[0001] The present invention relates to the field of vehicles and provides a roof structure, a vehicle body and a vehicle. Background Art

[0002] In the prior art, roof equipment is often mounted by welding mounting brackets to the roof. When there are numerous mounting brackets, maintaining consistent dimensional tolerances between them is challenging. Furthermore, to enhance the roof's structural strength, pads are added to the lower flanges of the curved beams within the roof, and C-shaped guide rails are welded for equipment suspension. This significant welding effort increases the weight of the roof. The roof is tightly fitted to the side and end walls, leaving no margin for adjustment and hindering control over the vehicle's dimensions after assembly. Summary of the Invention

[0003] An embodiment of the present invention provides a roof structure to solve the defect in the related art that the roof and the side walls and end walls cannot be adjusted, thereby realizing adjustable installation of the roof.

[0021] A second embodiment of the present invention provides a vehicle body comprising side walls, an underframe, and the roof structure as described above;

[0022] Along the circumferential direction of the vehicle, the roof curved beam, the side walls and the underframe are arranged to form a closed-loop bearing structure.

[0023] A third embodiment of the present invention provides a vehicle, comprising the roof structure as described above, or the vehicle body as described above.

[0024] According to the first embodiment of the present invention, a roof structure is provided in which a first sliding portion and a second sliding portion are provided on the roof side rails, enabling the roof side rails to slide relative to the side walls and end walls in the longitudinal and width directions, respectively. This design greatly enhances the flexibility of the roof structure, enabling it to adapt to different vehicle models, sizes, and design requirements, while also facilitating installation and adjustment during vehicle manufacturing. The roof bow, a key component connecting the roof side rails, securely connects its ends between a pair of roof side rails, forming a stable support structure. This structure not only enhances the rigidity and strength of the roof but also provides effective protection against rollovers or collisions, minimizing deformation within the vehicle cabin and thus protecting passengers.

Furthermore, the increased rigidity of the roof structure contributes to improved sound insulation, providing passengers with a quieter and more comfortable ride.

[0025] According to the second aspect of the present invention, the vehicle body provided by the embodiment features a closed-loop load-bearing structure formed by the roof arch, side walls, and underframe circumferentially arranged around the vehicle, significantly enhancing the overall strength and rigidity of the vehicle body. This closed-loop design allows the vehicle body to more effectively disperse and absorb energy when subjected to external impacts or loads, thereby protecting the vehicle and passengers. The closed-loop load-bearing structure not only enhances the strength of the vehicle body but also improves its stability. Whether driving at high speeds or in complex road conditions, the vehicle body maintains a stable position, reducing passenger discomfort caused by vibration or bumps. The roof structure design allows for flexible adjustment based on actual needs, thereby optimizing the interior space layout of the vehicle body. The closed-loop load-bearing structure helps improve the sealing and sound insulation of the vehicle body. The tight connection between the roof arch, side walls, and underframe reduces the intrusion of external noise and dust, providing passengers with a quieter and more comfortable riding environment. The modular design of the roof structure, side walls, and underframe simplifies the vehicle body manufacturing process. Each component can be independently manufactured and tested, and then quickly assembled on the final assembly line, improving production efficiency and product quality. The robust closed-loop load-bearing structure provides enhanced durability, enabling it to withstand prolonged use and harsh environments. The modular design also facilitates component replacement and repair during vehicle maintenance, reducing maintenance costs and time.

[0026] The vehicle provided by the third embodiment of the present invention, whether employing the aforementioned roof structure or vehicle body, achieves enhanced structural strength and stability due to its closed-loop load-bearing structure design.

[0034] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0035] like Figures 1 to 4 As shown, an embodiment of the first aspect of the present invention provides a roof structure, including a pair of roof side beams 100 and a roof curved beam 110; the pair of roof side beams 100 are provided with a first sliding portion 102 along the length direction of the roof side beams 100, and a second sliding portion 104 is provided at the end of the roof side beam 100 along the width direction of the roof side beam 100, the roof side beam 100 is suitable for being slidably connected to the side wall 106 through the first sliding portion 102, and the roof side beam 100 is suitable for being slidably connected to the end wall 108 through the second sliding portion 104; the two ends of the roof curved beam 110 are connected between the pair of roof side beams 100.

[0036] According to the first embodiment of the present invention, the roof structure provided by the first sliding portion 102 and the second sliding portion 104 on the roof side rail 100 enables sliding connection with respect to the side wall 106 and the end wall 108 along the length and width directions, respectively. This design greatly enhances the flexibility of the roof structure, enabling it to adapt to different vehicle models, sizes, and design requirements, while also facilitating installation and adjustment during vehicle manufacturing. The roof bow 110, a key component connecting the roof side rails 100, is securely connected at both ends between the pair of roof side rails 100, forming a stable support structure. This structure not only enhances the rigidity and strength of the roof but also provides effective protection against rollovers or collisions, minimizing deformation within the vehicle cabin and thus protecting passengers. Because the design of the roof side rails 100 and roof bow 110 allows for sliding adjustment within a certain range, precise layout can be achieved based on the actual needs of the vehicle interior. This design helps optimize vehicle interior space utilization, providing a more spacious and comfortable riding or loading environment for passengers and cargo. The modular design of the roof structure allows each component to be manufactured and transported independently, and then quickly assembled on the vehicle assembly line. This production method not only improves production efficiency but also reduces manufacturing costs. Furthermore, because the connections between the components are sliding, the assembly process is simpler and faster, reducing assembly errors and rework. Precisely controlled sliding connections between the roof side rails 100 and the side and end walls 106 and 108 ensure a tight seal between the roof and the vehicle body, preventing external factors such as rain and dust from entering the vehicle interior. Furthermore, the increased rigidity of the roof structure also helps improve the vehicle's sound insulation, providing passengers with a quieter and more comfortable riding environment.

[0037] Please continue to see Figures 1 to 4 The roof structure provided in the embodiment of the first aspect of the present invention is intended to enhance the structural flexibility and load-bearing capacity of the vehicle roof through innovative design.

[0038] The roof structure includes a pair of roof rails 100 extending along the length of the roof. Each roof rail 100 is provided with a first sliding portion 102 along its length, which allows for a slidable connection between the roof rail 100 and a side wall 106. Furthermore, second sliding portions 104 are provided at the ends of the roof rail 100 along its width, which allow for a slidable connection between the roof rail 100 and an end wall 108.

[0039] The roof bow 110 is a key connecting component, with its two ends firmly connected between a pair of roof side rails 100. This connection method ensures the stability and integrity of the roof structure.

[0040] By configuring the first sliding portion 102 and the second sliding portion 104, the roof rail 100 can be fine-tuned in length and width when needed to accommodate different vehicle sizes or installation requirements. This sliding connection mechanism not only increases installation flexibility but also helps reduce assembly errors.

[0041] In this embodiment of the present invention, the sliding connection mechanism enables flexible adjustment and installation of the roof structure based on actual needs, increasing the diversity and adaptability of vehicle design. The secure connection between the roof bow 110 and the roof side rails 100 ensures the overall strength of the roof structure, enabling it to withstand greater external loads and impacts. The sliding connection design simplifies the assembly process, reducing assembly time and costs. It also helps improve assembly accuracy and reduce problems caused by assembly errors.

[0042] In the embodiment of the present invention, while maintaining the sliding connection mechanism, an adjustable sliding portion can be further designed. These sliding portions can achieve fine-tuning functions through threads, slots, or other adjustable structures, so as to more accurately adjust the position and angle of the roof rail 100.

[0043] Components such as the roof side rails 100 and roof bow 110 are designed as modular components, allowing them to be independently manufactured, tested, and replaced. This design not only improves production efficiency and quality but also facilitates future maintenance and upgrades. To further enhance the load-bearing capacity of the roof structure, a more reinforced structural design can be employed at the connections between the roof side rails 100 and the side walls 106, end walls 108, and roof bow 110. For example, reinforcing plates, ribs, or special connectors can be used to increase the strength and rigidity of these connections. The roof structure can be integrated with other vehicle systems (such as the air conditioning system and ventilation system). This design can reduce the complexity and weight of the roof structure while improving the overall performance and efficiency of the system. While ensuring strength and rigidity, lightweight materials (such as composite materials) can be considered for components such as the roof side rails 100 and roof bow 110. This helps reduce the overall weight of the vehicle, improving fuel economy and environmental performance.

[0044] According to one embodiment of the present invention, the first sliding portion 102 includes a first mounting plate 112, a first connecting plate 114 and a first bent plate 116; the first mounting plate 112 is mounted on the roof side rail 100; the first connecting plate 114 is connected to the side wall 106; the first bent plate 116 is connected between the first mounting plate 112 and the first connecting plate 114 and at least a portion of the first bent plate 116 is connected to the side wall 106.

[0045] like Figure 3As shown, in one embodiment of the present invention, the design of the first sliding portion 102 further refines the connection structure between the roof rail 100 and the side wall 106, specifically including three main components: a first mounting plate 112, a first connecting plate 114, and a first bent plate 116. This design not only enhances the stability of the connection, but also improves the smoothness of sliding and the flexibility of adjustment.

[0046] The first mounting plate 112 is securely mounted on the roof side rail 100, typically by welding, bolting, or other fastening methods. Its position should ensure that it matches the structural strength of the roof side rail 100 and can effectively transfer loads.

[0047] The first connecting plate 114 is directly connected to the side wall 106 and is a key component for transmitting force and displacement between the roof rail 100 and the side wall 106. It typically mates with corresponding structures on the side wall 106 (such as slide rails, mounting brackets, etc.) to achieve a slidable connection. The first connecting plate 114 not only connects the roof rail 100 to the side wall 106 but also, through its structural design, guides the sliding direction of the roof rail 100, ensuring accurate and stable sliding.

[0048] The first bent plate 116 is cleverly connected between the first mounting plate 112 and the first connecting plate 114 to form a sliding connection bridge. Its design takes into account the smoothness of sliding and the compactness of the structure, ensuring that there will be no excessive resistance and interference during the sliding process.

[0049] Notably, at least a portion of first bent plate 116 is connected to side wall 106. This design enhances the stability and reliability of the sliding connection, allowing roof rail 100 to better conform to the surface of side wall 106 during sliding, reducing shaking and noise. First bent plate 116 not only transfers force and displacement between roof rail 100 and side wall 106 but also, through its curved shape, accommodates deformation and displacement during sliding, ensuring the durability and longevity of the sliding connection.

[0050] Through the coordinated action of the first mounting plate 112, the first connecting plate 114, and the first bent plate 116, the first sliding portion 102 securely connects the roof rail 100 to the side wall 106. This connection structure can withstand significant forces and displacements, ensuring the stability and safety of the roof structure during driving.

[0051] Improved Sliding Smoothness: The design of the first bent plate 116 takes into account smooth sliding, reducing resistance and interference during the sliding process. This allows the roof rail 100 to slide easily on the side wall 106, meeting the fine-tuning requirements during vehicle manufacturing and installation.

[0052] Since the first sliding portion 102 is slidably connected, the roof rail 100 can be flexibly adjusted according to actual needs. This flexibility not only increases the diversity of vehicle designs, but also facilitates rapid adjustment and correction during manufacturing and installation.

[0053] The compact design of the first sliding portion 102 reduces the overall size and weight of the roof structure, helping to improve the vehicle's fuel economy and environmental performance. At the same time, the compact structural design also makes the roof structure more beautiful and coordinated.

[0054] According to one embodiment of the present invention, the second sliding portion 104 includes a second mounting plate 118, a second connecting plate 120 and a second bent plate 122; the second mounting plate 118 is installed on the roof bending beam 110; the second connecting plate 120 and the second bent plate 122 are connected to each other, the second connecting plate 120 and the second bent plate 122 are connected to the end wall 108, and the second bent plate 122 is connected between the second mounting plate 118 and the second connecting plate 120.

[0055] like Figure 4 As shown, in one embodiment of the present invention, the design of the second sliding portion 104 further refines the connection structure between the roof side rail 100 (indirectly connected via the roof bow 110) and the end wall 108. This design ensures the flexibility and stability of the roof structure in the vehicle length direction.

[0056] The second mounting plate 118 is mounted on the roof bow 110 and serves as a key component connecting the roof bow 110 to the end wall 108. It is typically securely fastened to the roof bow 110 via welding, bolting, or other fastening methods. The second mounting plate 118 provides a stable support base for the second sliding portion 104, further enhancing the reliability of the connection between the roof bow 110 and the end wall 108.

[0057] The second connecting plate 120 is connected to the end wall 108 and directly transmits force and displacement between the roof bow 110 and the end wall 108. It typically mates with corresponding structures on the end wall 108 (such as mounting brackets, slide rails, etc.) to achieve a slidable connection. The second connecting plate 120 not only connects the roof bow 110 to the end wall 108 but also guides the sliding direction of the roof bow 110 relative to the end wall 108 through its structural design (such as sliding grooves and guide slots), ensuring accurate and stable sliding.

[0058] The second bent plate 122 is connected between the second mounting plate 118 and the second connecting plate 120, forming a bridge for the sliding connection. Its design takes into account the smoothness of sliding and the compactness of the structure, ensuring that no excessive resistance and interference will be generated during the sliding process. The second bent plate 122 is not only connected to the second mounting plate 118 and the second connecting plate 120, but also directly connected to the end wall 108. This design enhances the stability and reliability of the sliding connection. It enables the roof curved beam 110 to better fit the surface of the end wall 108 during the sliding process, reducing shaking and noise. The second bent plate 122 adapts to deformation and displacement during the sliding process through its bent shape, ensuring the durability and durability of the sliding connection. At the same time, it also transmits the force and displacement between the roof curved beam 110 and the end wall 108, so that the entire roof structure remains coordinated in the length direction of the vehicle.

[0059] The second sliding portion 104, through the coordinated action of the second mounting plate 118, the second connecting plate 120, and the second bent plate 122, securely connects the roof bow 110 to the end wall 108. This connection structure can withstand the various forces and displacements generated during vehicle operation, ensuring the stability and safety of the roof structure. The design of the second bent plate 122 optimizes the mechanical properties during sliding, reducing sliding resistance and interference. This allows the roof bow 110 to slide easily on the end wall 108, meeting the fine-tuning requirements during vehicle manufacturing and installation. Because the second sliding portion 104 utilizes a slidable connection, the roof bow 110 can be flexibly adjusted according to actual needs. This adjustable flexibility enhances the diversity and adaptability of vehicle design, allowing the roof structure to better adapt to the needs of different vehicle models and configurations. The compact design of the second sliding portion 104 reduces the overall size and weight of the roof structure, helping to improve the vehicle's fuel economy and environmental performance. Furthermore, the compact design makes the roof structure more aesthetically pleasing and coordinated, enhancing the overall quality of the vehicle.

[0060] According to one embodiment of the present invention, a hanging component 124 is pre-embedded on the roof bow 110 , and the hanging component 124 is used to install in-vehicle equipment.

[0061] like Figure 2 As shown, in one embodiment of the present invention, the design of the roof bow 110 is further optimized, particularly in terms of its functionality. Specifically, a hanging component 124 is pre-embedded in the roof bow 110. This design innovation not only enhances the practicality of the roof structure but also facilitates the installation and maintenance of in-vehicle equipment.

[0062] The slings 124 are pre-embedded in appropriate locations inside or outside the roof arch 110. These locations are selected based on the mechanical properties of the roof arch 110 and the installation requirements of the in-vehicle equipment to ensure the stability and efficiency of the slings 124. The slings 124 can adopt a variety of structural forms, such as bolt holes, eyelets, hooks, rivets, etc., to facilitate connection with different types of in-vehicle equipment. These slings 124 typically have sufficient strength and rigidity to withstand the weight of the in-vehicle equipment and the dynamic loads during operation.

[0063] Through the pre-embedded hanging parts 124 on the roof curved beam 110, the in-vehicle equipment can be installed to the designated location more conveniently. There is no need to perform complicated drilling or welding operations on the top of the vehicle, which greatly reduces the difficulty and time cost of installation. The stable connection between the hanging parts 124 and the roof curved beam 110 ensures the stability of the in-vehicle equipment after installation. This stability is of great significance to ensuring the normal operation of the equipment and extending its service life. When the in-vehicle equipment needs maintenance or replacement, the hanging parts 124 can be used to facilitate disassembly and installation. This design reduces the workload and time cost of maintenance personnel and improves maintenance efficiency. The design of the hanging parts 124 also takes into account safety during the maintenance process. They usually have anti-slip and anti-loosening properties to prevent accidents during disassembly and installation.

[0064] The embedded hanging parts 124 on the roof arch 110 ensure that the roof structure not only has a supporting and connecting function, but also has the function of installing in-vehicle equipment. This design greatly enhances the practicality of the roof structure and meets the diverse needs of vehicle interior space layout and equipment installation. The embedded design of the hanging parts 124 simplifies the installation process of in-vehicle equipment and improves installation efficiency. This not only shortens the vehicle manufacturing cycle but also reduces manufacturing costs. The stable connection between the hanging parts 124 and the roof arch 110 ensures the stability and safety of the in-vehicle equipment after installation. This design helps to extend the service life of the equipment and reduce safety hazards caused by loose or falling equipment. The design of the hanging parts 124 also takes into account the maintenance and replacement needs of in-vehicle equipment. They make it easier for maintenance personnel to perform disassembly and installation work, improving maintenance efficiency and reducing maintenance costs.

[0065] According to one embodiment of the present invention, a corrugated plate 126 is laid on the roof side rail 100 , and a roof mounting seat 128 is provided on a side of the corrugated plate 126 facing away from the roof side rail 100 along the length direction of the roof side rail 100 .

[0066] like Figure 1 As shown, in one embodiment of the present invention, the design of the roof side rail 100 is further improved by laying a corrugated sheet 126 thereon and providing a roof mounting seat 128 , thereby enhancing the strength and functionality of the roof structure.

[0067] The corrugated sheet 126 is typically made of a lightweight, high-strength metal material, such as aluminum alloy or stainless steel. These materials not only offer excellent corrosion resistance but also effectively reduce the weight of the roof structure. The corrugated sheet 126 is laid along the length of the roof rail 100 and fits snugly against it. Welding, bolting, or other fastening methods ensure a secure connection between the corrugated sheet 126 and the roof rail 100.

[0068] The design of the corrugated plate 126 increases the rigidity and strength of the roof rail 100, enabling it to better withstand the various forces and loads generated during vehicle operation. At the same time, the corrugated plate 126 also has certain sound insulation and heat insulation effects, improving the riding comfort in the vehicle.

[0069] Roof mounts 128 are located on the side of the corrugated plate 126 facing away from the roof rail 100, that is, the side facing the interior of the roof. This arrangement facilitates the installation and securing of various devices within the vehicle. Roof mounts 128 are typically made of durable materials such as cast iron or steel. They possess sufficient strength and rigidity to withstand the weight of the mounted equipment and the dynamic loads during operation. The design of roof mounts 128 also takes into account the connection method with the corrugated plate 126 and the selection of fasteners to ensure a secure and reliable installation.

[0070] Roof mount 128 provides a convenient interface and support point for in-vehicle device installation. Roof mount 128 facilitates the installation of various roof accessories. These devices not only enhance the functionality and practicality of the vehicle, but also add to its aesthetic and technological appeal.

[0071] The installation of corrugated sheeting 126 significantly enhances the rigidity and strength of roof side rails 100, enabling them to better withstand various forces and loads. This helps improve the overall structural safety and stability of the vehicle. Corrugated sheeting 126 provides a certain degree of sound and heat insulation, reducing the impact of external noise and temperature on the interior environment of the vehicle and enhancing ride comfort. The provision of roof mounts 128 provides a convenient interface and support point for the installation of in-vehicle equipment. Roof mounts 128 facilitate the installation of various roof accessories to meet the diverse needs of users. The design of roof mounts 128 allows the vehicle to be equipped with a wider range of roof accessories, thereby enhancing the vehicle's functionality and practicality. These accessories not only enhance the vehicle's aesthetic and technological appearance, but also provide users with greater convenience and enjoyment.

[0072] According to one embodiment of the present invention, there are multiple roof mounting seats 128 along the length direction of the roof side rail 100, at least one of two adjacent roof mounting seats 128 is provided with a mounting interface 130, and the top of the roof mounting seat 128 is also provided with a long mounting hole 132.

[0073] like Figure 1 As shown, in a specific embodiment of the present invention, the design of the roof mounting seat 128 is further refined and optimized to meet a wider range of installation requirements and higher flexibility.

[0074] A plurality of roof mounting brackets 128 are provided along the length of the roof side rail 100. This design allows for more mounting points to be distributed on the roof side rail 100, thereby supporting more diverse roof accessory mounting requirements.

[0075] The specific number and distribution position of the roof mounting brackets 128 can be flexibly adjusted according to the actual needs of the vehicle. For example, in an area where a large roof accessory needs to be installed, the number of roof mounting brackets 128 can be increased to ensure the stability of the installation.

[0076] At least one of two adjacent roof mounts 128 is provided with a mounting interface 130 for connecting to corresponding components on the roof accessory. In this embodiment of the present invention, mounting interface 130 may be a beveled structure. The provision of mounting interface 130 facilitates and flexibly installs the roof accessory. The user can select the appropriate mounting interface 130 as needed and use the appropriate fasteners to securely attach the roof accessory to the roof mount 128 through the mounting interface 130.

[0077] A long mounting hole 132 is further provided on the top of the roof mounting seat 128. The long mounting hole 132 is a long strip-shaped hole, and its length direction is usually consistent with the length direction of the roof side rail 100.

[0078] The design of the slotted mounting hole 132 provides greater adjustment space for installation. Based on the specific size and installation location of the roof accessory, the user can select the appropriate mounting point within the slotted hole 132 and secure it with fasteners. This design makes the installation of the roof accessory more precise and reliable.

[0079] The provision of multiple roof mounts 128 and mounting interfaces 130, along with the design of the elongated mounting holes 132, allows for greater flexibility and versatility in the installation of roof accessories. Users can choose the appropriate mounting location and method to meet their specific needs. The rational number and distribution of roof mounts 128, as well as the design of the mounting interfaces 130 and elongated mounting holes 132, ensure that the roof accessory is securely installed. This helps mitigate safety hazards caused by insecure installation.
