Problems solved by technology

[0003]Currently, the known capturing and locking mechanism has a slow capturing speed, and there are risks in the capturing process; the product interchangeability is poor, and the lock handle is relatively captured and locked in the locked state When the device has a position deviation, the locking force of the mechanism has a large deviation; when the connection stability is insufficient and the locking state is maintained for a long time, the connection force will decrease due to the change of the structural deformation

Embodiment Construction

[0054] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0055] In the embodiment of the present invention, the schematic diagram of the capture and locking mechanism provided in this example is as follows figure 1 As shown, it includes a capture and lock device 1000 connected to the active end of the separation mechanism and a lock handle 2000 connected to the passive end of the separation mechanism, wherein the capture and lock device 1000 includes an actuator 1100 and a drive device 1200, and the input end of the actuator 1100 is connected to the The output end of the driving device 1200 is connected. In this example, by designing the actuator 1100, the movement principle between a pair of symmetrical planar six-bar mechanisms is used to capture, draw and lock the lock handle 2000, so as to realize the active end of the corresponding separation mechanism. The capturing, closing and l...

Abstract

A capturing-locking mechanism includes a capturing-locking device connected to an active end of a separating mechanism and a locking handle connected to a passive end of that separating mechanism. Thecapturing-locking device comprises an actuator and a driving device. The output end of the driving device is connected with the input end of the actuator. The actuator captures, pulls near and locksthe lock handle by a pair of rotating pairs and moving pairs between symmetrical planar six-bar mechanisms, thereby realizing the unlocking and releasing of the active end to the passive end of the separating mechanism. The capturing-locking mechanism provides characteristics such as rapid capture and stable locking for the connection and separation mechanism, and improves the capture reliability,interchangeability and connection stability of the connection and separation mechanism.

Description

technical field [0001] The invention relates to the technical field of space separation mechanisms, in particular to a capturing and locking mechanism that can provide the space separation mechanism with the functions of repeatedly capturing, drawing in, locking, unlocking, and releasing. Background technique [0002] The capture and locking mechanism is mainly used in the space connection and separation mechanism, so as to provide implementability guarantee for spacecraft on-orbit assembly, functional reconstruction, energy supply, information interaction and other functions. [0003] At present, the capture speed of the known capture and lock mechanism is slow, and there are risks in the capture process; the product interchangeability is poor, and when there is a position deviation of the lock handle relative to the capture and lock device in the locked state, the locking force of the mechanism has a large deviation; Insufficient stability, when the locked state is maintai...
