Abstract

The invention discloses a point type microsatellite separation unlocking device. The point type microsatellite separation unlocking device comprises a swinging rod device and an electromagnet device; the swinging rod device comprises a first swinging rod, a bracket, a tension spring, two bearings and two pin shafts; the bracket is fixed on an adapter; the first swinging rod is a 7-shaped rod; a first through hole the middle part of the first swinging rod; a second through hole is formed in the top end of the first winging rod in a staggered manner; the first through hole is rotationally connected with the bracket through the pin shaft; the pin shaft is arranged in the second through hole; bearings are arranged at the two ends of the pin shaft; the bearings are pressed on a satellite structure and can lock the Z direction of the satellite; a vertical plane is milled on the external wall of the lower end of the first swinging rod; one end of the tension spring is fixed on the vertical plane; and the other end of the tension spring is connected to the adapter. The point type microsatellite separation unlocking device has the advantages of simple structure, reliable operation, small impact, repeatability and low cost.

Description

technical field [0001] The invention relates to a separation and unlocking device for a satellite and a carrier rocket, in particular to a point-type micro-satellite separation and unlocking device. Background technique [0002] Since the 1980s, with the rapid development of technologies such as microelectronics, micromechanics, precision machining, light materials, and high-efficiency energy, the miniaturization of instruments and equipment required on satellites has been promoted. Shorter, lower cost, smaller size, and more flexible", the upsurge of micro-satellite development is rapidly rising around the world. As one of the key technologies of satellites, unlocking and separation technology is the core technology related to the successful launch and normal orbiting of satellites, and has an important impact on the overall performance of satellites. Therefore, it is of great significance to invent an unlocking and separating device with little separation impact and high ...
