4 are arranged in the circulus that each magnetic stripe 3 is formed with regard to being wound around.For improving magnetic energy for emission efficiency and receiving efficiency, each circle line
Circle 4 need on each magnetic stripe 3 compact winding.
Further, the spacing of two adjacent on magnetic energy for emission coil 1 magnetic stripes 3 is adjacent with on magnetic energy receiving coil 2
The spacing of two magnetic stripes 3 is equal.Being arranged such, the energy signals that magnetic energy for emission coil 1 is converted will be more uniform, and magnetic energy connects
Energy signals received by take-up circle 2 is the most uniform.
As shown in Figure 4, Fig. 4 is the concrete structure schematic diagram of the magnetic stripe shown in Fig. 3.
About in a kind of preferred implementation of magnetic stripe 3, this magnetic stripe 3 mainly includes horizontal part 301 and is arranged on level
The projection 302 at two ends, portion 301.Wherein, horizontal part 301 is mainly used in installing each circle coil 4, and protruding 301 are then mainly used in increasing
Strong transmitting energy signals and reception energy signals.Further, the projection 302 on magnetic energy for emission coil 1 towards upwards, and magnetic energy
Projection 302 in receiving coil 2 towards downwards, so would be more advantageous in electric energy-magnetic energy and magnetic energy-electricity transformation of energy.
It addition, be energy signals emission effciency and the energy signals of magnetic energy receiving coil 2 improving magnetic energy for emission coil 1
Receiving efficiency, such as can be wound around two-layer or three layers by each circle coil 4 overlap wrapping multilamellar on the horizontal part 301 of magnetic stripe 3
Deng.And when the number of plies of coil 4 is more, for avoiding producing mutually between each layer line circle electromagnetic effect, the present embodiment is adjacent two
It is provided with insulating barrier, such as plastic plate etc. between layer line circle 4.
Additionally, the material of magnetic stripe 3 can be manganese-zinc ferrite or nickel-zinc ferrite, so, the magnetic energy letter that magnetic stripe 3 is converted
Number frequency higher, it is possible to improving energy transfer efficiency accordingly, certainly, magnetic stripe 3 can also be the materials such as soft magnetic ferrite.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
