The invention provides a rear brake locking device of an electric vehicle. The rear brake locking device comprises a chain box, a lock cylinder, a driving gear, a transmission gear, a driven gear, a rear brake wire and a rear brake wire restriction part, wherein the lock cylinder is fixed on the chain box and a rotatable part of the lock cylinder is fixedly provided with the driving gear; the transmission gear is fixed on two side walls of the chain box through a first rotary shaft and is engaged with the driving gear; the two ends of the rear brake wire restriction part are rotatably fixed on inner walls at two sides of the chain box respectively; the driven gear is fixed on the rear brake wire restriction part and is engaged with the transmission gear; the rear brake wire passes through a through hole which is vertically crossed with the rotary axis of the rear brake wire restriction part. With the adoption of the technical scheme, the rear brake locking device is located in the chain box and is prevented from being damaged by enforced external force; after the device is locked, the rear brake wire is at a stretched state all the time so that a rear wheel cannot rotate and high-speed rotation of the rear wheel is prevented under the condition that the electric vehicle is locked.
