The present invention discloses an elevator car mechanical door lock, an elevator door motor and a car door system. The elevator car mechanical door lock comprises a rotating hook device, a servo hook, a push rod assembly, a limiting plate and a floor door baffle plate, wherein the rotating hook device is installed on a door motor cross beam, does not move along with car doors, and can rotate with respect to the door motor cross beam around a rotating center of the rotating hook device; the servo hook moves along with the car door; the push rod assembly moves along with one or the other car door; the floor door baffle plate is installed at a landing side of a flat bed zone of the elevator car and stands still; and the limiting plate is installed on the door motor cross beam, does not move along with the car doors, and limits a rotating angle of the rotating hook device when the elevator car is at a non-flat bed. When the elevator car is at the flat bed, the elevator car door lock does not impact door opening and closing actions; and when the elevator car is at the non-flat bed, the elevator car door lock can prevent people in the elevator car from opening the elevator car by a large gap. An elevator door motor with the elevator car mechanical door lock, and a car door system using the elevator door motor are also disclosed.
