The invention relates to a sliding door upper sealing strip in an automobile and a mounting structure thereof. The sliding door upper sealing strip in the automobile comprises a base body which is ina long strip shape and is used for being connected with an automobile door frame, a bubble pipe which protrudes out of the base body upwards and is used for elastically making contact with an automobile door inner plate, a first lip edge connected with the base body and used for elastically making contact with the automobile door frame, a second lip edge connected with the base body and used for elastically making contact with the automobile door inner plate, and a third lip edge connected with the base body and used for shielding the inner edge of the automobile door frame. The first lip edgeis closer to the outer side of an automobile door seam compared with the bubble pipe, a drainage groove opened to the outer side of the automobile door seam is defined by the first lip edge and the bubble pipe, the second lip edge is closer to the inner side of the automobile door seam compared with the bubble pipe, and the third lip edge is closer to the inner side of the automobile door seam compared with the bubble pipe. The defects on the inner edge of the door frame are shielded while the sealing performance of the sliding door upper sealing strip in the automobile is improved.
Description
