The invention provides a floor profile structure, a floor and a railway vehicle. The floor profile structure comprises at least one floor unit, at least one air passing cavity is formed in each floor unit, the two ends of each air passing cavity are suitable for being arranged at the first-position end and the second-position end of a vehicle body in a penetrating mode respectively, and air is suitable for being introduced into each air passing cavity. According to the floor profile structure, the air passing cavity is directly formed in the floor unit, ventilation is achieved in the air passing cavity, and the two ends of the air passing cavity penetrate through the vehicle body, so that the air passing cavity is used for replacing an original air passing pipeline independently arranged under the vehicle, the occupied space of the pipeline under the vehicle is saved, the pipeline weight is reduced, the paving operation process of the pipeline under the vehicle is shortened, and therefore, the lightweight design of the vehicle is realized.

    本发明提供一种地板型材结构及地板、轨道车辆。该地板型材结构包括至少一个地板单元,每个地板单元内设置有至少一条走气腔,各条走气腔的两端适于分别贯通设置在车体的一位端和二位端,且每条走气腔内均适于通入气体。该地板型材结构通过将走气腔直接构造于地板单元中,并且实现走气腔内部通气、两端贯通车体,从而利用走气腔替代原有车下单独设置的走气管路,节省车下管路占用空间,减少管路重量,并减少车下管路铺装操作过程,从而实现车辆轻量化设计。
