The invention relates to the technical field of frameless door automobiles, and particularly discloses a drainage structure for an automobile column B. The drainage structure comprises an automobile column B body, the automobile column B body sequentially comprises a column B upper connecting corner, a column B extrusion section and a column B waist line connecting corner from top to bottom, and the column B upper connecting corner is used for being connected with a sealing strip and used in cooperation with frameless door glass; a water accumulation area is arranged between the B column upper connecting corner and the sealing strip and is a gradually-changed slope, the highest height point of the slope is close to the frameless door glass and the B column waistline connecting corner, the bottom of the B column waistline connecting corner is an arc-shaped section, the arc-shaped section is flush with an automobile waistline, and a drainage hole is formed in the lowest point of the water accumulation area. The drainage hole penetrates through the B-column upper connecting corner, the B-column extrusion section and the B-column waistline connecting corner, the drainage hole located in the B-column waistline connecting corner extends to the position close to the automobile B-column body and the bottom of the sheet metal part in the direction of the arc-shaped section, and the problem of drainage accumulation in a traditional frameless automobile door frame sealing strip B-column upper connecting corner area is solved.

    本发明涉及无框车门汽车技术领域,具体公开了一种用于汽车B柱的排水结构,包括汽车B柱本体,所述汽车B柱本体从上往下依次包括B柱上接角、B柱挤出段和B柱腰线接角,B柱上接角:用于连接密封条和配合无框门玻璃使用,在所述B柱上接角与密封条之间设有积水区,积水区为渐变式斜面,斜面高度最高点靠近无框门玻璃,B柱腰线接角:B柱腰线接角的底部为弧形段,所述弧形段与汽车腰线平齐,在积水区的最低点设有排水孔,所述排水孔贯穿B柱上接角、B柱挤出段和B柱腰线接角,位于B柱腰线接角内部的排水孔沿着弧形段方向延伸到靠近汽车B柱本体与钣金件的底部,解决了传统的无框车门门框密封条B柱上部接角区域排水堆积问题。
