Technical Field
[0001] This utility model relates to the field of film application technology, and in particular to a film scraping component and film application box. Background Technology
[0002] Screen protector cases are generally equipped with a squeegee assembly that can move relative to the case body. The squeegee assembly includes a slider and a squeegee block. In order to adapt to curved screens, the squeegee block in the past had protrusions on both sides along the length to squeeze the curved part of the curved screen, and the part between the two protrusions was used to squeeze the flat part of the curved screen. Although this type of squeegee block can adapt to curved screens, consumers have reported that it often causes air bubbles.
[0003] The experiment revealed that the reason why the bubbles could not be completely removed was due to processing errors. Sometimes the scraping block would contact the curved part first and then the flat part, which would lead to the formation of bubbles.
[0004] To solve this technical problem, researchers developed a scraping assembly, which includes a first scraping block and a second scraping block of the same thickness. The first scraping block is used to extrude the flat part, and the second scraping block is installed on the back side of the first scraping block to extrude the curved part. This can effectively reduce the generation of air bubbles. The drawback of this scraping assembly is that the sliding scraping assembly requires a relatively large amount of force. Utility Model Content
[0005] The technical problem to be solved by this utility model embodiment is to provide a scraping film assembly to solve the problem that the sliding scraping film assembly in the prior art requires a relatively large force.
[0006] In a first aspect, this utility model provides a film scraping assembly, comprising: a slider for slidingly connecting with the body of a film application box; a first flexible film scraping block disposed on the slider, the bottom of the first flexible film scraping block having a pressure-applying surface for applying pressure to the planar portion of a curved screen; and a second flexible film scraping block disposed on the slider and located on the back side of the first flexible film scraping block, the bottom of the second flexible film scraping block having a pressure-applying protrusion for applying pressure to the curved portion of the curved screen; wherein the thickness of the first flexible film scraping block is less than the thickness of the second flexible film scraping block.
[0007] Optionally, the first flexible scraping block and the second flexible scraping block are spaced apart.
[0008] Optionally, both the first flexible scraping block and the second flexible scraping block are detachably connected to the slider.
[0009] Optionally, the bottom of the slider is provided with a first slot and a second slot, the first slot and the second slot respectively cooperating with the first flexible scraping block and the second flexible scraping block, so that the first flexible scraping block and the second flexible scraping block are detachably connected to the slider.
[0010] Optionally, the thickness of the first flexible scraping block is greater than or equal to 2 mm and less than or equal to 3.5 mm, and the thickness of the second flexible scraping block is greater than or equal to 4 mm and less than or equal to 6 mm.
[0011] Optionally, the second flexible scraping block has two pressure protrusions spaced apart along the length of the pressure plane, and a connecting portion connecting the two pressure protrusions, the connecting portion being higher than the pressure plane.
[0012] Optionally, two second flexible scraping blocks are provided, and the two second flexible scraping blocks are spaced apart in the length direction of the pressure plane to form a clearance space between them to avoid the plane portion.
[0013] Secondly, this utility model embodiment also provides a film applicator box, which includes a box body and a film scraping assembly. The film scraping assembly is the film scraping assembly shown in the first aspect above, and the slider of the film scraping assembly is slidably connected to the box body.
[0014] Optionally, the slider is detachably connected to the housing.
[0015] Optionally, the side wall of the box body is provided with a sliding groove, the groove wall of the sliding groove is provided with a through groove connecting the sliding groove and the outside, and the slider is provided with a protrusion that cooperates with the sliding groove, the outline of the protrusion being smaller than the outline of the through groove.
[0016] Compared with the prior art, the beneficial effects of the film scraping assembly provided in this embodiment of the present invention are as follows: The film scraping assembly provided in this embodiment of the present invention includes a slider, a first flexible film scraping block, and a second flexible film scraping block. The slider is used to slide in connection with the body of the film application box. The first flexible film scraping block is disposed on the slider, and the bottom of the first flexible film scraping block has a pressure-applying surface, which is used to apply pressure to the flat part of the curved screen. The second flexible film scraping block is disposed on the slider and located on the back side of the first flexible film scraping block. The bottom of the second flexible film scraping block is provided with a pressure-applying protrusion, which is used to apply pressure to the flat part of the curved screen. The curved portion of the curved screen is pressurized; specifically, the thickness of the first flexible squeegee block is less than the thickness of the second flexible squeegee block. According to experiments, the curved portion has a greater force requirement, so the second flexible squeegee block needs to be thick enough to compress the curved portion. The flat portion has a smaller force requirement, so it does not need to be as thick as the second flexible squeegee block. In this embodiment of the invention, by making the first flexible squeegee block thinner than the second flexible squeegee block, it can not only achieve the film application effect of the squeegee assembly in the prior art, but also reduce the force used by the sliding squeegee assembly.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0032] This utility model embodiment provides a film scraping assembly 100, such as Figures 1-3 As shown, the film scraping assembly 100 includes a slider 110, a first flexible film scraping block 120, and a second flexible film scraping block 130. The slider 110 is slidably connected to the box body 200 of the film application box 1000. The first flexible film scraping block 120 is disposed on the slider 110, and the bottom of the first flexible film scraping block 120 has a pressure-applying surface 121, which is used to apply pressure to the flat portion of the curved screen. The second flexible film scraping block 130 is disposed on the slider 110 and is located on the back side of the first flexible film scraping block 120. The bottom of the second flexible film scraping block 130 is provided with a pressure-applying protrusion 131, which is used to apply pressure to the curved portion of the curved screen. The thickness of the first flexible film scraping block 120 is less than the thickness of the second flexible film scraping block 130.
[0033] Specifically, according to experiments, the curved part of the curved screen has a greater stress requirement, so the second flexible squeegee block 130 needs to be thick enough to compress the curved part. The flat part of the curved screen has a smaller stress requirement, so it does not need to be as thick as the second flexible squeegee block 130. In this embodiment of the invention, the first flexible squeegee block 120 is made thinner than the second flexible squeegee block 130. This not only achieves the film application effect of the squeegee assembly 100 in the prior art, but also reduces the force used by the sliding squeegee assembly 100.
[0034] refer to Figure 3 In a specific embodiment, the first flexible scraping block 120 and the second flexible scraping block 130 are arranged at intervals.
[0035] Specifically, the first flexible squeegee 120 is flexible, so during the sliding of the slider 110, the first flexible squeegee 120 will deform due to the reverse force provided by the flat part of the curved screen. If the second flexible squeegee 130 is placed close to the first flexible squeegee 120, the first flexible squeegee 120 will press against the second flexible squeegee 130, causing the second flexible squeegee 130 to deform. The deformation of the second flexible squeegee 130 will affect the film application effect on the curved part of the curved screen. To solve this technical problem, in this embodiment, the first flexible squeegee 120 and the second flexible squeegee 130 are spaced apart, thus providing deformation space for the first flexible squeegee 120. Even if the first flexible squeegee 120 deforms, it will not press against the second flexible squeegee 130.
[0036] refer to Figure 3 , Figure 4 In a specific embodiment, both the first flexible scraping block 120 and the second flexible scraping block 130 are detachably connected to the slider 110.
[0037] By implementing this embodiment, the film application assembly 100 can be adapted to different models of film application equipment by replacing the first flexible film application block 120 and the second flexible film application block 130, which helps to reduce production costs. Furthermore, if the first flexible film application block 120 or the second flexible film application block 130 is damaged, only the first flexible film application block 120 or the second flexible film application block 130 needs to be replaced, without replacing the entire film application box 1000.
[0038] refer to Figure 3 , Figure 4 In a specific embodiment, the bottom of the slider 110 is provided with a first slot 111 and a second slot 112. The first slot 111 and the second slot 112 respectively cooperate with the first flexible scraping block 120 and the second flexible scraping block 130 so that the first flexible scraping block 120 and the second flexible scraping block 130 are detachably connected to the slider 110.
[0039] Specifically, by implementing this embodiment, the disassembly and installation of the first flexible scraping block 120 and the second flexible scraping block 130 are facilitated. To install the first flexible scraping block 120, simply insert it into the first slot 111; to remove it, simply pull it out of the first slot 111. Similarly, to install the second flexible scraping block 130, simply insert it into the second slot 112; to remove it, simply pull it out of the second slot 112.
[0040] refer to Figure 3In some embodiments, the thickness of the first flexible squeegee block 120 is greater than or equal to 2 mm and less than or equal to 3.5 mm, and the thickness of the second flexible squeegee block 130 is greater than or equal to 4 mm and less than or equal to 6 mm. This configuration not only ensures the film application effect but also reduces the force required by the sliding squeegee assembly 100.
[0041] refer to Figure 3 In some embodiments, the second flexible scraping block 130 is provided with two pressure protrusions 131 spaced apart along the length of the pressure plane 121, and a connecting portion 132 connecting the two pressure protrusions 131, the connecting portion 132 being higher than the pressure plane 121. This arrangement allows the second flexible scraping block 130 to avoid pressing the curved portion of the curved screen, thus preventing an increase in the force used by the sliding scraping assembly 100.
[0042] Optionally, two second flexible squeegee blocks 130 are provided, and the two second flexible squeegee blocks 130 are spaced apart in the length direction of the pressure plane 121 to form a clearance space between them to avoid the planar portion. With this arrangement, when the second flexible squeegee blocks 130 are used to apply pressure to the curved portion of the curved screen, the planar portion of the curved screen is avoided, so as to avoid increasing the force used by the sliding squeegee assembly 100.
[0043] refer to Figure 3 In some embodiments, the first flexible film scraping block 120 and the second flexible film scraping block 130 are both made of EVA foam. EVA foam is moderately soft and elastic, which helps to ensure the film application effect. In addition, EVA foam can be repeatedly recycled and has less environmental harm.
[0044] This utility model embodiment also provides a film application box 1000, such as Figures 1-3 As shown, the film application box 1000 includes a box body 200 and a film scraping assembly 100. The box body 200 is used to fix the device to be applied to the film and the film application. The film scraping assembly 100 is the film scraping assembly 100 shown in the above embodiment. The slider 110 of the film scraping assembly 100 is slidably connected to the box body 200.
[0045] Specifically, the film scraping assembly 100 includes a slider 110, a first flexible film scraping block 120, and a second flexible film scraping block 130. The slider 110 is slidably connected to the box body 200 of the film application box 1000. The first flexible film scraping block 120 is disposed on the slider 110, and the bottom of the first flexible film scraping block 120 has a pressure-applying surface 121 for applying pressure to the flat portion of the curved screen. The second flexible film scraping block 130 is disposed on the slider 110 and located on the back side of the first flexible film scraping block 120. The bottom of the second flexible film scraping block 130 has a pressure-applying protrusion 131 for applying pressure to the curved portion of the curved screen. The thickness of the first flexible film scraping block 120 is less than the thickness of the second flexible film scraping block 130.
[0046] According to experiments, the curved part of the curved screen has a relatively large force requirement, so the second flexible squeegee block 130 needs to be thick enough to compress the curved part. The flat part of the curved screen has a relatively small force requirement, so it does not need to be as thick as the second flexible squeegee block 130. In this embodiment of the invention, the first flexible squeegee block 120 is made thinner than the second flexible squeegee block 130. This not only achieves the film application effect of the squeegee assembly 100 in the prior art, but also reduces the force used by the sliding squeegee assembly 100.
[0047] refer to Figures 1-6 In a specific embodiment, the slider 110 is detachably connected to the box 200.
[0048] Specifically, in the existing film applicator box 1000, the slider 110 cannot be detached from the box body 200, resulting in a relatively long box body 200. Because the box body 200 has an applicator area for placing the film, the slider 110 must slide completely out of the applicator area to fit the film onto the box body 200. Therefore, the box body 200 needs a region adjacent to the applicator area for the slider 110 to slide completely out, which also leads to a relatively long box body 200. In this embodiment, however, the slider 110 is detachably connected to the box body 200. This means that the slider 110 can be detached only when the film needs to be applied, and reattached after application. Therefore, the box body 200 in this embodiment can be designed to be shorter, effectively reducing the transportation and storage costs of the film applicator box 1000.
[0049] like Figure 5 , Figure 6 As shown, in a specific embodiment, the side wall of the box 200 is provided with a sliding groove 210, the groove wall of the sliding groove 210 is provided with a through groove 220 connecting the sliding groove 210 and the outside, and the slider 110 is provided with a protrusion 113 that cooperates with the sliding groove 210. The outline of the protrusion 113 is smaller than the outline of the through groove 220.
[0050] Specifically, since the outline of the protrusion 113 is smaller than the outline of the through groove 220, when the slider 110 moves to the point where the protrusion 113 aligns with the through groove 220, the protrusion 113 can disengage from the slide groove 210 via the through groove 220, thereby allowing the slider 110 to be detached from the housing 200. When the slider 110 needs to be installed, simply align the protrusion 113 with the through groove 220 and place the protrusion 113 into the slide groove 210 using the through groove 220, which is very convenient.
[0051] refer to Figure 1 , Figure 2 , Figure 7 In some embodiments, the film application box 1000 further includes a cover 300 rotatably connected to the box body 200. The cover 300 has a first guide structure 310 on the side facing the box body 200, and the slider 110 has a second guide structure 114 on the side facing the cover 300 that cooperates with the first guide structure 310. The cooperation of the first guide structure 310 and the second guide structure 114 can provide guidance for the slider 110 to further improve the film application effect.
[0052] refer to Figure 1 , Figure 2 , Figure 7 In a specific embodiment, the first guide structure 310 is one of a convex strip and a groove, and the second guide structure 114 is the other of a convex strip and a groove.
[0053] refer to Figure 1 , Figure 2 , Figure 7 In some embodiments, two first guide structures 310 are provided, and two corresponding second guide structures 114 are provided, which can further improve the guiding effect and thus further improve the film application effect.
[0054] refer to Figure 5 In a specific embodiment, the housing 200 includes a first support platform 230 and a second support platform 240. The first support platform 230 and the second support platform 240 are spaced apart along the length of the slide groove 210 to support the film on opposite sides of the film. The first support platform 230 is lower than the second support platform 240, so that after the film is installed, it is tilted, effectively preventing the middle part of the film from sagging and sticking to the mobile terminal before the film scraper assembly 100 is used. When using the film scraper assembly 100, it slides gradually from the side closer to the device to be covered to the other side, which helps reduce air bubbles generated during film application, resulting in a superior user experience.
[0055] refer to Figure 1 , Figure 7In some embodiments, a locking block 320 is provided on the outer side wall of the cover 300. The locking block 320 is used to engage with the slider 110 when all the sliders 110 move to the alignment of the protrusion 113 and the through groove 220. In this way, the slider 110 can be removed from the box 200 simply by rotating the cover 300, which is very convenient.
