The invention discloses a roof side cover plate structure and a low-floor railway vehicle, belongs to the technical field of low-floor railway vehicle roof design, and aims to solve the problems that in the prior art, the connection reliability of a side cover plate and the top of a vehicle body is low, and the connection point of the side cover plate and the top of the vehicle body is prone to abrasion and mechanical fatigue. The side cover plate fixing structure comprises the following steps: reliably fixing a side cover plate relative to the top of a vehicle body through the matching of a limiting clamping groove and a limiting buckle, the supporting of a detachably connected supporting elastic block and the matching of a spring buckle and a buckle hole; the supporting elastic block can absorb mechanical energy generated by shaking of the side cover plate, matching of the limiting clamping groove and the limiting buckle and matching of the spring buckle and the buckle hole belong to non-tight connection, a certain shaking and vibration redundant space exists, and the influence of running bumping and shaking of the side cover plate on the mechanical life and fatigue of the side cover plate is small.

    本发明公开了一种低地板轨道车辆车顶设计技术领域的车顶侧罩板结构及低地板轨道车辆,旨在解决现有技术中侧罩板与车体顶部的连接可靠性不高、侧罩板与车体顶部的连接点容易磨损和产生机械疲劳的问题。其包括通过限位卡槽与限位卡扣的配合、可拆卸连接的支撑弹性块的支撑、弹簧卡扣与卡扣孔的配合,可靠的将侧罩板相对于车体顶部固定;支撑弹性块可以吸收侧罩板的晃动产生的机械能,限位卡槽与限位卡扣的配合以及弹簧卡扣与卡扣孔的配合属于非紧密连接,存在一定的晃动与振动冗余空间,行驶颠簸与侧罩板晃动对其机械寿命和疲劳的影响较小。
