UART pins, and the inquiry whether adapter supports fast charge mode is sent from terminal device to adapter.Work as adapter
When supporting fast charge mode, the response for representing to support fast charge mode is sent to terminal device, and switches to USB.When
When terminal device receives the response of the support fast charge mode from adapter, pin is switched to USB, so as to pass through
USB carries out quick charge.If terminal device does not support fast charge mode, inquiry would not be sent to adapter, therefore
It will not carry out quick charge.If adapter does not support fast charge mode, response will not be sent for the inquiry, therefore
It will not carry out quick charge.In this case, adapter will charge to terminal device according to 5V normal voltages.
However, being not difficult to find out, traditional handshake method needs terminal device and adapter be equipped with UART pins and
Switch unit between UART and USB.Such structure not only results in the increase of cost, the meeting when switch unit breaks down
Lead to not charge, there is higher failure risk.
The content of the invention
The present invention is in view of Yi Shang problem is completed, it is intended that providing a kind of charging method, terminal device and adaptation

【Charging method applied to terminal device】
In the following, carry out the charging method applied to terminal device that the present invention will be described in detail with reference to attached drawing.Fig. 2 is according to this hair
The flow chart of the charging method applied to terminal device of bright embodiment.As shown in Fig. 2, this method includes：
First, detected whether that charge power supply is connected to the first interface (step S210).Terminal device can pass through
First interface charges, but first interface is not limited to be exclusively used in the interface to charge, can also be not only chargeable but also can transmit number
According to interface.Typically, first interface can be that USB interface, Mini-USB interfaces, Micro-USB interfaces, Lightning connect
Mouth is but it is also possible to be other any interfaces with charge function.(the step when not detecting that charge power supply is connected to interface
S210, no), continue to detect whether to be connected to first interface by charge power supply back to step S210.
It is (step S210, yes) when detecting that charge power supply is connected to first interface, you can start to charge up.At this point, terminal
The size that equipment can control charging current to cause charging current changes according to the waveform of regulation.In the following, description is according to regulation
One example of the electric current of waveform variation.In this example, the electric current changed according to the waveform of regulation is from the first current value rank
Ladder type increases to the second current value, then drops to first current value from the second current value step type.Fig. 3 is to represent
One exemplary figure of the charging current that the waveform according to regulation changes.In figure 3, abscissa represents the time, and ordinate represents

Charge parameter setup module is pressed when the charging voltage that the charging voltage detection module detects rises to defined threshold
Charge parameter is set according to the second charge mode, when the charging voltage that the charging voltage detection module detects does not rise to rule
When determining threshold value, charge parameter is set according to the first charge mode, wherein the charging voltage of first charge mode is less than described
The charging voltage of second charge mode.
7. terminal device as claimed in claim 5, wherein,
The electric current that the waveform according to regulation changes is to increase to the second current value from the first current value step type, then from institute
It states the second current value step type and drops to first current value.
8. a kind of adapter can be charged by first interface using the second charge mode to terminal device, including：
Current detection module configures to detect the size of charging current；
Judgment module, configures to judge whether the size of detected charging current changes according to the waveform of regulation, to determine institute
State whether terminal device supports fast charge mode；
Charging voltage setup module, configuration are judged as the size of detected charging current according to the rules to work as the judgment module
Waveform variation when, determine that the terminal device supports fast charge mode, charging voltage be promoted to more than defined threshold；
Wherein, the electric current that the waveform according to regulation changes is to increase to the second current value from the first current value step type, with
Drop to first current value from the second current value step type afterwards.
