Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a sealing assembly for the front door triangle area of ​​an automobile. Background Technology

[0002] In the automotive manufacturing industry, the sealing performance of car doors has always been a key factor in measuring vehicle quality. The design and application of sealing components in the front door triangle area, as a crucial part of the door structure, are particularly vital. The sealing components in this area not only affect the vehicle's sealing performance, sound insulation, and dust and water resistance, but also directly impact the comfort of passengers and the overall aesthetics of the vehicle. Traditional front door triangle area sealing designs typically employ a simple combination of sealing strips and trim panels. However, this design has several limitations. Firstly, the connection between the sealing strip and the door trim panel is often not tight enough, easily creating gaps that allow dust and rainwater to enter the vehicle, while also allowing outside noise to penetrate, affecting the quietness of the interior environment. Secondly, due to frequent door opening and closing and vibrations during vehicle operation, the sealing strip is prone to displacement, deformation, or even detachment, further reducing sealing performance. For example, Chinese utility model patent CN205971137U discloses an installation structure for a front triangular window trim piece, including a front triangular window trim piece, a fender, and a side panel. The upper edge of the front triangular window trim piece has a groove extending to the corner of the upper edge. The rear of the front triangular window trim piece has two waterproof clips, which are respectively connected to two mounting holes on the side panel to achieve positioning in the X, Y, and Z directions. In the aforementioned technical solution, the trim piece fits tightly with the sealing strip, achieving a sealing function through the elastic deformation of the sealing strip, thus improving the sealing performance to a certain extent. The trim piece is connected to the mounting holes on the side panel through waterproof clips. While this exposed installation structure can fix the trim piece, it affects the aesthetics of the vehicle's appearance and is prone to scratching the trim piece or door surface during door opening and closing. Furthermore, the fit between the trim piece and the door requires high assembly precision; errors during assembly may lead to poor fit between the trim piece and the door, affecting the sealing effect. Therefore, there is still a need for a structure that can quickly and reliably assemble the sealing strip and trim panel in the front door triangle area of ​​a car. Utility Model Content

[0003] The technical problem to be solved by this application is to provide a sealing component for the front door triangle area of ​​an automobile. The design of the first opening on the sealing strip simplifies the installation process of the trim panel, and the setting of the movable bolt facilitates the disassembly and replacement of the trim panel, reducing assembly steps and the number of parts, and reducing assembly errors in the production process.

[0004] The technical solution adopted in this application is: a sealing assembly for the front door triangle area of ​​an automobile, including a sealing strip and a decorative panel. The sealing strip is provided with a molding area for installing the decorative panel. The molding area is provided with a first opening adapted to the decorative panel. The decorative panel passes through the first opening to be installed into the molding area. A bolt is movably installed on the decorative panel, and one end of the bolt extends through the molding area.

[0005] Compared with existing technologies, the advantages of this application are as follows: by installing the decorative panel within the molding area of ​​the sealing strip, the elastic deformation of the sealing strip allows for a tighter fit between the decorative panel and the door sheet metal, glass, and other components, effectively reducing gaps and improving the sealing effect. The integrated design reduces assembly errors between components, improves assembly precision and stability, and ensures consistent sealing performance. A first opening is added to the molding area of ​​the sealing strip in this application, allowing the decorative panel to be inserted into the molding area through the first opening, making the installation of the decorative panel simpler and faster, eliminating the need for complex assembly tools and steps, and improving production efficiency. After the decorative panel is inserted into the molding area through the opening, the installation structure is hidden, making the door surface simpler and flatter, improving the overall appearance and aesthetics of the vehicle. A bolt is movably installed on the decorative panel, with one end extending through the molding area, providing an additional fixing point for the decorative panel, enhancing its stability and preventing it from loosening or falling off due to vibration during vehicle operation. The design of the movable bolt makes the disassembly and replacement of the decorative panel more convenient and faster, reducing maintenance costs and time.

[0006] In some embodiments of this application, the sealing strip is provided with a second opening adapted to the bolt, through which the bolt passes to connect with the decorative panel.
