[0003] The technical objective of this utility model is to provide a mobile phone screen protector applicator, which aims to solve the technical problem that in related technologies, users basically apply the screen protector to the back of the mobile phone by simply aligning it by feel, which easily leads to deviations and unsightly results.

[0004] To solve the above-mentioned technical problems, this utility model is implemented as follows: a mobile phone screen protector applicator for assisting in applying a mobile phone back film. The applicator includes a frame that encloses a receiving space for accommodating a mobile phone. The thickness of the frame is less than the thickness of the mobile phone. The frame has a first side and a second side arranged opposite to each other along the thickness direction. The first side has a first side edge and a second side edge spaced apart along the width direction, and a third side edge and a fourth side edge spaced apart along the length direction. The first side edge and the second side edge are each provided with at least one first positioning structure, and the third side edge and / or the fourth side edge are provided with at least one second positioning structure. When the mobile phone is accommodated in the receiving space, the back panel of the mobile phone and the first side edge face the same side.

[0005] Furthermore, in some embodiments, the first positioning structure includes a base protruding from the corresponding side and a connecting portion protruding from the base away from the corresponding side, wherein the projection surface of the base along the thickness direction covers the connecting portion, and the connecting portion is used to connect the back film of the mobile phone.

[0006] Furthermore, in some embodiments, the second positioning structure includes a base protruding from the corresponding side and a connecting portion protruding from the base away from the corresponding side, wherein the projection surface of the base along the thickness direction covers the connecting portion, and the connecting portion is used to connect the back film of the mobile phone.

[0007] Furthermore, in some embodiments, the first side is further provided with a plurality of support columns arranged at intervals along the circumference. The support columns are spaced apart from the first positioning structure and from the second positioning structure, and the dimension of the support column along the thickness direction is equal to the dimension of the base along the thickness direction.

[0008] Furthermore, in some embodiments, the first positioning structure extends along the length direction, and / or the second positioning structure extends along the width direction.

[0009] Furthermore, in some embodiments, the connecting portion of the first positioning structure is provided with a chamfered structure, and / or the connecting portion of the second positioning structure is provided with a chamfered structure.

[0010] Furthermore, in some embodiments, the receiving space is further provided with a plurality of limiting parts that protrude from the frame and are arranged at intervals along the circumference.

[0011] Furthermore, in some embodiments, the limiting portion is made of a flexible material.

[0012] Furthermore, in some embodiments, the frame is provided with an annular groove, the opening of which faces the second side.

[0013] Furthermore, in some embodiments, a screen protector assembly includes a mobile phone back film and a screen protector applicator. The mobile phone back film has a first positioning hole corresponding to the first positioning structure and a second positioning hole corresponding to the second positioning structure. The mobile phone back film has an adhesive surface disposed on the first side, and the first positioning structure is connected to the first positioning hole, and the second positioning structure is connected to the second positioning hole.

The mobile phone is housed within the housing space, with the back panel facing the first side of the frame and the screen facing the second side of the frame. Thus, the first and second positioning structures face the same side as the back panel, allowing for proper positioning of the back film. This guides the back film's application to the back panel, preventing positional deviations and ensuring aesthetics. Furthermore, since the frame's thickness is less than the phone's thickness—meaning when the first side is facing up and the second side is facing down (i.e., the back panel is facing up and the screen is facing down)—the first side of the frame is lower than the back panel. Therefore, the frame can position the back film using the positioning structure, while also preventing the adhesive surface of the back film from adhering to the first side of the frame, facilitating separation of the back film from the frame.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please see Figures 1 to 3 This utility model provides a mobile phone screen protector applicator for assisting in applying a mobile phone back film 2. The applicator includes a frame 1, which encloses a receiving space 11 for accommodating the mobile phone. The thickness of the frame 1 is less than the thickness of the mobile phone. The frame 1 has a first side 12 and a second side 13 arranged opposite to each other along the thickness direction. The first side 12 has a first side edge and a second side edge spaced apart along the width direction, and a third side edge and a fourth side edge spaced apart along the length direction. The first side edge and the second side edge are each provided with at least one first positioning structure 121, and the third side edge and / or the fourth side edge are provided with at least one second positioning structure 122. When the mobile phone is accommodated in the receiving space 11, the mobile phone back panel and the first side edge 12 face the same side.

[0027] In this embodiment of the present invention, the first side 12 of the frame 1 has four sides, and a first positioning structure 121 is provided on the first side and the second side of the first side 12, and a second positioning structure 122 is provided on the third side and / or the fourth side of the first side 12. The mobile phone is housed in the housing space 11, with the back panel of the mobile phone facing the first side 12 of the frame 1 and the screen of the mobile phone facing the second side 13 of the frame 1. Thus, the first positioning structure 121 and the second positioning structure 122 face the same side as the back panel of the mobile phone. The first positioning structure 121 and the second positioning structure 122 can be used to position the back film 2 of the mobile phone, which can guide the back film 2 to be pasted on the back panel of the mobile phone, thereby avoiding positional deviation of the back film 2 and ensuring aesthetics. In addition, since the thickness of the frame 1 is less than the thickness of the phone, that is, when the first side 12 is facing up and the second side 13 is facing down; that is, when the back panel of the phone is facing up and the screen of the phone is facing down, the first side 12 of the frame 1 is lower than the back panel of the phone. Therefore, the frame 1 can achieve the positioning of the back film 2 of the phone through the positioning structure. At the same time, it can also prevent the adhesive surface of the back film 2 used to stick the back panel of the phone from sticking to the surface of the first side 12 of the frame 1, which is conducive to the separation of the back film 2 of the phone and the frame 1.

[0028] Furthermore, in some embodiments, the first positioning structure 121 includes a base 1201 protruding from the corresponding side and a connecting portion 1202 protruding from the base 1201 away from the corresponding side. The projection surface of the base 1201 along the thickness direction covers the connecting portion 1202, and the connecting portion 1202 is used to connect the mobile phone back film 2.

[0029] And / or, the second positioning structure 122 includes a base 1201 protruding from the corresponding side and a connecting portion 1202 protruding from the base 1201 away from the corresponding side. The projection surface of the base 1201 along the thickness direction covers the connecting portion 1202, and the connecting portion 1202 is used to connect the mobile phone back film 2.

[0030] In some embodiments, the first positioning structure 121 disposed on the first side includes a base 1201 protruding from the surface of the first side and a connecting portion 1202 protruding from the base 1201 and facing away from the first side; the first positioning structure 121 disposed on the second side includes a base 1201 protruding from the surface of the second side and a connecting portion 1202 protruding from the base 1201 and facing away from the second side. Furthermore, in the thickness direction, the area of ​​the connecting portion 1202 is smaller than the area of ​​the base 1201. Thus, the first positioning structure 121 as a whole can position the phone back film 2, while the base 1201 can also support the phone back film 2, preventing the adhesive surface of the phone back film 2 used for attaching the phone back panel from adhering to the surfaces of the first and second sides, facilitating the separation of the phone back film 2 from the frame 1.

[0031] In some embodiments, the second positioning structure 122 disposed on the third side includes a base 1201 protruding from the surface of the third side and a connecting portion 1202 protruding from the base 1201 and facing away from the third side; and / or, the second positioning structure 122 disposed on the fourth side includes a base 1201 protruding from the surface of the fourth side and a connecting portion 1202 protruding from the base 1201 and facing away from the fourth side. Furthermore, in the thickness direction, the area of ​​the connecting portion 1202 is smaller than the area of ​​the base 1201. Thus, the second positioning structure 122 as a whole can position the phone back film 2, while the base 1201 can also support the phone back film 2, preventing the adhesive surface of the phone back film 2 used for attaching the phone back panel from adhering to the surfaces of the third and fourth sides, which facilitates the separation of the phone back film 2 from the frame 1.

[0032] In some embodiments, the first positioning structure 121 disposed on the first side includes a base 1201 protruding from the surface of the first side and a connecting portion 1202 protruding from the base 1201 and away from the first side; the first positioning structure 121 disposed on the second side includes a base 1201 protruding from the surface of the second side and a connecting portion 1202 protruding from the base 1201 and away from the second side. Meanwhile, the second positioning structure 122 disposed on the third side includes a base 1201 protruding from the surface of the third side and a connecting portion 1202 protruding from the base 1201 and away from the third side; and / or, the second positioning structure 122 disposed on the fourth side includes a base 1201 protruding from the surface of the fourth side and a connecting portion 1202 protruding from the base 1201 and away from the fourth side. In this way, each positioning structure can position the back film 2 of the phone, while the base 1201 can also support the back film 2 of the phone, so that the adhesive surface of the back film 2 used to stick the back panel of the phone will not stick to the surface of the corresponding side, which is conducive to the separation of the back film 2 of the phone and the frame 1.

[0033] Furthermore, in some embodiments, a plurality of support columns 123 are provided on the first side at intervals along the circumference. The support columns 123 are spaced apart from the first positioning structure 121 and spaced apart from the second positioning structure 122, and the dimension of the support column 123 along the thickness direction is equal to the dimension of the base 1201 along the thickness direction.

[0034] Specifically, in addition to the protruding positioning structure, the surface of the first side 12 may also have a protruding support column 123; there is also a gap between the support column 123 and the positioning structure; and the dimension of the support column 123 in the thickness direction is equal to the dimension of the base 1201 of the positioning structure in the thickness direction. Thus, when the mobile phone back film 2 is pasted, the positioning structure can realize the positioning of the mobile phone back film 2, and at the same time, the base of the positioning structure and the support column 123 can support the mobile phone back film 2. The adhesive surface of the mobile phone back film 2 used to paste the mobile phone back panel covers the support column 123. Thus, the adhesive surface of the mobile phone back film 2 can be prevented from adhering to the surface of the first side 12 of the frame 1, which can facilitate the separation of the frame 1 and the mobile phone back film 2.

[0035] Understandably, the number of support pillars 123 can be 1, 2, 3, 4, 5, 6, 7, or 8, etc., and the number of support pillars 123 on each side can be the same or different, which is not limited here. In addition, in some implementations, if there is no positioning structure on the short side of the frame 1, at least one support pillar 123 can be provided to support the back film of the mobile phone 2.

[0036] Furthermore, in some embodiments, the first positioning structure 121 extends along the length direction, and / or the second positioning structure 122 extends along the width direction.

[0037] In some embodiments, the first positioning structure 121 may extend along the length direction.

[0038] Specifically, the first side 12 of the frame 1 includes four sides, wherein the first and second sides are long sides, and the third and fourth sides are short sides. Part of the first positioning structure 121 protrudes from the surface of the first side, and part of the first positioning structure 121 protrudes from the surface of the second side. That is, the first positioning structure 121 is disposed on the long side of the frame 1. The extension direction of the first positioning structure 121 can be parallel to the long side of the frame 1, meaning the first positioning structure 121 can be elongated and parallel to the long side of the frame 1. This allows the first positioning structure 121 to be large enough to better position the phone back film 2.

[0039] In some embodiments, the second positioning structure 122 may extend along the width direction.

[0040] Specifically, the first side 12 of the frame 1 includes four sides, wherein the first and second sides are long sides, and the third and fourth sides are short sides. The second positioning structure 122 protrudes from the surface of the third side and / or the surface of the fourth side, i.e., the second positioning structure 122 is disposed on the short side of the frame 1. The extension direction of the second positioning structure 122 can be parallel to the short side of the frame 1, meaning the second positioning structure 122 can be elongated and parallel to the short side of the frame 1. This allows the second positioning structure 122 to be large enough to better achieve the positioning function of the phone back film 2.

[0041] In some embodiments, the first positioning structure 121 may extend along the length direction and the second positioning structure 122 may extend along the width direction, so that the size of the first positioning structure 121 and the size of the second positioning structure 122 are large enough to better achieve the positioning function of the mobile phone back film 2.

[0042] Understandably, in the above embodiments, it is indicated that the base 1201 and connecting portion 1202 of each positioning structure extend. In other embodiments, the base 1201 of each positioning structure may extend, while the connecting portion 1202 of the first positioning structure 121 and / or the connecting portion 1202 of the second positioning structure 122 may be a cylindrical structure protruding from the base 1201, which can also achieve the positioning function of the mobile phone back film 2. In other embodiments, the base 1201 and connecting portion 1202 may be cylinders with different diameters, which can also achieve the positioning function of the mobile phone back film 2.

[0043] Furthermore, in some embodiments, the connecting portion 1202 of the first positioning structure 121 is provided with a chamfered structure, and / or the connecting portion 1202 of the second positioning structure 122 is provided with a chamfered structure.

[0044] In some embodiments, the first positioning structure 121 extends along the length direction, and the connecting portion 1202 of the first positioning structure 121 may be provided with a chamfered structure, so that each corner of the connecting portion 1202 of the first positioning structure 121 is an arc-shaped structure, and each corner of the connecting portion 1202 of the first positioning structure 121 is smoothly provided. In this way, when connecting the mobile phone back film 2 and the mobile phone screen protector, the mobile phone back film 2 can be connected to the connecting portion 1202 of the first positioning structure 121 in a better way; or, when the mobile phone screen protector provides positioning guidance for the mobile phone back film 2 and it is necessary to separate the mobile phone screen protector and the mobile phone back film 2, the connecting portion 1202 of the first positioning structure 121 can be separated from the mobile phone back film 2 in a good way. Therefore, it can prevent the corners of the connecting portion 1202 of the first positioning structure 121 from damaging the mobile phone back film 2 and ensure the integrity of the mobile phone back film 2.

[0045] In some embodiments, the second positioning structure 122 extends along the width direction, and the connecting portion 1202 of the second positioning structure 122 may be provided with a chamfered structure, so that each corner of the connecting portion 1202 of the second positioning structure 122 is an arc-shaped structure, and each corner of the connecting portion 1202 of the second positioning structure 122 is smoothly provided. In this way, when connecting the mobile phone back film 2 and the mobile phone screen protector, the mobile phone back film 2 can be better connected to the connecting portion 1202 of the second positioning structure 122; or, when the mobile phone screen protector provides positioning guidance for the mobile phone back film 2 and it is necessary to separate the mobile phone screen protector and the mobile phone back film 2, the connecting portion 1202 of the second positioning structure 122 can be well separated from the mobile phone back film 2. Therefore, it can prevent the corners of the connecting portion 1202 of the second positioning structure 122 from damaging the mobile phone back film 2 and ensure the integrity of the mobile phone back film 2.

[0046] In some embodiments, the connecting portion 1202 of the first positioning structure 121 and the connecting portion 1202 of the second positioning structure 122 can both be provided with a chamfered structure, thereby preventing damage to the back film 2 by the corners of the connecting portion 1202 of the first positioning structure 121 and the connecting portion 1202 of the second positioning structure 122, and ensuring the integrity of the back film 2.

[0047] In some embodiments, the number of first positioning structures 121 on the first side can be 1, 2, 3, 4, 5, or 6, etc., and the number of first positioning structures 121 on the second side can be 1, 2, 3, 4, 5, or 6, etc., and the number of first positioning structures 121 on the first side and the number of first positioning structures 121 on the second side can be the same or different. Furthermore, the shapes of the first positioning structures 121 on the first side and the first positioning structures 121 on the second side can be the same or different.

[0048] In some embodiments, the number of second positioning structures 122 on the third side can be 0, 1, 2, 3, or 4, etc.; the number of second positioning structures 122 on the fourth side can be 0, 1, 2, 3, or 4, etc.; the number of second positioning structures 122 on the third side and the number of second positioning structures 122 on the fourth side can be the same or different. Furthermore, the shapes of the second positioning structures 122 on the third side and the second positioning structures 122 on the fourth side can be the same or different.

[0049] Furthermore, in some embodiments, the receiving space 11 is also provided with a plurality of limiting parts 14 that protrude from the frame 1 and are arranged at intervals along the circumference.

[0050] Specifically, a receiving space 11 is formed inside the frame 1, and a limiting part 14 protrudes from the inner sidewall of the frame 1, and the limiting parts 14 are arranged at intervals along the circumference. When the mobile phone is received in the receiving space 11, the outer periphery of the mobile phone can abut against the limiting part 14, thereby making the mobile phone stably received in the receiving space 11 by setting the limiting part 14, and preventing relative movement between the mobile phone and the frame 1 in the length and width directions.

[0051] Understandably, when applying the phone back film 2, the second side 13 of the phone screen protector and the phone screen can be placed facing a platform such as a table, and the phone back film 2 and the phone screen protector can be connected to complete the application of the phone back film 2 to the back of the phone. In this way, relative movement in the thickness direction between the phone and the frame 1 can be prevented.

[0052] Furthermore, in some embodiments, the limiting part 14 is made of a flexible material. Specifically, by setting the limiting part 14 to a flexible material, the mobile phone can be elastically connected to the frame 1, which provides cushioning protection for the mobile phone and also makes it easy to house the mobile phone in the housing space 11; in addition, a number of limiting parts 14 are arranged at intervals along the circumference, that is, there is a gap between two adjacent limiting parts 14, so the mobile phone and the frame 1 can be separated.

[0053] Furthermore, in some embodiments, the frame 1 has an annular groove 131, the opening of which faces the second side 13.

[0054] Specifically, a positioning structure protrudes from the surface of the first side 12 of the frame 1 to guide the positioning of the mobile phone back film 2, while an annular groove 131 is provided on the second side 13 of the frame 1. This can save materials, reduce material costs, reduce the weight of the frame 1, and improve convenience.

[0055] Furthermore, in some embodiments, a plurality of reinforcing ribs 132 arranged circumferentially at intervals are provided on the inner side of the annular groove 131.

[0056] Specifically, by setting reinforcing ribs 132 in the annular groove 131, the weight of the screen protector can be reduced while the structural strength of the frame 1 can be improved. This prevents the phone from affecting the structural stability of the frame 1 when it is housed in the housing space 11, thereby improving the service life of the screen protector.

[0057] Furthermore, in some embodiments, a screen protector assembly includes a mobile phone back film 2 and a screen protector applicator. The mobile phone back film 2 has a first positioning hole 21 corresponding to a first positioning structure 121 and a second positioning hole 22 corresponding to a second positioning structure 122. The mobile phone back film 2 has an adhesive surface disposed on a first side surface 12. The first positioning structure 121 is connected to the first positioning hole 21, and the second positioning structure 122 is connected to the second positioning hole 22. The adhesive surface is adhesive for attaching to the back panel of the mobile phone.

[0058] Specifically, the mobile phone back film 2 includes a central portion and an annular portion surrounding the outer periphery of the central portion. Corresponding to the first positioning structure 121 and the second positioning structure 122, the annular portion of the mobile phone back film 2 has a first positioning hole 21 and a second positioning hole 22. Furthermore, specifically, the connecting portion 1202 of the first positioning structure 121 passes through the first positioning hole 21, and the connecting portion 1202 of the second positioning structure 122 passes through the second positioning hole 22. When applying the screen protector, first place the first side 12 facing upwards and the second side 13 facing downwards; then place the phone into the receiving space 11 of the frame 1, with the back panel facing upwards and the screen facing downwards; next, place the adhesive side of the phone back film 2 towards the back panel, aligning the positioning holes and connecting parts 1202 of the phone back film 2, and fit the positioning holes onto the connecting parts 1202; at this time, the base 1201 and the support column 123 can support the annular part of the phone back film 2, and the center of the phone back film 2 is attached to the back panel of the phone; then, an external scraper can be used to scrape the center of the phone back film 2, so that the center of the phone back film 2 is completely attached to the back panel of the phone; then remove the frame 1 from the side of the phone back film 2 away from the adhesive side, i.e., the bottom side of the phone back film 2; finally, attach the annular part of the phone back film 2 to the periphery of the phone; thus, the application of the phone back film 2 is completed.

[0059] Furthermore, in some embodiments, the mobile phone back film 2 includes a central portion and an annular portion surrounding the central portion, and a first positioning hole 21 and a second positioning hole 22 are formed in the annular portion; the size of the annular portion is less than or equal to the thickness of the mobile phone.

[0060] Specifically, the annular portion of the phone back film 2 is used to adhere to the side of the phone. Therefore, the size of the annular portion cannot exceed the thickness of the phone; otherwise, the phone back film 2 will extend from the back of the phone to the side and then along the screen, affecting the aesthetics. Therefore, the size of the annular portion should be less than or equal to the thickness of the phone. Preferably, the size of the annular portion is equal to the thickness of the phone, so that the phone back film 2 can achieve adhesion and protection to the sides of the phone.

[0061] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0062] The above is a description of the technical solution provided by this utility model. For those skilled in the art, based on the idea of ​​the embodiments of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
