[0042] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] In conjunction with the accompanying drawings, a charging interface 100, an electronic device, and a control method and device thereof provided in an embodiment of the present application are described below through specific embodiments and application scenarios.

[0045] First, as Figure 1 and Figure 5 As shown, the present application provides a charging interface 100, including: a circuit board 110, on which a power supply pin 112 and a non-power supply pin 114 are arranged side by side; a shell 120, which is arranged on the circuit board 110, and at least part of the power supply pin 112 and the non-power supply pin 114 are located inside the shell 120; a short circuit detection component 130, which is arranged on the shell 120, and the short circuit detection component 130 is used to detect a short circuit between the power supply pin 112 and the non-power supply pin 114, and output a detection signal according to the short circuit between the power supply pin 112 and the non-power supply pin 114.

[0046] In an embodiment of the present application, the charging interface 100 includes a circuit board 110, a shell 120 and a short circuit detection component 130. The circuit board 110 has a power supply pin 112 and a non-power supply pin 114 arranged side by side. The power supply pin 112 can realize functions such as charging. The non-power supply pin 114 includes a ground pin, a data transmission pin, a configuration channel pin and a multiplexing pin, etc.

[0047] The shell 120 is set on the circuit board 110 to protect the circuit board 110. At least part of the power supply pin 112 and the non-power supply pin 114 are located inside the shell 120. The short circuit detection component 130 is set on the shell 120. The short circuit detection component 130 can detect the short circuit between the power supply pin 112 and the non-power supply pin 114. In addition, the short circuit detection component 130 can output a detection signal based on the short circuit between the power supply pin 112 and the non-power supply pin 114, so that the chip 220 of the electronic device can identify the detection signal and adopt a corresponding control strategy.

[0048] As mentioned above, the charging interface 100 provided in the present application has a short-circuit detection component 130 which can output a detection signal according to the short-circuit condition between the power supply pin 112 and the non-power supply pin 114, thereby adding a short-circuit feedback function to the charging interface 100, and reducing the possibility of failure of the charging interface 100 caused by a short circuit between the power supply pin 112 and the non-power supply pin 114.

[0049] Specifically, the charging interface 100 may be a Universal Serial Bus (USB), which includes Type-A, Type-B, and Type-C.

[0050] like Figure 1 and Figure 5 As shown, as a possible implementation, the short circuit detection component 130 includes: a flexible printed circuit 132 (FPC), which is attached to the housing 120, and the flexible printed circuit 132 is connected to the circuit board 110; a sensor 134, which is arranged on the flexible printed circuit 132 or the housing 120 and is connected to the flexible printed circuit 132, and at least part of the positive projection of the sensor 134 on the circuit board 110 falls on the power supply pin 112, and the sensor 134 is used to detect the short circuit between the power supply pin 112 and the non-power supply pin 114, and output a detection signal according to the short circuit between the power supply pin 112 and the non-power supply pin 114.

[0051] Specifically, the short circuit detection component 130 includes a flexible circuit board 132 and a sensor 134. The flexible circuit board 132 is attached to the shell 120. The flexible circuit board 132 is located outside the shell 120, and the flexible circuit board 132 is used to reduce the volume of the short circuit detection component 130. Moreover, since the flexible circuit board 132 is bendable, the flexible circuit board 132 can better fit the shell 120, thereby reducing the volume of the entire charging interface 100.

[0052] The sensor 134 is arranged on the flexible circuit board 132 or the shell 120. The flexible circuit board 132 connects the circuit board 110 and the sensor 134 to power the sensor 134 and transmit the detection signal emitted by the sensor 134 to the chip 220 and other components, so that the sensor 134 does not need to be powered independently, reducing the difficulty of installing the charging interface 100.

[0053] The flexible circuit board 132 may be connected to the power supply pin 112 , and the power supply pin 112 may be used to supply power to the sensor 134 , thereby reducing the difficulty of designing the circuit board 110 .

[0054] The flexible circuit board 132 can be connected to the power supply pin 112 of the circuit board 110 to supply power to the sensor 134 and lead out the detection signal output by the sensor 134 .

[0055] At least a portion of the positive projection of the sensor 134 on the circuit board 110 falls on the power supply pin 112 . The sensor 134 and the power supply pin 112 are aligned, so that the short-circuit current generated by the power supply pin 112 can be detected more accurately.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as a possible implementation, the sensor 134 is a Hall magnetic sensor, and the short-circuit detection component 130 also includes a magnetic component 136, which is arranged on the outside of the shell 120. The magnetic field of the magnetic component 136 acts on the magnetic field direction of the sensor 134, which is perpendicular to the current direction of the short-circuit current generated between the power supply pin 112 and the non-power supply pin 114.

[0057] Specifically, the sensor 134 is a Hall magnetic sensor, and the short-circuit detection component 130 also includes a magnetic part 136. The magnetic part 136 is arranged on the shell 120. The magnetic field of the magnetic part 136 acts on the sensor 134. The sensor 134 is arranged in the magnetic field of the magnetic part 136. When a short circuit occurs between the power supply pin 112 and the non-power supply pin 114, a short-circuit current is generated. The short-circuit current interferes with the magnetic field, so that the sensor 134 can output a detection signal according to the short circuit condition between the power supply pin 112 and the non-power supply pin 114.

[0058] Among them, the sensor 134 and the magnetic part 136 are both placed on the shell 120, and the sensor 134 is electrically connected to the circuit board 110 through the flexible circuit board 132. The flexible circuit board 132 and the sensor 134 can be attached to the shell 120, so as to realize the setting of the short circuit detection component 130 without adding additional pins on the circuit board 110. The flexible circuit board 132 can be welded and connected to the pins of the circuit board 110 to realize the power supply of the sensor 134 and the output of the detection signal, wherein the flexible circuit board 132 can be connected to the power supply pin 112.

[0059] Specifically, Figure 2 As shown, the direction of the current that can be detected by the sensor 134 is a direction that is perpendicular to the direction of the magnetic field applied by the magnetic member 136 to the sensor 134. The position of the magnetic member 136 can be adjusted appropriately as long as the direction of the magnetic field generated at the sensor 134 is perpendicular to the direction of the current detected by the sensor 134. The direction of the current detected by the sensor 134 is the current direction of the short-circuit current generated between the power supply pin 112 and the non-power supply pin 114. The sensor 134 can detect the horizontal current, which will eventually generate a voltage difference between the V+ interface and the V- interface. After being processed by the amplifier 210 and the analog-to-digital converter 222, the magnitude of the current can be characterized by the voltage, wherein the VCC interface of the sensor 134 is used for power supply, and the GND interface of the sensor 134 is used for grounding.

[0060] like Figure 3 As shown, when there is no short circuit between the power supply pin 112 and the non-power supply pin 114, the charging current enters from the power supply pin 112 and forms a loop through the non-power supply pin 114. When the charging current flows through the sensor 134, the current direction of the charging current is the same as the direction of the magnetic field, and the output detection signal does not change.

[0061] Specifically, the power supply pins correspond to A4 and A9, that is, the Vbus pin, and the non-power supply pins 114 correspond to A1, A3, A5, A8, A10 and A12, among which A1 and A12 are ground pins to form a power supply loop, corresponding to the GND pin, A3 and A10 are data transmission pins for USB3.0 signals, corresponding to TX1-pin and RX2-pin respectively, A5 is used to detect the positive and negative directions of the charger insertion, corresponding to the CC1 pin, and A8 is a multiplexed pin, corresponding to SBU1. The charging current enters the current management chip 220 (Power Management Integrated Circuit, PMIC) of the electronic device from A4, and then returns to A1 to form a complete charging current path. Similarly, the charging current enters the current management chip 220 of the electronic device from A9, and then returns to A12 to form a complete charging current path. Due to the placement of the magnetic part 136 and the sensor 134, the current direction of the charging current is perpendicular to the short-circuit current, which is consistent with the direction of the magnetic field, and the V+ interface and the V- interface will not change.

[0062] like Figure 4 As shown, in the case of a short circuit between the power supply pin 112 and the non-power supply pin 114, that is, after liquid or dust enters the charging interface 100, A4 and A1, A3, A5, A8, A9, A10 or A12 may be short-circuited, and similarly A9 and A1, A3, A4, A5, A8, A10 or A12 may be short-circuited, thereby generating a transverse short-circuit current, and the current direction of the short-circuit current is perpendicular to the direction of the magnetic field. The sensor 134 will generate an induced voltage, the V+ interface and the V- interface will change, and the detection signal will change, and then the electronic device can check the leakage current of the power supply pin 112, so that the electronic device can perform some operations such as reducing the charging power, prompting the user to clean the port, and stopping charging, so as to improve the safety of the electronic device and the durability of the charging interface 100.

[0063] Specifically, the sensor 134 is powered by the power supply pin 112. The detection signal output by the sensor 134 is amplified by the amplifier 210, sampled by the analog-to-digital converter 222 of the chip 220, and the detection signal is detected, and finally the short circuit condition of the power supply pin 112 and the non-power supply pin 114 can be determined.

[0064] like Figure 5 , Figure 6 and Figure 7 As shown, as a possible implementation, the sensor 134 is a Hall current sensor.

[0065] Specifically, the sensor 134 is a Hall current sensor, which can detect the direction and magnitude of the current, and output a detection signal when a short circuit occurs between the power supply pin 112 and the non-power supply pin 114 .

[0066] like Figure 6 As shown, the Hall current sensor has its own magnetic field inside, which can directly detect the current direction and intensity of the short-circuit current. The detected current direction is a transverse current, that is, perpendicular to the extension direction of the power supply pin 112. The sensor 134 can detect the transverse current, and finally a voltage difference will be generated between the V+ interface and the V- interface. After being processed by the amplifier 210 and the analog-to-digital converter 222, the magnitude of the current can be characterized by the voltage, wherein the VCC interface of the sensor 134 is used for power supply, and the GND interface of the sensor 134 is used for grounding.

[0067] like Figure 7 As shown, in the case of a short circuit between the power supply pin 112 and the non-power supply pin 114, that is, after liquid or dust enters the charging interface 100, A4 and A1, A3, A5, A8, A9, A10 or A12 may be short-circuited, and similarly A9 and A1, A3, A4, A5, A8, A10 or A12 may be short-circuited, thereby generating a transverse short-circuit current, and then the sensor 134 will generate an induced voltage, the V+ interface and the V- interface will change, and thus the detection signal will change, and then the electronic device can check the leakage current of the power supply pin 112, so that the electronic device can perform some operations such as reducing the charging power, prompting the user to clean the port, stopping charging, etc., so as to improve the safety of the electronic device and the durability of the charging interface 100.

[0068] Specifically, the power supply pin corresponds to A4 and A9, that is, the Vbus pin, and the non-power supply pin 114 corresponds to A1, A3, A5, A8, A10 and A12, among which A1 and A12 are ground pins to form a power supply loop, corresponding to the GND pin, A3 and A10 are data transmission pins for USB3.0 signals, corresponding to TX1-pin and RX2-pin respectively, A5 is used to detect the positive and negative directions of the charger insertion, corresponding to the CC1 pin, A8 is a multiplexed pin, corresponding to SBU1, and the sensor 134 is powered by the power supply pin 112. The detection signal output by the sensor 134 is amplified by the amplifier 210, sampled by the analog-to-digital converter 222 of the chip 220, and the detection signal is detected, and finally the short circuit condition of the power supply pin 112 and the non-power supply pin 114 can be determined.

[0069] like Figure 3 , Figure 4 and Figure 7As shown, as a possible implementation, there are at least two power supply pins 112 and non-power supply pins 114 , there is at least one non-power supply pin 114 between adjacent power supply pins 112 , there are two sensors 134 , and the sensors 134 and the power supply pins 112 correspond one to one.

[0070] Specifically, there are at least two power supply pins 112 and non-power supply pins 114, and there is at least one non-power supply pin 114 between adjacent power supply pins 112. The number of sensors 134 is two, and one sensor 134 corresponds to one power supply pin 112, so that each power supply pin 112 can detect a short circuit between it and the non-power supply pin 114.

[0071] Among them, Fig. 9 As shown, taking the Type-C charging interface 100 as an example, the charging interface 100 has a total of 12 pairs of pins, namely A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, B1, B 2, B 3, B 4, B 5, B 6, B7, B 8, B 9, B 10, B 11 and B12, wherein the power supply pin 112 corresponds to the pins A4, A9, B4 and B9, which correspond to Vbuspin, and a sensor 134 is set for each position of A4, A9, B4 and B9, and the non-power supply pin 114 corresponds to the pins A1, A2, A3, A5, A6, A7, A8, A10, A11, A12, B1, B 2, B 3, B 4, B 5, B 6, B 7, B 8, B 10, B 11 and B12. 11 and B12, among which A2, A3, B2, B3, A10, A11, B10 and B11 are the data transmission pins of USB3.0 signals, corresponding to TX1+pin, TX1-pin, TX2+pin, TX2-pin, RX2-pin, RX2+pin, RX1-pin and RX1+pin respectively; A5 and B5 are the configuration channel pins for detecting the positive and negative directions of the charger insertion, corresponding to CC1 pin and CC2 pin respectively; A6, A7, B6 and B7 are the data transmission pins of USB2.0 signals, corresponding to D+pin, D-pin, D+pin and D-pin respectively; A8 and B8 are multiplexed pins, corresponding to SBU1 pin and SBU2pin; A1, B1, A12 and B12 are ground pins to form a power supply loop, corresponding to GND pin.

[0072] In the case that A4, A5 and A6 are short-circuited by water droplets, the sensor 134 can detect and output a detection signal, thereby identifying the short-circuit between the power supply pin 112 and the non-power supply pin 114.

[0073] In a second aspect, the present application provides an electronic device, including: a charging interface as provided in the embodiment of the first aspect.

[0074] The electronic device provided in the present application includes the charging interface provided in the embodiment of the first aspect, and therefore has all the beneficial effects of the charging interface provided in the embodiment of the first aspect, which will not be stated one by one here.

[0075] like Figure 8 As shown, the electronic device includes an amplifier 210 and a chip 220. The chip 220 includes an analog-to-digital converter 222. The amplifier 210 is used to amplify the detection signal, and the fuzzy converter is used to convert the analog detection signal into a digital detection signal, so as to facilitate the analysis of the chip 220.

[0076] The chip 220 may be a system on chip (SoC).

[0077] Fig.10 FIG. 1 shows one of the flow charts of the control method of the electronic device according to an embodiment of the present application. Fig.10 As shown, the method includes:

[0078] Step 1002: Detect the working condition of the charging interface.

[0079] Specifically, the working condition of the charging interface is detected, that is, whether the charging interface is in a charging state is determined.

[0080] Step 1004: When the charging interface is charging, obtain a detection signal output by the short-circuit detection component.

[0081] Specifically, if the charging interface is charging, a detection signal output by the short-circuit detection component is obtained to determine the short-circuit condition of the power supply pin and the non-power supply pin of the charging interface.

[0082] Step 1006: Control the charging power of the electronic device according to the detection signal.

[0083] Specifically, the charging power of the electronic device is controlled according to the detection signal to avoid malfunction of the electronic device caused by charging when the power supply pin and the non-power supply pin of the charging interface are short-circuited.

[0084] In an embodiment of the present application, the status of the charging interface is monitored, and when the charging interface is charging, a detection signal output by the short-circuit detection component is obtained, and the detection signal is analyzed. According to the analysis result, the charging power of the electronic device is controlled, and then the charging power of the electronic device can be adjusted according to the short circuit between the power supply pin and the non-power supply pin, thereby reducing the possibility of electronic device failure caused by the short circuit between the power supply pin and the non-power supply pin.

[0085] As a possible implementation, the charging power of the electronic device is controlled according to the detection signal, including: when the strength of the detection signal is greater than a first threshold, controlling the charging power of the electronic device to be reduced to a power threshold; when the strength of the detection signal is greater than a second threshold, controlling the electronic device to stop charging so that the charging power of the electronic device is reduced to zero; wherein the first threshold is less than the second threshold.

[0086] Specifically, the charging power of the electronic device is controlled according to the detection signal, including: when the strength of the detection signal is greater than a first threshold, controlling the electronic device to reduce the charging power and charging at a power threshold, wherein the charging power can be reduced by reducing the charging voltage, reducing the charging current, or reducing both the charging power supply and the charging current.

[0087] When the intensity of the detection signal is greater than the second threshold, the electronic device is controlled to stop charging, so that the charging power of the electronic device is reduced to zero.

[0088] Among them, the first threshold is less than the second threshold, and the greater the strength of the detection signal, the more serious the short circuit between the power supply pin and the non-power supply pin. When the strength of the detection signal is greater than the first threshold, it means that the power supply pin and the non-power supply pin are in a short circuit state, and the short circuit is relatively light. In this case, the charging power is reduced to achieve charging in a safe manner; when the strength of the detection signal is greater than the second threshold, it means that the power supply pin and the non-power supply pin are in a short circuit state, and the short circuit is relatively serious. In this case, charging is stopped to ensure the safety of the electronic device.

[0089] That is, the first threshold is a threshold when the leakage current is low, and the second threshold is a threshold when the leakage current is high.

[0090] As a possible implementation, after controlling the electronic device to stop charging, the method further includes: controlling the electronic device to issue an abnormality reminder of the charging interface.

[0091] Specifically, after controlling the electronic device to stop charging, it also includes: controlling the screen, speaker, vibration motor or flash light and other components of the electronic device to operate to issue an abnormal reminder of the charging interface.

[0092] like Fig. 9 As shown, when charging is performed when there are water droplets or dust between the power supply pin and the non-power supply pin, the power supply pin will leak electricity, which will accelerate the corrosion and damage of the power supply pin and the non-power supply pin, and eventually lead to abnormal phenomena such as the charging port cannot be charged, the screen cannot be projected, or data cannot be transmitted.

[0093] Fig.11 FIG. 2 shows a second flow chart of a control method of an electronic device according to an embodiment of the present application. Fig.11 As shown, the method includes:

[0094] Step 1102: Determine whether the charging port is plugged into a charger;

[0095] Step 1104: obtaining a detection signal output by the short-circuit detection component;

[0096] Step 1106: whether the voltage of the detection signal is greater than a first threshold; if the voltage of the detection signal is greater than the first threshold, execute step 1108; if the voltage of the detection signal is not greater than the first threshold, execute step 1104;

[0097] Step 1108: reducing the charging power to a power threshold;

[0098] Step 1110: obtaining a detection signal output by the short-circuit detection component;

[0099] Step 1112: whether the voltage of the detection signal is greater than a second threshold; if the voltage of the detection signal is greater than the second threshold, execute step 1114; if the voltage of the detection signal is not greater than the second threshold, execute step 1104;

[0100] Step 1114: Stop charging and prompt the user that the charging is abnormal. Please check whether there is any foreign matter such as liquid or dust in the charging port.

[0101] This application checks the size of the leakage current and sets two thresholds. When the leakage current is small, the impact on the corrosion of the power supply pins and the non-power supply pins is small. In this case, the charging power can be reduced to ensure the charging function. When the leakage current is relatively large, the impact on the corrosion of the power supply pins and the non-power supply pins is large. In this case, the charging can be directly disconnected, and the user is prompted to check whether there is foreign matter such as liquid or dust entering the charging port, and please clean it in time, thereby improving the durability of the charging port.
