Space shelf capable of being folded and unfolded

Abstract

The invention relates to a space shelf, in particular to the space shelf capable of being folded and unfolded. The lower side of an upper back board is hinged with the upper side of a lower back board; one side of a top beam is hinged with the upper side of the upper back board; the other side of the top beam is rotatably connected with one side of an upper longitudinal beam; one side of a bottombeam is hinged with the lower side of the lower back board; the other side of the bottom beam is rotatably connected with one side of a bottom longitudinal beam; the two ends of one side of the bottomlongitudinal beam are hinged with middle longitudinal beams; the two ends of the lower side of the lower back board are separately hinged with back board bottom longitudinal beams; and one surface, which faces towards each beam and each longitudinal beam, of the upper back board is equipped with a back board insertion pin assembly for realizing relative-angle fixing between the upper back board and the lower back board. The space shelf has the characteristics of being novel in structure, easy to implement a folding process and an unfolding process, being easy to store in a folding state, relatively high in stability after being unfolded, and the like, and is suitable for an occasion with relatively high requirements on storage and a folding-unfolding ratio in the aerospace field.

Description

technical field [0001] The invention relates to a space shelf, in particular to a foldable and unfoldable space shelf. Background technique [0002] In recent years, in order to meet various civil, military and scientific research needs, the space deployable mechanism has gradually become a research hotspot in various countries due to its advantages of small mass, foldability, low production cost and better transportation economy. The space expandable shelf is in a folded state before the loading or launch process, and can be unfolded from a smaller volume folded state and locked by a locking mechanism during work, thereby obtaining a larger working space, and has a wide range of application prospects in the aerospace field . [0003] Most of the existing space shelves are integral rigid structures, which cannot be folded and stored. They need to occupy a large space during transportation and in non-working states such as idle, which is not convenient for storage and transp...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing space shelves are integral rigid structures, which cannot be folded and stored. They need to occupy a large space during transportation and in non-working states such as idle, which is not convenient for storage and transportation.

In addition, the integral rigid shelf is increasingly difficult to meet the needs of the future development of deep space exploration due to its defects such as large mass, high production cost and high launch cost.
