Description

Technical Field

[0001] This invention mainly relates to the field of automotive sealing system technology, specifically to a door gap sealing and matching structure and vehicle. Background Technology

[0002] With the development of automobiles, in recent years, car exterior designs have become more fashionable, and the types of door structures have become increasingly diverse. More and more models use glass or high-gloss covers at the corners of the doors. The matching relationship between the rear corner of the door and the side glass at the door seam has received attention from OEMs and users.

[0003] like Figure 1 As shown, existing automotive door gap fitting structures mainly utilize door gap strips, inner door and window panels, corner window glass, and side window glass. The door gap strip surface is equipped with a snap-fit ​​structure that allows the inner door and window panel to be installed. Simultaneously, one end of the door gap strip can form a seal with the edge trim of the side window glass when the door is closed. Position a represents the normal sealing position, and position b represents the faulty position.

[0004] but Figure 1 The structure is constrained by the sheet metal structure, and the distance between the snap-fit ​​position and the edge banding is relatively far, posing a risk of snap-fit ​​detachment and loosening. This structure is also prone to causing scratching noises and edge curling during door opening and closing, especially noticeable when the door gap is small. Secondly, when the vehicle is traveling at high speed or the door is closed quickly, a momentary air pressure difference may occur between the inside and outside of the door. This air pressure difference can impact the sealing strip, potentially causing momentary vibration of the sealing lip, generating wind noise, or increasing the resistance to closing the door.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] This invention relates to a matching sealing structure for the door gap sealing strip between the rear corner window glass and the side corner window glass of a vehicle door. As a crucial component of the vehicle door system, the door gap sealing strip is installed on the edge of the door sheet metal and mates with the outer corner window glass. Besides achieving a basic aesthetic appearance, it must also fulfill a sealing function (waterproofing and dustproofing), with increasingly higher overall requirements and functionalities. Therefore, designing a simple and reliable door gap sealing strip structure is of great significance. Example See attached document Figures 2a-2b A door gap sealing and matching structure includes a door window frame inner panel 20, a door window frame reinforcing plate 30, a door corner window glass 40, a door gap strip 10, a side window glass 50, and an edge-sealing drape 51 installed on the door window; the door window frame inner panel 20 and the door window frame reinforcing plate 30 are embedded in the door gap strip 10; one surface of the door gap strip 10 is connected to the door corner window glass 40, and forms an interference seal with the edge-sealing drape 51 when the door is closed.

[0022] It should be noted that the door seam strip 10, as an important component of the car door system, is installed on the edge of the door sheet metal stop and cooperates with the outer corner window glass. In addition to achieving the basic appearance, it also needs to take into account the sealing (waterproof and dustproof) function, and the overall requirements and functions are becoming increasingly higher.

[0023] The door seam strip 10 includes a door seam strip body, an installation reference surface 1, a U-shaped metal frame 2, an inner sealing part 3, and an outer sealing part 4. The door seam strip body has an overall U-shaped design, with the bottom surface of its U-shaped structure serving as the installation reference surface 1, providing a stable positioning base for overall installation. The U-shaped metal frame 2 is internally assembled inside the door seam strip body, and its main function is to enhance the structural strength of the door seam strip body, ensuring that it is not easily deformed after installation and maintaining sealing stability. The inner sealing part 3 is located on the inner surface of the door seam strip body and is adapted to the fixedly embedded inner panel 20 of the door window frame and the reinforcing plate 30 of the door window frame, achieving inner sealing through tight fit. The outer sealing part 4 is located on the outer surface of the door seam strip body and forms a sealed connection with the corner window glass 40 of the door, effectively isolating external wind, rain, and noise, and ensuring the airtightness and quietness of the vehicle interior. During installation, the door seam strip body and the installation reference surface 1 of the U-shaped bottom surface should be used as the positioning reference to ensure that the door seam strip is installed flat as a whole. The inner sealing part 3 should be completely fitted with the inner panel 20 of the door window frame and the reinforcing plate 30 of the door window frame, and the outer sealing part 4 should be tightly connected with the corner window glass 40 of the door to avoid gaps that may affect the sealing effect.

[0024] Additionally, the edge-sealing drape 51 is located at one end of the side window glass 50, allowing for slight inward and outward movement during door opening and closing. Furthermore, a sliding material 5 is provided on the rear part of the door seam strip 10 (the side that forms an interference seal with the edge-sealing drape 51). These two components work together to prevent the drape from curling and producing noise. Specifically, the open end of the door seam strip 10 faces the inner panel 20 of the door window frame and the reinforcing plate 30 of the door window frame, while the sliding material 5 is installed on the outer surface of the closed end. like Figure 3 As shown, the interior of the door seal strip body is provided with a micro-pressure balance channel 6; one end of the micro-pressure balance channel 6 opens into the outer sealing part 4, and the other end opens into the inner side of the mounting reference surface 1; a waterproof and breathable membrane 7 is provided on the inner wall of the micro-pressure balance channel 6. When the car door closes quickly, the air pressure inside the car increases instantaneously, and the high-pressure air will enter through the inner opening of the micro-pressure balance channel 6 and slowly discharge to the outside of the car through the waterproof and breathable membrane 7, thereby balancing the pressure and allowing the car door to close easily and without impact noise; when the vehicle is traveling at high speed, the negative pressure formed in a specific area outside the car can also be slowly balanced through the micro-pressure and the waterproof and breathable membrane 7, preventing the door seal strip 10 from being sucked up and causing vibration.

[0025] In this embodiment, refer to the appendix Figure 4 The surface of the U-shaped metal frame 2 is coated with an anti-rust coating 8, and the closed end of the U-shaped metal frame 2 is filled with damping material 9, which effectively improves the corrosion resistance and rigidity of the U-shaped metal frame 2. The two internal toothed lips of the inner sealing part 3 adopt a differentiated structure from the outer cloak.

[0026] In this embodiment, refer to the appendix Figure 4 A stop rib 21 is formed on the surface of the inner panel 20 of the door window frame. This stop rib 21 is embedded in the U-shaped structure of the door seam strip body and faces the inner sealing part 3. The mounting reference surface 1 cooperates with the stop rib 21 on the inner panel 20 of the door window frame to provide a positioning reference and prevent it from falling out. The U-shaped metal frame 2 is clamped between the door sheet metal. The open end of the metal frame 2 is clamped between the inner panel 20 of the door window frame and the door window frame reinforcing plate 30, and the closed end extends to the middle of the cross-section of the door seam strip 10. The U-shaped metal frame 2 can provide anti-opening holding force and strengthen the structural resistance to deformation.

[0027] In this embodiment, refer to the appendix Figure 2b The inner sealing part 3 has two internal toothed lips and an exterior cloak. The exterior cloak has flexible reinforcing strips embedded inside, effectively improving its wind resistance and maintaining a smooth appearance. The exterior cloak provides an interference seal with the inner panel 20 of the door and window frame. The outer sealing part 4 has three internal toothed lips, providing an interference seal with the corner window glass 40 of the door. The two internal toothed lips of the inner sealing part 3 and the exterior cloak employ a differentiated structure. The internal toothed lips provide sealing and holding force; the exterior cloak matches the appearance of the inner panel 20 of the door and window frame.

[0028] In this embodiment, refer to the appendix Figure 2b and attached Figure 5 The sliding material 5 and the door seam strip 10 are integrally co-extruded and contact each other with the edge trim 51 during the opening and closing of the car door, eliminating friction noise. The distance between the edge trim 51 and the mounting reference surface 1 of the door seam strip 10 is less than the height of the door seam strip 10 at the mounting reference surface 1, forming a non-cantilever structure to avoid sealing failure caused by door gap deviation. The three inner toothed lips of the outer sealing part 4 of the door seam strip 10 form three sealing barriers with the corner window glass 40 of the car door in sequence; forming the main path for rainwater blocking, reducing the water pressure load on the inner sealing strip of the car door; a guide groove 11 is opened at the bottom of the outer sealing part 4 of the door seam strip 10 to guide and drain the infiltrated rainwater.

[0029] This invention relates to a novel door seam sealing and matching structure. This structure offers reliable installation and, through its internal structural design, mates with the door sheet metal to achieve excellent sealing performance and aesthetic quality. When the car door is closed, the vent and the edge vent 51 interfere with each other, creating a seal and obstructing the view. This effectively prevents rainwater from entering the vehicle, reducing pressure on the internal door seal strip. Simultaneously, it effectively conceals gaps between the door and surrounding components, preventing edge curling and rattling issues. It satisfies the sealing strip's own sealing requirements while also enhancing appearance and other functions, thus improving overall vehicle performance and product competitiveness. By integrating a micro-pressure balance channel 6 and a waterproof and breathable membrane 7, it solves the problems of high-speed wind noise and door closing pressure balance while maintaining the door seam sealing performance, significantly improving vehicle performance and the feel of closing the door.

[0030] The aforementioned door seam sealing and matching structure can be integrated into various vehicles, such as automobiles (including pure electric vehicles and hybrid vehicles) and trucks.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
