In figure：1st, first friction unit, the 2, second friction piece, 3, electrode support, 4, rolling bearing, 5, generator unit.
Embodiment
Embodiment 1
As shown in Figure 1, as a generator unit 5, first friction unit 1 is all packaged with insulator (polyamides for two covering of the fan surfaces
Imines) metal AI, internal metal AI is connected with shaft, as rotor；Second friction piece 2 is metal AI, as stator, together
When also serve as supporter and one of electrode.3 be electrode support, and 4 be rolling bearing.Two surfaces of first friction unit 1
All be rubbing surface, therefore the friction of single triboelectricity unit produces twice that electric charge is approximately common gliding model, this approximately twice as
Electric charge be effectively increased the quantity of electric charge shifted in circuit.
The transfer process of electric charge is as shown in Figure 2.Before rotation, 1 and second friction piece 2 of first friction unit is completely superposed, and is turned
Son and stator do not have relative motion, and the surface of the two does not rub the electric charge of generation, and when rotor starts to rotate, contact surface is by rubbing
Wipe, two surfaces of polyimides carry negative electrical charge, and the metal AI surfaces of the second friction piece 2 carry corresponding positive charge.The
The part that two friction pieces 2 are overlapped with first friction unit 1, the positive and negative charge of generation overlap, and external electrical field is not contributed.It is and misaligned
Part, for first friction unit 1, there is irremovable negative electrical charge on surface, under the action of electrostatic induction, the electrode A I of the inside
On have the trend of induced positive；For the second friction piece 2, due to being separated with first friction unit 1, the separated part band in surface is just
Electricity, there is the trend of sensing negative electrical charge.At this time, for two electrodes, there are an electrical potential difference, if external circuit closes, electricity
Son can displacement formation electric current.
When device is since Fig. 2 starting figure, through turn to it is full opening of during, one direction of current direction；When
Device is opened from complete, and to progressively collapsing, during eventually passing back to initial position, electric current is reverse；Therefore, for there is 4 hairs
The device of electric unit, when device rotates a circle, current direction changes 8 times, and current waveform figure has 4 cycles.With outside the device,
Plus a rectifier bridge, alternating current is changed into direct current, can light 11 LED of series connection, in the present embodiment, not to contact
AI and polyimide surface carry out any processing, better if carrying out microprocessor to rubbing surface directly using commercial product.

Share, and the two sides of electrode can serve as rubbing surface, and contact area is significantly increased in limited volumetric spaces, to carrying
Current value is risen to be very helpful.
When the effective current value increase of generator, the application range of friction generator can be greatly expanded.
The electronic transfer process of the present embodiment as described in Example 1, when the rotor is turning, the transfer process of electric charge and
The process of Fig. 2 descriptions is consistent, can produce the current value much larger than single friction generator.
The present invention makes simply, of low cost.Inspiration according to the invention, stackable more friction electrodes, is increased with this
Add the current value of yield.The implementation of the program can significantly solve the less technical barrier of friction generator current value, be that one kind can
With widely applied friction generator.
Explanation of the example disclosed in this invention just for technical scheme, it is impossible to as to present disclosure
Limitation, the change of those skilled in the art on the basis of the present invention is still within the scope of the present invention.
