The invention discloses a micro-nano satellite unfolding mechanism which comprises a satellite body, a solar wing assembly, a data transmission antenna assembly, an electric detection antenna assembly, a first rope limiting piece, a first binding rope and a first cut-off mechanism. The solar wing assembly comprises a sailboard swinging mechanism, a solar sailboard and a sailboard 180-degree unfolding mechanism; first rope limiting pieces are arranged on the solar panel, the data transmission base bracket and the electric detection connecting rod; the first binding rope is wound on the outer side of the satellite body through the first rope limiting piece and enables the solar wing assembly, the data transmission antenna assembly and the electric detection antenna assembly to be kept in a folded state. The first cut-off mechanism is arranged on the satellite body, and the first cut-off mechanism and the first binding rope are arranged correspondingly. The solar wing, the data transmission antenna and the electric detection antenna can be rapidly folded and unfolded, the overall related range is large, the structure is simple, cost is low, large-scale production is facilitated, disassembly and assembly are convenient, the structure is stable and reliable, the device can adapt to high and low temperature and other complex environments, and space is saved.

    本发明公开了一种微纳卫星展开机构,包括卫星主体、太阳翼组件、数传天线组件、电侦天线组件、第一绳索限位件、第一绑绳和第一切断机构;太阳翼组件包括帆板摆动机构、太阳能帆板和帆板180度展开机构;太阳能帆板、数传底座支架和电侦连杆上均设有第一绳索限位件;第一绑绳通过第一绳索限位件绕设于卫星主体外侧并使太阳翼组件、数传天线组件和电侦天线组件保持折叠状态;第一切断机构设置于卫星主体上,且第一切断机构与第一绑绳相对应设置。本发明可以实现对太阳翼、数传天线、电侦天线的快速收拢和展开,整体涉及范围大、结构简单、成本低便于规模生产、拆装方便、结构稳定可靠、能适应高低温等复杂环境、节省空间。
