The fuel tank assembly comprises a tank body and a partition plate, the tank body is provided with a containing cavity used for containing fuel oil, an oil inlet is formed in the top of the tank body, an oil outlet is formed in the bottom of the tank body, the partition plate extends in the vertical direction and is arranged in the containing cavity, and the peripheral side of the partition plate abuts against the side wall of the containing cavity; positioning grooves are formed in the side portions of the partition plates, the partition plates divide the containing cavity into a plurality of cavities, oil through holes are formed in the partition plates in a penetrating mode so that the cavities can be communicated, convex ribs are formed on the side walls towards the partition plates and matched with the positioning grooves so that the partition plates can be fixed, and punched holes are formed in the positions, at the convex ribs, of the box body and used for welding the partition plates and the box body from the outside. According to the technical scheme, the problems of all-welding stress tearing and pure ribbing partition falling are solved by combining the convex ribs with external local welding, the reliability is good, the cost is reduced, and the method is friendly to the working environment of constructors.

    本发明公开一种燃油箱总成和汽车,其中,燃油箱总成包括箱体和隔板,箱体具有用于容纳燃油的容纳腔,箱体顶部开设有进油口,箱体底部开设有出油口,隔板沿上下向延伸,隔板设于容纳腔且周侧抵接容纳腔的侧壁,隔板的侧部设有定位凹槽,隔板将容纳腔分隔成多个腔体,隔板贯设有通油孔,以连通各腔体,侧壁朝向隔板形成有凸筋,凸筋与定位凹槽配合以固定隔板,箱体在凸筋处设有冲孔,用于从外部焊接隔板与箱体。本发明技术方案通过凸筋结合外部局部焊接解决了全焊焊接应力撕裂及单纯的压筋隔板脱落问题,可靠性好,降低成本,对施工人员的工作环境友好。
