SUN TRACKING MECHANISM

摘要

A sun tracking mechanism is provided for solar power generation, including a power unit, a linear actuator and at least two universal joints. The sun tracking mechanism outputs an angle of high precision by two axial directions provided from the universal joints, the power unit and the linear actuator. A solar power module disposed on the sun tracking mechanism generates electricity in the best light incident angle. In addition, the linear actuator provides an auxiliary supporting force to improve the wind-resistant capability.

主权项

1. A sun tracking mechanism, comprising:
a base; a first universal joint; a second universal joint; a pole having a fixing end fixed to the base and a connecting end connected to the first universal joint; a power unit disposed on the connecting end of the pole for providing a transmission force to the first universal joint; a linear actuator having a first end connected to the second universal joint and a second end connected to the base and being switched between a stretching state and a contracted state; and a plate having a first surface pivotally connected to the first universal joint and the second universal joint and a second surface opposing the first surface, wherein the first universal joint allows the plate to rotate around a first axial direction and/or a second axial direction, wherein the plate rotates around the first axial direction with the first universal joint as a pivot when the power unit provides the transmission force to the first universal joint, and rotates around the second axial direction with the first universal joint as the pivot when the linear actuator is switched between the stretching state and the contracted state.
