Problems solved by technology

[0004] It can be seen from the above that the current research on the expandable mechanism mainly focuses on the kinematics and dynamics of the mechanism, but there are not many designs on the design of the expandable mechanism itself, especially the unit design of the flat-plate folding mechanism.

Abstract

The invention discloses a flat plate folding and unfolding unit. The flat plate folding and unfolding unit comprises a folding and unfolding mechanism and a support mechanism side, wherein the supportmechanism side is above the folding and unfolding mechanism; the support mechanism side is connected with the folding and unfolding mechanism through a vertical support rod; components of the flat plate folding and unfolding unit are connected directly through revolute pairs, so that the structure is simple and reasonable; a folding and unfolding direction of the support mechanism side is fully vertical to the folding and unfolding direction of an antenna flat plate, so that the support rigidity is improved, and the unit unfolding structure is more stable. The invention further discloses a flat plate folding and unfolding antenna mechanism. The mechanism is formed by connecting the plurality of flat plate folding and unfolding units; the flat plate folding and unfolding units are totallyidentical and are symmetrical in structure; and the flat plate folding and unfolding units are directly connected without auxiliary pieces, thereby being convenient to manufacture and assemble, expanding strongly, being capable of making up large flat plate folding and unfolding antenna mechanisms in any length contracting highly according to needs, and being highly practical.

Description

technical field [0001] The invention belongs to the technical field of aerospace vehicles, and in particular relates to a flat-panel folding unit and a flat-panel folding antenna mechanism. Background technique [0002] With the in-depth exploration of the mysteries of the universe, aerospace technologies such as super-large and high-precision satellites and space stations occupy an important position in various fields. The space unfolding structure is generally in the folded state on the ground and during the launch process. When the spacecraft is positioned on the working orbit and is ready, the driving device will make it unfold into the preset working state. At present, various spacecrafts have widely used this folding structure. However, due to the limited storage capacity of ground-based space launchers, aerospace engineering is more and more urgent for the further development of various space foldable structures. [0003] The research on plane folding mechanism has ...
