AI Technical Summary

Technical Problem

The traditional scissors and fork-type expansion mechanism makes the overall structure of the solar wing complex and large in size, making it difficult to meet the space needs of small spacecraft.

Method used

A deployment mechanism including a carrier, a rotating shaft and a guide portion is adopted. The curling arm is wound through the rotating shaft. The guide portion provides a limit to avoid excessive displacement. The speed control member controls the rotation speed and the locking assembly fixes the curling arm.

Benefits of technology

The overall structure of the solar wing is simplified, the volume is reduced, making it suitable for the space needs of small spacecraft, and the design of guide parts and speed control parts ensures the stable expansion and closing of the curling arms.

Abstract

The invention belongs to the technical field of aerospace equipment, and discloses an unfolding mechanism and a spacecraft, and the unfolding mechanism is used for winding and unwinding a curling arm and comprises a bearing part, a rotating shaft and a plurality of guide parts. The rotating shaft is rotationally arranged on the bearing piece, one end of the curling arm is fixed to the rotating shaft, and the rotating shaft is used for winding and unwinding the curling arm. The multiple guiding parts are distributed on the bearing piece along the periphery of the rotating shaft and used for providing guiding in the winding and unwinding process of the winding arm. The curling arm is wound through the rotating shaft, and the curling arm can be unfolded or folded by rotating the rotating shaft, so that the solar wing adopting the unfolding mechanism is simple in overall structure, small in size and capable of meeting the space requirement of a small spacecraft. Comprising the unfolding mechanism is small in size and can meet the requirement of miniaturization design.
