It refer again to shown in Fig. 1, in another embodiment, the wireless charger 10 also includes communication module 15；
The controller 14 obtains the charge efficiency of charging equipment by the communication module 15, judges described to be charged
Whether the charge efficiency of equipment meets preset value；If the charge efficiency of the charging equipment is unsatisfactory for preset value, is generated
Three control signals give the drive module 12；
The drive module 12, for parsing the 3rd control signal, obtain corresponding to the 3rd control signal the
Three area informations, driven according to the 3rd area information and controllable opened on the metal lattice 11 positioned at first area is borderline
Shut-off is opened, and drives the gate-controlled switch conducting on the 3rd zone boundary, to cause in the region of metal lattice 11 the 3rd
Metal dots connect to form tertiary coil described in tertiary coil and generate induced field in the energized state to the charging equipment
Charged.
It should be noted that the charge efficiency of charging equipment is unsatisfactory for preset value, reason is for charging equipment and wirelessly
The coil of charger does not have accurate contraposition, and in general solution is mobile charging equipment so as to the coil with wireless charger
Accurate contraposition, this mode cause charging equipment freely to be placed in wireless charger.
Present embodiment is by judging whether the charge efficiency of charging equipment meets preset value；If the charging equipment
Charge efficiency be unsatisfactory for preset value, then generate the 3rd control signal give the drive module 12；Drive module 12 is according to control
The 3rd control signal that device 14 generates, the borderline gate-controlled switch in driving metal lattice 11 first area disconnects, and drives the 3rd
Gate-controlled switch conducting on zone boundary, to cause the metal dots on the zone boundary of metal lattice 11 the 3rd to connect to form the 3rd line
Circle, tertiary coil can equally generate induced field in the energized state.
It should be noted that the 3rd control signal is different control signals from the first control signal.The face of tertiary coil
Product can be more than or equal to the area of first coil, i.e., can spread loop when the charge efficiency of charging equipment is unsatisfactory for preset value
Area (position of coil can be identical or different with the position of original coil) detection charging equipment charge efficiency whether have
Improve；Or coil area is constant but the position difference of the position of coil and original coil detects charging equipment
Whether charge efficiency is improved.It should be understood that if the area of coil is big, power consumption may be more easy to, therefore in order to save electricity
The situation that the area of tertiary coil is less than the area of first coil is also possible.
Optionally, the shape of the 3rd transmitting coil is different from the attribute of first transmitting coil, the attribute bag
Include：Shape, size and position.
It should also be noted that, the shape of the 3rd transmitting coil can be different from shape, the size of the first transmitting coil,
The shape of even the first transmitting coil is circular, then the shape of the 3rd transmitting coil can be rectangle, oblong-shaped etc..
It should be understood that if the charge efficiency of charging equipment is still unsatisfactory for preset value after once detecting, can continue according to
Aforesaid way is detected, and sends control signal again, by the state for adjusting multiple gate-controlled switches so that the position of transmitting coil
Put, shape or size change, until the charge efficiency of charging equipment meets preset value.
For the further explaination embodiment of the present invention one, now carried out by taking wireless charger charging structure shown in Fig. 7 as an example detailed
Explanation.
Figure 7 illustrates the metal lattice of mobile terminal and charging equipment, wherein charging equipment includes receiving terminal
Coil (accompanying drawing is not shown).
On wireless charger after electricity, the metal dots for opening FX can be given tacit consent to, such as by controller and drive module
Shown in tetra- coils of A, B, C, D shown in figure.
(it can optionally be placed when charging equipment is placed on metal lattice, smart mobile phone assumed in this example
The position of placement is as shown in the E coils in figure), now E coils only have that sub-fraction is overlapping with A coils, therefore charging equipment
Charge efficiency can be relatively low.
When wireless charger obtains by communication module the charge efficiency of charging equipment, and filling for charging equipment is judged
When electrical efficiency is unsatisfactory for preset value, then by controller and drive module, a coil (coil surface reopened is reopened
With A coils as, position appears like and moved right A coils are past on the right of A coils product from figure).
It should be noted that the coil reopened, its position, shape, size can change.It is as shown in fig. 7, parallel
Quadrangle is the coil that B coils reopen.In other embodiments, the quantity of the coil reopened can also change,
To increase charge efficiency.
Wireless charger reacquires the charge efficiency of smart mobile phone by communication module, and judges filling for charging equipment
Whether electrical efficiency meets preset value, is charged if preset value is met according to the coil reopened.Otherwise continue to lead to
Cross and adjust the states of multiple gate-controlled switches and reopen coil until detecting the charge efficiency of charging equipment meets preset value.
In one embodiment, the moving direction of relatively described first transmitting coil of the 3rd transmitting coil is towards institute
State the moving direction of charging equipment.
Specifically, Fig. 7 is refer again to, in a kind of implement scene, is entered when being moved on mobile terminals with charging equipment
The explanation of row charging：
On wireless charger after electricity, the metal dots for opening FX can be given tacit consent to, such as by controller and drive module
Shown in tetra- coils of A, B, C, D shown in figure.
When smart mobile phone is placed on metal lattice (in this example it will again be assumed that in the position of charging equipment placement such as figure
E coils shown in), now E coils only have that sub-fraction is overlapping with A coils, therefore the charge efficiency of smart mobile phone is certainly very low.
Assuming that charging equipment now moves in the horizontal direction, i.e., it is mobile to the left or to the right (to be moved to B coils or D coils
Move as similar situation).
If charging equipment is moved to the left, with upper described similar, when charging device obtained by communication module it is to be charged
The charge efficiency of equipment, and when judging that the charge efficiency of charging equipment is unsatisfactory for preset value, then pass through controller and driving mould
Block, reopen a coil (direction of unlatching on the right of A coils, being appeared like A coils from figure toward moving right).
Then charged after meeting preset value according to the coil reopened.
If charging equipment moves right, opening ways are similar during with being moved to the left, and the direction of opening coil is still in A lines
The right (appeared like from figure by A coils toward move right) of circle, such a mode can still be realized under certain condition.If treat
When charging equipment moves right to coil C regions, at this time it be able to can also be realized by C coils toward moving left.
In another embodiment, the controller obtains the charging of multiple charging equipments by the communication module
Efficiency, judges whether the charge efficiency of the multiple charging equipment meets preset value；If the multiple charging equipment fills
Electrical efficiency is unsatisfactory for preset value, then generates the 4th control signal and give the drive module；
The drive module, for the 4th control signal generated according to the controller, obtain the 4th control letter
4th area information corresponding to number, driven according to the 3rd area information on the metal lattice on the 3rd zone boundary
Gate-controlled switch disconnect, and the gate-controlled switch conducting on the 4th zone boundary is driven, to be located at the metal lattice
