Oil pipe for high-speed shaft and electric drive device

The invention provides an oil pipe for a high-speed shaft and an electric drive device, and relates to the field of mechanical design, the oil pipe comprises a pipe body, a first boss and a second boss which are coaxially arranged, the first boss is supported on the hole wall of a lightening hole of the high-speed shaft, and the second boss is sleeved with a sealing ring; the sealing ring is used for being in sealing fit with the hole wall of a lightening hole of the high-speed shaft. A pipe cavity of the pipe body is used for guiding oil liquid to a motor rotor; the pipe body is provided with a backflow structure, and the backflow structure is used for preventing oil liquid leaking to the position between the first boss and the second boss from the sealing ring from affecting the dynamic balance of the high-speed shaft. According to the structural design of the oil pipe, oil leaking into the inner hole from the sealing ring can be discharged in the process of synchronous rotation with the high-speed shaft, a
