Abstract

A back plate component applicable to a display device is disclosed, wherein at least one reinforcement piece is arranged on the back plate component, the reinforcement piece is left-and-right symmetric with respect to a central axis of a length of the back plate component, and a width of the reinforcement piece in a direction of the central axis of the length is decremented from a middle to both of the sides thereof, wherein the central axis of the length of the back plate component is a central axis perpendicular to a length direction of the back plate component and parallel to a width direction of the back plate component.

First claim

The invention claimed is:

1. A back plate component of a curved display device, wherein at least one reinforcement piece is arranged on the back plate component, the at least one reinforcement piece is left-and-right symmetric with respect to a central axis of a length of the back plate component, and a width of the at least one reinforcement piece in a direction of the central axis of the length of the back plate component is decremented from a middle to both of the sides thereof, wherein the central axis of the length of the back plate component is a central axis perpendicular to a length direction of the back plate component and parallel to a width direction of the back plate component.

2. The back plate component according to claim 1 , wherein the at least one reinforcement piece is a sheet structure, which has a thickness ranging from 0.6 mm to 1.5 mm.

3. The back plate component according to claim 1 , wherein a bending strength of a material of the at least one reinforcement piece is no smaller than that of the back plate component.

4. The back plate component according to claim 1 , wherein the number of the at least one reinforcement piece is larger than three, and the at least one reinforcement piece is arranged to be spaced from each other in the width direction of the back plate component.

5. The back plate component according to claim 1 , wherein the at least one reinforcement piece is secured to the back plate component by spot-welding or riveting or screw connection.

6. The back plate component according to claim 1 , wherein the back plate component is arranged thereon with a first reinforcement piece and a second reinforcement piece, the shapes of which are meniscus, and wherein the first reinforcement piece and the second reinforcement piece are mirrored symmetric with respect to a central axis of the width of the back plate component, which is a central axis perpendicular to the width direction of the back plate component and parallel to the length direction of the back plate component.

7. The back plate component according to claim 1 , wherein a recess is arranged on a center of the at least one reinforcement piece, and wherein a shape of the recess matches an outer contour of the reinforcement piece.

8. A back plate component of a curved display device, wherein a plurality of reinforcement pieces are arranged on the back plate component, a length of each of the reinforcement pieces is no larger than a length of the back plate component, and a width of each of the reinforcement pieces is no larger than a width of the back plate component; and a length direction of the reinforcement pieces is parallel to a length direction or a width direction of the back plate component, and a width direction of the reinforcement pieces is parallel to the width direction or the length direction of the back plate component;
wherein the reinforcement pieces are left-and-right symmetric with respect to a central axis of a length of the back plate component, which is a central axis perpendicular to the length direction of the back plate component and parallel to the width direction of the back plate component; and widths of at least a part of the reinforcement pieces in a direction of the central axis of the length of the back plate component are decremented from a middle to both of the sides thereof.

9. The back plate component according to claim 8 , wherein at least a part of the reinforcement pieces are arranged to be spaced from each other on the back plate component.

10. The back plate component according to claim 8 , wherein a bending strength of materials of at least a part of the reinforcement pieces are no smaller than a bending strength of a material of the back plate component.

11. The back plate component according to claim 8 , wherein each of the reinforcement pieces is a sheet structure, which has a thickness ranging from 0.6 mm to 1.5 mm.

12. The back plate component according to claim 8 , wherein at least a part of the reinforcement pieces are upper-and-lower symmetric with respect to a central axis of a width of the back plate component, which is a central axis perpendicular to the width direction of the back plate component and parallel to the length direction of the back plate component.

13. The back plate component according to claim 12 , wherein lengths of at least a part of the reinforcement pieces in a direction of the central axis of the width are decremented from a middle to both of the sides thereof.

14. A curved display device, comprising a back plate component, wherein at least one reinforcement piece is arranged on the back plate component, the at least one reinforcement piece is left-and-right symmetric with respect to a central axis of a length of the back plate component, and a width of the at least one reinforcement piece in a direction of the central axis of the length of the back plate component is decremented from a middle to both of the sides thereof, wherein the central axis of the length of the back plate component is a central axis perpendicular to a length direction of the back plate component and parallel to a width direction of the back plate component.

15. The curved display device according to claim 14 , wherein the at least one reinforcement piece is a sheet structure, which has a thickness ranging from 0.6 mm to 1.5 mm.

16. The curved display device according to claim 14 , wherein a bending strength of a material of the at least one reinforcement piece is no smaller than that of the back plate component.

17. The curved display device according to claim 14 , wherein the number of the at least one reinforcement piece is larger than three, and the at least one reinforcement piece is arranged to be spaced from each other in the width direction of the back plate component.

18. The curved display device according to claim 14 , wherein the reinforcement piece is arranged on one side of the back plate component proximate to a display screen of the curved display device and/or the other side of the back plate component away from the display screen of the curved display device.
