Detailed Implementation

[0048] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0049] In this disclosure, an XYZ coordinate system is established for the front floor frame and front floor assembly of this application, where the X direction is the longitudinal direction of the vehicle, referring to the direction of the line connecting the front and rear of the vehicle; the Y direction is the width direction of the vehicle; and the Z direction is the height direction of the vehicle, with the direction pointed upwards and downwards. Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0050] The first aspect of this disclosure provides a front floor frame, such as Figures 1 to 11As shown, the front floor frame includes a central aisle 11, at least two seat crossbeams 13, and a connecting beam 14. The at least two seat crossbeams 13 are arranged intersecting the central aisle 11, and adjacent seat crossbeams 13 are connected by at least one connecting beam 14. The central aisle 11, the at least two seat crossbeams 13, and the connecting beam 14 are integrally formed.

[0051] In the above embodiment, the central tunnel 11, at least two seat crossbeams 13, and connecting beam 14 are integrally formed, which reduces the number of parts in the front floor assembly and improves assembly efficiency. Furthermore, the integral formation of the central tunnel 11, at least two seat crossbeams 13, and connecting beam 14 increases the degree of integration in the front floor assembly, making it easier to ensure dimensional accuracy during assembly, reducing welding errors, and thus reducing assembly errors. In addition, the connection between adjacent seat crossbeams 13 via the connecting beam 14 improves structural strength and optimizes the force transmission path.

[0052] It should be understood that the integral molding of the central tunnel 11, at least two seat crossbeams 13, and connecting beam 14 can also improve the rigidity and strength of the front floor frame, thereby improving the vehicle's safety and collision performance.

[0053] In addition, the central channel 11, at least two seat crossbeams 13, and connecting beam 14 of the aforementioned front floor frame are integrally formed, which reduces the allowance required for welding compared to integral welding, thereby achieving the effect of weight reduction.

[0054] It should be understood that the aforementioned central channel 11, at least two seat crossbeams 13, and connecting beam 14 can be formed using any suitable molding process. For example, the central channel 11, at least two seat crossbeams 13, and connecting beam 14 can be integrally formed by hot pressing.

[0055] It should be noted that two adjacent seat crossbeams 13 are connected by at least one connecting beam 14, and the two seat crossbeams 13 can couple and transmit force, thereby improving the safety performance of side pole impact in the event of a side pole impact.

[0056] Specifically, when a vehicle is involved in a side collision, when the collision force is transmitted to one of the two seat beams 13, the seat beam 13 adjacent to that seat beam 13 and connected by the connecting beam 14 will also bear part of the collision force, increasing the force transmission path of the collision force, which is beneficial to the transmission and dispersion of the collision force and improving the collision safety performance.

[0057] Furthermore, by fixing adjacent seat beams 13 together with connecting beam 14, the collision force that would otherwise be transmitted to one of the two seat beams 13 can be transferred to the adjacent seat beam 13 during a frontal collision, thereby improving the collision safety performance of the vehicle during a frontal collision.

[0058] In addition, the connecting beam 14 connects two adjacent seat crossbeams 13 together, and the seat crossbeams 13 are not easily deformed, which well ensures the dimensional stability of the seat crossbeams 13 part of the front floor frame.

[0059] In some embodiments, the front floor frame also includes a skid plate 12 connected to at least two seat crossbeams 13, and the skid plate 12, the center tunnel 11, the at least two seat crossbeams 13 and the connecting beam 14 are integrally formed into a single frame 10.

[0060] In the above-described embodiment, the seat crossbeam 13, skid plate 12, central tunnel 11, and connecting beam 14 are integrally molded into a single frame 10. This further reduces the number of parts in the front floor assembly, increases the integration level of the front floor assembly, and makes it easier to ensure assembly accuracy during assembly. Furthermore, it further improves the rigidity and strength of the front floor frame, thereby enhancing vehicle safety and collision performance.

[0061] It should be understood that molding the seat crossbeam 13, skid plate 12, central channel 11, and connecting beam 14 into a single integrated frame 10 reduces welding errors and ensures dimensional stability compared to welding.

[0062] In some embodiments, the integrated frame 10 can be divided into multiple regions 100. The materials and plate thicknesses used in the multiple regions 100 can be designed in a targeted manner to achieve targeted design of the structural strength of different regions 100. This allows the integrated frame 10 to meet the vehicle's collision performance requirements while further reducing the weight of the integrated frame 10.

[0063] In some specific embodiments, the thickness of each region 100 among the plurality of regions 100 of the integrated frame 10 can be designed specifically according to actual needs. For example, the thickness of each region 100 among the plurality of regions 100 of the integrated frame 10 can all be different; or, at least two of the regions 100 among the plurality of regions 100 of the integrated frame 10 can have the same thickness.

[0064] Furthermore, the thickness of each of the multiple regions 100 of the integrated frame 10 can be designed specifically according to actual needs. For example, the materials of each region 100 can be designed to be different, or at least two of the regions 100 can be designed to be made of the same material, as long as the strength requirements are met.

[0065] In some implementations, such as Figure 5As shown, at least two seat crossbeams 13 include a front seat crossbeam 13a and a rear seat crossbeam 13b. A skid plate 12 is connected to the front seat crossbeam 13a. The integrated frame 10 has multiple regions 100, including a first region 101, a second region 102, and a third region 103 distributed sequentially along the front-rear direction of the vehicle. The first region 101 includes at least a portion of the skid plate 12 and the front structure of the central tunnel 11 located in front of the front seat crossbeam 13a. The second region 102 includes the front seat crossbeam 13a, and the third region 103 includes the rear seat crossbeam 13b. A connecting beam 14 is located in the second region 102 and / or the third region 103.

[0066] In some specific embodiments, the connecting beam 14 is partially located in the second region 102 and partially located in the third region 103. For example... Figure 5 As shown, the first region 101, the second region 102, and the third region 103 of the integrated frame 10 can be assembled together by laser welding and then integrally formed by stamping. The thickness of the second region 102 can be less than the thickness of the first region 101, and the thickness of the second region 102 can be less than the thickness of the third region 103.

[0067] In the above embodiment, the skid plate 12 of the first region 101 is fixedly connected to the front engine compartment longitudinal beam 90. When the vehicle is subjected to a 100% frontal collision and a 40% offset collision, the collision force will be transmitted to the skid plate 12 of the first region 101 through the front engine compartment longitudinal beam 90. In order to cope with the 100% frontal collision and the 40% offset collision, the thickness of the skid plate 12 of the first region 101 is appropriately increased to improve the structural strength of the skid plate 12. The rear seat crossbeam 13b of the third region 103 of the integrated frame 10 is mainly responsible for side pole impacts. Therefore, the thickness of the rear seat crossbeam 13b and part of the connecting beam 14 of the third region 103 can be appropriately increased to improve the structural strength of the rear seat crossbeam 13b and part of the connecting beam 14. When the force of a 100% frontal collision and the force of a 40% offset collision are transmitted to the second region 102 of the integrated frame 10, the collision force has been reduced. Furthermore, the collision point on the side of the vehicle is usually not in the second region 102 of the integrated crossbeam. Therefore, the front seat crossbeam 13a and the connecting beam 14 of the second region 102 of the integrated frame 10 can be appropriately thinner than the first region 101 and the second region 102, so as to achieve a lightweight design of the integrated frame 10 while ensuring the structural strength of the integrated frame 10.

[0068] It should be understood that the front seat crossbeam 13a and the rear seat crossbeam 13b can be used for the installation of the vehicle's front seats, which will not be elaborated here.

[0069] Furthermore, the first region 101, the second region 102, and the third region 103 of the aforementioned integrated frame 10 can be made of suitable materials according to actual needs, as long as they meet the required strength requirements, which will not be elaborated here.

[0070] In some implementations, such as Figure 2 and Figure 3 As shown, at least two seat crossbeams 13 include a front seat crossbeam 13a and a rear seat crossbeam 13b. The front seat crossbeam 13a includes two opposing first vertical walls 13a1 and a first cavity 13a2 located between the two first vertical walls 13a1 and extending along the width direction of the vehicle. The central tunnel 11 includes two opposing second vertical walls 112 and a second cavity 113 located between the two second vertical walls 112 and extending along the length direction of the vehicle. The first cavity 13a2 and the second cavity 113 are arranged intersectingly, such that the second vertical wall 112 has a break 40, and a reinforcing plate 30 is provided at the break 40. The reinforcing plate 30 is connected to the second vertical wall 112 so that the reinforcing plate 30 and the connected second vertical wall 112 form a first force transmission path in the front-rear direction of the vehicle. On the one hand, the setting of the reinforcing plate 30 can improve the stiffness of the middle part of the front crossbeam 13a of the seat, thereby improving the mode of the seat and improving the comfort of the front seat. On the other hand, the structure in front of the front crossbeam 13a of the second vertical wall 112 of the central channel 11 and the structure behind the front crossbeam 13a of the seat are connected by the reinforcing plate 30, so that the continuity of strength of the central channel 11 in the part of the front crossbeam 13a of the seat and the part of the rear crossbeam 13b of the seat is guaranteed.

[0071] In the above embodiment, the reinforcing plate 30 and the connected second vertical wall 112 form a first force transmission path along the front-rear direction of the vehicle. When the vehicle is involved in a collision, this arrangement enables the collision force to be transmitted more efficiently from the portion of the central channel 11 located in the front crossbeam 13a of the seat to the portion of the central channel 11 located in the rear crossbeam 13b of the seat, so as to more effectively transmit the collision force transmitted to the central channel 11 to the rear crossbeam 13b of the seat for dispersion.

[0072] In some embodiments, the central channel 11 is provided with a plurality of first force transmission ribs 111, which are arranged side by side along the width direction of the vehicle and extend along the front-rear direction of the vehicle. On the one hand, the provision of the first force transmission ribs 111 can improve the structural strength of the central channel 11; on the other hand, each of the first force transmission ribs 111 on the central channel 11 can construct a force transmission path. When the front of the vehicle is hit by a collision, the collision force is transmitted to the end of the central channel 11 away from the seat crossbeam 13, and can be dispersed and efficiently transmitted to the seat crossbeam 13 to reduce damage to the central channel 11.

[0073] like Figure 1As shown, two first force transmission ribs 111 are provided on the central channel 11. The two first force transmission ribs 111 are arranged side by side along the width direction of the vehicle and extend along the front-rear direction of the vehicle. The two first force transmission ribs 111 extend along the front-rear direction of the vehicle to the front crossbeam 13a of the seat. When the front of the vehicle is hit by a collision, the impact force is transmitted to the end of the central channel 11 away from the seat crossbeam 13, and can be dispersed and efficiently transmitted to the seat crossbeam 13 to reduce damage to the central channel 11.

[0074] In some embodiments, the central channel 11 includes a front region located in front of the front crossbeam 13a of the seat, and a plurality of first force-transmitting ribs 111 extend from the front end of the front region to the front crossbeam 13a of the seat. These ribs guide the impact force at the front end of the central channel 11 to be transmitted along the first force-transmitting ribs 111 to the front crossbeam 13a of the seat, thereby improving the efficiency of the impact force transmission from the front end of the central channel 11 to the front crossbeam 13a of the seat. In addition, the impact force received by the central channel 11 is dispersed by transmitting it to the front crossbeam 13a of the seat, which can also reduce the damage to the front structure of the central channel 11 caused by the impact force.

[0075] In some embodiments, the position of the first force transmission rib 111 can be arbitrarily set. For example, the central channel 11 also includes a first plate 114 located between two second vertical walls 112. At least a portion of the second vertical walls 112 and at least a portion of the first plate 114 can be connected by the first force transmission rib 111. By having the first force transmission rib 111 and the second vertical walls 112 work together to transmit force, the transmission efficiency of the collision force along the second vertical walls 112 is improved. This allows the collision force at the front end of the central channel 11 to be transmitted to the reinforcing plate 30 more quickly along the first force transmission path, and the force continues to be transmitted to the rear end of the central channel through the second vertical walls 112 of the central channel 11.

[0076] like Figure 6 and Figure 7 As shown, the central channel 11 includes two second vertical walls 112 spaced apart along the width direction of the vehicle. Each second vertical wall 112 and the reinforcing plate 30 connected to the second vertical wall 112 can form a first force transmission path. In addition, the portion of the second vertical wall 112 located in the front structure of the central channel 11 is connected to the first force transmission rib 111. The first force transmission rib 111 and the second vertical wall 112 cooperate to transmit force, thereby improving the force transmission efficiency.

[0077] In some implementations, such as Figure 1 , Figure 10 and Figure 11 As shown, the front end of the skid 12 away from at least two seat crossbeams 13 is provided with a flange 122 extending along the width direction of the vehicle. The flange 122 is used to fit and connect to the front engine compartment longitudinal beam 90. It should be understood that the flange 122 is fixedly connected to the front engine compartment longitudinal beam 90 so that the force of the front engine compartment longitudinal beam 90 can be transmitted to the skid 12.

[0078] In the above embodiment, the skid plate 12 and the forward engine compartment longitudinal beam 90 are connected by fasteners 200. Compared to the traditional method of fixing the skid plate 12 and the forward engine compartment longitudinal beam 90 by welding, the fasteners 200 improve the connection strength between the skid plate 12 and the forward engine compartment longitudinal beam 90, allowing the impact force of the forward engine compartment longitudinal beam 90 to be transmitted to the skid plate 12 to the greatest extent. Furthermore, the increased connection strength between the skid plate 12 and the forward engine compartment longitudinal beam 90 also improves the bending resistance of the area 100 where the forward engine compartment longitudinal beam 90 connects to the skid plate 12.

[0079] In the above embodiments, the fastener 200 can be constructed arbitrarily. For example, the fastener 200 can be constructed as a bolt, nut, or screw, and there is no limitation here.

[0080] In some implementations, such as Figure 1 and Figure 10 As shown, the skid plate 12 includes multiple second force transmission ribs 121. These multiple second force transmission ribs 121 are arranged side by side along the width direction of the vehicle and extend along the front-rear direction of the vehicle. On the one hand, they can improve the bending resistance of the skid plate 12 and effectively suppress the deformation of the foot area and reduce the intrusion of the pedal area in the event of a frontal collision. On the other hand, each second force transmission rib 121 forms a force transmission path. In the event of a frontal collision, the impact force on the front engine compartment longitudinal beam 90 can be efficiently transmitted to the rear along the multiple second force transmission ribs 121 on the skid plate 12 after being transmitted to the skid plate 12.

[0081] like Figure 1 and Figure 10 As shown, two second force transmission ribs 121 are arranged side by side along the width direction of the vehicle on the skid plate 12. The two second force transmission ribs 121 extend along the front-rear direction of the vehicle to the front crossbeam 13a of the seat, so that the impact force transmitted from the front longitudinal beam of the engine compartment to the skid plate 12 can be efficiently transmitted to the front crossbeam 13a of the seat for dispersion, thereby reducing damage to the skid plate 12.

[0082] In some implementations, such as Figures 1 to 4 As shown, the front floor frame also includes an energy-absorbing structure 20, which is connected to both ends of at least one of the two seat crossbeams 13. The energy-absorbing structure 20 is used to connect to the sill beam. In the event of a severe side collision, the energy-absorbing structure 20 connecting the sill beam and the seat crossbeam 13 will collapse to absorb energy, thereby protecting the seat crossbeam 13 and thus protecting the integral frame 10 in the front floor frame. Moreover, when the energy-absorbing structure 20 collapses due to a side collision, only the energy-absorbing structure 20 needs to be replaced, resulting in low cost.

[0083] In the above-described embodiments, such as Figure 1and Figure 4 As shown, the energy-absorbing structure 20 includes a second plate 21 extending along the extension direction of the seat crossbeam 13. At least one bent portion 22 is provided on the second plate 21 of the energy-absorbing structure 20, which is recessed in the second plate 21 and / or protrudes outward from the second plate 21, so as to facilitate the collapse and energy absorption of the energy-absorbing structure 20.

[0084] In some embodiments, the connection between the energy-absorbing structure 20 and the seat crossbeam 13 is varied. For example, the energy-absorbing structure 20 can be detachably connected to the seat crossbeam 13, allowing for easy replacement of the energy-absorbing structure 20 if it is damaged. The connection between the energy-absorbing structure 20 and the seat crossbeam 13 can be made using screws or bolts, and there is no limitation on this.

[0085] In other embodiments, the energy-absorbing structure 20 can be connected to the seat crossbeam 13 by welding points, which facilitates the replacement of the energy-absorbing structure 20 after it is damaged.

[0086] It should be understood that the energy-absorbing structure 20 should be made of a material that is more easily deformable than the seat beam 13. When manufacturing, the appropriate material can be selected according to the actual needs, which will not be elaborated here.

[0087] In some embodiments, the seat beam 13 includes seat mounting sections 132 located on opposite sides of the central channel 11. A first seat mounting seat 80 is provided on the seat mounting section 132, and a second seat mounting seat 70 is provided on the energy-absorbing structure 20. A reinforcing portion 131 located between the first seat mounting seat 80 and the second seat mounting seat 70 is also provided on the seat mounting section 132.

[0088] In the above embodiments, the first seat mounting base 80 and the second seat mounting base 70 can be used to mount the front seat of the same vehicle. The reinforcing part 131 provided on the seat mounting section 132 can effectively suppress the lifting of the first seat mounting base 80 when the vehicle is involved in a side pole collision, so that the driver's seating position can maintain good stability when a collision occurs.

[0089] like Figure 5 As shown, both the front seat crossbeam 13a and the rear seat crossbeam 13b in the front floor frame have seat mounting sections 132, and the front seat crossbeam 13a has two seat mounting sections 132.

[0090] Furthermore, the seat mounting section 132 is connected to the skid plate 12 and the connecting beam 14 respectively. The projections of the reinforcing part 131, the connecting beam 14, and the skid plate 12 on the same side of the central tunnel 11 in the longitudinal direction of the vehicle at least partially overlap. Through the above arrangement, on the one hand, the projections of the skid plate 12 and the connecting beam 14 on the same side of the central tunnel 11 in the longitudinal direction of the vehicle at least partially overlap, which can form a second force transmission path, making it more conducive to the transmission of the impact force on the skid plate 12 to the connecting beam 14, that is, the impact force on the skid plate 12... The impact force is transmitted to the connecting beam 14 more efficiently. On the other hand, when the projections of the reinforcing part 131, the connecting beam 14 and the skid plate 12 on the same side are at least partially overlapped in the longitudinal direction of the vehicle, the reinforcing part 131 is at least partially located on the second force transmission path where the skid plate 12 and the connecting beam 14 are located. The impact force on the skid plate 12 can be transmitted to the connecting beam 14 through the seat mounting beam. The reinforcing part 131 can improve the structural strength of the seat crossbeam 13 and prevent the seat crossbeam 13 from deforming during the force transmission process.

[0091] In some implementations, such as Figure 6 and Figure 7 The snowboard 12 is provided with two second force transmission ribs 121 extending along the length direction of the vehicle and spaced apart along the width direction of the vehicle. This improves the force transmission efficiency of the second force transmission path located on the snowboard 12, so that the impact force transmitted from the front engine compartment longitudinal beam 90 to the snowboard 12 can be efficiently transmitted to the front seat crossbeam 13a for dispersion, thereby reducing damage to the snowboard 12.

[0092] In some specific implementation methods, such as Figures 1 to 6As shown, the integrated frame 10 in the front floor frame includes a central tunnel 11, a front seat crossbeam 13a, a rear seat crossbeam 13b, two skid plates 12, and two connecting beams 14 disposed between the front seat crossbeam 13a and the rear seat crossbeam 13b. The central tunnel 11 extends along the longitudinal direction of the vehicle and intersects with both the front seat crossbeam 13a and the rear seat crossbeam 13b. The second cavity 113 of the central tunnel 11 and the first cavity 13a2 of the front seat crossbeam 13a are intersected. A reinforcing plate 30 is disposed at the break 40 of the second vertical wall 112 of the central tunnel 11, and the reinforcing plate 30 is connected to the first vertical wall 13a1 of the two front seat crossbeams 13a. Two skids 12 are respectively positioned on both sides of the central aisle 11 along the width of the vehicle. The two skids 12 extend along the front and rear of the vehicle to the front seat crossbeam 13a. The end of either skid 12 furthest from the front seat crossbeam 13a overlaps with the front engine compartment longitudinal beam 90. Mounting holes 122a are provided on the flange 122 of the skid 12. The skid 12 and the front engine compartment longitudinal beam 90 are fixedly connected by fasteners 200, which are bolts. The skid 12 can be extended within an appropriate range to allow for a longer overlap between the skid 12 and the front engine compartment longitudinal beam 90. The connection between the skid 12 and the front engine compartment longitudinal beam 90 is then achieved by bolts, which significantly improves the bending strength of the area on the front engine compartment longitudinal beam 90 where it connects to the skid 12. The number of bolts connecting the skid 12 and the front engine compartment longitudinal beam 90 can be set according to actual needs and is not limited here.

[0093] In addition, each skid plate 12 is provided with two second force transmission ribs 121 spaced apart along the width direction of the vehicle. Each second force transmission rib 121 is arranged side by side along the width direction of the vehicle and extends to the front crossbeam 13a of the seat along the front-rear direction of the vehicle. The skid plates 12 and the connecting beam 14 on the same side of the central tunnel 11 at least partially overlap in the front-rear direction of the vehicle. The central tunnel 11, the two skid plates 12, the front crossbeam 13a of the seat, the rear crossbeam 13b of the seat, and the connecting beam 14 of the integrated frame 10 are divided into three areas 100. The plates of the three areas 100 are first welded together by laser welding and then integrally formed by hot stamping. In addition, the integrated frame 10 is also provided with a slide rail connection hole 300 for the sub-instrument panel. Compared with the traditional method of mounting the slide rail connection hole 300 of the sub-instrument panel on two parts, mounting the slide rail connection hole 300 of the sub-instrument panel on the integrated frame 10 can ensure the consistency and stability of the dimensions of the slide rail connection hole 300 of the sub-instrument panel.

[0094] In addition, the front floor frame also includes an energy-absorbing structure 20. Both ends of the front seat crossbeam 13a and the rear seat crossbeam 13b are connected to the sill beam 50 through the energy-absorbing structure 20 for energy absorption during a side collision of the vehicle, so as to protect the integrated frame 10. The front crossbeam 13a has two seat mounting sections 132 with first seat mounting seats 80, and the energy-absorbing structures 20 at both ends of the front crossbeam 13a each have a second seat mounting seat 70. Each seat mounting section 132 of the front crossbeam 13a has a reinforcing part 131, and each reinforcing part 131 is located between the first seat mounting seat 80 and the second seat mounting seat 70. The rear crossbeam 13b has two seat mounting sections 132 with first seat mounting seats 80, and the energy-absorbing structures 20 at both ends of the rear crossbeam 13b each have a second seat mounting seat 70. Each seat mounting section 132 of the front crossbeam 13a has a reinforcing part 131, and each reinforcing part 131 is located between the first seat mounting seat 80 and the second seat mounting seat 70. The first seat mounting seats 80 and the second seat mounting seats 70, which are located on the same side of the central tunnel 11 and are located on the front crossbeam 13a, the rear crossbeam 13b, and the energy-absorbing structure 20, are used to mount a front seat of the vehicle.

[0095] A second aspect of this disclosure provides a front floor assembly including a front floor panel 60 and a front floor frame as provided in the first aspect of this disclosure, the front floor frame being disposed above the front floor panel 60. The front floor panel 60 and the front floor frame can be connected together by spot welding.

[0096] In some embodiments, the front floor panel 60 is located below the front floor frame 1 and covers the front floor frame 1 in the width direction of the vehicle. This arrangement, with the front floor frame positioned above the front floor panel and the panel covering it in the width direction, preserves the integrity of the front floor panel and effectively solves the problem of seal failure caused by multi-piece front floor panels in related technologies. Furthermore, by primarily creating mounting holes on the integrated frame 10, the integrity of the front floor panel 60 is further improved, reducing the occurrence of seal failure.

[0097] Furthermore, the connecting beam 14 provided between the front crossbeam 13a and the rear crossbeam 13b of the seat can strengthen the panel in the area between the two crossbeams 13, thereby increasing the local stiffness of the front floor panel 60 between the two crossbeams 13, so as to reduce the vibration of the front floor panel 60 in this area, and thus reduce the amount of damping film used in the front floor panel 60.

[0098] In addition, such as Figure 9As shown, the front floor panel 60 has a recessed clearance channel 63 facing the central channel 11, which can be used to avoid components such as pipes located below the clearance channel 63, so as to facilitate the arrangement of pipes below the clearance channel 63.

[0099] In some implementations, such as Figure 8 As shown, the front floor panel 60 has a mounting area opposite to the front floor frame 1 and a covering area 61 located outside the mounting area. The covering area 61 is provided with a reinforcing structure 62, which can be used to improve the structural strength of the front floor panel 60 at the covering area 61.

[0100] In addition, the skid plate 12 and the seat crossbeam 13 are two of the main force transmission structures when the vehicle is involved in a collision. The skid plate 12 and the seat crossbeam 13 usually need to withstand a large force when a collision occurs. In order to prevent the area on the front floor panel 60 opposite to the skid plate 12 and the seat crossbeam 13 from being easily deformed when the vehicle is involved in a collision, the front floor panel 60 may have reinforcing ribs 64 opposite to the seat crossbeam 13 and the skid plate 12 connected to the seat crossbeam 13, so as to increase the structural strength of the area on the front floor panel 60 opposite to the skid plate 12 and the seat crossbeam 13.
