In this way, the photoelectric detection assembly 40 is used to detect the movement stroke between the first shell 11 and the second shell 12 of the housing, so that the current of the electronic elements such as the main board in the electronic device 100 and the interference of other magnets to the detection can be avoided, and the detection precision and reliability are improved.

Referring to fig. 1 and fig. 2, an electronic device 100 according to an embodiment of the present disclosure may include two modes. The first configuration is a configuration in which the first housing 11 and the second housing 12 are fitted together (see fig. 1), that is, the configuration in which 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 screen 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 is 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 extension portion 22 of the flexible display screen 20 to gradually extend out of the housing assembly 10 (see fig. 2), and in the second configuration, the extension portion 22 of the flexible display screen 20 at least partially extends 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.

Herein, the "display area" refers to an area of a portion of the flexible display 20 exposed outside the housing assembly 10 for displaying, so that the sliding direction and the sliding distance of the second housing 12, i.e., an area of the extended portion 22 exposed from the housing assembly 10, can be obtained only by detecting the rotating direction of the rotating angle of the rotating member 31, and thus, the display area of the electronic device 100 can be obtained only by adding the area of the extended portion 22 exposed to the area of the flat portion 21.

The electronic device 100 in the embodiment of the present application may include, but is not limited to, a mobile terminal device such as a smart phone, a tablet computer, and the like.

In some embodiments, the first housing 11 may be substantially rectangular, the first housing 11 may also serve as a main body supporting structure of the electronic device 100, a mounting cavity (not shown) may be formed inside the first housing 11, the mounting cavity may be used to partially receive the second housing 12 and components such as a speaker, a main board, and a battery for placing the electronic device 100, and the photoelectric counter 41 is disposed on the main board and electrically connected to the main board. The second housing 12 may also be substantially rectangular in shape, the second housing 12 being slidably connected to the first housing 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 partially 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 extension 22 of the flexible display 20 may be disposed inside the housing assembly 10 in a recessed configuration. In the first configuration, the extended portion 22 of the flexible display 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 modes, the driving assembly 30 drives the second shell 12 to move relative to the first shell 11 through the rotation of the rotating member 31, so that the expanding portion 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10.

It is noted that in the description of the present application, such as the "first shell" and the "second shell" described above, the terms "first" and "second" are used for descriptive purposes only and do not indicate that the housing assembly 10 has only two shells, nor does it imply that the first shell 11 is more important than the second shell 12, or that the terms "first" and "second" are not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In addition, in the description of the present application, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable 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.

Specifically, in the embodiment of the present application, the rotating element 31 may be a lead screw, and the rotating element 31 may be directly screwed with the second housing 12, or a nut is sleeved on the rotating element 31 and then fixedly connected with the second housing 12. Thus, the moving distance of the second housing 12 can be obtained only by measuring the rotation angle of the rotation member 31.

The photoelectric counter 41 and the code disc 42 of the photoelectric detection assembly 40 can be used for detecting the rotation angle of the rotation member 31, so as to detect the sliding distance of the second shell 12, thereby realizing accurate detection and adjustment of the display area of the electronic device 100. The photoelectric counter 41 is an automatic counting device made of photoelectric elements, the photoelectric counter 41 is fixedly connected with the first shell 11, and the code disc 42 rotates to change the times of the collected optical signals of the photoelectric counter 41, so that a processor on a main board of the electronic device 100 can calculate the rotation angle of the rotating member 31 according to the times of the collected optical signals of the photoelectric counter 41, and further obtain the movement stroke between the first shell 11 and the second shell 12.

Further, referring to fig. 4 and 5, in such an embodiment, the photoelectric counter 41 includes a light emitting tube 411 and a receiving tube 412, the receiving tube 412 is spaced from the light emitting tube 411, and the code wheel 42 is located between the light emitting tube 411 and the receiving tube 412. The code wheel 42 is provided with a plurality of through grooves 4221 at intervals along the rotating direction, the through grooves 4221 penetrate through the code wheel 42, and when the through grooves 4221 are opposite to the receiving pipe 412 and the light emitting pipe 411, the receiving pipe 412 can receive light rays emitted by the light emitting pipe 411.

In this way, the coded disc 42 blocks the light between the light emitting tube 411 and the receiving tube 412 during the rotation process, and the coded disc 42 is provided with a plurality of through grooves 4221 at intervals along the rotation direction to allow the light to pass through, so that the photoelectric counter 41 can calculate the rotation angle of the coded disc 42 by the number of times of the light received by the receiving tube 412, further obtain the rotation angle of the rotating member 31, and calculate the moving stroke of the second shell 12 relative to the first shell 11.

Specifically, the code wheel 42 may include a coupling portion 421 and a disk portion 422, the coupling portion 421 being disposed at the center of the disk portion 422 and coaxially with the disk portion 422, the coupling portion 421 coupling the rotating member 31 so that the code wheel 42 can perform a rotational movement together with the rotating member 31.

The plurality of through grooves 4221 of the code wheel 42 are provided at equal intervals on the disk portion 422, and the through grooves 4221 penetrate the disk portion 422 of the code wheel 42, that is, the through grooves 4221 and the barrier portions 4222 provided at intervals in the circumferential direction of the code wheel 42 are formed. When the connecting portion 421 of the code wheel 42 is connected to the rotary member 31, the disc portion 422 of the code wheel 42 is located between the light emitting tube 411 and the receiving tube 412, so that the blocking portion 4222 can block the light path from the light emitting tube 411 to the receiving tube 412, and the through groove 4221 can pass the light emitted from the light emitting tube 411 to the receiving tube 412. Thus, the optical signal received by the receiving tube 412 may be intermittent when the code wheel 42 follows the rotation of the rotation member 31, and the photoelectric counter 41 may record the number of times the optical signal is received, thereby obtaining the rotation angle of the rotation member 31, and the angle of the rotation member 31 may correspond to the moving distance of the second housing 12 relative to the first housing 11. Thereby, the sliding distance of the second housing 12 with respect to the first housing 11 can be accurately detected.

Referring to fig. 3 and 4, in some embodiments, the driving assembly 30 further includes a moving member 32 sleeved on the rotating member 31, the moving member 32 is connected to the rotating member 31 through a screw thread, and the second shell 12 is fixedly connected to the rotating member 31, when the rotating member 31 rotates, the rotating member 31 can drive the moving member 32 to move on the rotating member 31 along an axial direction of the rotating member 31 to drive the second shell 12 to slide relative to the first shell 11.

Thus, the moving member 32 is in threaded connection with the rotating member 31 and the second shell 12 is fixedly connected, when the rotating member rotates, the moving member 32 can move along the axial direction of the rotating member 31 to drive the second shell 12 to slide relative to the first shell 11, and the sliding distance of the second shell 12 can be obtained only by detecting the rotating angle of the rotating member 31 through the photoelectric detection component 40.

Specifically, the rotating member 31 may be a lead screw, and the moving member 32 may be a nut, thereby forming a lead screw nut transmission structure. Thus, when the rotating member 31 rotates, the rotating member 31 can drive the moving member 32 to move on the rotating member 31, thereby moving the second housing 12 relative to the first housing 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.

It is understood that in other embodiments, the rotating member 31 may also be a worm, in such embodiments, the driving assembly 30 may further include a worm wheel, the second housing 12 may be provided with a rack portion, the worm wheel is engaged with the worm wheel, the worm wheel is directly engaged with the rack portion of the second housing 12 or engaged with the rack portion of the second housing 12 through a gear, so that the worm is driven by the driving assembly 30 to rotate, and the second housing 12 can be driven to slide relative to the first housing 11, and thus, the sliding distance of the second housing 12 can be obtained by only measuring the rotating angle of the rotating member 31.

Furthermore, it is also understood that, in some embodiments, the electronic device 100 may not include the moving member 32 but directly screw the second housing 12 and the rotating member 31. For example, a threaded hole is formed in the second housing 12, and the rotating member 31 is threaded through the threaded hole to be in threaded connection with the second housing 12, so that when the rotating member 31 rotates, the second housing 12 can be directly driven to slide relative to the first housing 11 along the axial direction of the rotating member 31, that is, the axial direction of the rotating member 31 is parallel to the sliding direction of the second housing 12, and the invention is not limited thereto.

Referring to fig. 3 and 4, in some embodiments, the code wheel 42 is disposed coaxially with the rotary member 31.

In this way, the code wheel 42 and the rotating member 31 rotate coaxially, thereby avoiding possible delay or error between the code wheel 42 and the rotating member 31 and improving the detection accuracy of the photoelectric detection assembly 40.

Specifically, the code wheel 42 is provided coaxially with the rotary member 31, or the code wheel 42 may be directly mounted on one end of the rotary member 31, and rotates coaxially with the rotary member 31 at the code wheel 42. The code wheel 42 and the rotary member 31 are coupled together to prevent a delay or error in making a rotary motion. It is understood that in the present embodiment, the coaxial arrangement means that the axes of the code wheel 42 and the rotating member 31 are completely coincident or the eccentricity between the axes is within the assembling error range. The accuracy of the photodetection assembly 40 is ensured.

Further, referring to fig. 4 and 5, in some embodiments, the code wheel 42 is formed with a threaded hole 4211, one end of the rotating member 31 is formed with threads, and the code wheel 42 is threadedly coupled with the rotating member 31 through the threaded hole 4211.

In this manner, the code wheel 42 and the rotation member 31 are screwed together through the threaded hole 4211 so that the code wheel 42 and the rotation member 31 can rotate coaxially.

Specifically, the rotating member 31 may have a cylindrical shape, and one end of the rotating member 31 may be formed with a screw thread, or one end of the rotating member 31 may be formed with a screw post. The coupling portion 421 of the code wheel 42 protrudes from the middle of the disc portion 422 and is formed with a screw hole 4211 to couple with the rotation member 31. The connecting portion 421 is connected to the threaded post through a threaded hole 4211 so that the code wheel 42 can rotate together with the rotating member 31, and the disk portion 422 is used for cooperating with the photoelectric counter 41 to record the rotating angle of the code wheel 42 during the rotation. The threaded column of the rotating member 31 is connected with the threaded hole 4211 of the code wheel 42 so that the code wheel 42 and the rotating member 31 can be tightly connected, the code wheel 42 and the rotating member 31 can rotate together, and looseness between the code wheel 42 and the rotating member 31 in the rotating process is avoided, and further detection errors are caused.

Referring to fig. 6 and 7, in some embodiments, the rotating member 31 includes a first threaded section 311 and a second threaded section 312, the second threaded section 312 is connected to the first threaded section 311, the moving member 32 is disposed on the first threaded section 311 and is threadedly connected to the first threaded section 311, and the code wheel 42 is threadedly connected to the second threaded section 312.

In this manner, the rotation member 31 is connected to the moving member 32 and the code wheel 42 by the first threaded section 311 and the second threaded section 312, respectively, the first threaded section 311 is connected to the moving member 32 so that the moving member 32 can move on the rotation member 31 in the axial direction of the rotation member 31, and the second threaded section 312 is connected to the code wheel 42 so that the code wheel 42 and the rotation member 31 rotate together.

Illustratively, taking the rotating member 31 as a lead screw, the second threaded section 312 of the rotating member 31 is used for being fixedly connected with the code wheel 42 so that the code wheel 42 rotates along with the rotating member 31, and the moving member 32 is sleeved on the first threaded section 311 of the rotating member 31 and moves along the axial direction of the rotating member 31. Thus, it is desirable that the first threaded section 311 occupies a greater portion of the length of the rotational member 31, or that the first threaded section 311 is longer than the second threaded section 312.

In one example, the second housing 12 can be screwed with a lead screw through the moving member 32, such that when the lead screw rotates once in the first direction, the moving member 32 moves on the lead screw by a pitch, thereby causing the second housing 12 to slide by a pitch to a side away from the first housing 11, and further obtaining a distance for the expansion portion 22 to expand to the housing assembly 10 to obtain a larger display area of the electronic device 100. In the process, the code wheel 42 rotates with the rotating member 31 in one turn in the first direction, the photoelectric counter 41 is converted into an electric signal according to the number of detected optical signals and transmitted back to the processor of the electronic device 100, and the processor of the electronic device 100 can calculate the distance away from the second shell 12.

In another example, when the lead screw rotates once in the second direction, the moving member 32 moves on the lead screw reversely by a pitch distance, so that the second shell 12 slides by a pitch distance to a side close to the first shell 11, and thus the distance for retracting the extension portion 22 into the housing assembly 10 is obtained, so as to obtain a small display area of the electronic device 100. In the process, the code wheel 42 rotates one turn in the second direction along with the rotating member 31, the photoelectric counter 41 is converted into an electric signal according to the number of detected optical signals and transmitted back to the processor of the electronic device 100, and the processor of the electronic device 100 can calculate the approaching distance of the second shell 12.

In addition, the photoelectric detection component 40 is further configured to detect a rotation direction of the rotation component 31, when the rotation component 31 rotates along a first direction, the moving component 32 drives the second shell 12 to slide relative to the first shell 11 so that the expansion portion 22 can be at least partially expanded out of the housing component 10, and when the rotation component 31 rotates along a second direction, the moving component 32 drives the second shell 12 to slide in a reverse direction relative to the first shell 11 so that the expansion portion 22 can be at least partially retracted into the housing component 10, where the first direction is opposite to the second direction. It is to be understood that, in the embodiments of the present application, the first direction may be a clockwise direction and the second direction may be a counterclockwise direction, and the first direction may also be a counterclockwise direction and the second direction may also be a clockwise direction, which is not limited herein.

It can be understood from the above description that, in the embodiment of the present application, the sliding distance of the second shell 12 relative to the first shell 11 is equal to the distance that the extension portion 22 is extended out of the shell assembly 10 or retracted into the shell assembly 10, that is, how much distance the extension portion 22 moves out of the shell assembly 10 when the second shell 12 moves away from the first shell 11, and how much distance the extension portion 22 moves into the shell assembly 10 when the second shell 12 moves closer to the first shell 11.

Referring to fig. 6, in some embodiments, the driving assembly 30 further includes a motor 33 and a gear set 34, the motor 33 is fixedly connected to the first housing 11, the gear set 34 is connected to the rotating member 31 and the motor 33, the motor 33 is configured to drive the rotating member 31 to rotate through the gear set 34, and the code wheel 42 and the gear set 34 are respectively located at two opposite ends of the rotating member 31.

Thus, the motor 33 can generate a driving force, the gear set 34 transmits the driving force to the rotating member 31 with a suitable magnitude, or the motor 33 drives the motor shaft to rotate under the action of the electric force, the motor shaft is connected with the gear set 34 and drives the gear set 34 to rotate, and the gear set 34 is connected with the rotating member 31 to drive and rotate the rotating member 31 to perform a rotating motion, thereby completing the functions of driving and transmission.

Specifically, the driving force can be generated by the motor 33, or the motor 33 rotates the motor shaft under the action of the electric force, and the motor shaft is connected with the gear set 34 and drives the gear set 34 to rotate. One of the gears of the gear set 34 may be fixedly connected to the rotating member 31, or one of the gears of the gear set 34 may be engaged with a tooth portion formed on the rotating member 31, and the motor 33 is configured to drive the rotating member 31 to rotate through the gear set 34, so as to drive the moving member 32 to move on the rotating member 31, and further drive the second shell 12 to slide relative to the first shell 11, so that the expanding portion 22 can be extended out of the housing assembly 10 or retracted into the housing assembly 10. In this way, the gear set 34 can drive the rotating member 31 to rotate, so that the stability and reliability of the rotation of the rotating member 31 can be improved, and the implementation mode is simple. And the coded disc 42 and the gear set 34 are respectively positioned at the opposite ends of the rotating member 31, so that mutual interference of the coded disc 42 and the gear set 34 can be avoided, and the stability and the reliability of the rotation of the rotating member 31 are further improved.

In this way, the first mounting portion 51 and the second mounting portion 52 can fix the rotating member 31 on the first shell 11, so that the rotating member 31 can drive the moving member 32 to move when rotating to drive the second shell 12 to move relative to the first shell 11.

Specifically, both ends of the rotation member 31 are mounted on the first mounting portion 51 and the second mounting portion 52, respectively, and the rotation member 31 is rotatable on the mounting seat 50. One end of the rotating member 31 may be disposed on the first mounting portion 51 to connect with the code wheel 42, the rotating member 31 and the code wheel 42 may be disposed at two ends of the first mounting portion 51, the first mounting portion 51 includes a through hole, and one end of the rotating member 31 passes through the through hole to connect with the code wheel 42, so that interference between the rotating member 31 and the code wheel 42 is avoided, and the code wheel 42 is guaranteed to rotate along with the rotating member 31. The other end of the rotating member 31 may be inserted into the second mounting portion 52, and the motor 33 and the gear set 34 may be disposed on the same side of the second mounting portion 52 as the rotating member 31, or disposed on two sides of the second mounting portion 52. The mounting seat 50 is fixedly connected to the first housing 11, and the rotating member 31 is rotatably mounted on the mounting seat 50, so that the moving member 32 can drive the second housing 12 to move relative to the first housing 11 during the rotation of the rotating member 31.

Referring to fig. 8, in some embodiments, the electronic device 100 further includes a guiding shaft 60 and a tensioning structure 70, one end of the expansion portion 22 is connected to the flat portion 21, the other end is connected to the tensioning structure 70, a middle portion of the expansion portion 22 is wound around the guiding shaft 60, and the tensioning structure 70 is used for tensioning the flexible display screen 20.

In this way, the guide shaft 60 and the tension structure 70 can guide the movement of the flexible display 20, and prevent the flexible display 20 from bending abnormally during the switching process between the two modes.

Specifically, the guide shaft 60 is 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 60, so that the guide shaft 60 may guide the extension portion 22 to enable the extension portion 22 to be smoothly extended or retracted when the extension portion 22 moves. The tensioning structure 70 is used to tension the flexible display 20 during the retraction of the flexible display 20. In the present embodiment, the guide shaft 60 may make the extension portion 22 substantially U-shaped, so that the extension portions 22 at both sides of the guide shaft 60 can be kept flat to improve the life of the flexible display 20. It is understood that in some embodiments, the electronic device 100 may not include the guide shaft 60, as long as the second shell 12 can move the extension portion 22 to expose the housing assembly 10.

Further, referring to fig. 8, 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 relative to the first shell 11 along with the second shell 12, one end of the tension rope 71 is fixedly connected to the expansion portion 22, the other end of the tension rope 71 is fixedly connected to the first shell 11, and a middle portion of the tension rope 71 is wound around 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 far away from 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 with the extension portion 22, the other end of the pulling rope 71 is fixedly connected with the first shell 11, the tensioning member 72 gradually releases the pulling rope 71, so that the extension portion 22 is gradually released, the extension portion 22 is gradually expanded out of the shell assembly 10 under the action of the second shell 12, the moving distance of the tensioning member 72 is the same as the moving stroke of the extension portion 22, in the process that the extension portion 22 is gradually expanded out of the shell assembly 10, the tensioning member 72 can tension the pulling rope 71, so that the flexible display screen 20 is tensioned.

When 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 with the expansion part 22, the other end of the pulling rope 71 is fixedly connected with the first shell 11, the expansion part 22 is gradually released from the second shell 12, the tensioning member 72 drives the pulling rope 71 to move towards one side of the first shell 11, so that the expansion part 22 is gradually retracted into the shell assembly 10, in such a process, the moving distance of the tensioning member 72 is the same as the moving stroke of the expansion part 22, in such a way, when the expansion part 22 is retracted and expanded into the shell assembly 10, the tensioning member 72 can tension the pulling rope 71, and therefore the flexible display screen 20 is tensioned. 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. 8, in some embodiments, the tension member 72 includes a pulley 721, the pulley 721 is disposed on the second housing 12, and the intermediate portion of the pull cord 71 is wound around the pulley 721.

Thus, the pulley 721 and the guide shaft 60 are both provided on the second housing 12, and both constitute a pulley assembly, thereby enabling the flexible display 20 to be smoothly unfolded and retracted.

Specifically, in the embodiment of the present application, the pulley 721 is rotatably provided on the second case 12, 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.

Referring to fig. 3, in some embodiments, the number of the driving assemblies 30 is two, the number of the photodetecting assemblies 40 is also two, the two driving assemblies 30 are respectively disposed on two symmetrical sides of the first housing 11, and each of the rotating members 31 corresponds to one photodetecting assembly 40.

As such, the driving assemblies 30 may be disposed at both ends of the guide shaft 60, respectively, so that the second housing 12 may be stably maintained while moving with respect to the first housing 11. The number of the photoelectric detection assemblies 40 is also two, so as to ensure that the actual output position of the two-side driving assembly 30 is accurately detected, and prevent the deviation movement and even the locking caused by the asynchronous driving of the two sides.

Specifically, the number of the driving assemblies 30 is two, and the two driving assemblies are respectively disposed on both sides of the electronic device 100. It will be appreciated that there are two photo-detection assemblies 40 cooperating with the driving assembly 30 to ensure that the actual output position of the two-sided driving assembly 30 is accurately detected, and the deviation motion and even the jamming caused by the asynchronous two-sided driving are avoided. The two photo-detection assemblies 40 may convert the detected light signals into electrical signals and transmit the electrical signals back to the processor of the electronic device 100. The processor of the electronic device 100 controls and adjusts the two driving assemblies 30 to output the same rotating speed externally according to the obtained electric signals, so that the two driving assemblies 30 drive the second shell 12 to move relative to the first shell 11 at the same rotating speed. The two driving assemblies 30 may provide at least two force applying points for the flexible display 20, or the two driving assemblies 30 respectively drive the upper and lower sides of the second shell 12 and the extension portion 22 to move towards one direction at the same time, so as to ensure smooth transmission when the extension portion 22 is at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10, and ensure smooth and reliable movement of the flexible display 20. Of course, in some embodiments, the number of the driving assembly 30 and the photo detection assembly 40 may also be one or more than two, and is not limited herein.

Referring to fig. 9 and 10, in some embodiments, the electronic device 100 further includes a position detecting assembly 80, the position detecting assembly 80 includes a hall sensor 81 and a magnetic member 82, one of the hall sensor 81 and the magnetic member 82 is mounted on the first housing 11, and the other is mounted on the second housing 12, and the hall sensor 81 is configured to cooperate with the magnetic member 82 to detect the relative position of the first housing 11 and the second housing 12.

As such, the position detecting member 80 can detect the relative positions of the flat portion 21 and the expanded portion 22 to determine whether the expanded portion 22 is moved to the specified position. For example, the position detecting member 80 may detect whether or not the extension portion 22 moves to the extreme position when moving to the side away from the flat portion 21; and it is possible to detect whether or not to move to the extreme position when the expanding portion 22 moves to the side near the flat portion 21. Thereby timely feeding back the position information to control the driving assembly 30 to stop working so as to prevent the motor 33 from being locked and even damaging the electronic device 100.

The position detecting assembly 80 includes a hall sensor 81 and a magnetic member 82, the magnetic member 82 may be a permanent magnet or an electromagnet, and the hall sensor 81 may detect the magnetism of the magnetic member 82. In some embodiments, the number of the magnetic members 82 may be two, the magnetic members 82 may include a first magnetic member 821 and a second magnetic member 822, the first magnetic member 821 and the second magnetic member 822 have different magnetism, the first magnetic member 821 and the second magnetic member 822 are respectively disposed at two extreme positions of the second housing 12 with respect to the first housing 11, and the hall sensor 81 is disposed at a position on the first housing 11 where the magnetic member 82 can be engaged. In this way, the hall sensor 81 can detect the relative position of the second housing 12 and the first housing 11 by sensing the position of the magnetic member 82.

Specifically, when the first housing 11 and the second housing 12 are overlapped (i.e., in the first configuration), the hall sensor 81 corresponds to the first magnetic member 821, the hall sensor 81 outputs the first position signal, the electronic device 100 is in the initial state, the display area is minimized, and the extension portion 22 is substantially completely hidden in the housing assembly 10. In this case, when the rotating member 31 is gradually driven by the driving assembly 30 to rotate so as to drive the second housing 12 to gradually move away from the first housing 11, the extension portion 22 gradually expands to the outside of the housing assembly 10, the display area of the electronic device 100 gradually increases, at this time, the first magnetic member 821 gradually moves away from the hall sensor 81, and the hall sensor 81 gradually moves close to the second magnetic member 822, and the first magnetic member 821 and the second magnetic member 822 have different magnetism. When the hall sensor 81 moves to a position opposite to the second magnetic member 822, the hall sensor 81 outputs a second position signal to indicate that the second housing 12 moves to the limit position (i.e., the second configuration), and the processor of the electronic device 100 receives the second position signal and controls the motor 33 of the driving assembly 30 to stop, at which time, the display area of the electronic device 100 is maximum.

On the contrary, when the first housing 11 and the second housing 12 are separated from each other (i.e. the second configuration), the hall sensor 81 corresponds to the second magnetic member 822 and outputs the second position signal, in such a case, when the driving assembly 30 gradually drives the rotating member 31 to rotate in the opposite direction so as to drive the second housing 12 to gradually approach the first housing 11, the expanding portion 22 is gradually retracted into the housing assembly 10, the display area of the electronic device 100 is gradually reduced, at this time, the second magnetic member 822 is gradually separated from the hall sensor 81, and the hall sensor 81 is gradually approached to the first magnetic member 821, when the first magnetic member 821 is moved to the position opposite to the hall sensor 81, the hall sensor 81 outputs the first position signal to indicate that the second housing 12 is moved to the limit position (i.e. the first configuration), the processor of the electronic device 100 receives the first position signal and controls the motor 33 of the driving assembly 30 to stop, at this time, the display area of the electronic device 100 is the smallest.

In the above embodiment, the first magnetic member 821 and the second magnetic member 822 are fixedly connected to the second case 12 at an interval, and the hall sensor 81 is fixedly connected to the first case 11. It is understood that, in other embodiments, the first magnetic member 821 and the second magnetic member 822 may be spaced apart from and fixedly connected to the second housing 12, and the hall sensor 81 may be fixedly connected to the first housing 11. In the embodiment of the present application, the first magnetic member 821 and the second magnetic member 822 only need to be capable of moving relative to the hall sensor 81 when the second housing 12 moves, and the details of the first magnetic member 821, the second magnetic member 822, and the hall sensor 81 are not limited herein.

In some embodiments, the number of the hall sensors 81 may be two, two hall sensors 81 may be respectively disposed at two extreme positions of the second housing 12 with respect to the first housing 11, and the magnetic member 82 may be disposed at a position on the first housing 11 where the magnetic member 82 may be engaged. In this way, the hall sensor 81 can detect the relative position of the second housing 12 and the first housing 11 by sensing the position of the magnetic member 82.

It is understood that in some embodiments, the position detecting assembly 80 may be other sensors, the hall sensor 81 may be replaced by an infrared sensor (not shown), and the magnetic member 82 may be replaced by a reflecting member (not shown) capable of reflecting infrared light and disposed on the extension portion 22. The infrared light reflected by the infrared sensor can be reflected back by the reflection of the reflection member, so that the infrared sensor can receive the infrared light reflected back by the reflection member to output a first position signal and a second position signal, thereby detecting the relative position of the second housing 12 and the first housing 11. In the embodiment of the present application, the number of the position detecting elements 80 is not limited, and the detection requirement may be satisfied.

The housing assembly 10 includes a flat portion 21 and an expanded portion 22, the flat portion 21 being slidably coupled to the expanded portion 22. The flexible display 20 includes a flat portion 21 exposed from the housing assembly 10 and an extension portion 22 capable of being hidden within the housing assembly 10, the flat portion 21 being connected to the flat portion 21. The driving assembly 30 includes a motor 33 and a gear set 34, the motor 33 drives the rotating member 31 to rotate through the gear set 34, the motor 33 is used for driving the rotating member 31 to rotate so as to drive the extending portion 22 to slide relative to the flat portion 21, so that the extending portion 22 can be at least partially extended out of the housing assembly 10 or retracted into the housing assembly 10 to adjust the display area of the electronic device 100. The photo detecting element 40 is used for detecting the rotation angle of the rotating member 31 to detect the sliding distance of the extending portion 22 relative to the flat portion 21 so as to detect the display area of the electronic device 100. And the electronic device 100 may detect the position of the second housing 12 with respect to the first housing 11 through the position detecting assembly 80 to detect the display area of the electronic device 100. Therefore, the position of the flexible display screen 20 is located, and the display area of the electronic device 100 is detected again. In this way, even if the sliding stroke of the extension portion 22 is relatively long, the detection of the two detection assemblies can achieve relatively high positioning accuracy to perform relatively precise detection and adjustment on the display area of the electronic device 100.
