[0044] Figure 1 A schematic diagram of a foldable mobile phone with a foldable screen is provided for related technologies. Figure 2 A schematic diagram of the structure of a foldable mobile phone with a foldable screen provided for related technology, see Figure 1 and Figure 2 . In the related art, a foldable mobile phone with a foldable screen is provided, and the foldable mobile phone includes an existing first body 01, an existing second body 02, an existing hinge structure 03 and an existing flexible screen 04. The existing hinge structure 03 connects the existing first body 01 and the existing second body 02 respectively, and both the existing first body 01 and the existing second body 02 can rotate around the hinge of the existing hinge structure 03, thereby realizing the bending of the foldable mobile phone. When the foldable mobile phone is in a flattened state, the existing flexible screen 04 is arranged above the existing first body 01, the existing hinge structure 03 and the existing second body 02. The existing hinge structure 03 includes a plurality of rigid screen-supporting bodies, and the cross-section of the rigid screen-supporting bodies is fan-shaped. When the foldable mobile phone with a foldable screen is in a folded state, the plurality of rigid screen-supporting bodies of the existing hinge structure 03 are rolled up and combined, so that the cross-section thereof is combined into a semicircular shape. The combined rigid screen-supporting bodies can support the existing flexible screen 04 of the foldable mobile phone in the folded state. When the screen-folding, bendable phone is in the flattened state, the multiple rigid screen-supporting bodies of the existing hinge structure 03 are arranged in sequence, with the curved surfaces of the rigid screen-supporting bodies supporting the existing flexible screen 04. Since the screen-folding, bendable phone needs to maintain the same length as the rigid screen-supporting bodies in both the flattened and folded states, and the length of the existing flexible screen 04 remains unchanged, it is necessary to stretch the screen-supporting area composed of the multiple rigid screen-supporting bodies when the screen-folding, bendable phone is in the flattened state so that the length of the screen-supporting area matches the length of the screen. Therefore, it is necessary to evenly arrange the multiple rigid screen-supporting bodies when the screen is in the flattened state, creating unsupported grooves 031 between the multiple rigid screen-supporting bodies to meet the length requirement. As a result, due to the curved surface of the rigid screen-supporting bodies and the grooves 031 between the multiple rigid screen-supporting bodies, the existing flexible screen 04 covering the multiple rigid screen-supporting bodies cannot be properly supported in the screen-supporting area. The existing flexible screen 04 covering the screen-supporting area will partially sag, which is not conducive to viewing. At the same time, when the user uses the touch function of the existing flexible screen 04, there will be obvious unevenness when the user slides the finger on the existing flexible screen 04. Such a design brings a poor user experience to the user.
[0045] In response to the above problems, an embodiment of the present invention provides an electronic device with a foldable screen. The electronic device with a foldable screen provided in the embodiment of the present application can be a mobile phone, a tablet computer, a personal digital assistant (PDA), a car computer, a smart wearable device, a smart home device, etc. The embodiment of the present application does not specifically limit the specific form of the above electronic devices.
[0046] Figure 3 This is a structural diagram of a mobile phone display panel side provided in an embodiment of the present application. Figure 4 This is a structural diagram of the back cover side of a mobile phone provided in an embodiment of the present application, see Figure 3 and Figure 4 The mobile phone 100 includes a first middle frame 1, a second middle frame 2, a first rear shell (not shown in the figure), a second rear shell (not shown in the figure), a flexible display panel (not shown in the figure), and a hinge 3. The first and second rear shells are both arranged opposite to a portion of the flexible display panel, with the first middle frame 1 located between the first rear shell and the flexible display panel, and the second middle frame 2 located between the second rear shell and the flexible display panel. The two sides of the hinge 3 are connected to the first and second middle frames 1 and 2 respectively, so that the first and second middle frames 1 and 2 can both rotate around the hinge 3, thereby realizing the expansion and closure of the mobile phone. The first middle frame 1, the second middle frame 2, the hinge 3, the first rear shell, the second rear shell, and the flexible display panel can form a housing. The housing cavity is provided with a motherboard, a battery, and a retaining wall (not shown in the figure) for fixing the battery. A processor and a memory are provided on the motherboard. The memory is used to store computer program code. The computer program code includes computer instructions. The processor is used to call computer instructions to enable the mobile phone 100 to perform corresponding operations.
[0047] The materials of the first and second rear covers may include, for example, opaque materials such as plastic, plain leather, and fiberglass; or translucent materials such as glass. The present embodiment does not limit the materials of the first and second rear covers.
[0048] Flexible display panels include, for example, organic light emitting diode (OLED) display panels and LED display panels, among which LED display panels include, for example, micro-LED display panels and mini-LED display panels. The embodiments of this application do not limit the type of flexible display panel; any flexible and bendable display panel can be used as the flexible display panel in the embodiments.
[0049] The specific structure of the rotating shaft 3 is described below.
[0050] Figure 5 This is a schematic diagram of a structure including a flexible screen-supporting structure provided in an embodiment of the present application, wherein the rotating shaft faces the display panel. Figure 6 This is a schematic diagram of the structure of a flexible screen support structure facing the shaft provided in an embodiment of the present application. Figure 7 This is a schematic diagram of a structure provided by an embodiment of the present application with a rotating shaft facing the rear cover side. Figure 8 This is an enlarged schematic diagram of area A provided in an embodiment of the present application. Figure 9 This is an exploded view of an embodiment of the present application with the shaft facing the rear cover. Figure 10 This is a schematic diagram of a structure provided by an embodiment of the present application, in which the rotating shaft does not include a flexible screen supporting structure and faces the display panel. Figure 11 This is an exploded view of the embodiment of the present application with the shaft facing the display panel. Figures 5 to 11 The rotating shaft 3 includes a shaft body 31, a flexible screen-supporting structure 35 located between the shaft body 31 and the flexible display panel, and a first door panel 32 and a second door panel 33 located on either side of the shaft body 31, respectively. The first door panel 32 is connected to the first middle frame 1, and the second door panel 33 is connected to the second middle frame 2. The rotating shaft 3 also includes a swing arm 34, and the first door panel 32 and the second door panel 33 are both connected to the shaft body 31 through the swing arm 34. The swing arm 34 can rotate around the shaft body 31, thereby driving the first door panel 32 and the second door panel 33 to rotate around the shaft body 31, thereby achieving flattening and overlapping of the first door panel 32 and the second door panel 33. The type and number of the swing arms 34 can be set according to actual needs. For example, the swing arm 34 includes a main swing arm 341, a secondary swing arm 342, and a synchronous swing arm 343. Under the joint action of the main swing arm 341 and the secondary swing arm 342, the first door panel 32 and the second door panel 33 can rotate around the shaft body 31. Under the action of the synchronization arm 343, the first door panel 32 and the second door panel 33 rotate synchronously with respect to the shaft 31. The side of the swing arm 34 facing the flexible display panel is provided with a swing arm support portion 340. The mobile phone also includes a flexible screen support structure 35, which is disposed between the swing arm support portion 340 and the flexible display panel. Figure 12 This is a flattened cross-sectional view of a rotating shaft at the main swing arm provided in an embodiment of the present application. Figure 13 This is a cross-sectional view of a rotating shaft at the main swing arm provided in an embodiment of the present application, see Figure 12 and Figure 13 . Exemplarily, a main swing arm support portion 3401 is provided on the side of the main swing arm 341 facing the flexible display panel. The side of the main swing arm support portion 3401 facing the flexible display panel is in the shape of an arc surface, and the arc surface protrudes toward the side close to the flexible display panel. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in a flattened state, the flexible display panel and the flexible screen-supporting structure 35 opposite to the area where the rotating shaft 3 are located are unfolded into a plane, and the arc surface of the main swing arm support portion 3401 is in line contact with the flexible screen-supporting structure 35. The main swing arm support portion 3401 can support the flexible screen-supporting structure 35 and prevent the flexible screen-supporting structure 35 from being concave. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in a superimposed state, the flexible display panel opposite to the area where the rotating shaft 3 is located is curled into an arc surface, and the arc surface of the main swing arm support portion 3401 is attached to the flexible screen-supporting structure 35 to support the flexible screen-supporting structure 35 and provide sufficient support for the flexible display panel. Figure 14 This is a flattened cross-sectional view of a rotating shaft at the auxiliary swing arm provided in an embodiment of the present application, see Figure 14. A secondary swing arm support portion 3402 is provided on the side of the secondary swing arm 342 facing the flexible display panel. The shape of the side of the secondary swing arm support portion 3402 facing the flexible display panel can be determined according to actual needs. For example, the shape of the side of the secondary swing arm support portion 3402 facing the flexible display panel can be a plane. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in a flattened state, the flexible display panel and the flexible screen support structure 35 opposite to the area where the rotating shaft 3 are located are unfolded into a plane, and the plane of the secondary swing arm support portion 3402 is in surface contact with the flexible screen support structure 35. The secondary swing arm support portion 3402 supports the flexible screen support structure 35 to prevent the flexible screen support structure 35 from sinking. In the process of the first door panel 32 and the second door panel 33 of the rotating shaft 3 changing from a flattened state to a superimposed state, the secondary swing arm 342 partially retracts into the first door panel 32 and the second door panel 33 in a direction away from the shaft body 31 while rotating, and the secondary swing arm support portion 3402 moves toward the first door panel 32 and the second door panel 33. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in the overlapping state, only the main swing arm support part 3401 supports the flexible screen support structure 35 with an arc-shaped curved area, and the auxiliary swing arm support part 3402 does not support the part of the flexible screen support structure 35 with an arc-shaped curved area. Figure 15 This is a flattened cross-sectional view of a rotating shaft at a synchronous swing arm provided in an embodiment of the present application, see Figure 15. A synchronous swing arm support portion 3403 is provided on the side of the synchronous swing arm 343 facing the flexible display panel. The shape of the side of the synchronous swing arm support portion 3403 facing the flexible display panel can be determined according to actual needs. For example, the shape of the side of the synchronous swing arm support portion 3403 facing the flexible display panel can be a plane. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in a flattened state, the flexible display panel and the flexible screen support structure 35 opposite to the area where the rotating shaft 3 are located are unfolded into a plane, and the plane of the synchronous swing arm support portion 3403 is in surface contact with the flexible screen support structure 35. The synchronous swing arm support portion 3403 supports the flexible screen support structure 35 to prevent the flexible screen support structure 35 from sinking. In the process of the first door panel 32 and the second door panel 33 of the rotating shaft 3 changing from a flattened state to a superimposed state, the synchronous swing arm partially retracts into the first door panel 32 and the second door panel 33 in a direction away from the shaft body 31 while rotating, and the synchronous swing arm support portion 3403 moves toward the first door panel 32 and the second door panel 33. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in the overlapped state, only the main swing arm support portion 3401 supports the curved portion of the flexible screen-supporting structure 35, while the synchronous swing arm support portion 3403 does not support the curved portion of the flexible screen-supporting structure 35. Of course, the above embodiment is merely an example. In actual implementation, the shapes of the main swing arm support portion 3401, the auxiliary swing arm support portion 3402, and the surface of the synchronous swing arm support portion 3403 facing the flexible display panel can be further configured according to actual needs. For example, the surfaces of the auxiliary swing arm support portion 3402 and the synchronous swing arm support portion 3403 facing the flexible display panel can both be configured as curved surfaces.
[0051] Continue to see Figure 5 、 Figure 6 、 Figure 9 and Figure 11The flexible screen support structure 35 may include a flexible screen support body 351. The flexible screen support body 351 includes a first surface and a second surface facing each other. The first surface is divided into a first area near the first door panel 32 and a second area near the second door panel 33. The first surface may face the flexible display panel. The flexible screen support structure 35 may also include a first rigid reinforcement sheet 352 and a first flexible reinforcement sheet 353 bonded to the first area, and a second rigid reinforcement sheet 354 and a second flexible reinforcement sheet 355 bonded to the second area. The first rigid reinforcement sheet 352 is located on the side of the first flexible reinforcement sheet 353 away from the second area, and the second rigid reinforcement sheet 354 is located on the side of the second flexible reinforcement sheet 355 away from the first area. A groove area 356 is provided between the first flexible reinforcement sheet 353 and the second flexible reinforcement sheet 355, spanning the first and second areas. The groove area 356 is free of the aforementioned reinforcement sheet. Because the flexible screen support structure 35 in the groove area 356 is free of the aforementioned reinforcement sheet, it is relatively flexible and easy to bend, facilitating the transition of the flexible screen support structure 35 between the flattened and folded states. The first and second flexible reinforcement sheets 353 and 355 serve as flexible reinforcement sheets for the flexible screen support body 351, enhancing the deformation resistance of the flexible screen support body 351. Therefore, the supporting force provided to the flexible screen support body 351 by the main swing arm support portion 3401, the auxiliary swing arm support portion 3402, and the synchronous swing arm support portion 3403 can be evenly distributed to various areas of the flexible screen support body 351, thereby preventing the flexible screen support body 351 from being too soft, resulting in bulges in the corresponding portions of the main swing arm support portion 3401, the auxiliary swing arm support portion 3402, and the synchronous swing arm support portion 3403. In the projection direction perpendicular to the extension plane of the first rigid reinforcement sheet 352, the projection of the first rigid reinforcement sheet 352 falls on the first door panel 32. In the projection direction perpendicular to the extension plane of the second rigid reinforcement sheet 354, the projection of the second rigid reinforcement sheet 354 falls on the second door panel 33. The first rigid reinforcement sheet 352 and the second rigid reinforcement sheet 354 are both rigid components, so the flexible screen support body 351 connected to them cannot deform. This design ensures that the flexible screen support body 351 has both rigid and flexible parts, and also allows the rigid and flexible parts to be naturally combined.
[0052] Figure 16 This is a structural diagram of a flexible screen support structure provided in an embodiment of the present application, see Figure 16. The flexible screen support structure 35 also includes an elastic sliding assembly for movably connecting the edge of the flexible screen support structure 35 to the first door panel 32 or the second door panel 33. The present invention is not limited to the specific composition of the elastic sliding assembly. Exemplarily, the elastic sliding assembly includes a slider 357 and a spring 358, and a slider 357 is provided at the edge of the first area away from the second area, and at the edge of the second area away from the first area. The slider 357 is connected to the first rigid reinforcement plate 352 and the second rigid reinforcement plate 354 through the window of the flexible screen support body 351. The slider 357 includes a slider body 3571, a first sub-slider 3572 and a second sub-slider 3573 located on both sides of the slider body 3571, and a slider spring connecting column 3574 connected to the slider body 3571. The extension direction of the slider spring connecting column 3574 is parallel to the width direction of the mobile phone, and the extension direction is the direction approaching the shaft body 31. Figure 17 A schematic diagram of a gap structure provided in an embodiment of the present application is shown in FIG. Figure 17A notch 359 is provided on the edges of the first and second door panels 32 and 33 away from the shaft body 31. The notch 359 includes a first side wall 3591, a second side wall 3592, and a bottom wall 3593. A first slide groove 35911 is provided on the first side wall 3591. The first slide groove 35911 may be perpendicular to the first side wall 3591 and extend from the opening of the notch 359 to the bottom wall 3593. A second slide groove 35921 is provided on the second side wall 3592. The second slide groove 35921 may be perpendicular to the second side wall 3592 and extend from the opening of the notch 359 to the bottom wall 3593. A door panel spring connecting column 3594 is provided near the bottom wall 3593, corresponding to the position of the slider spring connecting column 3574. The slider body 3571 can be inserted into the notch 359 from the opening of the notch 359. At the same time, the first sub-slider 3572 is inserted into the first slide groove 35911, and the second sub-slider 3573 is inserted into the second slide groove 35921. The two ends of the spring 358 are respectively mounted on the slider spring connecting column 3574 and the door panel spring connecting column 3594. Since the foldable mobile phone with an outward-folding screen needs to keep the flexible display panel from being stretched or compressed in both the flattened state and the folded state, the length of the flexible display panel remains unchanged. Therefore, when the mobile phone is transformed from the folded state to the flattened state, the first door panel 32 and the second door panel 33 respectively stretch the flexible screen support structure 35 to both sides. When the flexible screen support structure 35 is stretched, the spring 358 is compressed, and the parts of the first door panel 32 and the second door panel 33 covered by the flexible screen support structure 35 are exposed, thereby solving the problem of insufficient length of the flexible screen support structure 35. During the process of the mobile phone changing from a flattened state to a folded state, the force of the first door panel 32 and the second door panel 33 pulling the flexible screen support structure 35 toward both sides is reduced, and the compressed spring 358 is gradually released. The flexible screen support structure 35 covers more of the first door panel 32 and the second door panel 33. The flexible screen support body 351, the first flexible reinforcement sheet 353 and the second flexible reinforcement sheet 355 can be soft plastic sheets, and the first rigid reinforcement sheet 352 and the second rigid reinforcement sheet 354 can be steel sheets. The flexible screen support body 351 and the first flexible reinforcement sheet 353, the second flexible reinforcement sheet 355, the first rigid reinforcement sheet 352 and the second rigid reinforcement sheet 354 can be connected by gluing. The slider 357 can be made of metal, and the connection between the slider 357 and the first rigid reinforcement sheet 352, and the connection between the slider 357 and the second rigid reinforcement sheet 354 can be connected by welding.
[0053] Of course, the above embodiment only exemplifies the composition and setting method of the flexible screen support structure. In fact, any flexible screen support structure that does not deviate from the main purpose of the present invention is acceptable, and the embodiments of the present application do not limit the composition and setting method of the flexible screen support structure. For example, the slider 357 and the spring 358 can be omitted, and the notch 359 is not set on the edges of the first door panel 32 and the second door panel 33. The first rigid reinforcement sheet 352 is directly fixedly connected to the first door panel 32, and the second rigid reinforcement sheet 354 is directly fixedly connected to the second door panel 33. The flexible screen support body 351 is an elastic component. When the first door panel 32 and the second door panel 33 change between the flattened state and the overlapping state, the flexible screen support body 351 is stretched and released. On this basis, a first rigid reinforcement sheet 352 and a second rigid reinforcement sheet 354 can be set, and the first rigid reinforcement sheet 352 is fixedly connected to the first door panel 32, and the second rigid reinforcement sheet 354 is fixedly connected to the second door panel 33. Alternatively, the first rigid reinforcement sheet 352 and the second rigid reinforcement sheet 354 may be omitted, and the flexible screen support body 351 may be directly connected between the first door panel 32 and the second door panel 33. In other embodiments, the first flexible reinforcement sheet 353 and the second flexible reinforcement sheet 355 may be omitted. In other embodiments, the first flexible reinforcement sheet 353 and the second flexible reinforcement sheet 355 may be omitted, and the flexible screen support body 351 may be designed to have different thicknesses at different locations, with the locations where the first flexible reinforcement sheet 353 and the second flexible reinforcement sheet 355 were originally provided being thickened.
