The invention relates to an automobile gate pole, in particular to a road gate pole with an anti-collision automatic protection device. The road gate pole comprises a cabinet and a gate pole, wherein a motor, a speed reducer and a controller are arranged inside the cabinet; the gate pole is sleeved with an output shaft of the speed reducer; the anti-collision automatic protection device is arranged at one end of the gate pole sleeved with the output shaft, and comprises a connecting bracket, an electromagnet, a permanent magnet, a pole-colliding signal switch and a limiting block; the gate pole is fixed on the connecting bracket through a rotating shaft; the limiting block is fixed with the connecting bracket; and an opening of the limiting block and the connecting bracket defines the rotating range of the gate pole. The road gate pole has the advantages that: when the gate pole is collided, the gate pole is separated from a pole-colliding signal position switch to form an electric signal, so the electromagnet on the connecting bracket generates the same polarity as the permanent magnet, the same polarity repels, and the polarity of the electromagnet accelerates to pop the gate pole backwards to the limiting block. Meanwhile, the gate pole is accelerated to pop backwards rapidly, so that the gate pole cannot be broken by the automobile and the motor cannot be damaged.
