Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments.

[0044] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the electronic device provided by the embodiment of the present disclosure includes a first body 1 and a second body 2, and the first body 1 and the second body 2 are connected by a hinge mechanism 3 so that the first body 1 and the second body 2 can be folded or unfolded relative to each other. The first body 1 and the second body 2 can be components connected to the hinge mechanism 3 respectively, and the hinge mechanism 3 can drive the first body 1 to rotate in a direction close to or away from the second body 2 to realize the opening and closing of the electronic device. When the electronic device is a laptop computer, the first body 1 can be a flexible screen 4 component, and the second body 2 can be a host component.

[0045] The tensioning mechanism is arranged on the second body 2; the flexible screen 4 has a first edge and a second edge 42 arranged opposite to each other, the first edge is arranged on the first body 1, and the second edge 42 is connected to the tensioning mechanism; optionally, the flexible screen 4 may include a first part and a second part, the first part is connected to the first body 1, and the second part is arranged on the second body 2, the first part and the second part may be an integral structure, the first part may be a part of the flexible screen 4 covering the first surface of the first body 1 in a folded state, and the second part may be a part of the flexible screen 4 other than the first part, specifically, the second part may be located in the second body 2. The second part may be slidably connected to the second body 2 so as to slide relative to the second body 2. When part or all of the second part moves to cover the first surface, part or all of the second part originally covering the first surface is transformed into the first part. The first edge is located at the edge of the first part away from the second part, and the second edge 42 is located at the edge of the second part away from the first part.

[0046] Optionally, the first body 1 may include a first shell, the first shell forms a first accommodating space, the first electronic component is arranged in the first accommodating space, the first electronic component may be the first part of the flexible screen 4, or may be a transfer board of the first part of the flexible screen 4. The second body 2 may include a second shell, the second shell forms a second accommodating space, the second electronic component is arranged in the second accommodating space, and the second electronic component is any one of the components electrically connected to the first electronic component. Optionally, the second electronic component may be a display driver board.

[0047] The rotating shaft mechanism 3 is a mechanical device used to connect the first body 1 and the second body 2 and realize the relative rotation of the first body 1 and the second body 2. Optionally, the rotating shaft mechanism 3 can be a hinge.

[0048] The tensioning mechanism is disposed on the second body 2, and the second edge 42 of the flexible screen 4 is connected to the tensioning mechanism. When the first body 1 rotates relative to the second body 2, the tensioning mechanism can tension the flexible screen 4, and the length change of the flexible screen 4 inside the system is compensated by the tensioning mechanism, so that the flexible screen 4 is kept slightly taut to keep it flat, reducing the possibility of folding the flexible screen 4. Optionally, when the first body 1 rotates relative to the second body 2, the tensioning mechanism can apply a pulling force to the flexible screen 4, and the direction of the pulling force is opposite to the movement direction of the flexible screen 4 when the first body 1 is opened relative to the second body 2, thereby achieving the guiding and tensioning effect on the flexible screen 4.

[0049] Optionally, the first edge of the flexible screen 4 can be connected to the first electronic component on the first body 1, and the first edge is subjected to the force of the first body 1. The second edge 42 of the flexible screen 4 is connected to the second electronic component on the second body 2 through a tensioning mechanism, and the second edge 42 is subjected to the force of the second body 2. The second edge 42 of the flexible screen 4 is pulled by the tensioning mechanism, and the flexible screen 4 is subjected to the pulling force of the tensioning mechanism, so that the flexible screen 4 can maintain balance under the combined action of the above forces, so that the flexible screen 4 remains slightly taut to keep it flat, reducing the possibility of the flexible screen 4 folding.

[0050] In some specific embodiments, the tensioning mechanism includes a sliding member 51, a tension rope 52, and an elastic member 53. The sliding member 51 is slidably disposed on the second body 2. The first end 521 of the tension rope 52 is connected to the first body 1. After the tension rope 52 bypasses the sliding member 51, the second end 522 of the tension rope 52 is connected to the second edge 42 of the flexible screen 4. The elastic member 53 is disposed between the sliding member 51 and the second body 2, so that when the first body 1 rotates relative to the second body 2, the elastic force of the elastic member 53 enables the tension rope 52 to provide a tension force for the flexible screen 4. The first edge is subjected to the acting force of the first body 1, and the second edge 42 is subjected to the acting force of the tension rope 52. The second edge 42 of the flexible screen 4 is pulled by the tension rope 52 and the elastic member 53. The flexible screen 4 is subjected to the pulling force of the tension rope 52 and the elastic member 53. Since the elastic member 53 has elasticity and can undergo elastic deformation, the flexible screen 4 can be kept slightly taut to maintain flatness, reducing the possibility of the flexible screen 4 being folded. The two ends of the elastic member 53 can be respectively connected to the sliding member 51 and the second body 2. By defining the deformation direction of the elastic element, the movement direction of the sliding member 51 can be defined, so as to constrain the movement form of the flexible screen 4, so that the flexible screen 4 can maintain balance under the combined action of the above acting forces, so that the flexible screen 4 is kept slightly taut to maintain flatness, reducing the possibility of the flexible screen 4 being folded.

[0051] In some specific embodiments, the sliding member 51 includes a slider and a first pulley 511 disposed on the slider. The tension rope 52 is wound around the first pulley 511, and the elastic member 53 is disposed between the slider and the second body 2. In this embodiment, the pulling force of the elastic member 53 acts on the slider, and thus can act on the first pulley 511. Through the first pulley 511, the pulling force acts on the tension rope 52. Through the tension rope 52, the pulling force can act on the second edge 42 of the flexible screen 4, so that the flexible screen 4 is kept slightly taut to maintain flatness, reducing the possibility of the flexible screen 4 being folded.

[0052] Optionally, the tension rope 52 can have elasticity and can undergo elastic deformation, so that the flexible screen 4 is kept slightly taut to maintain flatness, reducing the possibility of the flexible screen 4 being folded.

[0053] In some specific embodiments, the sliding member 51 is a movable pulley. In this embodiment, the pulling force of the elastic member 53 acts on the movable pulley, and through the movable pulley, the pulling force acts on the tension rope 52. Through the tension rope 52, the pulling force can act on the second edge 42 of the flexible screen 4, so that the flexible screen 4 is kept slightly taut to maintain flatness, reducing the possibility of the flexible screen 4 being folded.

[0054] In some specific embodiments, the tensioning mechanism includes a base 54 and a guide member 55; the base 54 is connected to the second body 2. Optionally, the base 54 and the second body 2 can be connected by fasteners. The guide member 55 is disposed on the base 54. Optionally, the guide member 55 is fixed to the base 54. Optionally, the base 54 is formed with a mounting groove, and the guide member 55 is disposed in the mounting groove. The sliding member 51 is slidably engaged with the guide member 55. Optionally, the guide member 55 can be columnar, and the sliding member 51 is provided with a guide hole, and the guide member 55 passes through the guide hole. The elastic member 53 is sleeved on the guide member 55, and the elastic member 53 is located between the sliding member 51 and the base 54. Optionally, the two ends of the elastic member 53 are respectively abutted against the side wall of the base 54 and the sliding member 51, and the pulling force of the elastic member 53 acts on the sliding member 51, so that it can act on the tension rope 52. Through the tension rope 52, the pulling force can act on the second edge 42 of the flexible screen 4, so that the flexible screen 4 is kept slightly taut to keep flat, reducing the possibility of the flexible screen 4 folding.

[0055] In some specific embodiments, the first body 1 includes a fixed bracket 11, a movable bracket 12 and a driving member; the fixed bracket 11 is provided with a second pulley 111; the movable bracket 12 is movably connected to the fixed bracket 11, and the flexible screen 4 is disposed on the side of the movable bracket 12 facing away from the fixed bracket 11; the driving member is disposed on the fixed bracket 11 and is used to drive the movable bracket 12 to slide relative to the fixed bracket 11; wherein, the first end 521 of the tension rope 52 bypasses the second pulley 111 and is connected to the movable bracket 12.

[0056] Optionally, the driving member can include a driving motor and a transmission mechanism connected to the driving motor. The transmission mechanism is respectively connected to the output end of the driving structure and the movable bracket 12. By driving the transmission mechanism with the driving motor, the movable bracket 12 can be moved relative to the fixed bracket 11.

[0057] In this embodiment, the driving member drives the moving bracket 12, enabling the moving bracket 12 to move relative to the fixed bracket 11, so that the first body 1 can have a switchable first display state and a second display state. When the moving bracket 12 moves relative to the fixed bracket 11, the overall size of the first body 1 formed by the fixed bracket 11 and the moving bracket 12 can change. The flexible screen 4 can adapt to the overall size formed by the fixed bracket 11 and the moving bracket 12. When the overall size formed by the fixed bracket 11 and the moving bracket 12 becomes larger, the first part of the flexible screen 4 exposed adapts to the increased area of the first body 1, so that the display part of the flexible screen 4 can be increased. When the overall size formed by the fixed bracket 11 and the moving bracket 12 becomes smaller, the exposed part of the flexible screen 4 adapts to the reduced area of the first body 1, so that the display part of the flexible screen 4 can be reduced. By the movement of the moving bracket 12 relative to the fixed bracket 11, when the area of the first body 1 is reduced, the area of the first body 1 can be adapted to the second body 2, which is convenient for carrying; by the movement of the moving bracket 12 relative to the fixed bracket 11, when the area of the first body 1 is larger than the area of the second body 2, the area of the first body 1 increases, and the display size of the display screen can be increased. The flexible screen 4 can be rolled in and out through the movement structure to make the display area smaller or larger, which is convenient for people to use. Optionally, the first part of the flexible screen 4 is connected to the moving bracket 12. Optionally, the first part of the flexible screen 4 is bonded to the moving bracket 12.

[0058] The fixed bracket 11 is provided with a second pulley 111; the first end 521 of the tension rope 52 bypasses the second pulley 111 and is connected to the moving bracket 12. After the tension rope 52 bypasses the sliding member 51 (the sliding member 51 or the first pulley 511 or the movable pulley), the second end 522 of the tension rope 52 is connected to the second edge 42 of the flexible screen 4; the elastic member 53 is arranged between the sliding member 51 and the second body 2. When the moving bracket 12 in the first body 1 moves relative to the fixed bracket 11, the tension rope 52 can move around the second pulley 111 and the sliding member 51 (or the first pulley 511 or the movable pulley), so that when the first edge of the flexible screen 4 moves, the displacement amount of the movement of the second edge 42 of the flexible screen 4 can be compensated. When the tension rope 52 moves in the area between the first pulley 511 and the sliding member 51 (the sliding member 51 or the first pulley 511 or the movable pulley), the elastic force of the elastic member 53 enables the tension rope 52 to provide a tension force for the flexible screen 4. The first edge is affected by the acting force of the moving bracket 12, and the second edge 42 is affected by the acting force of the tension rope 52. The second edge 42 of the flexible screen 4 is pulled by the tension rope 52 and the elastic member 53. The flexible screen 4 is affected by the pulling force of the tension rope 52 and the elastic member 53. Since the elastic member 53 has elasticity, it can undergo elastic deformation, so that the flexible screen 4 is kept slightly taut to maintain flatness and reduce the possibility of folding of the flexible screen 4.

[0059] In some specific embodiments, the tensioning mechanism includes an elastic element. One end of the elastic element is connected to the second edge 42, and the other end is connected to the second body 2. The elastic element can be a component with elasticity or a device made of elastic material. By fixing one end of the elastic element to the second body 2 and pulling the second edge 42 of the flexible screen 4 with the other end, since the elastic element can undergo elastic deformation, the flexible screen 4 can be kept slightly taut to maintain flatness, reducing the possibility of folding of the flexible screen 4.

[0060] In some specific embodiments, the electronic device further includes a rotating unit and a fixing unit. The rotating unit includes a rotating part 7, and the rotating part 7 is configured to rotate according to the movement of the flexible screen 4; the fixing unit is disposed on the second body 2 and is used to define the rotation axis of the rotating part 7. The rotating part 7 can be a rotating shaft structure. By rotating, it can assist in the winding in and out of the flexible screen 4, realizing an increase or decrease in the size of the visible part of the flexible screen 4. The flexible screen 4 bypasses the rotating part 7. By bypassing the rotating part 7, a visible part and an invisible part are formed. The invisible part is the second part of the flexible screen 4, and the visible part is the first part of the flexible screen 4.

[0061] In some specific embodiments, the second body 2 is provided with a first guide wheel 61 and a second guide wheel 62; the tension rope 52 is sequentially wound around the first guide wheel 61 and the second guide wheel 62; in a state where the first body 1 and the second body 2 are folded with each other, the part of the tension rope 52 located on the first body 1 is parallel to the part of the tension rope 52 located on the second body 2. In this embodiment, the part of the tension rope 52 located on the first body 1 can be parallel to the first part of the flexible screen 4, and the part of the tension rope 52 located on the second body 2 can be parallel to the second part of the flexible screen 4.

[0062] In some specific embodiments, a third guide wheel 63 is provided on the second body 2, and the tension rope 52 is disposed between the second guide wheel 62 and the third guide wheel 63, which can guide the tension rope 52 when the first body 1 is unfolded relative to the second body 2. The tensioning mechanism includes a sliding member 51, a tension rope 52, and an elastic member 53. The sliding member 51 is slidably disposed on the second body 2; the first end 521 of the tension rope 52 is connected to the first body 1, and after the tension rope 52 bypasses the sliding member 51, the second end 522 of the tension rope 52 is connected to the second edge 42; the elastic member 53 is disposed between the sliding member 51 and the second body 2, so that when the first body 1 rotates relative to the second body 2, the elastic force of the elastic member 53 enables the tension rope 52 to provide a tensioning force for the flexible screen 4. When the first body 1 is unfolded relative to the second body 2, the sliding member 51 compresses the elastic member 53, and when the first body 1 is folded relative to the second body 2, the sliding member 51 resets. The second edge 42 of the flexible screen 4 is pulled by the tension rope 52 and the elastic member 53, and the flexible screen 4 is subjected to the pulling force of the tension rope 52 and the elastic member 53. Since the elastic member 53 has elasticity, it can undergo elastic deformation, so that the flexible screen 4 is kept slightly taut to maintain flatness and reduce the possibility of folding of the flexible screen 4.
