A star in-orbit docking and locking device

Abstract

A satellite-to-satellite on-orbit docking and locking device is used for docking a service satellite with a non-cooperative target satellite, and comprises a guide structure, a locking device, and a positioning pin, wherein the guide structure is mounted on the service satellite, the guide structure comprises a tapered surface for eliminating the deviation in the axial tilt angle of docking posture with the non-cooperative target satellite, the guide structure further comprises a sectioned notch with a bevel edge, and the sectioned notch is used for correcting the deviation in circumferential rotation angle with respect to a docking ring of the non-cooperative target satellite; the locking device is mounted on the service satellite, the locking device comprises a cam wheel, two clamping claws stretch out from the edge of the cam wheel, and a bayonet is formed between the two clamping claws, so as to restrain the inner edge of the docking ring of the non-cooperative target satellite. The positioning pin is arranged on the guide structure and is matched with a positioning pin hole on the docking ring of the non-cooperative target satellite, so as to precisely guide and restrain the relative position between the service satellite and the non-cooperative target satellite. The satellite-to-satellite on-orbit docking and locking device is applicable to all satellites with the docking ring; and the satellite-to-satellite on-orbit docking and locking device is substantially wide in application range, including large satellites, small satellites, and micro satellites.

Description

technical field [0001] The invention relates to a spacecraft track equipment, in particular to a star in-orbit docking and locking device. Background technique [0002] Generally speaking, after the satellite is launched into the sky, its hardware cannot be repaired, so the previous satellite design required high reliability and tried to succeed at the first time. With the development of astronauts going to space and space robotics, services such as on-orbit maintenance and fuel supply have become possible, and satellites can be maintained on-orbit. However, the maintainability of the satellite itself still largely depends on the design of its mechanical interface, such as whether it has a capture or docking interface, whether the structural opening has a high degree of openness, whether the operation is accessible, and whether the ORU unit (Orbital Replaceable Units, on-orbit replaceable unit) whether the interface adopts modular packaging, whether it can be plug-and-play,...

AI Technical Summary

Problems solved by technology

[0006] The present invention solves the problem that the existing satellite in-orbit docking device connected to the nozzle is not suitable for small satellites or tiny satellites, and needs other structures and sensor auxiliary support.
