[0036] As Figure 1As shown in the figure, the utility model provides a B-pillar cover plate sealing structure, which includes a cover plate assembly, an adhesive member 7 and a sealing member 1. The cover plate assembly is connected to the B-pillar sheet metal 8 of the vehicle to form a receiving cavity. The sealing member 1 is located in the receiving cavity, and the volume of the sealing member 1 is larger than the volume of the receiving cavity. The adhesive member 7 is located between the sealing member 1 and the cover plate assembly to bond the sealing member 1 and the cover plate assembly. The sealing member 1 at least forms a first sealing surface 101 and a second sealing surface 102, and the first sealing surface 101 is attached to the cover plate assembly, and the second sealing surface 102 is attached to the B-pillar sheet metal 8.

[0037] For the B-pillar cover plate sealing structure provided by the utility model, by arranging the sealing member 1 in the receiving cavity formed between the B-pillar sheet metal 8 and the cover plate assembly, and at least the first sealing surface 101 and the second sealing surface 102 are formed on the sealing member 1 in this application, so that the tight fit between the sealing member 1 and the cover plate assembly can be ensured through the first sealing surface 101, thereby ensuring the sealing degree, and the tight fit between the sealing member 1 and the B-pillar sheet metal 8 can be ensured through the second sealing surface 102, and then the sealed connection between the sealing member 1 and the B-pillar sheet metal 8 and the cover plate assembly is realized.

[0038] Moreover, since the volume of the sealing member 1 in this application is larger than the volume of the receiving cavity, when the sealing member 1 is assembled into the receiving cavity, the sealing member 1 and the cover plate assembly, the B-pillar sheet metal 8 and other nearby related structures are all in interference fit, that is, the sealing member 1 can be in close contact with the B-pillar sheet metal 8, the cover plate assembly and other surrounding related structural parts, so as to ensure the sealing degree and the sound absorption and sound insulation effect, and improve the user experience.

[0039] Preferably, the sealing member 1 in this application is made of PE foam. PE foam not only has a certain plasticity to achieve the above-mentioned interference fit, but also has a porous structure and has a certain degree of sound absorption effect. Furthermore, the sealing member 1 not only has the functions of sealing, waterproofing and dustproofing, but also can reduce the propagation of noise to a certain extent and improve the sound insulation effect of the passenger cabin.

[0040] Optionally, as Figures 2 - 4 shown, the cover plate assembly includes an inner cover plate 2 and an outer cover plate 3. The outer cover plate 3 is arranged on the outer side of the inner cover plate 2 and is connected to the inner cover plate 2. The side of the inner cover plate 2 facing away from the outer cover plate 3 is attached to the first sealing surface 101.

[0041] A decorative surface is formed on the side of the outer cover plate 3 facing away from the inner cover plate 2, so as to be able to decorate the corresponding external position of the vehicle B-pillar and make the vehicle exterior more beautiful. And the further arranged inner cover plate 2 can provide a basis for the connection of the outer cover plate 3.

[0042] Optionally, as Figure 2 Combined with Figure 4As shown, the cover plate assembly in the present application further includes a decorative member 4. The decorative member 4 is snap-connected to the B-pillar sheet metal 8, and the decorative member 4 is formed with an extension portion 401. The sealing member 1 is formed with a third sealing surface 103, and the third sealing surface 103 is attached to the extension portion 401; a limiting portion 301 is formed at a position where the outer cover plate 3 is close to the decorative member 4, and a supporting portion 202 is formed at a position where the inner cover plate 2 is close to the limiting portion 301. The end of the decorative member 4 abuts against the limiting portion 301, and a limiting space is formed between the limiting portion 301 and the decorative member 4. A mating portion is formed at a position of the sealing member 1 corresponding to the limiting space; an avoidance portion is formed at a position of the sealing member 1 corresponding to the supporting portion 202, and the supporting portion 202 passes through the avoidance portion and abuts against the B-pillar sheet metal 8.

[0043] The decorative member 4 in the present application is an exterior decorative bright strip for a vehicle. The formed extension portion 401 can, on the one hand, make the connection of the decorative member 4 more stable. On the other hand, by cooperating with the third sealing surface 103 formed by the extension portion 401 and the sealing member 1, a more airtight sealing structure can be obtained, thereby improving the sealing degree of the overall structure and ensuring the waterproof, dustproof and sound insulation effects.

[0044] The limiting portion 301 formed by the outer cover plate 3 can cooperate with the decorative member 4 to form a limiting space, and thus, through the mating portion formed by the sealing member 1, the limiting effect on the sealing member 1 can be realized. And as Figure 2 shown, the supporting portion 202 formed at a position where the inner cover plate 2 is close to the limiting portion 301 can support the B-pillar sheet metal 8, preventing the B-pillar sheet metal 8 from being deformed and dented due to collision during manufacturing or use, which affects the limiting of the sealing member 1 and the sealing and sound insulation effects of the sealing member 1 itself.

[0045] Optionally, as Figure 1 combined with Figure 2 and Figure 4 shown, hooks 201 are provided on a surface of the inner cover plate 2 facing the sealing member 1. A clamping groove is formed at a position of the B-pillar sheet metal 8 corresponding to the hooks 201. The hooks 201 are connected to the clamping groove, so that the inner cover plate 2 is connected to the B-pillar sheet metal 8; an avoidance hole 105 is formed at a position of the sealing member 1 corresponding to the hooks 201, and the hooks 201 pass through the avoidance hole 105 and are connected to the B-pillar sheet metal 8.

[0046] Through the cooperation of the hooks 201 and the clamping groove, the rapid positioning and connection of the inner cover plate 2 and the B-pillar sheet metal 8 can be realized, thereby improving the assembly efficiency. Correspondingly, since the sealing member 1 in the present application is located between the inner cover plate 2 and the B-pillar sheet metal 8, therefore, through the avoidance hole 105 formed by the sealing member 1, the hooks 201 can pass through the sealing member 1 and be hooked to the clamping groove, avoiding assembly interference.

[0047] Optionally, as Figure 2As shown, the B-pillar cover structure provided by the present utility model further includes an upper strip assembly 5. Both ends of the upper strip assembly 5 are respectively connected to the decorative member 4 and the B-pillar sheet metal 8, and are located at the top of the accommodation cavity to seal the top of the accommodation cavity.

[0048] Through the upper strip assembly 5, the top position of the accommodation cavity formed by the B-pillar sheet metal 8 and the cover assembly can be sealed, so that the accommodation cavity can form a relatively airtight space, improving the corresponding sealing performance of the overall structure and ensuring the waterproof, dustproof and sound insulation effects.

[0049] Optionally, as Figure 2 Combined Figure 4 As shown, the upper strip assembly 5 in the present application includes a main body member 501 and a positioning member 502. The main body member 501 is connected to the decorative member 4 and the B-pillar sheet metal 8, and positioning through holes are formed on the main body member 501. The positioning member 502 passes through the positioning through holes to press the main body member 501 against the B-pillar sheet metal 8.

[0050] In the present application, the main body member 501 is located between the inner cover 2 and the top of the B-pillar sheet metal 8, and is actually connected such that one end of the main body member 501 is connected to the decorative member 4 and the other end is connected to the B-pillar sheet metal 8. Since the decorative member 4 and the cover assembly are hermetically connected through the sealing member 1 in the present application, therefore, the main body member 501, the decorative member 4, the cover assembly and the B-pillar sheet metal 8 together form a relatively airtight accommodation cavity, and cooperate with the sealing member 1 to achieve the sealing of the overall structure.

[0051] It should be supplemented and explained here that the B-pillar sheet metal 8 in the present application also forms alignment holes corresponding to the positioning through holes, so that the positioning member 502 can pass through the positioning through holes and the alignment holes to realize the positioning of the main body member 501.

[0052] To ensure the stable connection between the main body member 501 and the B-pillar sheet metal 8, in the present application, through the positioning member 502, the main body member 501 can be pressed and positioned on the B-pillar sheet metal 8 to ensure the stable connection between the two.

[0053] It can be understood that, as Figure 4 As shown, since positioning through holes are formed at the positions of the main body member 501 corresponding to the positioning member 502 in the present application, therefore, by forming an avoidance groove 106 at the position of the sealing member 1 corresponding to the positioning through holes in the present application, one end of the positioning member 502 passing through the positioning through holes can be accommodated, so as to avoid the problem that the positioning member 502 cannot be tightly assembled or cannot be assembled in place due to the interference of the sealing member 1 with the assembly of the positioning member 502.

[0054] Optionally, as Figure 3As shown, a fourth sealing surface 104 is further formed on the sealing member 1 in the present application, and the fourth sealing surface 104 is attached to the window glass guide rail 6 of the vehicle.

[0055] In addition, the present utility model further provides a vehicle, including the B-pillar cover plate sealing structure described above.

[0056] For a vehicle adopting the B-pillar cover plate sealing structure provided by the present application, the waterproof and dustproof effects can be ensured at the B-pillar position. At the same time, it has a high sound insulation effect, thereby improving the use experience and driving and riding feelings of vehicle users.

[0057] It can be understood that when assembling the B-pillar cover plate sealing structure provided by the present application, first, the sealing member 1 is combined with the cover plate assembly through the adhesive 7. After that, the cover plate assembly with the sealing member 1 is assembled onto the B-pillar sheet metal 8 uniformly. Finally, the window glass guide rail 6 is assembled to complete the installation of the cover plate assembly and the sealing member 1 at the B-pillar.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
