Description
Technical field
The invention belongs to electromagnetic equipment field, enhances coupling device more particularly, to a kind of hollow coil
Background technique
Wireless power transmission is a kind of using electromagnetic induction phenomenon, carries out the technology transmitted every empty electric energy.That is alternating current
It can produce the magnetic field of alternation, alternating magnetic field also can produce the electric field of alternation, and electromagnetic field is propagated in the sky, in friendship
Conductor in Electromagnetic Field can produce the electric current of alternation.It is all to drive that people can use the alternating current generated in the conductor
Such as mobile phone, light bulb, water heater, TV electrical equipment.
As shown in Figure 1, single layer coil is exactly with insulation currently, electromagnetic coupling transmitting assembly largely uses single layer coil
The circle of conducting wire one is wound on paper tube or bakelite skeleton with suffering a circle.It in fact, is exactly only one to enclose one in the horizontal direction with single line circle
The coiling of circle forms, and is then put into assembly;However, the phenomenon that part leakage magnetic field can be generated using this coil, to lead
Cause the overall technology parameter of entire coupler low.
Summary of the invention
In view of this, the invention is directed to a kind of structurally reasonable, the hollow line of raising Crank-Angle number of electric varying magnetic field friendship
Circle enhancing coupling device.
In order to achieve the above objectives, the technical solution of the invention is achieved in that
A kind of hollow coil enhances coupling device, including substrate, side wall, interior surrounding edge, external inductance coil, interior inductance coil and
Neutral gear, for the substrate-side along side wall is extended upward, the inside sidewalls closely connect external inductance coil, the dispatch from foreign news agency
It is separated with neutral gear between sense coil and interior inductance coil, interior inductance coil is closely surround with interior surrounding edge.
Further, magnetic masking layer is equipped on the inside of the side wall and interior surrounding edge.
Further, the side of the substrate is equipped with march-past capacitor, the capacitor respectively with external inductance coil and interior
Inductance coil connection.
Further, the external inductance wire circle is no less than 4 circles, and interior inductance coil circle number is no less than 6 circles.
Compared with the existing technology, a kind of enhancing of hollow coil described in the invention coupling device has the advantage that
The invention is structurally reasonable, and coupling effect is good, and using " returning " shape multi-layer compound structure, two sections of independent coils are set
Meter, improved coupler shell are formed the gap that step closes horizontal direction by inside and outside surrounding edge, enable the cavity of coupler
The leakage of signal is entirely prevented, furthermore the neutral gear enhances central magnetic field effect, so that it is played optimal resonance effect, greatly
Amplitude reduces the loss of signal, considerably increases the stability of product, is integrally improved the performance of product.
