[0028] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

In the description of this application, unless otherwise stated, "multiple" means two or more. Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In the prior art, the front floor assembly includes a front floor with a raised section in the middle, and a seat crossbeam crosses the raised section and connects to the front floor. Since both the front floor and the seat crossbeam are made of steel, although the front floor assembly has high strength, the connection structure is relatively complex because the seat crossbeam crosses the raised section and connects to the front floor. Secondly, the overall weight of the front floor assembly is relatively large, which is not conducive to vehicle lightweighting.

[0033] The front floor assembly and vehicle provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0034] like Figures 1 to 6As shown in the embodiment of this application, a front floor assembly is proposed, including: a front floor 10, a seat crossbeam 20, and a connector 30; the front floor assembly has a first direction X and a second direction Y that are perpendicular to each other, the connector 30 includes a main body 31 and a connecting part 32 disposed on at least one side of the main body 31 along the second direction Y, the main body 31 is disposed on the front floor 10 and connected to the front floor 10; the seat crossbeam 20 is disposed on the front floor 10 and connected to the connecting part 32.

[0035] It should be noted that, as Figure 1 As shown, the first direction X is the extension direction of the protrusion 11, and the second direction Y is the extension direction of the seat beam 20.

[0036] In this embodiment, the connecting portion 32 of the connector 30 and the seat crossbeam 20 are respectively provided on the front floor 10, and the main body 31 and the seat crossbeam 20 are connected by the connecting portion 32. This simplifies the connection structure between the seat crossbeam 20 and the front floor 10, making installation easier.

[0037] In some embodiments, such as Figure 1 As shown, there are four seat crossbeams 20, two of which are located on one side of the connector 30 along the second direction Y, and the remaining two are located on the other side of the connector 30 along the second direction Y. The connector 30 includes four connecting parts 32, with two connecting parts 32 on each side of the main body 31 along the second direction Y, and each connecting part 32 is connected to one seat crossbeam 20.

[0038] In specific applications, the front floor 10 can be made of stamped aluminum alloy panel, and the seat crossbeam 20 can be made of extruded aluminum. In this way, compared with the existing technology that uses high-strength hot-formed steel stamped seat crossbeam 20 and steel front floor 10, this application reduces the weight of the front floor assembly while meeting structural strength requirements, achieving a balance between lightweight and strength.

[0039] Optionally, such as Figures 1 to 3 as well as Figure 6 As shown, the front floor 10 has a protrusion 11 extending along the first direction X, and a hollow channel 12 is formed in the front floor 10 at a position corresponding to the protrusion 11; the main body 31 is provided on the protrusion 11 and connected to the protrusion 11.

[0040] In this embodiment, a protrusion 11 extending along the first direction X is provided in the front floor 10, and a hollow channel 12 is formed at a position corresponding to the protrusion 11. The main body 31 is disposed on and connected to the protrusion 11. This increases the contact area between the main body 31 and the front floor 10 through the protrusion 11, improving connection stability. In addition, the design of the hollow channel 12 not only enhances the rigidity and torsional resistance of the front floor 10, but also reduces the overall weight by reducing material usage. Furthermore, the load of the seat beam 20 can be directly transferred to the hollow channel 12 area of ​​the front floor 10 through the connector 30, reducing the need for additional reinforcement.

[0041] Optionally, such as Figure 1 and Figure 3 As shown, the main body 31 includes a first connecting segment 311 and a second connecting segment 312 that are interconnected along a first direction X; the first connecting segment 311 is disposed on and connected to the protrusion 11, and the connecting segment 32 is disposed on at least one side of the first connecting segment 311 along a second direction Y; the second connecting segment 312 is disposed on another part of the protrusion 11 and connected to the protrusion 11, and the end of the first connecting segment 311 away from the second connecting segment 312 is adapted to be connected to the front bulkhead.

[0042] In this embodiment, a first connecting segment 311 is disposed on and connected to a portion of the protrusion 11, and a connecting portion 32 is disposed on at least one side of the first connecting segment 311 along the second direction Y; a second connecting segment 312 is disposed on another portion of the protrusion 11 and connected to it, and the end of the first connecting segment 311 away from the second connecting segment 312 is adapted to connect to the front bulkhead. This allows the load to be transferred to the front floor 10 and the front bulkhead respectively through the first connecting segment 311 and the second connecting segment 312, avoiding load concentration in a single area and resulting in a more uniform load distribution.

[0043] In specific applications, the first connecting segment 311 and the second connecting segment 312 can be detachably connected, threaded, or snap-fit ​​connected. Those skilled in the art can make the settings according to actual needs, and this application does not impose any restrictions on this.

[0044] Understandably, the first connecting segment 311 and the second connecting segment 312 are detachably connected, which facilitates the actual installation process by first installing the first connecting segment 311 on the protrusion 11, then installing the second connecting segment 312 on the protrusion 11, and finally connecting it to the first connecting segment 311, thereby facilitating disassembly, maintenance, and installation.

[0045] It should be explained that the first connecting segment 311 and the second connecting segment 312 are respectively adapted to the size and shape of the corresponding protrusion 11 to avoid occupying too much space.

[0046] Optionally, the connecting part 32 and the first connecting section 311 are an integral structure.

[0047] In this embodiment, the connecting portion 32 and the first connecting segment 311 are designed as an integral structure. This enhances the connection strength between the connecting portion 32 and the first connecting segment 311, enabling the front floor assembly to better withstand vibration and impact loads and reducing structural problems caused by connection failure. Furthermore, the integral structure allows for more direct and efficient force transmission between the connecting portion 32 and the first connecting segment 311, reducing stress concentration caused by discontinuities at the connection interface and enhancing the overall structural rigidity and fatigue resistance.

[0048] Optionally, the first connecting segment 311 and the second connecting segment 312 are separate structures.

[0049] In this embodiment, the first connecting segment 311 and the second connecting segment 312 are configured as separate structures. This separate design allows each part to be installed or manufactured independently, improving modularity and reducing processing difficulty.

[0050] In some embodiments, the split structure design allows the first connecting segment 311 and the second connecting segment 312 to use different materials or manufacturing processes, thereby optimizing manufacturing costs. For example, the first connecting segment 311 may be made of a high-strength material to withstand larger loads, while the second connecting segment 312 may be made of a lightweight material to reduce weight; for instance, the first connecting segment 311 may be cast using a high-strength hot-formed steel casting process, while the second connecting segment 312 may be manufactured using an aluminum extrusion process.

[0051] Optionally, such as Figure 5 and Figure 6 As shown, at least part of the end of the connecting part 32 away from the main body part 31 overlaps with the seat crossbeam 20.

[0052] In this embodiment, the end of the connecting portion 32 furthest from the main body 31 is at least partially overlapped with the seat crossbeam 20. This creates an overlapping connection structure between the connecting portion 32 and the seat crossbeam 20, increasing the contact area between them. This allows the load to be distributed more evenly over the overlapping area, reducing localized stress concentration. Simultaneously, the overlapping structure provides additional friction, further enhancing the stability of the connection.

[0053] In some embodiments, the connection between the connecting part 32 and the seat crossbeam 20 can be tightened with flow drill screws (FDS) or bolts, and this application embodiment does not limit this.

[0054] Optionally, such as Figure 5As shown, the front floor 10 also includes a front floor body 14 and a first reinforcing rib 13; the front floor body 14 has a hollow channel 12 formed at a position corresponding to the protrusion 11, and the first reinforcing rib 13 is disposed in the hollow channel 12 and connected to the front floor body 14.

[0055] In this embodiment, the first reinforcing rib 13 is disposed within the hollow channel 12 and connected to the front floor body 14 to form a hollow structure. Thus, the rigidity and torsional resistance of the hollow channel 12 are significantly enhanced through the supporting effect of the first reinforcing rib 13. Furthermore, the hollow structure reduces weight while further improving the bending and torsional resistance of the front floor 10 through geometric optimization (such as a triangular or honeycomb structure).

[0056] In some embodiments, such as Figure 5 As shown, the third direction Z is the direction in which the seat beam 20 and the front floor 10 are arranged opposite each other. The hollow channel 12 can be closed or open in the third direction Z. This embodiment of the application does not impose any restrictions here.

[0057] With the hollow channel 12 closed, one end of the first reinforcing rib 13 is connected to the protrusion 11, and the other end is connected to the front floor 10. This allows the reinforcing rib to evenly distribute the load transmitted by the seat beam 20 and other components to a larger area of ​​the front floor 10, and to efficiently transfer the load to other parts of the vehicle body through the structural characteristics of the hollow channel 12, reducing energy loss and improving the overall transmission efficiency of the structure.

[0058] Optionally, such as Figure 1 and Figure 5 As shown, the seat crossbeam 20 includes a seat crossbeam body 21 and a second connecting portion 211 disposed on at least one side of the seat crossbeam body 21 along the first direction X; the second connecting portion 211 is connected to the front floor 10, the seat crossbeam body 21 extends along the second direction Y, and one end of the seat crossbeam body 21 is connected to the connecting portion 32.

[0059] In this embodiment, a multi-point fixing structure is formed by connecting the second connecting part 211 to the front floor 10 and connecting one end of the seat beam body 21 to the connecting part 32. This design makes the connection between the seat beam 20 and the front floor 10 more stable, reducing the risk of loosening or failure due to a single connection point. The second connecting part 211 further distributes the load, making the connection more uniform and reliable.

[0060] In some embodiments, such as Figure 1As shown, the second connecting part 211 and the front floor 10 can be connected using self-piercing riveting (SPR) technology. SPR is a novel connection method that uses a hydraulic cylinder or servo motor to power and directly press rivets into the plates to be riveted. Compared with traditional welding and bolting methods, SPR technology has advantages such as higher connection efficiency, lower cost, and less damage to materials. It can achieve a strong connection between plates without generating heat or changing the original properties of the materials.

[0061] In specific applications, the connection between the connector 30 and the front floor 10 can also adopt SPR connection technology. Those skilled in the art can set it according to actual needs, and this application does not limit it.

[0062] Optionally, the front floor assembly also has a third direction Z perpendicular to the first direction X and the second direction Y respectively, and the ratio between the length of the seat beam body 21 along the first direction X and the width of the seat beam body 21 along the third direction Z satisfies the range of 2-2.5.

[0063] In this embodiment, the ratio between the length of the seat beam body 21 along the first direction X and the width of the seat beam body 21 along the third direction Z is set within a certain range. This avoids the situation where the ratio is too small, resulting in insufficient structural strength of the seat beam 20, and avoids the situation where the ratio is too large, resulting in excessive material usage for the seat beam 20.

[0064] For example, the ratio can be set to any value between 2, 2.1, 2.2, 2.3, 2.4, and 2.5, or any range between two values.

[0065] Optionally, such as Figure 6 As shown, the seat crossbeam 20 also includes a second reinforcing rib 23; the seat crossbeam body 21 has a cavity 22; the second reinforcing rib 23 is located in the cavity 22 and connected to the seat crossbeam body 21.

[0066] In this embodiment, by placing the second reinforcing rib 23 within the cavity 22 and connecting it to the seat crossbeam body 21 to form a hollow structure, the rigidity and torsional resistance of the cavity 22 are significantly enhanced through the supporting effect of the second reinforcing rib 23. Furthermore, the hollow structure reduces weight while further improving the bending and torsional resistance of the seat crossbeam 20 through geometric optimization (such as a triangular or honeycomb structure).

[0067] It is understood that the seat crossbeam 20 has a protrusion, which corresponds to the cavity 22; the cavity 22 can be closed or open in the third direction Z; the embodiments of this application are not limited here.

[0068] In some embodiments, with the cavity 22 closed, one end of the second reinforcing rib 23 is connected to the protrusion of the seat crossbeam 20, and the other end is connected to the seat crossbeam 20. This allows the reinforcing rib to evenly distribute the load transmitted by the seat crossbeam 20 and other components to a larger area of ​​the front floor 10, and to efficiently transmit the load to other parts of the vehicle body through the structural characteristics of the hollow channel 12, reducing energy loss and improving the overall transmission efficiency of the structure.

[0069] Optionally, such as Figures 1 to 3 As shown, the front floor assembly also includes a reinforcing beam 40; the reinforcing beam 40 is disposed on the front floor 10, one end of the reinforcing beam 40 is connected to the seat crossbeam 20, the other end of the reinforcing beam 40 extends away from the seat crossbeam 20 along the first direction X, and the other end of the reinforcing beam 40 is adapted to be connected to the front bulkhead.

[0070] In this embodiment, a reinforcing beam 40 is disposed on the front floor 10. One end of the reinforcing beam 40 is connected to the seat crossbeam 20, and the other end of the reinforcing beam 40 extends away from the seat crossbeam 20 along a first direction X. The other end of the reinforcing beam 40 is adapted to be connected to the front bulkhead. Thus, the rigid connection of the reinforcing beam 40 significantly enhances the overall rigidity and torsional resistance of the front floor assembly. Furthermore, the reinforcing beam 40 can transfer the loads of the seat crossbeam 20 and the front bulkhead to a larger area of ​​the front floor 10, reducing local stress concentration and optimizing the load distribution path.

[0071] like Figure 1 and Figure 3 As shown, the number of reinforcing beams 40 can be set to two, with each reinforcing beam 40 connected to a corresponding seat crossbeam 20. Of course, the number of reinforcing beams 40 can also be set to three, four, etc., and those skilled in the art can set it according to actual needs; this application does not limit this.

[0072] Optionally, such as Figures 1 to 4 As shown, it also includes a seat mounting component 50; the seat mounting component 50 is connected to the seat crossbeam 20 and / or the connecting part 32, and the seat mounting component 50 is used to mount the seat.

[0073] In this embodiment, the seat mounting component 50 is used to mount the seat by connecting the seat mounting component to the seat crossbeam 20 and / or the connecting portion 32. This significantly enhances the stability of the seat installation through the rigid support of the seat crossbeam 20 and the connecting portion 32. Furthermore, the multi-point connection design between the seat mounting component 50 and the seat crossbeam 20 and the connecting portion 32 further distributes the load on the seat, reducing localized stress concentration.

[0074] Understandably, such as Figure 1As shown, eight seat mounting pieces 50 can be provided, four seat crossbeams 20 and four connecting parts 32; each seat crossbeam 20 has a seat mounting piece 50 at the end away from the protrusion 11, and each connecting part 32 has a seat mounting piece 50 at the end near the main body 31. In this way, placing the seat mounting pieces 50 in different locations helps to evenly distribute the load transmitted from the seat.

[0075] Of course, the number of seat mounting parts 50 can also be set to other quantities, and those skilled in the art can set them according to actual needs. This application does not limit this.

[0076] It should be noted that the seat mounting component 50 can be an aluminum alloy seat bracket or a steel structure seat bracket. Those skilled in the art can set it according to actual needs, and this application does not impose any restrictions on it.

[0077] Optionally, embodiments of this application also propose a vehicle including the front floor assembly described in the above embodiments.

[0078] In this embodiment, the connecting portion 32 and the main body 31 of the connector 30, as well as the seat crossbeam 20, are respectively provided on the front floor 10, and the main body 31 and the seat crossbeam 20 are connected by the connecting portion 32. This simplifies the connection structure between the seat crossbeam 20 and the front floor 10, making installation easier.
