Description

Technical Field

[0001] The present application relates to the technical field of film application tools, and more specifically, to a film application tool and a film application kit applicable to multiple types of protective films. Background Art

[0002] In order to protect the screens of terminal devices such as mobile phones and tablets, users generally stick a layer of film on the flat surface of the terminal device (device to be film-applied), so that the touch screen is not easily scratched. During the film application process, in order to pursue the flatness of the lines and avoid generating bubbles, and keep the appearance of the terminal device beautiful, a film applicator is usually used to assist the user in precise positioning and film application, so as to improve the film application effect.

[0003] There are various types of protective films in the existing market, such as soft protective films, hydrogel protective films, and straight-screen tempered glass protective films applicable to curved screen composite materials. The existing soft protective films and hydrogel protective films and other materials are relatively soft, and they are deformed from the extrusion part first and then pressed on the screen during the extrusion process, so that the soft film is gradually pasted on the screen from front to back. During the process of gradually squeezing and attaching the protective film, the gas is completely discharged in one direction, so it is not easy to form film application bubbles. However, for the tempered glass protective film, which is a hard film, during the film application process, when pressing from front to back, the relatively hard tempered glass protective film is likely to fall off as a whole, so that the rear end of the protective film will come into contact with the screen in advance, thus trapping the gas between the protective film and the screen, and the gas cannot be completely discharged to form bubbles. Therefore, the existing film applicator has a poor effect during the process of applying a hard film, resulting in a limited variety of protective films applicable to the film applicator.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] The purpose of the present application is to provide a film application tool and a film application kit applicable to multiple types of protective films, which solve the problem that the existing film applicator has a poor effect during the process of applying a hard film, resulting in a limited variety of protective films applicable to the film applicator.

[0006] To achieve the above purpose, the technical solution adopted by the present application is:

[0007] On the one hand, the present application provides a film application tool applicable to multiple types of protective films, including:

[0008] A housing, within which a receiving cavity is provided for receiving and positioning a mobile terminal to be film-applied;

[0009] A film sheet limiting part, which is arranged on the housing and is used for connecting the protective film to position and spacedly arrange the protective film on one side of the screen of the mobile terminal;

[0010] The spring piece is detachably connected to the housing and is located at the end of the film pressing direction, and lifts up the end of the protective film.

[0011] When the protective film is pressed to the end, the elastic piece is deformed by force and gives way, so that the end of the protective film escapes from the elastic piece and is attached to the mobile terminal.

[0012] Optionally, the spring piece includes: a spring plate body, which is detachably connected to the housing;

[0013] A protruding sheet body, which is arranged on the spring sheet body and has a front end facing the film pressing direction protruding from the spring sheet body;

[0014] The width of the protruding sheet body in the width direction is smaller than the width of the elastic sheet body in the width direction.

[0015] Optionally, the protruding sheet gradually becomes thinner along a direction close to the front end in the film pressing direction.

[0016] Optionally, two protruding sheets are provided, and the two protruding sheets are arranged on the spring plate body at intervals in the width direction.

[0017] Optionally, a disassembly hole is provided on the housing;

[0018] One side of the spring plate body is provided with an inserting boss, which is embedded in the disassembly hole so that the spring piece can be detachably connected to the shell.

[0019] Optionally, an elastic raising portion is provided on the shell, and the elastic raising portion is located at the front end in the film pressing direction;

[0020] One end of the elastic lifting part is connected to the shell, and the other end is suspended and movable to form a movable end. The movable end of the elastic lifting part extends toward one side of the accommodating cavity, can move downward when squeezed, and rebound upward when not compressed.

[0021] Optionally, the diaphragm limiting portion includes: a first hook and a second hook, and the first hook and the second hook are respectively arranged at two ends of the shell in the length direction;

[0022] The first hook is located at a side of the movable end away from the center of the accommodating inner cavity;

[0023] The first hook is used to connect one end of the protective film in the length direction, and the second hook is used to connect the other end of the protective film in the length direction.

[0024] Optionally, the film sticking tool further comprises a film pressing component, which is movably arranged on the housing, and the protective film is attached to the mobile terminal by being pressed by the film pressing component which moves along the film sticking pressing direction;

[0025] The film pressing assembly includes: a roller frame, which is slidably connected to the shell;

[0026] A rolling roller is rotatably arranged on a roller frame.

[0027] Optionally, a flip cover is further arranged on the housing, and one end of the flip cover is rotatably connected to the housing.

[0028] On the other hand, the present application also provides a film application kit, which includes a film application tool applicable to multiple types of protective films and a protective film as described above;

[0029] The protective film includes: a film application layer, a positioning release layer, and a tearing release layer.

[0030] The beneficial effects of a film application tool applicable to multiple types of protective films provided by the present application are at least as follows: when applying a hard protective film, the mobile terminal to be film-applied is accommodated and limited in the accommodation inner cavity of the housing, with the screen of the mobile terminal facing upward. The elastic piece is installed on the housing, and then the protective film is arranged on the film limiting part so that the protective film is positioned and spaced on one side of the screen of the mobile terminal. Since the elastic piece is at the end in the film application pressing direction and holds up the end of the protective film, a gap is formed between the end of the protective film and the screen. When applying the film, the protective film is gradually pressed from the front end to the end in the film application pressing direction. When the protective film is pressed to the end, the elastic piece is deformed by force and gives way, so that the end of the protective film can come out from the front end of the elastic piece, and thus the protective film can be smoothly attached to the mobile terminal. Thus, the front-to-back gradual pasting of the hard protective film is realized, and the problem of gas being trapped between the protective film and the screen to form bubbles is avoided. When applying a soft protective film, the elastic piece is removed, and only through the film limiting part, the protective film can be positioned and spaced on one side of the screen of the mobile terminal. During the film application process, since the soft protective film is relatively soft, its front end can be adhered to the screen first during the bonding process, and the rear end has not fallen off yet, so that it can be gradually pasted from front to back, allowing the gas to be discharged smoothly, and avoiding the problem of gas being trapped between the protective film and the screen to form bubbles. Therefore, this film application tool can achieve front-to-back gradual attachment and smooth exhaust during the process of applying either a soft protective film or a hard protective film, avoiding the formation of bubbles between the protective film and the screen, thereby increasing the types of applicable protective films and improving the practicability of the film applicator.

[0044] Embodiment 1

[0045] like Figure 1 , Figure 3 , Figure 6 As shown, this embodiment proposes a film-applying tool suitable for multiple types of protective films, which is used to apply films to the screens of mobile terminals to be applied with films. The mobile terminals in this embodiment can be various electronic products, such as mobile phones 10, tablet computers, e-books, smart watches and other electronic devices. To facilitate the structural description of this embodiment, the mobile phone 10 is taken as an example for explanation. The long side direction of the mobile phone 10 is the length direction (front and back direction), the short side direction is the width direction (left and right direction), and the thickness direction is the up and down direction. This film-applying tool is used to adhere the protective film 20 to the screen of the mobile phone 10. The protective film 20 can be of different types, such as a soft protective film suitable for curved screen composite materials, a hydrogel protective film 20, and a straight screen tempered protective film 20. It can also be in a variety of forms, for example, one form mainly includes: a film layer 24, a positioning release layer 21, and a tear release layer 25. The film layer 24 (the film that is actually to be attached to the screen surface) is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10; the positioning release layer 21 is detachably arranged on one side of the film layer 24, and the positioning release layer 21 is used to be connected to the self-adhesive film applicator of the flip cover 500. The tear-off release layer 25 is arranged on the side of the film layer 24 away from the positioning release layer 21 and facing the mobile phone 10. When in use, the positioning release layer 21 and the tear-off release layer 25 are both pulled away from the film layer 24, and only the film layer 24 is adhered to the screen surface of the mobile phone 10.

[0046] like Figure 1 , Figure 2As shown, the film sticking tool applicable to multiple types of protective films in this embodiment mainly includes: a shell 100, a film limiting portion 200 and a spring piece 300. The shell 100 generally adopts a square structure. The main function of the shell 100 is to limit the mobile phone 10 to be filmed and the protective film 20, so that the protective film 20 can be aligned with the mobile phone 10 to be filmed. In the specific structure, a receiving cavity 110 is provided in the shell 100, and the opening of the receiving cavity 110 faces upward. A support limiting portion 111 is provided in the receiving cavity 110. The support limiting portion 111 is integrally formed with the shell 100. The support limiting portion 111 is distributed around the receiving cavity 110 and forms a limiting area. For example, the support limiting portion 111 can be a plurality of support blocks or support plates with limiting steps, which respectively abut against the back and the side of the length and width direction of the mobile phone 10 through the limiting steps, thereby limiting the mobile phone 10 to be filmed. It is easy to think that the support limiter 111 can also directly adopt an inner cavity structure, and directly limit the mobile phone 10 placed therein through the inner cavity that matches the size of the mobile phone 10. The diaphragm limiter 200 is set at both ends of the length direction of the housing 100, so that the two ends (front end and rear end) of the length direction of the protective film 20 can be connected, so that the protective film 20 is positioned and spaced on one side of the screen of the mobile phone 10. Through the limiting effect of the diaphragm limiter 200, the entire protective film 20 can be located above the screen of the mobile phone 10, and relatively accurately aligned with the screen of the mobile phone 10. Then the tear-off layer 25 of the protective film 20 is torn off the film layer 24. The tear-off layer 25 will contact the screen of the mobile phone 10 during the tearing process, thereby removing dust from the screen of the mobile phone 10. After the tear-off layer 25 is torn off, the protective film 20 needs to be squeezed along a predetermined direction, so that the protective film 20 gradually adheres to the screen of the mobile phone 10. Usually, it is squeezed from the front end to the rear end along the length direction, so this direction is also the film pressing direction. The front end of the length direction of the shell 100 is in the same direction as the front end of the film pressing direction, and the rear end of the length direction of the shell 100 is in the same direction as the end of the film pressing direction. The elastic piece 300 is detachably connected to the shell 100 and is located at the end of the film pressing direction, and lifts the end of the protective film 20; when the protective film 20 is pressed to the end, the elastic piece 300 is deformed by force and gives way, so that the end of the protective film 20 is out of the elastic piece 300 and attached to the mobile terminal. The elastic piece 300 can be used when affixing a hard film or a soft film, and can avoid the problem that the end of the film is attached to the screen of the mobile phone 10 in advance, causing the gas to be squeezed in the middle.

[0047] like Figure 1 , Figure 3 , Figure 4As shown, a film application tool applicable to multiple types of protective films provided by the present application can implement the film application work of multiple types of protective films 20. When applying a hard protective film, the accommodating inner cavity 110 in the housing 100 is used to accommodate and position the mobile terminal to be film-applied, with the screen of the mobile terminal facing upward. The elastic piece 300 is installed on the housing 100, and then the protective film 20 is arranged on the film limiting part 200, so that the protective film 20 is positioned and spaced on one side of the screen of the mobile terminal. Since the elastic piece 300 is at the end in the film application pressing direction and holds up the end of the protective film 20, a gap is formed between the end of the protective film 20 and the screen. During film application, the protective film 20 is gradually pressed from the front end to the end in the film application pressing direction. When the protective film 20 is pressed to the end, the elastic piece 300 is deformed by force and gives way, so that the end of the protective film 20 can escape from the front end of the elastic piece 300, and thus the protective film 20 can be smoothly attached to the mobile terminal. Thus, the gradual pasting of the hard protective film from front to back is realized, and the problem of gas being trapped between the protective film 20 and the screen to form bubbles is avoided. When applying a soft protective film, the elastic piece 300 is removed, and only through the film limiting part 200 can the protective film 20 be positioned and spaced on one side of the screen of the mobile terminal. During the film application process, since the soft protective film is relatively soft, its front end can be adhered to the screen first during the bonding process, and the rear end has not fallen off yet, so that it can be gradually pasted from front to back, allowing the gas to be discharged smoothly, and avoiding the problem of gas being trapped between the protective film 20 and the screen to form bubbles. Therefore, this film application tool can achieve gradual attachment from front to back, smooth exhaust, and avoid the formation of bubbles between the protective film 20 and the screen during the process of applying either a soft or hard protective film, thereby increasing the types of applicable protective films 20 and improving the practicability of the film applicator. It should be noted that when applying a soft film, the elastic piece 300 can also be retained. During the film application process of the soft protective film, when it is squeezed to the end, the elastic piece 300 is deformed by force and gives way, so that the end of the soft film can escape from the front end of the elastic piece 300, and thus the soft film can be smoothly attached to the mobile terminal.

[0048] As Figure 2 , Figure 4 , Figure 5As shown in the figure, further, the shrapnel member 300 of this embodiment specifically includes: a shrapnel plate body 310 and a protruding plate body 320. The shrapnel plate body 310 can be square, with a relatively large surface area in the horizontal direction, and is detachably connected to the housing 100. The protruding plate body 320 is arranged on the shrapnel plate body 310 and protrudes from the shrapnel plate body 310 towards the front end in the direction of pressing the film. The width of the protruding plate body 320 in the width direction is smaller than the width of the shrapnel plate body in the width direction. The surface area of the protruding plate body 320 is small, so a strong bearing capacity is provided through the shrapnel plate body 310, enabling the protruding plate body 320 to protrude towards the inner cavity 110 and stably located above the screen of the mobile phone 10. The front end of the protruding plate body 320 only extends a short length inside the screen edge. During the film application process, only the edge of the end of the protective film 20 needs to be lifted, so that the protective film 20 will not fall onto the screen of the mobile phone 10 before being pressed to the end.

[0049] As Figure 4 , Figure 5 shown in the figure, further, the front end of the protruding plate body 320 of this embodiment gradually thins along the direction towards the front end in the direction of pressing the film. By adopting the gradually thinning method, the front end of the protruding plate body 320 is easily deformed to make way, and the protruding plate body 320 can be smoothly deformed after being pressed to the rear end. In the specific structure, the upper end surface of the protruding plate body 320 is horizontally arranged while the lower end surface is inclined, so that the thickness of the protruding plate body 320 gradually thins.

[0050] As Figure 4 , Figure 5 shown in the figure, further, two protruding plate bodies 320 are provided in this embodiment. The two protruding plate bodies 320 are arranged at intervals in the width direction on the shrapnel plate body 310. The protruding plate bodies 320 are arranged in the left - right direction and are symmetrically arranged in the width direction, making the support more stable and more convenient to use.

[0051] As Figure 4 , Figure 5 shown in the figure, further, a disassembly and assembly hole 120 is provided on the housing 100 of this embodiment. The disassembly and assembly hole 120 is located outside the inner cavity 110. A plug - in boss 330 is provided on the lower surface of the shrapnel plate body 310. The plug - in boss 330 is embedded in the disassembly and assembly hole 120 so that the shrapnel member 300 is detachably connected to the housing 100. Through the cooperation of the plug - in boss 330 and the disassembly and assembly hole 120, the shrapnel member 300 can be conveniently and quickly plugged onto the housing 100, making the disassembly and assembly more convenient. Two disassembly and assembly holes 120 are adopted, and two corresponding plug - in bosses 330 are provided accordingly. While improving the plug - in stability, the plug - in direction can also be limited, so that the position of the shrapnel member 300 on the housing 100 remains unchanged.

[0052] As Figure 1 , Figure 2As shown, further, the housing 100 of this embodiment is provided with a loading and unloading notch at the edge of the installation position of the spring plate body 310. After the spring piece 300 is installed on the housing 100, the spring plate body 310 covers the loading and unloading notch, so that when removing the spring piece 300, the user's finger can be inserted into the loading and unloading notch to push the spring piece 300 upward, thereby facilitating assembly and disassembly.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, further, an elastic lifting portion 130 is provided on the shell 100 of this embodiment. The elastic lifting portion 130 is located at the front end of the film pressing direction. One end of the elastic lifting portion 130 is connected to the shell 100, and the other end is suspended and movable to form a movable end 131. The movable end 131 of the elastic lifting portion 130 extends toward one side of the accommodating inner cavity 110, and can move downward when squeezed, and rebound upward when not pressed. The movable end 131 is tilted upward, and the front end of the protective film 20 is lifted up by the movable end 131 of the elastic lifting portion 130. After the tear-off layer 25 is torn off, the film layer 24 and the positioning release layer 21 are still located above the screen under the support of the movable end 131 of the elastic lifting portion 130, thereby preventing the film layer 24 from contacting the screen too early. When the pressing and pasting is completed, the film layer 24 of the protective film 20 is adhered to the screen of the mobile phone 10, and the positioning release layer 21 is still connected to the shell 100 through the film limiting part 200. Then, during the return process of the elastic lifting part 130, the positioning release layer 21 on the protective film 20 will be pushed to separate the positioning release layer 21 from the film layer 24 adhered to the screen, so that the positioning release layer 21 can be automatically detached, making the film pasting process more convenient.

[0054] Especially when applying a hard protective film (such as a tempered film), if the spring piece 300 is not used, when the film is pressed from the front end to the end along the film pressing direction, the tempered film is gradually separated from the positioning release layer 21 under the action of the rebound force of the elastic lifting part 130, causing the lower end to contact the screen film in advance, trapping the air in the middle. As the pressing continues to the end, the air cannot be completely discharged, thus forming bubbles. Therefore, by adding a spring piece 300 at the end of the film pressing direction, the end of the tempered film separated from the positioning release layer 21 can be lifted up to avoid air trapping. When pressing toward the end, the front end of the spring piece 300 is deformed downward by force, so that the end of the tempered film falls off the spring piece 300, thereby completing the complete bonding of the tempered film.

[0055] like Figure 1 , Figure 3 , Figure 6 , Figure 7As shown, further, the diaphragm limiting portion 200 of this embodiment includes: a first hook 210 and a second hook 220. The first hook 210 and the second hook 220 are respectively arranged at both ends of the housing 100 in the length direction. The first hook 210 is located on the side of the movable end 131 away from the center of the accommodation inner cavity 110. The first hook 210 is used to connect one end of the protective film 20 in the length direction, and the second hook 220 is used to connect the other end of the protective film 20 in the length direction. In a specific structure, the first hook 210 can be arranged at the front end of the elastic elevation portion 130. The first hook 210 is used to be arranged on the outer side of the mobile phone 10 in the length direction. The first hook 210 and the elastic elevation portion 130 can be integrally formed by injection molding. The elastic elevation portion 130 and the housing 100 can be integrally formed by injection molding. Two first hooks 210 can be arranged at intervals in the width direction. The first hook 210 is used to connect one end of the protective film 20 in the length direction, so that the protective film 20 is positioned above the support limiting portion 111 and is spaced from the mobile phone 10 by a predetermined distance. After the positioning release layer 21 of the protective film 20 is connected to the first hook 210, through the limiting action of the first hook 210, the entire protective film 20 can be located above the screen of the mobile phone 10. Then, the tearing release layer 25 of the protective film 20 is torn off from the film sticking layer 24. During the tearing process, the tearing release layer 25 will contact the screen of the mobile phone 10, thereby removing dust from the screen of the mobile phone 10. After the tearing release layer 25 is torn off, the film sticking layer 24 and the positioning release layer 21 are still located above the screen under the support of the movable end 131 of the elastic elevation portion 130, thereby preventing the film sticking layer 24 from contacting the screen prematurely. The second hook 220 is provided with two along the width direction, so that the first hook 210 and the second hook 220 are respectively used to connect both ends of the protective film 20 in the length direction, so that the protective film 20 is positioned above the support limiting portion 111. A pulling position is formed between the second hooks 220 and above the elastic sheet member 300. The pulling position is used to pull out the tearing release layer 25 of the protective film 20. The tearing release layer 25 of the protective film 20 extends out from the pulling opening for the convenience of the user to hold. The separated tearing release layer 25 is moved out from the pulling opening to expose the film sticking layer 24 on the protective film 20 and align it with the screen of the mobile phone 10 below.

[0056] As Figure 2 、 Figure 6As shown in the figure, further, the width of the movable end 131 of the elastic elevation part 130 of this embodiment gradually increases from front to back in the width direction, forming a dovetail structure. And an elevation boss 140 is provided at the rear end in the length direction of the housing 100, and the second hook 220 is provided on the elevation boss 140, so as to elevate the end of the protective film 20 connected to the second hook 220. During the pasting process of the soft protective film, when the peeling release layer 25 is pulled out and during the downward extrusion process, after the laminating layer 24 and the positioning release layer 21 are gradually separated, due to the softness of the soft protective film, it bends and collapses in the middle under the action of gravity and is prone to contact the screen in advance, thus forming a trapped air situation and resulting in bubbles. To prevent this phenomenon from occurring, the movable end 131 of the elastic elevation part 130 is set in a dovetail shape, so as to widen in the width direction, so that the soft protective film can be supported in the width direction, avoiding the soft protective film from collapsing from both sides in the width direction. Moreover, an elevation boss 140 is provided at the end, so as to increase the step height and increase the suspension height of the protective film 20 from the screen, so as to avoid the situation where the protective film 20 contacts the screen after bending and collapsing from the middle.

[0057] Therefore, this embodiment not only solves the problem that the hard tempered film is prone to fall off at the end of the fitting and touch the screen in advance, but also can solve the problem that the soft composite material film is prone to form a crescent shape with a low middle part and touch the screen in advance. In addition, it can also solve the problem that the hydrogel film is prone to form an irregular arc with both ends low and the middle high in the length direction and the width direction, resulting in multiple parts touching the screen in advance.

[0058] As Figure 1 , Figure 3 , Figure 8 As shown in the figure, further, the film pasting tool of this embodiment further includes a film pressing assembly 400. The film pressing assembly 400 is movably arranged on the housing 100, and the protective film 20 is attached to the mobile terminal by the extrusion of the film pressing assembly 400 that moves along the film pasting pressing direction. The film pressing assembly 400 is used to extrude the protective film 20, so that the protective film 20 is attached to the screen. In the specific structure of the film pressing assembly 400, a scraper structure or a roller structure can be adopted, etc.

[0059] As Figure 1 , Figure 3 , Figure 8 As shown in the figure, to make the pushing process of the film pressing assembly 400 smoother, the film pressing assembly 400 of this embodiment adopts a roller structure.
