove 13 after they are closed. Through the cooperation of the pressure strip 40 and the snap-fit ​​parts and snap-fit ​​slots, the flip cover 20, after being closed, can have a certain constraint between the flip cover 20 and the base 10, thereby driving the pressure strip 40 to press down the protective film on the upper protective film 30. This allows the protective film to be pressed and adhered to the screen to be covered by the pressure strip 40. The pressure strip 40 can be configured as a T-shaped structure, with its front end horizontally pressing down on the front end of the protective film, allowing the front end of the protective film to adhere to the screen first. Then, the middle vertical section gradually guides the protective film to expel air from front to back, ensuring that no air bubbles are generated between the protective film and the screen after application. Furthermore, in addition to being T-shaped, the pressure strip 40 can also... Figure 3-4 As shown, the pressure strip 40 can also be a horizontal strip structure, a vertical strip structure, or other structures. Its main purpose is to guide the protective film and the screen to be covered to adhere to the screen without air bubbles and to achieve a faster bonding operation.

[0044] 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.
