The invention discloses an automatic safety door device. The automatic safety door device comprises a liquid storage container and a braking container, wherein the liquid storage container is provided with a liquid overflow opening; the braking container is provided with a liquid inlet; the liquid overflow opening of the liquid storage container is communicated with the liquid inlet of the braking container; the liquid storage container is provided with fluid; the fluid comprises water or oil; the braking container is made of a flexible nonmetallic material. When the automatic safety door device is used, the automatic safety door device is installed on the bottom of a movable door, so that a clearance is formed between the bottom end surface of the braking container and the ground; when the movable door is closed rapidly, the fluid of the liquid storage container is inflated into the braking container by utilizing the inertia of the movable door in rapid close, the weight of the braking container is increased, and the braking container is lowered, so that the braking container is in contact with the ground and is abraded so as to prevent the movable door from being closed rapidly to avoid the condition that the movable door clamps children.
