Description

Technical Field

[0001] This application relates to the field of film application tools, and more specifically, to a side-flipping roller type film applicator and film application kit. Background Technology

[0002] To protect the screens of mobile phones, tablets, and other terminal devices, users typically apply a protective film, such as a tempered glass film or a soft film, to the flat surface of the device to prevent scratches. During the application process, in order to achieve smooth lines and avoid air bubbles, thus maintaining the aesthetic appearance of the terminal device, a screen protector applicator is usually used to assist users in precise positioning and application, thereby improving the application effect.

[0003] During the application of screen protectors to mobile phones, a roller is used to press the protective film, ensuring a firmer adhesion and better results. Currently, the roller is usually separate from the applicator. Before application, the roller is detached from the screen protector housing so the protective film can be installed onto the housing, and then the roller is attached to the housing for rolling. Because the roller and housing require reassembly, some users with limited DIY skills may struggle to assemble them successfully, leading to inconvenience.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this application is to provide a side-flipping roller-type film applicator and film applicator kit, which solves the problem that in the existing technology, the roller and the housing still need to be assembled during the film applicator process, which may cause users to fail to assemble them successfully and cause inconvenience.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] On one hand, this application provides a side-flipping roller-type screen protector applicator, comprising: a housing, an inner cavity provided within the housing, and a supporting and limiting part provided within the inner cavity, the supporting and limiting part being used to accommodate a mobile terminal to which the screen protector is to be applied; wherein the side-flipping roller-type screen protector applicator further comprises:

[0008] An elastic element is located at one end in the longitudinal direction of the accommodating cavity. One end of the elastic element is connected to the housing, and the other end is movably suspended in the accommodating cavity. A first limiting part is provided on the elastic element. The first limiting part is located on the outside of the mobile terminal in the longitudinal direction. The first limiting part is used to connect one end of the protective film in the longitudinal direction so that the protective film is positioned above the supporting limiting part and at a predetermined distance from the mobile terminal.

[0009] The pressing roller component is rotatably disposed at one end of the housing along its length, so as to have a side-flipped state and a pressed film state.

[0010] In the side-tilted state, the roller part of the pressing roller component flips to the outside of the elastic component in the length direction to avoid the first limiting part;

[0011] In the pressure film state, the roller part of the pressing roller is flipped over above the elastic member and can move along the length direction to squeeze the protective film.

[0012] Optionally, the pressing roller component includes: a sliding frame, which is slidably connected to the housing and slides along its length;

[0013] The roller section is rotatably connected to the sliding frame.

[0014] Optionally, the side of the housing is provided with a flipping groove, which forms a sliding outlet at one end in the length direction and a flipping locking position at the other end. The flipping groove is also provided with an inlet and outlet with the opening facing upward.

[0015] The sliding frame includes at least two guide posts spaced apart along its length. When the sliding frame moves into the flipping slot, one of the guide posts is located on the flipping position as a rotation axis, causing the other guide post to rotate out from the inlet / outlet, so as to flip the sliding frame from the top of the housing to the side of the housing.

[0016] Optionally, the inlet and outlet have an arc-shaped inner wall on one side facing the outward direction of the roller portion and an opposite inlet inner wall;

[0017] Along the flipping direction of the pressing roller, the distance between the arc-shaped inner wall and the inlet inner wall gradually increases.

[0018] Optionally, a clearance ramp is provided at one end of the upper surface of the shell along the length direction, and the clearance ramp is located at the inlet and outlet.

[0019] Along the flipping direction of the pressing roller, the clearance slope gradually slopes downward.

[0020] Optionally, a guide rail is provided on the side of the housing in the width direction, the guide rail extends in the length direction, and the turning groove is located on one side of the guide rail in the length direction and is spaced apart from the guide rail to form an inlet and outlet;

[0021] The sliding outlet of the flip-up groove is located below the guide rail, and at least two guide posts slide against the lower surface of the guide rail.

[0022] Optionally, the sliding frame is provided with a limiting mating surface, which is spaced at a predetermined distance from the guide post to form a guide mating position. The guide mating position is used to mate with the housing so that the sliding frame can slide directionally on the housing.

[0023] Optionally, the elastic element includes an elastic plate, which is disposed inclined downward along the length direction toward the outside of the accommodating cavity;

[0024] The first limiting part is set on the elastic plate.

[0025] Optionally, a second limiting part is also provided on the housing, with the first limiting part and the second limiting part located at both ends of the length direction of the housing, respectively;

[0026] The first limiting part and the second limiting part are respectively used to connect the two ends of the protective film in the length direction so that the protective film is positioned above the supporting limiting part.

[0027] On the other hand, this application also proposes a film application kit, which includes a side-flipping roller type film applicator as described above and a protective film;

[0028] The protective film includes: an adhesive layer, a positioning release layer, and a peel-off release layer; the positioning release layer is attached to the side-flipping roller applicator.

[0029] The beneficial effects of the side-flipping roller-type screen protector and screen protector kit provided in this application are at least as follows: First, the pressing roller is flipped to the outside of the housing, thus opening up the space above the housing for convenient placement of the mobile terminal and installation of the protective film. After the mobile terminal to be covered is placed in the support limiting part, the protective film is attached to the first limiting part. The protective film is lifted by the elastic member, thereby maintaining a predetermined distance from the mobile terminal. Before pressing down on the protective film, due to the support of the elastic member, the protective film is lifted and will not fall down and adhere to the screen of the mobile terminal prematurely. Even after tearing off the release layer of the protective film, the protective film can be stably held above the screen of the mobile terminal. Then, the pressing roller is flipped to the upper side of the housing and is in the film-pressing state. In the film-pressing state, the roller part of the pressing roller is flipped above the elastic member and can move along the length direction to compress the protective film. This allows the protective film to be bonded, enabling the pressing rollers to be installed onto the housing for shipment. During use, simply flipping the rollers allows for switching between the side-flipping and pressing states, making operation simpler and more convenient. Attached Figure Description

[0040] Example 1

[0041] like Figure 1 , Figure 2 As shown, this embodiment proposes a side-flipping roller-type screen protector for applying screen protectors to the screens of mobile terminals. The mobile terminal in this embodiment can be a mobile phone 10, or it can be an electronic device such as a tablet computer, e-reader, or smartwatch. For ease of structural description in this embodiment, the long side of the mobile phone 10 is taken as the length direction, the short side as the width direction, and the thickness direction as the vertical direction. For example... Figure 1 , Figure 5 As shown, this side-rolling screen protector applicator is used to adhere the protective film 20 to the screen of the mobile phone 10. The protective film 20 mainly includes: an adhesive layer 24, a positioning release layer 21, and a peel-off release layer 25. The adhesive layer 24 is used to adhere to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10. The positioning release layer 21 is detachably disposed on one side of the adhesive layer 24 and is used to connect to this side-rolling screen protector applicator. The peel-off release layer 25 is disposed on the side of the adhesive layer 24 opposite to the positioning release layer 21 and facing the mobile phone 10. In use, both the positioning release layer 21 and the peel-off release layer 25 are pulled away from the adhesive layer 24, and only the adhesive layer 24 is adhered to the screen surface of the mobile phone 10.

[0042] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment proposes a side-flipping roller-type screen protector, mainly comprising: a housing 100, an elastic element 200, and a pressing roller element 500. The housing 100 has an accommodating cavity 110. The housing 100 is a longitudinal structure matching the shape of the mobile phone 10, thus having length, width, and thickness directions. The opening of the accommodating cavity 110 faces upwards. A supporting and limiting part 120 is provided within the accommodating cavity 110. The supporting and limiting part 120 is integrally formed with the housing 100. The supporting and limiting parts 120 are distributed around the accommodating cavity 110 and form a limiting area. Specifically, a limiting step is formed on the side of the supporting and limiting part 120 facing the limiting area. The limiting step abuts against the back and sides of the mobile phone 10 in the length and width directions, thereby limiting the mobile phone 10 to be covered with the screen protector. The limiting area formed by the supporting and limiting parts 120 can be of different sizes to adapt to different mobile phones. An elastic member 200 is provided on one side of the accommodating cavity 110 along its length. One end of the elastic member 200 is connected to the housing 100, and the other end is movably suspended in the accommodating cavity 110. The movable end of the elastic member 200 extends towards the center of the accommodating cavity 110 and can move downward when compressed and rebound upward when the pressure is released. A first limiting part 300 is provided on the elastic member 200. The first limiting part 300 is used to be located on the outer side of the mobile phone 10 along its length. The first limiting part 300 and the elastic member 200 can be integrally formed by injection molding, and the elastic member 200 and the housing 100 can also be integrally formed by injection molding. The first limiting part 300 is used to connect one end of the protective film 20 along its length so that the protective film 20 is positioned above the supporting limiting part 120 and at a predetermined distance from the mobile phone 10. After the positioning release layer 21 of the protective film 20 is connected to the first limiting part 300, the limiting effect of the first limiting part 300 allows the entire protective film 20 to be positioned above the screen of the mobile phone 10. Then, the peel-off release layer 25 of the protective film 20 is peeled off from the adhesive layer 24. During the peeling process, the peel-off release layer 25 comes into contact with the screen of the mobile phone 10, thereby cleaning the screen. After the peel-off release layer 25 is peeled off, the adhesive layer 24 and the positioning release layer 21 remain above the screen under the support of the movable end of the elastic member 200, thus preventing the adhesive layer 24 from prematurely contacting the screen. Figure 3 , Figure 4 As shown, the pressing roller assembly 500 is rotatably disposed at one end of the housing 100 along its length, allowing it to be in a tilted state and a film-pressing state. Therefore, the pressing roller assembly can be flipped during film application according to different requirements. Figure 1 , Figure 4 As shown, in the side-tilted state, the roller portion 520 of the pressing roller member 500 flips to the outside of the elastic member 200 in the length direction, so as to avoid the first limiting portion 300; as Figure 2As shown, in the pressed film state, the roller portion 520 of the pressing roller member 500 flips over above the elastic member 200 and can move along the length direction to squeeze the protective film 20.

[0043] like Figure 1 , Figure 2 , Figure 4 As shown, this embodiment of a side-flipping roller-type screen protector applicator first flips the pressing roller 500 to the outside of the housing 100, thus opening up the space above the housing 100 for convenient placement of the mobile terminal and installation of the protective film 20. After the mobile terminal to be applied is accommodated by the supporting limiting part 120, the protective film 20 is attached to the first limiting part 300. The protective film 20 is lifted by the elastic member 200, thereby maintaining a predetermined distance from the mobile phone. Before pressing down on the protective film 20, the elastic member 200 supports it, preventing it from shifting and prematurely adhering to the mobile phone screen. Even after tearing off the release layer 25 of the protective film 20, the protective film 20 can be stably held above the screen of the mobile terminal. After flipping the pressing roller 500 to the upper side of the housing 100, it is in a film-pressing state. In the film-pressing state, the roller portion 520 of the pressing roller 500 flips above the elastic member 200 and can move along the length direction to compress the protective film 20. This achieves the adhesion of the protective film 20. In this way, the pressing roller 500 can be installed on the housing 100 for shipment. During use, it is only necessary to flip it over to switch between the side-flipping state and the film-pressing state, making the operation simpler and more convenient.

[0044] like Figure 3 , Figure 4 As shown, the pressing roller component 500 further includes a sliding frame 510 and a roller portion 520. The sliding frame 510 is slidably connected to the housing 100 and slides along its length, while the roller portion 520 is rotatably connected to the sliding frame 510. The roller portion 520 forms a rolling action through rotation. The roller portion 520 can be a rubber roller, foam roller, etc., making it suitable for both soft and hard films. Furthermore, the roller portion 520 can also have a curved profile, allowing for the pressing of curved screens.

[0045] like Figure 3 , Figure 4As shown, the housing 100 further includes a tilting groove 600 on its side. One end of the tilting groove 600 forms a sliding outlet 610, and the other end is closed to form a tilting latch 620. The tilting groove 600 also has an upward-facing inlet / outlet 630. The sliding frame 510 includes at least two guide posts 511 spaced apart along its length. When the sliding frame 510 moves into the tilting groove 600, one guide post 511, located on the tilting latch 620, acts as a rotation axis, causing the other guide post 511 to rotate out from the inlet / outlet 630, thereby tilting the sliding frame 510 from above the housing 100 to the side of the housing 100. For ease of structural description, the structure is illustrated using an example where the tilting groove 600 is located at the front end of the housing 100. In the specific structure, the flip groove 600 is located at the front end of the housing 100, and the sliding outlet 610 faces the rear end. When the sliding bracket 510 slides into the flip groove 600 and flips, it is not necessary to remove the entire sliding bracket 510 when taking out the phone 10 after applying the screen protector. Moreover, before connecting the protective film 20, the flipping also frees up space above the housing 100, making it easier to connect the protective film 20 to the housing 100. When the guide post 511 of the sliding bracket 510 slides along the housing 100 into the flip groove 600, one of the guide posts 511, located on the flipping slot 620, acts as a rotation axis, causing the other guide post 511 to rotate out from the inlet / outlet 630, thus flipping the sliding bracket 510 from the top of the housing 100 to the front of the housing 100. This achieves the flipping function. This eliminates the need to install or remove the pressing roller 500 from the housing 100, making screen protector application more convenient for users.

[0046] like Figure 3 , Figure 4 As shown, the inlet / outlet 630 further comprises an arc-shaped inner wall 631 facing the flip-out direction of the pressing roller 500 and an opposing inlet inner wall 632. Specifically, the inlet / outlet 630 opens upwards, the arc-shaped inner wall 631 is located on the front side, and the inlet inner wall 632 is located on the rear side. The inlet / outlet 630 is formed between the arc-shaped inner walls 631 and the inlet inner wall 632 on both sides, facilitating the entry and exit of the rear guide post 511 into the flip-out groove 600. In this embodiment, the flip-out direction of the pressing roller 500 is an upward-to-front rotational direction. Along the flip-out direction of the pressing roller 500, the distance between the arc-shaped inner wall 631 and the inlet inner wall 632 gradually increases. Therefore, the arc-shaped inner wall 631 on the front side makes the entire inlet / outlet 630 gradually larger, thus facilitating the entry and exit of the rear guide post 511 into the flip-out groove 600.

[0047] like Figure 3 , Figure 4As shown, further, the upper surface of the housing 100 in this embodiment is provided with a clearance ramp 130 at one end along the length direction, and the clearance ramp 130 is located at the inlet / outlet 630; along the flipping direction of the pressing roller 500, the clearance ramp 130 gradually slopes downward. In the specific structure, the clearance ramp 130 can prevent the sliding frame 510 from being exposed during the flipping process of the pressing roller 500, avoiding interference with the rotation trajectory of the sliding frame 510, and ensuring a smoother flipping process for the sliding frame 510.

[0048] like Figure 3 , Figure 4 As shown, further, a guide rail 140 is provided on the side of the housing 100 in the width direction of this embodiment. The guide rail 140 extends along the length direction. A turning groove 600 is located on one side of the guide rail 140 in the length direction and forms an inlet / outlet 630 with the guide rail 140 at a distance. The sliding outlet 610 of the turning groove 600 is located in the lower direction of the guide rail 140, and at least two guide posts 511 abut against the lower surface of the guide rail 140 for sliding. In this embodiment, a limiting mating surface 512 is provided on the sliding frame 510. The limiting mating surface 512 and the guide post 511 are spaced apart by a predetermined distance to form a guiding engagement position. The guiding engagement position cooperates with the housing 100 to allow the sliding frame 510 to slide directionally on the housing 100. In the specific structure, the guiding engagement position formed between the guide post 511 and the limiting mating surface 512 can cooperate with the housing 100 to allow the sliding frame 510 to slide directionally on the housing 100. During the sliding process, the two guide posts 511 are located below the guide rail 140 and are in contact with the guide rail 140. The sliding outlet 610 of the flipping groove 600 is also located below the guide rail 140. After the guide posts 511 slide along the guide rail 140 to the end, they can enter the flipping groove 600. This can achieve stable film pressing and can move into the flipping groove 600 for flipping, so that the side flipping state and film pressing state can be switched smoothly.

[0049] like Figure 1 , Figure 3 , Figure 5 As shown, further, the elastic member 200 in this embodiment includes an elastic plate 210, which is inclined downward along its length toward the outside of the accommodating cavity 110, and a first limiting part 300 is disposed on the elastic plate 210. In the specific structure, the elastic plate 210 is gradually inclined upward along the front to back direction. The movable end of the elastic plate 210 is raised toward the opening direction of the accommodating cavity 110, so that after the first limiting part 300 on it connects with the positioning release layer 21 of the protective film 20, the entire protective film 20 is raised to a higher height, so that there is a sufficient gap between the protective film 20 and the screen of the mobile phone 10. This ensures that even if the film layer 24 is subjected to the pulling force when the release layer 25 is peeled off during the peeling process, it will not stick to the screen of the mobile phone 10, thereby better ensuring that it will not stick prematurely.

[0050] like Figure 1 , Figure 3 , Figure 5 As shown, in this embodiment, the housing 100 is further provided with a second limiting part 400. The first limiting part 300 and the second limiting part 400 are respectively located at both ends of the length direction of the housing 100. The first limiting part 300 and the second limiting part 400 are respectively used to connect the two ends of the protective film 20 in the length direction, so that the protective film 20 is positioned above the supporting limiting part 120. The first limiting part 300 is located at the front end of the housing 100, and the second limiting part 400 is located at the rear end of the housing 100. Through the combined action of the first limiting part 300 and the second limiting part 400, the protective film 20 can be accurately positioned. In the specific structure, the first limiting part 300 includes two first hooks 310 spaced apart in the width direction, and the second limiting part 400 includes a second hook 410 located in the middle of the width direction. In the specific structure, a supporting horizontal plate 150 is provided at the rear end of the housing 100, and the second hook 410 is provided on the supporting horizontal plate 150 and used to connect the other end of the protective film 20 in the length direction. A pull-out opening 151 is formed below the support plate 150 for pulling out the peel-off release layer 25 of the protective film 20. The peel-off release layer 25 of the protective film 20 extends from the pull-out opening 151 for easy grip by the user, allowing the peel-off release layer 25 to be removed from the pull-out opening 151, thus exposing the film layer 24 on the protective film 20 and aligning it with the screen of the mobile phone 10 below.

[0051] like Figure 1 , Figure 5 As shown, a pull hole 22 is provided on one end of the positioning release layer 21 of the protective film 20. The film can be hung on the first hook 310 through the pull hole 22. The two first hooks 310 can limit the protective film 20 in the width direction, allowing it to align with the mobile phone 10 below. By matching the pull hole 22 and the first hooks 310 and hooking them in place, the film can be aligned with the mobile phone 10 in the length direction. The second hook 410 hooks and limits the other end of the positioning release layer 21 of the protective film 20. The limiting hole 23 at the other end of the protective film 20 is fitted onto the second hook 410. Thus, the second hook 410 and the first hook 310 prevent the protective film 20 from moving in the width direction, and allow it to move only a predetermined distance or remain stationary in the length direction (facilitating the downward pressure of the film layer 24), achieving more stable positioning.

[0052] Example 2

[0053] like Figure 1 , Figure 5As shown, this embodiment provides a screen protector kit, including the side-flip roller screen protector applicator and a protective film 20 as described above. The protective film 20 in this embodiment specifically includes: a film layer 24, a positioning release layer 21, and a peel-off release layer 25. The film layer 24 is used to adhere to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10. The positioning release layer 21 is detachably disposed on one side of the film layer 24 and is used to connect to the side-flip roller screen protector applicator. One end of the positioning release layer 21 in the length direction is provided with a pull hole 22, and the other end is provided with a limiting hole 23. The pull hole 22 is an oblong hole, allowing it to be fitted onto the first hook 310. The limiting hole 23 is used to fit onto the second hook 410 for positioning. The peel-off release layer 25 is disposed on the side of the film layer 24 opposite to the positioning release layer 21 and facing the mobile phone 10.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
