[0028] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0029] Taking advantage of the bendable and foldable effects of flexible display screens, display devices with sliding structures have become an innovative application field, allowing users to adjust the display area of ​​the flexible display screen at will according to their needs. This not only makes it convenient for users to carry it with them, but also provides users with a better experience effect. It is an important direction for the development of electronic equipment.

[0030] Figure 1 to Figure 5 An embodiment of the electronic device of the present invention is shown. It should be noted that the electronic device in the present application is a mobile terminal, which may include a mobile phone, a laptop computer, a personal digital assistant, etc. In this embodiment, only a laptop computer is used as an example for description. The electronic device includes a first housing 10, a second housing 20, a flexible display screen 30, an elastic element 40 and a transmission mechanism.

[0031] The first housing 10 is provided with a housing space, and its material can be aluminum alloy or plastic, etc., which is not specifically limited here. The housing space in the first housing 10 accommodates input components, such as a keyboard and a touchpad, etc., and the input components are used to receive input commands from the user. The housing space also accommodates other functional components such as a motherboard, a storage device and a battery, so that the electronic device can receive input commands, perform calculations and output calculation results.

[0032] The second housing 20 includes a fixed portion 21 and a movable portion 22. The movable portion 22 can move relative to the fixed portion 21. The fixed portion 21 is rotatably connected to the first housing 10. The fixed portion 21 has a first supporting surface 211. The movable portion 22 is disposed on one side of the fixed portion 21 and can move toward or away from the fixed portion 21.

[0033] At least a portion of the flexible display screen 30 covers the first support surface 211, and one end of the flexible display screen 30 is fixedly connected to the first support surface 211, and the other end of the flexible display screen 30 bypasses the edge of the moving part 22 and is located on the opposite side of the first support surface 211. The flexible display screen 30 can be expanded or contracted as the moving part 22 moves.

[0034] Specifically, when the movable portion 22 moves in a direction away from the fixed portion 21, the flexible display screen 30 located on the side opposite to the first supporting surface 211 bypasses the edge of the movable portion 22 to the side of the first supporting surface 211, so that the area of ​​the visible area is increased, that is, the unfolding effect of the flexible display screen 30 is achieved.

[0035] When the movable portion 22 moves toward the direction approaching the fixed portion 21, the flexible display screen 30 located on one side of the first supporting surface 211 bypasses the edge of the movable portion 22 to the opposite side of the first supporting surface 211, so that the area of ​​the visible area is reduced, that is, the shrinking effect of the flexible display screen 30 is achieved.

[0036] The elastic element 40 is located in the second housing 20, and the two ends of the elastic element 40 are respectively connected to the fixed portion 21 and the other end of the flexible display screen 30. The elastic element 40 is used to apply tension to the flexible display screen to ensure that the flexible display screen 30 is closely attached to the edge of the movable portion 22 and the first support surface 211. Specifically, the elastic element 40 can be configured as a plurality of tension springs, the two ends of which are respectively connected to the fixed portion 21 and the other end of the flexible display screen 30. When the movable portion 22 moves toward the direction close to the fixed portion 21, the tension spring can also pull the flexible display screen 30 back to the opposite side of the first support surface 211, so as to provide a contraction force for the flexible display screen 30.

[0037] The transmission mechanism is configured to respond to the rotation of the second shell 20 relative to the first shell 10 so that the moving part 22 moves relative to the fixed part 21. Specifically, when the user lifts up the second shell 20, that is, when the second shell 20 and the first shell 10 are unfolded, the transmission mechanism can drive the moving part 22 to move in a direction away from the fixed part 21, so that when the user lifts up the second shell 20, the visible area of ​​the flexible display screen 30 is increased. When the user closes the second shell 20, that is, when the second shell 20 and the first shell 10 are folded together, the transmission mechanism can drive the moving part 22 to move in a direction close to the fixed part 21, so that when the user closes the second shell 20, the visible area of ​​the flexible display screen 30 is reduced, thereby reducing the area of ​​the second shell 20. It can be understood that the display control module can dynamically adjust the resolution of the visible area so that the resolution is adapted to the visible area. For example, as the lifting angle of the second shell 20 increases, the visible area of ​​the flexible display screen 30 increases, and the resolution of the visible area increases. Conversely, as the lifting angle of the second shell 20 decreases, the visible area of ​​the flexible display screen 30 decreases, and the resolution of the visible area also decreases accordingly.

[0038] It should be noted that the transmission mechanism transmits the force applied by the user to lift or close the second housing 20 to the moving part 22, so that the moving part 22 moves in a direction away from or close to the fixed part 21. In other words, the transmission mechanism only transmits the force applied by the user to the second housing 20 to the moving part 22 to drive the moving part 22 to move. The transmission mechanism itself does not generate power, and the force to drive the moving part 22 to move is provided by the user.

[0039] The electronic device of the embodiment of the present invention is a folding structure, and the second shell 20 is rotatably connected to the first shell 10. When carrying, the second shell 20 is folded together with the first shell 10. When in use, the force of the user rotating the second shell 20 is transmitted to the moving part 22 through the transmission mechanism to drive the moving part 22 to move in a direction away from or close to the fixed part 21, thereby increasing or reducing the visible area of ​​the flexible display screen 30, and then when the second shell 20 and the first shell 10 are folded, the area of ​​the second shell 20 is reduced, the overall volume of the electronic device is reduced, and it is convenient for the user to carry. At the same time, when the second shell 20 and the first shell 10 are unfolded, the area of ​​the second shell 20 is increased, the display area of ​​the flexible display screen 30 is increased, and the user's experience is improved. The electronic device of the present invention does not need to set a separate power source for the sliding and rolling action of the flexible display screen 30, and the sliding and rolling of the flexible display screen 30 can be achieved only by the action of the user lifting or closing the second shell 20, so that the structure of the electronic device is simple and the production cost is reduced.

[0040] like Figure 1As shown in the exploded structural diagram, the fixed portion 21 is rotatably connected to the first housing 10 via a rotating shaft 212, the rotating shaft 212 is arranged at the bottom edge of the fixed portion 21, and the movable portion 22 is arranged at the top of the fixed portion 21, that is, the movable portion 22 is arranged on the side of the fixed portion 21 away from the rotating shaft 212, and the movable portion 22 can move in a direction away from or close to the rotating shaft 212. Figure 1 In the direction shown, when the movable part 22 moves in the direction away from the rotating shaft 212, the flexible display screen 30 flipped from the top edge of the movable part 22 to the side of the first supporting surface 211 is an enlarged visible area, thereby increasing the visible area of ​​the flexible display screen 30 in the height direction.

[0041] Combination Figure 2 to Figure 4 As shown, the transmission mechanism includes a first gear 51, a second gear 52, a connecting rod 53 and a sleeve 54. The first gear 51 is fixedly arranged on the first housing 10. Specifically, an opening is provided at an edge of one side of the first housing 10 close to the second housing 20. The first gear 51 is arranged in the opening and is fixedly connected to the first housing 10, that is, the first gear 51 always remains in a fixed state and cannot rotate relative to the first housing 10.

[0042] The second gear 52 is rotatably disposed on the fixing portion 21. Specifically, an opening is also provided on a side edge of the fixing portion 21 of the second housing 20 close to the first housing 10. The second gear 52 is rotatably disposed in the opening, and the second gear 52 is meshed with the first gear 51, so that when the second housing 20 rotates relative to the first housing 10, the second gear 52 can rotate. That is, when the second housing 20 rotates relative to the first housing 10 through the rotating shaft 212, the second gear 52 moves along the outer peripheral surface of the first gear 51, and through the meshing state between the two, the second gear 52 rotates around its own axis.

[0043] The second gear 52 is used to drive the connecting rod 53 to rotate. The sleeve 54 is connected to the connecting rod 53 through a thread so that when the connecting rod 53 rotates, the sleeve 54 can reciprocate along the outer circumference of the connecting rod 53. The sleeve 54 is connected to the moving part 22, thereby driving the moving part 22 to reciprocate.

[0044] Specifically, a first bevel gear portion 521 is provided on one side surface of the second gear 52, and a second bevel gear portion 531 is provided at the end of the connecting rod 53. Through the meshing of the first bevel gear portion 521 and the second bevel gear portion 531, the second gear 52 can drive the connecting rod 53 to rotate, and the rotation axes of the second gear 52 and the connecting rod 53 are perpendicular to each other. The diameter of the first bevel gear portion 521 is smaller than the diameter of the second gear 52, so as to increase the torque transmitted to the connecting rod 53 and ensure that the moving part 22 can move. The sleeve 54 is sleeved on the outer circumference of the connecting rod 53, that is, one end of the connecting rod 53 is inserted into the sleeve 54 and connected to the sleeve 54 through a thread. When the connecting rod 53 rotates around its axis, the sleeve 54 moves along the outer circumference of the connecting rod 53 through the thread. For example, when the user lifts the second shell 20, the sleeve 54 moves along the outer circumference of the connecting rod 53 in a direction away from the second gear 52, thereby driving the moving part 22 to move in a direction away from the fixed part 21.

[0045] In this embodiment, the sleeve 54 is connected to the moving part 22 through a thread, that is, a thread 541 is also provided on the outer surface of the sleeve 54, and the sleeve 54 is screwed into the moving part 22 through the thread 541, and the position of the moving part 22 relative to the fixed part 21 can be adjusted by the depth of screwing into the moving part 22, so as to adjust the visible area of ​​the flexible display screen 30. After the relative position of the moving part 22 and the sleeve 54 is adjusted, the two can be tightened to ensure that the relative position between the moving part 22 and the sleeve 54 is fixed.

[0046] In this embodiment, two transmission mechanisms are provided, which are symmetrically arranged on both sides of the moving part 22, so that the moving part 22 can move smoothly. Specifically, the first gear 51, the second gear 52, the connecting rod 53 and the sleeve 54 are each provided with two, and the two sleeves 54 are respectively connected to the two ends of the moving part 22, and jointly drive the moving part 22 to move.

[0047] Combination Figure 1 , Figure 2 and Figure 5 As shown, a receiving space is formed inside the fixed portion 21 in this embodiment, and at least a part of the structure of the movable portion 22 is located in the receiving space and can slide out of and into the receiving space.

[0048] Specifically, the fixed part 21 is generally a box-shaped structure with an open top, and part of the structure of the movable part 22 enters the inside of the fixed part 21 from the top. One side surface of the fixed part 21 is formed as a first supporting surface 211, and the top edge of the first supporting surface 211 is recessed inward to form a plurality of openings 213, so that part of the first supporting surface 211 forms a comb-tooth structure. Preferably, the first supporting surface 211 is slightly lower than the surface of the fixed part 21, and when the flexible display screen 30 covers the first supporting surface 211, the surface of the flexible display screen 30 is flush with the surface of the fixed part 21. Sleeve parts 214 are also provided on both sides of the fixed part 21, and the sleeve 54 and the connecting rod 53 are accommodated in the sleeve part 214.

[0049] The moving part 22 is set to be in the shape of a flat plate, and a plurality of mutually parallel grooves 221 are provided on one side surface of the moving part 22. When the moving part 22 is located in the fixed part 21, the comb-tooth structures of the first supporting surface 211 are respectively located in the grooves 221, so that the moving part 22 can slide along the comb-tooth structure. Further, the surface between the plurality of grooves 221 forms a second supporting surface 222 on the moving part 22, and the second supporting surface 222 is flush with the height of the first supporting surface 211, that is, the depth of the groove 221 is equal to the thickness of the comb-tooth structure, and the comb-tooth structure is attached to the bottom surface of the groove 221, and the first supporting surface 211 and the second supporting surface 222 are located on the same plane. The flexible display screen 30 covers the first supporting surface 211 and the second supporting surface 22, and the two play the role of jointly supporting the flexible display screen 30.

[0050] It should be noted that the other end of the flexible display screen 30 bypasses the top of the moving part 22 and is located on the back side of the moving part 22 , and the other end of the flexible display screen 30 is also located inside the fixed part 21 .

[0051] Please refer to Figure 2 As shown, the shapes of the edge portions 223 on both sides of the moving part 22 correspond to the shape of the sleeve portion 214. The edge portions 223 are inserted into the sleeve portion 214, so that the moving part 22 can slide along the sleeve portion 214, so that the edge portions 223 and the sleeve portion 214 can play a role of sliding guide. The top edge of the moving part 22 is set in an arc shape, so that the flexible display screen 30 can slide smoothly from the back of the moving part 22 to the second supporting surface 222, avoiding damage to the flexible display screen 30.

[0052] In some embodiments, a scroll is provided at the top edge of the movable part 22, and the scroll is rotatably connected to the movable part 22. The middle part of the flexible display screen 30 is wound around the scroll, that is, the flexible display screen 30 is wound to the back side of the movable part 22 through the scroll. This structure can make the flexible display screen 30 slide more smoothly and reduce the friction between the flexible display screen 30 and the movable part 22.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
