The invention discloses a lightweight fan-shaped unfolding mechanism and a spacecraft, and relates to the technical field of spacecrafts. The lightweight fan-shaped unfolding mechanism comprises a first connecting handle, a second connecting handle, an unfolding shaft, a shape memory alloy wire, a connecting plate and a framework, the tail end of the first connecting handle and the tail end of the second connecting handle are connected through the unfolding shaft, the shape memory alloy wire extends from the head end of the first connecting handle to the head end of the second connecting handle, the two ends of the shape memory alloy wire are fixedly connected to the first connecting handle and the second connecting handle, and the shape memory alloy wire is located below the unfolding shaft; the plurality of frameworks radiating outwards are rotationally connected to the unfolding shaft; connecting plates are arranged between every two adjacent frameworks, between the first connecting handle and the framework closest to the first connecting handle and between the second connecting handle and the framework closest to the second connecting handle. The technical problems that in the prior art, a solar panel of a spacecraft is complex in unfolding structure, prone to damage and incapable of being unfolded are solved.
本申请公开了一种轻量化扇形展开机构及航天器,涉及航天器技术领域。该轻量化扇形展开机构包括第一连接柄、第二连接柄、展开轴、形状记忆合金丝、连接板和骨架;第一连接柄的尾端和第二连接柄的尾端通过展开轴连接,形状记忆合金丝自第一连接柄的首端至第二连接柄的首端延伸设置,且形状记忆合金丝的两端固定连接于第一连接柄和第二连接柄,形状记忆合金丝位于展开轴的下方;多根向外辐射的骨架均转动连接于展开轴;相邻两根骨架之间,第一连接柄和最靠近第一连接柄的骨架之间,以及第二连接柄和最靠近第二连接柄的骨架之间均设置有连接板。本申请解决了现有技术航天器的太阳能帆板展开结构复杂,容易发生损坏而无法展开的技术问题。
