Step 101, detecting the level state of the CC1 pin and/or the CC2 pin;

In the embodiment of the present invention, two charging devices can be used to simultaneously connect and charge the mobile terminal.

In a specific implementation, the USB Type-C interface of the mobile terminal may be connected to a Type-C adapter. The adapter is a kind of power adapter, which can convert a class interface into an interface required by the invention, so that two class interfaces that cannot work together due to interface mismatch can work together. Type-C adapter is a device that can expand one USB Type-C interface into multiple ones, and enable these interfaces to be used at the same time.

As shown in Figure 2, it is a schematic diagram of the connection between a charging device and a mobile terminal according to the present invention. In each charging device shown in Figure 2, the interface is a Type-C interface, when the USB Type-C interface of the mobile terminal After being connected with a Type-C adapter, the first charging device (charger 1) and the second charging device (charger 2) can be respectively inserted into the two interfaces of the Type-C adapter to form a complete charging device.

Generally, a USB Type-C interface may include a Type-C female connector and a Type-C male connector, as shown in FIGS. 3A and 3B , which are structural diagrams of the Type-C female connector and the Type-C male connector, respectively. The Type-C female head includes 24 pins (PIN), including 4 Vbus pins, 4 TX pins (2 TX- pins and 2 TX+ pins), 4 RX pins (2 RX- pins and 2 RX+ pins) and 2 CC pins (CC1 pins and CC2 pins); while the Type-C male head includes 22 pins, which is less than the Type-C female head A pair of D+/D- pins, the Type-C male header also includes 4 Vbus pins, 4 TX pins, 4 RX pins and 2 CC pins.

In the embodiment of the present invention, the Type-C interface on the mobile terminal in Figure 2 can be a Type-C female head, and the Type-C adapter directly connected to it includes a Type-C male head and two Type-C -C female. Specifically, the Type-C female head on the mobile terminal side is connected to a Type-C male head on the Type-C adapter, and the Type-C male head is connected to two Type-C female heads in the Type-C adapter , two Type-C female connectors can be connected to the first charging device and the second charging device respectively.

In the embodiment of the present invention, the pins of the Type-C interface of the mobile terminal can be divided into two charging paths, specifically, the pins on the Type-C female head and the Type-C male head can be divided into two groups Charging path, the first charging path includes the D+ pin and 2 D- pins of the Type-C female head, the second charging path includes 4 Vbus pins of the Type-C female head, and the CC pin is two charging paths Commonly, specifically, the first charging path includes the CC1 pin, and the second charging path includes the CC2 pin.

In the Type-C adapter, after the two CC pins in the female header 1 are connected together, they are connected to the CC1 pin of the adapter male header through Vbus1, and after the two CC pins in the female header 2 are connected together, pass Vbus2 is connected to the CC2 pin of the adapter male.

In the embodiment of the present invention, the access detection of the charging device can be completed according to the CC pin.

Step 102, using the level state of the CC1 pin to determine whether a first charging device is connected, and using the level state of the CC2 pin to determine whether a second charging device is connected;

In a specific implementation, the level status of the CC1 pin corresponding to the first charging device and the CC2 pin corresponding to the second charging device can be detected in real time, and it can be determined that a charging device is connected according to the level status of the two CC pins Still have two charging devices plugged in.

Step 103, when it is determined that there is a first charging device connected, use the 2 D+ pins and 2 D- pins of the first charging path to charge the mobile terminal, and when it is determined that there is a second charging device When connected, use the Vbus pin of the second charging path to charge the mobile terminal.

In the embodiment of the present invention, when it is determined that two charging devices are connected, the battery (Battery) of the mobile terminal can be charged by connecting the DCDC circuit with 2 D+ pins and 2 D- pins in the first charging path , and, the 4 Vbus pins in the second charging path are connected to the DCDC circuit to charge the battery of the mobile terminal. Through the above method, when the output capacity of a single charging device is limited, two charging devices are charged at the same time to increase the charging speed.

In this way, in the embodiment of the present invention, the pins of the Type-C interface of the mobile terminal are divided into the first charging path and the second charging path. When the first charging device and/or the second charging device are connected, they can respectively pass through the 2 D+ pins and 2 D- pins of the first charging path, and/or, the Vbus pin of the second charging path is the mobile terminal For charging, the mobile terminal is powered by two charging devices, which improves the charging speed of the mobile terminal and solves the problem of long time consumption for charging the mobile terminal in the prior art.

Embodiment two

Referring to FIG. 5 , it shows a flow chart of the steps of a charging method embodiment of Embodiment 1 of the present invention, which is applied to a mobile terminal with a Type C interface, and the pins of the Type C interface are divided into the first charging path and the second charging path. Two charging paths, the first charging path includes CC1 pins, 2 D+ pins and 2 D- pins, the second charging path includes CC2 pins and Vbus pins, and the method can specifically include the following step:

Step 201, detecting the level state of the CC1 pin and/or the CC2 pin;

In the embodiment of the present invention, the access detection of the charging device can be completed according to the CC pin.

Step 202, using the level state of the CC1 pin to determine whether a first charging device is connected, and using the level state of the CC2 pin to determine whether a second charging device is connected;

In the embodiment of the present invention, the access detection of the charging device can be completed according to the CC pin.

In a preferred embodiment of the present invention, the step 202 may include:

Detecting the level states of the CC1 pin and the CC2 pin respectively;

When it is detected that the level state of the CC1 pin changes, it is determined that there is a first charging device connected, and when it is detected that the level state of the CC2 pin changes, it is determined that there is a second charging device Device access.

In the embodiment of the present invention, as shown in Figure 2, it can be judged by the level state of the CC1 pin whether there is a charger 1 inserted in the female connector 1, and the female connector can be judged by the level state of the CC2 pin 2. Is there charger 2 plugged in? Specifically, the CC pin of the charger is always pulled up by a current source and can only be used as the master device. At this time, the mobile terminal can only be used as the slave device. The level of the pin is pulled down.

For example, the CC pin in the female connector 1 is pulled up by the charger 1, and the CC1 pin of the mobile terminal is pulled up by the charger 1. The mobile terminal knows that there is a charger 1 inserted in the female connector 1, and the mobile terminal passes the CC2 pin through The Rd resistor is pulled down to complete the insertion detection. The detection method of the charger 2 is the same.

In a preferred embodiment of the present invention, the first charging path includes TX+ pins and TX- pins, the second charging path includes RX+ pins and RX- pins, and the method may further include:

Performing a charging handshake with the first charging device through the TX+ pin and the TX- pin of the first charging path, so as to determine the charging parameters of the first charging device;

The charging handshake is performed with the second charging device through the RX+ pin and the RX- pin of the second charging path, so as to determine the charging parameters of the second charging device.

In the embodiment of the present invention, when the charger 1 is inserted into the Type-C adapter, the male head of the Type-C adapter and the CC1 pin of the female head of the Type-C adapter of the mobile terminal can detect the connection of the charger 1, Therefore, it can communicate with the processor, and send the message of charger 1 to the processor. After receiving the above message, the processor can control the TX+ pin, TX- pin, RX+ pin and RX- pin of the mobile terminal to Configure charging parameters.

The specific charging handshake process is that the TX+/- pin and the RX+/- pin form a path for information exchange between the mobile terminal and the charger during the charging process. The charging parameters that need to be interacted include voltage, current, and so on. For example, when the temperature of the mobile terminal is relatively high, it is necessary to adjust the charger to output a relatively small charging current for charging. Charging parameters can be transmitted through TX+/- pins or RX+/- pins.

Specifically, take the TX+/- pin as an example. For example, the mobile terminal pulls the TX+ pin up to 1.8V, and pulls the TX- pin down to 0V, indicating that the charging current is 500mA. Charger 1 detects that the TX+ pin and TX - After leveling the pin, adjust the output current of charger 1 to 500mA, thus completing a configuration process. The RX+/- pins are the same, so I won't repeat them here.

Step 203, when it is determined that the first charging device is connected, switch the switch of the mobile terminal to the first charging path, and use the 2 D+ pins and 2 D- pins of the first charging path Charge the mobile terminal.

In a preferred embodiment of the present invention, the switch includes a sw_ctrl pin, and the step 203 may include:

When it is determined that the first charging device is connected, generating a switching signal;

The switch signal is sent to the switch through the sw_ctrl pin, so that the switch switches to the first charging path.

In the embodiment of the present invention, a charging path for overcurrent during charging can be formed through the D+/D- pins (specifically, 4 pins, two on each side). When the charger 1 is not plugged in, the D+/D- pin of the mobile terminal female head is connected to the D+/D- pin of the USB phy. When it is detected that the charger 1 is plugged in, the processor controls the level of the sw-ctrl pin to switch the switch, and the D+/D- pin of the female head of the mobile terminal is connected to the Vbus pin to form a charging path, that is, the first charging path.

Step 204, when it is determined that a second charging device is connected, use the Vbus pin of the second charging path to charge the mobile terminal.

In a specific implementation, when the charger 2 is inserted into the Type-C adapter, the male head of the Type-C adapter and the CC2 pin of the female head of the Type-C adapter of the mobile terminal can detect the connection of the charger 2, so that it can Communicate with the processor and send the message of charger 2 to the processor. After the processor receives the above message, it can configure charging parameters with charger 1 through the RX+ pin and RX- pin, and charger 2 can be based on The 4 Vbus pins of the second charging path charge the mobile terminal.

It should be noted that, for the method embodiment, for the sake of simple description, it is expressed as a series of action combinations, but those skilled in the art should know that the embodiment of the present invention is not limited by the described action sequence, because According to the embodiment of the present invention, certain steps may be performed in other orders or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification belong to preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
