The invention discloses a frameless car door C column sealing structure which comprises a C column metal plate and a rear door quarter window, the C column metal plate and the rear door quarter window are located behind a rear car door, the C column metal plate is connected with a car roof longitudinal beam of a car body, a C column sealing strip is arranged on the front edge of glass of the rear door quarter window, and a sealing strip guide rail is arranged between the C column metal plate and the glass of the rear door quarter window. The C column sealing strip is installed on the sealing strip guide rail, the sealing strip guide rail is fixed to glass of the rear door quarter window, the C column sealing strip is provided with a first lip and a second lip, and when rear door glass on a closed rear door rises, the rear edge of the rear door glass is in extrusion sealing with the first lip, and the inner side of the rear door glass is in extrusion sealing with the second lip. By means of the technical scheme, when the rear car door is closed and the rear door glass is lifted, the first lip and the second lip are matched with the rear door glass to form two seals, the sealing effect is enhanced, the NVH performance is improved, and the waterproof effect of the combination portion of the C column and the car roof longitudinal beam is improved.
Description
technical field [0001] The invention relates to a sealing structure for a vehicle body, more specifically, it relates to a sealing structure for a C-pillar of a frameless vehicle door. Background technique [0002] With the continuous development of the automobile market, the application of frameless doors is gradually increasing. However, the main problems currently existing in frameless doors are complex structures, poor NVH performance, and poor sealing, which often lead to air and rain leakage. The C-pillar of the body corresponds to the rear seats, and the tightness of the C-pillar directly affects the comfort perception of the rear passengers. At present, frameless car doors on the market are mainly based on integral sealing structures, with only one seal, and the entire ring seal is composed of multiple sections. The C-pillar has poor compatibility with the environment, and the number of sealing stages is relatively small, resulting in poor local sealing. , thus affe...
