Hybrid power assembly and vehicle

The invention discloses a hybrid power assembly and a vehicle, and belongs to the technical field of hybrid power assemblies. The hybrid power assembly comprises a differential mechanism; the driving motor is in dynamic coupling connection with the differential mechanism; the generator is in dynamic coupling connection with the differential mechanism through a speed reducer; the engine comprises a crankshaft and a cam shaft which are in dynamic coupling connection, and the crankshaft is in dynamic coupling connection with the generator through the speed reducer; the locking mechanism is mounted on the engine; and under the condition that the driving motor and the power generator both output torque to the differential mechanism, the locking mechanism locks the cam shaft. By arranging the locking mechanism to lock the crankshaft, a dual-motor driving parallel mode can be achieved, rotation of the engine is avoided in the dual-motor driving parallel mode, and the working noise of the hybrid power assembly is red
