The invention belongs to the field of rail transit vehicle equipment floor structures, and discloses a rail vehicle floor supporting seat which comprises a top face attached to a floor and a seat body mounted in a mounting groove of a floor underframe. The mounting groove is defined by a mounting bottom plate and two clamping parts which are symmetrically arranged on the mounting bottom plate and protrude out of the mounting bottom plate; an accommodating cavity is formed in the seat body; the accommodating cavity comprises a connecting wing attached to the lower end of the top face and a side face section connected with the connecting wing and pre-bent inwards, and after installation, the top end of the clamping part of the floor bottom frame and the connecting wing are arranged in a clearance mode; the width of the gap is larger than the deformation amount of the supporting seat in the vertical direction, and the deformation amount of the supporting seat in the vertical direction is the ratio of the working load in the vertical direction to the linear rigidity of the supporting seat. By changing the structure of the supporting seat, effective installation of the floor supporting seat and the floor bottom frame is achieved. The top end of the clamping part of the floor bottom frame and the connecting wing are arranged in a clearance mode, so that the bearing safety and the service life of the floor supporting seat are effectively protected.

    本发明属于轨道交通车辆设备地板结构领域,公开一种轨道车辆地板支撑座,包括贴合地板的顶面,及安装于地板底架的安装槽内的座体;安装槽由安装底板和对称设置凸出安装底板上的两个卡合部围合而成;所述座体上设置有容置腔体;容置腔体包括与顶面的下端贴合的连接翼及与连接翼连接向内预弯曲的侧面区段,安装后,地板底架的卡合部顶端与连接翼呈间隙设置;间隙的宽度大于支撑座竖直方向的变形量,支撑座竖直方向的变形量为竖直方向的工作载荷与支撑座的线性刚度的比值。本发明通过对支撑座的结构改变,实现了地板支撑座与地板底架的有效安装。将地板底架的卡合部顶端与连接翼呈间隙设置,有效地保护了地板支撑座的承载安全性及使用寿命。
