Problems solved by technology

[0004] In the existing unfolding mechanism, the process of realizing folding to unfolding is usually realized by axial movement, such as an umbrella or a hydraulic rod, which takes up a large axial space
There are also radial deployments that are usually achieved by inflation, but obviously, axial movement or inflatable radial deployments take up a relatively large space, and the rigidity after deployment is insufficient

Abstract

The invention discloses a radial unfolding mechanism, which comprises a plurality of ring bodies and a plurality of unfolding parts, wherein the ring bodies are arranged in parallel; the unfolding parts are arranged on outer sides of the ring bodies and can be unfolded in a radial direction; the plurality of ring bodies include a fixed ring body and at least one rotating ring body; each fixed ring is internally provided with a driving part used for driving the rotating ring body to rotate; a transmission part connected with the driving part is arranged in the rotating ring body; each unfolding part comprises a first bracket and a second bracket which are connected to different ring bodies respectively; and the bottom span of the first bracket and the bottom span of the second bracket are changed through rotation of the rotating ring body. The radial unfolding mechanism disclosed by the invention is simple in structure, reasonable in design, convenient to implement, capable of being effectively applied to radial expansion, capable of achieving a large radial expansion distance with a small axial space, good in rigidity after being expanded, good in using effect and convenient to use and popularize.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a radial expansion mechanism. Background technique [0002] With the development of society, various types of machinery continue to pour into people's lives. In order to meet various working conditions, various mechanical structures have been invented by people, and in order to reduce or increase the size of mechanical structures under non-working conditions The movement form of the mechanical structure and various unfolding mechanisms have been designed by people. [0003] Compared with the rigid structure, the overall size of the folded structure, which is the same size when unfolded, will be reduced several times after being folded, making it require less space for storage and transportation, and has a higher degree of freedom during movement, making The forms of movement during its work are more varied. [0004] In the existing unfolding mechanism, the...
