The folding screen obtains larger screen space by unfolding the folding screen, has good portability and functionality, is suitable for watching videos, playing games and performing multitasking, and is widely applied to point devices such as mobile phones, tablet computers, notebook computers and intelligent wearable devices.

Taking a smart phone with a folding screen as an example, the smart phone is popular due to the advantages of a large screen, portability, multifunction, innovation and the like. The current smart phone with a folding screen can be divided into three main modes of inward folding, outward folding and sliding rolling according to a folding mode. The inward folding mobile phone is characterized in that the screen is folded inwards when being folded, the design enables the mobile phone to be more compact in a folding state, meanwhile, the screen is protected from being easily collided and scratched, and durability is improved. The outward folding mobile phone means that the screen is folded outwards when being folded, and the design ensures that the unfolded large screen provides better visual experience and operation space. The sliding roll type folding mobile phone adopts a flexible screen capable of rolling, and the screen is stretched and contracted through sliding, so that the mobile phone can adjust the size of the screen according to the requirements of users, the portability of daily use can be met, and a larger screen space can be provided when the user needs.

Due to the existence of the protection frame and the pressing bar, the structure causes the screen frame to be too wide, and the visual experience of a user is affected. Meanwhile, at the round corner of the mobile phone, the pressing strip is easy to loosen, the protection film and the protection frame are in connection failure, so that the protection film is tilted, and the quality of the mobile phone is affected. In addition, to the curved surface processing at cell-phone screen edge, need all carry out curved surface processing to guard frame and layering, so make the layering can with the better laminating of guard frame for the layering can accomplish thinness, and then reduces the frame width, but this kind of processing mode need all carry out curved surface processing to the outer edge of layering and guard frame, and the degree of difficulty is great, has increased the cost of screen protection apron.

In view of this, this application embodiment provides a screen protection apron, and this screen protection apron is through designing protection frame and flexible protection film connection structure as an organic whole, omits the layering adaptively to reach and reduce the assembly loaded down with trivial details degree, improve the connection stability of protection frame and flexible protection film, and do benefit to the purpose of frame edge curved surface processing.

The screen saver cover 100 provided in this embodiment is described below with reference to fig. 1 to 5.

Fig. 1 schematically illustrates a schematic structural diagram of a screen saver cover 100 provided in some embodiments of the present application.

Referring to fig. 1, an embodiment of the present application provides a screen protection cover 100, where the screen protection cover 100 may be installed on the screen of the folded-in mobile phone as a screen protection structure. Specifically, the screen saver cover 100 includes a flexible protective film 10 and a protective frame 20.

The "flexibility" in the flexible protective film 10 of the present embodiment means that the protective film has a certain flexibility and bendability, and can be freely bent without breaking or deforming along with folding and unfolding of the screen.

The flexible protective film 10 of the present embodiment is rectangular or nearly rectangular in shape as a whole and is of a transparent structure so that the display of the folded screen is not affected after the screen protective cover 100 is mounted. The flexible protective film 10 may be a polyester film or a polymer composite material having excellent flexibility and scratch resistance, capable of effectively protecting the screen of the folding cellular phone, and having sufficient durability.

The protective frame 20 of the present embodiment is disposed around the edge of the flexible protective film 10 and forms an integral connection structure with the flexible protective film 10. The manner of integrally connecting the flexible protection film 10 and the protection frame 20 includes injection molding or hot pressing. Taking the flexible protection film 10 and the protection frame 20 as an example of an integral connection structure formed by injection molding, due to different materials, the material of the protection frame 20 and the material of the flexible protection film 10 can be injected into an injection molding machine through a nozzle, and the protection frame 20 and the flexible protection film 10 are formed by using the injection molding machine to form an integral structure, or the flexible protection film 10 is molded first, and then the protection frame 20 is injection molded on the flexible protection film 10.

In addition, the protection frame 20 of the present embodiment may be formed into a complete middle frame structure with a frame (not shown in the drawings) of other parts of the mobile phone by means of bonding, clamping or bolting, the middle frame is a frame structure for connecting two folding screens, and the protection frame 20 of the present embodiment may be made of a resin material with good injection molding capability and structural stability, such as polycarbonate or nylon.

As can be seen from the above description, the screen protecting cover plate 100 according to the embodiment of the present application designs the flexible protecting film 10 and the protecting frame 20 as an integral connection structure, and the integral connection structure has better connection stability compared with the manner of bonding and fixing the pressing strips in the related art, and when the connection stability of the flexible protecting film 10 and the protecting frame 20 is improved, the integral connection structure can adaptively omit the pressing strips for connecting the flexible protecting film 10 and the protecting frame 20, only needs to attach the screen protecting cover plate 100 to the mobile phone screen through the vacuum chamber, and does not need the steps of connecting the redundant protecting film with the protecting frame 20, mounting the pressing strips, and the like, so that the overall frame width and the complexity of assembly of the screen protecting cover plate 100 can be greatly reduced. In addition, for the folding display screen with the edge having the curved surface design requirement, only the curved surface processing is needed for the protective frame 20 during the forming, and the curved surface processing is not needed for the pressing bar and the protective frame 20, so that the processing difficulty of the screen protection cover plate 100 is reduced.

Fig. 2 schematically illustrates a partial schematic view of a screen saver cover 100 provided in some embodiments of the present application after being cut away, and fig. 3 is an enlarged view of a portion a of fig. 2.

As shown in connection with fig. 2 and 3, in some examples, the flexible protective film 10 optionally includes a first surface 11 and a second surface 12 opposite to each other, the first surface 11 being for connecting to and conforming to a display screen, and the second surface 12 being an outer surface of the mobile phone screen. Optionally, the peripheral edge of the flexible protection film 10 in this embodiment is bent to form a bending portion 13, and the bending portion 13 extends along the direction from the second surface 12 to the first surface 11, specifically, the bending portion 13 is perpendicular to the first surface 11 and the second surface 12, and the protection frame 20 and the bending portion 13 form an integral connection structure.

The dimension of the bending portion 13 along the direction from the second surface 12 to the first surface 11 in this embodiment may be 1mm-10mm, for example, the above-mentioned dimension may be 1mm, 2mm, 3mm, 5mm, 7mm, 8.5mm, 10mm, etc., and after the protective frame 20 is connected to the flexible protective film 10 by the bending portion 13 in this embodiment, the outer surface of the protective frame 20 may be lower than or equal to the second surface 12 of the flexible protective film 10, so as to improve the flatness and the aesthetic degree of the screen protecting cover 100. The presence of the bent portion 13 also facilitates the molding of the protective frame 20 of the present embodiment at the edge of the flexible protective film 10 of the present embodiment, and the material of the protective frame 20 does not affect the first surface 11 and the second surface 12 during the molding.

Since the flexible protection film 10 has a certain smoothness, in order to further improve the connection stability between the protection frame 20 and the bending portion 13, in some examples, optionally, at least one connection hole 131 is further provided in the bending portion 13, and the aperture of the connection hole 131 may be 0.1mm-10mm, for example, the aperture may be 0.1mm, 0.3mm, 0.7mm, 2mm, 5mm, or 10 mm. The shape of the connecting hole 131 may be a circular hole in the drawing, but may also be a square hole, a polygonal hole, a special-shaped hole, or the like, which is not specifically shown in the present embodiment.

The protection frame 20 of the embodiment fills the connecting hole 131 during molding, and when the protection frame 20 is molded, the part of the protection frame 20 located at the connecting hole 131 can form a limit structure tightly connected with the connecting hole 131, the shape of the limit structure is the same as that of the connecting hole 131, the connection stability of the protection frame 20 and the flexible protection film 10 can be improved through the limit structure, and the possibility that the protection frame 20 is separated from the bending part 13 of the embodiment is reduced.

Fig. 4 schematically illustrates a schematic structural diagram of the flexible protective film 10 of the screen saver cover 100 according to some embodiments of the present application after bending. In order to facilitate the display of the first avoidance gap 14 and the second avoidance gap 15, fig. 4 and fig. 5 below in this embodiment only show the flexible protection film 10, but do not show the protection frame 20.

As shown in fig. 4, in some examples, alternatively, the number of the connection holes 131 in the present embodiment may be two or more, and the plurality of connection holes 131 may be arranged at intervals along the surrounding direction of the protective frame 20 in the present embodiment, or alternatively, along the surrounding direction of the bending portion 13 in the present embodiment, and the surrounding direction of the protective frame 20 and the surrounding direction of the bending portion 13 may refer to the circumferential direction of the flexible protective film 10 in the present embodiment. The plurality of connection holes 131 may enable the protection frame 20 of the present embodiment to form a plurality of limit structures, and may further improve connection stability of the protection frame 20 and the flexible protection film 10.

The connection hole 131 of the present embodiment may be formed simultaneously with the injection molding of the flexible protection film 10 of the present embodiment by using a mold, or may be formed by punching the flexible protection film 10 after the molding, which is not limited in this embodiment.

Fig. 5 schematically illustrates a schematic structural diagram of the flexible protective film 10 of the screen saver cover 100 provided in some embodiments of the present application before bending.

As shown in fig. 5, in some examples, the flexible protection film 10 may alternatively have a first extending direction X and a second extending direction Y perpendicular to each other, and when the flexible protection film 10 of the present embodiment is rectangular, the first extending direction X may be a length direction of the flexible protection film 10 and the second extending direction Y may be a width direction of the flexible protection film 10.

The two opposite sides of the flexible protection film 10 along the first extending direction X or the two opposite sides along the second extending direction Y in this embodiment are provided with the first avoiding notches 14, compared with the consecutive bending portion 13, the bending portion 13 provided with the first avoiding notches 14 can more facilitate the folding of the flexible protection film 10 along the first extending direction X or the second extending direction Y, so as to facilitate the folding of a mobile phone with a folding screen.

When the flexible protection film 10 of the present embodiment is folded along the first extending direction X of the folding screen, the first avoiding notch 14 may be formed in the middle of two sides of the bending portion 13 in the width direction of the flexible protection film 10, for example, as can be seen from fig. 5, before the bending portion 13 is not formed, the middle of two side edges of the flexible protection film 10 in the width direction of the folding screen is provided with a notch, after the bending portion 13 is formed, the notch and the bending position of the bending portion 13 may be in the same straight line, so the first avoiding notch 14 of the present embodiment may be regarded as the notch set by the bending portion 13, or may be regarded as the notch on two sides of the middle of the edge of the flexible protection film 10 in the width direction.

When the flexible protection film 10 of the present embodiment is folded along the second extending direction Y of the folding screen, the first avoiding notch 14 may be opened in the middle of two sides of the bending portion 13 in the extending direction of the flexible protection film 10 (such an embodiment is not shown in the figure).

In the first extending direction X and the second extending direction Y in fig. 5, the bending portion 13 forms two sub-bending structures 132 on opposite sides of the flexible protection film 10, and a first avoiding notch 14 may be correspondingly provided on the sub-bending structures 132 on opposite sides in the first extending direction X or the second extending direction Y, where a depth of the first avoiding notch 14 may be greater than a width of the sub-bending structure 132 on the same side thereof, and in some examples, a depth of the first avoiding notch 14 may be 0.5-5mm, for example, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 5 mm. The width of the first relief notch 14 may be 1-10mm, such as 1mm, 3.5mm, 4mm, 6mm, 7.5mm, 10mm, etc.

In order to facilitate folding of the flexible protection film 10 of the present embodiment along the middle area of the first extending direction X, in some examples, optionally, the present embodiment designs the protection frame 20 to have a break at the first avoidance gap 14, so that the protection frame 20 of the present embodiment forms a first frame body 21 and a second frame body 22 that are approximately U-shaped, and a space between the first frame body 21 and the second frame body 22 is where the first avoidance gap 14 of the present embodiment is located.

Referring again to fig. 5, in some examples, the flexible protective film 10 of the present embodiment may optionally be provided with second relief notches 15 extending through the bent portion 13 at four opposite corners.

The shape of the second avoiding notch 15 in this embodiment may be a curved notch in the illustration, and the depth of the curved notch may be 1-10mm, however, the shape of the second avoiding notch 15 may also be rectangular or other shapes, which is not specifically described in this embodiment. When the second avoidance gap 15 in this embodiment is in a curved shape, it may specifically be in a circular arc shape, and the radius corresponding to the circular arc-shaped second avoidance gap 15 may be 0.1-10mm, for example, 0.1mm, 1mm, 3mm, 4, mm, 10mm, etc. The reason for providing the second avoidance gap 15 is that the mobile phone screen has an arc transition structure at four diagonal corners, and thus, it is necessary to adaptively avoid the four diagonal corners of the flexible protection film 10. Meanwhile, the second avoidance notch 15 is formed to facilitate bending deformation of the bending portion 13, so that the flexible protection film 10 structure in fig. 4 is formed.

In some examples, optionally, the protection frame 20 of the present embodiment is provided with a diagonal connection portion 23 located at the second avoidance gap 15, where a side of the diagonal connection portion 23 facing away from the second avoidance gap 15 is curved, so that four diagonal positions of the screen protection cover 100 can be matched with four diagonal positions of the mobile phone screen.

Referring again to fig. 3, in some examples, optionally, the protection frame 20 of the present embodiment is provided with a receiving groove 24 for receiving the bending portion 13, where the receiving groove 24 includes a first outer wall surface 241 and a second outer wall surface 242 opposite to each other, the first outer wall surface 241 is connected to the first surface 11, and the second outer wall surface 242 is smoothly connected to the second surface 12. The connection stability of the protection frame 20 and the bent portion 13 can be improved by the receiving groove 24.

Optionally, in a cross section along a direction from the first surface 11 to the second surface 12, or along a cross section of the flexible protection film 10, the second outer wall surface 242 of the present embodiment includes a curved section 2421 and a straight section 2422, one end of the curved section 2421 is connected to the second surface 12, and the other end is connected to the straight section 2422, the curved section 2421 makes the whole edge of the screen protection cover 100 have a curved surface, and the structure of the curved surface edge can not only increase the fluency and aesthetic feeling of the appearance of the mobile phone, but also provide better hand feeling for the user, and has better anti-damage capability such as anti-drop and anti-scratch.
