The invention discloses an automatic escape device for a lift car. The automatic escape device comprises a roller seat, wherein a roller is fixedly arranged on the roller seat; a steel wire rope is wound on the roller; a timer and a motor for driving the roller to rotate positively and negatively are further arranged on the roller seat; the timer, the motor and a flat-bed sensing switch arranged on the lift car are electrically connected together. A counter is used for sensing the trigger time interval of the leveling switch in order to judge whether a lift fails or not, and the motor is triggered to control the lower part of the steel wire rope to open a lift door when the lift car arrives at a nearest flat bed, so that the situation of failure in automatically escaping when a brake or a host and the like fails is avoided.
