The invention relates to the technical field of railway vehicles, in particular to a boarding step structure, a vehicle body and a railway vehicle. The boarding step structure is installed in a boarding space formed at the disconnected position of an edge beam. The boarding step structure comprises a reinforcing beam and at least one pair of connecting beams, the two ends of the reinforcing beam are fixedly connected to the bottoms of the edge beams through the at least one pair of connecting beams respectively, and each pair of connecting beams are located at the two ends of the disconnectedpositions of the edge beam respectively. And a first tread matched with the boarding space is formed on the upper surface of the reinforcing beam. According to the boarding step structure, the bearingstrength of the bottom frame at the door area position can be improved, the boarding space is reinforced, and therefore the boarding and alighting safety of passengers is improved.

    本发明涉及轨道车辆技术领域,尤其涉及登车台阶结构、车体及轨道车辆。该登车台阶结构安装于边梁的断开位置处形成的登车空间中。该登车台阶结构包括补强梁以及至少一对连接梁,补强梁的两端分别通过至少一对连接梁固接于边梁的底部,并且每对连接梁分别位于边梁的断开位置两端;补强梁的上表面形成有与登车空间相匹配的第一踏面。本发明的登车台阶结构能够提高底架在门区位置的承载强度,对登车空间起到了加固作用,从而提高乘客上下车的安全性。
