Abstract
In the utility model, a sympathetic vibration derivative ring is an LC harmonic vibration loop located between an emitting coil and a receiving coil for transferring energy in electromagnetic sympathetic vibration. The sympathetic vibration derivative ring is formed by connecting an annular coil L and a non-polar capacitor C in series. The sympathetic vibration derivative ring, the emitting coil and the receiving coil work in a harmonic vibration state with the same frequency simultaneously (that is, sympathetic vibration); when the emitting coil works, the sympathetic vibration derivative ring receives the energy from the emitting coil to generate the harmonic vibration, form the secondary emission of the energy and transfer the energy to the receiving coil, so that the directional wireless transmission of the energy and the gradient distribution of the energy are realized.
Description
Technical field
The present invention is a kind of in electromagentic resonance, and the LC resonant ring that is used for energy delivery between transmitting coil and receiving coil is referred to as the ring of deriving that resonates.
Background technology
Electromagentic resonance is immensely popular in recent years wireless power notion, magnetic energy transmission by electromagentic resonance, energy has been realized contactless transmission between transmitting coil and receiving coil, the energy delivery of this " mystery " will make a lot of electric equipments take off " tail ".In September, 2010, international wireless charging alliance (Wireless Power Consortium) has issued the industrial standard of first wireless charging, make this energy delivery pattern expose in the world with legal identity, formally opened the gate in wireless power epoch in for many years worry and arguement back.
Existing wireless power, be that electromagentic resonance is realized on principle, promptly transmitting coil and receiving coil all work in the resonance condition of same frequency, and three kinds of modes are arranged aspect hardware interface usually, a kind of is mode one to one, and promptly a transmitting coil is given a receiving coil power supply; Another kind is the many-one mode, and promptly a plurality of transmitting coils are given a receiving coil power supply simultaneously, and also a kind of is one-to-many manner, and promptly a transmitting coil is given a plurality of receiving coil power supplies simultaneously.Any interface mode no matter, transmission range is all very limited, has only several centimetres or tens of centimetres usually, and direction is that fix, single, and this is the characteristic decision in magnetic field.But in actual life, usually need long distance or relative broad range and energy field that have Gradient distribution, such as, may put display, audio amplifier, desk lamp, keyboard and mouse etc. on the desk tops, the power consumption of these electrical appliances is different, when the mode with wireless power provides electric energy to them, just can not be with an emission source, and will power respectively to them with a plurality of emission sources, this just may cause following many-sided problem: interference and compatibling problem, radiation and health problem, cost problem, efficiency problem etc.
The energy of an emission source can be come distribute energy according to different directions and gradient, thereby solve above-mentioned problems? answer is sure, and resonating derives encircles is feasible solution.
Summary of the invention
The present invention is a kind of in electromagentic resonance, the LC resonant ring that is used for energy delivery between transmitting coil and receiving coil, be referred to as the ring of deriving that resonates, it is in series by a loop coil L and a polarity free capacitor C, the two ends that are coil link to each other with two electrodes of electric capacity respectively, the resonance frequency of this series loop is identical with the operating frequency of transmitting coil (being tranmitting frequency), also identical with the resonance frequency (being receive frequency) of receiving coil, like this, transmitting coil, derive ring and receiving coil of resonance works in the resonance condition (promptly resonate) of same frequency simultaneously.When transmitting coil was worked, the resonance articulating of deriving was received energy from transmitting coil, produces resonance, forms the Secondary Emission of energy, gives receiving coil with energy delivery, realizes the wireless transmission of energy.
The effect of ring because resonance is derived, following three variations will take place the transmittance process of energy: 1, the distance of energy delivery strengthens; 2, the direction of energy delivery owing to transmitting coil, resonance derive the ring change different with the locus of receiving coil; 3, the derive quality of ring of the density of energy delivery and resonance is relevant, can realize the Gradient distribution of energy by changing the derive quality of ring of resonance.
The derive spatial relation of ring and transmitting coil, receiving coil of resonance: electromagentic resonance mainly transmits energy by magnetic field, because magnetic field has very strong directivity, and the biquadratic of energy density and distance is inversely proportional to, therefore, the transmission of energy distance is very limited in the electromagentic resonance, the difference of Energy distribution in different directions also is fairly obvious, and is usually, the strongest in the normal direction Energy distribution of coil plane.The derive locus of ring, transmitting coil and receiving coil of resonance, the energy delivery direction and the energy density of electromagentic resonance will directly be changed, spatial relation between the three has following several: 1, transmitting coil, resonance are derived ring and receiving coil in same normal direction, and promptly three coils are parallel up and down.2, transmitting coil, resonance are derived ring in same normal direction, and two coils are parallel up and down, and receiving coil and resonance are derived ring at grade, and is contiguous or overlapping.3, transmitting coil, resonance are derived ring at grade, and is contiguous or overlapping, and receiving coil and resonance are derived ring in same normal direction, and two coils are parallel up and down.
The derive quantitative relation of ring and transmitting coil and receiving coil of resonance: the energy of a transmitting coil can pass to a resonance and derive to encircle and pass to a receiving coil again; The energy of a transmitting coil also can pass to a plurality of resonance ring of deriving and pass to a plurality of receiving coils again.
The derive relation of quality of ring of the Gradient distribution of energy and resonance: from the energy of transmitting coil is to pass to receiving coil by the derive Secondary Emission of ring of resonance, and therefore, the derive quality of ring of resonance directly has influence on energy distributions density.The quality serviceable item quality factor of coil is weighed, and promptly Q is a quality factor in the Q=2 π fL/R formula, and f is a resonance frequency, and L is the derive inductance value of coil of ring of resonance, and R is the resistance of the coil of the ring of deriving for resonance.The Q value is big more, and the quality of coil is high more, and the ability of Secondary Emission is strong more, otherwise weak more.R is relevant with size with material, the shape of coil.
The coil shape that resonance is derived and encircled: receiving coil is derived to encircle from resonance and is obtained energy, therefore, the shape of the coil that resonating derives encircles has just determined receiving coil to obtain the scope of energy, that is to say the scope of application of the electrical appliance that has determined the receiving coil place, on the contrary, the scope of application of electrical appliance with resonance derive the ring coil be the border, usually, resonance derive the ring coil shape can be circle, oval, triangle, quadrangle, polygon, irregular annular, spring-like etc., though shape differs, all form around (containing enamelled wire) system by one or one group of stranded conductor, the two ends of coil last with a capacitances in series.
Beneficial effect of the present invention: resonance is derived and is encircled the direction of transfer that not only can change the energy of electromagentic resonance, can also need realize the Gradient distribution of energy according to the power consumption of electrical appliance, thereby realize the rational wireless power of an energy emission source to a plurality of electrical appliances, made full use of the energy, improved efficiency, reduced radiation and loss, be convenient to management simultaneously, provided cost savings (resonance derive the cost of ring have only some/one of the cost of an emission source).
