[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0034] As Figures 1 to 4 shown, the present disclosure provides a front floor structure, which is an integral structure. The front floor structure has a middle channel beam 1, a left reinforcement beam 2, a right reinforcement beam 3, a front seat crossbeam 4, a rear seat crossbeam 5, a front crossbeam 6 and a first reinforcement beam 8. Among them, the middle channel beam 1, the left reinforcement beam 2 and the right reinforcement beam 3 all extend along the first direction, and the left reinforcement beam 2 and the right reinforcement beam 3 are respectively located on both sides of the middle channel beam 1 in the second direction. The front seat crossbeam 4 and the rear seat crossbeam 5 both extend along the second direction and are spaced apart in the first direction. The middle channel beam 1, the left reinforcement beam 2 and the right reinforcement beam 3 are all connected to the front seat crossbeam 4. There are two front crossbeams 6, and the two front crossbeams 6 are respectively connected to the left reinforcement beam 2 and the right reinforcement beam 3. The two front crossbeams 6 are symmetrically arranged with respect to the middle channel beam 1, and the front crossbeam 6 is inclined with respect to the front seat crossbeam 4. A first reinforcement beam 8 is provided between the middle channel beam 1 and the left reinforcement beam 2 and between the middle channel beam 1 and the right reinforcement beam 3. The first direction and the second direction are perpendicular to each other and are located in the same plane. Among them, the first direction is the front-rear direction of the vehicle after the front floor structure is installed, and the second direction is the left-right direction of the vehicle. Specifically, the first direction is the Figure 2 ab direction in Figure 2 and the second direction is the

[0035] Understandably, by providing the middle channel beam 1, left reinforcing beam 2, right reinforcing beam 3, front seat cross beam 4, rear seat cross beam 5, front cross beam 6 and first reinforcing beam 8, the first reinforcing beam 8 is provided between the left reinforcing beam 2 and the middle channel beam 1 as well as between the right reinforcing beam 3 and the middle channel beam 1. The front cross beam 6 is inclined relative to the front seat cross beam 4, which can increase the force transmission path, enhance the structural strength of the front floor structure, facilitate the dispersion of collision energy under different pillar collision conditions of the whole vehicle, reduce the intrusion amount of the occupant and the battery, and moreover, one of the front cross beams 6 and the left reinforcing beam 2, and the other front cross beam 6 and the right reinforcing beam 3 form a stable triangular stress area, which can improve the problem of large crushing deformation at the front end of the front floor structure under small offset barrier collisions and avoid excessive occupant intrusion.

[0036] In some embodiments, the above-mentioned front floor structure is integrally die-cast. That is to say, the middle channel beam 1, left reinforcing beam 2, right reinforcing beam 3, front seat cross beam 4, rear seat cross beam 5, front cross beam 6 and first reinforcing beam 8 that constitute the front floor structure are integrally formed. The thus-formed front floor structure is an integral structure, reducing the number of parts. Moreover, integrating multiple parts into one body realizes the improvement of design and development efficiency, the reduction of process steps, the reduction of connection materials between parts, and the reduction of manufacturing costs. In addition, die-casting the front floor structure can increase the overall stiffness of the front floor structure, increase the force transmission channels on the front floor structure, improve the collision force transmission performance of the front floor structure, and is beneficial to the lightweight of the front floor structure.

[0037] Furthermore, the material of the front floor structure is aluminum alloy. That is to say, the front floor structure is die-cast using aluminum alloy material, which can improve the overall body-in-white performance while reducing the weight.

[0038] Refer to Figure 1 and Figure 2 , in some embodiments, the front cross beam 6 connected to the left reinforcing beam 2 extends in a direction away from the front seat cross beam 4 in the first direction from one end connected to the left reinforcing beam 2. That is to say, in the first direction, the distance between the front cross beam 6 and the front seat cross beam 4 gradually increases from one end connected to the left reinforcing beam 2 to the other end. Similarly, the front cross beam 6 connected to the right reinforcing beam 3 extends in a direction away from the front seat cross beam 4 in the first direction from one end connected to the right reinforcing beam 3. That is to say, in the first direction, the distance between the front cross beam 6 and the front seat cross beam 4 gradually increases from one end connected to the right reinforcing beam 3 to the other end.

[0039] With such a setting, in the small barrier offset collision condition, the left reinforcing beam 2 and the corresponding front cross beam 6 form a relatively stable triangular force-bearing area on the left side, avoiding large crushing deformation. Similarly, in the small barrier offset collision condition, the right reinforcing beam 3 and the corresponding front cross beam 6 form a relatively stable triangular force-bearing area on the right side, avoiding large crushing deformation. Moreover, with such a setting of the front cross beam 6, it can also better disperse the collision force and collision energy through the front cross beam 6, the front seat cross beam 4, and the rear seat cross beam 5 in the column collision condition, reducing the intrusion amount of the occupants and the battery.

[0040] Furthermore, referring to Figure 2 , the front floor structure also has a first floor panel 71 and a second floor panel 72 both in a triangular shape. The first floor panel 71 is connected between the front cross beam 6 and the left reinforcing beam 2; the second floor panel 72 is connected between the front cross beam 6 and the right reinforcing beam 3. By setting the first floor panel 71 and the second floor panel 72, the force transmission path can be further increased in the collision condition, the collision energy can be dispersed, and the crushing deformation can be reduced.

[0041] Furthermore, referring to Figure 1 and Figure 2 , the front floor structure also has a second reinforcing beam 9 and a third reinforcing beam 10. The second reinforcing beam 9 extends along the first direction and is connected between the front seat cross beam 4 and the rear seat cross beam 5. The third reinforcing beam 10 is connected to the second reinforcing beam 9 and extends along the second direction.

[0042] By setting the second reinforcing beam 9, the structural strength and stiffness of the front floor structure in the first direction can be enhanced, so that the collision force can be buffered and the collision energy can be dispersed in the collision in the first direction, avoiding large crushing deformation. By setting the third reinforcing beam 10, the third reinforcing beam 10 cooperates with the second reinforcing beam 9 to enhance the structural strength and stiffness of the front floor structure in the second direction, so that the collision energy can be dispersed in the collision in the second direction, reducing the crushing deformation and the intrusion amount of the occupants.

[0043] Furthermore, there are at least two second reinforcing beams 9, and two of the second reinforcing beams 9 are directly opposite to the left reinforcing beam 2 and the right reinforcing beam 3 in the first direction respectively. There are at least two third reinforcing beams 10, and each third reinforcing beam 10 is connected to the second reinforcing beam 9.

[0044] By setting at least two second reinforcing beams 9 and third reinforcing beams 10, the structural strength of the front floor structure can be further enhanced. Moreover, two of the second reinforcing beams 9 are directly opposite to the left reinforcing beam 2 and the right reinforcing beam 3 in the first direction respectively, which can directly buffer the collision force transmitted by the left reinforcing beam 2 and the right reinforcing beam 3 in the first direction, disperse the collision energy, and is beneficial to reducing the crushing deformation.

[0045] It should be noted that one end of the above-mentioned third reinforcing beam 10 in the second direction is connected to the second reinforcing beam 9, and the other end is flush with one end of the front seat cross beam 4 and / or the rear seat cross beam 5 in the second direction. With such an arrangement, in the case of a collision in the second direction, the third reinforcing beam 10 and the front seat cross beam 4 and / or the rear seat cross beam 5 can jointly bear the collision, disperse the collision force, and reduce the intrusion amount of the occupant.

[0046] Moreover, since the front floor structure is formed by die casting, the overall performance can be improved by adjusting the material thickness of the second reinforcing beam 9 and the third reinforcing beam 10 during die casting.

[0047] Exemplarily, in a specific implementation manner, referring to Figure 2 , there are two second reinforcing beams 9 and two third reinforcing beams 10. The two second reinforcing beams 9 are respectively opposite to the left reinforcing beam 2 and the right reinforcing beam 3 in the first direction. The two third reinforcing beams 10 are respectively connected to the two second reinforcing beams 9, and one end of one third reinforcing beam 10 is flush with one end of the front seat cross beam 4 in the second direction, and one end of the other third reinforcing beam 10 is flush with the other end of the front seat cross beam 4 in the second direction.

[0048] Referring to Figure 1 and Figure 2 , the above-mentioned first reinforcing beam 8 includes a bottom plate and two strip-shaped side plates. The two side plates are respectively located on both sides of the bottom plate in the first direction. The side plates are divided into two connecting sections and an intermediate section located between the two connecting sections in the second direction. One connecting section is connected to the middle channel beam 1, and the other connecting section is connected to the left reinforcing beam 2 or the right reinforcing beam 3. The width of the intermediate section is smaller than the width of the connecting section.

[0049] With such an arrangement, the connection strength between the side plates and the middle channel beam 1, the left reinforcing beam 2 or the right reinforcing beam 3 can be increased, and the overall strength of the front floor structure can be further improved.

[0050] It should be noted that one of the connecting sections of the side plate of the first reinforcing beam 8 located between the middle channel beam 1 and the left reinforcing beam 2 is connected to the middle channel beam 1, and the other connecting section is connected to the left reinforcing beam 2. One of the connecting sections of the side plate of the first reinforcing beam 8 located between the middle channel beam 1 and the right reinforcing beam 3 is connected to the middle channel beam 1, and the other connecting section is connected to the right reinforcing beam 3. In addition, one end of the bottom plate of the first reinforcing beam 8 located between the middle channel beam 1 and the left reinforcing beam 2 is connected to the middle channel beam 1, and the other end is connected to the left reinforcing beam 2. One end of the bottom plate of the first reinforcing beam 8 located between the middle channel beam 1 and the right reinforcing beam 3 is connected to the middle channel beam 1, and the other end is connected to the right reinforcing beam 3. Thus, the setting of the first reinforcing beam 8 not only increases the force transmission path, is beneficial to reducing the crushing deformation, but also can be used as a mounting point for battery installation, improving the stability of battery installation.

[0051] As Figure 1 and Figure 2 shown, the front floor structure further has a mounting crossbeam 11 disposed between the middle channel beam 1 and the left reinforcing beam 2, and a brake pedal mounting member 104 is convexly provided on the mounting crossbeam 11.

[0052] By providing the mounting crossbeam 11, not only can the overall strength of the front floor structure be enhanced, but also a brake pedal mounting member is provided, which can eliminate an additional mounting structure, further reduce the number of components, and reduce the assembly process.

[0053] Referring to Figure 1 and Figure 2 , the front floor structure further has a floor panel, and the floor panel includes a plurality of floor sub-panels; the cross-sections of the middle channel beam 1, the left reinforcing beam 2, the right reinforcing beam 3, the front seat crossbeam 4, the rear seat crossbeam 5, and the front crossbeam 6 in their respective width directions are all U-shaped, and there is a floor sub-panel between any two adjacent ones.

[0054] Understandably, the floor sub-panel between the left reinforcing beam 2 and the corresponding front crossbeam 6 is the first floor panel 71, and the floor sub-panel between the right reinforcing beam 3 and the corresponding front crossbeam is the second floor panel 72. By providing the floor panel, the gap between any two adjacent ones of the middle channel beam 1, the left reinforcing beam 2, the right reinforcing beam 3, the front seat crossbeam 4, the rear seat crossbeam 5, and the front crossbeam 6 can be filled, so as to achieve good integrity and airtightness of the front floor structure. That is to say, under the wading test condition, since the front floor structure is integrally formed, the notch problem generated in the overlapping area of the components of the traditional front floor is avoided, and the sealing requirement can be achieved on the premise of reducing the use of sealant and paint adhesive, and the problems of water ingress into the cabin and poor airtightness caused by poor sealing are solved.

[0055] Specifically, referring to Figure 2 , there is a floor sub-panel between each front crossbeam 6 and the front seat crossbeam 4; there is a floor sub-panel between the middle channel beam 1 and the left reinforcing beam 2, and this floor sub-panel is separated into three parts by the first reinforcing beam 8 and the mounting crossbeam 11. There is a floor sub-panel between the middle channel beam 1 and the right reinforcing beam 3, and this floor sub-panel is separated into two parts by the first reinforcing beam 8. There is a floor sub-panel between the front seat crossbeam 4 and the rear seat crossbeam 5, and the floor sub-panel is separated into five parts by two second reinforcing beams 9 and two third reinforcing beams 10.

[0056] It should be noted that the above floor panel is also formed when the front floor structure is die-cast, which can improve the sealing shape and ensure the connection strength. In addition, the above second reinforcing beam 9 and third reinforcing beam 10 are also U-shaped structures.

[0057] As Figure 1 and Figure 2 shown, the middle channel beam 1 has an electrical module mounting bracket 103.

[0058] Understandably, the middle channel beam 1 is provided with an electrical module mounting bracket 103, and electrical appliances of the vehicle can be mounted through the electrical module mounting bracket 103, eliminating the need for an additional mounting structure, making the integration of the front floor structure higher, further reducing the number of components, and reducing the assembly process.

[0059] Exemplarily, in a specific implementation manner, referring to Figure 2 , four of the above-mentioned electrical module mounting brackets 103 are provided, and the four electrical module mounting brackets 103 are arranged in sequence in the first direction. Alternatively, the number and position of the electrical module mounting brackets 103 can be set according to actual needs.

[0060] It should be noted that the electrical module mounting bracket 103 is located outside the U-shaped cavity of the middle channel beam 1. Specifically, after the front floor structure is installed on the vehicle, the opening of the U-shaped cavity faces downward, and the electrical module mounting bracket 103 is located at the top of the middle channel beam 1.

[0061] As Figure 1 shown, the middle channel beam 1 is also provided with a CCB bracket mounting position 105. Specifically, the CCB bracket mounting position 105 includes two mounting holes, which are formed on the middle channel beam 1 by machining after the front floor structure is die-cast. Specifically, the CCB bracket mounting position 105 is located on the side wall of the middle channel beam 1 in the second direction.

[0062] By providing the CCB bracket mounting position 105 on the middle channel beam, the CCB bracket can be mounted through the CCB bracket mounting position 105, eliminating the need for an additional mounting structure, making the integration of the front floor structure higher, further reducing the number of components, and reducing the assembly process.

[0063] As Figure 2 and Figure 3 shown, both the front seat cross beam 4 and the rear seat cross beam 5 are provided with a plurality of seat mounting seats 101.

[0064] Understandably, in the prior art, the seat mounting seats are fixed to the seat cross beam by welding. Due to the existence of machining errors and mounting errors, the consistency of the plurality of seat mounting seats is poor, and it is easy to shake after the seat is installed, resulting in poor riding comfort. However, the seat mounting seats 101 of the front floor structure are integrally formed with the front seat cross beam 4 and the rear seat cross beam 5, so that the consistency of each seat mounting seat 101 is better, the mounting stability of the seat is better, and the riding comfort can be improved.

[0065] Referring to Figure 3, after die-casting, holes can be drilled in the seat mounting base 101 and threaded bushings can be embedded, which can improve the rigidity of the seat mounting base 101 and has good sealing performance. In addition, when die-casting, the wall thickness of the seat mounting base 101 can be increased, further improving the rigidity of the seat mounting base 101 and enhancing the installation stability of the seat.

[0066] Exemplarily, referring to Figure 4 , in which, there are four seat mounting bases 101 on the front seat crossbeam 4, two in a group for mounting one seat. There are four seat mounting bases 101 on the rear seat crossbeam 5, two in a group for mounting one seat.

[0067] As Figure 2 and Figure 4 shown, there are downwardly recessed grooves 102 on both the front seat crossbeam 4 and the rear seat crossbeam 5, and battery mounting holes 51 are provided on the bottom wall of the grooves 102.

[0068] That is to say, the battery is installed on the front seat crossbeam 4 and the rear seat crossbeam 5 and is located below the front floor structure. Integrating the battery mounting position on the front floor structure in this way can eliminate the design of additional battery mounting structures and reduce the number of components. Specifically, the battery is installed on the front seat crossbeam 4 and the rear seat crossbeam 5 through bolts, where the bolts pass through the battery mounting holes 51 to connect the battery. After the bolts are connected to the battery, the heads of the bolts press against the front seat crossbeam 4 or the rear seat crossbeam 5.

[0069] In summary, the traditional front floor structure is composed of the front floor, the left front reinforcement beam of the front floor, the right front reinforcement beam of the front floor, the middle channel, the left reinforcement crossbeam, the right reinforcement crossbeam, the front seat crossbeam assembly, the rear seat crossbeam assembly, the left rear reinforcement beam of the front floor, the right rear reinforcement beam of the front floor, etc. The above-mentioned multiple stamping parts are spliced together through connection methods such as welding, mechanical connection, and bonding. The number of components is large and the structural design is complex. However, the integrally die-cast front floor structure of the present application has fewer parts and is lighter in weight. On the basis of a significant reduction in the overall weight, the overall performance state is improved. It can reduce the number of parts by 78%, reduce the connection cost by 32%, reduce the weight by 36%, reduce the investment in factory equipment and the floor space used, and improve the part lightweight design efficiency, corrosion resistance level, and manufacturing efficiency. Moreover, it includes the seat mounting base 101, the battery mounting hole 51, the electrical module mounting bracket 103, the CCB bracket mounting position 105, and the brake pedal mounting part 104, realizing the concept of integrated design.

[0070] The present disclosure also provides a vehicle including the above front floor structure. This vehicle has the beneficial effects of the front floor structure in the above embodiments and will not be elaborated here.

[0071] It should be noted that after the front floor structure is installed on the vehicle, the first direction is the front-rear direction of the vehicle, and the second direction is the left-right direction of the vehicle, that is, the width direction of the vehicle.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
