Description

Technical Field

[0001] This utility model relates to the field of vehicle parts, and in particular to an edge-wrapping structure and a vehicle. Background Technology

[0002] As the integration of automotive sunroof edging technology continues to improve, edging components and edging materials are often manufactured using a one-piece molding process. To create the cavity structure required for assembly (such as a bolt mounting cavity) between the two, a sealant structure needs to be installed on the edging component.

[0003] In related technologies, a triangular cross-section annular reinforcing rib structure is typically used as the adhesive-blocking structure. This structure achieves melt barrier through a zero-gap fit between the top and the edge banding component. The annular reinforcing rib structure effectively prevents adhesive from penetrating into the cavity area formed by the edge banding component and the load-bearing component. While meeting structural strength and dimensional stability requirements, the geometric parameters of this triangular annular reinforcing rib structure must also strictly adhere to anti-shrinkage design specifications to ensure appearance quality.

[0004] During injection molding, the profile tolerance of the top edge of the reinforcing rib structure is difficult to guarantee a completely conformal contact with the edging component. A small clearance exists between the edging component and the load-bearing component, which is more pronounced when the upper surface of the edging component has an arc-shaped profile. For cavities with small perimeters, the ribs can form an effective interference seal through elastic deformation. However, as the cavity size and the perimeter of the reinforcing rib structure increase, the cumulative form and position tolerance of its top profile grows non-linearly, leading to a significant increase in the clearance between the reinforcing rib structure and the edging component. This results in decreased sealing performance, and adhesive easily seeps into the cavity area from the gap, affecting the structural integrity of the product. Utility Model Content

[0005] Therefore, it is necessary to provide an edge-sealing structure that can prevent adhesive leakage from the bonding area into the cavity area and is suitable for cavity structures with a large perimeter.

[0006] An edge-sealing structure includes a support member and an edge-sealing member fixed to the support member; An adhesive bonding area and a cavity area are formed between the bearing member and the edge-binding member. The adhesive bonding area is formed on the periphery of the cavity area, and a glue-blocking structure is provided at the connection between the adhesive bonding area and the cavity area. One end of the adhesive-blocking structure is fixedly connected to one of the carrier and the edge-sealing component, and the other end of the adhesive-blocking structure abuts against the other of the carrier and the edge-sealing component.

[0007] In one embodiment, an adhesive layer is provided between the adhesive barrier structure and the carrier member, and the adhesive barrier structure is bonded to the carrier member through the adhesive layer.

[0008] In one embodiment, an adhesive layer is provided between the adhesive barrier structure and the edge banding component, and the adhesive barrier structure is bonded to the edge banding component through the adhesive layer.

[0009] In one embodiment, the adhesive-blocking structure includes a second connecting portion, and the edge-sealing component has a snap-fit ​​groove, wherein the second connecting portion is tightly fitted and snapped into the snap-fit ​​groove.

[0010] In one embodiment, the distance between the two opposite side walls of the snap-fit ​​groove gradually decreases from the bottom of the snap-fit ​​groove to the opening of the snap-fit ​​groove.

[0011] In one embodiment, the adhesive barrier structure has a rectangular or inverted trapezoidal cross-section in the length direction.

[0012] In one embodiment, the adhesive barrier structure is made of an elastic material.

[0013] In one embodiment, the support member is glass, and the edging member is an injection molded part.

[0014] In one embodiment, the adhesive barrier structure is a one-piece molded structure.

[0015] This application also provides a vehicle including the edge-sealing structure described above.

[0016] In the above solution, by setting a sealant structure at the connection between the adhesive bonding area and the cavity area, one end of the sealant structure is fixedly connected to one of the carrier and the edge-sealing component, and the other end of the sealant structure abuts against the other of the carrier and the edge-sealing component to form a sealed interface, thereby forming a clear isolation barrier between the adhesive bonding area and the cavity area, thus preventing the adhesive in the adhesive bonding area from leaking into the cavity area, and this application is applicable to cavity structures with a larger perimeter.

[0031] As the integration of automotive sunroof edging technology continues to improve, the edging component 3 and the edging material are often manufactured using an integrated molding process. To create the cavity structure required for assembly (such as a bolt mounting cavity) between the two, a sealant structure needs to be provided on the edging component 3.

[0032] In related technologies, a ring-shaped reinforcing rib structure 1 with a triangular cross-section is typically used as the adhesive-blocking structure, such as... Figure 1 As shown, this structure achieves melt barrier through a zero-gap fit between the top and the edge banding 3. The annular reinforcing rib structure 1 effectively prevents adhesive from seeping into the cavity area 5 formed by the edge banding 3 and the support rib 2. While meeting structural strength and dimensional stability requirements, the geometric parameters of this triangular annular reinforcing rib structure 1 must also strictly adhere to anti-shrinkage design specifications to ensure appearance quality.

[0033] During injection molding, the profile tolerance of the top of the reinforcing rib structure 1 is difficult to guarantee complete conformal contact with the edge trim 3. For example... Figure 2 As shown, there is a small gap between the edging component 3 and the bearing component 2. This gap is more pronounced when the upper surface of the edging component 3 has an arc-shaped profile. For cavities with a small perimeter, the ribs can form an effective interference seal through elastic deformation. However, when the cavity size increases and the perimeter of the reinforcing rib structure 1 increases, the cumulative form and position tolerance of its top profile increases non-linearly. This leads to a significant increase in the gap between the reinforcing rib structure 1 and the edging component 3, resulting in a decrease in sealing performance. Adhesive can easily seep into the cavity area from the gap, affecting the structural integrity of the product.

[0034] See Figure 3 , Figure 4 , Figure 6 and Figure 7 The embodiments of this application relate to an edge-sealing structure 10, including a support member 100 and an edge-sealing member 200 fixed to the support member 100.

[0035] A bonding area 300 and a cavity area 400 are formed between the carrier 100 and the edge-sealing part 200. The bonding area 300 is formed around the cavity area 400, and a sealant structure 500 is provided at the connection between the bonding area 300 and the cavity area 400. Adhesive is applied to the bonding area 300 to achieve bonding and fixation between the carrier 100 and the edge-sealing part 200. Specifically, the sealant structure 500 is made of an elastic material. The carrier 100 is made of glass. The sealant structure 500 is made of foam. The edge-sealing part 200 is an injection-molded part.

[0036] One end of the adhesive-blocking structure 500 is fixedly connected to one of the bearing member 100 and the edge-sealing member 200, and the other end of the adhesive-blocking structure 500 abuts against the other of the bearing member 100 and the edge-sealing member 200.

[0037] By fixing one end of the adhesive barrier structure 500 to one of the carrier 100 and the edge banding 200, and abutting the other end of the adhesive barrier structure 500 to the other of the carrier 100 and the edge banding 200, a sealed interface is formed to create a clear isolation barrier between the adhesive bonding area 300 and the cavity area 400, thereby preventing the adhesive in the adhesive bonding area 300 from leaking into the cavity area 400. At the same time, this application is applicable to cavity structures with a larger perimeter.

[0038] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7 According to some embodiments of this application, optionally, in this embodiment, an adhesive layer is provided between the adhesive-blocking structure 500 and the carrier 100, and the adhesive-blocking structure 500 is bonded to the carrier 100 through the adhesive layer. Exemplarily, the adhesive layer is a backing adhesive. It should be noted that the adhesive layer can be pre-installed on the adhesive-blocking structure 500 to facilitate the installation of the adhesive-blocking structure 500 and the carrier 100. In this embodiment, the adhesive-blocking structure 500 has a rectangular cross-section in the length direction.

[0039] In other embodiments, an adhesive layer is provided between the adhesive barrier structure 500 and the edge banding member 200, and the adhesive barrier structure 500 is bonded to the edge banding member 200 through the adhesive layer.

[0040] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6According to some embodiments of this application, optionally, the adhesive barrier structure 500 includes a second connecting part, and the edge banding 200 has a snap-fit ​​groove 210, and the second connecting part is tightly fitted and snapped into the snap-fit ​​groove 210.

[0041] By setting the snap-fit ​​groove 210, the second connecting part fits tightly and snaps into the snap-fit ​​groove 210. The elastic force of the adhesive barrier structure 500 and the constraint of the snap-fit ​​groove 210 can be used to tightly fit the adhesive barrier structure 500 into the snap-fit ​​groove 210, eliminating the need for an adhesive layer, simplifying the installation process of the adhesive barrier structure 500, and reducing material and processing costs. This method does not rely on surface adhesive performance and is suitable for edge-binding parts 200 of various materials, with good versatility and stability.

[0042] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 According to some embodiments of this application, optionally, the distance between the two side walls of the snap-fit ​​groove 210 gradually decreases from the bottom 211 of the snap-fit ​​groove 210 to the opening 212 of the snap-fit ​​groove 210. The snap-fit ​​groove 210 is formed on the side of the edge banding member 200 near the support member 100, and the opening 212 of the snap-fit ​​groove 210 faces the support member 100. In this embodiment, the adhesive-blocking structure 500 has an inverted trapezoidal cross-section in the length direction. The snap-fit ​​groove 210 has an inverted trapezoidal cross-section in the length direction.

[0043] It should be noted that the adhesive barrier structure 500 is formed on the periphery of the cavity region 400, and the length direction of the adhesive barrier structure 500 refers to the longitudinal direction of the adhesive barrier structure 500, that is, the length direction of the adhesive barrier structure 500 is set around the periphery of the cavity region 400.

[0044] It should be noted that the shape of the snap-fit ​​groove 210 is adapted to the shape of the second connecting part of the adhesive barrier structure 500, which can not only ensure the sealing performance between the second connecting part and the snap-fit ​​groove 210, but also improve the connection strength between the second connecting part and the snap-fit ​​groove 210.

[0045] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7 According to some embodiments of this application, optionally, the adhesive barrier structure 500 is an integrally molded structure.

[0046] This application also provides a vehicle including the edging structure 10 as described above.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
