[0050] It should be understood that the exemplary embodiments described herein are only used to explain this application and are not used to limit this application.

[0051] In subsequent descriptions, suffixes such as "module", "component", or "unit" used to represent elements are only for the convenience of explaining this application and have no specific meaning in themselves. Therefore, "module", "component", or "unit" can be used interchangeably.

The touch panel 1071 can include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the touch orientation of the user, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, and / or converts it into contact coordinates, and then sends it to the processor 110, and can receive and execute the commands sent by the processor 110.

In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

Subsequently, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in Figure 1 the touch panel 1071 and the display panel 1061 are implemented as two independent components to realize the input and output functions of the smart terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to realize the input and output functions of the smart terminal, and no limitation is made here.

[0065] The memory 109 can be used to store software programs and various data. The memory 109 mainly includes a program storage area and a data storage area. Optionally, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created according to the use of the mobile phone (such as audio data, phone book, etc.). In addition, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0066] The processor 110 is the control center of the intelligent terminal, connecting various parts of the entire intelligent terminal through various interfaces and circuits. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it executes various functions of the intelligent terminal and processes data, thereby monitoring the intelligent terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It can be understood that the above-mentioned modem processor may not be integrated into the processor 110 either.

[0067] The intelligent terminal 100 may also include a power supply 111 (such as a battery) for supplying power to each component. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, so as to realize functions such as management of charging, discharging, and power consumption management through the power management system.

[0068] Although Figure 1 not shown, the intelligent terminal 100 may also include a Bluetooth module, etc., which will not be elaborated here.

[0114] Third Embodiment

[0115] The charging device further includes an isolation circuit. The first end of the isolation circuit is connected to the charging interface, the second end of the isolation circuit is connected to the wired charging circuit, and the third end of the isolation circuit is connected to the wireless reverse charging circuit.

[0116] As Figure 4 shown, Figure 4 FIG. is a schematic diagram of the pins of a charging interface provided by an embodiment of the present application. There are two pins on the charging interface, namely pin 1 and pin 2. Some adapters or smart terminals only connect to one of pin 1 and pin 2, causing the other pin to be in a floating state. This charging interface is a single-sided TypeC. Both the wireless reverse charging chip and the wired charging chip need to be connected to the charging interface through pins to draw power after performing fast charging protocol adaptation on the adapter. Wired reverse charging also needs to perform fast charging protocol adaptation with the receiving end through the pins of the charging interface and then supply power. However, the signals are all connected to the charging interface, which may cause signal interference and inaccurate signals, and further lead to protocol adaptation failure and inability to charge.

[0117] As Figure 5 shown, Figure 5 FIG. is a schematic diagram of the structure of an isolation circuit provided by an embodiment of the present application. The isolation circuit includes a first switching tube and a second switching tube. The first end of the first switching tube is connected to the charging interface, the second end of the first switching tube is connected to the wireless reverse charging chip and the first end of the second switching tube, and the second end of the second switching tube is connected to the wired charging chip. The control ends of the first switching tube and the second switching tube are connected to the controller, and the controller is used to control the on and off of the first switching tube and the second switching tube. The wireless reverse charging circuit can be integrated in the wireless reverse charging chip, and the wired charging circuit can be integrated in the wired charging chip. In other words, the wireless reverse charging chip includes the wireless reverse charging circuit to implement the wireless reverse charging function of the charging device; the wired charging chip includes the wired charging circuit to implement the wired charging function of the charging device.

[0118] Optionally, the first switching tube and the second switching tube are MOSFET switching tubes.

[0119] Optionally, the wireless reverse charging chip and the wired charging chip are respectively connected to the battery of the charging device through different power management modules.

[0120] Optionally, according to the detected charging interface status, the controller controls the conduction and cutoff of the first switch tube and the second switch tube to implement the switching between the wireless reverse charging and wired charging functions. If it is detected that a wired charging device is connected (for example, there is a voltage signal at the charging interface), the controller turns on the second switch tube to connect the wired charging chip to the charging interface, and at the same time turns off the first switch tube to ensure the isolation of the wireless reverse charging chip from the charging interface. If it is detected that no wired charging device is connected, the controller turns on the first switch tube to connect the wireless reverse charging chip to the charging interface, and at the same time turns off the second switch tube to ensure the isolation of the wired charging chip from the charging interface. The controller can dynamically control the conduction and cutoff of the first switch tube and the second switch tube according to the status of the charging interface, thereby realizing the isolation and switching of the wireless reverse charging and wired charging functions. This method not only improves the charging efficiency but also enhances the safety and reliability of the system. As Figure 6 shown, Figure 6 FIG. 8 is a schematic structural diagram of another isolation circuit provided by an embodiment of the present application. The isolation circuit includes four single-pole double-throw switch chips, which are respectively connected to pin 1 and pin 2 of the charging interface. The output of switch chip 4 is connected to the GPIO pin of the wireless reverse charging chip, and the output of switch chip 2 is connected to the CC_A pin of the wired charging chip through the CC_TX pin.

[0121] In this embodiment, by switching the high and low levels of pin CP1 or pin CP3, pin 1 or pin 2 of the charging interface is respectively connected to the circuit, and the detection of the single-sided TypeC interface is realized.

[0122] During wired charging or wired reverse charging: when CP2 is at a low level, switch chip 1 is connected to port A of switch chip 2 through CC1 (pin 1) or CC2 (pin 2), and then connected to the wired charging chip through the CC_A pin; at the same time, when CP4 is at a high level, the GPIO pin is connected to the CC_TX pin, realizing the floating setting of the wireless reverse charging chip, thereby realizing the isolation of the wireless reverse charging chip from the wired charging and discharging.

[0123] During wireless reverse charging with adapter power supply: when CP2 is at a high level, the CC_A pin is connected to the CC_TX pin, and the wired charging chip is in a floating state; when CP4 is at a low level, it is realized that CC1 or CC2 is connected to the GPIO pin through switch chip 3, realizing the connection with the wireless reverse charging chip.

[0124] When powered by battery for wireless reverse charging: CP2 is at high level, the CC_A pin is connected to the CC_TX pin, CP4 is at high level, the GPIO pin is connected to the CC_TX pin, and the CC pins of the wired charging chip and the wireless charging chip are connected. At this time, the wireless reverse charging chip can control the wired charging chip to achieve reverse charging power supply, so that the battery can supply power to the wireless reverse charging circuit through the wired reverse charging circuit. At this time, the Y output pins of switch chip 1 and switch chip 3 are in a floating state, and pins 1 and 2 of the TypeC interface are in a floating state for the system, so as to realize the isolation between the adapter and the wireless reverse charging chip and the wired reverse charging chip.
