DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0029] See also Figures 1 to 7 The film sticking assembly 1 provided by an embodiment of the utility model comprises a film sticking device 10 and a protective film 20. The film sticking device 10 is used to assist a user to stick the protective film 20 to the screen of an electronic device, and the type of the electronic device is not limited, such as a mobile phone, a tablet computer, etc. In the present application, the film sticking device 10 is used to assist a tablet computer in sticking a film, and the protective film 20 is a tempered film.

[0030] The film applicator 10 includes a first shell 11 and a second shell 13. The first shell 11 is movably covered on the second shell 13. When the first shell 11 is covered on the second shell 13, a positioning space 101 is formed between the first shell 11 and the second shell 13. The positioning space 101 can accommodate electronic devices, thereby forming a positioning effect for the electronic devices. The protective film 20 is located between the first shell 11 and the second shell 13. Since the film applicator 10 forms the positioning space 101 when the first shell 11 is covered on the second shell 13, when the electronic device is accommodated in the positioning space 101, the first shell 11 and the second shell 13 can prevent dust from entering the positioning space 101, so as to prevent dust from adhering to the screen of the electronic device or the protective film 20 to cause secondary pollution, thereby improving the film applicator quality.

[0031] The protective film 20 includes a positioning layer 21, a protective layer 23, a release layer 25 and a pull-out layer 27. The positioning layer 21 and the release layer 25 are respectively adhered to opposite sides of the protective layer 23. The positioning layer 21 is used to connect with the first shell 11 and / or the second shell 13, thereby forming a positioning effect on the positioning layer 21 so that it can be aligned with the screen of the electronic device. The release layer 25 is used to ensure the viscosity of the adhesive layer on the protective layer 23. One end of the pull-out layer 27 is connected to the release layer 25 and the other end extends to the outside of the first shell 11 and the second shell 13, so that the user can tear the release layer 25 off the protective layer 23 by pulling the end of the pull-out layer 27 extending outside the first shell 11 and the second shell 13 after the first shell 11 and the second shell 13 are covered, so as to reduce the risk of dust adhering to the protective layer 23 and improve the quality of the film.

[0032] An escape notch 103 is provided between the first shell 11 and the second shell 13 . The escape notch 103 connects the positioning space 101 with the outside. One end of the drawing layer 27 extends to the outside of the first shell 11 and the second shell 13 through the escape notch 103 .

[0033] It is understandable that the avoidance gap 103 may be provided on the first housing 11, or on the second housing 13, or may be provided partially on the first housing 11 and partially on the second housing 13. In this embodiment, the avoidance gap 103 is provided on the first housing 11.

[0034] The size of the positioning layer 21 is larger than that of the protective layer 23 , so a portion of the positioning layer 21 extends out of the protective layer 23 and is sandwiched between the first shell 11 and the second shell 13 to enhance the stability of the protective layer 23 .

[0035] In one embodiment, the film applicator 10 further includes a connecting structure 15, the connecting structure 15 includes a first side plate 153, a second side plate 153, and a connecting plate 155 connected between the first side plate 153 and the second side plate 153, the first side plate 153 and / or the second side plate 153 are flipped and connected with the connecting plate 155, the first shell 11 is relatively fixed to the first side plate 153, and the second shell 13 is relatively fixed to the second side plate 153. Specifically, the first side plate 153 and the second side plate 153 are flipped and connected with the connecting plate 155 respectively. When the first side plate 153 and the second side plate 153 are flipped relative to the connecting plate 155, the first shell 11 and the second shell 13 are driven to rotate, so that the first shell 11 and the second shell 13 are covered or separated from each other.

[0036] In this embodiment, when the first shell 11 and the second shell 13 are covered, the first side plate 153 and the second side plate 153 are spaced apart and parallel to each other, and the connecting plate 155 is vertically connected between the first side plate 153 and the second side plate 153 .

[0037] The connection method between the first shell 11 and the first side plate 153 and between the second shell 13 and the second side plate 153 is not limited, for example, mechanical fixing, gluing fixing, etc.

[0038] The connection method between the connecting plate 155 and the first side plate 153 and between the connecting plate 155 and the second side plate 153 is not limited, as long as it can be turned over, for example, through a rotating shaft, a hinge, a fold, etc.

[0039] It can be understood that the positioning space 101 is formed between the first shell 11 and the second shell 13 , which may mean that the positioning space 101 is opened in the first shell 11 or the second shell 13 , or that the positioning space 101 is partially located on the first shell 11 and partially located on the second shell 13 .

[0040] In this embodiment, the positioning space 101 includes an electronic device positioning cavity 111 provided in the first shell 11 and a protective film positioning cavity 131 provided in the second shell 13. When the first shell 11 and the second shell 13 are covered, the electronic device positioning cavity 111 and the protective film positioning cavity 131 are opposite and connected. When applying the film, the first shell 11 and the second shell 13 can be separated first, and then the electronic device can be stored in the electronic device positioning cavity 111 of the first shell 11, and the protective film 20 can be installed on the second shell 13 and cover the protective film positioning cavity 131, and then the first shell 11 and the second shell 13 can be covered, so that the protective layer 23 of the protective film 20 can be aligned with the screen of the electronic device, and then the release layer 25 can be torn off through the pull-out layer 27, and the protective layer 23 will be attached to the screen.

[0041] In one embodiment, an extrusion piece 16 is provided in the protective film positioning cavity 131. When the protective film 20 is installed on the second shell 13, the extrusion piece 16 is located between the positioning layer 21 and the second shell 13. When the first shell 11 and the second shell 13 are covered, the extrusion piece 16 will squeeze the protective film 20. Therefore, when the release film is torn off, the protective layer 23 can be attached to the screen under the action of the extrusion piece 16, thereby removing the bubbles between the protective layer 23 and the screen, forming an automatic exhaust effect.

[0042] Preferably, the extrusion member 16 is an elastic foam, which is relatively soft, has a certain elasticity, and can be deformed to avoid damaging the protective film 20 during the extrusion process.

[0043] The specific shape of the extrusion piece 16 is not limited. In the present embodiment, the extrusion piece 16 is in the shape of an elongated strip. The extrusion piece 16 extends from one side of the protective film positioning cavity 131 toward the other opposite side, and the extension direction of the extrusion piece 16 is the same as the extension direction of the pulling layer 27, that is, the extrusion piece 16 extends along the direction of tearing off the release layer 25, so that the release layer 25 is torn off on one side and the exposed protective layer 23 is pressed tightly against the screen on the other side, thereby achieving a more uniform exhaust effect.

[0044] The specific position of the extrusion piece 16 is not limited, and it can be located in the middle of the protective film positioning cavity 131, or it can be located on the side of the protective film positioning cavity 131. In this embodiment, along the direction perpendicular to the extension of the extrusion piece 16, the extrusion piece 16 is located in the middle of the protective film positioning cavity 131, so in the process of tearing off the release layer 25, the middle of the protective layer 23 is first attached to the screen, and then diffused to both sides, so as to form a better exhaust effect and improve the film quality.

[0045] In one embodiment, the first shell 11 and / or the second shell 13 are provided with reinforcing ribs 112. Specifically, the first shell 11 and the second shell 13 are both provided with reinforcing ribs 112. Since the film applicator 10 is used to assist the tablet computer in applying a film, the overall volume is relatively large. By providing the reinforcing ribs 112 on the first shell 11 and the second shell 13, the overall strength of the first shell 11 and the second shell 13 can be enhanced, thereby reducing the risk of bending and deformation of the first shell 11 and the second shell 13.

[0046] In one embodiment, reinforcing ribs 112 are provided on both sides of the first shell 11 and the second shell 13 that are close to each other and on both sides that are away from each other, and reinforcing ribs 112 are provided on both sides of the first shell 11 and the second shell 13 that are close to the positioning space 101 and on both sides that are away from the positioning space 101, so as to further enhance the overall strength of the first shell 11 and the second shell 13.

[0047] The specific shape of the reinforcing rib 112 is not limited, such as a long strip or a V-shape. When the reinforcing rib 112 is in a long strip shape, it can be parallel to or inclined with the corresponding side of the first shell 11 or the second shell 13.

[0048] The specific number of the reinforcing ribs 112 is not limited. In one embodiment, the first shell 11 and the second shell 13 are provided with multiple reinforcing ribs 112 on the sides close to the positioning space 101 and away from the positioning space 101. The multiple reinforcing ribs 112 located on the same side of the first shell 11 are arranged at intervals, and the multiple reinforcing ribs 112 located on the same side of the second shell 13 are arranged at intervals.

[0049] In one embodiment, a matching concave-convex structure 17 is provided between the first shell 11 and the second shell 13. The concave-convex structure 17 surrounds the outer periphery of the positioning space 101. The concave-convex structure 17 can form a limiting effect to enhance the stability of the first shell 11 and the second shell 13 in the covered state.

[0050] In this embodiment, the concave-convex structure 17 includes a first protrusion 171 provided on the first shell 11, a first recess 173 provided on the second shell 13, a second protrusion 175 provided on the second shell 13, and a second recess 177 provided on the first shell 11. The first protrusion 171 and the second recess 177 are alternately distributed along the circumference of the protective film positioning cavity 131, and the second protrusion 175 and the first recess 173 are alternately distributed along the circumference of the electronic device positioning space 101, and the first protrusion 171 corresponds to the first recess 173, and the second protrusion 175 corresponds to the second recess 177. When the first shell 11 and the second shell 13 are covered, the first protrusion 171 is inserted into the first recess 173, and the second protrusion 175 is inserted into the second recess 177, forming a similar meshing effect to enhance stability.

[0051] Specifically, there are multiple first protrusions 171 and first recesses 173 as well as multiple second protrusions 175 and second recesses 177 , and they correspond one to one.

[0052] In other embodiments, the concavo-convex structure 17 may include only the first protrusion 171 and the first concave 173 , or only the second protrusion 175 and the second concave 177 .

[0053] In one embodiment, a protective film positioning structure 19 is provided between the first shell 11 and the second shell 13. The protective film positioning structure 19 is used to cooperate with the positioning layer 21 of the protective film 20 to form a positioning effect on the protective film 20 so that the protective layer 23 can be aligned with the screen of the electronic device.

[0054] The protective film positioning structure 19 includes a positioning column 191 provided on the second shell 13 and a positioning hole 193 correspondingly provided on the first shell 11. The positioning column 191 is located outside the protective film positioning cavity 131, and the positioning hole 193 is located outside the electronic device positioning cavity 111. Specifically, the positioning column 191 is provided in the first recess 173 of the second shell 13, and the positioning hole 193 is provided on the first protrusion 171 of the first shell 11. A through hole is provided on the positioning layer 21 of the protective film 20.
