Abstract
The invention discloses a high-performance wireless charging device. In order to overcome the shortcomings such as large magnetic loss of electromagnetic space, large coil size, high material consumption, low production efficiency and high cost of an existing wireless charging device, the cross section of a winding material of a coil of the high-performance wireless charging device is in a shape of non-circular rectangle or square; since winds wound by the winding material are positioned on a same plane and of consistent interval specifications, each coil winding is a coiled body comprising a plurality of flat sheet-like winds which are positioned on the same plane and of consistent interval specifications, and the coil winding can be integrally formed. The high-performance wireless charging device is mainly applied to wireless charging in the field of electric vehicles and intelligent mobile phones. Experiment shows that the space magnetic loss rate of the high-performance wireless charging device is decreased by 85%, the receiving and transmitting efficiency is improved by 20%, and defective ACR can be avoided; and the coil is small in size, occupies small space, can be formed by using a mold without manual or mechanical winding, and is low in material consumption, high in production efficiency and low in production costs, thereby significantly improving the benefit.
Description
Technical field
The present invention relates to a kind of be mainly used in electric automobile, device that smart mobile phone field utilizes electromagnetic induction principle to carry out wireless charging, be specially a kind of high-performance wireless charging device.
Background technology
Wireless charging device utilizes Wireless charging coil (transmitting coil TX) electromagnetic induction to be charged, for the field such as electric automobile, smart mobile phone.
Wireless charging is accomplished that secondary energy sources are changed, and will net after electricity blood pressure lowering (or directly) becomes unidirectional current, then carry out the on-off control exchange exchange output of a upper frequency.
The deficiency of existing wireless charging device, one is that the conversion of high-power friendship orthogonal electric current carries out secondary and is wirelessly transferred, and the space magnetic loss rate of electromagnetism is big；Two is the coil employing self-adhesive enameled wire coiling of existing wireless charging device, and winding volume is big, takes up room big, and magnetic loss rate is big, and copper loss is higher, and height is lost accordingly；Three is that the coil of existing wireless charging device needs to make of special self-adhesive enameled wire and production equipment special, and production efficiency is low, and production cost is high, affects productivity effect.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned deficiency, thering is provided a kind of high-performance wireless charging device, its space magnetic loss rate is little, and ACR can be avoided bad, winding volume is little, take up room little, can be with mould molding, it is not necessary to artificial or mechanical coiling, consumptive material is few, production efficiency is high, and production cost is low, and benefit improves notable.
For reaching above-mentioned purpose, the technical scheme is that, this high-performance wireless charging device, including being installed on the coil of magnetic core base, the cross section around prepared material of described coil is non-circular.
The cross section around prepared material of described coil is rectangle.
The cross section around prepared material of described coil is square.
The pitch of the laps around the coiling of prepared material institute of each winding of described coil is in same plane.
The interval around each pitch of the laps of prepared material institute coiling of described coil is consistent.
Described coil is integrally formed to have some discoid bodies being in conplane flat sheet-like pitch of the laps.
With existing Wireless charging coil Technical comparing, the cross section around prepared material of coil of the present invention is non-circular rectangle or square, it is in same plane by each pitch of the laps around prepared material coiling, the interval of each pitch of the laps is consistent, each coil windings is to have some discoid bodies being in the consistent flat sheet-like pitch of the laps composition in conplane interval, make the coil windings can be with global formation, can make with unitary mould molding or employing copper coin punching press, concordance is good, eliminate the step sequence such as coiling and coil sizing, and, use copper coin punching press, D.C. resistance is less, simple for assembly process, 60% is improved by self-adhesion twisted wire production efficiency than conventional coil, eliminate tradition twisted wire coiling and be susceptible to the bad phenomenon of ACR.
After coil design of the present invention uses copper coin punching press peripheral spray insulation again instead, winding volume is significantly reduced, and copper loss also has and reduces significantly, and coil loss is less, in hgher efficiency, especially significantly reduce space magnetic loss rate, ACR can be avoided bad, coil die molding, assemble more simple and convenient, it is more convenient for batch production, greatly reduces machining period, improve production efficiency and benefit.
Present invention is mainly used for electric automobile, the wireless charging in smart mobile phone field, test shows, its space magnetic loss rate reduces by 85%, receive the usefulness sent out and improve 20%, and ACR can be avoided bad, winding volume is little, takes up room little, can be with mould molding, without artificial or mechanical coiling, consumptive material is few, and production efficiency is high, production cost is low, and benefit improves notable.
