Description
Technical field
As regenerative resource is increasingly reduced, atmosphere pollution increasingly sharpens, and country starts to widely popularize electric automobile, and pushes away
Numerous subsidy policies are gone out.However, by lithium battery that energy storage is applied has charging interval length, the drawbacks such as service life is short,
The serious development for constraining electric automobile.The appearance of dynamic radio electric energy transmission technology, can solve the above problems.The present invention relates to
A kind of dynamic radio electric power system 3 D electromagnetic coupled structure design, the formal reality that dynamic radio power supply is used with reference to electric automobile
Border is applied, and is devised a kind of with high robust, high reliability, a kind of intelligentized energy coupling structure.
Background technology
Since electricity enters the life of people, the mankind obtain electric energy, this mode by the way of wire directly contacts always
In the presence of drawbacks such as friction, abrasions, cause when needing the electric power under some such as underwater powers, colliery power complex environment,
It is not applied due to the limitation of electric energy transmission means and intrinsic drawback, this just forces people to seek a kind of new electric energy transmission
The appearance of mode.
In Chicago World's Fair of 1893, famous American physicist Nikola Tesla are passed using radio energy
Defeated principle, a lighting lamp is lighted in the case of without wire.Afterwards, various countries' researcher has proceeded by largely
Research work.
Wireless power transmission technology can be divided into stationary radio energy transmission technology and dynamic radio according to energy coupling state
Electric energy transmission technology.
By substantial amounts of theoretical research, stationary radio energy transmission technology is set in electronics such as mobile phone, notebook computers at present
The existing Related product of the field of household appliances such as standby and LCD TV, juice extractor is born.But theoretical research and technical achievement in use
Mostly based on electric energy transmitting terminal with being obtained in the case of receiving terminal geo-stationary.It is static wireless for some special occasions
Electric energy transmission generally can not meet to require.
On the basis of static wireless power transmission, it has been proposed that dynamic radio charging technique, i.e., mobile object is in motion process
The middle mode that can obtain electric energy in real time.It can solve the powerup issue in some special occasions.Such as applied to electronic
Automobile provides the supply of real-time electric energy for road surface power-supply electric vehicle in a non-contact manner, electric car is lacked carrying even without taking
Battery pack is carried, and extends course continuation mileage.As can be seen here, electric automobile has many benefits using dynamic radio power supply technique.
However, during wireless power transmission, because Road Factor causes rocking for automobile, electric automobile energy coupling mechanism occurs
Vibration, power supply quality decline, it is impossible to meet the power demands of electric automobile.
The content of the invention
The technical problems to be solved by the invention are, it is proposed that a kind of dynamic radio electric power system 3 D electromagnetic coupled structure
Design, the structure design can reduce because Road Factor causes rocking for automobile, and electric automobile energy coupling mechanism shakes
Dynamic, power supply quality declines, it is impossible to the problem of meeting the power demands of electric automobile, make electric automobile power supply with high robust,
High reliability, intelligentized feature.
The technical solution adopted in the present invention is：A kind of dynamic radio electric power system 3 D electromagnetic coupled structure design, bag
Energy emission system and energy acceptance system two parts are included, high-frequency electrical energy is transformed into magnetic energy, energy by energy emission system
Reception system receives magnetic energy and is converted into electric flux, and power supply electrical automobile uses.
Described energy emission system is formed by connecting by multiple transmitter units in the form of in parallel, each transmitter unit by
Multiturn strand copper wire is entwined.When electric automobile is powered using dynamic radio, energy emission system is laid on above road.
Described energy acceptance system is formed in parallel by three receiving coils, and each receiving coil is twined by how miscellaneous strand copper wire
Around into.This structure can be improved in electric automobile dynamic radio power supply process, the receiving power and efficiency of system.
The present invention a kind of dynamic radio electric power system 3 D electromagnetic coupled structure design, the device have high robust,
High reliability, intelligentized feature.After system energization works, energy emission system can be opened automatically according to the position of electric automobile
Open or close, energy acceptance system can need in efficient operation, guarantee electric automobile power supply under vibration.
