Abstract

The invention belongs to the technical field of devices combining antenna components with antennas, and discloses a novel double-layer scissor parabolic cylindrical expandable truss antenna device, which is composed of a plurality of double-layer scissor hinge mechanisms, wherein adjacent double-layer scissor hinge mechanisms are connected to each other by a double-headed hinge, a sliding hinge, athree-headed hinge and a four-headed hinge to form a closed parabolic cylinder; each double-layer scissor hinge mechanism consists of two vertical rods, two long inclined rods, two short inclined rods, four double-headed hinges, four sliding hinges, and two springs; and adjacent two double-layer scissor hinges share a vertical rod, a double-headed hinge or a three-headed hinge or a four-headed hinge, a sliding hinge, and a spring. The invention has high geometric stability, strong rigidity, simple movement mechanism and control system, small volume after closing, high storage rate, strong module expansion, as well as simple assembly, and may be respectively deployed in the axial or length direction, thereby satisfying the requirements for the use of aperture antennas.

Description

technical field [0001] The invention belongs to the technical field of antenna components or devices combined with antennas, and in particular relates to a novel double-layer scissor-type parabolic cylinder expandable truss antenna device. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the rapid development and deepening of space science and technology, aerospace engineering, and various space exploration activities, the demand for high geometric stability, large scale, and light weight of space structures has become more and more urgent. However, due to the limited carrying space of aerospace vehicles, it is impossible to directly send the formed large-scale space structure into orbit. Therefore, it is necessary to design a space-deployable antenna device with a large folding-to-expansion ratio. During the ground launch phase, the deployable antenna device is in a folded state. It is fixed in the paylo...
