Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0050] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.

[0051] Embodiments

[0052] Figure 1 is a top view of the vehicle 1000 in an embodiment of the present application.

[0053] Referring to Figure 1This embodiment provides a vehicle 1000. The vehicle 1000 has a monocoque body, meaning it does not have a separate frame. The body includes a floor structure 100, which includes a floor 10 and crossbeams, longitudinal beams, and other structures disposed on the floor 10. In the event of a collision, the crossbeams, longitudinal beams, and other structures can absorb and dissipate collision energy through deformation. The body also includes components such as a front bulkhead, side bulkheads, and a roof. The floor structure 100 and these components are interconnected to form the overall structure of the monocoque body.

[0054] Thus, since the monocoque body does not have an independent frame, the weight of the vehicle 1000 is reduced, which helps to improve the fuel economy and power performance of the vehicle 1000, and saves manufacturing costs. In addition, the monocoque body structure is compact and saves space.

[0055] like Figure 1 As shown, the floor structure 100 in this embodiment can be a front floor structure. The front floor structure is located at the front of the vehicle 1000, including the area below the driver and front passenger footwells. In the event of a frontal collision, the front floor structure can transfer and disperse the impact force to other parts of the vehicle body. It should be noted that... Figure 1 This is only used to illustrate the location of floor structure 100 and does not represent the actual structure of floor structure 100.

[0056] Figure 2 for Figure 1 A top view of the floor structure 100 in the illustrated embodiment; Figure 3 for Figure 1 A bottom view of the floor structure 100 in the illustrated embodiment; Figure 4 for Figure 1 A schematic cross-sectional view of the floor structure 100 in the illustrated embodiment.

[0057] See Figure 2 to Figure 4 The floor structure 100 provided in this embodiment includes a floor 10, a first beam assembly 20, and a second beam assembly 30. The first beam assembly 20 is disposed on one side of the floor 10 and includes a plurality of first crossbeams 21. The plurality of first crossbeams 21 are spaced apart from each other along the length direction X of the vehicle 1000, and extend from one end of the floor 10 along the width direction Y of the vehicle 1000 to the other end of the floor 10. The second beam assembly 30 is disposed on the other side of the floor 10 and includes a plurality of longitudinal beams 31. The plurality of longitudinal beams 31 are spaced apart from each other along the width direction Y of the vehicle 1000, and extend from one end of the floor 10 along the length direction X of the vehicle 1000 to the other end of the floor 10.

[0058] The floor structure 100, due to the first beam assembly 20 and the second beam assembly 30 being arranged at different sides of the floor 10 respectively, enhances the structural strength and bending resistance of the floor structure 100, and makes the arrangement spaces of the first beam assembly 20 and the second beam assembly 30 not affect each other, so that the first cross beam 21 and the longitudinal beam 31 can respectively extend through the floor 10 along different directions. By arranging the first cross beam 21 to extend from one end of the floor 10 along the width direction Y of the vehicle 1000 to the other end of the floor 10, the lateral force transmission capability is improved, that is, in the event of a side collision, the collision force can be transmitted from one end of the floor 10 to the other end through the first cross beam 21, so that the collision force can be more effectively transmitted and dispersed, thereby enhancing the resistance to side collision. By arranging the longitudinal beam 31 to extend from one end of the floor 10 along the length direction X of the vehicle 1000 to the other end of the floor 10, the forward force transmission capability is improved, that is, in the event of a front collision, the collision force can be transmitted from one end of the floor 10 to the other end through the longitudinal beam 31, so that the collision force can be more effectively transmitted and dispersed, thereby enhancing the resistance to front collision. Therefore, the floor structure 100 improves the safety of the vehicle 1000 in the event of side collision and front collision, so as to be suitable for more complex working conditions, such as more serious collision, or off-road conditions, etc.

[0059] Optionally, the first beam assembly 20 and the second beam assembly 30 are connected with the floor 10 by welding (such as aluminum spot welding), riveting, screwing, and gluing, etc. SPR (Self -Piercing Rivet) and FDS (Flow Drill Screw) can also be used to connect the floor 10.

[0060] In some embodiments, as shown in Figure 4 The floor 10 has a top side 11 and a bottom side 12 opposite along the height direction Z of the vehicle 1000, and the first beam assembly 20 is arranged on the top side 11 and the second beam assembly 30 is arranged on the bottom side 12. Figure 2 Figure 3 In some embodiments, as shown in

[0061] In some embodiments, as shown in Figure 2 The floor structure 100 further comprises a central passage 40 connected to the top side 11 (see Figure 4 ​), one end of the central channel 40 is connected to the front cross beam 2101 away from the rear cross beam 2102, and the other end of the central channel 40 extends along the length direction X of the vehicle 1000 towards the front. In this way, the force can be transmitted and dispersed between the central channel 40 and the front cross beam 2101, thereby reducing the stress intensity of each part when the vehicle 1000 is subjected to external force, and improving the reliability of the floor structure 100. Functional components such as handrails and storage boxes can be provided above the central channel 40. In this embodiment, the rear cross beam 2102 has one.

[0062] Optionally, the end of the central channel 40 connected to the front cross beam 2101 extends to the side of the front cross beam 2101 away from the floor 10 and overlaps with the front cross beam 2101, that is, the central channel 40 and the front cross beam 2101 partially overlap and are connected, so that the force can be more effectively transmitted and distributed between the central channel 40 and the front cross beam 2101, to improve the strength and stability of the connection.

[0063] In some embodiments, the central channel 40 is connected to the floor 10 and the front cross beam 2101 by welding (such as aluminum spot welding), riveting, screwing, and gluing, etc. SPR (Self -Piercing Rivet, self-piercing riveting) and FDS (Flow Drill Screw, flow drill screw) connection can also be used.

[0064] In some embodiments, as shown in Figure 2 The floor structure 100 further includes a plurality of seat supports 50. The plurality of seat supports 50 correspond to the plurality of first cross beams 21 respectively, and the seat supports 50 are arranged on the side of the corresponding first cross beams 21 away from the floor 10 along the height direction Z of the vehicle 1000, and the plurality of seat supports 50 corresponding to the same first cross beam 21 are arranged spaced apart from each other along the width direction Y of the vehicle 1000. In this way, the seat supports 50 are arranged for mounting the seats of the vehicle 1000, and since a plurality of seat supports 50 are arranged on the same first cross beam 21, the force borne by the seats is more evenly distributed to the first cross beam 21. In this embodiment, there are 8 seat supports 50, and 4 seat supports 50 are arranged on each first cross beam 21.

[0065] In some embodiments, as shown in Figure 3As shown, the second beam assembly 30 further comprises a plurality of second cross beams 32. The plurality of second cross beams 32 are arranged at intervals along the length direction X of the vehicle 1000, and the second cross beams 32 extend along the width direction Y of the vehicle 1000, and at least one end of the second cross beams 32 is connected to the longitudinal beam 31, so as to further improve the overall rigidity of the floor structure 100, and enable force to be transmitted and dispersed between the second cross beams 32 and the longitudinal beam 31, thereby reducing the stress intensity locally borne. Optionally, the end of the second cross beam 32 connected to the longitudinal beam 31 extends to the side of the longitudinal beam 31 away from the floor 10, and overlaps the longitudinal beam 31, so that force is more effectively transmitted and dispersed.

[0066] In some embodiments, in combination with Figure 2 to Figure 4 As shown, the plurality of second cross beams 32 correspond to the plurality of first cross beams 21 respectively, and the second cross beams 32 and the corresponding first cross beams 21 are arranged opposite to each other along the height direction Z of the vehicle 1000, so as to increase the cross-sectional area of the floor structure 100 at the positions of the first cross beams 21 and the second cross beams 32, thereby further improving the structural strength and the bending and torsional rigidity of the floor structure 100. In the present embodiment, there are two second cross beams 32 and two first cross beams 21 respectively.

[0067] In some embodiments, as Figure 3 As shown, the longitudinal beam 31 has two, which are a left longitudinal beam 3101 and a right longitudinal beam 3102 respectively, and the second cross beam 32 is connected between the left longitudinal beam 3101 and the right longitudinal beam 3102, so that force can be transmitted between the left longitudinal beam 3101 and the right longitudinal beam 3102 through the second cross beam 32, thereby further improving the lateral force transmission capability of the floor structure 100.

[0068] In some embodiments, as Figure 3 As shown, the second beam assembly 30 further comprises a plurality of left reinforcing beams 33 and a plurality of right reinforcing beams 34, and the plurality of left reinforcing beams 33 and the plurality of right reinforcing beams 34 correspond to the plurality of second cross beams 32 respectively. One end of the left reinforcing beam 33 is connected to the side of the left longitudinal beam 3101 away from the right longitudinal beam 3102, the left reinforcing beam 33 extends along the width direction Y of the vehicle 1000, and is arranged opposite to the corresponding second cross beam 32. One end of the right reinforcing beam 34 is connected to the side of the right longitudinal beam 3102 away from the left longitudinal beam 3101, the right reinforcing beam 34 extends along the width direction Y of the vehicle 1000, and is arranged opposite to the corresponding second cross beam 32. In this way, by arranging the left reinforcing beam 33 and the right reinforcing beam 34, force can be transmitted between the left reinforcing beam 33, the second cross beam 32 and the right reinforcing beam 34, thereby making the lateral force transmission path more complete.

[0069] Optionally, the end of the left reinforcing beam 33 and the right reinforcing beam 34 connected to the longitudinal beam 31 respectively extends to the side of the longitudinal beam 31 away from the floor 10, and overlaps the longitudinal beam 31, so that force is more effectively transmitted and dispersed.

[0070] Figure 5 for Figure 1 A schematic diagram of the cross-section of the threshold beam 60 in the illustrated embodiment.

[0071] In some embodiments, such as Figure 2 As shown, the floor structure 100 also includes two sill beams 60, which are respectively connected to the two opposite sides of the floor 10 along the width direction Y of the vehicle 1000. A first crossbeam 21 connects the two sill beams 60. Figure 4 and Figure 5 As shown, the sill beam 60 defines multiple cavities 60a, which are staggered in a plane perpendicular to the length direction X of the vehicle 1000 and extend along the length direction X of the vehicle 1000. Thus, the first crossbeam 21 connects the two sill beams 60, making the floor structure 100 a more stable overall structure, enhancing the stiffness of the floor structure 100 in the width direction Y of the vehicle 1000, and enabling force to be transmitted between the two sill beams 60 through the first crossbeam 21, further improving the lateral force transmission capacity of the floor structure 100. Furthermore, because the sill beam 60 defines multiple cavities 60a, in the event of a side collision, each cavity 60a can deform and crush independently, thereby gradually absorbing and dissipating the collision energy, effectively reducing the impact on the occupants and key components of the vehicle 1000, and achieving structural lightweighting while ensuring the strength and stiffness of the sill beam 60. Optionally, the sill beam 60 is formed by an extrusion process.

[0072] In some embodiments, such as Figure 3 As shown, the end of the left reinforcing beam 33 away from the left longitudinal beam 3101 is connected to one of the sill beams 60, and the end of the right reinforcing beam 34 away from the right longitudinal beam 3102 is connected to another sill beam 60, so as to make the lateral force transmission path more complete and further improve the ability to resist side collisions.

[0073] In some embodiments, the end of the sill beam 60 away from the front of the vehicle extends out of the floor 10 and connects to the rear body (not shown). The end of the floor 10 away from the front of the vehicle 1000 along the length direction X of the vehicle 1000 is connected to the rear body. This improves the overall strength and rigidity of the vehicle body.

Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
