Detailed description of the invention
Further the utility model is described in detail below in conjunction with drawings and Examples.
See Fig. 2 a, the utility model is applied to a kind of two-wheel car, and compared with common electric three-wheel vehicle, this battery-driven car does not have the electrical motor of block construction; The function increasing journey system is only be battery pack electric energy supplement in setting logic state, and its electric energy supplementary device can be the system of internal combustion engine generator combination or the system of primary battery combination, or its combination; The work-based logic relation of described increasing journey system and battery pack, electric device as shown in Figure 2 b.
The basic design of electric device described in the utility model comprises stator unit 3a and rotor unit 3b, stator unit is formed by one group or some groups of good wire wounded cores, good wire uses copper cash or copper facing aluminum core line usually, magnetic core adopts common magnetic medium, such magnetic medium be known to the skilled person a kind of under magnetic fields internal state change and produce the material of stronger complementary field; Rotor unit is made up of magnetic conductive media solid or software shaped material, such magnetizer be known to the skilled person a kind of under magnetic fields internal state change and produce the material of backing field.Within the scope of the magnetic fields of the inner winding energising of stator unit, magnetizer rotor unit can be responded to magnetisation and be subject to its electromagnetic attracting force effect, the energising orientation independent of this magnetic effect and stator unit winding, the inner winding of stator unit is more, the permeability of magnetizer material is higher, and magnetic interaction is stronger.
As shown in fig. 4 a, when a rotor unit 3b is arranged on rim 6 outer rim, a stator unit 3a is fixed on the vehicle frame 4 of rim inner edge, relative air gap 3d is enough little in both motions, then rotor unit be energized with wheel convergence winding stator unit time, can be subject to electromagnetic attraction and make wheel accelerated movement, the electromagnetic force F suffered by rotor unit can be analyzed to coaxial normal 10 direction F
10with tangent line 11 direction F
11, wherein contributive around axle to rotor unit is tangential F
11; Rotor unit arranges relevant around between axle force area to stator unit, single column passes through the maxim in air gap rim interval around the core stator unit electromagnetism line of force, the two poles of the earth line 12 corresponding to electromagnetic pole is vertical to its normal 10 residing for rim (tangent line 11 corresponding to rim is parallel), as shown in Figure 3 a; The two poles of the earth line 12 that column also can be set to electromagnetic pole around core overlaps with normal residing for it 10, as shown in Figure 3 b, selects when this set-up mode is generally multiple stator unit combination arrangement; To the stator unit of matrix around core, its electromagnetic force is interval to the useful effect of rotor unit, is positioned at matrix around core both upper ends thereof just to the two ends scope of rim 6 inner edge, as shown in Figure 3 c.
Rotor unit is on rim during convergence stator unit, and it is a dynamic angle around the residing normal of axle motion and stator unit and the determined normal of axle
it is a particular point by the state that electromagnetic force F action direction suffered by air gap overlaps with around axle tangential direction, and now rotor unit and the determined normal of axle and stator unit and the determined normal of axle define an angle
the useful effect of stator unit electromagnetic force suffered by rotor unit is interval, is positioned at
to be 0 state be benchmark
in lane place (described ± relatively to define according to the hand of rotation of rim).When

The electric device actuation techniques scheme of the utility model battery-driven car is: power supply modulator is corresponding
the time domain energising of state, all the other time domain power-off; In this energising time domain, should select based on the design of economizing on electricity
even
time domain energising; Need the design making full use of rotor inertia of turning, can select
even
time domain energising; The break-make time domain of this drive current as shown in Figure 6 a, wherein T

2+ T
0) constitute the cycle T of Timing driver electric current; If
time domain energising, because showing as with braking force F between this state area
10be main, the optimization meaning of Design of power saving can be lost battery-driven car driving.When the utility model battery-driven car needs to increase electromagnetic force braking/brake function, power supply modulator provides the technical scheme of braking current to be: corresponding
the time domain of state,
be 0 and at least one time domain of being in away from state of rotor unit and stator unit be energized; In like manner, due to
?
considerable tangential electromagnetic force F is there is between state area
11, unhelpful to the optimization Brake Design of battery-driven car.
Described
according to stator unit, concrete scheme that (comprise combination arrange) and rotor unit arrange at rim be set at vehicle frame and determine, normally using
specific position judge the one foundation of power supply modulator work-based logic as sensing device;
be one to rim radian, air-gap separation, stator unit around the relevant value of the parameters such as core shape and arrangement thereof, have multiple theoretical model, should through test inhabitant area during specific design.The corresponding work-based logic exporting driving or braking current of power supply modulator both can be realized by ordinary tap control path, and CPU also can be adopted to programme in conjunction with power model group circuit realiration, or adopted large-scale integrated special chip to realize.
Above-mentioned power supply modulator according to
state, to the control of switching electricity, can approximate transform be that relative time controls, because
be 0 state and
be that 90 degree of states are aobvious state, power supply modulator can be sentenced by timing alignment and know
from 90 degree to 0 degree, i.e. (T
1+ T
2) time period, as long as setting T
1with T
2relative time, it is right to be namely similar to
the switching electric control of corresponding state; Such as control
the time domain energising of corresponding 90 degree to 45 degree, can be similar to and be set as: at (T
1+ T
2) time period initial 1/2 time domain energising, 1/2 time domain power-off afterwards; In like manner, control is worked as
the time domain energising of corresponding 30 degree to 0 degree, can be similar to and be set as: at (T
1+ T
2) time period initial 2/3 time domain power-off, afterwards 1/3 time domain energising; But (T
1+ T
2) time period is an amount relevant to vehicle wheel rotational speed, control with period
real-time status have deviation when speed change, because the corresponding θ of power supply modulator is that 0 degree of state is provided with time calibration, must gives and correcting in time in next cycle.
Concerning a stator unit 3a combines the simple analysis example of a rotor unit 3b, rotor unit is not in the electromagnetic force valid interval of stator unit around the axial period most of the time, first should consider T break period in preferred electric current timing cycles T during programming
0, and then preferred power-off time T
2with T current"on"time
1, improve the degree of utilization of electric energy, Fig. 6 b is a kind of sequential logic schematic diagram driving energising of this simple analysis example.
Fig. 7 a is the structural representation sketch of corresponding 8 rotor units of stator unit, stator unit rim swing circle π respectively with 8 rotor unit generation magnetic action, the sequential electric current theory that power supply modulator is corresponding is divided into 8 (T

As shown in Figure 9, in the rotation of wheel cycle, power supply modulator will provide 8 cycles for (T for two stator units respectively
1+ T
2+ T
0) sequential electric current, this combination proposes higher designing requirement to power supply modulator.4 stator units can be selected further to combine 10 rotor units, 6 stator units combine 12 rotor units, etc.In theory when H stator unit 3a and n rotor unit 3b unitized design, if power supply modulator is to the discrete power supply of H stator unit 3a winding, need corresponding design n*H electric current sequential, i.e. n*H (T
1+ T
2+ T
0) electric current sequential, programming will be very complicated; Therefore in the utility system design of multiple stator unit, preferred H stator unit winding electric series combination, or H stator unit winding is divided into some groups of external source modulator, the inside windings in series of such as 4 stator units, tap totally three external electric connection of power supply modulator of line are drawn in the middle of series connection winding, the difference of the differetial-potential that technically these three lines also can be utilized to compare between two, as the signal source that a kind of rotor unit and stator unit relative position differentiate, substitute the independent sensing unit arranged.
In theory, also at rim, several stator units on a rotor unit and vehicle frame can be installed and combine, though this equivalent arrangements can be implemented technically, but because of the cost of stator unit relatively high, not preferred scheme.
Power supply modulator can realize by ordinary tap circuit layout or pulse digit technology, preferred the latter, its fundamental functional modules generally comprises power converting circuit, the microprocessor of internal memory contain job procedure and signal input and output circuit, the sequential electric current of driver module output is correspondingly controlled by sensing unit 3c feedback signal, Dynamic controlling is carried out to electric device 3, its work-based logic such as Fig. 5 a shows, and Fig. 5 b is a kind of block combiner schematic diagram realizing the digital means logic of power supply modulator basic function.
The work-based logic transformation directive signal of power supply modulator normally obtains from the sensing unit 3c be connected in vehicle frame, sensing unit is not limited to use magnetoelectric induction winding or Hall element, also photoelectric encoder etc. can be used, when rotor unit moves around axial period, the rate of change that sensing unit can obtain electric current (voltage) feeds back to power supply modulator, and power supply modulator is sentenced according to this induced signal the relative position of knowing rotor unit and correspondingly sent electric current sequential.According to the operating accuracy of sensing unit and reliability requirement, can one or several sensing units be set on vehicle frame, even be deformed into from the mode of said stator unit Multiple coil feedback and use stator unit Double-wire ring around winding feedback mode obtain work-based logic transformation directive signal, now the induced signal input end 1c of power supply modulator is corresponding built-in, and its response process proposes high requirement to the logical program of power supply modulator.Due to the development of large-scale integration circuit technology, the programming technique realizing the conversion of above-mentioned work-based logic is that industry professional person is known, and institute is it is to be understood that basic design parameter such as sequential current cycle, energising subset time domain and amplitude change and therebetween break periods.
To sum up, described power supply modulator is a logic power on-off system, sequential power cycles/frequency reflects unit time internal stator unit 3a to the energization action number of times of rotor unit 3b, this time sequence frequency remote definition speed of a motor vehicle and energising amplitude required for stator unit or electromagnetic force (coming from power supply modulator to be energized to the winding of stator unit), energising amplitude is larger, unit time internal stator unit energising is larger to the application force of rotor unit, effect number of times is more, and it is faster that its result reflects the speed of a motor vehicle.The time sequence frequency of power supply modulator institute outgoing current, rotates the implicit (T of one-period with rim
1+ T
2+ T
0) sequential effect number of times, energising mean intensity and the speed of a motor vehicle be mutually corresponding all physical quantity relations, therefore after power supply modulator many imposes a condition and enter logic working state, the frequency controlling sequential energising namely controls the speed of a motor vehicle.This manual control speed of a motor vehicle is that power supply modulator can be arranged on the optional position on vehicle frame by driving the input end 1d of actuation means 9a electric connection of power supply modulator to realize.
When battery-driven car sets up electromagnetic force brake function, the corresponding brake signal input end 1e that sets up of power supply modulator is electrically connected with electromagnetic brake device 9b, as shown in Figure 5 c; Electromagnetic brake device can be set to an adjustable rheostat, and its function is the electric current controlling power supply modulator output, and intensity of current is larger, and braking effect is better.
The scheme that rotor unit 3a is fixed on rigid metal rim 6 can have multiple, such as, rotor unit is connected in inner edge or the outer rim of rim, also rotor unit can be entrenched in rim inside and carry out integrated design manufacture with rim.Stator unit arranges main points on vehicle frame, to make rotor unit with its formation, the necessary relative air gap 3d of magnetic action effectively occur in Periodic Rotating, this air gap is that stator unit transmits the energy channel of electromagnetic force to rotor unit, air gap is more little is more conducive to magnetic energy effect transmission, but the too small easy generation Mechanical Contact of air gap, needs comprehensive rigidity and the machining accuracy of holding material during design.
