Car roof assembly and vehicle

Abstract

The invention provides a car roof assembly and a vehicle. The car roof assembly comprises a steel framework and a top plate assembly. The steel framework comprises a frame and a plurality of longitudinal beams located in the frame and connected with the frame, and the plurality of longitudinal beams are arranged at intervals in the length direction of the vehicle body and extend in the width direction of the vehicle body; and the top plate assembly comprises a first aluminum plate layer, a second aluminum plate layer and a sandwich layer, the sandwich layer is bonded between the first aluminum plate layer and the second aluminum plate layer, and the first aluminum plate layer is bonded with the frame and the longitudinal beams. The frame is made of the steel, and the longitudinal beams made of the steel are arranged in the frame, so that the structure is simple, and the steel framework is high in structural strength and high in safety. By the adoption of the top plate assembly comprising the first aluminum plate layer, the second aluminum plate layer and the sandwich layer, the overall mass of the roof assembly can be reduced favourably, and lightweight design of the roof assembly is facilitated; and the top plate assembly is bonded with the steel framework, so that the operation is simple, the cost is saved, and the roof assembly is small in overall mass and high in strength.

Description

Technical field[0001]The present invention relates to the field of vehicle manufacturing techniques, and more particularly to a roof assembly and a vehicle.Background technique[0002]Track vehicles, such as rail trams, subway, etc. have brought great convenience to people's lives. Among them, the distance between the carriage of the low floor trail is small, and there is no need to set a specific platform. It is very convenient for the passenger's up and down, especially for the elderly, children, pregnant women, disabled people. Large convenience.[0003]The low-floor tram has a small distance from the track, and the bottom plate is limited, so that a part of the electrical equipment, cable, etc. need to be installed on the roof, which requires both the roof to be light, but also has strong bearer. ability. All aluminum alloy roof or all stainless steel roofs are usually used in the prior art.[0004]However, the whole aluminum alloy car is formed by the use of aluminum profiles, not on...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a roof assembly and a vehicle to solve the problem of high production cost and low production efficiency of an all-aluminum alloy roof for low-floor trams in the prior art; low weight and poor safety of an all-stainless steel roof technical problem
