Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
As shown in Figure 1, Fig. 1 is the embodiment of the present application structural representation, the application provides a kind of transducing head of electric automobile wireless charging, the charging device of electric automobile is divided into vehicle end and non-vehicle end, carrying out in wireless charging process to electric automobile, need to arrange at vehicle end and non-vehicle end the transducing head changed electric energy and magnetic energy respectively, be used for the magnetic energy received to be converted to electric energy at the transducing head of vehicle end, be used for the electric energy from power plant or power supply unit to be converted to magnetic energy at the transducing head of non-vehicle end.The transducing head of a kind of electric automobile wireless charging of the application comprises transducing coil 1, resonant capacitance 3 and antifreeze plate 2.Resonant capacitance 3 is in parallel with transducing coil 1.Transducing coil 1 is formed by wire spiral winding, and in particular, transducing coil 1 is entwined at same plane inside spin by wire, and the diameter of transducing coil 1 sets according to power.Fig. 2 is the embodiment of the present application wire spiral winding schematic diagram, transducing coil 1 by a wire in same plane from inner ring spiral winding to outer ring, form transducing coil 1.
Transducing coil is used for carrying out the mutual conversion of electric energy and magnetic energy in electric automobile wireless charging process, transducing coil from another transducing coil received energy, or from energy storage equipment received energy.Above-mentioned transducing coil, from energy storage equipment received energy, is specially: transducing coil is from the power storage cell received energy of electric automobile and be transmitted into another receiving system, completes power conversion.Fig. 3 is the transducing head installation site schematic diagram of a kind of electric automobile wireless charging of the application, as shown in Figure 3, when transducing head is used for vehicle end, under transducing coil 1 is generally installed on the chassis of electric automobile, and called after receiving coil; When transducing head is used for non-vehicle end, transducing coil 1 is generally placed in above charging host movement 4, called after transmitting coil.Receiving coil can from transmitting coil received energy, also can from the power storage cell received energy of electric automobile.
From the electric energy that power plant or power supply enterprise obtain, after the power driving circuit of charging host movement 4, be sent to the transducing coil 1 of non-vehicle end, due to can magnetic field be produced around electrical conductor, therefore after transmitting coil energising, convert electrical signals to magnetic signal; According to electromagnetic induction principle, when the magnetic flux in closed conductor changes, conductor will produce induced current, utilize this principle, the magnetic signal received is changed in order to the signal of telecommunication by receiving coil, has induced current to flow through in receiving coil.The magnetic flux density of faradic size and transmitting coil and the distance dependent between transmitting coil and receiving coil in receiving coil, the magnetic flux density of transmitting coil is stronger, distance between transmitting coil and receiving coil is nearer, and the induced current produced in receiving coil is stronger.Fig. 4 is transmitting coil and receiving coil operating state equivalent circuit diagram, as shown in Figure 4, and R
ofor transmitting terminal loop equivalent resistance, L1 is transmitting coil equivalent inductance, and K is circuit switching, U
ifor input signal source, L2 is receiving coil equivalent inductance, and C is resonant capacitance, R
lfor load resistance, U
ofor output voltage.When circuit switching K closes, U
ithere is provided electric current I i to transmitting terminal loop, according to electromagnetic induction principle, in receiving terminal L2, induced current and induced voltage can be produced.Receiving terminal L2 and C forms antiresonant circuit, works as U
iwhen the signal frequency fi of input equals the natural frequency f0 of antiresonant circuit, L2 and C produces parallel resonance, namely
time, receiving terminal L2 and C produces parallel resonance.According to the feature of parallel resonance, set the parameter of L2 and C, can obtain desirable Q value, now receiving terminal can obtain Q Ii doubly, if Ii is 1A, Q is 10, the obtainable electric current I o of receiving terminal is Q × Ii=10 × 1=10A.Parallel resonance is also called current resonance, and the resonant capacitance of receiving terminal serves power back-off effect.
When carrying out the wireless charging of electric automobile, if operating frequency is 20kHz, charge power is about 20 ~ 30kw, between transmitting coil and receiving coil, magnetic field intensity is comparatively strong, if do not shield magnetic circuit, magnetic field can produce magnetic interference to the instrument on electric automobile at vehicle end, electromagnetic radiation is caused to vehicle driver, when serious, eddy current can be formed on the chassis of electric automobile, cause chassis to generate heat burning of even vehicle; Magnetic field can produce magnetic interference to the charging host movement 4 of wireless charging device at non-vehicle end, reduces its operating efficiency, therefore on the magnetic circuit not needing magnetic field to pass through, carries out shielding to disturbing magnetic field and is very important.
When field frequency is lower than 100kHz, the shielding measure in magnetic field mainly depends on the magnet short-cut path effect that high-permeability material plays, and utilizes the high magnetic permeability characteristic of Ferrite Material to carry out magnetic field short circuit to disturbing magnetic field.Electric field has power line, and there is the magnetic line of force in magnetic field, and the path that the magnetic line of force passes through is called magnetic circuit, and magnetic circuit & circuit has similar feature.Magnetic circuit has magnetic resistance, and magnetic resistance is relevant with the length of magnetic circuit, the sectional area of magnetic circuit and relative permeability.Relative permeability refers to this of the magnetic permeability of metal and the magnetic permeability of air.Magnetic permeability is larger, and magnetic resistance is less, and magnetic flux mainly selects the material by high magnetic permeability.If there is the magnetic field path of high magnetic permeability in magnetic field, then magnetic flux is just greatly reduced by the part of surrounding air relatively, and the magnetic interference of surrounding air is also greatly reduced simultaneously, and Fig. 7 is transmitting coil and receiving coil magnetic line of force schematic diagram; Fig. 8 is transmitting coil and the receiving coil magnetic line of force schematic diagram with antifreeze plate 2; As shown in Figure 8, when arranging antifreeze plate 2 respectively to transmitting coil and receiving coil, there is refraction and change magnetic circuit in the magnetic line of force, namely the magnetic line of force cannot pass through antifreeze plate 2 and treats shielding device and cause magnetic interference, thus treats the effect that shielding device serves magnetic field shielding in antifreeze plate 2.Specifically, as shown in Figure 3, in the present embodiment, adopting antifreeze plate 2 to be placed between transmitting coil and charging host movement 4, for carrying out, magnetic field shielding being carried out to charging host movement 4; Adopting antifreeze plate 2 to be placed between receiving coil and electric automobile chassis, for carrying out, magnetic field shielding being carried out to electric automobile.The structure of above-mentioned charging host movement 4 is set forth in the patent application document of 201410856362.0 at application number, repeats no more herein.
When high-frequency current passes through in the conductor, along with the distance with conductive surface increases gradually, the current density in conductor is exponentially successively decreased, and the electric current namely in conductor is concentrated in the surface of conductor.From the cross section vertical with electric current, the core current strength of conductor is zero substantially, does not namely almost have electric current to flow through, only has electric current in the part of conductor edge.Be exactly the parts of skin of current convergence at conductor briefly, so be referred to as kelvin effect.The electromagnetic field that the reason producing this effect mainly changes creates eddy electric field at conductor, offsets with original electric current.If obviously only use in frequency applications a wire because of its surface area relatively little, so current utilization rate will reduce greatly, and the serious or signal attenuation of conductor overheating is increased, and this is obviously that we are undesirable.Alleviating one of the simplest method of kelvin effect is exactly adopt stranded conductor parallel connection to use, the magnetic field that electric current is produced this comparatively evenly, generally provide more large-area " skin " path to electric current exactly.Power is identical and volume is identical when, this adopts the caloric value of sub-thread enamelled wire 111 much smaller to adopt multiply enamelled wire 111.In the present embodiment, wire comprises the core 11 that more than two strands or two strands enamelled wires 111 are formed in parallel, and is covered in the insulating barrier 12 outside core 11; Enamelled wire 111 is copper cash enamelled wire, aluminum steel enamelled wire or alloy enamelled wire.In the present embodiment, select diameter to be the circular copper cash enamelled wire 111 of 0.1mm, then its sectional area is about 0.007854mm
2d.C. resistance is about 2237 Ω/km, the radical of the enamelled wire 111 comprised in wire can calculate according to actual current, as, the safe carrying capacity of 25 square millimeters of copper power lines is 120A, if transducing coil 1 maximum current is in the course of the work 120A, then the quantity of circular copper cash enamelled wire 111 is needed to be: 25 ÷ 0.007854 ≈ 3183 (root).In actual applications, usually get the current margin of a times, namely if desired safe carrying capacity is 120A, then adopt about 7000 circular copper cash enamelled wires.
As shown in Figure 9, above-mentioned wire comprises the insulating barrier 12 be covered in outside core 11, and the insulating material that this insulating barrier 12 is formed by rubber or plastics is made, and has waterproof, insulation and high voltage withstanding effect.
The magnetic induction line distribution of energization solenoid as shown in Figure 5, according to right-hand screw rule, magnetic induction line is by the closed curve of N pole to S pole, and the relation of magnetic induction line direction and the sense of current can judge by Ampere's law, change sense of current, the direction of magnetic induction line changes thereupon.Magnetic induction line is straight line in energising helix tube inside, and outside is closed curve.Fig. 6 is hot-wire coil magnetic induction line distribution schematic diagram, hot-wire coil magnetic induction line is the closed curve around toroidal conductor, on the central shaft of toroidal conductor, magnetic induction line and toroidal conductor plane orthogonal, relation on the direction of ring current and central shaft between magnetic induction line direction can judge by Ampere's law, change the direction of ring current, the direction of magnetic induction line changes thereupon.When inputting alternating current in hot-wire coil, can obtain the magnetic induction line of alternation, namely can obtain the magnetic field changed between N, S pole of hot-wire coil, and the magnetic flux density of hot-wire coil is relevant with ring current size, electric current is larger, and magnetic flux density is larger.If the diameter of hot-wire coil is AB, o is the center of circle of hot-wire coil, r is the radius of hot-wire coil, magnetic induction line due to hot-wire coil is the closed curve from N pole to S pole, and on the central shaft of toroidal conductor, magnetic induction line and toroidal conductor plane orthogonal, thus the length of magnetic induction line the shortest be r; R is longer, and magnetic induction line is longer, and the magnetic induction line between N pole and S pole is higher, and the magnetic flux density between hot-wire coil upper and lower N, S pole is stronger; Namely in hot-wire coil, the diameter of hot-wire coil is larger, and magnetic flux density is longer, and between hot-wire coil upper and lower N, S pole, magnetic flux density is stronger, and transmission range is far away.Magnetic induction density B=μ ni that energising drum produces, wherein μ is constant, and n is the energising drum coil number of turn, and i is current strength in energising drum.Transducing coil 1 is entwined at same plane inside spin by wire, and the number of turn that wire is wound around is more, then the diameter of transducing coil 1 is larger, and therefore in this application, the diameter of transducing coil 1 is larger, and the magnetic flux density produced in the energized state is stronger.In the present embodiment, the diameter of transducing coil 1 sets according to power, and power is larger, and the diameter of transducing coil 1 is larger, and in the present embodiment, the diameter of transducing coil 1 is 20 ~ 180cm.In other embodiments, the diameter of transducing coil 1 is 90cm.
The application provides a kind of transducing head of electric automobile wireless charging, comprises transducing coil 1, resonant capacitance 3 and antifreeze plate 2, and transducing coil 1 two ends parallel resonance electric capacity 3 forms antiresonant circuit, reaches the effect of power back-off; Transducing coil 1 adopts multiply enamelled wire 111 spiral winding to form, and can alleviate kelvin effect, improves the utilance of electric current; The insulating barrier 12 be covered in outside core 11 has waterproof, high voltage bearing effect; Antifreeze plate 2 is placed between transducing coil 1 and equipment to be shielded, can treat shielding device and carry out magnetic field shielding; This transducing head is used for carrying out the conversion of electric energy and magnetic energy in electric automobile wireless charging process, and transducing head can from another transducing head received energy, or from energy storage equipment received energy.Therefore this application provides that a kind of power resource utilance is high, the transducing head of the electric automobile wireless charging of waterproof, high voltage withstanding, anti-electromagnetic-radiation.
