Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile sealing mechanism, and particularly relates to a top sealing structure of a down-type glass lifting back door and a vehicle. BACKGROUND

[0002] The back door of an automobile is a door that can be opened in an emergency at the tail of the automobile. The sealing structure of the back door of the automobile is a structure that must be formed on the back door of the automobile. The sealing structure can effectively prevent airflow or water outside the automobile from entering the interior of the automobile through the connecting gap between the back door and the automobile body, thereby improving the comfort of the automobile.

[0003] In the prior art, for example, a patent document with the authorization announcement number CN203920375U discloses an automobile back door sealing strip. The automobile back door sealing strip comprises a foamed glue part at the upper portion and a mounting clamping seat at the lower portion. An n-shaped framework is arranged in the mounting clamping seat. A C-shaped cape is arranged on the side of the mounting clamping seat towards the interior of the automobile. A flat pull wire is arranged at the side of the mounting clamping seat towards the interior of the automobile and corresponds to the cape. The scheme reduces the scrappage rate and cost of the automobile back door sealing strip under the premise of facilitating assembly. In addition, a patent document with the publication number CN108146207A discloses a back door opening sealing strip. The back door opening sealing strip at least comprises a sealing strip body. A metal framework is arranged in the sealing strip body. The metal framework comprises a plurality of framework units. The framework units are in a U-shaped structure and comprise an inner vertical unit, an outer vertical unit and a groove bottom unit. The two ends of the groove bottom unit are connected with the inner vertical unit and the outer vertical unit, respectively. Adjacent two framework units are connected through a connecting part at the position where the inner vertical unit and the groove bottom unit are connected. A groove hole is arranged at the position corresponding to the connecting part of the framework unit. The back door opening sealing strip has better ductility and bendability. The length of the back door opening sealing strip is relatively stable. The sealing property of the opening of the back door of the automobile is better. The sealing life is longer.

[0004] The back door sealing strips described above are mainly used for sealing the back door and the automobile body. However, the automobile technology in China is increasingly mature. The precision is greatly improved. Various new automobile back door structures are started to be developed. The existing ordinary up-type back door structure is simple.
