Description

Technical Field

[0001] This application relates to the field of screen protector technology for electronic devices, and more particularly to a screen protector application device. Background Technology

[0002] Traditional screen protector applicators typically come with an applicator housing and two protective films. This is to allow users to use the spare film if they accidentally fail to apply the screen protector. However, the applicator housing usually only holds one protective film. When the applicator is sold, the housing and one protective film are already assembled, while the other protective film is sold loose. If a user needs to apply the second protective film, they must manually install it into the housing, which is rather cumbersome. Utility Model Content

[0003] Therefore, it is necessary to provide a film application device that is highly convenient to apply and easy to package and store.

[0004] A film application device, comprising:

[0005] A first film applicator includes a first film-applying shell and a first protective film. The first film-applying shell has an outer surface and an inner surface that are disposed opposite each other in the thickness direction. A first film-applying cavity is provided on one side of the first film-applying shell where its inner surface is located, and the first protective film is disposed in the first film-applying cavity.

[0006] The second film applicator includes a second film shell and a second protective film. The second film shell has an outer surface and an inner surface that are oppositely disposed in the thickness direction. The second film shell has a second film cavity on one side of its inner surface. The second protective film is disposed in the second film cavity. The inner surfaces of the first film shell and the second film shell are disposed facing each other. The first film shell and the second film shell are stacked sequentially along the thickness direction of the film applicator, and the first film shell and the second film shell partially overlap in the thickness direction of the film applicator. The sum of the thickness of the first film shell and the thickness of the second film shell is less than the thickness of the film applicator formed by stacking the two film applicators.

[0007] In one embodiment, both the first film-applying shell and the second film-applying shell are provided with a protruding edge and a groove. The protruding edge of the first film-applying shell can be fitted with the groove of the second film-applying shell, and the protruding edge of the second film-applying shell can be fitted with the groove of the first film-applying shell, thereby achieving partial overlap between the first film-applying shell and the second film-applying shell in the thickness direction of the film-applying device.

[0008] In one embodiment, both the first film shell and the second film shell are provided with a plurality of the convex edges and a plurality of the grooves, and the convex edges and the grooves are alternately arranged.

[0009] In one embodiment, both the first applicator and the second applicator have a first end and a second end that are disposed opposite to each other along their length extension direction. The first applicator and the second applicator have the same structure. The first end of the first applicator and the second end of the second applicator are opposite to each other in the thickness direction of the applicator. The second end of the first applicator and the first end of the second applicator are opposite to each other in the thickness direction of the applicator.

[0010] In one embodiment, both the first protective film and the second protective film include a release film, a positioning film, and a film body for attaching to the screen of an electronic device, the film body being disposed between the release film and the positioning film; the release film of the first protective film extends out of the first end of the first film shell, and the release film of the second protective film extends out of the first end of the second film shell.

[0011] In one embodiment, the release film includes a tear-off member and a release member stacked together. The tear-off member is disposed on the outermost layer, and one end of the tear-off member in the length direction is connected to the release member. The side of the release member away from the tear-off member covers the film body. The two tear-off members extend out of the first end of the first film shell and the first end of the second film shell, respectively.

[0012] In one embodiment, the first end of the first film shell is provided with a pull-out opening communicating with the first film cavity, the first end of the second film shell is provided with a pull-out opening communicating with the second film cavity, one end of the release film of the first protective film passes through the pull-out opening of the first film shell, and one end of the release film of the second protective film passes through the pull-out opening of the second film shell.

[0013] In one embodiment, both the first and second screen protector applicators further include a limiting connection portion. The limiting connection portion of the first screen protector applicator is disposed on the first screen protector housing and located outside the first screen protector cavity. The limiting connection portion of the first screen protector applicator is used to connect with the positioning film of the first protective film so that the first protective film faces the screen of the electronic device. The limiting connection portion of the second screen protector applicator is disposed on the second screen protector housing and located outside the second screen protector cavity. The limiting connection portion of the second screen protector applicator is used to connect with the positioning film of the first and second protective films so that the second protective film faces the screen of the electronic device.

[0014] In one embodiment, both the first applicator and the second applicator further include a pad, wherein the pad of the first applicator is disposed on the side of the first applicator shell facing the first applicator cavity, and the pad of the second applicator is disposed on the side of the second applicator shell facing the second applicator cavity.

[0015] In one embodiment, the pads of the first and second applicators are elastic or non-elastic pads; and / or

[0016] The pad of the first applicator is disposed in the middle of the first applicator cavity, and the pad of the first applicator extends along the length direction of the first applicator cavity; the pad of the second applicator is disposed in the middle of the second applicator cavity, and the pad of the second applicator extends along the length direction of the second applicator cavity; and / or

[0017] The pad of the first applicator is fixed to the first applicator shell by adhesive, and the pad of the second applicator is fixed to the second applicator shell by adhesive; or, the pad of the first applicator and the first applicator shell are integrally injection molded, and the pad of the second applicator shell and the second applicator shell are integrally injection molded.

[0018] This utility model has at least the following beneficial effects:

[0019] The aforementioned screen protector application device, by coupling two pre-assembled screen protector applicators, allows for easy application when one applicator fails to apply the screen protector due to user error. The user can then directly use the other applicator to apply the screen protector to the electronic device without needing to manually assemble the protective film and screen protector housing beforehand. This significantly improves the convenience of the application process. Furthermore, since the first and second screen protector housings partially overlap in the thickness direction of the device, and the sum of their thicknesses is less than the thickness of the device formed by stacking the two applicators, the overall size of the device can be effectively reduced, facilitating packaging and storage.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a film applicator 10, which includes a first applicator 100 and a second applicator 200. The first applicator 100 includes a first applicator shell 110 and a first protective film 120. The first applicator shell 110 has an outer surface and an inner surface that are disposed opposite to each other in the thickness direction. The first applicator shell 110 has a first applicator cavity 111 on one side of its inner surface, and the first protective film 120 is disposed in the first applicator cavity 111. The second applicator 200 includes a second applicator shell 210 and a second protective film 220. The second applicator shell 210 has an outer surface and an inner surface that are disposed opposite to each other in the thickness direction. The second applicator shell 200 has a first applicator cavity 111 on one side of its inner surface, and the first protective film 120 is disposed in the first applicator cavity 111. A second film-applying cavity 211 is provided on one side of the inner surface. The inner surfaces of the first film-applying shell 110 and the second film-applying shell 210 are arranged facing each other. The second protective film 220 is disposed in the second film-applying cavity 211. The first film-applying shell 110 and the second film-applying shell 210 are stacked sequentially along the thickness direction of the film-applying device 10, and the first film-applying shell 110 and the second film-applying shell 210 partially overlap in the thickness direction of the film-applying device 10. The sum of the thickness of the first film-applying shell 110 and the thickness of the second film-applying shell 210 is less than the thickness of the film-applying device 10 formed by the two film applicators stacked together. It should be noted that the thickness of the film-applying shell refers to the extreme distance between the two ends in the thickness direction of the film-applying shell.

[0031] The aforementioned screen protector device 10, by coupling two pre-assembled screen protectors, allows the user to directly apply the screen protector to the electronic device's screen if the application fails due to user error while using one of the pre-assembled screen protectors. This eliminates the need for manual assembly of the protective film and the screen protector housing beforehand, making the application process more convenient. Furthermore, since the first screen protector housing 110 and the second screen protector housing 210 partially overlap in the thickness direction of the screen protector device 10, and the sum of the thicknesses of the first screen protector housing 110 and the second screen protector housing 210 is less than the thickness of the screen protector device 10 formed by the two screen protectors stacked together, the overall volume of the screen protector device 10 can be effectively reduced, facilitating its packaging and storage.

[0032] like Figure 2 As shown, in one embodiment, both the first film-applying shell 110 and the second film-applying shell 210 are provided with a protruding edge 112 and a groove 113. The protruding edge 112 of the first film-applying shell 110 can be fitted with the groove 113 of the second film-applying shell 210, and the protruding edge 112 of the second film-applying shell 210 can be fitted with the groove 113 of the first film-applying shell 110, thereby achieving partial overlap of the first film-applying shell 110 and the second film-applying shell 210 in the thickness direction of the film-applying device 10.

[0033] Specifically, both the first film-coating shell 110 and the second film-coating shell 210 are provided with multiple protruding edges 112 and multiple grooves 113, and the protruding edges 112 and grooves 113 are alternately arranged. Specifically, in this embodiment, the first film-coating shell 110 has multiple protruding edges 112 and multiple grooves 113 on opposite sides in the width direction, and the second film-coating shell 210 has multiple protruding edges 112 and multiple grooves 113 on opposite sides in the width direction.

[0034] like Figure 1 As shown, specifically in this embodiment, both the first film-applying shell 110 and the second film-applying shell 210 have a first end and a second end that are arranged opposite to each other along their length extension direction. The structures of the first film applicator 100 and the second film applicator 200 are completely identical. The first end 101 of the first film applicator 100 and the second end 202 of the second film applicator 200 are opposite to each other in the thickness direction of the film-applying device 10, and the second end 102 of the first film applicator 100 and the first end 201 of the second film applicator 200 are opposite to each other in the thickness direction of the film-applying device 10. That is, the first film applicator 100 and the second film applicator 200 are stacked together in opposite directions in the thickness direction of the film-applying device 10.

[0035] like Figure 3As shown, in one embodiment, both the first protective film 120 and the second protective film 220 include a release film 121, a positioning film 123, and a film body 122 for attaching to the screen of an electronic device. The film body 122 is disposed between the release film 121 and the positioning film 123. The release film 121 of the first protective film 120 extends out of the first end of the first film cover 110, and the release film 121 of the second protective film 220 extends out of the first end of the second film cover 210.

[0036] Taking the working principle of the first screen protector 100 as an example, when the first screen protector 100 is placed horizontally and the screen protector is applied, the first protective film 120 is located in the first screen protector cavity 111, and the electronic device is located above the first protective film 120. The release film 121, the film body 122, and the positioning film 123 in the first protective film 120 are arranged sequentially from top to bottom. During the application process, the positioning film 123 at the bottom is used to connect with and limit the first screen protector shell 110. By peeling the release film 121 off the surface of the film body 122, when the release film 121 is separated from the film body 122, dust is drawn in contact with the screen of the electronic device, so that the middle film body 122 is facing the screen of the electronic device. When the film body 122 is adhered to the screen of the electronic device, the application is completed. Then the positioning film 123 is separated from the film body 122, so that the film body 122 stably covers the surface of the screen of the electronic device, thus protecting the screen of the electronic device. The electronic device in this embodiment can be an electronic terminal product such as a tablet computer, mobile phone, or e-reader.

[0037] like Figure 3 As shown, the release film 121 further includes a tear-off member 1211 and a release member 1212 stacked together. The tear-off member 1211 is disposed on the outermost layer. One end of the tear-off member 1211 in the length direction is connected to the release member 1212. The side of the release member 1212 away from the tear-off member 1211 covers the film body 122. The two tear-off members 1211 extend out of the first end of the first film shell 110 and the first end of the second film shell 210, respectively.

[0038] Specifically, taking the first protective film 120 as an example, the user pulls the tearing piece 1211 outward, causing the tearing piece 1211 to drive the release piece 1212 at the other end to fold upward and in the direction of pulling, and to separate from the film body 122. The folded release piece 1212 sweeps across the screen of the electronic device above, thereby achieving dust removal from the screen of the electronic device.

[0039] In one embodiment, the first end of the first film shell 110 is provided with a pull-out opening 114 communicating with the first film cavity 111, and the first end of the second film shell 210 is provided with a pull-out opening 114 communicating with the second film cavity 211. One end of the release film 121 of the first protective film 120 passes through the pull-out opening 114 of the first film shell 110, and one end of the release film 121 of the second protective film 220 passes through the pull-out opening 114 of the second film shell 210. Specifically, the pull-out opening 114 of the first film shell 110 is located at one end of the length direction of the first film shell 110 and extends along the width direction of the first film shell 110. The pull-out opening 114 of the second film shell 210 is located at one end of the length direction of the second film shell 210 and extends along the width direction of the second film shell 210.

[0040] Taking the first film applicator 100 as an example, when it is necessary to separate the release film 121 from the film body 122, by pulling the pull end of the release film 121 (i.e., the end of the release film 121 exposed in the pull opening 114), the release film 121 is flipped from the other end opposite to the pull end and begins to detach from the film body 122 until the release film 121 is pulled out from the pull opening 114, so that the film body 122 and the screen of the electronic device are adsorbed and bonded. Since the side of the release film 121 that is bonded to the film body 122 has an electrostatic effect, the release film 121 can adsorb the dust on the screen of the electronic device and carry the dust out from the pull opening 114 while being pulled out.

[0041] like Figure 3 As shown, both the first screen protector 100 and the second screen protector 200 further include a limiting connection portion 130. The limiting connection portion 130 of the first screen protector 100 is disposed on the first screen protector housing 110 and located outside the first screen protector cavity 111. The limiting connection portion 130 of the first screen protector 100 is used to connect with the positioning film 123 of the first protective film 120 so that the first protective film 120 faces the screen of the electronic device. The limiting connection portion 130 of the second screen protector 200 is disposed on the second screen protector housing 210 and located outside the second screen protector cavity 211. The limiting connection portion 130 of the second screen protector 200 is used to connect with the positioning film 123 of the second protective film 220 so that the second protective film 220 faces the screen of the electronic device.

[0042] Specifically, the positioning film 123 of both the first protective film 120 and the second protective film 220 includes a positioning body 1231 and a protruding section 1232 connected to the positioning body 1231. The film body 122 is disposed on the positioning body 1231, and the protruding section 1232 protrudes from the positioning body 1231 along its length. The positioning body 1231 of the first protective film 120 is located inside the first film-applying cavity 111, and the protruding section 1232 of the first protective film 120 extends outside the first film-applying cavity 111. The positioning body 1231 of the second protective film 220 is located inside the second film-applying cavity 211. The protruding section 1232 of the second protective film 220 extends to the outside of the second film application cavity 211. Both the first protective film 120 and the protruding section 1232 of the second protective film 220 are provided with limiting holes 1233. The positioning film 123 of the first protective film 120 is connected to the limiting connection part 130 of the first film applicator 100 through the limiting hole 1233. By connecting the positioning film 123 of the first protective film 120 with the limiting connection part 130 of the first film applicator 100, the length direction of the first protective film 120 can be limited, so that the first protective film 120 is not easy to move in the length direction. Similarly, the positioning film 123 of the second protective film 220 is connected to the limiting connection part 130 of the second film applicator 200 through its limiting hole 1233. By connecting the positioning film 123 of the second protective film 220 to the limiting connection part 130 of the second film applicator 200, the length direction of the second protective film 220 can be limited, thereby making it difficult for the second protective film 220 to move in the length direction.

[0043] Furthermore, to improve the positioning effect of the first protective film 120 and the second protective film 220, both ends of the first film-applying shell 110 and the second film-applying shell 210 in the length direction are provided with limiting connecting portions 130. The positioning film 123 of both the first protective film 120 and the second protective film 220 includes two protruding segments 1232. The two protruding segments 1232 of the first protective film 120 are respectively disposed at both ends of the positioning body 1231 of the first protective film 120 in the length direction, and are positioned by the two limiting connecting portions 130 of the first film applicator 100. The two protruding sections 1232 of the first protective film 120 are respectively inserted into the limiting holes 1233 of the two protruding sections 1232 of the second protective film 220 to limit the length of the first protective film 120. The two protruding sections 1232 of the second protective film 220 are respectively disposed at both ends of the positioning body 1231 of the second protective film 220 in the length direction. The two limiting connecting parts 130 of the second film applicator 200 are respectively inserted into the limiting holes 1233 of the two protruding sections 1232 of the second protective film 220 to limit the length of the second protective film 220.

[0044] like Figure 3 and Figure 4As shown, further, to improve the positioning effect of the first protective film 120 and the second protective film 220, the limiting connection portion 130 of the first film applicator 100 includes a plurality of limiting members 132 spaced apart along the width direction of the first film shell 110. A plurality of limiting holes 1233 are spaced apart on the protruding section 1232 of the first protective film 120. The plurality of limiting members 132 of the first film applicator 100 are respectively inserted into and cooperate with the plurality of limiting holes 1233 on the protruding section 1232 of the first protective film 120 to achieve the desired positioning effect. The first protective film 120 is limited in the length direction. The limiting connection part 130 of the second film applicator 200 includes a plurality of limiting members 132 spaced apart along the width direction of the second film shell 210. A plurality of limiting holes 1233 are spaced apart on the protruding section 1232 of the second protective film 220. The plurality of limiting members 132 of the second film applicator 200 are respectively inserted and cooperated with the plurality of limiting holes 1233 on the protruding section 1232 of the second protective film 220 to limit the length direction of the second protective film 220.

[0045] like Figure 3 and Figure 4 As shown, both the first applicator 100 and the second applicator 200 further include a pad 140. The pad 140 of the first applicator 100 is disposed on the side of the first applicator shell 110 facing the first applicator cavity 111 (i.e., the inner surface of the first applicator shell 110), and the pad 140 of the second applicator 200 is disposed on the side of the second applicator shell 210 facing the second applicator cavity 211 (i.e., the inner surface of the second applicator shell 210).

[0046] Taking the first screen protector 100 as an example, the pad 140 of the first screen protector 100 serves two purposes. First, it ensures that the first protective film 120 and the screen of the electronic device are placed more evenly into the first screen protector cavity 111, preventing unevenness that could affect the screen protector application. Second, without the pad 140, if the first protective film 120 is placed directly into the first screen protector cavity 111, the edge of the release liner 121 may scrape against the inner wall of the first screen protector cavity 111, causing jamming. The pad 140 makes the release liner 121 easier to pull out, preventing jamming. Furthermore, the pad 140 facilitates smoother pulling of the release liner 121 during the process of pulling out the release liner 121. Both the first protective film 120 and the screen of the electronic device have a certain amount of movable space, providing sufficient space for the release film 121 to be pulled out, making it easier to pull out the release film 121. On the other hand, the pad 140 is set so that during the process of pulling out the release film 121, by pressing the end of the electronic device away from the pull-out opening 114, there is a height difference between the two ends of the electronic device, that is, the electronic device has a certain angle. This makes it easier to adjust the angle when pulling out the release film 121 while the first protective film 120 is gradually adsorbed and attached to the screen of the electronic device, so as to more fully remove air bubbles and make the adhesion effect between the first protective film 120 and the screen of the electronic device better.

[0047] In one embodiment, the pads 140 of both the first applicator 100 and the second applicator 200 are rectangular, and one or more pads 140 are provided in both the first applicator 100 and the second applicator 200. Specifically, the pad 140 of the first applicator 100 is located in the middle of the first applicator cavity 111 and extends along the length direction of the first applicator cavity 111; the pad 140 of the second applicator 200 is located in the middle of the second applicator cavity 211 and extends along the length direction of the second applicator cavity 211. Further, the pads 140 of the first applicator 100 and the second applicator 200 can be elastic pads or non-elastic pads; for example, the pad 140 can be a foam pad. In one embodiment, the pad 140 of the first applicator 100 can be fixed to the first applicator housing 110 by adhesive, and the pad 140 of the second applicator 200 can be fixed to the second applicator housing 210 by adhesive. It is understood that in other embodiments, the pad 140 of the first applicator 100 can be integrally injection molded with the first applicator housing 110, and the pad 140 of the second applicator 200 can be integrally injection molded with the second applicator housing 210.

[0048] like Figure 3 and Figure 4As shown, further, both the first film-applying shell 110 and the second film-applying shell 210 include a back plate 115 and a baffle 116. The back plate 115 can be a flat plate, generally square in shape. The baffle 116 surrounds the inner surface of the back plate 115. The baffle 116 of the first film-applying shell 110 surrounds the inner surface of the back plate 115 of the first film-applying shell 110 and forms a first film-applying cavity 111. The baffle 116 of the second film-applying shell 210 surrounds the inner surface of the back plate 115 of the second film-applying shell 210 and forms a second film-applying cavity 211. The limiting connection part 130 of the first film applicator 100 is disposed on the inner surface of the back plate 115 of the first film-applying shell 110. The limiting connection part 130 of the second film applicator 200 is disposed on the inner surface of the back plate 115 of the first film-applying shell 110. On the inner surface of the back plate 115 of the second film-applying shell 210, protruding edges 112 and grooves 113 are provided on opposite sides of the baffles 116 of the first film-applying shell 110 and the second film-applying shell 210 in the width direction. A pull-out opening 114 is provided at one end of the baffles 116 of the first film-applying shell 110 and the second film-applying shell 210 in the length direction. The pad 140 of the first film applicator 100 is provided on the inner surface of the back plate 115 of the first film-applying shell 110 and extends along the length direction of the back plate 115 of the first film-applying shell 110. The pad 140 of the second film applicator 200 is provided on the inner surface of the back plate 115 of the second film-applying shell 210 and extends along the length direction of the back plate 115 of the second film-applying shell 210. The first film-applying shell 110 and the second film-applying shell 210 are both spaced apart at one end of their flanges 116 along their length direction, forming a side opening 117. When the first protective film 120 is placed in the first film-applying cavity 111, the protruding section 1232 of the positioning film 123 of the first protective film 120 protrudes from the side opening 117 of the first film-applying shell 110 and connects to the limiting connection portion 130 of the first film applicator 100. When the second protective film 220 is placed in the second film-applying cavity 211, the protruding section 1232 of the positioning film 123 of the second protective film 220 protrudes from the side opening 117 of the second film-applying shell 210 and connects to the limiting connection portion 130 of the second film applicator 200.

[0049] The working principle of the first screen protector 100 of this utility model is as follows: The assembled first protective film 120 is placed in the first film application cavity 111, and the positioning film 123 of the first protective film 120 is connected to the limiting connection part 130, so that the screen of the electronic device is directly facing the film body 122 of the first protective film 120. The user presses down on the end of the electronic device away from the pull-out opening 114. At this time, due to the compression of the pad 140, the pressed end of the electronic device slightly descends, causing both the screen of the electronic device and the film body 122 to be at a certain angle. With the other hand, the release film 121 is pulled out from the pull-out port 114. When the release film 121 is separated from the film body 122, it comes into contact with the screen of the electronic device to collect dust. After the release film 121 is completely removed, the film body 122 in the middle is aligned with the screen of the electronic device. After the film body 122 is adhered to the screen of the electronic device, the film application is completed. Then, the positioning film 123 is separated from the film body 122, so that the film body 122 is stably covered on the surface of the screen of the electronic device, thus protecting the screen of the electronic device.

[0050] It should be noted that, in this embodiment, since the structure of the second applicator 200 is exactly the same as that of the first applicator 100, the operating principle of the second applicator 200 will not be described again.

[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
