Problems solved by technology

Since the height of the surrounding truss unfolded structure in the folded state is the sum of the two sides of the parallelogram, the folded volume is relatively large; at the same time, since the unfolding of the ring truss is driven by a rope, the unfolding reliability is low, and in order to drive th

Abstract

The invention discloses a tension integral deployable antenna, which mainly solves the problems of large folded volume and low deployment reliability in the prior art. It consists of n quadrilateral planar expansion units connected to each other through Hooke hinge joints (3) to form a regular polygonal prism-shaped expansion structure; each quadrilateral planar expansion unit adopts a spring frame structure, and the center adopts four support rods (2) and rotating The pair (4) is fixedly connected to form a cross-shaped retractable structure, and the two straight rods of the cross-expanded structure can rotate relatively around the central axis of the plane rotating pair; through the second spring (1-2) of each quadrilateral plane unfolding unit And the tension of the fourth spring (1-4) makes the overall structure unfold from the folded state. The invention has the characteristics of high deployment reliability and small folded volume, and is particularly suitable as a deployment structure for large spaceborne antennas, and can be used in the field of aerospace.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a tensioned integral expandable antenna, which realizes the automatic expansion of the antenna and can be used as a space reflector antenna. Background technique [0002] Spacecraft, especially satellite antennas, have become an indispensable part of any space system. Spacecraft antennas affect and restrict the performance and functions of the entire wireless communication system and even the entire spacecraft. Antenna technology has become an important part of promoting the technological progress and important factor in the development of space applications. [0003] In order to meet the needs of functions such as multi-function, multi-band, large capacity, high power, and long life, satellite antennas inevitably tend to be larger in diameter. Because space equipment equipped with antennas needs to be sent into space by rockets, satellite antennas must be made foldable, that i...
