The invention discloses an electric drive assembly structure, an electric drive assembly structure for a vehicle and the vehicle. The electric drive assembly structure comprises a shell, a first stator assembly, a second stator assembly, a rotor assembly and an output mechanism, wherein the first stator assembly and the second stator assembly are arranged in parallel, the rotor assembly is locatedbetween the first stator assembly and the second stator assembly, axial air gaps are formed between the rotor assembly and the first stator assembly and between the rotor assembly and the second stator assembly, the output mechanism is fixedly connected to the rotor assembly, and a containing cavity used for containing the first stator assembly, the second stator assembly, the rotor assembly andthe output mechanism is formed in the shell. Compared with the prior art, the electric drive assembly structure adopts a double-stator single-rotor structure, can improve the utilization rate of a motor iron core, is high in power and torque density, makes up for the power deficiency due to canceling a speed reducer, and is compact in structure, small in size and light in weight.
