Abstract

The invention discloses an active high-rigidity locking combined mechanism of a flexible solar wing. The active high-rigidity locking combined mechanism comprises lower box body unfolding and lockingmechanisms and upper box body unfolding and locking mechanisms, wherein the lower box body unfolding and locking mechanisms are arranged on the two sides of the stretching mechanism respectively, andthe two sides of each lower box body unfolding and locking mechanism are each provided with one upper box body unfolding and locking mechanism; the lower box body unfolding and locking mechanism rotating shaft and the upper box body unfolding and locking mechanism rotating shaft are arranged at coaxial positions; when the lower box body unfolding and locking mechanism is unfolded, the upper box body unfolding and locking mechanism is unfolded and then locked. After being unfolded in place, the active mechanism can continuously act to eliminate a mechanism gap so as to increase the locking height, and has the advantage of high locking rigidity; the passive hinge is driven by the active mechanism to be unfolded and locked, and has the advantages of being simple and reliable. And after the active mechanism drives the passive hinge to be unfolded and locked, the cell array assembly can be separated under the action of the stretching mechanism so as to be unfolded. The mechanism is simple and reliable in structure, high in mechanism robustness, high in locking rigidity and small in folding envelope.

Description

technical field [0001] The invention relates to the field of aerospace technology, and relates to a locking combination mechanism. Background technique [0002] In the field of aerospace technology, the power demand of aircraft is increasing day by day. Flexible solar wings are generally used in occasions with large power generation and large deployment areas. Their length and width are relatively large, and their deployment and locking rigidity is relatively high. Moreover, due to the constraints of the envelope of the rocket fairing, the flexible solar wing should be folded as far as possible. Possibly small. The traditional solution adopts the configuration of male hinge and female hinge, which has disadvantages such as low rigidity. The flexible solar wing is a relatively cutting-edge space technology, and no related device to solve its high-stiffness deployment and locking has been investigated at home and abroad. Contents of the invention [0003] Aiming at the pr...
