The invention provides a disconnecting mechanism of a vehicle electric driving system and an automobile. The disconnecting mechanism comprises a shell, a first rotating shaft, a second rotating shaft, a spline housing and a power mechanism. The shell is in butt joint with the speed reducer shell. One end of the first rotating shaft extends into the speed reducer shell and is connected with an output shaft of the differential, and the other end is provided with a first external spline part and is positioned in the shell; the second rotating shaft is arranged in the shell, and one end of the second rotating shaft is provided with a second external spline part butted with the first external spline part; the second rotating shaft is connected with a driving half shaft; the spline sleeve is sleeved outside the first rotating shaft and the second rotating shaft, is meshed with the first external spline part and the second external spline part, and can move along the axial direction; the power mechanism drives the spline housing to move in the axial direction. The differential mechanism is integrated between the output shaft and the driving half shaft of the differential mechanism, the problem that a permanent magnet synchronous motor of an electric driving system is reversely supported can be fundamentally solved, and the differential mechanism can serve as an independent modular structure, is suitable for different four-wheel-drive electric automobiles or hybrid automobiles and is convenient to disassemble and maintain.
