In one example, as shown in fig. 3, a first mechanical switch 31 is provided inside the charging wire, and the ground pin 21 of the first connector is electrically connected to the first ID pin 22 of the first connector through the first mechanical switch 31. The user can make this first mechanical switch 31 closed through operating this first mechanical switch 31, makes this first ID pin 22 ground connection of charging wire for the first connector of charging wire possesses the function that triggers the mobile device to provide the electric energy.
A user can turn on the first mechanical switch 31 by operating the first mechanical switch 31, so that the first ID pin 22 is suspended, and when the charging wire is connected to the mobile device, the mobile device is a slave device and does not provide electric energy, and the charging wire can be used as a common connecting wire. For example, when the first connector of the charging line is connected to the mobile device and the second connector is connected to a USB (Universal Serial Bus) interface of the computer, the computer can charge the mobile device through the charging line, and can perform data transmission with the mobile device through the charging line. For another example, when the first connector of the charging cord is connected to the mobile device and the second connector is connected to a charger of the mobile device, the mobile device may be charged by the charger.
In one example, the charging wire is provided with an MCU, the MCU is connected with a control end of an electronic switch, and a grounding pin of the first connector is connected with a first ID pin of the first connector through the electronic switch. When this electron switch was closed, this first ID pin ground connection of charging wire for the first connector of charging wire possesses the function that triggers the mobile device and provide the electric energy. When the electronic switch is turned on, the charging wire can be used as a common connecting wire.
And when the MCU receives a switching signal or a switching instruction, the electronic switch is controlled to be switched between an open state and a closed state. The switching signal may be a signal generated when the switching key on the charging line is performed a predetermined operation, for example, the switching key may be a key such as a pressure key, a touch screen, a touch key, or the like; the switching instruction may be sent by the mobile device or the device to be charged.
For example, the switching key arranged on the charging line is used as a pressure key, and the predetermined operation is used as a pressing pressure key, when the electronic switch is in an on state, the MCU controls the electronic switch to be turned off when receiving an operation signal generated when the pressure key is pressed.
For another example, an application program for managing the charging line is installed on the mobile device, and the switching button is displayed in the application program. When detecting that the switching button is triggered, the mobile device sends a switching instruction to the MCU in the charging wire, and the MCU controls the electronic switch to switch between the on state and the off state according to the switching instruction.
Optionally, a physical key for triggering the MCU in the device to be charged to send a switching instruction to the MCU in the charging line may be provided on the device to be charged. Optionally, the device to be charged may further include a display screen, and an icon or a virtual button corresponding to the switching instruction may be displayed in the display screen; when the MCU in the charging equipment detects that the icon or the virtual button corresponding to the switching instruction is triggered, the MCU sends the switching instruction to the MCU in the charging line, and the MCU controls the electronic switch to be switched between the on state and the off state according to the switching instruction.
In one example, a second mechanical switch is disposed between the voltage output of the energy storage unit and the second power pin of the second connector. The user can control whether the energy storage unit supplies power to the equipment to be charged through the second connector or not by operating the second mechanical switch. Specifically, when the second mechanical switch is turned off, the energy storage unit can charge the device to be charged; when the second mechanical switch is turned on, the energy storage unit cannot charge the equipment to be charged;
in one example, a third mechanical switch is provided between the voltage input of the energy storage unit and the first power supply pin of the first connector of the charging line. The mobile device can charge the energy storage unit under the condition that the third mechanical switch is closed and the first connector is connected with the interface of the mobile device.
In one example, a changeover switch is provided in the charging line for alternatively connecting one of the voltage input of the energy storage unit and the second power supply pin of the second connector with the first power supply pin of the first connector. Therefore, a user can select whether to charge the energy storage unit or the device to be charged connected with the energy storage unit by operating the switch.
Alternatively, as shown in fig. 4, the second mechanical switch 41 is arranged inside the charging line on the transmission line 42 between the voltage output terminal of the energy storage unit and the second power supply pin of the second connector. The second mechanical switch 41 is connected to a retractable contact 43, part of the retractable contact 43 being located inside the charging cord, another part of the retractable contact 43 being located outside the charging cord, the other part being located beside the first connector 44.
When the first connector 44 is connected to the mobile device, the retractable contact 43 is pressed by the mobile device, and the retractable contact retracts into the housing of the charging cable, so as to drive the second mechanical switch 41 to be turned on, and the energy storage unit does not charge the device to be charged.
Optionally, a blocking structure 45 and an elastic structure 46 are further arranged in the charging cord. The resilient structure 46 is connected to the blocking structure 45 at one end and to the retractable contact 43 at the other end. Under the condition that the first connector 45 is suspended, the retractable contact 43 is not pressed, the blocking structure 45 and the elastic structure 46 provide thrust to the retractable contact 43, so that the retractable contact 43 extends out of the housing of the charging wire, and the second mechanical switch 41 is driven to be closed, so that the energy storage unit to-be-charged device is charged.
In one example, when the remaining capacity of the energy storage unit is lower than a preset first threshold, the MCU in the charging line sends a first indication message to the device to be charged or the mobile device connected thereto, where the first indication message is used to indicate that the energy storage unit needs to be charged. And the mobile equipment receiving the first indication message displays or broadcasts the first indication message in a voice mode. The device to be charged, which receives the first indication message, may also display or voice-broadcast the first indication message. So that the user operates the change-over switch or the third mechanical switch to charge the device to be charged by the mobile device.
In one example, when the device to be charged is fully charged, the device to be charged may provide a second indication message indicating that the device to be charged is fully charged. So that the user operates the change-over switch or the third mechanical switch to enable the mobile device to charge the energy storage unit.
The device to be charged can provide the indication message in the following ways:
first, a power indicator is provided on the device to be charged, and the power indicator is turned on when the device to be charged is charged. Optionally, the power indicator lights are lit when the device to be charged is charged and have a predetermined color, and the predetermined color may be red or green.
Secondly, the device to be charged displays or plays second indication information, and the second indication information may include at least one of characters and icons.
In one example, when the energy storage unit is fully charged, the MCU in the charging line transmits a third indication message to the device to be charged or the mobile device connected thereto, where the third indication message is used to indicate that the energy storage unit is fully charged. And the equipment to be charged or the mobile equipment displays or broadcasts the third indication message so that the user can operate the change-over switch according to the third indication message to stop the mobile equipment from charging the energy storage unit and the equipment to be charged.
In one example, the MCU in the charging line controls the on-off of the first circuit and/or the second circuit and/or the third circuit according to the reference electric quantity information.
The reference electric quantity information comprises at least one of the residual electric quantity of the equipment to be charged, the residual electric quantity of the energy storage unit and the residual electric quantity of the mobile equipment; the first circuit is a circuit between the voltage input end of the energy storage unit and the first power pin of the first connector, the second circuit is a circuit between the voltage output end of the energy storage unit and the second power pin of the second connector, and the third circuit is a circuit between the first power pin of the first connector and the second power pin of the second connector.
Specifically, an electronic switch can be respectively arranged in the first circuit, the second circuit and the third circuit, and the control end of each electronic switch is connected with the MCU in the charging wire.
For example, in the case that the remaining capacity of the device to be charged is lower than the preset second threshold, the energy storage unit does not need to be charged, and the first circuit is controlled to be open. For example, the second threshold may be 30%.
For another example, when the remaining power of the device to be charged is lower than the preset third threshold, in order to ensure that the mobile device operates normally, the MCU in the charging line controls the first circuit and the third circuit to be open circuits, so that the mobile device stops supplying power to the device to be charged and the energy storage unit. Furthermore, the MCU in the charging wire can control the second circuit to be a channel at the moment, so that the energy storage unit charges the device to be charged.
For another example, when the remaining capacity of the energy storage unit is lower than the preset fourth threshold, the MCU in the charging line may control the second circuit to be an open circuit, so that the energy storage unit stops charging the device to be charged. Furthermore, the MCU in the charging line can also control the first circuit to be a path, so that the mobile device can charge the energy storage unit.
For another example, when the remaining power of the device to be charged is higher than the fifth threshold (for example, 50%), and the remaining power of the device to be charged is lower than the preset third threshold, to ensure that the mobile device operates normally, the MCU in the charging line controls the first circuit and the third circuit to be open circuits, so that the mobile device stops supplying power to the device to be charged and the energy storage unit.
The MCU in the charging line can control the on-off of the first circuit and/or the second circuit and/or the third circuit according to the reference electric quantity information and a plurality of preset rules, wherein each preset rule comprises a preset condition and a preset operation. When reference electric quantity information acquired by the MCU in the charging wire meets a preset condition in a certain preset rule, the MCU executes a preset operation in the preset rule, and the preset operation comprises controlling the on-off of the first circuit and/or the second circuit and/or the third circuit. The preset rule may be set by a developer, or may be set by a user in an application program on the mobile device, or may be set by the user on the device to be charged. After receiving preset rules sent by the mobile device and/or the device to be charged, the MCU in the charging line stores the preset rules in a memory in the charging line.
In one example, in the case that the first connector is floating, the MCU in the charging line controls the second circuit to be a path, and the second circuit is a circuit between the voltage output terminal of the energy storage unit and the second power pin of the second connector. That is, in the case that the first connector on the charging line is not connected to the mobile device, the device to be charged is charged by the energy storage unit in the charging line at this time.
The MCU in the charging line can judge whether the first connector is suspended or not through the following modes.
First, be provided with pressure sensor on the first connector, this pressure sensor is connected with MCU in the charging wire. When the pressure value reported by the pressure sensor to the MCU in the charging wire is greater than a preset pressure threshold value, judging that the first connector is not suspended; and when the pressure value reported by the pressure sensor to the MCU in the charging wire is less than or equal to the pressure threshold value, determining that the first connector is suspended. Alternatively, the pressure threshold may be 0.
Secondly, detecting a resistance value between two pins preset in the first connector; when the resistance value is smaller than or equal to a preset resistance value threshold value, the first connector is judged not to be suspended; and when the resistance value is larger than a preset resistance value threshold value, determining that the first connector is suspended.
It should be noted that, a technician may preset that any two pins in the first connector are connected to the resistance detection component, and the resistance detection component may periodically detect the resistance value between the two pins; when the voltage input connector is not connected with the mobile device, the resistance value between the two preset pins is infinite. Therefore, when the resistance value is larger than the preset resistance threshold value, the first connector can be judged to be suspended.
