Abstract

The invention discloses a modular expandable antenna mechanism based on a symmetrical structure tetrahedral combination unit. The modular expandable antenna mechanism is formed by a plurality of expandable antenna modules, each two adjacent expandable antenna modules are connected through a first face plate at the bottom portion of one of the expandable antenna modules and a second face plate at the bottom portion of the other one of the expandable antenna modules, the first face plate and the second face plate are connected through a hooke hinge, a first face plate and a second face plate which are not connected at the bottom portions of each two adjacent expandable antenna modules are connected through a first synchronization rod, the middle portions of the rod bodies of the first synchronization rods can be folded, and the first synchronization rods, the first face plates and the second face plates are rotationally connected. The expandable antenna modules of the modular expandableantenna mechanism are connected through the hooke hinges to achieve relative posture adjustment between the modules, the structure is simple, the processing and manufacturing cost and the installationdifficulty are low, and a large-scale expandable antenna mechanism with any caliber and a high folding rate can be formed.

Description

Technical field [0001] The present invention relates to the technical field of a space deployable mechanism, in particular to a modular deployable antenna mechanism based on a symmetrical structure tetrahedral combined unit. Background technique [0002] Aerospace technology occupies an important position in my country's scientific and technological development strategic plan. With the implementation and deepening of a series of major aerospace science and technology projects such as deep space exploration, manned spaceflight, and large-scale carrier rockets, the application requirements for large-scale institutions with expandable performance have become more urgent. In recent years, large-scale deployable mechanisms have been used in deployable masts, antennas, etc. due to their excellent performance, such as the consistency of structural geometric units, repeatability, high rigidity, flexible geometric design features and high surface accuracy. Solar panels have been widely us...
