Description

Technical Field

[0001] The utility model belongs to the technical field of automobile bodies, and specifically relates to an automobile skylight roof reinforcement structure. Background Art

[0002] In recent years, customers have increasingly demanded higher levels of vehicle comfort, with a growing focus on road noise levels. Excellent road noise performance directly impacts customer perception of a vehicle, leading to increasing NVH standards in the early stages of development. The vehicle's bending and torsional modes, as well as the modal levels of large panels, are crucial for their impact on road noise. These large panel modes include the dash panel, front and rear floor modes, roof modes, and side panel modes.

[0003] As customers' aesthetic tastes for cars improve and the automotive industry keeps pace with the times, many automakers are adding skylight roofs to meet these demands, improving daylighting and adding a touch of style. However, compared to traditional sheet metal roofs, skylight roofs have lower modal characteristics, significantly impacting the vehicle's road noise performance. Therefore, improving the roof's modal characteristics can positively impact the vehicle's overall road noise performance, enhancing NVH performance and ultimately increasing its market competitiveness.

[0004] Existing technologies lack effective solutions for improving the NVH performance of roof assemblies. Laminated glass is primarily used to replace traditional glass, but this improvement has limited effectiveness. Because the skylight roof requires sufficient daylighting and the limited interior space of the vehicle, the vehicle's roof design must be simple, which increases the difficulty of improving the roof's modal response. Considering both quality and cost, improving the roof's modal response is even more challenging.

[0005] A utility model patent, publication number CN219406121U, published on July 25, 2023, discloses a panoramic sunroof structure comprising sunroof glass and a roof frame. The roof frame comprises a front crossbeam assembly, a left side panel assembly, a rear crossbeam assembly, and a right side panel assembly, all connected in sequence. The front of the sunroof glass is connected to the front crossbeam assembly, the left side panel assembly is connected to the left side panel assembly, the rear of the sunroof glass is connected to the rear crossbeam assembly, and the right side panel assembly is connected to the right side panel assembly. This panoramic sunroof structure also fails to resolve the aforementioned technical issues. Utility Model Content

[0023] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0024] like Figures 1 to 4 As shown, the automobile sunroof reinforcement structure includes a top cover 1, on which a reinforcement bracket 2 is provided. The reinforcement bracket 2 includes a first reinforcement bracket 3 and a second reinforcement bracket 4. The first reinforcement bracket 3 is provided with a glue groove 5 at both ends, and the second reinforcement bracket 4 is provided with side panel mounting holes 6 on both sides. The first reinforcement bracket 3 is located at both ends of the reinforcement bracket 2, supporting the sunroof front and back. The second reinforcement bracket 4 is located on both sides of the reinforcement bracket 2, supporting the sunroof left and right and forming a connection with the vehicle body side panel. A sunroof reinforcement system is formed by the first reinforcement bracket 3 and the second reinforcement bracket 4, which improves the NVH performance of the sunroof assembly. At the same time, the reinforcement bracket 2 is an integral part, which has an overall reinforcement effect on the sunroof structure. Its structure is simple, which can achieve development with fewer parts and improve production efficiency. It not only reduces cost and weight, but also improves the NVH performance of the sunroof structure and the entire vehicle.

[0025] like Figure 1 and Figure 4 As shown, the reinforcement bracket 2 has a square structure and is equipped with a sunken boss 7. Located in the middle of the reinforcement bracket 2's cross-section, the sunken boss 7 alters the reinforcement bracket 2's cross-section, creating a "F"-shaped structure. This improves the reinforcement bracket 2's load-bearing capacity and significantly enhances the ceiling's modal properties. The distribution of the sunken bosses 7 matches the shape of the reinforcement bracket 2, forming a square structure that strengthens the entire reinforcement bracket 2 and effectively improves the overall modal properties of the ceiling.

[0026] like Figure 3 As shown, a roof support bracket 8 is provided at the bottom of the middle portion of the second reinforcing bracket 4. The roof support bracket 8 supports the middle portions of both sides of the roof, which is beneficial to improving the roof modality.

[0027] like Figure 1As shown, the glue grooves 5 are arranged at equal intervals, and the glue grooves 5 are in a strip-shaped structure. The glue grooves 5 located at both ends of the first reinforcing bracket 3 are bent into an arc shape. Multiple glue grooves 5 allow the reinforcing bracket 2 and the top cover 1 to overlap more area, which not only improves the roof mode, but also improves the bending mode of the body-in-white. The setting of the glue grooves 5 forms a reinforcing rib structure on the reinforcing bracket 2, further improving the structural strength. The arc-shaped glue grooves 5 at both ends of the first reinforcing bracket 3 are conducive to forming a planar overlap with the top cover 1, improving the reliability of the bonding. A plurality of side mounting holes 6 are also provided, and the local mode of the roof and the bending and torsional mode of the body-in-white can also be improved.

[0028] like Figure 4 As shown, the second reinforcement bracket 4 has a raised structure at the edge of the side panel mounting hole 6. The raised structure on the sheet metal at the edge of the side panel mounting hole 6 facilitates the distribution of the bolt connection force and also has a limiting effect on the bolt, ensuring the reliability of the connection between the reinforcement bracket 2 and the side panel.

[0029] like Figure 1 As shown, the second reinforcing bracket 4 is provided with reinforcing ribs 10 on its edge, located between the side panel mounting holes 6. This structure fully utilizes the edge area of ​​the reinforcing bracket 2. The reinforcing ribs 10, combined with the adhesive grooves 5 on the first reinforcing bracket 3, provide uniform structural reinforcement for the entire reinforcing bracket 2, thereby improving the sheet metal strength.

[0030] like Figure 1 and Figure 2 As shown, the reinforcement bracket 2 is a symmetrical structure. The symmetrical design reduces the difficulty of sheet metal stamping, helps reduce production costs, and achieves standardized development.

[0031] like Figure 4 As shown, a weight-reducing hole 11 is provided on the sunken boss 7. The weight-reducing hole 11 is provided in the area of ​​the sunken boss 7, making full use of the sheet metal area of ​​the reinforcing bracket 2. The weight-reducing hole 11 further reduces the overall sheet metal weight of the reinforcing bracket 2, which conforms to the lightweight design of automobile parts.

[0032] This automotive sunroof reinforcement structure features an integrated reinforcement bracket 2, with features such as a lower glue groove 5, side panel mounting holes 6, a countersunk boss, and a roof support bracket 8 incorporated into the bracket. This provides reliable reinforcement for the sunroof structure, reduces cost and weight, and improves both the sunroof modal and body-in-white bending modes. This reduces the risk of vibration, squeaks, and noise from engine and road excitation, improving the sunroof's resilience and overall vehicle NVH performance. Testing has shown a 15% improvement in roof modal performance and a 5% improvement in body-in-white bending modes.
