[0018] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Reference Figure 1-3 This application provides a simple-to-operate packaging body 10, an inner tray 20, and a film application assembly 30. The inner tray 20 is placed in the packaging body 10, and the film application assembly 30 is placed in the inner tray 20. The packaging body 10 includes a base plate 11 and a flip cover 12. The inner tray 20 is attached to the base plate 11. The side of the inner tray 20 facing away from the base plate 11 has a receiving groove 21 for accommodating and positioning electronic products. The flip cover 12 is rotatably connected to one side of the base plate 11 and can be flipped relative to the base plate 11 to close or open the receiving groove 21. The film application assembly 30 is located at the bottom of the receiving groove 21 and includes a positioning film 31, a tempered glass film 32, and a release film 33, which are applied layer by layer. The positioning film 31 is fixed to the frame 22 of the inner tray 20 and faces the bottom wall of the receiving groove 21. The tempered glass film 32 serves as a screen protector for electronic products. One end of the release film 33 is connected to a pull-out component 34. When the electronic product is placed in the receiving slot 21, the pull-out piece 34 is placed between the release film 33 and the screen of the electronic product. At this time, under the action of external force, the pull-out piece 34 can drive the release film 33 to flip outward and separate from the tempered film 32. The side of the tempered film 32 away from the positioning film 31 can automatically be applied to the screen of the electronic product. Finally, the positioning film 31 needs to be peeled off from the side of the tempered film 32 away from the screen to detach it from the tempered film 32, so as to complete the entire film application process of the electronic product.

[0022] Among them, in conjunction with reference Figure 2 and Figure 4 The bottom wall of the receiving groove 21 has a protruding first soft pad 13, which abuts against the side of the positioning diaphragm 31 opposite to the tempered glass diaphragm 32. A second soft pad 14 is provided inside the flip cover 12. When the flip cover 12 closes the electronic product into the receiving groove 21, the second soft pad 14 abuts against the back of the electronic product. Both the first soft pad 13 and the second soft pad 14 deform, providing a clamping force for the adhesion between the film application assembly 30 and the electronic product. During the film application process, the user does not need to apply additional pressure; simply pulling the pull-out component 34 is sufficient to apply the film to the electronic product. It should be noted that the electronic products mentioned here include, but are not limited to, mobile phones, educational devices, and tablets.

[0023] This utility model provides a screen protector applicator 1. Firstly, since the screen protector assembly 30 is located at the bottom of the receiving groove 21, the user only needs to cover the electronic product, with its screen facing the screen protector assembly 30, and then close the flip cover 12. The user can then pull the pull tab 34 to apply the screen protector to the electronic product. Secondly, the bottom wall of the receiving groove 21 and the inner wall of the flip cover 12 are respectively provided with a first soft pad 13 and a second soft pad 14. When the electronic product is placed in the receiving groove 21 and the flip cover 12 is closed, the first soft pad 13 abuts against the side of the screen protector assembly 30 facing away from the electronic product (abutting against the positioning film 31), and the second soft pad 14 abuts against the back of the electronic product. Both the first soft pad 13 and the second soft pad 14 deform, providing a pressing force for the adhesion between the screen protector assembly 30 and the electronic product. This reduces or eliminates the generation of air bubbles during the application process, greatly improving the success rate of screen protector application. The screen protector 1 of this application is easy to operate. Users only need to install the electronic product in the receiving slot 21 with the screen facing the screen protector assembly 30, then close the flip cover 12, and then pull the pull tab 34 to achieve effective screen protector application.

[0024] Preferably, refer to Figure 5 In one embodiment, the inner tray 20 includes four side frames 22 connected vertically end to end. The inner tray 20 has three first positioning structures 23, distributed on at least two different side frames 22, such that the positions of the three first positioning structures 23 are connected by auxiliary lines to form a planar triangle. The edge of the positioning film 31 has three second positioning structures 35. When the film application assembly 30 is placed in the receiving groove 21, the first positioning structures 23 and second positioning structures 35 align and cooperate to achieve three-point positioning. It should be noted that triangles have stability, so three-point positioning greatly improves the assembly stability of the positioning film 31 and the film application assembly 30 relative to the inner tray 20, preventing the film application assembly 30 from shifting left and right during the application process, thereby improving the application effect. Optionally, continue to refer to... Figure 5 In one embodiment, the first positioning structure 23 is a positioning protrusion 231, and the second positioning structure 35 is a positioning hole 351. When the film-applying assembly 30 is placed in the receiving groove 21, the positioning protrusion 231 passes through the positioning hole 351 to fix the positioning film onto the inner tray 20, thereby fixing the film-applying assembly 30 onto the inner tray 20. It should be noted that in other embodiments, the first positioning structure 23 and the second positioning structure 35 can achieve positioning connection by hooking together, adhesive bonding, or other means. Therefore, in this application, the presence or absence of the positioning protrusion 231 and the positioning hole 351 is not limited.

[0025] Preferably, continue to refer to Figure 5In one embodiment, at least two sidewalls 22 are provided with notches 24 extending longitudinally to the opening of the receiving groove 21, and positioning protrusions 231 protrude from the bottom wall of the notches 24. At least two positioning portions 36 extend from the edge of the positioning film 31, and positioning holes 351 are formed in the positioning portions 36. When the film application assembly 30 is placed in the receiving groove 21, the positioning portions 36 are housed within the notches 24. The notches 24 provide a processing area for the positioning protrusions 231, and the positioning portions 36 provide a processing area for the positioning holes 351. Furthermore, the positioning portions 36 are precisely housed within the notches 24, greatly enhancing the overall compactness of the film applicator 1. It should be noted that the presence or absence of the notches 24 and positioning portions is not limited without considering structural compactness.

[0026] Preferably, refer to Figure 5 In one embodiment, the notch 24 includes a first notch 241 and a second notch 242, which are respectively formed on two side frames 22 on opposite sides of the inner support 20. There are three positioning protrusions 231, two of which protrude from the bottom wall of the first notch 241 and are spaced apart along the length of the corresponding side frame 22, and the remaining positioning protrusion protrudes from the bottom wall of the second notch 242. The positioning part 36 includes a first positioning part 361 and a second positioning part 362. When the film application assembly 30 is placed in the receiving groove 21, the first positioning part 361 is housed in the first notch 241, and the second positioning part 362 is housed in the second notch 242. There are three positioning holes 351, two of which are formed in the first positioning part 361 and allow the positioning protrusion 231 to pass through, and the remaining positioning hole 351 is formed in the second positioning part 362 and allows the positioning protrusion 231 to pass through. The above design of the positions of the positioning protrusion 231, notch 24, positioning hole 351, and positioning part 36 forms a stable three-point positioning. It should be noted that in other embodiments, the three-point positioning can also be taken from the positions on the three different side frames 22 of the inner support 20, so the number of notch 24 and positioning part 36 is not limited.

[0027] Optionally, refer to Figure 5 In one embodiment, the first notch 241 and the second notch 242 are disposed opposite to each other along the film application direction and are bonded to... Figure 1The flip cover 12 can close onto the first notch 241 to form a pull-out hole 25, or the flip cover 12 can close onto the second notch 242 to form a pull-out hole 25. The pull-out hole 25 connects to the receiving groove 21, allowing the pull-out component 34 to extend outward for the user to operate and pull. The two notches 24 are arranged opposite each other to form an isosceles triangle, forming a more stable three-point positioning; on the other hand, they are arranged opposite each other along the film application direction, and one of the notches 24 can also form a pull-out hole 25, realizing multiple uses for one slot. It should be noted that in other embodiments, firstly, the two notches 24 can be formed on two adjacent frames on adjacent inner trays 20 to achieve three-point positioning; secondly, the two notches 24 can also be set on two left and right symmetrical frames on the inner tray 20, and the pull-out hole 25 can be set separately. Therefore, in this application, the setting position of the two notches 24 is not limited, as long as they are formed on different frames 22.

[0028] Preferably, combined with Figure 1 and Figure 2 In one embodiment, the film applicator 1 includes a folding plate 15, which is part of the packaging body 10. The opposite sides of the folding plate 15 are connected to the base plate 11 and the flip cover 12, respectively. When the flip cover 12 is closed in the receiving groove 21, the flip cover 12, the folding plate 15, and the base plate 11 are sequentially connected to form a U-shaped clamping groove (not shown). The inner tray 20 is located within the U-shaped clamping groove, and the outer wall surface of the folding plate 15 faces the inner tray 20. Optionally, the folding plate 15 is rotatably connected to one side of the base plate 11; and / or, the flip cover 12 is rotatably connected to the side of the folding plate 15 away from the base plate 11. Here, the folding plate 15 functions as a three-dimensional support, supporting the packaging body 10 to form a three-dimensional folded box state. The flip cover 12 is indirectly rotatably connected to the base plate 11 through the folding plate 15. It should be noted that the presence or absence of the folding plate 15 is not a limitation in this application. For example, in other embodiments, the flip cover 12 can be directly rotatably connected to the base plate 11, so the folding plate 15 does not need to be provided; or the flip cover 12 can also be rotatably connected to the base plate 11 via a spiral ring, so the folding plate 15 does not need to be provided.

[0029] Preferably, refer to Figure 2 In one embodiment, the receiving groove 21 is symmetrical about left and right with respect to the first soft pad 13; the flip cover 12 is symmetrical about left and right with respect to the second soft pad 14. The two soft pads, which are arranged in a supporting manner, can improve the dust removal effect during the film application process through a centrally balanced pressing force, thereby further improving the film application effect. Optionally, the two soft pads can adopt symmetrical geometric shapes, including but not limited to circular, strip, and rectangular shapes. It should be noted that, without considering the balance of the pressing force, the left and right symmetrical arrangement of the two soft pads is not limited in this application.

[0030] Optionally, in one embodiment, the first pad 13 is a porous sponge and is adhered to the bottom wall of the receiving groove 21; the second pad 14 is a porous sponge and is adhered to the inner side wall of the flip cover 12. The porous sponge is easily deformed and recovers its shape, providing a soft touch. It should be noted that in this application, the materials of the two pads are not limited, nor is the method of fixing the two pads limited; at least one pad can be fixed by adhesive bonding.

[0031] Optionally, refer to Figure 3 In one embodiment, the bottom wall of the receiving groove 21 is recessed to form a first limiting groove 26. A portion of the first pad 13 is embedded within the first limiting groove 26, while the other portion extends out of the first limiting groove 26. Similarly, the inner wall of the flip cover 12 is recessed to form a second limiting groove (not shown). A portion of the second pad 14 is embedded within the second limiting groove, while the other portion extends out of the second limiting groove. Both pads are fixed by the limiting grooves, and they do not require additional alignment during processing. It should be noted that the method of fixing the two pads is not limited; at least one pad can be fixed using a limiting groove.

[0032] It should be noted that the two pads can be fixed in the same way or in different ways. The two pads mentioned above can be fixed in the same way, including but not limited to adhesive bonding and positioning grooves. In other embodiments, the two pads can also be fixed using either adhesive bonding or positioning grooves.

[0033] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive.
