Referring to fig. 6 and 8, in the present embodiment, the phrase "the first portion 11 moves away from the third portion 15" can be understood as that the first portion 11 is away from one side of the third portion 15 and the sliding direction is away from the third portion 15, and at this time, the second portion 13 can also be away from the other side of the third portion 15 and the sliding direction is away from the third portion 15 or is stationary relative to the third portion 15. By "the second part 13 moves away from the third part 15" it is understood that the second part 13 is away from the third part 15 and slides away from the third part 15, in which case the first part 11 may also be away from the other side of the third part 15 and slides away from the third part 15 or is stationary relative to the third part 15. That is, or, in the present application, the first portion 11 and the second portion 13 can both move away from each other, either individually or simultaneously, relative to the third portion 15, thereby expanding the display portion of the screen assembly 30. In the present embodiment, the first portion 11 and the second portion 13 are mainly described as an example of moving away from each other relative to the third portion 15 at the same time, for example, moving from the state shown in fig. 5 and 6 to the state shown in fig. 7 and 8.

In addition, in the present embodiment, the first portion 11 and the second portion 13 may also move toward each other with respect to the third portion 15, and in this case, it can be understood that the first portion 11 and the second portion 13 respectively approach to both sides of the third portion 15 and slide toward the third portion 15, and for example, move from the state shown in fig. 7 and 8 to the state shown in fig. 5 and 6.

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. 17, in the present embodiment, when the first portion 11 and the second portion 13 move to the extreme positions relative to the third portion 15 (i.e. when the first portion 11 and the second portion 13 approach each other and the third portion 15 is engaged with each other), the first portion 11, the second portion 13, and the third portion 15 form a substantially rectangular housing 10, and the first portion 11 and the second portion 13 are partially accommodated in the third portion 15. Referring to fig. 19, when the first portion 11 and the second portion 13 move away from each other (i.e., move away from each other), the first portion 11 and the third portion 15 move away from each other, and the second portion 13 and the third portion 15 move away from each other, in such a case, the first portion 11 and the second portion 13 are also partially accommodated in the third portion 15 to be stably connected to the third portion 15.

Referring to fig. 6 and 8, in the present embodiment, the spool 20 includes a first spool 21 and a second spool 23. The first reel 21 is rotatably disposed in the first portion 11 and located in the first receiving space 110, that is, the first reel 21 may be installed in the first receiving space 110 and may rotate relative to the first portion 11. First roller 21 is attached to one end of flexible display screen assembly 30 for winding or releasing flexible display screen assembly 30.

The second reel 23 and the first reel 21 are substantially identical in structure, the second reel 23 and the first reel 21 are arranged centrally symmetrically with respect to the housing 10, and the second reel 23 is rotatably arranged in the second portion 13 and located in the second housing space 130, that is, the second reel 23 is mountable in the second housing space 130 and rotatable with respect to the second portion 13. The second roller 23 is connected to the other end of the flexible display screen assembly 30 for rolling up or releasing the flexible display screen assembly 30, that is, the first roller 21 and the second roller 23 are respectively connected to both ends of the flexible display screen assembly 30.

It is understood that the rotational arrangement of the first roller 21 on the first portion 11 may mean that the first roller 21 is directly mounted on the first portion 11, or that the first roller 21 is mounted on the first portion 11 by other media. The second reel 23 is rotatably disposed on the second portion 13, which means that the second reel 23 is directly mounted on the second portion 13, or that the second reel 23 is mounted on the second portion 13 through other medium.

With continued reference to fig. 6 and 8, the two ends of the flexible display screen assembly 30 are respectively wound around the first reel 21 and the second reel 23. Specifically, one end of the flexible display screen assembly 30 is wound around the first roller 21 through the first opening 1111 of the first portion 11, and the other end is wound around the second roller 23 through the second opening 1311 of the second portion 13. When the first portion 11 and the second portion 13 are moved apart, i.e. the first portion 11 and the second portion 13 are both moved away from the third portion 15, the first roller 21 and the second roller 23 can be simultaneously rotated to gradually release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. The flexible display panel assembly 30 is also symmetrically disposed about the center of the housing 10, that is, the portion of the flexible display panel assembly 30 wound around the first winding shaft 21 and the portion wound around the second winding shaft 23 are symmetrical.

In this manner, upon a movement of the first and

second portions

11, 13 away from each other, the first and

second spools

21, 23 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. Meanwhile, two reels are arranged to roll up and release two ends of the flexible display screen assembly 30 respectively, so that stress at two ends of the flexible display screen assembly is smaller in the reel rotating process, and the unfolding process is more stable.

It is to be understood that in this embodiment, in a case where the first portion 11, the second portion 13, and the third portion 15 are close and completely fitted, in such a case, the display portion 301 of the flexible display screen assembly 30 is not expanded, and the electronic device 100 is in a narrow screen mode (for example, the state shown in fig. 5 and 6), in which one end of the flexible display screen assembly 30 is wound on the first reel 21 and the other end is wound on the second reel 23, and a portion exposed from the housing 10 (i.e., the display portion 301) is used for display.

When it is desired to expand the display portion 301 of the flexible display assembly 30, the first portion 11 and the second portion 13 move away from each other, such that the first portion 11 and the second portion 13 are away from each other, the first roller 21 and the second roller 23 are also away from each other, and since the two ends of the flexible display assembly 30 are respectively connected to the first roller 21 and the second roller 23, during the process of the moving away, the first roller 21 and the second roller 23 rotate simultaneously to release the two ends of the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30, in which case the electronic device 100 is in the expansion mode (e.g., the state shown in fig. 7 and 8).

It will be appreciated that the movement of the second and

first portions

13, 11 away from each other presents an extreme position, i.e. an extreme position in which they are away from the third portion 15, in which the display area of the electronic device 100, i.e. the display portion 301 of the flexible display screen assembly 30, is at a maximum (see fig. 3). When the first, second and

third portions

11, 13, 15 are brought together closely and fully, the display area of the electronic device 100, i.e., the display portion 301 of the flexible display screen assembly 30, is minimized (see fig. 1).

Note that, in this embodiment, the "display portion 301 of the flexible display panel assembly 30" may also be understood as a portion exposed from the housing 10, that is, a portion outlined by a dashed box in fig. 6 and 8.

Specifically, referring to fig. 6 and 8, in the present embodiment, the flexible display panel assembly 30 includes a flexible display panel 31 and a flexible supporting member 33, and the flexible display panel 31 and the flexible supporting member 33 are stacked and fixedly connected.

The flexible display screen 31 includes a first region 311 and second and

third regions

313 and 315 connected to both ends of the first region 311, and the first region 311 is positioned above the first and second

top plates

111 and 131 and has substantially the same size as the first and second

top plates

111 and 131. The second region 313 is at least partially located within the first receiving space 110 of the first portion 11 and is connected with the flexible support 33.

The third region 315 is at least partially located within the second receiving space 130 of the second portion 13 and is connected with the flexible support 33. In the present embodiment, extending the display portion 301 of the flexible display panel assembly 30 may be understood as pulling out the second region 313 located in the first receiving space 110 or the third region 315 located in the second receiving space 130 or pulling out both at the same time to be exposed from above the housing 10, so as to extend the display portion 301 of the flexible display panel assembly 30 for displaying, i.e. to extend the display area of the electronic device 100.

The flexible support 33 is disposed at the bottom of the flexible display screen 31 and covers the lower surface of the flexible display screen 31. The flexible support 33 may be fixedly connected to the flexible display screen 31 by an Optical Clear Adhesive (OCA). In the example shown in fig. 6 and 8, the flexible support 33 includes a first support portion 332, a second support portion 333, and a third support portion 334, the second support portion 333 and the third support portion 334 are respectively connected to both ends of the first support portion 332, the first support portion 332 corresponds to the flexible display screen 31, the second support portion 333 is wound around the first reel 21, the third support portion 334 is wound around the second reel 23, that is, both ends of the flexible support 34 extend beyond the flexible display screen 31, and the extending portions are respectively connected to the first reel 21 and the second reel 23.

Referring to fig. 6, when the electronic device 100 is in the narrow-screen mode, two ends of the flexible supporting member 33 are respectively connected to the first reel 21 and the second reel 23 and are respectively wound around the first reel 21 and the second reel 23, the flexible display screen 31 is substantially in a racetrack shape, and the main board 101, the sub-board, the sensors, the batteries and other electrical components of the electronic device 100 can be accommodated in a space surrounded by the flexible display screen assembly 30. Like this, the mode of setting up of flexible display screen subassembly 30 can not influence putting of electrical components such as mainboard 101 and battery, the effectual utilization ratio that improves the space is favorable to piling up and putting of electrical components such as mainboard 101, battery.

In addition, when the electronic device 100 is in the narrow screen mode, only the second support part 333 and the third support part 334 of the flexible support member 33 are wound up by the first reel 21 and the second reel 23, and the flexible display screen 31 is not directly wound up by the first reel 21 and the second reel 23, so that the service life of the flexible display screen 31 is prolonged. Of course, it is understood that in other embodiments, the flexible display screen 31 may be connected to the first reel 21 and the second reel 23 after completely corresponding to the flexible support member 33, that is, the flexible support member 33 corresponds to the flexible display screen 31, and the flexible support member 33 and the flexible display screen 31 are wound together on the first reel 21 and the second reel 23.

Referring to fig. 6 and 8, in the present embodiment, when the first portion 11 moves away from the third portion 15, the flexible supporting member 33 supports against the first portion 11 to keep the flexible display screen 31 flat. When the second portion 13 moves away from the third portion 15, the flexible supporting member 33 abuts against the second portion 13 to keep the flexible display screen 31 flat.

Like this, flexible support piece 33 can play the effect that increases flexible display screen 31's intensity, can guarantee that flexible display screen 31 can level and smooth and steady when the motion, also can prevent flexible display screen 31 and appear damaging under the effect of great effort simultaneously.

Specifically, in the present embodiment, when the first portion 11 and the third portion 15 are separated, a portion of the flexible support 33 is attached to the first top plate 111 of the first portion 11 to fill the gap between the flexible display screen 31 and the first top plate 111 and the flexible display screen 31. When the second portion 13 and the third portion 15 are separated, a portion of the flexible support 33 is attached to the second portion 13 and the second top plate 131 to fill a gap between the flexible display screen 31 and the second top plate 131.

In addition, with continued reference to fig. 5, 6 and 8, a first tooth 331 is formed at the bottom of the flexible supporting member 33, and specifically, in the illustrated embodiment, the first supporting portion 332, the second supporting portion 333 and the third supporting portion 334 are each formed with a first tooth 331, and the first tooth 331 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. It is understood that, in other embodiments, the first tooth 331 may not be provided on the first support portion 332, and the first tooth 331 may be provided on the second support portion 333 and the third support portion 334.

Can clean upSolution (II)In other embodiments, the rack portion 724 may be formed separately from the first top plate 111, and then the two may be fixedly connected together by welding or the like, which is not limited herein.

Referring again to fig. 6 and 8, 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, a motor may be used to drive the first section 11 relative to the third section 15 via the first transmission structure 72. At the same time, the motor may be used to drive the first portion 11 to move away from the third portion 15, and at the same time, the second transmission structure 74 may be used to drive the first roller 21 to rotate to release the flexible display screen assembly 30.

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 first transmission gear 722 can be driven by the motor to rotate, the first transmission gear 722 drives the first portion 11 to move away from the third portion 15 through the rack portion 724, at this time, the first reel 21 also moves along with the first portion 11 relative to the third portion 15, meanwhile, the first transmission gear 722 can also drive the third transmission gear 744 to rotate at the same time, the third transmission gear 744 drives the second transmission gear 742 to rotate, and then the first reel 21 is driven to rotate, so that the reel 20 can release the flexible display screen assembly 30 synchronously, and the purpose of expanding the display portion 301 of the flexible display screen assembly 30 is achieved.

It is understood that in the present embodiment, the specific structure of the second driving assembly 80 is the same as the specific structure of the first driving assembly 70, and the specific connection manner of the second driving assembly 80 and the second portion 13 is substantially the same as that of the first driving assembly 70 in the first portion 11, and therefore, in order to avoid redundancy, detailed description is omitted here.

In addition, when the flexible display panel 301 needs to be reduced, the motor of the first driving assembly 70 is only required to rotate reversely to drive the first portion 11 to move relative to the third portion 15, and in such a case, the first roller 21 is also rotated reversely by the driving mechanism to gradually roll up one end of the flexible display panel assembly 30 (for example, to move from the state shown in fig. 8 to the state shown in fig. 6).

It will be appreciated that in this embodiment, the travel of the first portion 11 per unit of time is equal to the length of the flexible display screen assembly 30 released by the rotation of the first roller 21. That is, by how much the first portion 11 moves, the first roller 21 rotates to release the length, which ensures that the flexible display screen assembly 30 can move smoothly without wrinkles.

Similarly, when the display area of the electronic device 100 needs to be expanded, the second driving assembly 80 disposed in the second receiving space 130 can also drive the second portion 13 to move away from the third portion 15 and the first portion 11, and at the same time, the second driving assembly 80 drives the second roller 23 to rotate, so that the second roller 23 can gradually release the flexible display panel assembly 30, thereby expanding the display portion 301 of the flexible display panel assembly 30.

It can be understood that, in this embodiment, when the display portion 301 of the flexible display panel assembly 30 needs to be expanded, one of the first driving assembly 70 and the second driving assembly 80 can be used alone to drive the first portion 11 or the second portion 13 to move away from the third portion 15, so as to achieve the purpose of expanding the flexible display panel assembly 30. Of course, the same purpose can be achieved by the first driving assembly 70 and the second driving assembly 80 simultaneously driving the first portion 11 and the second portion 13 to move away from each other relative to the third portion 15. Preferably, in this embodiment, the expansion of the display portion 301 of the flexible display screen assembly 30 is mainly achieved by using two driving mechanisms to synchronously drive the first portion 11 and the second portion 13 to move relative to the third portion 15. (e.g., moving from the state shown in FIG. 6 to the state shown in FIG. 8)

Next, the operation principle of the electronic device 100 according to the present embodiment will be described by using two driving mechanisms to simultaneously drive the first portion 11 and the second portion 13.

Referring to fig. 5 to 8, 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. 5 and 6, the electronic apparatus 100 is in the narrow screen mode, and in the state shown in fig. 7 and 8, the electronic apparatus 100 is in the extended mode. When in the narrow screen mode, first portion 11, second portion 13 and third portion 15 cooperate to form housing 10, and one end of flexible display screen assembly 30 is wound on first roller 21 and the other end is wound on second roller 23, at which time only a small portion of flexible display screen assembly 30 is exposed from housing 10, and display portion 301 is narrow, which is convenient for the user to carry.

When a user needs a larger display section 301, the first and

second sections

11 and 13 are driven to move away from each other relative to the third section 15 by the first and

second drive assemblies

70 and 80, respectively, and the moving directions of the first and

second sections

11 and 13 are opposite. At this time, the first driving assembly 70 and the second driving assembly 80 respectively drive the first roller 21 and the second shaft 23 to rotate to release the flexible display screen assembly 30, so that the second region 313 of the flexible display screen 31 hidden in the first receiving space 110 is gradually pulled out. Also, the third region 315 of the flexible display screen 31 hidden in the second receiving space 130 is gradually pulled out. The area of the part of the flexible display screen assembly 30 exposed from the housing 10 is large, so that the purpose of expanding the display part 301 of the flexible display screen assembly 30 is achieved, at the moment, the area of the display part 301 is large, and the operation of a user can be facilitated, so that the operation experience of the user is improved.

When the expansion mode needs to be switched to the narrow-screen mode, the first portion 11 and the second portion 13 can be respectively driven to move in the opposite direction relative to the third portion 15 only by reversing the motor, at this time, the scroll 20 also correspondingly reverses, the flexible display screen assembly 30 is synchronously wound, when the flexible display screen assembly moves to the limit position of the opposite movement among the first portion 11, the second portion 13 and the third portion 15, namely the three portions are completely matched together, the motor stops running, and the electronic device 100 returns to the narrow-screen state.

In addition, in some embodiments, the electronic device 100 may further include an acceleration sensor (not shown) for detecting a motion state of the electronic device 100.

Specifically, an acceleration sensor for detecting acceleration of the electronic device 100 per unit time or a preset time to detect acceleration of the electronic device 100 may be provided on the main board 101. The main board 101 can determine the motion state of the electronic device 100 according to the detection data of the acceleration sensor, for example, determine that the electronic device 100 is in a falling state when the detection value of the acceleration sensor exceeds a preset threshold, in such a case, the main board 101 can control the first driving assembly 70 and the second driving assembly 80 to drive the first portion 11 and the second portion 13 to rapidly move relative to the third portion in an opposite direction so as to rapidly retract the display portion 301 of the reduced flexible display screen assembly 30, thereby increasing the protection of the flexible display screen assembly 30.

In summary, the electronic device 100 of the embodiment of the present application includes a housing 10, a scroll 20, and a flexible display assembly 30. The housing 10 comprises a first part 11, a second part 13 and a third part 15, the first part 11 and the second part 13 are connected to the third part 15 and can move away from each other relative to the third part 15. The reel 20 includes a first reel 21 and a second reel 23, the first reel 21 being rotatably provided in the first portion 11, and the second reel 23 being rotatably provided in the second portion 13. One end of the flexible display screen assembly 30 is wound around the first reel 21 and the other end is wound around the second reel 23. Wherein the first roller 21 is rotatable to release the flexible display assembly 30 to expand the display portion 301 of the flexible display assembly 30 upon a movement of the first portion 11 away from the third portion 15, and wherein the second roller 23 is rotatable to release the flexible display assembly 30 to expand the display portion 301 of the flexible display assembly 30 upon a movement of the second portion 13 away from the third portion 15.

It is understood that, in the present embodiment, in order to realize the expansion of the display portion 301 of the flexible display screen assembly 30, the following cases may be included: 1) the first portion 11 moves away from the third portion 15, the second portion 13 is stationary relative to the third portion 15, and the first roller 21 rotates to release the flexible display screen assembly 30. 2) The second portion 13 moves away from the third portion 15, the first portion 11 is stationary relative to the third portion 15, and the second roller 23 rotates to release the flexible display screen assembly 30. 3) The first portion 11 and the second portion 13 are moved away from each other relative to the third portion 15 and the first roller 21 and the second roller 23 are rotated to release the flexible display assembly 30.

In summary, in the electronic device 100 of the embodiment of the present application, when the first portion 11 of the housing 10 moves away from the third portion 15, the first roller 21 can rotate to release the flexible display panel assembly 30, so as to expand the display portion 301 of the flexible display panel assembly 30. Upon a movement of the second portion 13 away from the third portion 15, the second roller 23 can be rotated to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. Thus, 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 can not be expanded when the large screen is not needed, so that the whole device is small in size and convenient to carry. Meanwhile, two reels are arranged to roll up and release two ends of the flexible display screen assembly 30 respectively, so that stress at two ends of the flexible display screen assembly 30 is smaller in the reel rotating process, and the unfolding process is more stable.
