The invention provides a vehicle body structure, which comprises: a roof, a side wall, an underframe and an end wall, and the roof, the side wall and the end wall are welded by laser welding The roof includes a roof frame, a roof, a corrugated roof, and an end plate; the roof frame includes two side beams extending along the length of the vehicle body and a plurality of side beams spanning the two side beams. As for the curved beam, the top plate and the corrugated top plate are sequentially arranged on the roof frame at intervals, the end plate is located at the end of the side beam, and at least one air-conditioning platform is arranged on the top plate; the side wall and the The end walls are all connected to the underframe, and the upper parts of the end walls and the side walls are connected to the roof. Realized the lightweight and high strength of the train.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a car body structure. Background technique [0002] The stainless steel car body has the characteristics of light weight, corrosion resistance, high temperature resistance, high safety and long life cycle. It can realize non-painting process, meet environmental protection requirements and reduce operation and maintenance costs. At present, light weight and high strength are the basic principles and development trends that should be followed in the design of stainless steel car bodies. [0003] In the prior art, the design of the stainless steel car body mostly adopts arc welding and resistance welding without painting structure; the roof setting is divided into two parts: flat roof and arc roof. One cold-formed steel side beam and several stretch-bent roof curved beams are spot-welded together through connecting plates to form a skeleton structure, and then corrugated plat...
