The satellite solar cell array unfolding mechanism comprises a servo motor which is fixed on a satellite structure frame; the first fixing rod is fixedly connected with the satellite structure frame; the first end of the first movable rod is pivotally connected with the first end of the first fixed rod; the first end of the second movable rod is pivotally connected with the second end of the first fixed rod; the second fixing rod is fixedly connected with the satellite solar cell array; the first end of the third movable rod is pivotally connected with the first end of the second fixed rod; the first end of the fourth movable rod is pivotally connected with the second end of the second fixed rod; the second end of the first movable rod is pivotally connected with the second end of the third movable rod; the second end of the second movable rod is pivotally connected with the second end of the fourth movable rod; the middle parts of the second movable rod and the third movable rod are pivotally connected; an output shaft of the servo motor drives the first movable rod to rotate with the first pin shaft as the center, and therefore the satellite solar cell array is driven to be unfolded and folded relative to the satellite structure frame.
