Solar array drive mechanism

Abstract

The invention provides a solar cell array driving mechanism. The solar cell array driving mechanism is used for providing a driving function and a transmission function for a solar cell array, the solar cell array driving mechanism comprises an actuator, a slip ring stack and a measurement module, the actuator is used for providing the driving function for the solar cell array, and the measurementmodule is used for measuring the motion state of the solar cell array; the solar cell array comprises a solar cell array electrical assembly, the slip ring stack is electrically connected with the solar cell array electrical assembly through an electrical connector of an output shaft section, and power output by the solar cell array electrical assembly is transmitted to the satellite body throughthe slip ring stack. The slip ring stack comprises a plurality of slip ring modules, all the slip ring modules are connected through mechanical interfaces, and the number of the slip ring modules isincreased or decreased according to different task requirements so as to achieve the transmission function of different powers of the solar cell array electrical assembly.

Description

technical field [0001] The invention relates to the technical field of solar battery arrays, in particular to a solar battery array driving mechanism. Background technique [0002] The solar cell array, also known as the solar panel, belongs to the satellite energy stand-alone unit and is responsible for the power supply of the satellite. For three-axis stabilized satellites, the solar panels need to be oriented to the sun through the drive mechanism to maximize energy acquisition, and the electric energy obtained by the solar panels needs to be transmitted to the star through the slip ring of the drive mechanism. [0003] However, for different space missions, satellites have different energy requirements, so for the drive mechanism, it is necessary to design slip ring assemblies with different specifications for different missions. In the general spacecraft stand-alone development process, the custom development of a new product needs to go through three stages: scheme de...
