The invention discloses an end door cross beam and a railway vehicle end door comprising the end door cross beam, and relates to the technical field of end doors for railway vehicles, the end door cross beam comprises a branch cross beam which is connected to a door stand column and extends to an end corner column, and one end, inserted into a sliding slot in the end corner column, of the branch cross beam is provided with a pressure sensing switch; the outer sides of the branch cross beams are slidably sleeved with sliding sleeve plates blocked by the limiting sliding blocks, electromagnets for pulling the limiting sliding blocks to retract into the branch cross beams are arranged in the branch cross beams, and reinforcing connecting plates are fixedly connected between the adjacent branch cross beams. The door stand columns and the end corner columns are fixed through the supporting cross beams and the fixing baffles, when the end corner columns bear large impact force, the door stand columns and the end corner columns are separated from fixation, the impact force is absorbed through elastic deformation of the elastic connecting blocks, and therefore the door stand columns and the end corner columns can be firmly fixed. The problem that the door cannot be opened due to bending deformation of the door stand column under overlarge impact force is solved.
本发明公开了一种端门横梁及含有其的轨道车辆端门,涉及轨道车辆用端门技术领域,包括连接在门立柱上并伸向端角柱的支横梁,且支横梁插入端角柱中滑动插槽的一端带有压力传感开关,且压力传感开关与滑动插槽中的固定挡板连接,所述支横梁外侧滑动套设有被限位滑块挡住的滑动套板,且支横梁内设置有拉动限位滑块收回至支横梁内的电磁铁,相邻的所述支横梁间固定连接有加固连板,且加固连板和滑动套板间固定连接有弹性连块,本发明通过支横梁和固定挡板对门立柱和端角柱进行固定,并在端角柱承受较大撞击力时使得门立柱和端角柱脱离固定,利用弹性连块的弹性形变吸收撞击力,避免门立柱在过大撞击力下弯曲变形使得门无法打开的问题。
