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, and n the end that brachium pontis magnetic core is connected across on the dull and stereotyped magnetic core of n block is wound around receiving coil;
Receiving coil intersects coiling successively at a described n end.
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 utility model: energy acceptance end described in the utility model and bipolar emitter guide rail with the use of, after considering the Distribution of Magnetic Field that bipolar emitter guide rail produces, design brachium pontis intersection Winding type dull and stereotyped magnetic core receiving terminal mechanism, it and bipolar emitter rail unit form wireless power transmission structure.This receiving terminal 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 ensure power and the efficiency of delivery of electrical energy, and then ensures power supplying efficiency.
The receiving coil of receiving terminal described in the utility model adopts brachium pontis to intersect Winding type structure, and coupling coefficient between guide rail is higher; The flat plate magnet cored structure of receiving terminal bottom, makes receiving terminal stronger relative to the laterally offset ability of shoe.Adjacent two pieces of dull and stereotyped magnetic cores are coupled together by brachium pontis magnetic core, form complete magnetic loop, and 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 is more frivolous, saves core material, reduces manufacturing cost.The coiling of receiving coil intersection, reduce the coiling difficulty of coil, and the wire of equal length can obtain larger inductance value, reduces manufacturing cost.
