Automobile body structure for improving rigidity of side wall outer plate and automobile

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
