Problems solved by technology

China started late in research on deployable antennas. At present, the research on deployable mechanisms mainly focuses on the kinematics and dynamics of the mechanism, but there are not many designs of modular units that make up space deployable antennas. In order to meet the ever-increasing demands in space research, designing a new type of deployable mechanism composed of modular units has great development prospects

Abstract

The invention discloses a modular curved surface deployable antenna mechanism based on single-degree-of-freedom deployable units. The deployable antenna mechanism is composed of a plurality of deployable antenna modules, wherein the two adjacent deployable antenna modules are rotatably connected by means of a first disc chuck at the bottom part of one deployable antenna mechanism and a second discchuck at the bottom part of the other deployable antenna mechanism, a first disc chuck and a second disc chuck which are not connected at the bottom part of the two adjacent deployable antenna mechanisms are connected by means of a first synchronization rod, the middle portion of the first synchronization rod can be folded, and the first synchronization rod is rotatably connected with the first disc chuck and the second disc chuck. The deployable antenna mechanism provided by the invention can realize direct and complete folding of the modules, has the advantages of simple structure, low processing and manufacturing cost and low installation difficulty, and can form large-scale deployable antenna mechanism of any aperture with a high folding rate.

Description

technical field [0001] The invention relates to the technical field of space deployable mechanisms, in particular to a modular curved surface deployable antenna mechanism based on a single-degree-of-freedom deployable unit. Background technique [0002] With the rapid development of aerospace technology, aerospace technology occupies an important position in the strategic planning of my country's scientific and technological development, and the demand for large-scale expandable institutions in aerospace engineering is more urgent. However, due to the limitation of storage capacity in aerospace engineering, the demand for deployable antennas with high stretchability, high stiffness, and high stability is becoming more and more urgent. The expandable mechanism is in a folded state during storage and transportation, and when it is placed in the working track and ready, the driving device can make it unfold into a predetermined working state. At present, the application of dep...
