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 two-wheel car, 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 uses common magnetic media material usually, 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 adopts permanent magnet and magnetizer two kinds of basic materials, and permanent magnet is conventional magnet steel, nd-fe-b etc., described magnetizer be known to the skilled person a kind of under magnetic fields internal state change and produce the material of backing field.

As shown in Figure 2 d, rim 6 outer rim arranges the permanent magnet rotor unit 3b1 of a S pole-face to axle 7, a stator unit 3a is arranged on the vehicle frame of rim inner edge, the N pole-face of its winding energising is to rim inner edge, relative air gap 3d is enough little in both motions, when the stator unit of permanent magnet rotor unit trend energising, can be attracted and be made wheel accelerated movement; In another embodiment, the S polar motion stator unit in opposite directions of permanent magnet rotor unit 3b1, extremely against rotation of wheel direction corresponding thereto, both magnetic action are similarly attracting to the N of stator unit winding energising, as shown in Figure 2 e.If rotor unit is magnetizer, because its year magnetic is for by stator unit electromagnetic field inducing institute extremely, no matter how the energising direction of stator unit winding is arranged, and both magnetic action are attracting, as shown in Figure 2 d; Be somebody's turn to do the electric device basic model that both attracting relations settings are the utility model battery-driven cars, it is because permanent magnet and magnetizer have and initiatively carry magnetic and by two kinds of different qualities of dynamic load magnetic that rim upper rotor part unit arranges two kinds of different substrate materials, can combine according to its different qualities variation, to adapt to the control that battery-driven car drove, braked multiple real-time status.

As shown in fig. 4 a, the electromagnetic force F that rotor unit 3b (3b1 or 3b2) trapping gap is subject to can be analyzed to normal 10 direction F ₁₀with tangent line 11 direction F ₁₁, wherein contributive around axle to rotor unit is F ₁₁, rotor unit around axle and and the determined normal of axle and stator unit and the determined normal of axle be a dynamic angle relevant to the plan of establishment of stator unit between the sphere of action of electromagnetic force suffered by rotor unit, such as single column passes through the maxim of air gap around the stator unit electromagnetism line of force of core, corresponding to the two poles of the earth line 12 and its normal 10 vertical (parallel with corresponding tangent line 11) residing for rim of electromagnetic pole, as shown in Figure 3 a; The two poles of the earth line 12 that column also can be set to electromagnetic pole around the stator unit of core overlaps with normal residing for it 10, as shown in Figure 3 b, selects when this set-up mode is generally the combination of multiple stator unit; For 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.

During rotor unit trend stator unit, it overlaps with suffered electromagnetic force F action direction around axle tangential direction is a special state, now angle for definite value the useful effect of electromagnetic force suffered by rotor unit is interval, be positioned at to be 0 state be benchmark in lane place (described ± to define according to rotation of wheel direction).When when being 0, F ₁₀for maxim, F ₁₁be 0, now complete in contribution around axle to rotor unit, as shown in Figure 4 b.F ₁₁and F ₁₀be a pair shifting kinematic variable, its theoretical strong and weak conversion with for train spacing point, rotor unit exists status and appearance is with propulsive effort F ₁₁be main, status and appearance is with braking force F ₁₀be main.

The electric device actuation techniques scheme of the utility model battery-driven car is: power supply modulator is corresponding state time domain energising, all the other time domain power-off; When design objective is for economize on electricity, preferably even corresponding time domain energising; When needs utilize vehicle wheel rotation inertia, preferably even corresponding time domain energising; Cause state is with considerable F ₁₀, state energising has lost optimization meaning to driving; The break-make time domain of this drive current as shown in Figure 6 a, wherein T ₁for current"on"time, T ₂and T ₀be power-off time, (T ₁+ T ₂+ T ₀) constitute Timing driver current cycle T.The electric device braking technology scheme of the utility model battery-driven car is: the corresponding T of power supply modulator ₂and T ₀part time domain or all time domain be set to energising, described T ₂for rotor unit is corresponding around axle time domain, described T ₀for rotor unit is away from the corresponding time domain of stator unit; In like manner, there is considerable tangential force F in state ₁₁, unhelpful to Brake Design.

Above-mentioned basis the switching electric control of state can approximate transform be that relative time controls, because be 0 state and state is aobvious state, and power supply modulator is easily sentenced by timing alignment and known from to 0, 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 electricity temporal scalable of corresponding state; Such as control corresponding extremely time domain energising, 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 corresponding to the time domain energising of 0, 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; (T ₁+ T ₂) be an amount relevant to vehicle wheel rotational speed, determine with period state there will be deviation when speed change state, 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.

After stator unit setting (comprising combination) scheme is determined, aobvious state position determined simultaneously, during actual design, normally use aobvious state position judge the one foundation of the inner relative position of electric device as sensing device; exact location 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 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 the special chip adopting large-scale integration circuit technology to manufacture realizes.

Concerning the simple analysis of a permanent magnet rotor unit and a magnetizer rotor unit on a stator unit combination rim on vehicle frame is routine, the electromagnetic force useful effect that rotor unit is not in stator unit around the axial period π most of the time is interval, first should consider T break period of electric current timing cycles T during programming ₀, and then preferred power-off time T ₂with driving T current"on"time ₁, improve the degree of utilization of electric energy, Fig. 6 b is that this simple analysis example permanent magnet rotor unit 3b1 and magnetizer rotor unit 3b2 is separated by 180 degree when being symmetrical arranged, the driving energising sequential logic schematic diagram of corresponding one of them rotor unit 3b1/3b2.Rim combines the advantage arranging bi-material rotor unit to be: if rim only arranges permanent magnet rotor unit, because its magnetic pole is fixed, in kinematic model, no matter how pole orientation arranges, all can not follow the electromagnetic force of stator unit with dynamic antipole form, to the driving of electric device, control for brake effect not as adopting the magnetizer rotor unit of induction magnetisation good; If rim only arranges magnetizer rotor unit, just because of its magnetic pole is induction magnetisation, when its be just in be in stator unit trapping gap same normal 10, when being 0, easily there is stall.Be provided with permanent magnet rotor unit 3b1 when alternate on rim, power supply modulator is sentenced by sensing device and is known be the interior location state of 0, the corresponding static state sending battery-driven car starts sequential electric current in real time; The so-called static simple example starting sequential electric current, encounter above-mentioned stall, power supply modulator when setting-up time maxim can not get sensing device feedback signal, send the starting current contrary with normal drive current direction in real time, make at least one permanent magnet rotor unit 3b1 on rim be subject to the same polarity effect of repelling each other and depart from the state being in same normal with stator unit trapping gap, avoid stall to occur.

Concerning a stator unit on vehicle frame combines the analysis case of n rotor unit (3b1/3b2) on rim, stator unit corresponding rotation of wheel cycle and n rotor unit generation electromagnetic action, power supply modulator preferably sends the energising sequential that n cycle is T, and there be n (T in the corresponding rotation of wheel cycle ₁+ T ₂+ T ₀) sequential working logic, this unitized design proposes high requirement to power supply modulator.Rotor unit not arranges The more the better, and the number n that it is arranged on rim is limited to the space occupy-place of suffered stator unit electromagnetic force useful effect, otherwise the sequential current cycle that power supply modulator correspondence exports can be overlapping.Fig. 7 a is the local structure schematic diagram that a stator unit combines 8 rotor units (3b1/3b2), stator unit wheel swing circle π respectively with 8 rotor unit generation magnetic action, power supply modulator correspondence export sequential electric current theory be divided into 8 (T ₁+ T ₂+ T ₀) cycle, Fig. 7 b denotes the T that a kind of T of setting is π/8, corresponding rim hand of rotation ₁, T ₂and T ₀schematic frequency domain, Fig. 7 c is the energising logical schematic in one of them cycle.Fig. 8 is the local structure schematic diagram of corresponding 12 rotor units of stator unit, the stator unit corresponding rotation of wheel cycle respectively with 12 rotor unit generation magnetic action.

Fig. 9 is the local structure schematic diagram of 8 rotor units (3b1/3b2) on two stator unit combination rims, and in the rotation of wheel cycle, power supply modulator will provide 8 cycles for (T for two stator unit 3a 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 and n rotor unit unitized design, if the discrete power supply of power supply modulator 1 pair 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 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, the fundamental functional modules of the latter 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 being connected in vehicle frame, conventional sensing unit uses magnetoelectric induction winding, Hall element or photoelectric encoder etc., 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 job procedure logic of power supply modulator.

To sum up, described power supply modulator is a logic power on-off system, sequential power cycles/frequency reflects the energization action number of times of unit time internal stator unit to rotor unit (3b1/3b2), 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), drive the amplitude of energising 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, 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 set 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 that controllable power modulator exports, and intensity of current is larger, and braking effect is better.
