The invention discloses a two-degree-of-freedom solar cell array unfolding device. The two-degree-of-freedom solar cell array unfolding device comprises a root hinge, an unfolding arm, an unfolding synchronizing mechanism, a swing mechanism and an adapter flange; the unfolding arm is connected with a driving mechanism of a solar cell array through a root hinge, the other end of the unfolding arm is fixedly connected with the swing mechanism, an output shaft of the swing mechanism is fixedly connected with the solar cell array through the adapter flange, and the unfolding synchronizing mechanism is connected with the root hinge and the swing mechanism; and the unfolding synchronizing mechanism is used for controlling the unfolding synchronism of the root hinge, the unfolding arm, the swinging mechanism and the solar cell array. Through the unfolding arm and the swing mechanism, after the on-orbit unfolding function of the solar cell array is achieved, the two-degree-of-freedom rotation function of the solar cell array is achieved through the unfolding arm and the swing mechanism together with the driving mechanism.
