Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a roof assembly and a vehicle. Background Technology

[0002] Some vehicles are equipped with sunroofs, requiring an opening in the roof. A reinforcing frame is typically installed at this opening. To improve product quality, the roof fabric is usually used to create an edging at the cut edge of the inner flange of the reinforcing frame. However, existing edging solutions for sunroof openings have the following technical problems: Using ceiling fabric to create the edging makes it difficult to balance cost and quality. Currently, there are two common ceiling edging processes: Figure 5 As shown, the first edge-sealing process involves more refined treatment of the ceiling substrate, such as grinding, which better ensures the quality of the inner edge of the ceiling substrate, thus guaranteeing better quality, dimensions, and appearance of the edge sealing. However, the first edge-sealing process is complex and has a long process chain, requiring significant investment in materials, molds, tooling, and labor, resulting in high costs. Figure 6 As shown, the second edge-sealing process simplifies the treatment of the ceiling substrate, has a shorter process chain, and requires less tooling, molds, and manpower. However, the edge-sealing produced by the second process suffers from poorer quality, dimensions, and appearance, and its stability is also lower. Overall, existing edge-sealing solutions for ceiling skylight openings struggle to balance cost and quality.

[0003] like Figure 7 and Figure 8 As shown, part of the ceiling 4 uses a plastic reinforcing frame 5. The plastic reinforcing frame 5 is bonded to the ceiling substrate by adhesive. The edging 401 formed by the ceiling fabric covers the cut of the inner flange of the plastic reinforcing frame 5. The plastic reinforcing frame 5 is not suitable for hot stamping edging process.

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] like Figures 1 to 3The ceiling assembly shown includes a ceiling substrate 11 and a metal reinforcing frame 2. The ceiling substrate 11 includes a substrate body 111 with a skylight opening 3, a first flange 112 that flips upward from the edge of the skylight opening 3, a second flange 113 that flips outward from the upper edge of the first flange 112, and a third flange 114 that flips downward from the outer edge of the second flange 113. The metal reinforcing frame 2 includes a reinforcing frame body 21 that surrounds the periphery of the skylight opening 3 and a reinforcing frame flange 22 that flips upward from the inner edge of the reinforcing frame body 21. The reinforcing frame body 21 is connected to the upper side of the substrate body 111, the reinforcing frame flange 22 is connected to the outer side of the first flange 112, the second flange 113 is located on the upper side of the upper edge of the reinforcing frame flange 22, and the third flange 114 is connected to the outer side of the reinforcing frame flange 22.

[0021] By adopting the above technical solution and improving the structure of the ceiling assembly, a hot-stamping edge-wrapping device can be used to soften the substrate of the ceiling base plate 11 on the side near the skylight opening 3 and wrap it around the reinforcing frame flange 22 of the metal reinforcing frame 2. The dimensions of the metal reinforcing frame 2 are used to ensure the dimensions and appearance of the edge wrapping. The ceiling base plate 11 is thicker, and combined with the hot-stamping edge-wrapping process, the requirements for the metal reinforcing frame 2 can be reduced. This reduces the processing difficulty of the edge wrapping structure of the ceiling assembly while ensuring the quality of the edge wrapping structure.

[0022] The aforementioned metal reinforcing frame 2 provides stable support for the edging structure, ensuring the size and appearance of the edging structure, and also facilitates the use of hot stamping edging process.

[0023] In some embodiments, the reinforcing frame body 21 is glued to the substrate body 111, the reinforcing frame flange 22 is glued to the first flange 112, and the third flange 114 is glued to the reinforcing frame flange 22. This glued bonding ensures a strong connection between the ceiling substrate 11 and the metal reinforcing frame 2.

[0024] In some embodiments, the ceiling substrate 11 is a one-piece molded part. A hot stamping edge-wrapping process is used to enable the one-piece molded ceiling substrate 11 to form an edge-wrapping structure.

[0025] In some embodiments, the thickness of the third flange 114 is less than the thickness of the first flange 112, which helps to reduce the difficulty of implementing the edge binding and helps to ensure the coverage of the edge binding.

[0026] In some embodiments, the canopy assembly further includes a canopy fabric 12, which includes a first fabric portion 121 covering and connected to the lower side of the substrate body 111, a second fabric portion 122 covering and connected to the inner side of the first flange 112, a third fabric portion 123 covering and connected to the upper side of the second flange 113, and a fourth fabric portion 124 covering and connected to the outer side of the third flange 114. In specific implementations, such as... Figure 4As shown, the ceiling fabric 12 can be first bonded to the ceiling substrate 11 to form the ceiling body 1, and then the metal reinforcing frame 2 can be pressed onto the ceiling substrate 11. Then, the second flange 113 and the third flange 114 can be formed by hot stamping edge wrapping process, and the edge wrapping structure can be formed by the second flange 113 and the third flange 114.

[0027] In practice, in order to ensure the smoother formation of the second flange 113 and the third flange 114, the upper edge of the reinforcing frame flange 22 needs to be 1.5mm to 2.5mm lower than the upper side of the second flange 113.

[0028] In some embodiments, the reinforcing frame body 21 is provided with a plurality of upwardly arched protrusions 23, which are distributed sequentially at intervals along the circumference of the reinforcing frame body 21. Providing a plurality of protrusions 23 can improve the structural strength of the reinforcing frame body 21. Furthermore, providing protrusions 23 connected to the reinforcing frame flange 22 helps to maintain the relative position between the reinforcing frame body 21 and the reinforcing frame flange 22.

[0029] In some embodiments, an upwardly arched rib 24 is provided on the reinforcing frame body 21 at the portion between two adjacent protrusions 23, and the two ends of the rib 24 are respectively connected to the two adjacent protrusions 23. Providing the rib 24 can further improve the structural strength of the reinforcing frame body 21, and also help reduce the difficulty of matching the reinforcing frame body 21 with the ceiling substrate 11.

[0030] In some embodiments, the reinforcing frame body 21 has a plurality of through holes located between two adjacent protrusions 23. The through holes help to improve the bonding strength between the reinforcing frame body 21 and the ceiling substrate 11.

[0031] In some embodiments, the metal reinforcing frame 2 includes multiple metal frame segments connected end to end in sequence. Using multiple metal frame segments to construct the metal reinforcing frame 2 is easy to implement.

[0032] like Figure 4 As shown, after the roof substrate 11 is formed, the inner flange can be cut out, then the metal reinforcing frame 2 is press-fitted, and then adhesive can be sprayed onto the skylight area, followed by edge wrapping using a hot stamping machine. This application reorganizes two classic processes, combining their advantages to form a new process route. The roof component proposed in this application, combined with the hot stamping edge wrapping process, can balance quality and cost.

[0033] This utility model also proposes a vehicle including the roof assembly described in any of the above claims.

[0034] Vehicles can be, but are not limited to, Pure Electric Vehicles / Battery Electric Vehicles (PEVs / BEVs), Hybrid Electric Vehicles (HEVs), Range-Extended Electric Vehicles (REEVs), Plug-in Hybrid Electric Vehicles (PHEVs), New Energy Vehicles, and gasoline-powered vehicles.
