[0002] In the prior art, the current frameless door sealing strip structure mainly includes two types of whole type and split type. The whole type is selected by Japanese cars, Volkswagen and Audi in European cars, and the split type is selected by Benz and BMW in European cars. The whole type frameless door sealing system has less parts, better integrity, but has too many cross sections and joint angles, complex structure process, high cost of joint angle, additional B column support, and the support and joint angle cannot be universalized due to the influence of vehicle size and shape.

[0003] The frameless door sealing system has complex structure and high matching difficulty. When designing, the water blocking path, water drainage path, door closing force, door closing sound, NVH and other factors need to be fully considered. In addition, considering the design and manufacturing factors, the integrity of the sealing system and the generalization degree of the cross section also need to be ensured.

[0004] The car model with C column corner window will cause the black edge of the corner window at the C column to be too large, which will increase the opaque area between the rear door glass and the corner window glass from the visual sense, and the visible area should be increased as much as possible from the aesthetic point of view. Therefore, a C column body structure is adopted to reduce the opaque area. However, the C column type will cause the rear door hole sealing strip to have a section without clamping support.

[0036] In order to provide a split type frameless door sealing system scheme without C-pillar, the present application provides a sealing strip structure and a sealing device, and the present application is specifically implemented by the following technical solutions.

[0037] Embodiment 1

[0038] Combined with Figures 5 to 12 , the sealing strip structure in the present embodiment 1 includes a first sealing strip, the first sealing strip includes a first stop portion 11, a second stop portion 12, a third stop portion 13, a first clamping portion 21 and a second clamping portion 22, the first stop portion 11, the second stop portion 12 and the third stop portion 13 are all used for abutting against the vehicle window glass 70, the first stop portion 11 is connected with the second stop portion 12, the first clamping portion 21 is connected with the first stop portion 11, the first clamping portion 21 is used for being connected with the injection molding part 60 and the guide rail 50, the second clamping portion 22 is connected with the second stop portion 12 and the third stop portion 13 respectively, the second clamping portion 22 is used for clamping the guide rail 50, and the first stop portion 11 is also used for abutting against the guide rail 50.

[0039] This embodiment 1 is applied to a car body sheet metal without a C-pillar. The first sealing strip can be installed at the C-pillar. Since there is no sheet metal 5 at the C-pillar, in this embodiment 1, the second snap-fit ​​part 22 is snapped onto the guide rail 50, and the guide rail 50 is connected to the injection molded part 60, thereby installing the first sealing strip onto the car body sheet metal without a C-pillar. The second snap-fit ​​part 22 is connected to the second stop part 12, so that the first sealing strip forms a whole, which is convenient for installation.

[0040] The sealing strip structure provided in Embodiment 1 can be connected to the glass via guide rail 50 and injection molded part 60, and the sealing strip structure does not need to be connected to the body sheet metal 5; the sealing strip structure provided in Embodiment 1 can be applied to body sheet metal without C-pillar; according to Figure 7 It can be seen that after using the sealing strip structure in Embodiment 1, the visible width at the C-pillar is less than or equal to 50mm, which is small and has a good visual effect.

[0041] The visible area of ​​a vehicle after body paneling with a C-pillar structure in existing technology is shown in the following diagram. Figure 11 As shown. When this embodiment 1 is applied to a car body sheet metal structure without a C-pillar, the visible area of ​​the vehicle at the C-pillar is shown in the diagram. Figure 12 As shown. According to Figure 11 and Figure 12 As can be seen from the comparison, using this embodiment 1 can significantly increase the visible area and optimize the visual effect of the visible area.

[0042] Furthermore, the first side of the second snap-fit ​​portion 22 is provided with a first protrusion 31, and the second side of the second snap-fit ​​portion 22 is provided with a second protrusion 32. The first side of the second snap-fit ​​portion 22 and the second side of the second snap-fit ​​portion 22 are arranged opposite to each other, and the first protrusion 31 and the second protrusion 32 are respectively used to snap-fit ​​the guide rail 50.

[0043] In this embodiment 1, the second snap-fit ​​part 22 is snapped onto the guide rail 50 by the first protrusion 31 and the second protrusion 32.

[0044] Furthermore, the first side of the second snap-fit ​​portion 22 is also provided with a groove 40, which is used to accommodate the end of the guide rail 50.

[0045] In this embodiment 1, the first protrusion 31 is engaged with the end of the guide rail 50. After the first protrusion 31 is engaged with the end of the guide rail 50, the end of the guide rail 50 can be accommodated in the groove 40, thus avoiding positional interference between the sealing strip and the guide rail 50.

[0046] Furthermore, the first engaging portion 21 is provided with a third protrusion 33, which is used to engage the guide rail 50. In this embodiment 1, the first engaging portion 21 is engaged with the guide rail 50 by the third protrusion 33.

[0047] In this embodiment 1, the third protrusion 33 is horizontally engaged with the guide rail 50, so that the first sealing strip is located at the upper limit of the horizontal direction on the guide rail 50; the first protrusion 31 and the second protrusion 32 are vertically engaged with the guide rail 50, so that the first sealing strip is located at the upper limit of the vertical direction on the guide rail 50.

[0048] In this embodiment 1, the hardness of the second stop 12, the hardness of the third stop 13, and the hardness of the third protrusion 33 are all less than the hardness of the first snap-fit ​​part 21 and the hardness of the second snap-fit ​​part 22. The second stop 12, the third stop 13, and the third protrusion 33 are made of soft rubber, while the first snap-fit ​​part 21 and the second snap-fit ​​part 22 are made of hard rubber. In this embodiment 1, both the first stop 11 and the third stop 13 are provided with anti-shrinkage glass fiber 110.

[0049] Furthermore, it also includes a second sealing strip, which includes a fourth stop portion 14, a third snap-fit ​​portion 23, and a fourth snap-fit ​​portion 24. The fourth stop portion 14 is used to abut against the window glass 70. The third snap-fit ​​portion 23 is provided with a snap-fit ​​groove 230 for snapping the sheet metal 5. The opening of the snap-fit ​​groove 230 is located on the first side of the third snap-fit ​​portion 23. The fourth snap-fit ​​portion 24 is connected to the second side of the third snap-fit ​​portion 23 and bends towards the second side of the third snap-fit ​​portion 23. A snap-fit ​​cavity 40 is formed between the second side of the third snap-fit ​​portion 23 and the fourth snap-fit ​​portion 24 for snapping the interior trim panel.

[0050] In this embodiment 1, the second sealing strip can be installed at the door opening seal other than the C-pillar and connected to the sheet metal 5. The third snap-fit ​​part 23 is snapped onto the sheet metal 5 through the snap-fit ​​groove 230. The fourth snap-fit ​​part 24 is connected to the second side of the third snap-fit ​​part 23 and bent towards the second side of the third snap-fit ​​part 23. A snap-fit ​​cavity 40 is formed between the second side of the third snap-fit ​​part 23 and the fourth snap-fit ​​part 24, and the interior panel is snapped into the snap-fit ​​cavity 40. According to Figure 9 As can be seen, after using the sealing strip structure in Embodiment 1, the exposed black edge width is 12.5mm, which is small and has a good visual effect. In Embodiment 1, the fourth stop part 14 is provided with anti-shrinkage glass fiber 110.

[0051] In this embodiment 1, the third snap-fit ​​part 23 is also provided with an assembly pull wire 41. The assembly pull wire 41 is used for assembly, and the third snap-fit ​​part 23 can be pulled out and attached to the interior panel through the assembly pull wire 41.

[0052] Furthermore, it also includes a third sealing strip, which includes a fifth stop portion 15, a sixth stop portion 16, and a fifth snap-fit ​​portion 25. The fifth stop portion 15 and the sixth stop portion 16 are connected and both are used to abut against the window glass 70. The fifth snap-fit ​​portion 25 is connected to the fifth stop portion 15 and is used to connect with the injection molded part 60. The fifth stop portion 15 is also used to abut against the injection molded part 60.

[0053] In this embodiment 1, both the third sealing strip and the second sealing strip can be installed at the door opening seal outside the C-pillar, and there is no direct connection between the third sealing strip and the second sealing strip.

[0054] Furthermore, the first end of the first sealing strip is connected to the first end of the second sealing strip and the first end of the third sealing strip, respectively, and the second end of the first sealing strip is connected to the second end of the second sealing strip and the second end of the third sealing strip, respectively.

[0055] During the processing of the sealing strip, various irregularly shaped sealing strip materials can be individually manufactured and then connected using a corner-joining mold to form a corner between the two sealing strip materials. This allows the sealing strip structure provided in Embodiment 1 to be integrated into a single unit. The first sealing strip is then installed at the C-pillar, and its cross-sectional structure is as follows: Figure 5 The cross-sectional structure at point AA; second and third sealing strips are installed on parts other than the C-pillar, the cross-sectional structure of the second sealing strip is as follows. Figure 5 The cross-sectional structure at point BB.

[0056] The sealing strip structure provided in Embodiment 1 is a rear door opening sealing strip 98. Further, the vehicle body also includes a side panel trim strip 91, an upper side panel sealing strip 92, a B-pillar trim panel sealing strip 93, a front door opening sealing strip 94, a front first-stage sealing strip 95, a front inner water-cutting sealing strip 96, a front outer water-cutting sealing strip 97, a rear first-stage sealing strip 99, a rear inner water-cutting sealing strip 991, and a rear outer water-cutting sealing strip 992. The side panel trim strip 91, the upper side panel sealing strip 92, the B-pillar trim panel sealing strip 93, the front door opening sealing strip 94, the front first-stage sealing strip 95, the front inner water-cutting sealing strip 96, the front outer water-cutting sealing strip 97, the rear first-stage sealing strip 99, the rear inner water-cutting sealing strip 991, and the rear outer water-cutting sealing strip 992 are all single-section. This invention has a simple structure, excellent overall integrity of the sealing system, and a high degree of standardization in system cross-sections.

[0057] For body sheet metal structures without a C-pillar, since the side sheet metal 5 does not have a sheet metal 5 stop joint sealing strip at the C-pillar, this invention chooses to use a new type of sealing strip with a new cross section at the C-pillar of conventional models, and integrates a metal guide rail 50 on the corner window for joint support, thereby achieving sealing between the sealing strip and the inner surface of the glass and the side of the glass, which not only meets the sealing requirements, but also reduces the size of the opaque area at the C-pillar of conventional models (the model matched by this invention does not have a C-pillar, which means the C-pillar position corresponding to conventional models).

[0058] Compared with an integrated frameless door sealing system, the present invention has fewer joints and cross-sections, resulting in lower cost and higher parts commonality. Compared with a split frameless door sealing system, the present invention can be applied to body panels without a C-pillar, with fewer individual parts, better overall parts integrity, and no need to consider the collapse problem of the wing joints extending from the C-pillar sealing strip. It can also achieve a small rounded corner turn at the top of the C-pillar, optimizing passenger access, reducing overall vehicle weight and cost, minimizing the width of the C-pillar, and optimizing the visible area.

[0059] This invention features a small number of parts, good overall integrity, simple cross-section, and high system versatility. It can be applied to C-pillarless body sheet metal structures, shortening the C-pillar width and optimizing the visual effect; the C-pillarless sheet metal structure and C-pillarless interior trim structure reduce overall vehicle weight and lower costs; a small rounded corner can be achieved at the top of the C-pillar, facilitating passenger access; and a special sealing strip structure conceals the gap between the rear door glass and the rear corner window glass at the C-pillar location, achieving a seamless appearance.

[0060] This invention solves the problem of the lack of sheet metal support at the C-pillar, reduces the width of the C-pillar, improves the accessibility of the rear door for passengers, reduces the overall vehicle weight, and lowers the cost of interior trim panels. This invention boasts advantages such as excellent sealing performance, good visual appeal, good overall integrity, strong versatility, and a high degree of platform integration, making it well-suited for platform strategies with clear trends.

[0062] Combination Figures 5 to 12 As shown, this embodiment 2 provides a sealing device, including an injection molded part 60, a guide rail 50, and a sealing strip structure as in embodiment 1. The injection molded part 60 is connected to the car window glass 70 and the guide rail 50 respectively. The first snap-fit ​​part 21 of the sealing strip structure is snapped between the injection molded part 60 and the guide rail 50. The first stop part 11 of the sealing strip structure abuts against the guide rail 50, and the second snap-fit ​​part 22 of the sealing strip structure is snapped into the guide rail 50.

[0063] In this embodiment 2, the first sealing strip of the sealing strip structure is connected to the guide rail 50 and the injection molded part 60 respectively, thereby realizing the connection between the first sealing strip and the glass. The first sealing strip is thus installed at the C-pillar without needing to be connected to the sheet metal 5. This embodiment 2 can be applied to body sheet metal without a C-pillar.

[0064] In this embodiment 2, the sealing strip structure can be connected to the glass via the guide rail 50 and the injection molded part 60, and the sealing strip structure does not need to be connected to the body sheet metal 5; this embodiment 2 can be applied to body sheet metal without a C-pillar; according to Figure 7 It can be seen that after using this embodiment 2, the visible width at the C-pillar is less than or equal to 50mm, which is small and has a good visual effect.

[0065] The visible area of ​​a vehicle after body paneling with a C-pillar structure in existing technology is shown in the following diagram. Figure 11 As shown in the figure. When this embodiment 2 is applied to a car body sheet metal structure without a C-pillar, the visible area of ​​the vehicle at the C-pillar is shown in the figure below. Figure 12 As shown.

[0066] Furthermore, the guide rail 50 includes a first slot and a second slot, a second engaging portion 22 is engaged in the first slot, and a first engaging portion 21 is engaged between the injection molded part 60 and the second slot;

[0067] The first slot includes a first receiving plate 511, a first connecting plate 521, and a second receiving plate 512. The first receiving plate 511 is disposed on the first side of the first connecting plate 521, and the second receiving plate 512 is disposed on the second side of the first connecting plate 521. The first receiving plate 511 is bent in a first direction, and the second receiving plate 512 is bent in a second direction. The first direction and the second direction are opposite.

[0068] The second slot includes a second connecting plate 522 and a third connecting plate 523. The second connecting plate 522 is arranged along the first direction. The first side of the second connecting plate 522 is connected to the second snap-fit ​​plate 512. The second side of the second connecting plate 522 is connected to the first side of the third connecting plate 523. An angle is provided between the third connecting plate 523 and the second connecting plate 522.

[0069] In this embodiment 2, the second snap-fit ​​part 22 is snapped into the first slot, the first protrusion 31 of the second snap-fit ​​part 22 is snapped into the first snap-fit ​​plate 511 of the first slot, and the second protrusion 32 is snapped into the second snap-fit ​​plate 512 of the first slot. The first snap-fit ​​part 21 is snapped between the injection molded part 60 and the second slot.

[0070] Furthermore, the included angle between the third connecting plate 523 and the second connecting plate 522 is in the range of 90° to 120°. The included angle range in this embodiment 1 is adapted to the first snap-fit ​​portion 21 of the sealing strip, where 90° ≤ included angle ≤ 120°.

[0071] Furthermore, the second connecting plate 522 is provided with a protrusion 520 for resisting the sealing strip. Furthermore, the first engaging portion 21 of the sealing strip is provided with a third protrusion 33, which is used to engage the guide rail 50. In this embodiment 1, the first engaging portion 21 is engaged with the protrusion 520 by the third protrusion 33, thereby further securing the first engaging portion 21 to the guide rail 50.

[0072] Furthermore, the guide rail 50 also includes a fourth connecting plate 524, the first side of which is connected to the second side of the third connecting plate 523, the second side of which abuts against the second snap-fit ​​plate 512, and the second side of the second connecting plate 522 abuts against the fourth connecting plate 524. The fourth connecting plate 524 is used to connect with the injection molded part 60.

[0073] In this embodiment 1, the guide rail 50 is connected to the injection molded part 60 via the fourth connecting plate 524. Preferably, the first slot is also connected to the injection molded part 60, further realizing a reliable connection between the guide rail 50 and the injection molded part 60.

[0074] Furthermore, the second side of the third connecting plate 523 is bent in the first direction and connected to the first side of the fourth connecting plate 524, with the third connecting plate 523 abutting against the fourth connecting plate 524.

[0076] Furthermore, the guide rail 50 is a roll-formed guide rail 50.

[0077] For body sheet metal structures without C-pillars, since the side sheet metal 5 does not have a sheet metal 5 stop joint sealing strip at the C-pillar, this invention chooses to use a new type of sealing strip with a new cross section at the C-pillar of conventional models, and integrates a metal guide rail 50 on the corner window for joint support, thereby achieving sealing between the sealing strip and the inner surface of the glass and the side of the glass, which not only meets the sealing requirements, but also reduces the size of the opaque area at the C-pillar of conventional models.

[0078] Compared with an integrated frameless door sealing system, the present invention has fewer joints and cross-sections, resulting in lower cost and higher parts commonality. Compared with a split frameless door sealing system, the present invention can be applied to body panels without a C-pillar, with fewer individual parts, better overall parts integrity, and no need to consider the collapse problem of the wing joints extending from the C-pillar sealing strip. It can also achieve a small rounded corner turn at the top of the C-pillar, optimizing passenger access, reducing overall vehicle weight and cost, minimizing the width of the C-pillar, and optimizing the visible area.

[0079] This invention features a small number of parts, good overall integrity, simple cross-section, and high system versatility. It can be applied to C-pillarless body sheet metal structures, shortening the C-pillar width and optimizing the visual effect; the C-pillarless sheet metal structure and C-pillarless interior trim structure reduce overall vehicle weight and lower costs; a small rounded corner can be achieved at the top of the C-pillar, facilitating passenger access; and a special sealing strip structure conceals the gap between the rear door glass and the rear corner window glass at the C-pillar location, achieving a seamless appearance.

[0080] This invention solves the problem of the lack of sheet metal support at the C-pillar, reduces the width of the C-pillar, improves the accessibility of the rear door for passengers, reduces the overall vehicle weight, and lowers the cost of interior trim panels. This invention boasts advantages such as excellent sealing performance, good visual appeal, good overall integrity, strong versatility, and a high degree of platform integration, making it well-suited for platform strategies with clear trends.

[0081] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
