[0049] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Modes for Carrying Out the Invention

[0050] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] In order to protect the screens of mobile terminals such as mobile phones and tablets and to ensure that the screens are not scratched during use, a screen protector 210 is usually applied to the screen. However, applying a film requires certain skills. To apply the screen protector 210 properly in one go, one often needs to have a lot of experience in applying films. Otherwise, it is difficult to ensure that the screen protector 210 does not form blisters or is applied crookedly. There is even the possibility that the surface of the screen protector 210 is uneven, which requires multiple adjustments and repeated application. This not only easily leads to the entire screen protector 210 being scrapped, but is also time-consuming and labor-intensive. Therefore, it is often necessary to use a film applying device 100 to assist in film application to increase the success rate of film application. However, the inner tray 130 in the film applying device 100, which is used to define the placement position of the mobile terminal and the screen protector 210, is prone to deformation, causing the entire film applying device 100 to be scrapped. As a result, when the user needs to apply the film again, they often need to purchase a new film applying device 100, or a new screen protector 210 to obtain the film applying device 100, which increases the cost of film application for the user.

[0054] In view of this, the present application proposes a film-sticking device 100, which is used to stick a film on the screen of a device 300 to be stuck with a film. The device 300 to be stuck with a film can be a mobile terminal device with a specific shape, such as a mobile phone or a tablet, and the screen protective film 210 used is often a tempered film, and of course it can also be a hydrogel film.

[0055] In an embodiment of the present application, as shown in Figures 1 to 15, the film-sticking device 100 includes an upper cover 110, a base 120 and an inner tray 130. The upper cover 110 and the side of the base 120 are movably connected. The inner tray 130 includes a bottom plate 131 and a limiting frame 132 provided on the bottom plate 131. The limiting frame 132 is enclosed on the bottom plate 131 to form a receiving groove 133, and the inner wall of the limiting frame 132 is provided with a limiting step 134 for installing the screen protective film 210. The opposite sides of the limiting frame 132 are respectively provided with a positioning notch 135 and a pulling notch 136; the inner tray 130 is detachably installed on the side of the base 120 facing the upper cover 110, and the upper cover 110 is used to cover the receiving groove 133.

[0056] Specifically, the upper cover 110 is movably connected to the side of the base 120, that is, the upper cover 110 can be rotatably connected to one side of the base 120, or the upper cover 110 and the base 120 are separately provided. The inner tray 130 is provided on a side of the base 120 facing the upper cover 110, and the opening of the receiving groove 133 of the inner tray 130 is arranged away from the base 120. When the film applying device 100 is opened, the upper cover 110 does not cover the receiving groove 133, so that the device 300 to be film applied is placed in a preset position, so that the screen of the device 300 to be film applied is aligned with the screen protective film 210 (at this time, there is a small gap or contact between the screen and the screen protective film 210); then the upper cover 110 is made to cover the receiving groove 133, and the user presses the base 120 and the upper cover 110 to make the screen and the screen protective film 210 abut, and at the same time tears off the protective layer 214 on the screen protective film 210 by hand-tear tape 215 (the protective layer 214 on the screen protective film 210 can also be torn off by hand-tear tape 215 first, and then presses the base 120 and the upper cover 110 to make the screen and the screen protective film 210 abut), thereby achieving fast and accurate film application. Because the inner tray 130 is easily deformed during use and is therefore a consumable item, it can be detachably mounted on the side of the base 120 facing the upper cover 110, making it easy to replace the inner tray 130. When film application is needed again, the user can simply replace the inner tray 130 without having to replace the entire film application device 100, thereby reducing the user's film application costs.

[0057] 1 to 4 and 7 , the upper cover 110 may be connected to the long side (the side extending in the upward and downward directions) of the base 120 ; and referring to FIG. 8 to 11 , the upper cover 110 may also be connected to the short side (the side at an angle to the long side) of the base 120 .

[0058] According to the needs of different users, each film laminating device 100 may be equipped with only one inner tray 130 or multiple inner trays 130. When a film laminating device 100 is equipped with multiple inner trays 130, that is, in addition to an inner tray 130 fixed to the base 120, the film laminating device 100 also includes at least another inner tray 130, so that the user can replace the inner tray 130 in a timely manner without having to purchase it multiple times. Moreover, the models of the multiple inner trays 130 can be the same, or part of them can be the same and the other part can be different, or they can be arranged differently, so that one film laminating device 100 can meet the film laminating needs of multiple different models or sizes of film laminating equipment 300, further reducing the film laminating cost for users. Referring to Figure 15, multiple inner trays 130 can be stacked to facilitate the storage and packaging of the film laminating device 100 and reduce the space occupied by the film laminating device 100. Assume that the film laminating device 100 includes two inner trays 130, configured as a first inner tray 130a and a second inner tray 130b. The bottom of the second inner tray 130b has a slot for the first inner tray 130a to be inserted into (i.e., the bottom of the limiting frame 132 of the second inner tray 130b is hollow). This allows the first inner tray 130a and the second inner tray 130b to partially overlap in the thickness direction, thereby reducing the total thickness of the multiple inner trays 130 and the overall volume of the film laminating device 100. When the first inner tray 130a and the second inner tray 130b are nested together, the bottom of the second inner tray 130b abuts the limiting step 134 within the first inner tray 130a, so the second inner tray 130b is not completely nested on the first inner tray 130a.

[0059] Since the film-sticking device 100 is often sold as a gift together with the screen protective film 210, the number of inner trays 130 can be the same as the number of screen protective films 210. In one embodiment, the film-sticking device 100 includes at least one screen protective film 210 and at least one inner tray 130, and each screen protective film 210 is installed in a corresponding inner tray 130, thereby reducing the user's process of manually placing the screen protective film 210.

[0060] In this embodiment, the screen protective film 210 includes a film body 211, a first release film 212 and a second release film 213. The first release film 212 and the second release film 213 are respectively adhered to the opposite sides of the film body 211; the opposite ends of the first release film 212 extend outward from the film body 211 to the positioning notch 135 and the pull-out notch 136 respectively, and the second release film 213 includes a protective layer 214 and a hand-tear tape 215. The protective layer 214 is adhered to the surface of the film body 211, and the hand-tear tape 215 is connected to the protective layer 214 adjacent to the positioning notch 135, and extends toward the pull-out notch 136 to the outside of the accommodating groove 133.

[0061] The inner tray 130 includes a bottom plate 131 and a limiting frame 132 provided on the bottom plate 131. The limiting frame 132 is enclosed on the bottom plate 131 to form a receiving groove 133. The receiving groove 133 can accommodate the device 300 to be film-applied and the screen protective film 210, thereby positioning the device 300 to be film-applied and the screen protective film 210. The inner wall of the limiting frame 132 is provided with a limiting step 134 for installing the screen protective film 210, thereby further fixing the screen protective film 210 and reducing the possibility of displacement of the screen protective film 210 during the film-applied process. Along the upper and lower directions of the inner tray 130, the upper limit of the limiting frame 132 is A positioning notch 135 is provided on the side (the upper side of the device 300 to be film-applied), and a pulling notch 136 is provided on the lower side (the lower side of the device 300 to be film-applied). The opposite ends of the first release film 212 extend outward from the film body 211 to the positioning notch 135 and the pulling notch 136 respectively, and the protruding part of the first release film 212 can be adhered to the positioning notch 135 and the pulling notch 136, thereby upper-limiting the screen protective film 210, ensuring the installation stability of the screen protective film 210, and facilitating the sliding of the hand-tear tape 215. After the film is applied, the device 300 to be film-applied is taken out, and the first release film 212 can be directly torn off.

[0062] Among them, the positioning notch 135 can be opened on the entire short side of the accommodating groove 133, or on part of the short side of the accommodating groove 133; the pulling notch 136 can be opened on the entire short side of the accommodating groove 133, or on part of the short side of the accommodating groove 133.

[0063] In one embodiment, the stop step 134 is supported on the edge of the screen protective film 210 and spaced apart from the bottom plate 131. This reduces the possibility of the first release film 212 adhering to the bottom plate 131 during removal after application, which could cause the screen protective film 210 to accidentally lift up.

[0064] 4 to 6 , in one embodiment, the limiting step 134 includes a limiting surface 134a and an abutting surface 134b, which are arranged at an angle. The limiting surface 134a faces the sidewall of the receiving groove 133, while the abutting surface 134b faces the opening of the receiving groove 133, thereby supporting the screen protective film 210. The limiting surface 134a is arranged around the periphery of the screen protective film 210 to limit the installation position of the screen protective film 210, while the abutting surface 134b faces the opening of the receiving groove 133, thereby supporting the screen protective film 210 and ensuring that the screen protective film 210 is spaced apart from the chassis 131.

[0065] Furthermore, a supporting surface 134c is provided above the limiting surface 134a, and the supporting surface 134c faces the opening of the accommodating groove 133 to support the device 300 to be film-applied, and the distance between the supporting surface 134c and the abutting surface 134b is greater than or equal to the thick bottom of the screen protective film 210, so that before the film-applying action is performed, there is no mutual squeezing effect between the screen and the screen protective film 210.

[0066] In one embodiment, the abutting surface 134b is flush with the bottom surface of the positioning notch 135. This ensures the stability of the screen protection film 210. Of course, in other embodiments, the abutting surface 134b may be slightly higher than the bottom surface of the positioning notch 135, or slightly lower than the bottom surface of the positioning notch 135. In one embodiment, the distance between the abutting surface 134b and the bottom surface of the positioning notch 135 is less than the distance between the supporting surface 134c and the abutting surface 134b.

[0067] In order to improve the closing stability of the upper cover 110, in one embodiment, a first magnetic portion 139 is provided on the side of the limiting frame 132 close to the upper cover 110, and a second magnetic portion is provided corresponding to the upper cover 110. When the upper cover 110 covers the accommodating groove 133, the first magnetic portion 139 and the second magnetic portion are magnetically connected.

[0068] When the inner tray 130 is detachably mounted on the base 120, in one embodiment, referring to Figures 1 to 8, the inner tray 130 is snap-fitted to the base 120. That is, a snap-fit ​​structure is provided between the inner tray 130 and the base 120, thereby facilitating the removal and installation of the inner tray 130.

[0069] Furthermore, the chassis 131 is provided with a mounting skirt 131c on the outer side of the limiting frame 132, and the mounting skirt 131c is snap-fitted to the base 120. Specifically, the mounting skirt 131c is provided around the outer periphery of the limiting frame 132. By snapping the mounting skirt 131c to the base 120, the assembly of the inner tray 130 can be facilitated, and the impact of the snap-fitting structure on the structure of the limiting frame 132 can be reduced.

[0070] The snap-fit ​​structure includes a latching protrusion 121 provided on one of the mounting skirt 131c and the base 120, and a latching groove 131a provided on the other. When the mounting skirt 131c is mounted on the base 120, the latching protrusion 121 latches into the latching groove 131a. Of course, in other embodiments, the snap-fit ​​structure can also be configured as two buckles. In other embodiments, the snap-fit ​​structure can be provided between the limiting frame 132 and the base 120.

[0071] To facilitate the processing of the base 120, referring to FIG7 , the base 120 includes a base plate 122 and a clip 123 fixed to the base plate 122. The clip 123 is fixed to the side of the base plate 122 facing the upper cover 110, and the chassis 131 is clipped to the clip 123. Specifically, the base 120 is configured as a plate-like structure, with the clip 123 being clipped to the chassis 131, and the base plate 122 being rotatably connected to the upper cover 110, thereby facilitating the processing of the base 120. The clip 123 is fixed to the base plate 122, for example, by direct bonding, riveting, or by fasteners or connectors. In other embodiments, the clip 123 and the base plate 122 are integrally formed. To facilitate the rotation of the upper cover 110, a connecting plate 112 is bent and connected to one side of the upper cover 110. The other side of the connecting plate 112 is bent and connected to the base plate 122, thereby facilitating the opening and closing of the upper cover 110.

[0072] When the base 120 is engaged with the inner tray 130, in one embodiment, referring to Figures 1 to 8, a first pressing protrusion 111 is provided on the side of the upper cover 110 facing the inner tray 130; a second pressing protrusion 124 is provided on the side of the base 120 facing the inner tray 130, and a through hole 131b is provided on the bottom plate 131, and the second pressing protrusion 124 passes through the through hole 131b and extends into the accommodating groove 133.

[0073] Specifically, the first pressing protrusion 111 is used to press the side of the device 300 facing away from the screen to adhere the screen to the screen protective film 210. The second pressing protrusion 124 is used to press the screen protective film 210 against the screen, thereby bidirectionally pressing the screen and the screen protective film 210 to reduce the generation of bubbles. In this case, the second pressing protrusion 124 is provided on the base 120. The bottom plate 131 is provided with a through hole 131b. The second pressing protrusion 124 passes through the through hole 131b and extends into the receiving groove 133. This allows the second pressing protrusion 124 to not only press the screen protective film 210 against the screen, but also further position the inner tray 130 when it is installed on the base 120.

[0074] The first pressing protrusion 111 and the second pressing protrusion 124 are both configured as flexible components such as cotton strips, cotton blocks, or rubber blocks. This provides a cushion for the adhesion between the screen and the screen protective film 210 while also reducing the possibility of the first pressing protrusion 111 scratching the surface of the device 300 to be applied and the screen protective film 210.
