Split doors are divided into upper and lower parts with the window sill line as the boundary. The upper part is the door window frame, and the lower part is composed of the door inner panel, outer panel and reinforcement. After the split door window frame and the door inner panel are overlapped, a sealing strip will be used along the outer edge of the door. After the door and the door frame are matched, the sealing strip mainly plays the role of preventing wind, water, etc. from entering the car from outside.
[0003] The overlapping part of the door window frame and the door inner panel has a complex structure with a U-shaped corner bend. The window frame trim is sealed with a first sealing strip. The sealing method between the first sealing strip and the window frame trim is mainly adhesive, which has poor durability. Utility Model Content

The expansion structure strip is located at the end of the clamping plate. Limiting plates are arranged on both sides of the expansion structure strip, and the limiting plates abut against the inner wall of the clamping structure of the sealing strip at the overlapping position.
[0008] As a preferred solution of the utility model, the abutment plate is located on the outer wall below the tight strip below the clamping plate, and the abutment plate matches and abuts against the clamping structure of the sealing strip at the overlapping portion.
[0009] As a preferred solution of the utility model, a water guide groove is integrally formed between the top of the tight strip and the clamping plate.
[0010] As a preferred solution of the utility model, the sound insulation component includes sound insulation cotton, and the sound insulation cotton is filled inside the tight strip, and the diameter of the sound insulation cotton is smaller than the diameter of the through hole inside the tight strip.
[0011] As a preferred solution of the utility model, the connection mode of the expansion structure strip and the sealing strip of the overlapping part is plug-in type.
