The invention relates to the technical field of automobile part assembly, in particular to a platform automobile dashboard cross beam structure and an assembly method.The platform automobile dashboard cross beam structure comprises a thick tubular beam and a thin tubular beam, a left end plate sub-assembly is fixedly installed at one end of the thick tubular beam, and a right end plate sub-assembly is fixedly installed at one end of the thin tubular beam; a thick and thin tubular beam connecting piece is arranged between the thick tubular beam and the thin tubular beam, a left middle supporting sub-assembly is fixedly installed at the bottom of the thick and thin tubular beam connecting piece, a right middle supporting sub-assembly is fixedly installed at the bottom of the thin tubular beam, and a middle channel connecting support is fixedly installed between the right middle supporting sub-assembly and the left middle supporting sub-assembly. A thick tubular beam and a thin tubular beam are welded through a thick and thin tubular beam connecting piece to form a cross beam body supporting structure, the two ends of the cross beam body supporting structure are welded through a left end plate sub-assembly and a right end plate sub-assembly to achieve installation with a body in white, the two sides of the thick and thin tubular beam connecting piece are in flanging lap joint, and the situation that a butt joint scheme between tubular beams is difficult to match is avoided; and stress is easy to concentrate.

    本发明涉及汽车零部件装配技术领域,具体涉及一种平台化汽车仪表板横梁结构及装配方法,包括粗管梁和细管梁,所述粗管梁的一端固定安装有左端板分总成,细管梁的一端固定安装有右端板分总成,所述粗管梁与细管梁之间设置有粗细管梁连接件,所述粗细管梁连接件的底部固定安装有左中支撑分总成,所述细管梁的底部固定安装有右中支撑分总成,所述右中支撑分总成与左中支撑分总成之间固定安装有中通道连接支架。利用粗管梁与细管梁通过粗细管梁连接件焊接形成横梁主体支撑结构,横梁主体支撑结构两端通过左端板分总成与右端板分总成焊接实现与白车身的安装,粗细管梁连接件两侧翻边搭接,避免管梁之间对接方案匹配困难,应力易集中问题。
