While exceeding the receiving area 105 of point centered by secondary coil 21 according to the primary winding mark 104 of the position of described primary winding 13, be shown as align-err, when interior in described receiving area 105 according to the primary winding mark 104 of primary winding 13 positions, be shown as and arrange normally.

Described ordered state procedure for displaying (step S50) is also exported align-err and is arranged the normal buzz of difference mutually.

The present invention is illustrated wireless charging system as an example of smart mobile phone 3 example, but is not to be limited, all applicable for any mobile phone that possesses display frame.The structure of wireless charging transport unit 10 and wireless charging acceptance division 20 also just represents common general introduction, is not to be limited.The present invention at least installs three cell windings at the secondary coil periphery of wireless charging acceptance division, receive the induced current transmitting from primary winding, detect reception power strength, be presented on picture detect the position of primary winding according to this reception power strength after.

When smart mobile phone 3 is placed on charging panel 2, the induced current receiver voltage that sensor coil 110 can transmit by primary winding 13.Then examinations receiving intensity process 10, detects each reception power strength from three sensor coils 110.In receiving intensity testing process (step S10), if detect electric power from more than one sensor coil, come into effect according to wireless charging ordered state of the present invention and show and control.That is to say, smart mobile phone 3 shows that away from ordered state under the state of charging panel 2 control does not move, and being placed on charging panel 2 from sensor coil 110, smart mobile phone 3 starts to detect while receiving power strength, just come into effect list view and control, here detecting and receiving the method for power strength is that to detect voltage be that example describes.

At least install in addition under the state of three sensor coils 110 and detect receiving intensity, the reception electric power of each sensor coil is implemented align-err procedure for displaying (step S60) lower than predefined minimum value.That is to say, install when primary winding in charging panel 2, smart mobile phone 3 is placed on charging panel 2 and by edge and is tangled, cannot detect the position of primary winding and show align-err.

After setting the position coordinates of three sensor coils, generate respectively the circular function of the radius being inversely proportional to the receiving intensity of the middle each sensor coil detecting of described receiving intensity testing process (step S10).Generate the circular function of known central point and radius according to mathematical expression.For example, when maximum receiving intensity is 5V, radius of a circle is set as 1cm, and when receiving intensity is 3V, radius of a circle is 3cm, and when receiving intensity is 1V, radius of a circle is 5cm.After setting thus, generate the circular function that radius of a circle and receiving intensity are inversely proportional to.

Therefore, as shown in Figure 6B, the circle of receiving coil A101 is minimum, nearest between expression primary winding 13 and sensor coil A101, and in the middle of receiving coil B102 represents, receiving coil C103 represents from centre (centres of three sensor coils) state farthest.

Generate three circular functions according to the receiving intensity detecting from three sensor coils 110, implement primary winding position probing process (step S40), explain three circular functions, what three circles were met a bit detects as primary winding position.Now the position of primary winding is as detected with the corresponding position of sensor coil coordinate.

The demonstration of picture is the central center point using the coordinate of secondary coil as picture, and the circle that presets diameter is shown as receiving area 105, and the position of the primary winding of described detection is presented on picture together as primary winding mark 104.

(A) of Fig. 7 and (B) be the ordered state display frame illustration figure according to wireless charging system of the present invention, (A) of Fig. 7 represents to be arranged in Centromedian state, and Fig. 7 (B) represents away from Centromedian state.

In the present invention, the desired location of secondary coil 21 is set in the centre of picture, the circle of predefined diameter is shown as receiving area 105, the position of the primary winding of detection is presented on picture as primary winding mark 104.Thereupon, primary winding mark 104 is shown as ordered state while entering receiving area 105 normal, and as shown in Figure 6B, primary winding mark 104 shows on the position that exceeds receiving area 105, shows ordered state mistake.And can circulate a notice of respectively normal and error condition with buzz.

Although and do not show on accompanying drawing, but for being easy to confirm centre point, be presented at the horizontal and vertical lines that centre is met, be also shown as circle by dummy line for the primary winding transit area centered by primary winding 104, strengthen ordered state intuitive and be convenient to observe.

According to the present invention, meeting display radio charging ordered state on smart mobile phone picture, therefore be easy to shift position and aim at ordered state, make it to become normal alignment state, be easy to aim at ordered state and make wireless charging efficiency be arranged in optimum efficiency, preventing to cause because of align-err the problem of charging interval prolongation.
