[0030] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a top cover assembly is provided.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the roof assembly includes a roof body 10 and a sunroof decorative cover 20. The roof body 10 has a sunroof opening. The sunroof decorative cover 20 is connected to the roof body 10 and is located on the side of the roof body 10 facing the interior of the driver's cab. At least a portion of the sunroof decorative cover 20 extends circumferentially along the sunroof opening. The sunroof decorative cover 20 and the roof body 10 enclose a receiving space 200. A reinforcing rib assembly 30 protrudes from the surface of the sunroof decorative cover 20 facing the receiving space 200. At least a portion of the reinforcing rib assemblies 30 form a guide channel 300, which is used to guide water accumulation inside the receiving space 200.

[0032] By applying the technical solution of this embodiment, a reinforcing rib assembly 30 is provided on the surface of the sunroof decorative cover 20 facing the receiving space 200, and a guide channel 300 is formed between the reinforcing rib assemblies 30. The guide channel 300 can guide the water accumulated inside the receiving space 200 to the drainage system. By providing the reinforcing rib assembly 30, the reinforcing rib assembly 30 not only maintains the original mechanical properties of the sunroof decorative cover 20, ensuring its strength and rigidity during vehicle use, but also achieves effective management of internal water flow through its structural layout, avoiding problems that may be caused by water stagnation in the receiving space 200. Similarly, by providing the reinforcing rib assembly 30, the thickness of the sunroof decorative cover 20 can be reduced without sacrificing overall performance, thereby significantly increasing the interior space of the driver's cab, thereby improving the riding comfort of the driver and passengers and the space utilization rate, solving the technical problem in the prior art where the large thickness of the sunroof decorative cover 20 leads to a reduction in the interior space of the driver's cab. In addition, due to the synergistic effect of the reinforcing rib assembly 30 and the guide channel 300, the need for additional components is reduced, the manufacturing process is simplified, and it helps to reduce production costs and improve assembly efficiency.

[0033] Specifically, the sunroof decorative cover 20 includes a cover body 21, which is connected to the roof body 10. The cover body 21 has a mesh opening 210 opposite to the sunroof opening. The cover body 21 extends circumferentially along the mesh opening 210. A flange structure 22 is formed near the mesh opening 210, and the cover body 21 is connected to the sunroof opening via the flange structure 22. The cover body 21 is directly mounted on the roof body 10 of the vehicle. The mesh opening 210 precisely corresponds to the sunroof opening on the roof body 10. The cover body 21 extends circumferentially along the mesh opening 210, forming a wraparound structure that better conforms to the contour of the roof body 10 and provides additional protection and support. A flange structure 22 is formed on the decorative cover body 21 near the mesh opening 210. Through the optimization of the flange structure 22, the decorative cover body 21 and the top cover body 10 are closely matched, which improves the sealing and aesthetics of the overall structure, facilitates positioning and adjustment during assembly, thereby simplifying the manufacturing process and reducing production costs.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, a dividing baffle 23 protrudes from the decorative cover body 21. The dividing baffle 23 extends circumferentially along the decorative cover body 21 and is positioned at a distance from the flange structure 22 and from the side of the decorative cover body 21, thus dividing the accommodating space 200 into a water-guiding inner cavity 201 and a reinforcing outer cavity 202. By rationally arranging the water-guiding inner cavity 201 and the reinforcing outer cavity 202, the necessary structural strength is maintained even with a reduced thickness of the decorative cover body 21, preventing deformation or damage during use. Furthermore, the introduction of the dividing baffle 23 optimizes the assembly between the decorative cover body 21 and the top cover body 10, reducing the risk of water leakage and improving the comfort and safety of the cab.

[0035] In one embodiment of this application, the specific shape and position of the dividing baffle 23 can be finely adjusted according to the size of the sunroof and the vehicle model requirements to achieve the best space utilization and structural reinforcement effect, realize the functional separation of the internal area of ​​the decorative cover body 21, ensure that the water flow is smoothly guided to the designated area, and enhance the overall rigidity of the decorative cover body 21.

[0036] Furthermore, such as Figure 3 and Figure 4As shown, the sunroof decorative cover 20 also includes a water guide 24. Along the length of the vehicle body, the water guide 24 is located at the front end of the decorative cover body 21. One end of the water guide 24 is connected to the water guide cavity 201, and the other end of the water guide 24 is connected to the external environment. The end of the water guide 24 away from the top cover body 10 is provided with a plurality of first reinforcing ribs 241. The plurality of first reinforcing ribs 241 are spaced apart along the width of the vehicle body to form a reinforcing rib groove 240. The opening of the reinforcing rib groove 240 is located on the side where the top cover body 10 is located. The side of the top cover body 10 facing the interior of the driver's cab is recessed inward to form a groove 11. The opening side of the groove 11 is opposite to the opening side of the reinforcing rib groove 240.

[0037] In this embodiment, a water guide 24 is provided at the front end of the decorative cover body 21, extending along the length of the vehicle body. The water guide 24 is connected to the water guide cavity 201 to guide rainwater collected from the sunroof area to discharge outward. Multiple first reinforcing ribs 241 are spaced apart along the width of the vehicle body, forming a series of reinforcing rib grooves 240. The openings of the grooves face the top cover body 10 to enhance the structural strength of the water guide 24 and its surrounding area. Furthermore, a groove 11 is formed on the side of the top cover body 10 facing the driver's cab, with its opening side opposite to the opening side of the reinforcing rib grooves 240. This not only optimizes the drainage path but also increases structural stability through the cooperation of the first reinforcing ribs 241 and the reinforcing rib grooves 240, preventing deformation of the water guide 24 during use and ensuring the waterproof performance of the sunroof area and the aesthetics of the driver's cab.

[0038] In one embodiment of this application, the form and distribution of the first reinforcing rib 241 can be adjusted according to the needs of a specific vehicle model to adapt to different vehicle body sizes and sunroof layouts, thereby further improving drainage efficiency and structural reliability.

[0039] Furthermore, the reinforcing rib assembly 30 includes a second reinforcing rib 31 and a third reinforcing rib 32. The second reinforcing rib 31 is disposed within the water guiding cavity 201 and is located on the side of the decorative cover body 21 near the mesh opening 210. The third reinforcing rib 32 is disposed within the water guiding cavity 201 and is connected to the dividing baffle 23. The third reinforcing rib 32 and the second reinforcing rib 31 are disposed opposite each other along the length of the vehicle body. There are multiple second reinforcing ribs 31 and multiple third reinforcing ribs 32. The multiple second reinforcing ribs 31 are spaced apart along the length of the vehicle body, and the multiple third reinforcing ribs 32 are spaced apart along the length of the vehicle body. Furthermore, adjacent second reinforcing ribs 31 and third reinforcing ribs 32 are spaced apart along the length of the vehicle body, so that a longitudinal flow channel 301 is formed between the second reinforcing ribs 31 and the third reinforcing ribs 32 in the flow channel 300.

[0040] In this embodiment, the reinforcing rib assembly 30 includes a second reinforcing rib 31 and a third reinforcing rib 32. The second reinforcing rib 31 is disposed on the side of the decorative cover body 21 near the mesh opening 210, located inside the water guiding cavity 201. The reinforcing rib assembly 30 is arranged along the length of the vehicle body, greatly enhancing the structural stability of the decorative cover body 21 and ensuring the necessary strength and rigidity. The third reinforcing rib 32 is also located within the water guiding cavity 201, connected to the dividing baffle 23, and is disposed opposite to the second reinforcing rib 31 along the length of the vehicle body. Both the second reinforcing rib 31 and the third reinforcing rib 32 are arranged in multiple intervals along the length of the vehicle body, ensuring uniform stress distribution throughout the entire decorative cover body 21. Adjacent second reinforcing ribs 31 and third reinforcing ribs 32 are spaced apart, forming a longitudinal flow channel 301 in between, enhancing the structural stability of the sunroof decorative cover 20, optimizing water flow guidance, achieving the dual goals of structural lightweighting and functional enhancement, thereby improving the utilization rate of the interior space of the cab and the user's comfort experience.

[0041] In one embodiment of this application, the shape and arrangement of the reinforcing rib assembly 30 can be varied to adapt to different structural requirements, providing strength support and water drainage. For example, a portion of the second reinforcing rib 31 and a portion of the third reinforcing rib 32 can extend along the length of the vehicle body, forming a funnel-shaped "Y"-shaped reinforcing rib structure. Accumulated water can flow from the larger end to the smaller end through the funnel-shaped "Y"-shaped structure to achieve better water drainage.

[0042] Specifically, the reinforcing rib assembly 30 also includes a fourth reinforcing rib 33, which is disposed on the side of the decorative cover body 21 away from the water inlet 24. The fourth reinforcing rib 33 extends along the length of the vehicle body and connects to the flange structure 22. There are multiple fourth reinforcing ribs 33, which are spaced apart along the width of the vehicle body. The spaced arrangement of multiple fourth reinforcing ribs 33 along the width of the vehicle body not only increases the lateral strength of the decorative cover body 21, but also improves its bending and torsional resistance. By distributing the load, the pressure on individual components is reduced, thereby enhancing the stability of the entire structure.

[0043] Specifically, at least one break is provided on the fourth reinforcing rib 33, and the breaks of multiple fourth reinforcing ribs 33 are arranged opposite each other along the width direction of the vehicle body to form a transverse guide channel 302 in the guide channel 300 between the multiple fourth reinforcing ribs 33. At least a portion of the transverse guide channel 302 extends along the width direction of the vehicle body. By providing breaks on the fourth reinforcing ribs 33 to form transverse guide channels 302, water flow can be evenly dispersed along the width direction of the vehicle body, reducing the possibility of local water accumulation, thereby improving the waterproof performance and driving comfort of the interior of the cab. While ensuring the overall strength and rigidity of the sunroof decorative cover 20, it achieves ultra-thinness, providing more space for the interior of the cab and optimizing the spatial layout.

[0044] In one embodiment of this application, the shape and position of the fracture can be adjusted according to actual needs to adapt to different drainage requirements and reinforcing rib layouts, further improving the flexibility and practicality of the design.

[0045] Furthermore, the reinforcing rib assembly 30 also includes a fifth reinforcing rib 34, which is located on the side of the decorative cover body 21 away from the water inlet 24. The fifth reinforcing rib 34 extends along the width direction of the vehicle body and is connected to multiple fourth reinforcing ribs 33. The break in the fourth reinforcing rib 33 is located on one side of the fifth reinforcing rib 34. The fifth reinforcing rib 34, located along the width direction of the vehicle body and connected to multiple fourth reinforcing ribs 33, enhances the longitudinal rigidity of the decorative cover body 21. The break in the fourth reinforcing rib 33 effectively guides water flow, promoting smooth drainage of rainwater. The connection between the fifth reinforcing rib 34 and the fourth reinforcing ribs 33 forms a stable spatial frame, ensuring the structural strength of the decorative cover and preventing deformation or damage during use. In addition, the break in the fifth reinforcing rib 34 allows accumulated water to accumulate at the break through the stop of the fifth reinforcing rib 34, facilitating the flow of accumulated water along the transverse guide channel 302 and improving the flow speed and efficiency of accumulated water.

[0046] Specifically, the reinforcing rib assembly 30 also includes a sixth reinforcing rib 35, which is disposed within the reinforcing outer cavity 202. Multiple sixth reinforcing ribs 35 are present, some forming an annular reinforcing structure 350, and others connected to the annular reinforcing structure 350. At least one of the sixth reinforcing ribs 35 and the annular reinforcing structure 350 is connected to the outer side of the dividing baffle 23 and the decorative cover body 21. By increasing the internal support structure of the sunroof decorative cover 20, the overall rigidity and strength of the sunroof decorative cover 20 are enhanced. The annular reinforcing structure 350 provides more uniform structural support for the sunroof decorative cover 20, effectively avoiding local stress concentration, thereby improving the stability and service life of the decorative cover. The sixth reinforcing rib 35 connects with the annular reinforcing structure 350 to form a mesh reinforcing structure, which can further improve the structural strength of the sunroof decorative cover 20. After reducing the thickness of the sunroof decorative cover 20, it can be ensured that the strength of the sunroof decorative cover 20 meets the requirements, thereby reducing the space occupied by the sunroof decorative cover 20 in the driver's cab.

[0047] In one embodiment of this application, the shape and layout of the sixth reinforcing rib 35 can be adjusted according to actual needs to adapt to different skylight structures and decorative effects, demonstrating greater design flexibility and practicality.

[0048] According to another specific embodiment of this application, a vehicle is also provided, which has a commercial vehicle roof assembly, the commercial vehicle roof assembly being the same as that in the above embodiments. Applying the roof assembly from the above embodiments to a commercial vehicle, the roof assembly, through the decoration of the roof body 10 and the sunroof trim cover 20, can maintain good performance while reducing the thickness of the sunroof trim cover 20, increasing the usable space in the cab, and thus improving the comfort of the cab.

[0049] This application also provides a preferred embodiment of a commercial vehicle roof assembly.

[0050] Specifically, the skylight decorative cover 20 includes a decorative cover body 21, decorative buckles, and an insect-proof net pull rod. The internal structure consists of an insect-proof net slide rail and an insect-proof net roll.

[0051] The sunroof decorative cover 20 is fitted onto the sunroof and works in conjunction with the headliner to maximize the interior space of the driver's cabin. Figure 5As shown, the overall thickness L1 of the sunroof trim cover 20 is approximately 30 mm, and the basic thickness L2 is approximately 15 mm. A reinforcing rib assembly 30 and a water guiding structure are provided inside. Among them, the connected and continuous annular reinforcing structure 350, the "Y"-shaped reinforcing ribs, and the "field"-shaped reinforcing ribs can increase or decrease the stiffness and strength of the sunroof trim cover 20, which is equivalent to the strength of the sunroof trim cover 20 with a large overall thickness. At the same time, a diversion channel 300 is formed between the reinforcing rib assemblies 30, which can guide the water flow direction in the accommodation space 200 and direct the accumulated water to the water outlet 24.

[0052] Due to the requirement of the ultra-thin thickness of the sunroof trim cover 20, the "U"-shaped reinforcing rib design symmetrically distributed at the water outlet 24 can enhance the strength of the water outlet 24 and meet the strength requirements of the sunroof trim cover 20.

[0053] It can be seen from the above description that the roof assembly in the above embodiments has the following beneficial effects:

[0054] 1) Space optimization: By reducing the thickness of the sunroof trim cover 20 and adopting the reinforcing rib assembly 30, the maximum utilization of the interior space of the cab is achieved, and the driving comfort is improved.

[0055] 2) Structural strength and stiffness: The sunroof trim cover 20 forms a "field"-shaped structure surrounded by the continuous annular reinforcing structure 350, the "Y"-shaped reinforcing ribs, the fourth reinforcing rib 33, and the fifth reinforcing rib 34. Under the premise of ensuring that the structural strength and rigidity are not affected, the light weight of the sunroof trim cover 20 is achieved, and at the same time, it plays a role in fixing the interior arc surface.

[0056] 3) Water guiding function: A diversion channel 300 is formed between the reinforcing rib assemblies 30, and guiding breaks beneficial to water flow are provided on some of the reinforcing rib assemblies 30, ensuring that the sunroof trim cover 20 can still maintain good water guiding performance while reducing the thickness, avoiding rainwater accumulation inside the trim cover, and further improving the comfort and safety of the cab.

[0057] 4) Cost effectiveness: The optimized sunroof trim cover 20 reduces the use of materials, reduces the production cost while maintaining the required structural performance and functionality.

[0058] 5) Emphasis on aesthetics and functionality: The connection between the flanging structure 22 of the sunroof trim cover 20 and the roof body 10 not only provides a stable installation method but also ensures the cleanliness and beauty of the appearance.

[0059] 6) Durability and maintenance convenience: The double "U"-shaped structure design is adopted at the water outlet 24. While minimizing the thickness of the water outlet 24, it ensures the strength and stiffness of the water outlet 24 and at the same time plays a role in supporting the protective surface.
