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.
