Referring to fig. 1 to 4, an electronic device 100 is provided in an embodiment of the present disclosure, where 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 housing 11 and a second housing 12 slidably coupled. The flexible display 20 includes a flat portion 21 exposed from the housing assembly 10 and an extension portion 22 connected to the flat portion 21, the flat portion 21 is fixedly connected to the first housing 11, the extension portion 22 can be hidden in the housing assembly 10, and the second housing 12 can slide relative to the first housing 11 to at least partially extend the extension portion 22 out of the housing assembly 10 or retract the extension portion 22 into the housing assembly 10. The driving module 30 is installed in the first housing 11, the driving module 30 includes a driving device 31 and a transmission assembly 32, the transmission assembly 32 is connected to the driving device 31, the transmission assembly 32 is connected to the second housing 12, the driving device 31 is configured to drive the second housing 12 to slide relative to the first housing 11 through the transmission assembly 32, and an orthographic projection of the driving device 31 on the flat portion 21 and an orthographic projection of the extension portion 22 on the flat portion 21 are mutually misaligned.

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 extended or retracted into the housing assembly 10 to adjust the display area of the electronic device, and the orthographic projection of the driving device 31 on the flat portion 21 and the orthographic projection of the extension portion 22 on the flat portion 21 are mutually misaligned. Thus, the driving device 31 and the flat portion 21 can be installed in the housing assembly 10 in a staggered manner, and the driving device 31 is installed outside the overlapping region 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 and the like) in the electronic device 100 can avoid the extension portion hidden in the housing assembly 10, thereby effectively reducing the stacking thickness, enabling the electronic device 100 to be thinner and lighter, and improving the user experience.

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

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

In the embodiment of the present application, the fact that the extension portion 22 can be hidden in the housing assembly 10 means that the extension portion 22 can be housed in the internal space of the housing assembly 10 and is not exposed, or the fact that the extension portion 22 can be hidden on the back surface of the housing assembly 10 and is exposed from the back surface is described herein by way of example, the extension portion 22 can be housed in the internal space of the housing assembly 10 and is not exposed.

It is understood that the driving device 31 is installed in the first housing 11 to drive the second housing 12 to move relative to the first housing 11, and the flexible display 20 is moved when the second housing 12 moves relative to the first housing 11, so that the electronic device 100 can be switched between two configurations. In some embodiments, the first casing 11 of the electronic device 100 may serve as a main supporting structure of the electronic device 100, and the driving module 30, the speaker, the circuit board, the battery, and other components may be accommodated inside the first casing 11. Additionally, 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 collapsed inside the first shell 11. In some embodiments, the first housing 11 and the second housing 12 may have similar shapes, and the second housing 12 and the first housing 11 cooperate to form a complete support structure, which makes the flexible display 20 symmetrical and beautiful when unfolded.

Specifically, in the illustrated embodiment, the first housing 11 is slidably connected to the second housing 12, and the extension portion 22 of the flexible display 20 can be disposed inside the housing assembly 10, belonging to a hidden structure. Referring to fig. 3, in the first configuration, the extended portion 22 of the flexible display screen 20 is not used for display, and only the flat portion 21 is used for display. When the second housing 12 moves away from the first housing 11, the flexible display 20 can be moved, so that the extension portion 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 portion 22 is at least partially pulled out of the housing assembly 10, and the flat portion 21 and the extension portion 22 are simultaneously used for displaying, thereby changing the display area of the electronic device 100. During the switching of the two forms, the driving device 31 is used for providing a driving force, and the transmission assembly 32 is used for transmitting the driving force to the housing assembly 10, so that the second shell 12 moves relative to the first shell 11, and the expansion part 22 is at least partially expanded out of the housing assembly 10 or retracted into the housing assembly 10.

In the embodiment of the present application, the flat portion 21 and the extended portion 22 of the flexible display 20 are disposed in a U shape, and the orthographic projection of the driving device 31 on the flat portion 21 and the orthographic projection of the extended 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 disposed between the overlapped portions of the flat portion 21 and the extended portion 22 is avoided, and the electronic device 100 can be made thinner. It is understood 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 more delicate. In some embodiments, the saved space can be used to increase the accommodation of the battery, so that the electronic device 100 can be used for a longer time, and the user experience can be improved.

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

The electronic device 100 in the 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 vehicle-mounted computer, a notebook computer, or a video player, and is not specifically shown here.

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

It should be noted that in the description of the present application, it is to be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner" and "outer" indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present application. In addition, it should be noted that, in the description of the present application, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be interpreted broadly, e.g., as either a fixed connection, a detachable connection, or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

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

Therefore, the thickness increase of the electronic device 100 caused by the motor 311 being disposed between the flexible display screens 20 is avoided, 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 to 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 orthographic projection of the gear set 312 on the flat portion 21 and the orthographic projection of the expanded portion 22 on the flat portion 21 are mutually offset; or the orthographic projection of the gear set 312 on the flat portion 21 at least partially overlaps the orthographic projection of the expanded portion 22 on the 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 distribution of the electromechanical device 100, and make the electronic device 100 lighter and thinner.

Specifically, in some embodiments, the motor 311 may be maintained only at a position where the orthographic projection of the motor 311 on the flat portion 21 and the orthographic projection of the extension portion 22 on the flat portion 21 are offset from each other, and in this case, the specific position of the gear set 312 is not limited, and it is only necessary to ensure that the gear set 312 is disposed in the first housing 11 to connect the motor 311 and the transmission assembly 32.

In some embodiments, it is possible to keep only the gear set 312 in a position in which its orthographic projection on the flat portion 21 is offset from the orthographic projection of the expanded portion 22 on the flat portion 21; or the orthographic projection of the gear group 312 on the flat portion 21 and the orthographic projection of the expanded portion 22 on the flat portion 21 at least partially overlap, in this case, it is not necessary to define the specific position of the motor 311, but it is only necessary to ensure that the motor 311 is disposed in the first housing 11 so that the motor 311 can provide the driving force.

In some embodiments, it is ensured that the motor 311 is arranged in a position in which the orthographic projection of the motor on the flat portion 21 is offset from the orthographic projection of the extension portion 22 on the flat portion 21. While maintaining the gear set 312 in a position where its orthographic projection on the flat portion 21 is offset from the orthographic projection of the expanded portion 22 on the flat portion 21; or the orthographic projection of the gear set 312 on the flat portion 21 at least partially overlaps the orthographic projection of the expanded portion 22 on the 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 threadedly connected to the rotating member 321, and the second housing 12 is fixedly connected. 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 to drive the second shell 12 to slide relative to the first shell 11.

In this way, when the rotating element rotates, the moving element 322 may move along the axial direction of the rotating element 321 to drive the second shell 12 to slide relative to the first shell 11, so that the expanding portion 22 at least partially extends out of the housing assembly 10 or retracts into the housing assembly 10, and the electronic device 100 may be switched between the first configuration and the second configuration.

Specifically, in one possible embodiment, the rotating member 321 may be a lead screw, and the moving member 322 may be a nut, thereby forming a lead screw nut transmission structure. The motor 311 provides a driving force and transmits the driving force to the gear set 312, and the gear set 312 can adjust the rotation speed to a proper value and then transmit the rotation speed to the rotating member 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. And the flat portion 21 is connected to the first shell 11, so that the expanded portion 22 can be at least partially expanded 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 part 321 as the lead screw as an example, the rotating part 321 may include a threaded section, and the moving part 322 is sleeved on the threaded section and is in threaded connection with the threaded section, so that when the rotating part 321 rotates one turn along the first direction, the moving part 322 moves on the rotating part 321 by a distance of one thread pitch, so that the second shell 12 slides by a distance of one thread pitch to a side away from the first shell 11, and then the distance that the extension part 22 is extended to the shell 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 on the rotating member 321 by one pitch in the opposite direction, so that the second shell 12 slides to a side close to the first shell 11 by one pitch, and then the distance for the extension portion 22 to retract into the housing assembly 10 is obtained, 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 perpendicular to a rotation axis of the rotation member 321, the gear set 312 includes a reversing gear set 313 and a transmission gear set 314, the reversing gear set 313 is connected to the motor shaft of the motor 311 and meshed with the transmission gear set 314, the transmission gear set 314 is connected to the rotation member 321, and the reversing gear set 313 and the transmission gear set 314 can convert the rotation of the motor shaft of the motor 311 into the rotation of the rotation member 321.

Thus, the motor shaft of the motor 311 is perpendicular to the rotation axis of the rotating member 321, 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 is optimized.

Specifically, the driving device 31 and the transmission assembly 32 may be distributed in an L shape, a motor shaft of the motor 311 may be disposed at an end of the first housing 11 away from the second housing 12 along a length direction of the electronic device 100, and the rotating member 321 may be rotatably disposed at 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 can change the rotation direction of the gear when transmitting the rotation of the motor shaft to the transmission gear set 314, so that the transmission gear set 314 can be connected with the rotating member 321 to rotate the rotating member 321. The transmission gear set 314 can change the gear rotation speed so that the rotation member 321 rotates at an 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 parallel to the rotating member 321, the reversing gear 3133 is mounted on the reversing shaft 3132 and is engaged with the first transmission gear 3131, and the second transmission gear 3134 is mounted on the reversing shaft 3132 and is engaged with the transmission gear set 314.

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

Specifically, a first transmission gear 3131 may be mounted on the motor shaft to rotate together with the motor shaft, the first transmission gear 3131 is meshed with a direction-changing gear 3133 already mounted on a direction-changing shaft 3132, so that the motor shaft may drive the direction-changing gear 3133 to rotate through the first transmission gear 3131, and the direction-changing gear 3133 is mounted on the direction-changing shaft 3132 to drive the direction-changing shaft 3132 to rotate. The direction change shaft 3132 is disposed parallel to the rotation member 321 such that the axis of the direction change shaft 3132 is perpendicular to the motor shaft of the motor 311. The direction changing shaft 3132 is mounted with a second driving gear 3134, the second driving gear 3134 is rotatable with the direction changing shaft 3132, the second driving gear 3134 is engaged with the driving gear set 314 to transmit a driving force to the driving gear set 314, the driving gear set 314 is connected to the rotation member 321, and the driving gear set 314 can change a gear rotation speed such that the rotation member 321 rotates at a proper speed. Specifically, in the embodiment of the present application, the reverse 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 are rotating in 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 arranged in parallel along the sliding direction of the second housing 12, a motor shaft of the first motor 3111 and a motor shaft of the second motor 3112 are both perpendicular to the rotation axis of the rotating member 321, the number of the first transmission gears 3131 is two, the 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, the number of the reversing gears 3133 is also two, and each reversing gear 3133 corresponds to one first transmission gear 3131.

Thus, the first motor 3111 and the second motor 3112 can provide driving force simultaneously to ensure the rotation member 321 to rotate smoothly, so as to make the electronic device 100 switch smoothly between the first mode and the second mode, and avoid the situation that the opening and closing speed is slow, or even the opening and closing cannot be performed normally, caused by insufficient driving force when the second housing 12 moves relative to the first housing 11.

Specifically, a driving force is generated by the motor 311, or the motor 311 rotates a motor shaft under the action of the electric force, and the motor shaft is connected with the gear set 312 and drives the gear set 312 to rotate. It is understood that when a single motor 311 cannot provide sufficient driving force, two motors 311, i.e., the first motor 3111 and the second motor 3112, may be used to provide driving force simultaneously. The first motor 3111 and the second motor 3112 may use the same kind and model of the motor 311, for example, the first motor 3111 and the second motor 3112 may be two stepping motors 311 placed side by side, a motor shaft of the first motor 3111 and a motor shaft of the second motor 3112 are both perpendicular to a rotation axis of the rotation member 321, and protruding lengths of the two motor shafts are identical, and two first transmission gears 3131 are respectively provided at the same position of the two motor shafts. The first motor 3111 and the second motor 3112 may be simultaneously started and stopped, and drive force is externally output with 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 a motor shaft of the first motor 3111 and a motor shaft of the second motor 3112, and there are two reverse gears 3133 that are engaged with the first transmission gears 3131, and each reverse gear 3133 corresponds to one first transmission gear 3131. Two reversing gears 3133 are mounted on the same reversing shaft 3132, so that two motors 311 can provide driving force to drive the reversing shaft 3132 to rotate at the same time, i.e. the reversing shaft 3132 also has two first transmission gears 3131 cooperating to combine the driving force provided by the two motors 311 into one. The reversing shaft 3132 is further provided with a second driving gear 3134, the second driving gear 3134 is engaged with the driving gear set 314 and transmits the driving force to the driving gear set 314, and the driving gear set 314 converts the rotation speed into a suitable value and transmits the same to the rotating member 321. The rotating component 321 rotates to enable the moving component 322 to move on the rotating component 321, and the moving component 322 is connected to the second shell 12 to drive the second shell 12 to move, so that the expansion portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10, so as to adjust the display area of the electronic device 100.

It can be understood that, a transmission assembly 32 is connected simultaneously to first motor 3111 and second motor 3112, provides drive power for transmission assembly 32, compares two motors 31 and corresponds two transmission assemblies 32, further optimizes the space for the space of saving can be used for the holding of increase battery etc. improves 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.

Thus, the guide 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 second housing 12 moving relative to the first housing 11 and avoiding possible jamming.

Specifically, the guide shaft 40 is disposed in the first housing 11 in parallel with the rotation member 321, and the guide shaft 40 may be disposed at a position closer to the rotation member 321, so that the moving member 322 may be simultaneously inserted through the guide shaft 40 and the rotation member 321. Thus, when the rotating member 321 rotates, the moving member 322 will not follow the rotating member 321 to rotate, but will move along the axial direction of the rotating member 321 through the threaded section.

In addition, in some embodiments, the electronic device 100 further includes a connecting frame 50, and the connecting frame 50 is fixedly connected to the second housing 12 and can move together with the second housing 12. The moving member 322 may include a protrusion, the connecting frame 50 may include a groove, and the moving member 322 and the connecting frame 50 may move together through the engagement of the protrusion and the groove, or the moving member 322 may move the connecting frame 50 to move the second shell 12 relative to the first shell 11. The connecting frame 50 serves as a place for receiving the acting force, so that the contact area with the second housing 12 can be increased, and thus, 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 is transmitted to the rotating member 321 through the reversing gear set 313 and the transmission gear set 314, the rotating member 321 rotates to enable the moving member 322 to move axially along the rotating member 321, the moving member 322 is connected to the second shell 12 through the connecting frame 50, and further enables the second shell 12 to move relative to the first shell 11, so that the second shell 12 drives the expansion portion 22 to extend out of the housing assembly 10 or retract into the housing assembly 10.

Further, in some embodiments, the connecting frame 50 and the rotating member 321 are located at the middle position of the housing assembly 10, so that stable transmission can be achieved only by matching one group of connecting frames 50 with the transmission assembly 32, and the phenomena of skewing, jamming and the like caused by the fact that the second shell moves relative to the first shell due to the fact that one group of connecting frames 50 and the transmission assembly 32 are arranged at other positions are 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, 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, so as to detect a relative position of the second housing 12 and the first housing 11.

For example, the position detecting device 60 may be a potentiometer, and the potentiometer may be used to detect a rotation angle of the rotating member 321, so as to obtain a moving stroke of the moving member 322 according to the rotation direction and the rotation angle. The potentiometer is at least partially disposed on the rotating member 321 for rotation with the rotating member 321, the rotating member 321 has a flat portion at an end thereof adjacent to the gear set 312, the potentiometer is disposed at a position opposite to the flat portion, and the flat portion of the rotating member 321 is inserted into the flat portion hole of the potentiometer. The flat and flat hole cooperate to allow the potentiometer to detect the rotation angle of the rotating member 321. The potentiometer can be electrically connected to the main board of the electronic device 100, and the detected data can be transmitted back to the main board of the electronic device 100, and the main board can calculate the moving distance of the moving member 322 according to the stored data of the rotating member 321 and the rotating angle.

In addition, in the embodiment of the present application, the type of the position detection device 60 is not limited, and the position detection device 60 may also 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 is installed in the first housing 11 and connected to an end of the extension portion 22 away from the flat portion 21, and the tensioning structure 70 is used for tensioning the flexible display screen 20.

Thus, the tensioning structure 70 can tension the assembly of the flexible display screen 20 during the process of the second shell 12 carrying the expansion portion 22 to be expanded out of the housing assembly 10 or to be retracted into the housing assembly 10, so that the expansion portion 22 is not arched or folded to ensure that the expansion portion 22 can be smoothly expanded or retracted.

Further, referring to fig. 5 and 10, in some embodiments, the tension structure 70 includes a tension rope 71 and a tension member 72, the tension member 72 is disposed on the second shell 12 and can move along with the second shell 12 relative to the first shell 11, one end of the tension rope 71 is fixedly connected to the expansion portion 22, the other end is fixedly connected to the first shell 11, and the stretched middle portion is wound on the tension member 72.

In this way, the pulling rope 71 can pull the flexible display 20 tightly when the flexible display 20 is retracted, so as to prevent the flexible display 20 from being folded, and the tensioning member 72 can guide the auxiliary pulling rope 71 to move.

Specifically, when the second shell 12 is relatively away from the first shell 11, the tension member 72 follows the movement of the second shell 12, and one end of the pulling rope 71 is fixedly connected to the expansion portion 22 and the other end is fixedly connected to the first shell 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 a middle portion of the extension portion 22 may be partially bent around the guide shaft 80, so that the guide shaft 80 may cooperate 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 rope 71 is fixedly connected to the bracket 51 to achieve the fixed connection with the expansion portion 22. The bracket 51 may have an elongated rectangular structure, and the bracket 51 may connect the connecting bracket 50 and one end of the expansion part 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 portion 22, so as to further stabilize the driving process of the driving assembly 32.

In one example, the tension member 72 gradually releases the pulling rope 71 during the process of moving the second shell 12 away from the first shell 11, so as to gradually release the expansion portion 22, the expansion portion 22 is gradually expanded out of the housing assembly 10 under the action of the second shell 12, and the movement distance of the tension member 72 is the same as the movement stroke of the expansion portion 22, so that the tension member 72 can tension the pulling rope 71 during the process of gradually expanding the expansion portion 22 out of the housing assembly 10, so as to realize the tension on 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 pulling rope 71 is fixedly connected to the expansion portion 22, the other end of the pulling rope 71 is fixedly connected to the first shell 11, the second shell 12 gradually releases the expansion portion 22, the tensioning member 72 drives the pulling rope 71 to move toward the side where the first shell 11 is located, so as to drive the expansion portion 22 to gradually retract into the housing assembly 10, in such a process, the moving distance of the tensioning member 72 and the moving stroke of the expansion portion 22 are the same, so that during the process that the expansion portion 22 retracts into the housing assembly 10, the tensioning member 72 can both tension the pulling rope 71, thereby achieving the tensioning of the flexible display screen 20. It can be understood that, during the assembly process of the electronic device 100, one end of the pulling rope 71 can be sequentially wound around the tensioning member 72 and the pulling rope 71 and then fixedly connected to the first shell 11, and during the installation process, it is required to ensure that the flexible display screen 20 is in a tensioned state, so that due to the existence of the tensioning structure 70, the tensioning structure 70 can tension the flexible display screen 20 no matter how the second shell 12 moves.

Further, referring to fig. 10, in some embodiments, the tension member 72 includes a pulley 721, the pulley 721 is rotatably disposed on the second housing 12, the intermediate portion of the rope 71 is wound around the pulley 721, and the rotational axis of the pulley 721 is perpendicular to the flat portion 21.

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

Specifically, in the embodiment of the present application, the pulley 721 may be screw-rotatably provided on the second case 12 by a bolt, and the intermediate portion of the rope 71 is wound around the pulley 721. Thus, when the second shell 12 drives the expansion part 22 and the pulling rope 71 to move, the pulley 721 rolls correspondingly, rolling friction exists between the two, friction force is small, and compared with a mode of directly fixing the tensioning member 72 on the second shell 12, rotation can prevent the pulling rope 71 from being abraded greatly or even clamping the pulling rope 71 due to overlarge friction force between the pulling rope 71 and the tensioning member 72.

Of course, it is understood that in some embodiments, the tension member 72 may be directly fixed to the first shell 11, and it is only necessary to make the surface of the tension member 72 smooth and not generate a large friction force with the pulling rope 71 during the manufacturing process.

Furthermore, it is understood that in some embodiments, the tensioning structure 70 may also be a reel rotatably disposed on the first housing 11, one end of the extension portion 22 may be wound on the reel, and the reel may wind or release the extension portion 22, so that the flexible display screen 20 may be tensioned by the reel as well.

In addition, referring to fig. 1 to fig. 3, to sum up, 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 slidably connected to each other; one end of the flexible display screen 20 is connected with the first shell 11, the other end 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, which is positioned in the shell assembly 10, is at least partially unfolded out of the shell assembly 10; the driving module 30 is installed in the first shell 11, the driving module 30 includes a driving device 31 and a transmission assembly 32, the transmission assembly 32 is connected to the driving device 31, the driving device 31 includes a motor 311, the transmission assembly 32 includes a rotation member 321 and a moving member 322, the rotation member 321 is rotatably disposed on the first shell 11 and connected to the motor 311, the motor 311 is disposed on one side of the rotation member 321 and a motor shaft of the motor 311 is perpendicular to a rotation axis of the rotation member 321, the moving member 322 is in threaded connection with the rotation member 321 and is fixedly connected to the second shell 12, the motor 311 is configured to drive the rotation member 321 to rotate so as to drive the moving member 322 to move on the rotation member 321 along an axial direction of the rotation member 321, and thus drive the second shell 12 to slide relative.

In such an embodiment, the motor 311 of the driving module 30 is disposed on 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.
