Description

Technical Field

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

[0002] As vehicle owners' expectations for vehicle appearance continue to rise, the number of vehicles equipped with frameless door systems is increasing. Consequently, the performance requirements for door sealing structures are also increasing. The material and structure of the corner section of the door opening seal, as an integral component of the door sealing structure, significantly influence its curvature radius. In related art, the curvature radius of the door opening sealing strip is relatively large at the corner, requiring the corresponding B-pillar sealing strip to be injection-molded to form a corner, resulting in a complex B-pillar sealing structure and poor durability.

[0049] 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.

[0050] Please also refer to Figure 1-Figure 3 , Figure 1 A schematic diagram of a vehicle 100 provided in some embodiments of the present application is provided. Figure 2 for Figure 1 A partial structural diagram of a vehicle 100 is shown. Figure 3 for Figure 2 A schematic diagram of a vehicle 100 is shown, partially concealing doors 20. Vehicle 100 includes a body 10 and multiple doors 20. A portion of body 10 encloses a cockpit. Body 10 includes side panel metal parts 11, a B-pillar sealing structure 12, door opening seals, and a roof beam seal 13. These form the side panel metal parts 11, B-pillar sealing structure 12, door opening seals, and roof beam seal 13, while the side panel metal parts 11 and door opening seals form the door opening seal.

[0051] The side panel 11 forms part of the cockpit bulkhead. The side panel 11 has a plurality of door openings 10a, which pass through the side panel 11 along the thickness direction and communicate with the cockpit. Figure 1-Figure 3 In the illustrated embodiment, the vehicle 100 has two door openings 10a on one side, including a first door opening 10a1 and a second door opening 10a2. The first door opening 10a1 is the front door opening of the vehicle 100, and the second door opening 10a2 is the rear door opening 10a of the vehicle 100. Specifically, the side panel 11 includes a connected B-pillar 111 and a top beam 112. The B-pillar 111 is located between the first door opening 10a1 and the second door opening 10a2, thereby separating the first door opening 10a1 and the second door opening 10a2.

[0052] Based on this, the vehicle door 20 is pivotally connected to the vehicle body 10 and corresponds one-to-one with the door opening 10a. When the vehicle door 20 is open, the user can enter and exit the cockpit through the corresponding door opening 10a. When the vehicle door 20 is closed, the vehicle door 20 can seal the corresponding door opening 10a to protect the cockpit and ensure the safety of the user and property. Specifically, the vehicle door 20 includes a door body 21 and a door glass 22. The door body 21 is pivotally connected to the side panel 11.

[0053] The top beam seal 13 is fixed to the top beam 112 and extends along the extension direction of the top beam 112. When the vehicle door 20 is in a closed state, the outer side surface of the door glass 22 presses the top beam seal 13 to achieve sealing.

[0054] The door opening seal includes a first door opening seal 14 and a second door opening seal 15. The first door opening seal 14 is connected to the edge of the side panel 11 facing the first door opening 10a1, and the second door opening seal 15 is connected to the edge of the side panel 11 facing the second door opening 10a2. The first door opening seal 14 includes a main section 14A and a corner section 14B. The main section 14A includes a first sealing section 141 and a second sealing section 142. The end of the first sealing section 141 forms one end of the main section 14A, and the end of the second sealing section 142 forms the other end of the main section 14A. The first sealing section 141 extends along a first direction, and the second sealing section 142 extends along a second direction, and the first and second directions intersect. The first direction is generally parallel to the length of the top beam 112, and the second direction is generally parallel to the length of the B-pillar 111.

[0055] Based on this, the corner section 14B is connected between the first sealing section 141 and the second sealing section 142 and is a plastic structural component. Specifically, a portion of the corner section 14B is connected to the edge of the top beam 112 facing the first door opening 10a1, and another portion is connected to the edge of the B-pillar 111 facing the first door opening 10a1. Specifically, the material of the corner section 14B may include one or more of EPDM (ethylene propylene diene monomer), PVC (polyvinyl chloride), silicone rubber, chloroprene rubber, thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), and the like.

[0056] In this way, by connecting the first door opening seal 14 to the edge of the side panel 11 facing the first door opening 10a1, when the vehicle door 20 is closed, the inner surface of the door body 21 and the door glass 22 facing the cockpit can squeeze the first door opening seal 14 to achieve sealing, thereby preventing moisture and dust outside the vehicle 100 from entering the interior of the vehicle.

[0057] On this basis, by connecting corner section 14B between the first sealing section 141 and the second sealing section 142 of the main body section 14A and by making corner section 14B a plastic structural component, corner section 14B does not include metal reinforcements and can be formed through injection molding. Therefore, compared to forming corner section 14B through extrusion and then bending and assembling it onto the side panel 11, the corner radius of injection-molded corner section 14B can be minimized and wrinkle-free. This helps maximize the area of ​​door opening 10a, facilitating user entry and exit, and facilitating overlap with interior trim, thereby improving the overlap tolerance between components.

[0058] The corner section 14B is injection molded and connected between the first sealing section 141 and the second sealing section 142 to form an integral structure with the main section 14A. This reduces the seam between the structure formed by the corner section 14B and the main section 14A, preventing the risk of delamination and cracking. In some examples, the main section 14A can be formed through an extrusion process, which provides a consistent cross-section, a smooth surface, high strength, and improved manufacturing efficiency. The corner section 14B can be formed through an injection molding process and connected between the first sealing section 141 and the second sealing section 142. This allows the corner section 14B to form a complex structure, which helps improve the overall reliability of the side panel sealing structure.

[0059] Please also refer to Figure 4-Figure 6 , Figure 4 for Figure 3 A partial structural diagram of the side panel 11 of the vehicle 100 is shown. Figure 5 for Figure 3 The schematic diagram of the partial structure of the first door opening seal 14 of the vehicle 100 is shown. Figure 6 for Figure 4 The following is a cross-sectional view of a portion of the vehicle 100 structure taken along line AA. The edge of the side panel 11 facing the first door opening 10a1 includes a first edge segment 11a. The corner segment 14B includes a first connecting portion 143 and a first sealing portion 144. The first sealing portion 144 is connected to the first connecting portion 143 and is located on one side of the first connecting portion 143 along the thickness direction of the side panel 11. Specifically, the first sealing portion 144 is located on the side of the first connecting portion 143 facing the exterior of the vehicle 100. The first connecting portion 143 has a first retaining groove 14a, into which the first edge segment 11a is inserted and fixed. One of the first edge segment 11a and the sidewall of the first retaining groove 14a has a first retaining groove 14a1, and the other has a first retaining protrusion 11a1. The first retaining protrusion 11a1 fits within the first retaining groove 14a1.

[0060] Figure 4-Figure 6 In the illustrated embodiment, the first limiting groove 14a1 is formed in the sidewall of the first engaging groove 14a, and the first limiting protrusion 11a1 is formed in the first edge section 11a of the side panel 11. In other embodiments, the first limiting groove 14a1 may also be formed in the first edge section 11a, and the first limiting protrusion 11a1 may be formed in the sidewall of the first engaging groove 14a.

[0061] In this way, when the first door opening seal 14 is assembled to the side panel sheet metal 11, the assembly can be started from the corner section 14B. The first limiting groove 14a1 and the first limiting protrusion 11a1 cooperate to limit the movement of the corner section 14B relative to the side panel sheet metal 11, which can improve the assembly efficiency and assembly accuracy, and thus ensure the matching quality of the first door opening seal 14 and the side panel sheet metal 11 and the interior decoration.

[0062] Please continue reading Figure 4-Figure 6 The first edge section 11a comprises a first section 11a2, a second section 11a3, and a third section 11a4, which are sequentially connected along the circumference of the first door opening 10a1. The second section 11a3 extends along an arcuate path, while the first and third sections 11a2 and 11a4 extend along straight paths. Therefore, the first limiting protrusion 11a1 is formed on the first section 11a2 and is perpendicular to the extension path of the first section 11a2. Figure 4-Figure 6 In the illustrated embodiment, the first section 11a2 forms a portion of the edge of the top beam 112 facing the first door opening 10a1, and the third section 11a4 forms a portion of the edge of the B-pillar 111 facing the first door opening 10a1. In other embodiments, the first section 11a2 may also form a portion of the edge of the B-pillar 111 facing the first door opening 10a1, and the third section 11a4 forms a portion of the edge of the top beam 112 facing the first door opening 10a1.

[0063] In this way, the difficulty of designing, manufacturing and assembling the first limiting protrusion 11a1 and the first limiting groove 14a1 can be reduced, and the first limiting protrusion 11a1 can be prevented from tilting relative to the extension path of the first section 11a2, so that when the first door opening seal 14 and the side panel sheet metal 11 are assembled, the two slide relative to each other, thereby increasing the difficulty of assembly.

[0064] Please continue reading Figure 4-Figure 6 The first limiting protrusion 11a1 is formed by a portion of the first edge segment 11a that is arched along the thickness direction of the first edge segment 11a. Specifically, the first limiting protrusion 11a1 can be formed on the first segment 11a2 through a process such as stamping. This creates a three-dimensional structure on the side panel 11 at the first edge segment 11a, enhancing the structural strength of the first edge segment 11a and ensuring the reliable positioning of the first limiting protrusion 11a1 and the first limiting groove 14a1. Furthermore, this saves material on the side panel 11 and the corner segment 14B, thereby reducing the overall cost and manufacturing difficulty of the vehicle 100.

[0065] In some other embodiments, the first limiting protrusion 11a1 may also be a boss structure formed by partially increasing the material thickness of the first section 11a2.

[0066] Please continue reading Figure 4-Figure 6The radius of curvature R of the edge of the second section 11a3 facing the first door opening 10a1 is less than or equal to 50 mm. For example, the radius of curvature R can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, etc. It should be noted that if the edge is arc-shaped, the radius of curvature R is the radius of the circle on which the arc is located. If the edge is non-arc-shaped, the radius of curvature R is the radius of curvature at the point on the edge where the radius of curvature is the smallest. This increases the area of ​​the first door opening 10a1, making it easier for users to enter and exit the cockpit.

[0067] Please continue reading Figure 4-Figure 6 The angle between the first section 11a2 and the third section 11a4 is less than or equal to 90°. That is, the first door opening 10a1 is the front door opening 10a of the vehicle 100. In this way, increasing the area of ​​the first door opening 10a1 makes it easier for users to enter and exit the cockpit.

[0068] Please also refer to Figure 7 and Figure 8 , Figure 7 for Figure 2 The cross-sectional view of the vehicle 100 is shown along line BB. Figure 8 for Figure 2 A cross-sectional view of a portion of the vehicle 100 is shown along line CC. The aforementioned first connecting portion 143 comprises a first connecting segment 1431 and a second connecting segment 1432, which are connected along the circumference of the first door opening 10a1. The first connecting segment 1431 extends along a straight path, while the second connecting segment 1432 extends along an arcuate path. The first sealing portion 1444 comprises a first portion 1441 and a second portion 1442, which are connected along the circumference of the first door opening 10a1. The first portion 1441 connects to the first connecting segment 1431 and encloses a first cavity 14B1. The second portion 1442 connects to the second connecting segment 1432 and encloses a second cavity 14B2. The cross-sectional area of ​​the first cavity 14B1 is larger than that of the second cavity 14B2. Accordingly, the first connecting segment 1431 connects to the aforementioned third segment 11a4, and the second connecting segment 1432 connects to the aforementioned second segment 11a3. In some other embodiments, the first connecting segment 1431 may also be connected to the aforementioned first segment 11a2.

[0069] In this way, the volume of the second cavity 14B2 in the corner area corresponding to the second part 1442 is smaller. When the vehicle door 20 is closed and squeezes the second part 1442, the deformation of the second part 1442 can be smaller, which can prevent the second part 1442 from collapsing and causing a decrease in sealing reliability.

[0070] For details, please refer to Figure 7 and Figure 8The first connecting portion 143 includes a first connecting wall 143a, a second connecting wall 143b, and a third connecting wall 143c. The first connecting wall 143a is spaced apart from the third connecting wall 143c, and the second connecting wall 143b is connected between the first connecting wall 143a and the third connecting wall 143c. The first connecting wall 143a, the second connecting wall 143b, and the third connecting wall 143c enclose the aforementioned first clamping groove 14a, and the aforementioned first limiting groove 14a1 is formed in the first connecting wall 143a. The first sealing portion 144 includes a sealing portion 144a and a supporting portion 144b. The two ends of the sealing portion 144a are respectively connected to one end of the first connecting wall 143a and one end of the supporting portion 144b. The supporting portion 144b is located on the side of the sealing portion 144a away from the first door opening 10a1, and the other end of the supporting portion 144b is connected to the other end of the first connecting wall 143a. The sealing portion 144a and the supporting portion 144b are both arched toward the inner side of the first door opening 10a1, wherein the surface of the supporting portion 144b facing away from the first door opening 10a1 forms the first outer side surface 14B4 of the corner section 14B.

[0071] Please continue reading Figure 7 and Figure 8 A portion of the first connecting wall 143a arches toward the second cavity 14B2 along the thickness of the side panel 11, thereby forming a third cavity 14B3 with a portion of the first edge segment 11a. In other words, the portion of the first connecting wall 143a corresponding to the second connecting segment 1432 and the second segment 11a3 of the first edge segment 11a enclose the third cavity 14B3.

[0072] As a result, when the vehicle door 20 is closed, the second portion 1442 of the first sealing portion 144 is deformed by force, and the first connecting wall 143a can act as an elastic support, thereby preventing the corner section 14B from collapsing and preventing difficulty in fitting the door glass 22 into the groove, thereby ensuring the overall reliability of the vehicle 100. Furthermore, the structure of the third cavity 14B3 facilitates demolding after the corner section 14B is formed by injection molding.

[0073] Please continue reading Figure 8 The angle α formed by the arching of a portion of the first connecting wall 143a toward the second cavity 14B2 is greater than or equal to 80° and less than or equal to 120°. For example, the angle α can be 80°, 85°, 90°, 100°, 110°, 120°, etc. This prevents the angle α from being too small, which would make it difficult for the first connecting wall 143a to deform and thus hinder the glass of the door 20 from fitting into the groove. It also prevents the angle α from being too large, which would make the first connecting wall 143a susceptible to significant deformation under stress and thus easily collapse the corner portion of the corner section 14B.

[0074] Based on the above, please refer to Figure 9 , Figure 9 for Figure 2 The figure shows a cross-sectional view of a portion of the vehicle 100 structure at line DD. The main body section 14A includes a second connecting portion 14A1, a second sealing portion 14A2, and a reinforcement 14A3. The second connecting portion 14A1 is connected to the edge of the side panel 11 facing the first door opening 10a1. The second sealing portion 14A2 is connected to the second connecting portion 14A1 and is located on one side of the second connecting portion 14A1 along the thickness direction of the side panel 11. Specifically, the second sealing portion 14A2 is located on the side of the second connecting portion 14A1 facing the outside of the vehicle. The reinforcement 14A3 is embedded in the second connecting portion 14A1. The two ends of the reinforcement 14A3 are located on both sides of the side panel 11 along the thickness direction of the side panel 11. The strength of the reinforcement 14A3 is greater than that of the second connecting portion 14A1. Specifically, the reinforcement 14A3 can be a U-shaped metal sheet. The specific structure of the main body segment 14A can refer to the structure of the first connecting segment 1431 of the aforementioned corner segment 14B and the first part 1441 of the first sealing portion 144, which will not be repeated here.

[0075] In this way, the structural strength of the second connecting portion 14A1 of the main body section 14A can be improved, ensuring the reliability of the connection between the main body section 14A and the side panel 11, thereby ensuring the reliability of the side panel sealing structure and the vehicle 100.

[0076] The structure of the second door opening seal 15 and the connection structure between it and the side panel sheet metal 11 can refer to the structure of the first door opening seal 14 and the connection structure between it and the side panel sheet metal 11, and will not be repeated here.

[0077] Please also refer to Figure 2 、 Figure 10 and Figure 11 , Figure 10 for Figure 2 The structural diagram of the B-pillar sealing structure 12 of the vehicle 100 is shown. Figure 11 for Figure 10An exploded view of the B-pillar sealing structure 12 is shown. The B-pillar sealing structure 12 includes an outer trim panel 121, two first seals 122, and a second seal 123. The outer trim panel 121 includes a first end 121A and a second end 121B, which are aligned along the length of the outer trim panel 121. The first end 121A has a first surface area 121a and a second surface area 121b, which are aligned along the thickness of the outer trim panel 121. Part of the edge of the first surface area 121a forms the outer edge of the outer trim panel 121. The length of the outer trim panel 121 is generally parallel to the length of the B-pillar 111, 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.

[0078] Please also refer to Figure 10-13 , Figure 12 for Figure 2 The structural diagram of the B-pillar sealing structure 12 of the vehicle 100 is shown as seen from another perspective. Figure 13 for Figure 12 An exploded view of the B-pillar sealing structure 12 is shown. Two first sealing members 122 are connected to the ends of the exterior panel 121 along its width and extend along its length. The first sealing member 122 includes a third sealing portion 1221, at least a portion of which is located on the outer periphery of the exterior panel 121. The two first sealing members 122 can be separate components or connected via a connecting structure to form a single, integrated structure.

[0079] The second sealing member 123 includes a third connecting portion 1231 and a fourth sealing portion 1232. The third connecting portion 1231 is located on the side opposite the first surface area 121a and is connected to the first end 121A. The fourth sealing portion 1232 has two ends connected to the ends of the two first sealing members 122, respectively. The fourth sealing portion 1232 extends around the first end 121A, with at least a portion located on the outer periphery of the first end 121A.

[0080] Specifically, the first seal 122 and the second seal 123 are integrally formed. This reduces the joints between the first and second seals 122, 123, preventing the risk of delamination and cracking, thereby improving the overall sealing and durability of the B-pillar sealing structure 12. In some examples, the first seal 122 can be formed through an extrusion process, resulting in 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 first seal 122 by injection molding. This allows the second seal 123 to form a complex structure that adapts and connects to the aforementioned first end 121A, thereby improving the overall reliability of the B-pillar sealing structure 12.

[0081] In this way, the B-pillar sealing structure 12 provided in the present application is such that the two first sealing members 122 are connected to the two ends of the outer trim panel 121 along the width direction of the outer trim panel 121, and at least a portion of the third 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 third sealing portion 1221; and the fourth sealing portion 1232 of the second sealing member 123 is extended around the first end 121A, and at least a portion of the fourth 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 is in contact with the first surface area 121a and is fitted and sealed with the fourth 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.

[0082] On this basis, by positioning the third connection portion 1231 of the second seal 123 on the side opposite to 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 durability of the B-pillar sealing structure 12 is improved, further enhancing the overall aesthetics and reliability of the vehicle 100.

[0083] Please also refer to Figure 9 、 Figure 12-14 , Figure 14 for Figure 2A cross-sectional view of a portion of the structure of the vehicle 100 is shown at line EE. The first sealing member 122 also includes a fourth connecting portion 1222, which is connected to the third sealing portion 1221. Specifically, the fourth connecting portion 1222 extends along the length of the exterior panel 121 and is located on the side of the corresponding third sealing portion 1221 close to the other third 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 arranged to form a first mounting groove 121c. The opening of the first mounting groove 121c faces the outer peripheral side of the exterior panel body 1211.

[0084] Specifically, the first limiting plate 1212 can extend from the end connected to the outer panel body 1211, first along the thickness direction of the outer panel body 1211, away from the outer panel body 1211, and then along the width direction of the outer panel body 1211, toward the outer periphery of the outer panel body 1211. On this basis, the fourth connecting portion 1222 of the first sealing member 122 is fixedly engaged within the first mounting groove 121c. Specifically, the fourth 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.

[0085] On this basis, the third 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 fourth connecting portion 1222, the sealing end is suspended and has an arc shape, and the center of curvature of this 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 fourth 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 third sealing portion 1221 is located on the outer periphery of the exterior trim panel 121.

[0086] The side of second sealing lip 1221b facing first door opening 10a1 forms second outer side 122a of first sealing member 122. Second outer side 122a faces first outer side 14B4. When vehicle door 20 is closed, the outer side of the edge of door glass 22 presses against first sealing lip 1221a to achieve a seal, while the inner side of the edge of door glass 22 presses against second sealing lip 1221b to achieve a seal.

[0087] In this way, the outer panel 121 has a better structural strength and is more resistant to the impact force generated by closing the vehicle door 20. In addition, the connection area between the fourth connecting portion 1222 and the outer panel 121 is larger, which can improve the connection reliability between the two.

[0088] In some other embodiments, the exterior panel 121 may not include the first limiting plate 1212 , and the fourth connecting portion 1222 may be connected to the exterior panel body 1211 .

[0089] Please also refer to Figure 10-13 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 fourth sealing portion 1232 extends along first edge segment 121a1 and connects to second surface region 121b. Third connecting portion 1231 connects to this portion of fourth sealing portion 1232.

[0090] As a result, a portion of the fourth sealing portion 1232 is located on the outer periphery of the exterior panel 121. When the vehicle door 20 is closed, the door body 21 compresses a portion of the fourth 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 fourth sealing portion 1232 is located between the exterior panel 121 and the B-pillar 111. This not only provides a connection framework for the third connecting portion 1231 but also cushions the exterior panel 121, preventing damage caused by hard contact between the exterior panel 121 and the B-pillar 111 due to the impact of closing the vehicle door 20.

[0091] Please continue reading Figure 10-13The fourth sealing portion 1232 includes two fourth sealing segments 1232a and a third sealing segment 1232b. One end of the third sealing segment 1232b is connected to the end of one first sealing component 122 via the fourth sealing segment 1232a, and the other end of the third sealing segment 1232b is connected to the end of another first sealing component 122 via another fourth sealing segment 1232a. The fourth 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.

[0092] In this way, the sealing structures corresponding to the corners of the exterior panel 121 are all formed in the second seal 123, so that the connection between the first seal 122 and the second seal 123 avoids the corners, which simplifies the design, production and connection difficulty of the first seal 122 and the second seal 123, and also enables the connection reliability between the first seal 122 and the second seal 123 to be better.

[0093] Figure 10 and Figure 13 In the illustrated embodiment, the first mounting groove 121c is located on the side of the fourth sealing segment 1232a away from the third sealing segment 1232b. The fourth sealing segment 1232a is in contact with the outer surface of the exterior panel body 1211. In other embodiments, the structure of the fourth sealing segment 1232a can also be similar to that of the first sealing member 122, with a portion of the fourth sealing segment 1232a snapping into the first mounting groove 121c. Furthermore, the third sealing segment 1232b forms a fifth sealing lip, the ends of which, along their extension, respectively connect with the ends of the fourth sealing lips 1232a2 of the two fourth sealing segments 1232a. The structure of the fifth sealing lip can be similar to that of the fourth sealing lips 1232a2 and will not be further described here. In other embodiments, the fourth sealing portion 1232 may not include the two fourth sealing segments 1232a, with the ends of the third sealing segment 1232b directly connecting with the ends of the two first sealing members 122 at the corners of the exterior panel 121.

[0094] Please also refer to Figure 11 、 Figure 13 and Figure 14The 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 to the first surface area 121a. The surface of the flange 1213 opposite to the first surface area 121a forms a portion of the second surface area 121b and is attached to at least a portion of the fourth sealing portion 1232. Specifically, the flange 1213 is attached to the third sealing segment 1232b of the fourth sealing portion 1232. It should be noted that when the fourth sealing portion 1232 does not include the fourth sealing segment 1232a, the flange 1213 is attached to the entire fourth sealing portion 1232. That is, a portion of the exterior panel body 1211 forms a portion of the first end 121A, and the flange 1213 forms another portion of the first end 121A.

[0095] This allows for a thinner outer panel 121 and third 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 third connecting portion 1231 and the outer panel 121.

[0096] Please also refer to Figure 11-13 The third connecting portion 1231 includes a third connecting segment 1231a and a fourth connecting segment 1231b. The third connecting segment 1231a extends generally parallel to the width of the exterior panel 121, and its ends are connected to the ends of the third sealing segment 1232b. The fourth connecting segment 1231b extends generally parallel to the length of the exterior panel 121 and is located within the space enclosed by the third connecting segment 1231a and the third sealing segment 1232b. The fourth connecting segment 1231b connects to both the third connecting segment 1231a and the third sealing segment 1232b. In other embodiments, the third connecting segment 1231a may extend in a direction that intersects with, and is not perpendicular to, the width of the exterior panel 121; and the fourth connecting segment 1231b may extend in a direction that intersects with, and is not perpendicular to, the length of the exterior panel 121.

[0097] As a result, the third connecting segment 1231a and the fourth connecting segment 1231b can form a three-dimensional structure with the third sealing segment 1232b, thereby improving the overall structural strength of the second sealing member 123. Furthermore, the third connecting segment 1231a and the fourth connecting segment 1231b cooperate with the 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 first and second sealing members 122, 123 from separating from the outer trim panel 121, which would otherwise result in poor reliability and durability of the overall B-pillar sealing structure 12.

[0098] Please continue reading Figure 11-13 The fourth connecting segment 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 second limiting protrusion 121d. The second limiting protrusion 121d is accommodated in the first limiting hole 1231c. Specifically, the second 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 third connecting segment 1231a. In this way, when the first and second sealing members 122, 123 are assembled to the exterior panel 121, the cooperation between the first limiting hole 1231c and the second 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.

[0099] Please continue reading Figure 11-13 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 third 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 third sealing segment 1232b of the second sealing member 123.

[0100] 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.

[0101] Please continue reading Figure 11-13 The first engaging structure 121e includes a engaging protrusion, and the second engaging structure 1231d includes a engaging ring. The axis of the engaging ring is generally parallel to the thickness of the exterior panel 121. The engaging protrusion fits within the engaging ring. Specifically, the cross-sectional shape of the engaging protrusion can be circular, triangular, quadrilateral, pentagonal, etc. Furthermore, the engaging protrusion can be provided with a staple, which allows the exterior panel 121 to be attached to the B-pillar 111.

[0102] As a result, the structures of the first and second clamping structures 121e, 1231d are relatively simple, facilitating the design, manufacture, and assembly of the exterior panel 121 and the second seal 123. Furthermore, the mating surface between the first and second clamping structures 121e, 1231d is relatively large, resulting in greater reliability in the clamping connection between the first and second clamping structures 121e, 1231d.

[0103] 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.

[0104] Please continue reading Figure 11-13 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 fourth 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 fourth 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 third sealing section 1232b are located on both sides of the fourth connecting section 1231b. The number of first clip structures 121e and second clip structures 1231d can be 2, 3, 4, etc.

[0105] 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.

[0106] Please also refer to Figure 12 and Figure 15 , Figure 15 for Figure 12 The B-pillar sealing structure 12 is shown in a cross-sectional view at line FF. The end face of the first seal 122 away from the second seal 123 is flush with the end face of the second end 121B of the exterior panel 121. The first outer side surface 14B4 of the aforementioned corner section 14B, which faces the top beam 112, is flush with the second outer side surface 122a of the first seal 122, which faces the top beam 112. Based on this, the B-pillar sealing structure 12 also includes a connector 124, through which the end of the first seal 122 is connected to the second end 121B of the exterior panel 121. Specifically, the connector 124 can be a staple. The fourth connecting portion 1222 of the first seal 122 and the first limiting plate 1212 of the exterior panel 121 can both be provided with connecting holes. The staple is inserted through the connecting hole to connect the fourth connecting portion 1222 to the first limiting plate 1212, thereby connecting the first seal 122 to the exterior panel 121.

[0107] This eliminates the need for an additional injection-molded joint at the end of the first seal 122 facing the roof beam 112, improving the overall aesthetics, assembly efficiency, and durability of the vehicle 100 and reducing the cost of the vehicle 100. Furthermore, the end of the first seal 122 can be fixed relative to the exterior trim panel 121, preventing separation between the first seal 122 and the exterior trim panel 121, thereby improving the reliability and durability of the B-pillar sealing structure 12.

[0108] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
