The invention discloses a shell structure of an electric drive assembly and the electric drive assembly. The shell structure comprises a motor shell, a speed reducer shell, a controller shell, an oil cooling assembly and a water cooling assembly. At least two shells of the motor shell, the speed reducer shell and the controller shell adopt an integrated structure; the oil cooling assembly comprises an oil pumping unit and oil ducts, the oil ducts are arranged in the motor shell and the speed reducer shell, and the oil pumping unit communicates with the oil ducts and conveys lubricating oil in the speed reducer shell to the oil ducts; the water cooling assembly comprises a water channel, the water channel is a circulating water channel and is arranged in the controller shell and the motor shell, and the water channel is connected with a water cooling source of the vehicle. According to the shell structure, the weight of the electric drive assembly can be reduced, the rigidity of the electric drive assembly can be improved, and the shell structure has the advantages of being good in NVH (Noise, Vibration, Harshness, noise, vibration and sound and vibration roughness) performance and high in cooling and lubricating efficiency.
