The invention relates to the technical field of rail transit equipment, in particular to a skin force-bearing type vehicle body shoulder structure, a vehicle roof structure comprises a top frame, a plurality of first longitudinal beams and a plurality of second longitudinal beams, a top plate covering the top frame; the side wall structure comprises a side frame which comprises a plurality of side beams and at least one second longitudinal beam; the edge of the side plate extends towards the top of the vehicle body relative to the second longitudinal beam, and the extending part is fixedly connected with the first longitudinal beam located on the edge of the top frame. A sealed space is formed between the extension part and the top plate. The original mode that main force bearing is conducted through a beam body is changed, the original continuous ring beam is discontinued into the cross beams and the side beams, the discontinued parts are connected through the extending parts of the side plates, and therefore the shoulder structure mainly bearing force through the side plates is formed, the arrangement density of the cross beams and the side beams is effectively reduced through the mode, and the bearing capacity of the cross beams and the side beams is improved. The change of the stress mode can also reduce the use amount of the two materials, so that the production cost and the production difficulty are effectively reduced.

    本发明涉及轨道交通设备技术领域,尤其涉及一种蒙皮承力型车体肩部结构,车顶结构包括:顶部框架,包括若干横梁和至少两个第一纵梁;顶板,覆盖顶部框架;侧墙结构包括:侧框架,包括若干侧梁和至少一个第二纵梁;侧板边缘相对于第二纵梁向车体顶部延伸,且延伸部分与位于顶部框架边缘的第一纵梁固定连接;延伸部分与顶板间形成密封空间。本发明中改变了原本通过梁体进行主要承力的方式,使得原本连续的环梁被间断为横梁和侧梁,且间断的部分通过侧板的延伸部分来实现连接,从而形成了以侧板承力为主的肩部结构,通过上述方式使得横梁和侧梁的设置密度有效降低,受力方式的改变同样可降低二者材料的用量,从而使得生产成本及生产难度有效降低。
