Array type folding and unfolding antenna mechanism based on rectangular pyramid unit

Abstract

The invention discloses an array type folding and unfolding antenna mechanism based on a rectangular pyramid unit. The rectangular pyramid unit is composed of a top faceplate, a first bottom faceplate, a second bottom faceplate, a third bottom faceplate, a fourth bottom faceplate, four first bottom connecting rods, four second bottom connecting rods and four web members. According to the mechanism, a plurality of groups of tightly connected array type folding and unfolding antenna mechanisms are vertically and transversely combined in an array form, and every two top faceplates of the rectangular pyramid units after an array is formed are connected through a top end first connecting rod and a top end second connecting rod. According to the array type folding and unfolding antenna mechanism, by adding driving at a rotating pair, the faceplates are tightly leaned against one another, the shape of the faceplates is regular, and the faceplates are consistent in posture and are located in the same plane. The array type folding and unfolding antenna mechanism based on the rectangular pyramid unit has the comprehensive advantages of being high in rigidity, high in folding rate, high in supporting performance, adjustable in aperture size and the like.

Description

Technical field [0001] The present invention relates to the technical field of the discrete antenna mechanism, and in particular, a array of array-based fold antenna mechanism based on a four-prism unit. Background technique [0002] At present, the competition in the aerospace sector is more fierce, in order to transport various mechanical equipment to space in order to further carry out scientific research, the need for space-free institutions is an inevitable trend of future development. The space can be exhibited by the unique advantage of transportation, easy to transport, easy to install, and the quality of quality aerospace projects such as space rail construction and satellite communications are important. [0003] With the rapid development of space technology, higher requirements for high precision, large caliber, light massization, can have multiple basic units to achieve an adjustment and flexible transformation of antenna volume, quantity, and size. . The exhibible m...
