The invention provides a double anti-theft mechanism of an electromobile, and belongs to the technical field of vehicle anti-theft. The double anti-theft mechanism of the electromobile solves the problem that an anti-theft structure of an existing electromobile is too complex, and an electric door lock is prone to being pried open by a screwdriver. According to the double anti-theft mechanism of the electromobile, the outer cylinder surface of the lock road of the electric door lock is fixedly connected with a first-class anti-theft shell in the radial direction, the first-class anti-theft shell is internally and fixedly provided with a central positioning column, the central positioning column is sleeved with a first-class anti-theft locking plate which can rotate on the central positioning column and rotate to the locking opening of the electric door lock to cover the locking opening of the electric door lock, and a first-class anti-theft lock body is provided with a first-class anti-theft locking-tongue which can enable the first-class anti-theft locking plate to enter or exit from the locking opening of the electric door lock. The double anti-theft mechanism of the electromobile is simple in structural design, ingenious in structure, and double anti-theft effects are achieved.
