[0003] With the increasing progress of electronic technology, various mobile electronic products are emerging in an endless stream. Especially with the maturity and popularity of wireless charging technology, charging methods and charging interfaces are becoming increasingly diversified.

These chargers often have wired power input ports, wired power output ports, and wireless charging coils.

[0028] Embodiment One

[0029] First, refer to FIG. 1, which is a schematic diagram of a circuit structure of a multifunctional charging device supporting bidirectional blind insertion according to an embodiment of the present application.

[0030] As shown in FIG. 1, the multifunctional charging device 100 supporting bidirectional blind insertion according to an embodiment of the present application includes a first bidirectional wired port 111, a second bidirectional wired port 112, a first insertion detection unit 131, a second insertion detection unit 132, a first switch unit 141, a second switch unit 142, a voltage control unit 150, a wireless charging unit 160, and a fast charging protocol control unit 120.

[0031] The first bidirectional wired port 111 is electrically connected to the voltage control unit 150 via a controlled terminal of the first switch unit 141, and the second bidirectional wired port 112 is electrically connected to the voltage control unit 150 via a controlled terminal of the second switch unit 142. The control terminal of the first switch unit 141 is electrically connected to the fast charging protocol control unit 120, and the control terminal of the second switch unit 142 is electrically connected to the fast charging protocol control unit 120. The fast charging protocol control unit 120 is further electrically connected to the first bidirectional wired port 111 via the first insertion detection unit 131, and the fast charging protocol control unit 120 is further electrically connected to the second bidirectional wired port 112 via the second insertion detection unit 132. The voltage control unit 150 is electrically connected to the fast charging protocol control unit 120 and the wireless charging unit 160.

[0032] The fast charging protocol control unit 120 detects the insertion state of the first bidirectional wired port 111 through the first insertion detection unit 131, and detects the insertion state of the second bidirectional wired port 112 through the second insertion detection unit 132. Moreover, the fast charging protocol control unit 120 outputs a control signal to the control end of the first switch unit 141 to control the access and disconnection of the first bidirectional wired port 111. The fast charging protocol control unit 120 outputs a control signal to the control end of the second switch unit 142 to control the access and disconnection of the second bidirectional wired port 112. The voltage control unit 150 can provide power supply for the fast charging protocol control unit 120 and the wireless charging unit 160. The fast charging protocol control unit can be realized by means of a single-chip microcomputer, a programmable logic device, etc. The first and second bidirectional wired ports can be USB-A, USB-C, etc. interfaces. It should be noted that although only the first and second bidirectional wired ports are shown in the figure, it is easy to know that a person skilled in the art can configure three and more bidirectional wired ports and the corresponding number of switch units and insertion detection units according to needs. The first and second insertion detection units can be realized by means of diodes, triodes, pull-down resistors, pull-up resistors, etc. to identify the type of external equipment inserted into the first and second bidirectional wired ports as a power supply device or a device to be charged, and transmit the signals obtained by detection to the fast charging protocol control unit. The first and second switch units can be triodes, thyristors, field effect transistors or relays. The voltage control unit can include one or more of the following voltage conversion circuits: Buck, Boost, Buck-Boost and LDO.

[0033] In some embodiments, the charging device 100 further comprises a first wired power output interface 191 and a second wired power output interface 192, which are in communication connection with the fast charging protocol control unit 120 and are electrically connected with the voltage control unit 150. The charging device 100 can supply power to the device to be charged through the first wired power output interface 191 and the second wired power output interface 192. In some possible embodiments, the first wired power output interface 191 and the second wired power output interface 192 can be one or more of the following interfaces: USB, DC Out, Lightning and MagSafe.

[0034] Figure 2 is a partial circuit diagram of a multifunctional charging device supporting bidirectional blind insertion according to an embodiment of the present application. As shown in Figure 2, the fast charging protocol control unit 120 includes a microprocessor U1, a first communication port of the microprocessor U1 is connected to first data pins (e.g. CC1 and CC2 pins) of the first bidirectional wired port 111 through a first bus 113, and a second communication port of the microprocessor U1 is connected to second data pins (e.g. CC1 and CC2 pins) of the second bidirectional wired port 112 through a second bus 114. The microprocessor U1 can communicate with the connected power supply device and the device to be charged through the first bus 113 and the second bus 114 to negotiate the fast charging protocol, obtain the supported charging voltage, current and power combination of the power supply device and the device to be charged, and select a charging voltage and a charging current compatible with both the power supply device and the device to be charged according to the supported charging voltage, current and power combination of the power supply device and the device to be charged, so that the power supply device and the device to be charged are charged at a safe charging voltage, thereby completing the negotiation of the fast charging protocol. The microprocessor can be implemented by using various types of single-chip microcomputers.

[0035] The first insertion detection unit 131 includes a first resistor R1 and a second resistor R2, which are connected in series between a first power supply pin (e.g. Vbus pin) of the first bidirectional wired port 111 and ground, and a common terminal of the first resistor R1 and the second resistor R2 is connected to a first voltage acquisition port of the microprocessor U1 (fast charging protocol control unit). The second insertion detection unit 132 includes a third resistor R3 and a fourth resistor R4, which are connected in series between a second power supply pin (e.g. Vbus pin) of the second bidirectional wired port 112 and ground, and a common terminal of the third resistor R3 and the fourth resistor R4 is connected to a second voltage acquisition port of the microprocessor U1 (fast charging protocol control unit). When an external power supply device is connected to the first or second bidirectional wired port, the output voltage of the power supply device will generate a signal at the first or second insertion detection unit. For example, when the power supply device is connected to the first bidirectional wired port 111, a high level is generated at the first power supply pin of the first bidirectional wired port 111, which generates a high level at the common terminal of the first resistor R1 and the second resistor R2 of the first insertion detection unit 131, and the microprocessor U1 can determine that the power supply device is connected to the first bidirectional wired port 111 after detecting the high level at the first voltage acquisition port.

[0036] The first switch unit 141 comprises a first triode Q1, a second triode Q2, a fifth resistor R5, a sixth resistor R6 and a seventh resistor R7, and the second switch unit 142 comprises a third triode Q3, a fourth triode Q4, an eighth resistor R8, a ninth resistor R9 and a tenth resistor R10. The first triode Q1 and the third triode Q3 are enhancement mode P-channel MOSFETs, and the second triode Q2 and the fourth triode Q4 are enhancement mode N-channel MOSFETs. The gate of the first triode Q1 is connected to the source of the second triode Q2 through the sixth resistor R6, the drain of the first triode Q1 is connected to the drain of the third triode Q3, the source of the first triode Q1 is connected to the first power pin of the first bidirectional wired port 111, the source of the third triode Q3 is connected to the second power pin of the second bidirectional wired port 112, the fifth resistor R5 is connected between the gate and the drain of the first triode Q1, the eighth resistor R8 is connected between the gate and the drain of the third triode Q3, the seventh resistor R7 is connected between the gate of the second triode Q2 and the ground, and the drain of the second triode Q2 is connected to the ground. The tenth resistor R10 is connected between the gate of the fourth triode Q4 and the ground, and the drain of the fourth triode Q4 is connected to the ground. The gate of the second triode Q2 is connected to the first output port of the microprocessor U1, and the gate of the fourth triode Q4 is connected to the second output port of the microprocessor U1. In the initial state, the first triode Q1 and the third triode Q3 are in the off state, so that the first switch unit 141 and the second switch unit 142 are in the off state. When the microprocessor U1 (fast charging protocol control unit) detects that the corresponding bidirectional wired port is connected to the power supply device through the first insertion detection unit 131 or the second insertion detection unit 132, the microprocessor U1 outputs a control signal through the first output port or the second output port to control the first switch unit 141 or the second switch unit 142 to be turned on, so that the external device is supplied with power through the turned-on switch unit. For example, when the power supply device is connected to the first bidirectional wired port 111, the microprocessor U1 sends a control signal to the gate of the second triode Q3 of the first switch unit 141 through the first output port, so that the second triode Q2 is turned on, and after the second triode Q2 is turned on, the gate of the first triode Q1 is grounded, so that the first triode Q1 is turned on. It is easy to understand that the first switch unit and the second switch unit can be in the off state in the initial state, so as to effectively isolate the external device connected to the first and second bidirectional wired ports, and avoid the situation that the device is damaged due to the voltage mismatch between the power supply device and the charging device.

[0037] Referring to FIG. 3, FIG. 3 is a schematic diagram of the circuit structure of the voltage control unit in FIG. 1. As shown, the voltage control unit 1 includes a voltage conversion circuit 151 and a step-down circuit 152. The voltage conversion circuit 151 is electrically connected to the wireless charging unit 160, the first bidirectional wired port 111 or the second bidirectional wired port 112, and obtains power from the first bidirectional wired port 111 or the second bidirectional wired port 112, converts the power into a suitable voltage to charge the device to be charged connected to the charging device 100. For example, when the first bidirectional wired port 111 is connected to a power supply device (e.g., a charger), the second bidirectional wired port 112 and the wireless charging unit 160 are connected to a smartphone, the voltage conversion circuit 151 obtains power provided by the charger from the first bidirectional wired port 111, and converts the power into a voltage suitable for charging the smartphone, thereby charging the smartphone. The voltage conversion circuit 151 can include various voltage conversion circuits, such as Buck, Boost, Buck-Boost, and LDO. The step-down circuit 152 obtains power from the voltage conversion circuit 151 and converts the power into a voltage suitable for powering the fast charging protocol control unit 120. The step-down circuit 152 can be a Buck circuit or an LDO circuit.

[0038] Meanwhile, the voltage conversion circuit 151 can also be electrically connected to the fast charging protocol control unit 120, and the output voltage of the voltage conversion circuit 151 is controlled by the fast charging protocol control unit 120, so as to generate a corresponding output voltage according to the fast charging protocol supported by the device to be charged.

[0039] In the present embodiment, the fast charging protocol control unit can detect whether the first and second bidirectional wired ports are connected to external electronic devices through the first and second insertion detection units, and determine whether the connected external electronic devices are power supply devices or devices to be charged, and then control the first or second switch unit to be turned on or off so as to select the corresponding external device as a power source to supply power to the circuit. The user can arbitrarily insert a power supply device and a device to be charged into the first or second bidirectional wired port, and the charging device can supply power to the devices to be charged connected to the first or second bidirectional wired port, the wireless charging unit, and the first and second wired power supply output interfaces simultaneously or separately. For example, the user can insert a power supply device into the first bidirectional wired port, and simultaneously connect multiple devices to be charged to the wireless charging unit, the second bidirectional wired port, and the first and second wired power supply output interfaces, so as to charge the multiple devices to be charged simultaneously. Moreover, the fast charging protocol control unit negotiates the input power with the power supply device through the fast charging protocol, and negotiates the output power with the output device, so as to realize the effect of normal fast charging and wireless charging of the charging device when the power supply device and the device to be charged are arbitrarily inserted into the first and second bidirectional wired ports, thereby supporting the functions of bidirectional blind insertion and fast charging while supporting wired and wireless charging.

The fast charging protocol control unit 220 outputs a control signal to the control end of the second switch unit 242 to control the access and disconnection of the second bidirectional wired port 212.

Then, the fast charging protocol control unit controls the first or second switch unit to be turned on or off so as to select the corresponding external device as a power supply to supply power to the circuit. The user can insert the power supply device and the device to be charged into the first or second bidirectional wired port at will, and the charging device can supply power to the device to be charged connected to the first or second bidirectional wired port, the wireless charging unit, and the first and second wired power supply output interfaces at the same time or separately. For example, the user can insert the power supply device into the first bidirectional wired port, and connect multiple devices to be charged to the wireless charging unit, the second bidirectional wired port, and the first and second wired power supply output interfaces respectively, so as to charge the multiple devices to be charged at the same time. The fast charging protocol control unit negotiates the input power with the power supply device through the fast charging protocol, and negotiates the output power with the output device, so that the charging device can normally realize fast charging and wireless charging when the power supply device and the device to be charged are inserted into the first and second bidirectional wired ports at will. Thus, the charging device supports wired and wireless charging, and supports bidirectional blind insertion and fast charging at the same time.
