Description

technical field [0001] The invention relates to a deploying and folding device for aerospace vehicles, in particular to a deploying device with high precision, miniaturization and large torque output. Background technique [0002] At present, the known devices for deploying satellite solar wings in place are good both in terms of the maturity of the design technology and the application of the product. However, the prior art is still not satisfied with the deployment device that is suitable for the environment of extreme high and low temperature, high vacuum and lunar dust on the lunar surface, and has high transmission precision and light mechanism weight. [0003] In addition, domestic spacecraft solar cell wing deployment adopts a one-time continuous deployment mechanism (commonly known as passive deployment mechanism), which cannot meet the load of large-area solar wings. [0004] Prior art, its weak point is as follows: [0005] 1. It cannot meet the requirements of h...
