Positioning structure of b-pillar weather strip and vehicle

Abstract

The application provides a positioning structure of a B column sealing strip and a vehicle. The positioning structure is arranged on a B column decorative plate. The B column sealing strip has side connecting parts arranged on the two sides of the B column decorative plate respectively. The side surface of the B column decorative plate is provided with an insertion slot extending along the length direction of the decorative plate. The side connecting part comprises a connecting strip embedded in the insertion slot. The positioning structure comprises a positioning part arranged on the connecting strip and a stop part arranged on the slot wall of the insertion slot. The positioning part and the stop part are inserted or staggered in the thickness direction of the connecting strip and abut in the length direction. The positioning structure can enhance the connection stability of the B column sealing strip and the B column decorative plate. The area of the B column sealing strip in contact with the vehicle door glass, i.e. the fixed position of the connecting strip in the height direction of the vehicle body, is limited. The sealing strip is prevented from moving and being dislocated due to the lifting of the glass, so that good sealing performance is ensured. The problem that the sealing performance is affected due to the movement and dislocation of the sealing strip caused by the softening of the sealing strip after exposure to sunlight is solved.

Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a positioning structure for a B-pillar sealing strip and a vehicle including the B-pillar sealing strip positioning structure. Background Technology

[0002] More and more car models are adopting frameless door structures. While frameless structures offer a more novel appearance, they place higher demands on the design of the door sealing system. Frameless doors typically employ a split sealing system, which includes separately manufactured B-pillar sealing strips, front door frame sealing strips, and rear door frame sealing strips. The B-pillar sealing strip is first assembled separately from the B-pillar trim panel and then fitted onto the side B-pillar. The front and rear sides of the B-pillar sealing strip connect with the front and rear door frame sealing strips, and the top connects with the side window frame sealing strip, together forming a complete frameless door sealing structure to prevent rainwater intrusion.

[0003] B-pillar sealing strips are typically wrapped around the outer perimeter of the B-pillar trim panel, with the edges of the front and rear door windows pressing directly against the lip of the sealing strip. With use, after exposure to sunlight, the sealing strip softens, reducing its adhesion to the trim panel and causing it to lift. Furthermore, frequent window raising and lowering can cause the sealing strip to shift and misalign within the B-pillar trim panel, creating gaps with the top side window frame sealing strip or trim panel, thus reducing sealing performance. Utility Model Content

[0004] In view of this, this application aims to provide a positioning structure for a B-pillar sealing strip, which can enhance the connection stability between the B-pillar sealing strip and the B-pillar trim panel, prevent the sealing strip from shifting or becoming misaligned due to the movement of the glass, thereby ensuring good sealing performance and solving the problem that the sealing performance is affected by the softening of the rubber strip after exposure to sunlight and the resulting shifting or misalignment due to the movement of the glass.

[0005] This application provides a positioning structure for a B-pillar sealing strip, suitable for installation on a B-pillar trim panel and used for positioning the B-pillar sealing strip. The B-pillar sealing strip has side connecting portions respectively disposed on both sides of the B-pillar trim panel. The side of the B-pillar trim panel is provided with a slot extending along the length of the trim panel, and the side connecting part includes a connecting strip embedded in the slot. The positioning structure includes a positioning part disposed on the connecting strip and a stop part disposed on the slot wall. The positioning part and the stop part are inserted or staggered in the thickness direction of the connecting strip and are used to abut against each other in the length direction.

[0006] In one possible implementation, one of the positioning part and the stop part is a limiting protrusion and the other is a limiting groove into which the limiting protrusion is inserted. Alternatively, one of the positioning part and the stop part may be a first protrusion and the other a second protrusion, the first protrusion and the second protrusion being staggered in the length direction, and their projections in the length direction at least partially overlapping.

[0007] In one possible implementation, the positioning part is a limiting protrusion provided on the connecting strip, the stop part is a limiting groove provided on the slot wall, and the limiting groove is a notch groove recessed inward from the edge of the B-pillar decorative panel.

[0008] In one possible implementation, the B-pillar decorative panel includes a substrate and glass covering the substrate. Guide plates are provided on both sides of the substrate and spaced apart from the substrate in the thickness direction. The slot is formed between the guide plates and the substrate, and at least one of the limiting grooves is provided on the guide plates.

[0009] In one possible implementation, the limiting protrusion is block-shaped, or the limiting protrusion is strip-shaped extending along the width direction of the connecting strip.

[0010] In one possible implementation, the B-pillar sealing strip further includes a bottom connecting portion located at the bottom end of the two side connecting portions, and the limiting protrusion is provided in at least two sets, with at least one set located on the upper part of the connecting strip and at least one set located at the bottom end of the connecting strip that connects with the bottom connecting portion.

[0011] In one possible implementation, the B-pillar trim panel includes a main body and a mounting portion located at the bottom end of the main body, wherein the limiting protrusion disposed at the bottom end of the connecting strip partially extends onto the bottom connecting portion and is inserted into the mounting portion.

[0012] In one possible implementation, the B-pillar trim panel includes a main body and a mounting portion located at the bottom end of the main body. The side connecting portion is disposed on the side of the main body. The B-pillar sealing strip further includes a bottom connecting portion, the bottom connecting portion including a connecting piece covering the surface of the mounting portion. The connecting piece is provided with multiple buckles that are positioned and engaged with the mounting part.

[0013] In one possible implementation, the thickness of the connecting piece is 3mm-5mm; And / or, the connecting piece is further provided with a clamping lip on the side facing the mounting portion, the clamping lip and the connecting piece forming a groove and configured to hook the bottom end of the mounting portion; And / or, the mounting portion is provided with a mounting groove on the side facing the connecting piece, and the connecting piece is provided with a support protrusion extending into the mounting groove in the area corresponding to the mounting groove.

[0014] This application also provides a vehicle, including a body, wherein the B-pillar of the body is provided with a positioning structure for the B-pillar sealing strip as described in any of the preceding claims.

[0015] The positioning structure provided in this application increases the positioning and docking of the B-pillar sealing strip and the B-pillar trim panel, limiting the position of the B-pillar sealing strip in the length direction of the trim panel (i.e., the height direction of the vehicle body) and the lifting direction of the door glass. This enhances the connection stability between the B-pillar sealing strip and the B-pillar trim panel, reduces the degree of separation between the B-pillar sealing strip and the B-pillar trim panel after softening, and effectively prevents the B-pillar sealing strip from shifting or misaligning due to friction caused by the lifting of the glass. This ensures sealing performance and solves the problem that the rubber strip softens after being exposed to sunlight and is prone to shifting or misaligning under the movement of the glass, thus affecting the sealing performance.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Please refer to the attached document. Figure 1-9 This application provides a positioning structure for a B-pillar sealing strip 100. This positioning structure is suitable for being installed on a B-pillar trim panel 200 and is used to position the B-pillar sealing strip 100, which is arranged circumferentially along the B-pillar trim panel 200. The B-pillar sealing strip 100 has side connecting portions 110 respectively provided on both sides of the B-pillar trim panel 200 and bottom connecting portions 120 located at the bottom ends of the two side connecting portions 110. The B-pillar trim panel 200 includes a main body portion 210 and a mounting portion 220 located at the bottom end of the main body portion 210. The main body portion 210 is the area exposed on the outer surface of the vehicle body and may be covered with glass 23. The mounting portion 220 is used to connect to the B-pillar of the vehicle body and is covered by the B-pillar sealing strip 100. The side connecting portions 110 of the B-pillar sealing strip 100 are connected to the side of the main body portion 210, and the bottom connecting portions 120 are connected to the mounting portions 220.

[0028] The B-pillar sealing strip 100 can be U-shaped or a closed rectangular ring. When the top of the B-pillar sealing strip 100 does not have the rubber strip segment connecting the two side connecting parts 110, it is U-shaped, and the top of the B-pillar trim panel 200 is sealed by the side sealing strip. When the top of the B-pillar sealing strip 100 has a top connecting part connecting the two side connecting parts 110, it is a closed ring. The side connecting parts 110 of the B-pillar sealing strip 100 are located on the side of the main body 210 of the B-pillar trim panel 200, used to seal the door glass 23 and provide a track for the door glass 23 to slide up and down. This part is most easily affected by the raising and lowering of the door glass 23.

[0029] In this application, the sides of the B-pillar trim panel 200 (referring to the two sides of the main body 210 in its width direction and also in the length direction of the vehicle body) are provided with slots 201 extending along the length direction of the trim panel (also in the height direction of the vehicle body). The side connecting part 110 includes a connecting strip 11 embedded in the slot 201 and lips such as a first lip 14 and a second lip 15 located outside the slot 201. A positioning and docking structure is also provided between the connecting strip 11 and the groove wall of the slot 201 to limit the position of the connecting strip 11 in the length direction. For example, a positioning part is provided on the connecting strip 11, and a stop part is provided on the groove wall of the slot 201. The positioning part and the stop part are inserted or staggered in the thickness direction of the connecting strip 11 and are used to abut against each other in the length direction of the trim panel. In this way, the B-pillar trim panel 200 can limit the fixed position of the B-pillar sealing strip 100 in the height direction of the vehicle body by stopping the positioning part on the connecting strip 11. Even if the B-pillar sealing strip 100 softens and loosens after being exposed to the sun, it cannot move or misalign when it is moved by the friction of the door glass 23 rising and falling, thus effectively maintaining good sealing performance.

[0030] As can be seen, the positioning structure of the B-pillar sealing strip 100 provided in this application, by increasing the positioning and docking of the side connecting part 110 of the B-pillar sealing strip 100 and the B-pillar decorative panel 200, limits the fixed position of the long strip connecting strip 11 on the B-pillar sealing strip 100 in the length direction of the decorative panel, that is, the height direction of the vehicle body and the lifting direction of the door glass 23, thereby enhancing the connection stability between the B-pillar sealing strip 100 and the B-pillar decorative panel 200, reducing the degree of separation between the B-pillar sealing strip 100 and the B-pillar decorative panel 200 after softening, and effectively preventing the B-pillar sealing strip 100 from moving and misaligning due to the friction of the glass 23 rising and falling, thereby ensuring sealing performance and solving the problem that the rubber strip is easily moved and misaligned due to the movement of the glass 23 after softening after being exposed to the sun, thus affecting the sealing performance.

[0031] The positioning part can be a limiting protrusion 101 formed on the connecting strip 11, and the stop part has a limiting surface that abuts against the limiting protrusion 101. The limiting surface can be formed on the protrusion or it can be the groove wall of the groove.

[0032] For example, the positioning and docking structure includes a limiting protrusion 101 provided on one of the connecting bar 11 and the groove wall of the slot 201, and a limiting groove 202 provided on the other. Alternatively, one of the positioning part and the stop part is the limiting protrusion 101, and the other is the limiting groove 202 into which the limiting protrusion 101 is inserted.

[0033] Thus, by inserting the limiting protrusion 101 into the limiting groove 202, the groove wall of the limiting groove 202 in the vehicle height direction stops the limiting protrusion 101, which can stably limit the position of the connecting strip 11 in the vehicle height direction and enhance stability.

[0034] Alternatively, the positioning and docking structure includes a first protrusion on one of the connecting strip 11 and the groove wall of the slot 201, and a second protrusion on the other. In other words, one of the positioning part and the stop part is the first protrusion, and the other is the second protrusion. The first and second protrusions are staggered along the length of the decorative panel, and their projections along the length of the decorative panel at least partially overlap. Alternatively, each pair of adjacent first protrusions forms a limiting groove 202, and a second protrusion inserted between two adjacent first protrusions forms a limiting protrusion 101.

[0035] In some embodiments, the positioning and docking structure includes a limiting protrusion 101 provided on the connecting strip 11 and a limiting groove 202 provided on the groove wall of the slot 201. The limiting groove 202 is a notch groove recessed inward from the edge of the B-pillar decorative panel 200.

[0036] The limiting protrusion 101 can be in the form of a protrusion, a protruding strip, or a protruding piece. The limiting groove 202 is a notch groove, that is, it is formed by a notch set on the edge of the decorative panel. When the connecting strip 11 is inserted into the slot 201 from the side, the limiting protrusion 101 can be directly embedded into the limiting groove 202, which can simplify the connection operation of assembling the sealing strip on the decorative panel.

[0037] On a single side connecting portion 110, there may be one or more limiting protrusions 101. For example, at least two limiting protrusions 101 may be provided, with at least one located on the upper part of the connecting strip 11 (the upper part of the connecting strip 11 refers to the section closer to the roof along the center line of the connecting strip 11's length), referred to as upper protrusion 101a; and at least one limiting protrusion 101 located at the bottom of the connecting strip 11, referred to as bottom protrusion 101b. Correspondingly, on one side of the B-pillar trim panel 200, one or more limiting grooves 202 are also provided, with a one-to-one arrangement of limiting grooves 202 and limiting protrusions 101.

[0038] In some embodiments, at least two sets of limiting protrusions 101 are provided, with at least one set located on the upper part of the connecting strip 11, such as the upper protrusion 101a, and at least one set located at the bottom end of the connecting strip 11 that connects to the bottom connecting part 120, such as the bottom protrusion 101b. When the sealing strip softens due to exposure to sunlight, the corner area of ​​the side connecting part 110 and the bottom connecting part 120 is prone to misalignment or outward turning, posing a risk of detachment from the corner of the glass 23 on the decorative panel. Once the B-pillar sealing strip 100 is misaligned, outward turning, or detached at this location, it is difficult for it to automatically reset. Providing a set of limiting protrusions 101 and limiting grooves 202 near the corner enhances the positioning connection between the sealing strip and the decorative panel, strengthens the positional stability of the sealing strip in this area, and effectively prevents the sealing strip in this area from turning outward or misaligning.

[0039] The B-pillar trim panel 200 includes a base plate 21 and glass 23 covering the base plate 21. The area of ​​the base plate 21 covered with glass 23 and the glass 23 together form a main body 210. The area of ​​the base plate 21 extending beyond the main body 210 forms a mounting portion 220. Meanwhile, guide plates 22 are provided on both sides of the base plate 21, spaced apart from the base plate 21 in the thickness direction, and slots 201 are formed between the guide plates 22 and the base plate 21. At least one limiting groove 202 is provided on the guide plate 22. For example, the limiting groove 202 corresponding to the upper protrusion 101a is provided on the guide plate 22.

[0040] The position of the limiting groove 202 corresponding to the bottom protrusion 101b depends on the specific position of the bottom protrusion 101b. When the bottom protrusion 101b is located at the bottom end of the connecting strip 11, the limiting groove 202 corresponding to the bottom protrusion 101b is located on the mounting portion 220 of the substrate 21 and is positioned opposite to the bottom end of the guide plate 22.

[0041] Furthermore, the limiting protrusion 101 provided at the bottom end of the connecting strip 11 extends partially to the bottom connecting portion 120 and is inserted into the mounting portion 220 of the B-pillar decorative panel 200; the limiting groove 202 into which the limiting protrusion 101 is embedded is located at the bottom end of the guide plate 22 in the length direction, and extends inward from the edge of the decorative panel to the mounting portion 220 in the width direction of the decorative panel.

[0042] The limiting protrusion 101 may be in the form of a block, or the limiting protrusion 101 may be in the form of a strip extending along the width direction of the connecting strip 11.

[0043] Preferably, the upper protrusion 101a is block-shaped; the bottom protrusion 101b is strip-shaped extending along the width direction of the connecting strip 11.

[0044] The bottom connecting portion 120 of the B-pillar sealing strip 100 includes a connecting piece 12 covering the surface of the mounting portion 220. Multiple clips 102 are provided on the connecting piece 12 and are positioned and engaged with the mounting portion 220. The clips 102 can be integrally injection molded onto the connecting piece 12, and the clips 102 and the connecting piece 12 are a single integrated structure. The entire B-pillar sealing strip 100 can also be a single integrated structure.

[0045] The connecting piece 12 covers the bottom of the base plate 21, which is used to connect with the B-pillar of the vehicle body, i.e., the mounting part 220, to avoid gaps between the trim panel and the B-pillar. The top of the connecting piece 12 abuts against the bottom of the glass 23 on the base plate 21. Alternatively, the B-pillar sealing strip 100 is connected to the base plate 21 and wraps around the glass 23 circumferentially. After the sealing strip is exposed to sunlight, the top of the connecting piece 12 may fold outwards, creating a gap between it and the glass 23. Therefore, in some embodiments, the thickness of the connecting piece 12 can be set to 3mm-5mm, such as 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc., or any other value within this range. Preferably, the thickness of the connecting piece 12 can be 4mm. A suitable thickness of the connecting piece 12 can enhance toughness, enhance high-temperature resistance, and reduce softening, avoiding excessive softening due to excessive thinness, or preventing it from being too hard and affecting the fit and sealing with the trim panel.

[0046] like Figure 4 , Figure 6 and Figure 8 As shown, in some embodiments, the connecting piece 12 is further provided with a clamping lip 13 on the side facing the mounting portion 220. The clamping lip 13 and the connecting piece 12 form a groove and are configured to hook the bottom end of the mounting portion 220. With this configuration, in the vehicle height direction, the entire B-pillar sealing strip 100 can be tightened and clamped onto the B-pillar trim panel 200, which helps to enhance the tightness of the sealing strip in this direction and helps to resist the degree of softening, deformation and misalignment after exposure to sunlight.

[0047] In some embodiments, the mounting portion 220 has a mounting groove 203 on the side facing the connecting piece 12, and the connecting piece 12 has a support protrusion 103 extending into the mounting groove 203 in the area corresponding to the mounting groove 203. The mounting groove 203 is used to accommodate screws connecting the decorative panel and the B-pillar of the vehicle body. The support protrusion 103 on the connecting piece 12 extending into the mounting groove 203 can enhance the flatness of the connecting piece 12 on the surface of the mounting portion 220.

[0048] This application also provides a vehicle, including a body, wherein the B-pillar of the body is provided with a positioning structure for the B-pillar sealing strip 100 as described in any of the preceding embodiments.
