Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] A space inflatable structure that can be reversely expanded and shaped and covered according to the present invention includes: a covering cover body 1, a directional unfolding flip structure (2, 3), and a directional expanding locking mechanism 4; out, and reversely unfolded to cover the entire cone; the cover body 1 is divided into 4 fan-shaped surfaces, and the zipper rails are sewn on the straight edges of the fan-shaped surfaces. The free end of the zipper rail is located in the direction of the top of the fan-shaped surface, that is, after unfolding, the starting point of the zipper rail, that is, the constraint end, is located in the direction of the bottom of the cone, the end point of the zipper rail, that is, the free end is located in the direction of the top of the cone, and the middle position of each cover body 1 is along the The di...

Abstract

The invention discloses a space inflatable structure capable of being unfolded and formed in the reverse direction and cladding, and provides a space inflatable structure capable of being unfolded and formed in the reverse direction and cladding an inverted cone structure. The space inflatable structure comprises a cladding cover body (1), a directional unfolding overturning structure (2, 3) and a directional stretching locking mechanism (4); the cladding cover body (1) is divided into multiple pieces of fans uniformly; mutually-matched zipper tracks are sewed on the line edges of the fan-shaped surfaces; the directional unfolding overturning structure (2, 3) comprises combined rings (3) and tubular inflatable truss structures (2) of which the number is the same to that of the fan-shaped surfaces; the directional unfolding overturning structure (2, 3) forms a U-shaped structure in the generatrix direction of the cone as a whole, and thus the fan-shaped surfaces of the cladding cover body (1) forms a cladding structure. The directional stretching locking mechanism (4) of a tubular structure which is stretched after being inflated, and a zipper head structure is arranged at the top of the directional stretching locking mechanism (4). Compared with the space structure in the traditional form, the space inflatable structure has the advantages of low cost, small volume, light weight and the like.

Description

technical field [0001] The invention relates to a space inflatable structure, in particular to a space inflatable structure with the functions of reversely unfolding and forming and wrapping an inverted cone structure. Background technique [0002] At present, the application research of space inflatable unfolding structures mainly includes large-scale unfolding antennas, telescopes, solar panels, and planetary habitats. These inflatable structures unfold forward and around in free space and form a predetermined shape, and cannot be reversely unfolded after forming. Coating of the surface of the carrier. Contents of the invention [0003] The technical solution of the present invention is to provide a space inflatable structure design method that can realize reverse unfolding and forming and wrapping an inverted cone structure, and use the theory of minimum stress stability of the inflatable membrane structure and the self-guided stretching structure to realize its space r...
