Telescopic space boom mechanism for supporting detection load

Abstract

The invention provides a telescopic space boom mechanism for supporting a detection load. The telescopic space boom mechanism is mainly composed of a storage part, a transmission part and a support part, wherein the storage part is used for storing a curled boom; the transmission part is used for transmitting a moment; a motor is used for providing an active moment to drive an active guide wheel to turn so as to guide the boom to expand; and the support part is used for keeping the relative position of each part of a boom system. The three parts, namely the storage part, the transmission part and the support part, work cooperatively to form the whole system. The telescopic space boom mechanism for supporting the detection load has the advantages that the weight of the whole system is reduced due to large magnification ratio of the boom mechanism; a torsion spring at the storage part ensures that the boom can be taken back successfully; the boom can be expanded stably and influence of the boom on posture of a satellite body is reduced; the motor the location of which can be controlled ensures the precision of expansion position. The telescopic space boom mechanism disclosed by the invention can be applied to expansion of detection loads of small satellites; and compared with the traditional boom mechanism, the telescopic space boom mechanism disclosed by the invention has the advantages of large magnification ratio, capability of being taken back, stable expansion, position controllability and the like.

Description

technical field [0001] The invention relates to the technical field of space detection, and relates to a telescopic space extension rod mechanism for supporting detection loads, which is suitable for supporting small satellite detection loads. Background technique [0002] The space deployment mechanism is one of the main mechanisms to realize the functions of solar sails, antenna deployment, and detection load support. With the deepening of research, this technology has become more mature, and many different space deployment mechanisms have emerged. It is mainly divided into truss type expansion mechanism, inflatable type expansion mechanism and telescopic expansion mechanism. [0003] The truss-type deployment mechanism uses hinges to connect rods to form a grid-like deployment structure. Its advantages are good mechanism performance and large length, but its disadvantages are bulky and complex structure. Mainly used in space probes, larger solar panels and gravity gradi...

AI Technical Summary

Problems solved by technology

[0008] The above two types of telescopic space deployment mechanisms have shortcomings. The sleeve telescopic deployment mechanism is relatively bulky and limited in length, and the thin-walled tube telescopic deployment mechanism is uncontrollable and cannot be retracted during the deployment process, and cannot fully adapt to small satellites.
