An automobile body structure capable of improving rigidity of a side wall outer plate and an automobile belong to the technical field of automobile parts, and are fixed on a CD column assembly through a rear wheel cavity rubber block, so that flexible connection between the side wall outer plate and the CD column assembly is realized, Y-direction support is provided for the side wall outer plate, static rigidity and dynamic rigidity transfer functions of the side wall outer plate are improved, back row noise of the automobile is reduced by 1.54 dB under a rough road scene of 60km/h, and the automobile is more comfortable to use. And the driving comfort of passengers is improved. And meanwhile, the rear wheel cavity rubber block replaces a traditional reinforcing rubber sheet, and due to the design of increasing and decreasing and the lightweight design of the rubber block, the performance is improved, and meanwhile, the cost and quality increase amplitude is small.
一种提升侧围外板刚度的车身结构及汽车,属于汽车零部件技术领域,通过后轮腔胶块固定在CD柱总成上,实现了侧围外板与CD柱总成的软连接,给予侧围外板Y向支撑,提升了侧围外板静刚度和动刚度传函,汽车在60km/h的粗糙路场景下后排噪音下降1.54dB,提高了乘客的驾乘舒适性。同时后轮腔胶块替代了传统的补强胶片,一增一减的设计和胶块的轻量化设计在提升性能的同时做到了成本和质量增幅较小。
