Abstract

A supporting assembly, a displaying module and a displaying device are provided by the present disclosure. The supporting assembly includes: a plurality of supporting strips that are disposed separately, wherein one of two neighboring supporting strips includes a first side wall, the other of the two neighboring supporting strips includes a second side wall, the first side wall and the second side wall face and are separate from each other, and a gap between the first side wall and the second side wall includes an unlocking region and a locking region; and one side of each of the plurality of supporting strips is configured to be connected to a flexible display panel; and a locking block movably disposed between the first side wall and the second side wall. The supporting assembly has a low requirement on the machining precision.

First claim

1 . A supporting assembly, wherein the supporting assembly comprises:
a plurality of supporting strips that are disposed separately, wherein one of two neighboring supporting strips comprises a first side wall, the other of the two neighboring supporting strips comprises a second side wall, the first side wall and the second side wall face and are separate from each other, and a gap between the first side wall and the second side wall comprises an unlocking region and a locking region; and one side of each of the plurality of supporting strips is configured to be connected to a flexible display panel; and a locking block movably disposed between the first side wall and the second side wall, wherein when the locking block is located within the unlocking region, the flexible display panel located between the two neighboring supporting strips is bendable, and when the locking block moves to the locking region, the locking block contacts the first side wall and the second side wall at a same time.

2 . The supporting assembly according to claim 1 , wherein when the locking block is located within the locking region, the locking block is interference-fitted to the first side wall and the second side wall.

3 . The supporting assembly according to claim 1 , wherein a minimum distance between the first side wall and the second side wall within the locking region is less than a minimum distance between the first side wall and the second side wall within the unlocking region.

4 . The supporting assembly according to claim 3 , wherein the unlocking region and the locking region are arranged in an extending direction of the supporting strips.

5 . The supporting assembly according to claim 4 , wherein the first side wall comprises a first guiding surface located within the unlocking region, and in a direction from the unlocking region pointing to the locking region, the first guiding surface is gradually close to the second side wall; and/or the second side wall comprises a second guiding surface located within the unlocking region, and in the direction from the unlocking region pointing to the locking region, the second guiding surface is gradually close to the first side wall; and
when the locking block moves between the unlocking region and the locking region, the first guiding surface and/or the second guiding surface are configured to guide the locking block.

6 . The supporting assembly according to claim 5 , wherein the locking block comprises a circular-arc surface, and when the locking block is located within the unlocking region, the circular-arc surface contacts the first guiding surface and/or the second guiding surface.

7 . The supporting assembly according to claim 1 , wherein the supporting strips is provided with a first limiting portion, the locking block is provided with a second limiting portion, and when the locking block is located within the locking region, the first limiting portion and the second limiting portion cooperate to stop the locking block from disengaging from the locking region.

8 . The supporting assembly according to claim 7 , wherein the first limiting portion is a slot, and the second limiting portion is a protrusion; or the first limiting portion is a protrusion, and the second limiting portion is a slot; and
when the locking block is located within the locking region, the protrusion is stuck in the slot.

9 . The supporting assembly according to claim 7 , wherein the supporting assembly further comprises an elastic piece, the elastic piece is connected to the locking block, and when the locking block is located within the locking region, the elastic piece has elastic deformation, and generates an elastic force from the locking region pointing to the unlocking region.

10 . The supporting assembly according to claim 9 , wherein the elastic piece, the locking block and the supporting strips are manufactured through an integral molding process.

11 . The supporting assembly according to claim 1 , wherein when the locking block is located within the unlocking region, the locking block does not contact the first side wall and/or the second side wall.

12 . The supporting assembly according to claim 1 , wherein a plurality of locking blocks are disposed between the first side wall and the second side wall, and the plurality of locking blocks are arranged separately in an extending direction of the supporting strips.

13 . A displaying module, wherein the displaying module comprises a flexible display panel and the supporting assembly according to claim 1 , and the supporting assembly is connected to one side of the flexible display panel.

14 . A displaying device, wherein the displaying device comprises an accommodation component and the displaying module according to claim 13 , the displaying module comprises a first end and a second end facing each other in a direction perpendicular to the supporting strips, and the first end is connected to the accommodation component; and
the accommodation component comprises a guiding piece, and when the second end of the displaying module moves in a direction away from the accommodation component, the locking blocks passing through the guiding piece move from the unlocking regions to the locking regions under driving of the guiding piece.

15 . The displaying device according to claim 14 , wherein when the second end of the displaying module moves toward the accommodation component, the locking blocks passing through the guiding piece move from the locking regions to the unlocking regions under the driving of the guiding piece.

16 . The displaying device according to claim 14 , wherein a guiding track is disposed in the guiding piece, the locking blocks passing through the guiding piece are acting locking blocks, and at least part of each of the acting locking blocks is located inside the guiding track, and is movable along the guiding track; and
the guiding track extends in the direction perpendicular to the supporting strips, the guiding track comprises a first region close to the accommodation component and a second region away from the accommodation component, and in the direction perpendicular to the supporting strips, the first region faces the unlocking regions, and the second region faces the locking regions.

17 . The displaying device according to claim 14 , wherein the displaying module comprises a third end and a fourth end facing each other in a direction parallel to the supporting strips, the displaying module further comprises a plurality of sliding shafts, the plurality of sliding shafts are arranged separately in the direction perpendicular to the supporting strips, the sliding shafts are located at the third end and/or the fourth end of the displaying module, the accommodation component comprises a spiral track, and at least part of each of the sliding shafts is embedded inside the spiral track, and is movable along the spiral track.

18 . The displaying device according to claim 17 , wherein the accommodation component further comprises a driving arm, one end of the driving arm cooperates with at least one of the sliding shafts, and the other end of the driving arm is rotatably connected to a center of the spiral track.
