Description
Technical Field
The invention relates to the application field of expandable mechanisms, in particular to a foldable cylindrical shelter.
Background
An expandable mechanism refers to a type of mechanism that is capable of expanding from a collapsed state to a predetermined state. It features large size variation in specific direction or directions. In recent years, deployable mechanisms have been widely used in the fields of aerospace engineering, civil engineering, medical treatment, military and the like. The expandable mechanism is generally designed in a modular manner, that is, a plurality of identical modules form a network through a special connection method, and each expandable module is called an expandable unit.
The developable mechanism can be divided into a one-dimensional developable mechanism, a two-dimensional planar developable mechanism and a three-dimensional body-shaped developable mechanism according to the number of the size change directions. Two-dimensional cylindrical developable mechanisms are common and are widely applied to the fields of temporary medical square cabins, space antenna support frames and the like. At present, experts at home and abroad successfully develop various types of expandable mechanisms by taking spatial mechanisms such as four-bar mechanisms, six-bar mechanisms, seven-bar mechanisms and the like as expandable units. However, the existing deployable units are of fewer types, and the connections between the units are mostly more complicated.

2. The single deployable unit of the prior art is often composed of a single type of rod, which is relatively unitary and weakened in structure and function.
3. The individual deployable units of the prior art tend to be linear rods and thus have limited degrees of freedom.
