Embodiment Construction
[0029] like Figure 1-Figure 4As shown, the scissors linkage double-layer ring truss deployable antenna mechanism includes N inner layer folding units A, N outer layer folding units B and N inner and outer layer connecting truss assemblies C; each inner layer folding unit A Closely arranged, the adjacent inner layer folding units are connected by sharing two inner layer faceplates, thus forming the inner layer ring truss assembly, and the inner layer ring truss assembly is a multi-faceted ring truss structure after unfolding; each outer layer folding unit B Closely arranged, the adjacent outer layer folding and unfolding units are connected by sharing two outer layer faceplates to form an outer layer ring truss assembly. After the outer layer ring truss assembly is unfolded, it becomes a multi-faceted ring truss structure; The ring truss can be deployed in the antenna mechanism. The inner ring truss assembly and the outer ring truss assembly are concentrically arranged, and th...
