Description

Technical Field

[0001] This utility model relates to the technical field of screen protector covers, and in particular to a screen protector cover with an improved structure for use on mobile devices. Through specific positioning and a central elastic downward support structure, the screen protector can be preferentially aligned and applied from the center and automatically and evenly applied outwards, thereby improving installation convenience and avoiding air bubble residue. It is suitable for electronic devices with display screens such as mobile phones and tablet computers. Background Technology

[0002] With the widespread use of mobile devices such as smartphones and tablets, screen protectors have become a common accessory to prevent scratches, cracks, or wear on the screen. However, current screen protectors often require users to manually align the protector with the screen and slowly apply it from one end to the entire screen surface. This process is prone to the following problems: 1. Inaccurate alignment: Since the screen protector must be accurately attached to the screen, if the user makes a slight deviation when applying it, it can easily lead to misalignment, resulting in uneven edges or the screen protector not being able to completely cover the screen surface.

[0003] 2. Residual air bubbles: When existing screen protectors are applied, air bubbles often form between the screen and the protector because the air cannot be expelled in time, affecting the viewing experience and touch sensitivity. Even if some screen protectors claim to have an automatic air venting design, it is still difficult to completely avoid the formation of air bubbles, and users often need to scrape them off, increasing the difficulty of installation.

[0004] 3. Cumbersome operation: Current screen protector application methods mostly rely on users to manually adjust the angle and press the screen protector. The process requires careful handling, and if you are not careful, you will have to replace the screen protector, resulting in wasted costs and a poor user experience.

[0005] Based on the above problems, although there are various auxiliary tools or jigs for applying screen protectors on the market, most of them are complex in structure and bulky, making them inconvenient to carry and use, and difficult to balance installation accuracy and air venting effect.

[0006] Therefore, it is necessary to provide an improved screen protector cover structure that can effectively position the mobile device during use and use elastic components to make the screen protector adhere first from the center of the screen and then diffuse outward to release air, so as to achieve the effects of rapid adhesion, avoiding air bubble residue and improving installation accuracy. Utility Model Content

[0007] This utility model relates to a screen protector cover, particularly for the application of screen protectors for mobile devices. It provides a screen protector cover with an improved structure that can be quickly and accurately positioned and can be evenly applied from the center of the screen outwards to effectively vent air.

[0008] This utility model discloses a protective film cover with an improved structure, comprising a main body with a positioning space inside one end face, and a slide rail along the length of the positioning space in the center. A fixing groove is formed along the length of the slide rail at its central position. The outer periphery of the main body has a raised side step surface, and a positioning surface is raised on each side of the side step surface opposite to the slide rail. A frame seat is provided around each positioning surface, and one end of each frame seat has an outlet on the side corresponding to the slide rail. At least one positioning post is provided at predetermined positions on both sides of the slide rail for positioning related components. An elastic cotton strip, in the shape of a long strip, is disposed in the fixing groove, providing a downward pressure source during the application of the protective film through elastic support. A positioning piece is covered on the elastic cotton strip, and its positioning flanges at both ends are fitted into the positioning post through at least one positioning hole, thus securing the positioning piece firmly. A screen protector has its bottom surface adhered to the surface of a positioning piece for accurate alignment, ensuring that the screen protector corresponds to the screen position of the mobile device during application. A release film has an adhesive portion at its bottom, which adheres to the top surface of the screen protector, and one end of the release film extends to form a bend. During operation, the bend gradually forms a reverse bend arc when pulled, allowing the release film to be peeled off sequentially from the screen protector. A pull strip has an adhesive portion at one end, which adheres to the bend of the release film, and the other end of the pull strip forms an extension for the user to pull.

[0009] Therefore, this utility model, through the combined design of the elastic cotton strip, positioning piece, pull strip and release film, can not only improve the positioning accuracy of the protective film, but also effectively realize automatic air release through the central priority bonding mechanism, solving the defects of traditional protective films that are prone to misalignment, air bubbles and inconvenient installation. It has the advantages of simple structure, convenient operation and good bonding effect. Attached Figure Description

Detailed Implementation

[0019] Please see Figures 1 to 8The image shown is a preferred embodiment of the film cover with an improved structure according to the present invention. However, these embodiments are for illustrative purposes only and are not limited to this structure in the patent application. The film cover with an improved structure of the present invention (hereinafter referred to as film cover A) includes: A body 10 has a positioning space 11 inside one end face. A slide rail 15 is provided along the length of the positioning space 11 at its center, and a fixing groove 111 is provided along the length of the slide rail 15 at its center. A side step 12 protrudes from the outer periphery of the body 10, and the inner periphery of the side step 12 forms a side edge 121. Positioning surfaces 13 protrude upwards on both sides of the side step 12 opposite to the slide rail 15, and a frame seat 14 is provided around each positioning surface 13. One end of each frame seat 14 has an outlet 141 on the side corresponding to the slide rail. The inner periphery of each positioning surface 13 forms a positioning side edge 131, and at least one positioning post 16 is provided at predetermined positions on both sides of the slide rail 15 of the body 10.

[0020] An elastic cotton strip 20, which is long and fixedly disposed in the fixing groove 111, preferably, is made of polyurethane (PU) foam.

[0021] A positioning piece 30 has a positioning flange 31 at each end, and each positioning flange 31 has at least one positioning hole 32. The positioning piece 30 is correspondingly covered and disposed on the elastic cotton strip 20, and the positioning hole 32 is respectively sleeved on the positioning post 16 of the body 10 to fix the position of the positioning piece 30.

[0022] A protective film 40 has a top surface 41 and a bottom surface 42, wherein the bottom surface 42 is attached to the surface of the positioning piece 30. The protective film 40 may be made of tempered glass or a scratch-resistant and wear-resistant plastic sheet, and the elastic properties of the elastic cotton strip 20 provide positioning and adhesion pressure for the protective film 40.

[0023] A release film 50 has an adhesive portion 51 at its bottom, which is attached to the top surface 41 of the protective film 40. A bend portion 52 is provided at one end of the release film 50. In actual operation, the bend portion 52 forms a reverse bend arc portion 53 during the removal process, thereby causing the release film 50 to gradually peel off.

[0024] A pull strip 60 has an adhesive part 61 at one end, which is bonded to the turning part 52 of the release film 50, and an extension part 62 at the other end for the user to pull.

[0025] In addition, each of the positioning surfaces 13 has a limiting part 132 at both ends. These limiting parts 132 can be used to surround and position a mobile device B, which includes, but is not limited to, a mobile phone or a tablet computer, and the mobile device B has a screen B1.

[0026] The composition, function, and effects of the above embodiments are described in detail below: Figures 4-8 Cooperate Figure 2 As shown, the release film 50 includes, but is not limited to, a film made of plastic material, and the turning part 52 of the release film 50 is integrally formed with the adhesive part 61 and its extension part 62 of the pull strip 60 or formed by bonding multiple pieces together.

[0027] In use, the user places the mobile device B flat and covers it with the positioning space 11 of the main body 10, so that the protective film 40 corresponds to the surface of the screen B1. At this time, the limiting part 132 can assist in the positioning of the mobile device B.

[0028] Next, the user presses down to hold the main body 10 in place and pulls the extension 62 of the pull strip 60 exposed on the outer edge of the main body 10 with their fingers. At this time, the release film 50 is bent and pulled away from the turning part 52 and gradually separates from the protective film 40, forming a reverse curved part 53. As the release film 50 is pulled away, the reverse curved part 53 gradually moves away from the front end of the protective film 40.

[0029] During the removal of the release film 50, because the elastic cotton strip 20 is placed in the fixing groove 111, the center of the bottom surface 42 of the protective film 40 will preferentially adhere to the center of the screen B1 of the mobile device B under the pressure of the elastic cotton strip 20; at this time, the two sides of the protective film 40 still maintain the support of the positioning piece 30, and present a slightly U-shaped bend.

[0030] Since the positioning piece 30, protective film 40, release film 50, and pull strip 60 are positioned against the side stepped surface 12 of the body 10, an elastic space S1 is formed between the positioning piece 30, protective film 40, release film 50, and pull strip 60 and the inner surface of the body 10. This elastic space S1 maintains a certain height between the body 10 and the screen B1. The positioning edge 131 of the positioning surface 13 maintains a set distance between the screen B1 of the mobile device B and the protective film 40, release film 50, and pull strip 60, forming a downward pressure space S2. Figure 4As shown, the height of the elastic space S1 forms a first gap H1, which is preferably 2-4 mm, and the height of the pressing space S2 forms a second gap H2, which is preferably 1.22 mm. After the central position is first adhered, the protective film 40 will spread outward from the center to both sides, effectively squeezing out air and avoiding residual air bubbles. Finally, the protective film 40 is flat and completely covered on the screen B1 of the mobile device B, achieving the effect of fast and precise adhesion and complete air venting.

[0031] Therefore, this utility model, through the combination structure of the elastic cotton strip 20, positioning piece 30, pull strip 60 and release film 50, can not only improve the positioning accuracy of the protective film 40, but also effectively achieve expansion and air release to both sides through the central priority bonding mechanism, solving the defects of traditional protective films that are prone to misalignment, air bubbles and inconvenient installation. It has the advantages of simple structure, convenient operation and good bonding effect.

[0032] This utility model provides a film cover with an innovative structure and convenient operation, which has significant technological progress and practical value, and is sufficient to overcome the defects of the prior art.
