However, due to the limitations of the functions and structures of the existing above-mentioned hub motors, its role is limited to providing power sources for electric bicycles, and does not undertake the role of power generation. Power supply, and the use of DC motor batteries to power lighting fixtures consumes more power of the DC motor batteries, resulting in a decrease in the life of the DC motor batteries, which greatly reduces the endurance of the DC motor batteries
It can be seen that the potential of the existing hub motors has not been well utilized, and the internal space has not been well utilized

The invention discloses a hub power-generating motor. The hub power-generating motor comprises a main shaft, a hub shell, a motor, a gear speed-reducing mechanism, a clutch and a hub end cover, wherein the hub shell is assembled on the main shaft by a bearing; the motor is arranged in the hub shell; and the hub end cover is fixed with the hub shell. The hub power-generating motor is characterized in that the hub shell is also internally provided with a mini-type generator which comprises a generator stator and a generator rotor; and the generator stator is fixed on the main shaft, and the generator rotor is fixed on the hub end cover. According to the hub power-generating motor, actually,the mini-type generator is additionally arranged in the conventional hub motor, and the mini-type generator works while the hub motor works normally and can generate 6-V power which is led out by a power line for supplying to a vehicle for illumination, so that the purposes of saving the electric power of a battery of the conventional direct-current motor and increasing the full charge endurance of the battery of the direct-current motor are achieved, and the service life of the battery of the direct-current motor also can be prolonged to a certain extent.
Description
technical field [0001] The invention relates to a hub motor, in particular to a hub generator motor capable of generating electricity by itself to supply electric bicycle lighting. Background technique [0002] At present, the hub motor assembled on the electric bicycle usually consists of a main shaft, a hub shell mounted on the main shaft through bearings, a motor inside the hub shell, a gear reduction mechanism, a clutch, and a hub end cover fixed to the hub shell. The gear reduction mechanism is mainly composed of a sun gear fixed on the motor rotor and a planetary gear meshed with the sun gear, and an inner ring gear meshed with the planetary gear is fixed on the inner wall of the hub shell, so that the hub shell can be driven by the motor. Drive rotation. The clutch and the planetary gear are assembled on a through shaft. [0003] When the in-wheel motor works specifically: the DC motor battery is used to power the motor to drive the motor rotor to rotate, and the mo...
