Solar panel pointing and positioning mechanism

Abstract

The invention relates to a pointing and positioning mechanism, and in particular relates to a solar panel pointing and positioning mechanism. The mechanism comprises a supporting seat, a rotary driving mechanism I, a rotary driving mechanism II, a gear box and a mounting plate, a right connecting shaft and a left connecting shaft are arranged on the two sides of the gear box respectively, and the right connecting shaft and the left connecting shaft are rotationally connected with the supporting seat; a pendulum shaft is arranged at the top of the gear box, the mounting plate is rotationally connected with the pendulum shaft, and the mounting plate is used for mounting a solar panel; the rotary driving mechanism I and the rotary driving mechanism II are arranged on the two sides of the supporting seat and connected with the right connecting shaft and the left connecting shaft correspondingly; when the rotary driving mechanism I and the rotary driving mechanism II are driven in the same direction at the same speed, the solar panel performs pitching action; and when the rotary driving mechanism I and the rotary driving mechanism II are reversely driven at a constant speed, the solar panel rotates. The mechanism has two degrees of freedom, not only can enable the solar panel to adapt to a complex working mode, but also has the characteristics of small size, light weight and high driving index.

Description

technical field [0001] The invention relates to a pointing and positioning mechanism, in particular to a solar sail panel pointing and positioning mechanism. Background technique [0002] In recent years, micro-satellites have developed rapidly. Not only has the number of launches increased year by year, but the payload has also become larger and larger, and its demand for energy has also gradually increased. The energy of microsatellites is generally provided by solar panels. The early solar panels were generally fixed relative to the satellite body. With the development of satellites, solar panel pointing (drive) mechanisms appeared. The pointing mechanism of the solar panel can make the normal line of the solar panel coincide with the sun's rays, thereby increasing the output power of the power supply. The existing solar panel pointing mechanisms generally only have one degree of freedom, and there are few solar panel pointing mechanisms with two degrees of freedom that ...

AI Technical Summary

Problems solved by technology

The existing solar panel pointing mechanisms generally only have one degree of freedom, and there are few solar panel pointing mechanisms with two degrees of freedom that have passed the assessment, and the one-degree-of-freedom pointing mechanism of the solar panel cannot adapt to complex working modes, so research The solar panel pointing mechanism with two degrees of freedom is of great significance
