Abstract

The invention belongs to the technical field of spaceflight, and particularly relates to an inner-gear-type non-cooperative target locking mechanism. The inner-gear-type non-cooperative target lockingmechanism comprises a supporting shell, a bearing bush, a circular ring assembly, an inner toothed ring, multiple connecting pillars, locking connecting rods, pressing blocks, connecting screws and torsional springs, wherein the bearing bush is fixedly connected to the middle upper end of the inner wall of the supporting shell, the inner toothed ring is rotatably connected into the bearing bush,the upper end of the inner toothed ring is fixedly connected with the circular ring assembly through the connecting pillars, the upper end inside the supporting shell is fixedly connected with multiple lugs, all the lugs are hinged to the middle ends of the locking connecting rods through the connecting screws respectively, the connecting screws are sleeved with the torsional springs, the two endsof each torsional spring are connected with the supporting shell and the locking connecting rods respectively, the pressing blocks are fixedly connected to the upper ends of the locking connecting rods, the lower ends of the locking connecting rods are slidably connected with the inner side of the circular ring assembly, and the inner side of the circular ring assembly is fixedly connected with multiple convex lugs. By means of the inner-gear-type non-cooperative target locking mechanism, catching and releasing of a target can be achieved, and the stability of the target and the accuracy of the attitude are guaranteed.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a locking mechanism, more specifically an internal gear type non-cooperative target locking mechanism. Background technique [0002] The non-cooperative target docking technology is different from the cooperative target docking technology. Its docking target is a satellite without a specific docking interface. Generally, the AKM nozzle of the satellite's apogee recoil engine is selected as the docking interface. Currently designed docking mechanisms for non-cooperative targets lack locking mechanisms, poor connection stiffness, and poor capture reliability. Contents of the invention [0003] The purpose of the present invention is to solve the problems that the existing non-cooperative target docking mechanism is difficult to ensure the stability of the target and the accuracy of the posture after capturing the target, the connection stiffness is poor, and there ...
