Structure does not limit herein as long as driving voltage can be provided for engine pack 10.Wherein, it is just received below with friction
Rice generator 20 is illustrated for the friction nanometer power generator for independent friction layer model.
Specifically, for the friction nanometer power generator of independent friction layer model, specific structure be may refer to shown in Fig. 3,
Wherein, friction nanometer power generator 20 may include: sliding friction layer 21 and the first electricity that is opposite with sliding friction layer 21 and setting
Pole 22；First electrode 22 may include: the first sub-electrode 22a and second sub electrode 22b arranged in parallel and insulation set；First
An a side surface and second sub electrode 22b side surface towards sliding friction layer 21 of the sub-electrode 22a towards sliding friction layer 21
It is in the same plane；First sub-electrode 22a and second sub electrode 22b is connected with two input terminals of rectifier 30 respectively.It is logical
It crosses sliding friction layer to slidably reciprocate on the first surface sub-electrode 22a and the surface second sub electrode 22b, to alternately sub with first
Electrode 22a and second sub electrode 22b contact, thus by the first sub-electrode 22a and second sub electrode 22b by voltage output to whole
It flows in device 30；To which friction nanometer power generator 20 can be realized by simple structure and provide work institute for engine pack 10
The driving voltage needed.
In embodiments of the present invention, when selecting the material of sliding friction layer 21, it can choose strong negative electrical charge affinity
Material, this kind of material when relative motion occurs with it is stronger absorb negative electrical charge (electronics) ability, as FEP, PDMS,
The dielectric materials such as PET；It is also an option that strong positive charge affinity material, this kind of material when relative motion occurs with compared with
The ability of strong absorption positive charge.And when selecting the material of first electrode 22, it can choose metal, conductive carbon material, conduction
The conductive materials such as polymer or conductive oxide, do not limit herein.
In the specific implementation, sliding friction layer 21 is in 22 surface of first electrode (such as the first sub-electrode 22a and second sub electrode
The surface 22b) sliding when, sliding friction layer 21 can be in contact with 22 surface of first electrode, it is also possible that sliding friction layer 21
There is certain distance between 22 surface of first electrode, but the distance should not be too large, and can be adjusted according to the actual situation, this
Place does not limit.
In addition, the spacing of the first sub-electrode 22a and second sub electrode 22b in the horizontal direction, usually can be set to 2 millis
- 5 millimeters of rice, but it is not limited to this, can be adjusted according to the actual situation, and does not limit herein.
Below with reference to structure shown in Fig. 3, for independent friction layer model friction nanometer power generator working principle into
Row is explained.
It is shown in Figure 4 by taking sliding friction layer is by the material of strong negative electrical charge affinity as an example, at stage (1), in cunning
Dynamic friction layer 21 is in contact with the first sub-electrode 22a, since sliding friction layer has strong negative electrical charge affinity, so sliding rubs
It wipes layer and is having negative electricity towards mono- side surface the first sub-electrode 22a, and since negative electrical charge is transferred in sliding friction layer, so that the
One sub-electrode 22a has positive charge；At this point, the charge of the transfer between the first sub-electrode 22a and second sub electrode 22b is essentially
0。
At stage (2), sliding friction layer is mobile to second sub electrode 22b direction, in sliding friction layer and second
The surface of sub-electrode 22b contacts, and when being in contact simultaneously with the first sub-electrode 22a, since sliding friction layer has strong negative electrical charge
Affinity can absorb negative electrical charge from the first sub-electrode 22a and second sub electrode 22b respectively, so second sub electrode at this time
Negative electrical charge in 22b can be also transferred in sliding friction layer, so that second sub electrode 22b has positive charge；Simultaneously as sliding
Frictional layer is contacted with the surface second sub electrode 22b, so the contact area of sliding friction layer and the first sub-electrode 22a are reduced, is made
The positive charge obtained in the first sub-electrode 22a is reduced；Therefore, voltage is generated between the first sub-electrode 22a and second sub electrode 22b
And it exports.Also, voltage is generated between the first sub-electrode 22a and second sub electrode 22b, it can be with sliding friction layer and the second son
The increase of the contact area of electrode 22b and be gradually increased, until enter stage (3) when, i.e., sliding friction layer completely with first son
The surface of electrode 22a separates, and is in contact completely with second sub electrode 22b, the first sub-electrode 22a and second sub electrode 22b it
Between the voltage that generates reach positive maximum value.
However, as sliding friction layer is moved to the first sub-electrode 22a direction, such as stage (2), first
Voltage is generated between sub-electrode 22a and second sub electrode 22b to be gradually reduced again, until when returning to the state in stage (1), the first son
Voltage between electrode 22a and second sub electrode 22b is that negative sense is maximum.
Therefore, the slidably reciprocating between the first sub-electrode 22a and second sub electrode 22b with sliding friction layer, alternately
Ground is in contact with the first sub-electrode 22a and second sub electrode 22b, thus between the first sub-electrode 22a and second sub electrode 22b
Generate voltage simultaneously export, for engine pack work and driving voltage is provided, drive engine pack work.

For nano generator, frequency that sliding friction layer 21 slidably reciprocates on the first surface sub-electrode 22a and the surface second sub electrode 22b
Rate is in 0.25Hz between 0.6Hz.
Relational graph between the revolving speed of engine pack 10 as shown in Figure 5 and the sliding frequency of sliding friction layer 21, by
Figure it is found that with 21 sliding frequency of sliding friction layer increase, the revolving speed of engine pack 10 is consequently increased, and works as sliding frequency
When for 0.5Hz, it is 1050 revs/min that the revolving speed of engine pack 10, which reaches maximum value,；And when sliding frequency continues growing, by
It being influenced in by factors such as air drag, the revolving speed of engine pack 10 will not increase with the increase of sliding frequency again,
And it is held in a stable state.Therefore, as long as controlling the sliding frequency of sliding friction layer 21 in 0.25Hz-0.6Hz
When, steady and continuous operating can be realized in engine pack 10, realizes friction nanometer power generator 20 and drives engine pack 10
It works normally.
Optionally, in order to guarantee that engine pack 10 can normally work, in embodiments of the present invention, friction nanometer hair
The output voltage of motor 20 is not less than 2 kilovolts.
Relational graph between 21 sliding distance of revolving speed and sliding friction layer of engine pack 10 as shown in FIG. 6, wherein
It is shown in fig. 6 the result is that being 0.0045m with the area of sliding friction layer 212When between 0.0135m2, the first sub-electrode 22a and
The area of second sub electrode 22b is 0.0135m2For tested obtained from, and be parallel to sliding friction layer 21
On moving direction, the length of sliding friction layer 21 is 90 millimeters, the length difference of the first sub-electrode 22a and second sub electrode 22b
It is 150 millimeters.
As seen from the figure, with the increase of 21 sliding distance of sliding friction layer, the revolving speed of engine pack 10 is consequently increased,
When sliding distance is 90 millimeters, it is 1100 revs/min that the revolving speed of engine pack 10, which reaches maximum value,；And when sliding distance after
It is continuous when increasing, due to being influenced by factors such as air drag and friction areas, the revolving speed of engine pack 10 will not again with
The increase of sliding distance and increase, and be held in a stable state.Also, sliding distance and output voltage are into just
Ratio, sliding distance is bigger, and the voltage that friction nanometer power generator 20 exports is higher.Therefore, as shown in connection with fig. 6 as a result, and
Relationship between sliding distance and output voltage, to guarantee that engine pack 10 can normally work, rub nanometer generating
The output voltage of machine 20 is needed not less than 2 kilovolts.
