Abstract

A flattening structure of a flexible screen ( 100 ), and a display device. The flattening structure includes a flexible screen storage device ( 200 ), a storage blocking member ( 300 ), and an elastic assembly ( 400 ), the flexible screen storage device ( 200 ) includes a housing ( 201 ) and a flexible screen reel ( 202 ) arranged in the housing ( 201 ); one end of the flexible screen ( 100 ) is connected to the flexible screen reel ( 202 ) and capable of being wound on the flexible screen reel ( 202 ), and the other end of the flexible screen ( 100 ) is connected to the storage blocking member ( 300 ) by means of the elastic assembly ( 400 ).

First claim

What is claimed is:

1. A flattening structure of a flexible screen, comprising: a flexible screen storage apparatus, comprising a housing and a flexible screen reel arranged in the housing, wherein the flexible screen reel is connected with one end of the flexible screen and capable of being wound by the flexible screen; a storage blocking member arranged opposite to the flexible screen storage apparatus; and at least one elastic assembly connecting the storage blocking member with another one end of the flexible screen; wherein the another one end of the flexible screen is fixedly connected with a sliding assembly, and the sliding assembly is connected with a first end, away from the storage blocking member, of the at least one elastic assembly; and wherein the sliding assembly is a sliding plate, and the sliding plate completely covers the flexible screen in a direction perpendicular to an unfolding direction of the flexible screen; and the storage blocking member is provided with a sliding groove, and the sliding assembly slides in the sliding groove when the storage block member pulls a second end of the at least one elastic assembly opposite to the first end; and two ends of the sliding groove corresponding to a direction perpendicular to an unfolding direction of the flexible screen are provided with guide rails, and an edge of the sliding assembly is sided along the guide rails.

2. The flattening structure of the flexible screen according to claim 1 , wherein the at least one elastic assembly comprises one elastic assembly, and the one elastic assembly is connected to a middle position of the sliding assembly in a direction perpendicular to an unfolding direction of the flexible screen.

3. The flattening structure of the flexible screen according to claim 1 , wherein the at least one elastic assembly comprises two elastic assemblies, the two elastic assemblies are arranged at two end of a side, facing the storage blocking member, of the sliding assembly, and the two elastic assemblies are symmetrical.

4. The flattening structure of the flexible screen according to claim 1 , wherein the flexible screen storage apparatus is further provided with a flexible screen winding driving apparatus.

5. The flattening structure of the flexible screen according to claim 1 , wherein a locking apparatus is further arranged in the flexible screen storage apparatus, and the locking apparatus is configured to limit an action of the flexible screen.

6. The flattening structure of the flexible screen according to claim 1 , wherein the storage blocking member is a rigid display device.

7. A display apparatus, comprising a flexible screen and a flattening structure of the flexible screen; wherein the flattening structure of the flexible screen, comprising: a flexible screen storage apparatus, comprising a housing and a flexible screen reel arranged in the housing, wherein the flexible screen reel is connected with a first end of the flexible screen and capable of being wound by the flexible screen; a storage blocking member arranged opposite to the flexible screen storage apparatus; and at least one elastic assembly connecting the storage blocking member with another one end of the flexible screen wherein the another one end of the flexible screen is fixedly connected with a sliding assembly, and the sliding assembly is connected with one end, away from the storage blocking member, of the at least one elastic assembly; and wherein the sliding assembly is a sliding plate, and the sliding plate completely covers the flexible screen in a direction perpendicular to an unfolding direction of the flexible screen; and the storage blocking member is provided with a sliding groove, and the sliding assembly slides in the sliding groove when the storage block member pulls a second end of the at least one elastic assembly opposite to the first end; and two ends of the sliding groove corresponding to a direction perpendicular to an unfolding direction of the flexible screen are provided with guide rails, and an edge of the sliding assembly is sided along the guide rails.

8. The display apparatus according to claim 7 , wherein the at least one elastic assembly comprises one elastic assembly, and the one elastic assembly is connected to a middle position of the sliding assembly in a direction perpendicular to an unfolding direction of the flexible screen.

9. The display apparatus according to claim 7 , wherein the at least one elastic assembly comprises two elastic assemblies, the two elastic assemblies are arranged at two end of a side, facing the storage blocking member, of the sliding assembly, and the two elastic assemblies are symmetrical.

10. The display apparatus according to claim 7 , wherein the flexible screen storage apparatus is further provided with a flexible screen winding driving apparatus.

11. The display apparatus according to claim 7 , wherein a locking apparatus is further arranged in the flexible screen storage apparatus, and the locking apparatus is configured to limit an action of the flexible screen.

12. The flattening structure of the flexible screen according to claim 1 , wherein the sliding groove has an opening on a surface of the storage blocking member facing the flexible screen storage apparatus.
