Some embodiments of the present disclosure provide a hybrid power coupling mechanism and a vehicle. The hybrid power coupling mechanism includes an engine, a first output shaft, a generator, a driving motor, and a differential mechanism, wherein a rotating shaft of the engine is connected to an input shaft of the generator through the first output shaft, and an input shaft of the driving motor is connected to the differential mechanism in a speed-reducing manner through a planetary gear set. The vehicle includes a power storage battery, a motor controller and the foregoing hybrid power coupling mechanism. The problems of power interruption and high cost in mode switching of a hybrid power coupling mechanism of the existing vehicle are solved. The engine and the generator operate in an extended range mode, and the driving motor is decelerated by the planetary gear set and inputs power to the differential mechanism.
