The invention provides a light and high-storage-ratio on-orbit truss unfolding structure. The light and high-storage-ratio on-orbit truss unfolding structure comprises triangular frames, lower supporting rods, drive torsional springs, an upper supporting rod and limiting leaf springs. When the truss structure is in the folded state, the upper supporting rod and the lower supporting rods are folded in the edge length direction of the triangular frames in the manner that folding is conducted at the positions of the drive tornsional springs, and are driven by the tornsional springs to be unfolded after the truss structure is on orbit, and mechanical limiting parts and the leaf springs between the upper supporting rod and the lower supporting rods are locked at the same time at the completely-unfolded positions after the unfolding process is finished. The light and high-storage-ratio on-orbit truss unfolding structure solves the problem that truss structures on part of satellites need to be unfolded on orbit. The truss unfolding structure has the high storage ratio (7%), and meanwhile the unfolding structure has the beneficial effects of being light in weight, high in rigidity and reliability, and the like.
