[0024] As Figures 1-7 shown: A canopy structure of an outdoor sunshade umbrella includes an upper umbrella disk 1, a lower umbrella disk 2, umbrella ribs 3 and a support rod 4. One end of the umbrella rib 3 is rotatably arranged on the upper umbrella disk 1, one end of the support rod 4 is rotatably arranged on the lower umbrella disk 2, and the other end of the support rod 4 is rotatably connected to the middle end of the umbrella rib 3. By driving the lower umbrella disk 2 away from or close to the upper umbrella disk 3 by an external force, the canopy can be controlled to be retracted or opened. The cross-section of the umbrella rib 3 is an elliptical structure, and when supporting the canopy, the short side of the umbrella rib is arranged downward, which can improve the support strength of the canopy. And it includes a long umbrella rib 31, a short umbrella rib 32 and an elastic connection device 33. Both the long umbrella rib 31 and the short umbrella rib 32 are hollow structures, and one end of the short umbrella rib 32 has a constricted part 34 for facilitating insertion into the long umbrella rib 31. The short umbrella rib 32 is always connected to the long umbrella rib 31 through the elastic connection device 33. The elastic connection device 33 includes a support torsion spring 331 and an elastic cord 332.
