Passive unfolding and folding guide mechanism for flexible solar array

Abstract

The invention discloses a passive unfolding and folding guide mechanism for a flexible solar array. The passive unfolding and folding guide mechanism can guide flexible solar panels to be passively unfolded and folded and is simple in structure, stable in performance, convenient to mount and debug and high in adaptability. The passive unfolding and folding guide mechanism comprises rope collection mechanisms, guide steel wire ropes, hinge joint pieces and cables, wherein the hinge joint pieces are mounted on hinges between the flexible solar panels at intervals; the guide steel wire ropes are mounted on the back surfaces of the flexible solar panels, one ends of the guide steel wire ropes wind around the rope collection mechanisms on a fixed box board, and the other ends of the guide steel wire ropes penetrate the hinge joint pieces to be fixedly connected with a movable box board; the herringbone cables are mounted on two sides of the flexible solar array. The passive unfolding and folding guide mechanism can realize unfolding and folding guide functions of the flexible solar panels, adopts a passive guide principle, and can adapt to unfolding and folding processes without adoption of other control measures. The passive unfolding and folding guide mechanism is simple in structure, safe, reliable and excellent in performance, and can better restrain motion states of the flexible solar panels in the unfolding and folding processes.

Description

technical field [0001] The invention relates to the technical field of spacecraft solar wings, in particular to a passive flexible solar wing expansion and retraction guide mechanism. Background technique [0002] A large flexible solar wing contains a large number of flexible solar blankets, and the flexible solar blankets are usually connected by flexible hinges. Different from the traditional rigid solar wing, there is no linkage device between the hinges of the flexible solar wing, there are more degrees of freedom in the process of unfolding and retracting, and each flexible solar blanket has no fixed motion state. Therefore, it is necessary to increase the guiding device, so that the flexible solar blankets can be carried out in a certain order in the process of unfolding and retracting, so as to prevent the harmful swing of the flexible solar blankets. When the flexible solar blanket is unfolded, the pulling effect of the box board directly acts on the flexible solar...
