The invention discloses an integrated door ring and a hot stamping design method of the integrated door ring, relates to the technical field of metal plastic forming, and solves the technical problem that the light weight and the anti-collision level of the integrated door ring need to be improved in the prior art. The integrated door ring comprises a B column reinforcing plate, the B column reinforcing plate comprises a first section, a second section and a third section which are sequentially connected in the longitudinal direction, the first section is connected with the threshold reinforcing plate, the third section is connected with the top frame reinforcing plate, the thickness of the second section is gradually increased in the longitudinal direction, a small-thickness end and a large-thickness end are formed at the two ends in the longitudinal direction respectively, and the small-thickness end is connected with the first section. The thickness of the first section is not larger than that of the small-thickness end, the large-thickness end is connected with the third section, and the thickness of the third section is not smaller than that of the large-thickness end. When the side face of an automobile is collided, the lower portion of the B column is prone to deformation and energy absorption, the head of a passenger is effectively protected, and the light weight level of the integrated door ring is improved.

    本发明公开一体化门环及一体化门环的热冲压设计方法,涉及金属塑性成形技术领域,解决了相关技术中一体化门环的轻量化及抗碰撞水平待提高的技术问题。一体化门环包括B柱加强板,B柱加强板包括在纵向上依次连接的第一段、第二段和第三段,第一段与门槛加强板连接,第三段与顶框加强板连接,第二段在纵向上厚度递增,在纵向两端分别形成小厚度端和大厚度端,小厚度端与第一段连接,第一段的厚度不大于小厚度端的厚度,大厚度端与第三段连接,第三段的厚度不小于大厚度端的厚度。当汽车侧面发生碰撞时B柱靠下部分容易发生变形和进行吸能,有效地保护乘客头部,而且提高了一体化门环的轻量化水平。
