The corner structure of the lower sealing strip of the automobile door and the lower sealing structure of the automobile door

Abstract

The invention provides a connecting angle structure for a vehicle door lower part sealing strip and a vehicle door lower part sealing structure. The connecting angle structure comprises a straight wall shaped base and a first lip, a second lip and a third lip which are connected with the base, wherein the first lip is connected with the outer side surface of the base, the second lip is connected with the side end of the base, the third lip is connected with the top end of the base, and the third lip, the second lip and the base are interconnected in a circle to form the connecting angle structure. The connecting angle structure of the vehicle door lower part sealing strip is arranged at the end part of a vehicle door innovatively, the base extends by virtue of the cross section of the main body of the sealing strip so as to effectively prevent silt from beating a side metal plate in the running process of a vehicle, a gap between the vehicle door and the sealing strip is sealed by overlapping and pressing the lips on two sides, and the side surface is fixed onto a decorative plate of the vehicle door through a buckle, thereby obstructing silt from entering a cavity between the decorative plate and the internal plate of the door in all directions.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a lower sealing structure of an automobile door, in particular to a lower sealing strip corner structure of an automobile door and a lower sealing structure of an automobile door having the corner junction structure. Background technique [0002] With the rapid development of the automobile industry, human beings have higher and higher requirements for the convenience and appearance of vehicles. The lower part of the door is installed under the door of the car, which mainly plays the role of preventing the entry of mud and sand and covering the sheet metal. At present, most of the lower sealing strips of automobile doors adopt a lip structure and are fixed to the inner panel of the door through buckles, and the bottom of the sealing strip is overlapped with the decorative panel of the door. This structure can effectively prevent the sand from directly hitting the outer panel of the side...

AI Technical Summary

Problems solved by technology

But the main disadvantage of the existing structure of this type of weather strip is that the installation surface of the weather strip is limited by the structure of the inner panel of the car door and cannot extend to the boundaries at both ends of the car door, so that different degrees of sheet metal will appear at the two ends of the car door. The leakage of gold is very unsightly. At the same time, the cavity between the lower sealing strip and the decorative panel is completely exposed at both ends of the door, which is easy to form the accumulation of mud and sand, and mud and sand will also adhere to the body sheet metal in some places. It is inconvenient for passengers to get on and off the door, so it is urgent to innovate and improve the structure of the existing door lower sealing strip
