AI Technical Summary

Technical Problem

Due to the fixed state, the existing commercial microsatellite solar cell array cannot effectively track the sun, resulting in low power generation efficiency and cannot meet the growing demand for efficient energy.

Method used

A solar array steering mechanism for commercial microsatellites is designed, including a basic frame, a driving mechanism, a transmission mechanism and a connecting member. The connecting member is driven to rotate through the driving mechanism and a transmission mechanism to realize the dynamic steering of the solar array.

Benefits of technology

The time for the "maximum" light-receiving area of ​​the solar cell array is extended, the energy acquisition efficiency of the entire star is improved, the satellite needs for more energy, and the working performance and reliability of the steering mechanism are improved.

Abstract

The invention discloses a solar cell array steering mechanism of a commercial microsatellite and a steering control method of the solar cell array steering mechanism. The steering mechanism comprises a basic frame, a driving mechanism, a transmission mechanism and a connecting piece. The connecting piece is rotationally connected to the basic frame, and an assembling structure capable of installing a solar cell array is arranged on the connecting piece; the driving mechanism is arranged in the basic frame, and the driving mechanism is in transmission connection with the connecting piece through a transmission mechanism so as to drive the connecting piece to rotate. The device is applied to the technical field of commercial microsatellites, the solar cell array can be driven to steer in the operation process of the microsatellites, then the time of the maximum illuminated area of the solar cell array is prolonged, the whole satellite obtains more energy, and meanwhile the device is compact in structure, compact in transmission, small in appearance size, light in whole machine weight, high in reliability and suitable for popularization and application. The cost of the solar cell array steering mechanism can be effectively reduced, and the working performance of the steering mechanism can be improved.
