Abstract

The invention relates to a load assembly mechanism and a space load unfolding and retracting device. The load assembly mechanism includes a load body and an unfolding platform. One side of the unfolding platform is provided with a first stepped structure, and a guide column is arranged on the horizontal stepped surface of the first stepped structure. , one end of the unfolding platform is provided with a limit wall, the limit wall is provided with a captive screw, and the limit wall is provided with an elastic limit piece; the bottom side of the load body is provided with a second ladder adapted to the first ladder structure structure, the horizontal step surface of the second ladder structure is provided with a guide hole adapted to the guide column, and the end surface of the bottom end of the load body is provided with a limit groove and a screw hole adapted to the elastic limiter. The assembly of the load body and the unfolding platform is stable and reliable. The guide column is used for guidance and positioning, and the elastic limiter is used to limit the position. Finally, the captive screw is used for locking and positioning. The disassembly and installation of the load body are convenient and reliable. The need for long-term scalability and replaceable payloads.

Description

technical field [0001] The invention relates to the related technical field of space load assembly, in particular to a space load assembly mechanism and a space load unfolding and retracting device. Background technique [0002] With the development of space science and space technology and the continuous exploration of space by human beings, more and more space experiments need to be carried out. Especially with the completion of the space station and the explosive growth of the number of satellite launches, the types of space motion devices that space science experiment loads need to rely on are developing in the direction of diversification, basicity, long life, and scalability. Space launch missions have the characteristics of shortage of launch volume, launch weight, power supply, and communication resources. The space environment has environmental characteristics such as high and low temperature alternating, high vacuum, strong radiation, and space debris impact. The ...
