Anti-theft device of electric vehicle

Abstract

The invention discloses an anti-theft device of an electric vehicle. The anti-theft device comprises an installation plate installed on a vehicle body above wheels of the electric vehicle, and a lockbody which is used for clamping a hub, the hub is installed in an electric vehicle wheel, the lock body comprises a base and a fixing plate, the base and the fixing plate are fixedly installed at thebottom of the installation plate and located on the two sides of the hub, and a lock cylinder and a fixing piece which match each other are installed in the base. A key is used for screwing the lock cylinder, the lock cylinder drives a bevel gear to rotate, a lead screw and a moving block drive multiple lock rods on a moving plate to move till the top ends of the lock rods penetrate through the hub and are inserted into connecting grooves, then the key is pulled out, the lock rods can penetrate through the hub on the wheel of the electric vehicle to clamp the hub, and the electric vehicle is prevented from being stolen. Compared with a traditional electric vehicle lock, the anti-theft device which uses the bevel gear and the lead screw for meshing transmission has the advantages that the structure is more stable, and the lock rods can be prevented from being separated from the connecting grooves.
