[0020] Figure 1 FIG. is a schematic structural diagram of a power supply circuit for a mobile power base provided by an embodiment of the present invention. This embodiment is applicable to the case where a mobile power supplies an AC device. As Figure 1 shown, the circuit includes: a mobile power supply 110 and a base 120. The mobile power supply 110 is connected to the base 120 through an interface module 140. The base 120 includes a first control module 130 and a power supply output module 150. The first control module 130 is connected to the interface module 140, and the interface module 140 is connected to a load 160 through the base 120. The mobile power supply 110 is used to output a first voltage. The first voltage is used to drive the first control module 130 of the base 120 to power on. The first control module 130 is used to control the mobile power supply 110 to output electric energy according to the connection state between the mobile power supply 110 and the base 120. The first control module 130 is connected to the power supply output module 150, and the power supply output module 150 is used to connect to the load 160. The first control module 130 is used to control the power supply output module 150 to output electric energy to the load 160 when the mobile power supply 110 is removed, has insufficient power, fails, or is replaced.

[0021] Specifically, the mobile power supply 110 refers to a portable battery device that specifically provides electrical energy for various electronic devices. Usually, a lithium-ion battery is installed inside it, enabling the storage and release of electrical energy. The base 120 refers to an expansion device of the mobile power supply 110, which can connect the mobile power supply 110 and other electronic devices. The load 160 refers to a device connected to the base 120. Exemplarily, the load 160 is an electronic device that requires alternating current or direct current.

[0022] The first control module 130 refers to a component in the base 120 that is responsible for managing and controlling the electrical energy output of the mobile power supply 110. After the mobile power supply 110 is connected to the base 120, the mobile power supply 110 can power on the first control module 130 in the base 120. After the first control module 130 is powered on, it can control the mobile power supply to output electrical energy to external devices through each output interface of the base 120. The first voltage refers to the voltage output by the mobile power supply 110, which can power on the first control module 130. Exemplarily, the first voltage can be 3.3V. Exemplarily, the first control module 130 controls the mobile power supply 110 or the base power supply output module to supply power to external devices according to the connection state between the mobile power supply 110 and the base 120. Among them, when the mobile power supply 110 is placed on the base 120, the base 120 transmits the electrical energy of the mobile power supply 110 to each output interface of each interface output module 170 to supply power to the load 160. When the mobile power supply 110 is taken away from the base 120, the output of the mobile power supply 110 stops, and the power supply output module 150 on the base 120 starts to continue to supply power to the load 160.

[0023] The interface module 140 refers to the interface between the mobile power supply 110 and the base 120. The mobile power supply 110 exchanges data or transmits electrical energy with the base 120 through the interface module 140. Exemplarily, the interface module 140 can be designed in the way of pin contacts (pogopin). The way of pogopin allows the mobile power supply 110 to make a reliable electrical connection with the base 120 through elastic pin contacts to ensure stable electrical energy transmission and signal interaction. In the embodiment of the present invention, the mobile power supply 110 is connected to the base 120 through the interface module 140, which can prevent the interface of the mobile power supply 110 from being worn due to frequent plugging and unplugging of the load 160 that needs to be charged, improving the service life of the mobile power supply 110 and the charging stability of the electrical equipment.

[0024] The power supply output module 150 refers to a module on the base 120 that can provide electrical energy for the load 160. In the embodiment of the present invention, the power supply output module 150 includes a battery pack, which can supply power to the load 160 for a short time when the mobile power supply 110 is removed, the power is insufficient, there is a fault, or a switch occurs, thereby ensuring that the load 160 will not lose power.

[0025] In an embodiment of the present invention, the mobile power supply 110 supplies power to the load 160 through the base 120. After the mobile power supply 110 is connected to the base 120, the mobile power supply 110 outputs a first voltage, and the first voltage can power on the first control module 130 in the base 120. After the first control module 130 is powered on, it can automatically determine the connection state between the base 120 and the mobile power supply 110. If the connection state is normal, the first control module 130 controls the mobile power supply 110 to output electrical energy to the base 120. When the mobile power supply 110 supplies power to the base 120, the power supply output module 150 on the base 120 is in a standby state and does not participate in power supply. When the mobile power supply 110 is removed, has insufficient power, fails, or is replaced, the connection between the mobile power supply 110 and the base 120 is disconnected. After the first control module 130 on the base 120 detects this change, it automatically switches to the power supply output module 150 for power supply. That is, the power supply output module 150 is automatically started to continue supplying power to the load 160 through the base 120, avoiding power-off of the load 160 due to the removal of the mobile power supply 110. Among them, the capacity of the power supply output module 150 is designed to enable the load 160 to continue working within a first preset time after the mobile power supply 110 is removed. Within the first preset time, data can be saved or other measures can be taken to avoid adverse effects caused by power-off of the device.

[0026] For the technical solution of the embodiment of the present invention, on the one hand, the mobile power supply supplies power to the load through the base, avoiding interface wear caused by frequent switching between the electrical device and the mobile power supply, and improving the charging stability of the electrical device. On the other hand, the first control module can identify the connection state between the mobile power supply and the base. When the mobile power supply is removed, has insufficient power, fails, or is replaced, it automatically controls the power supply output module to supply power to the load, avoiding damage to the electrical device due to instantaneous power-off. That is, the present invention can ensure continuous power supply to the electrical device, improving the reliability and stability of the mobile power supply for power supply, thereby solving the problem of poor reliability in the process of the mobile power supply supplying power to the electrical device.

[0038] In the embodiment of the present invention, under the control of the second control module 113, the power management module 111 can cause the battery pack 116 to release the stored electrical energy to output the first voltage to supply power to the base 120.

[0039] Figure 4 This is a schematic structural diagram of a mobile power supply provided by an embodiment of the present invention. On the basis of the above embodiments, as Figure 4 shown, the mobile power supply 110 further includes: a switch module 112, the switch module 112 is connected between the power management module 111 and the interface module 140, and the control end of the switch module 112 is connected to the enable end of the second control module 113; when the mobile power supply 110 is connected to the base 120 through the interface module 140, the second control module 113 is used to generate a first enable signal according to the connection state between the mobile power supply 110 and the base 120; the switch module 112 is used to conduct according to the first enable signal, and the second control module 113 is used to communicate with the base 120 and control the base 120 to output electrical energy; when the mobile power supply 110 is disconnected from the base 120, the second control module 113 is used to generate a second enable signal according to the disconnection state between the mobile power supply 110 and the base 120; the switch module 112 is used to turn off according to the second enable signal.

The power management module 123 can intelligently distribute the electrical energy of the base 120 according to the load demand and the power supply status to ensure the normal operation of each module.

[0050] In an embodiment of the present invention, the first control module 130 can automatically identify the connection relationship between the mobile power supply 110 and the base 120. After the mobile power supply 110 is reliably connected to the base 120, the first control module 130 controls the power management module 123 to distribute the electric energy input to the base 120. Exemplarily, a part is used to supply power to the load 160, a part is used to maintain the operation of each module in the base 120, and another part is used to charge the battery pack in the power supply output module 150. When the mobile power supply 110 is removed, has insufficient power, fails, or is replaced, the power management module 123 can distribute the electric energy output by the power supply output module 150. Exemplarily, a part is used to provide electric energy to the load 160, and another part is used to maintain the normal operation of each module of the base 120 itself.

[0052] Specifically, the first electrostatic protection module 121 refers to a component in the base 120 for suppressing the static voltage. The one-way conduction module 122 refers to a module composed of a switching tube or a diode, which can restrict the current flow direction to be only from the first electrostatic protection module 121 to the first control module 130, thereby preventing the current from flowing backward.

[0053] In an embodiment of the present invention, the electric energy output by the mobile power supply 110 is input to the base 120 via the interface module 140.
