Abstract

The invention provides a satellite solar cell sailboard which comprises a sailboard body and an elastic unfolding mechanism, the sailboard body is mounted on a satellite bearing plate and has a foldedstate and an unfolded state, the elastic unfolding mechanism enables the sailboard body in the folded state to be unfolded, and the sailboard body comprises M sub-sailboards connected in sequence. The bottommost sub-sailboards are rotationally connected with the force bearing board, the sub-sailboards are rotationally connected, and the M sub-sailboards are sequentially stacked on the force bearing board in a folded state; when the sailboard body is in a folded state, the external pressing and releasing mechanism provides constraint to keep pressing, and after the pressing and releasing mechanism acts to release the pressing constraint, the sailboard body can be unfolded under the action of the elastic unfolding mechanism. The sailboard is simple and reliable in structure, flexible in design, small in envelope in a folded state and large in expandable area, and can be automatically locked after being expanded; unfolding of the sailboard body is achieved through elastic potential energy accumulated by the elastic unfolding mechanism, no power source or hydraulic driving piece exists, and the complexity of the unfolding mechanism can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of aerospace satellites, and in particular relates to a satellite solar cell sailboard. Background technique [0002] Satellites in space mainly use solar panels to provide energy for them. The larger the area of ​​the panels, the more energy they can provide. In order to increase the area of ​​the sailboard as much as possible and meet the envelope constraints of the rocket, the sailboard is generally designed as a structure with a folded state and an unfolded state. The sailboard is in a retracted state on the ground and during launch, and then unfolded in space after being launched into orbit. [0003] The deployment mechanism that drives the sailboard deployment is the core part, and the reliability of the deployment mechanism directly affects the performance of the satellite as a whole. According to different driving methods, the unfolding mechanism can be divided into micro-motor driven, hydraulic or...
