The invention discloses a collision avoiding structure of a safety footboard of a rail transit platform. The structure comprises a movable push rod 511 and an L-shaped rotating bracket 901, wherein the movable push rod 511 is mounted at one end of a cross beam at the front end of a movable frame, and telescopically moves along the cross beam; the two ends of the bracket 901 are respectively in sliding connection with a fixed frame base and the movable push rod 511; the turning end of the bracket 901 is rotationally connected with a sliding frame; and the horizontal thrust of the movable rod 511 is converted to the inward tensile force on the sliding frame by the bracket 901. Through the collision avoiding structure, once the emergency that a train runs into the platform and the footboard does not retreat occurs, the head of the train collides with the movable push rod and generates a strong thrust, and the thrust is automatically converted to the inward tensile force of the sliding frame through the L-shaped rotating bracket. Therefore, the sliding frame and the footboard retreat back to the fixed frame base to prevent further collision between the train and the footboard. Thus, all possibilities of damaging the rail transit train or generating adverse effect on the operation of the train are prevented as far as possible. |
