DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely explained with reference to the drawings in the embodiments of the present invention. Of course, the described embodiments are only some of the embodiments of the present invention, not all of the embodiments. On the premise that those skilled in the art have not performed creative work based on the embodiments of the present invention, all other embodiments obtained fall within the scope of the utility model patent claim of the present invention.

[0017] In Example 1, referring to Figures 1 to 8, the protective film 3 comprises a fixing film 30, a main film 31, and a release film 32, which are arranged from top to bottom. The fixing film 30 has an upper end fixing hole 300 and a lower end fixing hole 301, which fix the fixing film 30, and the release film 32 is peeled off and the main film 31 is attached to the smartphone screen, thereby completing the film attachment process.

[0018] Specifically, a smartphone film attachment structure as shown below is required, which includes a base plate 1, which has a storage groove 10 for storing a smartphone, and which has a storage hole within the storage groove 10 through which the protruding portion on the back of the smartphone is exposed. The arrangement of the storage hole and the storage groove 10 is adjusted according to the sizes of various models of smartphones, and the smartphone film attachment structure for each model is customized to suit each smartphone.

[0019] In this embodiment, the smartphone film attachment structure is a glass film attached to a smartphone with a folding screen, and the glass film of the folding screen is an ultra-thin glass film, specifically an UTG film. This embodiment takes a portrait screen smartphone as an example, but in other embodiments, it may also be a landscape screen smartphone that folds horizontally.

[0020] Two fixing portions are arranged at both ends along the length of the storage groove 10, and the two fixing portions are for fixing the fixing film 30, and the two fixing portions are an upper fixing portion 11 and a lower fixing portion 12, respectively.

[0021] The upper fixing portion 11 has a long fixing groove 13 provided in the base plate 1, and a fixing plate 2 is inserted vertically into the fixing groove 13. The fixing plate 2 has a fixing portion 20 that fits into the fixing groove 13 and a positioning portion 21 that is exposed to the outside from the fixing groove 13. The fixing portion 20 has a chamfer 22 at one end that is inserted into the fixing groove 13, and the position of the chamfer 22 is at both end positions along the length of the fixing groove 13.

[0022] The length of the positioning portion 21 is greater than the length of the fixing groove 13, and the depth of the fixing groove 13 is greater than or equal to the height of the fixing portion 20; that is, a step is formed at the connection between the fixing portion 20 and the positioning portion 21, and after the fixing portion 20 is inserted into the fixing groove 13, the step is attached to the surface of the base plate 1.

[0023] The fixing groove 13 is connected to the mounting groove 14 on one side facing the accommodating groove 10, and the length of the mounting groove 14 is shorter than the length of the fixing groove 13. One end of the fixing part 20 that is inserted into the fixing groove 13 is shorter than the length of the mounting groove 14, and the length of the part of the fixing part 20 that is not removed by the chamfer 22 is longer than the length of the mounting groove 14.

[0024] The chamfers 22 are not only provided to provide space on both sides of the fastener 20 when it is inserted into the mounting groove 13, but also, importantly, to facilitate a rapid insertion process when combined with the mounting groove 14. The width of the mounting groove 14 along the length of the receiving groove 10 is more than twice the thickness of the fastener plate 2. In this embodiment, the fastener plate 2 is 3 mm thick and 15 mm wide. Simply place the fastener 20 into the mounting groove 14, and when a portion of the chamfer 22 fits into the mounting groove 14 and the fastener plate 2 is pushed toward the mounting groove 13, the side walls of the mounting groove 13 will receive the fastener plate 2, allowing it to be inserted into the mounting groove 13 along its inner walls. This entire process requires no alignment, and even visually impaired people can reliably insert the fastener 20 into the mounting groove 13. Operation is simple.

[0025] The positioning portion 21 of the fixing plate 2 has two regulating posts 23 extending from one end away from the fixing portion 20, and is used to regulate the position of the fixing film 30, and the two regulating posts 23 are inserted into the two upper end fixing holes 300, respectively.

[0026] The lower fixing part 12 has two positioning grooves 15, and a fixing post 16 protrudes upward from each positioning groove 15. The depth of the positioning grooves 15 is shallow, and in this embodiment, is one-tenth the length of the fixing post 16.

[0027] When the fixing post 16 is fitted into the lower fixing hole 301, the positioning groove 15 is prepared in advance, allowing the soft fixing film 30 to fit into the positioning groove 15, which effectively increases the area of ​​the fixing region, making it less likely to fall off, and increasing the effective usable length of the fixing post 16 even if the fixing post 16 protrudes the same height from the base plate 1. A locking edge 160 protrudes vertically from the upper end of the fixing post 16, and the locking edge 160 faces away from the upper fixing portion. After the fixing post 16 is fitted into the lower fixing hole 301, the locking edge 160 prevents it from falling off.

[0028] The base plate 1 is provided with slide rails 4 on both sides of the storage groove 10, and also includes slide rollers 5 as accessories. The slide rollers 5 are long and have sliders 54 at both ends that fit into the slide rails 4 and slide. As the sliders 54 slide along the slide rails 4, the slide rollers 5 roll over and press against the fixing film 30, thereby adhering the main film 31 to the smartphone screen.

[0029] The upper end fixing hole 300 has a notch 303 on one side away from the lower end fixing hole 301, the notch 303 is half-cut and can be broken along the notch 303 when subjected to an external force, in this embodiment the notch 303 is a fine hole distributed at intervals, but in other embodiments it may be a score line, and by thinning the relevant portion it can also be broken along the notch 303 when subjected to an external force, and a restriction hole 302 is formed at the other end of the notch 303, and the notch 303 connects the upper end fixing hole 300 and the upper end restriction hole 302.

[0030] In another embodiment, instead of the notch 303, a slide rail may be provided directly.

[0031] The specific application process is as follows: the base plate 1 is placed on a flat surface, the smartphone is placed in the receiving groove 10, the two positioning posts are inserted into the two upper fixing holes 300 of the fixing film 30, and the two fixing posts 16 are inserted into the two lower fixing holes 301, respectively. The slide roller 5 is positioned across the surface of the smartphone, and the sliders 54 on both ends of the roller 51 are inserted into the slide rail 4. The release film 32 is peeled off and the slide roller 5 is pressed downward and upward along the slide rail 4. During this process, the main film 31 is attached to the smartphone screen, the fixing film 30 is torn along the notch 303, and the regulating posts 23 are inserted from the upper fixing holes 300 along the notch 303 into the regulating holes. Once the smartphone film is applied, the smartphone can be removed.

[0032] The slide roller 5 has a long case 50, and sliders 54 are fixed to both ends of the case 50. The sliders 54 are fitted into the slide rail 4 and slidably connected to the slide rail 4. The case 50 opens downward and has rollers 51 connected thereto so that they can roll. The rollers 51 are connected to both ends of the case 50 so that they can roll. A roller core 52 is provided within the roller 51, and the roller 51 is fitted onto the roller core 52. A blind hole 531 is provided at the end of the case 50, into which the end of the roller core 52 is inserted.

[0033] The roller 51 and the roller core 52 are coaxial, and the slider 54 is integrally connected to the end of the case 50. The inner walls at both ends of the case 50 are formed with a connecting plate 53 extending in a direction facing the opening of the case 50, one side of which is perpendicular to the roller core 52, and the slider 54 is located at the end of the connecting plate 53 that is away from the case 50. The connecting plate 53 is provided with a communicating groove 532 that communicates with the blind hole 531. When the roller core 52 slides along the communicating groove 532, the roller 51 can be removed from the case 50, and the roller core 52 is stable within the roller 51. The connecting portion between the blind hole 531 and the connecting groove is narrower than the diameter of the blind hole 531 and the width of the communicating groove 532, forming a restricting portion 533. The diameter of the end of the roller core 52 is smaller than the diameter of the remaining part of the roller core 52, and the roller core 52 is easily removed. The removal end 520 is formed, and the removal end 520 and the regulating portion 533 are tightly fitted together, the diameter of the remaining part of the roller core 52 is larger than the width of the regulating portion 533, so that the roller core 52 cannot be removed, and the distance from the entrance of the blind hole 531 at one end of the case 50 to the bottom of the blind hole 531 at the other end is equal to the distance from the roller core 52 minus the length of the removal end 520, and the length of the removal end 520 is smaller than the depth of the blind hole 531.

[0034] In other words, after the roller core 52 is fitted between the two blind holes 531, a clearance is created between the blind holes 531, but the removal end 520 and the regulating portion 533 are tightly fitted, and when it is necessary to remove the roller core 52 from between the two blind holes 531, the roller core 52 needs to be pressed toward one of the blind holes 531 so that the removal end 520 comes into contact with the regulating portion 533, and the other removal end 520 just reaches the regulating portion 533, and by applying further force against the frictional force, the roller core 52 can be removed. The frictional force is due to the tight fit between the regulating portion 533 and the removal end 520, and the degree of fit between the regulating portion 533 and the removal end 520 can be appropriately adjusted depending on the stretchability of the material.

[0035] The slider 54 has a slide strip 540 protruding from one side facing away from the connecting plate 53, and each slider 54 has two slide strips 540 located on both sides of the slider 54. The slide strips 540 are used for surface finishing during processing; if mechanical errors cause variations in height at both ends of the slider 54 or uneven depths between the two slide rails 4, the surface can be finished simply by polishing the slide strip 540, reducing the risk of reduced yield due to mechanical errors.

[0036] A reinforcing plate 55 is provided inside the case 50, and the reinforcing plate 55 is fixed vertically inside the case 50, and the intersection with the roller 51 is retracted to match the shape of the roller 51.

[0037] A reinforcing rib 530 extends vertically outward from the center of the connecting plate 53 to improve the compressive strength of the connecting plate 53 .

[0038] If the smartphone is of a horizontal folding type, the housing groove 10 can be adapted to the shape of the corresponding smartphone.

[0039] The release film 32 is folded downward near the upper fixing part 11, and then pulled out from the side of the lower fixing part 12, and when peeling off the release film 32, the release film 32 is peeled off by pulling it from the side of the lower fixing part 12.

[0040] The receiving groove 10 has a side wall located at the lower fixing portion 12, which is provided with an elongated through-hole 17 through which the release film 32 passes.

[0041] In Example 2, in this example, a squeegee 6 is arranged, and the squeegee 6 presses the fixing film 30 by squeezing, and scrapes it up from the bottom to the top to complete the film pasting operation. In the smartphone film pasting structure, a roller 51 and a squeegee are provided at the same time, and the squeegee 6 has a handle portion 60 and a squeegee portion 61, and the squeegee portion 61 is a wrapping edge formed by folding and fixing the squeegee 6.

[0042] For user preference, the squeegee 6 and slide roller 5 may be provided simultaneously.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, alterations, and variations can be made to these embodiments without departing from the principles and concepts of the present invention, and the scope of the present invention is limited only by the appended claims and their equivalents.
