The invention relates to an automatic anti-pinch door device. The automatic anti-pinch door device comprises a shell, a swing hammer, a swing arm, a swing brake and a support spring, wherein the swing hammer is hinged to the swing arm; the swing arm is connected with the shell; the swing brake is in movable fit and connected with the shell; the swing brake is positioned below the swing hammer; the swing brake is positioned at the position of the swing track of the swing hammer; a baffle is arranged on the swing brake; the baffle plate is opposite to the swing hammer; the swing brake is supported on the support spring; the support spring is mounted at the bottom of the shell; the upper end face of the swing brake is an inclined face, and is opposite to the swing hammer; the swing arm is a rigid swing arm, a ball joint is arranged on the swing arm, one end of the swing arm is connected with the ball joint, the ball joint is connected with the shell, a rolling shaft is arranged at the other end of the swing arm, a shaft hole is formed in the swing hammer, and the rolling shaft of the swing arm is in movable fit and connected with the shaft hole of the swing hammer; when the automatic anti-pinch door device is used, the swing hammer is driven to roll the upper end face of the swing brake by utilizing the inertia force of the swing hammer, the swing brake is driven to descend to be in contact friction with the floor, and frictional force is utilized for preventing a movable door from being closed quickly, so that the movable door is effectively prevented from pinching children.
