Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a B-pillar sealing structure and a vehicle. Background Art

[0002] As users' demands for vehicle appearance become increasingly stringent, the number of vehicles equipped with frameless door systems is increasing. Consequently, the requirements for the performance and aesthetics of the door's sealing structure are also increasing. The B-pillar sealing structure, as a component of the door's sealing structure, has a significant impact on the overall sealing performance and aesthetics of the vehicle. In related art, the B-pillar sealing structure has a large exposed area of ​​the seal, which reduces the overall aesthetics of the vehicle. Furthermore, the door is prone to wear after prolonged use, resulting in poor reliability of the B-pillar sealing structure. Summary of the Invention

The first retaining plate is located on a side opposite the first surface area and is connected to the exterior panel body. The first retaining plate and the exterior panel body enclose a first mounting groove, with the opening of the first mounting groove facing the outer periphery of the exterior panel body. The second connecting portion is secured within the first mounting groove.

[0007] In some possible implementations of the first aspect, the first surface region includes a first edge segment that forms a portion of an outer edge of the exterior panel. The second sealing portion includes a first sealing segment that extends along the first edge segment and connects to the second surface region; and the first connecting portion is connected to the first sealing segment.

[0008] In some possible implementations of the first aspect, the exterior trim panel also includes a flange, which is connected to the outer edge of the exterior trim panel body and extends toward the side opposite to the first surface area; the surface of the flange opposite to the first surface area forms a part of the second surface area and is connected to the first sealing section.

[0009] In some possible implementations of the first aspect, the first connecting portion includes a first connecting segment and a second connecting segment. The first connecting segment has two ends connected to two ends of the first sealing segment, respectively. The second connecting segment is located within a space enclosed by the first connecting segment and the first sealing segment, and is connected to both the first connecting segment and the first sealing segment.

[0010] In some possible implementations of the first aspect, the first connecting segment has a first limiting hole, or the second connecting segment has a first limiting hole, and the second surface area has a first limiting protrusion, which is fitted and accommodated in the first limiting hole.

[0011] In some possible implementations of the first aspect, the second surface area has a first snap-fit ​​structure. The first connecting portion includes a second snap-fit ​​structure, and the second snap-fit ​​structure snaps into engagement with the first snap-fit ​​structure to connect the second sealing member to the first end.

[0012] In some possible implementations of the first aspect, the second snap-fit ​​structure includes a snap-fit ​​ring, the axis of the snap-fit ​​ring is parallel to the thickness direction of the exterior panel, and the first snap-fit ​​structure includes a snap-fit ​​protrusion, which is accommodated in the snap-fit ​​ring.

[0013] In some possible implementations of the first aspect, there are multiple first clipping structures, and the multiple first clipping structures are arranged at intervals along the width direction of the exterior panel. There are multiple second clipping structures, and ends of the multiple second clipping structures connected to the second sealing portion are arranged at intervals along the width direction of the exterior panel, and one second clipping structure is clipped to one first clipping structure.

[0014] In some possible implementations of the first aspect, an end surface of the sub-seal is flush with an end surface of the second end. The B-pillar sealing structure further includes a connector, and an end portion of the sub-seal is connected to the second end via the connector.

[0019] Furthermore, by positioning the second connection portion of the second seal on the side opposite the first surface area, the first surface area forms part of the vehicle's exterior, minimizing the exposed area of ​​the second seal and improving the vehicle's overall aesthetics. Furthermore, because the exterior trim is typically stronger than the second seal, the B-pillar seal structure is more durable, further enhancing the vehicle's overall aesthetics and reliability.

[0020] The beneficial technical effects of the vehicle provided by this application are the same as the beneficial technical effects of the B-pillar sealing structure provided by this application, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0041] Please also refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a vehicle 100 provided in some embodiments of the present application is provided. Figure 2 for Figure 1The diagram shows a partial structural diagram of a vehicle 100. Vehicle 100 includes a body 10 and multiple doors 20. A portion of the body 10 encloses a cockpit. The body 10 includes side panels 11, a B-pillar sealing structure 12, and a door opening sealing strip 13. The side panels 11 partially form the bulkhead of the cockpit. The side panels 11 have multiple door openings 10a that communicate with the cockpit and include B-pillars 111 located between adjacent door openings 10a. The doors 20 are pivotally connected to the body 10 and correspond one-to-one with the door openings 10a. When the doors 20 are open, users can enter and exit the cockpit through the door openings 10a. When the doors 20 are closed, they seal the door openings 10a, protecting the cockpit and ensuring the safety of the user and their belongings. Specifically, the doors 20 include a door body 21 and a door glass 22. The door body 21 is pivotally connected to the side panels 11.

[0042] Please also refer to Figure 2-Figure 4 , Figure 3 for Figure 2 The structural diagram of the B-pillar sealing structure 12 of the vehicle 100 is shown. Figure 4 for Figure 3 An exploded view of the B-pillar sealing structure 12 is shown. The B-pillar sealing structure 12 includes an outer trim panel 121, a first seal 122A, and a second seal 123. The outer trim panel 121 includes a first end 121A and a second end 121B arranged along its length. The first end 121A has a first surface area 121a and a second surface area 121b arranged along its thickness. Part of the edge of the first surface area forms the outer edge of the outer trim panel 121. The length of the outer trim panel 121 is generally parallel to the height of the vehicle 100, and the thickness of the outer trim panel 121 is generally parallel to the left-right direction of the vehicle 100. The second end 121B of the outer trim panel 121 faces the top of the vehicle 100. Therefore, the outer trim panel 121 is connected to the B-pillar 111, with the second surface area 121b of the outer trim panel 121 facing the B-pillar 111.

[0043] Please also refer to Figure 3-Figure 6 , Figure 5 for Figure 2 The structural diagram of the B-pillar sealing structure 12 of the vehicle 100 is shown as another perspective. Figure 6 for Figure 5An exploded view of the B-pillar sealing structure 12 is shown. The first seal 122A includes two sub-seals 122, which are connected to the ends of the exterior panel 121 along its width and extend along its length. Each sub-seal 122 includes a first sealing portion 1221, at least a portion of which is located on the outer periphery of the exterior panel 121. The two sub-seals 122 can be separate components or connected via a connecting structure to form a single, integrated component.

[0044] The second sealing member 123 includes a first connecting portion 1231 and a second sealing portion 1232. The first connecting portion 1231 is located on the side opposite the first surface area 121a and is connected to the first end 121A. The ends of the second sealing portion 1232 are respectively connected to the ends of the two sub-seal members 122. The second sealing portion 1232 extends around the first end 121A, with at least a portion located on the outer periphery of the first end 121A.

[0045] Specifically, the first seal 122A and the second seal 123 are an integral structural component. This reduces the joints between the first seal 122A and the second seal 123, preventing the risk of delamination and cracking, thereby improving the overall sealing and durability of the B-pillar sealing structure 12. In some embodiments, the sub-seal 122 can be formed through an extrusion process. In this way, the sub-seal 122 has a consistent cross-section, a smooth surface, high strength, and high manufacturing efficiency. The second seal 123 can be formed through an injection molding process and connected to the sub-seal 122 by injection molding. In this way, the second seal 123 can form a complex structure that adapts and connects to the aforementioned first end 121A, which is beneficial to improving the overall reliability of the B-pillar sealing structure 12.

[0046] In this way, the B-pillar sealing structure 12 provided in the present application connects the two ends of the outer trim panel 121 along the width direction of the outer trim panel 121 with the two sub-seals 122, and at least a portion of the first sealing portion 1221 is located on the outer peripheral side of the outer trim panel 121, so that when the vehicle door 20 is closed, the edge portion of the vehicle door glass 22 can be fitted and sealed with the first sealing portion 1221; and the second sealing portion 1232 of the second sealing member 123 extends around the first end 121A, and at least a portion of the second sealing portion 1232 is located on the outer peripheral side of the first end 121A, so that when the vehicle door 20 is closed, the vehicle door body 21 contacts the first surface area 121a and fits and seals with the second sealing portion 1232, thereby cooperating with the door opening sealing strip to ensure the sealing of the vehicle 100 to prevent dust and water vapor outside the vehicle 100 from entering the interior of the vehicle 100.

[0047] On this basis, by positioning the first connection portion 1231 of the second seal 123 on the side opposite the first surface region 121a, the first surface region 121a forms part of the exterior appearance of the vehicle 100, reducing the exposed area of ​​the second seal 123 and improving the overall aesthetics of the vehicle 100. Furthermore, because the strength of the exterior panel 121 is generally greater than that of the second seal 123, the B-pillar sealing structure 12 has improved durability, further enhancing the overall aesthetics and reliability of the vehicle 100.

[0048] Please also refer to Figure 5-Figure 7 , Figure 7 for Figure 2 A cross-sectional view of a portion of the structure of the vehicle 100 is shown at line AA. The sub-seal 122 also includes a second connecting portion 1222, which is connected to the first sealing portion 1221. Specifically, the second connecting portion 1222 extends along the length of the exterior panel 121 and is located on the side of the corresponding first sealing portion 1221 close to the other first sealing portion 1221. Based on this, the exterior panel 121 includes an exterior panel body 1211 and a first limiting plate 1212. The aforementioned first surface area 121a is formed on the exterior panel body 1211. The first limiting plate 1212 is located on the side opposite to the first surface area 121a and is connected to the exterior panel body 1211. The first limiting plate 1212 and the exterior panel body 1211 are surrounded by a first mounting groove 121c, and the opening of the first mounting groove 121c faces the outer peripheral side of the exterior panel body 1211.

[0049] Specifically, the first stopper 1212 can extend from the end connected to the exterior panel body 1211, first along the thickness direction of the exterior panel body 1211, away from the exterior panel body 1211, and then along the width direction of the exterior panel body 1211, toward the outer periphery of the exterior panel body 1211. Based on this, the second connecting portion 1222 of the subseal 122 is fixedly engaged within the first mounting groove 121c. Specifically, the second connecting portion 1222 can be snapped into the first mounting groove 121c or bonded to the inner wall surface of the first mounting groove 121c.

[0050] On this basis, the first sealing portion 1221 includes a first sealing lip 1221a and a second sealing lip 1221b. The connecting end of the first sealing lip 1221a is connected to the second connecting portion 1222, the sealing end is suspended and has an arc shape, and the center of curvature of the sealing end is located on the side of the first sealing lip 1221a facing the B-pillar 111. The second sealing lip 1221b is located between the first sealing lip 1221a and the B-pillar 111 along the thickness direction of the exterior trim panel 121. The connecting end of the second sealing lip 1221b is connected to the second connecting portion 1222, the sealing end is suspended and is located on the side of the first sealing lip 1221a away from the exterior trim panel body 1211. This sealing end is located on the outer periphery of the first limiting plate 1212 and has an arc shape, with the center of curvature located on the side of the second sealing lip 1221b facing away from the B-pillar 111. In other words, a portion of the first sealing portion 1221 is located on the outer periphery of the exterior trim panel 121. When the vehicle door 20 is closed, the outer side surface of the edge portion of the vehicle door glass 22 presses the first sealing lip 1221a to achieve sealing, and the inner surface of the edge portion of the vehicle door glass 22 presses the second sealing lip 1221b to achieve sealing.

[0051] In this way, the structural strength of the outer panel 121 is better, and the performance of resisting the impact force formed by closing the vehicle door 20 is stronger. In addition, the connection area between the second connecting portion 1222 and the outer panel 121 is larger, which can improve the connection reliability between the two.

[0052] In some other embodiments, the exterior panel 121 may not include the first limiting plate 1212 , and the first connecting portion 1231 may be connected to the exterior panel body 1211 .

[0053] Please also refer to Figure 3-Figure 6 First surface region 121a includes a first edge segment 121a1, which forms a portion of the outer edge of exterior panel 121. Accordingly, at least a portion of second sealing portion 1232 extends along first edge segment 121a1 and connects to second surface region 121b. First connecting portion 1231 connects to this portion of second sealing portion 1232.

[0054] As a result, a portion of the second sealing portion 1232 is located on the outer periphery of the exterior panel 121. When the door 20 is closed, the door body 21 compresses a portion of the second sealing portion 1232 to form a seal. Furthermore, when the B-pillar sealing structure 12 is assembled to the side panel 11, another portion of the second sealing portion 1232 is located between the exterior panel 121 and the B-pillar 111. This provides a connection framework for the first connecting portion 1231 and also cushions the exterior panel 121, preventing damage to the exterior panel 121 and the B-pillar 111 caused by hard contact due to the impact of closing the door 20.

[0055] Please continue reading Figure 3-Figure 6 The second sealing portion 1232 includes two second sealing segments 1232a and a first sealing segment 1232b. One end of the first sealing segment 1232b is connected to the end of one sub-seal 122 via the second sealing segment 1232a, and the other end of the first sealing segment 1232b is connected to the end of another sub-seal 122 via another second sealing segment 1232a. The second sealing segment 1232a includes a third sealing lip 1232a1 and a fourth sealing lip 1232a2. The third sealing lip 1232a1 is connected to the first sealing lip 1221a along the length of the exterior panel 121. The specific structure can refer to the structure of the first sealing lip 1221a. The fourth sealing lip 1232a2 is connected to the second sealing lip 1221b along the length of the exterior panel 121. The specific structure can refer to the structure of the second sealing lip 1221b.

[0056] In this way, the sealing structures corresponding to the corners of the exterior trim panel 121 are all formed on the second seal 123, so that the connection between the sub-seal 122 and the second seal 123 avoids the corners, which simplifies the design, production and connection difficulty of the sub-seal 122 and the second seal 123, and also enables the connection reliability between the sub-seal 122 and the second seal 123 to be better.

[0057] Figure 3 and Figure 6 In the illustrated embodiment, the first mounting groove 121c is located on a side of the second sealing segment 1232a away from the first sealing segment 1232b, and the second sealing segment 1232a is in contact with the outer side of the exterior panel body 1211. In other embodiments, the structure of the second sealing segment 1232a may also refer to the structure of the aforementioned sub-seal 122, with a portion of the second sealing segment 1232a snapping into the aforementioned first mounting groove 121c.

[0058] On this basis, the first sealing segment 1232b forms a fifth sealing lip, the ends of which, along its extension direction, respectively connect with the ends of the fourth sealing lips 1232a2 of the two second sealing segments 1232a. The structure of the fifth sealing lip can refer to that of the fourth sealing lips 1232a2 and will not be further described here. In other embodiments, the second sealing portion 1232 may also not include the two second sealing segments 1232a, with the ends of the first sealing segment 1232b directly connecting with the ends of the two sub-seals 122 at the corners of the exterior panel 121.

[0059] Please also refer to Figure 4 、 Figure 6 and Figure 8 , Figure 8 for Figure 2A cross-sectional view of a portion of the structure of vehicle 100 is shown along line BB. The exterior panel 121 also includes a flange 1213. The flange 1213 is connected to the outer edge of the first end 121A and extends toward the side opposite the first surface area 121a. The surface of the flange 1213 facing away from the first surface area 121a forms a portion of the second surface area 121b and adheres to at least a portion of the second sealing portion 1232. Specifically, the flange 1213 adheres to the first sealing segment 1232b of the second sealing portion 1232. It should be noted that if the second sealing portion 1232 does not include the second sealing segment 1232a, the flange 1213 adheres to the entire second sealing portion 1232. That is, a portion of the exterior panel 121 body forms a portion of the first end 121A, and the flange 1213 forms another portion of the first end 121A.

[0060] This allows for a thinner outer panel 121 and first sealing segment 1232b, while cushioning the impact of closing the vehicle door 20. This facilitates the fabrication of the outer panel 121 and second sealing member 123, and reduces the overall cost of the B-pillar sealing structure 12. Furthermore, the flange 1213 forms a mounting space with the outer panel body 1211, facilitating the arrangement of the connection structure between the first connecting portion 1231 and the outer panel 121.

[0061] Please also refer to Figure 4-Figure 6 The first connecting portion 1231 includes a first connecting section 1231a and a second connecting section 1231b. The first connecting section 1231a extends in a direction generally parallel to the width of the exterior panel 121, and its two ends are connected to the two ends of the first sealing section 1232b. The second connecting section 1231b extends in a direction generally parallel to the length of the exterior panel 121 and is located within the space enclosed by the first connecting section 1231a and the first sealing section 1232b. The second connecting section 1231b is connected to both the first connecting section 1231a and the first sealing section 1232b. In other embodiments, the first connecting section 1231a may extend in a direction that intersects with the width of the exterior panel 121 and is not perpendicular thereto; and the second connecting section 1231b may extend in a direction that intersects with the length of the exterior panel 121 and is not perpendicular thereto.

[0062] In this way, the first connecting segment 1231a and the second connecting segment 1231b can form a three-dimensional structure with the first sealing segment 1232b, thereby improving the overall structural strength of the second sealing member 123. Furthermore, the first connecting segment 1231a and the second connecting segment 1231b cooperate with the aforementioned first limiting plate 1212 to limit the movement of the second sealing member 123 relative to the outer trim panel 121 along the length of the outer trim panel 121, thereby preventing the sub-seal 122 and the second sealing member 123 from separating from the outer trim panel 121, which would result in poor reliability and durability of the overall sealing structure 12 of the B-pillar 111.

[0063] Please continue reading Figure 4-Figure 6 The second connecting section 1231b has a first limiting hole 1231c, and the second surface area 121b of the first end 121A of the exterior panel 121 has a first limiting protrusion 121d. The first limiting protrusion 121d is accommodated in the first limiting hole 1231c. Specifically, the first limiting protrusion 121d is formed on the exterior panel body 1211. In other embodiments, the first limiting hole 1231c can also be formed in the first connecting section 1231a. In this way, when the first seal 122A and the second seal 123 are assembled to the exterior panel 121, the cooperation between the first limiting hole 1231c and the first limiting protrusion 121d can provide initial positioning, thereby improving the overall assembly efficiency of the B-pillar sealing structure 12, and thereby improving the overall assembly efficiency of the vehicle 100.

[0064] Please continue reading Figure 4-Figure 6 The second surface area 121b of the first end 121A of the exterior panel 121 has a first engaging structure 121e. Specifically, the first engaging structure 121e is formed on the exterior panel body 1211. Based on this, the first connecting portion 1231 includes a second engaging structure 1231d, which engages with the first engaging structure 121e to connect the second sealing member 123 to the first end 121A of the exterior panel 121. Specifically, the second engaging structure 1231d is connected to the second sealing section 1232a of the second sealing member 123.

[0065] In this way, the second seal 123 is connected to the outer panel 121 by a snap connection, which is conducive to improving the overall assembly efficiency of the B-pillar sealing structure 12, and further improving the overall assembly efficiency of the vehicle 100. In addition, it is also convenient to disassemble the second seal 123 and the outer panel 121 for easy maintenance.

[0066] Please continue reading Figure 4-Figure 6The first clipping structure 121e includes a clipping protrusion, and the second clipping structure 1231d includes a clipping ring. The axis of the clipping ring is roughly parallel to the thickness direction of the exterior panel 121. The clipping protrusion fits in the clipping ring. Specifically, the cross-sectional shape of the clipping protrusion can be circular, triangular, quadrilateral, pentagonal, etc. On this basis, a staple can be provided on the clipping protrusion, and the exterior panel 121 can be clipped to the B-pillar 111 via the staple. In this way, the structures of the first clipping structure 121e and the second clipping structure 1231d are relatively simple, which facilitates the design, production, and assembly of the exterior panel 121 and the second seal 123. In addition, the mating surface between the first clipping structure 121e and the second clipping structure 1231d is relatively large, which makes the clipping reliability of the first clipping structure 121e and the second clipping structure 1231d better.

[0067] In some other embodiments, the first clamping structure 121e and the second clamping structure 1231d may also be L-shaped hooks, which are clamped together to connect the second sealing member 123 to the first end 121A of the exterior panel 121.

[0068] Please continue reading Figure 4-Figure 6 There are multiple first clip structures 121e, and the multiple first clip structures 121e are spaced apart along the width direction of the exterior panel 121. There are multiple second clip structures 1231d, and the ends of the multiple second clip structures 1231d connected to the second sealing portion 1232 are spaced apart along the width direction of the exterior panel 121. The second clip structures 1231d correspond one-to-one with the first clip structures 121e, and one second clip structure 1231d is clipped to one first clip structure 121e. Specifically, the multiple first clip structures 121e are located on both sides of the second connecting section 1231b along the width direction of the exterior panel 121, and the ends of the multiple second clip structures 1231d connected to the first sealing section 1232b are located on both sides of the second connecting section 1231b. The number of first clip structures 121e and second clip structures 1231d can be 2, 3, 4, etc.

[0069] In this way, by distributing the forces on the first and second clamping structures 121e and 1231d, the risk of separation of the second seal 123 from the exterior panel 121 can be reduced, thereby ensuring the overall connection reliability of the B-pillar sealing structure 12.

[0070] Please also refer to Figure 5 and Figure 9 , Figure 9 for Figure 5The B-pillar sealing structure 12 is shown in a cross-sectional view taken along line CC. The end surface of the subseal 122, distal from the second seal 123, is flush with the end surface of the second end 121B of the exterior trim panel 121. Based on this, the B-pillar sealing structure 12 also includes a connector 124, through which the end of the subseal 122 is connected to the second end 121B of the exterior trim panel 121. Specifically, the connector 124 may be a staple. The second connecting portion 1222 of the subseal 122 and the first retaining plate 1212 of the exterior trim panel 121 may both have connecting holes. The staple is inserted through the connecting holes to connect the second connecting portion 1222 to the first retaining plate 1212, thereby connecting the subseal 122 to the exterior trim panel 121. This allows the end of the subseal 122 to be fixed relative to the exterior trim panel 121, preventing the subseal 122 from separating from the exterior trim panel 121, thereby improving the reliability and durability of the B-pillar sealing structure 12.
