The invention relates to an elevator car buffering device, and relates to the technical field of elevators. The buffer device comprises an elevator shaft and a lift car slidably connected into the elevator shaft, a buffer part is arranged at the bottom of the elevator shaft, a supporting frame is arranged on the lift car, a rope winding rod is rotatably connected to the supporting frame, a connecting rope is wound and fixed to the rope winding rod, and the end, away from the rope winding rod, of the connecting rope is arranged at the top of the elevator shaft. A driving assembly is arranged on the lift car, and the driving assembly is used for driving the rope winding rod to rotate, so that when the lift car descends, the connecting rope is released, and when the lift car ascends, the connecting rope is wound; a control piece is arranged on the lift car, and the control piece is used for controlling the rope winding rod to be quickly braked when the lift car breaks down and descends, so that the rotating speed of the rope winding rod is kept unchanged; the buffer effect of the buffer device on the lift car is improved.
