[0030] Currently, when applying a film to a mobile phone screen, in order to improve the film application efficiency and prevent the mobile phone film from being applied crooked, a mobile phone film application auxiliary tool is usually used for film application. The mobile phone film application auxiliary tool generally includes a housing, a positioning frame, etc. The positioning frame is used to position the mobile phone. The sizes of the housing and the positioning frame are adapted, and a plurality of cooperating limiting structures are respectively arranged inside the housing and the positioning frame, so that the positioning frame can be relatively fixed to the housing after being installed in the housing, and a limiting structure for fixing the mobile phone film is also provided. The existing mobile phone film application auxiliary tool has a relatively complex structure, a high cost, and is also relatively inconvenient to operate. Bubbles are easily generated during the film application process, and further treatment of the bubbles is required, which affects the film application efficiency.

[0031] The present utility model provides a mobile phone film application auxiliary device, which has a simple structure, is convenient to manufacture, can improve the efficiency of mobile phone film application, and also reduces the difficulty and equipment cost of mobile phone film application.

[0032] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the mobile phone film application auxiliary device 10 includes a positioning frame 100 and a flexible pressure maintaining member 200. The positioning frame 100 is provided with a positioning groove 150 for the mobile phone to be placed in. The positioning frame 100 has opposite front faces 100a and back faces 100b; the flexible pressure maintaining member 200 includes an outer frame 210 and flexible pressure maintaining strips 220. The frame edges of the outer frame 210 are correspondingly connected to the back faces 100b of the frame edges of the positioning frame 100. The outer frame 210 includes two relatively arranged long sides 211 and two relatively arranged short sides 212. The two ends of the long side 211 are respectively connected to the ends of the two short sides 212, and the flexible pressure maintaining strips 220 connect the two short sides 212.

[0033] Specifically, the positioning frame 100 is in a frame shape and forms a positioning slot 150 for placing a mobile phone. The material of the positioning frame 100 is a hard plastic material, which is not easily deformed and has a low cost. The shape and size of the positioning slot 150 are adapted to the mobile phone. According to different models and sizes of mobile phones, the shape and size of the positioning slot 150 can be adapted and adjusted. The positioning frame 100 has opposite front surface 100a and back surface 100b. It should be noted that the front surface 100a refers to the side of the positioning frame 100 facing the user when the user uses the mobile phone film applying auxiliary device 10 (i.e., the front side of the positioning frame 100), and the back surface 100b refers to the other side opposite to the front surface 100a (i.e., the back side of the positioning frame 100).

[0034] Please refer to Figure 2 , a flexible pressure maintaining member 200 is connected to the back surface 100b of the positioning frame 100. The flexible pressure maintaining member 200 includes an outer frame 210 and flexible pressure maintaining strips 220. The shape of the outer frame 210 is generally adapted to the shape of the positioning frame 100, and the frame edges of the two are correspondingly connected together. Therefore, correspondingly, the outer frame 210 includes two relatively arranged long sides 211 and two relatively arranged short sides 212. The long sides 211, short sides 212, long sides 211, and short sides 212 are connected end to end in sequence and are generally in a rectangular shape. The two ends of the flexible pressure maintaining strip 220 are respectively connected to the two short sides 212. When the user uses the mobile phone film applying auxiliary device 10, that is, when the mobile phone is placed in the positioning slot 150, the flexible pressure maintaining strip 220 can abut against the mobile phone film and play a supporting role for the mobile phone.

[0035] The mobile phone film usually includes at least two layers of film, a surface film and a bottom film. When the user applies the film, the surface film needs to be torn off and the bottom film needs to be pasted onto the mobile phone screen. The using method of the mobile phone film applying auxiliary device 10 of the present utility model is specifically as follows:

[0036] First, tear off the surface film of the mobile phone film, and place the sticky side of the bottom film (i.e., the side separated from the surface film) facing the front side of the positioning frame 100 into the positioning slot 150. The positioning slot 150 is adapted to the size of the bottom film, and the four wall surfaces of the positioning slot 150 will limit the position of the bottom film. Then, place the mobile phone with a clean screen and no film on the screen, with its mobile phone screen facing the bottom film, into the positioning slot 150, and press the mobile phone into the positioning frame 100 (i.e., the back side of the positioning frame 100) so that the bottom film fits with the mobile phone screen, completing the mobile phone film application. This film application method is simple, efficient, and there is no complicated positioning structure that requires re-positioning the mobile phone film and the mobile phone again, improving the user's film application efficiency and reducing the user's film application difficulty. Moreover, the mobile phone film applying auxiliary device 10 has a simple structure and is convenient to manufacture, further reducing the production cost and labor cost of the mobile phone film applying auxiliary device 10.

[0037] It is worth mentioning that when the user applies a film to the mobile phone, the user presses the mobile phone into the positioning frame 100. At this time, the flexible pressure-holding strip 220 abuts against the mobile phone screen, and the area where the mobile phone screen abuts against the flexible pressure-holding strip 220 is stressed, so that the bottom film can be pressed tightly against the mobile phone screen, thereby realizing the automatic fitting of the bottom film and the mobile phone screen.

[0038] The outer frame 210 and the flexible pressure-holding strip 220 are integrally formed. Specifically, the outer frame 210 and the flexible pressure-holding strip 220 are integrally formed. The outer frame 210 is directly connected to the back surface 100b of the frame edge of the positioning frame 100 to ensure their relative fixation, so as to realize the connection of the whole flexible pressure-holding member 200 with the positioning frame 100. This not only saves time and improves production efficiency, but also reduces production costs. Moreover, the integral forming technology is often combined with automated production equipment, further improving the production efficiency and consistency of the flexible pressure-holding member 200. The integral forming setting also has significant advantages in terms of cost reduction. On the one hand, integral forming reduces material waste caused by cutting, waste, etc., reducing the raw material cost; on the other hand, due to the reduction of processes and the improvement of automation degree, integral forming also reduces the dependence on labor and labor costs.

[0039] Please refer to Figure 4 and Figure 5 As shown in and, the mobile phone film applying auxiliary device 10 of the present utility model includes a positioning frame 100 and a flexible pressure-holding member 200. The positioning frame 100 is provided with a positioning groove 150 for placing the mobile phone. The flexible pressure-holding member 200 includes an outer frame 210 and a flexible pressure-holding strip 220. The frame edge of the outer frame 210 is correspondingly connected to the back surface 100b of the frame edge of the positioning frame 100. The outer frame 210 includes two relatively arranged long sides 211 and two relatively arranged short sides 212. The two ends of the long side 211 are respectively connected to the ends of the two short sides 212, and the flexible pressure-holding strip 220 connects the two short sides 212. The mobile phone film applying auxiliary device 10 of the present utility model limits the mobile phone and the mobile phone film by using the positioning groove 150 of the positioning frame 100. When the user presses the mobile phone during film application, the flexible pressure-holding strip 220 applies an external force to the area where the mobile phone screen abuts against the flexible pressure-holding strip 220, so that the bottom film can be pressed tightly against the mobile phone screen, thereby realizing the automatic fitting of the bottom film and the mobile phone screen without bubbles. The mobile phone film applying auxiliary device 10 has a simple structure and is convenient to manufacture, further reducing the production cost and labor cost of the mobile phone film applying auxiliary device 10, and is also convenient to use, further improving the efficiency of mobile phone film application.

[0040] In an embodiment, the flexible pressure-holding member 200 and the positioning frame 100 are bonded. Specifically, the flexible pressure-holding member 200 and the positioning frame 100 are bonded into one body to prevent their relative separation during mobile phone film application. At the same time, the bonding method is simple to operate.

[0041] In one embodiment, the flexible pressure-holding member 200 is made of foam. The foam has good elasticity, is lightweight, can be quickly pressure-sensitive fixed, is convenient to use, bends freely, and has an ultra-thin volume. Moreover, the cost of the foam is low, which further reduces the production cost.

[0042] Please refer to Figures 2 to 4 , in one embodiment, the mobile phone film-applying auxiliary device 10 further includes a bottom plate 300, and the flexible pressure-holding member 200 is connected to the bottom plate 300. Specifically, the bottom plate 300 and the flexible pressure-holding member 200 can be connected by gluing, which is convenient and fast and has a low cost. Since the flexible pressure-holding member 200 is made of a flexible material, when the mobile phone is placed in the positioning frame 100 and pressed downwards, the flexible pressure-holding strip 220 may be broken. At the same time, in order to provide support for the flexible pressure-holding strip 220 during use, the mobile phone film-applying auxiliary device 10 further includes a bottom plate 300, and the flexible pressure-holding member 200 is connected to the bottom plate 300. Further, the material of the bottom plate 300 is set as cardboard, and the cost is relatively low.

[0043] Please refer to Figure 1 and Figure 2 , in one embodiment, the mobile phone film-applying auxiliary device 10 further includes a face shell 400. The face shell 400 and the bottom plate 300 are connected by a connecting member 500, and the face shell 400 can be rotatably covered on the front surface 100a of the positioning frame 100 relative to the bottom plate 300. Specifically, the face shell 400 is used to cover the front surface 100a of the positioning frame 100, and plays a role in protecting the positioning frame 100 and the flexible pressure-holding member 200, preventing the mobile phone film-applying auxiliary device 10 from being damaged during transportation. During use, the face shell 400 can be rotated and opened. The face shell 400, the bottom plate 300 and the connecting member 500 can be integrally formed, which is convenient for production, can improve production efficiency, and further reduces the production cost.

[0044] Please refer to Figures 2 to 4 , in one embodiment, the flexible pressure-holding strip 220 is located in the middle of the flexible pressure-holding member 200. With such a setting, when the user applies a film to the mobile phone, the flexible pressure-holding strip 220 can abut against the middle of the mobile phone screen and apply an external force to the middle of the mobile phone screen, so that the middle of the mobile phone screen is attached to the bottom film, and the attachment of the mobile phone screen and the bottom film is gradually completed from the middle to both sides of the mobile phone screen. The middle refers to the width direction of the flexible pressure-holding member 200, near the symmetry axis of its width.

[0045] Please refer to Figure 4, in one embodiment, the width of the flexible pressure maintaining strip 220 is 0.8 cm - 1.5 cm, and / or the thickness of the flexible pressure maintaining member 200 is 1 mm - 5 mm. To ensure that when applying a film to a mobile phone, the flexible pressure maintaining strip 220 can apply a suitable external force to the mobile phone screen, the width of the flexible pressure maintaining strip 220 is limited to be between 0.8 cm and 1.5 cm. The width of the flexible pressure maintaining strip 220 can exemplarily be 0.8 cm, 0.9 cm, 1.0 cm, 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm. Similarly, to avoid the excessive thickness of the flexible pressure maintaining member 200 affecting the thickness of the entire mobile phone film applying auxiliary device 10 or affecting the effect of the flexible pressure maintaining strip 220 in the flexible pressure maintaining member 200 applying a force to the mobile phone screen, and also to avoid the excessive thinness of the flexible pressure maintaining member 200 causing the flexible pressure maintaining member 200 to be easily damaged and the flexible pressure maintaining strip 220 to be easily broken, the thickness of the flexible pressure maintaining member 200 is limited to be between 1 mm and 5 mm. The thickness of the flexible pressure maintaining member 200 can exemplarily be 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm. At the same time, it should also be noted that if the flexible pressure maintaining member 200 is too thin, when the user applies a film to the mobile phone, the reverse force applied by the flexible pressure maintaining member 200 to the mobile phone screen is too small, which will cause the edges of the mobile phone screen and the mobile phone film to be first attached, resulting in bubbles in the mobile phone. On the other hand, if the flexible pressure maintaining member 200 is too thick, when the user applies a film to the mobile phone, the too thick flexible pressure maintaining member 200 supports the mobile phone film, making the distance between the mobile phone film and the bottom plate 300 too large, which will cause the mobile phone film to tilt too much in the horizontal direction during the film applying process by the user, resulting in the mobile phone film being applied crooked.

[0046] Please refer to Figure 4 and Figure 5 , in one embodiment, the positioning frame 100 has opposite first frame edges 110, second frame edges 120, and third frame edges 130 and fourth frame edges 140 that are connected to the first frame edges 110 and the second frame edges 120 and are oppositely arranged. The first frame edges 110, third frame edges 130, second frame edges 120, and fourth frame edges 140 are sequentially connected to enclose a positioning slot 150 for placing a mobile phone. Among them, the inner wall surfaces of the first frame edges 110 and the second frame edges 120 are provided with avoidance slots 160 for avoiding the function keys of the mobile phone; and / or, the inner wall surfaces of the third frame edges 130 and / or the fourth frame edges 140 are provided with finger grooves 170.

[0047] Specifically, the positioning frame 100 has a first frame edge 110, a second frame edge 120, a third frame edge 130, and a fourth frame edge 140. The back surface 100b of the first frame edge 110, the second frame edge 120, the third frame edge 130, and the fourth frame edge 140 is connected to the outer frame 210 of the flexible pressure maintaining member 200. The first frame edge 110 and the second frame edge 120 are long frame edges, and the third frame edge 130 and the fourth frame edge 140 are short frame edges. Avoidance grooves 160 for avoiding the function keys of the mobile phone are provided on the first frame edge 110 and the second frame edge 120, so as to avoid the function keys of the mobile phone after the mobile phone is placed in the positioning groove 150. The opening positions of the avoidance grooves 160 correspond to the positions of the function keys of the mobile phone adapted to the positioning frame 100.

[0048] Meanwhile, a finger groove 170 can be provided on the third frame edge 130 or the fourth frame edge 140 to facilitate the user to take out the mobile phone from the positioning groove 150 after the mobile phone film is pasted. The finger groove 170 can be provided only on the third frame edge 130, or only on the fourth frame edge 140, or can be provided on both the third frame edge 130 and the fourth frame edge 140. Preferably, finger grooves 170 are provided on both the third frame edge 130 and the fourth frame edge 140. Further, the avoidance position formed by the finger groove 170 can also be used for pasting and positioning the mobile phone film, that is, the upper and lower sides of the mobile phone film are pasted on the outer frame 210, and the avoidance position formed by the finger groove 170 is used to avoid the pasting position of the mobile phone film to further fix the position of the mobile phone film in the positioning groove 150. The positioning method adopted can be to provide a pasting and positioning film layer on the side of the bottom film of the mobile phone film facing away from the surface film. The upper and lower sides of this film layer have pasting areas protruding from the bottom film, and the pasting areas are pasted on the outer frame 210. The avoidance position formed by the finger groove 170 is used to avoid the pasting areas.

[0049] The above is only an exemplary embodiment of the present invention, and thus does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
