The invention discloses a repeatable fan-shaped unfolding mechanism based on shape memory alloy driving. The problems that in the prior art, an antenna unfolding structure of a spacecraft is complex, is prone to damage and cannot be unfolded are solved. The shape memory alloy driving-based repeatable fan-shaped unfolding mechanism comprises a shell, an unfolding shaft, a framework, a connecting plate and a shape memory alloy strip, the shell is configured to accommodate the framework, the connecting plate and the shape memory alloy strip; the two ends of the unfolding shaft are fixedly connected with the two side walls of the shell correspondingly. The plurality of frameworks radiating outwards are rotationally connected to the unfolding shaft; connecting plates and shape memory alloy strips are arranged between every two adjacent frameworks and between the bottom of the shell and the framework closest to the bottom of the shell; each shape memory alloy strip is of a bent structure. Therefore ...
