The invention discloses a flexible solar wing unfolding mechanism with a high unfolding-folding ratio. The flexible solar wing unfolding mechanism comprises a bottom plate, a shear fork rod assembly, a top plate and a solar blanket assembly; the unfolding mechanism further comprises a driving assembly integrated on the bottom plate; the driving assembly is provided with a driving motor and a transmission gear, and the transmission gear extends to the upper part of the bottom plate; and the driving assembly is in transmission connection with the shear fork rod assembly through the transmission gear and drives the shear fork rod assembly to be unfolded so as to drive the solar blanket assembly to be unfolded. The unfolding mechanism is simple in structure, high in reliability and small in mass; most structural parts in the mechanism are made of spaceflight-grade hard aluminum alloy and carbon fiber composite materials, the mechanical structure is simple and not numerous and jumbled, and the structural parts are subjected to lightweight design improvement on the premise that the strength and vibration requirements are guaranteed; and the unfolding mechanism is low in manufacturing cost and material price, structural parts are simple in structure and convenient to manufacture, the shear fork rod assembly drives the solar blanket assembly to move, and the unfolding mechanism has the advantages of being light in weight, small in folding size, large in unfolding span and high in unfolding and folding ratio.
