Problems solved by technology

Obviously, when the reflector is expanded to a certain caliber, the distance between the metal joint at the end of the tape and the reflector is the smallest after the tape is unlocked. When the distance is too small, the end joint of the tape will collide with the composite rod of the reflector, which may Damaged composite rods

Abstract

The invention discloses a satellite-borne antenna wrapping belt high-damping automatic rebound-stopping device. The satellite-borne antenna wrapping belt high-damping automatic rebound-stopping devicecomprises a root expansion joint, a composite material wrapping belt, two ratchet wheel devices, two root fixing clips, two composite material reinforced belts and at least two flexible connecting belts, wherein the ratchet wheel devices are connected with the root expansion joint through the root fixing clips; the composite material reinforced belts are fixed on the composite material wrapping belt through the root fixing clips and the adjacent flexible connecting belts; the at least two flexible connecting belts are uniformly wound on the composite material wrapping belt; the two ratchet wheel devices, the two root fixing clips and the two composite material reinforced belts are arranged symmetrically around the root expansion joint. By virtue of the satellite-borne antenna wrapping belt high-damping automatic rebound-stopping device, the rebound displacement after unfolding of the composite material wrapping belt is effectively lowered, the reliability and the safety in the antennaunlocking and unfolding are ensured.

Description

technical field [0001] The invention belongs to the technical field of space expandable structures, and in particular relates to a high-damping self-return device wrapped with a space-borne antenna. Background technique [0002] Reliable locking in the folded state and reliable deployment on orbit are the key characteristics of the deployable antenna, and its reliability determines the success or failure of the antenna deployment. In order to make the folded state of the large expandable antenna have sufficient rigidity and be able to bear the mechanical load during satellite launch, flexible straps are generally used to fasten the folded state of the antenna; During the unfolding process, it will unfold along with the antenna. [0003] For example, patent ZL201410299579.6 provides a typical flexible composite material carbon ribbon-type deployable reflector wrapping scheme in engineering applications: the wrapping mainly consists of two composite wrapping straps (carbon fi...
