The utility model relates to a charger, which specifically relates to an automatic charger of a pull-rod document suitcase which collects the functions of automatic charge and power supply generation into integration, saves public electric energy, has the characteristics of no pollution and environmental protection as well as generates the power supply when people uses the pull-rod suitcase unconsciously, stores the power supply for using, realizes that mechanical energy is automatically converted to the electric energy, consequently realizes the functions of automatic charge and power supply of the desige, has convenient and agile use, thoroughly embodies humanization characteristics and automatically generates the power supply. The utility model comprises a pull-rod base, a rotating shaft and a roller on the front side of the pull-rod base. The utility model is characterized in that the utility model also comprises a generator, an accumulator and a specific boosting/voltage stabilizing component set; the generator is built in the base and is driven by the rotating shaft; the accumulator is connected with the generator and is provided with a power supply output jack; the boosting/voltage-stabilizing component set is connected with the accumulator; the rotating shaft drives the generator in a gear transmission mode or a belt transmission mode. |
