Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
It should be noted that, in case of conflict, different features in the embodiments of the present application may be combined with each other.
In order to better describe the technical solution provided by the embodiment of the present application, please refer to fig. 1, in which fig. 1 shows a schematic side structural view of a support assembly 10 provided by the embodiment of the present application.
In this embodiment, the supporting assembly 10 may include a telescopic supporting portion 10A, a reel 130, a first driving portion 140 and a second driving portion 150.
The extendable support 10A is provided with a first end and a second end opposite to each other in a first direction (arrow direction in the figure), wherein the first end is movable toward the second end along the first direction and is movable away from the second end along the first direction.
The reel 130 is located at a first end of the telescopic support 10A for winding up the flexible display panel. Opposite ends of the flexible display panel are connected to the reel 130 and a second end of the telescopic support 10A, respectively. Since the first end and the second end in this embodiment are opposite ends, the reel 130 may also be located at the second end of the telescopic support 10A.
In this embodiment, the support assembly 10 can be extended and retracted by the mutual cooperation of the telescopic support 10A, the reel 130, the first driving portion 140 and the second driving portion 150. For example, when the support assembly 10 is extended, the first driving portion 140 drives the telescopic support 10A to extend, and the second driving portion 150 drives the roller 130 to rotate (e.g., clockwise), so that the flexible display panel (not shown) at least partially wound on the roller 130 is unwound from the telescopic support 10A. For another example, when the supporting assembly 10 is retracted, the first driving portion 140 drives the retractable supporting portion 10A to retract, and the second driving portion 150 drives the roller 130 to rotate (for example, rotate counterclockwise), so that the flexible display panel at least partially unwound from the retractable supporting portion 10A is wound on the roller 130.
In this embodiment, the retractable supporting portion 10A may be a retractable supporting plate composed of relatively retractable supporting plates, a retractable supporting frame composed of relatively retractable supporting frames, or a retractable supporting frame composed of relatively retractable supporting rods; it should be noted that, for the flexible display panel, it has a layer of flexible steel plate as a support, so the flexible steel plate and the retractable support portion 10A have enough supporting force to support the display panel, thereby ensuring the display panel to be unfolded. It will be appreciated that any support structure that is collapsible and that can be used to support a flexible display panel can be used to make the collapsible support 10A in the embodiments of the present application.
In the above structure, the winding shaft 130 is located at the first end of the telescopic supporting portion 10A, the winding shaft 130 and the second end of the telescopic supporting portion 10A are respectively used for connecting two opposite ends of the flexible display panel, when the supporting assembly 10 extends or contracts, the telescopic supporting portion 10A is driven to extend or contract by the first driving portion 140, and the second driving portion 150 drives the winding shaft 130 to rotate so that the flexible display panel is always in a flat state on the supporting assembly 10, so that the supporting assembly 10 can effectively support the portion of the flexible display panel which is unfolded.
Further, the telescopic supporting portion 10A may include a fixed supporting portion 110 and a movable supporting portion 120, the movable supporting portion 120 may be telescopically connected to the fixed supporting portion 110, wherein a first end may be located on the movable supporting portion 120, and a second end may be located on the fixed supporting portion 110; alternatively, the first end may be located on the fixed support 110 and the second end may be located on the movable support 120. In the embodiment of the present application, it is preferable that the first end is located on the movable support 120, the second end is located on the fixed support 110, and the winding shaft 130 is located on the movable support 120.
The reel 130 and the fixing support 110 are used to connect opposite ends of the flexible display panel. The movable support 120 extends or retracts relative to the fixed support 110, and can drive the reel 130 to move away from or close to the fixed support 110 to change the size of the display area of the flexible display panel. Specifically, in the embodiment of the present application, the reel 130 may be located at an end of the movable support 120 away from the fixed support 110, and thus the display area of the flexible display panel may be increased.
When the movable supporting portion 120 extends and retracts relative to the fixed supporting portion 110, the first driving portion 140 drives the movable supporting portion 120 to move relative to the fixed supporting portion 110, and the second driving portion 150 drives the reel 130 to wind or unwind the flexible display panel, so that the flexible display panel on the fixed supporting portion 110 and the movable supporting portion 120 is always in a flat state. For example, when the first driving part 140 drives the movable supporting part 120 to be far away from the fixed supporting part 110, the second driving part 150 drives the reel 130 to rotate clockwise, so as to unfold the flexible display panel, and the flexible display panel can be flattened on the movable supporting part 120 and the fixed supporting part 110 which are far away from each other; for another example, when the first driving portion 140 drives the movable supporting portion 120 to approach the fixed supporting portion 110, the second driving portion 150 drives the winding shaft 130 to rotate in the counterclockwise direction, so as to wind the flexible display panel, so that the display portion of the flexible display panel can be flattened on the movable supporting portion 120 and the fixed supporting portion 110 which are relatively close to each other.
In a possible implementation manner of the embodiment of the present application, a part of the first driving portion 140 is fixed to the movable supporting portion 120, and another part of the first driving portion 140 is fixed to the fixed supporting portion 110, and the movable supporting portion 120 and the fixed supporting portion 110 can be driven to move relatively by the cooperation of the two parts of the first driving portion 140 respectively located on the movable supporting portion 120 and the fixed supporting portion 110.
The second driving part 150 is fixed on the movable support 120, the second driving part 150 is rotatably connected to the reel 130 to control the rotation direction of the reel 130, and control the winding or unwinding of the flexible display panel through the rotation direction of the reel 130, for example, in fig. 1, when the reel 130 is controlled to rotate in a clockwise direction, the reel 130 can unwind the flexible display panel to increase the display area of the flexible display panel; when the scroll 130 is controlled to rotate in the counterclockwise direction, the scroll 130 may wind the flexible display panel to reduce the display area of the flexible display panel.
In the support assembly 10 provided in the embodiment of the present application, the winding shaft 130 is located on the movable support portion 120, the winding shaft 130 and the fixed support portion 110 are used to connect two opposite ends of the flexible display panel, when the movable support portion 120 stretches relative to the fixed support portion 110, the first driving portion 140 can drive the movable support portion 120 to move relative to the fixed support portion 110, and the second driving portion 150 can drive the winding shaft 130 to wind or unwind the flexible display panel, so that the unwound portion of the flexible display panel can be always in a flat state on the fixed support portion 110 and the movable support portion 120, and the unwound portion of the flexible display panel can be attached to the fixed support portion 110 and the movable support portion 120, so that the unwound portion of the flexible display panel can be effectively supported by the fixed support portion 110 and the movable support portion 120. It is understood that the above process can be controlled by a computer program, so that the flexible display panel on the movable support part 120 and the fixed support part 110 is always in a flattened state during the movement of the movable support part 120 relative to the fixed support part 110.
Further, referring to fig. 1 again, the fixed supporting portion 110 may be provided with an accommodating space for accommodating the movable supporting portion 120. For example, the fixed support part 110 may include a fixed back cover 1101 and a fixed support plate 1102, wherein the fixed back cover 1101 and the fixed support plate 1102 are oppositely disposed, preferably, the fixed back cover 1101 and the fixed support plate 1102 may be disposed in parallel, and the fixed back cover 1101 and the fixed support plate 1102 may be fixed by a support 1103 and form an accommodation space. In the process that the movable supporting portion 120 approaches the fixed supporting portion 110, the portion of the movable supporting portion 120 that is accommodated in the accommodating space is gradually increased, so that the overall occupied space of the structure can be reduced. In the embodiment of the present application, the flexible display panel may be fixed at an end of the fixed support plate 1102 away from the reel 130, so that the support assembly 10 provides as large a support area as possible for the flexible display panel, and ensures a larger display area of the flexible display panel.
