Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a control method and an electronic device. Background Technology

[0002] As is well known, mechanical switching devices use contacts to break circuits, such as plugs and sockets, adapter connectors of electronic devices, and connection ports of devices. When breaking a circuit in the atmosphere, if the voltage exceeds 12-20V and the current exceeds 0.25-1A, a nearly cylindrical gas with extremely high temperature, strong light, and conductivity is usually generated in the contact gap; this is an electric arc. The electric arc that occurs in switching devices is simply called a switching arc. An electric arc is a high-temperature, highly conductive ionized gas that delays circuit shutdown and has a significant destructive effect on the contacts.

[0003] Taking a laptop's Type-C charger as an example, when the charger is unplugged from the laptop during use, the voltage difference between the laptop's Type-C port and the charger's connector pins is about 20V. Therefore, an electric arc will be generated between the connectors. The larger the interrupted current, the larger the arc and the stronger the destructive power. Over time, it may even cause the pins to melt due to arcing, resulting in damage to the charger or laptop. Summary of the Invention

[0041] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0042] like Figure 1 As shown in the figure, this application discloses a control method for an electronic device. The electronic device has a battery and a charging port. The charging port is used to connect an external adapter to obtain electrical energy. A target circuit is provided between the battery and the charging port. A switching component is provided on the target circuit. The method includes:

[0043] S100: If the charging port is connected to the adapter, the control switch assembly closes;

[0044] S200: If the charging port is disconnected from the adapter, the control switch assembly is disconnected after a target time period, so that the battery's electrical energy can be delivered to the charging port through the target circuit within the target time period, thereby ensuring that the voltage difference between the charging port and the adapter connector meets the target threshold.

[0045] For example, the electronic device is a laptop or other device that can be connected to an external power source. This electronic device has an internal battery, which can be a lithium battery, a rechargeable battery, etc. The electronic device also has a charging port for connecting an external adapter to obtain power. The power through the charging port directly powers the entire electronic device or charges the battery. The circuits for powering the device and charging the battery are different and different from the target circuit of this embodiment. In this embodiment, a target circuit is provided between the charging port and the battery, and this target circuit has a switching component. This switching component is controlled by the electronic device or its system to open or close. Specifically, if the system detects that an adapter is connected to the charging port, it controls the switching component to close. For example, if the system detects that the target electrical signal level of the charging port is high, it can determine that an adapter is connected. If the system detects that the charging port is disconnected from the adapter, for example, if the system detects that the target electrical signal level of the charging port is low, it can determine that the adapter is disconnected. When the system determines that the two are disconnected, it controls the switching component to open after a target time period delay. That is, the system determines that the disconnection of the charging port and the adapter is the starting point, and controls the switching component to close after a target time period delay. When the switch assembly is closed, the target circuit is conductive but has no voltage, meaning no current flows through it, or a small current flows through it, resulting in a low voltage at the charging port. This allows for a faster voltage increase at the charging port when it is disconnected from the adapter, saving time. By delaying the disconnection of the switch assembly when the charging port is disconnected from the adapter, the battery's energy can be released through the target circuit, increasing the charging port voltage and preventing the voltage at the charging port from being too low compared to the adapter connector, which could cause a large voltage difference, generate arcing, and affect device safety. Disconnecting the switch assembly prevents energy waste caused by the battery releasing energy and flowing through the target circuit when the electronic device is powered by the battery.

[0046] Based on the disclosure of the above embodiments, it can be understood that the beneficial effects of this embodiment include adding a target circuit between the charging port and the battery, and setting a switching component on the circuit. Based on this, the system can control the on / off state of the switching component according to whether the charging port is connected to the adapter, that is, control whether the target circuit is on or off. Thus, when the adapter connector is disconnected from the charging port, the battery's electrical energy can be released based on the target circuit, thereby increasing the voltage of the charging port, reducing the voltage difference between the charging port and the adapter connector, avoiding the generation of switching arcs, and protecting the safety of the charging port and the adapter.

[0047] Furthermore, such as Figure 2As shown, the switching assembly in this embodiment includes a first switch, which is controlled by an electronic device to close or delay opening. The first switch can be an electronic switch, controlled by the electronic device system. The specific target time period for delaying opening is not fixed; it can be 0.5s, 1s, or even 1.5s, but it should not be too long, as an excessively long time can easily cause energy loss due to the target circuit when the battery releases power.

[0048] For example, if the adapter's input voltage is approximately 20V, and the charging port voltage is 0V under normal conditions when the adapter connector is disconnected, the voltage difference between the adapter connector and the charging port will be approximately 20V, which is greater than the target threshold of 12V (this value is variable and may vary depending on the actual situation). This can easily lead to arcing. However, by introducing the method of this embodiment, the first switch is activated when the adapter is connected to the charging port, and when the adapter connector is disconnected from the charging port, the system controls the first switch to deactivate after a delay of approximately 0.5 seconds. This allows the battery's energy to be released and transferred to the charging port, increasing its voltage, such as to 12V. This makes the voltage difference between the port voltage and the adapter connector approximately 20V - 12V (battery voltage) 8V, which is less than 12V. Therefore, this effectively avoids the generation of switching arcs, ensuring the safety of the device, while also preventing the waste of battery energy.

[0049] Furthermore, the switch assembly in this embodiment also includes a second switch, which is a switching transistor. The second switch adapter connector is disconnected from the charging port and automatically turned on.

[0050] For example, the second switch is a diode, which is installed in the target circuit. When the adapter is connected to the charging port and the first switch is closed, the port voltage is greater than the battery voltage, and the diode is in a non-conductive state. When the adapter is disconnected from the charging port, the first switch remains closed for the target time period after disconnection. At this time, the battery voltage is higher than the port voltage, the diode is turned on, and the battery energy is released, the port voltage rises to the battery voltage, ensuring that the voltage difference between the port voltage and the adapter connector voltage is less than the target threshold, and no switching arc is generated. This target threshold is equivalent to the minimum voltage at which a switching arc is generated. This minimum voltage may fluctuate under different environments, so the target threshold can be adjusted accordingly. This adjustment can be manual or automatic by the device. For example, the system stores target thresholds for different environments. The system can obtain environmental parameters through detectors, determine the current environment based on the environmental parameters, and finally determine a matching target threshold based on the environment to help ensure that no switching arc is generated.

[0051] Furthermore, the target threshold was adjusted. To ensure that no switching arcing occurs, the port voltage when the adapter is unplugged also needs to be adjusted. Even with a constant target threshold, different batteries produce different voltages. To ensure that the voltage difference between the port voltage and the connector voltage does not generate an arc when the adapter connector is unplugged from the charging port, the battery voltage also needs to be adaptively adjusted.

[0052] Specifically, such as Figure 2 As shown, the target circuit in this embodiment is also equipped with a voltage regulator;

[0053] like Figure 3 As shown, the method in this embodiment further includes:

[0054] S300: Determine the voltage difference between the charging port and the battery, at least when the adapter is connected to the charging port;

[0055] S400: At least based on a differential pressure control voltage regulator, the battery voltage is adjusted so that the differential pressure between the charging port and the adapter connector meets a target threshold when the charging port is disconnected from the adapter connector.

[0056] For example, such as Figure 2 As shown, the structure of a voltage regulator can be formed by combining diodes, switches, capacitors, and other components, or it can be formed by other structures. The specific structure is not unique, as long as it can achieve the effect of adjusting the voltage. In application, when the adapter is connected to the charging port, the voltage difference between the charging port and the battery can be determined, that is, the voltage difference between the adapter voltage and the battery voltage. Then, based on this voltage difference and a target threshold or other preset threshold, it can be determined whether the battery voltage needs to be adjusted. For example, if the battery voltage is low, causing the voltage difference between it and the port voltage to be too large, exceeding the target threshold, then it indicates that a switching arc will occur when the adapter is disconnected from the charging port. In this case, the voltage difference needs to be reduced. The method to reduce the voltage difference is to adjust the battery output voltage, such as increasing the output voltage, so that the electrical energy passing through the target circuit is increased after being adjusted by the voltage regulator. This, in turn, increases the port voltage value when the adapter is disconnected from the charging port, ultimately effectively reducing the voltage difference between it and the adapter connector voltage, preventing the generation of a switching arc. In other words, the system in this embodiment can determine whether the battery voltage needs to be adjusted based on the voltage difference between the actual output voltage of the battery and the voltage of the charging port when the adapter is connected to the charging port. If adjustment is needed, the voltage regulator is controlled to adjust the electrical energy released by the battery to the target circuit, thereby adjusting the port voltage when the adapter is disconnected from the charging port, effectively avoiding the generation of switching arcs.

[0057] Specifically, in this embodiment, the control voltage regulator adjusts the battery voltage based at least on the voltage difference, including:

[0058] S401: The voltage regulator adjusts the battery voltage based on differential pressure and differential pressure threshold.

[0059] In other words, the system control voltage regulator adjusts the battery voltage based on the voltage difference between the adapter and the charging port when the adapter is unplugged and a preset voltage difference threshold. This adjustment can be done by increasing the voltage value, decreasing the voltage value, or keeping the voltage value unchanged.

[0060] Specifically, in this embodiment, adjusting the battery voltage based on the voltage difference and voltage difference threshold control voltage regulator includes:

[0061] S402: If the differential pressure is within the differential pressure threshold, increase the battery voltage;

[0062] If the differential pressure is greater than the differential pressure threshold, the battery voltage is maintained.

[0063] For example, the system can control the voltage regulator to compare the measured voltage difference with a preset voltage difference threshold. If the voltage difference is within the threshold, it indicates that the battery voltage needs to be increased to increase the voltage at the charging port. Alternatively, the system can control the voltage regulator to compare the measured voltage difference with the preset voltage difference threshold. If the voltage difference is greater than the threshold, it indicates that the current voltage difference can ensure that no switching arc will occur, and the voltage does not need to be adjusted. That is, the system can control the voltage regulator to perform the above-mentioned judgment and adjustment operations. Alternatively, the system can compare the measured voltage difference with the preset voltage difference threshold and directly control the voltage regulator to adjust the battery output voltage based on the judgment result. In this embodiment, the voltage difference threshold can be matched with a target threshold so that the voltage difference threshold can match the actual voltage difference that will cause a switching arc. This ensures that through the judgment and calibration of the voltage difference threshold, the difference between the adjusted battery output voltage and the connector voltage when the adapter is unplugged will not trigger the generation of a switching arc.

[0064] The specific adjustment value can be matched and adjusted according to the actual pressure difference. Specifically, a list can be set up containing the voltage adjustment values ​​corresponding to various pressure differences within a pressure difference threshold. The system can determine the matching voltage adjustment value based on this list and then adjust the battery's output voltage. Alternatively, the system can perform real-time calculations. For example, the system can determine whether the battery's output voltage needs adjustment and how it needs to be adjusted based solely on the pressure difference and the pressure difference threshold—that is, whether the battery's output voltage needs to be increased. If adjustment is determined, the current battery output voltage is determined, along with the charging port voltage / adapter connection voltage. Then, based on the two determined voltage values, the pressure difference, and the target threshold, the required increase in the battery's output voltage is determined, and the voltage regulator is controlled to adjust accordingly.

[0065] For example, if the voltage when the adapter connector is disconnected is 20V, while the battery can supply 6V to the charging port, then the voltage difference between the adapter connector voltage and the charging port voltage is 14V. Assuming a voltage difference threshold of 13V-15V, the voltage difference is within this threshold, so the battery output voltage needs to be adjusted. The system can then look up the corresponding battery output voltage adjustment value when the voltage difference is 14V and the port voltage is 20V. For example, if the adjustment value is 6V, the system can control the voltage regulator to adjust the battery output voltage to 12V. This results in a voltage difference of 8V between the battery and the adapter connector voltage, which is less than the target threshold of 12V, thus preventing switching arcing. Alternatively, if the system determines that the voltage when the adapter connector is disconnected is 20V, and the battery can supply 6V to the charging port, then with the adapter disconnected, the voltage difference between the adapter connector and the charging port is 14V, which is within the voltage difference threshold. In this case, if voltage adjustment is needed, the system can calculate based on the voltage when the adapter connector is disconnected, the battery supply voltage to the charging port, and the target threshold. This calculation would determine that the battery output voltage needs to be increased to at least 12V to prevent switching arcing when disconnected. Furthermore, if the port voltage and adapter connector voltage are determined, and the voltage difference is calculated to be less than the voltage difference threshold, then the current battery output voltage is not low and meets the requirements, requiring no adjustment. In this case, the system can remain inactive and only control the first switch.

[0066] In practical applications, the voltage adjustment value can also be a fixed value. For example, the voltage adjustment value can be predetermined based on the battery voltage in the actual device and the charging voltage of the adapter. Then, when the adapter is disconnected from the charging port, the system can directly control the voltage regulator to adjust the battery output voltage based on the predetermined voltage adjustment value.
