[0003] The invention relates to a power anti-theft switch lock used on an existing electric vehicle. When a key that fits the insert is inserted into the lock core, the insert returns to its original position, and the lock core return spring pushes the lock core connecting rod, so that the anti-theft pin and the lock core connecting rod return to their original positions in the lock core, thereby turning on the power. When a key that does not fit the insert is inserted into the lock core, the insert cannot return to its original position, and the lock core anti-theft pin pushes the lock core connecting rod out of the lock core so that it remains in the lock shell. The lock core connecting rod cannot be connected to the lock core, so that the lock core rotates infinitely, thereby achieving the purpose of anti-theft. There is also a power anti-theft switch lock used for electric vehicles or motorcycles. The switch gear slot and the lock faucet gear slot are not in the same groove. Even if an unsuitable key opens the faucet lock by chance, it still needs to hit the switch gear slot to turn on the power. Multiple insurances are provided to prevent the vehicle from being stolen.

10. A control system for a power lock for an electric vehicle, characterized in that: A power lock for an electric vehicle according to any one of claims 1 to 9 is used, comprising the following steps: S1. First, when the handlebar of the electric vehicle is rotated, the strong and weak signals outputted from the handlebar are converted into driving signals for driving the power tube, and the power tube provides corresponding current to operate the motor (27), and the output end of the motor (27) drives the driving rod (5) to rotate, and the driving rod (5) drives the sprocket (6) located on one side thereof to rotate, and the sprocket (6) drives the chain (7) to transmit, and the chain (7) drives the sprocket (6) on the other side to rotate, and the sprocket (6) drives the rotating rod (4) to rotate, and the rotating rod (4) drives the rear wheel (1) of the electric vehicle to rotate, thereby driving the electric vehicle to move; S2. When the electric vehicle is parked, a signal is transmitted through the controller (31), and the wireless module (32) transmits the electrical signal to the single-chip computer module (30) for processing. The single-chip computer module (30) converts the wireless signal into an electrical signal, and then transmits it to the motor (27) and the multi-section electric push rod (28). The motor (27) stops running, and the multi-section electric push rod (28) pushes the rotating seat (13) to move through the pushing plate (29). The rotating seat (13) drives the two rotating plates (14) to rotate between the rotating seat (13) and the rotating table (15). The rotating table (15) slides on the slide rail (8), thereby driving the two clamping plates (9) to approach each other. At the same time, when the rotating seat (13) moves, it drives the rack (23) to move. The rack (23) The movement of the gear (23) drives the gear (24) to rotate, the rotation of the gear (24) drives the rotating shaft (20) to rotate, the rotation of the rotating shaft (20) drives the worm wheel (21) to rotate, the rotation of the worm wheel (21) drives the worm (22) to rotate, the rotation of the worm (22) drives the rotating screw (17) to rotate, the rotation of the rotating screw (17) drives the threaded cylinder (16) to move, the threaded cylinder (16) drives the locking plate (11) to move, so that the locking plate (11) is close to the rear wheel (1) of the electric vehicle, the locking plate (11) is tightly attached to the rear wheel (1) of the electric vehicle, and then cooperates with the two clamping plates (9) to clamp the rear wheel (1) of the electric vehicle, and tightly holds the rear wheel (1) of the electric vehicle, thereby preventing the rear wheel (1) of the electric vehicle from rotating.
