Abstract

The invention discloses a novel flexible solar cell array unfolding device and belongs to the technical field of civil aerospace engineering. The device is composed of a synchronous extending mechanism and a central driving mechanism. The synchronous extending mechanism is composed of a flexible solar cell array sailboard, a driving mechanism, an unfolding mechanism, a synchronizing mechanism and a locking mechanism, wherein the flexible solar cell array sailboard uses five annular amorphous silicon films, the driving mechanism uses a method that torsion spring driving and servo motor driving are combined, a torsion spring at the hinge position can complement driving torque required in an unfolding process, the unfolding mechanism uses a gap hinge, a driving pin shaft of the gap hinge is replaceable, the synchronizing mechanism uses a steel wire rope to drive a linkage mechanism, and the locking mechanism uses a cam pin type locking mechanism. The novel flexible solar cell array unfolding device provides a flexible solar cell array unfolding method, solves the problems that a traditional solar cell array is complex in structure, small in folding ratio and low in work reliability, fully utilizes the material characteristics of a flexible substrate and improves the power generation efficiency of a solar cell array and the use reliability of the solar cell array.

Description

technical field

[0001] The invention belongs to the technical field of civil aerospace, and in particular relates to a novel flexible solar battery array deployment device. Background technique

[0002] With the development of aerospace technology, the volume and scale of spacecraft are increasing day by day, carrying more and more payloads, and the energy demand is also increasing exponentially. The existing rigid foldable solar cell array can no longer meet the power requirements.

[0003] Flexible substrate solar cell arrays, especially thin-film solar cell arrays, have become the development trend of a new generation of solar cell arrays because of their small mass, high power generation efficiency, and high specific power. Therefore, it is of great significance to study a new flexible solar cell array deployment mechanism with high folding ratio and high reliability to improve the power generation of spacecraft on orbit.

[0004] According to the data of flexible solar...
