NEW HYBRID POWER COUPLING MECHANISM AND HYBRID POWER CONTROL METHOD AND DEVICE

摘要

Provided is a hybrid power coupling mechanism, comprising an engine (1), a range extension module (101) and a pure electric drive module (102). The range extension module (101) comprises an electric generator (6) and a first transmission device. An output shaft (3) of the engine is connected to an input shaft (7) of the electric generator through the first transmission device. The engine (1) and the electric generator (6) are arranged side by side. The pure electric drive module (102) comprises a drive motor (8), a differential mechanism (14) and a second transmission device. The drive motor (8) is connected to the differential mechanism (14) through the second transmission device. The differential mechanism (14) transmits power to wheels (19) through a drive axle (18) of an automobile. The hybrid power coupling mechanism rationally optimizes the structural layout, has low costs, and is convenient to install and maintain. Further provided is a hybrid power control method, and in the control method, a working mode of the automobile is switched according to the remaining electric quantity value of a battery and the automobile speed, so that the requirements of different working conditions are met. A hybrid power control device is also provided.
