Mobile charging device based on solar energy

Abstract

The invention discloses a mobile charging device based on solar energy, comprising a housing and a USB interface. The top part of the housing is provided with a groove, and the inner wall of the groove is connected to a solar cell panel. The solar cell panel is connected to a processing device and an energy storage device through leads, and the processing device and the energy storage device are both disposed in the housing. One side of the groove is provided with a display device, and the other side of the groove is provided with a control panel. The display device and the control panel are both disposed at the top part of the housing. The control panel is provided with an alarm device, an indication lamp and a switch. The inner wall of the housing is connected to a fixed rod, which is connected to a roller in a rotating manner. The roller is provided with a protection cloth in a winding manner, and one side of the protection cloth is connected to a fixed column. The invention is advantageous in that the structure is simple, operation is convenient, and cost is quite low; the protection cloth on the housing can provide protection for the USB interface; the mobile charging device can conduct charging by means of the solar energy.
