Because the both ends of flexible screen 10 are provided with first flexible rack 11 respectively, second flexible rack 12, first end plate 20 rotates with first gear 21 to be connected, second end plate 30 rotates with second gear 31 to be connected, first gear 21 meshes with first flexible rack 11, second gear 31 meshes with second flexible rack 12, therefore, when telescopic bracket 40 extends, telescopic bracket 40 can make first end plate 20 keep away from each other with second end plate 30, and then make flexible screen 10 expand, when telescopic bracket 40 contracts, telescopic bracket 40 can make first end plate 20 be close to each other with second end plate 30, and then make flexible screen 10 draw in. That is, in the embodiment of the present application, the two ends of the flexible screen 10 are connected to the first end plate 20 and the second end plate 30 through the first flexible rack 11, the first gear 21, the second flexible rack 12 and the second gear 31, respectively, and the first end of the telescopic bracket 40 is connected to the first end plate 20, and the second end of the telescopic bracket 40 is connected to the second end plate 30 through the driving structure 50, so that when the driving structure 50 drives the telescopic bracket 40 to extend and retract, the first end plate 20 and the second end plate 30 can be away from or close to each other, so that the flexible screen 10 is unfolded or folded, further, the display area of the flexible screen 10 is changed, and the flexible screen 10 is prevented from being folded, therefore, the possibility of failure of the flexible screen 10 can be reduced, and the service life of the flexible screen 10 is prolonged.
In addition, in the embodiment of the present application, the first end of the telescopic bracket 40 may be connected to the first end plate 20 by: as shown in fig. 9 or 10, a support 22 may be disposed on the first end plate 20, and a first end of the telescopic bracket 40 is fixedly connected to the first end plate 20 through the support 22, that is, by disposing the support 22 on the first end plate 20, a first end of the telescopic bracket 40 is connected to the support 22, so that the first end of the telescopic bracket 40 is connected to the first end plate 20.
When the support 22 is arranged on the first end plate 20 and the first end of the telescopic bracket 40 is connected with the support 22, at this time, the first end of the telescopic bracket 40 can be conveniently connected with the first end plate 20, so that the connection between the first end of the telescopic bracket 40 and the first end plate 20 is convenient.
It should be noted that the first end of the telescopic bracket 40 may be connected to the support 22 in a hinged manner, and of course, other connection manners, such as riveting, may also be used, and the embodiment of the present invention is not limited herein.
In addition, in the embodiment of the present application, when the first gear 21 is rotatably connected to the first end plate 20, the second gear 31 is rotatably connected to the second end plate 30, the first gear 21 is engaged with the first flexible rack 11 at the first end of the flexible screen 10, and the second gear 31 is engaged with the second flexible rack 12 at the second end of the flexible screen 10, when the telescopic bracket 40 is extended, the telescopic bracket 40 makes the first end plate 20 and the driving structure 50 be away from each other, and further makes the first end plate 20 and the second end plate 30 be away from each other. During the process of moving the first end plate 20 and the second end plate 30 away from each other, the first end plate 20 may apply a force to the first gear 21 so that the first gear 21 rotates, and the second end plate 30 may apply a force to the second gear 31 so that the second gear 31 rotates. After the first gear 21 and the second gear 31 rotate, the first gear 21 drives the first flexible rack 11 to move, so that the first end of the flexible screen 10 moves, and the second gear 31 drives the second flexible rack 12 to move, so that the second end of the flexible screen 10 moves, and the flexible screen 10 is unfolded. As the telescoping support 40 is retracted, the telescoping support 40 causes the first end plate 20 and the drive structure 50 to move closer together, thereby moving the first end plate 20 and the second end plate 30 closer together. During the process of the first and second end plates 20 and 30 approaching each other, the first end plate 20 may apply a force to the first gear 21 so that the first gear 21 rotates, and the second end plate 30 may apply a force to the second gear 31 so that the second gear 31 rotates. After the first gear 21 and the second gear 31 rotate, the first gear 21 drives the first flexible rack 11 to move, so that the first end of the flexible screen 10 moves, and the second gear 31 drives the second flexible rack 12 to move, so that the second end of the flexible screen 10 moves, and the flexible screen 10 is folded.
That is, the first gear 21 is disposed on the first end plate 20, the second gear 31 is disposed on the first end plate 20, the first flexible rack 11 is disposed at the first end of the flexible screen 10, the second flexible rack 12 is disposed at the second end of the flexible screen 10, the first gear 21 is engaged with the first flexible rack 11, and the second gear 31 is engaged with the second flexible rack 12, so that the flexible screen 10 is driven to unfold or fold when the first end plate 20 and the second end plate 30 are away from or close to each other.
It should be noted that the first flexible rack 11 may be disposed at the first end of the flexible panel 10 by an adhesion manner, and the second flexible rack 12 may also be disposed at the second end of the flexible panel 10 by an adhesion manner, of course, the first flexible panel 10 may also be disposed at the first end of the flexible panel 10 by another manner, and the second flexible rack 12 may also be disposed at the second end of the flexible panel 10 by another manner, which is not limited herein.
In addition, in the embodiment of the present application, the number of the first gears 21 and the number of the second gears 31 can be set according to actual requirements, for example, the number of the first gears 21 can be two, and the number of the second gears 31 can be two, and the embodiment of the present application is not limited herein for the number of the first gears 21 and the number of the second gears 31. In addition, the number of the first flexible racks 11 may be the same as the number of the first gears 21, and the number of the second flexible racks 12 may be the same as the number of the second gears 31.
In addition, in the embodiment of the present application, a first rotating shaft is disposed on the first end plate 20, and the first gear 21 is sleeved on the first rotating shaft, so that the first gear 21 is rotatably connected to the first end plate 20. Similarly, a second rotating shaft may be disposed on the second end plate 30, and the second gear 31 is sleeved on the second rotating shaft, so that the second gear 31 is rotatably connected to the second end plate 30.
In addition, in the embodiment of the present application, the telescopic bracket 40 may have different forms, and specifically, the following are taken as examples:
(1) as shown in fig. 5, the telescopic bracket 40 may include a hinge assembly 41, and the hinge assembly 41 includes a plurality of links 411 arranged in sequence. Two adjacent links 411 are hinged by a first hinge axis, at least one link 411 being connected to the driving structure 50.
When the telescopic bracket 40 includes the hinge assembly 41, the hinge assembly 41 includes a plurality of links 411 arranged in sequence, and at least one link 411 is connected to the driving structure 50, the driving structure 50 may drive the link 411 connected to the driving structure 50 to move. Since two adjacent links 411 are hinged by the first hinge shaft, after the driving structure 50 drives the link 411 connected to the driving structure 50 to move, the link 411 can drive the other links 411 to move, so that the form of the hinge assembly 41 changes, that is, the hinge assembly 41 extends or contracts, so that the telescopic bracket 40 extends or contracts.
(2) As shown in fig. 7, the telescopic bracket 40 may include two sets of hinge assemblies 41. The middle point of the link 411 of the first set of hinge members 41 is hinged to the middle point of the link 411 of the second set of hinge members 41, and the link 411 at one end of the first set of hinge members 41 is hinged to the driving structure 50.
When the connecting rod 411 at one end of the first set of hinge assemblies 41 is connected to the driving structure 50, the driving structure 50 can drive the connecting rod 411 connected to the driving structure 50 to move, so that the state of the first set of hinge assemblies 41 is changed. Since the middle point of the connecting rod 411 of the first set of hinge assemblies 41 is hinged to the middle point of the connecting rod 411 of the second set of hinge assemblies 41, when the state of the first set of hinge assemblies 41 changes after the driving structure 50 drives the connecting rod 411 connected to the driving structure 50 to move, the first hinge assemblies 41 can drive the second set of hinge assemblies 41 to correspondingly change the state of the second set of hinge assemblies 41, that is, the first hinge assemblies 41 and the second hinge assemblies 41 simultaneously extend or retract, so that the telescopic bracket 40 extends or retracts. In addition, through setting up two sets of articulated components 41, can also make telescopic bracket 40 at the flexible in-process, telescopic bracket 40's stability is better.
In the above mode (1), the telescopic bracket 40 includes a set of hinge assemblies 41, so that the telescopic bracket 40 can be extended and retracted, thereby saving the hinge assemblies 41 and reducing the cost of the electronic device. In the above mode (2), the telescopic bracket 40 includes two sets of hinge assemblies 41 to extend and retract the telescopic bracket 40, so that the stability of the telescopic bracket 40 is good.
In addition, in some embodiments, as shown in fig. 7 and 8, the electronic device may further include a transmission structure 60, the driving structure 50 is connected to the transmission structure 60, and the transmission structure 60 includes a first guide post 61, a second guide post 62, a first slider 63, and a second slider 64. The first guide post 61 is connected with the second guide post 62, the first sliding block 63 is sleeved on the first guide post 61, the second sliding block 64 is sleeved on the second guide post 62, the first sliding block 63 is connected with the second sliding block 64 through a connecting rod, the first sliding block 63 is hinged with the telescopic bracket 40, and the second sliding block 64 is connected with the driving structure 50. The driving structure 50 is configured to drive the second sliding block 64 to slide on the second guide post 62, so that the first sliding block 63 slides on the first guide post 61 to drive the telescopic bracket 40 to extend and retract.
Since the first sliding block 63 is sleeved on the first guide post 61, the first sliding block 63 can slide along the first guide post 61. Because the second sliding block 64 is sleeved on the second guide post 62, the second sliding block 64 can slide along the second guide post 62. Because the first sliding block 63 is connected with the second sliding block 64 through the connecting rod, the first sliding block 63 is hinged with the telescopic bracket 40, and the second sliding block 64 is connected with the driving structure 50, the driving structure 50 can drive the second sliding block 64 to slide along the second guide post 62, the second sliding block 64 drives the first sliding block 63 to slide along the first guide post 61, and the first sliding block 63 drives the telescopic bracket 40 to stretch and retract. In the process of extending and retracting the telescopic bracket 40, the telescopic bracket 40 applies a force to the first guide post 61 through the first slider 63, so that the first guide post 61 applies a force to the driving structure 50 through the second slider 64, and further the driving structure 50 applies a force to the second end plate 30, so that the second end plate 30 moves.
Specifically, when the driving member drives the second slider 64 to slide on the second guide post 62 along the first direction, the second slider 64 drives the first slider 63 to move along the first guide post 61, the first slider 63 drives the telescopic bracket 40 to extend, and when the driving member drives the second slider 64 to slide on the second guide post 62 along the second direction, the second slider 64 drives the first slider 63 to move along the first guide post 61, and the first slider 63 drives the telescopic bracket 40 to retract. Wherein the first direction and the second direction are opposite.
It should be noted that, in the embodiment of the present application, the driving structure 50 may be a motor, and of course, the driving structure 50 may also be other devices, such as an electric motor, for example, and the embodiment of the present application is not limited herein.

With the flexible screen 10 in the unfolded state, the filling assembly 70 moves between the first and second end plates 20, 30 to fill the gap between the first and second end plates 20, 30.
When the electronic device includes the mounting assembly 100 and the movable filling assembly 70, when the filling assembly 70 is connected to the mounting assembly 100, when the telescopic bracket 40 drives the first end plate 20 and the second end plate 30 to be away from each other, that is, under the condition that the flexible screen 10 is in the unfolded state, a gap is generated between the first end plate 20 and the second end plate 30, at this time, the filling assembly 70 can be moved to between the first end plate 20 and the second end plate 30, the gap between the first end plate 20 and the second end plate 30 is filled through the filling assembly 70, and the surface of the electronic device can be relatively flat.
It should be noted that, when the first end plate 20 and the second end plate 30 are far away from each other and the distance between the first end plate 20 and the second end plate 30 reaches the maximum distance, at this time, the first end plate 20 and the second end plate 30 cannot be further far away from each other, and the filling assembly 70 fills the gap between the first end plate 20 and the second end plate 30.
