Description
Technical field:
The utility model relates to field of batteries, and in particular, the utility model is about magnetic resonance formula wireless charging battery.
Background technology:
The wireless charging technology of mobile phone has bright development prospect.At present, abroad some enterprises have released the wireless charging mobile phone.But present battery of mobile phone structure and manufacturing process also are difficult to and the wireless charging device coupling, so that the wireless charging mobile phone that certain company of Japan makes needs external inductor support just can deal with problems, make the battery and the wireless charging device of wireless charging mobile phone be isolating construction, not only use inconvenient, and make also inconvenient, especially the big notebook computer of power consumption uses this class wireless charging device to will be referred to more technical problem.And the actual induction charging distance of existing wireless charging device is very short, and charge efficiency is extremely low.
The utility model content:
At the deficiencies in the prior art part, the purpose of this utility model provides a kind of magnetic resonance formula wireless charging battery, and not only volume is little for it, and the actual induction charging distance is far, and charge efficiency is high.
The purpose of this utility model is achieved in that the wireless charging battery that is provided is the pad pasting that is provided with induction coil and resonance coil on common batteries, induction coil on the pad pasting connects charging chip, charging chip connects battery, and the frequency of oscillation of resonance coil is close or identical with the wireless magnetic field transmitter frequency of far-end.The number of turn of induction coil and resonance coil is decided according to the number of turn of charging induction installation coil, and induction coil and resonance coil are bonded at the surface of plane pad pasting or use two layer plane pad pastings that induction coil and resonance coil are clipped between the two layer plane pad pastings.Induction coil and the coiling of resonance coil available wire or the coiling of use flat wire perhaps are plated in pad pasting surface, plane with electric plating method with induction coil and resonance coil.
When the wireless charging battery enters into the electromagnetic wave effective coverage range of less radio-frequency magnetic field transmitter, induction coil is sensed electromagnetic wave, induction coil produces electric current and gives rectification circuit and carry out rectification, rectification circuit output weak current is given the input of charging circuit respectively and is detected the input of sample circuit, charging circuit carries out trick charge to rechargeable battery, the detection sample circuit is sent weak current here to rectification circuit and is detected sampling and the vibration of control resonant circuit, drive the resonance coil vibration by the resonant circuit output current and produce alternating magnetic field, this alternating magnetic field in the certain distance scope and the alternating magnetic field that produces of the emission of magnetic field coil of less radio-frequency magnetic field transmitter resonate mutually, according to the magnetic resonance principle, the induction coil of the coil groups in magnetic induction live part induced electromotive force in mutual resonant field increases rapidly, induced current is directly given charging circuit after by the rectification circuit rectification rechargeable battery is carried out large current charge, and rechargeable battery carries out Charge Management by charging circuit.
Induction coil and resonance coil constitute with the form of pad pasting, and induction coil is magnetic core coil or air core coil.Described pad pasting is plane pad pasting or ring-type pad pasting.
The utility model has following advantage: the form with pad pasting on the magnetic resonance formula wireless charging battery is built with induction coil and resonance coil and interlock circuit thereof, induction coil connects rectification circuit, rectification circuit connects charging chip and detects sample circuit, charging chip connects rechargeable battery, detect sample circuit and connect resonant circuit, resonant circuit connects resonance coil, be provided with resonance coil in the induction coil or around the induction coil, resonance coil produces vibration with the identical or close frequency of magnetic field generator, near induction coil, produce the resonant field identical with the magnetic field generator frequency, resonate mutually in the magnetic field that two or more frequencies are close or identical in certain distance, the induction coil induced field produces electric current chargeable battery is charged.
