[0060] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0061] The present disclosure provides a vehicle floor assembly, such as Figure 1 As shown, the floor assembly includes a floor 1 , a first cross beam assembly 2 , a second cross beam assembly 3 , a first door sill assembly 4 and a second door sill 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 the first crossbeam assembly 2 and the second crossbeam assembly 3 are both hollow structures. The first threshold assembly 4 is located on the first side of the floor 1, and is respectively connected to the first end of the first crossbeam assembly 2 and the first end of the second crossbeam assembly 3. The second threshold assembly 5 is located on the second side of the floor 1, and is respectively connected to the second end of the first crossbeam assembly 2 and the second end of the second crossbeam assembly 3. A reinforcement 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 reinforcement cavity 200 formed by the first cross beam assembly 2, the second cross beam assembly 3, the first threshold assembly 4 and the second threshold assembly 5 can effectively improve the structural rigidity of the floor assembly. When a collision occurs, the first cross beam assembly 2, the second cross beam assembly 3, the first threshold assembly 4 and the second threshold assembly 5 can serve as a force transmission path to improve the force transmission effect. In addition, since the first cross beam assembly 2 and the second cross beam assembly 3 are both hollow structures, the overall mass of the floor assembly will not be greatly increased, and therefore the energy consumption of the vehicle will not be excessively increased.

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

[0065] Below, taking the vehicle as a new energy vehicle as an example, the structure of the floor structure is introduced in detail:

[0066] Floor 1

[0067] The floor panel 1 is a component in the floor panel assembly used to connect the first cross beam assembly 2, the second cross beam assembly 3, the first door sill assembly 4, the second door sill assembly 5 and other components.

[0068] See also Figure 1 The floor 1 is a rectangular plate structure, and the floor 1 has a top surface and a bottom surface, wherein the top surface is the driving cabin of the vehicle, and the bottom surface of the floor 1 is the battery of the vehicle.

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

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

[0071] Optionally, the plurality of raised reinforcing ribs 100 may be distributed in a matrix, so that the plurality of raised reinforcing ribs 100 are evenly distributed on the entire top surface of the floor 1 , thereby improving the overall strength of the floor 1 .

[0072] The shape of the raised reinforcing ribs 100 may be a long rectangular strip or a circular strip. In the embodiment of the present disclosure, the shapes of these raised reinforcing ribs 100 may be the same or different, and the embodiment of the present disclosure does not limit this.

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

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

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

[0076] like Figure 2 As shown, the first plate body 11 is a rectangular plate structure, and both sides of the first plate body 11 have a first flange structure 111. The first flange structure 111 is formed by folding the edge portion of the first plate body 11. The first flange structure 111 can be used to connect with the first threshold assembly 4 and the second threshold assembly 5 to enhance 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 body 11 has a plurality of first raised reinforcing ribs 101 , and the plurality of first raised reinforcing ribs 101 are distributed in a matrix manner. The first raised reinforcing ribs 101 may be raised from the bottom surface to the top surface of the first plate body 11 .

[0078] like Figure 3 As shown, the second plate body 12 is a rectangular plate structure, and both sides of the second plate body 12 have a second flange structure 121. The second flange structure 121 is formed by folding the edge portion of the second plate body 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 body 12 has a plurality of second raised reinforcing ribs 102 , and the plurality of second raised reinforcing ribs 102 are distributed in a matrix manner. The second raised reinforcing ribs 102 may be raised from the bottom surface to the top surface of the second plate body 12 .

[0080] In one example, if Figure 2 As shown, the first plate 11 has a plurality of first protruding reinforcing ribs 101 arranged at intervals on the edge of the first plate 11, and the first protruding reinforcing ribs 101 are connected to the edge of the first plate 11. That is, one side of the groove of the first protruding reinforcing rib 101 is a through groove structure, and the through groove structure is connected to the edge of the first plate 11. Further, see Figure 3 The second plate body 12 has a plurality of second raised reinforcing ribs 102 arranged at intervals on the edge of one side close to the second plate body 12, and the second raised reinforcing ribs 102 are connected to the edge of one side close to the second plate body 12. That is, one side of the groove of the second raised reinforcing rib 102 is a through groove structure, and the through groove structure is connected to the edge of one side close to the second plate body 12.

[0081] In practice, the shapes and sizes of the second raised reinforcing ribs 102 and the first raised reinforcing ribs 101 can be adapted to each other, so that the second raised reinforcing ribs 102 can extend into one side of the groove of the first raised reinforcing ribs 101 , thereby improving the overall rigidity of the floor 1 .

[0082] By adopting the same technical solution as the embodiment of the present disclosure, in the floor 1, the raised reinforcing ribs 100 all protrude toward the top surface, so that the raised reinforcing ribs 100 will not occupy the arrangement space of the batteries below. For the entire floor assembly, the first crossbeam assembly 2 and other force transmission structures are arranged on the top surface of the floor 1, which makes the west side of the floor 1 very flat, and can provide the maximum arrangement space for new energy batteries, thereby increasing the battery capacity and the endurance of new energy vehicles.

[0083] The first cross beam assembly 2 and the second cross beam assembly 3

[0084] The first cross-beam assembly 2 and the second cross-beam assembly 3 are components in the floor assembly for improving rigidity.

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

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

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

[0088] Exemplarily, the first seat mounting bracket 22 and the second seat mounting bracket 23 may be detachably connected to the first cross beam body 21 by bolts, and the third seat mounting bracket 32 ​​and the fourth seat mounting bracket 33 may be detachably connected to the second cross beam body 31 by bolts.

[0089] By adopting the technical solution provided by the embodiment of the present disclosure, by setting the first crossbeam assembly 2 as a first crossbeam body 21, a first seat mounting bracket 22, and a second seat mounting bracket 23 in a segmented form, and setting the second crossbeam assembly 3 as a second crossbeam body 31, a third seat mounting bracket 32, and a fourth seat mounting bracket 33 in a segmented form, for vehicles with different width wheelbases, only the mounting brackets of different sizes need to be replaced to realize the replacement of the floor assembly, thereby realizing the universal development of the floor assembly. The development cost of the floor structure can be reduced to the maximum extent. At present, the floor assembly provided by the embodiment of the present disclosure can be universally used for four models with different wheelbases.

[0090] Figure 5 is a structural schematic diagram of a first crossbeam body 21 provided in an embodiment of the present disclosure, Figure 6 is a cross-sectional schematic diagram of a first crossbeam body 21 provided in an embodiment of the present disclosure. Figure 5 and Figure 6 As shown, the cross section of the first beam body 21 is in a "X" shape, and the top surface of the first beam body 21 has a plurality of recessed reinforcing ribs, which are spaced apart along the extension direction of the first beam body 21 .

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

[0092] In this way, by setting recessed reinforcing ribs, the rigidity of the first beam body 21 can be improved. The three recessed reinforcing ribs on the top surface of the first beam body 21 are symmetrically located in the cross section of the first beam body 21, which can reduce the uneven rigidity distribution of the first beam body 21 on the wall surface.

[0093] Figure 7 is a structural schematic diagram of a second crossbeam body 31 provided in an embodiment of the present disclosure, Figure 8 is a cross-sectional schematic diagram of a second cross beam body 31 provided in an embodiment of the present disclosure. Figure 7 and Figure 8 As shown, the second cross beam 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 to the floor 1. The first bending portion 312 is connected to one side of the connecting portion 311. The first bending portion 312 is connected to the surface of the connecting portion 311 away from the floor 1 after being bent three times in opposite directions. 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. The second bending portion 313 is connected to the first bending portion 312 after being bent twice in opposite directions, 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 between the second bending portion 313, the first bending portion 312 and the connecting portion 311, and the second cavity structure 315 is not connected to the above-mentioned first cavity structure 314.

[0094] For example, see Figure 8 The cross section of the second beam body 31 is in an 8-shape.

[0095] By adopting the technical solution provided in the embodiment of the present disclosure, the second beam body 31 has two non-connected cavity structures inside, so that the second beam body 31 has a hollow structure, thereby improving the rigidity without significantly increasing the mass.

[0096] Fig. 9 is a schematic diagram of the structure of a first seat mounting bracket 22 provided in an embodiment of the present disclosure, such as Fig. 9 As shown, the first seat mounting bracket 22 also has a "J"-shaped structure, and one side of the first seat mounting bracket 22 has a plurality of first connecting flanges 22a, which are used to connect with the first threshold assembly 4 to improve the connection stability between the first crossbeam assembly 2 and the first threshold assembly 4. The structure of the second seat mounting bracket 23 can refer to the structure of the first seat mounting bracket 22, and will not be repeated here.

[0097] Fig.10 is a schematic diagram of the structure of a third seat mounting bracket 32 ​​provided in an embodiment of the present disclosure, such as Fig.10 As shown, the third seat mounting bracket 32 ​​also has a "J"-shaped structure, and one side of the third seat mounting bracket 32 ​​has a plurality of second connecting flanges 32a, which are used to connect with the first threshold assembly 4 to improve the connection stability between the second cross beam assembly 3 and the first threshold assembly 4. The structure of the fourth seat mounting bracket 33 can refer to the structure of the third seat mounting bracket 32, and will not be repeated here.

[0098] In practice, different types of seat mounting brackets can be produced for vehicles with different wheelbases. In this way, there is no need to redesign and process the crossbeam body, and the versatility of the first crossbeam assembly 2 and the second crossbeam assembly 3 can be improved.

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

[0100] like Figure 1 As shown, a plurality of connecting brackets 6 are located in the reinforcement cavity 200 , and 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, a plurality of connecting brackets 6 are parallel.

[0102] Optionally, the plurality of connecting brackets 6 may include a first connecting bracket 61 and a second connecting bracket 62, see 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 distances from the first connecting bracket 61 to the first threshold assembly 4 and the second threshold assembly 5 are equal, and each pair of second connecting brackets 62 are symmetrically distributed about the first connecting bracket 61.

[0103] For example, see Figure 1The first connecting bracket 61 has a plate-like structure, and has a concave reinforcing rib and a plurality of convex reinforcing ribs, wherein the concave reinforcing rib is located in the middle of the first connecting bracket 61, and the convex reinforcing ribs are distributed circumferentially around the concave reinforcing rib. In this way, the first connecting bracket 61 can have a higher rigidity.

[0104] Furthermore, a mounting hole is provided at the top of each recessed reinforcing rib or raised reinforcing rib, and the mounting hole is used to provide assembly space for other components of the vehicle, thereby improving the space utilization of the vehicle.

[0105] For example, see Fig.12 The second connecting bracket 62 has a plate-like structure, and a protrusion in the middle of the second connecting bracket 62 forms a protruding reinforcement rib for improving the rigidity of the second connecting bracket 62 .

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

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

[0108] See also 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 cross beam assembly 2 away from the second cross beam assembly 3, the middle channel connecting plate 9 is located between the first longitudinal beam 7 and the second longitudinal beam 8, and 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, Fig.11 As shown, one end of the first longitudinal beam 7 is connected to the floor 1, and the other end is used to be connected to the front panel of the vehicle. The middle part of the first longitudinal beam 7 has a concave 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 refer to the structure of the first longitudinal beam 7, and will not be repeated here.

[0110] In one example, if Fig.11 As shown, one end of the first longitudinal beam 7 connected to the floor 1 has a third flange structure 71, and the third flange structure 71 is used to connect to the first cross beam body 21 in the first cross beam assembly 2. In this way, the connection stability between the first longitudinal beam 7 and the first cross beam assembly 2 can be improved.

[0111] like Fig.12 As shown, one end of the middle channel connecting plate 9 is connected to the floor 1 , and the other end is used to be connected to the front panel 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 middle channel connecting plate 9 .

[0112] For the components shown in the embodiments of the present disclosure, unless otherwise specified, the connection method between the components can be one or more of spot welding, CO2 welding, riveting, bolts, bonding, and self-piercing riveting processes, and the embodiments of the present disclosure are not limited to this.

In this way, the reinforcement cavity 200 can effectively improve the structural rigidity of the floor assembly. When a collision occurs, the first crossbeam assembly 2, the second crossbeam assembly 3, the first threshold assembly 4 and the second threshold assembly 5 can serve as a force transmission path to improve the force transmission effect. In addition, since the first crossbeam assembly 2 and the second crossbeam assembly 3 are both hollow structures, the overall quality of the floor assembly will not be greatly improved, and therefore the energy consumption of the vehicle will not be excessively increased.
