[0039] Example 1

[0040] like Figure 1 、 Figure 3 As shown, this embodiment proposes a screen film applicator with an elastic structure, which is used to apply film to the screen of a mobile terminal to be applied with a film. The mobile terminal in this embodiment can be various electronic products, such as mobile phones 10, tablet computers, e-books, smart watches and other electronic devices. To facilitate the structural description of this embodiment, the mobile phone 10 is taken as an example for explanation. The long side direction of the mobile phone 10 is the length direction (front and back direction), the short side direction is the width direction (left and right direction), and the thickness direction is the up and down direction. The length direction, width direction and up and down direction in the following text are all based on this for structural description. This screen film applicator with an elastic structure is used to adhere the membrane part of the protective film 20 to the screen of the mobile phone 10, as shown Figure 5 As shown, the protective film 20 can take various forms. For example, one form mainly includes: a film layer 23, a positioning release layer 21, and a tear-off release layer 24. The film layer 23 (the film that is actually attached to the screen surface) is used to be attached to the surface of the mobile phone 10 to protect the screen of the mobile phone 10; the positioning release layer 21 is detachably arranged on one side of the film layer 23, and the positioning release layer 21 is used to connect to the screen film applicator with an elastic structure. The tear-off release layer 24 is arranged on the side of the film layer 23 away from the positioning release layer 21 and facing the mobile phone 10. During use, the positioning release layer 21 and the tear-off release layer 24 are both pulled away from the film layer 23, leaving only the film layer 23 adhered to the screen surface of the mobile phone 10.

[0041] like Figure 1 、 Figure 3 、 Figure 5 As shown, the screen film applicator with an elastic structure in this embodiment mainly includes a shell 100. The shell 100 can be set as a square structure, and the shell 100 is placed flat when in use. An accommodating inner cavity 110 is provided in the shell 100. In the specific structure, the bottom of the shell 100 is a base plate, and ribs are provided around the base plate to form an accommodating inner cavity 110. The accommodating inner cavity 110 is open upward and is used to accommodate and limit the protective film 20 and the mobile terminal to be applied with the film. The protective film 20 is located below and the mobile terminal is located above the protective film 20. A pull-out end 120 is provided on one side of the length direction of the shell 100, and the pull-out end 120 is used to pull out the tear-off layer 24 of the protective film 20. An elastic structural part 200 is integrally formed on the shell 100. The elastic structural part 200 can be arranged on a side of the shell 100 close to the pull-out end 120 in the length direction, or on a side away from the pull-out end 120 in the length direction. The elastic structural part 200 can be arranged in the accommodating inner cavity 110 and is used to apply elastic force toward the accommodating inner cavity 110 to squeeze the protective film 20.

[0042] The screen film applicator of this embodiment provides a housing 100 with a receiving cavity 110. After the protective film 20 is placed in the receiving cavity 110, the tear-off layer 24 of the protective film 20 is extended from the pull-out end 120 at one end in the longitudinal direction. The mobile terminal is then placed in the receiving cavity 110 and positioned so that the mobile terminal screen and the protective film 20 are aligned. After the tear-off layer 24 of the protective film 20 is removed, the adhesive layer 23 of the protective film 20 is exposed and faces the mobile terminal screen. Because the housing 100 is integrally formed with an elastic structural member 200, the elastic structural member 200 applies an elastic force toward the receiving cavity 110, squeezing the protective film 20. This presses the exposed adhesive layer 23 onto the mobile terminal screen. In this application, the elastic structural member 200 is integrally formed with the housing 100, making the structure simpler and more practical. It does not require an additional step of bonding sponges, foam, or rubber pads, thus optimizing the production process and reducing production costs.

[0043] like Figure 1 、 Figure 3 、 Figure 4 As shown, the internal accommodating cavity 110 of this embodiment specifically includes: a film retaining cavity 113 located below and a terminal retaining cavity 112 located above. The terminal retaining cavity 112 is open on the side facing away from the elastic structural member 200. The terminal retaining cavity 112 is used to accommodate and retain the mobile terminal. The film retaining cavity 113 is located on the side of the terminal retaining cavity 112 facing the elastic structural member 200. In the specific structure, a limiting step 111 is provided on the inner wall of the retaining edge, and the upper surface of the limiting step 111 is spaced a certain distance from the bottom plate of the shell 100. The area enclosed below the limiting step 111 matches the protective film 20, so that the protective film 20 can be accommodated, and the area enclosed above the limiting step 111 matches the mobile terminal, so that the mobile terminal is limited by the upper surface of the limiting step 111, so that the screen of the mobile terminal is spaced a predetermined distance from the protective film 20 below, which facilitates the pulling out of the tear-off layer 24 of the protective film 20. It can be bent in the space to separate from the protective film 20, and the bent tear-off layer 24 rubs against the surface of the mobile terminal to take away the dust on the screen surface.

[0044] like Figure 1 、 Figure 3 、 Figure 4As shown, a film limiting component 130 is integrally formed on the shell 100, and the film limiting component 130 is located at the end of the film limiting cavity 113 away from the elastic structural component 200 in the length direction; for example, the pulling end 120 of this embodiment is located at the rear end of the shell 100, and the elastic structural component 200 is also located at the rear end of the shell 100, then the film limiting component 130 is located at the front end of the shell 100, and the film limiting component 130 is used to hook the positioning hole 22 on the positioning release layer 21 of the protective film 20, so that the protective film 20 is accommodated and limited in the film limiting cavity 113, and the tear release layer 24 of the protective film 20 passes through the pulling end 120. The film stopper 130 hooks onto the release layer 21 of the protective film 20, securing the protective film 20 in place. During the process of pulling away from the release layer 24, the protective film 20 remains securely attached to the housing 100 due to the hooking of the film stopper 130, ensuring a more stable connection for the protective film 20. The film stopper 130 typically comprises hooks arranged side by side and spaced apart along the width of the film applicator. This is a conventional structure used in film applicators and will not be described in detail.

[0045] like Figure 1 、 Figure 2 、 Figure 3 As shown, in this embodiment, the housing 100 is provided with a tear-off opening 114 on one side of the outer wall at the pull-out end 120. The tear-off opening 114 communicates with the film-applying limiting cavity 113, and the tear-off layer 24 of the protective film 20 passes through the tear-off opening 114. The tear-off opening 114 is provided on the rear side rib to facilitate the tear-off layer 24 passing through the tear-off opening 114, making it easier for the user to remove the tear-off layer 24 from the tear-off opening 114.

[0046] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the shell 100 of this embodiment is provided with an air-avoiding hole 140 on one side close to the pull-out end 120 in the length direction. In the specific structure, an air-avoiding hole 140 is provided at the rear end of the bottom plate of the shell 100. The air-avoiding hole 140 extends a certain length in the width direction. The width of the air-avoiding hole 140 can be nine-tenths of the width of the entire bottom plate, so that the elastic structural member 200 therein can be as long as possible in the width direction, thereby increasing the range of the extrusion force on the protective film 20. The elastic structural member 200 is located in the air-avoiding hole 140 and is connected to at least one inner wall of the air-avoiding hole 140. By providing the air-avoiding hole 140, the periphery of the elastic structural member 200 therein can be hollowed out, which is more conducive to the deformation of the elastic structural member 200 therein, enhances its elastic force, and achieves the effect of squeezing the protective film 20.

[0047] The elastic structural member 200 can be integrally connected to the inner wall of the air-avoiding hole 140 with one end in the left-right direction, or integrally connected to the inner wall of the air-avoiding hole 140 with one end in the front-back direction. If only one end is connected in the left-right direction, the elastic structural member 200 forms a cantilever beam structure, allowing the unconnected end to move and generate elasticity. This also achieves the effect of applying elastic force to the protective film 20 in the accommodating cavity 110.

[0048] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the elastic structural member 200 of this embodiment extends in the width direction, and its two ends are respectively connected to the two side walls in the width direction of the air avoidance hole 140. Therefore, by connecting the elastic structural member 200 to the left and right inner walls of the air avoidance hole 140, the elastic structural member 200 can generate an elastic force in the vertical direction within the air avoidance hole 140 as a whole, thereby increasing the extrusion length of the elastic structural member 200 in the width direction and applying a more uniform force across the entire extrusion range of the elastic structural member 200.

[0049] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the elastic structural member 200 of this embodiment specifically includes: a bending portion 210 and an extrusion portion 220 located at both ends in the width direction. The bending portions 210 at both ends are connected to the shell 100, and the two ends of the extrusion portion 220 are respectively connected to the bending portions 210 at both ends. The extrusion portion 220 has elasticity due to the bending portions 210, so as to squeeze the protective film 20 toward the accommodating inner cavity 110. The bending portions 210 at both ends in the width direction are easily deformed, so that the middle extrusion portion 220 generates elastic force. Since the bending portions 210 on both sides are symmetrically arranged, the elastic properties generated are the same, so that the force applied to the extrusion range in the width direction of the entire elastic structural member 200 is relatively uniform, achieving a better extrusion effect on the protective film 20.

[0050] like Figure 2 、 Figure 3As shown, the bending portion 210 of this embodiment specifically includes: a first bending section 211 and a second bending section 213. One end of the first bending section 211 is connected to the housing 100, and the other end is bent away from the accommodating inner cavity 110 to form a first U-shaped opening 212, with the opening of the first U-shaped opening 212 facing away from the accommodating inner cavity 110; one end of the second bending section 213 is connected to the first bending section 211, and the other end is bent toward the accommodating inner cavity 110 to form a second U-shaped opening 214, with the opening of the second U-shaped opening 214 facing the accommodating inner cavity 110; the two ends of the extrusion portion 220 are respectively connected to the second bending sections 213 at both ends. By adopting the form of connecting the first bending section 211 and the second bending section 213 at both ends in opposite directions, the bending portion 210 can be deformed to generate elasticity. In addition, the extrusion portion 220 protrudes toward the accommodating cavity 110 through the bending portion 210, so that the protective film 20 below can be pushed upward and pressed on the screen of the mobile phone 10 above.

[0051] It is easy to imagine that other structures of the bending portion 210 can also be used, such as arc-shaped bending, wave-shaped bending, etc. As long as a predetermined elastic force can be generated to squeeze the protective film 20, the technical problem can be solved.

[0052] like Figure 2 、 Figure 3 As shown, the extrusion portion 220 of this embodiment specifically includes: an extrusion plate 221 and an extrusion boss 222. The extrusion plate 221 is connected to the bent portion 210; the extrusion boss 222 is connected to the extrusion plate 221 and protrudes toward the side of the accommodating cavity 110. The extrusion boss 222 protrudes upward, so that the extrusion boss 222 can exert an upward extrusion force on the protective film 20, squeezing the protective film 20 onto the surface of the screen of the mobile phone 10 at the rear end.

[0053] like Figure 2 As shown, further, each side of the extrusion boss 222 of this embodiment is provided with a chamfer 223. The provision of the chamfer 223 forms a draft angle, thereby facilitating injection molding. Furthermore, the chamfer 223 can also reduce the surface area of the extrusion boss 222, making the center surface more convex and the extrusion force more concentrated.

[0054] Example 2

[0055] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, this embodiment provides a film-sticking kit, including the screen film sticking device with elastic structure and protective film 20 as described above. Figure 3 、 Figure 5As shown, the protective film 20 includes: a film layer 23, a positioning release layer 21, and a tear-off release layer 24. The positioning release layer 21 is connected to and limited on the housing 100. The tear-off release layer 24 is pulled out from the pull-out end 120 of the housing 100 so that the film layer 23 is aligned with the screen of the mobile terminal. The film layer 23 is used to be attached to the surface of the mobile phone 10 to protect the screen of the mobile phone 10; the positioning release layer 21 is detachably provided on one side of the film layer 23. The positioning release layer 21 is used to be connected to the film applicator. The front end of the positioning release layer 21 in the longitudinal direction is provided with a positioning hole 22. The positioning hole 22 is sleeved on the film stopper 130 on the housing 100 for positioning. The tear-off release layer 24 is provided on the side of the film layer 23 away from the positioning release layer 21 and facing the mobile phone 10.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
