Abstract: An electric steering lock for a motorcycle includes a housing, a transmission assembly, a spindle, and a circuit board. The transmission assembly has an actuator, a first gear, a second gear and a sliding block each arranged within the housing in transmissive engagement with each other. The spindle is assembled with the sliding block and acts in the second space. The circuit board is arranged on the bottom of the housing. The primary control chip of the motorcycle controls the circuit board to make the transmission assembly to drive the spindle to move accordingly. The sliding block touches an inner wall of the casing to make it unable to move forwards or backwards any more. The current of the actuator at this time is larger than that in its normal operation. The rotation of the actuator is ceased by the circuit board when a variation in current of the actuator is detected by the circuit board.

Abstract: An electric steering lock for a motorcycle includes a housing, a transmission assembly, a spindle, a set of sensors and a circuit board. The transmission assembly has an actuator, a first gear, a second gear and a sliding block each arranged within the housing in transmissive engagement with each other. The spindle is assembled with the sliding block and acts in the housing. A primary control chip of the motorcycle controls the circuit board to make the transmission assembly to drive the spindle to move accordingly. The circuit board determines that the spindle is locked and reaches a predetermined position if the sliding block presses the front sensor, and the circuit board determined that the spindle is unlocked and reaches a predetermined position if the sliding block presses the rear sensor.
