Abstract

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.

Description

Technical field[0001]The present invention belongs to the field of satellite technology, and more particularly to a two-degree-of-freedom solar battery array unfolding device.Background technique[0002]The satellite solar cell array is generally realized by the unfolding device. After the deployment is in place, the drive mechanism drives the entire solar battery array to the day-order. Generally, the solar cell array only needs a degree of freedom, but for some of the satellite with special application purposes, the incident angle of the battery array in a track cycle is large, and the single freedom has not guaranteed good sun light. The incident angle requires two degrees of freedom to rotate to achieve the sustainable purpose. At present, all kinds of spacecrafts, solar cells in my country, the solar cells are plural in a single degree of freedom, and generally unfolding only the solar cell array in the track exhibition and the locked function.[0003]At the same time, the current ...
