Rail train platform expansion footboard device

Abstract

A rail train platform expansion footboard device comprises a base plate, bearings, an expansion plate, a cover plate, a driving motor, an external-thread pull bar, and an elastic strip. The expansionplate with the bearings at the bottom are arranged at the top of the base plate. The elastic strip is fixed to the front of the expansion plate. When the expansion plate is extended out, the elastic strip is in contact with the lower edge of a train compartment doorway; the cover plate is arranged at the top of the expansion plate, and the cover plate is fixedly connected with the left wall, rightwall and rear wall of the base plate; a spindle of the driving motor fixedly connected to the rear wall is fixedly connected with the external-thread pull bar; the external-thread pull bar is connected with an internal-thread nut fixed at the rear of the expansion plate; when a spindle of the driving motor rotates forwardly or reversely, the external-thread pull bar drives the expansion plate fixedly connected with the internal-thread nut to slide forward or backward. The rail train platform expansion footboard device has the advantages that when a train arrives, the expansion plate is extended out to block a gap between the platform and the train; after train doors and platform railing doors are opened, people may safely step on the expansion plate to move in or out, small articles thatare dropped never fall into the gap, and children's feet never step into the gap.

AI Technical Summary

Benefits of technology

This technology prevents things from falling through gaps on both platforms and trains during stops or starts without causing any problems for passengers who enter them.

Problems solved by technology

The technical problem addressed by this patented technology relates to preventing foreign object from entering these gaps during opening up when moving vehicles like cars onto rails that have an elevated surface called a railway track system (also known as a type of transportation). This can lead to significant loss if dropped items get stuck inside through them.
