Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a frameless vehicle window B-pillar sealing structure and a vehicle. Background Art

[0002] Frameless windows are becoming more and more popular in the market due to their sporty appearance. Since there is no window frame sheet metal, the design of the B-pillar of the vehicle body is particularly important in terms of function and appearance. Among them, the B-pillar glass sealing strip, as an important component of the sealing structure of frameless windows, is mainly composed of the front B-pillar extrusion section, the rear B-pillar extrusion section, the front B-pillar upper corner, the rear B-pillar upper corner, and the lower corner. Its main function is to seal with the door glass through the inner and outer lip structures, and at the same time overlap with the door frame sealing strip to prevent rain and wind and sand from entering the cab.

[0003] The extrusion section of the existing B-pillar sealing strip is usually lower in height than the upper edge of the door glass, and the upper corner portion is integrally clamped on the upper edge of the door glass and connected to the top of the extrusion section. When the door glass is closed, the upper corner is used to form an interference seal with the door frame sealing strip. The disadvantage of this sealing structure is that when the door glass rises, the upper corner is easily squeezed and deformed, which makes it difficult for the door glass to enter the groove and the sealing is not tight. In addition, since the joint between the extrusion section and the upper corner is leaking, the exquisite appearance of the upper area of ​​the B-pillar is affected. Utility Model Content

[0004] The embodiment of the utility model provides a sealing structure for a frameless vehicle window B-pillar, which is intended to improve the sealing reliability between the vehicle door glass and the B-pillar and the refined appearance of the upper portion of the B-pillar.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: in the first aspect, a frameless window B-pillar sealing structure is provided, including a door frame sealing strip and a glass sealing strip arranged on the B-pillar trim; the glass sealing strip includes two extruded sections and two corner portions, the two extruded sections are respectively arranged at the front and rear boundaries of the B-pillar trim, the two corner portions are connected to the top of the B-pillar trim, and are respectively located on the front and rear sides of the B-pillar trim; the extruded section has an inner lip and an outer lip that are respectively pressed against the inner and outer surfaces of the door glass; wherein the outer lip extends to the upper boundary of the door glass and interferes with the door frame sealing strip for sealing, the top end of the inner lip is lower than the upper boundary of the door glass, the corner portion is connected to the inner lip up and down, and interferes with the door frame sealing strip for sealing.

[0007] In some embodiments, the first sealing lip has a first Y-direction interference amount with the inner surface of the door glass, the second sealing lip has a second Y-direction interference amount with the inner surface of the door glass, and the second Y-direction interference amount is smaller than the first Y-direction interference amount.

[0008] Exemplarily, the sealing structure of the frameless window B-pillar also includes a door sealing strip, which cooperates with a boundary gap of the corner portion away from the B-pillar trim.

[0009] For example, the corner portion is provided with a third sealing lip away from the boundary of the B-pillar trim. When the door glass is opened, a buffer gap is provided between the third sealing lip and the door sealing strip. When the door glass is closed, the third sealing lip contacts the door sealing strip.

[0010] In combination with the first aspect, in a possible implementation, the front and rear boundaries of the B-pillar trim are both provided with embedding grooves, and the side of the extruded section facing away from the door glass has a mounting strip, which is embedded in the embedding groove.

[0011] In some embodiments, a clamping groove is provided on one side groove wall of the embedding groove, and a clamping rib is provided on the mounting strip. The clamping rib extends obliquely toward the mouth of the embedding groove and is clamped with the clamping groove.

[0012] Exemplarily, a limiting rib is provided on a side of the mounting strip facing away from the clamping rib, and the limiting rib abuts against a groove wall of the embedding groove facing away from the clamping groove.

[0013] For example, mesh ribs are provided at positions corresponding to the two corner portions of the B-pillar trim, and the mesh ribs are used to support the corner portions.

[0014] The beneficial effect of the frameless vehicle window B-pillar sealing structure provided by the utility model is that: compared with the prior art, in the frameless vehicle window B-pillar sealing structure of the utility model, the glass sealing strip is respectively pressed against the inner and outer surfaces of the vehicle door glass through the inner lip edge and the outer lip edge on the extrusion section to form a seal on the side edge of the vehicle door glass, and at the same time, two corner portions located on the inner side of the vehicle door glass are respectively used to form an interference seal with the door frame sealing strips on the front and rear sides of the B-pillar, thereby realizing the sealing of the vehicle door glass at the top corner position of the B-pillar; on this basis, the outer lip edge of the glass sealing strip is directly extended to the upper boundary of the vehicle door glass, thereby preventing the joint position of the glass sealing strip and the corner portion from being exposed, thereby improving the exquisite appearance of the B-pillar trim panel; the outer lip edge is directly used to interfere with the door frame sealing strip to seal, thereby avoiding the problem of deformation of the corner portion caused by the outer lip edge pressing the corner portion upward when the vehicle door glass is raised, which not only facilitates the vehicle door glass to enter the groove, but also improves the sealing reliability of the corner portion between the vehicle door glass and the top area of ​​the B-pillar.

[0025] Please also read Figures 1 to 5The frameless vehicle window B-pillar sealing structure provided by the utility model is now described. The frameless vehicle window B-pillar sealing structure comprises a door frame sealing strip 10 and a glass sealing strip 30 arranged on the B-pillar trim 20; the glass sealing strip 30 comprises two extrusion sections 31 and two corner portions 32, the two extrusion sections 31 are respectively arranged at the front and rear boundaries of the B-pillar trim 20, the two corner portions 32 are both connected to the top of the B-pillar trim 20, and are respectively located at the front and rear sides of the B-pillar trim 20; the extrusion section 31 has an inner lip 311 and an outer lip 312 respectively pressed against the inner and outer surfaces of the vehicle door glass 40; wherein the outer lip 312 extends to the upper boundary of the vehicle door glass 40 and interferes with the door frame sealing strip 10 for sealing, the top end of the inner lip 311 is lower than the upper boundary of the vehicle door glass 40, the corner portion 32 is connected to the inner lip 311 up and down, and interferes with the door frame sealing strip 10 for sealing.

[0026] It should be noted that, in this embodiment, the door frame sealing strip 10 is a sealing strip fixed to the lower edge of the door frame at the top of the door opening (i.e., the top edge beam of the side panel of the vehicle body). The specific connection method can be to clamp the door frame sealing strip 10 on the decorative strip at the lower edge of the door frame, and then fix the decorative strip to the top edge beam of the side panel by fasteners such as screws.

[0027] The above-mentioned extrusion section 31 can be specifically understood as a uniform cross-section sealing strip integrally formed by a rubber extrusion process, and the corner portion 32 is located in the corner area formed by the top end of the B-pillar and the top edge beam of the side panel. Therefore, the corner portion 32 can be configured as a triangle or a triangle-like structure. Here, the corner portion 32 can be specifically a triangle-like structure formed by three edges connected in sequence, one of which extends along the boundary of the B-pillar trim 20, another edge extends along the door frame sealing strip 10, and the third edge is connected to the first two edges in an arc-shaped extension manner; in fact, the edge of the corner portion 32 extending along the boundary of the B-pillar trim 20 has the same effect as the inner lip edge 311 of the extrusion section 31, and the arc-shaped extending edge contacts the inner surface of the door glass 40 to form a second seal, and also plays a role in guiding the door glass 40 to enter the groove smoothly (here, entering the groove refers to the upper boundary of the door glass 40 entering the sealing groove of the door frame sealing strip 10).

[0028] It needs to be explained that Figure 4As shown, the extrusion section 31 in this embodiment is actually two sections respectively arranged at the front and rear boundaries of the B-pillar trim 20, each section extends to the upper boundary of the door glass 40, and then the other parts except the outer lip 312 at the top of the extrusion section 31 are cut and shortened, specifically, the shortening can be about 10 mm, and then the inner lip 311 is further shortened, thereby forming a space for installing the corner portion 32, and one side edge of the corner portion 32 is aligned with the inner lip 311 retained by the extrusion section 31 and connected to the inner lip 311, and the top of the corner portion 32 is flush with the upper boundary of the door glass 40, thereby forming a structure in which the outer lip 312 and the corner portion 32 interfere with the door frame sealing strip 10 for sealing, which can avoid the corner portion 32 from having a seam on the outside of the B-pillar trim 20 on the one hand, and can avoid the outer lip 312 squeezing the corner portion 32 when the door glass 40 is raised to cause deformation and affect the sealing reliability.

[0029] In this embodiment, the inner lip 311 forms a Y-direction interference with the inner surface of the door glass 40, so that the inner lip 311 forms a Y-direction compression of 2mm to 3mm under the pressure of the door glass 40, thereby ensuring the sealing effect; the outer lip 312 forms a Y-direction interference extrusion with the outer surface of the door glass 40, and the outer lip 312 is compressed and deformed in the direction away from the B-pillar trim 20, that is, in the X-direction, under the pressure of the door glass 40. Specifically, the X-direction compression deformation of the outer lip 312 can be designed to be 3mm to 4mm.

[0030] Furthermore, in this embodiment, the lower ends of the two extrusion segments 31 can be connected through a lower corner 33, and the lower corner 33 is connected to the lower end of the B-pillar trim 20. The lower ends of the two extrusion segments 31 are connected as a whole through the lower corner 33, thereby improving the overall connection reliability between the glass sealing strip 30 and the B-pillar trim 20 and preventing the lower ends of the two extrusion segments 31 from falling off the B-pillar trim 20.

[0031] Compared with the prior art, the frameless window B-pillar sealing structure provided in this embodiment has an inner lip edge 311 and an outer lip edge 312 on the extrusion section 31 of the glass sealing strip 30 respectively pressed against the inner and outer surfaces of the door glass 40 to form a seal on the side of the door glass 40, and at the same time, the two corner portions 32 located on the inner side of the door glass 40 respectively form an interference seal with the door frame sealing strip 10 on the front and rear sides of the B-pillar, thereby achieving the sealing of the door glass 40 at the top corner of the B-pillar; on this basis, the outer lip edge 311 of the glass sealing strip 30 and the outer lip edge 312 of the glass sealing strip 30 are respectively pressed against the inner and outer surfaces of the door glass 40 to form a seal on the side of the door glass 40, and at the same time, the two corner portions 32 located on the inner side of the door glass 40 respectively form an interference seal with the door frame sealing strip 10 on the front and rear sides of the B-pillar, thereby achieving the sealing of the door glass 40 at the top corner of the B-pillar; on this basis, the outer lip edge 312 of the glass sealing strip 30 and the outer lip edge 313 of the glass sealing strip 30 are respectively pressed against the inner and outer surfaces of the door glass 40 to form a seal on the side of the door glass 40, and at the same time, the two corner portions 32 located on the inner side of the door glass 40 and the door frame sealing strip 10 on the front and rear sides of the B-pillar are respectively used to form an interference seal. 2 directly extends to the upper boundary of the door glass 40, thereby preventing the joint position of the glass sealing strip 30 and the corner portion 32 from being exposed, thereby improving the exquisite appearance of the B-pillar trim 20; directly utilizing the outer lip edge 312 to interfere with the door frame sealing strip 10 for sealing, thereby avoiding the problem that the outer lip edge 312 presses the corner portion 32 upward when the door glass 40 is raised, thereby preventing the corner portion 32 from being deformed, which not only facilitates the insertion of the door glass 40 into the groove, but also improves the sealing reliability of the corner portion 32 between the door glass 40 and the top area of ​​the B-pillar.

[0032] In some embodiments, see Figure 3 and Figure 5 The corner portion 32 has a first sealing lip 321 and a second sealing lip 322 that are pressed against the inner surface of the vehicle door glass 40, and the lower ends of the first sealing lip 321 and the second sealing lip 322 are connected to the top end of the inner lip edge 311; wherein, the first sealing lip 321 extends upward along the boundary of the B-pillar trim 20 and interferes with the door frame sealing strip 10 for sealing; the second sealing lip 322 gradually moves away from the B-pillar trim 20 from bottom to top, and the top end of the second sealing lip 322 interferes with the door frame sealing strip 10 for sealing. Here, the first sealing lip 321 and the second sealing lip 322 can be understood as the inner lip edge 311 forking and extending upward from its top, wherein the first sealing lip 321 continues to interfere and seal with the door glass 40 along the boundary of the B-pillar trim 20, while the second sealing lip 322 begins to gradually move away from the B-pillar trim 20, thereby increasing the contact area between the second sealing lip 322 and the door glass 40 in the X direction, which can not only improve the sealing effect on the inner surface of the door glass 40, but also increase the lifting and lowering support effect on the door glass 40, especially when the door glass 40 is raised, it can ensure the alignment of the door glass 40 and the door frame sealing strip 10, thereby promoting the upper boundary of the door glass 40 to enter the groove smoothly.

[0033] It should be noted that, in this embodiment, the first sealing lip 321 has a first Y-direction interference amount with the inner surface of the door glass 40, and the second sealing lip 322 has a second Y-direction interference amount with the inner surface of the door glass 40, and the second Y-direction interference amount is smaller than the first Y-direction interference amount. The Y-direction interference amount is set to ensure the interference sealing effect on the inner surface of the door glass 40, and appropriately reducing the interference amount between the second sealing lip 322 and the door glass 40 can avoid the friction resistance between the second sealing lip 322 and the door glass 40 being too large, which causes the door glass 40 to be blocked from rising and falling, and is conducive to the door glass 40 to smoothly enter the groove when it is raised.

[0034] Specifically, the first Y-direction interference amount may be 2 mm to 3 mm, and the second Y-direction interference amount is 1 mm less than the first Y-direction interference amount, that is, the second Y-direction interference amount is 1 mm to 2 mm.

[0035] For some possible implementations, see Figure 1 , Figure 2 and Figure 5 The frameless window B-pillar sealing structure further includes a door sealing strip 50 , which cooperates with a boundary gap of the corner portion 32 away from the B-pillar trim 20 .

[0036] The door sealing strip 50 is used to seal the door boundary and the door frame boundary when the door is closed. Here, a clearance fit is adopted between the corner portion 32 and the door sealing strip 50 to prevent the door sealing strip 50 from deforming and excessively squeezing the corner portion 32 when the door is closed, thereby causing the door glass 40 to be squeezed out of the groove by the corner portion 32. This can reduce the risk of the door glass 40 being out of the groove and the wear of the corner portion 32 while ensuring the sealing effect.

[0037] In some embodiments, see Figure 5 The corner portion 32 has a third sealing lip 323 at the boundary away from the B-pillar trim 20. When the door glass 40 is opened, a buffer gap 500 is provided between the third sealing lip 323 and the door sealing strip 50. When the door glass 40 is closed, the third sealing lip 323 contacts the door sealing strip 50. Specifically, in the present embodiment, the matching gap between the door sealing strip 50 and the third sealing lip 323 is set to 1.2 mm to 1.5 mm. On the one hand, when the door is closed, the third sealing lip 323 can form a contact seal with the door sealing strip 50 through the deformation of the door sealing strip 50. On the other hand, the squeezing force of the door sealing strip 50 on the third sealing lip 323 can be reduced, thereby preventing the corner portion 32 from being excessively squeezed by the force to squeeze the door glass 40, causing the door glass 40 to fall out of the sealing groove of the door frame sealing strip 10, thereby improving the sealing reliability.

[0038] Specifically, Figure 5As shown, in this embodiment, the optional connection structure of the extrusion section 31 and the B-pillar trim 20 is that the front and rear boundaries of the B-pillar trim 20 are both provided with an embedding groove 21, and the side of the extrusion section 31 facing away from the door glass 40 is provided with a mounting strip 313, and the mounting strip 313 is embedded in the embedding groove 21. The inner lip 311 and the outer lip 312 both extend in a direction away from the B-pillar trim 20, and the extrusion section 31 extends in a direction away from the door glass 40, so that it can be embedded in the embedding groove 21 provided at the boundary of the B-pillar trim 20, and the installation is simple and convenient.

[0039] Of course, in order to prevent the installation strip 313 from slipping out of the embedded groove 21, in this embodiment, a slot is provided on one side of the slot wall of the embedded groove 21, and a clamping rib 3131 is provided on the installation strip 313. The clamping rib 3131 extends obliquely toward the mouth of the embedded groove 21 and is clamped with the slot. From the depth direction of the embedded groove 21, the clamping rib 3131 is equivalent to a barb structure. The clamping rib 3131 is clamped into the slot to prevent the installation strip 313 from slipping out of the embedded groove 21, thereby improving the connection reliability; specifically, two or more clamping slots can be arranged at intervals along the depth direction of the embedded groove 21, and the number of the clamping ribs 3131 matches the number of the clamping slots and is clamped one-to-one.

[0040] On the basis of the above, if Figure 5 As shown, a limiting rib 3132 is provided on the side of the installation strip 313 away from the clamping rib 3131, and the limiting rib 3132 abuts against the groove wall of the embedding groove 21 away from the clamping groove. The limiting rib 3132 is provided to support and limit the relative position of the installation strip 313 in the embedding groove 21, thereby ensuring the Y-axis position accuracy between the glass sealing strip 30 and the B-pillar trim 20, thereby improving the sealing effect and the smoothness of the door glass 40 entering the groove.

[0041] For some examples, see Figure 2 , the B-pillar trim 20 is provided with a mesh rib plate 22 at the position corresponding to the two corner portions 32, and the mesh rib plate 22 is used to support the corner portions 32. In the case where the outer lip 312 is not in contact with the corner portions 32, in order to prevent the inner lip 311 from squeezing the corner portions 32 and causing deformation of the corner portions 32, the mesh rib plate 22 is provided to support the corner portions 32 in the Y direction. When the door glass 40 is raised and closed, the corner portions 32 are clamped between the mesh rib plate and the door glass 40, so that the corner portions 32 can be prevented from being deformed by force and wrinkles to affect the sealing reliability, and at the same time, it is also beneficial for the corner portions 32 to accurately guide the upper boundary of the door glass 40 into the sealing groove of the door frame sealing strip 10.

[0042] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the above-mentioned frameless window B-pillar sealing structure.

[0043] Compared with the prior art, the vehicle provided by the present embodiment adopts the above-mentioned frameless window B-pillar sealing structure, and the outer lip edge 312 of the glass sealing strip 30 directly extends to the upper boundary of the door glass 40, thereby avoiding the exposure of the joining position between the glass sealing strip 30 and the corner portion 32, thereby improving the exquisite appearance of the B-pillar trim 20; the outer lip edge 312 is directly used to interfere with the sealing strip 10 of the door frame, thereby avoiding the problem that the outer lip edge 312 presses the corner portion 32 upward when the door glass 40 is raised, causing the corner portion 32 to deform, which not only facilitates the insertion of the door glass 40 into the groove, but also improves the sealing reliability of the corner portion 32 between the door glass 40 and the top area of ​​the B-pillar.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
