Abstract

The invention discloses a fan-shaped solar wing repetitive folding and unfolding mechanism. Most spacecrafts adopt a one-time unfolding locking mechanism, and thus the stability is influenced when the spacecrafts change an orbit or adjust and control the attitude. A supporting frame component is respectively connected with the inner wall of a movement guide plate, and the inner wall of a stationary plate; one end of the stationary plate is fixed with a stationary plate link span; two ends of the stationary plate link span are respectively hinged to a spacecraft body; a driven pulley and a driving pulley are connected by a conveyor belt; the other end of the stationary plate is hinged to the center of the driven pulley; the rim of the driven pulley is hinged to the one end of the movement guide plate; the movement guide plate is fixed with a wedge; two spring installation seats are fixed on the stationary plate; the inner side of each spring installation seat is connected with a clamping block through a locking-unlocking spring; the clamping block close to the spacecraft body is hinged to the stationary plate, and the other block is hinged to a locking-unlocking sliding block which is connected with the stationary plate in a sliding way. Repetitive folding and unfolding of a fan-shaped solar wing can be realized by means of the fan-shaped solar wing repetitive folding and unfolding mechanism.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a fan-shaped solar wing, in particular to a fan-shaped solar wing repeating folding mechanism. Background technique [0002] Solar wings are a major form of space power supply for spacecraft. At present, most spacecraft solar wings use rigid substrates, and their deployment often adopts a one-time deployment and locking mechanism, that is, the solar wings are folded and folded in the fairing during the launch phase, and they are unfolded and locked to the working state at one time after orbiting. Since the solar cell substrate is a rigid substrate, its weight and volume are relatively large, and corresponding requirements are put forward for the carrying space. When the spacecraft performs orbit change or attitude adjustment control, the flutter of the deployed solar panel itself will disturb the posture of the spacecraft body and affect the attitude stability of the spacecraft...
