Abstract

The invention discloses a low-impact space docking electromagnetic sealing device, which includes a pole shoe assembly, a magnetic isolation ring, a permanent magnet, and a magnetic fluid arranged at the first aircraft docking port, and a bellows and base assembly provided at the second aircraft docking port. Seat, telescopic part, magnetic shaft. The pole shoe assembly includes at least two pole shoes, and a plurality of pole teeth are arranged on the pole shoes. A permanent magnet is arranged between two adjacent pole pieces. A magnetic isolation ring is provided on the side of the pole shoe assembly away from the second aircraft docking port, and the inner circular surface of the permanent magnet cooperates with the adjacent side surfaces of the two adjacent pole shoes to form an accommodation space. The base is connected to the inner circular surface of the shell of the second aircraft docking port, the telescopic part is fixedly connected to the base, and its output end is connected to the magnetic shaft. The base, the telescopic part and the magnetic shaft are all hollow inside and cooperate to form a cavity with openings at both ends. The bellows is located in the cavity, and the first end extends out of the cavity to connect with the side of the base away from the magnetic shaft. The two ends are connected with the inner wall surface of the magnetic conduction shaft.

Description

technical field [0001] The invention belongs to the field of spacecraft space docking, in particular to a low-impact space docking electromagnetic sealing device. Background technique [0002] The docking mechanism technology refers to the technology that can form a structure of two aircrafts through the process of contact, buffer, capture and rigid connection in space. Among them, the aircraft waiting for docking on the orbit is called the target aircraft, and the aircraft that docks with the target aircraft through a series of orbit changes and other motion controls is called the active aircraft. All aerospace powers, including my country, are developing a new generation of spacecraft space docking systems with typical technical features such as low impact, high reliability, standardization, versatility, light weight, high efficiency, and intelligence. Flexible docking, the impact load during the docking contact process is small, and the structure of the new-generation spa...
