Unfolding hinge and satellite-borne antenna

Abstract

The invention relates to the technical field of hinge equipment, and provides an unfolding hinge and a spaceborne antenna. According to the unfolding hinge, a mother hinge is provided with a slide way, and the mother hinge is used for being connected with a first plate of the spaceborne antenna; the male hinge and the female hinge are hinged through a first hinge shaft, the male hinge is provided with a locking assembly, the locking assembly is clamped with the slide way when the male hinge and the female hinge are located on the same plane, the male hinge is provided with a limiting groove, the male hinge is used for being connected with a second plate of the spaceborne antenna, and the limiting groove is used for limiting the second plate of the spaceborne antenna when the spaceborne antenna is in a folded state. A limiting effect is formed on a third plate of the satellite-borne antenna; the inner ring of the first elastic piece is connected with the first hinge shaft, the end of the first elastic piece is connected with the male hinge, and the first elastic piece is used for driving the male hinge to rotate. According to the unfolding hinge, by arranging the female hinge, the male hinge and the first elastic piece, after the pressing force is relieved, the panel of the spaceborne antenna can be automatically driven to be unfolded in sequence, and the unfolding requirement of the panel of the spaceborne antenna is met.

Description

technical field [0001] The present invention relates to the technical field of hinge equipment, in particular to an unfolding hinge and a spaceborne antenna. Background technique [0002] Due to the limitation of the effective launch volume of the space vehicle, the spaceborne antenna or solar wing needs to be folded up when launching. After entering the orbit, the deployment hinge drives the antenna or solar wing to expand, lock and enter the working state. The spaceborne antenna or solar wing is usually composed of multiple panels, and the deployment of different panels needs to be in a certain order to avoid interference and collision between different panels and ensure the normal operation of the spaceborne antenna or solar wing. However, the traditional hinge can only realize the unfolding and locking of the antenna or the solar panel, and cannot control the unfolding sequence of different panels by itself. SUMMARY OF THE INVENTION [0003] The present invention prov...
