Description

Technical Field

[0001] This application relates to the field of screen protector application tools, and more specifically, to a push-type screen protector applicator and screen protector application kit. Background Technology

[0002] To protect the screens of mobile devices such as phones and tablets, users typically apply a screen protector to the flat surface of the device (the one to be covered) to prevent scratches. During the application process, to achieve smooth lines and avoid air bubbles, thus maintaining the aesthetic appearance of the device, a screen protector applicator is usually used to assist the user in precise positioning and application, thereby improving the application effect.

[0003] There are screen protector applicators on the market that use pressing components (rollers or scrapers). For example, the rollers press the protective film to better adhere it to the screen of the mobile device. Some users press the rollers against one end of the applicator, causing the protective film to be pressed down by the rollers. This pressed-down protective film is easily pressed and adheres to the screen of the mobile device before the application begins. This adhesion before the rollers push and press can easily create air bubbles, resulting in poor application.

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

[0005] The purpose of this application is to provide a push-type screen protector applicator and screen protector kit, which solves the problem in the prior art where the extruder presses down on one end of the protective film, causing that end to stick to the screen of the mobile terminal first, which easily generates air bubbles and results in poor screen protector application.

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

[0007] On the one hand, this application provides a push-type film applicator for applying protective film to a mobile terminal. The push-type film applicator includes: a housing, a first surface of the housing having an accommodating cavity for accommodating the mobile terminal, and a first limiting member at the first end of the housing in the length direction.

[0008] A shrinkable elastic structure is provided at the second end of the shell along its length and can shrink and deform along its length. A second limiting member is provided on the shrinkable elastic structure. The first and second limiting members are used to connect the protective film, respectively.

[0009] The lifting elastic structure is located between the shrinking elastic structure and the accommodating cavity, and can be pressed down and deformed in the vertical direction.

[0010] And an extrusion component, which is slidably disposed on the housing along its length and has an initial pressure state located between the lifting elastic structure and the contraction elastic structure;

[0011] In the initial pressure state, the extruder is used to press down the protective film, and the protective film is lifted by the lifting elastic structure to create a predetermined gap between the second end and the mobile terminal.

[0012] In an optional embodiment, a hollow hole is provided on the outer side of the accommodating cavity on the housing, and the lifting elastic structure includes: a spring pressing platform, the spring pressing platform having a movable end, one end of the spring pressing platform opposite to the movable end being fixedly disposed on the housing, and the movable end being suspended in the hollow hole and protruding from the first surface;

[0013] The movable end is used to lift up the protective film.

[0014] In an optional embodiment, the compression table includes: a first inclined surface, the first inclined surface being located on the side of the compression table facing the contractile elastic structure, and the inclined surface gradually rising in the length direction along the direction of the contractile elastic structure toward the accommodating cavity;

[0015] The right-angled surface is located on the side of the spring-loaded platform facing the inner cavity;

[0016] The first inclined surface and the right-angled surface are smoothly connected at the top by a circular arc surface;

[0017] A receiving area is formed between the first inclined surface and the shrinkage elastic structure, which is used to accommodate the extrusion in the initial pressure state.

[0018] In an optional embodiment, the shrink-elastic structure includes a bending portion, one end of which is connected to a second end of the housing;

[0019] A support platform is connected to the end of the bent portion away from the inner cavity, and a second limiting member is set on the support platform;

[0020] The support platform moves closer to or further away from the accommodating cavity in the first direction by bending at the bend.

[0021] In an optional embodiment, the bending portion includes a bending plate connected to the second end of the housing and forming a U-shaped groove with the opening of the U-shaped groove facing upward.

[0022] The width of the opening of the U-shaped groove is greater than the width of the bottom of the U-shaped groove.

[0023] In an optional embodiment, guide rails are provided on both sides of the housing in the width direction, and the guide rails extend along the length direction, with the two sides of the extrusion member respectively movably connected to the guide rails on both sides.

[0024] The guide rail has an insertion port on one side of the first end, and the extruder moves toward the second end by being inserted through the insertion port to movably connect to the guide rail.

[0025] In an optional embodiment, the upper surface of the guide rail is flush with the first surface;

[0026] A transition boss is provided at the end of the guide rail facing the insertion port, and the transition boss protrudes from the first surface;

[0027] The surface of the transition boss gradually decreases towards one end of the guide rail and smoothly connects with the upper surface of the guide rail;

[0028] The insertion port is located on the outer side of the transition boss in the width direction.

[0029] In an optional embodiment, the extrusion member includes: a sliding frame, with sliding connecting portions on both sides of the sliding frame, the sliding connecting portions being sleeved on the guide rail and sliding along the length direction;

[0030] The extrusion section is connected to the sliding frame;

[0031] The extrusion section includes a rolling roller or an extrusion block.

[0032] In an optional embodiment, end bosses are provided on both sides of the shell along its length, and the upper surfaces of the end bosses on both sides protrude from the first surface of the shell. The first limiting member is provided on the upper surface of the end boss at the first end.

[0033] A tear-off opening is provided below the end boss at the first end;

[0034] The width of the end bosses on both sides is greater than the width of the middle part of the shell.

[0035] On the other hand, this application also proposes a film application kit, which includes a push-type film applicator as described above and a protective film;

[0036] The protective film includes: an adhesive layer, a positioning release layer, and a peel-off release layer; the positioning release layer is connected to the first limiting member and the second limiting member.

[0037] The beneficial effects of the push-type screen protector and screen protector kit provided in this application are at least as follows: By setting a first limiting member at the first end of the shell along its length and a shrinkable elastic structure at the second end of the shell along its length, and by connecting the protective film to the first limiting member via a second limiting member on the shrinkable elastic structure, the protective film can be stretched out along its length. Before the application begins, the extruder can slide from the first end to the second end of the shell and be positioned between the shrinkable elastic structure and the lifting elastic structure, thus placing the extruder in a pre-application pressure state. At this time, although the protective film is pressed down at the second end by the extruder, under the action of the lifting elastic structure, the protective film is lifted by the lifting elastic structure near the accommodating cavity, thus maintaining a predetermined gap between the protective film and the mobile terminal. This facilitates dust removal from the mobile terminal's screen within this gap during the peeling and pulling out of the release layer. After the release liner of the protective film is peeled off, the protective film is exposed and faces the screen. The extruder is pushed from the second end towards the first end, putting the film in a pressed state. The lifting elastic structure deforms and moves downwards under the pressure of the extruder, pressing down the protective film. This downward pressure causes the shrinking elastic structure to contract, allowing the protective film to deform downwards. This allows the film layer to smoothly move down and contact the screen of the mobile terminal, gradually pressing and adhering it to the screen from the second end to the first end. This prevents the film layer from being damaged by excessive compression and deformation during the downward movement, making the application process smoother. Once the film layer is fully adhered to the screen, the extruder is removed, and the shrinking elastic structure returns to its original position. This allows the positioning release liner of the protective film to move upwards and detach from the screen, making it easy for the user to peel off. This improves the application effect and makes the application process more convenient. Attached Figure Description

[0051] Example 1

[0052] like Figure 1 , Figure 2 As shown, this embodiment proposes a push-type screen protector applicator for applying a screen protector to the screen of a mobile terminal. The mobile terminal in this embodiment can be various electronic products, such as a mobile phone 10, a tablet computer, an e-reader, a smartwatch, or other electronic devices. For ease of structural description, a mobile phone 10 is used as an example. The long side of the mobile phone 10 is the length direction (front-to-back direction), the short side is the width direction (left-to-right direction), and the thickness direction is the vertical direction. The length direction, width direction, and vertical direction mentioned below are all based on this principle for structural description. Figure 2 , Figure 6 As shown, in this embodiment, the push-type screen protector applicator is used to adhere the film portion of the protective film 20 to the screen of the mobile phone 10. The protective film 20 can take various forms, for example, one form mainly includes: an adhesive layer 22, a positioning release layer 23, and a peel-off release layer 21. The adhesive layer 22 (the film that is actually applied to the screen surface) 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 23 is detachably disposed on one side of the adhesive layer 22, and the positioning release layer 23 is used to connect to this dust-removing screen protector applicator with an elastic structure. The peel-off release layer 21 is disposed on the side of the adhesive layer 22 opposite to the positioning release layer 23 and facing the mobile phone 10. In use, both the positioning release layer 23 and the peel-off release layer 21 are pulled away from the adhesive layer 22, and only the adhesive layer 22 is adhered to the screen surface of the mobile phone 10.

[0053] like Figure 1 , Figure 2 , Figure 3As shown, the push-type screen protector of this embodiment mainly includes: a housing 100, a shrinking elastic structure 200, a lifting elastic structure 300, and a pressing member 400. The housing 100 can be configured as a square structure. When in use, the housing 100 is laid flat. On the upward-facing side of the housing 100, there is a first surface 110. An accommodating cavity 120 is provided on the first surface 110, that is, the opening of the accommodating cavity 120 is located on the first surface 110. The accommodating cavity 120 is used to accommodate the mobile phone 10 to which the screen protector is to be applied. A first limiting member 130 is provided at the first end 101 in the length direction of the housing 100. The first end 101 can be the rear end, and the second end 102 can be the front end. A shrinkable elastic structure 200 is integrally formed and disposed at the second end 102 of the shell 100 in the length direction, and can shrink and deform in the length direction. The shrinkable elastic structure 200 is located on the outside of the accommodating cavity 120. A second limiting member 140 is provided on the shrinkable elastic structure 200. The first limiting member 130 and the second limiting member 140 are respectively used to connect the protective film 20. Specifically, the first limiting member 130 and the second limiting member 140 are respectively connected to the positioning release layer 23 of the protective film 20 at the rear end and the front end, so that the protective film 20 is limited and connected to the shell 100, and the protective film 20 faces upward, while the mobile phone 10 is located below the protective film 20. The protective film 20 and the screen of the mobile phone 10 are spaced a predetermined distance apart by the elastic expansion of the contractile elastic structure 200. That is, when the two ends of the positioning release layer 23 of the protective film 20 are connected to the first limiting member 130 and the second limiting member 140, the contractile elastic structure 200 opens and the protective film 20 is tightened, thereby creating a dust removal space between the protective film 20 and the screen of the mobile phone 10. This facilitates the removal of dust from the screen of the mobile phone 10 during the pulling-out process of the release layer, achieving a dust removal effect. The lifting elastic structure 300 is disposed between the contractile elastic structure 200 and the accommodating cavity 120 and can be pressed down and deformed in the vertical direction. The extrusion member 400 is slidably disposed on the housing 100 along the length direction and has an initial pressure state located between the lifting elastic structure 300 and the contractile elastic structure 200. When the extruder 400 is located between the lifting elastic structure 300 and the shrinking elastic structure 200, the protective film 20 is pressed under the extruder 400. The protective film 20 is lifted by the lifting elastic structure 300 and a predetermined gap is formed between the second end 102 and the mobile phone 10. In this way, even under the extrusion of the extruder 400, the predetermined gap can still be formed by the lifting elastic structure 300, thereby achieving the dust removal effect.

[0054] like Figure 1 , Figure 2 , Figure 3As shown, in this embodiment, a push-type film applicator is provided with a first limiting member 130 at the first end 101 along the length of the housing 100, and a shrinkable elastic structure 200 at the second end 102 along the length of the housing 100. A protective film 20 is connected to the first limiting member 130 via a second limiting member 140 on the shrinkable elastic structure 200, allowing the protective film 20 to be stretched out along its length. Before film application begins, the extruder 400 can slide from the first end 101 to the second end 102 of the housing 100 and be positioned between the shrinkable elastic structure 200 and the lifting elastic structure 300, thus placing the extruder 400 in a pre-application pressure state. At this time, although the protective film 20 is pressed down by the extruder 400 at the second end 102, under the action of the lifting elastic structure 300, the protective film 20 is lifted by the lifting elastic structure 300 at the position close to the inner cavity 120, so that the protective film 20 and the mobile phone 10 are still separated by a predetermined gap, which makes it convenient for the release layer 21 to remove dust from the screen of the mobile phone 10 in the gap during the pulling process. After the release layer 21 of the protective film 20 is torn off, the protective film 20 is exposed and faces the screen. The extrusion member 400 is pushed from the second end 102 toward the first end 101, and the film is in a pressing state. At this time, the lifting elastic structure 300 deforms and moves downward under the pressure of the extrusion member 400, thereby pressing down the protective film 20 on it. The downward pressure of the protective film 20 causes the shrinking elastic structure 200 to shrink under force, so that the protective film 20 has a downward deformation margin, so that the film layer 22 of the protective film 20 moves down smoothly and comes into contact with the screen of the mobile phone 10. Then, the film layer 22 of the protective film 20 is gradually squeezed and adhered to the screen in the direction from the second end 102 to the first end 101. In this way, the film layer 22 will not be damaged by large compression deformation during the downward movement, making the film application process smoother. After the protective film 20's adhesive layer 22 is fully adhered to the screen of the mobile phone 10, the extruder 400 is removed, and the elastic structure 200 retracts and returns to its original position. This allows the positioning release layer 23 of the protective film 20 to move upward and detach from the adhesive layer 22 on the screen, making it easier for the user to peel off the positioning release layer 23. This improves the film application effect and makes film application more convenient.

[0055] Therefore, when using the extruder 400 (roller or scraper) for film application, after the user installs the protective film 20 on the applicator, they can first install the extruder 400 on the applicator and push it from the first end 101 to the second end 102 of the housing 100, performing a push-pull motion once. This checks the tightness of the connection between the extruder 400 and the applicator, ensuring smooth pushing and pulling. After confirming that the tearing is relatively smooth, the release layer 21 of the protective film 20 is then peeled off. After the release layer 21 is removed, the extruder 400 is pushed from the second end 102 towards the first end 101 to compress the protective film 20. This two-stage push-pull motion of the extruder 400 reduces the risk of uneven movement during its movement and improves the success rate of film application.

[0056] like Figure 1 , Figure 3 As shown, further, in this embodiment, a perforated hole 103 is provided on the outer side of the accommodating cavity 120 on the housing 100. The perforated hole 103 can be formed on the first surface 110. The lifting elastic structure 300 specifically includes: a spring-loaded platform 310, which has a movable end 320. One end of the spring-loaded platform 310 opposite to the movable end 320 is fixedly disposed on the housing 100. The movable end 320 is suspended in the perforated hole 103 and protrudes from the first surface 110. By making the movable end 320 protrude upward from the first surface 110, the protective film 20 can be lifted, so that the position of the protective film 20 near the accommodating cavity 120 can be lifted away from the screen of the mobile phone 10 below.

[0057] like Figure 1 , Figure 3 , Figure 4 As shown, the spring-loaded platform 310 of this embodiment further includes a first inclined surface 311 and a right-angled surface 312. The first inclined surface 311 is located on the side of the spring-loaded platform 310 facing the contractile elastic structure 200, and gradually rises along the direction of the contractile elastic structure 200 toward the accommodating cavity 120 in the length direction; the right-angled surface 312 is located on the side of the spring-loaded platform 310 facing the accommodating cavity 120, and the first inclined surface 311 and the right-angled surface 312 are connected smoothly at the top by an arc surface; a receiving area is formed between the first inclined surface 311 and the contractile elastic structure 200, and the receiving area is used to accommodate the extruded member 400 in the initial pressure state. The first inclined surface 311 is used for the inclined setting so that the inner wall of the receiving area can match the shape of the extruded member 400. In addition, when the extruded member 400 is pushed toward the first end 101, the first inclined surface 311 provides guidance, making the pushing process of the extruded member 400 easier.

[0058] like Figure 1 , Figure 3 , Figure 4As shown, the shrinkable elastic structure 200 of this embodiment further includes a bending portion 210 and a support platform 220. One end of the bending portion 210 is connected to the second end 102 of the housing 100, and the support platform 220 is connected to the end of the bending portion 210 away from the accommodating cavity 120. A second limiting member 140 is disposed on the support platform 220. The support platform 220 moves closer to or further away from the accommodating cavity 120 in a first direction due to the bending of the bending portion 210. After the second limiting member 140 and the first limiting member 130 are connected to the protective film 20, the protective film 20 is compressed by the extruder 400, thereby compressing the bending portion 210 and moving the support platform 220 toward the first end 101 of the housing 100. This reduces the distance between the first limiting member 130 and the second limiting member 140 in the length direction, thereby giving the protective film 20 a downward displacement allowance. The bending portion 210 can adopt various structures, such as a complete bending elastic plate in the width direction or multiple bending elastic plates spaced apart in the width direction, etc.

[0059] like Figure 1 , Figure 3 , Figure 4 As shown, further, the bending portion 210 of this embodiment includes a bending plate 211, which is connected to the second end 102 of the housing 100 and forms a U-shaped groove 212. The opening of the U-shaped groove 212 faces upward; the width of the opening of the U-shaped groove 212 is greater than the width of the bottom of the U-shaped groove 212. By using U-shaped bending plates 211 for connection, a stable elastic force can be generated. The groove width (the distance between the inner walls in the length direction) between the U-shaped grooves 212 provides a moving position for the movement of the support platform 220, enabling the support platform 220 to have stable movement and reset functions. In this embodiment, the width of the opening of the U-shaped groove 212 is greater than the width of the bottom of the U-shaped groove 212, and the width of the opening at the top of the U-shaped groove 212 is greater than the width of the bottom of the groove at the bottom, so that the upper end of the bending portion 210 can generate a larger deformation, thereby increasing the moving distance of the support platform 220 and improving the elastic performance of the bending plate 211.

[0060] like Figure 6 , Figure 8 As shown, further, guide rails 150 are provided on both sides of the housing 100 in the width direction of this embodiment. The guide rails 150 extend along the length direction, and the two sides of the extrusion member 400 are movably connected to the guide rails 150 on both sides. An insertion port 151 is formed on one side of the guide rail 150 at the first end 101. The extrusion member 400 moves toward the second end 102 by being inserted through the insertion port 151 to movably connect to the guide rail 150. By providing an insertion port 151 at the first end 101 of the housing 100, it is convenient to push the extrusion member 400 from the insertion port 151 toward the second end 102, so that the extrusion member 400 can be quickly connected to the housing 100 and slide stably along the length direction by being guided by the guide rails 150. Figure 7As shown, the insertion port 151 is set at the first end 101, so that the extruder 400 is installed at the first end 101 of the housing 100 in the initial state. In the initial state, the extruder 400 is pushed toward the second end 102 to check whether the sliding of the extruder 400 is flexible and smooth. When the extruder 400 reaches the second end 102, the extruder 400 is in the initial pressure state.

[0061] like Figure 6 , Figure 8 As shown, further, the upper surface of the guide rail 150 in this embodiment is flush with the first surface 110. A transition boss 160 is provided at one end of the guide rail 150 facing the insertion port 151, and the transition boss 160 protrudes from the first surface 110. The surface of the transition boss 160 gradually decreases towards the end of the guide rail 150 and smoothly connects with the upper surface of the guide rail 150. The insertion port 151 is located on the outer side of the width direction of the transition boss 160. In the specific structure, the transition boss 160 first lifts the extrusion member 400. During the process of pushing towards the second end 102, the connection of the extrusion member 400 slowly slides from the upper surface of the transition boss 160 to the upper surface of the guide rail 150. In this way, the extrusion member 400 is guided when it first contacts the guide rail 150 and gradually moves onto the rail, avoiding the extrusion member 400 from being directly fitted onto the rail, which would cause the extrusion member 400 to be squeezed too tightly on the housing 100 or the screen of the mobile phone 10 and thus be unable to be pushed.

[0062] like Figure 1 , Figure 6 , Figure 8 As shown, the extrusion member 400 in this embodiment further includes a sliding frame 410 and an extrusion part 420. Sliding connecting parts 430 are provided on both sides of the sliding frame 410. The sliding connecting parts 430 are sleeved on the guide rail 150 and slide along its length. The extrusion part 420 is connected to the sliding frame 410. The extrusion member 400 extrudes the protective film 20, thereby stabilizing the force during the film application process. For example, by extruding from front to back with the extrusion member 400, air bubbles can be effectively avoided. The sliding connecting part 430 in this embodiment includes an upper limit block 431 and a lower limit block 432. A mating gap is formed between the upper limit block 431 and the lower limit block 432. The guide rail 150 is inserted into the mating gap, so that the upper limit block 431 abuts against the upper surface of the guide rail 150, and the lower limit block abuts against the lower surface of the guide rail 150, thereby allowing the sliding connecting part 430 to slide stably on the guide rail 150.

[0063] The extrusion section 420 can be a roller or an extrusion block. When the extrusion section 420 is a roller, the rolling action is achieved by rotating the roller. The roller can be a rubber roller, a foam roller, etc., making it suitable for both soft and hard films. Additionally, the roller can have a curved profile to extrude curved screens. The extrusion section 420 includes an extrusion block, which is fixedly connected to the sliding frame 410. When the extrusion section 420 is an extrusion block, the pushing action of the extrusion block creates a pushing action. The extrusion block can be a rubber strip, a foam strip, etc., making it suitable for both soft and hard films. Additionally, the extrusion block can have a curved profile to extrude curved screens.

[0064] like Figure 1 , Figure 5 , Figure 6 As shown, further, in this embodiment, end bosses 170 are provided on both sides of the length direction of the housing 100. The upper surfaces of the end bosses 170 on both sides protrude from the first surface 110 of the housing 100, and the first limiting member 130 is provided on the upper surface of the end bosses 170 of the first end 101.
