[0031] Currently, most consumers apply films to mobile devices through ordinary film application methods or semi-simple film applicators. The existing film application devices on the market usually sell the protective film and the film application device as a set. The protective film is fixed to the film application device with double-sided tape. The protective film is prone to positional movement during transportation or operation, resulting in low positioning accuracy or unstable positioning of the protective film, making it easy to apply the protective film crooked during film application, affecting the use of the mobile device. At the same time, the film application operation steps are relatively cumbersome, time-consuming, and inconvenient to disassemble, install, and replace, resulting in a poor product experience for users. To solve the above technical problems, please refer to Figure 1 and Figure 2 , which is an embodiment of a film application device for a mobile device in an embodiment of the present application, including a protective film assembly 1, a box body 2, and a pressing block 3. The protective film assembly 1 is adapted to the mobile device model for fitting with the mobile device. The pressing block 3 is detachably connected to the box body 2, and the protective film assembly 1 is fixed in the box body 2 through the pressing block 3.

[0032] Please continue to refer to Figure 1 and Figure 2Specifically, the box body 2 is provided with a first limiting structure 21 and a second limiting structure 22. The first limiting structure 21 is adapted to the model of the protective film assembly 1, and the second limiting structure 22 is adapted to the model of the mobile device. The protective film assembly 1 is located in the first limiting structure 21 to limit the protective film assembly 1, and the mobile device is located in the second limiting structure 22. When the film is applied, the mobile device is limited to avoid displacement of the mobile device. The area of the first limiting structure 21 is smaller than the area of the second limiting structure 22. The center point of the second limiting structure 22 and the center point of the first limiting structure 21 are both located on the central axis perpendicular to the bottom surface of the box body 2 to ensure that the center point of the protective film assembly 1 and the center point of the mobile device are both located on the central axis perpendicular to the bottom surface of the box body 2, that is, the protective film assembly 1 is aligned with the mobile device, reducing the probability of the protective film assembly 1 being crooked.

[0033] The protective film assembly 1 is provided with a fixing portion 11, and the fixing portion 11 is located between the pressing block 3 and the box body 2 so as to fix the fixing portion 11 to the box body 2 through the pressing block 3. The protective film assembly 1 and the box body 2 are modularized, and the protective film assembly 1 is located in the first limiting structure 21. The fixing portion 11 of the protective film assembly 1 fixed by the pressing block 3 enables the protective film assembly 1 to be stably connected to the box body 2, thereby preventing the protective film assembly 1 from moving during transportation or operation, and improving the positioning accuracy of the protective film assembly 1. Preventing the protective film assembly 1 from moving during transportation or operation improves the positioning accuracy of the protective film assembly 1, and reduces the probability of the protective film assembly 1 being crookedly pasted, thereby ensuring the film pasting effect.

[0034] The protective film assembly 1 includes a film body, an isolation film and an upper protective film. The isolation film and the upper protective film are arranged on both sides of the film body and are bonded to the film body. The isolation film and the upper protective film are used to protect the film body. The upper protective film is located between the film body and the bottom wall of the box body 2. The fixing part 11 is configured on the upper protective film, and the isolation film is away from the bottom wall of the box body 2.

[0035] The protective film assembly 1 and the pressing block 3 are modularized. In actual applications, spare protective film assemblies 1 and pressing blocks 3 are provided in the box body 2 to reduce the failure of the protective film assembly 1 caused by misoperation or to replace the mobile device with a spare. When applying the film, first tear off the isolation film from the film body, place the mobile device in the second limiting structure 22 so that the protective film assembly 1 is aligned with the device, and use the gravity of the mobile device to press on the film body, so that the film body adheres to the mobile device. After the film application is completed, separate the pressing block 3 from the box body 2, take out the mobile device from the second limiting structure 22, and take out the upper protective film and the film body adhered to the mobile device at the same time. Tear off the upper protective film to obtain the mobile device adhered with the film body; place the new protective film assembly 1 in the first limiting structure 21, and fix the fixing part 11 to the box body 2 through the pressing block 3 for the next film application. This makes the box body 2 reusable. This film application operation step is simple and time-consuming, and the disassembly, replacement and installation of the protective film assembly 1 are convenient, which improves the user's satisfaction with the product.

[0036] Both the pressing block 3 and the fixing part 11 are provided with two and correspond one by one. The two fixing parts 11 are respectively arranged at both ends of the protective film assembly 1, and the two pressing blocks 3 are respectively arranged at both ends of the second limiting structure 22, and the two pressing blocks 3 are arranged on the central axis of the protective film assembly 1 in the length direction to fix both ends of the protective film assembly 1. In other embodiments, the two pressing blocks 3 can be arranged on the central axis of the protective film assembly 1 in the width direction to fix both sides of the protective film assembly 1. The first limiting structure 21 limits the protective film assembly 1 in the circumferential direction, and the two pressing blocks 3 cooperate to fix both ends of the protective film assembly 1, further enhancing the positioning accuracy of the protective film assembly 1, thereby improving the film application accuracy.

[0037] Please refer to Figure 1 and Figure 3 , in this embodiment, the first limiting structure 21 is formed by enclosing the bottom surface of the box body 2 and the support strip 211 arranged on the bottom surface of the box body 2. The length direction of the support strip 211 is the same as the long side direction of the box body 2, and the support strip 211 is integrally formed with the box body 2, which enhances the strength of the box body 2 and at the same time enables the volume of the box body 2 to be produced as small as possible, reducing the material cost and transportation cost.

[0038] The second limiting structure 22 is composed of a plurality of limiting plates that resist the peripheral wall of the mobile device. The plurality of limiting plates are all in contact with the peripheral wall of the mobile device. The limiting plates are integrally formed with the box body 2, and the height of the limiting plates is higher than the height of the support strip 211. In order to make the protective film assembly 1 fully contact the mobile device, the pressing block 3 is arranged outside the second limiting structure 22. The second limiting structure 22 is provided with an avoidance groove 221 for avoiding the fixing part 11. The fixing part 11 passes through the avoidance groove 221 and is fixed to the box body 2 so that the protective film assembly 1 can be as close as possible to the bottom wall of the box body 2, and when the mobile device is placed, the mobile device can be fully contacted with the protective film assembly 1.

[0039] Please refer to Figure 1 , the box body 2 is provided with positioning posts 23 corresponding to the fixing part 11, the fixing part 11 is provided with a first through hole 111 for the positioning posts 23 to pass through, the pressing block 3 is provided with a first insertion hole 31 for the positioning posts 23 to pass through, the positioning posts 23 pass through the first through hole 111 and the first insertion hole 31 at the same time, the positioning posts 23 passing through the first through hole 111 position the fixing part 11, and the pressing block 3 and the box body 2 are inserted through the positioning posts 23 and the first insertion hole 31. Further, an insertion part 32 is arranged on the end face of the pressing block 3 facing the box body 2, a second through hole 112 is arranged on the fixing part 11 corresponding to the insertion part 32, the box body 2 is provided with a second insertion hole 24 for the insertion part 32 to pass through, the insertion part 32 passes through the second through hole 112 and the second insertion hole 24 at the same time, and the pressing block 3 and the box body 2 are inserted through the insertion part 32 and the second insertion hole 24. There is damping between the positioning posts 23 and the first insertion hole 31 and between the insertion part 32 and the second insertion hole 24. The pressing block 3 and the box body 2 are inserted in two directions through the positioning posts 23 and the insertion part 32 to enhance the installation stability between the pressing block 3 and the box body 2.

[0040] Please refer to Figure 1 and Figure 2 , one end of the pressing block 3 far from the second limiting structure 22 is provided with a handle 33, the side wall of the box body 2 corresponding to the handle 33 is provided with an opening 28, the handle 33 is located in the opening 28 and protrudes from the box body 2, and the handle 33 increases the contact area between the user and the pressing block 3, facilitating the operation of the pressing block 3, making the operation of detaching the pressing block 3 from the box body 2 more convenient, thereby reducing the replacement difficulty of the protective film assembly 1.

[0041] A notch 27 is arranged on the side wall of the box body 2. The notch 27 corresponds to the limiting plate and is convenient for grasping the mobile device. The notch 27 is obtained by removing a part of the long side wall of the box body 2, and the lowest end of the notch 27 is flush with the upper end face of the support bar 211. The setting of the notch 27 increases the contact area between the hand and the mobile device, increases the friction between the hand and the mobile device, so as to easily take out the mobile device from the second limiting structure 22.

[0042] In order to reduce the probability of bubble generation during the fitting process of the film body and the mobile device, an exhaust member 25 and an installation groove 26 for accommodating the exhaust member 25 are provided at the bottom of the box body 2. The installation groove 26 is located at the central position of the box body 2, and the exhaust members 25 are all located on the central axis of the box body 2. The exhaust member 25 is located in the installation groove 26 and is fixedly connected to the installation groove 26. The exhaust member 25 is preferably made of foam, and the exhaust member 25 is arranged in a strip shape. The length direction of the exhaust member 25 is the same as the length direction of the protective film assembly 1. The length of the exhaust member 25 is greater than or equal to the length of the first limiting structure 21. The distance between the upper end surface of the exhaust member 25 and the bottom of the box body 2 is greater than the distance between the support strip 211 and the bottom of the box body 2. The exhaust member 25 is in interference fit between the mobile device and the bottom of the box body 2. The mobile device is located on the support strip 211, and the mobile device is supported by the support strip 211 so that there is a small gap between the mobile device and the protective film assembly 1. Under the action of the interference fit of the exhaust member 25, the two sides of the mobile device do not completely contact the protective film assembly 1. When applying the film, the mobile device is pressed, and the exhaust member 25 located at the middle position of the film body exerts a force on the film body, so that the exhaust member 25 contacts and presses against the film body, enabling the film body to be first fitted with the mobile device from the middle. The air between the film body corresponding to the exhaust member 25 and the mobile device will be preferentially squeezed out, and the air exhaust starts from the middle and extends to the two side edges of the mobile device, so that the internal gas can be discharged smoothly, reducing the internal pressure accumulation, thereby reducing the probability of bubbles appearing during film application and making the film application completed more quickly.
