Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown is a structural schematic diagram of a space multi-ring scissor unit openable roof with redundant constraints based on the idea of ​​the present invention, including scissor unit rings, roof panels, and the like. The scissor unit ring and the roof panel are connected by pins.

[0025] Among them, the scissor unit circle has a total of multiple circles (three circles and above), and the scissor unit 2 is formed by pinning two strip plates through the pin 3, forming a middle hinge node in the middle, and the scissor unit 2 is respectively in the The ends are pinned together by pins 3, and an annular scissor unit circle is formed after unfolding.

[0026] The roof panel is composed of a circle of folding units evenly distributed in the same space, and the folding units are also connected by pin joints. The two folding units at the beginning...

Abstract

The invention discloses an openable roof with a redundancy restraint function and spatial multi-ring shear type units. The openable roof is composed of shear type unit rings and a roof panel, the number of the shear type unit rings is at least three, each shear type unit ring is composed of a circle of shear type units, each shear type unit is composed of two strip-shaped plates which are in pin joint at a middle pin-joint node of the middle portions of the strip-shaped plates, and every two adjacent shear type units are in pin joint through pins at end portions of the strip-shaped plates. The roof panel is composed of fan-shaped plates of the same size, wherein every two adjacent fan-shaped plates are in pin joint at the side faces to form a folding unit, junction lines of every two adjacent fan-shaped plates in the spatial roof form a crest line and a valley line respectively, and the at least three shear type unit rings are arranged on the crest lines and the valley lines at intervals, and are located at positions with different radius with the circle center of the roof panel. The roof structure is unfolded and folded through the shear type unit rings, and annular opening and closing of the roof are achieved; meanwhile, due to the redundancy restraint function, roof reliability is guaranteed.

Description

technical field [0001] The invention relates to an openable roof structure, in particular to a space multi-ring scissor unit openable roof structure with redundant constraints. Background technique [0002] The deployable structure is a new type of structure developed in the past half a century, and it plays an important role in the fields of aerospace, building structure and military engineering. The main feature of a deployable structure is that it has two stable configurations: a fully folded state and a fully unfolded working state. In the folded state, the structure is gathered in a certain shape, and under the action of external driving force, the structure is gradually unfolded, reaching the fully unfolded working state, and then locked into a stable state. [0003] The deployable scissor hinge structure is a space structure based on the scissor hinge unit, which can design a variety of geometric shapes. This structure becomes a tight bundle after being fully folded...
