Referring to fig. 1 to 4, an electronic device 100 is provided in an embodiment of the present application, and the electronic device 100 includes a housing assembly 10, a flexible display 20 and a driving module 30. The housing assembly 10 includes a first shell 11 and a second shell 12 that are slidably connected.

In the electronic device 100 of the embodiment of the present application, the extension portion 22 can be hidden in the housing assembly 10, the driving device 31 can drive the second shell 12 to slide relative to the first shell 11 through the transmission assembly 32, so that the extension portion 22 can be unfolded or retracted into the housing assembly 10 to adjust the display area of the electronic device, and the front projection of the driving device 31 on the flat portion 21 and the front projection of the extension portion 22 on the flat portion 21 are offset from each other. In this way, the driving device 31 and the flat portion 21 may be installed in the housing assembly 10 in a staggered manner, and the driving device 31 is installed outside the overlapping area of the extension portion 22 and the flat portion 21 of the flexible display screen 20, so that the driving device (such as a motor) in the electronic device 100 can avoid the extension portion hidden in the housing assembly 10, and the stacking thickness is effectively reduced, so that the electronic device 100 is lighter and thinner, and the user experience is improved.

Referring to fig. 2 and 3, the electronic device 100 in the embodiment of the present application may include two modes. The first configuration is a configuration in which the first case 11 and the second case 12 are fitted together (as shown in fig. 1), that is, a configuration in which the electronic device 100 is located when the first case 11 and the second case 12 are close to each other and move to the limit position, in which the flat portion 21 of the flexible display 20 is exposed outside the case assembly 10, the extension 22 is substantially completely hidden inside the case assembly 10, and the electronic device 100 has a small display area and is convenient to carry. The second configuration is a configuration in which the second casing 12 moves away from the first casing 11 to gradually spread the expansion portion 22 of the flexible display 20 out of the housing assembly 10 (see fig. 2), and in the second configuration, the second portion of the flexible display 20 is at least partially spread out of the housing assembly 10 to form a display portion of the electronic device 100 together with the flat portion 21, so that a display area of the electronic device 100 is larger, and a better display effect is provided for a user.

In the present embodiment, "display area" refers to the area of the portion of the flexible display screen 20 that is exposed outside the housing assembly 10 for display.

It should be noted that, in the embodiment of the present application, the extension portion 22 can be hidden in the housing assembly 10, it is understood that the extension portion 22 can be received in the inner space of the housing assembly 10 and not exposed, or the extension portion 22 can be hidden in the rear surface of the housing assembly 10 and exposed from the rear surface, and herein, the extension portion 22 can be received in the inner space of the housing assembly 10 and not exposed is described as an example.

It will be appreciated that the driving device 31 is mounted in the first housing 11 to drive the second housing 12 to move relative to the first housing 11, and the second housing 12 can move relative to the first housing 11 to move the flexible display 20, so that the electronic device 100 can be switched between two modes. In some embodiments, the first case 11 in the electronic device 100 may serve as a main body supporting structure of the electronic device 100, and the driving module 30, the speaker, the circuit board, the battery, and the like may be accommodated inside the first case 11. In addition, in some embodiments, the second shell 12 may be slightly smaller than the first shell 11, such that the second shell 12 may also be entirely retracted inside the first shell 11. In some embodiments, the first and

second shells

11, 12 may have similar shapes, and the second shell 12 cooperates with the first shell 11 to form a complete support structure, while allowing for a symmetrical aesthetic appearance of the flexible display 20 after deployment.

In particular, in the illustrated embodiment, the first casing 11 is slidably connected to the second casing 12, and the expansion portion 22 of the flexible display 20 may be disposed inside the casing assembly 10, belonging to a hidden structure. Referring to fig. 3, in a first configuration, the extended portion 22 of the flexible display 20 is not used for display and only the flattened portion 21 is used for display. Upon a separation movement of the second housing 12 relative to the first housing 11, the flexible display 20 may be moved such that the extension 22 of the flexible display 20 is at least partially pulled out of the housing assembly 10 to switch to the second configuration. In the second configuration, the extension 22 is at least partially pulled out of the housing assembly 10, and the flat portion 21 and the extension 22 are simultaneously used for display, thereby changing the display area of the electronic device 100. During the switching of these two modes, the driving means 31 are used to provide a driving force, and the transmission assembly 32 is used to transmit the driving force to the housing assembly 10, so that the second shell 12 moves relative to the first shell 11, and the expansion portion 22 is at least partially deployed outside the housing assembly 10 or retracted inside the housing assembly 10.

In the embodiment of the application, the flat portion 21 and the extension portion 22 of the flexible display screen 20 are arranged in a U shape, and the front projection of the driving device 31 on the flat portion 21 and the front projection of the extension portion 22 on the flat portion 21 are offset from each other, so that the problem that the thickness of the electronic device 100 is increased due to the driving device 31 being arranged between the overlapping portions of the flat portion 21 and the extension portion 22 is avoided, and the electronic device 100 can be made lighter and thinner. It is appreciated that the saved space can be used to reduce the overall size of the electronic device 100, so that the electronic device 100 is more compact and slim. In some embodiments, the saved space may be used to increase the battery accommodation, so that the electronic device 100 is used for a longer time, and the user experience is improved.

In the embodiment of the present application, the front projection of the driving device 31 on the flat portion 21 and the front projection of the extension portion 22 on the flat portion 21 are offset from each other, which means that no overlapping area exists between the front projections of the driving device 31 and the extension portion 22 on the flat portion 21, or only overlapping boundaries, regardless of whether the electronic device 100 is in the first configuration or the second configuration.

The electronic device 100 in this embodiment of the present application may be a mobile terminal device such as a smart phone or a tablet computer, or may be a device that can be equipped with a display device, such as a game device, a car-mounted computer, a notebook computer, or a video player, and is not specifically shown here.

Furthermore, in the description of embodiments of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

It should be noted that in the description of the present application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application. Furthermore, it should be noted that in the description of the present application, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

Referring to fig. 3 to 5, in some embodiments, the driving device 31 includes a motor 311, where the motor 311 is connected to the transmission assembly 32, and the motor 311 is configured to drive the second shell 12 to slide relative to the first shell 11 through the transmission assembly 32, and an orthographic projection of the motor 311 on the flat portion 21 and an orthographic projection of the extension portion 22 on the flat portion 21 are offset from each other.

In this way, the thickness of the electronic device 100 is prevented from being increased due to the arrangement of the motor 311 between the flexible display screens 20, so that the space distribution of the electronic device 100 is more reasonable, and the electronic device 100 is lighter and thinner.

Further, referring to fig. 3-5, in some embodiments, the driving device 31 further includes a gear set 312, and the gear set 312 is connected to the motor 311 and the transmission assembly 32. The front projection of the gear set 312 on the flat portion 21 and the front projection of the extension portion 22 on the flat portion 21 are offset from each other; or the front projection of gear set 312 on flat portion 21 at least partially overlaps the front projection of extension 22 on flat portion 21.

In this way, the gear set 312 may be at least partially disposed outside the flexible display 20, so as to further optimize the space allocation of the motor device 100, and make the electronic device 100 lighter and thinner.

In particular, in some embodiments, the motor 311 may be only maintained in a position in which its front projection on the flat portion 21 and its front projection on the flat portion 21 of the extension portion 22 are offset from each other, and the specific position of the gear set 312 need not be limited, but only the gear set 312 need be ensured to be disposed in the first housing 11 to connect the motor 311 and the transmission assembly 32.

In some embodiments, gear set 312 may be maintained in a position where its front projection on flat portion 21 is offset from the front projection of extension 22 on flat portion 21; or the front projection of the gear set 312 on the flat portion 21 and the front projection of the extension portion 22 on the flat portion 21 at least partially overlap, the specific position of the motor 311 need not be limited, and only the motor 311 is ensured to be disposed in the first housing 11 so that the motor 311 can provide driving force.

In some embodiments, it is ensured that the motor 311 is disposed in a position in which its front projection on the flat portion 21 is offset from the front projection of the extension portion 22 on the flat portion 21. In turn, the gear set 312 is maintained in a position in which its front projection on the flat portion 21 is offset from the front projection of the extension portion 22 on the flat portion 21; or the front projection of gear set 312 on flat portion 21 at least partially overlaps the front projection of extension 22 on flat portion 21.

Referring to fig. 4 to 7, in some embodiments, the transmission assembly 32 includes a rotating member 321 and a moving member 322, the rotating member 321 is rotatably disposed on the first housing 11 and connected to the gear set 312, the moving member 322 is screwed to the rotating member 321 and fixedly connected to the second housing 12. When the motor 311 drives the rotating member 321 to rotate through the gear set 312, the rotating member 321 can drive the moving member 322 to move on the rotating member 321 along the axial direction of the rotating member 321 so as to drive the second shell 12 to slide relative to the first shell 11.

In this way, when the rotating member rotates, the moving member 322 can move along the axial direction of the rotating member 321 to drive the second casing 12 to slide relative to the first casing 11, so that the expansion portion 22 is at least partially deployed out of the casing assembly 10 or retracted into the casing assembly 10, and the electronic device 100 can be switched between the first configuration and the second configuration.

Specifically, in one possible embodiment, the rotating member 321 may be a screw, and the moving member 322 may be a nut, thereby forming a screw-nut transmission structure. The motor 311 provides driving force and transmits the driving force to the gear set 312, and the gear set 312 may adjust the rotation speed to an appropriate magnitude and then transmit the rotation to the rotator 321. Thus, when the driving device 31 drives the rotating member 321 to rotate, the rotating member 321 can drive the moving member 322 to move on the rotating member 321, so as to drive the second shell 12 to move relative to the first shell 11. While the flat portion 21 is connected to the first housing 11, thereby enabling the expansion portion 22 to be at least partially unfolded out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100.

Further, taking the rotating member 321 as an example of a screw rod, the rotating member 321 may include a threaded section, and the moving member 322 is sleeved on the threaded section and is in threaded connection with the threaded section, so that when the rotating member 321 rotates one turn along the first direction, the moving member 322 moves a pitch distance on the rotating member 321, so that the second shell 12 slides a pitch distance towards a side far from the first shell 11, and further, a distance from the expansion portion 22 to the housing assembly 10 is obtained to obtain a larger display area of the electronic device 100. When the rotating member 321 rotates one turn in the second direction, the moving member 322 moves reversely by a pitch distance on the rotating member 321, so that the second housing 12 slides by a pitch distance to a side close to the first housing 11, and thus the extended portion 22 is retracted into the housing assembly 10, so as to obtain a smaller display area of the electronic device 100.

Referring to fig. 4 to 8, in some embodiments, a motor shaft of the motor 311 is disposed perpendicular to a rotation axis of the rotating member 321, the gear set 312 includes a reversing gear set 313 and a driving gear set 314, the reversing gear set 313 is connected to the motor shaft of the motor 311 and meshed with the driving gear set 314, the driving gear set 314 is connected to the rotating member 321, and the reversing gear set 313 and the driving gear set 314 can convert the rotation of the motor shaft of the motor 311 into the rotation of the rotating member 321.

In this way, the motor shaft of the motor 311 is perpendicular to the rotation axis of the rotating member 321, so that the space occupied by the driving device 31 and the transmission assembly 32 can be reasonably distributed, and the space utilization rate of the electronic device 100 can be optimized.

Specifically, the driving device 31 and the transmission assembly 32 may be distributed in an L shape, the motor shaft of the motor 311 may be disposed at an end of the first housing 11 away from the second housing 12 along the length direction of the electronic device 100, and the rotating member 321 may be rotatably disposed on the first housing 11 along a direction perpendicular to the motor shaft, or the length direction of the rotating member 321 is a sliding direction of the second housing 12 relative to the first housing 11. The reversing gear set 313 can change the rotation direction of the motor 311, or the steering gear set 312 changes the rotation direction of the gear around the shaft when transmitting the rotation of the motor shaft to the driving gear set 314, so that the driving gear set 314 can be connected with the rotating member 321 to drive the rotating member 321 to rotate. The drive gear set 314 may change the gear rotational speed such that the rotator 321 rotates at the appropriate speed.

Referring to fig. 8 and 9, in some embodiments, the reversing gear set 313 includes a first transmission gear 3131, a reversing shaft 3132, a reversing gear 3133, and a second transmission gear 3134, the first transmission gear 3131 is mounted on a motor shaft of the motor 311, the reversing shaft 3132 is disposed parallel to the rotator 321, the reversing gear 3133 is mounted on the reversing shaft 3132 and is meshed with the first transmission gear 3131, and the second transmission gear 3134 is mounted on the reversing shaft 3132 and is meshed with the transmission gear set 314.

As such, the motor shaft rotation direction can be changed by the first transmission gear 3131, the reversing shaft 3132, the reversing gear 3133, and the second transmission gear 3134, so that the motor 311 can be disposed along the rotation axis perpendicular to the rotator 321, and the space of the electronic device 100 can be reasonably distributed.

Specifically, the first transmission gear 3131 may be mounted on the motor shaft to rotate with the motor shaft, and the first transmission gear 3131 is meshed with the reversing gear 3133 already mounted on the reversing shaft 3132, so that the motor shaft may drive the reversing gear 3133 to rotate through the first transmission gear 3131, and the reversing gear 3133 is mounted on the reversing shaft 3132 to drive the reversing shaft 3132 to rotate. The reversing shaft 3132 is disposed in parallel with the rotator 321 such that the axis of the reversing shaft 3132 is perpendicular to the motor shaft of the motor 311. The reversing shaft 3132 is provided with a second transmission gear 3134, the second transmission gear 3134 can rotate along with the reversing shaft 3132, the second transmission gear 3134 is meshed with the transmission gear set 314 to transmit driving force to the transmission gear set 314, the transmission gear set 314 is connected with the rotating member 321, and the transmission gear set 314 can change the gear rotation speed so that the rotating member 321 rotates at a proper speed. Specifically, in embodiments of the present application, the reversing gear 3113 may be a face gear. In some embodiments, the gears of the drive gear set 314 may be helical gears to reduce noise generated when the gears mesh.

Further, referring to fig. 9, in some embodiments, the motor 311 includes a first motor 3111 and a second motor 3112, the first motor 3111 and the second motor 3112 are disposed in parallel along a sliding direction of the second housing 12, motor shafts of the first motor 3111 and the second motor 3112 are perpendicular to a rotation axis of the rotating member 321, a number of the first transmission gears 3131 is two, two first transmission gears 3131 are connected to motor shafts of the first motor 3111 and motor shafts of the second motor 3112, a number of the reversing gears 3133 is two, and each reversing gear 3133 corresponds to one first transmission gear 3131.

In this way, the first motor 3111 and the second motor 3112 can simultaneously provide driving force to ensure smooth rotation of the rotating member 321, so that the electronic device 100 can be switched between the first mode and the second mode smoothly, and slow opening and closing speeds, or even abnormal opening and closing, caused by insufficient driving force when the second housing 12 moves relative to the first housing 11 are avoided.

Specifically, the motor 311 generates driving force, or the motor 311 rotates a motor shaft under the action of electric power, and the motor shaft is connected with the gear set 312 and drives the gear set 312 to rotate. It will be appreciated that when a single motor 311 cannot provide sufficient driving force, two motors 311 may be used to simultaneously provide driving force, namely a first motor 3111 and a second motor 3112. The first motor 3111 and the second motor 3112 may use the same kind and type of motor 311, for example, the first motor 3111 and the second motor 3112 may be two stepping motors 311 placed side by side, the motor shafts of the first motor 3111 and the motor shafts of the second motor 3112 are perpendicular to the rotation axis of the rotator 321, and the protruding lengths of the two motor shafts are identical, and two first transmission gears 3131 are provided at the same positions of the two motor shafts, respectively. The first motor 3111 and the second motor 3112 may be started and stopped simultaneously, and the driving force is output to the outside at the same power, that is, the motor shaft rotation speeds of the first motor 3111 and the second motor 3112 are the same. Two first transmission gears 3131 are respectively connected to the motor shaft of the first motor 3111 and the motor shaft of the second motor 3112, and two reversing gears 3133 are also provided, which are matched with the first transmission gears 3131, and each reversing gear 3133 corresponds to one first transmission gear 3131. The two reversing gears 3133 are mounted on the same reversing shaft 3132, so that the two motors 311 can simultaneously provide driving force to drive the reversing shaft 3132 to rotate, that is, the reversing shaft 3132 and the two first transmission gears 3131 cooperate to combine the driving forces provided by the two motors 311. The reversing shaft 3132 is further provided with a second transmission gear 3134, and the second transmission gear 3134 meshes with the transmission gear set 314 and transmits driving force to the transmission gear set 314, and the transmission gear set 314 converts the rotation speed into a proper magnitude and transmits the proper rotation speed to the rotating member 321. The rotating member 321 rotates to enable the moving member 322 to move on the rotating member 321, and the moving member 322 is connected with the second casing 12 to drive the second casing 12 to move, so that the expansion portion 22 can be at least partially unfolded out of the casing assembly 10 or retracted into the casing assembly 10, so as to adjust the display area of the electronic device 100.

It can be appreciated that the first motor 3111 and the second motor 3112 are simultaneously connected to one transmission assembly 32, so as to provide driving force for the transmission assembly 32, and further optimize space compared with two motors 31 corresponding to two transmission assemblies 32, so that the saved space can be used for increasing the battery accommodation and the like, and improving user experience.

Referring to fig. 4 and 5, in some embodiments, the electronic device 100 further includes a guide shaft 40, the guide shaft 40 is disposed in the first housing 11 and parallel to the rotating member 321, the guide shaft 40 penetrates the moving member 322, and the moving member 322 can slide on the guide shaft 40.

In this way, the guiding shaft 40 can guide the moving direction of the moving member 322, so that when the rotating member 321 rotates, the moving member 322 can move stably, thereby improving the stability of the movement of the second shell 12 relative to the first shell 11, and avoiding possible jamming.

Specifically, the guide shaft 40 is disposed in the first housing 11 and parallel to the rotating member 321, and at the same time the guide shaft 40 may be disposed at a position closer to the rotating member 321 so that the moving member 322 may be simultaneously penetrated on the guide shaft 40 and the rotating member 321. Thus, when the rotating member 321 rotates, the moving member 322 does not follow the rotating member 321, but moves in the axial direction of the rotating member 321 by the thread segments.

In addition, in some embodiments, the electronic device 100 further includes a connection frame 50, where the connection frame 50 is fixedly connected to the second housing 12 and is movable together with the second housing 12. The moving member 322 may include a protrusion, the coupling frame 50 may include a groove, and the moving member 322 and the coupling frame 50 may move together with the coupling frame 50 by the protrusion and the groove, or the moving member 322 may move the coupling frame 50 to move the second housing 12 with respect to the first housing 11. The connecting frame 50 serves as a place for receiving the force, and can increase the contact area with the second housing 12, so that stress concentration is avoided, and the transmission process of the transmission assembly 32 is more stable.

In one example, the motor 311 generates a driving force, the driving force of the motor 311 transmits the driving force to the rotating member 321 through the reversing gear set 313 and the driving gear set 314, the rotating member 321 rotates such that the moving member 322 moves axially along the rotating member 321, the moving member 322 is connected to the second housing 12 through the connecting frame 50, and thus the second housing 12 moves relative to the first housing 11, such that the second housing 12 drives the expansion portion 22 to be expanded out of the housing assembly 10 or retracted into the housing assembly 10.

Further, in some embodiments, the connecting frame 50 and the rotating member 321 are located in the middle of the housing assembly 10, so that stable transmission can be realized only by matching one group of connecting frame 50 and the transmission assembly 32, and the phenomenon of skew, jamming and the like when the second housing moves relative to the first housing due to the fact that one group of connecting frame 50 and the transmission assembly 32 are arranged in other positions is avoided, and the stability of transmission is improved.

Referring to fig. 8 and 9, in some embodiments, the electronic device 100 further includes a position detecting device 60, where the position detecting device 60 is mounted on the first housing 11, and the position detecting device 60 is configured to detect a rotation angle of the rotating member 321, thereby detecting a relative position between the second housing 12 and the first housing 11.

In this way, the rotation angle of the rotator 321 is detected by the position detecting device 60, and thus the movement stroke between the first case 11 and the second case 12 can be calculated.

Illustratively, the position detecting device 60 may be a potentiometer, which may be used to detect the rotation angle of the rotating member 321, and thus obtain the movement stroke of the moving member 322 through the rotation direction and angle. The potentiometer is at least partially arranged on the rotating member 321 so as to rotate along with the rotating member 321, one end of the rotating member 321, which is close to the gear set 312, is provided with a flat position, the potentiometer is arranged at a position opposite to the flat position, and the flat position of the rotating member 321 is inserted into a flat position hole of the potentiometer. The flat position and the flat position hole are matched, so that the potentiometer can detect the rotation angle of the rotating piece 321. The potentiometer may be electrically connected to the motherboard of the electronic device 100, and transmit the detected data back to the motherboard of the electronic device 100, where the motherboard may calculate the moving distance of the moving member 322 according to the stored data and the rotating angle of the rotating member 321.

In addition, in the embodiment of the present application, the type of the position detecting device 60 is not limited, and the position detecting device 60 may be a sensor such as a photoelectric counter or a hall sensor, so as to meet various requirements.

Referring to fig. 5 and 10, in some embodiments, the electronic device 100 further includes a tensioning structure 70, the tensioning structure 70 being mounted within the first housing 11 and connecting an end of the extension portion 22 remote from the flat portion 21, the tensioning structure 70 being used to tension the flexible display screen 20.

In this manner, the tensioning structure 70 is capable of tensioning the flexible display 20 assembly during deployment of the extension 22 out of the housing assembly 10 or retraction into the housing assembly 10 by the second housing 12, such that the extension 22 does not buckle or pucker to ensure that the extension 22 can be deployed or retracted smoothly.

Further, referring to fig. 5 and 10, in some embodiments, the tensioning structure 70 includes a pull cord 71 and a tensioning member 72, the tensioning member 72 being disposed on the second shell 12 and capable of following movement of the second shell 12 relative to the first shell 11, one end of the pull cord 71 being fixedly connected to the expansion portion 22, the other end being fixedly connected to the first shell 11, and the stretched intermediate portion being wound around the tensioning member 72.

In this way, the pull cord 71 may tighten the flexible display 20 when the flexible display 20 is retracted, avoiding wrinkling of the flexible display 20, and the tensioning member 72 may guide the auxiliary pull cord 71 to move.

Specifically, when the second housing 12 is relatively far from the first housing 11, the tension member 72 follows the movement of the second housing 12, and one end of the pull cord 71 is fixedly connected to the expansion portion 22, and the other end is fixedly connected to the first housing 11. In addition, the electronic device 100 may further include a guide shaft 80, the guide shaft 80 being used to guide the movement of the flexible display 20, and the middle portion of the extension portion 22 may be partially bent around the guide shaft 80, so that the guide shaft 80 may be engaged with the tension structure 70, and the guide shaft 80 may guide the extension portion 22 to enable the extension portion 22 to be smoothly extended or retracted when the extension portion 22 moves.

In some embodiments, the electronic device 100 further includes a bracket 51 fixedly connected to the expansion portion 22, and one end of the pull cord 71 is fixedly connected to the bracket 51 to achieve a fixed connection to the expansion portion 22. The bracket 51 may have an elongated rectangular structure, and the bracket 51 may connect the connection frame 50 and one end of the expansion portion 22. The bracket 51 may be disposed along the length of the electronic device 100 to increase the contact area between the bracket 51 and the extension 22, and further stabilize the transmission process of the transmission assembly 32.

In one example, during the process of separating the second shell 12 from the first shell 11, the tensioning member 72 gradually releases the pull rope 71, so as to gradually release the extension portion 22, and the extension portion 22 is gradually unfolded outside the housing assembly 10 under the action of the second shell 12, so that the distance of movement of the tensioning member 72 is the same as the movement travel of the extension portion 22, and during the process of gradually unfolding the extension portion 22 outside the housing assembly 10, the tensioning member 72 can tension the pull rope 71, so as to realize tensioning of the flexible display screen 20.

In another example, during the process that the second shell 12 is relatively close to the first shell 11, the tensioning member 72 moves along with the second shell 12, one end of the pull rope 71 is fixedly connected with the expansion part 22, the other end of the pull rope 71 is fixedly connected with the first shell 11, the second shell 12 gradually releases the expansion part 22, the tensioning member 72 drives the pull rope 71 to move towards the side where the first shell 11 is located, and accordingly the expansion part 22 is driven to be gradually retracted into the shell assembly 10, in such a process, the moving distance of the tensioning member 72 and the moving stroke of the expansion part 22 are the same, and in this way, the tensioning member 72 can tension the pull rope 71 during the process that the expansion part 22 is retracted and expanded into the shell assembly 10, and thus the tensioning of the flexible display screen 20 is achieved. It will be appreciated that during the assembly process of the electronic device 100, one end of the pull cord 71 may be fixedly connected to the first housing 11 after the tensioning member 72 and the pull cord 71 are sequentially wound, and during the installation process, it is required to ensure that the flexible display 20 is in a tensioned state, so that the tensioning structure 70 can tension the flexible display 20 regardless of the movement of the second housing 12 due to the tensioning structure 70.

Further, referring to fig. 10, in some embodiments, the tensioning member 72 includes a pulley 721, the pulley 721 is rotatably disposed on the second housing 12, the middle portion of the pull cord 71 is wound around the pulley 721, and the rotation axis of the pulley 721 is perpendicular to the flat portion 21.

Thus, the pulley 721 and the guide shaft 80 are provided on the second housing 12, and both constitute a pulley 721 assembly, thereby enabling the flexible display 20 to be smoothly extended and retracted.

Specifically, in the embodiment of the present application, the pulley 721 may be rotatably provided on the second housing 12 by a bolt thread, and the intermediate portion of the pull cord 71 is wound around the pulley 721. Thus, when the second shell 12 moves the extension portion 22 and the pull rope 71, the pulley 721 rolls correspondingly, rolling friction is generated between the extension portion 22 and the pull rope 71, and the friction force is small, so that compared with the mode of directly fixing the tensioning piece 72 on the second shell 12, the rotation can prevent the pull rope 71 from being worn more and even clamping the pull rope 71 due to overlarge friction force between the pull rope 71 and the tensioning piece 72.

Of course, it should be understood that in some embodiments, the tensioning member 72 may be directly fixed to the first housing 11, so long as the surface of the tensioning member 72 is smooth enough to avoid a large friction force with the pull cord 71 during the manufacturing process.

Furthermore, it will be appreciated that in some embodiments, the tensioning structure 70 may also be a spool rotatably mounted on the first housing 11, one end of the extension 22 being windable on the spool, the spool being capable of winding or releasing the extension 22, such that the flexible display 20 may also be tensioned by the spool.

In addition, referring to fig. 1 to 3, in the electronic device 100 of some embodiments, the electronic device 100 may include a housing assembly 10, a flexible display 20, and a driving module 30, wherein the housing assembly 10 includes a first housing 11 and a second housing 12 that are slidably connected; one end of the flexible display screen 20 is connected with the first shell 11, the other end of the flexible display screen is arranged in the shell assembly 10, and the second shell 12 can slide relative to the first shell 11 so that the part of the flexible display screen 20 positioned in the shell assembly 10 can be at least partially unfolded outside the shell assembly 10; the driving module 30 is installed in the first shell 11, the driving module 30 comprises a driving device 31 and a transmission assembly 32, the transmission assembly 32 is connected with the driving device 31, the driving device 31 comprises a motor 311, the transmission assembly 32 comprises a rotating piece 321 and a moving piece 322, the rotating piece 321 is rotatably arranged on the first shell 11 and is connected with the motor 311, the motor 311 is arranged on one side of the rotating piece 321, a motor shaft of the motor 311 is perpendicular to a rotation axis of the rotating piece 321, the moving piece 322 is in threaded connection with the rotating piece 321, the second shell 12 is fixedly connected, and the motor 311 is used for driving the rotating piece 321 to rotate so as to drive the moving piece 322 to move along the axial direction of the rotating piece 321 on the rotating piece 321, so that the second shell 12 is driven to slide relative to the first shell 11.

In such an embodiment, the motor 311 of the driving module 30 is disposed at one side of the rotating member 321, and the motor shaft of the motor 311 is disposed perpendicular to the rotating member 321 (i.e., the motor 311 is perpendicular to the rotating member 321) so that the overall arrangement of the driving module 30 is substantially L-shaped. In this way, the overall layout of the driving module 30 is optimized, so that the structure of the driving module 30 is more compact, and meanwhile, the motor 311 is arranged perpendicular to the rotating member 321, so that the situation that the thickness of the electronic device 100 is increased due to the overlapping part between the expansion part 33 and the motor 311 caused by the longer length of the motor 311 when the motor 311 and the rotating member 321 are arranged in parallel can be effectively avoided, and the electronic device 100 is light and thin.
