The invention provides a distributed Y-shaped antenna array unfolding device suitable for a hexagonal satellite, and the device comprises three groups of antenna array unfolding assemblies which are uniformly disposed on the hexagonal satellite in the circumferential direction, and each antenna array unfolding assembly comprises a root support, a first antenna frame, a second antenna frame, and an unfolding locking assembly. One end of the first antenna frame is rotationally connected with the root support through the unfolding locking assembly to form a first rotating joint, and the other end of the first antenna frame is rotationally connected with the second antenna frame through the unfolding locking assembly to form a second rotating joint; the first antenna frame is provided with a pressing and releasing assembly and a restraining and releasing assembly which are used for restraining. According to the invention, simplification of each movable joint and independence and self-adjustment of each rotating joint are realized through the unfolding locking assembly, reduction of system complexity is facilitated, the folding and unfolding states and the unfolding time sequence of the antenna array unfolding assembly are accurately controlled through the compression release assembly and the constraint release assembly, and improvement of adaptability and expansibility is facilitated.

    本发明提供了一种适用于六边形卫星的分布式Y形天线阵展开装置,包括三组周向均匀设置在六边形卫星上的天线阵展开组件,天线阵展开组件包括根部支座、第一天线框架、第二天线框架以及展开锁定组件;第一天线框架的一端通过展开锁定组件与根部支座转动连接形成第一转动关节,另一端通过展开锁定组件与第二天线框架转动连接形成第二转动关节;第一天线框架上设置有用于约束的压紧释放组件和约束释放组件。本发明通过展开锁定组件实现各个活动关节精简,转动关节均独立并可自行调节,有助于降低系统复杂度,通过压紧释放组件和约束释放组件,精准控制天线阵展开组件的收拢和展开状态以及展开时序,有助于提高适应性和拓展性。
