In addition, the left end and the left threshold roof beam of seat crossbeam 2 are connected, the right-hand member and the right threshold roof beam of seat crossbeam 2 are connected, can support better between left threshold roof beam and right threshold roof beam, thereby can prevent left threshold roof beam to produce deformation towards the right side better, and can prevent right threshold roof beam to produce deformation towards the left side better, and, make between left threshold roof beam and the right threshold roof beam can form the transmission route of power through seat crossbeam 2, for example, when the vehicle left side is suffered the striking, can transmit and disperse the impact force that left threshold roof beam bore better through seat crossbeam 2, thereby can avoid the stress concentration on the left threshold roof beam better, and then can reduce the influence of striking to land 100 in front better, with the structural strength who guarantees the vehicle.
In a specific example, the vehicle includes a battery pack (not shown), the battery pack is located between the left threshold beam and the right threshold beam in the left-right direction, and the battery pack is located between the front wall and the rear floor of the vehicle body in the front-rear direction, so that the structural strength of the vehicle body can be better enhanced through the center tunnel beam 1 and the seat cross beam 2, and further, the intrusion amount of the vehicle body collision to the installation space of the battery pack can be reduced, so as to ensure the safety of the battery pack, and the safety performance of the vehicle can be improved.
In addition, the center tunnel beam 1 and the seat cross beam 2 are integrally formed, so that the center tunnel beam 1 and the seat cross beam 2 can form a force transmission path, that is, the force acting on the center tunnel beam 1 can be transmitted and dispersed through the seat cross beam 2, and the impact force acting on the seat cross beam 2 can be transmitted and dispersed through the center tunnel beam 1, which is beneficial to further improving the unloading effect of the front floor structure 100 on the impact force.

That is to say, the first cavity 10 extends along the extending direction of the center tunnel beam 1, so that the first cavity 10 can better enhance the anti-deformation capability of the center tunnel beam 1 in the front-rear direction, that is, the center tunnel beam 1 is not easily deformed when bearing the impact force in the front-rear direction, the structural strength is high, and the stability of the front floor structure 100 is favorably improved. In addition, when the structural strength of the center tunnel beam 1 is ensured, the cost input of the center tunnel beam 1 can be better saved, and the weight reduction of the center tunnel beam 1 is facilitated so as to improve the light weight level of the vehicle.
In a specific example, the vehicle further comprises a pipeline assembly, wherein the pipeline assembly may include an electric control wiring harness or a cooling water pipe of the vehicle, and the like, and the pipeline assembly is adapted to extend a wiring or a pipe along the first cavity 10, so that the center channel beam 1 has a good protection effect on the pipeline assembly, so as to improve the stability and reliability of the pipeline assembly, and the space for wiring and piping of the pipeline assembly can be better saved, so that the vehicle is compact in structure and reasonable in layout.
Further, the seat beam 2 forms a second cavity (not shown) with a downward opening, the second cavity extends along the left-right direction, that is, the extending direction of the second cavity is consistent with the extending direction of the seat beam 2, and the deformation resistance of the seat beam 2 in the left-right direction can be better enhanced through the second cavity, that is, the seat beam 2 is not easily deformed when bearing the impact force in the left-right direction, the structural strength is high, and the stability of the front floor structure 100 is favorably improved. In addition, when the structural strength of the seat cross beam 2 is ensured, the cost investment of the seat cross beam 2 can be better saved, and the reduction of the weight of the seat cross beam 2 is facilitated to improve the light weight level of the vehicle.
Wherein, as shown in fig. 2, the first cavity 10 and the second cavity are provided with the first reinforcing structure 3. From this, through setting up first additional strengthening 3 at first die cavity 10 and second die cavity for first additional strengthening 3 can support better on the lateral wall of first die cavity 10 and second die cavity, thereby makes first additional strengthening 3 in the first die cavity 10 can prevent well that well passageway roof beam 1 from collapsing in towards first die cavity 10, and first additional strengthening 3 in the second die cavity can prevent well that seat crossbeam 2 from collapsing in towards the second die cavity. Thus, the deformation resistance of the center tunnel beam 1 and the seat cross beam 2 can be improved well by the first reinforcement structure 3 to improve the structural strength of the front floor structure 100 as a whole.
Further, as shown in fig. 2, 6 and 8, the first reinforcing structure 3 includes a first reinforcing bead 31 extending in a broken line and a second reinforcing bead 32 extending in a straight line, and the first reinforcing bead 31 intersects the second reinforcing bead 32. Specifically, the first reinforcing rib 31 located in the first cavity 10 extends in a zigzag shape along the front-rear direction, a part of the second reinforcing ribs 32 located in the first cavity 10 extends in the left-right direction, the rest part of the second reinforcing ribs 32 located in the first cavity 10 extends in the front-rear direction, and the second reinforcing ribs 32 extending in the front-rear direction, the second reinforcing ribs 32 extending in the left-right direction and the first reinforcing ribs 31 have a plurality of intersecting connection positions, so that the reinforcing effect of the first reinforcing rib 31 and the second reinforcing rib 32 on the structural strength of the channel beam 1 can be improved well; the first reinforcing rib 31 that is located the second die cavity is the broken line form along the left and right directions and extends, the part second reinforcing rib 32 that is located the second die cavity extends along the left and right directions, the rest second reinforcing rib 32 that is located the second die cavity extends along the fore-and-aft direction, the second reinforcing rib 32 that extends along the left and right directions has a plurality of crossing hookup locations with first reinforcing rib 31, thereby can promote the reinforcing effect of first reinforcing rib 31 and second reinforcing rib 32 to the structural strength of seat crossbeam 2 better. Therefore, the first reinforcing rib 31 and the second reinforcing rib 32 can be supported in the first cavity 10 and the second cavity from a plurality of different directions, so that the deformation resistance of the middle channel beam 1 and the seat cross beam 2 in a plurality of directions can be better improved, and the structural strength of the front floor structure 100 can be further improved.
Further, as shown in fig. 3, fig. 7 and fig. 9, the front floor structure 100 further includes a second reinforcing structure 4, and the second reinforcing structure 4 includes a plurality of third reinforcing ribs 41 distributed in a grid shape. Therefore, the density and the coverage area of the second reinforcing structures 4 can be better improved, and the reinforcing effect of the second reinforcing structures 4 is favorably improved. For example, as shown in fig. 3, in which a part of the third reinforcing ribs 41 extends in the front-rear direction, the remaining part of the third reinforcing ribs 41 extends in the left-right direction, and the third reinforcing ribs 41 extending in the front-rear direction intersect with the third reinforcing ribs 41 extending in the left-right direction, the connection positions between the plurality of third reinforcing ribs 41 can be increased well, so as to enhance the reinforcing effect of the second reinforcing structure 4.
Wherein the density of the first reinforcing structures 3 is less than the density of the second reinforcing structures 4, and the height of the first reinforcing structures 3 is greater than the height of the second reinforcing structures 4. That is, the arrangement density of the first and second reinforcing ribs 31 and 32 is less than that of the third reinforcing ribs, and the length of the first and second reinforcing ribs 31 and 32 in the up-down direction is greater than that of the third reinforcing rib 41 in the up-down direction. For example, in the first cavity 10, the upper ends of the first rib 31, the second rib 32, and the third rib 41 are all provided on the ceiling wall of the first cavity 10, and the lower ends of the first rib 31 and the second rib 32 are all lower than the lower end of the third rib 41. From this, through the third strengthening rib 41 that sets up high density, can be when guaranteeing second additional strengthening 4's reinforcing effect for second additional strengthening 4 can make full use of the ascending installation space of horizontal direction, does benefit to the space that reduces second additional strengthening 4 and occupy in the up-and-down direction, and is rationally distributed.
Wherein at least the first cavity 10 is provided with a second reinforcing structure 4. For example, the second reinforcing structure 4 may be provided only in the first cavity 10, that is, both the first reinforcing structure 3 and the second reinforcing structure 4 are provided in the center tunnel beam 1, it can be understood that the center tunnel beam 1 serves as a main connecting member between the front wall and the rear floor of the vehicle body, and the structural strength of the center tunnel beam 1 directly affects the collision strength of the vehicle as a whole. Therefore, through being provided with first additional strengthening 3 and second additional strengthening 4 simultaneously in well passageway roof beam 1, do benefit to the anti deformability that further promotes well passageway roof beam 1, and then can guarantee the overall structure intensity of vehicle. In addition, a second reinforcing structure 4 may be disposed in both the first cavity 10 and the second cavity to further improve the deformation resistance of the center channel beam 1 and the seat cross beam 2, so that the strength of the front floor structure 100 may be improved, which is not particularly limited herein. Secondly, through set up second additional strengthening 4 in first die cavity 10 and second die cavity, when guaranteeing well passageway roof beam 1 and seat crossbeam 2 structural strength, can avoid increasing the thickness of passageway roof beam 1 and seat crossbeam 2 better to can reduce the weight and the cost input of passageway roof beam 1 and seat crossbeam 2 in.

In other words, on the basis that the first reinforcing structures 3 are arranged in the first cavity 10, the first sub-cavity 210 and the second sub-cavity 220, the second reinforcing structures 4 can be flexibly added according to weak stress links of the middle channel beam 1, the front seat cross beam 21 and the rear seat cross beam 22, so as to ensure the structural strength of the middle channel beam 1, the front seat cross beam 21 and the rear seat cross beam 22.

Further, the front seat cross member 21 forms a first sub-cavity 210 that opens downward and extends in the left-right direction, and the rear seat cross member 22 forms a second sub-cavity 220 that opens downward and extends in the left-right direction. From this, can strengthen the anti deformability of front seat crossbeam 21 on the left and right sides orientation better through first sub-cavity 210, second sub-cavity 220 can strengthen the anti deformability of back seat crossbeam 22 on the left and right sides orientation better for front seat crossbeam 21 and back seat crossbeam 22 are difficult to deform when bearing the ascending impact of left and right sides orientation, do benefit to the intensity that further promotes front floor structure 100, and can save the cost input and the light in weight of front seat crossbeam 21 and back seat crossbeam 22 better.
The width of the first sub-cavity 210 is greater than the width of the second sub-cavity 220, the width of the second sub-cavity 220 is greater than the width of the first sub-cavity 210, the density of the first reinforcing structures 3 in the first cavity 10 is greater than the density of the first reinforcing structures 3 in the second sub-cavity 220, and the density of the first reinforcing structures 3 in the second sub-cavity 220 is greater than the density of the first reinforcing structures 3 in the first sub-cavity 210. That is, the density of the first reinforcing structures 3 is proportional to the size of the cavity, i.e., the larger the cavity, the higher the density of the first reinforcing structures 3. Therefore, the influence of the oversized cavity on the structural strength of the center channel beam 1, the front seat cross beam 21 and the rear seat cross beam 22 can be better avoided, and the strength of the front floor structure 100 can be ensured.
According to some embodiments of the present invention, the front floor structure 100 further comprises a floor panel (not shown) disposed at the lower side of the center tunnel beam 1 and the seat cross beam 2 and connected with the center tunnel beam 1 and the seat cross beam 2, and the first reinforcement structure 3 is disposed at a distance from the floor panel. That is, a certain gap is formed between the first reinforcing structure 3 and the floor panel, so that, during electrophoresis of the front floor structure 100, a channel for electrophoresis solution to pass through can be formed between the first reinforcing structure 3 and the floor panel, so that the electrophoresis solution can flow onto the surface of the floor panel opposite to the first cavity 10 or the second cavity through the channel between the first reinforcing structure 3 and the floor panel, and then a paint film can be formed on the surface portion of the floor panel opposite to the first cavity 10 or the second cavity through an electrophoresis process. Therefore, the antirust performance of the floor panel can be better improved.
According to some alternative embodiments of the present invention, the center tunnel beam 1 is formed with a first through hole communicating with the first cavity 10, and the seat cross beam 2 is formed with a second through hole communicating with the second cavity. Therefore, in the electrophoresis process of the front floor structure 100, the electrophoresis solution can enter the first cavity 10 through the first through hole, and the electrophoresis solution can also enter the second cavity through the second through hole, so that the electrophoresis solution can be better covered on the part of the floor panel opposite to the first cavity 10 and the second cavity, and the electrophoresis effect of the floor panel can be ensured.

The center channel beam 1 and the seat cross beam 2 in the front floor structure 100 are integrally formed, so that the number of parts of the front floor assembly can be reduced better, the assembly difficulty of the front floor assembly can be reduced better, and the assembly efficiency is high.
According to the front floor assembly provided by the embodiment of the invention, the middle channel beam 1 and the seat cross beam 2 are integrally formed, so that the connection strength and the assembly efficiency of the middle channel beam 1 and the seat cross beam 2 can be better improved, the number of parts of the front floor assembly can be better reduced, the production efficiency of the front floor assembly can be favorably improved, and the integration degree is high.
