The invention discloses a space solar cell array sail surface unfolding mechanism, which belongs to the technical field of space solar cell arrays, and is characterized by comprising a connecting support module for connecting a satellite; the rotary unfolding module is mounted on the connecting and supporting module; the pressing and releasing module is positioned on the upper surface of the rotary unfolding module; the avoiding unfolding modules are located on the periphery of the rotary unfolding module; the avoiding unfolding module comprises M avoiding unfolding assemblies; the outer side edge of the pressing and releasing module is connected with one end of the avoiding and unfolding assembly through a disconnectable assembly. A mounting interface connected with the rotary unfolding module and the avoiding unfolding assembly is arranged on the connecting and supporting module; the other end of the avoiding unfolding assembly is connected with the connecting supporting module through a coil spring. And a flexible solar cell array sail surface is mounted in the rotary unfolding module. A system integration design scheme is adopted, and on the premise that the large folding-unfolding ratio, the large power mass ratio and the large power volume ratio are achieved, the advantages of being large in rigidity of the transmitting section and the on-orbit section, high in fundamental frequency and the like are achieved.
