Patent number: 10859098Abstract: The present invention provides a drive device including a drive motor. The drive motor includes an end cover, a motor housing, a stator, a rotor, a motor shaft, and a bearing. The drive motor further includes a casing and a first heat-dissipating fan used for dissipating heat for the motor housing. The casing is fixedly mounted on a side of the end cover to contain the motor housing into a chamber formed by the casing. The casing and the motor housing are spaced apart at certain intervals to form a gap between the casing and the motor housing for air flow to pass through. The first heat-dissipating fan is connected to the end of the motor shaft away from the end cover to rotate with the motor shaft. The casing is provided with an air inlet and an air outlet for air flow to pass through.Type: GrantFiled: December 27, 2018Date of Patent: December 8, 2020Assignee: Zhejiang Dongxin iTechnology Co., Ltd.Inventors: Fengping Zhou, Xinjiang Zhou, Guoyao Wu, Xiaoke Zhou, Dong Chen
