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 second portion 14 is movable between a first position a and a second position B, and 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 between the first position a and the second position B.

Referring to fig. 3 to 7, in an embodiment, the first portion 12 may be substantially rectangular, the first portion 12 forms a receiving space 120, and a bottom of the receiving space 120 is open. 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.

Referring to fig. 3 and 8, the first portion 12 includes a first top plate 122 and a first side plate 123, the first side plate 123 and the first top plate 122 jointly define the accommodating space 120, the first top plate 122 is opened with a first opening 1222 and a second opening 1224, and the first opening 1222 and the second opening 1224 are both communicated with 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 number of the first side plates 123 is two, and the two first side plates 123 are connected to both longitudinal sides of the first top plate 122 and are substantially symmetrically arranged.

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 disposed on the first portion 12, the second portion 14 may also be substantially rectangular, and the second portion 14 includes a second top plate 142 and a second side plate 144. The second side panels 144 are connected to both longitudinal sides of the second top panel 142 and are substantially symmetrically disposed. The second side plate 144 is adapted to cooperate with the slide channel 124 of the first portion 12 to slidably couple the first portion 12 to the second portion 14, and the second top plate 142 abuts 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, i.e. from the first position a to the second position B. In addition, in the present embodiment, the first portion 12 and the second portion 14 can also move towards each other, and the movement of the two towards each other can be understood as the second portion 14 sliding relative to the first portion 12 and moving towards the first portion 12 in the sliding direction, i.e. from the second position B to the first position a.

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 second portion 14 is located at the first position a, and 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, when the first portion 12 and the second portion 14 move away from each other (i.e. they move away from each other), the second portion 14 is away from the first portion 12, and when they move away to the extreme position, the second portion 14 is located at the second position B, that is, in the present embodiment, the second portion 14 can move between the first position a and the second position B relative to the first portion 12. It should be noted that in this context, movement of the second portion 14 away from the first portion 12 is understood to mean movement of the second portion 14 from the first position a to the second position B, and movement of the second portion 14 towards the first portion 12 is understood to mean movement of the second portion 14 from the second position B to the first position a.

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 screen assembly 30 is fixedly connected to the second portion 14, and the other end is wound around the winding shaft 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 second portion 14 away from the first portion 12, i.e. movement of the second portion 14 from the first position a to the second position B, the spool 20 is able to rotate to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display 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 second portion 14 away from the first portion 12, i.e., movement of the second portion 14 from the first position a to the second position B, the spool 20 can rotate to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display 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. 5, in one instance, the first portion 12 and the second portion 14 are connected together in close proximity, i.e., the second portion 14 is in the first position a, 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 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 plate 122 and exposed from the housing 10 for display. 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 for display.

Referring to fig. 7, when the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the second portion 14 moves away from the first portion 12, that is, the second portion 14 moves from the first position a to the second position B, 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 when the second portion 14 is in the second position B, 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 for display is the largest, i.e., the display portion 301 of the flexible display screen assembly 30 is the largest in area (as shown in fig. 7). When the first portion 12 and the second portion 14 are closely and jointly fitted together, i.e., the second portion 14 is located in the first position a, the display area of the electronic device 100 is the smallest, i.e., the display portion 301 of the flexible display screen assembly 30 is the smallest 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 another medium. 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 member 34 is large, so that the phenomenon that the flexible display screen 32 is deformed by pressing and the like can be reduced.

In this way, when the electronic device 100 is in the narrow-screen mode (i.e. when the second portion 14 is located at the first position a), only the flexible supporting member 34 is wound up by the reel 20, and the flexible display screen 32 is not directly wound up by the reel 20, so that the degree and number of times of bending of the flexible display screen 32 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 support 34 completely covers the second region 324, and the supporting area of the flexible support 34 is large, 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 electric components such as the main board 101, the sub-board 103, the sensor, and the battery 102 of the electronic device 100 can be accommodated in a 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 second portion 14 moves away from the first portion 12, 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, in this embodiment, 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 can be understood that, referring to fig. 7, when the second portion 14 moves away from the first portion 12, i.e. moves from the first position a to the second position B, 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, 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 supports against the first top plate 122 of the first portion 12, i.e. the flexible supporting member 34 fills the gap between the flexible display screen 32 and the first top plate 122. That is to say, 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 can be filled, 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 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 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. 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.

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 capturing.

Referring to fig. 13 and 15, 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. 14 and 16, when the second portion 14 moves away from the first portion 12 and the second portion 14 moves from the first position a to the second position B, the second connecting portion 54 is separated from the second connecting portion 52.

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. 3, fig. 5 and fig. 7, in the present embodiment, the driving mechanism 70 may be disposed in the accommodating space 120 of the first portion 12, 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 extend.

In addition, referring to fig. 5 and 7, in an embodiment, the driving mechanism 70 may be further connected to the roller 20, and when the driving mechanism 70 drives the second portion 14 to move away from the first portion 12 (from the first position a to the second position B), the driving mechanism 70 may also drive the roller 20 to rotate to release the flexible display assembly 30, so as to expand the display portion 301 of the flexible display assembly 30.

Specifically, the driving mechanism 70 may include a motor 71, a first transmission structure 72 and a second transmission structure 74, and the motor 71 may be fixedly disposed in the accommodating space 120 of the first portion 12. The first transmission structure 72 is connected with the second part 14 and the motor 71, the second transmission structure 74 is connected with the first transmission structure 74 and the reel 20, and the motor 71 is used for driving the second part 14 to move relative to the first part 12 through the first transmission structure 72 and driving the reel 20 to rotate through the first transmission structure 72 and the second transmission structure 74.

The first transmission 72 includes a first transmission gear 722 and a rack 724. The first transmission gear 722 is connected with the second transmission structure 74 and fixed on the motor shaft 711 of the motor 71, the rack 724 is fixedly connected with the second portion 14, and the rack 724 is meshed with the first transmission gear 722. Therefore, the gear and the rack are adopted for driving in the embodiment, the structure is simple, and the transmission is stable and reliable.

Specifically, in the present embodiment, the rack 724 is integrally formed with the second top plate 142 of the second portion 14, that is, the rack 724 may be directly and integrally formed on the lower surface of the second top plate 142, so that the rack 724 may be directly machined on the second top plate 142, and the integrity is good and the machining is convenient. It is understood that in other embodiments, the rack 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.

Referring again to fig. 5 and 7, the second transmission structure 74 connects the spool 20 and the first transmission gear 722. The second transmission structure 74 includes a second transmission gear 742 and a third transmission gear 744, the second transmission gear 742 is fixed on the winding shaft 20 and is concentrically arranged with the winding shaft 20, the third transmission gear 744 is rotatably arranged on the first portion 12, and the third transmission gear 744 connects the second transmission gear 742 and the first transmission gear 722, i.e. the third transmission gear 744 is respectively meshed with the second transmission gear 742 and the first transmission gear 722, and the first transmission gear 722 and the second transmission gear 742 are located on two opposite sides of the third transmission gear 744.

In this embodiment, the motor 71 may be used to drive the second portion 14 in motion relative to the first portion 12 via the first transmission structure 72. At the same time, the motor 71 can also be used to drive the second portion 14 to move away from the first portion 12, and simultaneously drive the reel 20 to rotate through the second transmission structure 74 to release the flexible display screen assembly 30. In this manner, the stretching of the flexible display assembly 30 and the synchronized release of the roller 20 results in a smoother motion and less tendency for the flexible display assembly 30 to wrinkle.

Specifically, when the display area of the electronic device 100 needs to be expanded, that is, the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the motor 71 drives the first transmission gear 722 to rotate, the first transmission gear 722 drives the second portion 14 to move away from the first portion 12 through the rack 724, that is, to move from the first position a to the second position B, the second portion 14 drives the flexible display screen assembly 30 to extend, that is, drives one end of the flexible display screen assembly 30 to move away from the first portion 12, meanwhile, the first transmission gear 722 also drives the third transmission gear 744 to rotate, and the third transmission gear 744 drives the scroll 20 to rotate, so that the scroll 20 can synchronously release the flexible display screen assembly 30, and the purpose of expanding the display portion 301 of the flexible display screen assembly 30 is achieved.

It will be appreciated that when the display portion 301 of the flexible display screen assembly 30 needs to be reduced, i.e. the second position B moves from the first position a, the motor 71 need only be reversed to drive the second portion 14 to move towards the first portion 12, in which case the second portion 14 gradually releases the flexible display screen assembly 30 and the reel 20 can also gradually roll up the flexible display screen assembly 30. 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 assembly 30 released by the rotation of the spool 20. That is, the spool 20 rotates to release the length of the flexible display assembly 30 by the amount of distance the end of the flexible display assembly 30 is pulled by the second portion 14, thus ensuring smooth movement of the flexible display assembly 30 without wrinkling.

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 driving mechanisms 70 may be two, and the number of the winding shafts 20 is also 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 and also respectively connected to the two winding shafts 20. In this way, the two reels 20 can be synchronously and smoothly rotated and the second portion 14 can be smoothly moved by the synchronous driving of the two identical driving mechanisms 70, 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.

Furthermore, in other embodiments, the driving mechanism 70 may also include two synchronous motors 71 disposed on the first portion 12, wherein one motor 71 is used to drive the second portion 14 relative to the first portion 12, and the other motor 71 is used to drive the spool 20, and both motors 71 are used to drive the spool. In this way, the two motors 71 move synchronously, and the smoothness of movement and the reliability of movement of the flexible display screen assembly 30 can also be ensured.

Further, in the present embodiment, the driving mechanism 70 drives the second portion 14 and the spool 20 by means of a gear transmission and a rack-and-pinion transmission. It is understood that in other embodiments, the driving mechanism 70 may drive the second portion 14 and the spool 20 by a combination of belt transmission and rack-and-pinion transmission or a combination of chain transmission and rack-and-pinion transmission, for example, the first transmission structure 72 may be a rack-and-pinion transmission, and the second transmission structure 74 may be a belt transmission or a chain transmission, which is not limited herein.

In addition, in some embodiments, the driving mechanism 70 may include only a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, and the motor may drive the second portion 14 to move relative to the first portion 12 via the first transmission structure 72. In addition, the electronic device 100 may further include a restoring structure (not shown) connected to the roller 20, the restoring structure being configured to apply a force to the flexible display assembly 30 via the roller 20 to maintain the flexible display 32 in a rolled orientation on the roller 20.

In addition, referring to fig. 17, in some embodiments, the driving mechanism 70 may also include a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, the motor may drive the second portion 14 to move relative to the first portion 12 through the first transmission structure 72, and the second transmission structure 74 may be omitted.

Further, referring to fig. 17 to fig. 20, in this embodiment, the electronic device 100 may further include a restoring mechanism 80, the restoring mechanism 80 may also be disposed in the accommodating space 120, the restoring mechanism 80 is connected to the first reel 20, and the restoring mechanism 20 is configured to apply a restoring force to the flexible display screen assembly 30 so as to keep the flexible display screen assembly 30 tending to be wound on the first reel 20.

Specifically, the return mechanism 80 applies a return force to the first spool 20, and the first spool 20 maintains the tendency of the flexible display screen assembly 30 to roll up on the first spool 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 80 may cause first roller 20 to rotate, thereby causing one end of flexible display screen assembly 30 to be wound onto first roller 20, in which case first portion 12 and second portion 14 are fully mated together 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 (e.g., the force applied to the second portion 14 by the driving mechanism 70) is greater than or equal to the restoring force of the restoring mechanism 80, the second portion 14 moves away from the first portion 12, i.e., from the first position a to the second position B, thereby rotating the first roller 20 against the restoring force to release the flexible display assembly 30, and thus expanding the display portion 301 of the flexible display assembly 30.

It will be appreciated that due to the presence of the return mechanism 80, the return mechanism 80 will always apply tension to the flexible display assembly 30 during expansion of the display portion 301 of the display layer 32, thereby allowing the flexible display to be extended and retracted in equilibrium, i.e., keeping the flexible display assembly 30 flat at all times.

It will also be appreciated that in other embodiments, where the electronic device 100 includes the return mechanism 80, the driving mechanism 70 may also include the motor, the first transmission structure 72 and the second transmission structure 74 in the above embodiments, the first transmission structure 72 is connected to the second portion 12 of the motor, and the second transmission structure 74 is connected to the first transmission structure 72 and the first reel 20. In such an embodiment, when the display area 301 needs to be reduced, the motor may not be operated, and the restoring force of the restoring mechanism 80 is used to rotate the first roller 20 reversely to roll up the flexible display screen assembly 30 and move the second portion 14 relative to the first portion 12 in the opposite direction, i.e. close to the first portion 12.

Further, referring to fig. 18, the restoring mechanism 80 may include an elastic element connected to the first reel 20 and configured to apply a restoring force to the first reel 20. The resilient member may be a spring, such as a torsion spring as shown in fig. 18. Of course, the elastic element may also be an element having elastic restoring force, such as rubber, and is not limited herein.

Further, referring to fig. 19, in such an embodiment, the electronic device 100 may further include a detent structure 90, the detent structure 90 is disposed on the housing 10, and the detent structure 90 is used for limiting the rotation of the first reel 20 when the second portion 14 moves to a predetermined position relative to the first portion 12. That is, detent structure 90 prevents retraction of second portion 14 and flexible display screen assembly 30 under the restoring force of restoring mechanism 80 when second portion 14 is moved to a predetermined position relative to first portion 12.

Specifically, referring to fig. 19, in the present embodiment, the locking structure 90 may include a locking block 92 formed on the first portion 12 and a locking groove 94 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 92 is locked in the locking groove 94. Thus, even if the external force is removed from second portion 14, second portion 14 and flexible display assembly 30 will not retract under the restoring force of restoring mechanism 80 due to the engagement of latch 92 with latch slot 94. 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 should be understood that referring to fig. 20, in other embodiments, a slot 94 may be formed in the first portion 12 and a latch 92 may be formed in the second portion 14. In addition, in some embodiments, a latch may be formed on the first portion 12, a slot is formed on the first reel 20, and the latch and the slot are engaged when the second portion 14 moves to the predetermined position, in which case, the latch and the slot may be engaged by a manual pressing manner or an electric driving manner, so that the reel does not rotate relative to the first portion, and the second portion 14 and the flexible display screen assembly 30 do not retract under the action of the restoring mechanism 80. Of course, in other embodiments, the detent structure 90 can also include a detent, and the return mechanism 80 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 is also understood that, in some embodiments, the detent structure 90 may also include an elastic component disposed on the first portion 12 and a first latching portion formed on the second portion 14, the elastic component may include a pressing piece, a spring and a second latching portion, the pressing piece is mounted on the first portion 12, the spring connects the pressing piece and the second latching portion, and the pressing piece may be used to drive the second latching portion to move to latch with the first latching portion under the action of 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 80, and the electronic device 100 is kept in the extended mode. It will be appreciated that when the pressing member is pressed again, the first catch portion and the second catch portion are disengaged, thereby enabling the second portion 14 and the flexible display assembly 30 to be retracted under the action of the return mechanism 80 to return the electronic device 100 from the extended mode to the narrow screen mode.

The electronic device 100 of the present embodiment operates as follows:

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 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 being convenient for the user to carry.

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, at this time, the second portion 14 drives one end of the flexible display screen 32 to move, and at the same time, the driving mechanism 70 also drives the reel 20 to rotate and release the flexible display screen assembly 30, so that the part 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 motor 71 of the driving mechanism 70 is only required to be rotated reversely to drive the second portion 14 to move oppositely relative to the first portion 12, so as to release the flexible display screen assembly 30, at this time, the reel 20 is also rotated reversely correspondingly to synchronously wind the flexible display screen assembly 30, 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 71 stops running, and the electronic device 100 returns to the narrow-screen mode.

Referring to fig. 21 to 24, in some embodiments of the present application, when the second portion 14 is located at the second position B, the cavity 110 is exposed from the housing 10, and the cavity 110 is used for the external functional device 200 to be inserted so as to connect the external functional device 200 with the electronic device 100.

In such an embodiment, when the second portion 14 moves from the first position a to the second position B, the second portion 14 brings the flexible display screen assembly 30 to stretch to expand the display portion 301 of the flexible display screen assembly 30, and meanwhile, when the second portion 14 is located at the second position B, the housing 10 exposes the cavity 110, so that the cavity 110 can accommodate the external functional assembly 200. In this way, after the display portion 301 of the flexible display screen assembly 30 is expanded, the user can put the external functional assembly 200 into the cavity 110 to connect with the electronic device 100, so as to improve the usability of the electronic device 100 and improve the user experience, for example, an external battery assembly can be put into the cavity 110 to improve the cruising ability of the electronic device 100.

In some embodiments, the external functional component 200 includes at least one of an external battery component, a speaker component, a key component, a light component, and a camera component.

In this way, the external battery assembly, the speaker assembly, the key assembly, the light assembly and the camera assembly can be inserted into the cavity 110 to improve the performance of the electronic device 100.

Specifically, referring to fig. 22 and 23, when the second portion 14 is located at the second position B, the electronic device 100 is in the extended mode, at this time, the area of the display portion 301 of the flexible display screen assembly 30 is the largest, so that the power consumption of the electronic device 100 is increased, and when the external functional assembly 200 is an external battery assembly, the external battery assembly can serve as an external power source of the electronic device 100, so as to improve the cruising ability of the electronic device 100. In addition, when the second portion 14 is located at the second position B, the volume of the electronic device 100 is also maximized, and at this time, the audio frequency of the electronic device 100 is still the original self-contained audio frequency, and the sound cavity is too small compared with the expanded volume of the electronic device 100, so that a better stereo effect cannot be brought. Under the condition, the loudspeaker assembly is placed in the cavity 110, so that the sound cavity experience of the whole machine can be improved, the larger and better 3D surround sound experience is brought, and the user experience is improved. In addition, when the second portion 14 is located at the second position B, the electronic device 100 has a large volume, which may cause inconvenience for the user to use the key, in such a case, the key assembly can be placed in the cavity 110, and the key assembly can provide more operation space for the electronic device 100, so that the user can better operate the electronic device 100. In addition, when the external functional component 200 is a light component, the light component may enable the electronic device 100 to exhibit different light effects, so as to improve the diversity of the user usage, and when the external functional component 200 is a camera component, the camera component may be an electronic device having more cameras to increase the photographing function of the electronic device 100 and improve the photographing performance. Herein, the description will be mainly given taking as an example that the external functional module 200 is a battery module and a speaker module.

In addition, in the embodiment shown in fig. 21, the number of the cavities 110 is two, and two cavities 110 are located on two opposite sides of the electronic device 100. It will be appreciated that the two cavities 110 may house the same or different external functional components, for example, one for housing an external battery component and the other for housing a speaker component, again without limitation.

Referring to fig. 21-24, in some embodiments, second portion 14 includes a second side plate 144, and when second portion 14 is in second position B, second side plate 144 is spaced apart from first portion 12 and cooperates with first portion 12 to define cavity 110.

Thus, when the second portion 14 is in the second position B, the second side plate 144 is spaced apart from the first portion 12 to define the cavity 110, and the external functional component 200 can be placed in the cavity 110 to connect with the electronic device 100.

Specifically, referring to fig. 21, in such an embodiment, when second portion 14 is located at first position a, second side plate 144 may abut against first portion 12 or be spaced closer to first portion 12, and when second portion 14 moves from first position a to second position B (from the state of fig. 21 to the state of fig. 22), second side plate 144 gradually moves away from first portion 12 to gradually form cavity 110 spaced from first portion 12.

In such embodiments, the second portion 14 can also include a bottom panel 146, in which case the bottom panel 146 can also be slidably coupled to the first portion 12, it being understood that in some embodiments, the second portion 14 can be slidably coupled to the first portion 12 via the bottom panel 146, or slidably coupled to the first portion 12 via the second side panel 144 and the bottom panel 146.
