Internal combustion engine type integrated generator system and automobile

Abstract

The invention discloses an internal combustion engine type integrated generator system and an automobile. The internal combustion engine type integrated generator system comprises a power battery assembly, a generator and a rotor engine, wherein the generator is electrically connected with the power battery assembly, and the generator comprises a motor main body and a motor inner rotor connected in the motor main body; an output shaft of the rotor engine is connected with the motor inner rotor, and the rotor engine is used for driving the output shaft to rotate so as to drive the motor inner rotor to rotate. According to the technical scheme, the structure of the internal combustion engine type integrated generator system can be greatly simplified, the size and the weight can be obviouslyreduced, the energy consumption of the internal combustion engine type integrated generator system is lower under the same rated output rotating speed, and energy can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of automobile generators, in particular to an internal combustion engine type integrated generator system and an automobile. Background technique [0002] A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by a generator. [0003] Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. The range-extended electric vehicle uses an internal combustion engine to drive a generator. When the battery is fully charged, the power battery drives the motor to provide the driving power demand of the vehicle. At this time...

AI Technical Summary

Problems solved by technology

[0004] Existing range-extended range extenders for electric vehicles are still driven by traditional engines to achieve range extension, which means that they have the same disadvantages as traditional reciprocating piston internal combustion engines: 1) The engine is large in size, and the conditions for matching the battery pack and engine at the same time in the range-extended electric vehicle 2) The combustion noise of the traditional internal combustion engine is relatively large, which is different from the ultra-quiet publicity concept of electric vehicles, and the use of sound insulation materials to reduce noise will lead to further increase in cost; 3) The generator is driven by belt and transmission transmission There are problems such as slipping and low transmission efficiency. At present, the speed ratio of the generator and the engine is basically within 2.5. To further improve it, it is necessary to increase the engine speed or increase the idler, etc., resulting in an increase in energy consumption and cost.
