Because the defect of prior art, and the wireless mouse energy supply dress provided based on technique scheme
Put, present invention also offers a kind of wireless mouse automatic energy supply method of piezoelectric type, use the wireless of the method
Mouse, powers without external cell, and can realize the self-energy supply of mouse by clicking on mouse.Concrete bag
Include following steps:
S1: piezoelectric ceramics cantilever beam, when the button of mouse is pressed, collects what mousebutton click vibrations produced
Mechanical energy, and produce alternating current；
The alternating current that the piezoelectric ceramics cantilever beam that S2: energy collection module receives produces, through full-wave bridge rectifier
And filtering, and it is converted into unidirectional current；
S3: if the energy collected during work is not enough, then self-charging battery system is as the power supply of mouse；
If storage capacitor collects enough electricity, then powered by storage capacitor, and charge to self-charging battery system.
In the technical program, piezoelectric ceramics cantilever beam is arranged at below mousebutton；When click,
The vibration of piezoelectric ceramics cantilever beam forms mechanical energy and is converted into AC energy, and energy collection module will exchange a little
Being converted into direct current energy, if the energy now collected is not enough, then self-charging battery system is using the confession as mouse
Electricity power supply；If now storage capacitor collects enough electricity, then powered by storage capacitor, and give self-charging electricity
Cell system charges；This technical scheme is by clicking on mouse, it is achieved mouse oneself's energy supply.
To sum up, the beneficial effects of the present invention is: utilize mousebutton to click on, piezoelectric ceramics cantilever beam is by Mus
The mechanical energy produced when punctuate hits is electric energy；Piezoelectric ceramics cantilever beam can produce higher energy and convert effect
Rate, has relatively low resonant frequency simultaneously, and structure is the simplest, it is adaptable to mouse performance this outside
The occasion that boundary's excitation is less, Oscillation Amplitude is relatively low；Meanwhile, piezoelectric ceramics cantilever beam is placed in mouse pulley
Below key and the radial direction of side switch, improving changes mechanical energy further is the efficiency of electric energy, improves electric energy and produces
