Abstract

The invention discloses a flexible solar wing unfolding mechanism with a high unfolding-folding ratio. The flexible solar wing unfolding mechanism comprises a bottom plate, a shear fork rod assembly, a top plate and a solar blanket assembly; the unfolding mechanism further comprises a driving assembly integrated on the bottom plate; the driving assembly is provided with a driving motor and a transmission gear, and the transmission gear extends to the upper part of the bottom plate; and the driving assembly is in transmission connection with the shear fork rod assembly through the transmission gear and drives the shear fork rod assembly to be unfolded so as to drive the solar blanket assembly to be unfolded. The unfolding mechanism is simple in structure, high in reliability and small in mass; most structural parts in the mechanism are made of spaceflight-grade hard aluminum alloy and carbon fiber composite materials, the mechanical structure is simple and not numerous and jumbled, and the structural parts are subjected to lightweight design improvement on the premise that the strength and vibration requirements are guaranteed; and the unfolding mechanism is low in manufacturing cost and material price, structural parts are simple in structure and convenient to manufacture, the shear fork rod assembly drives the solar blanket assembly to move, and the unfolding mechanism has the advantages of being light in weight, small in folding size, large in unfolding span and high in unfolding and folding ratio.

Description

technical field

[0001] The invention relates to the field of aerospace technology, in particular to a flexible solar wing deployment mechanism with a high expansion-to-contraction ratio, which is suitable for folding flexible solar wings. Background technique

[0002] The solar wing deployment mechanism is an important part of the solar wing, which is mainly used for the constriction, deployment and support of the solar blanket. The role of the unfolding mechanism is to gather the solar blanket to meet the stiffness requirements and launch envelope during the satellite launch phase, and to ensure that it does not cause violent vibrations to damage the solar blanket or other stand-alone units on the satellite. After entering orbit, the solar blanket can be smoothly unfolded and locked. Provide support for the unfolded solar blanket, and ensure that the solar blanket does not hook and interfere with various parts of the satellite during the unfolding process, and also meet the...
