Abstract

The invention relates to a two-degree of freedom inertial driving mechanism utilizing photovoltaic power supply, which comprises a photovoltaic assembly (7), a driving box (8) comprising a driving control circuit as well as a load(9), four piezoelectric stack elements and four counterweights, wherein the photovoltaic assembly(7), the driving box (8) and the load (9) are integrated into a main body and contacted with a working surface (10), and the four piezoelectric stack elements are respectively located in the front, at the back, on the left and the right of the main body. One ends of the four piezoelectric stack elements are connected with the main body, and the other ends are connected with the four counterweights. Under the lighting of sunlight (6), the photovoltaic assembly (7) generates direct current, and asymmetrical voltage signals are generated to excite the piezoelectric stack elements after the direct current is supplied to the driving control circuit in the driving box (8), therefore, the inertial driving mechanism can make continuous displacement in an x-y plane.

Description

technical field [0001] The invention relates to a photovoltaic power generation and piezoelectric inertia drive device. Background technique [0002] In recent years, the energy crisis caused by the shortage of fossil energy has gradually begun to affect human economic development and social life. This trend directly promotes the development and progress of renewable energy power generation, especially solar photovoltaic power generation technology. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. In addition to large-scale utilization methods such as grid-connected photovoltaic power generation and off-grid photovoltaic power generation, various tiny photovoltaic energy (watt-level) products (such as solar calculators, solar clocks, solar chargers, etc.) broaden. [0003] At the same time, the preparation technology of piezoelectric ceramic materials an...
