Technical Field
[0001] The utility model relates to the technical field of flexible solar wings, in particular to a flexible solar wing elastic telescopic rod repeated deployment and retraction mechanism. Background Art
[0002] A flexible solar wing is a new type of solar panel. Compared with traditional rigid solar panels, it has better flexibility and lighter weight. This new type of solar panel can work at different shapes and angles, providing more efficient energy for satellites. The thickness of the flexible solar wing is very thin. The thickness of a single-layer flexible solar panel is only about 1 mm, which enables it to be stacked layer by layer inside the rocket fairing and launched simultaneously, greatly improving the effective utilization space of the rocket fairing and reducing the launch cost of a single satellite. The advantages of flexible solar wings include small envelope, light weight, modularity, etc. These characteristics enable it to perfectly meet the envelope requirements of flat-panel satellites for layered stacking, making it possible to launch a large number of satellites in a stacked manner. The emergence of flexible solar wings has had a significant impact on the satellite industry, indicating an important way for future low-Earth orbit commercial satellite launches. With the development of society, when the flexible solar wing needs to be deployed and retracted, a deployment and retraction mechanism is used.

The present invention solves the problems of large retraction envelope, heavy weight, and low specific power existing in the existing rigid and semi-rigid solar wings with a single-sided deployment method. The two retraction roller transmission devices of the present invention are fixedly arranged in parallel on the installation base.
