Unfolding hinge for quick connection and separation

Abstract

The invention discloses an unfolding hinge for quick connection and separation. The unfolding hinge can unfold a solar wing box board within a certain angle range and achieve in-orbit quick connection and separation of a solar wing. The unfolding hinge comprises a male hinge assembly, a female hinge assembly and a connection and separation device. When the hinge is unfolded, drive force stored by a volute spiral spring when the hinge is in the folded state is transmitted to a female hinge from a male hinge through a shaft, and meanwhile, a flat head screw in the female hinge assembly and a round head screw in the male hinge assembly conduct limiting in the unfolding direction; and an impact load is reduced through a damper in the last period of unfolding. When the solar wing box board and a sleeve are located in the connection state, a locking pin shaft in the female hinge assembly is locked into a locking pin shaft locating hole in a connection and separation base through locking swing rods in the connection and separation device; in the separation state, locking pins on the locking swing rods are located at the locked ends of locating grooves of the locking swing rods; and the female hinge assembly is separated from the connection and separation device.

Description

technical field [0001] The invention relates to the technical field of solar wing box panel deployment and on-rail replacement, in particular to a deployment hinge for quick connection and separation. Background technique [0002] With the continuous increase of the types of spacecraft, the spacecraft has put forward new requirements for the configuration of the solar wing, the stiffness of the deployment, and the replacement in orbit. The traditional solar wing adopts lock hook type or pin type hinges for deployment and fixation, and its deployment angle is fixed. Since the flexible solar wing box panel used in the present invention has a large volume and many links in the size chain, the accumulation of errors is relatively large. The deployment hinge at the deployment angle cannot eliminate this error, which in turn causes the sunwing to be over-constrained. At the same time, this deployment hinge is fixedly connected to the solar wing and does not have the ability to be...

AI Technical Summary

Problems solved by technology

The traditional solar wing is unfolded and fixed by lock hook type or pin type hinge, and its deployment angle is fixed. Since the flexible solar wing box panel used in the present invention is large in volume and has many links in the size chain, the error accumulation is relatively large. Deployment hinges at deployment angles do not eliminate this error, resulting in overconstraint of the sunwing

At the same time, this deployment hinge is fixedly connected to the solar wing and does not have the ability to be replaced on orbit. Once the solar wing fails or reaches the end of its life, it cannot be replaced.
