DETAILED DESCRIPTION

[0057] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0058] At present, the electronic device is provided with a plurality of first conductive terminals, and the charging base is provided with a plurality of second conductive terminals. When the first conductive terminal of the electronic device is connected to the second conductive terminal of the charging base and the charging base is connected to the charging device or other electronic devices, the charging device can charge the electronic device through the first conductive terminal, and other electronic devices can transmit data, audio and video, etc. with the electronic device through the first conductive terminal. The electronic device usually includes two first conductive terminals or four first conductive terminals. When the electronic device includes two first conductive terminals, the first conductive terminals are respectively the first power terminal and the first ground terminal. When the electronic device includes four first conductive terminals, the first conductive terminals are respectively the first power terminal, the first ground terminal, the first data terminal and the second data terminal. The charging base usually includes two second conductive terminals or four second conductive terminals. When the charging base includes two second conductive terminals, the second conductive terminals are respectively the second power terminal and the second ground terminal. When the charging base includes four second conductive terminals, the second conductive terminals are respectively the second power terminal, the second ground terminal, the third data terminal and the fourth data terminal. For different manufacturers, the arrangement order of the first conductive terminals in the electronic device and the arrangement order of the second conductive terminals in the charging base may be different, and the number of the first conductive terminals in the electronic device and the number of the second conductive terminals in the charging base may be different, and the electronic device and the charging base may be incompatible. Figure 1As shown, the electronic device 400 includes four first conductive terminals, which are the first ground terminal GND1, the first data terminal D1+, the second data terminal D1- and the first power terminal VBUS1 in order. The charging base 500 includes two second conductive terminals, which are the second ground terminal GND2 and the second power terminal VBUS2 in order. When the electronic device 400 is connected to the charging base 500, the first data terminal D1+ is connected to the second power terminal VBUS2, and the second data terminal D1- is connected to the second ground terminal GND2. Since the voltage of the second power terminal VBUS2 is high and the data terminal of the main control circuit of the electronic device 400 is input through the first data terminal D1+, the main control circuit in the electronic device 400 is damaged. In addition, since the first conductive terminal and the second conductive terminal are set in a different order, the electronic device 400 cannot be charged through the charging base 500.

[0059] In the related art, in order to enable a charging base to be used for charging electronic devices, an electronic device is provided. Figure 2 As shown, the electronic device 400 includes four first conductive terminals, which are the second data terminal D1-, the first power terminal VBUS1, the first ground terminal GND1 and the first data terminal D1+ in order. When the electronic device 400 is connected to the charging base 500, the first power terminal VBUS1 is connected to the second power terminal VBUS2, and the first ground terminal GND1 is connected to the second ground terminal GND2. When the charging base 500 is correctly connected to the electronic device 400, the electronic device 400 can be charged. However, when the electronic device 400 is misaligned with the charging base 500, the voltage of the second power terminal VBUS2 may be input into the electronic device 400 through the first data terminal D1+, the first ground terminal GND1 or the second data terminal D1-, resulting in the risk of damage to the electronic device 400.

[0060] Based on this, the present disclosure provides a control circuit, in which a switch circuit is used to control the on-off between the first charging terminal and the main control circuit, and / or the on-off between the first functional terminal and the main control circuit. When the electronic device is misaligned with the charging base, the switch circuit can control the disconnection between the first charging terminal and / or the first functional terminal and the main control circuit, preventing the voltage of the second charging terminal from being input into the main control circuit through the first functional terminal to avoid damage to the electronic device.

[0061] like Figure 3As shown, an exemplary embodiment of the present disclosure provides a control circuit, including a plurality of first conductive terminals 10, a main control circuit 20 and a switch circuit 30. The plurality of first conductive terminals 10 include a first charging terminal 11 and a first functional terminal 12. The first charging terminal 11 is used to connect to the second charging terminal of the charging base, and the first functional terminal 12 is used to connect to the second functional terminal of the charging base. The switch circuit 30 can be coupled between the first charging terminal 11 and the main control circuit 20 and between the first functional terminal 12 and the main control circuit 20, and is used to control the on-off between the first charging terminal 11 and the main control circuit 20 and the on-off between the first functional terminal 12 and the main control circuit 20. Alternatively, the switch circuit 30 can also be coupled only between the first charging terminal 11 and the main control circuit 20, and is used to control the on-off between the first charging terminal 11 and the main control circuit 20. Alternatively, the switch circuit 30 can also be coupled only between the first functional terminal 12 and the main control circuit 20, and is used to control the on-off between the first functional terminal 12 and the main control circuit 20. Among them, the first charging terminal 11 includes a first power terminal and a first ground terminal, and the first functional terminal 12 includes a first data terminal, a second data terminal, etc. The second charging terminal includes a second power terminal and a second ground terminal, and the second functional terminal includes a third data terminal, a fourth data terminal, etc. When the charging base includes a second charging terminal and a second functional terminal, the charging base can be used to charge the electronic device, and to transmit data, audio and video, etc. with the electronic device. When the charging base only includes the second charging terminal, the charging base can only be used to charge the electronic device.

[0062] In this embodiment, the control circuit of the electronic device includes a plurality of first conductive terminals, a main control circuit and a switch circuit, and the switch circuit is coupled between the first charging terminal and the main control circuit and / or between the first functional terminal and the main control circuit. The switch circuit is used to control the on-off between the first charging terminal and the main control circuit, and / or the on-off between the first functional terminal and the main control circuit, so that the voltage of the first charging terminal and the first functional terminal is input into the main control circuit or prevent the voltage of the first charging terminal and the first functional terminal from being input into the main control circuit. Since the switch circuit can control the on-off between the first charging terminal and / or the first functional terminal and the main control circuit, when the electronic device is misaligned with the charging base, the voltage of the second charging terminal can be prevented from being input into the main control circuit through the first functional terminal, thereby preventing damage to the electronic device.

[0063] In one embodiment, if Figure 4As shown, the switch circuit 30 includes a first switch circuit 31. The first end of the first switch circuit 31 is coupled to the first ground terminal GND1 in the first charging terminal 11, the second end is used to couple to the ground terminal GND, and the third end is used to couple to the power supply VDD, and is used to control the on-off between the first ground terminal GND1 and the ground terminal GND according to the voltage of the first ground terminal GND1 and the power supply VDD. Among them, the power supply terminal VCC of the main control circuit 20 is used to couple to the power supply VDD, the common terminal VSS is used to couple to the ground terminal GND, the first data terminal D+ is coupled to the first data terminal D1+ in the first function terminal 12, and the second data terminal D- is coupled to the second data terminal D1- in the first function terminal 12. The first power terminal VBUS1 in the first charging terminal 11 may not be used to control the first switch circuit 31.

[0064] When the second power terminal of the charging base is connected to the first ground terminal GND1, and the second ground terminal is connected to the first functional terminal 12, the voltage of the first functional terminal 12 relative to the first ground terminal GND1 is negative. Because in the electronic device, there is a certain voltage correlation between the first functional terminal 12 and the power supply VDD. When the voltage of the first functional terminal 12 relative to the first ground terminal GND1 is negative, the voltage of the power supply VDD relative to the first ground terminal GND1 is negative, and the absolute value of the voltage is less than the absolute value of the voltage of the first functional terminal 12 relative to the first ground terminal GND1. At this time, if the first ground terminal GND1 and the ground terminal GND are turned on, the current flows in through the common terminal VSS of the main control circuit 20, flows out from the first data terminal D+ and / or the power supply terminal VCC, or, flows out from the second data terminal D- and / or the power supply terminal VCC. Among them, the second ground terminal of the charging base is connected to the first functional terminal 12, which can be coupled to the first data terminal D1+ or the second data terminal D1-, which is not limited here.

[0065] In this embodiment, the switch circuit includes a first switch circuit, and two ends of the first switch circuit are respectively coupled to the first ground terminal and the ground terminal. Since the first switch circuit can determine whether the control circuit introduces negative voltage due to the misalignment of the connection of the charging base according to the voltage of the power supply and the first ground terminal. When the control circuit introduces negative voltage, the first switch circuit can disconnect the first ground terminal from the ground terminal to prevent current from flowing from the ground terminal into the main control circuit, thereby preventing damage to the electronic device.

[0066] It is understandable that the power supply terminal VCC of the main control circuit 20 can also be coupled to other power supplies in the electronic device, which is not limited here. In addition to including the first data terminal D1+ and the second data terminal D1-, the first functional terminal 12 can also include terminals for implementing functions such as audio and video transmission, which is not limited here. When the second power terminal is connected to the first ground terminal GND1, in addition to introducing negative voltage through the first data terminal D1+ or the second data terminal D1-, negative voltage may also be introduced from terminals in the first functional terminal 12 such as audio and video transmission, which is not limited here.

[0067] In one embodiment, if Figure 5 As shown, the fourth terminal of the first switch circuit 31 is coupled to the first control terminal C1 of the main control circuit 20, and is also used to control the connection between the first ground terminal GND1 and the ground terminal GND according to the signal received from the first control terminal C1.

[0068] In this embodiment, the fourth terminal of the first switch circuit is coupled to the first control terminal of the main control circuit, and the main control circuit can control the first switch circuit through the first control terminal to connect or disconnect the first ground terminal to the ground terminal as needed. Since the first switch circuit can be controlled to connect or disconnect the first ground terminal to the ground terminal, the controllability of the first switch circuit is increased, thereby improving the reliability of the control circuit.

[0069] Exemplarily, the control circuit further includes a first diode VD1 and a first resistor R1. The anode of the first diode VD1 is coupled to the first control terminal C1 of the main control circuit 20, and the cathode is coupled to the fourth terminal of the first switch circuit 31. The first end of the first resistor R1 is used to couple to the ground terminal GND, and the second end is coupled between the cathode of the first diode VD1 and the fourth terminal of the first switch circuit 31. Through the first diode VD1, it is possible to prevent the current from flowing back from the fourth terminal of the first switch unit 31 to the first control terminal C1 of the main control circuit 20, thereby avoiding damage to the main control circuit 20. Through the first resistor R1, when the voltage of the first control terminal C1 of the main control circuit 20 is uncertain, the voltage of the fourth terminal of the first switch circuit 31 can be pulled down to the voltage of the ground terminal GND to avoid the first ground terminal GND1 from being disconnected from the ground terminal GND by mistake.

[0070] In one embodiment, if Figure 6As shown, the switch circuit 30 includes a second switch circuit 32. The first end of the second switch circuit 32 is coupled to the first data terminal D1+ in the first functional terminal 12, the second end is coupled to the second data terminal D1- in the first functional terminal 12, the third end is coupled to the first data terminal D+ of the main control circuit 20, the fourth end is coupled to the second data terminal D- of the main control circuit 20, and the fifth end is coupled to the second control terminal C2 of the main control circuit 20, and is used to control the connection and disconnection between the first data terminal D1+ and the first data terminal D+ of the main control circuit 20, and the connection and disconnection between the second data terminal D1- and the second data terminal D- of the main control circuit 20 according to the received signal of the second control terminal C2. Among them, the first ground terminal GND1 is coupled to the ground terminal GND.

[0071] When the second power terminal of the charging base is connected to the first data terminal D1+ or the second data terminal D1- in the first functional terminal 12, and the second ground terminal is connected to the first power terminal VBUS1, the voltage of the first functional terminal 12 relative to the first power terminal VBUS1 is positive and the voltage is relatively high. Since there is a certain voltage correlation between the first functional terminal 12 and the power supply VDD in the electronic device, the voltage of the power supply VDD relative to the first ground terminal GND1 becomes larger. At this time, the first data terminal D+ or the second data terminal D- of the main control circuit 20 may be damaged due to the increased voltage. Among them, the second power terminal of the charging base is connected to the first functional terminal 12, and in addition to being connected to the first data terminal D1+ or the second data terminal D1-, it can also be connected to the terminal of the first functional terminal 12 such as audio and video transmission, which is not limited here. When the second power terminal is connected to the terminal of the first functional terminal 12 such as audio and video transmission, the second switch circuit 32 also needs to be connected to the corresponding functional terminal in the main control circuit 20 to realize the conduction and disconnection between the first functional terminal and the functional terminal.

[0072] In this embodiment, the switch circuit includes a second switch circuit, and the two sides of the second switch circuit are respectively coupled to the first functional terminal and the main control circuit. The second switch circuit can control the on-off between the first data terminal and the first data terminal of the main control circuit, and the on-off between the second data terminal and the second data terminal of the main control circuit. When the electronic device is misaligned with the charging base, the second switch circuit can disconnect the first data terminal from the first data terminal and the second data terminal from the second data terminal under the control of the main control circuit, thereby preventing damage to the electronic device.

[0073] For example, Figure 7As shown, the control circuit also includes a second diode VD2 and a second resistor R2. The anode of the second diode VD2 is coupled to the second control terminal C2 of the main control circuit 20, and the cathode is coupled to the fifth terminal of the second switch circuit 32. The first end of the second resistor R2 is coupled to the first ground terminal GND1, and the second end is coupled between the cathode of the second diode VD2 and the fifth terminal of the second switch circuit 32. Through the second diode VD2, it is possible to prevent the current from flowing back from the fifth terminal of the second switch unit 32 to the second control terminal C2 of the main control circuit 20, thereby avoiding damage to the main control circuit 20. Through the second resistor R2, when the voltage of the second control terminal C2 of the main control circuit 20 is uncertain, the voltage of the fifth terminal of the second switch circuit 32 can be pulled down to the voltage of the first ground terminal GND1 to avoid misconnection between the first data terminal D1+ and the first data terminal D+ of the main control circuit 20, and misconnection between the second data terminal D1- and the second data terminal D- of the main control circuit 20.

[0074] In one embodiment, if Figure 8 As shown, the control circuit also includes a charging circuit 40. The first end of the charging circuit 40 is coupled to the first power terminal VBUS1 in the first charging terminal 11, and the second end is coupled to the third control terminal C3 of the main control circuit 20, and is used to send a signal to the third control terminal C3 according to the voltage of the first power terminal VBUS1 to control the second switch circuit 32. The charging circuit 40 is also used to charge the battery in the electronic device. Among them, the first end of the charging circuit 40 is used to detect the voltage of the first power terminal VBUS1, and the second end is used to send a signal to the third control terminal C3 of the main control circuit 20 to control the second switch circuit 32.

[0075] In this embodiment, the charging circuit can detect the voltage of the first power terminal, and determine whether the charging base is connected incorrectly according to the voltage of the first power terminal. Since the charging circuit can determine whether the charging base is connected incorrectly, the second switch circuit is controlled by the main control circuit to avoid damage to the main control circuit to prevent damage to the electronic device. At the same time, since the voltage detection function of the charging circuit is reused, the complexity of the control circuit structure is reduced.

[0076] Exemplarily, the control circuit also includes an overvoltage protection circuit 50. The first end of the overvoltage protection circuit 50 is coupled to the first power terminal VBUS1, and the second end is coupled to the third end of the charging circuit 40, and is used to disconnect when the voltage of the first power terminal VBUS1 is higher than the voltage upper limit for overvoltage protection, and to turn on when the voltage of the first power terminal VBUS1 is lower than the voltage upper limit to charge the battery of the electronic device through the charging circuit 40. The first end of the overvoltage protection circuit 50 can be used to detect the voltage of the first power terminal VBUS1. The third end of the overvoltage protection circuit 50 can be coupled to the fourth end of the charging circuit 40, and is turned on or off by the control of the fourth end of the charging circuit 40. Among them, the value range of the voltage upper limit can be 5.5V~7V.

[0077] Exemplarily, when the switch circuit 30 includes only the first switch circuit 31, the control circuit may include a charging circuit 40 and an overvoltage protection circuit 50. The charging circuit 40 may send a signal to the third control terminal C3 according to the voltage of the first power terminal VBUS1 to control the first switch circuit 31.

[0078] In one embodiment, the control circuit further includes a communication circuit 60. The first data terminal D+ of the communication circuit 60 is coupled to the sixth terminal of the second switch circuit 32, and the second data terminal D- is coupled to the seventh terminal of the second switch circuit 32. The second switch circuit 32 is also used to control the connection and disconnection between the first data terminal D+ of the communication circuit 60 and the first data terminal D+ of the main control circuit 20, and the connection and disconnection between the second data terminal D- of the communication circuit 60 and the second data terminal D- of the main control circuit 20 according to the signal of the second control terminal C2. When the second switch circuit 32 controls the main control circuit 20 to be disconnected from the first functional terminal 12, the main control circuit 20 and the communication circuit 60 can be controlled to be connected. When the second switch circuit 32 controls the main control circuit 20 to be connected to the first functional terminal 12, the main control circuit 20 and the communication circuit 60 can be controlled to be disconnected.

[0079] In this embodiment, through the communication circuit, the electronic device can independently perform functions such as phone calls and message transmission and reception with other electronic devices, thereby improving the functionality of the electronic device. Since the second switch circuit can control the on / off between the communication circuit and the main control circuit under the control of the main control circuit, the independent communication can be stopped during the charging process of the electronic device, thereby improving the reliability of the control circuit. At the same time, since the second switch circuit can selectively connect the main control circuit with the first functional terminal and the communication circuit at the same time, data transmission confusion is avoided, thereby further improving the reliability of the control circuit.

[0080] Exemplarily, the eighth terminal of the second switch circuit 32 is used to couple with the power supply VDD, and the ninth terminal is coupled with the first ground terminal GND1, and the eighth terminal and the ninth terminal of the second switch circuit 32 are used to power the second switch circuit 32.

Since the first switch circuit can determine whether the control circuit introduces negative pressure due to the misalignment of the connection of the charging base according to the voltage of the power supply and the first ground terminal. The second switch circuit can control the on-off between the first data terminal and the first data terminal of the main control circuit, and the on-off between the second data terminal and the second data terminal of the main control circuit according to the voltage of the first power terminal detected by the charging circuit. When the electronic device is misaligned with the charging base, the first switch circuit can disconnect the first ground terminal from the ground terminal to prevent current from flowing from the ground terminal into the main control circuit, thereby preventing damage to the electronic device. The second switch circuit can disconnect the first data terminal from the first data terminal and the second data terminal from the second data terminal under the control of the main control circuit, thereby preventing damage to the electronic device. Through the dual protection of the first switch circuit and the second switch circuit, the first charging terminal and the first function terminal can be completely isolated from the main control circuit when the electronic device is misaligned with the charging base, thereby improving the reliability of the control circuit.

The first data terminal D+ of the main control circuit 20 is connected to the first data terminal D1+ and the second data terminal D- is connected to the second data terminal D1-, and the first ground terminal GND1 is connected to the ground terminal GND, so that data transmission can be performed.

[0085] In one embodiment, if Fig.10As shown, there are two states of switches in the first switch circuit 31 and the second switch circuit 32.

[0086] An exemplary embodiment of the present disclosure further provides a control method for a control circuit, which can be applied to the above-mentioned circuit structure, and the control method for a control circuit includes:

[0087] When the electronic device where the control circuit is located is connected to the charging base, if it is determined that the electronic device and the charging base are misaligned, the first charging terminal is controlled to be disconnected from the main control circuit.

[0088] In this embodiment, after the electronic device is connected to the charging base, it is determined whether the electronic device and the charging base are misaligned to determine whether to isolate the main control circuit. If it is determined that the electronic device and the charging base are misaligned, the first charging terminal is controlled to be disconnected from the main control circuit to isolate the main control circuit from the first charging terminal. Since the main control circuit is isolated from the first charging terminal when the charging base is misaligned, negative voltage is prevented from being introduced into the control circuit and the voltage of the second charging terminal is input into the main control circuit through the first functional terminal, thereby preventing damage to the electronic device.

[0089] An exemplary embodiment of the present disclosure further provides a control method for a control circuit, the control method for a control circuit comprising:

[0090] When the electronic device where the control circuit is located is connected to the charging base, if it is determined that the electronic device and the charging base are misaligned, the first functional terminal is controlled to be disconnected from the main control circuit.

[0091] In this embodiment, after the electronic device is connected to the charging base, it is determined whether the electronic device and the charging base are misaligned to determine whether to isolate the main control circuit. If it is determined that the electronic device and the charging base are misaligned, the first functional terminal is controlled to be disconnected from the main control circuit to isolate the main control circuit from the first functional terminal. Since the main control circuit is isolated from the first functional terminal when the charging base is misaligned, the voltage of the second charging terminal is prevented from being input into the main control circuit through the first functional terminal, thereby preventing damage to the electronic device.

[0092] An exemplary embodiment of the present disclosure further provides a control method for a control circuit, the control method for a control circuit comprising:

[0093] When the electronic device where the control circuit is located is connected to the charging base, if it is determined that the electronic device and the charging base are misaligned, the first charging terminal is controlled to be disconnected from the main control circuit and the first functional terminal is disconnected from the main control circuit.

[0094] In this embodiment, after the electronic device is connected to the charging base, it is determined whether the electronic device and the charging base are misaligned to determine whether to isolate the main control circuit. If it is determined that the electronic device and the charging base are misaligned, the first charging terminal is controlled to be disconnected from the main control circuit and the first functional terminal is controlled to be disconnected from the main control circuit, and the main control circuit is isolated from the first charging terminal and the first functional terminal. Since the main control circuit is isolated from the first charging terminal and the first functional terminal when the charging base is misaligned, negative voltage is prevented from being introduced into the control circuit and the voltage of the second charging terminal is prevented from being input into the main control circuit through the first functional terminal, thereby preventing damage to the electronic device. At the same time, by controlling the first charging terminal to be disconnected from the main control circuit and the first functional terminal to be disconnected from the main control circuit, damage to the electronic device is avoided in a double protection manner, thereby improving the reliability of the control circuit.

[0095] In one embodiment, the step of determining that the electronic device is misaligned with the charging base includes:

[0096] When the voltage of the power supply is less than the voltage of the first ground terminal, it is determined that the electronic device is misconnected to the charging base.

[0097] In this embodiment, when the voltage of the power supply is less than the voltage of the first ground terminal, the second power terminal is connected to the first ground terminal and the second ground terminal is connected to the first functional terminal, and it is determined that the electronic device is misaligned with the charging base. By determining whether negative pressure is introduced into the control circuit based on the magnitude relationship between the voltage of the power supply and the voltage of the first ground terminal, the complexity of the control circuit is reduced.

[0098] In one embodiment, the step of controlling the first charging terminal to be disconnected from the main control circuit includes:

[0099] The first ground terminal is controlled to be disconnected from the ground terminal.

[0100] In this embodiment, when it is determined that the electronic device and the charging base are misaligned because the second power terminal is connected to the first ground terminal and the second ground terminal is connected to the first functional terminal, the first ground terminal needs to be isolated from the ground terminal to prevent negative voltage from being introduced into the control circuit. By controlling the first ground terminal to be disconnected from the ground terminal, negative voltage is prevented from being introduced into the control circuit and the voltage of the second charging terminal is prevented from being input into the main control circuit through the first functional terminal, thereby preventing damage to the electronic device.

[0101] In one embodiment, the step of determining that the electronic device is misaligned with the charging base includes:

[0102] When the voltage of the first charging terminal is less than the voltage threshold or the voltage of the first charging terminal is not detected, it is determined that the electronic device is misconnected to the charging base.

[0103] In this embodiment, when the voltage of the first charging terminal is less than the voltage threshold, the second power terminal is connected to the first functional terminal and the second ground terminal is connected to the first power terminal, and it is determined that the electronic device is misaligned with the charging base. When the voltage of the first charging terminal is not detected, only one second conductive terminal in the charging base is connected to one of the first conductive terminals, and it is determined that the electronic device is misaligned with the charging base. By determining whether the electronic device is misaligned with the charging base based on the voltage of the first charging terminal, the complexity of the control circuit is reduced.

[0104] In one embodiment, the step of controlling the first functional terminal to be disconnected from the main control circuit includes:

[0105] The first data terminal is controlled to be disconnected from the first data terminal of the main control circuit.

[0106] The second data terminal is controlled to be disconnected from the second data terminal of the main control circuit.

[0107] In this embodiment, when the voltage of the power supply is less than the voltage of the first ground terminal, the first functional terminal needs to be isolated from the main control circuit to eliminate the harm caused by the negative pressure. Alternatively, when the second power terminal is connected to the first functional terminal and the second ground terminal is connected to the first power terminal, or only one second conductive terminal is connected to one of the first conductive terminals, the first functional terminal needs to be isolated from the main control circuit. Since the second charging terminal is connected to the first data terminal or the second data terminal in the first functional terminal, the first data terminal in the first functional terminal is controlled to be disconnected from the first data terminal of the main control circuit, and the second data terminal in the first functional terminal is controlled to be disconnected from the second data terminal of the main control circuit. By controlling the first data terminal and the second data terminal in the first functional terminal to be disconnected from the first data terminal and the second data terminal of the main control circuit, it is prevented that the voltage of the second charging terminal is input into the main control circuit through the first functional terminal or a larger voltage is introduced into the first data terminal and the second data terminal of the main control circuit, thereby preventing damage to the electronic device.

[0108] In one embodiment, the above step of controlling the first functional terminal to be disconnected from the main control circuit further includes:

[0109] The first data terminal of the control communication circuit is connected to the first data terminal of the main control circuit.

[0110] The second data terminal of the control communication circuit is connected to the second data terminal of the main control circuit.

[0111] In this embodiment, when the voltage of the power supply is less than the voltage of the first ground terminal, the first functional terminal needs to be disconnected from the main control circuit, and the first functional terminal is not needed to implement the data transmission function. Alternatively, when the second power terminal is connected to the first functional terminal and the second ground terminal is connected to the first power terminal, or only one second conductive terminal is connected to one of the first conductive terminals, the first functional terminal is not needed to implement the data transmission function. Since the second power terminal is connected to the first data terminal or the second data terminal in the first functional terminal, the first data terminal of the control communication circuit is connected to the first data terminal of the main control circuit, and the second data terminal of the control communication circuit is connected to the second data terminal of the main control circuit. By controlling the first data terminal and the second data terminal of the communication circuit to be connected to the first data terminal and the second data terminal of the main control circuit, the communication circuit can be put into operation to implement the communication function, thereby improving the reliability of the control of the control circuit.

[0112] In one embodiment, if it is determined that the electronic device is misaligned with the charging base, the control method of the control circuit further includes:

[0113] Issue misalignment prompt message.

[0114] In this embodiment, when the electronic device is misaligned with the charging base, misalignment prompt information is issued to prompt the user to avoid the electronic device being unable to charge or the voltage of the second charging terminal causing damage to the electronic device, thereby improving the reliability of the control circuit control.

[0115] Exemplarily, the sending of the misalignment prompt information can be achieved by displaying on a screen of the electronic device, alarming with a speaker of the electronic device, or by a main control circuit of the electronic device sending the information to other electronic devices of the user.

[0116] In one embodiment, the step of issuing misalignment prompt information includes:

[0117] When the voltage of the power supply is lower than the voltage of the first ground terminal, a first prompt message is issued.

[0118] When the voltage of the first charging terminal is less than the voltage threshold or the voltage of the first charging terminal is not detected, a second prompt message is issued.

[0119] In this embodiment, when the voltage of the power supply is less than the voltage of the first ground terminal, negative voltage is introduced into the control circuit, which may damage the main control circuit, and a first prompt message is issued to remind the user of a connection error. When the voltage of the first charging terminal is less than the voltage threshold or the voltage of the first charging terminal is not detected, the control circuit cannot identify the connection error mode, and a second prompt message is issued to remind the user that charging is not performed. By issuing different prompt messages to remind the user in different connection misalignment situations, the reliability of the control circuit is improved.

[0120] For example, when the voltage of the first charging terminal is less than the voltage threshold or the voltage of the first charging terminal is not detected, no prompt information may be issued. After the user connects the electronic device to the charging base, if no charging information is displayed, it can be directly determined that the connection is misaligned.

[0121] In one embodiment, when the electronic device where the control circuit is located is connected to the charging base, the control method of the control circuit further includes:

[0122] If it is determined that the electronic device is correctly connected to the charging base, the first charging terminal is controlled to be connected to the main control circuit and the first functional terminal is controlled to be connected to the main control circuit.

[0123] In this embodiment, if it is determined that the electronic device is correctly connected to the charging base, the electronic device can be charged through the charging base and the corresponding function can be realized. The first charging terminal and the first functional terminal are controlled to be connected to the main control circuit, the electronic device is charged and the corresponding function is realized, thereby improving the reliability of the control circuit.

[0124] Exemplarily, when the switch circuit is only coupled between the first charging terminal and the main control circuit, if it is determined that the electronic device is correctly connected to the charging base, the first charging terminal is controlled to be connected to the main control circuit, and the first functional terminal is connected to the main control circuit by default without control. When the switch circuit is only coupled between the first functional terminal and the main control circuit, if it is determined that the electronic device is correctly connected to the charging base, the first functional terminal is controlled to be connected to the main control circuit, and the first charging terminal is connected to the main control circuit by default without control.

[0125] In one embodiment, the above steps of determining that the electronic device is correctly connected to the charging base include:

[0126] When the voltage of the first charging terminal is greater than or equal to the voltage threshold, it is determined that the electronic device is correctly connected to the charging base.

[0127] In this embodiment, when the voltage of the first charging terminal is greater than or equal to the voltage threshold, the electronic device can be charged through the charging base without causing damage to the electronic device. By determining whether the electronic device is correctly connected to the charging base based on the voltage of the first charging terminal, the complexity of the control circuit is reduced.

[0128] In one embodiment, the above steps of controlling both the first charging terminal and the first functional terminal to be connected to the main control circuit include:

[0129] The first ground terminal is controlled to be connected to the ground terminal.

[0130] The first data terminal is controlled to be connected to the first data terminal of the main control circuit.

[0131] The second data terminal is controlled to be connected to the second data terminal of the main control circuit.

[0132] In this embodiment, by connecting the first ground terminal to the ground terminal, the charging base can be used to charge the electronic device. By controlling the first data terminal and the second data terminal in the first function terminal to be connected to the first data terminal and the second data terminal of the main control circuit, the main control circuit can transmit data with the charging base. When the electronic device is correctly connected to the charging base, the electronic device is charged and data is transmitted, thereby improving the reliability of the control circuit control.

[0133] In one embodiment, the above steps of controlling the first charging terminal and the first functional terminal to be connected to the main control circuit further include:

[0134] The first data terminal of the control communication circuit is disconnected from the first data terminal of the main control circuit.

[0135] The second data terminal of the control communication circuit is disconnected from the second data terminal of the main control circuit.

[0136] In this embodiment, since only one of the second switch circuits can be turned on at the same time, the communication circuit is disconnected from the main control circuit to ensure data transmission between the main control circuit and the charging base. By disconnecting the communication circuit from the main control circuit, interference caused by simultaneous data transmission between the communication circuit and the charging base is avoided, thereby improving the reliability of the control circuit.

[0137] In one embodiment, if it is determined that the electronic device is correctly connected to the charging base, the control method of the control circuit further includes:

[0138] Send a charging reminder message.

[0139] In this embodiment, when the electronic device is correctly connected to the charging base, a charging prompt message is sent to prompt the user, thereby improving the reliability of the control circuit control.

[0140] Exemplarily, the sending of the charging reminder information can be achieved by displaying on a screen of the electronic device, alarming with a speaker of the electronic device, or the main control circuit of the electronic device sending the information to other electronic devices of the user.
