动力总成及车辆
By adopting a design in which the housing and engine together form an installation space in the range-extended electric vehicle powertrain, the drive motor and generator are integrated, solving the problems of a large number of parts and poor integration. This results in a powertrain that is small in size, light in weight, and highly reliable, improving manufacturing efficiency and driving performance.

AI Technical Summary
The separate layout of components in existing range-extended electric vehicle powertrains results in a large number of parts, poor integration, increased overall size and weight, and complex manufacturing and assembly.
The installation space is enclosed by the housing and the engine, integrating the drive motor and generator, reducing the number of parts and optimizing the spatial layout. The integration is improved through coaxial arrangement and modular design, and the space is separated by partitions and annular cylinders to reduce electromagnetic interference and heat transfer.
It significantly improves the integration and structural stability of the powertrain, reduces the overall size and weight, simplifies the manufacturing and assembly process, enhances durability and reliability, and improves energy conversion efficiency and driving performance.
