[0031] The following is combined Figures 1 to 4 This invention describes the door opening sealing strip structure, the vehicle door opening sealing assembly, and the carrier according to embodiments of the present invention.
[0032] According to an embodiment of this utility model, in one aspect, a door opening sealing strip structure is provided, suitable for installation on the side panel sheet metal stop 12 of a vehicle body, mainly composed of solid adhesive, sponge adhesive, etc. Specifically, as... Figure 1 As shown, the door opening sealing strip structure includes a sealing strip body 1 and a sealing bubble tube 3. Figure 3 As shown, the sealing strip body 1 is used to snap onto the side panel sheet metal stop 12 of the vehicle body. The sealing strip body 1 has an internal skeleton 2 for support and shaping, ensuring that the sealing strip body 1 maintains a stable shape during installation and use. This allows the sealing strip body 1 to fit tightly against the side panel sheet metal stop 12 of the vehicle body, guaranteeing its sealing effect. Furthermore, the addition of the skeleton 2 significantly enhances the strength and durability of the sealing strip body 1, enabling it to resist the impact of door closure and wear during long-term use, extending its service life. Optionally, the skeleton 2 is a metal skeleton, such as a steel strip skeleton or an aluminum strip skeleton. The skeleton 2 generally adopts a segmented skeleton to adapt to the needs of different vehicle models and door opening shapes, improving the adaptability and flexibility of the sealing strip body 1. In addition, the sealing strip body 1 also has copper wires 11 inside, which work in conjunction with the segmented steel strip skeleton to reduce the shrinkage of the sealing strip body 1, allowing it to better fit the door opening and maintain its sealing effect.
[0033] like Figure 1As shown, the sealing bubble tube 3 is located on one side of the sealing strip body 1, and the sealing bubble tube 3 is provided with vent holes 4. It can be understood that the door opening sealing strip is arranged around the entire side of the vehicle body, with the vent holes 4 evenly distributed around the entire circle to ensure smooth venting after compression and deformation of the sealing bubble tube 3. Their number and spacing can be determined according to actual design requirements. Furthermore, the sealing bubble tube 3 has at least one water-stop rib 5 on its outer wall facing away from the sealing strip body 1. It can be understood that the outer wall of the sealing bubble tube 3 facing away from the sealing strip body 1 is used to abut against the door sheet metal 13; that is, the outer wall of the sealing bubble tube 3 in contact with the door sheet metal 13 has at least one water-stop rib 5. Figure 4 As shown, when the door sheet metal 13 compresses and seals the bubble tube 3, the water-stop rib 5 fits tightly against the door sheet metal 13. It should be noted that the number of water-stop ribs 5 can be determined according to actual design requirements.
[0034] With this configuration, the door opening sealing strip structure is snapped onto the side panel sheet metal stop 12 of the vehicle body. By arranging at least one water-stopping rib 5 on the outer wall of the sealing bubble tube 3, when the door is closed and the sealing bubble tube 3 is compressed and deformed, the water-stopping rib 5 can increase the friction between the sealing bubble tube 3 and the door sheet metal 13, allowing the sealing bubble tube 3 to reliably fill the gap between the door and the side panel stop of the vehicle body, thereby effectively blocking water flow from the outside of the door and ensuring the sealing and waterproof performance of the door opening sealing strip structure. At the same time, after the sealing bubble tube 3 is compressed and deformed, the vent hole 4 can ensure smooth venting of the sealing bubble tube 3, thereby improving the smoothness of opening and closing the door and enhancing the quality of vehicle door closing.
[0035] Optionally, in some embodiments of this utility model, such as Figure 3 As shown, the cross-section of the sealing strip body 1 has a U-shaped groove structure. And as... Figure 2 As shown, a first adhesive portion 6 is provided on the inner side of the side wall 101 near the sealing bubble tube 3 of the U-shaped groove structure, and a second adhesive portion 7 is provided on the inner side of the bottom wall 102 of the U-shaped groove structure. Specifically, the first adhesive portion 6 and the second adhesive portion 7 are made of highly viscous materials such as hot melt butyl rubber and butyl rubber, which not only form a strong adhesive force but also prevent stringing during use, thereby improving the quality and appearance of the product.
[0036] This design, through the U-shaped groove structure, allows the sealing strip body 1 to reliably engage with the side panel sheet metal stop 12 of the vehicle body, tightly wrapping the edge of the door opening and ensuring a good seal at the side panel sheet metal stop. Simultaneously, the first adhesive portion 6 ensures that the side of the sealing strip body 1 closest to the door is tightly bonded to the side panel sheet metal, preventing it from easily falling off or loosening during long-term use and preventing water from the outside of the door from seeping into the vehicle interior through this connection point. Furthermore, the second adhesive portion 7 ensures that the bottom of the groove of the sealing strip body 1 is also tightly bonded to the side panel sheet metal. If water from the outside of the door seeps into the welded gaps of the chassis sheet metal, the second adhesive portion 7 prevents the water from seeping into the vehicle interior through the sealing strip body 1.
[0037] Furthermore, in some embodiments of this utility model, such as Figure 3 As shown, at least one clamping tooth 8 is also provided on the inner side of the sidewall 101 of the U-shaped groove structure. Optionally, as... Figure 2 As shown, clamping teeth 8 are arranged on the inner sides of both sidewalls 101 of the U-shaped groove structure, and each sidewall 101 has at least one clamping tooth 8. The clamping teeth 8 can be composed of solid adhesive and sponge adhesive to provide a stable clamping base and ensure the tightness and adaptability of the clamping. It should be noted that the number of clamping teeth 8 can be determined according to the actual design requirements.
[0038] This design, with its clamping teeth 8, increases the contact area and friction between the sealing strip body 1 and the side panel sheet metal stop 12, enhancing the clamping force and ensuring that the sealing strip body 1 is firmly attached to the side panel sheet metal stop 12 after installation. This prevents loosening or detachment, improving installation stability and thus enhancing the door's sealing performance. It effectively prevents rainwater, dust, noise, and other external factors from entering the vehicle, improving the interior environment. Furthermore, during installation, the sealing strip body 1 is simply inserted into the side panel sheet metal stop 12, and the clamping teeth 8 automatically engage and fix it, making the installation process simpler and faster, simplifying the installation operation.
[0039] Optionally, in some embodiments of this utility model, the diameter of the vent hole 4 is 2.5 mm to 5 mm. For example, the diameter of the vent hole 4 can be 2.5 mm, 3 mm, 4 mm, or 5 mm, or any value between two values. This is only an example and is not a specific limitation. This setting, by reasonably controlling the size of the vent hole 4, ensures the structural performance of the sealing bubble tube 3 while allowing the gas inside the sealing bubble tube 3 to be smoothly discharged, thereby ensuring smooth opening and closing of the door. If the diameter of the vent hole 4 is too small, for example, less than 2.5 mm, it will affect the venting effect of the sealing bubble tube 3. If the diameter of the vent hole 4 is too large, for example, greater than 5 mm, it will result in insufficient space for the arrangement of the vent hole 4, poor perceived quality of the product, reduced visual effect of the product, and affect the overall appearance of the door opening sealing strip. Additionally, it will result in insufficient ballast, leading to a weaker closing force.
[0040] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, the sealed bubble tube 3 includes a first bubble tube 301 and a second bubble tube 302 connected to each other, and both the first bubble tube 301 and the second bubble tube 302 are provided with vent holes 4. Figure 3 As shown, the second bubble tube 302 is located outside the sealing strip body 1, and the first bubble tube 301 is located outside the second bubble tube 302. This arrangement gives the sealing bubble tube 3 a double-bubble design, providing strong sidewall support, maintaining a good seal, and offering a double sealing effect. When compressed by the door, it can more reliably fill the gap between the door and the side panel stop, improving overall sealing performance. Both bubble tubes are equipped with vent holes 4, allowing for the smooth expulsion of internal air when the sealing bubble tube 3 is compressed, thus reducing resistance when the door closes and making opening and closing the door smoother.
[0041] In addition, as an optional implementation method, such as Figure 2 As shown, a notch 15 is provided at the connection between the first bubble tube 301 and the second bubble tube 302. Thus, as... Figure 4 As shown, when the car door is closed, the first bubble tube 301 and the second bubble tube 302 are deformed by squeezing. Under the action of the notch 15, the sealing bubble tube 3 is more likely to deform, which increases the contact area between the sealing bubble tube 3 and the car door, thereby improving the sealing effect of the sealing bubble tube 3 on the car door, and does not increase the resistance when the car door is closed.
[0042] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, the first bubble tube 301 is provided with a first cavity 3011, which is connected to the exhaust port 4 so that when compressed, the gas in the first cavity 3011 can be discharged from the exhaust port 4, improving the closing quality. Furthermore, the inner wall of the first cavity 3011 is provided with a first protrusion 3012, the number of which can be determined according to actual design requirements.
[0043] like Figure 2 As shown, the second bubble tube 302 is provided with a second cavity 3021, which is connected to the exhaust port 4 so that when compressed, the gas in the second cavity 3021 can be discharged from the exhaust port 4, improving the smoothness of opening and closing the door. Furthermore, the inner wall of the second cavity 3021 is provided with a second protrusion 3022, the number of which can be determined according to actual design requirements. Optionally, the first protrusion 3012 and the second protrusion 3022 are designed as arc-shaped protrusions.
[0044] This design, by arranging protruding structures on the inner walls of the cavities of the first bubble tube 301 and the second bubble tube 302, effectively prevents the inner wall surfaces of the first bubble tube 301 and the second bubble tube 302 from sticking together when compressed by the car door. This reduces wear or damage to the sealing bubble tube 3 that may occur due to sticking during long-term use, extends the service life of the sealing strip, and maintains a good sealing effect.
[0045] Optionally, in some embodiments of this utility model, such as Figure 3 As shown, the sealing bubble tube 3 is also equipped with an arc-shaped sealing lip 9, which overlaps with the interior trim 14 and bends towards the sealing strip body 1. This arrangement, with the arc-shaped sealing lip 9 overlapping the interior trim 14, forms an additional sealing barrier, blocking the gap between the trim and the sealing strip. This effectively prevents external substances such as air, moisture, and dust from seeping into the vehicle interior, thus improving the overall sealing effect. Furthermore, the arc design allows the sealing lip to better adapt to the shape and position of the interior trim 14. Regardless of whether the surface of the interior trim 14 is flat or curved, the arc-shaped sealing lip 9 can fit tightly against it, forming an effective seal. Moreover, the design of the arc-shaped sealing lip 9 not only considers the above functionality but also aesthetics. Its smooth lines and harmonious matching with the interior trim 14 serve a decorative purpose while ensuring sealing functionality, enhancing the overall appearance quality of the vehicle.
[0046] Furthermore, in some embodiments of this utility model, such as Figure 3As shown, a pull cord 10 is provided on the side of the arc-shaped sealing lip 9 near the sealing strip body 1. Optionally, the pull cord 10 is composed of solid adhesive and fiberglass. This arrangement, through the addition of the pull cord 10, increases the operational flexibility of the arc-shaped sealing lip 9 while maintaining its sealing performance. The pull cord 10 can serve as a guide or auxiliary tool during the installation process. When installing the door opening sealing strip, the arc-shaped sealing lip 9 can be straightened by pulling out the pull cord 10, allowing it to reliably overlap with the interior trim 14, reducing the lip edge from getting caught in the trim, ensuring its sealing effect, making the operation more convenient, reducing manual rework time, simplifying and maximizing the adjustment process, facilitating production and installation, and improving the product's practicality.

Optionally, the vehicle is a vehicle, a low-altitude aircraft, etc. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-described door opening sealing assembly, and therefore will not be repeated here.
