[0002] At present, with the development of electronic technology, foldable electronic devices are gradually popularized, such as foldable screen mobile phones, foldable notebooks, foldable tablets, etc. Generally, the screens of these electronic devices are made of flexible materials. When the user needs to carry the electronic device conveniently, the screen can be folded up. When the user needs a larger screen for visual experience, the screen can be unfolded for use.

[0003] However, in the related art, in the process of folding, the folding radius of the inner layer of the screen is small, and the folding radius of the outer layer of the screen is large, so that the layers of the screen slide relative to each other.

[0023] like Figure 1 As shown, the electronic device according to some embodiments of the present application includes: a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are rotatably connected, and the first shell 1 and the second shell 2 can switch between an unfolded state and a folded state; a flexible screen assembly 3, the flexible screen assembly 3 is arranged on the first shell 1 and the second shell 2; a thrust mechanism 4, the thrust mechanism 4 is connected to the flexible screen assembly 3, at least in the folded state, the unfolded state and in the process of switching from the unfolded state to the folded state, the thrust mechanism 4 can push and pull the flexible screen assembly 3 in the direction away from the rotation axis C of the first shell 1.

[0024] In an embodiment of the present application, the electronic device includes a first shell 1, a second shell 2, a flexible screen assembly 3 and a thrust mechanism 4. The first shell 1 and the second shell 2 are rotatably connected, so that the first shell 1 and the second shell 2 can switch between an unfolded state and a folded state. The thrust mechanism 4 can push and pull the flexible screen assembly 3 in a direction away from the rotation axis C, so that the various layers of the flexible screen assembly 3 will also be subjected to outward pulling force, thereby reducing the relative slippage between the various layers of the flexible screen assembly 3 and improving the creases generated during the folding process of the flexible screen assembly 3.

[0025] It can be understood that the various laminated layers of the flexible screen assembly 3 are connected by adhesive bonding, and during the multiple unfolding and folding processes of the first shell 1 and the second shell 2, slippage is likely to occur between the various laminated layers of the flexible screen assembly 3, thereby causing the portion of the flexible screen assembly 3 corresponding to the rotation axis C (such as Figure 1 By stretching the flexible screen assembly 3 away from the rotation axis C through the thrust mechanism 4, the slippage between the layers of the flexible screen assembly 3 can be reduced, thereby improving the crease of the flexible screen assembly 3 corresponding to the rotation axis C.

[0026] Specifically, in the unfolded state, the first shell 1 and the second shell 2 are arranged side by side, and the flexible screen assembly 3 is flattened on the first shell 1 and the second shell 2; in the folded state, the first shell 1 and the second shell 2 are stacked, and the part of the flexible screen assembly 3 located on the first shell 1 is arranged opposite to or back to back with the part located on the second shell 2.

[0030] In this embodiment, the thrust mechanism 4 includes a first magnetic part 40 and a second magnetic part 41. The first magnetic part 40 is arranged on the side of the flexible screen assembly 3 away from the rotation axis C, and the second magnetic part 41 is arranged corresponding to the first magnetic part 40. In this way, under the adsorption action of the first magnetic part 40 and the second magnetic part 41, the flexible screen assembly 3 can be stretched in the direction away from the rotation axis C, thereby improving the crease problem.

[0031] In a specific application, the first magnetic member 40 and the second magnetic member 41 include at least one of a permanent magnet and an electromagnet.

[0032] It can be understood that, in the case that the thrust mechanism 4 is arranged at the first shell 1, the second magnetic member 41 is arranged at the end of the first shell 1 away from the second shell 2, and in the case that the thrust mechanism 4 is arranged at the second shell 2, the second magnetic member 41 is arranged at the end of the second shell 2 away from the first shell 1. Correspondingly, in the case that the thrust mechanism 4 is arranged at both the first shell 1 and the second shell 2, the second magnetic member 41 arranged at the first shell 1 is arranged at the end of the first shell 1 away from the second shell 2, and the second magnetic member 41 arranged at the second shell 2 is arranged at the end of the second shell 2 away from the first shell 1.

Figure 3 In this embodiment, the second magnetic member 41 comprises the transition plate 410 and the excitation assembly 411, the transition plate 410 is connected with the first shell 1 or the second shell 2, the first conductive part 4102 is arranged on the transition plate 410, the second conductive part 4152 is arranged on the excitation assembly 411, the first conductive part 4102 and the second conductive part 4152 are in conduction, so that the excitation assembly 411 generates a magnetic field after being powered, and then the first magnetic member 40 is adsorbed.

[0034] In specific applications, the first magnetic member 40 is a magnetic material (which can be neodymium iron boron, ferrite, aluminum-nickel-cobalt, etc.). The excitation assembly 411 forms a coil after being powered, and then generates a magnetic field, which magnetizes the first magnetic member 40, and then adsorbs the first magnetic member 40.

[0035] Further, the transition plate 410 is connected with the battery of the electronic device, and the excitation assembly 411 is powered by the battery, thereby saving the space occupied by the power supply device of the excitation assembly 411.

[0036] In a possible design, in the case that the first shell 1 and the second shell 2 are in the unfolded state, the excitation assembly 411 is in conduction with the transition plate 410, so that the excitation assembly 411 generates a magnetic field, and then the flexible screen assembly 3 is pushed and pulled away from the rotation axis C under the adsorption of the first magnetic member 40 and the excitation assembly 411, thereby improving the crease.

[0037] Further, in the case that the first shell 1 and the second shell 2 are in the folded state, the excitation assembly 411 is powered off.

[0038] Further, in the case that the first shell 1 and the second shell 2 are in the folded state, the excitation assembly 411 is powered off.

[0039] As Figure 3 and Figure 4 shown, according to some embodiments of the application, the excitation assembly 411 comprises a bracket 412, the bracket 412 comprises a first bracket 413 and a second bracket 414, the second bracket 414 is arranged in a spiral on the first bracket 413; an excitation piece 415, the excitation piece 415 is arranged in a spiral on the first bracket 413, and the second bracket 414 is arranged staggered with the excitation piece 415.

The excitation piece 415 is arranged in a spiral on the first bracket 413 and arranged staggered with the second bracket 414, so that the excitation piece 415 forms a coil after being electrified, thereby generating a magnetic field, at the same time, the second bracket 414 can also enhance the magnetic field intensity of the excitation piece 415, thereby improving the adsorption effect on the first magnetic piece 40.

[0041] In specific applications, the first bracket 413 and the second bracket 414 are of an integrated structure.

[0042] Further, the bracket 412 is a silicon steel sheet. The excitation piece 415 comprises a copper sheet.

[0043] Further, the second conductive part 4152 is arranged on the first bracket 413 between two adjacent second brackets 414. Specifically, the number of the second conductive part 4152 is two, and the two second conductive parts 4152 are arranged at the innermost side and the outermost side of the second bracket 414 respectively.

[0044] As Figure 5 shown, according to some embodiments of the application, the excitation assembly 411 further comprises an insulating layer 416 arranged between the excitation piece 415 and the first bracket 413; a first reinforcing sheet 417 arranged between the adapter plate 410 and the bracket 412, the first reinforcing sheet 417 is provided with a via hole, and the first conductive part 4102 and the second conductive part 4152 extend into the via hole.

[0045] In this embodiment, the excitation assembly 411 further comprises an insulating layer 416 and a first reinforcing sheet 417, the insulating layer 416 is arranged between the excitation piece 415 and the first bracket 413 to avoid the excitation piece 415 from being in conduction with external metal. The first reinforcing sheet 417 is arranged between the adapter plate 410 and the bracket 412 to reliably connect the adapter plate 410 and the bracket 412. The first reinforcing sheet is provided with a via hole, and the first conductive part 4102 and the second conductive part 4152 extend into the via hole from the opposite sides of the via hole and are connected. On the basis of ensuring the conduction of the adapter plate 410 and the first bracket 413, the space occupied by the first conductive part 4102 and the second conductive part 4152 can be reduced.

[0046] Specifically, the number of the via holes is set according to actual conditions, and further, the number of the via holes is the same as the number of the first conductive parts 4102 and is set in one-to-one correspondence with the first conductive parts 4102.

[0048] In this embodiment, the electronic device further comprises a second reinforcing sheet 32 arranged at the bottom of the flexible screen 30, the second reinforcing sheet 32 can support the flexible screen 30 and strengthen the strength of the flexible screen 30. One side of the second reinforcing sheet 32 is flexibly connected with the flexible screen 30 through the flexible glue, the other side of the second reinforcing sheet 32 is flexibly connected with the first shell 1 and the second shell 2 through the flexible piece, the pushing force mechanism 4 is connected with the second reinforcing sheet 32, and then the second reinforcing sheet 32 is pushed and pulled to drive the flexible screen 30 to move, so that the creases on the flexible screen 30 are flattened.

[0049] It can be understood that the pushing force mechanism 4 exerts a force on the second reinforcing sheet 32 at the bottom of the flexible screen 30 to achieve the effect of reducing the creases. Since the flexible screen 30 and the second reinforcing sheet 32 are connected through the flexible glue, and the layers of the flexible screen 30 are also connected through the glue, when the second reinforcing sheet 32 at the bottom of the flexible screen 30 is subjected to a lateral pulling stress, the layers of the flexible screen 30 will also be subjected to a partial outward pulling effect, thereby reducing the relative sliding between the layers and reducing the depth of the concave.

[0050] As shown in Figure 2 According to some embodiments of the present application, at least one of the first shell 1 and the second shell 2 is provided with a receiving portion 10, a part of the second reinforcing sheet 32 is arranged to be bent into the receiving portion 10, the first magnetic piece 40 is arranged on the part of the second reinforcing sheet 32 located in the receiving portion 10, and the second magnetic piece 41 is arranged in the receiving portion 10.

[0051] In this embodiment, at least one of the first shell 1 and the second shell 2 is provided with a receiving portion 10, the second reinforcing sheet 32 is arranged to be bent into the receiving portion 10, the first magnetic piece 40 is arranged on the part of the second reinforcing sheet 32 located in the receiving portion 10, and the distance between the first magnetic piece 40 and the second magnetic piece 41 is shortened, thereby improving the adsorption force. Further, the second magnetic piece 41 arranged in the receiving portion 10 and the first magnetic piece 40 can be adsorbed to each other, thereby realizing the stretching of the flexible screen 30.

[0052] According to some embodiments of the present application, the first magnetic member 40 and the second reinforcing sheet 32 ​​are an integrated structure.

[0053] In this embodiment, the first magnetic member 40 and the second reinforcing sheet 32 ​​are an integrated structure, which improves the connection strength between the first magnetic member 40 and the second reinforcing sheet 32, thereby ensuring the reliability of the interaction between the first magnetic member 40 and the second magnetic member 41.

[0054] like Figure 3 As shown, according to some embodiments of the present application, one of the first magnetic member 40 and the second reinforcing sheet 32 ​​has a plurality of protrusions 402 , and the other has a plurality of recesses 320 , and the protrusions 402 are disposed in the recesses 320 .

[0055] In this embodiment, a plurality of protrusions 402 are provided on one of the first magnetic member 40 and the second reinforcement sheet 32, and a plurality of recesses 320 are provided on the other of the first magnetic member 40 and the second reinforcement sheet 32. The protrusions 402 are provided in the recesses 320, so that the first magnetic member 40 is embedded in the second reinforcement sheet 32, thereby improving the connection reliability between the two.

[0056] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, a plurality of through holes 322 are provided on the second reinforcing plate 32 , and the plurality of through holes 322 are located at the rotation axis C.

[0057] In this embodiment, a plurality of through holes 322 are provided on the second reinforcing sheet 32, and the plurality of through holes 322 are located at the rotation axis C. After the plurality of through holes 322 are provided, the second reinforcing sheet 32 ​​has a certain flexibility, and thus when the first shell 1 and the second shell 2 rotate relative to each other, the area of ​​the second reinforcing sheet 32 ​​where the through holes 322 are provided can bend accordingly.

[0058] According to some embodiments of the present application, the flexible member includes flexible glue.

[0059] In this embodiment, flexible glue is provided on the side of the second reinforcing sheet 32 ​​facing the first shell 1 and the second shell 2, so that the second reinforcing sheet 32 ​​is connected to the first shell 1 and the second shell 2 through the flexible glue, thereby enabling the second reinforcing sheet 32 ​​to have a certain displacement relative to the first shell 1 and the second shell 2.

[0060] In a specific application, the middle position of the second reinforcing sheet 32 is a through hole 322, allowing a certain degree of displacement deformation; the bending position on the left side of the second reinforcing sheet 32 is integrally embedded with a magnetic material (which can be: neodymium iron boron, ferrite, aluminum-nickel-cobalt, etc.), which is easy to magnetize when approaching the magnetic field area, and is attracted after obtaining magnetism. The second reinforcing sheet 32 is bonded between the first shell 1 and the second shell 2 through the foam glue 34 (a flexible glue), allowing the second reinforcing sheet 32 to be dislocated relative to the first shell 1 or the second shell 2 by a certain displacement.

[0061] Specifically, the power supply supplies power to the adapter board 410 (which can be a flexible circuit board), which is integrally bonded with the first reinforcing plate and is fixed on the first shell 1 or the second shell 2 through the back adhesive 418. The adapter board 410 has a first conductive part 4102, which includes a positive and negative interface and is connected with a second conductive part 4152 of the excitation assembly 411 to provide a constant magnetic field.

[0062] Specifically, as shown in Figure 4 the excitation assembly 411 includes a bracket 412 and an excitation piece 415, which is similar to a "Hanzi" shaped winding structure. When the first conductive part 4102 and the second conductive part 4152 are connected, a constant magnetic field is generated in the axial direction perpendicular to the plane of the excitation piece 415. An insulating layer 416 is attached between the excitation piece 415 (copper sheet) and the bracket 412 to prevent the excitation piece 415 from being conductive with external metal, and is bonded to the upper surface of the insulating layer 416. There is a second bracket 414 made of silicon steel sheet between the gaps of each coil of the excitation piece 415, which has good magnetic conductivity and can increase the magnetic field.

[0063] Therefore, the excitation assembly 411 generates a stable magnetic field each time it is powered on, magnetizes the magnetic material on the second reinforcing sheet 32, and thereby attracts the second reinforcing sheet 32 to move outward. The excitation piece 415 includes a copper sheet.

[0064] As shown in Figure 6 According to some embodiments of the present application, the thrust mechanism 4 includes a guide shaft 42 connected to the first shell 1 or the second shell 2 and located below the flexible screen assembly 3, the guide shaft 42 extending away from the rotation axis C; a connecting part 43 provided on the guide shaft 42, the connecting part 43 being connected with the bottom of the flexible screen assembly 3 and being capable of moving relative to the axis of the guide shaft 42; and an elastic member 44 provided on the guide shaft 42, one end of the elastic member 44 being connected with the guide shaft 42 and the other end being connected with the connecting part 43, the elastic member 44 being in a deformed state to push the connecting part 43 away from the rotation axis C of the first shell 1 or the second shell 2 at least in the folded state, the unfolded state, and the process of switching from the unfolded state to the folded state.

[0065] In this embodiment, the thrust mechanism 4 includes a guide shaft 42, a connecting portion 43 and an elastic member 44. The guide shaft 42 is provided on the first shell 1 or the second shell 2, and extends in a direction away from the rotation axis C. The connecting portion 43 is movably connected to the guide shaft 42. One end of the elastic member 44 is connected to the guide shaft 42, and the other end is connected to the connecting portion 43. At least in the folded state, the unfolded state, and the process of switching from the unfolded state to the folded state, the elastic member 44 is in a deformed state. In this way, under the drive of the elastic member 44, the connecting portion 43 applies a force to the flexible screen assembly 3 in a direction away from the rotation axis C, thereby improving the crease problem on the flexible screen assembly 3.

[0066] Furthermore, the extending direction of the guide shaft 42 is perpendicular to the rotation axis C.

[0067] Furthermore, the connecting portion 43 is connected to the second reinforcing piece 32 of the flexible screen assembly 3 , and the flexible screen 30 is pushed to move by pushing the second reinforcing piece 32 .

[0068] Furthermore, the connection portion 43 is fixedly connected to the second reinforcing sheet 32. Specifically, the connection portion 43 is connected to the second reinforcing sheet 32 ​​by welding.

[0069] like Figure 6 As shown, according to some embodiments of the present application, a mounting hole 12 is provided on the first shell 1 or the second shell 2, the guide shaft 42 is provided on the side of the first shell 1 or the second shell 2 away from the flexible screen assembly 3, and the connecting part 43 is passed through the mounting hole 12.

[0070] In this embodiment, a mounting hole 12 is provided on the first shell 1 or the second shell 2, the connecting portion 43 is passed through the mounting hole 12, and the guide shaft 42 is located on the side of the first shell 1 or the second shell 2 away from the flexible screen assembly 3, thereby avoiding occupying the space below the flexible screen assembly 3, thereby reducing costs and making the electronic device compact.

[0071] Furthermore, an axial hole is provided on the connecting portion 43, and the guide shaft 42 is passed through the axial hole, wherein the minimum value of the gap between the inner wall surface of the axial hole of the connecting portion 43 and the guide shaft 42 is greater than the deformation amount of the flexible glue under the second reinforcement sheet 32, so as to avoid interference between the connecting portion 43 and the guide shaft 42 when pressing the flexible screen 30.

[0072] like Figure 6 As shown, according to some embodiments of the present application, the elastic member 44 is located on a side of the connecting portion 43 close to the rotation axis C, and the elastic member 44 is in a compressed state.

[0073] In this embodiment, the elastic member 44 is arranged on the side of the connecting portion 43 close to the rotation axis C, and the elastic member 44 is in a compressed state, so that the elastic member 44 can push the connecting portion 43 away from the rotation axis C, and further push the flexible screen assembly 3 away from the rotation axis C through the connecting portion 43.

[0074] Of course, the elastic member 44 can also be arranged on the side of the connecting portion 43 away from the rotation axis C, and the elastic member 44 is in a stretched state, so as to pull the flexible screen assembly 3 away from the rotation axis C.

[0075] In a specific application, the connecting portion 43 is fixedly connected below the second reinforcing sheet 32 (which can be connected by laser welding), the flexible screen assembly 3 is first attached to the first shell 1 or the second shell 2 through the foam adhesive 34, then the guide shaft 42, the stop ring 45 and the elastic member 44 are inserted from one side through the through hole 322 of the connecting portion 43 (the aperture and the gap of the guide shaft 42 need to be larger than the deformation amount of the foam adhesive 34), and finally the screws at both ends of the guide shaft 42 are fixed. In this way, under the action of the elasticity of the elastic member 44, the second reinforcing sheet 32 is always subjected to an outward force. The elastic member 44 includes a compression spring.

[0076] According to some embodiments of the present application, the number of the thrust mechanisms 4 is multiple, and the multiple thrust mechanisms 4 are symmetrically arranged along the rotation axis C, wherein along the rotation axis C, the two ends of the multiple thrust mechanisms 4 are arranged close to the first shell 1 or the second shell 2.

[0077] In this embodiment, the number of the thrust mechanisms 4 is multiple, and the multiple thrust mechanisms 4 are symmetrically arranged along the rotation axis C, that is, the thrust mechanisms 4 are arranged on the first shell 1 and the second shell 2, so that under the action of the thrust mechanisms 4, the flexible screen assembly 3 can be pushed and pulled away from the two sides of the rotation axis C, thereby improving the optimization effect of the fold mark.
