A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
It will be appreciated that in this embodiment, the second portion 14 is slidable relative to the first portion 12 to move away from or towards the first portion 12. In the present embodiment, "the first part 12 and the second part 14 move away from each other" may be understood as that the second part 14 slides relative to the first part 12 and the sliding direction is away from the first part 12. In addition, in the present embodiment, the first portion 12 and the second portion 14 may also move toward each other, and the movement of the two toward each other may be understood as the second portion 14 sliding with respect to the first portion 12 with the sliding direction toward the first portion 12.
It is further noted that, in the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, e.g. as a fixed connection, a detachable connection or an integral connection; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Referring to fig. 1, 4 and 5, in the present embodiment, when the first portion 12 and the second portion 14 move toward each other to the limit position (i.e., when the first portion 12 and the second portion 14 approach each other until the first portion 12 and the second portion 14 are fit together), the first portion 12 and the second portion 14 are integrally formed into a substantially rectangular housing 10. Referring to fig. 2, 6 and 7, as first portion 12 and second portion 14 move apart (i.e., away from each other), first portion 12 and second portion 14 separate.
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 spool 20 is adapted to be coupled to a drive mechanism 70 to enable the spool 20 to rotate relative to the first portion 12 under the drive of the drive mechanism 70 to release or wind up the flexible display screen assembly 30.
It will be appreciated that the rotational positioning of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12, or may refer to the spool 20 being mounted on the first portion 12 via other media.
In addition, with continued reference to fig. 5 and 7, one end of the flexible display panel assembly 30 is connected to the second portion 14, in this embodiment, the end is fixedly connected to the second portion 14, in other embodiments, the end can also be connected to the second portion 14 through a movable mechanism, for example, the movable mechanism can be a structure for adjusting the tightness of the flexible display panel assembly 30. The other end of the flexible display assembly 30 is disposed on the spool 20 so that a portion of the flexible display assembly 30 can be wound on the spool 20.
The roll 20 may be used to roll up the flexible display screen assembly 30 and release the flexible display screen assembly 30. Wherein upon a movement of the first and second portions 12, 14 away from each other, the roller 20 is able to rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. Specifically, one end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, and the other end thereof passes through the first opening 1222 of the first portion 12 and then is connected to the reel 20 disposed in the accommodating space 120.
In this manner, upon a movement of the first and second portions 12, 14 away from each other, the spool 20 can rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. 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 closely coupled together, in which case the display portion 301 of the flexible display screen assembly 30 is not extended, and the electronic device 100 is in the narrow screen mode, in which case a portion of the flexible display screen assembly 30 is wrapped around 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.
Referring to fig. 7, when the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the first portion 12 and the second portion 14 move away from each other, so that the second portion 14 drives one end of the flexible display screen assembly 30 to move, and at this time, the reel 20 can release the flexible display screen assembly 30, so that the display portion 301 of the flexible display screen assembly 30 is enlarged, thereby improving the operation experience and the demand of the user. In such a case, the electronic device 100 is in the extended mode.
It will be appreciated that there are extreme positions in which the display area of the electronic device 100 is maximized, i.e. the area of the set of flexible display screens 32 exposed from the housing 10 is maximized, i.e. the area of the display portion 301 of the flexible display screen assembly 30 is maximized, when both the second part 14 and the first part 12 are moved away from each other (as shown in fig. 7). When the first portion 12 and the second portion 14 are brought together in close proximity and coupled, the display area of the electronic device 100 is minimized, i.e., the display portion 301 of the flexible display screen assembly 30 is minimized in area (as shown in fig. 5).
One end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, which may mean that one end of the flexible display screen assembly 30 is directly fixed to the second portion 14, or that the flexible display screen assembly 30 is fixed to the second portion 14 through other media. One end of the flexible display screen assembly 30 is not movable relative to the second portion 14.
In the embodiment of the present application, one end of the flexible display screen assembly 30 refers to a first edge of the flexible display screen assembly 30, and the other end of the flexible display screen assembly 30 refers to a second edge of the flexible display screen assembly 30, the second edge being disposed opposite to the first edge.
Specifically, referring to fig. 3, 5 and 7, the flexible display panel assembly 30 includes a flexible display panel 32 and a flexible supporting member 34, wherein the flexible display panel 32 and the flexible supporting member 34 are stacked and fixedly connected. A flexible display 32 is attached to the second portion 14, and a flexible support 34 is wound around the spool 20 and is fixedly attached to the flexible display 32.
Specifically, the flexible display screen 32 includes a first region 322 fixedly connected to the second top plate 142 and a second region 324 connected to the first region 322, the first region 322 corresponds to the second top plate 142, and the second region 324 is at least partially located in the accommodating space 120 of the first portion 12 and connected to the flexible support 34. The first region 322 may be fixedly connected to the second top plate 142 by an Optical Clear Adhesive (OCA).
The flexible support 34 is disposed at the bottom of the second region 324 and covers the second region 324, and the flexible support 34 may also be fixedly connected to the second region 324 by an Optical Clear Adhesive (OCA). In the example shown in fig. 5 and 7, the flexible support 34 comprises a first support 341 and a second support 343, the first support 341 corresponding to the second region 324, the second support 343 being wound on the reel 20, that is, in such an embodiment, the second support 343 goes beyond the second region 324 and is wound on the reel 20. Referring to fig. 5, when the electronic device 100 is in the narrow screen mode, the flexible supporting member 34 is wound around the reel 20, and the flexible display screen 32 is substantially "U" shaped.
In this way, when the electronic device 100 is in the narrow-screen mode (i.e. when the first portion 12 and the second portion 14 move toward each other to the extreme positions), only the second supporting portion 343 of the flexible supporting member 34 is rolled up by the reel 20, and the flexible display screen 32 is not directly rolled up by the reel 20, so that the degree and the 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 referring to fig. 17, in other embodiments, the flexible display 32 may correspond to the flexible support 34 and the second region 325, and the flexible support 34 and the flexible display 30 are wound together on the reel 20, that is, the reel 20 may wind up and release both the flexible support 34 and the flexible display 32 at the same time, and the specific arrangement is not limited herein.
In the present embodiment, the flexible display panel assembly 30 has a substantially U-shape, and electric components such as a main board, a sub-board, a sensor, and a battery of the electronic device 100 can be accommodated in a space surrounded by the flexible display panel assembly 30.

Referring to fig. 5 and 7, in the present embodiment, when the first portion 12 and the second portion 14 move away from each other, the flexible supporting member 34 abuts against the first portion 12 to keep the display portion 301 of the flexible display screen 32 flat.
Specifically, when the first portion 12 and the second portion 14 are separated, the flexible support 34 is disposed opposite the first top plate 122 and abuts the first top plate 122. The flexible support 34 is located between the flexible display screen 32 and the first top plate 122 and fills a gap between the flexible display screen 32 and the first top plate 122.

Referring to fig. 3, 5 and 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 move, so as to expand the display portion 301 of the flexible display panel 32.
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, the driving mechanism 70 may also simultaneously drive the roller 20 to rotate to release the flexible display assembly 30, thereby expanding 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 structure 72 includes a first transmission gear 722 and a rack portion 724. The first transmission gear 722 is connected to the second transmission structure 74 and fixed to the motor shaft 711 of the motor 71, the rack portion 724 is fixedly connected to the second portion 14, and the rack portion 724 is engaged 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 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. Thus, the rack portion 724 can be directly formed on the second top plate 142, and the integrity is good, and it is convenient to process it to understand that, in other embodiments, the rack portion 724 can also be formed separately from the second portion 14, and then the two are 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 fixedly connected to the motor shaft of the motor, and the third transmission gear 744 is connected to the second transmission gear 742 and the first transmission gear 722, that is, the third transmission gear 744 is connected to the motor shaft of the motor and 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 may be used to drive the second portion 14 to move away from the first portion 12, and simultaneously drive the spool 20 to rotate via 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 third transmission gear 744 to rotate, the third transmission gear 744 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 portion 724, the second portion 14 drives the flexible display screen assembly 30 to extend, that is, one end of the flexible display screen assembly 30 is driven to move away from the first portion 12, meanwhile, the first transmission gear can also drive the third transmission gear 722 to rotate at the same time, 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, the motor is simply 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 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 rolling up and releasing the flexible display screen assembly 30 by the roll 20, the number of the driving mechanisms 70 may be two, and the number of the roll 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 rolls 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 drive mechanism 70 may also include two synchronous motors disposed on the first portion 12, one of which is used to drive the second portion 14 relative to the first portion 12, and the other of which drives the spool 20, both using separate motors. In this way, the two motors move synchronously, and the smoothness of the movement and the reliability of the movement of the flexible display screen assembly 30 can also be ensured.
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 through the first transmission structure 72. In addition, the electronic device 100 may further include a restoring structure (not shown) coupled 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 tendency to be wound around the roller 20.
Specifically, the restoring structure may apply a force to the flexible display screen assembly 30, and the restoring structure may automatically roll up an end of the flexible display screen assembly 30 when the electronic device 100 is in the narrow screen mode. When the motor drives the second portion 14 to move away from the first portion 12, i.e., to switch from the narrow screen mode to the extended mode, the second portion 14 applies a force to one end of the flexible display assembly 30, so that the flexible display assembly 30 can overcome the force applied by the restoring structure, and the reel 20 can gradually release the flexible display assembly 30, thereby extending the display portion 301 of the flexible display assembly 30. When the motor drives the second portion 14 to move towards the first portion 12, i.e. to switch from the extended mode to the narrow screen mode, the second portion 14 gradually releases one end of the flexible display screen 32, and at this time, the reel 20 rolls up the other end of the flexible display screen assembly 30 under the action of the restoring structure, so as to maintain the balance of the flexible display screen assembly 30.
Next, the operation principle of the electronic device 100 according to the present embodiment will be described.
Referring to fig. 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 disposed on the winding shaft 20, and the other end is connected to the second portion 14, so that only a small portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrow, thereby facilitating carrying by a user.
When a user needs a larger display portion 301, the driving mechanism 70 can drive the second portion 14 to move away from the first portion 12, 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 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 roll up 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 stops operating, and the electronic device 100 returns to the narrow-screen mode.
Referring to fig. 5, in some embodiments, the electronic device 100 includes a first battery 90, and the first battery 90 is disposed in the spool 20. The first battery 90 is used to power the electronic device 100. For example, the first battery 90 may be used to provide electrical energy for rotation of the spool 20. Specifically, the first battery 90 may supply power to the motor, thereby driving the spool 20 to rotate. As another example, the first battery 90 may power the flexible display screen 32.
In this way, the first battery 90 is disposed in the scroll 20, so that the internal space of the scroll 20 can be fully utilized, and the electronic device 100 can be more compact.
It should be noted that the first battery 90 may be fixedly connected to the reel 20, or may be rotatably connected to the reel 20. Alternatively, the first battery 90 may rotate with the rotation of the spool 20, or may be fixedly disposed with respect to the spool 20 during the rotation of the spool 20.
In one example, the first battery 90 has a cylindrical shape and is disposed inside the spool 20 in the axial direction of the spool 20. Alternatively, the first battery 90 is a cylindrical battery. The axial direction of the first battery 90 is substantially parallel to the axial direction of the spool 20. In this way, the first battery 90 having a cylindrical shape is fitted to the shape of the spool 20, so that the compactness of the first battery 90 and the spool 20 can be further improved.
Referring to fig. 17 and 18, further, in some embodiments, the first battery 90 includes a casing 91 and a battery cell 92 disposed in the casing 91, and the battery cell 92 is in a sheet shape and is wound in the casing 91. Therefore, the casing 91 can protect the battery cell 92, reduce the impact on the battery cell 92, and improve the stability of the power supply of the battery cell 92. The battery cell 92 is wound, so that the compactness of the arrangement of the battery cell 92 can be improved, and the battery capacity of the battery cell 92 can be increased under the condition of the same volume of the shell.
Specifically, the housing 91 may be made of plastic, metal, or the like, and the material of the housing 91 is not limited herein. The core 92 can be formed by winding multiple layers of polymer lithium battery film materials. As shown in fig. 19, in one example, the battery cell 92 includes a positive plate 921 and a negative plate 922. A first diaphragm 923 is arranged between the positive plate 921 and the negative plate 922, and a second diaphragm 924 is arranged on the side of the positive plate 921 deviating from the first diaphragm 923. That is, the first and second separators 923, 924 may prevent the positive electrode sheet 921 from contacting the negative electrode sheet 922 to cause a short circuit when the battery cells 92 are wound. The first membrane 923 and the second membrane 924 are made of an insulating material.
Referring to fig. 20, in some embodiments, the first battery 90 includes an electrode 93, the electrode 93 is located at an axial end of the battery cell 92, and the electrode 93 is electrically connected to the battery cell 92. Since the reel 20 needs to be rotated during operation, the electrode 93 is disposed at the axial end of the first battery 90, which facilitates the first battery 90 to supply power to the outside through the reel 20. It is understood that the electrode 93 is used to provide an interface for charging and discharging the battery cell 92.
Specifically, the electrode 93 includes a positive electrode 931 and a negative electrode 932, and the positive electrode 931 and the negative electrode 932 are disposed at intervals. The positive electrode 931 and the negative electrode 932 are each annular. It is understood that the potential of the positive electrode 931 is larger than that of the negative electrode 932.
Referring to fig. 21 and 22, in some embodiments, the electronic device 100 includes a connector 200, and the connector 200 includes a body 202 and a resilient contact 204 disposed on the body 202. The elastic contact portion 204 elastically abuts against the electrode 93. The connector 200 is electrically connected to a main board (not shown) of the electronic device 100.
In this way, the connector 200 can be connected to the first battery 90 more stably, thereby improving the stability of power supply of the first battery 90. Specifically, the body 202 may have a cylindrical shape, and the diameter of the body 202 is substantially the same as the diameter of the first battery 90. The elastic contact portion 204 may be, for example, a metal spring piece or an elastic terminal.
In the present embodiment, the number of the elastic contact portions 204 is two, and one of the elastic contact portions 204 is in contact with the positive electrode 931 and the other elastic contact portion 204 is in contact with the negative electrode 932.
It is understood that the electronic device 100 has a motherboard on which circuit elements such as a processor are disposed, and the motherboard can control the power consumption state of each power consumption component of the electronic device 100.

It should be noted that the term "fit" as used herein is to be understood as meaning that the two are in contact without affecting the sliding movement therebetween, or that the gap between the two is within the tolerance of assembly.
In this embodiment, the first portion 11 is slidable relative to the third portion 15 to move away from or toward one side of the third portion 15, and the second portion 13 is also slidable relative to the third portion 15 to move away from or toward the other side of the third portion 15. Referring to fig. 24 and 28, in the present embodiment, "the first portion 11 and the second portion 13 move away from each other" may 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 the second portion 13 is away from the other side of the third portion 15 and the sliding direction is away from the third portion 15, for example, moving from the state shown in fig. 23 and 27 to the state shown in fig. 25 and 28. In addition, in the present embodiment, the first portion 11 and the second portion 13 can also move toward each other, 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. 25 and 28 to the state shown in fig. 23 and 27 shown in fig. 25 and 28.
It is understood that in other embodiments, "the first portion 11 moves away from the second portion 13" may also be understood as the first portion 11 is stationary relative to the third portion 15 and the second portion 13 is distal from the third portion 15, or the first portion 11 is distal from the third portion 15 and the second portion 13 is stationary relative to the third portion 15.
Referring to fig. 23, 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 the third portion 15 to cooperate with each other), the first portion 11, the second portion 13, and the third portion 15 form a substantially rectangular housing 10. Referring to fig. 25, when the first portion 11 and the second portion 13 move away from each other (i.e., they move away from each other), the first portion 11, the second portion 13, and the third portion 15 are separated.
Referring to fig. 27 and 28, 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. The first reel 21 is connected to one end of the flexible display screen assembly 30 for rolling up or releasing the 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 reel 23 is connected to the other end of the flexible display assembly 30 for rolling up or releasing the flexible display assembly 30, that is, the first reel 21 and the second reel 23 are respectively connected to both ends 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.
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. 27 and 28, the flexible display screen assembly 30 is fixedly connected at both ends to the first roller 21 and the second roller 23, respectively. Specifically, one end of the flexible display screen assembly 30 is connected to the first roller 21 after passing through the first opening 1111 of the first portion 11, and the other end is connected to the second roller 23 after passing 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.
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.
Alternatively, 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.
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 in other embodiments, where "the first portion 11 is moved away from the second portion 13" is understood to mean that the first portion 11 is stationary relative to the third portion 15, and the second portion 13 is moved away from the third portion 15, only the first roller 21 is rotated to release one end of the flexible display screen assembly 30 to expand the display portion 301. In addition, where "the first portion 11 moves away from the second portion 13" is to be understood as the first portion 11 moving away from the third portion 15, and the second portion 13 is stationary relative to the third portion 15, only the second roller 23 is rotated to release one end of the flexible display screen assembly 30 to expand the display portion 301.
Further, it is understood that, in the present 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 panel assembly 30 is not expanded, and the electronic device 100 is in the narrow screen mode (for example, the state shown in fig. 23 and 27), in which one end of the flexible display panel assembly 30 is wound around the first reel 21 and the other end is wound around 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 necessary 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, so that the first portion 11 and the second portion 13 are away from each other, and 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 separation, the first roller 21 and the second roller 23 rotate simultaneously to release the two ends of the flexible display assembly 30, so as to expand the display portion 301 of the flexible display assembly 30, in which case the electronic device 100 is in the expansion mode (for example, the state shown in fig. 25 and 28).
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. 25). When the first, second and third portions 11, 13, 15 are brought together closely and fully, the display area of the electronic device 100 is minimized, i.e., the display portion 301 of the flexible display screen assembly 30 is minimized (see fig. 23).
Note that in this embodiment, the "display portion 301 of the flexible display panel assembly 30" may be understood as a portion exposed from the housing 10.
Specifically, referring to fig. 27 and 28, 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. 27 and 28, both ends of the flexible support 33 extend beyond the flexible display screen 31, and the extended portions are connected to the first reel 21 and the second reel 23, respectively. Referring to fig. 27, when the electronic device 100 is in the narrow-screen mode, one end of the flexible supporting member 33 is wound around the first roller 21, and the other end is wound around the second roller 23, the flexible display screen 31 is substantially racetrack-shaped, and the main board, the sub-board, the sensors, the battery and other electrical components of the electronic device 100 can be accommodated in the space surrounded by the flexible display screen assembly 30. Like this, flexible display screen assembly 30's the mode of setting up can not influence electric elements's such as mainboard and battery putting, the effectual utilization ratio that improves the space is favorable to piling up and putting of electric elements such as mainboard, battery.
In addition, when the electronic device 100 is in the narrow screen mode, only the connection segment of the flexible support member 33 is 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 roller 21 and the second roller 23 after completely corresponding to the flexible support 33.
Referring to fig. 27 and 28, in the present embodiment, when the first portion 11 and the second portion 13 move away from each other, the flexible supporting member 33 supports against the first portion 11 and the second portion 13 to keep the flexible display screen 31 flat. When the first and second portions 11, 13 are separated, the flexible support 33 conforms to the first and second portions 11, 13. 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.
In addition, with continued reference to fig. 3, 5 and 7, a first tooth 331 is formed at the bottom of the flexible supporting member 33, 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.
Referring to fig. 27 and 28 again, the limiting member 40 includes a first limiting member 41 and a second limiting member 43, the first limiting member 41 is rotatably disposed in the first portion 11 and located in the first receiving space 110, the first limiting member 41 is cylindrical, and a second tooth portion 411 is formed on a circumference of the first limiting member 41.
The second stopper 43 is rotatably disposed in the second portion 13, is located in the second receiving space 130, and is symmetrical to the first stopper 41, the second stopper 43 is also cylindrical, and a third tooth portion 431 is formed on the circumference of the second stopper 43.
The second tooth 411 and the third tooth 431 are both used to engage with the first tooth 331 on the flexible support 33 to support the flexible display assembly 30 and to guide the expansion of the flexible display assembly 30.
Thus, the first limiting member 41 and the second limiting member 43 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 runway-type state. In addition, the engagement of the first and second limiting members 41 and 43 with the flexible supporting member 33 can support the flexible display panel assembly 30 and can guide the first and second reels 21 and 23 to release the flexible display panel assembly 30 to maintain the smooth unwinding of the flexible display panel assembly 30.
Specifically, in the present embodiment, the first limiting member 41 is a guide gear, the first limiting member 41 is disposed at a position corresponding to the first opening 1111, one end of the flexible supporting member 33 is wound around the second limiting member 43, and the first tooth 331 and the second tooth 411, which are flexible supporting and reducing, are engaged with each other. The second position-limiting member 43 may also be two guide gears, the second position-limiting member 43 is disposed at a position corresponding to the second opening 1311, the other end of the flexible supporting member 33 is wound around the second position-limiting member 43, and the first tooth 331 and the third tooth 431 of the flexible supporting member 33 are engaged with each other. That is, one end of the flexible display panel assembly 30 passes through the first opening 1111 and is connected to the first winding shaft 21 after passing around the first stopper 41, and the other end of the flexible display panel assembly 30 passes through the second opening 1311 and is connected to the second winding shaft 23 after passing around the second stopper 43. When the first portion 11 and the second portion 13 are far away from each other, the first stopper 41 and the second stopper 43 are gradually rotated by the flexible support 33, and the first roller 21 and the second roller 23 gradually release the flexible support 33, so that more parts of the flexible display screen 31 are exposed from the housing 10 to achieve the purpose of expanding the display portion 301. In addition, referring to fig. 27, in the present embodiment, the structures of the first limiting member 41 and the second limiting member 43 are substantially the same.
It is understood that, in other embodiments, the first limiting member 41 and the second limiting member 43 may not be formed with a tooth portion, but may be directly an optical axis or a roller, and the flexible display panel assembly 30 directly passes by the roller, so that the first limiting member 41 and the second limiting member 43 can also support and guide the flexible display panel 31.
Referring to fig. 27 and 28, in the present embodiment, the camera 60 is disposed in the accommodating space 150 of the third portion 15, and the cover 50 is disposed at the bottom of the third portion 15 to close the accommodating space 150. That is, in the present embodiment, when the second portion 13 moves relative to the first portion 11, the camera 60 does not follow the movement, and when the electronic device 100 is in the extended mode, the camera 60 is located at a middle position of the entire flexible display screen 31.
The cover 50 is detachably connected to the first portion 11, so that the cover 50 can be conveniently detached to repair and replace the electrical components such as the motherboard, the battery or the sensor stacked in the accommodating space 150.
The cover 50 is provided with a light-transmitting portion 56 corresponding to the camera 60, and the camera 60 captures an image through the light-transmitting portion 56. In this way, the camera 60 can be protected without affecting the shooting effect of the camera 60, so that the camera 60 is prevented from being exposed outside the housing 10 directly and being scratched accidentally.
Referring to fig. 24, 26 and 27, in this embodiment, the cover 50 includes a first connection portion 51, a second connection portion 53 and a third connection portion 55, the first connection portion 51 is fixedly connected or detachably connected with the first portion 11 and closes the first receiving space 110, the second connection portion 53 is fixedly connected or detachably connected with the second portion 13 and closes the second receiving space 130, and the third connection portion 55 is fixedly connected or detachably connected with the third portion 15 and closes the receiving space 150.
Referring to fig. 24, when the electronic device 100 is in the narrow-screen mode, that is, the first portion 11 and the second portion 13 move to the extreme positions and completely mate with the third portion 15, the first connecting portion 51, the second connecting portion 53, and the third connecting portion 55 are spliced together to form the cover 50 of the electronic device 100. Specifically, referring to fig. 24, 26 and 27, in such an embodiment, the first connection portion 51 and the second connection portion 53 are symmetrical about the third connection portion 55, a convex arc is formed on each of the first connection portion 51 and the second connection portion 53, and concave arcs matched with the convex arc are formed on both sides of the third connection portion 55, and when the electronic device 100 is in the narrow-screen mode, the concave arcs and the convex arcs are spliced together to realize splicing of the first connection portion 51 and the third connection portion 55 and splicing of the second connection portion 53 and the third connection portion 55. It can be understood that the first connecting portion 51, the second connecting portion 53 and the third plate can be made into other forms, for example, the three portions are rectangular, and can be directly spliced to form the cover 50, for example, the two symmetrical sides of the third connecting portion 55 are formed with regularly arranged protrusions, and the first connecting portion 51 and the second connecting portion 53 are formed with grooves corresponding to the protrusions, so that the form of the housing 10 can be enriched to improve the aesthetic feeling when the electronic device 100 is in the expansion mode.
Further, in such an embodiment, the first connecting portion 51, the second connecting portion 53 and the third connecting portion 55 can be designed to have a plurality of different color effects, which can enrich the appearance effect of the electronic device 100.
In the present embodiment, the number of the driving mechanisms (not shown) is two, and two driving mechanisms may be provided in the first and second receiving spaces 110 and 130, respectively. A driving mechanism disposed in the first receiving space 110 may be connected to the first top plate 111 and the first roller 21 and may drive the first roller 21 to rotate to release one end of the flexible display panel assembly 30 while driving the first portion 11 to move away from the third portion 15.
A drive mechanism disposed in the second receiving space 130 may be connected to the second top plate 131 and the second roller 23 and used to drive the second roller 23 to rotate while driving the second portion 13 to move away from the third portion 15 to release the other end of the flexible display panel assembly 30.
Specifically, in the present embodiment, the specific structure of the driving mechanism may be similar to that of the driving mechanism 70 in the above-described embodiment, for example, as shown in fig. 5 and 7, and will not be described in detail here in order to avoid redundancy.
In this embodiment, when the display area of the electronic device 100, that is, the display portion 301 of the flexible display panel assembly 30 needs to be expanded, the driving mechanism disposed in the first accommodating space 110 can drive the first portion 11 to move away from the third portion 15 and the second portion 13, and at the same time, the driving mechanism drives the first roller 21 to rotate, so that the first roller 21 can gradually release the flexible display panel assembly 30, thereby achieving the purpose of expanding the display portion 301 of the flexible display panel assembly 30 (for example, moving from the state shown in fig. 27 to the state shown in fig. 28).
When the flexible display panel 301 needs to be reduced, the motor of the driving mechanism is only required to rotate reversely to drive the first portion 11 to move toward 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, from the state shown in fig. 28 to the state shown in fig. 27).
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, in the display area of the electronic device 100, the driving mechanism 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 driving mechanism drives the second roller 23 to rotate, so that the second roller 23 can gradually release the flexible display panel assembly 30, thereby extending the display portion 301 of the flexible display panel assembly 30.
It can be understood that, in the present embodiment, when the display portion 301 of the flexible display panel assembly 30 needs to be expanded, one of the two driving mechanisms 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 expand the flexible display panel assembly 30. Of course, the same purpose can be achieved by using two driving mechanisms to respectively drive 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.
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. 23, 25, 27, and 28, 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. 23 and 27, the electronic apparatus 100 is in the narrow screen mode, and in the state shown in fig. 25 and 28, the electronic apparatus 100 is in the extended mode. When in the narrow screen mode, the first portion 11, the second portion 13 and the third portion 15 cooperate with each other to form the housing 10, one end of the flexible display screen assembly 30 is disposed on the first roller 21, and the other end is disposed on the second roller 23, at this time, only a small portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrow, so that the display device is convenient for a user to carry.
When a user needs a larger display section 301, the first section 11 and the second section 13 are driven by two driving mechanisms to move away from each other relative to the third section 15, respectively, and the moving directions of the first section 11 and the second section 13 are opposite. At this time, the driving mechanism simultaneously drives the first roller 21 and the second roller 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 opposite directions relative to the third portion 15 only by enabling the motor of the driving mechanism to rotate reversely, at this time, the scroll 20 also rotates reversely correspondingly, the flexible display screen assembly 30 is synchronously rolled up, 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 the embodiment of fig. 23-28, the number of first batteries 90 may be two, with one first battery 90 disposed in the first spool 21 and the other first battery 90 disposed in the second spool 23. This makes it possible to fully utilize the space of the first reel 21 and the second reel 23. Of course, the number of the first batteries 90 may be one, and the first batteries 90 are provided in the first reel 21 or the second reel 23.
It should be noted that, for other expanded portions of the electronic device 100 in the embodiments of fig. 23-28, please refer to the same or similar portions in the above embodiment in which the housing 10 includes the first portion 11 and the second portion 13, and further description is omitted here.
In some embodiments, the position limiting element 40 may be omitted, so as to reduce the number of components of the electronic device 100 and save the space of the electronic device 100. Referring to fig. 29, the spool 20 may be located at an end of the first portion 12 remote from the second portion 14. In the example of fig. 29, the stopper 40 is omitted.
Referring to fig. 29-31 again, in some embodiments, the electronic device 100 includes a telescopic support assembly 160, and the telescopic support assembly 160 is disposed in the housing 10. The telescoping support assembly 160 is adapted to extend toward the display portion 301 of the flexible display screen assembly 30 and to abut the display portion 301 of the flexible display screen assembly 30 when the first portion 12 and the second portion 14 are moved apart.
In this way, the telescopic supporting component 160 extends towards the display part 301 of the flexible display screen component 30 and abuts against the display part 301 of the flexible display screen component 30, so that the display part 301 of the flexible display screen component 30 can be supported, and thus the deformation degree of the flexible display screen component 30 after being touched after being flattened from the scroll 20 can be reduced, so that the display part 301 of the flexible display screen component 30 keeps flat, and the display effect of the flexible display screen component 30 is ensured. In addition, the telescopic supporting component 160 occupies a small space in the contracted state, which is beneficial to miniaturizing the electronic device 100.
It should be noted that the extension of the telescoping support assembly 160 may refer to the overall extension of the telescoping support assembly 160, or the partial extension of the telescoping support assembly 160. The telescopic support assembly 160 supports against the display portion 301 of the flexible display screen assembly 30, may refer to the telescopic support assembly 160 supporting against the display portion 301 of the whole flexible display screen assembly 30, and may refer to the telescopic support assembly 160 supporting against the display portion 301 of the flexible display screen assembly 30.
With the flexible display screen assembly 30 fully deployed, the telescoping support assembly 160 may support the extended portion of the flexible display screen assembly 30. Therefore, the display part 301 of the flexible display screen assembly 30 can be supported after being expanded, and the display part 301 of the flexible display screen assembly 30 is prevented from being greatly deformed after being touched.
It should be noted that the "expanded portion" may be understood as the portion of flexible display assembly 30 extending from first portion 12 and flattening during the process of moving first portion 12 and second portion 14 away from each other, i.e., enlarged display portion 301 of flexible display assembly 30. Hereinafter, the same or similar descriptions will be referred to for understanding.
It will be appreciated that the telescoping support assembly 160 may also be collapsed, and the display portion 301 of the flexible display screen assembly 30 may be at least partially supported on the telescoping support assembly 160 when the telescoping support assembly 160 is in the collapsed state. Alternatively, where the telescoping support assembly 160 is sufficiently long, the display portion 301 of the flexible display screen assembly 30 may be integrally supported on the telescoping support assembly 160. The telescoping support assembly 160 may be sequentially extended as the flexible display screen assembly 30 is extended to support the extended portion of the flexible display screen assembly 30.
It is noted that in the embodiment of fig. 29, the flexible support 34 of the flexible display assembly 30 discussed above may be omitted.
Referring to fig. 30-31, in some embodiments, the telescopic supporting assembly 160 includes a plurality of supporting members 161, the supporting members 161 are arranged along the extending direction of the flexible display panel assembly 30, the supporting members 161 are used for extending and contracting along the thickness direction of the display portion 301 of the flexible display panel assembly 30, and when the first portion 12 and the second portion 14 move away from each other, at least a portion of the supporting members 161 extend and abut against the display portion 301 of the flexible display panel assembly 30.
In this manner, the plurality of supporting members 161 are arranged along the expansion direction of the flexible display panel assembly 30 such that each supporting member 161 can be independently extended and contracted, and the supporting members 161 can be extended one by one to support the display portion 301 of the flexible display panel assembly 30 during the expansion of the display portion 301 of the flexible display panel assembly 30.
It should be noted that the flexible display panel assembly 30 is generally rectangular when flattened, and the flexible display panel assembly 30 is expanded along its length. At this time, the expansion direction of the flexible display screen assembly 30 is a length direction of the display portion 301 of the flexible display screen assembly 30. In addition, the extended height of each support 161 is uniform so that the display portion 301 of the flexible display screen assembly 30 can be supported on the support 161 in a flat state.
As in the example of fig. 3 and 6, the flexible display screen assembly 30 is extended along the lateral direction of the electronic device 100, and at this time, the plurality of supports 161 are arranged along the lateral direction of the electronic device 100. The plurality of supporting members 161 may be arranged at intervals or may be arranged to abut against each other.
The number of supports 161 may be a number greater than or equal to 2, 3, 4, etc.
Further, in some embodiments, the support member 161 includes an elastic portion 163 and a support portion 162 connected to the elastic portion 163, the elastic portion 163 is connected to the first portion 12, the support portion 162 abuts against the second portion 14 to compress the elastic portion 163 when the flexible display screen assembly 30 is in the rolled-up state, and the support portion 162 is spaced from the second portion 14 to extend the elastic portion 163 when the flexible display screen assembly 30 is in the rolled-out state, so that the support portion 162 abuts against the display portion 301 of the flexible display screen assembly 30.
In this way, the elastic part 163 may change the overall height of the support 161 after being stretched, so that the support part 162 may support the display part 301 of the flexible display screen assembly 30. When the flexible display screen assembly 30 is in the rolled state, the flexible display screen assembly 30 is partially rolled on the roller 20, and the display portion 301 of the flexible display screen assembly 30 has the smallest area. At this point, the first portion 12 and the second portion 14 are brought closer together. When the flexible display screen assembly 30 is in the unfolded state, the display portion 301 of the flexible display screen assembly 30 has the largest area, and the first portion 12 and the second portion 14 are away from each other.
When the flexible display panel assembly 30 is in the rolled state, the supporting portion 162 is spaced from the display portion 301 of the flexible display panel assembly 30, and at this time, the display portion 301 of the flexible display panel assembly 30 can be supported on the second portion 14, so that the amount of deformation of the display portion 301 of the flexible display panel assembly 30 can be reduced.
When the flexible display panel assembly 30 is in the unfolded state, since the area of the display portion 301 of the flexible display panel assembly 30 is increased and the area of the display portion 301 of the flexible display panel assembly 30 supported by the second portion 14 is not changed, at this time, since the supporting member 161 is extended, the supporting portion 162 can support the extended portion of the flexible display panel assembly 30, so that the overall deformation amount of the display portion 301 of the flexible display panel assembly 30 can be reduced.
Specifically, the supporting portion 162 has an elongated shape, and a length direction of the supporting portion 162 extends along a width direction of the flexible display panel assembly 30. In other words, the length direction of the supporting portion 162 extends along the longitudinal direction of the electronic device 100. The length of the support portion 162 is substantially the same as the width of the flexible display assembly 30 so that the support portion 162 can integrally support the flexible display assembly 30 in the width direction of the flexible display assembly 30.
As shown in fig. 24, each of the supporting portions 162 is provided with an elastic portion 163 at both ends in the length direction, so that the stress of the supporting portion 162 is equalized, thereby better supporting the flexible display screen assembly 30. Of course, two or more elastic parts 163 may be provided in the support part 162.
The elastic portion 163 is an elastic element such as a spring, or a rubber. The elastic portion 163 may be elastically deformed by bending or compression to change its length, thereby changing the overall height of the telescopic support assembly 160.
Referring to fig. 30, in some embodiments, the first top plate 122 is opposite to the display portion 301 of the flexible display screen assembly 30, the second top plate 142 is opposite to the first top plate 122, and the telescopic supporting assembly 160 is located between the first top plate 122 and the second top plate 142.
The flexible portion 163 is supported on the first top plate 122, the support portion 162 abuts against the second top plate 142 to compress the flexible portion 163 when the flexible display screen assembly 30 is in the rolled state, and the support portion 162 is spaced from the second portion 14 to extend the flexible portion 163 when the flexible display screen assembly 30 is in the rolled state.
As such, the first top plate 122 may provide support for the elastic part 163, so that the support 161 may stably support the display portion 301 of the flexible display screen assembly 30 when the flexible display screen assembly 30 is touched, reducing the amount of deformation of the display portion 301 of the flexible display screen assembly 30.
It can be understood that referring to fig. 29 and 30, when the flexible display screen assembly 30 is in the rolled state, the display portion 301 of the flexible display screen assembly 30 is fixedly connected to the upper surface of the second top board 142. At this time, the second top plate 142 may provide support for the display portion 301 of the flexible display screen assembly 30. When the first portion 12 and the second portion 14 move away from each other, the first top plate 122 and the second top plate 142 are displaced, and a gap is formed between the upper surface of the first top plate 122 and the upper surface of the second top plate 142.
At this time, the plurality of supporting portions 162 are gradually released, the supporting portions 162 are elastically ejected to the display portion 301 of the flexible display screen assembly 30 by the elastic portion 163, so that the gap between the first top plate 122 and the flexible display screen assembly 30 can be filled after the telescopic supporting assembly 160 is extended, and the display portion 301 of the flexible display screen assembly 30 can be kept flat when the flexible display screen assembly 30 moves, thereby reducing the phenomena of pressing deformation, collapse and slippage when the electronic device 100 is in the expansion mode, and improving the operation experience of the user when the flexible display screen assembly 30 is touched.
Further, the first top plate 122 is formed with a receiving groove 123, and the elastic portion 163 is inserted into the receiving groove 123. In other words, an end of the elastic portion 163 away from the display portion 301 of the flexible display panel assembly 30 is received in the receiving groove 123. Thus, the receiving groove 123 can further support the elastic portion 163, and prevent the elastic portion 163 from being twisted, so that the elastic portion 163 can be elastically deformed in the thickness direction of the display portion 301 of the flexible display panel assembly 30.
Referring to fig. 30, in some embodiments, the supporting portion 162 is formed with a first guiding surface 164, the second top plate 142 is formed with a second guiding surface 145, and the second guiding surface 145 is used for guiding the second top plate 142 to press against the supporting portion 162 in cooperation with the first guiding surface 164 during the rolling process of the flexible display screen assembly 30, so as to compress the elastic portion 163.
Or, when the first portion 12 and the second portion 14 move closer to each other, the area of the display portion 301 of the flexible display screen assembly 30 is reduced, and at this time, the display portion 301 of the flexible display screen assembly 30 may not need to be supported by the supporting portion 161, and the second top portion may press against the supporting portion 162, so that the supporting portion 161 is switched from the extended state to the retracted state, which may make the overall structure of the electronic device 100 more compact.
In this embodiment, the first guide surface 164 and the second guide surface 145 are both inclined surfaces, and in other embodiments, the first guide surface 164 and/or the second guide surface 145 may be surfaces having other shapes such as an arc surface.
It should be noted that in the example of fig. 29, the electronic device 100 omits the limiting member 40 and the driving mechanism 70, and at this time, the second portion 14 may be manually pulled to expand the display portion 301 of the flexible display screen assembly 30 and extend the telescopic support assembly 160.
Referring to fig. 32, in some embodiments, the reel 20 and the limiting member 40 may be provided with a first battery 90, and the first battery 90 is used for supplying power to the electronic device 100. It is understood that, at this time, the number of the first batteries 90 is at least two. The at least two first batteries 90 may increase the battery capacity of the electronic device 100, thereby improving the endurance of the electronic device 100.
Further, the first battery 90 may have a cylindrical shape and be disposed in the limiting member 40 along the axial direction of the limiting member 40.
It is understood that in other embodiments, the first battery 90 may be provided only in the limiting member 40. Alternatively, the first battery 90 is disposed in the limiting member 40.
It should be noted that the example explanations of fig. 1 to fig. 31 are applicable to the example of fig. 32, and further description of other parts of the electronic device 100 illustrated in fig. 32 is omitted here.
