Example, and be used to together with specification to explain the principle of the application.
Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
This application provides a kind of wireless charging method, the wireless charging method be applied to first terminal and second terminal it
Between, wherein, first terminal can be one or more, and similarly, second terminal can also be one or more, when first terminal and
When second terminal is respectively multiple, wherein, each first terminal can be as power supply terminal, and each second terminal can be as filling
Electric terminals, vice versa.
However, it is desirable to which the quantity of explanation, first terminal and second terminal can be with unequal, for example, can pass through two
Individual first terminal is a second terminal charging, can also be that two second terminals charge by a first terminal.
In the application, for the sake of clarity, carried out with the embodiment that first terminal and second terminal are respectively set to one
Illustrate, wherein, first terminal is used as charging terminal as power supply terminal, second terminal.Pass through the explanation to this embodiment, ability
Domain skill personnel should be appreciated that when setting multiple first terminals and multiple second terminals respectively, still can be real between each terminal
Existing wireless charging.
As shown in figure 1, the wireless charging method comprises the following steps：
Step 10, first terminal and second terminal are individually positioned in the predetermined position of wireless charging pattern, now, the
One terminal and second terminal can be with bonded to each other, can also be spaced a predetermined distance from.
, can be by between the two in order to ensure charge efficiency when first terminal and second terminal spaced a predetermined distance from
Distance is limited within 3mm, and described " preset distance " is referred to when two terminals are placed with identical posture herein, and two
Interval between person.
Next, in step 20, first terminal is arranged into power supply state, under power supply state, first terminal is produced
First magnetic field, meanwhile, second terminal is arranged to charged state, in the charge state, second terminal produces the second magnetic field.
The mode that first terminal is arranged to power supply state is had a variety of, a kind of mode is that the power supply for opening first terminal is opened
Close, such as button or slide switch lamp；Another way is to open power supply setting options in first terminal.Similarly, by second
Terminal is arranged to the mode of charged state ibid.Here is omitted.
After the first magnetic field and the second magnetic field are produced, the first magnetic field can intercouple with the second magnetic field, be managed according to electromagnetism
By the magnetic field after coupling can produce induced-current in second terminal.Because the induced-current that magnetic field induction comes out is usually
Alternating current, it is impossible to directly powered for second terminal, therefore, the wireless charging method also includes step 30.
In step 30, rectification is carried out to induced-current, converts alternating current to direct current, now, the direct current can be with
It is second terminal charging as power supply.
The mode of rectification has a variety of, and one is by the sensing of form of communication by the rectification circuit that is arranged in second terminal
Circuit conversion is direct current, and one is to carry out rectification by commutation diode.
Description more than, realizes wireless charging, so that second terminal between first terminal and second terminal
Charging be no longer dependent on power interface and power line so that the work of people and live more convenient.
Further, as shown in Fig. 2 in step 30, step 32 can also be included, in the step 32, be filled with direct current
Before second terminal, the voltage of stable DC electricity.That is, keeping direct current whole with metastable control source second
End, keeps electric current is stable can be realized by mu balanced circuit or stable-pressure device.
After second terminal charging is finished, the electricity manual termination wireless charging that operator can be according to second terminal
Power mode, for example, first terminal or second terminal are removed, both relative distance of increase, the distance when between the two exceedes
During preset distance, the first magnetic field and the second magnetic field can not be coupled due to distant, thus, wireless charging mode ends；And for example,
The power supply state of manual-lock first terminal or the charged state of manual-lock second terminal, artificially terminate wireless charging pattern.
In order to further improve in the convenience of wireless charging pattern, the application, wireless charging method also includes step 40,
As shown in figure 3, in step 40, when second terminal charging complete, the wireless charging pattern of first terminal and second terminal is certainly

Terminal using wireless charging method when being charged at night, and the effect produced by the step is especially protruded.
Alternatively, the automatic step 40 for terminating wireless charging pattern can have a variety of different way of example, Yi Zhongshi
Example is applied, step 40 can include step 41, in step 41, the charging circuit in control second terminal disconnects automatically, which
Even if so that the first magnetic field and the second magnetic field still intercouple, but because charging circuit disconnects, can not after the magnetic coupling yet
Induced-current is produced in the charge circuit, so that wireless charging mode ends；Another embodiment, step 40 can include
Step 42, in step 42, under the automatic charged state for terminating second terminal, non-charged state, the second magnetic field disappears, which
So that second terminal is no longer on charged state, and then causes second terminal no longer to produce the second magnetic field, so that by wireless charging
In mode ends, this embodiment, because second terminal no longer produces the second magnetic field, therefore, the energy consumption of second terminal is reduced, saved
Power saving energy.
In the present embodiment, step 40 both includes step 41, step 42 is included again, step 41 and step 42 pass through two kinds of approach
Wireless charging pattern is terminated, the reliability of wireless charging mode ends is improved.
On the other hand, can also be by controlling the charging circuit of first terminal to disconnect and terminate automatically second terminal automatically
The mode of charged state make wireless charging mode ends.Specifically, as shown in figure 5, step 40 can also include step 43,
In step 43, the power supply circuit in control first terminal disconnects automatically；Or, step 40 can include step 44, in step 44
In, the automatic power supply state for terminating first terminal, to cause the first magnetic field to disappear；Or, step 40 both includes step 43, again
Including step 44.Step 43 has identical technique effect with step 41, step 44 and step 42, and here is omitted.
In addition, for using first terminal, as power supply terminal, it is in order to produce the first magnetic field, its voltage provided
Value has an acutely soaring process, causes first terminal overvoltage in order to avoid magnitude of voltage fluctuation is larger, alternatively, the wireless charging
Method for electrically also includes step 50, in step 50, and overvoltage protection, over-voltage protecting function are carried out to the first terminal under power supply state
