Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive flush-frame sealing strip and a flush-frame car door. Background Technology

[0002] With the continuous development of the automotive industry, consumers have placed higher demands on the appearance design, performance, and comfort of automobiles. Flush-frame doors, as an innovative door structure, are gradually gaining market attention due to their advantages such as improving vehicle aesthetics, reducing wind resistance, and decreasing noise. However, existing flush-frame door sealing strips still have some problems in practical applications and require further optimization to meet higher usage requirements.

[0003] In existing technologies, such as the Chinese patent application "A flush-frame car door assembly and its installation method", publication number CN119659493A, a method is disclosed that includes a sheet metal part, a decorative panel, a sealing strip, and a glass slider. The decorative panel includes a base strip and a stop strip. One end of the base strip has a horizontal U-shaped structure, referred to as a U-shaped part. The sealing strip includes a U-shaped groove. The base strip is fixed to the sheet metal part. The U-shaped groove of the sealing strip is installed into the U-shaped groove of the base strip. The glass slider is embedded into the U-shaped groove. The bottom plate of the stop strip is attached to the horizontal plate and moved towards the U-shaped part until the buckle is embedded into the slot, and the stop strip and the base strip are engaged. The baffle on the stop strip acts on the long strip of the sealing strip, causing the long strip of the sealing strip to bend into a horizontal L-shaped structure. The first recess of the long strip is located at the bottom of the baffle, and the second recess of the long strip is located at the top of the baffle. The decorative panel is divided into two parts, which facilitates the installation of the sealing strip and the glass slider, and ensures the structural stability and reliability of the decorative panel after installation.

[0004] Traditional flush-frame door seals typically employ a complex assembly structure connected to the door's fixed guide rail. While this design ensures a certain degree of stability, it presents numerous inconveniences during actual assembly. For instance, assembling the seal with the guide rail requires precise alignment and complex procedures, increasing assembly time and cost, and potentially leading to assembly errors that affect the seal's sealing performance and lifespan. Furthermore, some existing seal designs are inadequate in terms of glass sliding performance. The glass can easily be obstructed by the seal during sliding, resulting in uneven movement or even jamming, affecting the normal use of the window and reducing the user experience. Utility Model Content

[0005] The technical problem to be solved by this application is to provide an automotive flush-frame sealing strip and a flush-frame car door, which simplifies the assembly process of the sealing strip, improves the smoothness of glass sliding, and ensures good sealing performance.

[0006] The technical solution adopted in this application is: a flush-mount sealing strip for automobiles, including a U-shaped strip and a base strip. The U-shaped strip includes a short strip, a bottom strip, and a long strip connected in sequence. The inner side of the short strip, the top surface of the bottom strip, and the inner side of the long strip are all covered with a wear-resistant layer. The U-shaped strip contacts the glass slider through the wear-resistant layer. One end of the base strip is connected to the top of the short strip, and the other end of the base strip is connected to the end strip. The end strip has a horizontal Y-shaped structure. The bottom surface of the end strip contacts and connects to the guide rail. The bottom surface of the bottom strip and the outer side of the long strip are in contact with the guide rail.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, the sealing strip structure of this application eliminates the complex assembly structure of traditional sealing strips and fixed guide rails. Through the contact connection between the end strip and the guide rail, and the limiting installation of the U-shaped strip, the sealing strip can be installed more conveniently in the corresponding part of the car door. This simplified design reduces the need for precise alignment and complex operation steps during assembly, lowering the assembly difficulty. Due to the simplified assembly process, assembly time is shortened. In mass production, this can significantly improve production efficiency and reduce production costs. At the same time, it reduces assembly errors caused by assembly complexity, ensuring the stability and reliability of the sealing strip after installation, and avoiding subsequent problems such as decreased sealing performance due to assembly issues.

[0008] Secondly, a wear-resistant layer is applied to the inner sides of the short strip, the top surface of the bottom strip, and the inner sides of the long strip of the U-shaped strip. This wear-resistant layer contacts the glass slider, effectively reducing the coefficient of friction between the glass slider and the sealing strip during sliding. Compared to traditional sealing strips without a wear-resistant layer, the glass slider moves more smoothly during lifting and sliding, reducing sliding resistance and preventing uneven or even jammed glass movement, thus improving the user experience of the car window. The wear-resistant layer ensures more even and stable contact between the glass slider and the sealing strip during sliding. This optimized contact method reduces potential obstacles to the glass slider during sliding, further ensuring smooth glass movement and extending the service life of both the sealing strip and the glass slider.

[0009] Furthermore, the connection structure between the base strip and the end strip, as well as the transverse Y-shaped structure of the end strip, provides stable support for the sealing strip. This stable structural design ensures that the sealing strip maintains its shape and position during vehicle door use (such as window raising and lowering, door opening and closing operations), preventing deformation or displacement due to external forces, thus guaranteeing that the sealing strip maintains good sealing performance throughout its entire service life.

[0010] Furthermore, the bottom surface of the bottom strip and the outer surface of the long strip contact and connect with the guide rail. This multi-point contact design ensures a tight fit between the sealing strip and the guide rail. Compared to a single-contact design, this multi-point contact method can better adapt to guide rails of different shapes and sizes, improve the sealing performance of the sealing strip, effectively prevent external dust and moisture from entering the interior of the door, and ensure the airtightness of the interior of the door.

[0011] In this application, for ease of description, the accompanying drawings are used. Figure 1 The description is based on the reference, but does not imply the orientation of this application in actual use.

[0012] In some embodiments of this application, the top edge of the end strip is provided with a first lip, and the junction of the end strip and the base strip is provided with a second lip. Both the first lip and the second lip are inclined toward the side where the U-shaped strip is located.

[0013] The first and second lips are angled towards the side where the U-shaped strip is located, allowing them to fit tightly against the window glass or door structure, forming a multi-layered seal. This effectively prevents the entry of external dust, moisture, and air, improving the door's sealing performance. The angled first and second lips can better adapt to the shape changes of the window glass in different positions, ensuring a good seal throughout the window's operation and reducing seal failure caused by changes in window position.

[0014] Specifically, the first and second lips are positioned nearly parallel, and they will act on the vehicle window. This near-parallel arrangement allows for even pressure distribution when the first and second lips contact the window, preventing deformation or damage to the sealing strip due to excessive localized stress and extending its lifespan. The parallel lip arrangement also ensures more stable contact with the window, reducing loosening of the sealing strip due to window vibration or movement and ensuring long-term stability of the sealing performance.

[0015] In some embodiments of this application, both sides of the bottom strip extend outward with protruding ridges, which act on the guide rail.

[0016] The raised ridge design increases the contact friction between the U-shaped strip and the guide rail, which better secures the sealing strip in place and prevents it from shifting or loosening due to external forces during use. The tight contact between the raised ridge and the guide rail further reduces air and moisture leakage, improving the sealing performance between the sealing strip and the guide rail and ensuring the airtightness of the door interior.

[0017] In some embodiments of this application, the top surface of the long strip is connected to an L-shaped top strip, and the top surface of the top strip is provided with a third lip, which is inclined toward the base strip.

[0018] The third lip acts on the end face of the window. Inclined towards the base strip, the third lip fits tightly against the end face of the window, forming a multi-layered sealing structure. This design further enhances the door's sealing performance, effectively preventing the entry of external dust, moisture, and air.

[0019] The flush-frame car door includes a guide rail and the aforementioned flush-frame sealing strip. The guide rail has an overall L-shaped structure and includes an integrally formed base plate and side plate. The base plate is a plate structure that is bent vertically. The top surface of the side plate is folded outward to form a flange. The end strip, base strip, short strip, and bottom strip are all installed on the base plate, and the long strip is attached to the side plate wall.

[0020] Compared with existing technologies, the advantages of this application are as follows: First, the guide rail has an overall L-shaped structure, including a one-piece molded base plate and side plates. This integrated design provides higher structural strength and stability. Compared with a split structure, the one-piece molded guide rail reduces the possibility of loosening or deformation at the connection points, ensuring that the guide rail maintains a stable shape and position during long-term use, providing a reliable installation base for the sealing strip. The top surface of the side plate is folded outward to form a flange. This flange design increases the lateral strength and rigidity of the guide rail. During use in the car door, the flange can effectively resist the action of lateral forces, preventing the side plate from deforming or bending, thereby ensuring the stability of the overall guide rail structure and further ensuring a tight fit between the sealing strip and the guide rail.

[0021] Secondly, the end strip, base strip, short strip, and bottom strip are all mounted on the base plate. This design allows each part of the sealing strip to fit tightly into the base plate of the guide rail. The up-and-down bending structure of the base plate provides sufficient installation space and support for the sealing strip, ensuring accurate positioning and fixation during installation, reducing installation errors, and improving the compatibility between the sealing strip and the guide rail.

[0022] Finally, due to the relatively simple structural design of the guide rails and sealing strips, and the direct bonding or installation method between the components, the assembly process of the flush-frame door is much simpler and faster. Compared to complex assembly structures, this design reduces installation steps and required tools, lowering installation difficulty and cost.

[0023] In some embodiments of this application, the base plate includes a first segment, a second segment, a third segment, a fourth segment, and a fifth segment connected in sequence. The top surface of the first segment is in contact with the end strip. The base strip is installed at the location of the second and third segments. The U-shaped strip is installed in the installation space formed by the fourth and fifth segments and the side plate.

[0024] The segmented design of the base plate provides clearly defined installation positions for each component of the sealing strip, ensuring accurate installation and reducing assembly errors. This segmented design also provides reasonable installation space for each component, ensuring a compact and stable overall structure.

[0025] In some embodiments of this application, the cross-section of the first segment and the cross-section of the third segment are located on the same horizontal plane, the second segment is recessed and disposed below the first segment and the third segment, and a plurality of reinforcing plates are regularly arranged on the top surface of the second segment and the third segment, and the bottom surface of the base strip is in contact with the reinforcing plates.

[0026] The reinforcing plate enhances the structural strength of the base plate, especially at the base strip installation location, ensuring that the base strip will not loosen or deform under external forces during use. The contact connection between the base strip and the reinforcing plate further strengthens the installation stability of the base strip, ensuring the stability of the sealing strip during long-term use.

[0027] In some embodiments of this application, the reinforcing sheet is arranged along the width direction of the base plate, the reinforcing sheet is perpendicular to the top surface of the base plate, and multiple reinforcing sheets are arranged parallel to each other.

[0028] The parallel arrangement of the reinforcing plates evenly distributes the force on the base plate, preventing deformation or damage caused by excessive local stress and improving the overall strength of the base plate. Reinforcing plates perpendicular to the top surface of the base plate effectively enhance its bending resistance, ensuring stability during long-term use and extending its service life.

[0029] In some embodiments of this application, the fourth segment is connected below the third segment, the fifth segment is connected to the fourth segment and the side plate on both sides, the fifth segment is set below the surface of the second segment, and the U-shaped strip is in contact with the fourth segment, the fifth segment and the side plate.

[0030] The design of the fourth and fifth sections provides reasonable installation space for the U-shaped strip. Through multi-point contact, the tight connection between the U-shaped strip and the fourth, fifth, and side panels can further enhance the sealing performance and effectively block the influence of the external environment on the interior of the door.

[0031] In some embodiments of this application, the fourth segment is provided with a plurality of first buckles, which are spaced apart. A first slot is provided below the first buckle. The side plate is provided with a plurality of second buckles, which are spaced apart. A second slot is provided below the second buckle. The first buckles and the second buckles are staggered. The first buckles and the second buckles act on the U-shaped strip.

[0032] Specifically, the first and second undercuts act on the upper part of the protruding edges on both sides of the U-shaped strip. The first and second undercuts work together to align the protruding edges with the flat frame sealing strip to achieve a good assembly effect.

[0033] The design of the first and second undercuts allows for a tight fit with the protruding ridges on the U-shaped strip, ensuring a secure fit on the guide rail and preventing loosening or displacement. The staggered undercut design better adapts to the shape and size of the U-shaped strip, ensuring good fixation under various assembly conditions and improving the adaptability and reliability of the assembly.

[0034] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

Detailed Implementation

[0038] The present application will now be described in detail with reference to the accompanying drawings.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] Automotive flush frame sealing strip, Example 1 as follows Figure 1 , Figure 2 As shown: The system includes a U-shaped strip 1 and a base strip 2. The U-shaped strip 1 comprises a short strip 11, a bottom strip 12, and a long strip 13 connected in sequence. The inner surface of the short strip 11, the top surface of the bottom strip 12, and the inner surface of the long strip 13 are all covered with a wear-resistant layer 3. The U-shaped strip 1 contacts the glass slider through the wear-resistant layer 3. This design effectively reduces the coefficient of friction between the glass slider and the sealing strip during sliding. Compared to traditional sealing strips without the wear-resistant layer 3, the glass slider moves more smoothly during lifting or sliding, reducing sliding resistance and preventing uneven or even jammed glass sliding, thus improving the user experience of the car window. The wear-resistant layer 3 ensures more uniform and stable contact between the glass slider and the sealing strip during sliding. This optimized contact method reduces potential obstacles to the glass slider during sliding, further ensuring smooth glass sliding and extending the service life of both the sealing strip and the glass slider.

[0041] One end of the base strip 2 is connected to the top of the short strip 11, and the other end of the base strip 2 is connected to the end strip 4. The end strip 4 has a horizontal Y-shaped structure, which provides stable support for the sealing strip. This stable structural design allows the sealing strip to maintain its shape and position during the use of the car door (such as window raising and lowering, door opening and closing, etc.), and will not deform or shift due to external forces, thus ensuring that the sealing strip maintains good sealing performance throughout its service life.

[0042] The bottom surface of the end strip 4 contacts and connects with the guide rail 20, and the bottom surface of the bottom strip 12 and the outer surface of the long strip 13 also contact and connect with the guide rail 20. The sealing strip structure of this application eliminates the complex assembly structure of the traditional sealing strip and fixed guide rail 20. Through the contact connection between the end strip 4 and the guide rail 20, and the limiting installation of the U-shaped strip 1, the sealing strip can be installed more conveniently in the corresponding part of the car door. This simplified design reduces the need for precise alignment and complex operation steps during assembly, lowering the assembly difficulty. Due to the simplified assembly process, assembly time is shortened. In mass production, this can significantly improve production efficiency and reduce production costs. At the same time, it reduces assembly errors caused by assembly complexity, ensuring the stability and reliability of the sealing strip after installation, and avoiding subsequent problems such as decreased sealing performance due to assembly issues.

[0043] In this application, for ease of description, the accompanying drawings are used. Figure 1 The description is based on the reference, but does not imply the orientation of this application in actual use.

[0044] Example 2, as Figures 1 to 2 As shown, the top edge of the end strip 4 is provided with a first lip 5, and the junction of the end strip 4 and the base strip 2 is provided with a second lip 6. Both the first lip 5 and the second lip 6 are inclined towards the side where the U-shaped strip 1 is located. The inclined arrangement of the first lip 5 and the second lip 6 towards the side where the U-shaped strip 1 is located allows them to fit tightly against the window glass or door structure, forming a multi-layer seal, effectively blocking the entry of external dust, moisture, and air, and improving the sealing performance of the door. The inclined arrangement of the first lip 5 and the second lip 6 can better adapt to the shape changes of the window glass in different positions, ensuring a good sealing effect throughout the window raising and lowering process, and reducing sealing failure caused by changes in window position.

[0045] Specifically, the first lip 5 and the second lip 6 are arranged nearly parallel to each other, and they will act on the vehicle window. This near-parallel arrangement allows the first and second lips 5 and 6 to distribute pressure evenly when in contact with the vehicle window, preventing deformation or damage to the sealing strip due to excessive localized force, and extending the service life of the sealing strip. The parallel arrangement of the lips also ensures more stable contact with the vehicle window, reducing loosening of the sealing strip due to window vibration or movement, and ensuring long-term stability of the sealing performance.

[0046] Both sides of the bottom strip 12 extend outwards with protruding ridges 7, which act on the guide rail 20. The design of the protruding ridges 7 increases the contact friction between the U-shaped strip 1 and the guide rail 20, which can better fix the position of the sealing strip on the guide rail 20 and prevent the sealing strip from shifting or loosening due to external forces during use. The tight contact between the protruding ridges 7 and the guide rail 20 can further reduce the leakage of air and moisture, improve the sealing performance between the sealing strip and the guide rail 20, and ensure the airtightness of the inside of the door.

[0047] The top surface of the elongated strip 13 is connected to an L-shaped top strip 8, and the top surface of the top strip 8 is provided with a third lip 9, which is inclined towards the base strip 2. The third lip 9 will act on the end face of the window. The inclination of the third lip 9 towards the base strip 2 allows it to fit tightly against the end face of the window, forming a multi-layer sealing structure. This design further enhances the sealing performance of the door, effectively preventing the entry of external dust, moisture, and air.

[0048] The rest of the contents of Example 2 are the same as those of Example 1.

[0049] Flush-frame car door, Example 3, as follows Figures 3 to 5As shown, the system includes a guide rail 20 and a flush-mount sealing strip for automobiles as described in Embodiment 1 or Embodiment 2. The guide rail 20 has an overall L-shaped structure and includes an integrally formed base plate 21 and side plates 22. This integrated design provides higher structural strength and stability. Compared to a split structure, the integrally formed guide rail 20 reduces the possibility of loosening or deformation at the connection points, ensuring that the guide rail 20 maintains a stable shape and position during long-term use, providing a reliable installation base for the sealing strip. The top surface of the side plate 22 is folded outward to form a flange 23. This flange 23 design increases the lateral strength and rigidity of the guide rail 20. During use of the car door, the flange 23 can effectively resist lateral forces, preventing the side plate 22 from deforming or bending, thereby ensuring the overall structural stability of the guide rail 20 and further ensuring a tight fit between the sealing strip and the guide rail 20.

[0050] The base plate 21 is a plate structure with vertical bends, and the top surface of the side plate 22 is folded outward to form a flange 23. The end strip 4, base strip 2, short strip 11, and bottom strip 12 are all installed on the base plate 21, and the long strip 13 is attached to the wall of the side plate 22. This design allows all parts of the sealing strip to be tightly integrated with the base plate 21 of the guide rail 20. The vertical bend structure of the base plate 21 provides sufficient installation space and support for the sealing strip, ensuring that the sealing strip can be accurately positioned and fixed during installation, reducing installation errors, and improving the compatibility between the sealing strip and the guide rail 20.

[0051] Example 4, as Figures 3 to 5 As shown, the base plate 21 includes a first segment 211, a second segment 212, a third segment 213, a fourth segment 214, and a fifth segment 215 connected sequentially. The top surface of the first segment 211 is in contact with the end strip 4. The base strip 2 is installed at the positions of the second segment 212 and the third segment 213. The U-shaped strip 1 is installed within the installation space formed by the fourth segment 214, the fifth segment 215, and the side plate 22. The segmented design of the base plate 21 provides clear installation positions for each component of the sealing strip, ensuring accurate installation and reducing assembly errors. The segmented design provides reasonable installation space for each component of the sealing strip, ensuring a compact and stable overall structure.

[0052] The cross-section of the first segment 211 and the cross-section of the third segment 213 are on the same horizontal plane. The second segment 212 is recessed and positioned below the first segment 211 and the third segment 213. Multiple reinforcing plates 24 are regularly arranged on the top surfaces of the second segment 212 and the third segment 213. The bottom surface of the base strip 2 is in contact with the reinforcing plates 24. The reinforcing plates 24 enhance the structural strength of the base plate 21, especially at the installation position of the base strip 2, ensuring that the base strip 2 will not loosen or deform due to external forces during use. The contact connection between the base strip 2 and the reinforcing plates 24 further enhances the installation firmness of the base strip 2, ensuring the stability of the sealing strip during long-term use.

[0053] The reinforcing plates 24 are arranged along the width direction of the base plate 21, perpendicular to the top surface of the base plate 21, and multiple reinforcing plates 24 are arranged parallel to each other. The parallel arrangement of the reinforcing plates 24 can evenly distribute the force on the base plate 21, preventing deformation or damage caused by excessive local stress, and improving the overall strength of the base plate 21. The reinforcing plates 24 perpendicular to the top surface of the base plate 21 can effectively enhance the bending resistance of the base plate 21, ensuring the stability of the base plate 21 during long-term use and extending its service life.

[0054] The fourth segment 214 is connected below the third segment 213. The fifth segment 215 connects the fourth segment 214 to the side panel 22 on both sides. The fifth segment 215 is positioned lower than the surface where the second segment 212 is located. The U-shaped strip 1 is in contact with the fourth segment 214, the fifth segment 215, and the side panel 22. The design of the fourth segment 214 and the fifth segment 215 provides reasonable installation space for the U-shaped strip 1. Through multi-point contact, the tight connection between the U-shaped strip 1 and the fourth segment 214, the fifth segment 215, and the side panel 22 can further enhance the sealing performance and effectively block the influence of the external environment on the interior of the door.

[0055] The fourth segment 214 is provided with multiple first buckles 25, which are spaced apart. A first slot 26 is formed below each first buckle 25. The side plate 22 is provided with multiple second buckles 27, which are spaced apart. A second slot 28 is formed below each second buckle 27. The first buckles 25 and second buckles 27 are staggered. The first buckles 25 and second buckles 27 act on the U-shaped strip 1. Specifically, the first buckles 25 and second buckles 27 act above the protruding edges 7 on both sides of the U-shaped strip 1. The first buckles 25 and second buckles 27, in conjunction with the protruding edges 7, align the flat frame sealing strip to achieve a good assembly effect.

[0056] The design of the first and second buckles 25 allows them to fit tightly with the protruding ribs 7 on the U-shaped strip 1, ensuring a secure fit of the U-shaped strip 1 on the guide rail 20 and preventing loosening or displacement. The staggered buckle design better adapts to the shape and size of the U-shaped strip 1, ensuring good fixing under different assembly conditions and improving the adaptability and reliability of the assembly.

[0057] The rest of the contents of Example 4 are the same as those of Example 3.

[0058] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
