Description

Technical Field

[0001] This application belongs to the field of display screen protector application, and particularly relates to a protector applicator. Background Technology

[0002] Electronic device screens, being exposed to the elements, are easily scratched by hard objects, resulting in marks that affect their appearance and even display quality. Therefore, people generally choose to apply screen protectors. To improve application efficiency, screen protector applicators have emerged.

[0003] The film applicator includes a base, a film-fixing structure, and a film-pressing structure mounted on the base. The base has a receiving groove for placing and fixing electronic devices. The film-fixing structure includes a first positioning member and a second positioning member located on the front and rear sides of the receiving groove, which together are used to position the protective film. The film-pressing structure slides with the base and has a pressing surface for pressing the protective film. After the electronic device is placed in the receiving groove and the protective film is positioned by the film-fixing structure, the film-pressing structure is pushed backward, and the pressing surface presses the protective film onto the electronic device to achieve film application.

[0004] Before applying the film, the protective film needs to be positioned above the electronic device; therefore, the film-fixing structure protrudes from the electronic device. To avoid interfering with the placement of the electronic device and the protective film, the pressing structure initially moves to the position of the original receiving slot. Therefore, in the initial state / before applying the film, the pressing structure is located in front of the first positioning member. After the electronic device and the protective film are placed, the pressing structure needs to pass over the first positioning member before applying the film. At this point, the pressing structure bounces because the first positioning member is relatively high, causing inconvenience to the overall film application process and, in severe cases, affecting the quality of the application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this application are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0035] Please combine Figures 1 to 8 The film applicator provided in this application will now be described by way of example.

[0036] A screen protector applicator is used to apply screen protectors to electronic devices. These devices can be mobile phones, tablets, or other electronic products with displays. For a clearer explanation, we'll use a mobile phone as an example.

[0037] The film applicator provided in this application includes a base 10, a film-fixing structure 20, and a film-pressing structure 30. The film-fixing structure 20 is fixed to the base 10 and can be integrally formed from the same material, or it can be fixed to the base 10 by screws or other means. The film-fixing structure 20 is used to position the protective film. The film-pressing structure 30 is slidably connected to the base 10.

[0038] For ease of description, the direction of the screen protector application is defined as from front to back. With the base 10 facing upwards, the phone is placed on the base 10 with the screen facing upwards. The pressing structure 30 moves from front to back to press the protective film onto the phone's screen from front to back, thus achieving screen protector application.

[0039] Please refer to Figure 2 The base 10 includes a base plate 11 and side plates 12 located on the left and right sides of the base plate 11. The base plate 11 and the side plates 12 enclose a receiving cavity 101 for placing a mobile phone. Alternatively, the base plate 11 may be partially recessed to form the receiving cavity 101 for placing a mobile phone, or the base plate 11 may have additional protruding structures to enclose the receiving cavity 101 for placing a mobile phone. No limitation is made here. Each side plate 12 is provided with a slide rail 102, which is slidably connected to the pressure film structure 30.

[0040] Please refer to Figure 3 The film pressing structure 30 includes a support block 33, as well as a pressing member 31 and a sliding member 32 disposed on the support member. The pressing member 31 is generally a roller or scraper, so as to press the protective film onto the mobile phone display screen when it moves with the film pressing structure 30.

[0041] There are two sets of sliding members 32, which slide in correspondence with the slide rails 102 on the two side plates 12 to improve the stability of movement. Generally, the two side plates 12 are symmetrically arranged, and the two sets of sliding members 32 are symmetrically arranged and move synchronously left and right. For ease of description, only one set of sliding members 32 and slide rail 102 will be described in detail.

[0042] Please refer to Figures 1 to 8 The film applicator provided in this application includes a slide 102 comprising a first slide groove and a second slide groove extending forward and backward, and a channel 103 communicating with the second slide groove. A rotating shaft 15 is provided in the first slide groove. The film fixing structure 20 includes a first positioning member 21 and a second positioning member 22 arranged forward and backward. The projection of the first positioning member 21 in the first slide groove is located between the channel 103 and the rotating shaft 15. The sliding member 32 of the film pressing structure 30 includes a first slider 321 and a second slider 322 arranged forward and backward. The first slider 321 slides in contact with the first slide groove, and the second slider 322 slides in contact with the second slide groove. The first slider 321 has a transition hole 301 rotatably connected to the rotating shaft 15 and a passage 302 communicating with the transition hole 301 to allow the rotating shaft 15 to enter the transition hole 301. When the rotating shaft 15 is inserted into the transition hole 301, the film pressing structure 30 can rotate around the rotating shaft 15, causing the second slider 322 to leave the second slide groove through the channel 103.

[0043] In the illustrated structure, the first slider 321 and the second slider 322 share the same slide rail 102 to simplify the structure. That is, the first slide rail and the second slide rail are integrally formed as slide rail 102. In other embodiments, two independent slide rails 102 (the first slide rail and the second slide rail) can also be provided, corresponding to the first slider 321 and the second slider 322 respectively. In this case, the first slide rail and the second slide rail can be arranged parallel vertically, or they can be located on the left and right sides of each side plate 12.

[0044] The film applicator provided in this application features a rotatable film pressing structure 30 with its rotation axis positioned in front of the first positioning member 21. The film pressing structure 30 rotates around the rotation axis, allowing the pressing member 31 to flip upwards to avoid the assembly and positioning operation between the protective film and the first positioning member 21. After positioning the protective film, it rotates in the opposite direction to reset and falls onto the protective film for application. Furthermore, the film applicator provided in this application utilizes the feature of the first slider 321 and the second slider 322 of the film pressing structure 30 being positioned sequentially, with the first slider 321 being part of the rotating structure. Specifically, a rotating shaft 15 is provided on the first slide groove. The first slider 321 has a connecting hole 301 that mates with the rotating shaft 15, and a passageway 302 for the rotating shaft 15 to pass through. As the first slider 321 moves forward with the pressure film structure 30, the rotating shaft 15 passes through the passageway 302 to the connecting hole 301. At this time, the first slider 321 can rotate relative to the rotating shaft 15. The first slider 321 and the rotating shaft 15 form a rotating connection structure between the pressure film structure 30 and the base 10. Furthermore, the presence of the rotating shaft 15 provides a movement limit function for the pressure film structure 30. Specifically, when the pressure film structure 30 moves to the connecting hole 301 and engages with the rotating shaft 15, the rotating shaft 15 restricts the forward movement of the pressure film structure 30, thus achieving movement limit. To prevent the rotation of the pressure film structure 30, the base 10 has a channel 103 to prevent the second slider 322 from leaving the second slide groove. The positions of channel 103 and rotating shaft 15 are adjusted specifically according to the positions of the first slider 321 and the second slider 322. When the first slider 321 is fitted into the rotating shaft 15, channel 103 is located above the second slider 322 to prevent the second slider 322 from moving with the pressure film structure 30.

[0045] In summary, the film applicator provided in this application solves the problem of the film pressing structure 30 jumping when moving by rotating the film pressing structure 30 to avoid the first positioning member 21. Through the coordinated arrangement of the first slider 321, the second slider 322, the first slide groove, the second slide groove, the rotating shaft 15 and the channel 103, the sliding and rotational relationship between the film pressing structure 30 and the base 10 is realized and switched, simplifying the structure and making it highly practical.

[0046] In one embodiment, the first slider 321 has a connecting hole on its side that communicates with the adapter hole 301, forming a passageway 302 for the rotating shaft 15 to pass through.

[0047] In another embodiment, please refer to Figure 7 The first slider 321 is a cylinder with a transition hole 301 formed on its inner wall. The height of the front wall of the cylinder is smaller than that of the rear wall to form a passageway 302. The presence of the front wall obstructs the forward movement of the rotating shaft 15 away from the transition hole 301, while the rear wall restricts the backward movement of the rotating shaft 15 away from the transition hole 301. This limits the three-dimensional movement freedom of the rotating shaft 15 relative to the transition hole 301 under non-external force conditions, leaving it only with rotational freedom. The smaller height of the front wall allows the rotating shaft 15 to enter or leave the transition hole 301 under external force conditions.

[0048] In another embodiment of this application, please refer to Figure 8 The second slider 322 is cylindrical, and its extension direction is parallel to the axis of the rotating shaft 15. The cylindrical shape has an arc surface, which plays a certain guiding role when the second slider 322 enters and exits the second groove through the channel 103, thereby making the operation more convenient.

[0049] Figure 8 In the structure shown, the second slider 322 is beveled on the surface of the channel 103 to form a guide surface 303, so as to facilitate the operation of the second slider 322 being placed into the second groove.

[0050] In another embodiment of this application, the first and second slide grooves are integrally formed. The base 10 includes a base plate 11, side plates 12 on the left and right sides of the base plate 11, and baffles 13 on the upper side of each side plate 12. The first slide groove is formed below each baffle 13. In other words, the first slide groove only has a solid structure of the upper groove wall, and the lower side is empty. By the abutting action of the pressing member 31 and the base 10 / phone, the downward movement of the sliding member 32 is restricted. Therefore, the lower groove wall of the first slide groove does not need to have a solid structure. This configuration can simplify the structure. Those skilled in the art can set the specific structural form of the first slide groove according to the actual situation, and no unique limitation is made here.

[0051] Preferably, the base 10 has a guide strip 14 on the underside of the stop strip 13 for guiding the second slider 322 to the rotating shaft 15. This arrangement facilitates smooth assembly of the second slider 322 and the rotating shaft 15.

[0052] In another embodiment of this application, the pressure film structure 30 rotates about the pivot 15 by an angle of not less than 90 degrees. The rotation angle is greater than or equal to 90° to prevent the protective film from being inserted downwards onto the first positioning member 21 from directly above it. Those skilled in the art can specifically set this angle to 90°, 100°, 125°, 135°, 140°, 150°, 160°, 180°, 200°, 225°, 270°, etc. Figure 3In the structure shown, the film-pressing structure 30 rotates 180°. At this time, the film-pressing structure 30 is roughly flat with the base 10. Setting this state as the packaging and storage state can effectively reduce the height of the film applicator packaging box, thereby reducing the overall space required and reducing logistics and transportation costs.

[0053] In another embodiment of this application, please refer to Figure 3 There are two first positioning elements 21, arranged left and right. There are also two second positioning elements 22, arranged left and right. The two first positioning elements 21 have the same structure, while the two second positioning elements 22 are different to prevent mistaken identification. The two second positioning elements 22 are cylindrical, one with a circular cross-section and the other with an elliptical cross-section.

[0054] The first positioning element 21 is hook-shaped. It can be understood that during the process of applying the film from front to back, the positioning hole at the front end of the protective film is more likely to detach upward from the first positioning element 21. The first positioning element 21 is hook-shaped to avoid this situation.

[0055] In another embodiment of this application, please refer to Figure 6 Each second positioning member 22 includes a first column segment connecting to the base 10 and a second column segment connecting to the first column segment. The cross-section of the second column segment is smaller than that of the first column segment to form a stepped surface 201 that restricts the movement of the protective film toward the base 10. During the process of applying the film from front to back, the positioning hole at the rear end of the protective film is more likely to move downward under the traction of the protective film. The step surface 201 restricts the downward movement of the positioning hole, thereby ensuring that there is a distance between the positioning hole and the mobile phone display screen, so as to avoid the problem of air bubbles easily forming when the rear end of the protective film is attached to the mobile phone display screen too early.

[0056] In another embodiment of this application, the pressing member 31 includes a first pressing member 311 and a second pressing member 312 arranged front to back. The second pressing member 312 is used to press against the planar area of ​​the electronic screen, and the first pressing member 311 is used to press against the curved area of ​​the electronic screen. By setting the film application of the planar area and the curved area of ​​the curved screen to be performed front to back, that is, during the backward movement of the pressing structure 30, the pressing of the curved area lags slightly behind that of the planar area. Utilizing this time difference, the film application of the planar area can be better flattened, and the air is displaced to both sides before the film application of the two curved areas is carried out. In this way, the quality of the film application can be effectively improved.

[0057] Preferably, the second pressing member 312 is a rectangular scraper, and the first pressing member 311 includes scraping portions with protruding ends and a connecting portion connecting the two scraping portions. In other embodiments, the first pressing member 311 is a cylindrical roller, and the second pressing member 312 is a cylindrical connecting cylinder and a frustum connecting the two ends of the connecting cylinder, with the diameter of the frustum decreasing outwards.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the protection scope of this application.
