Abstract

The invention relates to a top cover cross beam structure assembly and a vehicle, the top cover cross beam structure assembly comprises a top cover cross beam, and the top cover cross beam is of a high pressure cast aluminum structure; the top cover cross beam comprises a body and a reinforcing rib accommodating space arranged on the body; a positioning hole is formed in the body, and the positioning hole is used for fixing the top cover cross beam on a vehicle body; the reinforcing rib containing space comprises a plurality of reinforcing ribs, and a plurality of component mounting holes are formed in the reinforcing ribs. Through the structural layout of the top cover cross beam structure assembly and the design of the double-row connecting ends on the side of the vehicle body, the top cover cross beam integrating portability, integration, high tolerance and safety is achieved, and meanwhile the manufacturing cost of the top cover cross beam is reduced.

Description

technical field [0001] The invention relates to the technical field of roof beams and automobile body structures, in particular to a roof beam structure assembly and a vehicle. Background technique [0002] With the progress of the times, the requirements for lightweight vehicles are getting higher and higher; body lightweight technology is an important part of vehicle lightweight; more and more lightweight materials and processes are used on the body, of which aluminum alloy Among various aluminum alloy process methods, vacuum high-pressure die-casting can provide high strength, high part precision, good welding / riveting performance, and can integrate two or more parts at a specific position. Play a very good weight loss and cost reduction. [0003] At present, the front and rear beams of the traditional roof are generally connected by welding the upper and lower sheet metal to form a cavity. The traditional structural steel body needs measures such as increasing material ...
