Door lower sealing structure

Abstract

The invention relates to the field of automobile parts, in particular to a lower sealing structure for a door. A sealing strip is installed on an automobile door inner plate and comprises a straight-wall-shaped base part, a first lip edge and a second lip edge, wherein the first lip edge and the second lip edge are fixed to the portion below the base part and extend in a suspended mode. The first lip edge corresponds to a lateral surrounding outer plate on a sill in position, when an automobile door is closed, the first lip edge is attached to the lateral surrounding outer plate, the second lip edge is attached to an automobile door decorative plate, the tail end of the lower portion of the automobile door decorative plate extends to the lower portion of the second lip edge, and the base part is provided with a through hole used for being connected with the automobile door inner plate. The lateral surrounding outer plate on the sill is shielded through the first lip edge, so that silt is prevented from directly knocking the lateral surrounding outer plate and prevented from being accumulated on the sill. Through the structure, an installation hole does not need to be formed in the lateral surrounding outer plate on the sill, so that rainwater or dust is effectively prevented from entering an automobile. The second lip edge is attached to the automobile door decorative plate so that the silt can be effectively prevented from being accumulated. When the door is opened, the sealing strip on the lower portion of the door is shielded through the automobile door decorative plate, so that attractiveness of the whole automobile is not affected.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a lower door sealing structure. Background technique [0002] At present, there are generally four structures for the lower door sealing strip. One is that the bubble tube structure is connected to the door decorative panel through buckles and lip snaps. In addition, the decorative panel supplier will supply the assembly afterwards, resulting in high cost of the decorative panel, and the lower part of the door is covered by the decorative panel, and a drainage structure needs to be made on the decorative panel to facilitate drainage. Moreover, the closing force of the door is relatively large, the weight is relatively large, and the appearance effect is poor due to the accumulation of sand and dust on the outer surface; the second is that the lip structure is fixed on the outside of the threshold through the buckle on the sealing strip. The sheet metal in the installation hole area of ...

[0002] At present, there are generally four structures for the lower door sealing strip. One is that the bubble tube structure is connected to the door decorative panel through buckles and lip snaps. In addition, the decorative panel supplier will supply the assembly afterwards, resulting in high cost of the decorative panel, and the lower part of the door is covered by the decorative panel, and a drainage structure needs to be made on the decorative panel to facilitate drainage. Moreover, the closing force of the door is relatively large, the weight is relatively large, and the appearance effect is poor due to the accumulation of sand and dust on the outer surface; the second is that the lip structure is fixed on the outside of the threshold through the buckle on the sealing strip. The sheet metal in the installation hole area of ​​the strip is prone to water ingress, and after the water enters, there is no drainage structure inside the sheet metal, which will cause the sheet metal to rust. After the door is closed, sediment will accumulate on the surface of the sealing strip, and the trouser legs of passengers will scratch the sealing strip after getting off the car. Dirty trouser legs will cause inconvenience for passengers getting on and off the car; the third matching method is similar to the second one. Considering that water enters the sealing strip buckle hole, it is fixed on the door sill by glue. This structure avoids the rust of the sheet metal. risk, but the glue has a risk of falling off
