A Spacecraft Parking Mechanism

Abstract

The invention relates to a spacecraft parking mechanism, and belongs to the field of space station cargo transportation. The spacecraft parking mechanism comprises an active end and a passive end. Theactive end comprises a three-jaw connecting mechanism, a spring push rod separation mechanism, a ball screw transmission mechanism, a worm and gear self-locking mechanism, an active end shell, an active end electric interface, a push disc and a fixed disc; the passive end comprises a passive end shell, a passive end disc spring assembly, a passive end electric interface and a passive end guide directional hole; after the active end is aligned with the active end under the driving of the space mechanical arm, the three-jaw connecting mechanism is rotated outwards to be opened; the active end continues to move towards the driven end until the active end electric interface is inserted into the passive end electric interface and is inserted in place; three clamping jaws of the three-jaw connecting mechanism rotate inwards to be closed, and locking and fixing are achieved. Mechanical connection between carried goods and a space station can be achieved under the assistance of the space mechanical arm, the goods can be parked in the space station, and stable parking can be kept for a long time. When separation is needed, low-impact reliable separation is realized.

Description

technical field [0001] The invention belongs to the field of space station cargo transportation, and relates to a space vehicle parking mechanism. Background technique [0002] With the development of my country's aerospace technology, the establishment and development of the space station is an important integration and embodiment of space technology. In the future, during the orbital flight of my country's space station, it will need the supply of space cargo resources, and it will need to transport ground materials to the space station to realize the docking of space cargo on the space station. [0003] The space cargo will be transported by the cargo spacecraft to the predetermined area of ​​the space, and the pallet system will be pulled out and transferred to the space station by the operation of the space station's mechanical arm, and it will be docked, docked, unlocked and separated from the space station cabin. [0004] In the prior art, most of the unmanned dockin...

AI Technical Summary

Problems solved by technology

In the prior art, due to the small pre-tightening force, the bearing capacity after the docking is completed cannot meet the needs of large-scale spacecraft connections, and after the pre-tightening force is applied to lock, the stress relaxation and mechanism creep problems caused by long-term locking are currently unresolved in technology
