The invention discloses a passive on-rail docking device for a space antenna module, comprising: a docking female head, a docking male head, a sliding bolt, a wedge-shaped limit ring, a pressing slider, a pressing push rod, and a pressing connecting rod , Cylindrical pins, limit springs, pretension springs and preload springs. Wherein the compression slide block, the compression push rod, the compression connecting rod, and the cylindrical pin form a locking mechanism. The passive on-orbit docking device of the space antenna module provided by the present invention can realize the on-orbit docking of the space antenna module. The passive on-orbit docking device of the space antenna module uses a pre-compressed spring to drive the sliding pin into the docking female head. And utilize and pre-stretch spring and locking mechanism, realize the locking of sliding bolt through the way of internal triggering. The invention does not need electric drive equipment and control equipment, has simple design, low manufacturing cost and high reliability.
Description
technical field [0001] The invention relates to the technical field of on-orbit docking of space antenna modules, in particular to a passive on-orbit docking device of a space antenna module. Background technique [0002] With the development of science and technology, space exploration, observation and space communication require super-large space antennas with larger apertures and higher surface accuracy. Since the structural size of the spacecraft is limited by the launch cost and launch envelope of the launch vehicle, a super-large space antenna system can be realized by assembling multiple space antenna modules on-orbit. Therefore, a simple and reliable on-orbit docking device for antenna modules is the key Fundamentals of space antennas. [0003] At present, there are many kinds of on-orbit docking devices for spacecraft, which can be divided into screw type, clamping type, pressure rod type and claw type, etc., but most of the spacecraft on-orbit docking devices are ...
