Second embodiment
With reference to Fig. 4, the flow chart of the method for the data transmission of second embodiment of the invention is shown, can specifically include such as
Lower step：
Step 401, when the CC1 pins of the Type-C interfaces of mobile terminal detect pull-up level, identification has charger
Access the mobile terminal；
In embodiments of the present invention, the mobile terminal can be the electronic equipment for having Type-C interfaces, for example, intelligence
Mobile phone, tablet computer etc., the embodiment of the present invention are not construed as limiting the concrete type of mobile terminal.
In the concrete realization, the circumscribed USB Type-C interfaces of mobile terminal can be connect with a Type-C Hub.It fills
The external equipments such as electric appliance or storage device can realize the connection between mobile terminal by accessing the Type-C Hub.

Stream source pulls up, so as to generate level change.Therefore, ground is pulled down to when the CC2 pins of mobile terminal Type-C interfaces detect
During level, it is believed that there is storage device to access the mobile terminal.
In embodiments of the present invention, by different CC pins (CC1 pins and CC2 pins) respectively to the equipment of access into
Row detection so that mobile terminal can both receive the charging of main equipment charger as slave device, can also be used as main equipment and
The external slave device such as storage device is into row data communication.
Step 404, the charger is powered to the storage device；
In general, storage device is connect with other equipment, and when carrying out data transmission, need to supply it by other equipment
Electricity could realize corresponding function.
In embodiments of the present invention, when charger and storage device access mobile terminal simultaneously, due to Type-C interfaces
Vbus pins on have the voltage output of 5V, therefore, the vbus pins that can Type-C interfaces be directly passed through by the charger
It powers to the storage device.
If it should be noted that before storage device accesses mobile terminal, charger is not detected and accesses movement end
End, then need to be powered from the mobile terminal to the storage device；Alternatively, movement is accessed simultaneously in charger and storage device
After terminal, since mobile terminal charging is full or other reasons are disconnected the connection of charger and mobile terminal, then need to switch to
It is powered from the mobile terminal to the storage device.
Step 405, carried out data transmission by the D+/D- pins and the storage device of the Type-C interfaces, it is described
Data transmission is performed according to 2.0 protocol specifications of USB.
In embodiments of the present invention, when charger and storage device access mobile terminal simultaneously, the mobile terminal can
To be carried out data transmission by the D+/D- pins of Type-C interfaces with the storage device, realize when charging for mobile terminal,
Data transmission between mobile terminal and storage device.
In the concrete realization, the data transmission between mobile terminal and external storage device can be according to USB2.0 agreements
Regulation enforcement.
In embodiments of the present invention, when charger and storage device access mobile terminal simultaneously, pass through Type-C interfaces
The charging completed between charger and mobile terminal of TX+/TX- pins shake hands, pass through D+/D- pins and realize storage device with moving
Data transmission between dynamic so that charge to mobile terminal and can be carried out at the same time to storage device transmission data, improve shifting
The efficiency of dynamic terminal charge and data transmission enhances the convenience of mobile terminal operation.
It should be noted that for embodiment of the method, in order to be briefly described, therefore it is all expressed as to a series of action group
It closes, but those skilled in the art should know, the embodiment of the present invention is not limited by described sequence of movement, because according to
According to the embodiment of the present invention, certain steps may be used other sequences or be carried out at the same time.Secondly, those skilled in the art also should
Know, embodiment described in this description belongs to preferred embodiment, and the involved action not necessarily present invention is implemented
Necessary to example.
