Unfoldable solar battery array and pressing releasing mechanism thereof

Abstract

The invention relates to an unfoldable solar battery array and a pressing releasing mechanism thereof. The unfoldable solar battery array comprises the pressing releasing mechanism and a solar batteryarray which are arranged on a spacecraft; the pressing releasing mechanism comprises a storage box plate; one end of the storage box plate is hinged to the spacecraft through a box plate hinge; a connection separating mechanism capable of being automatically separated from the spacecraft is arranged at the other end of the storage box plate; the solar battery array comprises multiple base plates;the adjacent base plates are hinged to each other through interplate hinges; solar cells are arranged on the base plates; a one-dimensional unfolding device is also arranged on the solar battery array; one end of the unfolding device is arranged at one end of the solar battery array; the other end of the unfolding device is arranged at the other end of the solar battery array; and one end of thesolar battery array is also connected to the spacecraft. According to the unfoldable solar battery array and the pressing releasing mechanism thereof, the unfolding area is large, and the folding andunfolding ratio is high.

Description

technical field [0001] The invention relates to a solar battery array of a spacecraft, in particular to an expandable solar battery array and a pressing and releasing mechanism thereof. Background technique [0002] With the improvement of our country's national defense needs and the vigorous development of civil aerospace, the demand for on-orbit energy power of spacecraft is increasing, and a larger area is required for solar arrays, the core power supply equipment of spacecraft. However, limited to the envelope of the fairing of the launch vehicle, the large-area solar cell array needs to adopt a deployable configuration design to achieve the effective compression and overload of the launching section in the folded state, and reliable release after orbiting to implement deployment and lock to maintain the shape. the goal of. Traditional deployable solar cell arrays and their compression and release mechanisms include body-mounted, single-panel, multi-panel, and other con...

However, limited to the envelope of the fairing of the launch vehicle, the large-area solar cell array needs to adopt a deployable configuration design to achieve the effective compression and overload of the launching section in the folded state, and reliable release after orbiting to implement deployment and lock to maintain the shape. the goal of

Traditional deployable solar cell arrays and their compression and release mechanisms include body-mounted, single-panel, multi-panel, and other configurations. The maximum folding-to-expanding ratio is about 1 / 9, which is difficult to further improve and cannot solve the problem of solar cells. The contradiction between the large area of ​​the array and the high fold-to-expand ratio
