Please refer to FIG. 1, which is a block diagram of an embodiment of the combined power supply device of the present invention. As shown in the figure, the present invention provides a power supply device 1, which allows users to decide whether to perform solar charging, and to perform conversion and plug-in. The solar panel 3 or a lighting device 4, the power supply device 1 includes: a secondary battery 10, a charging circuit 20, a first connection unit 30, a control unit 40, at least one power output unit 50, an operating unit 60 and a display unit 70 . When the power supply device 1 is in a sunny environment and the user wants to charge the solar energy, the solar panel 3 is plugged into the first connection unit 30 , and the first connection unit 30 can then transmit the energy converted by the solar panel 3 The output electric energy is further provided to the charging circuit 20 electrically connected between the first connection unit 30 and the secondary battery 10 to charge the secondary battery 10, and when the secondary battery 10 is in the state of storing electric energy , so as to generate a first voltage 101 and a second voltage 102 .

Wherein, the secondary battery 10 can be, for example, a lead-acid battery, and the solar panel 3 can, for example, further include a voltage regulation circuit 301 to boost and stabilize the electric energy converted by the solar panel 3 to form a fixed voltage. Furthermore, the fixed voltage is provided to the charging circuit 20 through the first connection unit 30 to charge the secondary battery 10 , and in the present invention, the fixed voltage is, for example, designed to be a fixed voltage of 5 volts.

The control unit 40 is electrically connected to the secondary battery 10 for controlling the second voltage 102 to convert and output at least one output voltage 103 , and then provide it to an application device 2 through the power output unit 50 . Wherein the power output unit 50 can be, for example, a USB connection port or a power connection port, which is electrically connected to the control unit 40 to provide the user with a suitable application device 2, so that the application device 2 can obtain the power supply device 1. provides an output voltage of 103 . In addition, the operation unit 60 in the power supply device 1 is electrically connected to the control unit 40 to provide an operation interface for the user to adjust the operation according to the operating voltage of the application device 2 to be connected, that is, the operation unit 60 can adjust the output of the second voltage 102 controlled by the control unit 40 , and then change the magnitude of the output voltage 103 to meet the needs of the external application device 2 . However, in the present invention, the above-mentioned operation interface can be realized by buttons or knobs, for example.

The display unit 70 is also electrically connected to the control unit 40, and at the same time judges the current voltage level of the secondary battery 10 according to the voltage detection circuit (not shown) used by the control unit 40 to control and detect the secondary battery 10, and then The display unit 70 can display the power status or charging status of the secondary battery 10. Furthermore, the display unit 70 can further display the output voltage 103 currently controlled by the control unit 40, so that users can clearly know their own For the adjusted output voltage, the display unit 70 can, for example, adopt a general small display (such as a liquid crystal display (Liquid Crystal Display, LCD)) in practical applications. In addition, it can also be designed by combining different light emitting diodes (LEDs) To achieve the change on the display, it can also achieve the effect of providing the user with information about the current secondary battery 10 .

The above description is based on the assumption that the first connection unit 30 is plugged into the solar panel 3. In the above situation, the user places the power supply device 1 in an environment where the sun shines in the morning and can perform solar charging. When irradiating, since the secondary battery 10 is fully charged, the user can remove the solar panel 3 from the first connection unit 30, and then replace the lighting device 4 with the same first connection unit 30, At this time, the first voltage 101 generated by the secondary battery 10 is directly provided to the lighting device 4 to generate a light source.

However, the power supply device 1 can not only generate lighting effects through the lighting device 4 plugged into the first connection unit 30, but also the power output unit 50 can still provide the application device 2 required by the user for connection at the same time, and also The magnitude of the output voltage 103 can be adjusted through the operating unit 60 , and relevant information of the secondary battery 10 can be displayed through the display unit 70 . Thus, in addition to the light source generated by the lighting device 4 itself, the power supply device 1 can also provide different output voltages 103 according to the voltage required by the user, so the power supply device 1 can have a light source and a power supply at the same time. Effect.

In addition, in order to prevent the power supply device 1 from incompletely charging the secondary battery 10 in an environment with insufficient sunlight, or the situation that the secondary battery 10 is depleted at night, the present invention further designs a power input unit 80, It is electrically connected to the charging circuit 20 for receiving a commercial power 104 and directly charging the secondary battery 10, so that the power supply device 1 can not only continue to perform the power storage function of the secondary battery 10, but also provide light source and power supply.

Incidentally, the present invention further designs a second connection unit 90, which corresponds to the design of the first connection unit 30, so that when the user has multiple power supply devices 1, the second connection of the original power supply device 1 can be used. The unit 90 is connected to the first connecting unit 30 of another power supply device 1 to connect with each other, so as to achieve the function of connecting multiple secondary batteries 10 in series or in parallel, allowing users to have more combinations of the power supply device 1 .

Please refer to FIG. 2 , the flow chart of an embodiment of the operation method of the combined power supply device of the present invention, as shown in the figure, the present invention provides a kind of operation method of the power supply device 1 , the steps include: first, determine whether the power supply device 1 is connected to the market Electricity 104 (S201), if the determination result is no, it is further determined whether the first connection unit 30 is plugged with the solar panel 3 (S203). Wherein, if the judgment result of step (S201) is yes, that is, the power supply device 1 is connected to the mains 104 through the power input unit 80, or the judgment result of step (S203) is yes, that is, the solar energy is plugged in through the first connection unit 30 In the case of the plate 3, the secondary battery 10 is charged to generate the first voltage 101 and the second voltage 102 (S205).

After step (S205) or under the situation that the judgment result of step (S203) is negative, it is judged whether the first connection unit 30 is plugged with the lighting device 4 (S207), and it is also judged whether the power output unit 50 is connected with In the application device 2 (S209), if the judgment result of the step (S207) is yes, it means that the user has changed and plugged the first connection unit 30 into the lighting device 4. At this time, the first voltage 101 of the secondary battery 10 is Transmission to the lighting device 4, so that the first voltage 101 forms a light source supply (S211); on the other hand, if the judgment result of step (S209) is yes, it means that the user is also connected to the application device 2 for use, so the second The battery 10 generates power supply to provide the second voltage 102 to the application device 2 ( S213 ). In addition, the power supply device 1 is designed with a control unit 40 and an operation unit 60 so that the user can further control the second voltage 102 to output a consistent output voltage 103 according to the working voltage of the application device 2 used.

On the contrary, when judging in step (S207), if the user still connects the solar panel 3 through the first connection unit 30 for solar charging, then the judging result of step (S207) presents the situation of No, so just continue to execute step The processes of ( S207 ) and ( S209 ) continue to determine the connection status of the first connection unit 30 and the power output unit 50 . In terms of step (S209), it is also independently judged to determine whether to provide power to the application device 2, and will not be affected by the judgment result of step (S207). When the panel 3 is being charged by solar energy, the power output unit 50 can also be connected to the application device 2 and receive the power supply from the secondary battery 10 to operate.

As shown in the figure, the first connection unit 30 of the power supply device 1 is plugged into the lighting device 4, so the power supply device 1 does not receive solar energy. Instead, it provides voltage to the lighting device 4 to generate a light source supply to achieve lighting effects. Similarly, the user can also connect the application device 2 (such as an electric iron) through the power output unit 50 at the same time to receive the power supply device 1. The power output unit 50 in this embodiment is exemplified by a power connection port. In addition, the operation unit 60 and the display unit 70 also provide adjustment and display information according to the description of the above embodiment.

When the secondary battery 10 in the power supply device 1 is exhausted, the power input unit 80 can receive the supply of commercial power 104 to charge the secondary battery 10, and at the same time, the power supply device 1 can continue to generate light and Power supply function.

Please refer to FIG. 5 again, which is a schematic diagram of the third application embodiment of the combined power supply device of the present invention.
