Description

Mobile phone film auxiliary device Technical Field

[0001] The utility model relates to the technical field of film pasting, in particular to a mobile phone film pasting auxiliary device. Background Art

[0002] Mobile phones have become an indispensable communication tool in people's lives. However, due to frequent use, mobile phone screens are easily dirty or even scratched. Mobile phone screens are generally protected by applying mobile phone screen protectors (such as tempered glass screen protectors). However, when applying tempered glass screen protectors, most people rely on their experience to determine whether the tempered glass screen protectors are applied flatly and completely cover the mobile phone screen. Such operation can easily cause the tempered glass screen protectors to be applied crookedly or require multiple adjustments.

[0003] To this end, Chinese patent CN218499169 U discloses a mobile phone screen film with a tear-off cleaning function (as shown in Figure 1), which includes a tempered film, a tempered film protective film and a tear-off tape. The tempered film protective film is adhered to the surface of the tempered film, and the other side of the tempered film protective film is provided with a tear-off tape. When applying the film, the mobile phone screen film is placed inside the mobile phone positioning frame, and one side of the tear-off tape is ensured to correspond to the screen of the mobile phone. Then, the mobile phone screen film with the screen film is buckled on the side wall of the mobile phone. At the same time, the tear-off tape is pulled down and pulled out from the notch at the bottom of the mobile phone positioning frame, that is, the tempered film protective film is pulled out from between the tempered film and the mobile phone screen. While being pulled out, the tempered film acts on the mobile phone screen to achieve application. During the process of pulling out the tempered film protective film, its adhered side contacts the mobile phone screen, thereby completing the film application on the mobile phone screen. Although this technology solves the problems of crooked and uneven application of tempered film that occur when applied manually, since the user needs to press the phone when applying the film, there is a problem of uneven force, especially the contact part between the tempered film and the phone screen is difficult to bear force. After the film is applied, it is very easy for bubbles to remain, resulting in poor film application effect.

[0037] Example 1

[0038] As shown in FIG2 , FIG2 is a structural diagram of the first embodiment of the present invention.

[0039] This embodiment provides a mobile phone film-sticking auxiliary device, including a base plate 1, a cover plate 2 and a connecting plate 3; the base plate 1 and the cover plate 2 are both located on the connecting plate 3, wherein a fold 31 is provided in the middle position of the connecting plate 3, the base plate 1 is located below the fold 31, and the cover plate 2 is located above the fold 31. When the connecting plate 3 is flipped around the fold 31, the cover plate 2 can be correspondingly buckled and fixed together with the base plate 1.

[0040] A lower limit frame 11 is provided on the base plate 1 , and the lower limit frame 11 cooperates with the base plate 1 to form a lower accommodating space 12 for placing a mobile phone film (see FIG. 1 ) and a mobile phone.

[0041] The lower retaining frame 11 includes two opposing second long sides 111 and two second short sides 112. The rectangular frame formed by the second long sides 111 and the second short sides 112 secures the phone in place. Grooves 114 are provided on the two second long sides 111 to facilitate the removal of the phone from the lower retaining frame 11. A drawer slot 115 is provided on the lower second short side 112. When the phone screen protector is placed in the lower retaining frame 11, the tear-off strap fits into the corresponding drawer slot 115, exposing the lower retaining frame 11.

[0042] An upper limit frame 21 is provided on the cover plate 2 and can be buckled with the lower limit frame 11. The upper limit frame 21 and the cover plate 2 cooperate to form an upper accommodating space 22, which corresponds to the lower accommodating space 12, wherein the upper limit frame 21 includes two first long frames 211 and two first short frames 212 arranged opposite to each other.

[0043] The lower limit frame 11 is provided with a slot 113 on each of its four corners, and the upper limit frame 21 is provided with a post 213 on each of its four corners that engages with the slot 113. When the upper limit frame 21 is buckled onto the lower limit frame 11, the post 213 engages with the slot 113, ensuring that the lower limit frame 11 and the upper limit frame 21 are firmly and stably buckled.

[0044] A first protrusion 221 is provided in the upper accommodating space 22; a second protrusion 121 corresponding to the position of the first protrusion 221 is provided in the lower accommodating space 12. When the cover plate 2 is correspondingly buckled with the substrate 1, the back cover of the mobile phone to be film-coated, which is located between the lower limit frame 11 and the upper limit frame 21, abuts against the first protrusion 221, and the mobile phone film located in the lower limit frame 11 abuts against the second protrusion 121. At this time, the first protrusion 221 forms a downward pressure on the back cover of the mobile phone, and the second protrusion 121 forms an upward pressure on the mobile phone film. At this time, the hand-tear tape is pulled out from the drawing groove 115 at the bottom of the lower accommodating space 12, driving the tempered film protective film to be pulled out from between the tempered film and the mobile phone screen. At the same time, due to the above-mentioned pressure, the middle of the mobile phone screen contacts the tempered film and gradually diffuses to the surrounding area, thereby forming an exhaust effect from the middle to the edge, to ensure that there is no bubble residue after the film is pasted.

[0045] In this embodiment, the first protrusion 221 is located at the midline of the two first long sides 211 , and the first protrusion 221 is 0-10 mm higher than other planes in the upper accommodating space 22 , preferably 2 mm in this embodiment.

[0046] Likewise, the second protrusion 121 is located at the midline of the two second long sides 111 , and the second protrusion 121 is 0-10 mm higher than other planes in the lower accommodating space 12 , preferably 2 mm in this embodiment.

[0047] It should be noted that the shape and position of the first protrusion 221 and the second protrusion 121 can be adjusted according to actual conditions. In this embodiment, the first protrusion 221 is circular and the second protrusion 121 is bar-shaped, and they are respectively located at the center of the upper accommodating space 22 and the lower accommodating space 12, so that the force is more evenly distributed during film application and the air exhaust effect is better. Similarly, the shapes of the first protrusion 221 and the second protrusion 121 can also be the same, such as both circular or both bar-shaped, which can be different according to the specific usage environment and requirements.

[0048] In addition, an anti-foolproof groove 222 is provided in the upper accommodating space 22. The position of the anti-foolproof groove 222 varies depending on the model of the mobile phone. When applying a film to the mobile phone, the protrusions such as the camera on the back of the mobile phone can be located in the anti-foolproof groove 222, thereby ensuring that the contact surface with the back cover of the mobile phone is a plane to ensure uniform force.

[0049] Example 2

[0050] As shown in FIG3 , FIG3 is a structural diagram of the second embodiment of the present utility model.

[0051] The mobile phone film application auxiliary device of this embodiment includes a base plate 1, a cover plate 2, and a connecting plate 3. Both the base plate 1 and the cover plate 2 are positioned on the connecting plate 3, with a fold 31 provided in the middle of the connecting plate 3. Compared with the first embodiment, the base plate 1 is positioned to the right of the fold 31, while the cover plate 2 is positioned to the left of the fold 31. When the connecting plate 3 is flipped around the fold 31, the cover plate 2 can be fixedly fastened to the base plate 1.

[0052] Of course, depending on the specific usage, the base plate 1 can also be located on the left side of the fold 31, and the cover plate 2 can be located on the right side of the fold 31. The position and shape of the anti-mock groove 222, the first protrusion 221, and the second protrusion 121 can also vary according to actual circumstances. For example, in this embodiment, the first protrusion 221 and the second protrusion 121 are circular.

[0053] Example 3

[0054] As shown in FIG4 , FIG4 is a structural diagram of the third embodiment of the present utility model.

[0055] The mobile phone film application auxiliary device of this embodiment includes a base plate 1 and a cover plate 2. The side edges of the cover plate 2 are movably connected to the side edges of the base plate 1 so that the cover plate 2 can rotate around the side connection to correspondingly engage with the base plate 1. In this embodiment, the base plate 1 and the cover plate 2 are connected together by the left and right side edges.

[0056] The structure of the base plate 1 is basically the same as that of the embodiment 1, but the cover plate 2 is different. A first protrusion 221 is formed on the cover plate 2. The first protrusion 221 and the cover plate 2 form a gap, which is equivalent to the anti-fool groove in the embodiment 1.

[0057] When the substrate 1 and the cover plate 2 are buckled together, the first protrusion 221 in this embodiment contacts the back cover of the mobile phone to be filmed, and the mobile phone film located in the lower limit frame 11 of the substrate 1 contacts the second protrusion 121. At this time, the first protrusion 221 forms a downward pressure on the back cover of the mobile phone, and the second protrusion 121 forms an upward pressure on the mobile phone film. At this time, the hand-tear tape is pulled out from the pull-out groove 115 at the bottom of the lower accommodating space 12, driving the tempered film protective film to be pulled out from between the tempered film and the mobile phone screen. At the same time, due to the above-mentioned pressure, the middle of the mobile phone screen contacts the tempered film and gradually diffuses to the surrounding area, thereby forming an exhaust effect from the middle to the edge, to ensure that there is no bubble residue after the film is applied.

[0058] Example 4

[0059] As shown in FIG5 , FIG5 is a structural diagram of a fourth embodiment of the present utility model.

[0060] The mobile phone film application auxiliary device of this embodiment includes a base plate 1 and a cover plate 2. The side edges of the cover plate 2 are movably connected to the side edges of the base plate 1 so that the cover plate 2 can rotate around the side edge connection to correspondingly engage with the base plate 1. In this embodiment, the base plate 1 and the cover plate 2 are connected together by upper and lower side edges.

[0061] The base plate 1 is provided with an outer frame 4, and a lower limit frame 11 is provided inside the outer frame 4. The lower limit frame 11 cooperates with the base plate 1 to form a lower accommodating space 12 for placing a mobile phone film (see Figure 1) and a mobile phone. The lower limit frame 11 includes two second long frames 111 and two second short frames 112 arranged opposite to each other. The second long frames 111 and the second short frames 112 form a rectangular frame to fix the mobile phone. Grooves 114 are provided on the two second long frames 111 to facilitate the removal and placement of the mobile phone from the lower limit frame 11. A pull-out slot 115 is provided on the lower second short frame 112. A reversible folding edge 41 is provided on the outer frame 4 near the pull-out slot 115. A baffle 42 is provided between the folding edge 41 and the pull-out slot 115. The baffle 42 has an open slot 421 corresponding to the position of the pull-out slot 115.

[0062] When not in use, the folded edge 41 flips inward and forms a sealed cavity with the baffle 42 to prevent dust from entering the film-sticking area. When in use, the mobile phone film is placed in the lower limit frame 11, and the hand-tear tape can pass through the pull-out groove 115 and out of the opening groove 421. The mobile phone is placed in the lower limit frame 11 to press the mobile phone film. At this time, the cover plate 2 is flipped downward around the side connection to make it correspondingly buckled with the substrate 1, and the first protrusion 221 forms a downward pressure on the back cover of the mobile phone, and the second protrusion 121 forms an upward pressure on the mobile phone film. At this time, the folded edge 41 flips outward and disengages from the baffle 42, exposing the opening groove 421. The hand-tear tape is pulled out from the opening groove 421, driving the tempered film protective film to be pulled out from between the tempered film and the mobile phone screen. At the same time, due to the above-mentioned pressure, the middle of the mobile phone screen contacts the tempered film and gradually diffuses to the surrounding area, thereby forming an exhaust effect from the middle to the edge to ensure that there is no bubble residue after the film is applied.

[0063] Example 5

[0064] As shown in FIG6 , FIG6 is a structural diagram of the fifth embodiment of the present utility model.

[0065] The mobile phone film application auxiliary device of this embodiment is different from that of the fourth embodiment in that a baffle 42 is provided at a position of the outer frame 4 close to the pull-out slot 115 , and an opening slot 421 corresponding to the position of the pull-out slot 115 is provided on the baffle 42 .

[0066] Example 6

[0067] As shown in FIG7 , FIG7 is a structural diagram of a sixth embodiment of the present utility model.

[0068] The mobile phone screen protector application assisting device of this embodiment differs from the fifth embodiment only in that a middle box 5 with the same structure as the base plate 1 is disposed between the base plate 1 and the cover plate 2. This design allows for screen protector application for different types of mobile phones. For example, when applying screen protector to a certain model of mobile phone, the middle box 5 is first fastened to the cover plate 2, and then the mobile phone is placed in the lower retaining frame 11 of the base plate 1. The cover plate 2 and the middle box 5 are now fastened together, acting as a new cover plate. The protrusion formed by the bottom of the middle box 5 presses the back cover of the mobile phone in the lower retaining frame 11 of the base plate 1. At this point, the hand-tear tape is pulled out from the drawer slot 115 to complete the screen protector application to the mobile phone.

[0069] Similarly, when applying a film to another model of mobile phone, first fasten the middle box 5 and the base plate 1 together, and then place the mobile phone in the limit frame in the middle box 5. At this time, the protrusion on the cover plate 2 presses the back cover of the mobile phone downward, and the other protrusion in the middle box 5 forms an upward pressure on the mobile phone film. At this time, pull the hand-tear tape out of the drawer slot of the middle box to complete the film application on the mobile phone.
