The invention discloses a device enabling a car door sill to align at a landing door sill. A bracket is connected to the upper portion of an upper car platform in a rigid or detachable mode and connected with a motor support in a rigid or detachable mode; one or more ultrasonic motors are fixedly connected to the motor support respectively; main shafts of the ultrasonic motors are connected with a micro-positioning platform connected to a car floor through one or more springs; a position sensor is arranged on the side of the car door sill and electrically connected with the ultrasonic motors. The relative position precision of the car door sill and the landing door sill is higher; influences caused by insufficient micro-positioning platform layer precision and faults can be eliminated; through fine motion of a car, a car frame is fixed, a main machine brake does not need to be released in the platform layer, and safety when a door is opened in an elevator leveling area; a few transmission chains are provided for the device; the system response is rapid; the transmission precision is high, working efficiency is high, interference is low, and the signal attenuation rate is low.
