Abstract

An exemplary supporting structure is provided for supporting a flat panel display. The supporting structure includes a brace and a base. The brace includes a chassis and a number of arms movably connected to the chassis. The chassis includes a supporting portion surface, an opposite grasp portion surface, and a side surface connecting the supporting portion surface and the grasp portion surface. The supporting portion surface is positioned against the back surface of the flat panel display. The chassis defines a number of side openings on the side surface from the grasp portion surface and along a direction parallel to the axis of the chassis. The base includes a casing sleeved on the chassis therein. The casing defines a number of cutouts corresponding to the side openings and cooperates with the side openings to define a number of sliding grooves for the arms sliding therein respectively.

Claims

1. A supporting structure for a flat panel display, the supporting structure comprising:

a brace locking the flat panel display, the brace comprising;

a chassis comprising a supporting portion surface, an opposite grasp portion surface, and a side surface connecting the supporting portion surface and the grasp portion surface, the supporting portion surface being positioned against a back surface of the flat panel display;

the chassis defining a plurality of side openings in the side surface; and

a plurality of arms movably connected to the chassis and configured for fastening the flat panel display; and

a base comprising a casing sleeved on the chassis therein and configured for latching with the arms, the casing defining a plurality of cutouts corresponding to the side openings and corporating with the side openings to define a plurality of sliding grooves for the arms sliding therein respectively to adjust an angle between the arms and the chassis.

2. The supporting structure as claimed in claim 1, wherein the chassis defines a receiving cavity therein, all of the side openings communicated with the receiving cavity.

3. The supporting structure as claimed in claim 1, wherein the number of the side openings is four.

4. The supporting structure as claimed in claim 1, wherein a plurality of ledges forms on the inner side surface of the chassis corresponding to the side openings.

5. The supporting structure as claimed in claim 4, wherein each ledge comprises a ledge surface facing the grasp portion surface and is substantially parallel to the grasp portion surface, the distance between the ledge surface and the grasp portion surface being larger than the length of the side openings.

6. The supporting structure as claimed in claim 2, wherein each arm is adjustable in length and comprises a supporting portion, a grasp portion, and a resilient portion, one end of the supporting portion rotatably received in the receiving cavity, the other end of the supporting portion adjustably connected with the resilient portion, one end of the grasp portion fixed to the resilient portion, the other end of the grasp portion comprising a hook engaging with a corner of the flat panel display.

7. The supporting structure as claimed in claim 6, wherein the supporting portion comprises a spherical portion and an extending portion connected to the spherical portion, the diameter of the spherical portion being smaller than the diameter of the receiving cavity and larger than the diameter of the side opening on the side surface.

8. The supporting structure as claimed in claim 7, wherein the extending portion comprises a cylindrical portion and a rack portion on one end opposite to the spherical portion, the rack portion comprising a plurality of teeth on the cylindrical surface of the extending portion.

9. The supporting structure as claimed in claim 7, wherein the resilient portion comprises:

a joint member connecting the extending portion of the supporting portion and the grasp portion;

a latching member received in the joint member and latching the extending portion;

an operating lever rotatably connected to the joint member and configured for adjusting the tighteness of the extending portion; and

a connecting member connecting the latching member and the operating lever, wherein when the operating lever is rotated, the connecting member drives the latching member to grasp or release the extending portion.

10. The supporting structure as claimed in claim 9, wherein the latching member comprises:

a grasp member sleeved on the extending portion configured for grasping the extending portion; and

a fastening ring movably sleeved on the grasp member and capable of driving the grasp member to grasp or release the extending portion.

11. The supporting structure as claimed in claim 9, wherein the joint member comprises a receiving portion and a fulcrum portion formed on the receiving portion, the latching member received in the receiving portion.

12. The supporting structure as claimed in claim 11, wherein the fulcrum portion defines a through hole therein and comprises a top surface defining an opening thereon, the opening communicating with the through hole.

13. The supporting structure as claimed in claim 11, wherein the joint member further comprises a latching unit, the latching unit comprising a latching end and a driven end opposite to the latching end, the latching unit rotatably connected to the fulcrum portion.

14. The supporting structure as claimed in claim 13, wherein the joint member further comprises a resilient unit driving the driven end of the latching unit, the resilient unit comprising a plurality of resilient ends, the resilient unit rotatably connected to the fulcrum portion with one of the resilient ends resisting the driven end of the latching unit and the other resilient end resisting the fulcrum portion.

15. The supporting structure as claimed in claim 10, wherein the grasp member comprises a sleeve portion and a gripping portion, the gripping portion comprising a plurality of independent resilient claws, a limiting block integerally formed on a distal end of each claw for preventing the fastening ring from disengaging off the gripping portion.

16. The supporting structure as claimed in claim 9, wherein the connecting member comprises two link lever portions, and each link lever portion comprises a first link lever, a second link lever and a third link lever, the first link lever, the second link lever, and the third link lever rotatably connected to each other in sequence.

17. The supporting structure as claimed in claim 11, wherein the resilient portion further comprises a spring received in the receiving portion and positioned between the latching member and the fulcrum portion.

18. The supporting structure as claimed in claim 1, wherein the casing defines at least one first screw hole thereon and the chassis defines at least one second screw hole thereon corresponding to the first screw hole, the chassis fixed in the casing by at least one bolt threadedly engaging in the first and second screw holes.

19. A flat panel display assembly comprising:

a flat panel display comprising a back surface; and

a supporting structure supporting the flat panel display, the supporting structure comprising;

a brace locking the flat panel display, the brace comprising;

a chassis comprising a supporting portion surface, an opposite grasp portion surface, and a side surface connecting the supporting portion surface and the grasp portion surface, the supporting portion surface resisting to the back surface of the flat panel display;
