Abstract
The present invention discloses a periphery type space mesh equal-bottom expanding and gathering mechanism. A periphery type space mesh equal-bottom expanding and gathering device is formed by bias shear hinge mechanisms and equiangular double-stroke mechanisms. The equiangular double-stroke mechanisms are formed by the series connection of a plurality of bias shear mechanisms. A closed periphery type space mesh equal-bottom expanding and gathering mechanism is formed by a plurality of equiangular double mechanism coaxial arrays. The periphery type space mesh equal-bottom expanding and gathering mechanism is divided into a periphery type pyramid equal-bottom expanding and gathering mechanism and a periphery type ellipsoidal equal-bottom expanding and gathering mechanism due to the rod shape difference of bias shear hinge mechanisms. According to the periphery type space mesh equal-bottom expanding and gathering mechanism, a fixed bottom mode is used to complete expanding and gathering operations, the structure is simple, the reliability is high, the periphery type space mesh equal-bottom expanding and gathering mechanism and a spacecraft body can be coaxially arranged, a central passageway is not affected, an expanding and gathering ratio is large, the mechanism belongs to a parallel network structure, and the rigidity is strong. According to the periphery type space mesh equal-bottom expanding and gathering mechanism, an effective solution is provided for a non-sealed shielding or collection operation of a large diameter passage with the need of controlling opening and closing.
