The invention belongs to the technical field of body in white, and provides a cabin roof side rail assembly structure which comprises a front wheel cover upper stiffening beam outer plate, a front wheel cover front connecting plate and a water tank vertical plate, the front wheel cover upper stiffening beam outer plate, the front wheel cover front connecting plate and the water tank vertical plate form an annular closed structure, and a plurality of support assemblies are installed on the surface of the annular closed structure. The invention provides a non-load-bearing automobile cabin roof side rail structure of an internal high-pressure forming process to solve the problems that a traditional automobile headlamp is insufficient in installation rigidity and difficult to stamp and form. Meanwhile, according to the cabin roof side rail structure, the welding number and the welding cost can be reduced, the structural strength, the structural durability and the collision safety performance of the front portion of a vehicle body are effectively improved, and therefore the purposes of being simple in structure, light in weight, low in cost and the like are achieved.

    本发明属于白车身技术领域,提供了一种机舱上边梁总成结构,包括前轮罩上加强梁外板、前轮罩前连接板和水箱竖板,其中前轮罩上加强梁外板、前轮罩前连接板和水箱竖板形成环形封闭结构,该环形封闭结构表面安装有若干种支架总成。本发明提出了内高压成形工艺的非承载汽车机舱上边梁结构,以解决传统汽车大灯安装刚度不足,冲压成形困难的问题;同时,本发明提供的机舱上边梁结构可以减少焊接数量和减少焊接成本,并有效的提升车身前部的结构强度、结构耐久性能和碰撞安全性能,从而为达到结构简单、轻量化、成本低等目的。
