Abstract
The invention provides a multi-coil wireless charger which comprises a transmitting coil array and a coil selector. The transmitting coil array is used for transmitting electromagnetic waves of specific frequency, and the coil selector is used for enabling a certain transmitting coil in the transmitting coil array. The multi-coil wireless charger has the advantages that the problem of lowering of charging efficiency due to misplacement between the transmitting coils of the wireless charger and receiving coils in a portable electronic product is solved.
Description
Technical field
The invention belongs to electric energy wireless transmission field, especially relate to a kind of multi-coil wireless charger.
Background technology
In existing technology, wireless charging is the wireless transmission being realized electric energy by electromagnetic induction, therefore, the dislocation of transmitting coil and receiving coil has influence on charge efficiency significantly, and existing wireless charger only has a transmitting coil cannot charge to the equipment of receiving coil at diverse location.There is the technical problem that wireless charger cannot be general.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of multi-coil wireless charger, is especially applicable to the mancarried electronic aid different to receiving coil position and carries out wireless charging.
For solving above-mentioned purpose, the technical solution used in the present invention is: a kind of multi-coil wireless charger comprises transmitting coil array and coil selector, and described coil selector selects and certain transmitting coil enable makes it launch the electromagnetic wave of certain frequency.
Described transmitting coil array is made up of multiple transmitting coil.
Described coil selector is used for selecting and certain transmitting coil in enable described transmitting coil array.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, wireless charger is applicable to different mancarried electronic aids, has highly versatile, charge efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is operation principle schematic diagram of the present invention.
In figure: 1, transmitting coil 2, coil selector 3, receiving coil
Embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present invention is explained.
As shown in Figure 1, a kind of multi-coil wireless charger comprises transmitting coil array and coil selector 2, and described transmitting coil array is made up of multiple transmitting coil 1.
Its working method is: as shown in Figure 2, when in mancarried electronic aid receiving coil 3 near transmitting coil 1 time, coil selector 2 can select and enable with receiving coil array in misplace transmitting coil 1 minimum, it is made to launch the electromagnetic wave of certain frequency, receiving coil 3 receives the electromagnetic wave that transmitting coil 1 is launched, and the electromagnetic wave that receiving coil 3 receives is charged to the battery in mancarried electronic aid by the change-over circuit in mancarried electronic aid again.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
