The invention discloses a drain pipe structure for an automobile air conditioner. The drain pipe structure for the automobile air conditioner comprises a drain pipe (1), a sheet metal hole (31) and a pier head (2), wherein the sheet metal hole (31) is formed in a sheet metal (3); the pier head (2) is arranged at the end part of the drain pipe (1); the diameter of the pier head (2) is larger than that of the drain pipe (1); a mounting hole in which the drain pipe (1) is mounted is formed in the pier head (2); and the pier head (2) is adaptive to the sheet metal hole (31). A bending part extending inwards is arranged around the sheet metal hole (31); and through the bending part, the sheet metal hole (31) is formed with a depth. As the matching length of the drain pipe (1) in the sheet metal (3) is increased, the NVH (Noise Vibration and Harshness) sealing effect is especially good. And moreover, after a matching structure is lengthened, the corresponding stability and structural performance are also stable.
