A flexible screen device according to an embodiment of the present application is described below with reference to fig. 1-10.

As shown in fig. 1-5, a flexible screen apparatus according to some embodiments of the present application, the flexible screen apparatus comprising:

the device comprises a device body and a flexible screen 5 arranged on the device body;

the supporting component is arranged on the equipment main body and comprises a first supporting plate 21, a second supporting plate 22 and a third supporting plate 23;

the first support plate 21 has a first surface 210; the second support plate 22 has a second surface 220, and the first surface 210 and the second surface 220 are in the same plane; the third support plate 23 has a third surface 230.

A driving assembly capable of driving the supporting assembly to switch between a first state and a second state;

when the support assembly is in the first state, the flexible screen 5 is in the first unfolded state, the first support plate 21 is disposed adjacent to the second support plate 22, and the first surface 210 and the second surface 220 form a support surface for supporting the flexible screen 5.

When the support assembly is in the second state, the flexible screen 5 is in the second unfolded state, the unfolded area of the first unfolded state is larger than the unfolded area of the first unfolded state, the first support plate 21 and the second support plate 22 are far away, the third support plate 23 is located at a position between the first support plate 21 and the second support plate 22, the first surface 210, the second surface 220 and the third surface 230 are located in the same plane, and the first surface 210, the second surface 220 and the third surface 230 form a support surface for supporting the flexible screen 5. For example, the first unfolded state and the second unfolded state of the flexible screen 5 are two different unfolded positions of the flexible screen 5. When the flexible screen 5 is adjusted from the first unfolded state to the second unfolded state, the flexible screen 5 is unfolded, and the area of the flexible screen 5 is increased. When the flexible screen 5 is adjusted from the second unfolded state to the first unfolded state, the flexible screen 5 is contracted, and the area of the flexible screen 5 is reduced.

In the embodiment of the present application, when the flexible screen 5 is unfolded, the first support plate 21 is far away from the second support plate 22, and the third support plate 23 provides support at a position between the first support plate 21 and the second support plate 22 through the second state of the support assembly, so that the first surface 210, the second surface 220, and the third surface 230 form a support surface for supporting the flexible screen 5, which can improve the support effect of the support assembly on the flexible screen 5 after the flexible screen 5 is unfolded.

In an embodiment of the present application, the apparatus body may include a first body 11 and a second body 12, and the first body 11 and the second body 12 are relatively slidable. For example, the first body 11 is provided with a latch 111, the second body 12 is provided with a latch groove 121, and the latch 111 is slidably engaged with the latch groove 121.

During the unfolding process of the flexible screen device, the first body 11 is far away from the second body 12, and the first support plate 21 is far away from the second support plate 22. When the support assembly is in the first state, the first support plate 21 and the second support plate 22 are far away, and the third support plate 23 is moved between the first support plate 21 and the second support plate 22, so that the first surface 210, the second surface 220 and the third surface 230 are in the same plane, thereby forming a support surface for supporting the flexible screen 5.

The third supporting plate 23 is located between the first supporting plate 21 and the second supporting plate 22, and supports the overhead position of the flexible screen 5 between the first supporting plate 21 and the second supporting plate 22, so that the overhead position is reduced, and the problem of insufficient support of the flexible screen 5 is avoided.

During the process of storing the flexible screen device, the first body 11 approaches the second body 12, and the third support plate 23 is separated from the position between the first support plate 21 and the second support plate 22. For example, the third support plate 23 is moved toward the inside of the apparatus body to receive the third support.

For example, the approaching and separating process of the first body 11 and the second body 12 may be manually driven, or the approaching or separating process of the first body 11 and the second body 12 may be driven by providing a driving device.

Optionally, in the first state of the support assembly, the first support plate 21 is in contact with an adjacent portion of the second support plate 22 to form a complete support surface for the flexible screen 5. In the second state of the support assembly, the third support plate 23 is in contact with adjacent portions of both the first support plate 21 and the second support plate 22 to form a complete support surface for the flexible screen 5.

Alternatively, the third support plate 23 moves synchronously during the driving of the first support plate 21 and the second support plate 22 by the driving assembly. For example, during the process of driving the first support plate 21 and the second support plate 22 away by the driving assembly, the third support plate 23 moves to a position between the first support plate 21 and the second support plate 22, and at least when the position between the first support plate 21 and the second support plate 22 can accommodate the third support plate 23, the third support plate 23 moves to a position between the first support plate 21 and the second support plate 22.

During the process of the driving assembly driving the first support plate 21 to approach the second support plate 22, the third support plate 23 is disengaged from the position between the first support plate 21 and the second support plate 22. The third support plate 23 is detached from the position between the first support plate 21 and the second support plate 22 at least when the third support plate 23 cannot be accommodated at the position between the first support plate 21 and the second support plate 22.

Alternatively, the process of driving the first support plate 21 and the second support plate 22 by the driving assembly is not synchronized with the driving of the third support plate 23.

For example, in the process of switching the supporting component from the first state to the second state, after the driving component drives the first supporting plate 21 and the second supporting plate 22 to be away from each other and the third supporting plate 23 can be accommodated between the first supporting plate 21 and the second supporting plate 22, the driving component drives the third supporting plate 23 to move to a position between the first supporting plate 21 and the second supporting plate 22.

In the process of switching the supporting component from the second state to the first state, after the driving component drives the third supporting plate 23 to separate from the position between the first supporting plate 21 and the second supporting plate 22, the driving component drives the first supporting plate 21 and the second supporting plate 22 to approach each other.

In one embodiment of the present application, the drive assembly includes a first drive assembly, a second drive assembly;

the first driving assembly is connected with the first support plate 21 and the second support plate 22, and the second driving assembly is connected with the third support plate 23. The first driving assembly can drive the first support plate 21 and the second support plate 22 to move. The second driving assembly can drive the third support plate 23 to move.

In the process of switching the supporting component from the first state to the second state, the first driving component drives the first supporting plate 21 and the second supporting plate 22 to move away, and the second driving component drives the third supporting plate 23 to move towards the position between the first supporting plate 21 and the second supporting plate 22.

In the process of switching the supporting component from the second state to the first state, the first driving component drives the first supporting plate 21 and the second supporting plate 22 to approach each other, and the second driving component drives the third supporting plate 23 to separate from the position between the first supporting plate 21 and the second supporting plate 22.

In the embodiment of the application, in the process of switching the support assembly from the first state to the second state, the first support plate 21 and the second support plate 22 are separated from each other to increase the support range formed by the first support plate 21 and the second support plate 22, so as to increase the unfolding size of the flexible screen 5 and realize the unfolding process of the flexible screen 5. The third driving assembly drives the third support plate 23 to move to be located at a position between the first support plate 21 and the second support plate 22, so that the third support plate 23 provides support for the flexible screen 5 at the position between the first support plate 21 and the second support plate 22.

In the process that the supporting component is switched from the second state to the first state, the first supporting plate 21 is close to the second supporting plate 22, so that the supporting range formed by the first supporting plate 21 and the second supporting plate 22 is reduced, the unfolding size of the flexible screen 5 is reduced, and the contraction process of the flexible screen 5 is realized. The third driving member drives the third supporting plate 23 to move so as to be separated from the position between the first supporting plate 21 and the second supporting plate 22, so that the flexible screen 5 is not supported by the third supporting plate 23.

Optionally, the first drive assembly is synchronized with the second drive assembly. For example, the first driving assembly drives the first support plate 21 and the second support plate 22 to move, and the second driving assembly drives the third support plate 23 to move.

Optionally, the first drive assembly is asynchronous with the second drive assembly. For example, when the flexible screen 5 is unfolded, the support assembly is switched from the first state to the second state, and after the first driving assembly drives the first support plate 21 and the second support plate 22 to move away, the second driving assembly drives the third support plate 23 to move between the first support plate 21 and the second support plate 22.

When the flexible screen 5 is contracted, the supporting assembly is switched from the second state to the first state, and after the second driving assembly drives the third supporting plate 23 to be separated from the position between the first supporting plate 21 and the second supporting plate 22, the first driving assembly drives the first supporting plate 21 and the second supporting plate 22 to approach each other.

In one embodiment, as shown in fig. 3 to 7, the first driving assembly includes a first push rod 411 and a second push rod 412, the first push rod 411 is connected to the first support plate 21, the second push rod 412 is connected to the second support plate 22, the first push rod 411 is provided with a first synchronizing tooth 421, the second push rod 412 is provided with a second synchronizing tooth 422, and the first synchronizing tooth 421 is engaged with the second synchronizing tooth 422;

in the process of switching the supporting component from the first state to the second state, the first push rod 411 drives the first supporting plate 21 to move towards the side away from the second supporting plate 22, and the first push rod 411 drives the second synchronizing teeth 422 through the first synchronizing teeth 421 to drive the second push rod 412 to drive the second supporting plate 22 to move towards the side away from the first supporting plate 21;

in the process that the supporting component is switched from the second state to the first state, the first push rod 411 drives the first supporting plate 21 to move towards one side close to the second supporting plate 22, and the first push rod 411 drives the second synchronizing teeth 422 through the first synchronizing teeth 421 to drive the second push rod 412 to drive the second supporting plate 22 to move towards one side close to the first supporting plate 21.

In the embodiment of the present application, the first driving assembly drives the first supporting plate 21 to move through the first push rod 411. The first push rod 411 can drive the second push rod 412 through the first transmission member, so that the second push rod 412 drives the second support plate 22 to move.

When first backup pad 21 and second backup pad 22 are kept away from in the needs, first push rod 411 drives first backup pad 21 and keeps away from second backup pad 22 to first push rod 411 can drive first synchronous tooth 421 and rotate, drives synchronous tooth 422 of second and synchronous tooth 421 through the driven effect of tooth and rotates in step, thereby drives second push rod 412, makes second push rod 412 drive second backup pad 22 and keeps away from first backup pad.

When the first supporting plate 21 and the second supporting plate 22 need to be close to each other, the first push rod 411 drives the first supporting plate 21 and the second supporting plate 22 to be close to each other, and the second push rod 412 drives the second supporting plate 22 and the first supporting plate 21 to be close to each other.

Alternatively, one end of the first push rod 411 is rotatably connected to the apparatus body, and the other end is rotatably connected to the first support plate 21. One end of the second push rod 412 is rotatably connected to the apparatus body, and the other end is rotatably connected to the second support plate 22. The first supporting plate 21 is driven to move by swinging one end of the first push rod 411 connected with the first supporting plate 21, and the second push rod 412 can swing under the driving of the first push rod 411 to drive the second supporting plate 22 to move. For example, the first synchronization tooth 421 is located at a side position of the first push rod 411 biased toward an end connected to the apparatus body. The second synchronizing tooth 422 is located at a side position of the second push rod 412 biased toward the end connected to the apparatus body.

For example, the first push rod 411 drives the first synchronizing gear 421 to rotate during the swinging process, and drives the second synchronizing gear 422 and the first synchronizing gear 421 to rotate synchronously through the action of gear transmission, so as to drive the end of the second push rod 412 connected with the second support plate 22 to swing.

In one embodiment, the second driving assembly comprises a telescopic assembly connected to the third support plate 23;

when the supporting component is switched from the first state to the second state, the telescopic component is expanded to drive the third supporting plate 23 to move to the position between the first supporting plate 21 and the second supporting plate 22;

in the process that the supporting component is switched from the second state to the first state, the telescopic component contracts to drive the third supporting plate 23 to be separated from the position between the first supporting plate 21 and the second supporting plate 22.

In the embodiment of the present application, when the support assembly is in the first state, the third support plate 23 is retracted inside the apparatus body and is located inside the support structure formed by the first support plate 21 and the second support plate 22. The third support plate 23 is driven to contract and expand by the telescopic assembly, so that the third support plate 23 moves to a position between the first support plate 21 and the second support plate 22, and the third support plate 23 is separated from the position between the first support plate 21 and the second support plate 22.

In one embodiment, as shown in fig. 3 to 7, the telescopic assembly includes a first telescopic rod 431 and a second telescopic rod 432, the first telescopic rod 431 includes a first transmission rod 4311 and a first lifting rod 4312, the first transmission rod 4311 is rotatably connected to the first lifting rod 4312, the first transmission rod 4311 is connected to the first push rod 411, the first lifting rod 4312 is rotatably connected to the third support plate 23, the second telescopic rod 432 includes a second transmission rod 4321 and a second lifting rod 4322, the second transmission rod 4321 is rotatably connected to the second lifting rod 4322, the second transmission rod 4321 is connected to the second push rod 412, and the second lifting rod 4322 is rotatably connected to the third support plate 23.

In the embodiment of the present application, the first push rod 411 swings to drive the first transmission rod 4311 to swing, and the first transmission rod 4311 and the first lifting rod 4312 form a foldable telescopic structure. When the first transmission rod 4311 and the first lifting rod 4312 swing to the length direction and are distributed along the same direction, the first telescopic rod 431 has the maximum length. The first transmission rod 4311 can form different angles with the first lifting rod 4312 when swinging to different positions, so that the first telescopic rod 431 has different lengths. The third support plate 23 can be driven to move up and down by the position matching relationship between the first transmission rod 4311 and the first lifting rod 4312. Similarly, the second transmission rod 4321 and the second lifting rod 4322 cooperate to enable the second telescopic rod 432 to have different lengths, so as to drive the third supporting plate 23 to move up and down.

Optionally, a track for moving the third support plate 23 is arranged in the main body of the apparatus, and the first telescopic rod 431 and the second telescopic rod 432 can drive the third support plate 23 to move along the track, so that the third support plate 23 can move in the process of switching the support assembly between the first state and the second state.

Alternatively, as shown in fig. 6 and 7, the first transmission rod 4311 is fixed to an end of the first push rod 411, and the second transmission rod 4321 is fixed to an end of the second push rod 412. So that the first push rod 411 can drive the first transmission rod 4311 to swing, and the second push rod 412 can drive the second transmission rod 4321 to swing. This enables the first driving member and the second driving member to move synchronously, so that when the first support plate 21 and the second support plate 22 are far away from each other to be able to accommodate the third support plate 23, the third support plate 23 can be accurately moved to be located between the first support plate 21 and the second support plate 22.

Alternatively, the swing in this application may be that the first end of the member is not displaced and the second end moves centering on the first end to form the swing. For example, the first end of the first push rod 411 is disposed on the device body, the second end of the first push rod 411 is disposed on the first supporting plate 21, and in the swinging process of the first push rod 411, the first end is rotated as a center, and the second end moves to drive the first supporting plate 21 to move.

Alternatively, the oscillation may be such that the first end of the member is slidable and the second end moves to form the oscillation. For example, the first end of the first push rod 411 is disposed on the device main body, the second end of the first push rod 411 is disposed on the first support plate 21, the first end of the first push rod 411 can slide relative to the device main body, and in the process of swinging the first push rod 411, the first end slides on the device main body, and the second end drives the first support plate 21 to move.

In one embodiment, as shown in fig. 6, the flexible screen device further includes a first motor 44, the first motor 44 is disposed on the device body, and an output end of the first motor 44 is in transmission connection with the first push rod 411.

In the embodiment of the present application, the drive assembly is powered by a first motor 44. The first motor 44 can drive the first push rod 411 to swing. For example, a gear is arranged at one end of the first push rod 411 arranged on the device body, a gear is arranged at the output end of the first motor 44, and the first motor 44 drives the end of the first push rod 411 connected with the first support plate 21 to swing through gear transmission. The first push rod 411 drives the second push rod 412 to swing through the first transmission member.

In one embodiment, as shown in fig. 8 and 9, the second driving member includes a first slide rail 45 and a second slide rail 46, the first slide rail 45 is disposed on the first support plate 21, and the second slide rail 46 is disposed on the second support plate 22;

the first slide rail 45 includes a first slide rail portion 451 and a first bending portion 452, the first bending portion 452 is bent toward a side of the first support plate 21 with respect to the first slide rail portion 451, the second slide rail 46 includes a second slide rail portion 461 and a second bending portion 462, and the second bending portion 462 is bent toward a side of the second support plate 22 with respect to the second slide rail portion 461;

the second driving member further comprises a first sliding block 47 and a second sliding block 48, the first sliding block 47 and the second sliding block 48 are arranged on the third supporting plate 23, the first sliding block 47 is slidably connected with the first sliding rail 45, and the second sliding block 48 is slidably connected with the second sliding rail 46;

when the support assembly is in the first state, the first slider 47 engages the first slide track portion 451 and the second slider 48 engages the second slide track portion 461;

when the supporting assembly is in the second state, the first sliding block 47 is engaged with the first bending portion 452, and the second sliding block 48 is engaged with the second bending portion 462.

In the embodiment of the present application, the moving rail of the third support plate 23 is formed by the first slide rail 45 and the second slide rail 46. In the process of separating the first support plate 21 from the second support plate 22, the first slider 47 moves along the first sliding track portion 451 toward the first bent portion 452, and the second slider 48 moves along the second sliding track portion 461 toward the second bent portion 462. The first bent portion 452 is bent toward the first support plate 21 with respect to the first rail portion 451, and the second bent portion 462 is bent toward the second support plate 22 with respect to the second rail portion 461. When the first slider 47 moves from the first slide rail portion 451 to the first bending portion 452, the third support plate 23 can be driven to approach the first support plate 21. Conversely, when the first slider 47 moves from the first bending portion 452 to the first sliding rail portion 451, the third support plate 23 can be driven to be away from the first support plate 21. The track structure formed by the first bending portion 452 gradually approaches from the side where the first sliding rail portion 451 is located to the side where the first support plate 21 is located.
