Abstract

The invention discloses a driving device for a solar cell array, which comprises: an A-axis mechanism driving rolling rotation and a B-axis mechanism driving pitching motion. The A-axis mechanism includes: an A-axis motor, a reducer, and a drive shaft, and a power and signal transmission device is arranged on one side of the drive shaft. The transmission of the A-axis motor through the drive shaft enables the solar array to achieve directional tracking of the rolling direction to the sun within the range of ±360°. The B-axis mechanism includes: a B-axis motor, a reducer, and a flexible spline of the reducer is connected in rotation with a support shaft. In the B-axis mechanism, the motor is decelerated by the reducer and the torque is amplified, so that the solar array can realize the sun orientation in the pitch direction within the range of ±90°. The invention solves the problem that the solar battery array cannot always be aligned with the sun's rays, and achieves beneficial effects of improving electric energy transmission and tracking precision.

Description

technical field [0001] The invention relates to a driving mechanism, especially a driving device for solar cell arrays to track the sun directionally and simultaneously transmit electric power and measurement signals sent by the solar cell arrays to power supply equipment in the aircraft cabin. Background technique [0002] At present, domestically used devices for driving solar cell arrays only have a single-degree-of-freedom driving form, and there is no two-degree-of-freedom driving mechanism similar to the present invention. The shortcomings of the single-degree-of-freedom solar cell array drive mechanism are mainly manifested in: [0003] a. The solar cell array cannot be kept perpendicular to the sun's rays, and the deviation between the two cannot be eliminated, so that the solar cell array cannot obtain the best lighting effect, resulting in a large loss of power generation efficiency, requiring satellites to increase the area of ​​the solar cell array To make up fo...
