Description

Sheath with solar charging unit

technical field

The utility model relates to a sheath, in particular to a sheath with a solar charging device used for similar electrical products such as mobile phones, laptop computers or game machines.

Background technique

As we all know, solar energy is inexhaustible, environmentally friendly and clean, and plays an irreplaceable role in the absence of AC power supply. When solar panels and rechargeable batteries are used together, they can form an independent uninterrupted DC power supply system, which can continuously provide electrical energy for electrical products.

In the prior art, chargers are generally used for charging such as laptop computers and mobile phones, and all of them are charged after being converted into low voltage by commercial power. Sometimes the standby time is longer, which brings inconvenience to going out or outdoor sports and consumes electric energy on the grid, and is sometimes unable to charge because the interface is not matched.

Utility model content The purpose of this utility model is to provide a sheath with a solar charging device, which brings convenience to charging mobile phones, laptops or game consoles and similar electrical products and saves electric energy on the grid.

In order to achieve the above object, the utility model provides the following scheme: design a sheath with a solar charging device, which is compatible with the shape and size of the corresponding electrical product, and the charging device of the sheath is composed of solar panels 5, liters The voltage circuit board 2 and the power adapter socket 1 are composed, the solar cell panel 5 is fixed on the outer side of the sleeve body 6 and the panel faces outward, the output end of the solar cell panel 5 is connected with the input end of the booster circuit board 2, and the booster circuit The output end of the board 2 is connected with the power adapter socket 1 through wires, and the boost circuit board 2 is fixed in the casing 6 .

The sleeve body 6 of the utility model also has a rechargeable battery 3, and the input end and the output end of the rechargeable battery 3 are respectively connected with the output end of the solar panel 5 and the input end of the boost circuit board 2.

When the sunlight is directly irradiated, the solar panel 5 generates a voltage, which charges the built-in rechargeable battery 3 through the diode D1 for later use; The connection port can charge electrical products.

When there is no sunlight, the voltage generated by the solar panel is very low, which cannot provide the normal working voltage for the rechargeable battery. At this time, the built-in rechargeable battery starts to discharge, and it passes through the voltage regulator ZD1 to the output interface, and plugs in the matching Connecting port to charge electrical products.

The utility model can be made of materials such as corium, leather and plastics.

Compared with the prior art, the utility model has the advantages of simple structure, energy saving, portability and wide applicability.
