DETAILED DESCRIPTION

[0029] 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.

[0030] 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.

[0031] 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.

[0032] See also Figures 1 to 8 An embodiment of the utility model provides a device including a film applicator 1 and a protective film. The film applicator 1 is used to assist a user in attaching the protective film to the screen of an electronic device such as a mobile phone or a tablet computer.

[0033] The film applicator 1 includes a base 10, an upper cover 20, a connecting member 30 and a film pressing member 40. The base 10 is provided with a positioning space 101 for accommodating and positioning the electronic device. One end of the upper cover 20 is a connecting end 21, which is rotatably connected to the base 10. The film pressing member 40 is slidably arranged on the base 10. The two ends of the connecting member 30 are rotatably connected to the upper cover 20 and the film pressing member 40, respectively, so that when the upper cover 20 rotates relative to the base 10, the film pressing member 40 can be driven by the connecting member 30 to slide relative to the base 10. The protective film is located between the film pressing member 40 and the base 10 and covers the positioning space 101. Therefore, the film pressing member 40 can squeeze the protective film during the sliding process, so that the protective film is attached to the screen of the electronic device. By driving the film pressing member 40 to slide relative to the base 10 by rotating the upper cover 20, compared with the method of directly pushing the film pressing member 40 by hand, the problem of uneven force causing the quality of film application can be effectively avoided.

[0034] Specifically, the protective film has a protective layer and a release layer and a positioning layer respectively attached to opposite sides of the protective layer. The release layer is used to protect the stickiness of the protective layer, and the positioning layer is used to cooperate with the film applicator to form a positioning effect, so that the protective layer is aligned with the electronic device in the positioning space, and the protective layer is used to be attached to the screen of the electronic device. When applying the film, the release layer can be torn off first, and then the positioning layer is lowered to connect with the base, and finally the upper cover 20 is rotated, and the upper cover 20 drives the film pressing member 40 to pass over the positioning space 101, and squeezes the positioning layer and the protective layer downward, so that the protective layer is attached to the screen of the electronic device.

[0035] The film pressing member 40 has an initial position and an end position relative to the positioning space 101. The initial position is the position of the film pressing member 40 before the film sticking operation is performed, and the end position is the position of the film pressing member 40 after the film sticking is completed. The initial position is closer to the connecting end 21 of the upper cover 20 than the end position. The upper cover 20 can rotate relative to the base 10 to drive the film pressing member 40 to reciprocate between the initial position and the end position through the connecting member 30.

[0036] When the film pressing member 40 is in the initial position, the angle between the upper cover 20 and the base 10 is greater than 90°, and an obtuse angle is formed between the base 10 and the upper cover 20, so that the user can save more effort when rotating the upper cover 20 to move the film pressing member 40 from the initial position to the terminal position, so that the user can perform the film sticking operation.

[0037] It is understandable that in order to further ensure the quality of film application, the upper cover 20 can be rotated to make the film pressing member 40 repeatedly move between the initial position and the end position, so that the film pressing member 40 repeatedly squeezes the protective film to fully remove the bubbles between the protective film and the screen.

[0038] When the film pressing member 40 is at the end position, the upper cover 20 covers the base 10, and the angle between the upper cover 20 and the base 10 is 0°, so as to reduce the overall volume of the film applicator 1 in this state for storage and carrying.

[0039] The connecting member 30 rotates relative to the film pressing member 40 and has a first rotation point, the connecting member 30 rotates relative to the upper cover 20 and has a second rotation point, and the upper cover 20 rotates relative to the base 10 and has a third rotation point. Specifically, both ends of the connecting member 30 are connected to the film pressing member 40 and the upper cover 20, and the upper cover 20 and the base 10 through a rotating shaft, the connecting member 30 rotates relative to the film pressing member 40 and the upper cover 20 around the corresponding rotating shaft, and the upper cover 20 rotates relative to the base 10 around the corresponding rotating shaft. The first rotation point, the second rotation point and the third rotation point are respectively located on the central axis of the corresponding rotating shaft and are located in the same plane. The first rotation point and the second rotation point are connected to form a first direction, the first rotation point and the third rotation point are connected to form a second direction, and the second rotation point and the third rotation point are connected to form a third direction. An angle β is formed between the first direction and the second direction, and an angle γ is formed between the second direction and the third direction. During the rotation of the upper cover 20 relative to the base 10, the angle β is less than or equal to 90°, and the angle γ is less than or equal to 90°.

[0040] The specific connection method between the upper cover 20 and the base 10 is not limited. In one embodiment, the connection end 21 of the upper cover 20 is rotatably connected to the base 10 through one or more rotating shafts, so that the upper cover 20 can rotate relative to the base 10 around the rotating shaft.

[0041] A storage space 201 is provided on one side of the upper cover 20 close to the connector 30 . The storage space 201 can avoid the connector 30 when the film pressing member 40 moves from the initial position to the terminal position. When the film pressing member 40 is at the terminal position, the connector 30 is stored in the storage space 201 .

[0042] An upper cover reinforcement rib 22 is disposed in the storage space 201 to enhance the overall strength of the upper cover 20 .

[0043] One end of the upper cover 20 is rotatably connected to one end of the base 10, and the other end of the upper cover 20, that is, the end away from the connection end 21, and the other end of the base 10 are respectively provided with notches 202, and the two notches 202 are opposite and connected, so that when the upper cover 20 is covered on the base 10, the user can insert a finger into the notch 202 and press against the upper cover 20, so as to facilitate the user to rotate the upper cover 20. In other embodiments, the notch 202 may be provided only on the upper cover 20 or the base 10, which can also facilitate the user to rotate the upper cover 20.

[0044] The base 10 is also provided with a hand grip 102, which is opposite to the notch 202 on the base 10 and connected to the positioning space 101, so that after the user completes the film application, he can put his fingers into the hand grip 102 and press against the electronic device in the positioning space 101, making it convenient for the user to take out the electronic device after completing the film application.

[0045] In one embodiment, the base 10 is provided with a slide rail 11, and the film pressing member 40 is slidably matched with the slide rail 11 so that the film pressing member 40 can slide relative to the base 10. When the upper cover 20 rotates relative to the base 10, the film pressing member 40 is driven to extend along the length direction of the slide rail 11 through the connecting member 30.

[0046] The specific number of the slide rails 11 is not limited. In the present embodiment, the slide rails 11 are respectively provided on the opposite sides of the base 10, and the two ends of the film pressing member 40 are respectively slidably matched with the two slide rails 11, so that the film pressing member 40 is more stable during operation.

[0047] Preferably, the end of the slide rail 11 close to the connection end 21 is an arc segment 111. When the film pressing member 40 is in the initial position, the film pressing member 40 is located in the arc segment 111. Specifically, the arc segment 111 has a first segment 1111 and a second segment 1112 in the direction away from the connection end 21. In the vertical direction, the height of the first segment 1111 gradually decreases in the direction toward the connection end 21, and the height of the second segment 1112 gradually decreases in the direction away from the connection end 21. When the film pressing member 40 is in the initial position, the film pressing member 40 is located in the first segment 1111. The vertical direction is the direction perpendicular to a plane when the film applicator is placed on the plane, that is, the axial direction of the positioning space 101. The arc segment 111 first extends upward for a distance toward the direction close to the connecting end 21, and then extends downward for a distance. When the film pressing member 40 moves from the second segment 1112 to the first segment 1111, the film pressing member 40 will gradually move downward, so that the rotation center of the upper cover 20 moves downward, thereby increasing the rotation angle of the upper cover 20, so that an obtuse angle is formed between the upper cover 20 and the base 10.

[0048] In one embodiment, the film pressing member 40 includes a sliding portion 42 and a film pressing portion 43. The sliding portion 42 is slidably connected to the base 10, the film pressing portion 43 is mounted on the sliding portion 42, and one end of the connecting member 30 is rotatably connected to the sliding portion 42. Specifically, grooves 420 are respectively provided at both ends of the sliding portion 42, and the sliding portion 42 is slidably matched with the slide rail 11 of the base 10 through the grooves 420. When the upper cover 20 rotates relative to the base 10, the connecting member 30 drives the sliding portion 42 to slide along the length direction of the slide rail 11, and the sliding portion 42 drives the film pressing portion 43 to move, so that the film pressing portion 43 squeezes the protective film to complete the film sticking operation.

[0049] Preferably, when the film pressing member 40 is in the final position, the upper cover 20 covers the base 10, and the film pressing portion 43 does not exceed the positioning space 101, that is, when the film pressing member 40 is in the final position, the film pressing portion 43 is at least partially still located above the positioning space 101. At this time, the film pressing portion 43 still presses the protective layer on the screen of the electronic device to avoid the problem that when the film pressing member 40 moves from the final position to the initial position, the film pressing member 40 back presses the protective layer of the protective film, causing the protective layer to warp and form bubbles between the screen and the protective layer.

[0050] In this embodiment, the positioning space 101 is a rectangular positioning groove, which has four side walls 103 connected in sequence in the circumferential direction. When the film pressing member 40 is at the end position, there is a gap between the part where the film pressing part 43 presses the protective layer onto the screen and the corresponding side wall 103.

[0051] It is understandable that the specific method of controlling the film pressing part 43 not to exceed the positioning space 101 is not limited. For example, a limiting structure may be provided to limit the movement distance of the sliding part 42 so that the film pressing part 43 does not exceed the positioning space 101.

[0052] The specific type of the film pressing part 43 is not limited, such as a roller, a scraper, etc., as long as it can achieve the effect of film pressing. In this embodiment, the film pressing part 43 includes a roller 431 and a convex shaft part 432 respectively provided at both ends of the roller 431, and the roller 431 rotates with the sliding part 42 through the convex shaft part 432. When the upper cover 20 drives the sliding part 42 to slide, the roller 431 rotates relative to the sliding part 42 and rolls over the protective film to squeeze out the bubbles between the protective layer and the screen. At the same time, the rolling method can avoid damaging the protective layer or shifting the position of the protective layer during the film application process.

[0053] Preferably, the hardness of the roller 431 is 50-65 degrees, and the diameter of the roller 431 is 9-11 mm, so that the roller 431 can better discharge bubbles during the process of squeezing the protective film.

[0054] The base 10 is provided with a slide groove 112, and the film pressing member 40 further includes a bearing 44 provided on the convex shaft portion 432, and the bearing 44 is located in the slide groove 112. Specifically, the slide grooves 112 are respectively provided on the opposite sides of the slide rail 11, and the convex shaft portions 432 at both ends of the roller 431 are respectively inserted into the corresponding slide grooves 112, and the bearing 44 is located between the convex shaft portion 432 and the slide rail 11, so as to reduce the friction between the film pressing member 40 and the base 10, so that the film pressing member 40 can slide more smoothly relative to the base 10.

[0055] Please refer to Figure 8In one embodiment, the sliding part 42 is provided with a receiving part 421 and a mounting groove 423 communicating with the receiving part 421, one end of the mounting groove 423 extends to the bottom of the sliding part 42 and forms an opening 424, the roller 431 is received in the receiving part 421, and the convex shaft part 432 is inserted into the mounting groove 423 through the opening 424, so that the roller 431 is detachably mounted on the sliding part 42. During the assembly process, the bearings 44 can be respectively sleeved on the two convex shaft parts 432, and then the convex shaft part 432 is pushed into the mounting groove 423 through the opening 424 to mount the film pressing part 43 to the sliding part 42, and finally the combination of the film pressing part 43 and the bearing 44 is slidably mounted on the base 10.

[0056] In one embodiment, the base 10 includes a base body 12 and a bottom bracket 13 detachably connected to the base body 12, a positioning space 101 is provided on the bottom bracket 13, the upper cover 20 is rotatably connected to the base body 12, and the film pressing member 40 is slidably connected to the base body 12. Since the base 10 includes a detachable base body 12 and a bottom bracket 13, the user can replace different bottom brackets 13 according to the specific model of the electronic device, and different bottom brackets 13 have positioning spaces 101 of different sizes, so that the film applicator 1 can be applied to different electronic devices, thereby broadening the application range of the film applicator 1.

[0057] The specific connection method between the seat body 12 and the base 13 is not limited, such as snap fit, interference fit, etc.

[0058] One end of the connecting member 30 is detachably connected to the film pressing member 40, and the film pressing member 40 is detachably connected to the base 12, that is, after the connecting member 30 is connected to the film pressing member 40, it can form both a rotation effect and a detachable effect, and after the film pressing member 40 is connected to the base 12, it can form both a sliding effect and a detachable effect. When replacing the bottom bracket 13, the connecting member 30 can be separated from the film pressing member 40 first, so that the rotation of the upper cover 20 will not be affected by the film pressing member 40, so as to form a larger angle with the base 10, and then the film pressing member 40 can be separated from the base 12 to prevent the upper cover 20 and the film pressing member 40 from affecting the replacement of the bottom bracket 13, so that the user can replace the bottom bracket 13.

[0059] The base body 12 is provided with a base reinforcement rib 14 on the outer side of the slide rail 11 to enhance the overall strength of the base 10 .

[0060] In one embodiment, the base 10 is provided with a positioning structure 15, and the positioning structure 15 includes a positioning column 151 and a hook 152 respectively arranged on opposite sides of the positioning space 101, and the two ends of the positioning layer of the protective film are correspondingly provided with positioning holes and hanging holes. The positioning holes cooperate with the positioning columns 151, and the hanging holes cooperate with the hooks 152, thereby forming a positioning effect on both ends of the protective film to enhance the stability of the protective layer of the protective film during the film-sticking process.

[0061] The specific positions of the positioning column 151 and the hook 152 are not limited, and they can be set on the seat body 12 or on the base 13 .

[0062] The positioning column 151 is provided with a limiting portion 153 protruding outward, and the limiting portion 153 is located on the side of the protective film away from the base 10. Therefore, the limiting portion 153 can prevent the positioning layer of the protective film from separating from the positioning column 151 when the film pressing member 40 squeezes the protective film.

[0063] The hook 152 extends from the base 10 in a direction away from the positioning space 101. The base 10 is provided with an escape portion 105. One end of the hook 152 away from the positioning space 101 extends above the escape portion 105 or into the escape portion 105 so that the hook 152 passes through the hanging hole.

[0064] Please refer to Figure 5 In one embodiment, the base 10 is provided with an avoidance hole 106 connected to the positioning space 101, and the avoidance hole 106 is located at one end of the positioning space 101. The avoidance hole 106 is located at the bottom of the positioning space 101, and can avoid the camera on the electronic device, so that the electronic device can be placed flatly in the positioning space 101, and can also prevent the electronic device from being placed upside down.

[0065] Please refer to Figure 6 In another embodiment, the base 10 is provided with a avoidance window 107 connected to the positioning space 101, and the avoidance window 107 is slightly smaller than the positioning space 101, so that a support portion is formed at the periphery of the avoidance window 107 to support the electronic device. The avoidance window 107 is located at the bottom of the positioning space 101, which can not only avoid the camera of the electronic device, but also allow the user to push up the electronic device through the avoidance window 107 after the film is applied, so that the user can take out the electronic device from the positioning space 101 conveniently.

[0066] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
