Abstract

The invention discloses a panel antenna folding and unfolding unit and a two-dimensional folding and unfolding antenna mechanism. The panel antenna folding and unfolding unit comprises a plurality of panel antenna folding and unfolding units, large-span inter-plate hinges, positioning locking hinges and supporting trusses, wherein after the plurality of panel antenna folding and unfolding units are respectively and completely unfolded, all the antenna panels are in the same plane and are transversely and sequentially connected, the first antenna panels corresponding to two adjacent panel antenna folding and unfolding units are connected through two large-span plate hinges, the second antenna panels corresponding to every two connected panel antenna folding and unfolding units are connected through the positioning locking hinges, the third antenna panels corresponding to every two connected panel antenna folding and unfolding units are connected through the positioning locking hinges, the synchronizing mechanism of each panel antenna folding and unfolding unit is connected with the corresponding supporting truss, and every two adjacent supporting trusses are transversely and rotationally connected. The structure is reasonable, the unit unfolding stability is good, the folding rate is large, and the applicability is good.

Description

technical field [0001] The invention belongs to the technical field of aerospace vehicles, and in particular relates to a planar antenna folding unit and a two-dimensional folding antenna mechanism. Background technique [0002] In order to adapt to different space missions and meet the requirements of satellites for different purposes, many flat-panel multi-folding and unfolding mechanisms with complex structures have emerged. The two most representative folding structures are the foldable planar antenna structure and the multi-folding planar The structure of the sun wing. [0003] The structural forms and deployment principles of space-deployable antennas are also various. In order to meet the needs of information transmission and space detection, more and more large-scale space-deployable antennas are gradually appearing, which means that the requirements for antenna support truss mechanisms are increasing. Big. At present, the deployable antennas that have been applied...
