Description
Technical field
The present invention relates to charging technique field more particularly to a kind of efficient wireless charging methods and wireless charging device.
Background technique
Mobile phone is ubiquitous for the communication tool of representative, therefore the convenience to charge just seems particularly significant, and at present in vapour
Vehicle field nearly all uses wireline interface to charge such as cell phone type mini electrical equipment, it is difficult to meet multi-section electrical equipment use
When the trouble that charges, and charging cable can be brought mutually to wind to occupant even cause security risk, while influencing in vehicle
Adorn space perception.
However, existing wired charger is seemed in relatively narrow driver's cabin in this way with very long data line
It is very in disorder, it also will affect the safety of driving.In addition, although existing wireless charger can be on general desk or plane
It places, but position can not be fixed on the driving vehicle to jolt, user is caused to be difficult to place, be also not susceptible to grasp it in traveling and fill
Electric situation.
The invention that China Patent Publication No. is CN202888876U discloses a kind of vehicle carried mobile phone on April 17th, 2013 and fills
Electric appliance, including fixed frame and charging plug, which is characterized in that fixed frame is equipped with backboard, and backboard one end is connect with charging plug, Gu
Determine to be equipped with spring platform on the inside of the upper and lower of frame front, mobile phone is secured within to be connect with charging plug, fixed frame back side upper and lower
Inside is equipped with fixing clamp formation grip force and is fixedly secured on rearview mirror in the car.The configuration of the present invention is simple, fixed position conveniently make
It with mobile phone is checked, charges immediately for mobile phone, guarantees that electricity is sufficient, harness hides placement, does not influence sight not and will cause interior sky
Between it is in disorder, facilitate plug mobile phone, convenient for the application of smart phone function in the car, be suitable for various room mirror and more
Kind model mobile phone.
People are frequently necessary to common portable electronic device, and placement uses in the car or in the car.Due to a little class electricity
Sub-device is essentially all battery power supply, with making and cell degradation for a long time for electronic device, the electronics dress of limited electricity
Set can often be in the presence of it is out of power.

Give power receiving device.Currently, wireless charging technology summary is divided into three big camps, wireless charging Electricity Federation alliance Wireless Power
Qi specification, electric utility alliance Power Matters Alliance (PMA) and the radio that Consortium (WPC) is formulated
The Rezence specification that source alliance Alliance for Wireless Power (A4WP) is formulated.Wherein with WPC, A4WP alliance
Then there is the technology of magnetic induction (low frequency) and magnetic resonance (high frequency) to distinguish for the wireless charging mode of mainstream, and use.Magnetic induction side
Formula is simply possible to use in short-distance transmission and power receiving device need to align and be attached at power supply unit, and energy conversion efficiency is higher, is but difficult to
It realizes multiple power receiving devices while charging.Magnetic resonance is then to allow transmitting terminal and receiving end reaches specific resonance frequency, can be with
It allows both sides to form electromagnetic induction phenomenon, achievees the purpose that energy transmission in this way.Compared to magnetic induction way, magnetic resonance side
Longer-distance charging may be implemented in formula.
In existing wireless charging technology, need to use two components: one is the pedestal with emission function (as emitted
Plate), another is the electronic equipment (such as mobile phone with receive capabilities, MP3) with receive capabilities, wherein the pedestal with emission function
In include primary coil, so that primary coil is in emission state by Alternating Current Power Supply, be arranged in the electronic equipment with receive capabilities
Secondary coil, the primary coil which is in emission state carry out electromagnetic coupling and obtain electric energy.
In daily life, work and leisure, the power consumption of smart phone is relatively large, needs to supplement electricity at any time, due to
Traditional wired charging mode in use, needs plug charging plug repeatedly, be easy to cause interface to damage, cause not
It can charge, and data line is easily lost, bad connection, it is inconvenient for use.It is set moreover, the prior art also cannot achieve charging reception
Standby and wireless charging transmitter existence two-way detection.
And now how in vehicle travel process it is convenient and efficient efficiently carry out mobile phone charging operations, improve the peace of automobile
Full property and convenience are present technology problems to be solved, to realize that people can charge anywhere or anytime, and are avoided wired
Charge disadvantage.
