The electronic device and the electronic device provided by the embodiment of the present application are described in detail below with reference to fig. 1 to 7 through specific embodiments and application scenarios thereof.

The electronic device disclosed by the embodiment of the invention comprises a first shell 100, a second shell 200, a scroll 300, a first driving mechanism 400 and a flexible screen 700. The first and

second housings

100 and 200 are basic structural members that provide a mounting base for the roller 300, the first driving mechanism, and/or the flexible screen 700.

The reel 300 is rotatably disposed on the first casing 100, the first casing 100 and the second casing 200 are slidably engaged, and the first driving mechanism 400 is used for driving the second casing 200 to move relative to the first casing 100. The reel 300 may be disposed at a first side of the first casing 100, and the second casing 200 may be movable along the first casing 100 toward a second side of the first casing 100, and the first side of the first casing 100 may be opposite to the second side of the first casing 100. A first section of flexible screen 700 is attached to second housing 200, a second section of flexible screen 700 is a sliding fit with first housing 100, and flexible screen 700 is retractable into first housing 100 and/or spool 300. Specifically, in the case where the second casing 200 is moved in a direction away from the first casing 100, the flexible screen 700 is gradually unfolded. In the case where the second housing 200 is moved to a direction close to the first housing 100, the flexible screen 700 is gradually contracted to the first housing 100 and/or the reel 300.

Optionally, one of the first casing 100 and the second casing 200 is provided with a sliding groove, the other is provided with a sliding rail adapted to the sliding groove, and the first casing 100 and the second casing 200 are in sliding fit with each other through the sliding groove and the sliding rail. Optionally, the second housing 200 is provided with a "T" shaped groove, and the first housing 100 is provided with a "T" shaped guide rail to increase the stability of the sliding fit of the first housing 100 and the second housing 200.

Referring to fig. 3 to 5, the first driving mechanism 400 may include a telescopic hinge 410, a linkage shaft 420, and a power member 430, the linkage shaft 420 is disposed in the first housing 100, a first end of the telescopic hinge 410 is connected to the second housing 200, a second end of the telescopic hinge 410 is provided with a first leg 411 and a second leg 412, the first leg 411 and the second leg 412 are both connected to the linkage shaft 420, and the power member 430 is configured to drive the first leg 411 and the second leg 412 to approach or move away from each other along the linkage shaft 420. Under the condition that the first supporting leg 411 and the second supporting leg 412 are close to each other along the linkage shaft 420, the telescopic hinge 410 extends and drives the second casing 200 to move in the direction away from the first casing 100, so that the flexible screen 700 is gradually unfolded, and the purpose of increasing the display area of the electronic device is achieved. Under the condition that the first supporting leg 411 and the second supporting leg 412 are far away from each other along the linkage shaft 420, the telescopic hinge 410 is shortened and drives the second casing 200 to move towards the direction close to the first casing 100, so that the flexible screen 700 is gradually contracted to the first casing 100 and/or the scroll 300, and the purpose of reducing the display area of the electronic device is achieved.

In the above embodiment, the telescopic hinge 410 can be driven by the linkage shaft 420 to be telescopic in a stepless manner, that is, the telescopic hinge 410 can be adjusted to any value within the telescopic range under the action of the linkage shaft 420, so that the electronic device can realize stepless adjustment of the size of the display area within the range that the display area can be widened, and is further suitable for diversified demands of users. Moreover, the overall structure of the telescopic hinge 410 is a flat device, which not only increases the supporting area of the flexible screen 700, but also is beneficial to the light and thin design of the electronic device. Optionally, the linkage rod forming the telescopic hinge 410 is a sheet-shaped link rod.

The telescopic hinge 410 is of many kinds, for example: scissors fork type hinges, diamond telescopic hinges, link mechanisms and the like. The present invention is not limited to a particular type of telescoping hinge 410.

Referring to fig. 3 to 5, the linkage shaft 420 may include a first thread section 421 and a second thread section 422, the first leg 411 is provided with a first thread bush 4111, the second leg 412 is provided with a second thread bush 4121, the first thread bush 4111 is engaged with the first thread section 421, the second thread bush 4121 is engaged with the second thread section 422, and the thread direction of the first thread section 421 is opposite to that of the second thread section 422. The thread directions of the first thread section 421 and the second thread section 422 on the linkage shaft 420 are opposite, so as to drive the first thread sleeve 4111 and the second thread sleeve 4121 to synchronously approach or synchronously depart from each other along the linkage shaft 420, thereby ensuring that the acting force acting on the second housing 200 always moves along the direction of the second housing 200 relative to the first housing 100, and preventing the second housing 200 and the first housing 100 from being stuck.

Referring to fig. 3 to 5, the linkage shaft 420 may be provided with a first gear 423, the reel 300 may be provided with a second gear 310, the first gear 423 and the second gear 310 are engaged, and the linkage shaft 420 may drive the reel 300 to rotate through the first gear 423 and the second gear 310. The linkage shaft 420 not only can provide power for the second casing 200 to move relative to the first casing 100, but also can realize the rotation of the reel 300 through the meshing transmission of the first gear 423 and the second gear 310, so as to realize the synchronous movement of the second casing 200 relative to the first casing 100 and the rotation of the reel 300 relative to the first casing 100, that is, under the condition that the second casing 200 is far away from the first casing 100, the linkage shaft 420 can drive the reel 420, and the reel 420 is utilized to drive the second section of the flexible screen 700 to be unfolded to one side where the first section of the flexible screen 700 is located, under the condition that the second casing 200 is close to the first casing 100, the linkage shaft 420 can drive the reel 300, and the reel 300 is utilized to drive the second section of the flexible screen 700 to be contracted to the reel 300 and/or the first casing 100. Further, the transmission ratio between the linkage shaft 420 and the reel 300 can be adjusted, so that the linear speed of the flexible screen 700 along the surface of the reel 300 is equal to the moving speed of the second housing 200 relative to the first housing 100, and further, the tension on the flexible screen 700 can be reduced while the flexible screen 700 is prevented from being wrinkled.

Referring to fig. 4, the power member 430 may include a driving motor 431 and a reduction gearbox 432, the reduction gearbox 432 having a power input shaft and a power output shaft, the driving motor 431 being connected to the power input shaft, and the power output shaft being connected to the linkage shaft 420. The output speed of the drive motor 431 is relatively high, typically 1000 to 1500 revolutions per minute. If the driving motor 431 is directly connected to the linkage shaft 420, the driving motor 431 is damaged due to excessive force at the moment of starting. In the above scheme, the reduction gearbox 432 not only can reduce the output rotation speed of the power member 430, and prevent the flexible screen 700 from being damaged due to overload caused by the fact that the second casing 200 moves too fast relative to the first casing 100, but also can improve the bearing capacity of the driving motor 431.

The reduction gearbox 432 can be of many types, such as a gear box, planetary gear, etc. Therefore, the present application does not limit the specific kind of the reduction gearbox 432.

Referring to fig. 3 to 5, the electronic device may further include a second driving mechanism 500, the second driving mechanism 500 is disposed at two ends of the reel 300, and the second driving mechanism 500 may drive the reel 300 to rotate relative to the first housing 100, so as to drive the flexible screen 700 to expand or contract, and further drive the flexible screen 700 through the second driving mechanism 500, so that the flexible screen 700 may be in a tensioned state, so as to maintain the flatness of the flexible screen 700. Further, the reel 300 has mounting spaces at both ends thereof, and the second driving mechanism 500 is disposed in the mounting spaces, so as to reduce the occupation of the internal space of the electronic device by the second driving mechanism 500.

There are many kinds of the second driving mechanism 500, for example, a driving motor, a coil spring, a ring-shaped piezoelectric ceramic plate, etc., and the present application does not limit the specific kind of the second driving mechanism 500.

Referring to fig. 6, a second segment of flexible screen 700 may be connected to spool 300, and the second segment of flexible screen 700 may be wound around spool 300. Specifically, one end of the second section of the flexible screen 700, which is far away from the first section, is fixedly connected to the scroll 300, so that the scroll 300 can drive the second section of the flexible screen 700 to be wound on the scroll 300, thereby enabling the flexible screen 700 to be contracted on the scroll 300. Specifically, in the case that the second casing 200 is far from the first casing 100, the second segment of the flexible screen 700 extends from the surface of the scroll 300 to the surface of the first casing 100, so that the flexible screen 700 can be unfolded, thereby increasing the display area of the electronic device. Under the condition that the second casing 200 is close to the first casing 100, the second segment of the flexible screen 700 may be wound around the scroll 300 along the surface of the scroll 300, so that the flexible screen 700 may be contracted to the scroll 300, thereby reducing the display area of the electronic device.

A second segment of flexible screen 700 may be bent along the surface of spool 300 and flexible screen 700 may be slid along the surface of first housing 100. Under the condition that the second casing 200 moves in the direction away from the first casing 100, the second section of the flexible screen 700 slides from the first side of the first casing 100 to the second side of the first casing 100, so that the second section of the flexible screen 700 is unfolded, thereby increasing the display area of the electronic device. Under the condition that the second casing 200 moves in the direction close to the first casing 100, the second segment of the flexible screen 700 slides from the second side of the first casing 100 to the first side of the first casing 100 along the scroll 300, so that the flexible screen 700 is retracted into the first casing 100, thereby reducing the display area of the electronic device. This scheme can avoid flexible layer 700 transition bending, and then can further reduce the pulling force that flexible screen 700 received in the expansion or shrink process. Further, an end of the second segment of the flexible screen 700, which is away from the first segment, may be connected to the first housing 100 by an elastic member, so that the flexible screen 700 may be maintained in a tensioned state by pulling the flexible screen 700 by the elastic member.

Referring to fig. 5 to 7, the electronic device may further include a screen supporter 600, the screen supporter 600 supporting the flexible screen 700. The screen support 600 may be disposed between the telescopic hinge 410 and the flexible screen 700 to support the screen support 600 through the telescopic hinge 410, so that the screen support 600 can provide a greater supporting force for the flexible screen 700. One end of the screen support 600 is connected to the first casing 100, and the second end of the screen support 600 is connected to the second casing 200, and the second casing 200 can drive the screen support 600 to unfold or fold. Specifically, under the condition that the second housing 200 moves in the direction away from the first housing 100, the second housing 200 drives the screen supporting member 600 to unfold the screen supporting member 600, so as to increase the area of the supporting surface of the screen supporting member 600 for supporting the flexible screen 700, and prevent the flexible screen 700 from collapsing after being stressed.

Referring to fig. 6 and 7, the screen supporter 600 includes a plurality of support blocks 610, the support blocks 610 are disposed at the first casing 100 and/or the second casing 200, and the support blocks 610 may slide along the first casing 100 and/or the second casing 200, two adjacent support blocks 610 are rotatably connected, and two adjacent support blocks 610 may be unfolded or folded along the connection. The support block 610 is elongated, and the support block 610 may span the first and

second housings

100 and 200 such that both ends of the support block 610 may be supported by the first and/or

second housings

100 and 200.

There are many ways in which two adjacent support blocks 610 may be pivotally connected, such as a hinged, foldable flap, and the application is not limited to the particular way in which adjacent support blocks 610 are pivotally connected.

In an alternative embodiment, the screen support 600 further comprises an elastic constriction 620. Referring to fig. 7, the elastic shrinkage member 620 is used to connect two adjacent support blocks 610, so that the two adjacent support blocks 610 are folded by the elastic shrinkage member 620. Optionally, the two adjacent support blocks 610 are a first support block and a second support block, the first side of the first support block is rotatably connected to the first side of the second support block, the second side of the first support block is connected to the second side of the second support block through an elastic shrinking member 620, and the elastic shrinking member 620 can drive the first support block and the second support block to be folded. The first side of the first supporting block is opposite to the second side of the first supporting block; the first side of the second support block is opposite to the second side of the second support block. The elastic contraction member 620 may be an elastic string, an elastic film, a spring plate, or the like, and the specific structure of the elastic contraction member 620 is not limited in this application.

In the above embodiment, the elastic contraction member 620 may enable the plurality of support blocks 610 to be synchronously unfolded or folded, so that the support points of the screen support 600 supporting the flexible screen 700 may be uniformly distributed below the flexible screen 700, and the screen support 600 may provide a uniform support force for the flexible screen 700. It should be noted that although there is a gap between the supporting points of the flexible screen 700 supported by the adjacent two supporting blocks 610 in the folded state of the supporting blocks 610, the gap between the supporting points may not be perceived by the user by setting the width of the supporting blocks 610 such that the distance between the supporting points of the flexible screen 700 supported by the adjacent two supporting blocks 610 is reduced. Alternatively, the elastic shrinkage member 620 may be an elastic film, and when the support blocks 610 are in the folded state, the elastic shrinkage member 620 shrinks and is tensioned between the support points of the two adjacent support blocks 610 supporting the flexible screen 700 through self-deformation, so as to form an elastic support between the two adjacent support blocks 610, thereby preventing the flexible screen 700 from being recessed in the gap between the two support blocks 610.

The screen supporter 600 may also be a memory metal, and changing the voltage across the screen supporter 600 controls the unfolding or folding of the screen supporter 600.
