The invention discloses an asynchronous door knife having a car door lock; when a second unlocking blade device is suffered from the driving force in the door opening direction, the second unlocking blade device drives a swinging rod arm to rotate; the rotation of the swinging rod arm drives a guide mechanism to swing; the swinging of the guide mechanism drives a first unlocking blade to swing; the first unlocking blade drives a rotating hook of a rotating latch component to rotate to the unlocking direction after swinging, so that the rotating hook of the rotating latch component is released from a fixed hook, and the rotating latch component is unlocked; and meanwhile, the rotation of the rotating hook drives a driving door switch trigger to rotate, so that an electric contact of a beating plate type driving door switch is cut off. The asynchronous door knife has functions of opening the car door lock and opening/closing the door in place, and synchronously finishes the unlocking of the car door lock while opening a landing door in emergency rescue of a flat floor. The invention further discloses an elevator door motor having asynchronous door knife with the car door lock and a car door system adopting the elevator door motor.
