Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
See Fig. 1, the present invention is made up of electronlmobil, rectifier bridge and the storage battery after source of AC, the metal track being embedded in underground, additional circuit, repacking.Concrete structure comprises the charging network in the metal wheel hub 1 of electronlmobil, the two strip metal tracks 2 being layed in underground and electronlmobil; Two strip metal tracks 2 are connected with external ac power source, and connect inductance L on metal track 2, realize LC resonance for the electric capacity formed between two strip metal guide rails 2; The metal wheel hub 1 of electronlmobil both sides is insulated by the insulated connecting piece 4 being arranged on axletree two ends, and metal wheel hub 1 forms electric capacity by tire 5 and metal track 2; Metal wheel hub 1 is provided with the brush for drawing electric energy, brush and metal wheel hub 1 close contact; Electric network comprises rectifier bridge and storage battery, and the brush on the input end difference connecting electric automobile both sides metal wheel hub of rectifier bridge, the mouth of rectifier bridge is connected to the two ends of storage battery.Brush on the metal wheel hub of electronlmobil homonymy is connected on the same input end of charging network; Two electric capacity that the metal wheel hub of electronlmobil homonymy and metal guide rail are formed are in parallel.The two bottom sides of Rechargeable vehicle is also provided with sole plate metal 3, forms electric capacity and the electric capacity that formed between metal wheel hub 1 and metal guide rail 1 is in parallel between sole plate metal 3 and metal guide rail 1.Electric capacity is there is between bottom of car sole plate metal 3, between coaxial metal wheel hub 1.
The present invention is based on the wireless power transmission technology of field coupling, the schematic diagram that electronlmobil field is applied as shown in Figure 2, is realized by following principle:
1) by repacking to electronlmobil, define six electric capacity, comprise formed between metal wheel hub with track four electric capacity, bottom of car two electric capacity being formed with corresponding guide rail respectively of sole plate metal.Make three Capacitance parallel connections of automobile the same side, track left and right sides forms an equivalent capacity C with vehicle right and left side respectively
0;
2) electric capacity C is formed between the metal track being embedded in underground
1, metal guide rail and electronlmobil entirety can be equivalent to an electric capacity two-port network;
3) there is electric capacity between bottom of car sole plate metal, between coaxial wheel hub, in parallel with rectifier bridge input end, be equivalent to C in circuit
2.
4) storage battery is equivalent to an electric capacity C
3, because alternating current becomes direct current (DC) through rectification, after connect electric capacity and can be considered open circuit, do not consider the impact of charging network on front network.Storage battery equivalent capacity is connected on the mouth of above-mentioned electric capacity two-port network, and Two-port netwerk input end can be equivalent to total capacitance C.
5) between power supply and metal track, access additional circuit makes the power of mouth maximum.Suppose that power supply is voltage source, when the input impedance entered viewed from power supply is minimum, horsepower input is maximum.Owing to being passive element in equivalent circuit, can think that after ignoring loss horsepower output is approximately equal to horsepower input, therefore the most one hour rated output of impedance is maximum;
6) additional circuit is inductance L, when parameter meets ω
2during LC=1, reach series resonance state, input resistance is minimum.
To the refiting scheme of electronlmobil, specifically comprise the following steps:
1) between automotive hub and axletree, add dielectric, block the electrical communication between vehicle right and left two wheel hubs, electronlmobil tire part defines four independently electric capacity;
2) be mounted on the brush in car at each metal wheel hub place, and make wheel hub and brush close contact, the electric current being passed to wheel hub by electric capacity can be drawn by brush;
3) on generation automotive underbody, install two pieces of sole plate metal of separating, installation form is identical with ground substrate track installation form, forms electric capacity respectively with corresponding track;
4) automobile has formed six electric capacity.The sole plate metal of corresponding for the front and back wheel being positioned at automobile the same side brush, bottom is connected by wire, makes three Capacitance parallel connections of the same side, and draw wire and power to the load.The left and right sides is all like this, constitutes two groups of electric capacity;
5) wire that the left and right sides is drawn is connected to the input end of rectifier bridge, and alternating current is converted to direct current (DC) by rectifier bridge, exports to storage battery power supply.
The present invention is based on the movement-static Campatible electronlmobil of wireless power transmission, be not confined to the magnetic Field Coupling thinking of wireless charging routine, but take new mode to realize wireless charging, achieve normal charge mode and be difficult to wireless charging in the movement realized.This charging modes can realize through motor tire, base Wireless power transmission in movement, and realizes wireless charging quickly and efficiently in the mode of resonance; This can be applied on express highway and average highway through rail wireless charging technology, can avoid long charging wait time; Meanwhile, avoid heavy coil is installed in car, little to car transformation requisite space.Adopt wireless charging electronlmobil of the present invention especially can be used in the underdeveloped area of charging network, avoid conventional electronlmobil heavy and the storage battery of costliness, and during discharge and recharge, there is less degradation of energy.Because the parameter request such as structure, position of mode to coil of routine is very high, the coil matched must be in a certain fixing relative position, and this causes this mode not to be suitable for electronlmobil charging under steam, and must static charging.The electronlmobil of this employing novel radio charging technique then can effectively realize automobile and charge under steam.
The present invention utilizes electric impedance analyzer to record interorbital electric capacity, improved six electric capacity of electronlmobil, is calculated the equivalent capacitance value of storage battery, can obtain the partial parameters of Fig. 2 by the parameter of storage battery.According to the producible signal frequency range of power supply, choose reasonable inductance parameters, makes to meet ω
2lC=1.Power supply is received metal track two ends to power, measure the variable quantity of battery tension in certain hour.Charge efficiency is weighed with the electricity charged a battery in the unit time.
Charge model parameter according to building carries out circuit simulation, wherein L=527uH, C0=19.0pF, C1=9pF, C2=10pF.As shown in Figure 3 and Figure 4, when power frequency is 1.88Mhz, rectifier bridge front end input voltage reaches peak value to simulation result, and input impedance reaches minimum value.Show that the resonant frequency of system is 1.86Mhz by theory calculate, the two is comparatively identical.Illustrative system really when reaching LC resonance charging effect best.
Above content is only and technological thought of the present invention is described; protection scope of the present invention can not be limited with this; every technological thought proposed according to the present invention, any change that technical scheme basis is done, within the protection domain all falling into claims of the present invention.
