A space docking locking mechanism

Abstract

The invention discloses a space-docking locking mechanism, comprising passive ends and active ends, wherein the passive ends are installed on a target star docking face, the active ends are installedon a service star docking face, and each passive end is provided with a handle; each active end comprises a guide slot, a damper, a microswitch, a positioning seat, a motor, a speed reducer, a guide rail and a clamping jaw; each guide slot has an asymmetric V-shaped structure; one end of each guide slot is hinged with one end of the single clamping jaw, and the other end of the guide slot is connected with the corresponding damper; the bottom ends of the guide slots are connected with the guide rails; when moving along the guide rail, the bottom ends of the guide slots can touch the microswitches and start the motors, so that the clamping jaws are driven to be closed with the guide slots for catching the handles until the handles are tightly pressed on the positioning seats.

Description

technical field [0001] The invention relates to a space docking locking mechanism, which belongs to the technical field of space docking and on-rail operation. Background technique [0002] At present, the following methods are mainly used for space capture or docking at home and abroad: 1) The general-purpose multi-joint manipulator completes the capture and docking. The manipulator system is complex, the cost is high, and the connection stiffness between the two satellites is small after docking. It is mainly used for satellite maintenance, etc. Space operation; 2) The docking of the manned spacecraft and the space station adopts the "isomorphic" peripheral inversion docking mechanism, which is a sealed docking, forming a sealed channel for astronauts and cargo transmission; 3) Flying net type, three-claw type docking Mechanism problems include: flying net capture cannot be separated, mainly used for dragging off the track, etc. The three-claw capture scheme needs to arran...

[0002] At present, the following methods are mainly used for space capture or docking at home and abroad: 1) The general-purpose multi-joint manipulator completes the capture and docking. The manipulator system is complex, the cost is high, and the connection stiffness between the two satellites is small after docking. It is mainly used for satellite maintenance, etc. Space operation; 2) The docking of the manned spacecraft and the space station adopts the "isomorphic" peripheral inversion docking mechanism, which is a sealed docking, forming a sealed channel for astronauts and cargo transmission; 3) Flying net type, three-claw type docking Mechanism problems include: flying net capture cannot be separated, mainly used for dragging off the track, etc. The three-claw capture scheme needs to arrange the docking mechanism in the center of the docking surface, and the existing nozzle, filling interface and other follow-up operating equipment Installation position interference; 4) other space capture docking mechanism

[0003] Existing problems include: the impact force is large during the docking process, which will damage the spaceborne scientific instruments; the docking accuracy is low, and it cannot meet the follow-up high-precision on-orbit maintenance and operation such as on-orbit refueling; the structure is complex, heavy, and costly.
