Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

A solar mobile phone charging pile, the structure of which is shown in Figure 1. It includes a vertical rectangular box body 1, the top of the box body 1 is installed with a solar panel 2 through a bracket, the box body 1 is provided with a controller 3, a storage battery 4, a charging control board 5 and a charging room 6 with a charging line, the charging room LED lights 7 are arranged on the top wall.

The solar panel 2 is connected to the storage battery 4 through the controller 3, and the controller converts the solar energy collected by the solar panel into electrical energy and then stably outputs it to the storage battery for charging.

The input end of the charging control board 5 is connected with the output end of the controller and the output end of the storage battery respectively, a switch for controlling voltage output is arranged between the output end of the storage battery 4 and the charging control board 5, and the output end of the charging control board 5 is connected with the output end of the charging control board 5 respectively. The charging line 8 is connected with the LED lighting lamp 7 .
