Problems solved by technology

In terms of the driving mechanism, the deployment process of the motor-driven mechanism is controllable and can be fine-tuned after deployment, but this kind of mechanism is complicated and requires an additional mechanism to assist locking, which increases the quality of the entire mechanism, is difficult to control, and is susceptible to external interference

Abstract

The invention discloses a parabolic cylinder antenna deployable mechanism with multiple hyperelastic hinges. The parabolic cylinder antenna deployable mechanismantenna comprises a triangular prism extension arm, a transverse rib mechanism, a synchronous hinge and a parabolic cylinder antenna., wherein tThe triangular prism extension arm is composed of a triangular rod, a longitudinal rod, a hyperelastic hinge, a longitudinal rod joint and a rope, the transverse rib is composed of a straight rod and a hyperelastic hinge, the synchronous hinge is composed of a synchronous gear, a connecting rodjoint and a support frame, and the parabolic cylinder antenna is a metal mesh surface film antenna. According to the parabolic cylinder antenna deployable mechanism with the multiple hyperelastic hinges, the mass of the whole mechanism is reduced, self-locking can be achieved after the mechanism is completely unfolded, the phenomena of friction and jamming in the unfolding process are reduced, andtherefore thus the whole mechanism is simple in structure and large in unfolding and folding ratio; the synchronism of unfolding of the transverse ribs is ensured by the synchronizing mechanism; theexpansibility of the triangular prism extension arms and the transverse ribs is high, so that the deployable mechanism can obtain an the antenna of a hundred-meter level or a larger scale by controlling the number of the modules.

Description

technical field [0001] The invention relates to the technical field of aerospace thin film antennas, in particular to a deployable mechanism for a parabolic cylindrical antenna with multiple superelastic hinges. Background technique [0002] At the beginning of the spacecraft launch, the thin film antenna is tightly wound and stored in the load compartment. When working, the antenna needs to have a large working surface, which has provided sufficient signal transmission and reception functions. The space deployable mechanism is an important factor to realize this series of actions and functions. Assure. [0003] In the field of deployable mechanisms in the aerospace industry, the antenna deployment mechanisms mainly include solid reflective surface, skeleton, mesh and film antennas. The metal mesh antenna type only uses a small number of rods as support rods, and the reflective surfaces are all made of flexible materials. It is light in weight and simple in structure, so th...
