In the scenario that the external charging cable is connected with the first mobile device at the main interface and the other interface is connected with the second mobile device, the ID line of the external charging cable is at a low level, the first mobile device checks the level state of the ID line, and after determining that the ID line is at the low level (obtaining an indication message indicating the start of the external charging function), the external charging function is started, and the electric quantity of the external charging cable is transmitted to the second mobile device.
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
An embodiment of the present application provides a charging cable, and referring to fig. 3, the charging cable 300 may include:
a first interface 301 for connecting a first mobile device;
a second interface 302 for connecting a charging device capable of charging the first mobile device;
a third interface 303 for connecting a second mobile device capable of accepting charging of the first mobile device;
an internal charging power line 304, connected to the first interface 301 and the second interface 302, for the charging device to charge the first mobile device;
an external charging power line 305 is connected to the first interface 301 and the third interface 303, and is used for charging the second mobile device by the first mobile device.
In this way, when the first interface 301 and the second interface 302 of the charging cable 300 are connected to the first mobile device and the charging device, respectively, the charging device can charge the first mobile device through the charging cable 300; when the first interface 301 and the third interface 303 of the charging cable 300 are connected to the first mobile device and the second mobile device, respectively, the first mobile device can read the charging of the second mobile device through the charging cable 300. Therefore, through the charging cable 300, the charging device can be charged and can be realized that the first mobile device is charged and the second mobile device is charged, so that the internal charging and the external charging functions of the first mobile device are ensured, and in addition, the charging cable 300 can be used for simplifying the number of cables and is convenient to carry, so that the user experience can be improved.
The first implementation mode comprises the following steps: in order to implement power management for the first mobile device, optionally, the charging cable 300 may also generate an indication message instructing the first mobile device to start an internal charging function or an external charging function. Optionally, the charging cable 300 may generate the indication message according to a connection state of the second interface 302 and the third interface 303.
Optionally, in the first implementation manner, the charging cable 300 may determine the connection state of the second interface 302 and the third interface 303 according to the following manner:
the second interface 302 is further configured to generate a first connection message when the charging device is connected;
the third interface 303 is further configured to generate the second connection message when the second mobile device is connected.
As such, when the second interface 302 is generating the first connection message, it indicates that the second interface 302 has connected the charging device; when the third interface 303 is generating the second connection message, it indicates that the third interface 303 has connected the second mobile device.
Optionally, in the first implementation manner, when the charging cable 300 further includes an indication module 306, the charging cable 300 may generate the indication message by the indication module 306 by using the following method:
when the second interface 302 is connected to the charging device and the third interface 303 is not connected to the second mobile device, acquiring the first connection message, and determining a first indication message according to the first connection message, where the first indication message is used to indicate that the first mobile device accepts charging of the charging device; or
When the second interface 302 is not connected with the charging device and the third interface 303 is connected with the second mobile device, obtaining the second connection message, and determining a second indication message according to the second connection message, where the second indication message is used to indicate that the first mobile device charges the second mobile device; or
When the second interface 302 is connected to the charging device and the third interface 303 is connected to the second mobile device, the first connection message and the second connection message are obtained, and the first indication message or the second indication message is determined according to the first connection message and the second connection message.
Since the charging cable 300 has three interfaces, in practical application, there may be a scenario where the three interfaces of the charging cable 300 are connected to corresponding devices at the same time, that is, in this scenario, the first interface 301 is connected to the first mobile device, the second interface 302 is connected to the charging device, and the third interface 303 is connected to the second mobile device at the same time. In this scenario, if the first mobile device simultaneously implements the internal charging function and the external charging function, a safety problem such as device damage may be caused, and therefore, in the above method, when the indication module 306 simultaneously acquires the first connection message and the second connection message, the indication module 306 may generate an indication message, so that the first mobile device can only implement one function of internal charging or external charging, thereby improving the safety when the charging cable 300 is used for charging.
In a possible implementation, the indication module 306 may determine the indication message (i.e. the first indication message and the second indication message) according to the first connection message and/or the second connection message by setting an algorithm.
In a possible implementation, the first connection message is represented by a high level or a low level; the second connect message is represented by a high level or a low level.
In a possible implementation, the indication message may also be represented by a level, but it should be noted that the level representing the first indication message and the second indication message is different. That is, the first indication message is represented by a high level, and the second indication message is represented by a low level; or the first indication message is represented by a low level and the second indication message is represented by a high level.
When a connection message (i.e., the first connection message, the second connection message) and an indication message (i.e., the second indication message and the second indication message) are both represented by a level, the indication module 306 may implement the setting algorithm through a set logic operation device to determine the indication message.
For the same operation of the mobile device as the level status indication of the conventional ID line, i.e. the first indication message is represented by a high level "1" and the second indication message is represented by a low level "0". Referring to table 1, an embodiment of the present application provides a correspondence between a connection message and an indication message:
TABLE 1
As shown in fig. 3, in the first implementation manner, the first interface 303 is further configured to send the first indication message or the second indication message generated by the indication module 306 to the first mobile device when the first mobile device is connected.
In this way, the first mobile device may obtain the first indication message or the second indication message, perform corresponding operations, and implement an internal charging function or an external charging function.
Optionally, the charging cable 300 may further include a switch module 307 for controlling the on and off of the pair of internal charging power lines 304 and the pair of external charging power lines 305.
In a possible implementation, in order to avoid causing a safety problem in the above scenario, the switch module 307 may control only one of the pair of internal charging power lines 304 and the external charging power line 305 to be turned on, that is, the external charging power line 305 is turned off when the switch module 307 controls the pair of internal charging power lines 304 to be turned on; when the switch module 307 controls to turn on the external charging power line 305, the internal charging power supply 304 is turned off.
The second implementation mode comprises the following steps: the switch module 307 can control the connection and disconnection of the two power lines according to the connection message.
In this second implementation manner, the switch module 307 is specifically configured to:
referring to fig. 3, when the second interface generates the first connection message, the first connection message is acquired; when the third interface generates the second connection message, acquiring the second connection message;
after acquiring the first connection message, turning on the pair of internal charging power lines 304; or
After acquiring the second connection message, turning on the external charging power line 305; or
After acquiring the first connection message and the second connection message, the pair of internal charging power lines 304 and the pair of external charging power lines 305 are disconnected.
Referring to table 2, the embodiment of the present application provides a correspondence relationship between a connection message and a connection condition of two power lines:
TABLE 2
| First connection message | Second connection message | Internally charging power line | External charging power line |
| Is provided with | Is provided with | Disconnect | Disconnect |
| Is provided with | Is free of | Conduction of | Disconnect |
| Is free of | Is provided with | Disconnect | Conduction of |
| Is free of | Is free of | Off/on | Off/on |
Through the above method, the switch module 307 may control the connection and disconnection of the two power lines according to the connection state of the second interface 302 and the third interface 303, so as to implement the functions of charging the first mobile device inwards and outwards. In addition, after the switch module 307 acquires the first connection message and the second connection message, the two power lines are disconnected at the same time, so that the safety problem caused when the three interfaces of the charging cable 300 are connected with corresponding devices at the same time can be avoided, and the safety when the charging cable 300 is used for charging is improved.
The third implementation mode comprises the following steps: the switch module 307 can also control the connection and disconnection of the two power lines according to the indication message generated by the indication module 306.
In this third implementation, the switch module 307 is specifically configured to:
acquiring a first indication message or a second indication message generated by the indication module; and
after the first indication message is acquired, the pair of internal charging power lines are conducted; or
And after the second indication message is acquired, the external charging power line is conducted.
Referring to table 3, the embodiment of the present application further provides a corresponding relationship between an indication message and connection conditions of two power lines:
TABLE 3
| Indication message | Internally charging power line | External charging power line |
| First indication message | Conduction of | Disconnect |
| Second indication message | Disconnect | Conduction of |
| Is free of | On/off | On/off |
By the above method, the switch module 307 may control the on and off of the two power lines according to the operation performed by the first mobile device, so as to implement the internal charging and external charging functions of the first mobile device.
