In this embodiment, the term "the first portion 12 and the second portion 14 move apart" is understood to mean that the second portion 14 slides relative to the first portion 12 and the sliding direction is away from the first portion 12, i.e. moves from the first position a to the second position B. In addition, in the present embodiment, the first portion 12 and the second portion 14 may also move in opposite directions, and the two moving in opposite directions may be understood as that the second portion 14 slides relative to the first portion 12 and the sliding direction moves toward the first portion 12, that is, from the second position B to the first position a.
It should also be noted that in the description of the present application, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 1, 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 and the first portion 12 and the second portion 14 are engaged together), the second portion 14 is located at the first position a, and the first portion 12 and the second portion 14 integrally form a substantially rectangular housing 10. Referring to fig. 2, 6 and 7, when the first portion 12 and the second portion 14 are moved apart (i.e., are moved away from each other), the second portion 14 is away from the first portion 12, and when the two are moved apart to the limit position, the second portion 14 is located at the second position B, that is, in the present embodiment, the second portion 14 is capable of moving between the first position a and the second position B relative to the first portion 12. It should be noted that, herein, the second portion 14 moving away from the first portion 12 may be understood as moving the second portion 14 from the first position a to the second position B, and the second portion 14 moving toward the first portion 12 may be understood as moving the second portion 14 from the second position B to the first position a.
Referring to fig. 3, 5 and 7, the spool 20 is rotatably disposed in the first portion 12, specifically, the spool 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 such that the spool 20 is rotatable relative to the first portion 12 under the drive of the drive mechanism 70 to release or wind up the flexible display assembly 30.
It is understood that the rotational disposition of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12 or may refer to the spool 20 being mounted on the first portion 12 through other media.
In addition, with continued reference to fig. 5 and 7, the flexible display assembly 30 is fixedly attached at one end to the second portion 14 and is wound around the spool 20 at the other end. The reel 20 may be used to roll up the flexible display assembly 30 and release the flexible display assembly 30. Wherein upon a separate movement of the second portion 14 relative to the first portion 12, i.e. movement of the second portion 14 from the first position a to the second position B, the reel 20 can be rotated to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. Specifically, one end of the flexible display assembly 30 is fixedly connected to the second portion 14, and the other end is connected to the reel 20 disposed in the accommodating space 120 after passing through the first opening 1222 of the first portion 12.
In this manner, upon a separate movement of the second portion 14 relative to the first portion 12, i.e., movement of the second portion 14 from the first position a to the second position B, the spool 20 can be rotated to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30. In this way, the size of the screen display area of the electronic device 100 can be freely adjusted, the display portion 301 of the flexible display screen assembly 30 can be expanded when a large screen is required to be used to improve the operation experience of a user, and meanwhile, the display portion 301 can not be expanded when the large screen is not required to be used, so that the whole display device is small in size and convenient to carry.
It will be appreciated that referring to fig. 5, in one instance where the first portion 12 and the second portion 14 are closely coupled together, i.e., where the second portion 14 is in the first position a, the display portion 301 of the flexible display assembly 30 is not expanded, and the electronic device 100 is in the narrow screen mode, where a portion of the flexible display assembly 30 is rolled up on the roller 20 and a portion is positioned over the first top plate 122 and exposed from the housing 10 for display. It should be noted that, in the present embodiment, the "display portion 301 of the flexible display screen assembly 30" may be understood as a portion located above the second top plate 142 of the second portion 14, that is, a portion exposed from the housing 10 for display.
Referring to fig. 7, when the display portion 301 of the flexible display assembly 30 needs to be expanded, the second portion 14 moves away from the first portion 12, that is, the second portion 14 moves from the first position a to the second position B, so that the second portion 14 drives the flexible display assembly 30 to stretch, and at this time, the reel 20 can release the flexible display assembly 30, so that the display portion 301 of the flexible display assembly 30 is enlarged, and thus the operation experience and the requirements of the user are improved. In such a case, the electronic device 100 is in the extended mode.
It will be appreciated that when the second portion 14 is in the second position B, 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 for display is maximized, i.e., the display portion 301 of the flexible display screen assembly 30 is maximized (as shown in fig. 7). When the first portion 12 and the second portion 14 are close together and are coupled together, i.e., the second portion 14 is in the first position a, the display area of the electronic device 100 is at a minimum, i.e., the display portion 301 of the flexible display assembly 30 is at a minimum area (as shown in fig. 5).
In this embodiment, one end of the flexible display assembly 30 is fixedly connected to the second portion 14, which may refer to that one end of the flexible display assembly 30 is directly fixed to the second portion 14, or may refer to that the flexible display assembly 30 is fixed to the second portion 14 through other mediums. One end of the flexible display assembly 30 is not movable relative to the second portion 14.
In an embodiment of the present application, one end of the flexible display assembly 30 refers to a first edge of the flexible display assembly 30, and the other end of the flexible display assembly 30 refers to a second edge of the flexible display assembly 30, the second edge being disposed opposite the first edge.
In particular, referring to fig. 3, 5 and 7, the flexible display assembly 30 includes a flexible display 32 and a flexible support 34, the flexible display 32 and the flexible support 34 being stacked and fixedly connected.
Referring to fig. 5, the flexible display screen 32 includes a first region 322 and a second region 324 connected to the first region 322. The first region 322 is attached to the second top plate 142, the first region 322 corresponds to the second top plate 142, and the first region 322 can be fixedly connected with the second top plate 142 through optical cement (Optically Clear Adhesive, OCA). The second region 324 is at least partially located within the receiving space 120 of the first portion 12 and is disposed against the flexible support 34.
The flexible support 34 is disposed at the bottom of the second region 324 and completely covers the second region 324, and the flexible support 34 may be fixedly connected with the second region 324 through optical cement (Optically Clear Adhesive, OCA). In the example shown in fig. 5 and 7, the flexible support 34 completely covers and extends beyond the second area 324, and the excess portion of the flexible support 34 is connected to the spool 20, i.e. the excess portion is wound on the spool 20. Referring to fig. 5, when the electronic device 100 is in the narrow screen mode, the flexible support 34 is wound on the reel 20, and the flexible display 32 has a substantially U-shape. In this way, the supporting area of the flexible supporting member 34 is large, so that the phenomenon of pressing deformation and the like of the flexible display screen 32 can be reduced.
Thus, when the electronic device 100 is in the narrow-screen mode (i.e., the second portion 14 is located at the first position a), the reel 20 is only rolled up by the flexible supporting member 34, and the flexible display screen 32 is not directly rolled up by the reel 20, so that the bending degree and the bending frequency of the flexible display screen 32 can be reduced, and the service life of the flexible display screen 32 is prolonged. Of course, it will be appreciated that in other embodiments, the flexible display 32 may be coupled to the spool 20 after being fully mated with the flexible support 34, and the spool 20 may simultaneously retract and simultaneously release both the flexible support 34 and the flexible display 32, and the specific arrangement is not limited herein. In addition, the flexible supporting member 34 completely covers the second area 324, and the supporting area of the flexible supporting member 34 is larger, so that the phenomena of pressing deformation and the like of the flexible display screen 32 can be reduced.
In the present embodiment, the flexible display 32 has a substantially U-shape, and the main board 101, the sub-board 103, the sensor, the battery 102, and other electrical components of the electronic device 100 can be housed in the space surrounded by the flexible display module 30. In this way, the arrangement mode of the flexible display screen assembly 30 does not affect the placement of the electrical elements such as the main board 101 and the battery 102, effectively improves the space utilization rate, and is beneficial to the stacking and placement of the electrical elements such as the main board 101 and the battery 102.
Referring to fig. 5 and 7, in the present embodiment, the flexible support 34 abuts the first portion 12 to keep the display portion 301 of the flexible display screen 32 flat during the second portion 14 moves away from the first portion 12.
Specifically, when the first portion 12 and the second portion 14 are separated, the flexible support 34 is disposed opposite the first top plate 122 and conforms to the first top plate 122. The flexible support 34 is located between the flexible display screen 32 and the first top plate 122 and fills the gap between the flexible display screen 32 and the first top plate 122. That is, in the present embodiment, the thickness of the flexible support 34 is equal to the distance between the upper surface of the first portion 12 and the upper surface of the second portion 14.
It will be appreciated that referring to fig. 7, when the second portion 14 moves away from the first portion 12, i.e. from the first position a to the second position B, there is a height difference between the upper surface of the first top plate 122 and the upper surface of the second top plate 142, and the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, the flexible support 34 abuts against the first top plate 122 of the first portion 12, i.e. the flexible support 34 fills the gap between the flexible display screen 32 and the first top plate 122. That is, since the first top plate 122 and the second top plate 142 are attached to each other up and down, the flexible display screen 32 is fixedly connected to the upper surface of the second top plate 142, and therefore, the thickness of the flexible supporting member 34 is equal to the thickness of the second top plate 142, and the height difference between the first top plate 122 and the second top plate 142, that is, the gap between the flexible display screen 32 and the first top plate 122 is filled, so that the flexible display screen 32 can be kept flat during movement, and further, the phenomenon that the flexible display screen 32 collapses when touched and pressed when the electronic device 100 is in the expansion mode is avoided, and the operation experience of a user is improved.
In addition, with continued reference to fig. 3, 5 and 7, the bottom of the flexible support 34 is formed with a first tooth 342, and the first tooth 342 is configured to engage with the limiter 40 so as to support the flexible display assembly 30 at the limiter 40 and maintain smooth movement of the flexible display assembly 30.

In this way, the flexible support 34 may be attracted to the first top panel 122 as the second portion 14 moves away from the first portion 12 to expand the display portion 301 of the flexible display screen assembly 30. This prevents the flexible display assembly 30 from being misplaced or shifted during operation.
Referring to fig. 5, 7 and 8, the limiting member 40 is rotatably disposed in the accommodating space 120 of the first portion 12 and exposed from the first opening 1222, the middle portion of the flexible display screen assembly 30 is wound on the limiting member 40, and the limiting member 40 is used for limiting the shape of the flexible display screen assembly 30.
Specifically, the limiting member 40 has a columnar shape, and a second tooth portion 42 is formed on the circumference of the limiting member 40, and the second tooth portion 42 is used for meshing with a first tooth portion 342 on the flexible support member 34 to support the flexible display screen assembly 30 and guide the expansion of the flexible display screen assembly 30. It is understood that the middle portion of the flexible display assembly 30 may be understood as the location between the two ends of the flexible display assembly 30.
In this way, the limiting member 40 can limit the form of the flexible display assembly 30, so that the display portion 301 of the flexible display assembly 30 can be in a flat state, i.e. the flexible display assembly 30 can be kept in a U-shaped state. In addition, the engagement of the stop member 40 with the flexible support member 34 both supports the flexible display assembly 30 and guides the flexible display assembly 30 as the second portion 14 moves to maintain smooth movement of the flexible display assembly 30.
Specifically, in the present embodiment, the limiting member 40 is a guiding gear, the limiting member 40 is disposed at a position corresponding to the first opening 1222, the middle portion of the flexible display screen assembly 30 is wound on the limiting member 40, and the first tooth portion 342 and the second tooth portion 42 on the flexible support 34 are engaged. That is, one end of the flexible display assembly 30 is fixedly coupled to the second portion 14 and the other end is coupled to the spool 20 through the first opening 1222 and around the limiter 40. When the second portion 14 drives one end of the flexible display screen 32 to move, the limiting member 40 is gradually rotated under the driving of the flexible supporting member 34, and the reel 20 gradually releases one end of the flexible supporting member 34.
It will be appreciated that in other embodiments, the limiter 40 may not be formed with the second teeth 42, but may be directly an optical axis or a roller, the flexible support 34 may not be formed with the first teeth 342, the limiter 40 and the flexible support 34 may be directly connected in a rolling manner, and the flexible display assembly 30 directly bypasses the roller, so that the limiter 40 can also support and guide the flexible display 32.

In this way, the light-transmitting portion 56 can protect the camera 60 without affecting the shooting effect of the camera 60, thereby preventing the camera 60 from being accidentally scratched due to direct exposure of the camera 60 to the outside of the housing 10. In this case, the camera 60 may be a rear camera of the mobile phone, and the rear camera may perform image capturing through the light-transmitting portion 56 on the cover 50. It will be appreciated that in some embodiments, the camera 60 may also be a front-facing camera of a mobile phone, in which case the camera 60 may be opened by forming an opening in the flexible display assembly 30 or forming an opening in the housing 10 for image acquisition, or may be a pop-up or slide-out mechanism, and when the front-facing camera is required, the camera 60 may be popped up or slid out of the housing 10 by the pop-up or slide-out mechanism, so as to increase the screen ratio of the electronic device 100.

Specifically, in such an embodiment, the second portion 14 is formed with a receiving space 140, the camera 60 is disposed in the receiving space 140, and light can be transmitted through the second portion 14 to be received by the camera 60 so that the camera 60 can perform image capturing through the second portion 60, and when the second portion 14 moves relative to the first portion 12, the camera 60 will also follow the second portion 14. In this way, the size of the display area 301 of the flexible display screen assembly 30 can be adjusted without affecting the photographing and image capturing functions of the camera 60, so that a user can take a photograph conveniently in any situation.
In such embodiments, the second portion 14 may further include a bottom panel 146, the bottom panel 146 being coupled to the second side panel 144, the bottom panel 146 and the second top panel 142 being disposed opposite and defining a receiving chamber 140 with the second top panel 142 and the second side panel 144, that is, the camera 60 may be disposed within the receiving chamber 140 between the second top panel 142 and the bottom panel 146, that is, the camera 30 may perform image acquisition through the bottom panel 146 of the second portion 14. Of course, it should be understood that the camera 60 may be only partially located in the accommodating chamber 140, so long as the camera 60 can perform normal shooting and photographing functions, which is not limited herein.

In this way, the camera 60 can receive light through the through hole (or the light transmitting region) and the light transmitting portion 56 for image acquisition.
Referring to fig. 13 and 15, when the electronic device 100 is in the narrow-screen mode, i.e. the first portion 12 and the second portion 14 move toward each other to the extreme positions, the first connecting portion 52 and the second connecting portion 54 are spliced together to form the cover 50 of the electronic device 100. Referring to fig. 14 and 16, the second connecting portion 54 is separated from the second connecting portion 52 when the second portion 14 moves away from the first portion 12 and when the second portion 14 moves from the first position a to the second position B.
Specifically, referring to fig. 13 and 14, in such an embodiment, the first connection portion 52 is formed with an arc-shaped recess 542, the second connection portion 54 is formed with a protrusion 522 matching the recess 542, and the protrusion 522 is also arc-shaped, when the electronic device 100 is in the narrow screen mode (as shown in fig. 13 and 15), the recess 542 and the protrusion 522 are spliced together to achieve the splicing of the first connection portion 52 and the second connection portion 54. It is understood that the first connecting portion 52 and the second connecting portion 54 may be made into other shapes, for example, both may be rectangular, and both may be directly spliced into the cover 50, for example, one of the two may be formed with regularly arranged protrusions, and the other may be formed with grooves corresponding to the protrusions, so that the shape of the housing 10 may be enriched to enhance the aesthetic feeling when the electronic device 100 is in the extended mode.
Further, in such an embodiment, the first connection part 52 and the second connection part 54 may be designed to have two different color effects, which may enrich the external appearance effect of the electronic device 100.
Referring to fig. 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 used for driving the second portion 14 to perform a separation motion relative to the first portion 12 to drive the flexible display assembly 30 to stretch.
In addition, referring to fig. 5 and 7, in an embodiment, the driving mechanism 70 may be further connected to the reel 20, and when the driving mechanism 70 drives the second portion 14 to move away from the first portion 12 (from the first position a to the second position B), the driving mechanism 70 may also simultaneously drive the reel 20 to rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen 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 to the second portion 14 and the motor 71, the second transmission structure 74 is connected to the first transmission structure 74 and the spool 20, and the motor 71 is configured to drive the second portion 14 to move relative to the first portion 12 via the first transmission structure 72 and to drive the spool 20 to rotate via 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 724. The first drive gear 722 is connected to the second drive structure 74 and is fixed to a motor shaft 711 of the motor 71, a rack 724 is fixedly connected to the second portion 14, and the rack 724 is meshed with the first drive gear 722. In this way, the gear and rack drive is adopted in the embodiment for driving, and the structure is simple, and the transmission is stable and reliable.
Specifically, in the present embodiment, the rack 724 is integrally formed with the second top plate 142 of the second portion 14, that is, the rack 724 may be directly integrally formed on the lower surface of the second top plate 142, so that the rack 724 may be directly formed on the second top plate 142, which has better integrity and is convenient to process. It will be appreciated that in other embodiments, the rack 724 may be formed separately from the second portion 14 and then fixedly attached thereto by welding or the like, although this is not a limitation.
Referring again to fig. 5 and 7, the second drive structure 74 connects the spool 20 and the first drive gear 722. The second transmission structure 74 includes a second transmission gear 742 and a third transmission gear 744, the second transmission gear 742 being fixed to the spool 20 and being disposed concentrically with the spool 20, the third transmission gear 744 being rotatably disposed on the first portion 12, and the third transmission gear 744 being connected to the second transmission gear 742 and the first transmission gear 722, i.e., the third transmission gear 744 being meshed with the second transmission gear 742 and the first transmission gear 722, respectively, the first transmission gear 722 and the second transmission gear 742 being located on opposite sides of the third transmission gear 744.
In this embodiment, the motor 71 may be used to drive the movement of the second portion 14 relative to the first portion 12 via the first transmission structure 72. At the same time, the motor 71 may also be used to drive the rotation of the spool 20 via the second transmission 74 to release the flexible display assembly 30 while simultaneously driving the second portion 14 in a spaced apart motion relative to the first portion 12. Thus, the flexible display assembly 30 is stretched and the reel 20 is released synchronously, so that the movement is stable, and the flexible display assembly 30 is not easy to wrinkle.
Specifically, when the display area of the electronic device 100, that is, the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the first transmission gear 722 may be driven by the motor 71 to rotate, and the first transmission gear 722 drives the second portion 14 to perform a separation motion with respect to the first portion 12 through the rack 724, that is, to move from the first position a to the second position B, and the second portion 14 drives the flexible display screen assembly 30 to stretch, that is, drives one end of the flexible display screen assembly 30 to perform a separation motion with respect to the first portion 12, and at the same time, the first transmission gear 722 may also simultaneously drive the third transmission gear 744 to rotate, and the third transmission gear 744 drives the scroll 20 to rotate, so that the scroll 20 can synchronously release the flexible display screen assembly 30, thereby achieving the purpose of expanding the display portion 301 of the flexible display screen assembly 30.
It will be appreciated that when it is desired to retract the display portion 301 of the flexible display assembly 30, i.e. the second position B, from the first position a, the motor 71 need only be reversed to move the second portion 14 in a direction opposite to the first portion 12, in which case the second portion 14 gradually releases the flexible display assembly 30 and the reel 20 is also able to gradually roll up the flexible display assembly 30. It will be appreciated that in this embodiment, the movement stroke of the second portion 14 is equal to the length of the flexible display assembly 30 released by rotation of the spool 20 per unit time. That is, by pulling one end of the flexible display assembly 30 at the second portion 14 by a certain distance, the roller 20 rotates to release a certain length, so that smooth movement of the flexible display assembly 30 can be ensured without wrinkling.
Furthermore, it is also understood that in some embodiments, in order to ensure the smoothness of the winding and releasing of the flexible display screen assembly 30 by the reel 20, the number of driving mechanisms 70 may be two, the number of the reels 20 may be two, and the two driving mechanisms 70 may be symmetrically disposed in the accommodating space 120 along the longitudinal direction of the electronic device 100 and connected to the second portions 14, respectively, and also connected to the two reels 20, respectively. In this way, a synchronized and smooth rotation of the two reels 20 and a smooth movement of the second portion 14 can be achieved by the synchronous driving of the two identical driving mechanisms 70, thereby ensuring the reliability of the movement of the electronic device 100 when expanding the display portion 301 of the flexible display assembly 30.
Still, in other embodiments, the drive mechanism 70 may also include two synchronous motors 71 disposed on the first portion 12, one motor 71 for driving the second portion 14 relative to the first portion 12, and the other motor 71 for driving the spool 20 in rotation, both driven by separate motors 71. In this way, the two motors 71 move synchronously, and the stability of the movement and the reliability of the movement of the flexible display screen assembly 30 can be ensured.
Further, in the present embodiment, the drive mechanism 70 drives the second portion 14 and the spool 20 by means of a gear transmission and a rack-and-pinion transmission. It will be appreciated that in other embodiments, the drive mechanism 70 may be configured to drive the second portion 14 and the spool 20 by a combination of belt and rack and pinion drive or a combination of chain and rack and pinion drive, for example, the first drive mechanism 72 may be configured to utilize a rack and pinion drive, and the second drive mechanism 74 may be configured to utilize a belt drive or a chain drive, as is specifically not limited herein.
In addition, in some embodiments, the driving mechanism 70 may also include only a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, where 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 return structure (not shown) coupled to the reel 20 for applying a force to the flexible display assembly 30 via the reel 20 to maintain the flexible display 32 in a rolled-up orientation on the reel 20.
In addition, referring to fig. 17, in some embodiments, the driving mechanism 70 may also include a motor disposed on the first portion 12 and a first transmission structure 72 connected to the motor, where the motor may drive the second portion 14 to move relative to the first portion 12 through the first transmission structure 72, and the second transmission structure 74 may be omitted.
Further, referring to fig. 17 to 20, in such an embodiment, the electronic device 100 may further include a restoring mechanism 80, where the restoring mechanism 80 may also be disposed in the accommodating space 120, the restoring mechanism 80 is connected to the first reel 20, and the restoring mechanism 20 is used for applying a restoring force to the flexible display assembly 30 to keep the flexible display assembly 30 in a tendency to be rolled up on the first reel 20.
Specifically, the return mechanism 80 applies a return force to the first roller 20, and the first roller 20 maintains the tendency of the flexible display screen assembly 30 to roll up on the first roller 20 under the force of the return force. That is, when the second portion 14 is not moved relative to the first portion 12 by the external force, the restoring force of the restoring mechanism 80 rotates the first roller 20, so that the one end of the flexible display screen assembly 30 is rolled up on the first roller 20, and in this case, the first portion 12 and the second portion 14 are completely engaged, and the electronic device 100 is in the narrow screen mode.
When the second portion 14 is subjected to an external force and the external force (e.g., the force applied to the second portion 14 by the driving mechanism 70) is greater than or equal to the restoring force of the restoring mechanism 80, the second portion 14 moves away from the first portion 12, i.e., from the first position a to the second position B, so as to drive the first reel 20 to rotate against the restoring force to release the flexible display assembly 30, thereby expanding the display portion 301 of the flexible display assembly 30.
It will be appreciated that due to the presence of the return mechanism 80, the return mechanism 80 will always apply tension to the flexible display assembly 30 during expansion of the display portion 301 of the display layer 32, thereby allowing the flexible display to be balanced, i.e., allowing the flexible display assembly 30 to remain flat at all times.
It will also be appreciated that in other embodiments, where the electronic device 100 includes the return mechanism 80, the drive mechanism 70 may also include the motor, the first transmission structure 72, and the second transmission structure 74 of the above embodiments, the first transmission structure 72 being coupled to the second portion 12 of the motor, and the second transmission structure 74 being coupled to the first transmission structure 72 and the first spool 20. In such an embodiment, when it is desired to reduce the display area 301, the motor may not be operated, but rather the restoring force of the restoring mechanism 80 may be used to reverse the first reel 20 to wind up the flexible display assembly 30 and move the second portion 14 toward each other with respect to the first portion 12, i.e., toward the first portion 12.
Further, referring to fig. 18, the restoring mechanism 80 may include an elastic element connected to the first reel 20 and configured to apply a restoring force to the first reel 20. The elastic element may be a spring, such as a torsion spring as shown in fig. 18, or the like. Of course, the elastic element may be an element having elastic restoring force such as rubber, and is not limited herein.
In further referring to fig. 19, in such an embodiment, the electronic device 100 may further include a detent structure 90, where the detent structure 90 is disposed on the housing 10, and the detent structure 90 is configured to limit rotation of the first reel 20 when the second portion 14 moves to a predetermined position relative to the first portion 12. That is, the detent structure 90 may prevent the second portion 14 and the flexible display assembly 30 from retracting under the restoring force of the restoring mechanism 80 when the second portion 14 moves to a predetermined position relative to the first portion 12.
Specifically, referring to fig. 19, in the present embodiment, the latch structure 90 may include a latch 92 formed on the first portion 12 and a latch 94 formed on the second portion 14, and when the second portion 14 moves to a predetermined position relative to the first portion 12, the latch 92 is engaged in the latch 94. Thus, even if the external force to the second portion 14 is removed, the second portion 14 and the flexible display assembly 30 will not retract under the restoring force of the restoring mechanism 80 due to the engagement of the latch 92 and the latch groove 94. To ensure that the electronic device 100 is in the expanded mode.
It should be noted that, the "preset position" may be a relative position between the second portion 14 and the first portion 12 when the second portion moves away from the first portion to the limit position, or may be any position before the limit position.
It will be appreciated that referring to fig. 20, in other embodiments, a clamping groove 94 may be formed in the first portion 12, and a clamping block 92 may be formed in the second portion 14. In addition, in some embodiments, a latch may be formed on the first portion 12, a slot is formed on the first reel 20, and when the second portion 14 moves to the preset position, the latch is engaged with the slot, in which case, the latch and the slot may be manually pressed or electrically driven to engage, so that the reel will not rotate relative to the first portion, and the second portion 14 and the flexible display screen assembly 30 will not retract under the action of the restoring mechanism 80. Of course, in other embodiments, the detent structure 90 may also include a catch, and the return mechanism 80 includes a torsion spring, which the catch may catch when the second portion 14 moves to the predetermined position to counteract the return force of the torsion spring. Additionally, it is also understood that in some embodiments, the detent structure 90 may also include a resilient assembly disposed on the first portion 12 and a first catch formed on the second portion 14, the resilient assembly may include a pressing member mounted on the first portion 12, a spring connecting the pressing member and the second catch, and a second catch formed on the second portion 14, the pressing member being operable to move the second catch under the force of an external force through the spring to engage the first catch, thereby defining the relative positions of the first portion 12 and the second portion 14. Thus, when the second portion 14 moves to the preset position, the user can press the pressing member to make the first fastening portion and the second fastening portion fasten, so as to prevent the second portion 14 from retracting under the action of the restoring force of the restoring mechanism 80, and keep the electronic device 100 in the extended mode. It will be appreciated that upon re-pressing the press, the first and second catches separate, thereby enabling the second portion 14 and the flexible display assembly 30 to retract under the influence of the return mechanism 80 to return the electronic device 100 from the expanded mode to the narrow screen mode.
The electronic device 100 of the present embodiment operates as follows:
referring to fig. 4 to 7, as described above, the electronic device 100 can switch between the narrow-screen mode and the extended mode. In the state shown in fig. 4 and 5, the electronic device 100 is in the narrow screen mode, and in the state shown in fig. 6 and 7, the electronic device 100 is in the expansion mode. When in the narrow screen mode, the first portion 12 and the second portion 14 cooperate to form the housing 10, one end of the flexible display screen assembly 30 is wound on the reel 20, and the other end is connected to the second portion 14, at this time, only a smaller portion of the flexible display screen assembly 30 is exposed from the housing 10, and the display portion 301 is narrower, so that the flexible display screen assembly can be carried by a user conveniently.
When a user needs a larger display portion 301, the driving mechanism 70 may drive the second portion 14 to perform a separation motion with respect to 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 a portion of the flexible display screen assembly 30 hidden in the housing 10 is gradually pulled out by the second portion 14 (i.e. 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 may be convenient for the user to operate to improve the operation experience of the user.
When the expansion mode is required to be switched to the narrow screen mode, the motor 71 of the driving mechanism 70 is only required to be reversed to drive the second portion 14 to move in opposite directions relative to the first portion 12, so that the flexible display screen assembly 30 is released, at the moment, the reel 20 is correspondingly reversed to synchronously roll up the flexible display screen assembly 30, and when the flexible display screen assembly moves to the limit position of opposite movement between the first portion 12 and the second portion 14, the motor 71 stops running, and the electronic device 100 returns to the narrow screen mode.
Referring to fig. 21 to 24, in some embodiments of the present application, when the second portion 14 is located at the second position B, the housing 10 exposes the cavity 110, and the cavity 110 can be used for the external functional component 200 to be placed in order to connect the external functional component 200 with the electronic device 100.
In such an embodiment, as the second portion 14 moves from the first position a to the second position B, the second portion 14 stretches the flexible display assembly 30 to expand the display portion 301 of the flexible display assembly 30, while the housing 10 exposes the cavity 110 when the second portion 14 is in the second position B, thereby enabling the cavity 110 to house the external function assembly 200. In this way, after expanding the display portion 301 of the flexible display screen assembly 30, the user may place the external functional assembly 200 into the cavity 110 to connect with the electronic device 100, so as to improve the usability of the electronic device 100 to improve the user experience, for example, the external battery assembly may be placed into the cavity 110 to improve the cruising ability of the electronic device 100.
In some embodiments, the external functional component 200 includes at least one of an external battery component, a speaker component, a key component, a light component, and a camera component.
In this manner, the external battery assembly, speaker assembly, key assembly, light assembly, and camera assembly may be built into the cavity 110 to enhance the usability of the electronic device 100.
Specifically, referring to fig. 22 and 23, when the second portion 14 is located at the second position B, the electronic device 100 is in the extended mode, and at this time, the display portion 301 of the flexible display screen assembly 30 has the largest area, so as to increase the power consumption of the electronic device 100, and when the external functional assembly 200 is an external battery assembly, the external battery assembly can serve as an external power source of the electronic device 100, so as to improve the cruising ability of the electronic device 100. In addition, when the second portion 14 is at the second position B, the volume of the electronic device 100 is also the largest, and at this time, the audio of the electronic device 100 is still the original self-contained audio, and the audio cavity is too small compared to the volume of the electronic device 100 after expansion, so that a better stereo effect cannot be achieved. In such a case, placing the speaker assembly into the cavity 110 may increase the overall sound cavity experience, bring about a larger and better 3D surround sound experience, and promote the user experience. In addition, when the second portion 14 is in the second position B, the electronic device 100 has a larger size, which may cause inconvenience to the user in using the key assembly, in which case, the key assembly may be placed in the cavity 110, and the key assembly may provide more operation space for the electronic device 100, so that the user may better control the electronic device 100.
