Technical Field

[0001] This invention relates to the field of vehicles, and provides a floor assembly, a chassis, and a vehicle. Background Technology

[0002] As low-carbon and environmentally friendly requirements become increasingly integrated into the product design of the rail transit industry, lightweight design demands are rising. In related technologies, vehicle floors typically have two layers: the car body floor and the passenger compartment floor. This double-layer design makes it difficult to meet lightweight design requirements. Furthermore, installing passenger seats separately on the passenger compartment floor usually requires pre-embedded mounting components, which is not conducive to meeting the fast-paced demands of vehicle assembly. Summary of the Invention

[0004] This invention also provides a base frame.

[0005] This invention also provides a vehicle.

[0006] A first aspect of the present invention provides a floor assembly, comprising:

[0007] The floor body is laid on the underframe of the vehicle body. The floor body includes end floors and middle floors. The end floors correspond to the passenger compartment and the driver's cab, and the middle floor corresponds to the door area.

[0008] Passenger seat mounting bases are integrated and installed on the end floor.

[0009] According to one embodiment of the present invention, the end floor includes:

[0010] A single-end floor is laid on the underframe and corresponds to the driver's cab, wherein the driver's cab shares the underframe of the vehicle body;

[0011] Two-position end floor, laid on the base frame and corresponding to the two-position ends;

[0012] The passenger compartment floor is laid on the base frame and corresponds to the passenger compartment. The passenger compartment floor is located between the first end floor and the middle floor and between the second end floor and the middle floor. The passenger compartment seat mounting base is integrated and installed on the passenger compartment floor.

[0013] According to one embodiment of the present invention, a height difference is formed between the intermediate floor and the guest room floor along the height direction, and the intermediate floor is located below the guest room floor.

[0014] According to one embodiment of the present invention, a vertical panel is provided between the intermediate floor and the guest room floor.

[0015] According to one embodiment of the present invention, a one-position end cap plate for covering the base frame is provided on the one-position end plate, and a two-position end cap plate for covering the base frame is provided on the two-position end plate.

[0016] According to one embodiment of the present invention, a mounting hole and a driver's seat mounting base are provided on the end floor, wherein the mounting hole is used to mount a steering wheel.

[0017] According to one embodiment of the present invention, the first end floor, the second end floor, and the guest room floor are welded and / or riveted together.

[0018] According to one embodiment of the present invention, the guest room floor, the intermediate floor, and the two end floors transition smoothly, and in the direction from the intermediate floor to the two end floors, the guest room floor and the two end floors form an angle with the horizontal plane, and the guest room floor and the two end floors are coplanar.

[0019] A second aspect of the present invention provides a base frame, including base frame side beams and a floor assembly as described above, wherein the floor body is laid on the base frame side beams.

[0020] According to one embodiment of the present invention, the underframe side beam includes a first beam and a second beam. The first end of the first beam is connected to the driver's cab, and the second end of the first beam is connected to a door post. The second beam is connected to the bottom end of the door post. Along the height direction, the connection position between the first beam and the door post is offset from the connection position between the second beam and the door post.

[0021] According to one embodiment of the present invention, an oblique reinforcing beam is provided between the second beam and the first beam;

[0022] Along the length of the base frame side beam, the first beam, the inclined reinforcing beam, and the second beam form a longitudinal force transmission path.

[0023] A third aspect of the present invention provides a vehicle including the floor assembly as described above.

[0024] Or a base frame as described above.

[0025] According to the first aspect of the present invention, the floor assembly is divided into modules such as end floors and intermediate floors, allowing each module to be manufactured and pre-assembled independently before assembly on the vehicle chassis. This modular design not only simplifies the assembly process but also improves assembly efficiency and precision, reducing production costs. The end floors in the floor assembly correspond to the passenger compartment and driver's cab, while the intermediate floors correspond to the door areas. This clear functional zoning makes the interior space layout more rational, facilitating passenger flow and crew operations. Furthermore, the floors in different areas can be designed differently to meet various usage requirements. By laying the floor body on the vehicle chassis and integrating it with components such as passenger seat mounting bases, the overall structural strength of the vehicle is enhanced, improving its stability and safety. The modular design allows each module in the floor assembly to be disassembled and replaced individually, facilitating routine vehicle maintenance. When a module malfunctions or is damaged, only that module needs to be replaced, eliminating the need for a major overhaul of the entire floor assembly, thus reducing maintenance costs and time. By carefully designing each module of the floor assembly, the interior floor layout can be made more aesthetically pleasing and elegant, enhancing the overall quality and image of the vehicle. By integrating the passenger seat mounting brackets into the end floor, pre-integration of the seat mounting structure is achieved, avoiding cumbersome seat installation work inside the vehicle body. This design not only simplifies the installation process but also ensures the stability and consistency of seat installation, improving the passenger experience.

[0026] According to the second aspect of the present invention, the chassis provides a stable load-bearing structure by laying the floor body on the chassis side beams. The chassis side beams, as the main supporting components, can withstand the vehicle's own weight, passenger and cargo weight, and various dynamic loads during operation, ensuring the vehicle's stability and safety. The combination of the chassis side beams and the floor assembly makes the interior space layout more rational. The modular design of the floor assembly allows for flexible adjustments according to actual needs, while the chassis side beams provide a stable supporting foundation; the two work together to optimize the space utilization efficiency inside the vehicle. The pre-assembly and modular design of the chassis side beams and the floor assembly simplify and improve the assembly process of the entire chassis. During vehicle manufacturing, the chassis side beams and the floor assembly can be pre-assembled before being installed onto the vehicle body, reducing on-site assembly workload and improving assembly accuracy and efficiency. Because the floor assembly adopts a modular design, when a module fails or is damaged, it can be disassembled and replaced individually without requiring a major overhaul of the entire chassis. Meanwhile, the underframe side beams, as the main supporting structure, ensure stability and durability, further reducing maintenance costs and complexity. The integration of the underframe side beams and the floor assembly not only prioritizes practicality but also aesthetics. By carefully designing the shape, size, and material parameters of the underframe side beams, as well as details such as the color and texture of the floor assembly, the entire underframe appears more beautiful and sophisticated, enhancing the vehicle's overall grade and image. As the main supporting structure of the underframe, the strength and rigidity of the underframe side beams are fully guaranteed. In the event of a collision or other accident, the underframe side beams effectively absorb and disperse impact energy, protecting the safety of passengers and equipment inside the vehicle. Simultaneously, the tight integration between the floor assembly and the underframe side beams also enhances the overall collision resistance of the underframe.

[0027] The vehicle provided according to the third aspect of the present invention, whether using a floor assembly directly or an integrated chassis, significantly enhances the vehicle's structural strength and stability. The design of the floor assembly and chassis side beams effectively withstands various loads during vehicle operation, ensuring stability and safety under high-speed driving and complex road conditions. The modular design of the floor assembly makes the interior space layout more rational and flexible. Different modules can be combined and adjusted according to actual needs to meet different passenger requirements and vehicle functional requirements. This flexibility not only improves passenger comfort but also enhances the vehicle's practicality and versatility. The integrated design of the floor assembly and seat mounting bases makes seat installation more stable, reducing vibration and noise during driving and improving the passenger experience. Simultaneously, the material selection and surface treatment of the floor assembly emphasize anti-slip, wear-resistant, and easy-to-clean properties, further improving the cleanliness and comfort of the interior. The modular design of the floor assembly and its pre-assembly with the chassis side beams simplify the vehicle assembly process. During vehicle manufacturing, the floor assembly and chassis side beams can be pre-assembled before being installed onto the vehicle body, reducing on-site assembly workload and improving assembly precision and efficiency. Furthermore, the modular design makes maintenance and replacement of the floor assembly more convenient and faster, reducing maintenance costs and time. The design of the floor assembly and chassis not only emphasizes practicality but also aesthetics. Carefully designed appearance and color schemes make the vehicle interior look more beautiful and sophisticated, enhancing the overall grade and image of the vehicle. This aesthetic appeal not only enhances passenger comfort but also improves the vehicle's market competitiveness. The materials and processes used in the floor assembly and chassis undergo rigorous selection and testing to ensure their durability and reliability. These materials and processes resist wear, corrosion, and aging issues encountered during daily use, extending the vehicle's lifespan and reducing repair and replacement costs due to malfunctions.

[0035] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0036] like Figures 1 to 3 As shown, a first aspect of the present invention provides a floor assembly including a floor body 100 and a passenger seat mounting base 106; the floor body 100 is laid on the underframe of the vehicle body, and the floor body 100 includes an end floor 102 and a middle floor 104, the end floor 102 corresponding to the passenger compartment and the driver's compartment, and the middle floor 104 corresponding to the door area; the passenger seat mounting base 106 is integrated and installed on the end floor 102.

[0037] According to the first aspect of the present invention, the floor assembly is divided into modules such as end floor 102 and intermediate floor 104, allowing each module to be manufactured and pre-assembled independently before assembly on the vehicle chassis. This modular design not only simplifies the assembly process but also improves assembly efficiency and precision, reducing production costs. The end floor 102 corresponds to the passenger compartment and driver's cab, while the intermediate floor 104 corresponds to the door area. This clear functional zoning makes the interior space layout more rational, facilitating passenger flow and crew operation. Furthermore, the floor in different areas can be designed differently to meet various usage requirements. By laying the floor body 100 on the vehicle chassis and integrating it with components such as passenger seat mounting bases 106, the overall structural strength of the vehicle is enhanced, improving stability and safety. The modular design allows each module in the floor assembly to be disassembled and replaced individually, facilitating routine vehicle maintenance. When a module malfunctions or is damaged, only that module needs to be replaced, eliminating the need for a major overhaul of the entire floor assembly, thus reducing maintenance costs and time. By carefully designing each module of the floor assembly, the interior floor layout can be made more aesthetically pleasing and elegant, enhancing the overall quality and image of the vehicle. By integrating the passenger seat mounting brackets 106 into the end floor 102, pre-integration of the seat mounting structure is achieved, avoiding cumbersome seat installation work inside the vehicle body. This design not only simplifies the installation process but also ensures the stability and consistency of seat installation, improving the passenger experience.

[0038] Please continue reading Figures 1 to 3 The first aspect of this invention provides an innovative floor assembly design aimed at optimizing the interior space layout of rail vehicles, improving assembly efficiency, and enhancing the passenger experience. The floor assembly mainly consists of two parts: a floor body 100 and passenger seat mounting bases 106.

[0039] The floor body 100 is the foundation of the entire floor assembly. It is laid on the vehicle body's underframe and provides a stable support platform for the vehicle's interior. The floor body 100 is subdivided into two main parts—the end floor 102 and the intermediate floor 104.

[0040] The end floor 102 corresponds to the passenger compartment and driver's cab of the vehicle. Since the passenger compartment and driver's cab are the main activity areas for passengers and crew, the design of the end floor 102 needs to take into account passenger comfort and crew operational convenience.

[0041] The middle floor 104 corresponds to the vehicle's door area. The door area is the main passageway for passengers to get on and off the vehicle, so the design of the middle floor 104 needs to ensure sufficient passage width and anti-slip performance to ensure the safety and smooth passage of passengers.

[0042] To simplify the seat installation process and improve installation stability, this invention integrates the passenger compartment seat mounting base 106 into the end floor 102. This integrated design makes the seat mounting base and the floor body 100 form a whole, avoiding the complex connection and fixing process between the seat and the floor in traditional installation methods.

[0043] The modular design of the floor body 100 (including the end floor 102 and the middle floor 104) and the integrated installation of the passenger seat mounting base 106 simplify and improve the assembly process of the entire floor assembly. During vehicle manufacturing, the floor body 100 and the seat mounting base can be pre-assembled and then installed onto the vehicle body as a whole, thereby reducing on-site assembly workload and improving assembly accuracy and efficiency.

[0044] The integrated design of the passenger seat mounting base 106 makes the seat installation more stable, reduces vibration and noise during driving, and improves passenger comfort. At the same time, the anti-slip and wear-resistant properties of the floor assembly further enhance the cleanliness and safety of the vehicle interior.

[0045] According to one embodiment of the present invention, the end floor 102 includes a first end floor 108, a second end floor 110, and a passenger compartment floor 112; the first end floor 108 is laid on the underframe and corresponds to the driver's cab, wherein the driver's cab shares the underframe of the vehicle body; the second end floor 110 is laid on the underframe and corresponds to the second end floor; the passenger compartment floor 112 is laid on the underframe and corresponds to the passenger compartment, and the passenger compartment floor 112 is located between the first end floor 108 and the intermediate floor 104 and between the second end floor 110 and the intermediate floor 104, and the passenger compartment seat mounting base 106 is integrated and installed on the passenger compartment floor 112.

[0046] See Figures 1 to 3 In one specific embodiment of the present invention, the end floor 102 is further refined into a single end floor 108, a double end floor 110, and a passenger compartment floor 112 to meet the specific needs of different areas of the vehicle.

[0047] One end floor 108 is laid on the underframe of the car body and directly corresponds to the driver's cab. Since the driver's cab is the main working area for the crew, the design of the one end floor 108 needs to consider the crew's operational convenience and comfort. To match the special needs of the driver's cab, the one end floor 108 uses a reinforced structure or special materials to improve its load-bearing capacity and wear resistance. The one end floor 108 is tightly laid on the underframe and shares the car body's underframe with the driver's cab, forming a stable supporting foundation.

[0048] The second-end floor 110 is also laid on the underframe of the vehicle body, but corresponds to the second end of the vehicle (usually the other end of the vehicle, opposite the driver's cab). Considering the passage and standing needs of passengers, the second-end floor 110 needs to ensure sufficient passage width and anti-slip performance.

[0049] The passenger compartment floor 112 is laid on the underframe and directly corresponds to the passenger compartment. It is the main area for passengers to sit and rest, so special attention needs to be paid to passenger comfort and safety during the design. The passenger compartment floor 112 is located between the first end floor 108 and the middle floor 104, and between the second end floor 110 and the middle floor 104, forming the main passenger area inside the vehicle.

[0050] To simplify the seat installation process and improve stability, the passenger compartment seat mounting base 106 is integrated into the passenger compartment floor 112. This design creates a stable whole between the seat and the floor, reducing vibration and noise during driving.

[0051] By subdividing the end floor 102 into a single-position end floor 108, a second-position end floor 110, and a passenger compartment floor 112, a refined design for different areas of the vehicle is achieved. This design not only meets the specific needs of different areas but also improves the adaptability and flexibility of the entire floor assembly. The design of the single-position end floor 108 and the passenger compartment floor 112 places particular emphasis on passenger and crew comfort and ease of operation. By optimizing the floor structure and material selection, vibration and noise during operation are reduced, enhancing the riding experience. The tight integration of each floor section with the underframe and the reinforced structural design enhance the structural stability of the entire floor assembly. This stability is crucial for improving vehicle ride quality and passenger safety.

[0052] According to one embodiment of the present invention, a height difference is formed between the intermediate floor 104 and the guest room floor 112 along the height direction, and the intermediate floor 104 is located below the guest room floor 112.

[0053] In one specific embodiment of the present invention, a significant height difference is designed between the intermediate floor 104 and the passenger compartment floor 112 along the vertical direction, and the intermediate floor 104 is located below the passenger compartment floor 112. This design aims to optimize the spatial layout inside the vehicle and improve passenger passage efficiency and riding experience.

[0054] By creating a height difference, the central floor area 104 (typically the door area) can be visually and functionally distinguished from the passenger compartment floor area 112. This distinction helps guide passenger flow, improves traffic efficiency, and enhances the sense of spatial hierarchy within the vehicle.

[0055] The lower center floor 104 serves as the main passageway for passengers getting on and off the vehicle. This design helps reduce the step height required for passengers, improving passage efficiency, and is particularly user-friendly for passengers with mobility impairments. The height difference also provides more possibilities for utilizing interior space. For example, storage spaces, equipment compartments, or other functional areas can be located beneath the center floor 104 to fully utilize the vehicle's vertical space. The height difference design enhances the sense of space and hierarchy within the vehicle, making the overall layout more aesthetically pleasing and harmonious. Furthermore, through appropriate color schemes and material selection, the visual experience for passengers can be further improved.

[0056] The height difference design makes the interior space layout of the vehicle more rational and efficient. It helps to distinguish different functional areas, improves traffic flow, and makes full use of the vehicle's vertical space. By reducing the step height for passengers getting on and off and providing auxiliary facilities, the height difference design improves passenger efficiency and comfort. At the same time, the aesthetically pleasing visual effect also enhances the passenger experience. The height difference design provides more possibilities for space utilization inside the vehicle. For example, storage spaces, equipment compartments, and other functional areas can be set up to meet different usage needs. Through reasonable transition designs and the provision of auxiliary facilities such as handrails, the height difference design ensures passenger safety during passage. Especially in emergencies, these designs can help passengers evacuate quickly and safely.

[0057] According to one embodiment of the present invention, a vertical panel 114 is provided between the intermediate floor 104 and the guest room floor 112.

[0058] See Figure 1 and Figure 2 In one specific embodiment of the present invention, in order to further distinguish and separate the functional areas of the intermediate floor 104 and the passenger compartment floor 112, and at the same time improve the overall aesthetics and safety of the vehicle interior, a vertical plate 114 is provided between the intermediate floor 104 and the passenger compartment floor 112.

[0059] The upright panel 114 acts as a physical barrier, clearly defining the areas of the intermediate floor 104 (door area) and the passenger compartment floor 112. This division helps passengers visually identify different functional areas and guides their behavior. The upright panel 114 can, to some extent, prevent passengers from accidentally falling into the door area or other unsafe areas during vehicle operation. It provides additional safety, especially during emergency braking or cornering. The design of the upright panel 114 can be integrated into the overall style of the vehicle interior, enhancing its aesthetics through different material, color, and texture choices. The upright panel 114 can be installed between the intermediate floor 104 and the passenger compartment floor 112 via welding, bolting, or other reliable fixing methods. It is essential to ensure that the upright panel 114 is stable and reliable, and will not loosen or collapse due to vibrations during vehicle operation. The height and width of the upright panel 114 should be designed according to the specific dimensions and functional requirements of the vehicle. Generally, the height of the upright panel 114 should be high enough to provide an effective barrier function, but not so high as to obstruct passenger visibility and passage. The width should be reasonably set according to the width of the door area and passenger flow.

[0060] According to one embodiment of the present invention, a first-position end plate 116 for covering the base frame is provided on a first-position end plate 108, and a second-position end plate 118 for covering the base frame is provided on a second-position end plate 110.

[0061] In one specific embodiment of the present invention, in order to enhance the cleanliness and aesthetics of the vehicle interior, and at the same time protect the underframe from adverse factors such as dust, moisture and corrosion, a first-position end plate 116 for covering the underframe is provided on the first-position end floor 108, while a second-position end plate 118 for covering the underframe is provided on the second-position end floor 110.

[0062] An end cap 116 is installed on the end floor 108, and its main function is to cover and protect the exposed portion of the vehicle underframe in the driver's cab area. This not only prevents dust, moisture, and corrosive substances from entering the underframe, but also improves the overall aesthetics of the vehicle interior.

[0063] One end cap 116 can be made of a material that matches the floor body 100, such as metal, plastic, or composite materials. Its structural design should ensure stability and reliability, fit tightly against the base frame surface, and have a certain degree of impact resistance and corrosion resistance.

[0064] Similar to the first-position end cover 116, the second-position end cover 118 is mounted on the second-position end floor 110 to cover and protect the exposed portions of the vehicle underframe in the second-position area. This also helps prevent the intrusion of dust, moisture, and corrosive substances, and enhances the aesthetics of the vehicle interior.

[0065] The material and structural requirements for the second-position end cap 118 are similar to those for the first-position end cap 116, requiring good stability, impact resistance, and corrosion resistance. Furthermore, its design should also consider coordination with other vehicle components and overall aesthetics.

[0066] The first end cap 116 and the second end cap 118 can be installed on the floor using bolts, welding, or other reliable fixing methods. During installation, ensure a tight fit between the end caps and the floor and base frame to prevent loosening or detachment. To improve the sealing performance of the end caps, sealant can be applied to the contact surfaces between the end caps and the floor and base frame, or other sealing measures can be used. This helps prevent the penetration of dust, moisture, and corrosive substances, protecting the base frame from damage.

[0067] The installation of the first end cap 116 and the second end cap 118 effectively covers the exposed parts of the underframe, reducing the accumulation of dust and debris and improving the cleanliness and aesthetics of the vehicle interior. The first end cap 116 and the second end cap 118 can prevent moisture, corrosive substances and other adverse factors from eroding the underframe, extending the service life of the underframe and reducing maintenance costs.

[0068] According to one embodiment of the present invention, a mounting hole 120 and a driver's seat mounting base 122 are provided on a driver's end floor 108, wherein the mounting hole 120 is used to mount a steering wheel.

[0069] In one specific embodiment of the present invention, in order to meet the installation requirements of the equipment inside the driver's cab, the end floor 108 is specially designed with mounting holes 120 and driver's cab seat mounting bases 122. These design details not only ensure the stable installation of the equipment in the driver's cab, but also improve the overall functionality and comfort of the driver's cab.

[0070] Mounting holes 120 are formed in the first-end floor 108, and their primary function is to mount the steering wheel. The size, shape, and position of these holes are precisely calculated and designed to ensure that the steering wheel can be securely and accurately mounted in the predetermined position. Mounting holes 120 may be threaded to mate with bolts or nuts on the steering wheel mounting bracket for a tight connection. In addition, to enhance the durability and wear resistance of mounting holes 120, they may be treated with reinforcing materials or special coatings.

[0071] The driver's cab seat mounting bracket 122 is integrated into the end floor 108 to secure the driver's seat. This mounting bracket is designed with the driver's comfort and ease of operation in mind, ensuring the seat provides stable support for the driver's body and offering necessary adjustments. The driver's cab seat mounting bracket 122 may be made of a metal frame or composite materials, possessing sufficient strength and rigidity to withstand the driver's weight and operating forces. Additionally, the mounting bracket may include adjustment mechanisms, such as slide rails or lifting rods, allowing the driver to adjust the seat's position and angle according to their individual needs.

[0072] The design of the mounting holes 120 and the driver's cab seat mounting bracket 122 allows the equipment inside the driver's cab to be securely and accurately installed in predetermined positions, thereby improving the overall functionality of the driver's cab. The driver's cab seat mounting bracket 122 is designed with the driver's comfort in mind, providing stable support and necessary adjustments to ensure the driver maintains a comfortable posture during long driving sessions. The stable seat mounting bracket and steering wheel mounting holes 120 help reduce safety hazards caused by loose or detached equipment, improving driver safety during driving.

[0073] According to one embodiment of the present invention, the first end floor 108, the second end floor 110, and the passenger compartment floor 112 are welded and / or riveted together.

[0074] In one specific embodiment of the present invention, to ensure the stability and integrity of the vehicle's interior floor structure, the first-position end floor 108, the second-position end floor 110, and the passenger compartment floor 112 are connected by welding and / or riveting. This connection method not only effectively resists vibrations and impacts generated during vehicle operation but also improves the load-bearing capacity and durability of the floor structure.

[0075] Welded connections can be achieved through manual welding, automatic welding, or semi-automatic welding. When choosing a welding method, the properties of the flooring material, the structure of the connection area, and the requirements of the welding process must be considered.

[0076] Riveting connections typically use specialized riveting equipment, such as rivet guns or riveting machines. During the connection process, rivets are inserted into pre-drilled holes and deformed by the pressure of the riveting equipment, thus achieving a strong connection between the floorboards.

[0077] In embodiments of the present invention, the first end floor 108, the second end floor 110, and the guest room floor 112 may be connected using both welding and riveting methods. This combined connection method can fully utilize the advantages of both connection methods, further improving the stability and overall performance of the floor structure.

[0078] For example, welding can be used in the main load-bearing parts of the floor or in areas requiring high-strength connections; while riveting can be used in some auxiliary connection parts or in areas requiring quick installation and disassembly.

[0079] Welding and / or riveting ensures a robust, integrated structure between floor panels, effectively resisting vibrations and impacts generated during vehicle operation and enhancing the stability of the floor structure. Through welding and / or riveting, the floor structure can withstand greater loads, meeting the usage requirements of vehicles under various operating conditions.

[0080] According to one embodiment of the present invention, the guest room floor 112 smoothly transitions with the intermediate floor 104 and the second end floor 110. From the intermediate floor 104 to the second end floor 110, the guest room floor 112 and the second end floor 110 form an angle with the horizontal plane, and the guest room floor 112 and the second end floor 110 are coplanar.

[0081] In a specific embodiment of the present invention, in order to improve passenger comfort and space utilization, the connection between the passenger compartment floor 112, the middle floor 104 and the second end floor 110 adopts a unique smooth transition design. From the middle floor 104 to the second end floor 110, the passenger compartment floor 112 and the second end floor 110 form an angle that gradually increases with the horizontal plane, and finally the passenger compartment floor 112 and the second end floor 110 reach a coplanar state at the end.

[0082] A smooth transition refers to a floor surface without noticeable steps or height differences, allowing passengers to experience a continuous and unobstructed change in ground level while walking. In this embodiment, the connections between the passenger compartment floor 112 and the intermediate floor 104, as well as between the intermediate floor 104 and the two end floors 110, have been carefully designed to ensure a smooth transition. This design not only enhances passenger comfort but also reduces the risk of tripping due to steps or height differences, thereby improving the safety of the vehicle interior.

[0083] From the middle floor 104 towards the two end floors 110, the passenger compartment floor 112 and the two end floors 110 form an angle with the horizontal plane. This sloping design helps guide the passenger's line of sight and walking direction, while also increasing the sense of space inside the vehicle to some extent. The coplanar design of the passenger compartment floor 112 and the two end floors 110 makes the use of space inside the vehicle more efficient, while also providing passengers with a more spacious standing and walking area.

[0084] The smooth transitions and sloping design allow passengers to experience a more continuous and unobstructed change in ground level when walking inside the vehicle, thus improving ride comfort. It reduces the risk of tripping over steps or height differences, enhancing vehicle interior safety. The sloping design also increases the sense of space inside the vehicle, making passengers feel more spacious and comfortable.

[0085] See Figure 4 A second aspect of the present invention provides a base frame, including a base frame side beam 124 and a floor assembly as described above, wherein the floor body 100 is laid on the base frame side beam 124.

[0086] See Figure 4 According to the second aspect of the present invention, the chassis frame, by laying the floor body 100 on the chassis side beam 124, forms a stable load-bearing structure. The chassis side beam 124, as the main supporting component, can withstand the vehicle's own weight, passenger and cargo weight, and various dynamic loads during operation, ensuring the vehicle's stability and safety. The combination of the chassis side beam 124 and the floor assembly makes the interior space layout more rational. The modular design of the floor assembly allows for flexible adjustments according to actual needs, while the chassis side beam 124 provides a stable supporting foundation; the two work together to optimize the space utilization efficiency inside the vehicle. The pre-assembly and modular design of the chassis side beam 124 and the floor assembly simplify and improve the assembly process of the entire chassis. During vehicle manufacturing, the chassis side beam 124 and the floor assembly can be pre-assembled before being installed onto the vehicle body, thereby reducing on-site assembly workload and improving assembly accuracy and efficiency. Because the floor assembly adopts a modular design, when a module malfunctions or is damaged, it can be disassembled and replaced individually without requiring a major overhaul of the entire chassis. Meanwhile, the chassis side beam 124, as the main support structure, ensures stability and durability, further reducing maintenance costs and complexity. The integration of the chassis side beam 124 and the floor assembly prioritizes both practicality and aesthetics. Careful design of the shape, size, and material parameters of the chassis side beam 124, along with details such as the color and texture of the floor assembly, makes the entire chassis look more beautiful and sophisticated, enhancing the vehicle's overall grade and image. As the main support structure of the chassis, the strength and rigidity of the chassis side beam 124 are fully guaranteed. In the event of a collision or other accidents, the chassis side beam 124 effectively absorbs and disperses impact energy, protecting the safety of passengers and equipment inside the vehicle. Simultaneously, the tight integration between the floor assembly and the chassis side beam 124 enhances the overall crashworthiness of the chassis.

[0087] See Figure 4According to one embodiment of the present invention, the underframe side beam 124 includes a first beam 126 and a second beam 128. The first end of the first beam 126 is connected to the driver's cab, the second end of the first beam 126 is connected to a door post 130, and the second beam 128 is connected to the bottom end of the door post 130. Along the height direction, the connection position between the first beam 126 and the door post 130 is offset from the connection position between the second beam 128 and the door post 130.

[0088] In one embodiment of the invention, the design of the underframe side beam 124 is further optimized. Specifically, the underframe side beam 124 is composed of a first beam 126 and a second beam 128, and is connected to the door pillar 130 in the side wall assembly in a specific manner. This design not only enhances the structural strength of the vehicle body but also improves the overall stability and safety.

[0089] In this embodiment of the invention, the underframe side beam 124 is no longer a single structure, but is composed of two parts: a first beam 126 and a second beam 128. This segmented design allows the underframe side beam 124 to distribute forces more rationally when bearing loads, thereby enhancing its load-bearing capacity and resistance to deformation.

[0090] The first beam 126 is connected at both ends to the portal column 130 and the driver's cab, respectively. This connection ensures a stable connection between the underframe side beam 124 and the driver's cab, while also providing reliable support for the side walls. The second beam 128 is directly connected to the bottom of the portal column 130, further enhancing the stability of the portal column 130. It is worth noting that, along the height direction, the connection points of the first beam 126 and the portal column 130 are staggered with those of the second beam 128. This staggered design more effectively disperses and resists forces from different directions, improving the overall stability of the vehicle body.

[0091] The segmented design of the underframe side beam 124 and its staggered connection with the portal column 130 significantly enhance the structural strength of the vehicle body. This design better resists impacts and vibrations during driving, ensuring the stability and safety of the vehicle body. The staggered connection makes the connection between the underframe side beam 124 and the portal column 130 more robust and reliable, reducing safety hazards caused by loosening or breakage at the connection point. At the same time, this design also helps improve the overall stability of the vehicle body, enabling it to maintain a stable driving state under various road conditions.

[0092] In summary, this embodiment of the present invention further enhances the structural strength, stability, and safety of the vehicle body by optimizing the design of the underframe side beam 124. At the same time, this design also maintains good space utilization and ease of maintenance.

[0093] According to one embodiment of the present invention, an oblique reinforcing beam 132 is provided between the second beam 128 and the first beam 126; along the length direction of the bottom frame side beam 124, the first beam 126, the oblique reinforcing beam 132 and the second beam 128 form a longitudinal force transmission path.

[0094] In this embodiment of the invention, the first beam 126, the diagonal reinforcing beam 132, and the second beam 128 are cleverly combined along the length of the underframe side beam 124 to form an efficient longitudinal force transmission path. This design not only optimizes the mechanical properties of the vehicle body but also ensures the smooth transmission of force in the vehicle body structure, thereby improving the stability and durability of the overall structure.

[0095] This path is a main force transmission channel constructed along the length of the underframe side beam 124. It begins at the first beam 126, is supported and guided by the diagonal reinforcing beam 132, and then transmits the force to the second beam 128. This path tightly connects the various key components of the vehicle body, forming a cohesive whole. When the vehicle is subjected to longitudinal forces (such as traction, braking, or impact), these forces first act on the first beam 126. Because the first beam 126 is connected to the door pillars 130 and the driver's cab, it can effectively distribute the force throughout the entire vehicle body structure. Subsequently, the diagonal reinforcing beam 132, as an important supporting structure, guides the force to the second beam 128. The second beam 128 can further transmit the force to the side walls and the entire vehicle body through structures such as the measuring pillars. Ultimately, this force transmission path distributes the longitudinal forces to a wider area, thereby ensuring the overall stability of the vehicle body.

[0096] The construction of the longitudinal force transmission path significantly optimizes the mechanical performance of the vehicle body. It ensures smooth force transmission and rational distribution within the vehicle structure, reducing localized stress concentration and thus improving the overall strength and durability of the vehicle body. Through the force transmission mechanism of the longitudinal path, the vehicle body maintains a stable posture when subjected to longitudinal forces. Even at high speeds or in the event of emergencies, the vehicle body can respond quickly and adjust its posture to ensure the safety of passengers and cargo. The longitudinal force transmission path tightly connects the various key components of the vehicle body, forming a collaborative whole. This design allows the vehicle body to quickly mobilize the forces of various components to resist and balance external forces, thereby improving its overall anti-rollover and anti-overturning capabilities. Although the longitudinal force transmission path involves multiple components and complex connections, the overall structure remains simple and clear through rational layout and design. This design not only reduces manufacturing costs and complexity but also facilitates subsequent maintenance and repair work.

[0097] See Figure 4 A third aspect of the present invention provides a vehicle including the floor assembly as described above, or the chassis as described above.

[0098] The vehicle provided according to the third aspect of the present invention, whether using a floor assembly directly or an integrated chassis, significantly enhances the vehicle's structural strength and stability. The design of the floor assembly and chassis side beams 124 effectively withstands various loads during vehicle operation, ensuring the vehicle's stability and safety under high-speed driving and complex road conditions. The modular design of the floor assembly makes the interior space layout more rational and flexible. Different modules can be combined and adjusted according to actual needs to meet different passenger needs and vehicle functional requirements. This flexibility not only improves passenger comfort but also enhances the vehicle's practicality and versatility. The integrated design of the floor assembly and seat mounting bases makes seat installation more stable, reducing vibration and noise during driving and improving the passenger experience. Simultaneously, the material selection and surface treatment of the floor assembly emphasize anti-slip, wear-resistant, and easy-to-clean properties, further improving the cleanliness and comfort of the interior. The modular design of the floor assembly and its pre-assembly with the chassis side beams 124 simplify the vehicle assembly process. During vehicle manufacturing, the floor assembly and chassis side beams 124 can be pre-assembled before being installed onto the vehicle body, reducing on-site assembly workload and improving assembly precision and efficiency. Furthermore, the modular design makes maintenance and replacement of the floor assembly more convenient and faster, reducing maintenance costs and time. The design of the floor assembly and chassis not only emphasizes practicality but also aesthetics. Through carefully designed appearance and color schemes, the vehicle interior looks more beautiful and sophisticated, enhancing the overall grade and image of the vehicle. This aesthetic appeal not only enhances passenger comfort but also improves the vehicle's market competitiveness. The materials and processes used in the floor assembly and chassis undergo rigorous selection and testing to ensure their durability and reliability. These materials and processes resist wear, corrosion, and aging issues encountered during daily use, extending the vehicle's service life and reducing repair and replacement costs due to malfunctions.
