It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

Fig. 1-12 are diagrams of an electronic device according to an embodiment of the present application, where the electronic device includes: a flexible screen 100, a telescopic bracket 200 and a driving device 300;

the flexible screen 100 is laid on the surface of the flexible support 200, the first end 101 of the flexible screen 100 is connected with the flexible support 200, and the second end 102 of the flexible screen 100 is connected with the driving device 300;

the driving device 300 is used for driving the flexible screen 100 to move so as to drive the telescopic bracket 200 to move between an extended state and a retracted state;

with the telescopic bracket 200 in the extended state, the first side 201 includes a first region 203 and a second region 204, and the flexible screen 100 covers the first region 203 and the second region 204;

with the telescoping support 200 in the retracted state, the flexible screen 100 covers the first region 203 and the second side 202.

The extended state may refer to a state in which the telescopic bracket 200 is fully extended, and correspondingly, the retracted state may refer to a state in which the telescopic bracket 200 is fully retracted. Specifically, referring to fig. 3, fig. 3 is a schematic structural diagram of the electronic device in the extended state of the telescopic bracket 200, where the display area of the first side 201 is the largest, and the first side 201 includes a first area 203 and a second area 204. During the gradual retraction of the telescopic support 200 from the extended position, the display area of the second area 204 gradually decreases until the telescopic support 200 is fully retracted to the retracted position as illustrated in fig. 2, at which time the first side 201 comprises only the first area 203.

It will be appreciated that the telescopic bracket 200 may be moved to any telescopic position between the telescopic state and the retracted state, in addition to the extended state and the retracted state, so that the adjustment of the display area of the first side 201 may be achieved by controlling the telescopic movement of the telescopic bracket 200.

Further, referring to fig. 2, in the case where the telescopic stand 200 is in the retracted state, since the flexible screen 100 covers both the first side 201 and the second side 202 of the telescopic stand 200, the electronic apparatus may also form a double-sided screen in this state. Thereby further improving the adjustability of the form of the flexible screen 100 and alleviating the problem that the existing display screen is not adjustable in form.

Referring to fig. 3, in the process of adjusting the shape of the flexible screen 100, the driving device 300 may drive the second end 102 of the flexible screen 100 to move in the second side 202 along the side toward the first end 101 of the flexible screen 100, and in this process, the first end 101 of the flexible screen 100 drives the telescopic bracket 200 to retract, that is, drives the first bracket 205 of the telescopic bracket 200 to move toward the second bracket 206, and the display area of the first side 201 gradually decreases, and the display area of the second side 202 gradually increases until moving to the retracted state as described in fig. 2.

In this embodiment, the flexible screen 100 is laid on the surface of the telescopic support 200, so that the flexible screen 100 and the telescopic support 200 synchronously move under the driving of the driving device 300, so as to change the shape of the flexible screen 100, wherein the flexible screen 100 can form a telescopic screen in the telescopic process of the telescopic support 200, and the flexible screen 100 can form a double-sided screen when the telescopic support 200 is in a retracted state, thereby effectively improving the shape adjustability of the flexible screen 100 and alleviating the problem that the existing display screen has an unadjustable shape.

Optionally, the telescopic bracket 200 includes a telescopic end and a fixed end that are disposed opposite to each other;

the first end 101 is connected with the telescopic end, the second end 102 sequentially bypasses the first side 201 and the fixed end and extends to the second side 202, and the driving device 300 is used for driving the second end 102 to move in the second side 202;

the second end 102 is adjacent to the fixed end with the telescoping support 200 in the extended state and the second end 102 is adjacent to the telescoping end with the telescoping support 200 in the retracted state.

The telescopic end may refer to an end that reciprocates during the telescopic operation of the telescopic bracket 200, and the fixed end may refer to an end that maintains a constant position during the telescopic operation of the telescopic bracket 200. It will be appreciated that the distance between the telescopic end and the fixed end is continuously changed during the telescopic movement of the telescopic bracket 200, the distance between the telescopic end and the fixed end is increased during the extension of the telescopic bracket 200, and the distance between the telescopic end and the fixed end is gradually decreased during the retraction of the telescopic bracket 200.

In this embodiment, by connecting the first end 101 of the flexible screen 100 to the telescopic end and making the second end 102 of the flexible screen 100 bypass the first side 201 and the fixed end in sequence and extend to the second side 202, as shown in fig. 3, when the driving device 300 drives the second end 102 of the flexible screen 100 to move towards the telescopic end, the first end 101 of the flexible screen 100 may pull the telescopic end to retract. Accordingly, as shown in fig. 2, when the telescopic bracket 200 drives the second end 102 of the flexible screen 100 to move toward the fixed end, the second end 102 of the flexible screen 100 may push the telescopic end to extend. Thus, the telescopic movement of the telescopic bracket 200 can be controlled.

Optionally, the telescopic bracket 200 includes a first bracket 205 and a second bracket 206, where the first bracket 205 and the second bracket 206 are stacked, and the first bracket 205 is movable between an overlapping position and a dislocated position relative to the second bracket 206 to implement extension and retraction of the telescopic bracket 200;

with the telescopic bracket 200 in the extended state, the first bracket 205 moves to the dislocated arrangement relative to the second bracket 206;

with the telescoping support 200 in the retracted state, the first support 205 is moved to the overlapping position relative to the second support 206.

Wherein the fixed end may be located on the second bracket 206, and the telescopic end may be located on the first bracket 205.

Specifically, the first bracket 205 may be slidably connected to the second bracket 206, and the overlapping area between the first bracket 205 and the second bracket 206 is continuously changed during the sliding of the first bracket 205 relative to the second bracket 206. Referring to fig. 2, the first bracket 205 is located at an overlapping position, where the first bracket 205 is overlapped with the second bracket 206, and an overlapping area between the first bracket 205 and the second bracket 206 is the largest. When the first support 205 extends relative to the second support 206, the overlapping area between the first support 205 and the second support 206 gradually decreases until moving to the dislocated position shown in fig. 3, at which time the overlapping area between the first support 205 and the second support 206 is minimal.

Optionally, the driving device 300 includes a driving assembly and a conveyor belt 301, and a length direction of the conveyor belt 301 is the same as a telescoping direction of the telescoping support 200;

the driving assembly is connected with the conveyor belt 301 to drive the conveyor belt 301 to rotate forward or backward;

the second end 102 is connected to the conveyor belt 301, and the second end 102 is driven by the conveyor belt 301 to reciprocate in the second side 202 during the forward rotation or the reverse rotation of the conveyor belt 301.

Referring to fig. 2 to 3, the conveyor belt 301 may be mounted on the second bracket 206, for example, the conveyor belt 301 may be mounted on a side portion of the second bracket 206, an upper surface of the conveyor belt may be flush with the first side 201, and a lower surface of the conveyor belt may be flush with the second side 202.

The second end 102 of the flexible screen 100 may be adhered to the conveyor belt 301, and the flexible screen 100 may be slid with respect to the second support 206, i.e., the position between the flexible screen 100 and the second support 206 may be relatively changed. Thus, during the forward and reverse rotation of the conveyor belt 301, the conveyor belt 301 may drive the second end 102 of the flexible screen 100 to reciprocate within the second side 202. Specifically, referring to fig. 2, when the conveyor belt 301 rotates clockwise, the second end 102 of the flexible screen 100 will move leftwards, i.e. to the fixed end, along with the conveyor belt 301 because the conveyor belt is fixedly connected with the second end 102 of the flexible screen 100, and at this time, the flexible screen 100 slides integrally to the second side 202 of the telescopic bracket 200, and the first end 101 of the flexible screen 100 pushes the first bracket 205 to extend, so that the area of the flexible screen 100 located in the first side 201 is increased, i.e. the display area of the first side 201 is increased. Accordingly, when the belt rotates counterclockwise, the first end 101 of the flexible screen 100 pulls the first bracket 205 to retract, and at the same time, the flexible screen 100 slides toward the second side 202 as a whole, the display area of the first area decreases, and the display area of the second side 202 increases.

Optionally, the driving device 300 includes a driving member 302, a driving shaft 303, a driven shaft 304, a driving wheel 305, and a driven wheel 306, where the driving member 302 is connected to the driving shaft 303 to drive the driving shaft 303 to rotate;

the driving wheel 305 is sleeved on the driving wheel 303, the driven wheel 306 is sleeved on the driven wheel 304, and the conveying belt 301 is arranged on the driving wheel 305 and the driving wheel;

during the rotation of the driving shaft 303, the driving shaft 303 drives the conveyor belt 301 to rotate in a forward or reverse direction, and the driven wheel 306 follows the conveyor belt 301 to rotate.

Referring to fig. 2 to 3, the driving shaft 303 and the driven shaft 304 may be disposed at both ends of the second bracket 206, respectively, and the driving shaft 303 and the driven shaft 304 may be disposed perpendicular to the telescopic direction of the telescopic bracket 200, respectively. Thus, when the driving shaft 303 rotates, any point on the conveyor belt 301 reciprocates along the telescopic direction of the telescopic bracket 200, and since the second end 102 of the flexible screen 100 is connected to a certain position on the conveyor belt 301, the conveyor belt 301 will drive the second end 102 of the flexible screen 100 to reciprocate along the telescopic direction of the telescopic bracket 200, so as to push the first bracket 205 to perform telescopic motion.

Referring to fig. 1, in one embodiment of the present application, the number of driving shafts 303 is 2, two ends of the 2 driving shafts 303 respectively extend out of the second bracket 206 from two sides of the second bracket 206, and two driving shafts 303 are respectively provided with one driving wheel 305. The number of driven shafts 304 may be 1, and two ends of the driven shafts 304 extend from two sides of the second support 206, where, of course, the number of driven shafts 304 may be 2, two ends of 2 driven shafts 304 extend from two sides of the second support 206 outside the second support 206, and driven shafts 304 extending from two sides of the second support 206 are respectively sleeved with one driven wheel 306. Correspondingly, the number of the driving belts is 2, and 2 driving belts 301 are respectively arranged on the driving wheel 305 and the driven wheel 306 at two sides of the second bracket 206. In a specific implementation, two driving members 302 may be used to drive two driving shafts 303 respectively, and of course, a motor including two output shafts as shown in fig. 1 may also be used, where the motor and the two driving shafts 303 are arranged on the same line, and the two output shafts of the motor are connected with the two driving shafts 303 respectively through a speed reducer, so as to drive the two driving shafts 303 to rotate synchronously. It can be appreciated that the two sides of the flexible screen 100 are respectively connected with the two conveyor belts 301, so that the uniformity of the stress of the flexible screen 100 can be improved, and the problem of jamming during the movement of the flexible screen 100 can be avoided.

The driving wheel 305 and the driven wheel 306 may be pulleys, respectively, and the belt 301 may be driven to rotate in a forward or reverse direction by the pulleys. In addition, referring to fig. 2, the driving wheel 305 and the driven wheel 306 may also respectively use gears, and correspondingly, inner teeth are disposed on an inner side wall of the driving belt, and the driving wheel 305 and the driven wheel 306 are respectively engaged with the inner teeth of the driving belt 301 to drive the driving belt 301 to rotate in a forward or reverse direction, so that the movement accuracy of the driving belt 301 can be improved by adopting a gear connection manner.

In another embodiment of the present application, the driving device 300 may also include a driving assembly and a transmission chain, where the driving assembly is connected to the transmission chain to drive the transmission chain to rotate in a forward direction or a reverse direction; the second end 102 is connected to the driving chain, and the second end 102 is driven by the driving chain to reciprocate in the second side 202 during the forward rotation or the reverse rotation of the driving chain.

In this embodiment, the position of the telescopic bracket 200 is locked by providing the locking assembly, so that abnormal telescopic movement of the telescopic bracket 200 when in the extended state and the retracted state can be prevented.

Alternatively, the surface of the first bracket 205 is formed with a sliding portion 209, the second bracket 206 is formed with a slide 210 arranged along the telescopic direction of the telescopic bracket 200, and the first bracket 205 is slidably connected with the slide 210 through the sliding portion 209;

the locking assembly is disposed between the sliding portion 209 and the slideway 210, one end of the locking assembly is connected with the sliding portion 209, and the other end is abutted against the inner wall of the slideway 210;

a first limit groove 211 and a second limit groove 212 are formed at two ends of the inner wall of the slideway 210, and at least part of the locking component is embedded into the first limit groove 211 to lock the relative positions of the first bracket 205 and the second bracket 206 when the telescopic bracket 200 is in the extended state;

with the telescoping support 200 in the retracted state, at least a portion of the locking assembly is embedded within the second limit groove 212 to lock the relative position of the first support 205 and the second support 206.

Referring to fig. 1 and referring to fig. 10, the sliding portion 209 may include a plurality of bar-shaped sliding rails, and the length direction of the bar-shaped sliding rails is consistent with the telescopic direction of the telescopic bracket 200, and the plurality of bar-shaped sliding rails are spaced apart from the surface of the first bracket 205. Correspondingly, the second support 206 is provided with a plurality of sliding ways 210 corresponding to the plurality of bar-shaped sliding ways one by one, and each bar-shaped sliding way is respectively connected with the corresponding sliding way 210 in a sliding way, so that stability of the telescopic support 200 in the telescopic process can be improved.

The locking assembly may be disposed in one of the plurality of bar-shaped sliding rails, for example, the plurality of bar-shaped sliding rails includes a first bar-shaped sliding rail, the plurality of sliding rails 210 includes a first sliding rail 210, the first bar-shaped sliding rail corresponds to the first sliding rail 210, and the first bar-shaped sliding rail is slidably connected to the first sliding rail 210. In this case, the locking assembly may be disposed between the first bar-shaped slide rail and the first slide rail 210, such that when the telescopic bracket 200 moves to the extended state and the retracted state, the locking assembly is controlled to lock the relative position between the first bar-shaped slide rail and the first slide rail 210, thereby achieving the position locking of the telescopic bracket 200. In addition, one locking assembly may be disposed in each of the bar-shaped slide rails.

When the telescopic bracket 200 is in the extended state, the belt 301 can be controlled to stop rotating, and meanwhile, the locking piece 208 extends into the first limiting groove 211 under the action of the elastic force of the elastic piece 207, so that the relative position of the first bracket 205 and the second bracket 206 is locked. Accordingly, when the telescopic bracket 200 is in the retracted state, the belt 301 can be controlled to stop rotating, and at this time, the locking member 208 stretches into the second limiting groove 212 under the action of the elastic force of the elastic member 207, so as to lock the relative positions of the first bracket 205 and the second bracket 206.

Accordingly, when it is required to control the telescopic bracket 200 to move from the retracted position to other positions, the movement of the conveyor belt 301 may be controlled, and at this time, the conveyor belt 301 pushes the first bracket 205 through the flexible screen 100, since the second limiting groove 212 is an arc-shaped groove, one end of the locking member 208 contacting the sliding rail 210 is formed with an arc-shaped surface protruding toward the sliding rail 210, so that the locking member 208 slides along the groove wall of the arc-shaped groove, and at the same time, the locking member 208 compresses the elastic member 207, thereby disengaging from the second limiting groove 212, so as to release the locking of the telescopic bracket 200 by the locking assembly.
