The dull and stereotyped magnetic core of n block is parallel mutually to be arranged, and has gap between adjacent two pieces of dull and stereotyped magnetic cores, and brachium pontis magnetic core is connected across between the dull and stereotyped magnetic core of n block successively, spiral winding receiving coil placed in the middle in the magnetic core segmentation of the brachium pontis magnetic core between adjacent two pieces of dull and stereotyped magnetic cores.
N end of brachium pontis magnetic core is connected to the center of corresponding dull and stereotyped magnetic core.
Described brachium pontis magnetic core is made up of n vertical section and a horizontal segment, and n vertically section and a horizontal segment form n-1 the rectangular frame be connected in turn; Or described brachium pontis magnetic core is n-1 the bent frame be connected in turn.
The center distance of adjacent two pieces of dull and stereotyped magnetic cores is identical with the center distance of ambipolar wireless transmission guide rail adjacent pole.
Advantage of the present invention: the present invention and bipolar emitter guide rail with the use of, structure is simple, frivolous, high with former limit guide rail degree of coupling, not easily magnetic saturation occurs, and effective to magnetic field shielding, and Electro Magnetic Compatibility is high, can also ensure power and the efficiency of delivery of electrical energy.
The present invention and bipolar emitter guide rail with the use of time, high frequency alternating current is by the power cable of former limit guide rail, under the constraint of the two field structure guide rail in former limit, high-frequency alternating magnetic field is formed above guide rail, be positioned at receiving terminal directly over shoe and transmitting terminal forms magnetic Field Coupling, electric current is induced in receiving coil, the structural design of receiving terminal, the magnetic pole of receiving terminal magnetic core and bipolar emitter end is made to form magnetic loop, and the leakage field above reduction receiving terminal, realize the efficient wireless transmission of electric energy.
The present invention adopts brachium pontis Winding type receiving coil, and coupling coefficient between guide rail is higher; Receiving terminal bottom adopts flat plate magnet core structure designs, makes receiving terminal stronger relative to the laterally offset ability of shoe; Dull and stereotyped for bottom magnetic core is coupled together by brachium pontis by receiving terminal top, and form complete magnetic loop, can ensure that above receiving terminal, magnetic field exposure is minimum, Electro Magnetic Compatibility is good; Receiving terminal only has the connection brachium pontis of the dull and stereotyped magnetic core in bottom and top to form, and structure can be made more frivolous, save core material, reduce manufacturing cost; Receiving coil is helically coiling on connection brachium pontis, reduce the coiling difficulty of coil, and the wire of equal length can obtain larger inductance value, reduces manufacturing cost.
