[0067] In one embodiment, the ends of the first transmission rope 33 and the second transmission rope 34 connected to the second shell 20 can be connected through a first connecting member to form a second connecting end A, and connected to the second shell 20 through the first connecting member.

[0068] The flexible display screen 50 is mounted on the first shell 10 and the second shell 20, and the first end 52 of the flexible display screen 50 is connected to the second end plate 24 of the second shell 20, and covers the side of the second inner surface 212 of the second shell 20 provided with the (second receiving groove 215). The back of the flexible display screen 50 faces the second receiving groove 215, and a support plate can be provided at the notch of the second receiving groove 215 to support the flexible display screen 50. The first shell 10 and the second shell 20 are stacked, and the second shell 20 is inserted into the first receiving groove 113 of the first shell 10. The flexible display screen 50 bypasses the end of the first shell 10 facing away from the second shell 20 and covers the first outer surface 111, and the second end 53 of the flexible display screen 50 is located on the side of the first shell 10 facing away from the second shell 20, and the second end 53 of the flexible display screen 50 is connected to the first transmission rope 33 and the second transmission rope 34; that is, the end of the first transmission rope 33 bypassing the first transmission wheel 31 and the end of the second transmission rope 34 away from the second transmission wheel 32 are both fixedly connected to the flexible display screen 50. The end where the first transmission rope 33 and the second transmission rope 34 are connected to the flexible display screen 50 is the first connection end B of the transmission rope. At this time, the first shell 10 and the second shell 20 are closed, the flexible display screen 50 is folded, the first transmission rope 33 and the second transmission rope 34 remain in a tensioned state, and the first transmission rope 33, the second transmission rope 34, the first transmission wheel 31 and the second transmission wheel 32 are blocked between the first side plate 12 and the second side plate 22 (located in the gap C). The first end 52 and the second end 53 of the flexible display screen 50 can be relative or misaligned in the thickness direction of the electronic device. The projections of the two parts of the flexible display screen 50 after folding in the thickness direction of the electronic device 1000 overlap. It can be understood that after the flexible display screen 50 is folded, the length dimension located on the side of the first shell facing away from the second shell is close to half of the total length of the flexible display screen (the size of the folded part connected to the end plate 13 is smaller). In the figure, L1 is the length of the flexible display screen 50 located in the first shell 10. It should be noted that any size-related characteristics are allowed to have a certain tolerance range as long as it does not affect the actual design and application.

[0069] In one embodiment, the ends of the first transmission rope 33 and the second transmission rope 34 connected to the flexible display screen 50 are connected with a second connecting member and form a first connecting section B, and the flexible display screen 50 can be connected first through the second connecting member.

[0070] like Figure 2When the electronic device 1000 is carried, the first shell 10 and the second shell 20 are stacked, that is, in a closed state. Or when making or receiving a call and operating part of the screen, the first shell 10 and the second shell 20 are in a closed state. The second shell 20 is accommodated in the first receiving groove 113 of the first shell 10, and one end of the first shell 10 abuts against the abutting side 241 of the second shell 20. The first inner surface 112 of the first shell 10 and the second inner surface 212 of the second shell 20 face the same direction and overlap, the first shell 10 covers the second outer surface 211 of the second shell 20, and the first plate 11 and the second plate 21 are stacked. The display surface 51 of the flexible display screen 50 faces away from the first shell 10 and the second shell 20. The flexible display screen 50 is folded into two parts (excluding the folded part covering the end plate 13), one part covers one side of the first inner surface 112 of the first shell 10 and one side of the second inner surface 212 of the second shell 20, that is, the front of the electronic device 1000, and the other part bypasses the end of the first shell 10 to cover the first outer surface 111, that is, the back of the electronic device 1000. At this time, the electronic device 1000 has a small overall size and is easy to use.

[0071] See also Fig. 9 and Fig.10 , Fig. 9 for Figure 1 A schematic diagram of the structure of the electronic device in an unfolded state is shown, wherein the flexible display screen is not shown; Fig.10 for Figure 2 The schematic plan view of an electronic device in an unfolded state at an angle is shown.

[0072] When the electronic device 1000 requires a large-screen display, the first shell 10 and the second shell 20 are unfolded, the first shell 10 slides relative to the second shell 20 and moves away from the second shell 20, the first shell 10 drives the first transmission wheel 31 and the second transmission wheel 32 to slide along the second side plate 22 of the second shell 20 toward the second end plate 24, and the sliding ends 313 of the first transmission wheel 31 and the second transmission wheel 32 located on the first shell 10 slide along the sliding surface 222 of the second side plate 22 of the second shell 20. Since the first transmission rope 33 and the second transmission rope 34 are respectively fixed to the flexible display screen 50 and the second shell 20, the second transmission wheel 32 can pull the second transmission rope 34 to move as the first shell 10 slides, and the second transmission rope 34 rotates around the second transmission wheel 32. At the same time, the part of the flexible display screen 50 covering the first shell 10 will be pulled by the second transmission rope 34, and move along the first outer surface 111 of the first shell 10 away from the second shell 20. At the same time, the first shell 10 is also moving, and the moving flexible display screen 50 goes around the side of the first shell 10 facing away from the first outer surface 111, covering the part of the first shell 10 away from the second shell 20, while the part of the flexible display screen 50 originally covering the second shell does not move. It can be understood that the distance moved by the first shell 10 is the distance L2 that the flexible display screen 50 moves along the first shell 10 and the second transmission rope 34. At the same time, the first transmission rope 33 rotates around the first transmission wheel 31, that is, the first housing 10 slides away from the second housing 20, and the first transmission rope 33 and the second transmission rope 34 move counterclockwise, and the moving distance is the length of the first housing plus the moving distance of the first housing. The positions where the first transmission rope 33 and the second transmission rope 34 are fixed to the second housing 20 are always immovable. In fact, when the first housing 10 moves relative to the second housing 20, the end of the first housing 10 will also generate a driving force on the flexible display screen 50, so that the flexible display screen 50 moves.

[0073] When the first shell 10 slides relative to the second shell 20 until the first shell 10 and the second shell 20 are side by side, the first shell 10 and the second shell 20 are held by the stopper to prevent the first shell 10 and the second shell 20 from being separated. The second transmission wheel 32 is away from the second shell 20, the first transmission wheel 31 is located at the second end plate 24 of the second shell 20, which is also the connection point between the first shell 10 and the second shell 20, the first transmission rope 33 and the second transmission rope 34 are swapped, the first transmission rope 33 is located on one side of the first outer surface 111, and the second transmission rope 34 is located on one side of the first inner surface 112. The flexible display screen 50 is unfolded as the first shell 10 slides, and the length dimension after unfolding is greater than the closed dimension of the first shell and the second shell, and covers the first shell 10 (on the first inner surface 112 side) and the second shell 20 (on the second inner surface 212 side) at the same time. The position where the flexible display screen 50 is fixed with the first transmission rope 33 and the second transmission rope 34 will move to the position where the second side plate 22 of the second shell 20 is close to the second end plate 24, that is, the second transmission wheel 32 is close to the second end plate 24. In this process, the total distance moved by the first transmission rope 33 and the second transmission rope 34 is the length of the first transmission rope 33 and the second transmission rope 34 plus the sliding distance of the first housing 10 relative to the second housing 20; the sliding distance of the first housing 10 is the length of the first transmission rope 33, or is equal to the width of the first housing 10. In other embodiments, the sliding distance of the first housing 10 relative to the second housing 20 is greater than half of the width of the first housing 10 in the sliding direction.

[0074] In this embodiment, when the first shell 10 of the electronic device 1000 moves, it will drive the transmission rope and the transmission wheel to move, and the transmission rope itself is also moving. The actual length of the transmission rope is roughly the width of the first shell 10 or the second shell 20, and the moving distance is twice the length of the transmission rope. The first shell 10 can be completely pulled out relative to the second shell 20, and the flexible display screen 50 can be driven at a multiple speed, so that the flexible display screen 50 can be unfolded, and the unfolded size is a certain distance L2, and L2 is greater than half L1. Compared with the prior art pull-out structure, which cannot realize the screen unfolding by completely pulling out the first shell 10 relative to the second shell 20, the flexible display screen 50 of this embodiment is also unfolded when the first shell 10 is completely pulled out, which can realize the performance of a large screen and improve the competitiveness and performance of the electronic device 1000. Among them, the part of the flexible display screen connected to the first connection end is wound around the end plate 13, and the part of the flexible display screen located on the cover of the first shell facing away from the second shell is all transmitted to the side of the outer surface facing away from the first shell, that is, the part greater than half L1.

[0075] See also Fig.11In another embodiment of the present application, the transmission part 30 includes a transmission rope 35 and a transmission wheel 36. The transmission wheel is fixed to an end of the first side plate 12 of the first shell 10 away from the end plate; that is, the side with an open end. The transmission rope 35 includes a first connecting end B and a second connecting end A opposite to each other, the second connecting end A is fixed to the second side plate 22 of the second shell 20, and the first connecting end B is fixed to the end of the flexible display screen 50 around the transmission wheel 36. When the first shell 10 and the second shell 20 are closed, the transmission rope 35 is in a tensioned state, and the transmission wheel 36 is located in a direction away from the first shell 10 and away from the sliding direction of the second shell 20. The first shell 10 slides relative to the second shell 20, and the transmission wheel 36 moves with the first shell 10. The first shell 10 generates a driving force on the flexible display screen 50, which causes the part of the flexible display screen 50 located on the first outer surface 111 to move with the first shell 10 and relative to the first shell 10. When the first shell 10 and the second shell 20 are side by side, the flexible display screen 50 is fully unfolded, and the transmission rope 35 is in a relaxed state. During this process, the transmission rope 35 and the transmission wheel 36 are pulled by the flexible display screen 50 to the second end plate 24 of the second housing 20. When the first housing 10 and the second housing 20 are closed, the first housing 10 slides toward the second housing 20, driving the transmission wheel 36 to move, and the movement of the transmission wheel 36 pulls the transmission rope 35 to move to a tensioned state, thereby causing the transmission rope 35 to pull the flexible display screen 50 to cover the first outer surface 111 of the first housing 10 again. It can be understood that the transmission rope 35 of this embodiment is the transmission rope 33 of the previous embodiment.

[0076] In another embodiment of the present application, the electronic device 1000 further includes a main housing (not shown), and the main housing is connected to one side of the mating end plate 23 of the second housing 20. The specific connection may be a rotational connection. For example, the electronic device 1000 of the present embodiment is a laptop or a foldable handheld computer, and the main housing may be a host computer with a keyboard. After the second housing 20 and the first housing 10 are closed, they can be rotated relative to the host and object and stacked with the main housing. The main housing has a recessed portion for accommodating the first housing 10 and the second housing 20. The first housing 10 and the second housing 20 are opened relative to the main housing, and the first housing 10 and the second housing 20 are unfolded, and the flexible display screen 50 is flattened to form a display screen of the handheld computer. The first housing 10 and the second housing 20 can be closed to facilitate the carrying of the electronic device 1000.
