The invention relates to a charging device for an electric driving tool. The charging device comprises a generator, an impeller rod, blades, a speed limiting safety mechanism, a power inverter and anair duct. One end of the impeller rod is connected with the generator, the other end of the impeller rod is connected with the speed limiting mechanism, and a plurality of aerodynamic rotating bladesare arranged on the impeller rod at intervals; the generator is connected with the power inverter; the end, away from the generator, of the air duct is provided with an air inlet circumferentially, and the other end of the air duct is provided with an air outlet. The charging device is arranged on the electric driving tool, in the driving process, after wind enters the air inlet of the air duct, the impeller rod is driven to rotate under the action of the blades, and the generator converts a direct current with uncertain frequency into an alternating current with the same frequency as a powergrid through the power inverter. Therefore, the charging device can generate torque under the action of advancing power to drive the wind wheel to rotate in the traveling process of the electric traveling tool, the generated electric energy charges the electricity storage power source, and the charging device is environmentally friendly.

    本发明涉及一种用于电动行驶工具的充电装置,包括发电机、叶轮杆、叶片、限速安全机构、电源逆变器和风筒;叶轮杆的一端与发电机连接,叶轮杆的另一端与限速机构连接,叶轮杆上间隔设有多个空气动力外形的转动叶片;发电机与电源逆变器连接;风筒远离发电机的一端延其周向设有进风口,风筒的另一端设有出风口。通过将充电装置设置在电动行驶工具上,在行驶过程中,风进入风筒的进风口后由于叶片作用带动叶轮杆转动,发电机经过电源逆变器将频率不定的直流电转化成与电网同频率的交流电。因此,本发明的充电装置能够在电动行驶工具行驶的过程中,在行进动力作用下产生力距驱动风轮转动,产生的电能对储电电源进行充电,绿色环保。
