FIG. 3 is an explosion view of the display device provided by an embodiment of the present disclosure. FIG. 4 is a schematic structural view of a chain provided by an embodiment of the present disclosure.

Referring to FIGS. 1 to 3, an embodiment of the present disclosure provides a display device including a casing 11, a flexible display screen 12, a storage component 13, and a lifting component 13.

The flexible display screen 12 is capable of scrolling inside the casing 11. The storage component 13 is disposed inside the casing 11 and connected to an end of the flexible display screen 12 for rewinding the flexible display screen 12. The lifting component 13 is connected to another end of the flexible display screen 12 for lifting and lowering the flexible display screen 12.

The lifting component includes 14 a chain module 141, one or more connecting rod 142, and a screen supporting plate 143. The chain module 141 is connected to the screen supporting plate 143, the screen supporting plate 143 is connected to the connecting rod 142, and the screen supporting plate 143 is connected to another end of the flexible display screen 12. The chain module 141 is used to drive the screen supporting plate 143 to lift and lower, so that the screen supporting plate drives the flexible display screen 12 and the connecting rod 142 to lift and lower.

The present disclosure provides a display device. The lifting component includes the chain module, one or more connecting rods, and the screen supporting plate. The flexible display screen is connected between the storage component and the screen supporting plate. The chain module is connected to the screen supporting plate, so that the chain module may drive the screen supporting plate to lift and lower, thereby driving the flexible display screen to lift and lower without disposing a plurality of motors, reducing complexity and size of the display device, realizing a smaller curling radius, and increasing an application range of the display device. Furthermore, the screen supporting plate drives the connecting rod to lift and lower to prevent the flexible display screen from shifting during a lifting process of the flexible display screen. The connecting rod supports the screen supporting plate to support the flexible display screen, so as to prevent the flexible display screen from bending.

Specifically, the flexible display screen may be capable of scrolling inside the casing. The flexible display screen may be unfolded and curled. As shown in FIG. 3, when the flexible display screen is unfolded, the flexible display screen is in a flat state. When the flexible display screen is curled, the flexible display screen is curled on a rotating shaft 131.

Specifically, as shown in FIGS. 1 to 3, when the flexible display screen is stored, the flexible display screen may be curled on the rotating shaft. The casing is transparent, so that the flexible display screen may realize display after being curled. When the flexible display screen is unfolded, the flexible display screen may be rotated along the rotating shaft to realize lifting and lowering, so that a lifting height and display pictures of the flexible display screen may be determined according to usage scenarios, thereby realizing the display after being unfolded.

Specifically, in this embodiment of the present disclosure, the flexible display screen may realize lifting and lowering through the chain module, the connecting rod, and the screen supporting plate. The chain module may be stored, the connecting rod may be folded, and an occupied space of the screen supporting plate is smaller. Curling transmission components are reduced, and the display device does not need a plurality of motors for driving, so that an overall size of the display device is smaller. After the flexible display screen is stored, the size of the display device is smaller, so that the occupied space of the display device is smaller, and the display device is convenient to carry. Since the size of each structure of the display device is smaller, a curling radius of the display device may be correspondingly reduced.

Specifically, the connecting rods may be disposed at both sides of the casing, and the connecting rods located at both sides of the casing are symmetrically disposed. The connecting rods are disposed at both left and right sides to support the screen supporting plate, so as to prevent the flexible display screen from falling.

Specifically, each of the connecting rods may include a plurality of parts. For example, each of the connecting rods 142 shown in FIG. 2 and FIG. 3 includes upper and lower parts. When the flexible display screen is lifted and lowered, the screen supporting plate is lifted and lowered to drive the connecting rods to fold and rotate, so that the screen supporting plate may be fixed and supported by the connecting rods, thereby preventing the screen supporting plate from shifting and falling.

Specifically, the screen supporting plate may be fixedly connected to the flexible display screen. The screen supporting plate may be driven to lift and lower by lifting and lowering the screen supporting plate, and the screen supporting plate may support the flexible display screen, thereby preventing the flexible display screen from folding and bending, resulting in a poor display effect of the flexible display screen.

Specifically, a width of the screen supporting plate may be equal to a width of the flexible display screen, so that a contact area between the screen supporting plate and the flexible display screen is larger, the screen supporting plate has a better supporting effect on the flexible display screen, and the screen supporting plate has a better lifting and lowering effect on the flexible display screen.

In some embodiments, as shown in FIGS. 1 to 3, the storage component 13 includes a rotating shaft 131 fixed on the rotating shaft 131 and a coil spring 132 connected to an end of the flexible display screen 12. By fixing the coil spring on the rotating shaft, a relative position of a coil sheet of the coil spring may be adjusted through a rotation of the rotating shaft, so that a change of the spring pre-tightening force may be realized, the flexible display screen fixed on the rotating shaft may be stored or unfolded under control of the spring pre-tightening force of the coil spring and the lifting component, thereby realizing the lifting and lowering of the flexible display screen.

Specifically, since the coil spring is disposed on the rotating shaft, when the flexible display screen needs to be lifted, the flexible display screen is lifted by the lifting component, so that the coil spring is in a stretching state and the pre-tightening force of the spring is increased. When the flexible display screen needs to be stored, the flexible display screen may be stored by the lifting module, and the coil spring is in a contracting state and the pre-tightening force of the spring is reduced, so that the flexible display screen is rewound on the rotating shaft, thereby realizing the lifting and lowering of the flexible display screen.

Specifically, as shown in FIG. 2, a radius R2 of the rotating shaft 131 ranges from 20 mm to 100 mm.

In some embodiments, as shown in FIG. 3, the storage component 13 further includes an adjusting member 133 connected to the coil spring 132 for adjusting an initial pre-tightening force of the coil spring 132. By disposing the adjusting member, the initial pre-tightening force of the coil spring may be adjusted, so that when the initial pre-tightening force of the coil spring is too large, the initial pre-tightening force of the coil spring is reduced to avoid high energy consumption of the lifting component. When the initial pre-tightening force of the coil spring is too small, the initial pre-tightening force of the coil spring is increased, so that the flexible display screen may not be rewound on the rotating shaft to prevent the flexible display screen from being damaged.

Specifically, when the flexible display screen is rewound on the rotating shaft, and the initial pre-tightening force of the coil spring is smaller, the flexible display screen may not be well rewound on the rotating shaft, resulting in a problem that the flexible display screen contacts with other structures and may damage the flexible display screen. Then, the initial pre-tightening force of the coil spring may be adjusted by the adjusting member, so that the coil spring may shrink to tighten the flexible display screen. When the initial pre-tightening force of the coil spring is larger, the flexible display screen is rewound on the rotating shaft. When the flexible display screen needs to be lifted and lowered, the lifting component needs to provide a larger lifting force, resulting in higher energy consumption of the lifting component. Then, the initial pre-tightening force of the coil spring may be adjusted, so that the energy consumption of the lifting component is reduced, thereby reducing the energy consumption of the display device.

Specifically, the adjusting member may be fixed on the bracket with an end of the coil spring.

In some embodiments, as shown in FIGS. 1 to 3, the display device 1 further includes a bracket 15 and a bearing 151. The casing 11 is fixed on the bracket 15, and the connecting rod 142 is connected to the bearing 151 through the bearing 151. By disposing the bracket 15 and the bearing 151, and the bearing 151 is connected to the connecting rod 142, the rotating shaft may be rotated along the bearing 151, and the casing 11 may be fixed on the bracket 15, thereby preventing the flexible display screen from being damaged or the casing is shifted due to vibration when lifting and lowering the flexible display screen.

Specifically, FIG. 3 shows the bearings at a joint of two parts of the connecting rod 142. It is understood that the connecting rod 142 is connected to the casing 11, and a joint of the connecting rod 142 and the casing 11 is further provided with the bearing, and a joint of the connecting rod 142 and the screen supporting plate 143 is further provided with the bearing.

Specifically, when the connecting rod 142 is stored, the connecting rod 142 may be disposed transversely in a direction from one side of the bracket to another side of the bracket, so as to reduce the occupied space.

Specifically, the brackets 15 may be disposed at both sides of the casing. Further, the brackets 15 disposed at both sides of the casing are symmetrically disposed.

Specifically, as shown in FIG. 3, the casing 11 includes a front outer casing 112 and a back outer casing 113. Both the front outer casing 112 and the back outer casing 113 are fixed on the bracket 15, so as to prevent the casing from shifting caused by vibrations of the lifting component, resulting in damaging to the flexible display screen.

Specifically, as shown in FIG. 2, the casing 11 further includes an outer casing reinforcement 111 to prevent the casing 11 from separating, which results in a shifting or exposure of other components, thereby preventing the other components from being damaged.

Specifically, as shown in FIG. 2, a radius R1 of the casing 11 ranges from 50 mm to 200 mm.

In some embodiments, as shown in FIGS. 1 to 4, the chain module 141 includes a driving motor (not shown in the figures) and a chain 21. The chain 21 is connected between the driving motor and the screen supporting plate 143. By using the driving motor to drive the chain, the chain may be driven upward according to a certain track to drive the screen supporting plate to move, the screen supporting plate may drive the flexible display screen and the connecting rod to move, thereby realizing the lifting and lowering of the flexible display screen without disposing a plurality of driving mechanisms and transmission mechanisms to drive, reducing the complexity and size of the display device, realizing a smaller curling radius, increasing the application range of the display device. Furthermore, the connecting rod may prevent the flexible display screen from shifting during the lifting process of the flexible display screen, and the connecting rod may support the screen supporting plate to support the flexible display screen, so as to prevent the flexible display screen from bending.

Specifically, the driving motor includes a deceleration motor.

Specifically, when the flexible display screen needs to be lifted and lowered, the chain may be driven to move by the driving motor. When the chain is installed, the chain may be limited to move in the certain track, such as moving in a vertical direction outside the casing, so as to drive the screen supporting plate to move, and the screen supporting plate drives the flexible display screen to move, thereby preventing the flexible display screen from wrinkling or bending, caused by an uncertain moving direction of the chain.

Specifically, the embodiment of the present disclosure merely needs one driving motor to drive the flexible display screen to move the transmission of the chain, the connecting rod, and the screen supporting plate, without disposing the plurality of driving mechanisms and transmission mechanisms, thereby reducing the complexity and size of the display device, realizing smaller curling radius, and increasing the application range of the display device. Furthermore, the screen supporting plate may support the flexible display screen to prevent the flexible display screen from bending.

In some embodiments, as shown in FIG. 4, the chain 21 includes an outer chain plate 211, an inner chain plate 212, a pin shaft 213, and a roller 214. The outer chain plate 211 is fixed with the inner chain plate 212 through the pin shaft 213 at a side of the inner chain plate 212, and the outer chain plate 211 is fixed with the inner chain plate 212 through the roller 214 at another side of the inner chain plate 212. Opposite sides of the outer chain plate 211 and the inner chain plate 212 are both provided with a bending part 215, and a bending direction of the bending part 215 of the outer chain plate 211 is opposite to a bending direction of the bending part 215 of the inner chain plate 212. The chain includes the outer chain plate, the inner chain plate, the pin shaft, and the roller, the outer chain plate and the inner chain plate on both sides are respectively fixed through the pin shaft and the roller, and both the outer chain plate and the inner chain plate are provided with the bending part, so that when the chain is lifted, the bending parts of the outer chain plate and the inner chain plate contact each other to ensure that the chain is straight, thereby driving the flexible display screen to lift and lower. When the chain needs to be rolled up, a side of the chain without the bending part of the inner chain plate may be folded and rolled into the casing to prevent the chain from occupying too much space.

Specifically, as shown in FIG. 4, one side of the inner chain plate 212 is provided with the bending part 215, and another side of the inner chain plate 212 is not provided with the bending part. When the connecting rod needs to be lifted by the chain, the bending part 215 of the inner chain plate 212 may be contacted with the bending part 215 of the outer chain plate 211, so that the inner chain plate 212 and the outer chain plate 211 may be blocked, and the chain may be straightened to lift the flexible display screen. When the chain needs to be rolled up, the chain may be folded from the side of the inner chain plate 212 where the bending part is not provided, so that the chain may be rolled up to prevent the chain module from occupying too much space.

Regarding the high vibration during the chain transmission process, there may be problems such as chain displacement, in some embodiments, as shown in FIG. 2 and FIG. 3, the display device 1 further includes a chain back cover 16 disposed in a lifting area of the chain. The chain back cover 16 is telescoped movable. By disposing the chain back cover, the chain is limited in the chain back cover during the transmission process, so as to avoid damage to the flexible display screen caused by displacement during the transmission process of the chain, and prevent displacement or damage to other components caused by vibration during during the transmission process of the chain.

Specifically, the chain back cover 16 may be telescoped movable, and the chain back cover includes a plurality of foldable parts, so that the chain back cover may be stored and unfolded through the lifting and lowering of the plurality of foldable parts in the lifting process of the chain, so that the chain may be limited and protected when the chain is lifted and lowered, and the chain back cover may further be folded and stored when the chain is stored, thereby prevent the chain back cover from occupying excessive space.

Specifically, when the chain back cover is in a unfolding state, cross-sectional areas of the plurality of foldable parts of the chain back cover sequentially decrease along a direction from the screen supporting plate to the chain module, so that other parts of the chain back cover may be stored in a part at a lowest side, and the storage and unfolding processes of the plurality of foldable parts of the chain back cover are convenient without problems such as jamming.

Specifically, a material of the chain back cover includes metal.

Regarding the problem of the flexible display screen being curled inside the casing and potentially causing damage due to contact with other components. In some embodiments, as shown in FIG. 3, the display device 1 further includes a circular arc track 17 disposed inside the casing 11. When the flexible display screen 12 is lifted and lowered, the flexible display screen 12 moves along the circular arc track 17. By disposing the circular arc track inside the casing, the flexible display screen moves along the circular arc track when being lifted, so as to prevent the friction damage of the flexible display screen on the casing and the friction damage of the flexible display screen with other components.

Specifically, when the circular arc track is disposed inside the casing, the flexible display screen can keep a certain distance from the casing.
