Description

Portable device charging suitcase with solar cell deck

technical field

The utility model relates to the field of bags, in particular to a suitcase.

Background technique

The most troublesome thing for business trips and leisure trips is that portable devices such as PCs, mobile phones, and digital cameras are out of power, and it is inconvenient to find a place to charge them, which affects the normal use of portable devices.

The suitcase is a must-have item for carrying clothes and other documents when going out for business or leisure travel. The existing suitcase only has a single storage function and does not have an extended charging function.

Utility model content

The purpose of the utility model is to provide a charging suitcase for portable equipment provided with a solar cell layer, so as to solve the above technical problems.

The technical problem solved by the utility model can be realized by adopting the following technical solutions:

A charging suitcase for portable equipment provided with a solar cell layer, comprising a box, characterized in that a solar panel is fixedly connected to the outside of the box, the solar panel is connected to a solar controller, and the solar controller A storage battery is connected, and the storage battery is connected to a power output terminal.

There is a solar panel outside the box, which converts the sun's radiant light energy into electrical energy and sends it to the battery for storage. The solar controller controls the charging and discharging of the battery. When the overcharge point is reached, the connection between the solar panel and the battery is cut off. When the overdischarge point is reached, the connection between the battery and the load is cut off, so as to protect the battery. The storage battery is connected to a power supply output end to realize charging for the portable device.

The battery is connected to a detection module for detecting battery power, the signal output end of the detection module is connected to the solar controller, and is also connected to a power indicating device for indicating the current power of the battery. Indicates the current charge of the battery.

The output end of the power supply is connected to a USB interface to realize charging of various portable devices such as mobile phones, digital cameras, and PCs.

The output terminal of the power supply is also connected with a charging management module, and when the portable device is fully charged, the storage battery and the portable device are cut off, so as to realize the management and control of charging and protect the portable device.

The solar battery panel adopts thin-film solar cells, which have the characteristics of high conversion efficiency, low energy consumption and high stability, and conform to the development trend of thin-film, large-area and high-efficiency solar cells.

The solar cell panel adopts a monocrystalline silicon solar cell panel. The photoelectric conversion rate of monocrystalline silicon solar panels is 15% to 20%, even up to 24%.

The solar cell panel adopts a polycrystalline silicon solar cell panel. Compared with monocrystalline silicon solar panels, the cost is low.

Beneficial effects: the utility model expands the single storage function of the suitcase, realizes convenient charging of the portable device, and simultaneously makes effective use of the surface space of the suitcase.
