Fig. 1 is a schematic structural diagram of a foldable mobile phone with a foldable screen according to the related art, and fig. 2 is a schematic structural diagram of a periphery of a rotating shaft of a foldable mobile phone with a foldable screen according to the related art, see fig. 1 and fig. 2. In the related art, there is provided a screen-folding foldable mobile phone including an existing first body 01, an existing second body 02, an existing hinge structure 03, and an existing flexible screen 04. The existing rotating shaft structure 03 is respectively connected with the existing first machine body 01 and the existing second machine body 02, and the existing first machine body 01 and the existing second machine body 02 can rotate around the rotating shaft of the existing rotating shaft structure 03, so that the mobile phone can be bent. When the bendable mobile phone is in a flattened state, the existing flexible screen 04 is arranged above the existing first body 01, the existing rotating shaft structure 03 and the existing second body 02. The existing rotating shaft structure 03 comprises a plurality of rigid supporting screen bodies, and the cross sections of the rigid supporting screen bodies are fan-shaped. When the mobile phone with the foldable and foldable screen is in a folded state, the plurality of rigid screen supporting bodies of the existing rotating shaft structure 03 are curled and combined, so that the cross sections of the rigid screen supporting bodies are combined into a semicircle. The combined rigid support screen body can support the existing flexible screen 04 of the folded bendable mobile phone. When the mobile phone with the foldable screen is in a flattened state, the plurality of rigid supporting screen bodies of the existing rotating shaft structure 03 are sequentially arranged, and the cambered surfaces of the rigid supporting screen bodies support the existing flexible screen 04. Because the mobile phone with the foldable and bendable screen is required to keep the length of the existing flexible screen 04 equal to that of the rigid support screen body in the flattened state and the folded state, and the length of the existing flexible screen 04 is kept unchanged. Therefore, when the foldable mobile phone is in a flattened state, the screen support area formed by the plurality of rigid support screen bodies is stretched, so that the length of the screen support area is matched with the length of the screen. Therefore, when the screen is in a flattened state, the plurality of rigid supporting screen bodies are uniformly arranged, so that the gaps 031 without any supporting objects are generated among the plurality of rigid supporting screen bodies, and the length requirement is met. In this way, the existing flexible screen 04 covered over the plurality of rigid support panels cannot be well supported in the screen support area due to the arc shape of the surface of the rigid support panels and the gaps 031 existing between the plurality of rigid support panels. The existing flexible screen 04 covered in the screen supporting area has the problem of partial depression, which is unfavorable for viewing the video. Meanwhile, when the user uses the touch function of the existing flexible screen 04 and the finger slides on the existing flexible screen 04, the user has obvious uneven feeling. Such a design gives a poor use experience for the user.
In view of the above problems, an embodiment of the present application provides an electronic device with a foldable screen, where the electronic device with a foldable screen may be a mobile phone, a tablet pc, a Personal Digital Assistant (PDA), a vehicle-mounted computer, an intelligent wearable device, an intelligent home device, etc., and the embodiment of the present application does not limit the specific form of the electronic device.

The rotating shaft 3 comprises a shaft body 31, a flexible screen supporting structure 35 positioned between the shaft body 31 and the flexible display panel, and a first door plate 32 and a second door plate 33 respectively positioned at two sides of the shaft body 31, wherein the first door plate 32 is connected with the first middle frame 1, and the second door plate 33 is connected with the second middle frame 2. The rotating shaft 3 further comprises a swing arm 34, and the first door plate 32 and the second door plate 33 are connected with the shaft body 31 through the swing arm 34. The swing arm 34 can rotate around the shaft body 31, so that the first door plate 32 and the second door plate 33 are driven to rotate around the shaft body 31, and flattening and folding of the first door plate 32 and the second door plate 33 are achieved. The types and the number of the swing arms 34 can be set according to actual needs. Illustratively, the swing arm 34 includes a primary swing arm 341, a secondary swing arm 342, and a synchronization swing arm 343. The first door panel 32 and the second door panel 33 can rotate around the shaft body 31 by the combined action of the main swing arm 341 and the sub swing arm 342. Under the action of the synchronous swing arm 343, the rotation angles of the first door panel 32 and the second door panel 33 relative to the shaft body 31 are kept synchronous and consistent. The swing arm 34 is provided with a swing arm support 340 facing a side of the flexible display panel. The mobile phone further comprises a flexible screen supporting structure 35, wherein the flexible screen supporting structure 35 is arranged between the swing arm supporting part 340 and the flexible display panel. Fig. 12 is a flattened cross-sectional view of a rotating shaft at a main swing arm according to an embodiment of the present application, and fig. 13 is a superimposed cross-sectional view of a rotating shaft at a main swing arm according to an embodiment of the present application, see fig. 12 and fig. 13. Illustratively, a side of the main swing arm 341 facing the flexible display panel is provided with a main swing arm support 3401. One surface of the main swing arm supporting part 3401 facing the flexible display panel is in a cambered surface shape, and the cambered surface protrudes towards one side close to the flexible display panel. When the first door plate 32 and the second door plate 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 is located are unfolded to be a plane, the cambered surface of the main swing arm supporting portion 3401 is in line contact with the flexible screen supporting structure 35, the main swing arm supporting portion 3401 can support the flexible screen supporting structure 35, and the flexible screen supporting structure 35 is prevented from sinking. When the first door plate 32 and the second door plate 33 of the rotating shaft 3 are in the overlapped 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 supporting part 3401 is attached to the flexible screen supporting structure 35 and used for supporting the flexible screen supporting structure 35 to provide enough support for the flexible display panel. Fig. 14 is a flattened cross-sectional view of a shaft at a secondary swing arm according to an embodiment of the present application, see fig. 14. The side of the sub-swing arm 342 facing the flexible display panel is provided with a sub-swing arm supporting part 3402. The shape of the side of the sub swing arm supporting part 3402 facing the flexible display panel may be determined according to actual needs. For example, the shape of the side of the sub swing arm supporting part 3402 facing the flexible display panel may be a plane. When the first door panel 32 and the second door panel 33 of the rotating shaft 3 are in the flattened state, the flexible display panel and the flexible screen supporting structure 35 opposite to the area where the rotating shaft 3 is located are unfolded to be a plane, the plane of the auxiliary swing arm supporting portion 3402 is in surface contact with the flexible screen supporting structure 35, and the auxiliary swing arm supporting portion 3402 supports the flexible screen supporting structure 35 to prevent the flexible screen supporting structure 35 from sinking. In the process of converting the first door panel 32 and the second door panel 33 of the rotation shaft 3 from the flattened state to the folded state, the sub-swing arm 342 is partially retracted 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 sub-swing arm support 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 overlapped state, only the main swing arm supporting portion 3401 supports the flexible screen supporting structure 35 with the curved region being arc-shaped, and the auxiliary swing arm supporting portion 3402 does not support the portion of the flexible screen supporting structure 35 with the curved region being arc-shaped. Fig. 15 is a flattened cross-sectional view of a rotating shaft at a synchronous swing arm according to an embodiment of the present application, see fig. 15. The side of the synchronization swing arm 343 facing the flexible display panel is provided with a synchronization swing arm support 3403. The shape of the side of the synchronization swing arm support portion 3403 facing the flexible display panel may be determined according to actual needs. For example, a shape of a side of the synchronization swing arm support 3403 facing the flexible display panel may be a plane. When the first door plate 32 and the second door plate 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 is located are unfolded to be a plane, the plane of the synchronous swing arm supporting part 3403 is in surface contact with the flexible screen supporting structure 35, and the synchronous swing arm supporting part 3403 supports the flexible screen supporting structure 35 to prevent the flexible screen supporting structure 35 from sinking. In the process of converting the first door panel 32 and the second door panel 33 of the rotation shaft 3 from the flattened state to the folded state, the synchronization swing arm is partially retracted 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 synchronization swing arm support 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 supporting portion 3401 supports the flexible screen supporting structure 35 with the curved region being arc-shaped, and the synchronous swing arm supporting portion 3403 does not support the portion of the flexible screen supporting structure 35 with the curved region being arc-shaped. Of course, the above-described embodiments are merely examples, and in actual implementation, the shapes of the main swing arm support portion 3401, the sub swing arm support portion 3402, and the side of the synchronization swing arm support portion 3403 facing the flexible display panel may also be set according to actual needs. For example, both the side of the sub swing arm support portion 3402 and the side of the synchronization swing arm support portion 3403 facing the flexible display panel may be provided as arc surfaces.
With continued reference to fig. 5, 6, 9, and 11, the flexible screen support structure 35 may include a flexible screen support body 351 including opposing first and second faces, the first face divided into a first region proximate the first door panel 32 and a second region proximate the second door panel 33, the first face being oriented toward the flexible display panel. The flexible screen support structure 35 may also include a first rigid reinforcing sheet 352 and a first flexible reinforcing sheet 353 attached to the first region and a second rigid reinforcing sheet 354 and a second flexible reinforcing sheet 355 attached to the second region. The first stiffening sheet 352 is located on the side of the first stiffening sheet 353 remote from the second region and the second stiffening sheet 354 is located on the side of the second stiffening sheet 355 remote from the first region. Between the first 353 and second 355 flexible reinforcing sheets, there is also provided a recessed region 356 spanning the first and second regions, the recessed region 356 being free of such reinforcing sheets. Because the flexible screen supporting structure 35 of the groove region 356 is not attached with the reinforcing sheet, the flexible screen supporting structure is soft and easy to bend, and is beneficial to changing the flexible screen supporting structure 35 between the flattened state and the folded state. The first flexible reinforcing sheet 353 and the second flexible reinforcing sheet 355 serve as flexible reinforcing sheets of the flexible screen support body 351, and the deformation resistance is enhanced on the basis of the flexible screen support body 351, so that the supporting force provided by the main swing arm supporting portion 3401, the auxiliary swing arm supporting portion 3402 and the synchronous swing arm supporting portion 3403 to the flexible screen support body 351 can be uniformly dispersed to each region of the flexible screen support body 351, and the situation that the main swing arm supporting portion 3401, the auxiliary swing arm supporting portion 3402 and the corresponding flexible screen support body 351 of the synchronous swing arm supporting portion 3403 are too soft due to the fact that the flexible screen support body 351 is too soft is avoided. The projection of the first stiffening tab 352 falls on the first door panel 32 in a projection direction perpendicular to the plane of extension of the first stiffening tab 352. The projection of the second stiffening sheet 354 falls on the second door panel 33 in a projection direction perpendicular to the plane of extension of the second stiffening sheet 354. The first rigid reinforcing sheet 352 and the second rigid reinforcing sheet 354 are both rigid members, and therefore, the flexible screen support body 351 attached thereto cannot be deformed. The design mode realizes that the flexible screen support body 351 is provided with the rigid part and the flexible part at the same time, and the rigid part and the flexible part can be naturally combined.
Fig. 16 is a schematic structural view of a flexible supporting screen structure according to an embodiment of the present application, see fig. 16. The flexible screen support structure 35 further includes an elastic sliding component for movably connecting the edge of the flexible screen support structure 35 with the first door panel 32 or the second door panel 33. The present application is not limited to the specific constitution of the elastic sliding member. Illustratively, the resilient slide assembly includes a slider 357 and a spring 358, each provided at an edge of the first region remote from the second region, and at an edge of the second region remote from the first region. The slider 357 is connected to the first stiffening plate 352 and the second stiffening plate 354 through the fenestration of the flexible screen support body 351. The slider 357 includes a slider body 3571, a first sub-slider 3572, a second sub-slider 3573 located at both sides of the slider body 3571, and a slider spring coupling post 3574 coupled to the slider body 3571. The extending direction of the slider spring connecting post 3574 is parallel to the width direction of the mobile phone, and the extending direction is a direction approaching the shaft body 31. Fig. 17 is a schematic structural view of a notch according to an embodiment of the present application, see fig. 17. A notch 359 is provided at the edge of the first door panel 32 and the second door panel 33 away from the shaft body 31, and the notch 359 includes a first side wall 3591, a second side wall 3592 and a bottom wall 3593. first chute 35911 is formed on first sidewall 3591, first chute 35911 may be formed perpendicular to first sidewall 3591, and first chute 35911 extends from opening of notch 359 to bottom wall 3593. The second side wall 3592 is provided with a second sliding groove 35921, the second sliding groove 35921 may be perpendicular to the second side wall 3592, and the second sliding groove 35921 extends from the opening of the notch 359 to the bottom wall 3593. Near the bottom wall 3593, a door leaf spring attachment post 3594 is provided that corresponds in position to the slider spring attachment post 3574. The slider body 3571 can be inserted into the notch 359 from the opening of the notch 359, and at the same time, the first sub-slider 3572 is inserted into the first chute 35911, the second sub-slider 3573 is inserted into the second chute 35921, and two ends of the spring 358 are respectively sleeved on the slider spring connecting post 3574 and the door plate spring connecting post 3594. Because the mobile phone with the foldable and bendable screen is required 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 is kept unchanged. Therefore, in the process of converting the folded state into the flattened state, the first door panel 32 and the second door panel 33 stretch the flexible screen supporting structure 35 to two sides respectively. When the flexible stay structure 35 is stretched, the springs 358 are compressed, and at this time, the partial areas of the first door panel 32 and the second door panel 33 covered by the flexible stay structure 35 are exposed, thereby solving the problem of insufficient length of the flexible stay structure 35. In the process of converting the flattened state into the folded state, the force of stretching the flexible screen supporting structure 35 to the two sides by the first door plate 32 and the second door plate 33 is reduced, and the springs 358 in the compressed state are gradually released. the flexible stay structure 35 covers more of the first door panel 32 and the second door panel 33. Wherein the flexible screen support body 351, the first flexible reinforcing sheet 353 and the second flexible reinforcing sheet 355 may be soft rubber sheets, and the first rigid reinforcing sheet 352 and the second rigid reinforcing sheet 354 may be steel sheets. The flexible screen support body 351 and the first flexible reinforcing sheet 353, the second flexible reinforcing sheet 355, the first rigid reinforcing sheet 352 and the second rigid reinforcing sheet 354 may be connected by means of adhesive. The slider 357 may be made of metal, and the connection between the slider 357 and the first stiffening plate 352 and the connection between the slider 357 and the second stiffening plate 354 may be made by welding.
Of course, the above embodiments are merely exemplary of the composition and arrangement of the flexible screen structures. In fact, any flexible supporting structure may be used without departing from the spirit of the present application, and the embodiments of the present application are not limited to the composition and arrangement of the flexible supporting structure. For example, the slider 357 and the springs 358 may also be omitted, and the notches 359 are not provided at the edges of the first door panel 32 and the second door panel 33. The first rigid reinforcing sheet 352 is directly and fixedly connected to the first door panel 32, the second rigid reinforcing sheet 354 is directly and fixedly connected to the second door panel 33, and the flexible screen support body 351 is an elastic member. The flexible stay body 351 is stretched and released when the first door panel 32 and the second door panel 33 are changed between the flattened state and the folded state. On this basis, a first rigid reinforcing sheet 352 and a second rigid reinforcing sheet 354 may be provided, the first rigid reinforcing sheet 352 being fixedly connected to the first door panel 32, the second rigid reinforcing sheet 354 being fixedly connected to the second door panel 33. The flexible stay body 351 may be directly connected between the first door panel 32 and the second door panel 33 without providing the first and second rigid reinforcing sheets 352 and 354. In other embodiments, the first and second flexible reinforcement sheets 353, 355 may also be omitted. In other embodiments, the first flexible reinforcing sheet 353 and the second flexible reinforcing sheet 355 may not be provided, the flexible screen support body 351 may be designed to have a structure with different thicknesses according to different positions, and the positions where the first flexible reinforcing sheet 353 and the second flexible reinforcing sheet 355 are provided are thickened.
