Abstract

The invention discloses a deployable mechanism for a triangular prism unit modular plane antenna. The existing deployable mechanism units are complicated to assemble or difficult to fit on the work plane. The driving module at the central position of the present invention is arranged with N driving modules evenly distributed along the circumferential direction; the driving module includes a central connecting block, a spring, a driving slider, a supporting circular tube, a driving link, a joint link and a cylindrical pin; each phase Two adjacent peripheral drive modules are connected by two spaced chords, and each peripheral drive module is fixedly connected to the central drive module by two spaced unwinding chords. The invention can realize the two-dimensional plane folding of the large-scale antenna, the folding ratio is large, and the rigidity is high in the unfolded state; the triangular prism can be used to unfold the mechanism unit, and the fitting of the working plane is accurate.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a frame-type plane antenna deployable mechanism, in particular to a triangular prism unit modular plane antenna deployment mechanism. Background technique [0002] Compared with the rigid reflector antenna or the gas-filled reflector antenna, the frame antenna is a new type of deployable antenna. In the folded state, the volume of the antenna can be effectively reduced, and the carrying capacity of the rocket can be improved; when it reaches a predetermined orbit and is unfolded, it can provide better structural rigidity for the antenna. The frame-type antenna utilizes the idea of ​​modular expansion, and uses the modular unit mechanism to form the antenna support structure. By changing the number and size of the modular units, the expandable antenna support structure of different diameters can be obtained, so it is also called the modular antenna. . At present, tetrahedron or...
