Abstract

The invention relates to a load assembling mechanism and a spatial load unfolding and folding device.The load assembling mechanism comprises a load body and an unfolding platform, a first step structure is arranged on one side of the unfolding platform, a guide column is arranged on the horizontal step surface of the first step structure, a limiting wall is arranged at one end of the unfolding platform, and a captive screw is arranged on the limiting wall; an elastic limiting piece is arranged on the limiting wall; and a second step structure matched with the first step structure is arranged on one side of the bottom of the load body, a guide hole matched with the guide column is formed in the horizontal step surface of the second step structure, and a limiting groove matched with the elastic limiting piece and a screw hole are formed in the end surface of one end of the bottom of the load body. The load body and the unfolding platform are stably and reliably assembled, the guide columns are used for guiding and positioning, the elastic limiting pieces are used for limiting, finally the captive screw is used for locking and positioning, the load body is convenient and reliable to disassemble and assemble, on-orbit replacement is convenient, and the requirements of long-term extensible and replaceable loads can be met.

Description

technical field [0001] The invention relates to the related technical field of space load assembly, in particular to a 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 type a...
