They are closely attached to the vehicle body to form a complete sealing system. The roof sealing strip is generally made of rubber or plastic material. Because the roof sealing strip has the functions of waterproofing, windproofing, shock absorption, dustproofing and sound insulation, it is widely used in the field of automobiles. When the roof sealing strip is used with the automobile, the traditional roof sealing strip does not have a buffer mechanism inside to protect the roof sealing strip from being squeezed and cracked after long-term use, which reduces the service life of the roof sealing strip.

[0003] In order to overcome the above-mentioned defects, the sealing strip for the automobile sunroof in the prior art 1 (Chinese patent with application number CN201810257778.9 and application date of 2018-03-27) has reliable connection between the sealing strip and the sunroof, a drainage groove and a drainage port are provided to facilitate direct drainage of accumulated water and prevent the accumulated water from affecting the components. The cavity and the buffer step are used to reduce the impact force and reduce the adverse effects of vibration on the sunroof. The sealing strip body is fixed to the roof panel through multiple contacts to enhance the sealing performance. Although the prior art can protect the roof sealing strip from being squeezed and cracked after long-term use, it does not have an exhaust mechanism to exhaust and ventilate the roof sealing strip when it is used with the automobile, which can cause unstable air pressure inside the roof sealing strip and poor drainage performance of the roof sealing strip, reducing the service performance of the roof sealing strip and the practicability.
