Abstract

The invention discloses a cubic star deployable battery array capable of being folded many times and a method for unfolding the same, including a satellite frame, the two sides of the satellite frameare respectively connected with the deployment array by connecting devices, a deployment array includes a medial deployment array, the middle deployment array and the outer deployment array, one sideof the inner deployment array is connected with the satellite frame through a connecting device, the other side is connected to one side of the intermediate deployment array through a first hinge connecting device, the other side of the intermediate deployment array is connected to the outer deployment array through a second hinge connecting device, each side deployment array can be unfolded and folded and can be locked and unlocked in a folded state by a locking and unlocking mechanism when in a folded state, the folding and locking mechanism of the invention is simple in structure, simple indeployment mode, high in efficiency and high in reliability, and can provide two to three times more illuminated areas than a conventional monolithic deployed cubic star battery array after deployment, and can provide sufficient electric power for a high-power load mounted on a cubic satellite.

Description

technical field [0001] The invention belongs to the technical field of satellites, and in particular relates to a foldable cubic star expandable battery array and an unfolding method thereof. Background technique [0002] In recent years, due to the rapid development of CubeSat technology, the CubeSat industry has gradually become the main driving force and important development field for the rapid development of space activities in the world, and is gestating a major change in future space development. With the development of microelectronics, sensors, and nanotechnology and the innovation of satellite design ideas, CubeSat has developed from innovative concepts, system design, technology implementation, and flight experiments to specific space applications, and the number of launches has also increased rapidly. [0003] The power supply is a very important subsystem of CubeSat, including battery packs and solar arrays. They provide the required working energy for the cube...
