Embodiment
Referring to Fig. 1 and 2, little upper casing 1, rotating disk 2, weight 3, gearwheel 4, small gear 5, micro generation unit 6 and the base 7 of being provided with of the utility model.Rotating disk 2, weight 3, gearwheel 4, small gear 5 and micro generation unit 6 are located on the base 7,3 weights 3 evenly are located at the edge of rotating disk 2 by 60 degree of being separated by, gearwheel 4 is located at the bottom of rotating disk 2, and rotating disk 2 is formed one with weight 3 and gearwheel 4, forms a labile equilibrium mechanical component.Micro generation unit 6 is located between rotating disk 2 and the base 1, and the arbor of micro generation unit 6 is fixed on base 7 centers.Small gear 5 is located at the microgenerator periphery, and small gear 5 drives the small gear 5 of being located at micro generation unit periphery with gearwheel 4 engagements, the gearwheel of being located on the rotating disk 24.
The micro generation unit is provided with at least 2 microgenerators.
In case extraneous the vibration, the labile equilibrium mechanical component of the utility model inside rotates under action of gravity, and the gearwheel on the rotating disk drives the small gear of micro generation unit, and the electric current that sends is exported from power output end.The forms of electricity generation of micro generation unit adopts induction, and the coil and the magnet of generator inside do relative motion, and cutting magnetic line produces induced current.Because turning to of rotating disk can up time or inverse time, the rotating speed speed is relevant with the vibration intensity, so little vibrating power-generation device output current value fluctuates, and current direction (polarity) also can change.
The utility model can be used as power supply and supplies with microminiature electricity consumption setting, and total current is about 0～10mA.
