The invention discloses a welded aluminum honeycomb vehicle body structure, which is characterized in that wall plates, a floor and a top plate for forming the vehicle body structure are all formed by welding welded aluminum honeycomb plates, and the wall plates, the floor and the top plate are fixed through frameworks; the welded aluminum honeycomb plate comprises an upper skin, a lower skin and a welded aluminum honeycomb core, and the welded aluminum honeycomb core is connected between the upper skin and the lower skin through high-temperature brazing. According to the welded aluminum honeycomb vehicle body structure, the welded aluminum honeycomb plate is applied to the vehicle body structure, transmission of sound and heat can be well isolated, the laying amount of sound insulation and heat insulation materials in a vehicle is reduced, secondly, compared with an adhesive honeycomb, the welded aluminum honeycomb plate is not limited to mechanical connection any more and can be connected with the vehicle body in a welded mode, and the service life of the vehicle body is prolonged. And finally, the surface density of the welded aluminum honeycomb panel is lower than that of an aluminum alloy profile, the strength of the welded aluminum honeycomb panel is equivalent to that of the aluminum alloy profile, and further light weight of the rail transit vehicle body can be achieved through application of the welded aluminum honeycomb panel.

    本发明公开了一种焊接铝蜂窝车体结构,用于组成车体结构的墙板、地板和顶板均由焊接铝蜂窝板组焊而成,所述墙板、地板和顶板间通过骨架相固定;所述焊接铝蜂窝板包括上蒙皮、下蒙皮和焊接铝蜂窝芯,其中,焊接铝蜂窝芯通过高温钎焊连接于上蒙皮和下蒙皮之间。该焊接铝蜂窝车体结构,将焊接铝蜂窝板应用于车体结构中,能够较好的隔绝声音、热量的传递,以减少车内隔音隔热材料的铺设量,其次,相较于胶粘蜂窝,焊接铝蜂窝板不再仅限于机械连接,可通过焊接的方式与车体连接,以减少铆接件的大量使用,最后,焊接铝蜂窝板的面密度低于铝合金型材,且其强度与铝合金型材相当,通过焊接铝蜂窝板的应用可实现轨道交通车体进一步的轻量化。
