Abstract: An electric assembly includes: a box assembly, a motor, and a transmission. A mounting plate is disposed in the box assembly and divides a space within the box assembly into a motor holding cavity and a transmission holding cavity arranged along an axial direction of a motor shaft. The mounting plate has a shaft via-hole making the motor holding cavity and the transmission holding cavity be in communication. The motor is disposed in the motor holding cavity. The transmission is disposed in the transmission holding cavity. The motor is power-coupled to the transmission. At least one of a surface of the mounting plate facing the motor and a surface of the mounting plate facing the transmission is provided with ribs including strip-shaped ribs extending along a radial direction of the motor. Heights of the strip-shaped ribs decrease from a center portion of the mounting plate to a periphery portion of the mounting plate.
