Problems solved by technology

[0008] 3. The combination mechanism in the prior art is composed of expandable units, but due to the limited structure, the expandable units can only be composed of one type of expandable units, and cannot be composed of multiple types of expandable units, and the functions are relatively single and weakened
[0009] 4. A single deployable unit in the prior art is often composed of a single rod, and its structure and function are relatively single and weakened
[0010] 5. A single deployable unit in the prior art is often a straight rod, so the degree of freedom is limited
[0011] 6. In the single expandable unit of the prior art, the spatial relative positions of the unit rods are often scattered, resulting in insufficient space utilization and poor storage capacity

Description

technical field [0001] The invention relates to the field of expandable mechanisms, in particular to a cylindrical surface mechanism composed of expandable units. Background technique [0002] An expandable mechanism refers to a type of mechanism that can be unfolded from a collapsed state to a predetermined state. It is characterized by a large dimensional change capability in one or more specific directions. In recent years, deployable mechanisms have been widely used in aerospace engineering, civil engineering, medical, military and other fields. The expandable mechanism generally adopts a modular design, that is, several identical modules form a network through a special connection method, and each expandable module is called an expandable unit. [0003] According to the number of directions of size change, the expandable mechanism can be divided into one-dimensional expandable mechanism, two-dimensional planar expandable mechanism and three-dimensional solid expandabl...
