Driving motor with anti-falling function for electric vehicle

Abstract

The utility model relates to the technical field of driving motors, in particular to an electric vehicle driving motor with an anti-falling function, which comprises a driving motor. When the mounting disc is tightly attached to the fixing disc and the ratchet part in the mounting disc slides into the ratchet groove, the hexagonal nut cannot rotate due to the fact that the mounting disc is tightly attached to the fixing disc when the hexagonal nut is rotated forwards, and the hexagonal nut cannot rotate due to the fact that the ratchet part is matched with the ratchet groove when the hexagonal nut is rotated backwards, so that the hexagonal nut is prevented from falling off. When the hexagon nut needs to be disassembled, a pressing column is pressed, the pressing column drives a limiting plate to extrude the left side of a transverse plate, the right side of the transverse plate is lifted upwards, a ratchet part is pulled through a pull rope, and therefore a rotating plate rotates upwards to be retracted into a square groove, the hexagon nut can be screwed off through an external tool, operation is simple, and the disassembly is convenient. After being installed, the hexagon nut is high in stability, not prone to falling off and high in safety.
