[0041] Figure 1 FIG. 1 is a schematic diagram of a front floor structure 100 provided according to one embodiment of the present application. Figure 2 for Figure 1 See the exploded view of each seat cross member assembly 20 in FIG. Figure 1 and Figure 2 In some optional embodiments, the front floor structure 100 includes a front floor body 10 and a plurality of seat cross beam assemblies 20 .

[0042] The front floor body 10 is formed with a plurality of ribs 11 spaced apart along the Y direction. Each rib 11 protrudes toward the same side in the Z direction and extends along the X direction.

[0043] Each seat cross beam assembly 20 extends along the Y direction and is connected to a plurality of ribs 11 . The ribs 11 are aligned in the Z direction to facilitate adjustment of the installation position of each seat cross beam assembly 20 on the front floor body 10 in the X direction.

[0044] In this embodiment, the front floor structure 100 comprises at least a front floor body 10 and a plurality of seat cross beam assemblies 20. The front floor body 10 is the main load-bearing component of the front floor structure 100, and other components of the front floor structure 100 are arranged based on the front floor body 10.

[0045] The multiple seat crossbar assemblies 20 are fixedly mounted on one side of the front floor body 10 in the Z direction. Specifically, the front floor body 10 is formed with a plurality of ribs 11, which are spaced apart in the Y direction. Furthermore, each rib 11 protrudes toward the same side in the Z direction and is arranged to extend along the X direction.

[0046] It should be understood that when installing multiple seat cross beam assemblies 20 on the front floor body 10, each seat cross beam assembly 20 should first be connected to the rib 11 protruding in the Z direction in the front floor body 10, and each seat cross beam assembly 20 is extended along the Y direction, thereby forming a cross-type splicing structure with the rib 11 extending in the X direction.

[0047] Furthermore, since the raised heights of the ribs 11 are the same, that is, the ribs 11 are aligned in the Z direction, before the seat crossbeam assembly 20 is fixed, the assembler can easily move the seat crossbeam assembly 20 in the X direction to adjust the installation position of the seat crossbeam assembly 20 on the front floor body 10 in the X direction.

[0048] In the front floor structure 100 provided herein, assemblers can adjust the mounting position of each seat cross member 20 on the front floor body 10 in the X-axis to accommodate the installation requirements of different seats in different vehicle models and meet the interior space requirements of different vehicle models. This enhances the versatility of the front floor structure 100.

[0049] exist Figure 1 and Figure 2 In the illustrated embodiment, there are two seat crossbeam assemblies 20, one for the front seat crossbeam assembly 20a and the other for the rear seat crossbeam assembly 20b. These two assemblies have similar structures and cooperate to securely install the seat. It should be understood that since the assembler can adjust the positions of both the front seat crossbeam assembly 20a and the rear seat crossbeam assembly 20b on the front floor body 10 in the X-direction, i.e., the X-direction distance between the front seat crossbeam assembly 20a and the front floor body 10 is adjustable, as is the distance between the front seat crossbeam assembly 20a and the rear seat crossbeam assembly 20b. Adjusting these distances allows for adapting to the installation of seats of varying sizes and adjusting the vehicle's interior space layout.

[0050] Furthermore, in the illustrated embodiment, the multiple ribs 11 substantially cover the entire front floor panel 10. Specifically, the length of the ribs 11 in the X-direction is slightly less than the X-direction length of the front floor panel 10, and the spacing between the two outermost ribs 11 in the Y-direction is slightly less than the Y-direction width of the front floor panel 10. It should be understood that the X-direction length and Y-direction coverage of the ribs 11 can be adjusted to meet seat installation requirements.

[0051] It should be noted that the front floor structure 100 can be applied to new energy vehicles, which can include electric vehicles, plug-in hybrid vehicles, and extended-range vehicles. Understandably, these vehicles all utilize power batteries. Sharing the power battery assembly (battery pack) with the front floor is a design concept for new energy vehicles, aiming to optimize space, reduce costs, and improve safety.

[0052] In this embodiment, the ribs 11 can enhance the structural strength. Moreover, each rib 11 is convex in the Z direction, and the Z-direction opposite side of the convex side is correspondingly a groove, which is conducive to the flow of electrophoretic liquid.

[0053] Figure 3 This is a schematic diagram of the assembly of the front floor structure 100 and the seat 200 according to one embodiment of the present application. Figure 3 In one optional embodiment, the seat crossbeam assembly 20 includes a crossbeam 21, which is connected to the plurality of ribs 11 and forms a seat mounting interface.

[0054] Figure 4This is a schematic diagram of the assembly of the front floor structure 100 and the seat 200 according to another embodiment of the present application. Figure 4 In another optional embodiment, the seat crossbeam assembly 20 includes a crossbeam 21 and a plurality of seat mounting brackets 22, the crossbeam 21 is connected to a plurality of ribs 11, and the plurality of seat mounting brackets 22 are arranged at intervals along the extension direction of the crossbeam 21 and are located on the same side of the crossbeam 21 in the Z direction, and each seat mounting bracket 22 forms a seat mounting interface.

[0055] In both embodiments, the seat crossbeam assembly 20 includes a crossbeam 21 connected to the plurality of ribs 11 on the front floor body 10. In the first embodiment, a seat mounting interface is formed on the crossbeam 21 for mounting the seat 200.

[0056] In the second embodiment, the seat cross member assembly 20 further includes a plurality of seat mounting brackets 22 . These seat mounting brackets 22 are spaced apart along the extension direction of the cross member 21 , i.e., spaced apart in the Y direction. Furthermore, each of the seat mounting brackets 22 is fixedly mounted on the upper side of the cross member 21 and defines a seat mounting interface for mounting the seat 200 .

[0057] It is understandable that when the solution in the first embodiment is adopted, when the installation height of the seat 200 needs to be adjusted, the height of the beam 21 needs to be redesigned, which takes a long development cycle, resulting in the entire seat beam assembly 20 being heavy, costly, and having poor versatility.

[0058] By comparing the two embodiments, it can be seen that when multiple seat mounting brackets 22 are additionally provided, the installation height of the seat 200 can be adjusted by designing seat mounting brackets 22 of different heights to meet the requirements of different vehicle models for seat installation positions. Moreover, only the height of the designed seat mounting bracket 22 needs to be adjusted, which shortens the development cycle, further improves the versatility of the front floor structure 100, and reduces costs.

[0059] It should be noted that the seat mounting interface here can be connected to the seat matching interface on the seat 200. These interfaces can be a combination of through holes, threaded holes, etc., and the seat 200 can be installed on the seat crossbeam assembly 20 through fastening connectors (such as screws, bolts, pins, etc.).

[0060] Figure 5 for Figure 1 A cross-sectional view of the front floor structure 100 at AA in FIG. Figure 6 for Figure 1 The cross-sectional view of the front floor structure 100 at BB in FIG. Figure 2 、 Figure 5 and Figure 6The cross beam 21 includes an arch plate 211 , a front overlapping lug plate 212 and a rear overlapping lug plate 213 .

[0061] The front lap lug plate 212 and the rear lap lug plate 213 are respectively located on both sides of the bottom of the arch plate 211 in the X direction. The front lap lug plate 212 and the rear lap lug plate 213 are both attached to the multiple ribs 11, and the arch plate 211 and the front floor body 10 cooperate to form a first reinforcement cavity R1 extending along the Y direction.

[0062] In this embodiment, the crossbeam 21 comprises at least an arch plate 211, a front lap lug plate 212 and a rear lap lug plate 213. The front lap lug plate 212 is located on the front side of the arch plate 211, and the rear lap lug plate 213 is located on the rear side of the arch plate 211, i.e., on both sides in the X direction.

[0063] The front and rear lap lugs 212 and 213 are both flat plates, meaning their lower surfaces intersect with the ribs 11. In practice, the crossbeam 21 is joined to the front floor panel 10 by welding the front and rear lap lugs 212 and 213 to the ribs 11. This planar connection facilitates movement to adjust the X-axis position before welding.

[0064] Furthermore, because the front lap lugs 212 and the rear lap lugs 213 are both located at the bottom of the arch plate 211, the arch plate 211 protrudes from the front floor body 10. This, in conjunction with the front floor body 10, forms a first reinforcement cavity R1. Furthermore, because the crossbeam 21 extends along the Y-direction, the first reinforcement cavity R1 also extends along the Y-direction. This first reinforcement cavity R1 improves the structural strength of the front floor structure 100.

[0065] In a further optional embodiment, the arch plate 211 includes a transverse plate section 2111, a front vertical plate section 2112, and a rear vertical plate section 2113. The front vertical plate section 2112 is connected between the transverse plate section 2111 and the front overlapping lug plate 212, and the rear vertical plate section 2113 is connected between the transverse plate section 2111 and the rear overlapping lug plate 213.

[0066] In this embodiment, the crossbeam 21 is a bent plate structure, wherein the arch plate 211 is formed by sequentially connecting a front vertical plate section 2112, a horizontal plate section 2111, and a rear vertical plate section 2113. The front overlapping lugs 212 extend outwardly from the bottom of the front vertical plate section 2112 along the X direction, and the rear overlapping lugs 213 extend outwardly from the bottom of the rear vertical plate section 2113. As a result, the cross section of the entire crossbeam 21 resembles a "X" shape.

[0067] In a further optional embodiment, the seat mounting bracket 22 includes a box body 221 and an X-direction overlapping lug plate 222 and / or a Y-direction overlapping lug plate 223 .

[0068] The X-direction overlap lug 222 is located at the bottom of the X-direction side of the box body 221 and fits the vertical plate section of the arch plate 211. The Y-direction overlap lug 223 is located at the bottom of the Y-direction side of the box body 221 and fits the horizontal plate section 2111. The box body 221 cooperates with the crossbeam 21 to form a second reinforcement cavity R2.

[0069] In this embodiment, the seat mounting bracket 22 includes a box body 221 and at least one of an X-direction overlapping lug plate 222 and a Y-direction overlapping lug plate 223. Specifically, the seat mounting bracket 22 includes the box body 221 and the X-direction overlapping lug plate 222, or includes the box body 221 and the Y-direction overlapping lug plate 223, or includes the box body 221, the X-direction overlapping lug plate 222, and the Y-direction overlapping lug plate.

[0070] The X-direction overlapping lug plate 222 and the Y-direction overlapping lug plate 223 are used to cooperate with the crossbeam 21. The seat mounting bracket 22 has at least one of the X-direction overlapping lug plate 222 and the Y-direction overlapping lug plate 223, so as to be connected to the crossbeam 21.

[0071] In specific applications, the X-direction overlapping ear plate 222 is located at the bottom of the X-direction side of the box body 221. The X-direction overlapping ear plate 222 can be formed at the bottom of one X-direction side of the box body 221, or can be formed at the bottom of both X-direction sides, and the X-direction overlapping ear plate 222 is fitted to the corresponding vertical plate section.

[0072] exist Figure 5 In the illustrated embodiment, X-direction overlapping ear plates 222 are formed at the bottom of both sides of the box body 221 in the X direction. The outer covers of the X-direction overlapping ear plates 222 on both sides are fitted onto the vertical plate sections on both sides of the arch plate 211 in the X direction, which can play a limiting role.

[0073] In specific applications, the Y-direction overlapping ear plate 223 is located at the bottom of the Y-direction side of the box body 221. The Y-direction overlapping ear plate 223 can be formed at the bottom of one Y-direction side of the box body 221, or at the bottom of both Y-direction sides, and the Y-direction overlapping ear plate 223 is attached to the cross-plate section 2111.

[0074] exist Figure 2 In the illustrated embodiment, Y-direction overlapping lugs 223 are formed on both sides of the bottom of the box body 221 in the Y direction, and the Y-direction overlapping lugs 223 on both sides are attached to the horizontal plate section 2111 of the arch plate 211 .

[0075] In a specific application, the X-direction overlapping ear plate 222 and the Y-direction overlapping ear plate 223 are fixed to the arch plate 211 by welding. Accordingly, the box body 221 is above the X-direction overlapping ear plate 222 and the Y-direction overlapping ear plate 223, that is, above the arch plate 211, so that a second reinforcement cavity R2 can be formed to further improve the structural strength of the front floor structure 100.

[0076] In a further optional embodiment, the first reinforcement cavity R1 and the second reinforcement cavity R2 are both configured to be tapered from bottom to top.

[0077] In this embodiment, the first reinforcement cavity R1 and the second reinforcement cavity R2 are parallel in the Z direction, and both the first reinforcement cavity R1 and the second reinforcement cavity R2 adopt a structure that is narrow at the top and wide at the bottom, which can effectively disperse and transmit stress, improve the anti-deformation ability, and increase the stability of the structure.

[0078] See also Figure 1 and Figure 2 In some optional embodiments, the seat crossbeam assembly 20 further includes a left connecting plate 23 and a right connecting plate 24. The left connecting plate 23 and the right connecting plate 24 are respectively disposed at the Y-direction ends of the crossbeam 21, and each seat mounting bracket 22 is located between the left connecting plate 23 and the right connecting plate 24.

[0079] In this embodiment, the seat cross member assembly 20 further includes a left connecting plate 23 and a right connecting plate 24. The left connecting plate 23 and the right connecting plate 24 are located at the left and right ends of the cross member 21, i.e., at the Y-direction ends. Accordingly, each seat mounting bracket 22 is located between the connecting plates on either side. The left and right connecting plates 23 and 24 on either side of the Y-direction are used to connect to other components of the front floor structure 100.

[0080] In a further optional embodiment, the front floor structure 100 further includes a left beam 30 and a right beam 40 , and the left beam 30 and the right beam 40 are respectively located on both sides of the front floor body 10 in the Y direction.

[0081] The left connecting plate 23 is connected between the left beam 30 and the cross beam 21 and is partially attached to the front floor body 10. The right connecting plate 24 is connected between the right beam 40 and the cross beam 21 and is partially attached to the front floor body 10.

[0082] In this embodiment, the front floor structure 100 further includes a left beam 30 and a right beam 40 located on the left and right sides of the front floor body 10. The Y-direction ends of the crossbeam 21 are overlapped with the left beam 30 and the right beam 40, respectively, via a left connecting plate 23 and a right connecting plate 24. Furthermore, the left connecting plate 23 and the right connecting plate 24 are also overlapped and fixed to the front floor body 10. Specifically, the connecting plates can be welded to the corresponding side beams and the front floor body 10.

[0083] It should be understood that the Y-direction outer ends of the left connecting plate 23 and the Y-direction outer ends of the right connecting plate 24 are both formed with a certain shape of overlap interface to adapt to the overlap of the side beam. However, the shape of the overlap interface is not convenient for processing. The left and right ends of the cross beam 21 are separated in the form of the left connecting plate 23 and the right connecting plate 24 to facilitate the processing and manufacturing of the cross beam 21. Specifically, the cross beam 21 is set to be made in one piece.

[0084] In a specific application, the cross beam 21 can be made by a rolling process to replace the commonly used stamping process. The left connecting plate 23 and the right connecting plate 24 have the same structure and are both special-shaped sheet metal parts.

[0085] Another aspect of the present application provides a vehicle, which includes a seat 200 and the front floor structure 100 . The seat 200 is connected to the crossbeam 21 in the seat crossbeam assembly 20 ; or the seat 200 is connected to the seat mounting bracket 22 in the seat crossbeam assembly 20 .

[0086] See also Figure 3 and Figure 4 , Figure 3 The assembly scheme of the seat 200 used in the basic model is presented. Figure 4 The assembly scheme for a seat 200, adapted from a base vehicle model, is presented. As can be seen from the above, the Z-axis mounting position of the seat 200 can be adjusted by adding or removing seat mounting brackets 22 at different heights, and the X-axis position of the seat 200 can be adjusted by moving the seat cross member assembly 20 relative to the front floor body 10 in the X-axis. Clearly, the low-cost and rapid development advantages of the front floor structure 100 shorten the vehicle development cycle. Of course, the vehicle also offers other advantages brought about by the front floor structure 100, which will not be elaborated on here.

[0087] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
