Foldable tent based on rigid folded paper

Abstract

A foldable tent based on rigid folded paper comprises a foldable arched shed roof, a left curtain, a right curtain and a bottom plate. The deployable arched shed roof is formed by longitudinally splicing and combining a plurality of folding layers, and each folding layer comprises two deployable units which are symmetrically distributed; each extensible unit comprises a first isosceles trapezoid panel, a second isosceles trapezoid panel, a first right trapezoid panel, a second right trapezoid panel, a third isosceles trapezoid panel, a fourth isosceles trapezoid panel, a fifth isosceles trapezoid panel and a sixth isosceles trapezoid panel. The deployable arched shed roof is of an integrated structure, comprises hydrophobic cloth on the outer layer, a rigid panel on the middle layer and flame-retardant cloth on the inner layer, and is processed and manufactured through lamination forming. The deployable arched shed roof is completely unfolded into an arched semi-tube shape from a flat shape when being completely folded; the foldable tent does not need to be additionally covered with tarpaulin, after being unfolded, the foldable tent only needs to be fixed to the bottom plate, then the left curtain and the right curtain are installed, the foldable tent can be put into use, the building process is simple, and the speed is high.

Description

technical field [0001] The invention relates to the field of expandable mechanisms, in particular to a foldable tent based on rigid origami. Background technique [0002] Origami refers to the creative process of forming three-dimensional complex spatial structure shapes from simple two-dimensional paper according to set creases. It was first known as an art form. In recent years, with the development of mathematics and natural sciences, origami technology has gradually attracted the attention of many engineering fields, providing countless design inspirations for engineering technical problems. Rigid origami means that during the paper folding process, the panels between the creases cannot be stretched or torsionally deformed. At this time, each panel is in a rigid state and can only rotate around the creases. Due to the large folding-to-expansion ratio and low price of rigid origami technology, its development potential has been explored in more and more fields, mainly in...

AI Technical Summary

Problems solved by technology

[0004] 1. The foldable tents in the prior art are often composed of multiple parts such as an expandable frame, columns, door curtains, and tarpaulins covering the frame. The construction process is cumbersome and slow

[0005] 2. The expandable mechanism in the collapsible tent of the prior art is often obtained by hinged at both ends of the rod, which makes the overall rigidity of the expandable mechanism poor. If the rigidity is increased by increasing the size of the rod and the hinge, a part will be lost The folding ratio and portability limit the practicability of the mechanism

[0006] 2. The expandable mechanism in the foldable tent of the prior art often has multiple degrees of freedom, requires the cooperation of multiple people, and the unfolding and folding process is cumbersome

[0007] 3. The expandable mechanism in the expandable tent of the prior art is often obtained by connecting more rods. Although it can achieve a larger folding-expanding ratio, it is prone to misfolding

[0008] 4. When the expandable mechanism in the foldable tent of the prior art is stored, the rods are often scattered, resulting in insufficient space utilization and poor storage
