Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the solar energy box of the present embodiment comprises a solar panel 1, a power module 2 installed on the inside of the solar panel 1, an outer cover 3 installed on the outside of the power module 2, a handle 4 installed on the outer cover 3 and a The corner protector 5 at the right angle of the solar panel 1 to prevent the solar panel 1 from being damaged.

The solar panel 1 in the present embodiment is a rectangular flat plate, which is made of high-quality monocrystalline silicon. Its principle is the photoelectric effect, that is, when the ray is irradiated on different conductors or semiconductors, the photons interact with the free electrons in the conductors or semiconductors to generate current, and the light A method of generating electricity that can be converted into electrical energy.

As shown in FIG. 2 to FIG. 3 , the power module 2 includes a plurality of closely arranged batteries 21 , and the batteries 21 are lithium batteries with large capacity, and may also be rechargeable batteries in other forms. A switch 22 for controlling the charging of the solar panel 1 is installed on one side of the battery 21, and a charging interface 23 is installed on the other side of the battery 21, including two DC interfaces and a USB interface, which can be used for digital products, communication products, and household appliances outdoors. and other devices to connect to use.

The power module 2 also includes a lower circuit board 24, the edge of the circuit board 24 is fixed on the solar panel 1 by arranging a plurality of screws, and the circuit board 24 selects a PCB circuit board for electrical connection between components. The battery 21, the switch 22 and the charging interface 23 are all electrically connected to the circuit board 24, and the wiring side of the circuit board 24 is also provided with a hollow cylindrical waterproof ring 25.
