In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Referring to fig. 1 to fig. 3, an electronic device 100 of the present embodiment includes a housing 10, a reel 20, a flexible display panel assembly 30, a limiting member 40, a cover 50, a camera 60, a main board 101, and a driving mechanism 70. The reel 20, the flexible display screen assembly 30, the position-limiting member 40, the cover 50, the camera 60, the main board, and the driving mechanism 70 may be disposed in the housing 10. It is understood that the electronic device 100 according to the embodiment of the present disclosure includes, but is not limited to, a mobile terminal such as a mobile phone, a tablet, or other portable electronic devices, and the electronic device 100 is taken as an example of a mobile phone in this document.

Referring to fig. 4 to 7, in the present embodiment, the housing 10 includes a first portion 12 and a second portion 14, and the first portion 12 and the second portion 14 can move relatively. Specifically, in the present embodiment, the first portion 12 and the second portion 14 are slidably coupled, that is, the second portion 14 is slidable relative to the first portion 12.

Referring to fig. 3 to 7, in an embodiment, the first portion 12 may be substantially rectangular, and the first portion 12 forms a receiving space 120. The accommodating space 120 can be used for accommodating the reel 20, the limiting member 40, the camera 60, the main board 101, the driving mechanism 70, and other components. Of course, referring to fig. 4 and fig. 6, the accommodating space 120 may also be used for stacking other electrical components of the electronic device 100, such as the battery 102 and the sub-board 103, and the sub-board 103 may be used for disposing electrical components such as a speaker and a microphone of the electronic device 100.

In order to achieve the light and thin structure, the space inside the electronic device 100 for stacking the electrical components is very limited, and the flexible display assembly 30 can be accommodated in the reel 20 disposed in the first portion 12 in this embodiment, which occupies a small space and provides a larger space for the stacking design of other electrical components.

Referring to fig. 3 and 8, the first portion 12 includes a first top plate 122, the first top plate 122 defines a first opening 1222 and a second opening 1224, and the first opening 1222 and the second opening 1224 are both connected to the accommodating space 120. The opening direction of the first opening 1222 is perpendicular to the direction of the second opening 1224. The first opening 1222 is used for passing an end of the flexible display screen assembly 30 to connect the end of the flexible display screen assembly 30 with the reel 20, and the second opening 1224 is used for exposing the driving mechanism 70 from the accommodating space 120 to connect with the second portion 12.

Specifically, referring to fig. 3 and 8, in the present embodiment, the first opening 1222 may be opened along a longitudinal direction of the electronic device 100, and the second opening 1224 may be opened along a transverse direction of the electronic device 100. The number of the second openings 1224 may be two, and the two second openings 1224 are located at both sides of the first top plate 122 and are symmetrically arranged in the longitudinal direction.

The second portion 14 is movable relative to the first portion 12 in a lateral direction of the electronic device 100. In addition, the first portion 12 defines a sliding slot 124, and the sliding slot 124 is configured to cooperate with the second portion 14 to enable the second portion 14 to slide relative to the first portion 12.

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. Furthermore, the terms "first", "second" and "first" 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 present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 3, 5 and 7, the second portion 14 is located on the first portion 12, the second portion 14 may also be substantially rectangular, and the second portion 14 includes a sliding portion 144 and a second top plate 142. The sliding portions 144 are connected to both sides of the second top plate 142 in the longitudinal direction and are substantially symmetrically disposed. The sliding portion 144 is adapted to cooperate with the sliding slot 124 of the first portion 12 to achieve a sliding connection between the first portion 12 and the second portion 14, and the second top plate 142 abuts against the first top plate 122. It should be noted that, in this context, "fit" may be understood as the contact between the two without affecting the sliding between the two, or may be understood as the gap between the two being within the assembling error range.

It should be noted that in this application, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact with each other through another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

It will be appreciated that in this embodiment, the second portion 14 is slidable relative to the first portion 12 to move away from or towards the first portion 12. In the present embodiment, "the first part 12 and the second part 14 move away from each other" may be understood as that the second part 14 slides relative to the first part 12 and the sliding direction is away from the first part 12. In addition, in the present embodiment, the first portion 12 and the second portion 14 may also move toward each other, and the movement of the two toward each other may be understood as the second portion 14 sliding with respect to the first portion 12 with the sliding direction toward the first portion 12.

It is further noted that, in the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, e.g. as 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. 1, 4 and 5, in the present embodiment, when the first portion 12 and the second portion 14 move toward each other to the limit position (i.e., when the first portion 12 and the second portion 14 approach each other until the first portion 12 and the second portion 14 are fit together), the first portion 12 and the second portion 14 are integrally formed into a substantially rectangular housing 10. Referring to fig. 2, 6 and 7, as first portion 12 and second portion 14 move apart (i.e., away from each other), second portion 14 moves away from first portion 12.

Referring to fig. 3, 5 and 7, the reel 20 is rotatably disposed in the first portion 12, and specifically, the reel 20 is rotatably disposed in the accommodating space 120. That is, the spool 20 is mounted to the first portion 12 and is rotatable relative to the first portion 12. The roller 20 is adapted to be coupled to a drive mechanism 70 to enable the roller 20 to rotate relative to the first portion 12 to release or retract the flexible display screen assembly 30 upon actuation of the drive mechanism 70.

It will be appreciated that the rotational positioning of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12, or may refer to the spool 20 being mounted on the first portion 12 via other media.

In addition, with continued reference to fig. 5 and 7, one end of the flexible display panel assembly 30 is connected to the second portion 14, in this embodiment, the end is fixedly connected to the second portion 14, in other embodiments, the end can also be connected to the second portion 14 through a movable mechanism, for example, the movable mechanism can be a structure for adjusting the tightness of the flexible display panel assembly 30. The other end of the flexible display assembly 30 is disposed on the spool 20 so that a portion of the flexible display assembly 30 can be wound on the spool 20. The roller 20 may be used to take up the flexible display screen assembly 30 and release the flexible display screen assembly 30. Wherein upon a movement of the first and

second portions

12, 14 away from each other, the roller 20 is able to rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. Specifically, one end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, and the other end thereof passes through the first opening 1222 of the first portion 12 and then is connected to the reel 20 disposed in the accommodating space 120.

In this manner, upon a movement of the first and

second portions

12, 14 away from each other, the spool 20 can rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. Thus, the size of the screen display area of the electronic device 100 can be freely adjusted, and the display part 301 can be not expanded when a large screen is not needed, so that the whole device is small in size and convenient to carry; the display portion 301 of the flexible display screen assembly 30 may be expanded to enhance the user's operational experience when a large screen is desired.

It can be understood that referring to fig. 5, in a situation where the first portion 12 and the second portion 14 are closely connected together, in such a situation, the display portion 301 of the flexible display panel assembly 30 is not expanded, the unexpanded portion of the original display portion 301 is accommodated in the accommodating space 120, and the electronic device 100 is in the narrow-screen mode, in which a portion of the flexible display panel assembly 30 is rolled on the roller 20, and a portion is located above the first top plate 122 and exposed from the housing 10 for displaying. Note that in the present embodiment, the "display portion 301 of the flexible display panel assembly 30" may be understood as a portion located above the second top plate 142 of the second portion 14, that is, a portion exposed from the housing 10.

Referring to fig. 7, when the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the first portion 12 and the second portion 14 move away from each other, so that the second portion 14 drives the flexible display screen assembly 30 to extend, and at this time, the reel 20 can release the flexible display screen assembly 30, so that the display portion 301 of the flexible display screen assembly 30 is enlarged, thereby improving the operation experience and the demand of the user. In such a case, the electronic device 100 is in the extended mode.

It will be appreciated that there are extreme positions in which the display area of the electronic device 100 is maximized, i.e. the area of the set of flexible display screens 32 exposed from the housing 10 is maximized, i.e. the area of the display portion 301 of the flexible display screen assembly 30 is maximized, when both the second part 14 and the first part 12 are moved away from each other (as shown in fig. 7). When the first portion 12 and the second portion 14 are brought together in close proximity and coupled, the display area of the electronic device 100 is minimized, i.e., the display portion 301 of the flexible display screen assembly 30 is minimized in area (as shown in fig. 5).

In this embodiment, one end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, which may mean that one end of the flexible display screen assembly 30 is directly fixed to the second portion 14, or that the flexible display screen assembly 30 is fixed to the second portion 14 through other media. One end of the flexible display screen assembly 30 is not movable relative to the second portion 14.

In the embodiment of the present application, one end of the flexible display screen assembly 30 refers to a first edge of the flexible display screen assembly 30, and the other end of the flexible display screen assembly 30 refers to a second edge of the flexible display screen assembly 30, the second edge being disposed opposite to the first edge.

Specifically, referring to fig. 3, 5 and 7, the flexible display panel assembly 30 includes a flexible display panel 32 and a flexible supporting member 34, wherein the flexible display panel 32 and the flexible supporting member 34 are stacked and fixedly connected.

Referring to fig. 5, the flexible display screen 32 includes a first area 322 and a second area 324 connected to the first area 322. The first region 322 is attached to the second top plate 142, the first region 322 corresponds to the second top plate 142, and the first region 322 can be fixedly connected to the second top plate 142 by an Optical Clear Adhesive (OCA). The second region 324 is at least partially disposed in the receiving space 120 of the first portion 12 and attached to the flexible support 34.

The flexible support 34 is disposed at the bottom of the second region 324 and completely covers the second region 324, and the flexible support 34 may also be fixedly connected to the second region 324 by an Optical Clear Adhesive (OCA). In the example shown in fig. 5 and 7, the flexible support 34 completely covers and extends beyond the second region 324, and the excess portion of the flexible support 34 is connected to the spool 20, i.e., the excess portion is rolled up on the spool 20. Referring to fig. 5, when the electronic device 100 is in the narrow screen mode, the flexible support 34 is wound on the reel 20, and the flexible display screen 32 is substantially "U" shaped. Thus, the supporting area of the flexible supporting metal 34 is large, so that the phenomenon of pressing deformation and the like of the flexible display screen 32 can be reduced.

In this way, when the electronic device 100 is in the narrow-screen mode (i.e. when the first portion 12 and the second portion 14 move towards each other to the extreme positions), only the flexible supporting member 34 is wound up by the winding shaft 20, and the flexible display screen 32 is not directly wound up by the winding shaft 20, so that the degree and the number of times that the flexible display screen 32 is bent can be reduced, and the service life of the flexible display screen 32 is prolonged. Of course, it is understood that in other embodiments, the flexible display 32 may be completely corresponding to the flexible support 34 and then both are connected to the reel 20, and the reel 20 may simultaneously reel in and simultaneously reel out both the flexible support 34 and the flexible display 32, and the specific arrangement is not limited herein. In addition, the flexible supporting member 34 completely covers the second region 324, and the supporting area of the flexible supporting member 34 is larger, so that the phenomenon of pressing deformation and the like of the flexible display screen 32 can be reduced.

In the present embodiment, the flexible display 32 has a substantially U-shape, and the main board 101, the battery 102, the sub-board 103, and the electric components such as the sensor of the electronic device 100 can be accommodated in the space surrounded by the flexible display unit 30. Like this, the mode of setting up of flexible display screen subassembly 30 can not influence the electric elements's such as mainboard 101 and battery 102 putting, the effectual utilization ratio that improves the space is favorable to piling up and putting of electric elements such as mainboard 101, battery 102.

Referring to fig. 5 and 7, in the present embodiment, when the first portion 12 and the second portion 14 move away from each other, the flexible supporting member 34 abuts against the first portion 12 to keep the display portion 301 of the flexible display screen 32 flat.

Specifically, when the first portion 12 and the second portion 14 are separated, the flexible support 34 is disposed opposite the first top plate 122 and abuts the first top plate 122. The flexible support 34 is located between the flexible display screen 32 and the first top plate 122 and fills a gap between the flexible display screen 32 and the first top plate 122. That is, the thickness of flexible support 34 is equal to the distance between the upper surface of first portion 12 and the upper surface of second portion 14.

It can be understood that, referring to fig. 7, when the first portion 12 and the second portion 14 move away from each other, a height difference exists between the upper surface of the first top plate 122 and the upper surface of the second top plate 142, the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, and at this time, the flexible supporting member 34 abuts against the first top plate 122 of the first portion 12, that is, the flexible supporting member 34 fills a gap between the flexible display screen 32 and the first top plate 122. That is, since the first top plate 122 and the second top plate 142 are attached to each other, the flexible display screen 32 is fixedly attached to the upper surface of the second top plate 142. Therefore, the thickness of the flexible support 34 equal to the thickness of the second top board 142 may fill the height difference between the first top board 122 and the second top board 142, that is, fill the gap between the flexible display screen 32 and the first top board 122, so that the flexible display screen 32 can be kept flat when moving, thereby avoiding the collapse phenomenon of the flexible display screen 32 when being touched and pressed when the electronic device 100 is in the expansion mode, and improving the operation experience of the user.

In addition, with continued reference to fig. 3, 5 and 7, a first tooth portion 342 is formed at the bottom of the flexible supporting member 34, and the first tooth portion 342 is configured to engage with the position-limiting member 40 so as to support the flexible display panel assembly 30 at the position-limiting member 40 and keep the flexible display panel assembly 30 moving smoothly.

In addition, in the present embodiment, the flexible support 34 may be made of a magnetic material, the first upper plate 122 may be made of a metallic material that can be magnetized, or the first upper plate 122 includes a metallic layer that can be magnetized coated on a surface thereof. In this way, the flexible support member 34 may be attached to the first top plate 122 when the second portion 14 is moved away from the first portion 12 to expand the display portion 301 of the flexible display screen assembly 30. This prevents misalignment or play of the flexible display assembly 30 during operation.

Referring to fig. 5, 7 and 8, the position-limiting member 40 is rotatably disposed in the accommodating space 120 of the first portion 12 and exposed from the first opening 1222, the middle portion of the flexible display panel assembly 30 is wound around the position-limiting member 40, and the position-limiting member 40 is used for limiting the shape of the flexible display panel assembly 30.

Specifically, the position-limiting member 40 is in a cylindrical shape, and a second tooth portion 42 is formed on a circumference of the position-limiting member 40, and the second tooth portion 42 is configured to engage with the first tooth portion 342 on the flexible supporting member 34 to support the flexible display panel assembly 30 and guide expansion of the flexible display panel assembly 30. It is understood that the middle portion of the flexible display screen assembly 30 may be understood as the portion located between the two ends of the flexible display screen assembly 30.

In this way, the position-limiting member 40 can limit the shape of the flexible display assembly 30, so that the display portion 301 of the flexible display assembly 30 can be in a flat state, i.e., the flexible display assembly 30 can be kept in a U-shaped state. In addition, the engagement of the position-limiting member 40 with the flexible supporting member 34 can both support the flexible display assembly 30 and guide the flexible display assembly 30 to keep the flexible display assembly 30 moving smoothly when the second portion 14 moves the flexible display assembly 30.

Specifically, in the present embodiment, the limiting member 40 is a guide gear, the limiting member 40 is disposed at a position corresponding to the first opening 1222, the middle portion of the flexible display panel assembly 30 is wound around the limiting member 40, and the first tooth portion 342 and the second tooth portion 42 of the flexible support 34 are engaged. That is, one end of the flexible display panel assembly 30 is fixedly connected to the second portion 14, and the other end thereof passes through the first opening 1222 and is connected to the reel 20 after passing through the limiting member 40. When the second portion 14 moves one end of the flexible display screen 32, the limiting member 40 is gradually rotated by the flexible support member 34, and the reel 20 gradually releases one end of the flexible support member 34.

It is understood that, in other embodiments, the limiting member 40 may not be formed with the second tooth portion 42, but directly be an optical axis or a roller, the flexible supporting member 34 may not be formed with the first tooth portion 342, the limiting member 40 and the flexible supporting member 34 are directly connected in a rolling manner, and the flexible display panel assembly 30 directly bypasses the optical axis or the roller, so that the limiting member 40 can also support and guide the flexible display panel 32.

Referring to fig. 5, 7 and 10, in the present embodiment, the camera 60 may be disposed in the accommodating space 120 of the first portion 12, the cover 50 is connected to the first portion 12 and covers the accommodating space 120, and the camera 60 can capture images through the cover 50. That is, in this embodiment, the first portion 12 is integral with the cover 50, and the camera 60 does not follow the movement when the second portion 14 moves relative to the first portion 12, and the camera 60 is located at an intermediate position of the entire flexible display screen 32 when in the extended mode.

In the present embodiment, the cover 50 is detachably connected to the first portion 12, so that the cover 50 can be easily detached to repair and replace the electrical components such as the motherboard 101, the battery 102, or the sensor stacked in the accommodating space 120. It is understood that in other embodiments, the cover 50 and the first portion 12 may be a unitary structure, and the two are integrally formed, and the specific arrangement is not limited herein.

In addition, referring to fig. 11 and 12, the cover 50 may be formed with a light-transmitting portion 56 corresponding to the position of the camera 60, and light can be transmitted through the light-transmitting portion 56 to be received by the camera 60, so that the camera 60 can capture images through the cover 50 to shoot outside. In this way, the light-transmitting portion 56 can protect the camera 60 without affecting the shooting effect of the camera 60, thereby preventing the camera 60 from being exposed outside the housing 10 directly and causing accidental scratching of the camera 60. In this case, the camera 60 may be a rear camera of a mobile phone, and the rear camera may capture an image through the light-transmitting portion 56 of the cover 50.

It is understood that in other embodiments, the reel 20 may be directly connected to the motor shaft of the second motor or may be connected to the motor shaft of the second motor through a single transmission gear or more transmission gears, and is not limited herein.

In this embodiment, when the display area of the electronic device 100, that is, the display portion 301 of the flexible display screen assembly 30, needs to be expanded, the first motor drives the first transmission gear 723 to rotate, the first transmission gear 723 drives the second portion 14 to move away from the first portion 12 through the rack 724, the second portion 14 drives the flexible display screen assembly 30 to extend, that is, one end of the flexible display screen assembly 30 is driven to move away from the first portion 12, the flexible display screen assembly 30 drives the reel 20 to rotate to release the flexible display screen assembly 30, and therefore the purpose of expanding the display portion 301 of the flexible display screen assembly 30 is achieved. It should be noted that, in the present embodiment, during the process of expanding the display portion 301, the second motor is in the off state, and the scroll 20 is in the free state, that is, the scroll 20 can rotate freely under the driving of the flexible display panel assembly 30. Of course, in some embodiments, the second motor may be turned on to synchronously drive the spool 20 to release the flexible display assembly when the first motor drives the second portion 14 to move away from the first portion 12.

When the display portion 301 of the flexible display screen assembly 30 needs to be reduced, the second motor can drive the third transmission gear 744 to rotate, so as to drive the second transmission gear 743 to rotate, thereby driving the reel 20 to rotate to reel the flexible display screen assembly 30, and the flexible display screen assembly 30 can drive the second portion 14 to move in opposite directions relative to the first portion 12, thereby achieving the purpose of reducing the display portion 301 of the flexible display screen assembly 30. It should be noted that during the process of reducing the display portion 301, the first motor is in the off state, and the first transmission gear 723 is in the free state, that is, the first transmission gear 723 can rotate under the driving of the second portion 14 when the second portion 14 moves away from the first portion 12. Of course, in some embodiments, the first motor may be turned on, and the second motor may be turned to drive the roller 20 to rotate to wind up the flexible display assembly. The first motor synchronously drives the second part 14 to move towards the first part 12.

It will be appreciated that in this embodiment, the travel of the second portion 14 per unit of time is equal to the length of the flexible display screen assembly 30 released or retracted by the rotation of the spool 20. That is, the length of the spool 20 is rotated to release the length of the flexible display assembly 30 by the distance the second portion 14 moves relative to the first portion 12 and the length of the spool 20 is rotated to take up the length of the flexible display assembly by the distance the second portion 14 moves relative to the first portion 12.

Furthermore, it can be further understood that, in some embodiments, in order to ensure the smoothness of winding and releasing the flexible display screen assembly 30 by the winding shaft 20, the number of the first driving mechanisms 72 and the number of the second driving mechanisms 74 may be two, the number of the winding shafts 20 is also two, the two first driving mechanisms 72 may be symmetrically disposed in the accommodating space 120 along the longitudinal direction of the electronic device 100 and respectively connected to the second portion 14, and the two second driving mechanisms 74 may be symmetrically disposed in the accommodating space 120 along the longitudinal direction of the electronic device 100 and also respectively connected to the two winding shafts 20. In this way, the two identical first driving mechanisms 72 can drive the smooth movement of the second portion 14 synchronously and the two identical second driving mechanisms 74 can realize the synchronous and smooth rotation of the two reels 20, thereby ensuring the reliability of the movement of the electronic device 100 when the display portion 301 of the flexible display screen assembly 30 is expanded.

Next, the operation principle of the electronic device 100 according to the present embodiment will be described.

Referring to fig. 4 to 7, as mentioned above, the electronic device 100 can be switched between the narrow screen mode and the extended mode. In the state shown in fig. 4 and 5, the electronic apparatus 100 is in the narrow screen mode, and in the state shown in fig. 6 and 7, the electronic apparatus 100 is in the extended mode. When in the narrow screen mode, the first portion 12 and the second portion 14 cooperate with each other to form the housing 10, one end of the flexible display screen assembly 30 is rolled on the roller 20, and the other end is fixedly connected to the second portion 14, at this time, only a small portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrow, so that the flexible display screen assembly is convenient for a user to carry.

When a user needs a larger display portion 301, the first driving mechanism 72 can drive the second portion 14 to move away from the first portion 12, at this time, the second portion 14 drives the flexible display screen assembly 30 to extend, and the flexible display screen assembly 30 drives the reel 20 to rotate to release the flexible display screen assembly 30, so that the portion of the flexible display screen assembly 30 hidden in the housing 10 is gradually pulled out by the second portion 14 (i.e., moves from the state shown in fig. 4 to the state shown in fig. 6), thereby achieving the purpose of expanding the display portion 301 of the flexible display screen assembly 30, and at this time, the area of the display portion 301 is larger, which can facilitate the user operation to improve the operation experience of the user.

When the expansion mode needs to be switched to the narrow-screen mode, the second driving mechanism 74 drives the winding shaft 20 to rotate, so as to gradually take up the flexible display screen assembly 30, the flexible display screen assembly 30 drives the second portion 14 to move relative to the first portion 12, the portion of the flexible display screen assembly 30 located outside the housing 10 is gradually pulled back into the accommodating space 120 of the first portion 12, when the portion moves to the limit position of the opposite movement between the first portion 12 and the second portion 14, the second driving mechanism 74 stops operating, and the electronic device 100 returns to the narrow-screen mode.

In summary, the electronic device 100 of the present embodiment includes a housing 10, a scroll 20, a flexible display panel assembly 30, a first driving mechanism 72, and a second driving mechanism 74. The housing 10 includes a first portion 12 and a second portion 14 that are capable of relative movement. The spool 20 is rotatably disposed in the first portion 12. One end of the flexible display screen assembly 30 is attached to the second portion 14 and the other end is provided on the spool 20. A first drive mechanism 72 is connected to the second portion 14, the first drive mechanism 72 being adapted to drive the second portion 20 away from the first portion 12 to rotate the spool 20 to release the flexible display assembly 30, thereby extending the display portion 301 of the flexible display assembly 30. A second drive mechanism 74 is coupled to the roller 20, the second drive mechanism 74 being configured to drive the roller 20 to rotate to retract the flexible display assembly 30 to reduce the display portion 301 of the flexible display assembly 30.

In summary, in the electronic device 100 of the embodiment of the present application, the first driving mechanism 72 can drive the second portion 14 to move away from the first portion 12 to drive one end of the flexible display assembly 30 to move, and thus drive the roller 20 to rotate to release the other end of the flexible display assembly 30 to expand the display portion 301 of the flexible display assembly 30. The second drive mechanism 74 is capable of driving the spool 20 to rotate to retract one end of the flexible display screen assembly 30 and thereby move the second portion 14 relative to the first portion 12 to retract the display portion 301 of the flexible display screen assembly 30. Thus, the arrangement of the two driving mechanisms can ensure the smoothness and reliability of the movement of the flexible display screen assembly 30 when the electronic device 100 expands or contracts the display part 301 of the flexible display screen assembly 30, and can also ensure that the flexible display screen assembly 30 is not easy to wrinkle in the extending and retracting processes.
