Portable wind power generation device

Abstract

The invention relates to a portable wind power generation device. A USB charging port is arranged in an outer wall of a lower shell. A lower bearing is arranged in a center of an internal portion of the lower shell. A motor stator located in the lower shell is arranged outside the lower bearing, and a stator winding is arranged on the motor stator. A motor rotor located at an upper end of the lower bearing is arranged in the motor stator, and a rotor winding is arranged on the motor rotor. The rotor winding is connected with a rectifier bridge in the USB charging port. A foldable wind power rotating component is arranged at a top of the motor rotor. An upper bearing is arranged at the top of the wind power rotating component. The upper bearing is arranged in an upper shell. In the invention, wind power generation is miniaturized and the device is made into a portable charging device, a portable folding design is adopted, advantages of a small size, light weight, easy installation and maintenance-free performance are possessed, portability is greatly improved, and charging requirements of a mobile phone, a computer, a power bank and the like can be provided anytime and anywhere.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a portable wind power generating device. Background technique [0002] With the advancement of human science and technology, electric energy is an indispensable energy basis. People have an inseparable relationship with electricity, electronics, and electrical appliances. For example, people need mobile phones to surf the Internet and make calls anytime and anywhere. Charging, exploring remote mountains and forests, outings, mobile phones or portable electronic devices need to be powered. [0003] At present, portable solar backpacks or panels can only be used when there is sunlight, but they cannot be used at night or on cloudy days without sunlight; in addition, some wind power is used to generate electricity, but the existing wind turbines require professional installation , at least more than ten kilograms, it needs a professional tower and a battery to use it...
