Problems solved by technology

There is friction and wear in the conductive slip ring, the life is low, and the cost is high; in the existing solar panel drive mechanism, the ring-brush friction pair of the disc ring or the column ring is used to realize power and signal transmission
The conductive ring has the problems of complex structure, high cost, low reliability and heavy weight
In addition, the conductive ring generally needs to use a non-metallic insulating structure as a supporting structure, resulting in heavy weight and low rigidity, which affects the performance of the entire star

Abstract

The invention relates to a swing type solar panel driving mechanism. The structure of the swing type solar panel driving mechanism comprises a rotary transformer, a stepping motor, a harmonic gear, anoutput shaft, a shell and a torsional pendulum cable; the fixed parts of the stepping motor and the harmonic gear are mounted on the shell; the stepping motor is connected with the harmonic gear, theharmonic gear is used for reducing the rotating speed of the stepping motor and transmitting the torque of a rotating shaft of the stepping motor to the output shaft, and the output shaft is used forbeing connected with an external solar panel and driving the solar panel to swing; the rotary transformer is used for measuring the rotation angle of the output shaft; and one end of the torsional pendulum cable is connected to an external actuating mechanism, and the other end of the torsional pendulum cable is connected to the shell of the drive mechanism. According to the swing type solar panel driving mechanism, a method for realizing electric signal transmission by replacing a slip ring with the torsional pendulum cable is adopted, and low weight, high rigidity, high reliability and longservice life are realized.

Description

technical field [0001] The invention relates to a swing-type solar sail panel drive mechanism, which belongs to the technical field of space pointing and tracking mechanisms. Background technique [0002] The driving mechanism of the solar panel generally uses a conductive slip ring to realize the electrical connection between the rotating solar wing and the star. There is friction and wear in the conductive slip ring, the life is low, and the cost is high; in the existing solar panel drive mechanism, the ring-brush friction pair of the disk ring or the column ring is used to realize power and signal transmission. The conductive ring has the problems of complex structure, high cost, low reliability and heavy weight. In addition, the conductive ring generally needs to use a non-metallic insulating structure as a supporting structure, resulting in heavy weight and low rigidity, which affects the performance of the entire star. Contents of the invention [0003] The technic...
