Abstract

The invention discloses a modular extendable antenna mechanism based on a tetrahedron combination unit with a symmetrical structure. The extendable antenna mechanism is composed of a plurality of extendable antenna modules, and two adjacent extendable antenna modules pass through one of the extendable antenna modules. The first faceplate at the bottom is connected to the second faceplate at the bottom of another extendable antenna module, and the first faceplate and the second faceplate are connected through a Hooke hinge, and the unconnected first faceplate at the bottom of two adjacent extendable antenna modules The faceplate and the second faceplate are connected by the first synchronization rod, the middle part of the rod body of the first synchronization rod can be folded, and the first synchronization rod is rotatably connected with the first faceplate and the second faceplate; the module of the extendable antenna mechanism provided by the present invention The modules are connected by a Hooke hinge, which can realize the relative posture adjustment between the modules, and has the advantages of simple structure, low manufacturing cost and low installation difficulty, and can form a large-scale extendable antenna mechanism with a high folding rate of any caliber.

Description

technical field [0001] The invention relates to the technical field of space expandable mechanisms, in particular to a modular expandable antenna mechanism based on a tetrahedron combination unit with a symmetrical structure. Background technique [0002] Aerospace technology plays an important role in the strategic planning of my country's scientific and technological development.
