A column joint angle waterproof structure of frameless vehicle door first sealing strip

Abstract

The invention relates to a frameless car door first sealing strip A column joint angle waterproof structure, and belongs to the technical field of car waterproof structures. The waterproof structure comprises an A column corner drainage structure part and adjacent spliced opponent matching parts, continuous strip-shaped bulges I which protrude out of the surface of the structural part and are usedfor draining water are arranged on the inner side surface of the vehicle of the structural part; continuous strip-shaped bulges II which are connected with the bulges I, protrude out of the surface of the opponent matching piece and are used for draining water are arranged on the opponent matching piece; water flows out of the vehicle through the formed protruding drainage grooves from the outside of the vehicle; the A-pillar joint angle drainage structural parts forms a mutually-embedded structural form for preventing the joint from leaking water at the splicing part of the inner side surface of the vehicle door; therefore, it is guaranteed that all water flow passing through one outer water cutting sealing strip is completely discharged out of the automobile, and it is guaranteed that no water enters an automobile dry area; the technical problems of waterproofness of the A-pillar joint corner of the first sealing strip of the frameless vehicle door and water leakage of the A-pillararea of the frameless vehicle door are solved.

Description

technical field [0001] The invention relates to a frameless car door head seal strip A-pillar joint angle waterproof structure, which belongs to the technical field of waterproof structure of automobile sealing system. Background technique [0002] Frameless door is a very popular design at the end of the 20th century, but now it seems that this design still has a strong charm. It is a fashionable design in the history of automobile development. Frameless windows are generally used on sports cars or sports cars, especially convertible sports cars; because there are no frames, the driver's field of vision will be wider, especially the blind spot near the A-pillar can be reduced.
