The invention discloses an asynchronous door knife with a car lock. When a second unlocking blade device is suffered from the driving force in the door opening direction, a poking rod of the second unlocking blade device moves to the door opening direction, and drives a lever wheel component to rotate; when the lever wheel component rotates, a first unlocking blade is pushed to swing to the unlocking direction under the guide effect of a guide mechanism; and the first unlocking blade drives a rotating hook of a rotating latch component to rotate to the unlocking direction, so that the rotating hook of the rotating latch component is released from a fixed hook, and the rotating latch component is unlocked. The asynchronous door knife has the functions of opening the car lock and connecting/disconnecting the opening/closing of the door in place; the car lock is unlocked without arranging such additional mechanisms as a landing door battledore on a landing door device; and in emergent rescue on a flat floor, a landing door is opened, and the unlocking of the car lock is synchronously finished. The invention further discloses an elevator door motor having the asynchronous door knife with the car lock, and a car system adopting the elevator door motor.
