Description

Technical Field

The umbrella structure consists of an umbrella skeleton, an umbrella surface, and an umbrella handle, and is a retractable and deployable structure. To date, umbrella technology has been quite mature, and existing umbrella structures have good mechanical stability.

[0003] A tensegrity structure is a special structural form, a new type of rod-and-cable network structure, and also a deployable structure. A tensegrity structure forms a stable force system by applying prestress so that the tensile forces in the structure are evenly distributed. Since the tensile forces in this structure can effectively resist external loads such as wind force and snow load, it has irreplaceable advantages in lightweight structure design.

[0004] The umbrella-shaped tensegrity structure is a typical form in tensegrity structures, usually adopting radially distributed rods and cables to form a three-dimensional system with spatial stability. This structure completes the tensioning of the overall structure through the combined action of rigging at the central position and support members, so that the entire structure remains stable under the action of its own weight and external loads.

At the same time, it is easy to install, move, and disassemble. In contrast, the umbrella frame structure corresponding to Embodiment B has an overly large opening angle; Embodiment C reduces the number of circular array movements, but the stability of the umbrella frame structure is difficult to meet actual requirements; the multi-layer structure obtained by increasing the complexity in Embodiment D further enhances the strength, but has a high structural complexity, increased material and installation costs, and is not suitable for scenarios that require quick setup and convenient movement.
