Low-power-consumption, high-integration and high-reliability space adhesion device

Abstract

The invention provides a low-power-consumption, high-integration and high-reliability space adhesion device, which comprises a connecting assembly which is used for connecting with an active platform;a buffer mechanism is used for buffering normal impact of the device on a target and is connected with the connecting assembly; a force bearing structure which is connected with the buffer mechanism;a front-end motor driving mechanism which is connected with the buffer mechanism and is in contact with the tail-end transmission mechanism; a tail end transmission mechanism which is used for adhering a target, is connected with the force bearing structure and is in contact with the front end motor driving mechanism; and a sensing and electric control part which is arranged on the buffer mechanism and is used for controlling the whole adhesion device. The space adhesion device has the advantages that all components are combined, integration of pressing, separating and buffering of the spaceadhesion device on the driving platform is achieved, tangential loading during collision pre-pressing can be achieved, and flattening and centripetal loading of a space four-rod mechanism can be achieved through a differential mechanism composed of the space adhesion device and the two double-sliding-block mechanisms.

Description

technical field [0001] The invention relates to the field of space manipulation research, in particular to a space-adhesive claw device with low power consumption, high integration and high reliability for precise space manipulation. Background technique [0002] In recent years, with the increase in the number of spacecraft used, on-orbit maintenance of spacecraft, on-orbit control, recovery of invalid satellites, and controlled fall of medium and large space debris have become or will become research hotspots. The traditional capture methods of space targets mainly include mechanical arm grabbing and net capturing. The use of the above methods has its limitations, especially the requirement that the target volume should not be too large. However, spacecraft such as failed satellites, medium and large space debris, or their wreckage are often large in size, so traditional actuators are not suitable for this target.
