Summary of the invention
For the problem in above-mentioned background technology, the utility model provides the low automobile wireless charging device of a kind of alignment sensitivity.
The automobile wireless charging device that a kind of alignment sensitivity is low comprises stiff end and mobile terminal, described stiff end comprises former limit electrical energy changer and former limit Energy Transfer coil, described former limit electrical energy changer comprises rectification and power factor correction circuit, inverter circuit, rectification and power factor correction circuit are connected with electrical network, and rectification and power factor correction circuit, inverter circuit are connected in turn with former limit Energy Transfer coil, described mobile terminal comprises secondary electrical energy changer and secondary Energy Transfer coil, described secondary electrical energy changer comprises rectification and power factor correction circuit and DC transfer circuit, DC transfer circuit is connected with battery, secondary Energy Transfer coil, rectification and power factor correction circuit, DC transfer circuit is connected in turn, the iron core that former limit Energy Transfer coil comprises two connected subcoils and is placed on two subcoils, the magnetic field of two subcoil generations is strengthened mutually, one end of described iron core connects with the inner ring of a subcoil, the other end connects with the inner ring of another subcoil, and make described iron core cover the inner ring of two subcoils, described former limit Energy Transfer coil is identical with secondary Energy Transfer loop construction.
When wireless charging device works, the spacing between former limit Energy Transfer coil and secondary Energy Transfer coil is 15cm.
The area coil of described former limit Energy Transfer coil or two subcoils of secondary Energy Transfer coil is 500mm*500mm.
The iron core of described secondary Energy Transfer coil is positioned at the below of two subcoils.
Whole device, owing to being placed in underground and chassis, can not take additional floor space, eliminates the trouble of artificial plug charging plug simultaneously, electric motor car is charged and becomes convenient.The special construction of coil makes at car not completely to still ensureing good Energy Transfer on time, and car owner's stopping for charging need not be aimed at completely, brings conveniently to wireless charging.

Embodiment
Be described further below in conjunction with embodiment and accompanying drawing thereof.
As Figure 1-4, the automobile wireless charging device that a kind of alignment sensitivity is low comprises stiff end and mobile terminal, described stiff end comprises former limit electrical energy changer 4 and former limit Energy Transfer coil 3, described former limit electrical energy changer comprises rectification and power factor correction circuit, inverter circuit, rectification and power factor correction circuit are connected with electrical network, and rectification and power factor correction circuit, inverter circuit are connected in turn with former limit Energy Transfer coil, described mobile terminal comprises secondary electrical energy changer 1 and secondary Energy Transfer coil 2, described secondary electrical energy changer comprises rectification and power factor correction circuit and DC transfer circuit, DC transfer circuit is connected with battery, secondary Energy Transfer coil, rectification and power factor correction circuit, DC transfer circuit is connected in turn, the manganese-zinc ferrite iron core 6 that former limit Energy Transfer coil comprises two connected subcoils and is placed on two subcoils, the magnetic field of two subcoil generations is strengthened mutually, one end of described iron core connects with the inner ring of a subcoil, the other end connects with the inner ring of another subcoil, and make described iron core cover the inner ring of two subcoils, described former limit Energy Transfer coil is identical with secondary Energy Transfer loop construction.
The optional litz wire coil 5 of described subcoil; When wireless charging device works, the spacing between former limit Energy Transfer coil and secondary Energy Transfer coil is 15cm.The area coil of described former limit Energy Transfer coil or two subcoils of secondary Energy Transfer coil is 500mm*500mm.The iron core of described secondary Energy Transfer coil is positioned at the below of two subcoils.
Former limit electrical energy changer is embedded in underground, from electrical network power taking, by former limit electrical energy changer, reaches rectification, power factor correction, high-frequency inversion and the function with coil resonance, makes ground coil export high frequency magnetic field; Secondary coil and electrical energy devices are placed on electric vehicle chassis, and induction of high frequency magnetic field obtains energy, produce electric energy by secondary electrical energy changer, carry out rectification and transformation of electrical energy function successively, charge to load battery.The induction coil of current most of wireless charging device is when producing horizontal-shift, its coupling coefficient can reduce greatly, thus make namely to make the generation of wireless charging power decline to a great extent when car owner's parking spot produces skew a little, make charging interval rising, decrease in efficiency, deviated from wireless charging and brought original idea easily.The utility model employs coil and the iron core of special construction, coil is " day " font structure, middle magnetic core is distributed in coil inner circumferential, its length is just mutually concordant with the interior turn coil, higher coupling coefficient can be reached with less weight, and can when there is certain deviation in electric vehicle chassis coupling coefficient still higher, thus ensure that its good charging ability.
