Description

Technical Field

[0001] This application relates to the technical field of accessories for electronic devices, and particularly to a protective film assembly and a film application assembly. Background Technology

[0002] Mobile phones, tablets, and other display devices with screens are widely used in people's daily work and life. To protect the screens, protective films are usually applied to the glass surface. Currently, most people apply these films manually, which makes it difficult to guarantee the quality. Problems such as misaligned application or the presence of air bubbles and dust inside the film are common. As a result, screen protector application kits have been invented. However, existing kits are relatively simple in function and lack dust removal capabilities. Before applying the film, existing kits require cleaning the screen to remove dust and prevent fine particles from adhering to the film, which affects the application. This cleaning process is cumbersome. After removing the release liner, the kit is used to position and adhere the film to the screen. However, in practice, the cleaned screen surface easily re-adheres with dust and other impurities during these steps, resulting in dust between the film and the screen after application, affecting the adhesion and ultimately impacting the user experience.

[0003] Therefore, it is necessary to improve the existing film application components to solve the above problems. Summary of the Invention

[0004] In view of this, this application provides a protective film assembly and a film application assembly that can effectively solve the above problems.

[0005] This application provides a protective film assembly, including a protective film, a release film, and a pull strap. The protective film has a first direction and a second direction that are perpendicular to each other. The protective film includes a usable surface and an adhesive surface. The release film covers the adhesive surface of the protective film. The pull strap is stacked on the side of the release film away from the protective film, and one end of the pull strap is connected to the edge of the release film to drive the release film to detach from the protective film. The connection portion between the pull strap and the release film is located at one end in the first direction. The pull strap includes a substrate layer and a protruding structure that protrudes outward from the side of the substrate layer away from the release film. The protruding structure includes a plurality of spaced-apart protrusions, and recesses are formed between the plurality of protrusions. During the process of the pull strap driving the release film to detach from the protective film, the protrusions wipe the screen of the electronic device and push the dust contained in the recesses during the wiping process to detach from the surface of the electronic device screen.

[0006] In one embodiment, the pull strip includes a connecting layer and a wiping pad. The connecting layer is connected to one end of the release film, and the wiping pad includes a substrate layer and the protruding structure. The substrate layer is disposed on the side of the connecting layer opposite to the release film.

[0007] In one embodiment, the depth of the recess is greater than or equal to 0.2 mm.

[0008] In one embodiment, the protrusions extend along the second direction, and a plurality of the protrusions are spaced apart along the first direction, with the recesses formed between every two protrusions.

[0009] In one embodiment, the protrusions are arranged in a row at intervals along the second direction, and the substrate layer has a plurality of rows of the row-shaped protrusions formed along the first direction. The protrusions in adjacent rows are arranged at intervals, and the protrusions in adjacent rows are arranged in an alternating manner.

[0010] In one embodiment, a plurality of the protrusions are intersected and connected to form a mesh structure.

[0011] In one embodiment, the dimension of the substrate layer along the second direction is greater than or equal to the dimension of the protective film along the second direction, and the protrusion structure extends continuously from one end of the substrate layer to the other end along the second direction.

[0012] In one embodiment, the wiping pad includes a wiping portion and a pulling portion, the wiping portion and the pulling portion being arranged and connected along the first direction, and the end of the pulling portion away from the wiping portion extending beyond the protective film.

[0013] In one embodiment, the size of the wiping pad along the first direction is greater than or equal to the size of the protective film along the first direction, the wiping pad extends continuously from one end to the other end of the substrate layer in the first direction, and the wiping portion extends beyond the protective film at the end away from the pulling portion.

[0014] In one embodiment, the combined thickness of the release film and the pull strip is less than or equal to 1.5 mm.

[0015] This application also provides a film application assembly, including a film applicator and a protective film assembly as described above. The film applicator is provided with a receiving groove for accommodating an electronic device. The receiving groove has an installation opening. The protective film assembly is positioned and installed at the bottom of the receiving groove. The protruding structure is located between the protective film and the electronic device.

[0016] In summary, this application provides a protective film assembly and an application assembly.

[0024] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0025] Please also refer to Figures 1 to 3 As shown, this application provides a screen protector assembly 10, which includes an applicator 12 and a protective film assembly 14. The protective film assembly 14 works in conjunction with the applicator 12 to apply a screen protector to an electronic device, such as a mobile phone or tablet computer. In this embodiment, a mobile phone is used as an example for detailed description. Specifically, the protective film assembly 14 includes a protective film 16, a release film 18, and a pull strap 20 connected in sequence. The protective film 16 is applied to the display screen of the electronic device to protect it. The protective film 16 has a usable surface and an adhesive surface. The release film 18 is connected to the adhesive surface and covers it to protect the adhesiveness of the adhesive surface. The pull strap 20 is stacked on the side of the release film 18 away from the protective film 16, and one end of the pull strap 20 is connected to the edge of the release film 18. When the pull strap 20 is pulled, the release film 18 is detached from the protective film 16.

[0026] The pull strap 20 includes a substrate layer and a raised structure 24 protruding outward from the side of the substrate layer away from the release film. The raised structure 24 includes multiple spaced-apart protrusions 26. This design allows the raised structure 24 to wipe the screen of the device to be covered during the film application process, removing small impurities from the screen and enabling simultaneous screen cleaning and film application, simplifying the process. Furthermore, the raised structure 24 includes multiple protrusions 26, with recesses 28 formed between them. The recesses 28 can be grooves or other structures with accommodating cavities, allowing dust and other impurities scraped away by the protrusions 26 to be collected within them, preventing dust from re-adhering to the screen due to lack of storage space and improving cleaning effectiveness. Preferably, the depth of the recesses 28 is designed to be greater than or equal to 0.2 mm, providing sufficient space for dust to be trapped. The protective film assembly 14 and the film application assembly 10 configured with the protective film assembly 14 of this application have a dust removal and cleaning function, which can greatly improve the situation of secondary pollution of the screen by dust and other impurities, improve the film application quality and efficiency, and enhance the user's product experience.

[0027] Furthermore, the pull strip 20 includes a connecting layer and a wiping sheet 22. The connecting layer is connected to one end of the release film 18. The wiping sheet 22 includes a substrate layer and a protruding structure 24. The substrate layer is located on the side of the connecting layer away from the release film 18.

[0028] Preferably, the overall structure formed by the protruding structure 24 is configured to be non-parallel to the moving direction of the wiping pad 22, ensuring that the protruding structure 24 can have a certain extension length in the width direction of the wiping pad 22 perpendicular to its moving direction, thereby increasing the length of the wiping area of ​​the protruding structure 24. From another perspective, it can also be understood that the overall structure formed by the protruding structure 24 forms at least part of an angle with the moving direction of the wiping pad 22, the angle being greater than 0 degrees and less than 180 degrees, preferably 90 degrees; through the design of the angle between the protruding structure 24 and the moving direction of the wiping pad 22, the purpose of the overall structure formed by the protruding structure 24 being non-parallel to the moving direction of the wiping pad 22 is achieved. At least a portion of the protruding structure 24 can be understood as two cases. In one case, the protruding structure 24 may be partially parallel to the moving direction of the wiping pad 22, but the other part needs to be at an angle to the moving direction of the wiping pad 22, so that the entire protruding structure 24 is not parallel to the moving direction of the wiping pad 22. In the other case, the entire protruding structure 24 is at an angle to the moving direction of the wiping pad 22, that is, the protruding structure 24 has no part that is parallel to the moving direction of the wiping pad 22.

[0029] In the illustrated embodiment, the film applicator 12 and the protective film assembly 14 are generally rectangular. According to the illustrated direction, the film applicator 10 is defined to have a length direction a, a width direction b, and a thickness direction c that are perpendicular to each other. The length direction a is the first direction, and the width direction b is the second direction. The film applicator 10 has a first end 10a and a second end 10b that are opposite each other in the length direction a. During the film application process, the pull strap 20 and the wiping pad 22 have a moving direction, which is the direction from the first end 10a toward the second end 10b, that is, the length direction a of the protective film assembly 14.

[0030] More specifically, the wiping pad 22 includes a wiping portion 30 and a pulling portion 32. The wiping portion 30 and the pulling portion 32 are, for example, integrally formed. One end of the wiping portion 30 is connected to one end of the pulling portion 32, and the wiping portion 30 and the pulling portion 32 are connected in a first direction of the wiping pad 22. A protruding structure 24 is disposed on the side of the wiping portion 30 away from the protective film 16. The wiping portion 30 is used to wipe the screen of the electronic device, and the pulling portion 32 is pulled by the user, causing the wiping pad 22 to move along the moving direction to wipe the screen of the electronic device. In other embodiments, the protruding structure 24 may also be disposed on both the wiping portion 30 and the pulling portion 32.

[0031] Preferably, the width of the pulling part 32 is smaller than the width of the wiping part 30, which saves material. The width of the portion connecting the wiping part 30 and the pulling part 32 gradually decreases along the moving direction. The pulling part 32 corresponds to the central area of ​​the wiping part 30 in the second direction. The end of the pulling part 32 away from the wiping part 30 is designed in an arrow shape for easy pulling by the user. The overall shape and size of the pull strap 20 are the same as the wiping pad 22, allowing them to overlap in the thickness direction, increasing the product's aesthetics and synergy of movement.

[0032] More preferably, the width of the wiping portion 30 is equal to the width of the protective film 16, so that the entire screen area on the electronic device covered by the protective film 16 can be swept by the wiping portion 30, improving the cleaning effect. The integral structure formed by the protruding structure 24 extends continuously from one end to the other end of the wiping pad 22 in the second direction. That is, the protruding structure 24 can be a continuous structure in the second direction of the wiping portion 30 to cover the entire width of the wiping portion 30, or it can be a non-continuous structure, such as a multi-segment structure. However, it is necessary to ensure that the projection of the non-continuous structure in the first direction of the wiping portion 30 is continuous. For example, the multi-segment structure can be staggered in the second direction of the wiping portion 30 to cover the entire width of the wiping portion 30, thereby ensuring that the protruding structure 24 leaves no gaps in the second direction of the wiping portion 30, so that the protruding structure 24 can scrape the entire screen of the electronic device, improving the cleaning effect.

[0033] Furthermore, the wiping part 30 has a first edge away from the end of the pulling part 32, and the pull strap 20 has a pulling end 20a and a second edge away from the pulling end 20a. The first edge and the second edge correspond to the same end of the protective film assembly 14, such as the first end 10a. Preferably, the first edge and the second edge are flush and are both flush with the edge of the end of the electronic device screen. The pulling end 20a is the end of the pull strap 20 with the arrow. This arrangement allows the wiping part 30 to sweep the screen of the electronic device from beginning to end, improving the cleaning effect.

[0034] like Figure 5 As shown, in this embodiment, the protrusion 26 extends along the second direction of the wiping pad 22. For example, the protrusion 26 is elongated, and multiple protrusions 26 are evenly spaced along the moving direction of the wiping pad 22, with a recess 28 formed between two adjacent protrusions 26. Preferably, the length of the protrusion 26 along the second direction of the wiping pad 22 is equal to the width of the wiping portion 30, that is, the protrusion 26 has the continuous structure described above, which can cover the entire width of the wiping portion 30. Figure 4 The image shows a front view of the elongated protrusion 26 on the wiping pad 22.

[0035] like Figure 6As shown, in this embodiment, multiple protrusions 26 are arranged in an array. Preferably, the protrusions 26 are columnar, such as cylindrical. Multiple protrusions 26 are arranged in an array along the first and second directions of the wiping pad 22. This is the discontinuous structure described above. Multiple rows of protrusions 26 in the first direction are arranged at intervals, and multiple columns of protrusions 26 in the second direction are arranged in an alternating manner. It is necessary to satisfy that the space between two adjacent protrusions 26 in the second direction can be covered by the corresponding protrusions 26 in an adjacent row. For example, the diameter of the corresponding protrusions 26 in the adjacent row is greater than the distance between two adjacent protrusions 26, so as to cover the entire width of the wiping part 30.

[0036] like Figure 7 As shown, in this embodiment, the protrusion 26 is sheet-like, and multiple protrusions 26 are interconnected to form a mesh structure. Preferably, the protrusion 26 is sheet-like, for example, the protrusion 26 is a scraper structure provided perpendicular to the surface of the wiping pad 22. For example, a portion of the protrusion 26 extends obliquely in one direction, and another portion of the protrusion 26 extends obliquely in another direction. The two portions of the protrusion 26 are interconnected with each other. This case is also the discontinuous structure described above, but multiple protrusions 26 are interconnected with each other to form a continuous structure in the second direction, thereby covering the entire width of the wiping portion 30.

[0037] It should be understood that the three types of protrusion structures 24 described above can be used individually or in combination. Of course, this application is not limited to the shape and arrangement of the three types of protrusion structures 24 described above, and other designs are also possible in other embodiments.

[0038] like Figure 3 As shown, the end of the pull part 32 away from the wiping part 30 extends beyond the protective film 16. This design avoids the wiping pad 22 only raising the gap between the phone and the protective film 16 in a partial area, ensuring that the overall gap between the protective film 16 and the phone remains consistent, thereby improving the film application effect. More specifically, the end of the release film 18 away from the pull end 20a of the pull strap 20 is provided with a first connecting part 34 protruding from the protective film 16. The first connecting part 34 is bent and includes a first part 34a and a second part 34b connected to the first part 34a and bent towards the pull strap 20. The first part 34a and the second part 34b are, for example, integrally molded structures, with the first part 34a connected between the body of the release film 18 and the second part 34b. The pull strap 20 and the wiping pad 22 are respectively provided with a second connecting part 36 and a third connecting part 38 corresponding to the first connecting part 34. One side of the second part 34b is connected to the second connecting part 36, and the other side is connected to the third connecting part 38.

[0039] Preferably, the widths of the first connecting portion 34, the second connecting portion 36, and the third connecting portion 38 are all smaller than the width of the protective film 16, and their dimensions are basically the same. Since the first connecting portion 34 consists of two parts, its length in the first direction is greater than that of the second connecting portion 36 in the first direction. This design, by extending the length of the first connecting portion 34 in the first direction, delays the time it takes for the release film 18 to peel off the protective film 16, ensuring that the release film 18 peels off after the wiping portion 30 begins wiping. This ensures that the sequence of events is: the wiping portion 30 wipes the screen first, then the release film 18 peels off, and finally the protective film 16 is applied to the screen. The sum of the thicknesses of the release film 18, the pull tab 20, and the wiping pad 22 is less than or equal to 1.5 mm. This design avoids a large gap between the protective film 16 and the phone; a gap of less than 2 mm between the phone and the protective film results in a better application effect. A larger gap can cause air bubbles to form during the application of the protective film 16.

[0040] Furthermore, the protective film assembly 14 also includes a positioning film 40, which is used to position and fix the protective film assembly 14 on the applicator 12. The positioning film 40 is connected to the side of the protective film 16 away from the release film 18. The positioning film 40 is provided with a positioning part 42 protruding beyond the protective film 16. The positioning part 42 is provided, for example, on the side of the positioning film 40 corresponding to the first connecting part 34.

[0041] In the illustrated embodiment, as Figure 1 and Figure 2 As shown, the screen protector 12 has a receiving groove 44 on one side for accommodating electronic devices. An installation slot is formed above the receiving groove 44. Both the protective film assembly 14 and the electronic device are installed into the receiving groove 44 through the installation slot. The protective film assembly 14 is positioned at the bottom of the receiving groove 44 by a positioning part 42. A raised structure 24 is disposed between the protective film 16 and the electronic device, and a wiping pad 22 is located on the side of the protective film 16 closest to the installation slot, so that the raised structure 24 contacts the screen of the electronic device. To save materials, the bottom of the receiving groove 44 can be designed as a hollow structure, and some support structures can be provided to support the protective film assembly 14 and the mobile phone. The receiving groove 44 has a positioning groove 46 on the side wall of the first end 10a. The positioning groove 46 is connected to the receiving groove 44. The bottom of the positioning groove 46 is provided with a positioning post 48 and a hook 50. The positioning part 42 is provided with a positioning hole 52 corresponding to the positioning post 48 and a locking hole 54 corresponding to the hook 50. The locking hole 54 is located near the top edge of the protective film 16. When the protective film assembly 14 is installed in the receiving groove 44, the positioning hole 52 is sleeved on the positioning post 48 to realize the installation and positioning of the protective film assembly 14. Three positioning posts 48 and three positioning holes 52 can be provided respectively. The hook 50 is locked in the locking hole 54, which further enhances the positioning and fixing effect. At the same time, the hook 50 also abuts against the top edge of the protective film assembly 14, which plays a limiting role in the protective film assembly 14.

[0042] Furthermore, a pull outlet 56 is provided on the side wall of the receiving groove 44 corresponding to the pull strap 20 and the end of the wiping pad 22 to be pulled, i.e., on the side wall of the receiving groove 44 at the second end 10b. The pull strap 20 and the end of the wiping pad 22 to be pulled are inserted through the pull outlet 56, and the end that is inserted is for the user to pull. The width of the pull outlet 56 is greater than or equal to the maximum width of the wiping pad 22, so that the wiping pad 22 can be pulled out entirely from the pull outlet 56. Preferably, a buckle part 58 is provided at the top of the pull outlet 56, and a locking position 60 is provided on the pull strap 20 and the end of the wiping pad 22 to be pulled. The locking position 60 is, for example, a hole structure. When the protective film assembly 14 is installed in the receiving groove 44, the buckle part 58 and the locking position 60 engage to fix the pull end of the pull strap 20 and the wiping pad 22 before the film application operation, further enhancing the positioning and fixing effect of the protective film assembly 14.

[0043] The following is a brief introduction to the process of applying a screen protector to a mobile phone using the screen protector assembly 10: First, position and fix the screen protector assembly 14 at the bottom of the receiving groove 44, so that the positioning hole 52 is fitted onto the positioning post 48, and the hook 50 is engaged with the locking hole 54. At the same time, the hook 50 abuts against the top edge of the screen protector assembly 14 to limit its movement. Pass the pull strap 20 and the wiping pad 22 to be pulled through the pull outlet 56, and hold the buckle part 58 in the locking position 60. Place the mobile phone screen-down into the receiving groove 44; pull the pull strap 20 and the wiping pad 22 outwards. At the pulled end, the wiping part 30 of the wiping pad 22 moves from the top to the bottom along the mobile phone screen, using the raised structure 24 to scrape away dust and other impurities on the screen for cleaning. At the same time, the pull strap 20 moves and pulls the release film 18 to slowly peel it off the protective film 16. The exposed adhesive surface of the protective film 16 begins to adhere to the screen until the wiping pad 22 and the pull strap 20 are pulled out from the pull outlet 56. The wiping pad 22 completely cleans the screen, the release film 18 is completely peeled off the protective film 16, and the protective film 16 is completely adhered to the screen, completing the screen protector application.

[0044] In summary, this application provides a protective film assembly and an application assembly. The application assembly includes an applicator and a protective film component, which together comprise a protective film, a release film, a pull strap, and a wiping pad. The release film connects the protective film and the pull strap, and the pull strap connects the release film and the wiping pad. The wiping pad has a raised structure on its side away from the protective film. During the application process, the raised structure can scrape away small impurities from the screen of the device to be covered, allowing for simultaneous screen cleaning and protective film application, simplifying the process. The protective film assembly of this application has a dust removal and cleaning function, which can greatly improve the situation of secondary contamination of the screen by dust and other impurities, improve the quality and efficiency of the application, and enhance the user's product experience.
