Intelligent unfolding and folding module adopting multi-unit series-parallel connection control

Abstract

The invention discloses an intelligent unfolding and folding module adopting multi-unit series-parallel connection control. The intelligent unfolding and folding module comprises multiple connection rod mechanisms. The multiple connection rod mechanisms are connected with one another through connection units. The middles of two movable connection side faces of each connection unit are each provided with a linear groove. A hemispheric groove is formed in the center of each linear groove. The diameter of each hemispheric groove is greater than the width of the corresponding linear groove. The tail end of each connection rod body is fixedly connected with a fixed connection side face of one of the corresponding connection units, and the head end of each connection rod body is connected with a movable connection side face of the other connection unit in a rotary manner. A spherical-surface protrusion at the head end of each connection rod body is matched with the corresponding hemispheric groove in the movable connection side face of the corresponding the other connection unit, so that a spherical-surface pair is formed. Each spherical-surface protrusion is tightly clamped into the corresponding hemispheric groove through pressing pieces from the two sides of the corresponding linear groove. Each connection rod body is further provided with an actuating mechanism. Each actuating mechanism drives the corresponding spherical-surface pair to rotate. The intelligent unfolding and folding module has the beneficial effects that multi-freedom-degree position and posture change can be achieved, and requirements of different tasks are met.

Description

technical field [0001] The invention relates to a retractable module used in aerospace and other fields, in particular to a retractable module with intelligent multi-unit series-parallel control. Background technique [0002] In a space environment full of magnetic radiation, temperature gradients, and a large amount of space debris, the spacecraft must perform continuous adjustment of multiple degrees of freedom on-orbit, while the existing retractable mechanism can only perform two degrees of freedom in a fully deployed or retracted state. Rigidity adjustment, so the flexible retractable space mechanism and its mechanism of action have become the key issues to be solved urgently in the research of existing spacecraft. In terms of aviation navigation, most of the existing fixed-wing aircraft have single aerodynamic characteristics and can only achieve optimal flight efficiency under certain flight conditions. Different missions often have conflicting requirements on aircra...
