Problems solved by technology

[0002] At present, the lowest power supply voltage of electric bicycles is 24 volts. Due to technical reasons, the power supply voltage of commonly used electric bicycles is 36 volts or even 48 volts, and the weight exceeds 40 kilograms, and the volume is very large, so it is impossible to be used in vehicles.

Embodiment Construction

[0010] exist figure 1 Among them, the voltage of the battery 1 is 12 volts, which is the same as the battery used in the car. In this way, the vehicle-mounted harmonic electric bicycle can use the car's own charging system to charge when the car is running, and the electric bicycle can be used when the car stops. The controller 2 adds a power management function. When the battery power is lower than the car power supply, the battery is charged by the car charging system.

[0011] exist figure 2 Among them, the motor 4 adopts a 12-volt ultra-low voltage. In order to provide sufficient torque to the electric bicycle, a harmonic reducer 5 with a large reduction ratio is used. The electric power and manpower are synthesized by the power synthesis mechanism 6 to drive the vehicle. Under the premise of ensuring the most comfortable riders, the output power of the motor is reduced to the greatest extent, so the same effect as that of ordinary electric bicycles can be obtained by us...

Abstract

The invention relates to a bicycle-mounted harmonic electric bicycle and relates to a bicycle-mounted electric bicycle. The power voltage of the electric bicycle is reduced to 12 V, the electric bicycle can be directly charged through an inner direct current charging system of an automobile, and the bicycle-mounted electric bicycle becomes a genuine automobile ancillary facility. In order to achieve the purposes that the sufficient torque can be provided under the ultra-low voltage, the weight is lower, the size is smaller, and the bicycle can be conveniently carried on the automobile, a special drive device is adopted and includes a 12 V high-speed motor rotating 3000 turns per minute, a 1:60 large-speed-ratio harmonic reducer and a double-surpass power combining mechanism. In the reality that the automobile is parked more and more difficultly, the bicycle-mounted harmonic electric bicycle will become an essential ancillary facility of the automobile, and great social benefits and economic benefits are generated.

Description

technical field [0001] The invention relates to a vehicle-mounted harmonic electric bicycle, which relates to a vehicle-mounted electric bicycle. Background technique [0002] At present, the lowest power supply voltage of electric bicycles is 24 volts. Due to technical reasons, commonly used electric bicycle power supply voltages are 36 volts or even 48 volts, and they weigh more than 40 kilograms and are very large, so they cannot be used in vehicles. Contents of the invention [0003] The technical solution adopted in the present invention is: the power supply voltage of the electric bicycle is reduced to 12 volts, which can be directly charged by the DC charging system inside the car, in order to provide sufficient torque under ultra-low voltage and to be lighter in weight and smaller in size, convenient Carry, the present invention adopts special driving device: 12 volts per minute 3000 rpm high-speed motor, 1:60 large speed ratio harmonic reducer and double transcend...
