The invention belongs to the technical field of aerospace equipment, and discloses an unfolding mechanism and a spacecraft, and the unfolding mechanism is used for winding and unwinding a curling arm and comprises a bearing part, a rotating shaft and a plurality of guide parts. The rotating shaft is rotationally arranged on the bearing piece, one end of the curling arm is fixed to the rotating shaft, and the rotating shaft is used for winding and unwinding the curling arm. The multiple guiding parts are distributed on the bearing piece along the periphery of the rotating shaft and used for providing guiding in the winding and unwinding process of the winding arm. The curling arm is wound through the rotating shaft, and the curling arm can be unfolded or folded by rotating the rotating shaft, so that the solar wing adopting the unfolding mechanism is simple in overall structure, small in size and capable of meeting the space requirement of a small spacecraft. Comprising the unfolding mechanism is small in size and can meet the requirement of miniaturization design.

    本发明属于航天设备技术领域,公开了一种展开机构及航天器,展开机构用于收放卷卷曲臂,其包括承载件、转动轴以及多个导向部。转动轴转动设置于承载件上,卷曲臂的一端固定于转动轴上,转动轴用于收放卷卷曲臂。多个导向部沿转动轴的外周分布于承载件上,多个导向部用于在卷曲臂收放卷的过程中提供导向。通过转动轴卷绕卷曲臂,转动转动轴即可展开或收拢卷曲臂,从而使得采用上述展开机构的太阳翼整体结构简单、体积小,能够满足小型航天器的空间需求。包括上述展开机构的航天器,体积小,可满足小型化设计的需求。
