Abstract
An umbrella structure is provided, including a main frame, a cap body, a plurality of ribs, and a driving component. The main frame is a tube structure. The cap body is an elliptical layered structure, and a center of one surface of the cap body connects to one tip of the main frame. The plurality of ribs are disposed on the surface of the cap body. Each tip of the plurality of ribs connects to the tip of the main frame and each of the other tips of the plurality of ribs connects to a periphery of the cap body. One tip of the driving component movably sheathes the main frame and the other tip of the driving component connects to the plurality of ribs. When the driving component is moved from a first position to a second position, the other tip of the driving component abuts against the plurality of ribs to drive a partial body of each of the plurality of umbrella ribs far away the main frame, so that the cap body dents inwardly from the periphery to the center to be an unfolded state.
