Referring to fig. 4 and 6, the second portion 14 is disposed on the first portion 12, the second portion 14 is substantially rectangular, and the second portion 14 is formed with a receiving chamber 140. Specifically, the second portion 14 includes a slide 144, a second top plate 142, and a bottom plate 146. 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 is attached to the first top plate 122. The bottom plate 146 and the second top plate 142 are oppositely disposed and define a receiving chamber 140, and the receiving chamber 140 can be used for receiving the camera head 60. It should be noted that the term "fit" as used herein may be understood as contact between the two without affecting sliding movement between the two, or may be understood as a gap between the two within the assembly tolerance.

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. "beneath," "under" and "beneath" a first feature includes the first feature being directly beneath and obliquely beneath the second feature, or simply indicating 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 this embodiment, "the first part 12 and the second part 14 move away from each other" may be understood as 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 this embodiment, the first portion 12 and the second portion 14 can also move toward each other, and the movement of the two portions toward each other can 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; they may be directly connected or indirectly connected through intervening media, or may be connected through the use of two elements or the interaction of two elements. 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, 3 and 4, 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, 5 and 6, as first portion 12 and second portion 14 move apart (i.e., away from each other), first portion 12 and second portion 14 separate.

Referring to fig. 4 and 6, the reel 20 is rotatably disposed on the first portion 12, specifically, the reel 20 is rotatably disposed in the accommodating space 120 and exposed from the first opening 1222, that is, the reel 20 is mounted on the first portion 12 and can rotate relative to the first portion 12. The roller 20 is used to wind the flexible display assembly 30 and to interface with the return mechanism 40 such that the return mechanism 40 applies a return force to the flexible display assembly 30 to maintain the tendency of the flexible display assembly to wind up on the roller 20.

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

In addition, with continued reference to fig. 4 and 6, one end of the flexible display assembly 30 is fixedly attached to the second portion 14 and the other end is rolled up on the roll 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 winding shaft 20 disposed in the accommodating space 120.

In this manner, upon movement of the first portion 12 and the second portion 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. Therefore, the size of the screen display area of the electronic device 100 can be freely adjusted, the display part 301 of the flexible display screen assembly 30 can be expanded to improve the operation experience of a user when a large screen is needed, and meanwhile, the display part 301 can not be expanded when the large screen is not needed, so that the whole device is small in size and convenient to carry.

It will be appreciated that referring to fig. 4, in one instance, the first portion 12 and the second portion 14 are connected together in close proximity, in which case the display portion 301 of the flexible display screen assembly 30 is not extended and the electronic device 100 is in the narrow screen mode, in which case a portion of the flexible display screen assembly 30 is rolled up on the roller 20 and a portion is positioned above the first top panel 122 and exposed from the housing 10 for display. It should be noted 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 board 142 of the second portion 14, that is, a portion exposed from the housing 10.

Referring to fig. 6, 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 one end of the flexible display screen assembly 30 to move, 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 is an extreme position in which the display area of the electronic device 100 is the largest, i.e. the area of the set of flexible display screens 32 exposed from the housing 10 is the largest, i.e. the area of the display portion 301 of the flexible display screen assembly 30 is the largest, when both the second part 14 and the first part 12 are moved away from each other (as shown in fig. 6). When the first portion 12 and the second portion 14 are brought into close proximity and coupled together, 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. 4).

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. 4 and 6, 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.

Further, the flexible display screen 32 includes a first region 322 fixedly connected to the second top plate 142 and a second region 324 connected to the first region 322, the first region 322 corresponds to the second top plate 142, and the second region 324 is at least partially located in the accommodating space 120 of the first portion 12 and connected to the flexible support 34. The first region 322 may be fixedly connected to the second top plate 142 by an Optical Clear Adhesive (OCA).

The flexible support 34 is disposed at the bottom of the second region 324 and 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). Referring to fig. 4, when the electronic device 100 is in the narrow screen mode, the flexible support 34 and the second region 324 of the flexible display screen 32 are substantially completely rolled up on the roller 20.

It will be appreciated that in this embodiment, the spool 20 is positioned in correspondence with the first opening 1222, which is located on one side of the first portion 12, and the flexible display screen assembly 30 is rolled onto the spool 20. Like this, can prevent that flexible display screen assembly 30 from occupying the bigger space of accommodation space 120 to can provide more spaces for putting of electrical components such as mainboard 101 and battery, the effectual utilization ratio that has improved the space is favorable to piling up and putting of electrical components such as mainboard 101, battery.

Referring to fig. 4 and 6, 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. 6, 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, because the first top plate 122 and the second top plate 142 are attached to each other vertically, and the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, the thickness of the flexible supporting member 34 is equal to the thickness of the second top plate 142, so that the height difference between the first top plate 122 and the second top plate 142, that is, the gap between the flexible display screen 32 and the first top plate 122 is filled, and thus the flexible display screen 32 can be kept flat during movement, thereby avoiding the collapse phenomenon of the flexible display screen 32 when being touched when the electronic device 100 is in the expansion mode, and improving the operation experience of the user.

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 capable of being magnetized or the first upper plate 122 includes a metallic layer capable of being 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. 4 and fig. 6 to 8, in the present embodiment, the camera 60 may be disposed in the accommodating chamber 140 of the second portion 14, and the camera 60 may be fixedly connected to the second portion 14 and capture an image through the second portion 14. Specifically, the camera 30 may capture images through the bottom plate 146 of the second portion 14. That is, light can pass through the floor 146 of the second portion 14 to be received by the camera 60 so that the camera 60 can capture images through the second portion 60, and the camera 60 will follow the movement of the second portion 14 as the second portion 14 moves relative to the first portion 12. In this way, the size of the display area 301 of the flexible display screen assembly 30 can be adjusted without affecting the photographing and image capturing functions of the camera 60, so that the user can conveniently take a picture in any situation. Of course, it is understood that the camera 60 may be only partially located in the accommodating chamber 140, as long as the normal shooting and photographing functions of the camera 60 can be achieved, and the invention is not limited thereto.

Further, in order to enable the camera 60 to take pictures and images normally, a through hole corresponding to the camera 60 may be opened on the bottom plate 146 or the bottom plate 146 includes a light-transmitting area corresponding to the camera 60, the camera 60 is exposed from the through hole or images are collected through the light-transmitting area, that is, light may pass through the through hole or the light-transmitting area to be received by the camera 60, and the light-transmitting area may be made of a light-transmitting material such as glass.

In addition, referring to fig. 4 and fig. 6 to 8, the cover 50 includes a first connecting portion 52 and a second connecting portion 54, the first connecting portion 52 is fixedly connected to the bottom of the first portion 12 and closes the accommodating space 120, the second connecting portion 54 is fixedly connected to the bottom of the second portion 14, and the camera 60 can capture images through the second connecting portion 54. That is, the second connecting portion 54 is fixedly connected to the first portion 12, the second connecting portion 54 is fixedly connected to the second portion 14, the second connecting portion 54 is movable relative to the first connecting portion 52, and the camera 60 is capable of following the movement of the second portion 14.

Specifically, the first connecting portion 52 is detachably connected to the first portion 12, so that the first connecting portion 52 can be conveniently detached to repair and replace the electrical components such as the motherboard 101, the battery or the sensor stacked in the accommodating space 120. It is understood that, in other embodiments, the first connecting portion 52 and the first portion 12 may also be a unitary structure, and the two are integrally formed, and the specific arrangement manner is not limited herein. The second connection portion 54 may be fixedly or detachably connected to the bottom plate of the bottom plate 146, and the second connection portion 54 includes a light-transmitting portion 56 corresponding to the through hole or the light-transmitting area, that is, the camera 60, the through hole (or the light-transmitting area), and the light-transmitting portion 56 correspond to each other. In this way, the camera 60 can receive light through the through hole (or the light-transmitting region) and the light-transmitting portion 56 for image acquisition.

Referring to fig. 7, when the electronic device 100 is in the narrow-screen mode, that is, the first portion 12 and the second portion 14 move to the extreme positions, the first connecting portion 52 and the second connecting portion 54 are engaged to form the cover 50 of the electronic device 100. Referring to fig. 8, when the second portion 14 moves away from the first portion 12, the second connecting portion 54 is separated from the second connecting portion 54.

Specifically, referring to fig. 7 and 8, in such an embodiment, an arc-shaped concave portion 542 is formed on the first connecting portion 52, a convex portion 522 matching with the concave portion 542 is formed on the second connecting portion 54, and the convex portion 522 is also arc-shaped, when the electronic device 100 is in the narrow-screen mode (as shown in fig. 7), the concave portion 542 and the convex portion 522 are spliced together to realize splicing of the first connecting portion 52 and the second connecting portion 54. It is understood that the first connecting portion 52 and the second connecting portion 54 can be made into other shapes, for example, both of them are rectangular, and they can be directly spliced to form the cover 50, and for example, one of them can be formed with regularly arranged protrusions, and the other can be formed with grooves corresponding to the protrusions, so that when the electronic device 100 is in the expansion mode, the shape of the housing 10 can be enriched to improve the aesthetic feeling.

Further, in such an embodiment, the first connection portion 52 and the second connection portion 54 can be designed to have two different color effects, which can enrich the appearance effect of the electronic device 100.

Referring to fig. 9, a restoring mechanism 40 may also be disposed in the accommodating space 120, the restoring mechanism 40 is connected to the winding shaft 20, and the restoring mechanism 20 is configured to apply a restoring force to the flexible display panel assembly 30 to keep the flexible display panel assembly 30 in a tendency of being wound on the winding shaft 20.

Specifically, the return mechanism 40 applies a return force to the roller 20, and the roller 20 maintains the tendency of the flexible display screen assembly 30 to roll up on the roller 20 under the action of the return force. That is, when second portion 14 is not moved relative to first portion 12 by an external force, the restoring force of restoring mechanism 40 may cause spool 20 to rotate, thereby causing one end of flexible display screen assembly 30 to be wound onto spool 20, in which case first portion 12 and second portion 14 are fully mated and electronic device 100 is in the narrow screen mode.

When the second portion 14 is subjected to an external force and the external force is greater than or equal to the restoring force of the restoring mechanism 40, the second portion 14 moves away from the first portion 12, so as to drive the roller 20 to rotate against the restoring force to release the flexible display panel assembly 30, thereby expanding the display portion 301 of the flexible display panel assembly 30.

Further, referring to fig. 9, the restoring mechanism 40 may include an elastic element connected to the spool 20 and configured to apply a restoring force to the spool 20. The resilient member may be a spring, such as a torsion spring as shown in fig. 9. Of course, the elastic element may also be an element having elastic restoring force, such as rubber, and is not limited herein.

Referring to fig. 10, a detent structure 80 is disposed on the housing 10, the detent structure 80 being configured to limit rotation of the spool 20 when the second portion 14 is moved to a predetermined position relative to the first portion 12. That is, when second portion 14 is moved to a predetermined position relative to first portion 12, detent structure 80 may prevent retraction of second portion 14 and flexible display screen assembly 30 under the restoring force of restoring mechanism 40.

Specifically, referring to fig. 10, in the present embodiment, the locking structure 80 may include a locking block 82 formed on the first portion 12 and a locking groove 84 formed on the second portion 14, and when the second portion 14 moves to a predetermined position relative to the first portion 12, the locking block 82 is locked in the locking groove 84. Thus, even if the external force is removed from the second portion 14, the second portion 14 and the flexible display assembly 30 will not retract under the restoring force of the restoring mechanism 40 due to the engagement of the latch 82 and the slot 84. To ensure that the electronic device 100 is in the extended mode.

It should be noted that the "preset position" may be a relative position between the second portion 14 and the first portion 12 when the two portions move away from each other to the limit position, or may be any position before the limit position.

It is understood that referring to fig. 11, in other embodiments, the first portion 12 may be formed with a locking groove 84, and the second portion 14 may be formed with a locking block 82. In addition, in some embodiments, a latch may be formed on the first portion 12, a latch may be formed on the spool 20, and the latch may be engaged when the second portion 14 moves to the predetermined position, in which case, the latch and the latch may be engaged by a manual pressing manner or an electric driving manner, so that the spool does not rotate relative to the first portion, and the second portion 14 and the flexible display assembly 30 do not retract under the action of the return mechanism 40. Of course, in other embodiments, the detent structure 80 can also include a detent, and the return mechanism 40 can include a torsion spring, which can be locked to counteract the return force of the torsion spring when the second portion 14 moves to the predetermined position. In addition, it can be further understood that, in some embodiments, the detent structure 80 may also include an elastic assembly disposed on the first portion 12 and a first latching portion formed on the second portion 14, the elastic assembly may include a pressing piece, a spring and a second latching portion, the pressing piece is mounted on the first portion 12, the spring is connected with the pressing piece and the second latching portion, and the pressing piece may be used for driving the second latching portion to move to be latched with the first latching portion under the action of an external force through the spring, so as to define the relative position of the first portion 12 and the second portion 14. In this way, when the second portion 14 moves to the preset position, the user can press the pressing member to engage the first latching portion with the second latching portion, so as to prevent the second portion 14 from retracting under the restoring force of the restoring mechanism 40, and thus the electronic device 100 is kept in the extended mode. It will be appreciated that when the depressible member is depressed again, the first catch portion and the second catch portion disengage, thereby allowing the second portion 14 and the flexible display screen assembly 30 to retract under the action of the return mechanism 40 to return the electronic device 100 from the extended mode to the narrow screen mode.

Referring to fig. 4 and fig. 6, in the present embodiment, the driving mechanism 70 may be disposed in the accommodating space 120, the driving mechanism 70 is connected to the second portion 14, and the driving mechanism 70 is configured to drive the second portion 14 to move away from the first portion 12 to drive the flexible display panel assembly 30 to overcome the restoring force of the restoring mechanism 40, so as to expand the display portion 301 of the flexible display panel 32.

Specifically, the driving mechanism 70 may include a motor (not shown) and a transmission structure 72, the motor may be fixedly disposed in the accommodating space 120 of the first portion 12, and the transmission structure 72 is connected with the motor and the second portion 14.

The transmission structure 72 includes a transmission gear 722 and a rack portion 724. The transmission gear 722 is connected with a motor, and the rack portion 724 is connected withThe second portion 14 is fixedly attached and the rack portion 724 is engaged with the drive gear 722. Specifically, in the present embodiment, the rack portion 724 is integrally formed with the second top plate 142 of the second portion 14, that is, the rack portion 724 may be directly integrally formed on the lower surface of the second top plate 142. Can clean upSolution (II)In other embodiments, the rack portion 724 may be formed separately from the second portion 14 and then fixedly connected together by welding or the like, which is not limited herein.

In this embodiment, a motor may be used to drive the second portion 14 in motion relative to the first portion 12 via the transmission structure 72. Specifically, when the display area of the electronic device 100, that is, the display portion 301 of the flexible display panel assembly 30 needs to be expanded, the driving gear 722 may be driven by the motor to rotate, the driving gear 722 drives the second portion 14 to move away from the first portion 12 through the rack portion 724, and the second portion 14 drives one end of the flexible display panel assembly 30 to move, so as to overcome the restoring force of the restoring mechanism 40 to rotate the reel 20 to release the flexible display panel assembly 30, thereby expanding the display portion 301 of the flexible display panel assembly 30. It will be appreciated that in the present embodiment, the motor applies a force to the second part 14 through the transmission structure 72 to disengage the latch 82 of the first part 12 from the latch 84 of the second part 14, while the restoring force of the restoring mechanism 40 does not cause the latch 82 to disengage from the latch 84.

When the display part 301 of the flexible display screen assembly 30 needs to be reduced, the motor only needs to be rotated reversely, so as to drive the second part 14 to move oppositely relative to the first part 12, under such a condition, the second part 14 gradually releases the flexible display screen assembly 30, that is, the second part 14 does not apply acting force to the flexible display screen 30, so that the reel 20 rotates reversely under the action of the restoring force of the restoring mechanism 40, so as to gradually furl the flexible display screen assembly 30, and thus the retraction balance of the flexible display screen assembly 30 is kept.

It will be appreciated that when it is desired to reduce the size of the display portion 301, the motor may be turned on for a short period of time, as long as the latch 82 is disengaged from the slot 84, and then the motor may not be turned on, the flexible display screen assembly 30 will be retracted onto the spool 20 by the restoring force of the restoring mechanism 40, and the second portion 14 will also be moved towards the first portion 12 by the restoring force. In such a case, the transmission gear 722 is in an automatic rotation state, and due to the transmission gear 722 and the rack portion 724, the speed of the second portion 14 moving toward each other relative to the first portion 12 under the restoring force is not too fast, so that it is possible to avoid the second portion 14 moving too fast to cause a heavy collision with the first portion 12.

Furthermore, 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 by the rotation of the spool 20. That is, the spool 20 rotates to release the length of the flexible display screen assembly 30 by the amount of distance the end of the flexible display screen assembly 30 is pulled by the second portion 14, thus ensuring smooth movement of the flexible display screen assembly 30 without wrinkling.

Furthermore, it will be appreciated 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 driving mechanisms 70 may be two, and the number of the winding shafts 20 may also be two, and the two driving mechanisms 70 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. In this way, the two identical driving mechanisms 70 can be synchronously driven to realize the smooth movement of the second part 14, thereby ensuring the reliability of the movement of the electronic device 100 when expanding the display part 301 of the flexible display screen assembly 30.

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

Referring to fig. 3 to 6, 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. 3 and 4, the electronic apparatus 100 is in the narrow screen mode, and in the state shown in fig. 5 and 6, 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 up on the roller 20, and the other end is connected to the second portion 14, so that only a small portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrow, thereby facilitating carrying by a user.

When a user needs a larger display portion 301, the driving mechanism 70 can drive the second portion 14 to move away from the first portion 12, and at this time, the second portion 14 drives the flexible display screen assembly 30 to extend to overcome the restoring force of the restoring mechanism 40, so as to drive the reel 20 to rotate and 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 and smoothly 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 to operate to improve the operation experience of the user.

When the expansion mode needs to be switched to the narrow-screen mode, the motor of the driving mechanism 70 needs to be rotated reversely to drive the second portion 14 to move in the opposite direction relative to the first portion 12, so as to release the flexible display screen assembly 30, at this time, the reel 20 is rotated reversely correspondingly under the restoring force of the restoring mechanism 40, the flexible display screen assembly 30 is synchronously and smoothly wound, when the flexible display screen assembly moves to the limit position of the opposite movement between the first portion 12 and the second portion 14, the motor stops running, 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 assembly 30, and a return mechanism 40. The housing 10 comprises a first part 11 and a second part 13 which are relatively movable. The reel 20 is rotatably disposed in the first portion 11. One end of the flexible display screen assembly 30 is attached to the second portion 13 and the other end is provided on the spool 20. Wherein upon a movement of the first and second portions 11, 13 away from each other, the roller 20 is able to rotate to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. A return mechanism 40 is coupled to the roller 20, the return mechanism 40 being configured to apply a return force to the flexible display screen assembly 30 to maintain the tendency of the flexible display screen assembly 30 to roll up on the roller 20.

In summary, in the electronic device 100 of the embodiment of the present application, the return mechanism 40 is connected to the roll 20, and the return mechanism 40 can apply a return force to the flexible display assembly 30 to keep the flexible display assembly 30 in a tendency of being rolled up on the roll 20. When the second portion 14 moves away from the first portion 12 under the action of an external force, the roller 20 needs to overcome the restoring force of the restoring mechanism 40 to rotate to release the flexible display panel assembly 30, so that the restoring mechanism 40 can continuously apply the acting force to the roller 20 in the expansion process of the flexible display panel assembly 20, thereby ensuring that the flexible display panel assembly 30 keeps stable during the movement, and meanwhile, the display portion 30 of the flexible display panel assembly 30 can keep flat due to the existence of the restoring force, thereby preventing the flexible display panel assembly 30 from being wrinkled.
