A split type two-axis drive mechanism

Abstract

The invention discloses a split-type two-axis driving mechanism, which includes an A-axis driving mechanism, a folding assembly, a B-axis driving mechanism, and a connecting frame; wherein, the A-axis driving mechanism and the B-axis driving mechanism adopt a split design, and the A and B-axis The driving mechanism can fully inherit the existing mature single-axis driving mechanism technology status, with high product maturity, simple structure, and high reliability. The A-axis driving mechanism is connected with the B-axis driving mechanism through a folding component, which improves the driving mechanism and solar cells. The integration of the array; the output shaft of the A-axis drive mechanism is connected to one end of the folding assembly, the other end of the folding assembly is connected to the connection frame, the connection frame is fixedly connected to the solar cell array, and the output shaft of the B-axis drive mechanism is connected to the solar cell through the connection frame array; the A-axis drive mechanism drives the B-axis drive mechanism, the folding assembly, and the solar cell array to achieve 360° orientation to the sun, and the B-axis drive mechanism is used to drive the solar cell array to achieve swing.

Description

technical field [0001] The invention belongs to the application field of satellite technology, and in particular relates to a two-axis driving mechanism of a split solar cell array. Background technique [0002] The driving and transmission of the satellite solar cell array is generally realized through the driving mechanism. The driving mechanism, as the connection device between the solar cell array and the star, is responsible for driving the solar cell array to align with the sun, and at the same time transmit the current and signal converted by the solar cell array to the star. [0003] The general driving mechanism only needs one degree of freedom, but for some complex orbits or satellites with special application purposes, the incident angle of the battery array to sunlight changes greatly within one orbital period, and the single-degree-of-freedom driving mechanism can no longer guarantee a good solar environment. The incident angle of light requires the use of a two-...

Problems solved by technology

[0003] The general driving mechanism only needs one degree of freedom, but for some complex orbits or satellites with special application purposes, the incident angle of the battery array to sunlight changes greatly within one orbital period, and the single-degree-of-freedom driving mechanism can no longer guarantee a good solar environment. The incident angle of light requires the use of a two-degree-of-freedom drive mechanism. At present, the various spacecraft that have been launched in my country, the solar panels mostly use a single-degree-of-freedom drive mechanism, and the two-degree-of-freedom drive mechanism is rarely used, and most of them are two-axis integrated design , Product stability, inheritance, versatility are poor, and the weight is heavy
