Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a water-guiding structure for a sealing strip. Background Technology

[0002] Currently, frameless sealing systems are widely used in the automotive industry. They achieve sealing by eliminating traditional door frames and relying on door glass and grooved sealing strips, thereby improving the simplicity of the appearance and aerodynamic performance.

[0003] However, the sealing logic of existing frameless sealing systems is "bubble tube sealing" or "bubble tube sealing + lip water guiding". For frameless hardcore off-road vehicles with a removable roof, the sealing is achieved solely by the cooperation between the bubble tube of the front roof sealing strip and the front roof sheet metal and the removable roof. No independent water guiding structure is designed. On the one hand, the sealing reliability is highly dependent on the manufacturing precision of the whole vehicle. In the harsh environment of heavy rain, rainwater can easily seep in along the mating surface between the bubble tube of the front roof sealing strip and the front roof sheet metal and the removable roof. On the other hand, the infiltrated rainwater lacks a directional flow path and cannot be discharged in time. It is easy to accumulate on the top of the vehicle and enter the passenger compartment, which makes it difficult to meet the high sealing requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-guiding structure for a sealing strip, solving the problems of insufficient sealing reliability and lack of water-guiding capacity in existing frameless sealing systems with detachable top covers.

The side trim strip is located on the A-pillar sheet metal side and is connected to the body structure. The side trim strip guide is located on the side trim strip and receives rainwater guided by the front roof seal strip. The A-pillar guide rail is fixed to the A-pillar sheet metal, and the two ends of the front door groove are respectively engaged with the inner side of the A-pillar guide rail groove and the metal stop edge of the side trim strip. The front door trim is equipped with a drainage channel and a front door trim A-pillar bubble pipe. The side trim guide pipe is connected to the drainage channel, and the drainage channel and the front door trim A-pillar bubble pipe are connected to form a water guiding path.

[0006] Preferably, the front door drainage groove is provided with a U-shaped plastic insert.
