Description

A kind of efficient wireless charging method and wireless charging device
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.
