The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0042] The purpose of the present disclosure is to provide a seal 100, a sealing structure and a vehicle. The seal 100 is arranged between the frameless door glass 200 and the triangular window 300, and forms two seals through the first sealing part 130 and the second sealing part 140, which has a good sealing effect and improves the NVH performance of the vehicle. At the same time, the overall structure is simple and the cost is low.

[0043] In order to achieve the above purpose, Figures 1 to 7 As shown, according to a first aspect of the present disclosure, a seal 100 is provided for sealing between a frameless door glass 200 and a triangular window 300. The seal 100 includes a sealing body 110, a connecting portion 120, a first sealing portion 130, and a second sealing portion 140. The connecting portion 120 is used to connect to the frame 310 of the triangular window 300. The first sealing portion 130 is used to seal between the frame 310 of the triangular window 300 and the side edge of the frameless door glass 200. The second sealing portion 140 is used to seal the inner sidewall of the frameless door glass 200 on the side closest to the triangular window 300.

[0044] The seal 100 disclosed herein, through the above-described technical solution, can be used to seal between a frameless door glass 200 and a triangular window 300. The seal 100 comprises a sealing body 110, a connecting portion 120, a first sealing portion 130, and a second sealing portion 140. The connecting portion 120 is used to connect to the frame 310 of the triangular window 300, the first sealing portion 130 is used to seal between the frame 310 of the triangular window 300 and the side edge of the frameless door glass 200, and the second sealing portion 140 is used to seal the inner sidewall of the frameless door glass 200 near the triangular window 300. Through the above-described arrangement, the seal 100 disclosed herein is disposed between the frameless door glass 200 and the triangular window 300, and forms a double seal through the first sealing portion 130 and the second sealing portion 140, achieving excellent sealing performance and improving NVH performance. Furthermore, the overall structure is simple and the cost is low.

[0045] It should be noted that the seal 100 can be used for sealing vehicles without a C-pillar, specifically, between a frameless rear door and the rear triangular window 300. In a frameless door system without a C-pillar, the triangular window 300 includes a frame 310 and a triangular glass 320 mounted within the frame 310. The seal 100 is connected to the frame 310 and positioned between the triangular window 300 and the frameless door glass 200. Its first sealing portion 130 acts as a seal between the triangular window 300 and the frameless door glass 200, acting as a C-pillar sealing strip. The second sealing portion 140 seals the inner sidewall of the frameless door glass 200 and the frame 310, forming a double seal. The seal 100 integrates the C-pillar sealing strip, the second sealing strip, and the rear triangular window 300 assembly, resulting in a simple structure and low cost.

[0046] It is understandable that the seal 100 can be made in an integral molding manner, and its material can be a sealing strip or sealing ring material disclosed in the relevant technology, including but not limited to rubber, PVC, EPDM, silicone, NBR, polyurethane, etc.

[0047] like Figure 4 As shown, in some embodiments, the outer side of the first sealing portion 130 is flush with the outer side of the frameless door glass 200 ; or, the outer side of the first sealing portion 130 is located inside the outer side of the frameless door glass 200 .

[0048] Among them, after installation, the first sealing part 130 can be located between the frame 310 of the triangular window 300 and the frameless door glass 200, and abut against both of them respectively, and can be used for sealing between the two. Since the outer side surface of the first sealing part 130 is flush with the outer side surface of the frameless door glass 200 or is located within the outer side surface of the frameless door glass 200, there is no need to set corresponding decorative parts on the outside of the first sealing part 130. Compared with the structure with a C-pillar, it is equivalent to reducing the C-pillar interior panel, which not only reduces the cost, but also simplifies the matching and improves the vehicle appearance matching performance.

[0049] like Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, the first sealing portion 130 extends from the sealing body 110 toward the frameless door glass 200 and bends inward. Specifically, the first sealing portion 130 extends toward the side edge of the frameless door glass 200 and, to better seal with the side edge of the glass and enhance aesthetics, is also bent inward. When the frameless door glass 200 abuts the first sealing portion 130, the first sealing portion 130 slightly bends inward and tightly adheres to the side edge of the frameless door glass 200 (the edge facing the triangular window 300).

[0050] In some embodiments, the second sealing portion 140 may include at least one sealing lip 141 that extends from the sealing body 110 toward the inner sidewall of the frameless door glass 200 and bends toward the first sealing portion 130. The second sealing portion 140 may include one or more sealing lips 141 connected to the sealing body 110 and extending outward and toward the first sealing portion 130. When the frameless door glass 200 contacts the sealing lip 141, the sealing lip 141 bends toward the triangular window 300 to more tightly adhere to the inner sidewall of the frameless door glass 200, forming a secondary seal. The sealing effect of the first sealing portion 130 and the second sealing portion 140 further enhances the sealing effect between the frameless door glass 200 and the triangular window 300, preventing dust intrusion and providing effective dust protection. Furthermore, NVH and wind noise are significantly reduced during vehicle operation.

[0051] like Figure 4 、 Figure 5 and Figure 6 As shown, the number of sealing lips 141 can be selected based on actual needs. In some embodiments, there are two sealing lips 141 spaced apart. The two sealing lips 141 can better adhere to the inner wall of the frameless door glass 200, avoiding the possibility of poor sealing due to deformation of some sealing lips 141. It should be noted that the second sealing portion 140 can also include three or more sealing lips 141 spaced apart.

[0052] In order to adapt to the deformation of the second sealing portion 140 and improve the sealing between the frameless door glass 200, as shown in FIG. Figure 4 and Figure 6 As shown, optionally, the sealing body 110 includes a cavity 111 located between the second sealing portion 140 and the connecting portion 120, and / or the sealing body 110 also includes a bending portion 113 located between the second sealing portion 140 and the connecting portion 120, and the bending portion 113 is bent in a direction away from the first sealing portion 130.

[0053] In some embodiments, the sealing body 110 may include a cavity 111 located between the second sealing portion 140 and the connecting portion 120. Because the cavity 111 is located on the sealing body 110 between the second sealing portion 140 and the connecting portion 120, when the second sealing portion 140 abuts the frameless door glass 200, both the second sealing portion 140 and the sealing body 110 may deform to some extent, thereby pressing the second sealing portion 140 against the inner sidewall of the frameless door glass 200. This allows the second sealing portion 140 to better adhere to the inner sidewall of the frameless door glass 200, further improving the sealing effect between the two. It is understood that the provision of the aforementioned cavity 111 on the sealing body 110 can also reduce the weight of the entire seal 100, thereby reducing material costs while ensuring sealing quality.

[0054] In other embodiments, the sealing body 110 further includes a bent portion 113 located between the second sealing portion 140 and the connecting portion 120. The bent portion 113 bends away from the first sealing portion 130 to reduce strength at that location and facilitate bending of the sealing body 110 at the bent portion 113. By providing the aforementioned bent portion 113 on the sealing body 110 between the second sealing portion 140 and the connecting portion 120, the portion of the sealing body 110 connected to the second sealing portion 140 can be easily rotated to the right when the second sealing portion 140 abuts the frameless door glass 200, thereby improving the sealing effect of the seal 100. It will be appreciated that one or more bent portions 113 may be provided to meet sealing requirements based on actual needs or material differences.

[0055] In yet other embodiments, the sealing body 110 may include a cavity 111 located between the second sealing portion 140 and the connecting portion 120. Furthermore, the sealing body 110 may also include a bent portion 113 located between the second sealing portion 140 and the connecting portion 120, with the bent portion 113 being bent in a direction away from the first sealing portion 130. The cavity 111 and the bent portion 113 may be provided to achieve the same effect as described above, i.e., while improving sealing, weight may also be reduced.

[0056] like Figure 4 and Figure 7 As shown, in some embodiments, the frame 310 of the triangular window 300 extends inward and includes a track 311, with the connecting portion 120 snapped into place within the track 311. The track 311 includes a snap-fit ​​structure that mates with the connecting portion 120. Since the seal 100 is typically made of an elastic material, it can be compressed and deformed to become snapped into place within the track 311. This snap-fit ​​connection between the connecting portion 120 and the frame 310 is simple and convenient, and also facilitates repair and replacement of the seal 100.

[0057] The specific snap-fit ​​structure between the connection portion 120 and the rail 311 can adopt any suitable structural form in the relevant art. In some embodiments, the connection portion 120 may include a first snap-fit ​​portion 121 for snapping with one side of the rail 311 and a second snap-fit ​​portion 122 for snapping with the other side of the rail 311. The first snap-fit ​​portion 121 is connected to one side of the rail 311, and the second snap-fit ​​portion 122 is connected to the other side of the rail 311. The specific connection structure can refer to the configuration of the rail 311, including but not limited to snap-fit ​​or slot forms.

[0058] like Figure 4 、 Figure 6 and Figure 7 As shown, in some embodiments, the first clamping portion 121 and / or the second clamping portion 122 are configured as a slot or a buckle. The track 311 is formed with a track 311 buckle corresponding to the first clamping portion 121, and a track 311 slot corresponding to the second clamping portion 122 is formed on the other side. The first clamping portion 121 can be a first slot formed on the sealing body 110, and the second clamping portion 122 can be a first buckle extending outward from the sealing body 110. The track 311 buckle on one side of the track 311 is snapped into the first slot, and the first buckle is snapped into the track 311 slot on the other side of the track 311, thereby achieving the connection between the sealing member 100 and the frame 310. It is understandable that the first clamping portion 121 and the second clamping portion 122 can also be a buckle and a slot, respectively, and the structures on both sides of the frame 310 can be redesigned accordingly.

[0059] In some embodiments, the sealing body 110 between the first clamping portion 121 and the second clamping portion 122 is formed with a support lip 112 for contacting the inner sidewall of the track 311, thereby forming a water channel 400 between the sealing body 110 and the inner sidewall of the track 311. The provision of the support lip 112 enables the frame 310 to support the sealing body 110 and provide a buffering function when the sealing body 110 is subjected to impact. Furthermore, since the support lip 112 supports the sealing body 110 and the inner sidewall of the track 311, a gap is formed therebetween. Furthermore, since the first clamping portion 121 and the second clamping portion 122 respectively engage with the clamping seals on both sides of the track 311, a water channel 400 can be formed between the sealing body 110 and the inner sidewall of the track 311 to drain a small amount of rainwater that intrudes between them. It should be noted that the bottom of the water guide groove 400 needs to be provided with a corresponding drainage outlet or be connected to a corresponding drainage channel to discharge the water in the water guide groove 400.

[0060] like Figure 4 and Figure 6As shown, the two spaced support lips 112 provided between the sealing body 110 and the inner wall of the track 311 are exemplary. It is understandable that one, three or more support lips 112 can be designed according to actual needs to meet the support and buffering requirements.

[0061] In some embodiments, the seal 100 includes an integrally formed first body 110a and a second body 110b; wherein the strength of the first body 110a is greater than that of the second body 110b; the first body 110a includes a connecting portion 120 and a first sealing portion 130; and the second body 110b includes a second sealing portion 140.

[0062] like Figure 6 As shown, the seal 100 can be integrally formed from a first body 110a and a second body 110b of different strengths, wherein the first body 110a can be made of dense glue and the second body 110b can be made of sponge glue. That is, the first sealing portion 130, the connecting portion 120 for connecting to the frame 310, and part of the sealing body 110 can be made of dense glue to ensure connection strength, while the second sealing portion 140 and part of the sealing body 110 can be made of sponge glue, which can be more easily deformed and adhered to the frameless door glass 200 to ensure the sealing effect. The first body 110a can be made of rubber, PVC, silicone, nitrile rubber, polyurethane, etc., and the second body 110b can be made of EPDM (Ethylene Propylene Diene Monomer, a copolymer of ethylene, propylene and a small amount of non-conjugated diene, a type of ethylene propylene diene rubber).

[0063] In which, the above-mentioned cavity 111 can be formed between the first body 110a and the second body 110b, and the above-mentioned bending portion 113 can be located in the depression on the second body 110b between the first sealing portion 130 and the second sealing portion 140, so that the second body 110b can bend to the right when it contacts the frameless door glass 200, thereby achieving a tighter fit and seal between the two.

[0064] like Figure 1 、 Figure 2 and Figure 3 As shown, according to the second aspect of the present disclosure, a sealing structure is provided, which includes a frameless door glass 200, a triangular window 300 and the above-mentioned seal 100. Therefore, the sealing structure also has all the advantages of a single seal 100, which will not be repeated here.

[0065] In some embodiments, the frameless door glass 200 may be a rear door movable glass of a vehicle without a C-pillar. The connecting portion 120 of the seal 100 is installed in the track 311 of the frame 310 of the triangular window 300 and is located between the rear door movable glass and the triangular window 300 .

[0066] The rear door's movable glass, sealing strip, and triangular window 300 together form the C-pillar-less sealing system for the frameless door. This sealing strip, integrated with the C-pillar sealing strip, forms a sealing system with the triangular window 300. This significantly reduces NVH (Wind Noise, Harshness) noise while the vehicle is in motion, while also preventing dust intrusion and providing excellent dust protection. Its simple design also enhances vehicle exterior compatibility.

[0067] It should be noted that the frame 310 can be made of aluminum alloy material, and the track 311 can be made of aluminum alloy extrusion.

[0068] like Figure 1 As shown, according to the third aspect of the present disclosure, a vehicle is also provided, which includes the above-mentioned sealing structure. Therefore, the vehicle also has all the advantages of the above-mentioned seal 100 and sealing structure, which will not be described here one by one.

[0069] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0071] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
