Description

Technical Field

[0001] This invention relates to the field of automotive manufacturing technology, and more specifically, to an integrated side floor and a vehicle having therein. Background Technology

[0002] Driven by increasingly stringent emission and energy consumption standards and range requirements, lightweighting of commercial vehicles has become a necessity. However, the multi-configuration and small-batch production characteristics of cabs limit the large-scale application of their integral cast aluminum floor structures. To overcome this bottleneck, a feasible approach is to shift towards integrated die casting of key substructures such as the cab side floor, achieving effective weight reduction while also considering production flexibility, assembly efficiency, and ease of maintenance.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide an integrated side floor and a vehicle having it, in order to solve the problem of low production and assembly efficiency of integrated cast side floors in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an integrated side floor is provided, comprising: a side floor body, the side floor body including at least an upper plate, a front plate, a first side plate, and a second side plate, the upper plate being connected to at least one of the front plate, the first side plate, and the second side plate, at least a portion of the first side plate extending along the height direction of the side floor, at least a portion of the second side plate extending along the height direction of the side floor, the first side plate and the second side plate being disposed at a distance along the width direction of the side floor to form an installation space between the first side plate and the second side plate, the front plate being used for connection with a front suspension; an opening communicating with the installation space is provided on the side of the upper plate near the front suspension, a third side plate is disposed on the edge of the upper plate away from the front plate, the third side plate and the first side plate, the front plate, and the second side plate being sequentially connected along the circumference of the opening to form a suspension reinforcement space, a reinforcing rib assembly being disposed within the suspension reinforcement space; wherein, the side floor body is integrally cast.

[0006] Furthermore, the side floor body also includes a partition plate, which is connected to the third side plate, the first side plate, the front plate, and the second side plate. The partition plate is disposed within the suspended reinforcement space. The side of the partition plate facing the upper plate, together with the third side plate, part of the first side plate, part of the front plate, and part of the second side plate, forms a reinforcement chamber. The side of the partition plate away from the upper plate, together with part of the first side plate, part of the front plate, and part of the second side plate, forms part of the sidewall of the suspended reinforcement space. The reinforcement chamber communicates with the outside through an opening.

[0007] Furthermore, at least a portion of the first side panel and at least a portion of the second side panel extend along the length of the side floor. Both the first and second side panels have a suspended fixing plate segment and an extension segment. One side of the suspended fixing plate segment is connected to the front panel, and the other side of the suspended fixing plate segment is connected to the extension segment. The suspended fixing plate segments of the first and second side panels are arranged opposite to each other, and the two suspended fixing plate segments, together with the front panel and the third side panel, form a suspended reinforcement space.

[0008] Furthermore, along the length of the edge floor, the suspended fixing plate segment extends from the side closest to the front plate to the side closest to the extension segment. The distance between the end of the suspended fixing plate segment furthest from the upper plate and the upper plate is first increased and then decreased. The maximum distance between the end of the suspended fixing plate segment furthest from the upper plate and the upper plate is H, where 235mm≤H≤265mm.

[0009] Furthermore, the reinforcing rib assembly includes a first reinforcing rib, which protrudes from the outer surface of the partition plate body facing the opening. At least a portion of the first reinforcing rib extends along the height direction of the side floor. There are multiple first reinforcing ribs, which are sequentially connected along the length direction of the side floor, and are arranged at an angle between adjacent first reinforcing ribs.

[0010] Furthermore, along the thickness direction of the first reinforcing rib, the first reinforcing rib has two opposite reinforcing surfaces, and along the height direction of the side floor, the distance between the two reinforcing surfaces gradually decreases from bottom to top.

[0011] Furthermore, the reinforcing rib assembly also includes a second reinforcing rib, which protrudes from the outer surface of the partition plate on the side away from the opening. There are multiple second reinforcing ribs connected together, and adjacent second reinforcing ribs are arranged at an angle.

[0012] Furthermore, at least one connecting hole is provided on the suspension fixing plate segment, and at least one reinforcing rib is provided on the side of the suspension fixing plate segment away from the suspension reinforcement space. One end of the reinforcing rib protrudes circumferentially from the connecting hole and is provided at the connecting hole, and the other end of the reinforcing rib is connected to the upper plate body.

[0013] Furthermore, the edge floor itself is made of aluminum alloy.

[0014] According to another aspect of the present invention, a vehicle is provided having an integrated side floor, wherein the integrated side floor is the integrated side floor described above.

[0015] By applying the technical solution of this invention, the upper plate, front plate, first side plate, and second side plate are integrated into a single unit. This integrated molding process achieves a high degree of integration of the side floor, reducing the number of parts, simplifying the assembly process, and improving the overall structural rigidity and strength. The first and second side plates extend along the height of the side floor, and the installation space formed between them provides necessary layout space for the vehicle interior, while also enhancing the side floor's support for the front and lateral suspension. The opening on the upper plate near the front suspension, and the third side plate added to the edge of the opening, together with the first, front, and second side plates, form a suspension reinforcement space. This effectively improves the strength and stability of the connection to the front suspension, preventing fatigue damage caused by vibration or impact during vehicle operation, thereby extending the service life of the side floor. Furthermore, the reinforcing ribs within the suspension reinforcement space further enhance the overall rigidity of the side floor, making the entire side floor structure more stable and contributing to improved vehicle handling and safety.

[0027] Combination Figures 1 to 3 As shown, according to a specific embodiment of this application, an integrated edge floor is provided.

[0028] Specifically, such as Figure 1As shown, the integrated side panel includes a side panel body 10. The side panel body 10 includes at least an upper panel 11, a front panel 12, a first side panel 13, and a second side panel 14. The upper panel 11 is connected to at least one of the front panel 12, the first side panel 13, and the second side panel 14. At least a portion of the first side panel 13 extends along the height direction of the side panel, and at least a portion of the second side panel 14 extends along the height direction of the side panel. The first side panel 13 and the second side panel 14 are spaced apart along the width direction of the side panel, so that the first side panel 13 and the second side panel 14 are spaced apart. An installation space 100 is formed between the two sides, and the front plate 12 is used to connect with the front suspension. The upper plate 11 has an opening 110 on the side near the front suspension that communicates with the installation space 100. A third side plate 15 is provided on the edge of the opening 110 of the upper plate 11 away from the front plate 12. The third side plate 15, the first side plate 13, the front plate 12, and the second side plate 14 are connected in sequence along the circumference of the opening 110 to form a suspension reinforcement space 101. A reinforcing rib assembly 20 is provided in the suspension reinforcement space 101. The side plate body 10 is integrally cast.

[0029] The technical solution of this embodiment adopts an integrated configuration of the upper plate 11, front plate 12, first side plate 13, and second side plate 14. This integrated molding process achieves a high degree of integration of the side floor, reducing the number of parts, simplifying the assembly process, and improving the overall structural rigidity and strength. The first side plate 13 and second side plate 14 extend along the height direction of the side floor, and the installation space 100 formed between them provides necessary layout space for the vehicle interior, while also enhancing the side floor body 10's support capacity for the front suspension and lateral movement. The opening 110 on the upper plate 11 near the front suspension, and the third side plate 15 added to the edge of the opening 110, together with the first side plate 13, front plate 12, and second side plate 14, form a suspension reinforcement space 101. This effectively improves the strength and stability of the connection with the front suspension, avoiding fatigue damage caused by vibration or impact during vehicle operation, thereby extending the service life of the side floor. In addition, the reinforcing rib assembly 20 installed inside the suspension reinforcement space 101 further enhances the overall rigidity of the side floor, making the entire side floor structure more stable and helping to improve the vehicle's handling performance and safety.

[0030] Specifically, such as Figure 2As shown, the side floor body 10 also includes a partition plate 16, which is connected to the third side plate 15, the first side plate 13, the front plate 12, and the second side plate 14. The partition plate 16 is disposed in the suspended reinforcement space 101. The side of the partition plate 16 facing the upper plate 11, together with the third side plate 15, part of the first side plate 13, part of the front plate 12, and part of the second side plate 14, forms a reinforcement chamber 102. The side of the partition plate 16 away from the upper plate 11, together with part of the first side plate 13, part of the front plate 12, and part of the second side plate 14, forms part of the sidewall of the suspended reinforcement space 101. The reinforcement chamber 102 communicates with the outside through an opening 110.

[0031] The side floor body 10 incorporates a partition plate 16. Through its connection with the third side plate 15, the first side plate 13, the front plate 12, and the second side plate 14, the partition plate 16 forms a reinforced chamber 102 within the suspended reinforced space 101. This partition plate 16 divides the suspended reinforced space 101 into upper and lower parts, with the upper part forming the reinforced chamber 102. During the integrated casting of the side floor, the molten metal can be ejected from both sides of the partition plate 16 as it flows through the first side plate 13 and the second side plate 14. This allows for ejection from both the moving and stationary sides of the front suspended mounting point, reducing the maximum wall thickness of the first and second side plates 13 and the maximum ejection depth, while improving mold strength and reducing ejection difficulty. Furthermore, the partition plate 16 enhances the overall structural rigidity and compressive strength, thereby increasing the stability of the suspended reinforced space 101. Furthermore, the formation of the reinforced chamber 102 improves the vibration characteristics of the side floor, reduces noise generation, and enhances vehicle comfort and driving experience. The partition plate 16, especially the side furthest from the upper plate 11, forms the sidewall of the suspension reinforcement space 101 with the first side plate 13, the front plate 12, and the second side plate 14. This effectively enhances the load-bearing capacity near the front suspension connection point, ensuring a secure connection between the front suspension connection point and the side floor body 10, and improving driving safety.

[0032] Specifically, at least a portion of the first side panel 13 and at least a portion of the second side panel 14 extend along the length of the side floor. Both the first side panel 13 and the second side panel 14 have a suspended fixing segment 131 and an extension segment 132. One side of the suspended fixing segment 131 is connected to the front panel 12, and the other side is connected to the extension segment 132. The suspended fixing segments 131 of the first side panel 13 and the second side panel 14 are arranged opposite to each other. The two suspended fixing segments 131, together with the front panel 12 and the third side panel 15, form a suspended reinforcement space 101. The suspended reinforcement space 101 allows the side floor to optimize its structural layout while ensuring strength and rigidity, providing ample installation space and a stable support foundation for subsequent layout, thereby balancing the lightweight and functionality of the side floor. The connection between the suspension fixing plate segment 131 and the extension segment 132 not only enhances the overall stability of the side floor but also facilitates precise matching and assembly with other cab components, improving manufacturing and maintenance efficiency. Furthermore, it provides space for the arrangement of the reinforcing rib assembly 20, further enhancing the load-bearing capacity and durability of the side floor.

[0033] Furthermore, along the length of the side floor, the suspended fixing plate segment 131 extends from the side near the front plate 12 to the side near the extension segment 132. The distance between the end of the suspended fixing plate segment 131 away from the upper plate 11 and the upper plate 11 first increases and then decreases. The maximum distance between the end of the suspended fixing plate segment 131 away from the upper plate 11 and the upper plate 11 is H, where 235mm≤H≤265mm.

[0034] In this embodiment, the suspension fixing plate segment 131 is positioned along the length of the side floor, extending from the side closest to the front plate 12 to the side closest to the extension segment 132. This effectively optimizes the rigidity and stability of the side floor in the suspension area. Simultaneously, by adjusting the H value within a reasonable range, sufficient structural strength can be ensured to withstand the load from the suspension while reducing the overall weight of the side floor. The arrangement of increasing the distance between the end of the suspension fixing plate segment 131 furthest from the upper plate 11 and the upper plate 11, followed by decreasing it, also promotes uniform stress distribution during the die-casting process of the integrated side floor, reduces die-casting defects, and improves the success rate of one-time molding. Furthermore, the appropriate selection of the H value simplifies subsequent assembly processes, enhances the matching degree between the front suspension and the side floor, and improves the overall performance and reliability of the vehicle.

[0035] It should be noted that the maximum distance H between the end of the suspension fixing plate segment 131 furthest from the upper plate 11 and the upper plate 11 is preferably 250mm, which ensures sufficient structural strength to withstand the load brought by the suspension. Simultaneously, to ensure the distance H between the suspension fixing plate segment 131 of the first side plate 13 and the second side plate 14, the draft angle of the suspension fixing plate segment 131 needs to be increased synchronously, resulting in excessive wall thickness of the suspension fixing plate segment 131, which is prone to internal defects. Therefore, by setting a partition plate 16 in the middle of the suspension fixing plate segment 131, the wall thickness of the suspension fixing plate segment 131 can be reduced, the maximum draft depth can be reduced, and bidirectional drafting can be achieved. This improves casting efficiency and reduces process difficulty.

[0036] Furthermore, such as Figure 3 As shown, the reinforcing rib assembly 20 includes a first reinforcing rib 21, which protrudes from the outer surface of the partition plate 16 facing the opening 110. At least a portion of the first reinforcing rib 21 extends along the height direction of the side floor. Multiple first reinforcing ribs 21 are sequentially connected along the length direction of the side floor, and adjacent first reinforcing ribs 21 are angled together. The reinforcing rib assembly 20 not only enhances the structural rigidity of the side floor but also optimizes the force transmission path through angle changes, improving the overall performance of the side floor. By providing the first reinforcing rib 21 on the side of the partition plate 16 facing the opening 110, the structural stability of the suspension reinforcement space can be effectively strengthened, further improving the vehicle's durability and safety under complex road conditions. Furthermore, the multi-angle connection design of the first reinforcing rib 21 can better adapt to forces in different directions, ensuring that the side floor maintains good structural stability and mechanical properties under various load conditions, thereby providing more reliable support for the cab.

[0037] Specifically, along the thickness direction of the first reinforcing rib 21, the first reinforcing rib 21 has two oppositely arranged reinforcing surfaces, and the distance between the two reinforcing surfaces gradually decreases from bottom to top along the height direction of the side floor. As the distance between the two reinforcing surfaces decreases, the first reinforcing rib 21 forms a more compact structure in the upper region, which not only reduces the weight of the integrated side floor but also improves its bending resistance without affecting its strength, thereby achieving a balance between lightweighting and structural strength. In addition, the gradually changing arrangement of the reinforcing ribs also helps to optimize material distribution, reduce material waste, lower production costs, and ensure the driving safety and comfort of the vehicle under complex road conditions.

[0038] Furthermore, the reinforcing rib assembly 20 also includes a second reinforcing rib 22, which protrudes from the outer surface of the partition plate 16 on the side away from the opening 110. There are multiple second reinforcing ribs 22, which are connected together, and are arranged at an angle between adjacent second reinforcing ribs 22.

[0039] In this embodiment, the second reinforcing rib 22 works in conjunction with the first reinforcing rib to enhance the structural strength and stability of the partition plate 16. Multiple second reinforcing ribs 22 are connected and arranged at an angle between adjacent ribs, forming a staggered reinforcing structure. This helps to disperse stress, reduce stress concentration, and further improve the torsional resistance and rigidity of the side floor body 10, reducing the possibility of deformation under external impact or load, thereby extending the service life of the integrated side floor. Furthermore, the arrangement of multiple second reinforcing ribs 22 increases the contact area with the upper plate, helping to improve heat conduction performance and control the vehicle's interior temperature.

[0040] Furthermore, at least one connecting hole 133 is provided on the suspension fixing plate segment 131, and at least one reinforcing rib 134 is provided on the side of the suspension fixing plate segment 131 away from the suspension reinforcing space 101. One end of the reinforcing rib 134 protrudes circumferentially from the connecting hole 133 and is provided at the connecting hole 133, and the other end of the reinforcing rib 134 is connected to the upper plate body 11.

[0041] In this embodiment, the connecting hole 133 ensures a secure connection between the side floor and the front suspension or frame, while the reinforcing rib 134 effectively disperses stress concentration around the connecting hole 133, enhancing the overall stability of the structure and improving the tensile strength and shear resistance of the local area of ​​the suspension fixing plate segment 131, thus ensuring the reliability and safety of the side floor under dynamic loads. Furthermore, the connection between the reinforcing rib 134 and the upper plate 11 increases the structural integrity of the entire side floor, helping to improve vibration and noise issues during vehicle operation and enhancing the driving experience.

[0042] It should be noted that the number, shape, and position of the reinforcing ribs 134 can be adjusted according to the specific vehicle model and usage conditions.

[0043] In one embodiment of this application, the side floor body 10 is made of aluminum alloy. Using aluminum alloy as the material for the side floor body 10 allows for better integration of the reinforcing rib assembly 20 during the integral molding process, achieving a balance between lightweight and high strength, thereby improving vehicle driving stability and safety. Furthermore, the high thermal conductivity of aluminum alloy helps the side floor maintain good thermal management under complex operating conditions, reducing the impact of thermal stress on the structure and extending the service life of the side floor.

[0044] According to another aspect of the present invention, a vehicle is also provided, the vehicle having an integrated side floor, the integrated side floor being the integrated side floor of the above embodiments. The side floor body 10 is manufactured using an integrated casting process, achieving lightweight and high strength of the vehicle. Furthermore, by providing the suspension reinforcement space 101 area and the reinforcing rib assembly 20, the rigidity of the side floor is further enhanced, providing strong protection for the stability and reliability of the vehicle under dynamic loads, thereby improving the overall performance of the vehicle.

[0045] In one exemplary embodiment proposed in this application, the side floor can be flexibly adjusted according to different cab configurations to meet the production needs of multiple configurations and small batches.

[0046] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0047] 1) Improved structural strength and rigidity: The integrated cast side floor body 10, combined with the suspension reinforcement space 101, the reinforcement chamber 102 and the reinforcing rib assembly 20, enhances the overall structural strength and rigidity of the side floor, enabling it to better withstand various dynamic loads during vehicle operation, thereby improving the overall vehicle handling performance and driving safety.

[0048] 2) Lightweight design: Aluminum alloy is used as the material for the side floor body. Through reasonable structural layout and the setting of reinforcing rib components 20, the weight of the side floor can be reduced while ensuring structural strength. This helps to improve the fuel economy of the vehicle and meets the current trend of environmental protection and energy conservation and emission reduction.

[0049] 3) Improved production and assembly efficiency: The integrated casting process simplifies the production process of the side floor body 10, reduces the need to assemble multiple parts, thereby improving production efficiency and reducing manufacturing costs. It also facilitates rapid installation on the assembly line, shortening the overall vehicle assembly time.

[0050] 4) By adding a partition plate in the middle of the chamber, the mold can be demolded on both the moving and stationary sides of the suspension mounting point, which can reduce the maximum wall thickness of the structure and the maximum demolding depth, thereby improving the mold strength and demolding difficulty.

[0051] 5) Improve the efficiency of cab layout space utilization: The reinforced chamber 102 is formed between the first side panel 13 and the second side panel 14, which not only enhances the lateral support capacity of the side floor, but also provides space for the arrangement of equipment and pipelines in the cab, which is conducive to optimizing the internal layout of the cab and improving space utilization.
