The invention discloses an automobile B column capable of avoiding failure and fracture under the side collision working condition and an automobile comprising the B column, and relates to the field of automobile manufacturing, the automobile B column comprises a B column upper outer plate and a B column lower outer plate, and the B column upper outer plate is made of a high-strength thermal forming material; the B column lower outer plate is made of a high-elongation thermal forming material, the B column lower outer plate is located below the B column upper outer plate, the B column upper outer plate and the B column lower outer plate are seamlessly spliced, a plurality of induction grooves are formed in the B column lower outer plate, the induction grooves are sequentially distributed in the B column lower outer plate from top to bottom, and the induction grooves are formed in the B column lower outer plate from top to bottom. The ratio of the height of the column B upper outer plate to the height of the column B lower outer plate is a preset ratio. The problems that the passenger space invasion amount cannot be guaranteed and the B column cannot be effectively prevented from losing efficacy and being fractured when the B column with the narrow section and the deep type is in the side collision working condition can be effectively solved.
本发明公开了一种避免侧碰工况下失效断裂的汽车B柱及含有该B柱的汽车,涉及汽车制造领域,该汽车B柱包括B柱上外板和B柱下外板,所述B柱上外板的材料为高强度热成型材料;所述B柱下外板材料为高延伸率热成型材料,所述B柱下外板位于所述B柱上外板下方,且所述B柱上外板与B柱下外板间无缝拼接,所述B柱下外板上设有多个诱导槽,且多个诱导槽在所述B柱下外板上由上至下依次分布,所述B柱上外板高度和B柱下外板高度间的比例为预设比例。本发明能够有效解决截面窄且深类型的B柱在侧碰工况中不能达到保证乘员空间入侵量和有效防止B柱失效断裂的问题。
