Abstract: A driving pinion drives two driven gears which are engaged with the driving pinion to rotate. Two drive bars which are fixed on the driven gears at a set radius respectively are inserted into two elongated openings of a frame which is pivoted on the driving pinion to make the frame seesaw, and then to make a coupler link which is borne on a stand, seesaw synchronously via a rocker mechanism having a four-bar linkage which is pivoted on both ends of the frame. Also, the stand is connected to an inclination adjusting mechanism, so that the inclination of the stand can be changed with respect to a horizontal plane.

Abstract: The present invention proposes a solar panel mounting structure comprises: a frame and three gears. The frame has a first opening, a second opening and a third opening, and connects to a solar panel; the third opening is aligned with the first opening and the second opening. The first gear has a first bar; the first bar works in the first opening. The second gear has a second bar; the second bar works in the second opening. The third gear has an axle, and locates between the first gear and the second gear and gearing therein; the axle works in the third opening; thereby, the solar panel seesaws when the third gear turns.
