[0013] The first sill assembly is connected to the first seat mounting bracket and the third seat mounting bracket respectively;

[0014] The second sill assembly is connected to the second seat mounting bracket and the fourth seat mounting bracket, respectively.

[0015] In one possible implementation, the reinforcing cavity is a rectangular cavity.

[0016] In one possible implementation, the floor assembly further includes a plurality of connecting brackets, all located within the reinforcing cavity, with each connecting bracket having its two ends connected to the first crossbeam assembly and the second crossbeam assembly, respectively.

[0021] In one possible implementation, the floor assembly further includes a first longitudinal beam, a second longitudinal beam, and a central channel connecting plate. The first longitudinal beam, the second longitudinal beam, and the central channel connecting plate are all located on the side of the first crossbeam assembly away from the longitudinal beam. The central channel connecting plate is located between the first longitudinal beam and the second longitudinal beam. The first longitudinal beam, the second longitudinal beam, and the central channel connecting plate are respectively connected to the floor.

[0060] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0061] This disclosure provides a floor assembly for a vehicle, such as... Figure 1 As shown, the floor assembly includes a floor 1, a first crossbeam assembly 2, a second crossbeam assembly 3, a first threshold assembly 4, and a second threshold assembly 5.

[0062] The first crossbeam assembly 2 and the second crossbeam assembly 3 are arranged in parallel on the top surface of the floor 1, and both the first crossbeam assembly 2 and the second crossbeam assembly 3 are hollow structures. The first threshold assembly 4 is located on the first side of the floor 1 and is connected to the first end of the first crossbeam assembly 2 and the first end of the second crossbeam assembly 3, respectively. The second threshold assembly 5 is located on the second side of the floor 1 and is connected to the second end of the first crossbeam assembly 2 and the second end of the second crossbeam assembly 3, respectively. A reinforcing cavity 200 is formed between the first crossbeam assembly 2, the second crossbeam assembly 3, the first threshold assembly 4 and the second threshold assembly 5.

[0063] In this way, the reinforcing cavity 200 formed by the first crossbeam assembly 2, the second crossbeam assembly 3, the first sill assembly 4, and the second sill assembly 5 can effectively improve the structural rigidity of the floor assembly. In the event of a collision, the first crossbeam assembly 2, the second crossbeam assembly 3, the first sill assembly 4, and the second sill assembly 5 can serve as force transmission paths, improving the force transmission effect. Furthermore, since the first crossbeam assembly 2 and the second crossbeam assembly 3 are both hollow structures, they do not significantly increase the overall mass of the floor assembly, thus avoiding an excessive increase in vehicle energy consumption.

[0064] According to experimental data, using the technical solution provided in this disclosure embodiment, the torsional stiffness of the floor assembly is increased by 8%, the modal frequency is increased by 1.5Hz, and the safety collision performance is improved by 12%.

[0065] The following section provides a detailed explanation of the floor structure, using a new energy vehicle as an example:

[0066] Floor 1

[0067] Floor 1 is a component in the floor assembly used to connect the first crossbeam assembly 2, the second crossbeam assembly 3, the first threshold assembly 4, and the second threshold assembly 5.

[0068] See Figure 1 Floor 1 is a rectangular plate structure with a top surface and a bottom surface. The driver's cabin of the vehicle is located above the top surface, and the vehicle's battery is located below the floor 1.

[0069] In some possible embodiments, the floor 1 has raised reinforcing ribs 100 for increasing rigidity.

[0070] like Figure 1 As shown, the floor 1 has multiple raised reinforcing ribs 100. Specifically, the raised reinforcing ribs 100 can be formed by a stamping process, see [reference]. Figure 1 The raised reinforcing rib 100 can be raised from the bottom surface to the top surface.

[0071] Optionally, the multiple raised reinforcing ribs 100 can be distributed in a matrix. This allows the multiple raised reinforcing ribs 100 to be evenly distributed across the entire top surface of the floor 1, thereby improving the overall strength of the floor 1.

[0072] The shape of the raised reinforcing rib 100 can be a long rectangular strip or a circle. In the embodiments of this disclosure, the shapes of these raised reinforcing ribs 100 can be the same or different, and this disclosure does not limit them.

[0073] In some possible embodiments, floor 1 comprises a plurality of panels.

[0074] like Figure 1 As shown, the floor 1 includes a first plate 11 and a second plate 12. Both the first plate 11 and the second plate 12 are rectangular plate structures. The first plate 11 and the second plate 12 are partially stacked in the direction from the first beam assembly 2 to the second beam assembly 3.

[0075] In this example, the aforementioned stacked portion can improve the overall rigidity of the floor 1, and by setting the floor 1 to consist of two plates, the first plate 11 and the second plate 12, the processing and forming difficulty of the floor 1 can be reduced.

[0076] like Figure 2 As shown, the first plate 11 is a rectangular plate structure. The first plate 11 has a first flange structure 111 on both sides. The first flange structure 111 is formed by folding the edge portion of the first plate 11. The first flange structure 111 can be used to connect with the first threshold assembly 4 and the second threshold assembly 5 to improve the connection stability between the first threshold assembly 4 and the second threshold assembly 5 and the floor 1.

[0077] Specifically, see Figure 2 The first plate 11 has a plurality of first protruding reinforcing ribs 101, which are distributed in a matrix. The first protruding reinforcing ribs 101 can protrude from the bottom surface to the top surface of the first plate 11.

[0078] like Figure 3 As shown, the second plate 12 is a rectangular plate structure. The second plate 12 has a second flange structure 121 on both sides. The second flange structure 121 is formed by folding the edge portion of the second plate 12. One side of the second flange structure 121 can be used to connect with the first flange structure 111, and the other side can be used to connect with the first threshold assembly 4 and the second threshold assembly 5 to improve the connection stability between the first threshold assembly 4 and the second threshold assembly 5 and the floor 1.

[0079] Specifically, see Figure 3 The second plate 12 has a plurality of second protruding reinforcing ribs 102, which are distributed in a matrix. The second protruding reinforcing ribs 102 can protrude from the bottom surface to the top surface of the second plate 12.

[0080] In one example, such as Figure 2 As shown, the first plate 11 has multiple spaced-apart first protruding reinforcing ribs 101 on one side edge of the first plate 11, and the first protruding reinforcing ribs 101 are connected to the side edge of the first plate 11. That is, one side of the groove of the first protruding reinforcing rib 101 is a through-slot structure, and this through-slot structure is connected to the side edge of the first plate 11. Further, see... Figure 3 The second plate 12 has multiple spaced second raised reinforcing ribs 102 on one side edge of the second plate 12, and the second raised reinforcing ribs 102 are connected to the side edge of the second plate 12. That is, the groove side of the second raised reinforcing rib 102 is a through groove structure, and the through groove structure is connected to the side edge of the second plate 12.

[0081] In practice, the shape and size of the second protruding reinforcing rib 102 and the first protruding reinforcing rib 101 can be matched so that the second protruding reinforcing rib 102 can extend into the groove side of the first protruding reinforcing rib 101, thereby improving the overall rigidity of the floor 1.

[0082] Using the same technical solution as the embodiments of this disclosure, in the floor 1, the raised reinforcing ribs 100 all protrude towards the top surface. Thus, the raised reinforcing ribs 100 will not occupy the arrangement space of the battery below. For the entire floor assembly, the force transmission structures such as the first crossbeam assembly 2 are arranged on the top surface of the floor 1. This makes the west side of the floor 1 very flat, which can provide the maximum arrangement space for the new energy battery, increase the battery capacity and the range of the new energy vehicle.

[0083] First crossbeam assembly 2 and second crossbeam assembly 3

[0084] The first crossbeam assembly 2 and the second crossbeam assembly 3 are components in the floor assembly used to increase rigidity.

[0085] like Figure 1 As shown, the first crossbeam assembly 2 and the second crossbeam assembly 3 are both arranged on the top surface of the floor 1. Specifically, the first crossbeam assembly 2 and the second crossbeam assembly 3 can both be arranged on the top surface of the first plate 11, and the first crossbeam assembly 2 and the second crossbeam assembly 3 are parallel to each other.

[0086] In some possible embodiments, such as Figure 4 As shown, the first crossbeam assembly 2 includes a first crossbeam body 21, a first seat mounting bracket 22, and a second seat mounting bracket 23. The first crossbeam body 21 is fixed to the top surface of the floor 1. The first seat mounting bracket 22 is located at the first end of the first crossbeam body 21 and is detachably connected to the first crossbeam body 21. The second seat mounting bracket 23 is located at the second end of the first crossbeam body 21 and is detachably connected to the first crossbeam body 21. The second crossbeam assembly 3 includes a second crossbeam body 31, a third seat mounting bracket 32, and a fourth seat mounting bracket 33. The second crossbeam body 31 is fixed to the top surface of the floor 1. The third seat mounting bracket 32 ​​is located at the first end of the second crossbeam body 31 and is detachably connected to the second crossbeam body 31. The fourth seat mounting bracket 33 is located at the second end of the second crossbeam body 31 and is detachably connected to the second crossbeam body 31.

[0087] The first sill assembly 4 is connected to the first seat mounting bracket 22 and the third seat mounting bracket 32, respectively, and the second sill assembly 5 is connected to the second seat mounting bracket 23 and the fourth seat mounting bracket 33, respectively.

[0088] For example, the first seat mounting bracket 22 and the second seat mounting bracket 23 can both be detachably connected to the first crossbeam body 21 by bolts, and the third seat mounting bracket 32 ​​and the fourth seat mounting bracket 33 can both be detachably connected to the second crossbeam body 31 by bolts.

[0089] By adopting the technical solution provided in this disclosure, the first crossbeam assembly 2 is configured as a segmented first crossbeam body 21, a first seat mounting bracket 22, and a second seat mounting bracket 23, and the second crossbeam assembly 3 is configured as a segmented second crossbeam body 31, a third seat mounting bracket 32, and a fourth seat mounting bracket 33. For vehicles with different wheelbase widths, only the mounting brackets of different sizes need to be replaced accordingly to achieve the replacement of the floor assembly, thereby realizing the universal development of the floor assembly. This can minimize the development cost of the floor structure. Currently, the floor assembly provided in this disclosure can be used in four different wheelbase models.

[0090] Figure 5 This is a schematic diagram of the structure of a first crossbeam body 21 provided in an embodiment of this disclosure. Figure 6 This is a schematic cross-sectional view of a first crossbeam body 21 provided in an embodiment of this disclosure. Figure 5 and Figure 6 As shown, the cross-section of the first crossbeam body 21 is in a U-shape, and the top surface of the first crossbeam body 21 has a plurality of recessed reinforcing ribs, which are spaced along the extending direction of the first crossbeam body 21.

[0091] Exemplarily, the top surface of the first crossbeam body 21 has three recessed reinforcing ribs. The recessed reinforcing rib in the middle is symmetric about the cross-section of the first crossbeam body 21, and the recessed reinforcing ribs on both sides are symmetric about the cross-section of the first crossbeam body 21.

[0092] In this way, by providing the recessed reinforcing ribs, the stiffness of the first crossbeam body 21 can be improved. The three recessed reinforcing ribs on the top surface of the first crossbeam body 21 are symmetric about the cross-section of the first crossbeam body 21, which can avoid uneven stiffness distribution of the first crossbeam body 21.

[0093] Figure 7 FIG. is a schematic structural view of a second crossbeam body 31 provided by an embodiment of the present disclosure. Figure 8 FIG. is a schematic cross-sectional view of a second crossbeam body 31 provided by an embodiment of the present disclosure. As Figure 7 and Figure 8 shown, the second crossbeam body 31 includes a connecting portion 311, a first bending portion 312 and a second bending portion 313. The connecting portion 311 is used to connect with the floor 1. The first bending portion 312 is connected to one side of the connecting portion 311. After the first bending portion 312 is bent three times in opposite directions in sequence, it is connected to the surface of the connecting portion 311 away from the floor 1. A first cavity structure 314 is formed between the first bending portion 312 and the connecting portion 311. The second bending portion 313 is connected to the other side of the connecting portion 311. After the second bending portion 313 is bent twice in opposite directions in sequence, it is connected to the first bending portion 312, and the end of the second bending portion 313 is connected to the area between the second bending position and the third bending position of the first bending portion 312. A second cavity structure 315 is formed among the second bending portion 313, the first bending portion 312 and the connecting portion 311, and the second cavity structure 315 is not communicated with the above-mentioned first cavity structure 314.

[0094] Exemplarily, referring to Figure 8 , the cross-section of the second crossbeam body 31 is in an 8-shape.

[0095] Adopting the technical solution provided by the embodiment of the present disclosure, the second crossbeam body 31 has two non-communicating cavity structures inside, making the second crossbeam body 31 a hollow structure, so that the stiffness can be improved without significantly increasing the mass.

[0096] Figure 9 FIG. is a schematic structural view of a first seat mounting bracket 22 provided by an embodiment of the present disclosure. As Figure 9 As shown, the first seat mounting bracket 22 also has a U-shaped structure. One side of the first seat mounting bracket 22 has multiple first connecting flanges 22a, which are used to connect with the first sill assembly 4 to improve the connection stability between the first crossbeam assembly 2 and the first sill assembly 4. The structure of the second seat mounting bracket 23 can refer to the structure of the first seat mounting bracket 22 described above, and will not be repeated here.

[0097] Figure 10 This is a schematic diagram of the structure of a third seat mounting bracket 32 ​​provided in an embodiment of this disclosure, as shown below. Figure 10 As shown, the third seat mounting bracket 32 ​​also has a U-shaped structure. One side of the third seat mounting bracket 32 ​​has multiple second connecting flanges 32a, which are used to connect with the first sill assembly 4 to improve the connection stability between the second crossbeam assembly 3 and the first sill assembly 4. The structure of the fourth seat mounting bracket 33 can refer to the structure of the third seat mounting bracket 32 ​​described above, and will not be repeated here.

[0098] In practice, different models of seat mounting brackets can be produced for vehicles with different wheelbases. This eliminates the need to redesign and process the crossbeam body, thus improving the versatility of the first crossbeam assembly 2 and the second crossbeam assembly 3.

[0099] In some possible embodiments, the floor assembly also includes a plurality of connecting brackets 6.

[0100] like Figure 1 As shown, multiple connecting brackets 6 are located within the reinforcing cavity 200, and the two ends of each connecting bracket 6 are connected to the first crossbeam assembly 2 and the second crossbeam assembly 3, respectively.

[0101] In one example, multiple connecting brackets are parallel to each other in six phases.

[0102] Optionally, the plurality of connecting brackets 6 may include a first connecting bracket 61 and a second connecting bracket 62, see [link to documentation]. Figure 1 The floor assembly includes a first connecting bracket 61 and four second connecting brackets 62. The four second connecting brackets 62 are distributed on both sides of the first connecting bracket 61. Each side of the first connecting bracket 61 has two second connecting brackets 62. The distance from the first connecting bracket 61 to the first threshold assembly 4 and the second threshold assembly 5 is equal. Each pair of second connecting brackets 62 is symmetrically distributed about the first connecting bracket 61.

[0103] For example, see Figure 1The first connecting bracket 61 has a plate-like structure, with recessed reinforcing ribs and multiple protruding reinforcing ribs. The recessed reinforcing ribs are located in the middle of the first connecting bracket 61, and the protruding reinforcing ribs are distributed circumferentially around the recessed reinforcing ribs. This allows the first connecting bracket 61 to have high rigidity.

[0104] Furthermore, each recessed or raised reinforcing rib has a mounting hole at its top, which provides assembly space for other vehicle components, thereby improving the vehicle's space utilization.

[0105] For example, see Figure 12 The second connecting bracket 62 has a plate-like structure, and the middle part of the second connecting bracket 62 protrudes to form a raised reinforcing rib, which is used to improve the rigidity of the second connecting bracket 62.

[0106] In one example, both the first connecting bracket 61 and the second connecting bracket 62 are formed by a stamping process.

[0107] In some possible embodiments, the floor assembly also includes a first longitudinal beam 7, a second longitudinal beam 8, and a central channel connecting plate 9.

[0108] See Figure 1 The first longitudinal beam 7, the second longitudinal beam 8, and the middle channel connecting plate 9 are all located on the side of the first crossbeam assembly 2 away from the second crossbeam assembly 3. The middle channel connecting plate 9 is located between the first longitudinal beam 7 and the second longitudinal beam 8. The first longitudinal beam 7, the second longitudinal beam 8, and the middle channel connecting plate 9 are respectively connected to the floor 1.

[0109] Specifically, such as Figure 11 As shown, one end of the first longitudinal beam 7 is connected to the floor 1, and the other end is used to connect to the front bulkhead of the vehicle. The middle of the first longitudinal beam 7 has a recessed reinforcing rib, which is used to improve the rigidity of the first longitudinal beam 7. The specific structure of the second longitudinal beam 8 can be referred to the structure of the first longitudinal beam 7, and will not be described again here.

[0110] In one example, such as Figure 11 As shown, the end of the first longitudinal beam 7 connected to the floor 1 has a third flange structure 71, which is used to connect to the first crossbeam body 21 in the first crossbeam assembly 2. This improves the connection stability between the first longitudinal beam 7 and the first crossbeam assembly 2.

[0111] like Figure 12 As shown, one end of the central channel connecting plate 9 is connected to the floor 1, and the other end is used to connect to the front bulkhead of the vehicle. The middle part of the first longitudinal beam 7 has a recessed reinforcing rib, which is used to improve the rigidity of the central channel connecting plate 9.

[0112] Unless otherwise specified, the connection between the components shown in the embodiments of this disclosure may be one or more of the following processes: spot welding, CO2 welding, riveting, bolting, bonding, and self-piercing riveting. The embodiments of this disclosure do not limit this process.

[0113] The components shown in the embodiments of this disclosure may be made of metallic or polymeric materials, such as steel, aluminum alloy, or engineering plastics. Those skilled in the art can make their own settings according to actual needs, and the embodiments of this disclosure do not limit this.

[0114] For the components shown in the embodiments of this disclosure, the thickness can be set by a technician according to actual needs, and the embodiments of this disclosure do not limit this.

[0115] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0116] This disclosure provides a floor assembly in which the first crossbeam assembly 2 and the second crossbeam assembly 3 are both hollow structures. A reinforcing cavity 200 is formed between the first crossbeam assembly 2, the second crossbeam assembly 3, the first sill assembly 4, and the second sill assembly 5. This reinforcing cavity 200 effectively improves the structural rigidity of the floor assembly. In the event of a collision, the first crossbeam assembly 2, the second crossbeam assembly 3, the first sill assembly 4, and the second sill assembly 5 can serve as force transmission paths, improving force transmission efficiency. Furthermore, since the first crossbeam assembly 2 and the second crossbeam assembly 3 are both hollow structures, the overall mass of the floor assembly is not significantly increased, thus avoiding an excessive increase in vehicle energy consumption.

[0117] This disclosure provides a vehicle that includes the floor assembly described above.
