[0063] 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.

[0064] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0065] The disclosed embodiment provides a floor assembly, Figure 1 This is a schematic diagram of the overall structure of the floor assembly from one perspective. Figure 2 This is a schematic diagram of the overall structure of the floor assembly from another perspective, combined with Figure 1 , Figure 2 As shown, the floor assembly includes a central channel structure 1, a floor body 2, a crossbeam assembly 3 and a longitudinal beam assembly 4. The floor body 2 is fixedly connected to one side of the central channel structure 1. The crossbeam assembly 3 includes a first crossbeam 31 and a second crossbeam 32 which are parallel to each other. The first crossbeam 31 is fixedly connected to the upper surface of the floor body 2 and the central channel structure 1 respectively.

[0066] in, Figure 3 is a cross-sectional view of the floor assembly at the first cross beam 31, Figure 4 FIG. 2 is a cross-sectional view of the floor assembly at the second cross member 32. Figure 3 , Figure 4 As shown, a first cavity A is formed between the lower surface of the first crossbeam 31 and the floor body 2, and the second crossbeam 32 is fixedly connected to the upper surface of the floor body 2 and the middle channel structure 1, respectively, and a second cavity B is formed between the lower surface of the second crossbeam 32 and the floor body 2. Figures 2 to 4 As shown, the longitudinal beam assembly 4 includes a first longitudinal beam 41 and a second longitudinal beam 42. The first longitudinal beam 41 is fixedly connected to the lower surface of the floor body 2, and a third cavity C is formed between the upper surface of the first longitudinal beam 41 and the floor body 2. The second longitudinal beam 42 is located on the side of the first longitudinal beam 41 close to the middle channel structure 1, and is fixedly connected to the floor body 2 and the middle channel structure 1 respectively, and a fourth cavity D is formed between the upper surface of the second longitudinal beam 42 and the floor body 2 and the middle channel structure 1.

[0067] In the disclosed embodiment, the first cavity A and the second cavity B can be formed on the upper surface of the floor body 2 through the cross beam assembly 3, so that the impact force of the vehicle body in the extension direction of the cross beam assembly 3 can be absorbed through the cavities. At the same time, the third cavity C and the fourth cavity D can be formed on the lower surface of the floor body 2 through the longitudinal beam assembly 4, so that the impact force of the vehicle body in the extension direction of the longitudinal beam assembly 4 can be absorbed through the cavities. Therefore, collisions can be buffered in different directions through multiple cavities, so that the anti-intrusion deformation capability of the vehicle body can be greatly improved, and thus the collision safety performance of the vehicle can be greatly improved.

[0068] like Figure 1As shown, the first cross beam 31 and the second cross beam 32 are respectively fixedly connected to different parts of the floor body 2, so that the lateral impact on the vehicle can be buffered at different parts, thereby further improving the collision safety performance of the vehicle in the lateral direction.

[0069] Similarly, if Figure 2 As shown, the first longitudinal beam 41 and the second longitudinal beam 42 are respectively fixedly connected to different parts of the floor body 2, so that the longitudinal impact on the vehicle can be buffered at different parts, thereby further improving the collision safety performance of the vehicle in the longitudinal direction.

[0070] Combination Figure 1 , Figure 2 As shown, it can be seen that the floor assembly is a symmetrical structure. The floor assembly includes two floor bodies 2, which are respectively located on both sides of the central channel structure 1 and are mirror-symmetrical, and are respectively fixedly connected to the central channel structure 1. Correspondingly, the crossbeam assembly 3 includes two mirror-symmetrical first crossbeams 31 and two mirror-symmetrical second crossbeams 32, and the longitudinal beam assembly 4 includes two mirror-symmetrical first longitudinal beams 41 and two mirror-symmetrical second longitudinal beams 42. In this way, the two first crossbeams 31 can buffer the lateral impact force of the vehicle on both sides of the central channel structure 1, and the two first longitudinal beams 41 can buffer the longitudinal impact force of the vehicle on both sides of the central channel structure 1, thereby greatly improving the anti-collision capability of the vehicle.

[0071] In some embodiments, Figure 1 As shown, the floor assembly also includes a bracket assembly 5. The bracket assembly 5 includes a first bracket 51, which is located at one end of the first crossbeam 31 close to the middle channel structure 1 and is fixedly connected to the first crossbeam 31, the floor body 2 and the middle channel structure 1, respectively. Figure 3 As shown, a fifth cavity E is formed between the lower surface of the first bracket 51 and the first cross beam 31 .

[0072] In this way, through the first bracket 51, a fifth cavity E can be formed above the first cross beam 31, and the fifth cavity E and the first cavity A are adjacent to each other in the up and down directions, thereby improving the deformation resistance of the first cross beam 31 at one end close to the middle channel structure 1 in the up and down directions, so as to further improve the anti-collision ability of the vehicle.

[0073] In some embodiments, Figure 1 As shown, the longitudinal beam assembly 4 also includes a threshold longitudinal beam 43, and the threshold longitudinal beam 43 is fixedly connected to the floor body 2. The bracket assembly 5 also includes a second bracket 52, which is located at an end of the first cross beam 31 away from the central channel structure 1 and is respectively connected to the first cross beam 31, the floor body 2 and the threshold longitudinal beam 43. Figure 3As shown, a sixth cavity F is formed between the lower surface of the second bracket 52 and the first cross beam 31 .

[0074] In this way, through the second bracket 52, a sixth cavity F can be formed above the first cross beam 31, and the sixth cavity F and the second cavity B are adjacent to each other in the up and down directions, thereby improving the deformation resistance of the first cross beam 31 at one end close to the middle channel structure 1 in the up and down directions, so as to further improve the anti-collision ability of the vehicle.

[0075] Optionally, the first bracket 51 and the second bracket 52 are used to install seats, respectively. The seats on the vehicle are set on the floor structure, so the floor structure needs to bear a large load at the installation position of the vehicle seat. The first bracket 51 and the second bracket 52 support the seat, which can prevent the floor structure from being deformed at the installation position of the seat, thereby further improving the structural strength of the vehicle.

[0076] Corresponding to the two first cross beams 31 , the bracket assembly 5 includes two first brackets 51 and two second brackets 52 , and the specific connection relationship will not be described in detail here.

[0077] In some embodiments, in combination Figure 1 , Figure 3 As shown, the middle channel structure 1 includes a main body 11 and a first reinforcement plate 12. The main body 11 is a frame structure with an open bottom. The first reinforcement plate 12 is located on the upper part of the main body 11 and is fixedly connected to the main body 11. The lower surface is spaced apart from the main body 11 to form a seventh cavity G.

[0078] In this way, the seventh cavity G is formed on the top of the main body 11 by the first reinforcing plate 12, thereby improving the anti-deformation capability of the main body 11 in the up-down direction, and also improving the anti-deformation capability of the central channel structure 1 in the extension direction. Therefore, the present disclosure can further improve the anti-collision capability of the vehicle through the cooperation of the main body 11 and the first reinforcing plate 12.

[0079] like Figure 3 As shown, the main body 11 has a hollow channel inside. In this way, the torsional rigidity and bending rigidity of the vehicle body can be enhanced to improve the overall rigidity,

[0080] In some embodiments, Figure 2 As shown, the middle channel structure 1 also includes a second reinforcing plate 13, combined with Figure 3 As shown, the second reinforcing plate 13 is located in the main body 11 and is fixedly connected to two inner side walls of the main body 11 , and an eighth cavity H is formed between the upper surface and the main body 11 .

[0081] In this way, the side wall of the main body 11 in the frame structure can be supported by the second reinforcing plate 13 to improve the structural strength and overall rigidity of the main body 11. In addition, an eighth cavity H is formed between the upper surface of the second reinforcing plate 13 and the main body 11, which can further improve the deformation resistance of the main body 11, thereby improving the overall deformation resistance of the middle channel structure 1, and improving the anti-collision performance of the middle channel structure 1.

[0082] In some embodiments, Figure 1 As shown, the central channel structure 1 also includes a connecting plate 14, which is fixedly connected to the main body 11 and the first reinforcing plate 12 respectively, and protrudes from the side of the floor body 2. The connecting plate 14 is tilted relative to the first reinforcing plate 12 to be connected to the vehicle body, and an open groove 141 is provided in the connecting plate 14 to form a reinforcement groove with the vehicle body.

[0083] In this way, the main body 11 can be connected to the vehicle body through the connecting plate 14. Compared with the integrally formed structure, on the one hand, the production and sales rate can be improved and the waste generated can be reduced. On the other hand, the split design can prevent the central channel structure 1 from being too long and easily deformed during the production process, thereby improving the yield rate of the central channel structure 1. In addition, since the connecting plate 14 has an open groove 141 and can form a ninth cavity with the vehicle body, the anti-deformation ability of the central channel structure 1 can be improved.

[0084] In some embodiments, Figure 1 As shown, the central channel structure 1 further includes a third reinforcing plate 15 . Figure 5 is a cross-sectional view of the middle channel structure 1 at the connecting plate 14 and the third reinforcing plate 15, taken along the extending direction of the middle channel structure 1, combined with Figure 5 As shown, the third reinforcing plate 15 is located on the upper portion of the connecting plate 14 and is fixedly connected to the connecting plate 14 , and the lower surface thereof forms a tenth cavity J with the connecting plate 14 .

[0085] In this way, by forming the tenth cavity J through the third reinforcing plate 15 and the connecting plate 14, the structural strength of the central channel structure 1 at the connecting plate 14 can be strengthened to improve the anti-deformation ability of the central channel structure 1 at the connecting plate 14, so that when the vehicle body is hit, the external impact force can be buffered, thereby improving the anti-collision performance of the vehicle.

[0086] In some embodiments, Figure 1 As shown, the longitudinal beam assembly 4 further includes a cover plate 44 , a portion of which is connected to the upper surface of the floor body 2 , and another portion of which is tilted relative to the floor body 2 , and the tilted portion of the cover plate 44 is used to be connected to the vehicle body.

[0087] In this way, the cover plate 44 can improve the connection strength between the floor assembly and the vehicle body, thereby improving the overall structural strength of the vehicle.

[0088] Alternatively, if Figure 1 As shown, a portion of the cover plate 44 is fixedly connected to the second cross member 32 .

[0089] In some embodiments, Figure 1 As shown, the floor body 2 has a plurality of protrusions 21 and a plurality of grooves 22 .

[0090] In this way, the structural rigidity of the floor body 2 can be improved, thereby improving the overall rigidity of the vehicle, and further improving the anti-collision performance of the vehicle, thereby improving the safety performance of the vehicle.

[0091] The floor assembly provided by the embodiment of the present disclosure will be further described below with reference to some drawings.

[0092] Figure 6 is a schematic diagram of the structure of the floor body 2, such as Figure 6 As shown, the floor body 2 includes a plurality of protrusions 21 and grooves 22 to enhance the anti-deformation capability of the floor. The floor body 2 has a first protrusion 2a and a second protrusion 2b. The first protrusion 2a is located at the bottom of the first crossbeam 31 and is adapted to the first crossbeam 31. The second protrusion 2b is located at the bottom of the second crossbeam 32 and is adapted to the second crossbeam 32. In this way, the first crossbeam 31 and the second crossbeam 32 can be positioned by the first protrusion 2a and the second protrusion 2b, thereby greatly reducing the difficulty of assembling the first crossbeam 31 and the second crossbeam 32. The edge of the floor body 2 also has a snap-in notch 2c for positioning the central channel structure 1 and the second longitudinal beam 42.

[0093] The floor body 2 is a thin plate planar structure, and the material is metal or polymer material, such as cold-rolled thin steel plate. The thickness of the material can be 0.5mm-2mm, which is determined according to the strength of the material.

The side of the first main body portion 11 has a first clamping groove 11c, which is used to clamp the end of the first crossbeam 31, and the side of the third main body portion 11 has a second clamping groove 11d, which is clamped to the end of the second crossbeam 32. The way of connection through the clamping groove can more conveniently realize the installation and positioning of the first crossbeam 31 and the second crossbeam 32, thereby improving the convenience of assembly of the floor assembly.

[0096] The edges of the first main body portion 111, the second main body portion 112, the third main body portion 113 and the fourth main body portion 114 extend outward to form a first connecting portion 11a, which is connected to the first cross beam 31, the second cross beam 32 and the floor body 2. The first connecting portion 11a has a plurality of concave and convex structures, which, on the one hand, position the first cross beam 31, the second cross beam 32 and the floor body 2 and the main body, and, on the other hand, can improve the anti-deformation ability of the first connecting portion 11a.

[0097] Optionally, the first connection portion 11a can be connected to the first cross beam 31, the second cross beam 32 and the floor body 2 by means of, for example but not limited to, spot welding, CO2 welding, riveting, bolting, bonding or SPR (Self-Piercing Riveting).

[0098] The top of the fourth main body portion 114 has a second connecting portion 11 b , and the second connecting portion 11 b has a plurality of strip-shaped grooves, which are respectively used to position and connect the first reinforcing plate 12 to improve the convenience of assembling the floor assembly.

[0100] The middle channel structure 1 is a thin plate planar structure, and the material is metal or polymer material, such as cold-rolled thin steel plate. The thickness of the material can be 0.5mm-2mm, which is determined according to the strength of the material.

In this way, the deformation resistance of the central channel structure 1 can be improved, thereby improving the safety performance of the vehicle.

The thickness of the material can be 0.5mm-2mm, which is determined according to the strength of the material.

The first inner plate 131 and the second inner plate 132 can be connected to the main body 11 by methods such as but not limited to spot welding, CO2 welding, riveting, bolting, bonding or SPR.

[0104] The side walls of the first inner plate 131 and the second inner plate 132 are used to be fixedly connected to the main body 11 to form the eighth cavity H, so as to enhance the structural strength of the central channel structure 1, improve the anti-deformation capability of the central channel structure 1, and thus improve the safety performance of the vehicle. In addition, the first inner plate 131 and the second inner plate 132 respectively reinforce the main body 11 at different positions, which can further ensure that the main body 11 has a high structural strength at all positions.
