Description

Technical Field

[0001] This utility model relates to the field of vehicle door sealing technology, and in particular to a quick-install zero-surface-difference vehicle door sealing system. Background Technology

[0002] Car doors are a crucial component of a vehicle, not only providing passengers with access but also playing a key role in the vehicle's exterior design, safety, and comfort. Modern car doors are typically made of high-strength metal materials, such as steel or aluminum alloys, to ensure durability and excellent impact resistance. The interior of a car door integrates various functional components, including window regulators, door locking mechanisms, airbags, and audio speakers. Door design emphasizes a close fit with the car body, effectively isolating external noise and weather through precise engineering and advanced sealing technologies, thus enhancing interior comfort. Furthermore, the exterior styling of the doors directly impacts the overall aesthetics of the vehicle; smooth lines and refined details are key factors in attracting consumers. In short, car doors are not only the "face" of a car but also complex components that combine functionality and aesthetics.

[0003] Zero-face-difference doors are an advanced automotive door design. Their core feature is that the side components of the door are flush with the A-side of the moving glass, achieving a zero-face-difference effect. This design not only makes the door appearance smoother and more mirror-like, enhancing the vehicle's aesthetics, but also effectively reduces the drag coefficient and wind noise, improving the vehicle's NVH performance. The zero-face-difference door system optimizes the design of the sealing strips and guide rails to ensure the stability of the moving glass during raising and lowering, resulting in better sealing. Compared to traditional doors, it has no special requirements for sheet metal processing and glass thickness, reducing manufacturing and assembly costs. Furthermore, zero-face-difference doors improve driver visibility and reduce blind spots. The application of this technology brings significant advantages to automotive exterior design and performance enhancement.

[0004] For example, a zero-face difference car door system with application number CN202221375054.2 in the prior art has the following technical points: it includes a mounting base and a lifter. The mounting base includes a lower base and an upper frame set on it. The upper frame is divided into a fixed corner window mounting position and a movable glass mounting position. The lifter is set on the lower base. The key feature is that a zero-face difference corner window is provided in the fixed corner window mounting position. The movable glass mounting position includes two door pillars, namely a first door pillar and a second door pillar. A first guide rail sealing strip is provided next to the first door pillar. A trim panel is provided on the outside of the second door pillar. A second guide rail sealing strip is provided on the inside of the trim panel. A movable glass assembly driven by the lifter is installed in the movable glass mounting position. The movable glass assembly consists of a movable glass and at least one first double-material injection molding slider and at least one second double-material injection molding slider respectively provided on its two side edges. The first double-material injection molding slider and the second double-material injection molding slider are both composed of a supporting adhesive surface and an arc-shaped sliding part injected on it. The first double-material injection molded slider has a support bonding surface including a bonding part and a Y-direction positioning part connected thereto. The Y-direction positioning part has several arc-shaped sliding parts injection molded on it. The bonding part of the first double-material injection molded slider is bonded to one edge of the inner side of the movable glass, and the Y-direction positioning part of the first double-material injection molded slider is located inside the first guide rail sealing strip. The second double-material injection molded slider has a support bonding surface including a bonding part and X-direction positioning parts and Y-direction positioning parts connected thereto. The X-direction positioning parts and Y-direction positioning parts have several arc-shaped sliding parts injection molded on them respectively. The bonding part of the second double-material injection molded slider is bonded to the other edge of the inner side of the movable glass, and the X-direction positioning parts and Y-direction positioning parts of the second double-material injection molded slider are located inside the second guide rail sealing strip respectively. During the lifting and lowering of the movable glass, the first double-material injection molded slider, the first guide rail sealing strip, the second double-material injection molded slider, and the second guide rail sealing strip limit the X-direction and Y-direction trajectories. The outer surface of the movable glass is flush with the outer surface of the corner window glass of the zero-plane difference corner window and the outer surface of the decorative panel, respectively.

[0005] As can be seen from the above, current zero-face difference car doors typically use a guide rail sealing strip next to the door pillar and a slider that slides within the guide rail sealing strip and connects to the door glass. However, the current guide rail sealing strip is installed inside the guide rail. Specifically, the zero-face difference corner window adopts an integrated injection-molded edge-sealed zero-face difference corner window, which consists of a guide rail sealing strip installed inside the guide rail and corner window glass integrated onto it through an edge-sealing injection molding process; the first guide rail sealing strip is installed inside the guide rail of the zero-face difference corner window, and the first guide rail sealing strip is provided with a hook. The guide rail is provided with a locking platform that matches the hook. The first guide rail sealing strip is locked inside the guide rail, and the guide rail sealing strip is made of TPV and EPDM materials.

[0006] However, because the guide rail sealing strip uses a high hardness of SHA80 or higher, it is easy for the guide rail sealing strip and the guide rail to collide, squeeze and rub against each other during assembly. This not only makes it difficult to assemble the entire structure, but also causes damage between the structures, which may lead to water leakage in the internal structure of the zero-surface difference door. However, if the guide rail sealing strip is made of a soft material, it may not be able to be firmly installed in the guide rail. Therefore, it is necessary to improve the current guide rail sealing strip and guide rail structure to reduce the assembly difficulty while still ensuring its sealing effect.

[0007] Therefore, a quick-install zero-surface-difference door sealing system is proposed to solve or alleviate the above problems. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] During assembly, the sealing strip of this invention is first embedded between the upper and lower guide rails. The insertion part and the deformation part form an arrow-shaped structure and deform, pre-fixing it within the anti-detachment protrusion. Further embedding occurs, with the limiting part and the elastic part undergoing elastic deformation. After embedding into the limiting protrusion, the elastic part releases potential energy, firmly fixing the sealing strip and providing waterproofing. The U-shaped strip of the water-blocking strip is fitted over the outer side of the lower guide rail extension strip, and is fixed after deformation. Depending on requirements, the inner or outer lip of the sealing strip, or the outer bubble tube part, can be used for waterproofing. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0036] A quick-install zero-surface-difference door sealing system, such as Figure 1 and Figure 2 As shown, it includes a lower guide rail 1, an upper guide rail 3 located at the upper end of the lower guide rail 1, a water-blocking strip 2 installed on one side of the lower guide rail 1, a guide rail sealing strip 4 that can be embedded in the upper guide rail 3 and the lower guide rail 1, and a sliding post 501 slidably connected in the guide rail sealing strip 4. The sliding post 501 is fixedly connected to a slider 502 that can be connected to the glass. The guide rail sealing strip 4 has elastic deformation properties and is made of TPV material with a Shore hardness of less than 70 degrees.

[0037] One side of the guide rail sealing strip 4 has two sets of outwardly protruding limiting parts 401 integrally formed. When the guide rail sealing strip 4 is embedded in the upper guide rail 3 and the lower guide rail 1, the limiting parts 401 prevent the guide rail sealing strip 4 from leaving. The inner ring of the upper guide rail 3 is fixedly connected to two upper limit protrusions 301, and the inner ring of the lower guide rail 1 is fixedly connected to two lower limit protrusions 101. The distance between adjacent upper limit protrusions 301 and the distance between adjacent lower limit protrusions 101 are both less than the maximum distance between the two sets of limiting parts 401. The guide rail sealing strip 4 located between the two sets of limiting parts 401 has an elastic part 402 that abuts against the inner ring of the upper guide rail 3 and the lower guide rail 1.

[0038] An insertion part 404 is integrally formed on the side of the guide rail sealing strip 4 away from the limiting part 401. A deformation part 405 is integrally formed on the end of the insertion part 404 away from the guide rail sealing strip 4. When the guide rail sealing strip 4 is embedded in the upper guide rail 3 and the lower guide rail 1, the insertion part 404 and the deformation part 405 are embedded in the upper guide rail 3 and the lower guide rail 1, and the deformation part 405 prevents the guide rail sealing strip 4 from leaving. Two upper anti-detachment protrusions 302 are fixedly connected to the inner ring of the upper guide rail 3, and two lower anti-detachment protrusions 102 are fixedly connected to the inner ring of the upper guide rail 3. The distance between adjacent upper anti-detachment protrusions 302 and the distance between adjacent lower anti-detachment protrusions 102 are gradually increased from the opening. The insertion part 404 and the deformation part 405 are embedded between adjacent upper anti-detachment protrusions 302 and adjacent lower anti-detachment protrusions 102.

[0039] The outer ring of the guide rail sealing strip 4 is fixedly connected with several protrusions 403 that abut against the inner rings of the upper guide rail 3 and the lower guide rail 1. The length of the guide rail sealing strip 4 is equal to the sum of the lengths of the lower guide rail 1 and the upper guide rail 3. The side of the guide rail sealing strip 4 near the limiting part 401 is fixedly connected with an outer bubble tube part 4061 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1. The side of the guide rail sealing strip 4 near the insertion part 404 is fixedly connected with an inner lip edge part 407 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1.

[0040] like Figure 5 and Figure 6 As shown, the lower guide rail 1 is fixedly connected to an extension strip, and the water-blocking strip 2 includes a U-shaped part 201, a plurality of protruding strips 202 fixedly connected to the inner ring of the U-shaped part 201, and an outer baffle 203 fixedly connected to the outer side of the U-shaped part 201. The U-shaped part 201 is sleeved on the outer side of the extension strip, and the protruding strips 202 are abutted against the extension part. Example 2:

[0041] The difference from Example 1 is that,

[0042] like Figure 3 and Figure 4 As shown, the guide rail sealing strip 4 has an outer lip 4062 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the limiting part 401, and an inner lip 407 that extends to the outer side of the upper guide rail 3 and the lower guide rail 1 fixedly connected to the side near the insertion part 404.

[0043] During actual assembly, the guide rail sealing strip 4 is first embedded between the upper guide rail 3 and the lower guide rail 1. At this time, the insertion part 404 and the deformation part 405 on the guide rail sealing strip 4 can form an arrow-shaped structure. After the deformation part 405 and the insertion part 404 deform, they enter between the upper anti-detachment protrusion 302 and the lower anti-detachment protrusion 102, so that one side of the guide rail sealing strip 4 can be pre-fixed in the upper guide rail 3 and the lower guide rail 1. Then, the guide rail sealing strip 4 is further embedded into the upper guide rail 3 and the lower guide rail 1, so that the two sets of limiting parts 401 on the guide rail sealing strip 4 can undergo elastic deformation, and the elastic part 402 can also undergo elastic deformation for compression. When the limiting part 401 is embedded in the upper limit protrusion 301 of the inner ring of the upper guide rail 3 and the lower guide rail 1, When the lower limit protrusion 101 is in place, the elastic part 402 can release elastic potential energy, so that the guide rail sealing strip 4 can be firmly restricted in the upper guide rail 3 and the lower guide rail 1, and it is not easy to fall out. Since the length of the guide rail sealing strip 4 is equal to the sum of the lengths of the lower guide rail 1 and the upper guide rail 3, the guide rail sealing strip 4 itself can play an effective waterproof role, preventing rainwater on the glass from entering the car door when it flows with the slider 502 and the sliding column 501, but can be blocked by the guide rail sealing strip 4. Then, the opening of the U-shaped strip of the water-blocking strip 2 is aligned with the extension strip of the lower guide rail 1, and then the U-shaped strip is put on the outside of the extension strip, and the protrusion 202 therein can be deformed, so that the water-blocking strip 2 can be firmly installed on the outside of the extension strip.

[0044] Furthermore, depending on the specific application requirements, the inner lip edge 407 on one side of the guide rail sealing strip 4 can be bonded to the glass for waterproofing, while the outer lip edge 4062 or the outer bubble tube 4061 on the other side can be used for waterproofing and shielding.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
