Patent attributes
An induction type padlock includes a shell, a lock bolt, a shackle, a driving unit, a light-emitting component, and an induction control unit. The lock bolt slides in the shell and has a recess. The shackle is inserted into the shell through the lock bolt and has a latch portion being able to be latched by the lock bolt. The driving unit rotates the position limiter in the recess; the position limiter has a wide portion and a narrow portion. The induction control unit is electrically connected to the driving unit and the light-emitting component. The induction control unit senses a signal to select the wide or the narrow portion of the position limiter to be disposed in the recess and controls the light-emitting component. Therefore, the time delay problems of unlocking and locking can be solved and the distinguishable lighting indications of unlocking and locking can be obtained.
