A Repeatable Folding Mechanism and Satellite Solar Wing

Abstract

The invention relates to the technical field of aerospace equipment, in particular to a repeatable folding mechanism and satellite solar wings. The repeatable folding mechanism comprises a left solarwing, a right solar wing, folding and expanding working pair and locking and unlocking working pair; the driving shaft of the folding and expanding working pair is connected with the left solar wing,the driven shaft of the folding and expanding working pair is fixedly connected with the right solar pair, the driving shaft and the driven shaft are in transmission connecting with each other so thatthe left solar wing can be expanded or folded under the action of the driving shaft, and the right solar can be expanded or folded under the action of a driven wheel; the locking and unlocking working pair is connected with the folding and expanding working pair and used for the locking and unlocking of the folding and expanding working pair. The mechanism and the solar wings have the advantagesof being small in size and reliable to lock, by means of groove wheels and cam mechanisms, repeated expanding and folding and locking and unlocking of the solar wings can be completed to meet demandsof maneuvering orbital transfer of a satellite and eliminate the influence of the solar wings on the satellite in the maneuvering orbital transfer process of the satellite.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a repeatable folding mechanism and a satellite solar wing. Background technique [0002] At present, the solar wing provides energy for the satellite, and it is usually in a folded state when the rocket carries the satellite for launch. After the satellite is separated from the rocket, it is unfolded by the unfolding mechanism. [0003] Most of the existing solar wing deployment mechanisms are one-time deployment mechanisms. The solar wing is locked by a locking mechanism during launch and is in a folded state. After the star and arrow are separated, the locking mechanism is unlocked, and the deployment mechanism uses its own spring or memory material. The compression can provide the deployment force, complete the deployment action and lock. With the development of satellite technology, the area of ​​the solar wing increases, and the demand for satellite maneuvering i...

Problems solved by technology

[0003] Most of the existing solar wing deployment mechanisms are one-time deployment mechanisms. The solar wing is locked by a locking mechanism during launch and is in a folded state. After the star and arrow are separated, the locking mechanism is unlocked, and the deployment mechanism uses its own spring or memory material. The compression can provide the deployment force, complete the deployment action and lock. With the development of satellite technology, the area of ​​the solar wing increases, and the demand for satellite maneuvering increases. The one-time deployment mechanism cannot retract the solar wing again. It is easy to break. At the same time, the vibration of the solar wing will also affect the attitude of the satellite, which may cause damage to the function and performance of the satellite. The one-time solar wing deployment mechanism will cause safety hazards in the satellite maneuvering process.
