User is normal on this mouse pad 1 to be used in the process of wireless mouse 12, and wireless mouse 12 can move up and down on mouse pad 1, when the magnetic field of electromagnetic induction module 3 alternation above mouse pad 1 time, namely can produce alternating current in coil.N pole on mouse pad 1 and the spacing between S pole are equal steady state values, spacing between this spacing with each leg of electromagnetic induction module 3 superimposed layer siliconized plate 9 is equal, during to ensure that electromagnetic induction module 3 moves in alternating magnetic field, form closed magnetic circuit, produce maximum flux change, in coil 10, obtain the highest alternating current of electric pressure.
The first half (forward) of ac power waveform can be charged to super capacitor 7 by commutation diode, and the latter half (negative sense) of ac power waveform can be charged to super capacitor 7 by commutation diode.This rectification module 4 adopts two commutation diodes to charge to two super capacitors 7 respectively, the pressure drop of loss on rectification module 4, four diodes of ratio bridge rectifier circuit give the pressure drop of electric energy storage device charging on commutation diode little one times, because the quantity of diode has lacked one times.Further, the germanium tube that the present invention adopts tube voltage drop little, and the silicone tube of non-generic, therefore, can be reduced to about the 0.2-0.5v of novel rectifying circuit by the pressure drop of common rectifying bridge type circuit about 1.4v; Significantly improve the efficiency of electricity collection.

Super capacitor 7 is when energy pulse charging repeatedly, and without any adverse effect, and rechargeable battery or lithium ion battery often require constant voltage or electric current when charging, and when energy pulse charging repeatedly, its life-span will have a greatly reduced quality.
Super capacitor 7 is non-maintaining, do not have corrosivity acid solution, can weld (battery does not contact problem loosely like that), and can be the use that China saves a large amount of one-shot batteries, thus reduce one-shot battery to the pollution of environment, is a kind of green energy resource of environmental protection.
The state-of-charge of super capacitor 7 and voltage form simple funtcional relationship, are easy to accurately detect dump energy.And battery is difficult to accurately detect dump energy.Therefore, at the roller envisaged underneath one small LCD liquid crystal display 11 of top cap of mouse, in order to indicate the remaining electricity of super capacitor 7.Full electricity is that 5 lattice points are bright, and voltage is about 2v, when voltage arrives 1v, is that lattice point is bright and glimmer, is in deficient electricity condition, and starts audible alarm simultaneously.Mouse on market is common carries out with emitting led power on instruction and low-voltage warning, but uses people's general attention power of mouse to concentrate on computer screen, is not easy the pilot lamp signal seen on mouse.And carry out with fainter voice signal power on instruction or deficient electric alarm better effects if.Adopt piezo buzzer 14 lower than emitting led power consumption, warning effect is better.Can be used alone LCD liquid crystal display 11 and carry out electricity display, also can be used alone piezo buzzer 14 and carry out power on instruction and low-voltage warning, also both can cooperate use.
Usually, similar EM induction system is difficult to single electrical storage device to be charged to more than 1.5v, needs boost module just can reach 1.5v voltage required by mouse, and the interpolation of boost module can the electric energy service efficiency of reduction whole system in various degree.Two super capacitors 7 in designed rectification and charging circuit are just in time series connection when powering to external circuit.The positive pole of two super capacitors 7 of series connection and negative pole drawn from position as shown in Figure 1, output voltage can be made double, and the total capacitance value simultaneously after series connection becomes 1/2nd (if two capacitance size are the same) of single electric capacity.Namely this design reaches the object of boosted output voltages when in use losing without any energy, be better than the method for designing through boost module boosting, can give wireless mouse and other small area analysis load supplyings of supply voltage 1.5-3v completely.For preventing the voltage that produces in power storage module excessive, at positive pole and a negative pole exit stabilivolt in parallel of two super capacitors 7 of series connection, to make output voltage stabilization below the highest use voltage of load.In test products, wireless mouse 12 of the present invention moved left and right 10 back and forth on mouse pad, can when departing from mouse pad 1 of this invention, for normal more than 20 minutes of wireless mouse 12.If wireless mouse 12 of the present invention is moved left and right 10 back and forth by user on mouse pad 1, and in use procedure thereafter, do not depart from the mouse pad 1 of this invention, but then its power storage can be reached self-sufficiency completely, can continue to use, unless run into the situation that wireless mouse leaves standstill for a long time, the electric energy stored can be exhausted, and on mouse pad 1, again move left and right 10 back and forth, can continue again to use.Therefore, wireless mouse 12 of the present invention can realize the self-sufficient of electric energy completely in the process of the normal rolling mouse of user.
