The invention discloses a B-pillar structure, a differential thickness plate, an integrated door ring and an automobile, the B-pillar structure comprises a TRB differential thickness plate, the TRB differential thickness plate is divided into an interval A, an interval B, an interval C, an interval D, an interval E and an interval F in the length direction, and the thicknesses of plates in all the intervals are the same; with the center line of the interval D as the symmetry axis, the interval C and the interval E are the same in length, and the interval B and the interval F are the same in length; the plate thickness of each interval is a fixed value; a plate unequal-thickness transition area is arranged between every two adjacent intervals, and the length value of each plate unequal-thickness transition area is 90-110 times of the material thickness difference between the corresponding two adjacent intervals; the invention aims to realize obvious weight reduction and cost reduction while the vehicle body meets the safety strength; the door ring B column adopts the TRB differential thickness plate, the thickness change is flexible, the thickness requirements of the door ring at different positions of the B column can be accurately met, structural parts are saved to the maximum extent, and the obvious weight and cost reduction effect is achieved.

    本发明公开了一种B柱结构、差厚板、一体式门环及汽车,包括TRB差厚板,该TRB差厚板在长度方向划分为区间A、区间B、区间C、区间D、区间E和区间F六个区间,每个区间内的板材厚度相同;以区间D的中心线为对称轴,区间C和区间E的长度相同,区间B和区间F的长度相同;每个区间的板材厚度为定值;两两相邻区间之间均设置有板材不等厚过渡区,每个板材不等厚过渡区的长度值为对应相邻的两区间之间90倍‑110倍的料厚差;本发明旨在使车身在满足安全强度的同时,实现显著的减重降本;门环B柱采用TRB差厚板,厚度变化灵活,能够精确满足门环在B柱不同位置上的厚度要求,极大限度地节省结构件,实现显著的减重降本效果。
