[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0023] Terms such as "first" and "second" in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0024] A power supply structure disclosed in an embodiment of the present application includes a first battery assembly, a second battery assembly, and a main board. Among them: a detection and determination circuit is provided on the main board, and the detection and determination circuit is used to cut off the electrical connection between the other of the first battery assembly and the second battery assembly and the power supply port when it is detected that one of the first battery assembly and the second battery assembly is first installed on the main board, and keep the electrical connection between the battery assembly first installed on the main board and the power supply port conducting when it is detected that the other of the first battery assembly and the second battery assembly is also installed on the main board.

[0025] For example, when the detection and determination circuit detects that the first battery assembly is first installed on the main board, the electrical connection between the first battery assembly and the power supply port is conducted, and the electrical connection between the second battery assembly and the power supply port is cut off. When it is detected that the second battery assembly is also installed on the main board, the electrical connection between the first battery assembly and the power supply port is maintained. That is to say, when the second battery assembly is also snapped onto the main board, the first battery assembly still provides voltage to the power supply port, and the second battery assembly temporarily does not provide voltage to the power supply port.

[0026] A power supply structure provided by an embodiment of the present application includes a first battery component, a second battery component, and a main board. A detection and determination circuit is provided on the main board. When the detection and determination circuit on the main board detects that one of the first battery component and the second battery component is first installed on the main board, the detection and determination circuit cuts off the electrical connection between the other battery component and the power supply port, and when the other battery component is also installed on the main board, maintains the electrical connection between the battery component first installed on the main board and the power supply port in a conductive state, thereby solving the problem that there is a situation where a high-voltage battery component charges a low-voltage battery component after different-voltage battery components are installed in parallel.

[0027] In a further technical solution, the detection and determination circuit is further configured to, after detecting that the other of the first battery component and the second battery component is also installed on the main board, obtain the voltage difference between the first battery component and the second battery component. When the voltage difference is less than a threshold value, conduct the electrical connection between the first battery component and the power supply port, and conduct the electrical connection between the second battery component and the power supply port. That is to say, when both the first battery component and the second battery component are installed on the main board, the detection and determination circuit obtains the voltage difference between the first battery component and the second battery component. When the voltage difference between the first battery component and the second battery component is less than the threshold value, while maintaining the electrical connection between the battery component first installed on the main board and the power supply port in a conductive state, conduct the electrical connection between the battery component later installed on the main board and the power supply port, so as to realize the parallel connection of the first battery component and the second battery component to supply power to the power supply port. The threshold value can be set to 3 mV.

[0028] In the present application, the first battery component includes a first power supply pin and a first buckling determination pin; the second battery component includes a second power supply pin and a second buckling determination pin; the detection and determination circuit includes a third power supply pin, a fourth power supply pin, a third buckling determination pin, and a fourth buckling determination pin. The third power supply pin and the fourth power supply pin are respectively electrically connected to the power supply port; when the first battery component is installed on the main board, the first power supply pin is electrically connected to the third power supply pin, and the first buckling determination pin is electrically connected to the third buckling determination pin; when the second battery component is installed on the main board, the second power supply pin is electrically connected to the fourth power supply pin, and the second buckling determination pin is electrically connected to the fourth buckling determination pin.

[0029] In this application, the third power supply pin and the fourth power supply pin are respectively electrically connected to the power supply port. When the first battery assembly is installed on the main board, the first power supply pin is electrically connected to the third power supply pin, and the first fastening determination pin is electrically connected to the third fastening determination pin. When the detection and determination circuit detects through the third fastening determination pin and the fourth fastening determination pin that the first battery assembly is installed on the main board first, the first battery assembly provides voltage to the power supply port, and at the same time, the electrical connection between the fourth power supply pin and the power supply port is cut off. When the detection and determination circuit later detects that the second battery assembly is also installed on the main board, the electrical connection between the third power supply pin and the power supply port remains conductive. That is to say, when the second battery assembly is also installed on the main board, the first battery assembly still provides voltage to the power supply port, and the second battery assembly temporarily does not provide voltage to the power supply port.

[0030] Similarly, when the second battery assembly is installed on the main board, the second power supply pin is electrically connected to the fourth power supply pin, and the second fastening determination pin is electrically connected to the fourth fastening determination pin. When the detection and determination circuit detects through the third fastening determination pin and the fourth fastening determination pin that the second battery assembly is installed on the main board first, the second battery assembly provides voltage to the power supply port, and at the same time, the electrical connection between the third power supply pin and the power supply port is cut off. When the detection and determination circuit later detects that the first battery assembly is also installed on the main board, the electrical connection between the fourth power supply pin and the power supply port remains conductive. That is to say, when the first battery assembly is also installed on the main board, the second battery assembly still provides voltage to the power supply port, and the first battery assembly temporarily does not provide voltage to the power supply port.

[0031] Figure 1 It is a partial structural schematic diagram of a detection and determination circuit disclosed in an embodiment of this application. In the embodiment of this application, as Figure 1 shown, the detection and determination circuit further includes: a first on-off unit and a second on-off unit. Among them, the first end of the first on-off unit is electrically connected to the third power supply pin, the second end of the first on-off unit is electrically connected to the power supply port, and the control end of the first on-off unit is electrically connected to the third fastening determination pin and the fourth fastening determination pin respectively; the first end of the second on-off unit is electrically connected to the fourth power supply pin, the second end of the second on-off unit is electrically connected to the power supply port, and the control end of the second on-off unit is electrically connected to the third fastening determination pin and the fourth fastening determination pin.

[0032] When the fourth latching determination pin is at a high level and the third latching determination pin is at a low level, the electrical connection between the first end and the second end of the first on-off unit is disconnected. And when the third latching determination pin becomes at a high level afterwards, the electrical connection between the first end and the second end of the second on-off unit remains conducting. That is to say, when the second battery assembly is first installed on the main board, the electrical connection between the first end and the second end of the first on-off unit is disconnected, and after the first battery assembly is also installed on the main board, the electrical connection between the first end and the second end of the second on-off unit remains conducting, while the electrical connection between the first end and the second end of the first on-off unit remains temporarily disconnected.

[0033] When the third latching determination pin is at a high level and the fourth latching determination pin is at a low level, the electrical connection between the first end and the second end of the second on-off unit is disconnected. And when the fourth latching determination pin becomes at a high level afterwards, the electrical connection between the first end and the second end of the first on-off unit remains conducting. That is to say, when the first battery assembly is first installed on the main board, the electrical connection between the first end and the second end of the second on-off unit is disconnected, and after the second battery assembly is also installed on the main board, the electrical connection between the first end and the second end of the first on-off unit remains conducting, while the electrical connection between the first end and the second end of the second on-off unit remains temporarily disconnected.

[0034] Taking the first battery assembly being first installed on the main board as an example, in an alternative solution, the first on-off unit and the second on-off unit at this time can be PMOS transistors. When the third latching determination pin is at a high level and the fourth latching determination pin is at a low level, the electrical connection between the first end and the second end of the second on-off unit is disconnected, and the electrical connection between the first end and the second end of the first on-off unit is conducting.

[0035] In another alternative solution, the first on-off unit and the second on-off unit at this time can include a NOT gate and an NMOS transistor. When the third latching determination pin is at a high level and the fourth latching determination pin is at a low level, the high level output by the third latching determination pin is converted to a low level through the NOT gate of the second on-off unit, and the low level is input to the control terminal of the NMOS transistor of the second on-off unit to disconnect the electrical connection between the first end and the second end of the NMOS transistor of the second on-off unit. The low level output by the fourth latching determination pin is converted to a high level through the NOT gate of the first on-off unit, and the high level is input to the control terminal of the NMOS transistor of the first on-off unit to conduct the electrical connection between the first end and the second end of the NMOS transistor of the first on-off unit.

[0036] Certainly, the embodiments of the present application do not limit the specific configurations of the first on-off unit and the second on-off unit, as long as the electrical connection between the corresponding first end and the second end can be conducted when the control terminals of the first on-off unit and the second on-off unit are input with a high level.

[0037] In a further technical solution, the detection and determination circuit further includes: a third on-off unit, a fourth on-off unit, a first resistor unit, and a second resistor unit. Among them, the control end of the third on-off unit is electrically connected to the fourth fastening determination pin, the first end of the third on-off unit is electrically connected to the control end of the first on-off unit, the second end of the third on-off unit is grounded, and when a high level is input to the control end of the third on-off unit, it controls the electrical connection between the first end and the second end of the third on-off unit to conduct; the control end of the fourth on-off unit is electrically connected to the third fastening determination pin, the first end of the fourth on-off unit is electrically connected to the control end of the second on-off unit, the second end of the fourth on-off unit is grounded, and when a high level is input to the control end of the fourth on-off unit, it controls the electrical connection between the first end and the second end of the fourth on-off unit to conduct; one end of the first resistor unit is electrically connected to the fourth fastening determination pin, and the other end is electrically connected to the first end of the fourth on-off unit; one end of the second resistor unit is electrically connected to the third fastening determination pin, and the other end is electrically connected to the first end of the third on-off unit; when a low level is input to the control end of the first on-off unit, it controls the electrical connection between the first end and the second end of the first on-off unit to be disconnected; when a low level is input to the control end of the second on-off unit, it controls the electrical connection between the first end and the second end of the second on-off unit to be disconnected.

[0038] The first resistor unit and the second resistor unit can ensure that when another battery assembly is fastened to the main board, the electrical connection between the first end and the second end of the on-off unit electrically connected to the previously fastened battery assembly remains conductive.

[0039] Figure 2 This is a partial structural schematic diagram of another detection and determination circuit disclosed in the embodiments of the present application. In the embodiments of the present application, as Figure 2 shown, the first on-off unit and the second on-off unit can be NMOS transistors. The control ends of the first on-off unit and the second on-off unit are the gates of the NMOS transistors.

The second ends of the first on-off unit and the second on-off unit are the drains of the NMOS transistors. The third on-off unit and the fourth on-off unit can be NPN transistors. The control ends of the third on-off unit and the fourth on-off unit are the bases of the NPN transistors. The first ends of the third on-off unit and the fourth on-off unit are the collectors of the NPN transistors. The second ends of the third on-off unit and the fourth on-off unit are the emitters of the NPN transistors.

[0040] As Figure 2As shown, during the assembly of the power supply structure, when the first battery VBAT1 is first installed on the main board and the second battery VBAT2 is installed on the main board later, when VBAT1 is installed on the main board, the first latching determination pin is electrically connected to the third latching determination pin EN_det1 in the detection determination circuit, making EN_det1 at a high level. The first end and the second end of the fourth switching unit Q4 are turned on, G2 is pulled low, and then the first end and the second end of the second switching unit Q2 are turned off. At this time, the fourth latching determination pin EN_det2 is at a low level, the first end and the second end of the third switching unit Q3 are turned off, G1 is pulled high, the first end and the second end of the first switching unit Q1 are turned on, and the power supply path of VBAT1 is turned on. The voltage of the power supply port VPH is equal to the voltage of VBAT1. At this time, VBAT2 is installed on the main board again. Since the second switching unit Q2 is turned off, VBAT2 will not directly supply power to VPH.

[0041] During the assembly of the power supply structure, when the second battery VBAT2 is first installed on the main board and the first battery VBAT1 is installed on the main board later, when VBAT2 is installed on the main board, the second latching determination pin is electrically connected to the fourth latching determination pin EN_det2 in the detection determination circuit, making EN_det2 at a high level. The first end and the second end of the third switching unit Q3 are turned on, G1 is pulled low, and then the first end and the second end of the first switching unit Q1 are turned off. At this time, the third latching determination pin EN_det1 is at a low level, the first end and the second end of the fourth switching unit Q4 are turned off, G2 is pulled high, the first end and the second end of the second switching unit Q2 are turned on, and the power supply path of VBAT2 is turned on. The voltage of the power supply port VPH is equal to the voltage of VBAT2. At this time, VBAT1 is installed on the main board again. Since the first switching unit Q1 is turned off, VBAT1 will not directly supply power to VPH.

[0043] In the embodiment of the present application, as Figure 4 shown, the fifth switching unit and the sixth switching unit can be NPN transistors, the control ends of the fifth switching unit and the sixth switching unit are the bases of the NPN transistors, the first ends of the fifth switching unit and the sixth switching unit are the collectors of the NPN transistors, and the second ends of the fifth switching unit and the sixth switching unit are the emitters of the NPN transistors.

[0044] As Figure 4As shown, the first voltage detection pin VBAT1-sense of the power management integrated circuit module (AP+PMIC) is electrically connected to the third power supply pin VBAT1, the second voltage detection pin VBAT2-sense of the power management integrated circuit module (AP+PMIC) is electrically connected to the fourth power supply pin VBAT2, and the enable pin ALL-bat_on of the power management integrated circuit module (AP+PMIC) is electrically connected to the control ends of the fifth switching unit Q5 and the sixth switching unit Q6 respectively.

[0047] Based on the power supply structure disclosed in the embodiments of the present application, an electronic device is disclosed in the embodiments of the present application, including the power supply structure in the above embodiments. There are many types of electronic devices, such as mobile phones, tablets, etc. The embodiments of the present application do not make specific limitations thereto.

[0048] Figure 6 It is a schematic flowchart of a power supply method for a power supply structure disclosed in the embodiments of the present application, which is applied to an electronic device. This method can be executed by the electronic device, such as a terminal device and / or a server. In other words, this method can be executed by software or hardware installed in the terminal device and / or the server. As Figure 6 shown, this method may include the following steps:

[0049] S601. When it is detected that the first battery component is installed on the main board and the second battery component is not installed on the main board, cut off the electrical connection between the second battery component and the power supply port.

[0050] Specifically, when it is detected that the first battery component is installed on the main board and the second battery component is not installed on the main board, the first power supply pin is electrically connected to the third power supply pin, the first fastening determination pin is electrically connected to the third fastening determination pin, the third fastening determination pin is at a high level, and the fourth fastening determination pin is at a low level. Furthermore, the electrical connection between the first end and the second end of the first on-off unit is conducted, and the electrical connection between the first end and the second end of the second on-off unit is disconnected. At this time, the power supply path of the first battery component is turned on, the power supply path of the second battery component is turned off, and the first battery component provides voltage to the power supply port.

[0051] S602. After it is detected that the second battery component is installed on the main board, keep the electrical connection between the second battery component and the power supply port disconnected.

[0052] In the case where the first battery component is installed on the main board first and the second battery component is installed on the main board later, when it is detected that the second battery component is installed on the main board, due to the action of the first resistance unit and the second resistance unit, the electrical connection between the first end and the second end of the first on-off unit remains conducted. That is to say, when the second battery component is also installed on the main board, the power supply path of the first battery component remains turned on, the power supply path of the second battery component remains temporarily turned off, and the first battery component still provides voltage to the power supply port, and the second battery component does not provide voltage to the power supply port temporarily.

[0053] A power supply method for a power supply structure provided by an embodiment of the present application. When it is detected that the first battery component is installed on the main board and the second battery component is not installed on the main board, the electrical connection between the second battery component and the power supply port is cut off. When it is detected that the second battery component is installed on the main board, the electrical connection between the second battery component and the power supply port remains disconnected, effectively solving the problem that there is a high-voltage battery charging a low-voltage battery after battery components with different voltages are installed in parallel.

[0054] In an embodiment of the present application, after it is detected that the second battery component is installed on the main board, the method further includes: obtaining a first power supply voltage of the first battery component and a second power supply voltage of the second battery component; when the voltage difference between the first power supply voltage and the second power supply voltage is less than a threshold, keeping the electrical connection between the first battery component and the power supply port conducting, and conducting the electrical connection between the second battery component and the power supply port. That is to say, when the first battery component is first installed on the main board and the second battery component is also installed on the main board, the power management integrated circuit module detects the first power supply voltage of the first battery component and the second power supply voltage of the second battery component, and calculates the voltage difference between the first power supply voltage and the second power supply voltage. When the voltage difference between the first power supply voltage and the second power supply voltage is less than the threshold, the enable pin of the power management integrated circuit module outputs a high level to the control ends of the fifth switching unit and the sixth switching unit, so that while keeping the electrical connection between the first end and the second end of the first switching unit conducting, the electrical connection between the first end and the second end of the second switching unit also conducts, realizing that the first battery component and the second battery component are connected in parallel to supply power to the power supply port. The threshold can be set to 3 mV.

[0055] In a possible implementation manner, after detecting the first power supply voltage of the first battery component and the second power supply voltage of the second battery component, the method further includes: when the first power supply voltage is greater than the second power supply voltage and the voltage difference between the first power supply voltage and the second power supply voltage is not less than the threshold, keeping the electrical connection between the second battery component and the power supply port disconnected. In this case, keep the electrical connection between the first end and the second end of the first switching unit conducting, and the electrical connection between the first end and the second end of the second switching unit disconnected. The first battery component provides voltage to the power supply port, consuming the first power supply voltage of the first battery component. While the first battery component is working, the power management integrated circuit module continues to detect the first power supply voltage of the first battery component and the second power supply voltage of the second battery component. When the voltage difference between the first power supply voltage and the second power supply voltage is less than the threshold, the enable pin of the power management integrated circuit module outputs a high level to the control ends of the fifth switching unit and the sixth switching unit, so that while keeping the electrical connection between the first end and the second end of the first switching unit conducting, the electrical connection between the first end and the second end of the second switching unit also conducts, realizing that the first battery component and the second battery component are connected in parallel to supply power to the power supply port.

[0056] Similarly, if the second battery module is first installed on the main board and the first battery module is later installed on the main board, its working condition is similar to that when the first battery module is first installed on the main board and the second battery module is later installed on the main board, which will not be elaborated here.

[0057] In another possible implementation manner, after detecting the first power supply voltage of the first battery module and the second power supply voltage of the second battery module, the method further includes: when the first power supply voltage is less than the second power supply voltage and the voltage difference between the first power supply voltage and the second power supply voltage is not less than a threshold value, prompting to charge the first battery module. In this case, by charging the first battery module, the first power supply voltage of the first battery module is increased.

[0058] Similarly, if the second battery module is first installed on the main board and the first battery module is later installed on the main board, its working condition is similar to that when the first battery module is first installed on the main board and the second battery module is later installed on the main board, which will not be elaborated here.

[0059] Further, after prompting to charge the first battery module, the method further includes: detecting the first power supply voltage of the first battery module; when the voltage difference between the first power supply voltage and the second power supply voltage is less than the threshold value, keeping the electrical connection between the first battery module and the power supply port conducting and conducting the electrical connection between the second battery module and the power supply port. Specifically, during the charging process of the first battery module, the power management integrated circuit module continues to detect the first power supply voltage of the first battery module and the second power supply voltage of the second battery module. When the voltage difference between the first power supply voltage and the second power supply voltage is less than the threshold value, the enable pin of the power management integrated circuit module outputs a high level to the control ends of the fifth switching unit and the sixth switching unit, so that the first switching unit and the second switching unit are simultaneously conducted, and the first battery module and the second battery module are connected in parallel to supply power to the power supply port.
