Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with specific implementation examples. In this embodiment, in order to better illustrate the connection relationship between the central regular hexagonal frame and the surrounding regular hexagonal racks, the first group of connecting rods, the second group of connecting rods, the third group of connecting rods and the fourth group of connecting rods are used here. Each group of connecting rods is composed of two connecting rods. One end of the first group of connecting rods has no boss and the other end has a boss; the other two connecting rods in each group of connecting rods have two Bosses are provided at all ends; and in all connecting rods, the heights of the bosses are not the same.

[0026] as attached Figure 1-6 As shown, the regular hexagonal expansion mechanism is composed of seven regular hexagonal racks and 24 ordinary double hinge point linear connecting rods...

Abstract

The present invention is a regular hexagonal planar unfolding mechanism, which is formed by connecting seven regular hexagonal frames and 24 ordinary double-hinge point linear connecting rods through cylindrical pins; one of the regular hexagonal frames is the frame At the central part, the remaining six regular hexagonal racks surround the central regular hexagonal rack, and the seven regular hexagonal racks are sequentially connected to each other in a certain way. Wherein, an ordinary double-hinge-point linear connecting rod can be used as a driving rod to rotate around the hinge point connected to the regular hexagonal frame. The principle is simple, the reliability is high, the component types are few, the size is single, the repeatability is strong, the processing is simple, easy to assemble, the error is small, the unfolding process is stable, the impact is small, the whole system has only one degree of freedom, and the mechanism is driven by a micro motor. Simple to drive and easy to control.

Description

technical field [0001] The invention belongs to the field of structural design, and relates to a plane expansion and contraction mechanism, in particular to a plane expansion mechanism based on a regular hexagon. Background technique [0002] With the development of space technology and information technology, expandable mechanisms have gradually come into people's field of vision, and their application fields are also very extensive. For example, space-borne extendable antennas and solar cell wings on various satellites, their application is due to the limitation of the effective carrying space and carrying capacity of the rocket, and they are required to be fixed in the payload compartment of the vehicle in a folded shape during the launch stage, waiting for spaceflight. After the device enters the orbit, the ground control center instructs it to gradually complete the unfolding action in the space orbit according to the design requirements, and after locking, it will rema...
