Automobile back door running water structure

Abstract

The invention relates to an automobile back door running water structure which comprises a back door frame defining an automobile back door opening, a back door seam allowance edge surrounding the automobile back door opening is arranged on the back door frame, and a back door sealing strip is installed on the back door seam allowance edge. The back door seam allowance edge comprises a lower seamallowance edge body arranged on the lower frame body of the back door frame, the left portion and the right portion of the lower seam allowance edge body are each provided with a water blocking rib protruding towards the outside of a vehicle, the left portion and the right portion of the lower frame body are each provided with a first drainage rib concaved towards the inside of the vehicle, and one end of each of the two first drainage ribs is arranged on the lower seam allowance edge. The other end of each of the two first drainage ribs extends to the area outside the lower seam allowance edge section, and the two first drainage ribs are located on the upstream portions of the two water blocking ribs respectively. The possibility that water enters the back door sealing strip can be reduced, the water in the back door sealing strip can be discharged more thoroughly, and the possibility that the water permeates into the vehicle is reduced; by arranging the first sinking table to be in lap joint with the side wall outer plate, smooth and attractive appearance can be guaranteed.

Description

technical field [0001] The invention relates to auto parts, in particular to an automobile back door flowing water structure. Background technique [0002] The main function of the water flow structure of the back door of the car is to guide the water flow out of the car through the water tank, to prevent the water from seeping into the inside of the car body, to ensure a comfortable environment inside the car and to avoid premature rusting of the body sheet metal in contact with rainwater; when the back door is in the open state , the sink area is visible, and it is required to have a certain aesthetic appearance. Common car back door flow structure such as figure 1 with figure 2 As shown, it includes the back door frame surrounded by the original top cover outer panel 5, two original water tanks 3, two original tail light mounting brackets 2 and the original tail skirt plate 1, and the upper ends of the two original water tanks 3 are respectively connected to the origin...

AI Technical Summary

Problems solved by technology

There are following problems in the above-mentioned automobile back door flowing water structure: figure 2 As shown, the original running water tank 3 and the original side wall outer panel 6 are overlapped by lapping and flanging 8. Due to the complex characteristics of the overlapping area, there is a sudden change in the material thickness of the overlapping surface, so it is necessary to increase the running water tank decoration 4 to cover Improve the appearance quality and increase the manufacturing cost of the whole vehicle; the water in the original water tank 3 easily enters the original back door sealing strip 7, and the water in the original back door sealing strip 7 tends to gather at the lower part of the original back door sealing strip 7, resulting in Water easily seeps into the car
