AI Technical Summary
The existing spacecraft handrail structure is fixed and cannot adapt to the complex space environment, resulting in some areas failing to meet the envelope size requirements, which affects the efficiency and safety of astronauts' on-orbit maintenance.
Design a foldable quick-opening handrail, employing a limiting component, an unlocking shaft system, and an unlocking mechanism. The handrail can be quickly unlocked and unfolded through the cooperation of a deceleration disc spring with the unlocking shaft system and unlocking mechanism, ensuring convenient on-rail operation.
It enables rapid unlocking and deployment of the handrail during on-orbit operation, reduces the envelope size, facilitates astronauts' use in multiple situations, and improves the efficiency and safety of on-orbit maintenance.
