Abstract:
A platform door, comprising at least one set of sliding door mechanisms; each sliding door mechanism comprises four guide rails (20) arranged in parallel with each other, the four guide rails (20) being located on the same horizontal plane; each guide rail (20) is slidably provided with a movable door body (10), there being a contact fit between movable door bodies (10) on adjacent guide rails (20); each guide rail (20) has a transmission connection with a driving assembly used to drive the movable door body (10) to move back and forth along a length direction of the guide rail (20). By means of arranging four parallel guide rails (20), and slidably providing each guide rail (20) with a movable door body (10), each movable door body (10) not interfering with the adjacent movable door body (10), the four movable door bodies (10) can form a continuous long-distance electric door-moving mechanism and can be opened at any position, which is suitable for special working conditions having flexible and varying door opening requirements; the mechanism can meet the requirements of parking errors and different car types, and has high usability.
