The invention discloses a main tube structure of an automobile instrument board tubular beam assembly, which comprises a plurality of tube bodies made of aluminum alloy materials and different in diameter, the tube bodies are coaxially arranged, the tube bodies are sequentially connected and fixed end to end according to the diameter to form a main tube structure, and a tube body overlapping areais arranged at the joint of every two adjacent tube bodies. According to the main tube structure of the automobile instrument board tubular beam assembly, the weight of the tubular beam is reduced, the lightweight design of the tubular beam is achieved. In addition, the connecting strength of the tube body is high, so that the structural strength of the whole main tube structure is improved, the whole structure is simple, the manufacturing cost is reduced, and the practicability is high.

    本发明公开了一种汽车仪表板管梁总成主管结构,包括多根直径不同的铝合金材质的管体,多根管体同轴设置,且多根管体按直径依次头尾相连固定并形成主管结构,相邻的两根管体之间的连接处具有管体重叠区。所述汽车仪表板管梁总成主管结构降低了管梁的重量,实现管梁的轻量化设计,另外,管体的连接强度高,因而提高了整体主管结构的结构强度,而且整体结构简单,降低了制作成本,实用性高。
