The invention relates to the technical field of automobile manufacturing, in particular to an automobile A column and top cover beam assembling structure and an automobile with the assembling structure. The A-column tubular beam is an arc-shaped tube, a tubular beam filler is arranged in the tube, the A-column tubular beam is provided with a first variable-diameter part and a second variable-diameter part, a partition plate is fixedly connected to the end, close to the first variable-diameter part, of the A-column tubular beam, and a cavity in an A-column reinforcing plate is sealed through the partition plate; the top cover transverse pipe beam is fixedly installed on the second reducing part of the A column pipe beam through the pipe beam connector, and pipe beam filler is arranged in the top cover transverse pipe beam. The closed cage type structure is formed by the A column tubular beam and the top cover transverse tubular beam, cost is lower, safety and overall rigidity are better, meanwhile, the foaming materials are poured into the closed cage type structure, the strength of the A column can be greatly improved, and higher passive safety guarantee is provided for consumers.
本发明涉及汽车制造技术领域,尤其是涉及一种汽车A柱与顶盖横梁装配结构及具有该装配结构的汽车。包括:A柱管梁呈弧状管,管内设有管梁填充物,具有第一变径部和第二变径部,其中靠近第一变径部的A柱管梁端部固定连接有隔板,利用隔板封闭A柱加强板内的型腔;顶盖横管梁以及管梁接头,顶盖横管梁通过管梁接头固定安装在A柱管梁的第二变径部,其中顶盖横管梁内部设有管梁填充物。本发明通过A柱管梁以及顶盖横管梁形成的封闭笼式结构,成本更低,安全性及整体刚性更好,同时在封闭笼式结构内灌注发泡材料,可大大增加A柱的强度给消费者提供更高的被动安全保障。
