The invention discloses a C-column structure, a side coaming assembly and a vehicle with the same, the C-column structure comprises the C-column structure, the front side contour of the C-column structure is a front contour line, the front contour line extends in a curve shape in the vertical direction, the front contour line comprises multiple front contour line segments which are sequentially connected from top to bottom, and the front contour line segments are connected with the C-column structure; one of the two adjacent front contour line segments protrudes forwards, the other one of the two adjacent front contour line segments sinks backwards, the height-width ratios of the two adjacent front contour line segments are different, the rise of the front contour line segment is d, the chord length of the front contour line segment is L, and the height-width ratio is the ratio of d to L. The C-column structure comprises a C-column outer plate; the C-column inner plate is arranged on the inner side of the C-column outer plate, a turnover covered edge is formed at the front end of the C-column inner plate, and the turnover covered edge wraps the front edge of the C-column outer plate and covers the outer side face of the C-column outer plate. According to the C-column structure, vibration energy can be effectively attenuated, meanwhile, the structural strength can be improved, and the impact resistance and deformation resistance of the C-column structure are improved.

    本发明公开了一种C柱结构、侧围板组件和具有其的车辆,所述C柱结构,包括:C柱结构,C柱结构的前侧轮廓为前轮廓线,前轮廓线在上下方向上呈曲线延伸,前轮廓线包括由上至下依次连接的多段前轮廓线段,相邻两个前轮廓线段中的一个朝向前凸出且另一个朝向后凹陷,相邻两段前轮廓线段的高宽比不同,前轮廓线段的矢高为d,前轮廓线段的弦长为L,高宽比为d与L的比值,C柱结构包括:C柱外板;C柱内板,C柱内板设在C柱外板的内侧,C柱内板的前端部形成有翻折包边,翻折包边包住C柱外板的前边沿且覆盖在C柱外板的外侧面。根据本发明的C柱结构,可以有效衰减振动能量,同时也可以提高结构强度,改善C柱结构的抗冲击抗变形能力。
