[0026] Such as Figure 1As shown in the figure, the battery life system of the mobile terminal of the present utility model includes a charging station arranged outside the mobile terminal. A battery compartment is provided in the charging station, and three replacement batteries are provided in the battery compartment. Three first power supply interfaces are provided at positions corresponding to the replacement batteries in the battery compartment. The first power supply interfaces correspond to the three replacement batteries one by one. The three replacement batteries can directly supply power to the mobile terminal through the first power supply interfaces, or can supply power to the mobile terminal by replacing the battery of the mobile terminal with a replacement battery.

[0027] The present utility model provides multiple replacement batteries in the charging compartment to solve the emergency of temporary mobile office, and can greatly reduce the charging time when storing electricity. In addition, in the case of no power, multiple replacement batteries provide a favorable guarantee for power supply, thus greatly reducing the range anxiety.

[0028] In addition, a DC output structure is also provided in the charging station of the present utility model. The DC output structure is provided with several power supply branches, and several second power supply interfaces corresponding to the power supply branches one by one are provided on the charging station. The second power supply interfaces can supply power to the mobile terminal.

[0029] The present utility model provides a charging station outside the mobile terminal, which can convert wall electricity into direct current required by the mobile terminal and charge multiple mobile terminals simultaneously through multiple second power supply interfaces, further enriching the power supply method. Of course, the number of replacement batteries and the number of second power supply interfaces in this example are not limited to 3, and can be set to more according to requirements.

[0030] A power supply circuit for charging the replacement batteries and providing power to the DC output structure is provided in the charging station, and a power input interface connected to an external power supply is also provided. The output end of the power input interface is connected to the power supply circuit.

[0031] As Figure 2 shown, as an embodiment of the present utility model, the input end of the power supply circuit of this example is connected to the AC_IN interface of the power input interface, and takes power from the wall electricity alternating current. The power supply circuit includes a filtering module, a protection module, an anti-reverse connection module and a power conversion module. Among them, the protection module is arranged at the output end of the power input interface, the anti-reverse connection module and the power conversion module are arranged in sequence at the output end of the protection module. The power conversion module is used to convert the alternating current of the wall electricity into the direct current power required by the power supply circuit. The direct current power supplies power to the replacement batteries and the DC power supply structure. The filtering module is arranged at the power input end and the output end of the power supply circuit.

[0032] The filtering module in this example includes Y capacitors C1 and C2 respectively set at the output end of the power input interface, and capacitors C3, C4 - C6 set at the input end and output end of the power conversion module. The protection module in this example includes a fuse F1 and a varistor R4, which provide overcurrent and overvoltage protection for the entire circuit.

[0033] The reverse connection prevention module in this example includes resistors R1, R2 and a switching transistor Q2. Among them, the resistors R1 and R2 are connected in series between the live wire and the neutral wire, the source and drain of the switching transistor Q2 are connected in series on the neutral wire, and the gate is connected between the resistors R1 and R2. The power conversion module in this example includes a transformer AC - DC and a rectifier bridge DD1. The output ends of the rectifier DD1 are respectively connected in parallel to a plurality of battery interfaces BATTERY for powering the replacement battery and a plurality of second power supply interfaces DEVICE for powering the mobile terminal.

[0034] Preferably, the power supply circuit further includes an anti - interference module, which is set at the output end of the reverse connection prevention module, and a transient suppression module set between the reverse connection prevention module and the anti - interference module.

[0035] The anti - interference module in this example is differential - mode inductors L1 and L2 connected in series on the wall - power live wire and neutral wire power supply lines, and the transient suppression module in this example is a TVS tube Z1.

[0036] The working principle of the power supply circuit in this example is as follows:

[0037] After the wall power is input through the AC_IN interface, it passes through the filtered Y capacitors C1 and C2, and then through the protection circuits such as the fuse F1 for overcurrent protection, the varistor R4, the reverse connection prevention module, and the TVS tube Z1. Then, it passes through anti - interference components such as the differential - mode inductors L1 and L2 and filtering capacitors. Then, through the transformer AC - DC and the rectifier bridge DD1, the 220V alternating current is converted into the direct current required by the device and the battery. In this example, the DC voltage can be determined according to the demand for direct current at the back end to select the transformer type. Finally, it is output to the battery interface BATTERY and the second power supply interface DEVICE after passing through the filtering capacitor C6. Among them, the number of charging ports for the battery and the number of power supply ports for the device are set according to the demand, but the power consumption of the load end needs to be evaluated synchronously to confirm the device selection in the charging bin.

[0038] Such as Figure 3As shown in the figure, as an embodiment of the present utility model, a buck-boost IC, a charging IC, and a power path selection module are provided inside the mobile terminal. Among them, the input end of the buck-boost IC is connected to an external power supply of the mobile terminal, and the output end is connected to the charging IC. The charging IC is respectively connected to the main battery and the secondary battery to charge the main battery and the secondary battery. The selection end of the power path selection module is respectively connected to the output ends of the main battery, the secondary battery, and the charging IC, and the normally connected end of the power path selection module supplies power to the load.

[0039] The input source can be either direct current or an external battery. When a direct current or an external battery is connected, since the input voltage is not a fixed value, a stable voltage value is output through the buck-boost chip; then, the device is powered and the main and secondary batteries are charged through the charging IC; the power path selection module is used to select the input source according to the different states of the battery and the external power supply. The power path selection sets priorities among the 2nd, 3rd, and 5th paths, with the priority being 3 > 2 > 5. When a direct current input or an external battery input occurs, the 1st, 3rd, and 4th paths are conducting, the 2nd and 5th paths are non-conducting, the 1st and 4th paths are charging paths, and the 3rd path is the path for supplying power to the load. When there is no external input, the 2nd path is conducting, and the 1st, 3rd, 4th, and 5th paths are non-conducting. When there is neither an external input nor a main battery, the 5th path is conducting, and the 1st, 2nd, 3rd, and 4th paths are non-conducting. Through the power path selection, the power supply usage of the battery can be reasonably arranged, ensuring the product's battery life for the user in any usage environment to the greatest extent.

[0040] In this example, both the buck-boost IC and the charging IC can use the circuits inside the mobile terminal, or can be selected according to actual usage requirements. The power path selection module can be an electronic switching switch, and intelligent switching can be achieved by setting the priorities of each branch. Whether to configure a secondary battery inside the mobile terminal can be determined according to actual needs.

[0041] From the above description, it can be seen that the present utility model adopts multiple power supply methods to adapt to various usage environments of users and improve the battery life, with the following prominent advantages:

[0042] 1. Improve the battery life by swapping the internal and external batteries;

[0043] 2. The charging bin can charge multiple devices or batteries simultaneously, greatly shortening the charging time and at the same time solving the battery life anxiety;

[0044] 3. Both the DEVICE and the BATTERY can be powered through the power supply interface. Multiple power supply methods can adapt to various usage environments of users and improve the battery life;

[0045] 4. The existence of the built-in secondary battery can not only improve the battery life to a certain extent, but also directly replace the main battery when the device is in working state, thus improving the efficiency.

[0046] The specific embodiments described above are the preferred embodiments of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to these specific embodiments. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
