Specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be defined by the claims
Implement with the multitude of different ways covering.
As shown in figure 1, the present invention discloses a kind of radio energy transmission system of electric automobile, system using inductively with
The mode of EMR electromagnetic resonance collaborative work, it comprises transmitting terminal and 2 parts of receiving terminal, and its frequency adjusts one by compensating electric capacity
Cause.Transmitter unit is embedded in below ground, and receiving unit is placed on the lower section of electric automobile, and Large Copacity high frequency electric source inputs electric energy
Launched upward by transmitter unit after relevant control circuit is by energy conversion, through 15～30cm about height air
Propagate, after receiving unit picks up energy, through energy converter, the AC energy of high frequency is changed into required for electric motor car
Electric energy.In order to reduce invalid electric energy supply during system work, the sensor sensing on each transmitter unit is close to vehicle
Afterwards, send information to Large Copacity high frequency electric source, the transmitter unit having vehicle to pass through is opened by the inverter in Large Copacity high frequency electric source
Open, the transmitter unit that vehicle passes through is started working.If vehicle moves to next section, previous transmitter unit is closed, next
Transmitter unit is started working.
Transmitting terminal structure design, transmitting terminal circuit mainly by Large Copacity high frequency electric source and with magnetic shield transmitter unit and
Relevant control circuit forms.Large Copacity high frequency electric source inputs 380v alternating current, through AC-DC-exchange conversion, exports high frequency
Signal, output can determine according to receiving terminal power and related experiment result.The sending out with magnetic shield of multiple same sizes
Penetrate unit to lay along straight line, realize the real-time power supply to electric automobile.
Receive end structure and mainly include receiving unit with magnetic shield, charging circuit and associated control element.With magnetic
The receiving unit of shielding has multiple, reception energy, and frequency is adjusted to transmitting terminal by series compensation capacitance by each receiving unit
Resonant frequency.Charging circuit then includes rectification circuit, adjusts circuit and protection circuit.During electric motor car travels, receive single
