Integrated docking and adding device and docking method

Abstract

The invention discloses an integrated docking and adding device. The integrated docking and adding device comprises a driving part and a driven part, and a layout form of a center and a periphery in a circle is adopted; a center rod is flexible, and after soft docking is realized, three groups of rigid rods uniformly distributed at the periphery are in rigid connection; when the initial docking of the flexible center rod is completed, and declination of two spacecrafts in the pitching/yaw direction is corrected, declination of the spacecrafts at lateral (radial) positions is corrected; when the initial docking of three side rods is completed, the rotating declination of the two spacecrafts is corrected, and the rigidities of the two connected spacecrafts are provided; the center rod has functions of limitation and control in extending movements and retracting movements, and after the center rod extends in place, a feedback signal is provided by a Hall proximity switch; the center rod and peripheral rods are unlocked by electromagnets. According to the integrated docking and adding device, the Hall proximity switch is arranged at the top end of the flexible rod, so that an erroneous judgment of locking is prevented, and a driven end is guaranteed to be passive.

Description

technical field [0001] The invention relates to a spacecraft docking mechanism, in particular to a spacecraft docking and supplementary integration device. Background technique [0002] With the improvement of space technology and the expansion of application requirements, due to the limitation of carrying capacity, large space facilities cannot be launched into space at one time, so the demand for on-orbit assembly and docking of spacecraft is becoming more and more urgent. Using the docking mechanism, large-scale space facilities can be assembled in space and complex space operations can be performed. The docking mechanism can establish mechanical, electrical and other functional connections between spacecraft, has the functions of repeatedly capturing, connecting and separating, and can meet the requirements of strength, stiffness and sealing after connection. [0003] During space rendezvous and docking, in the early capture process, hard impact capture is usually used,...

AI Technical Summary

Problems solved by technology

[0003] During space rendezvous and docking, in the early capture process, hard impact capture is usually used, supplemented by a spring damping mechanism to reduce the impact of the impact, the system is more complicated, and the effect is not ideal

[0004] In addition, the signal feedback device needs to be arranged in the active part of the docking mechanism, which puts forward higher requirements for the design of the locking signal feedback device of the active part, especially when the docking device of the active part is a rod type, due to the limited layout space, the signal Feedback device design is extremely difficult

The existing signal feedback devices usually use signal feedback devices such as contact switches, in-position switches, and proximity switches. These signal feedback devices are prone to misjudgment in the rod-type docking and supplementary integration device.
