The invention discloses a B column body structure, a B column and an automobile, the B column body structure comprises an upper column section, a lower column section, a reinforcing structure and an energy absorption structure, the lower column section is connected to the lower end of the upper column section, the reinforcing structure is arranged on the upper column section, and the energy absorption structure is arranged on the lower column section and used for deforming and absorbing energy when the B column is impacted, the thickness of the upper column section is larger than that of the lower column section, and the tensile strength of the upper column section is larger than that of the lower column section. According to the scheme, the B column body structure is divided into the upper section and the lower section, the thickness and the tensile strength of the upper column section are both larger than those of the lower column section, the reinforcing structure is arranged on the upper column section, the energy absorption structure is arranged on the lower column section, and therefore the whole structure is strong in the upper portion and weak in the lower portion, a B column reinforcing plate can be omitted, and a double-layer structure is replaced by a single-layer structure; the invention provides a B column body structure which is light in weight and low in cost while the safety performance is met.
本发明公开一种B柱本体结构、B柱以及汽车,其中,B柱本体结构包括上柱段、下柱段、加强结构和吸能结构,所述下柱段连接于所述上柱段的下端,所述加强结构设于所述上柱段,所述吸能结构设于所述下柱段,用以在所述B柱被撞击时变形吸能,其中,所述上柱段的厚度大于所述下柱段的厚度,且所述上柱段的抗拉强度大于所述下柱段的抗拉强度。本方案通过将B柱本体结构分为上下两段,使上柱段的厚度和抗拉强度均大于下柱段,且在上柱段设置加强结构和下柱段设置吸能结构,以实现整体结构上强下弱,如此,可以取消B柱补强板,以单层结构代替双层结构,提供了一种在满足安全性能的同时能够实现轻量低成本的B柱本体结构。
