Referring to fig. 4 to 6, 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 are capable of relative movement. Specifically, in the present embodiment, the first portion 12 and the second portion 14 are slidably connected, that is, the second portion 14 is capable of sliding with respect to the first portion 12.

Referring to fig. 4 and 6, the first portion 12 is substantially rectangular, and the first portion 12 is formed with a receiving space 120. The accommodating space 120 may be used for accommodating components such as the reel 20, the restoring mechanism 40, the camera 60, the main board 101, and the driving mechanism 70. Of course, referring to fig. 3 and 5, 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 light and thin electronic device 100, the space for stacking electrical components is very limited, and the flexible display assembly 30 can be accommodated by the reel 20 and the restoring mechanism 40 disposed in the first portion 12 in this embodiment, which occupies a small space and can provide a larger space for stacking other electrical components.

Further, the first portion 12 includes a first top plate 122, and the first top plate 122 is provided with a first opening 1222 and a second opening (not shown), where the first opening 1222 and the second opening are both communicated with the accommodating space 120. The first opening 1222 is opened in a direction perpendicular to the second opening. The first opening 1222 is used for allowing one end of the flexible display screen assembly 30 to pass through so that one end of the flexible display screen assembly 30 is connected with the reel 20, and the second opening is used for allowing the driving mechanism 70 to be exposed from the accommodating space 120 so as to be connected with the second portion 12.

The number of the second openings is two, and the two second openings are located at two symmetrical sides of the first top plate 122. In particular, referring to fig. 2 and 7, in the present embodiment, the first opening 1222 may be opened along a longitudinal direction of the electronic device 100, the second opening may be opened along a lateral direction of the electronic device 100, and the second portion 14 may move along the lateral direction of the electronic device 100 relative to the first portion 12. In addition, the first portion 12 is provided with a sliding slot 124, the sliding slot 124 being adapted 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 should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 4 and 6, the second portion 14 is disposed on the first portion 12, the second portion 14 is also 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 disposed substantially symmetrically. The sliding portion 144 is configured 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 disposed opposite and define a receiving chamber 140, and the receiving chamber 140 is operable to receive the camera 60. It should be noted that the fitting referred to herein may be understood as contacting the two without affecting the sliding therebetween, or may be understood as a gap therebetween within the assembly error range.

It is noted that in the present application, unless explicitly specified and limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but rather being in contact with each other by way of further features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level 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 portion 12 and the second portion 14 are moved apart" is understood to mean that the second portion 14 slides relative to the first portion 12 and the sliding direction is away from the first portion 12. In addition, in the present embodiment, the first portion 12 and the second portion 14 may also move in opposite directions, and the two moving in opposite directions may be understood as that the second portion 14 slides relative to the first portion 12 and the sliding direction faces the first portion 12.

It should also be noted that in the description of the present application, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

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 extreme positions (i.e. when the first portion 12 and the second portion 14 approach each other to the point where the first portion 12 and the second portion 14 are engaged, the first portion 12 and the second portion 14 integrally form a substantially rectangular housing 10. Referring to fig. 2, 5 and 6, when the first portion 12 and the second portion 14 are moved apart (i.e., away from each other), the first portion 12 and the second portion 14 are separated.

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

It is understood that the rotational disposition 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 through other media.

In addition, with continued reference to fig. 4 and 6, the flexible display assembly 30 is fixedly attached at one end to the second portion 14 and is wound up on the spool 20 at the other end. The reel 20 may be used to roll up the flexible display assembly 30 and release the flexible display assembly 30. Wherein upon movement of the first portion 12 and the second portion 14 apart, the spool 20 is rotatable to release the flexible display assembly 30 to expand the display portion 301 of the flexible display assembly 30. Specifically, one end of the flexible display assembly 30 is fixedly connected to the second portion 14, and the other end is connected to the reel 20 disposed in the accommodating space 120 after passing through the first opening 1222 of the first portion 12.

In this manner, upon movement of the first portion 12 and the second portion 14 apart, the spool 20 can be rotated to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. In this way, the size of the screen display area of the electronic device 100 can be freely adjusted, the display portion 301 of the flexible display screen assembly 30 can be expanded when a large screen is required to be used to improve the operation experience of a user, and meanwhile, the display portion 301 can not be expanded when the large screen is not required to be used, so that the whole display 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 closely coupled together, in which case the display portion 301 of the flexible display assembly 30 is not expanded, and the electronic device 100 is in a narrow screen mode, where a portion of the flexible display assembly 30 is rolled up on the spool 20 and a portion is above the first top plate 122 and exposed from the housing 10 for display. In this embodiment, "the display portion 301 of the flexible display screen 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. 6, when the display portion 301 of the flexible display assembly 30 needs to be expanded, the first portion 12 and the second portion 14 are moved away from each other, so that the second portion 14 drives one end of the flexible display assembly 30 to move, and at this time, the reel 20 can release the flexible display assembly 30, so that the display portion 301 of the flexible display assembly 30 is enlarged, and thus the operation experience and the requirements of the user are improved. In such a case, the electronic device 100 is in the extended mode.

It will be appreciated that there is a limit to the movement of the second portion 14 and the first portion 12 apart, where the display area of the electronic device 100 is greatest, i.e., the area of the set of flexible display screens 32 exposed from the housing 10 is greatest, i.e., the area of the display portion 301 of the flexible display screen assembly 30 is greatest (as shown in fig. 6). When the first portion 12 and the second portion 14 are brought together in close proximity and in a connected fit, the display area of the electronic device 100 is minimal, i.e., the display portion 301 of the flexible display assembly 30 is minimal in area (as shown in fig. 4).

One end of the flexible display assembly 30 is fixedly connected to the second portion 14, which may refer to that one end of the flexible display assembly 30 is directly fixed to the second portion 14, or may refer to that the flexible display assembly 30 is fixed to the second portion 14 through other mediums. One end of the flexible display assembly 30 is not movable relative to the second portion 14.

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

In particular, referring to fig. 4 and 6, the flexible display assembly 30 includes a flexible display 32 and a flexible support 34, the flexible display 32 being stacked and fixedly connected to the flexible support 34.

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 adhesive (Optically Clear Adhesive, OCA).

The flexible support 34 is disposed at the bottom of the second area 324 and covers the second area 324, and the flexible support 34 may also be fixedly connected with the second area 324 through optical cement (Optically 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 32 are substantially entirely rolled up on the spool 20.

It will be appreciated that in this embodiment, the spool 20 is positioned corresponding to the first opening 1222 on one side of the first portion 12, and the flexible display assembly 30 is rolled up on the spool 20. In this way, the flexible display screen assembly 30 can be prevented from occupying a larger space of the accommodating space 120, so that more space can be provided for placing the electric elements such as the main board 101 and the battery, the space utilization rate is effectively improved, and stacking and placing of the electric elements such as the main board 101 and the battery are facilitated.

Referring to fig. 4 and 6, in the present embodiment, the flexible support 34 abuts the first portion 12 to keep the display portion 301 of the flexible display 32 flat during the separation movement of the first portion 12 and the second portion 14.

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 conforms to 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 the gap between the flexible display screen 32 and the first top plate 122. That is, the thickness of the flexible support 34 is equal to the distance between the upper surface of the first portion 12 and the upper surface of the second portion 14.

It will be appreciated that referring to fig. 6, when the first portion 12 and the second portion 14 are moved away from each other, there is a height difference between the upper surface of the first top plate 122 and the upper surface of the second top plate 142, and the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, at this time, the flexible support 34 abuts against the first top plate 122 of the first portion 12, that is, the flexible support 34 fills the 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 up and down, the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, and therefore, the thickness of the flexible supporting member 34 is equal to the thickness of the second top plate 142, and 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, can be filled, so that the flexible display screen 32 can be kept flat during movement, and thus, the phenomenon that the flexible display screen 32 collapses when touched when the electronic device 100 is in the expansion mode is avoided, and the operation experience of a user is improved.

In this embodiment, the flexible support 34 may be made of a magnetic material, the first top plate 122 may be made of a metal material capable of being magnetized or the first top plate 122 may include a metal layer capable of being magnetized coated on a surface thereof. In this way, the flexible support 34 may be attracted to the first top panel 122 as the second portion 14 moves away from the first portion 12 to expand the display portion 301 of the flexible display screen assembly 30. This prevents the flexible display assembly 30 from being misplaced or shifted during operation.

Referring to fig. 4 and fig. 6 to 8, in the present embodiment, the camera 60 may be disposed in the space of the accommodating chamber 140 of the second portion 14, and the camera 60 may be fixedly connected with the second portion 14 and collect images through the second portion 14. Specifically, camera 60 may perform image acquisition through floor 146 of second portion 14. That is, light can pass through the bottom plate 146 of the second portion 14 to be received by the camera 60 so that the camera 60 can perform image capturing through the second portion 60, and the camera 60 will also follow the second portion 14 when 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 a user can take a photograph conveniently in any situation. Of course, it should be understood that the camera 60 may be only partially located in the accommodating chamber 140, so long as the camera 60 can perform normal shooting and photographing functions, which is not limited herein.

Further, in order to enable the camera 60 to photograph and shoot normally, the bottom plate 146 may be provided with a through hole corresponding to the camera 60 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 collects an image through the light-transmitting area, that is, light may pass through the through hole or pass through 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 seals 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 collect 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 connection part 52 is detachably connected to the first portion 12, so that it is convenient to detach the first connection part 52 to repair and replace the main board 101, the battery, the sensor, or other electrical components stacked in the accommodating space 120. It will be appreciated that in other embodiments, the first connecting portion 52 and the first portion 12 may be integrally formed, and the specific arrangement 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 are corresponding 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, i.e. the first portion 12 and the second portion 14 move toward each other to the extreme position, the first connecting portion 52 and the second connecting portion 54 are spliced to form the cover 50 of the electronic device 100 together. Referring to fig. 8, the second connecting portion 54 is separated from the second connecting portion 54 when the second portion 14 moves away from the first portion 12.

Specifically, referring to fig. 7 and 8, in such an embodiment, the first connecting portion 52 is formed with an arc-shaped recess 542, the second connecting portion 54 is formed with a protrusion 522 matching the recess 542, and the protrusion 522 is also arc-shaped, when the electronic device 100 is in the narrow screen mode (as shown in fig. 7), the recess 542 and the protrusion 522 are spliced together to achieve the 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 may be made into other shapes, for example, both may be rectangular, and both may be directly spliced into the cover 50, for example, one of the two may be formed with regularly arranged protrusions, and the other may be formed with grooves corresponding to the protrusions, so that the shape of the housing 10 may be enriched to enhance the aesthetic feeling when the electronic device 100 is in the extended mode.

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

Referring to fig. 9, the restoring mechanism 40 may also be disposed in the accommodating space 120, the restoring mechanism 40 is connected to the reel 20, and the restoring mechanism 40 is used for applying a restoring force to the flexible display assembly 30 to keep the flexible display assembly 30 in a tendency to be rolled up on the reel 20.

Specifically, the return mechanism 40 applies a return force to the spool 20, and the spool 20 maintains the tendency of the flexible display assembly 30 to roll up on the spool 20 under the force of the return force. That is, when the second portion 14 is not moved relative to the first portion 12 by the external force, the restoring force of the restoring mechanism 40 rotates the reel 20, so that the end of the flexible display assembly 30 is wound on the reel 20, in which case the first portion 12 and the second portion 14 are completely engaged, and the 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 reel 20 to rotate against the restoring force to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display 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 elastic element may be a spring, such as a torsion spring as shown in fig. 9, or the like. Of course, the elastic element may be an element having elastic restoring force such as rubber, and is not limited herein.

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

Specifically, referring to fig. 10, in the present embodiment, the latch structure 80 may include a latch 82 formed on the first portion 12 and a latch 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 latch 82 is engaged in the latch 84. Thus, even if the external force to the second portion 14 is removed, 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 latch slot 84. To ensure that the electronic device 100 is in the expanded 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 second portion moves away from the first portion to the limit position, or may be any position before the limit position.

It will be appreciated that referring to fig. 11, in other embodiments, the first portion 12 may have a slot 84 and the second portion 14 may have a latch 82. In addition, in some embodiments, a latch may be formed on the first portion 12, a slot is formed on the reel 20, and when the second portion 14 moves to the preset position, the latch is engaged with the slot, in which case the latch may be manually pressed or electrically driven to engage the latch with the slot, so that the reel will not rotate relative to the first portion, and the second portion 14 and the flexible display screen assembly 30 will not retract under the action of the restoring mechanism 40. Of course, in other embodiments, the detent structure 80 may also include a catch, and the return mechanism 40 includes a torsion spring, which the catch may catch when the second portion 14 moves to the predetermined position to counteract the return force of the torsion spring. Additionally, it will be appreciated that in some embodiments, the detent structure 80 may also include a resilient assembly disposed on the first portion 12 and a first catch formed on the second portion 14, the resilient assembly may include a pressing member mounted on the first portion 12, a spring connecting the pressing member and the second catch, and a second catch formed on the second portion 14, the pressing member being operable to move the second catch under the force of an external force through the spring to engage the first catch, thereby defining the relative positions of the first portion 12 and the second portion 14. Thus, when the second portion 14 moves to the preset position, the user can press the pressing member to make the first fastening portion and the second fastening portion fasten, so as to prevent the second portion 14 from retracting under the action of the restoring force of the restoring mechanism 40, and keep the electronic device 100 in the extended mode. It will be appreciated that upon re-pressing the press, the first and second catch portions disengage, thereby enabling the second portion 14 and the flexible display assembly 30 to retract under the influence of the return mechanism 40 to return the electronic device 100 from the expanded mode to the narrow screen mode.

Referring to fig. 4 and 6, in the present embodiment, the driving mechanism 70 may be disposed in the accommodating space 120, where the driving mechanism 70 is connected to the second portion 14, and the driving mechanism 70 is used for driving the second portion 14 to perform a separation motion relative to the first portion 12 to drive the flexible display assembly 30 to move against the restoring force of the restoring mechanism 40, so as to expand the display portion 301 of the flexible display 32.

Specifically, the drive mechanism 70 may include a motor (not shown) that may be fixedly disposed within the receiving space 120 of the first portion 12 and a transmission structure 72 that is coupled to the motor and the second portion 14.

The drive structure 72 includes a drive gear 722 and a rack portion 724. The drive gear 722 is coupled to the motor, and the rack portion 724 is fixedly coupled to the second portion 14, with the rack portion 724 meshing 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. It will be appreciated that in other embodiments, the rack portion 724 may be formed separately from the second portion 14 and then fixedly attached thereto by welding or the like, but is not limited thereto.

In this embodiment, a motor may be used to drive the movement of the second portion 14 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 screen assembly 30 needs to be expanded, the motor drives the driving gear 722 to rotate, and the driving gear 722 drives the second portion 14 to perform a separation motion relative to the first portion 12 through the rack portion 724, so that the second portion 14 drives one end of the flexible display screen assembly 30 to move, thereby overcoming the restoring force of the restoring mechanism 40 to rotate the reel 20 to release the flexible display screen assembly 30, and further achieving the purpose of expanding the display portion 301 of the flexible display screen assembly 30. It will be appreciated that in this embodiment, the force applied by the motor to the second portion 14 through the transmission structure 72 can separate the latch 82 of the first portion 12 from the latch 84 of the second portion 14, and the restoring force of the restoring mechanism 40 does not cause the latch 82 to separate from the latch 84.

When the display portion 301 of the flexible display assembly 30 needs to be reduced, only the motor needs to be reversed to drive the second portion 14 to move in opposite directions relative to the first portion 12, in which case the second portion 14 gradually releases the flexible display assembly 30, i.e., the second portion 14 does not apply a force to the flexible display assembly 30, so that the reel 20 is reversed under the restoring force of the restoring mechanism 40, thereby gradually winding up the flexible display assembly 30, and thus keeping the winding and unwinding balance of the flexible display assembly 30.

It will be appreciated that when the display portion 301 needs to be reduced, the motor may be turned on only for a short period of time, so long as the latch 82 and the slot 84 are separated, and then the motor may not be started, the flexible display assembly 30 will be rolled up on the roller 20 under the restoring force of the restoring mechanism 40, and the second portion 14 will also move relatively to the first portion 12 under the restoring force. In such a case, the transmission gear 722 is in an automatic rotation state, and the speed of the second part 14 moving towards each other relative to the first part 12 under the action of the restoring force is not too high due to the transmission gear 722 and the rack portion 724, so that the second part 14 can be prevented from moving too fast to cause heavy collision with the first part 12.

Further, it will be appreciated that in this embodiment, the travel of the second portion 14 is equal to the length of the flexible display assembly 30 released by the rotation of the spool 20 per unit time. That is, by pulling one end of the flexible display assembly 30 at the second portion 14 by a certain distance, the roller 20 rotates to release a certain length, so that smooth movement of the flexible display assembly 30 can be ensured without wrinkling.

Furthermore, it is also understood that in some embodiments, in order to ensure the smoothness of the winding and releasing of the flexible display screen assembly 30 by the winding shaft 20, the number of driving mechanisms 70 may be two, and the number of winding shafts 20 may 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 connected to the second portions 14, respectively. In this way, smooth movement of the second portion 14 can be achieved by simultaneous actuation of two identical actuation mechanisms 70, thereby ensuring reliability of movement of the electronic device 100 when expanding the display portion 301 of the flexible display screen assembly 30.

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

Referring to fig. 3 to 6, as described above, the electronic device 100 can switch between the narrow-screen mode and the extended mode. In the state shown in fig. 3 and 4, the electronic device 100 is in the narrow screen mode, and in the state shown in fig. 5 and 6, the electronic device 100 is in the expansion mode. When in the narrow screen mode, the first portion 12 and the second portion 14 cooperate to form the housing 10, one end of the flexible display screen assembly 30 is wound on the spool 20, and the other end is connected to the second portion 14, at this time, only a smaller portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrower, which is convenient for a user to carry.

When a user needs a larger display portion 301, the second portion 14 can be driven by the driving mechanism 70 to make a separation movement relative to the first portion 12, at this time, the second portion 14 drives the flexible display screen assembly 30 to stretch 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 be convenient for the user to operate to improve the operation experience of the user.

When the expansion mode is required to be switched to the narrow screen mode, the motor of the driving mechanism 70 is required to be reversed to drive the second portion 14 to move relatively to the first portion 12, so that the flexible display screen assembly 30 is released, at this time, the reel 20 correspondingly reverses under the action of the restoring force of the restoring mechanism 40, the flexible display screen assembly 30 is synchronously and stably rolled up, when the motor 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 according to the embodiment of the present application includes the housing 10, the reel 20, the flexible display assembly 30, and the restoring mechanism 40. The housing 10 comprises a first part 11 and a second part 13 which are relatively movable. The spool 20 is rotatably disposed in the first portion 11. One end of the flexible display assembly 30 is attached to the second portion 13 and the other end is provided on the spool 20. Wherein upon a separation movement of the first portion 11 and the second portion 13, the spool 20 can be rotated 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 spool 20, the return mechanism 40 being configured to apply a return force to the flexible display assembly 30 to maintain the flexible display assembly 30 in a tendency to roll up on the spool 20.

In summary, in the electronic device 100 according to the embodiment of the application, the restoring mechanism 40 is connected to the reel 20, and the restoring mechanism 40 can apply a restoring force to the flexible display assembly 30 to keep the flexible display assembly 30 in a tendency to be rolled up on the reel 20. When the second portion 14 moves away from the first portion 12 under the action of an external force, the reel 20 needs to overcome the restoring force of the restoring mechanism 40 to rotate to release the flexible display screen assembly 30, so that the restoring mechanism 40 can continuously apply a force to the reel 20 in the expanding process of the flexible display screen assembly 20, thereby ensuring that the flexible display screen assembly 30 keeps stable during movement, and meanwhile, the existence of the restoring force can also enable the display portion 30 of the flexible display screen assembly 30 to keep flat, so that the flexible display screen assembly 30 is prevented from wrinkling.
