[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] It should be understood that the battery pack is placed under the center channel of the plug-in hybrid electric vehicle. In order to improve the endurance, the height of the center channel of the floor needs to be continuously raised to provide sufficient space for the placement of the battery pack and improve the endurance. Above the center channel is the footrest area. In order to improve comfort, the height of the center channel needs to be continuously lowered to increase the passenger space in the car and improve comfort, thus forming a continuous squeezing of the center channel space in both the upper and lower directions.

[0038] Among them, the side impact force transmission path of the traditional center channel structure is usually a single path, which mainly transmits force from left to right along the seat beam. At the same time, due to layout restrictions, the force transmission channel is blocked and discontinuous at the position where the seat beam begins to turn and bulge, and is prone to bending.

[0039] The embodiments of the present application provide a channel assembly structure in an automobile floor and a vehicle, which can solve the problem that the traditional force transmission channel is blocked, discontinuous and prone to bending at the corner bulge of the seat beam due to the layout restrictions of the channel structure.

[0040] First, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, an embodiment of the present application provides a channel component structure in an automobile floor, which includes: a first floor 1 and a second floor 2, wherein the first floor 1 and the second floor 2 are spaced apart along the width direction of the vehicle body; a channel floor 3, wherein the channel floor 3 is fixed between the first floor 1 and the second floor 2; a seat crossbeam 4, wherein the seat crossbeam 4 is fixed to the first floor 1 and the second floor 2 and is located above the channel floor 3, and the seat crossbeam 4 includes two corner raised areas 41; two reinforcements 5, wherein the two reinforcements 5 are located between the seat crossbeam 4 and the channel floor 3 and are fixed to the channel floor 3 at intervals along the width direction of the vehicle body, and the two ends of the reinforcements 5 are spaced apart along the width direction of the vehicle body and are both fixed to the seat crossbeam 4, and the corner raised areas 41 are located between the two ends of the corresponding reinforcements 5.

[0041] In this embodiment, the structural stability of the entire floor channel assembly is effectively enhanced by fixing the central channel floor 3 between the first floor 1 and the second floor 2, arranging the seat crossbeam 4 above the central channel floor 3, and arranging the reinforcement 5 between the seat crossbeam 4 and the central channel floor 3. The design of the reinforcement 5 makes the force transmission path no longer limited to the single seat crossbeam 4, but can be transmitted in a dispersed manner through the reinforcement 5, thereby improving the problem of the force transmission channel being obstructed, discontinuous, and bent at the raised corner position of the seat crossbeam 4, and improving the force transmission efficiency and safety during side collisions. The corner raised area 41 is located between the two ends of the reinforcement 5. This design helps to better absorb and disperse energy during a collision, reduce the intrusion of the collision into the passenger compartment, and thus improve the collision performance of the car.

[0042] Specifically, by adding two reinforcements 5, and with the corner raised area 41 of the seat crossbeam 4 located between the two ends of the reinforcements 5, a multi-path force transmission structure is formed. This no longer relies on a single force transmission path through the seat crossbeam 4, effectively improving the problem in the traditional structure where the single force transmission path is obstructed, discontinuous, and prone to bending at the raised position of the seat crossbeam 4. The reinforcements 5 can disperse the collision force transmitted at the raised position of the traditional seat crossbeam 4. The addition of the reinforcements 5 significantly enhances the connection strength between the seat crossbeam 4 and the center channel floor 3, thereby increasing the rigidity and strength of the entire center channel assembly, helping to improve the vehicle's safety performance in extreme situations such as collisions, ensuring the integrity of the passenger compartment and the safety of the occupants. The optimized force transmission path and enhanced structural strength work together to enable the vehicle to better absorb and disperse collision energy in the event of a side collision, reducing the impact on the occupants. The improved vehicle floor center channel assembly structure optimizes the force transmission path, enhances structural strength, and improves overall safety.

[0043] In combination with the first aspect, in one embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the seat cross beam 4 is provided with two arch sections 42 protruding along the height direction of the vehicle body, and the two arch sections are spaced apart along the length direction of the vehicle body. A cavity 421 is formed between the arch section 42 and the first floor 1, the middle channel floor 3 and the second floor 2; the two reinforcement members 5 are located in one of the cavities 421.

[0044] In this embodiment, the two arched sections 42 protruding along the height of the vehicle body on the seat crossbeam 4 not only increase the cross-sectional area of ​​the seat crossbeam 4 but also effectively disperse stress through their arched structure, significantly enhancing the local structural strength of the seat crossbeam 4 and the entire floor tunnel assembly. The chambers 421 formed between the arched sections 42 and the first floor panel 1, the middle tunnel floor panel 3, and the second floor panel 2 provide a well-defined force transmission path during side impacts. Furthermore, in a head-on collision, the impact force can be absorbed through these chambers 421, improving the continuity and efficiency of force transmission. The design of the chambers 421 allows these spaces to deform to absorb energy during a collision, thereby reducing the impact on the passenger compartment. Furthermore, the placement of the reinforcement 5 within the chambers 421 not only fully utilizes the space but also prevents interference between the reinforcement 5 and other components, resulting in a more compact and rational structure for the entire floor tunnel assembly.

[0045] For example, the seat crossbeam 4 can adopt a roughly M-shaped structure, forming an M-shaped cavity with the central channel floor 3, the first floor 1 and the second floor 2. Compared with the traditional "X"-shaped single cavity structure, it has better force transmission effect and stronger side collision performance.

[0046] In combination with the first aspect, in one embodiment, Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the two reinforcement members 5 form a group of reinforcement components, and there are two groups of reinforcement components. The two reinforcement components are spaced apart along the length direction of the vehicle body; the two reinforcement components correspond one-to-one to the two cavities 421 and are located in the corresponding cavities 421.

[0047] In this embodiment, by providing two sets of reinforcement assemblies, each containing two reinforcement members 5, this dual reinforcement design significantly enhances the overall structural strength of the channel assembly in the vehicle floor. This design effectively resists external impacts and protects the integrity of the passenger compartment, particularly in extreme conditions such as side impacts. The two sets of reinforcement assemblies correspond one-to-one with the two chambers 421 and are located within the corresponding chambers 421. This layout ensures a clearer and more continuous force transmission path. During a collision, the impact force can be transmitted through the reinforcement assemblies and chambers 421 in a multi-path (two force transmission channels within the reinforcement assemblies) and multi-level (force transmission guides within the sidewalls of the arched segments 42) manner, avoiding stress concentration and force transmission obstruction, thereby significantly improving the collision safety of the vehicle. Placing the reinforcement assemblies within the chambers 421 not only fully utilizes the internal space of the channel assembly in the floor, but also prevents interference between the reinforcement members 5 and other components of the floor. The design of the chambers 421 and reinforcement assemblies also enhances the vehicle's sound insulation and noise reduction. The formation of the reinforcement component and the chamber 421 can block part of the noise transmission path, reduce the interference of noise on the passenger compartment, and improve ride comfort.

[0048] In combination with the first aspect, in one embodiment, the thickness of the corner raised area 41 is greater than the thickness of the remaining area of ​​the seat cross beam 4 itself.

[0049] In this embodiment, the corner raised areas 41 are the areas of the seat crossbeam 4 most susceptible to impact and deformation during a side impact. Increasing the thickness of these areas significantly improves the seat crossbeam's strength in these critical locations, effectively resisting external impact and preventing fracture or severe deformation. During a collision, the corner raised areas 41 are subject to significant stress. Increasing the thickness of these areas better disperses stress in these areas, preventing stress concentration and structural damage. The seat crossbeam 4 is a critical component of the tunnel assembly in the vehicle floor, and its structural strength directly impacts the vehicle's crash safety. Increasing the thickness of the corner raised areas 41 significantly improves the seat crossbeam's impact resistance during a collision, thereby protecting the integrity of the passenger compartment and improving the vehicle's crash safety. While increasing the thickness may result in a certain weight increase, this design, which only locally reinforces the corner raised areas 41, minimizes the impact on the vehicle's overall weight while maintaining overall structural strength. This design achieves a balance between lightweighting and strength. Increasing the thickness of the corner raised areas 41 can be achieved by adjusting the production process and mold design.

[0050] In combination with the first aspect, in one embodiment, Figure 5 and Figure 6 As shown, the two ends of the reinforcement member 5 are far away from each other.

[0051] In this embodiment, when the ends of the reinforcement 5 are spaced apart from each other, they form a wider support surface within the cavity 421 of the seat cross member 4. This design more effectively resists impact forces from side collisions, significantly enhancing the structural stability of the entire floor tunnel assembly. The distance between the ends of the reinforcement 5 means that, during a collision, the impact force can be dispersed and transmitted over a longer path and a wider area. This design helps avoid stress concentration, ensuring more uniform and continuous force transmission, thereby improving the overall force transmission efficiency and collision safety of the structure. Because the ends of the reinforcement 5 are spaced apart from each other, they create a larger deformation space during a collision. This means that during a collision, the reinforcement 5 can absorb more energy, reducing the impact on the passenger compartment and protecting occupants. Although the distance between the ends of the reinforcement 5 may increase its overall size, this design more effectively distributes and transmits stress, thereby maintaining structural strength while reducing the weight and material consumption of the reinforcement 5 through optimized material design. The distance between the ends of the reinforcement 5 also allows for ease of installation and positioning. This design makes it easier to position and secure the reinforcement 5 to the raised corner area 41, improving production efficiency and assembly accuracy. The distance between the ends of the reinforcement 5 also enhances the vehicle's sound insulation and noise reduction. Because the reinforcement 5 forms a wider support surface within the cavity 421, it effectively blocks the noise transmission path and reduces noise interference with the passenger compartment.

[0052] In combination with the first aspect, in one embodiment, Figure 5 and Figure 6 As shown, the vehicle floor channel assembly structure includes: a channel crossbeam 6 , which is located below the channel floor 3 and fixed to the channel floor 3 .

[0053] In this embodiment, the addition of the channel crossbeam 6 forms a fixed connection with the central channel floor 3, creating a more stable frame structure. This design significantly enhances the overall structural rigidity of the channel assembly in the vehicle floor, making the entire floor structure more stable and less susceptible to deformation when subjected to load. In the event of a collision, the channel crossbeam 6 serves as an additional line of defense, absorbing and distributing the impact force, preventing it from being directly transmitted into the passenger compartment. At the same time, its fixed connection with the central channel floor 3 ensures that the two can work together to resist external impact during a collision, thereby improving the collision safety of the vehicle. The channel crossbeam 6 is located below the central channel floor 3, effectively distributing the load on the floor to other parts of the vehicle body, avoiding structural damage caused by concentrated load. This design makes the entire floor structure more durable and capable of withstanding greater loads. The fixed connection between the channel crossbeam 6 and the central channel floor 3 forms a relatively enclosed space, which, to a certain extent, blocks the propagation path of noise and reduces noise interference with the passenger compartment. Furthermore, the channel crossbeam 6 itself also serves as a sound barrier, further enhancing the vehicle's sound insulation and noise reduction performance.

[0054] In combination with the first aspect, in one embodiment, Figure 5 and Figure 6 As shown, the channel crossbeam 6 includes: two thick area sections 61 and a thin area section 62. Along the width direction of the vehicle body, the first thick area section 61, the thin area section 62 and the second thick area section 61 are connected and fixed in sequence, and the two thick area sections 61 are fixed to the central channel floor 3.

[0055] In this embodiment, the tunnel crossbeam 6 utilizes two thick sections 61 and one thin section 62, ensuring structural strength while reducing weight. The thick section 61 provides sufficient strength and rigidity to withstand external impacts and loads, while the thin section 62 reduces weight without compromising overall structural performance, achieving a lightweight design. In a collision, the two thick sections 61 serve as the primary energy-absorbing and impact-protecting structures, absorbing and distributing impact forces to protect the passenger compartment. Furthermore, their fixed connection to the central tunnel floor 3 ensures the stability and integrity of the entire floor structure during a collision. The sequential connection and fixation of the two thick sections 61 and the thin section 62 form a stable structural system. This design enhances the overall stability of the tunnel crossbeam 6, preventing deformation or damage when subjected to external forces. By rationally designing the dimensions and position of the thick and thin sections 61, 62, the stress distribution within the tunnel crossbeam 6 during load application can be optimized. The thick section 61 can withstand greater stress, while the thin section 62 can disperse stress through deformation, preventing structural damage caused by stress concentration.

[0056] In combination with the first aspect, in one embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the thin region 62 is provided with grid-like reinforcement ribs.

[0057] In this embodiment, the thin section 62 has relatively weak bending strength and impact resistance due to its thinness. By providing a grid of reinforcing ribs on the thin section 62, the local strength of this area can be significantly improved, enabling it to better withstand external loads and impacts and avoid deformation or damage. The grid-like rib design ensures more uniform stress distribution in the thin section 62 during stress. The presence of the ribs guides stress along a specific path, avoiding structural damage caused by stress concentration, thereby improving the load-bearing capacity and stability of the entire channel crossbeam 6. Although the grid-like ribs increase the material usage of the thin section 62, their unique structural design reduces overall weight while maintaining strength. Compared to increasing the overall thickness, this design is more efficient and helps achieve the goal of lightweighting the vehicle. The presence of the grid-like ribs can also enhance the vehicle's sound insulation and noise reduction performance to a certain extent. The grid structure formed by the ribs blocks the propagation path of noise, reducing noise interference in the passenger compartment and improving ride comfort.

[0058] In combination with the first aspect, in one embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the vehicle floor mid-channel assembly structure includes: two fixing bolts 7, and the fixing bolts 7 are threadedly connected to the channel crossbeam 6, the mid-channel floor 3 and the reinforcement 5 in sequence.

[0059] In this embodiment, the channel crossbeam 6, the middle channel floor 3 and the reinforcement 5 are tightly connected together by two fixing bolts 7, which can significantly enhance the connection stability of the channel assembly in the entire vehicle floor. This design ensures that the various components can work together when subjected to force, jointly resisting external impacts and loads, and avoiding loosening or separation. The threaded connection method of the fixing bolts 7 can provide a strong connection force, making the connection between the channel crossbeam 6, the middle channel floor 3 and the reinforcement 5 more secure. This design helps to improve the structural strength of the channel assembly in the entire vehicle floor, enabling it to better withstand loads and stresses under various complex working conditions. The use of fixing bolts 7 for connection can make the installation and disassembly process of the channel assembly in the vehicle floor easier. By tightening or loosening the bolts, the various components can be quickly connected or separated, improving assembly efficiency and maintenance convenience. The presence of the fixing bolts 7 can also effectively prevent the channel crossbeam 6, the middle channel floor 3 and the reinforcement 5 from being dislocated or moved during vehicle driving.

[0060] In combination with the first aspect, in one embodiment, except for the channel crossbeam 6 which is a cast aluminum part, all other parts can be stamped parts.

[0061] In combination with the first aspect, in one embodiment, the seat cross member 4 is a metal stamping part, the lower portion of which is connected to the reinforcement 5 by spot welding, and the two sides of which are connected to the first floor 1 and the second floor 2 by spot welding.

[0062] In combination with the first aspect, in one embodiment, the seat crossbeam 4 can be made of hot-formed steel, using the TRB unequal thickness hot forming stamping process, the material is HF1500+AS 75 / 75, the material thickness range is 1.6mm to 2.0mm, the yield strength after hot forming stamping range is 950~1250MPa, and the compressive strength range is 1300~1650MPa. Through the application of ultra-high strength steel of hot-formed steel, it can replace the function of ordinary strength steel and reinforced plate, so that it can reduce the use of reinforced plate while meeting the side impact performance, which has a good weight reduction effect. At the same time, since the seat crossbeam 4 adopts the unequal thickness hot forming process, compared with traditional hot forming, it can be combined with the performance requirements of different parts of the car body, and the TRB unequal thickness rolling process can be used to achieve different thicknesses in different parts (for example, such as the thickening treatment of the corner raised area 41), so as to achieve the goal of precise weight reduction.

[0063] In combination with the first aspect, in one embodiment, Figure 5 and Figure 6As shown, the reinforcement 5 can be a steel stamping part. Every two reinforcements 5 are arranged in a cavity 421 extending along the width direction of the vehicle body of the seat crossbeam 4. One side is connected to the seat crossbeam 4 by welding, and the other side is connected to the center channel floor 3 and the channel crossbeam 6 by fixing bolts 7. In addition to the traditional force transmission channel, a new force transmission channel can be constructed and connected in parallel with it to form a dual force transmission channel, which brings a qualitative improvement to the side collision performance.

[0064] In combination with the first aspect, in one embodiment, the center channel floor 3 can be a metal stamping part, the front portion of which is connected to the seat crossbeam 4 by spot welding, the two sides are connected to the first floor 1 and the second floor 2 by spot welding, and the upper portion is connected to the seat crossbeam 4 by spot welding. In order to meet the side impact performance and the second row footrest space, the center channel adopts a structure similar to a flat plate. The flat plate structure is prone to floor modal and stiffness performance problems due to the lack of reinforcement features. Usually, to solve this problem, the form of adding reinforcement plates is adopted, but this will increase the weight. Therefore, the center channel floor 3 can be made of cold stamping technology, and the material is dual-phase ultra-high strength steel, model HC820 / 1180DPD+Z 50 / 50, with a material thickness of 1.2mm, a yield strength of more than 820MPa, and a tensile strength of more than 1180MPa. Through the application of dual-phase ultra-high strength steel, the function of the ordinary strength steel reinforcement plate can be replaced, so that the use of reinforcement plates can be reduced while meeting the modal and stiffness performance, which plays a good lightweight role.

[0065] In combination with the first aspect, in one embodiment, Figure 5 and Figure 6 As shown, the channel crossbeam 6 can be a cast aluminum part, which is arranged just below the center channel floor 3 and is connected to the reinforcements 5 on the left and right of the seat crossbeam 4 by fixing bolts 7. The overall structure is thick at both ends and thin in the middle. Because the bending area of ​​the side impact channel is just near the installation point structure where the channel crossbeam 6 and the center channel floor 3 are fixed, the structure near the installation point adopts a thickened structure to ensure that no bending deformation occurs during a side impact. The thinness in the middle is mainly due to layout space limitations. Since the pipeline harness is arranged above the channel crossbeam 6 and the battery pack is arranged below it, it is necessary to adopt a structure in the form of thinning and adding grid-like reinforcement ribs to realize the structure in the extremely narrow space (10mm) between the pipeline harness and the battery pack to ensure structural reinforcement.

[0066] Second, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, an embodiment of the present application provides a vehicle, which includes a channel component structure such as a car floor, wherein the channel component structure of the car floor includes: a first floor 1 and a second floor 2, the first floor 1 and the second floor 2 are spaced apart along the width direction of the vehicle body; a center channel floor 3, the center channel floor 3 is fixed between the first floor 1 and the second floor 2; a seat crossbeam 4, the seat crossbeam 4 is fixed to the first floor 1 and the second floor 2, and is located above the center channel floor 3, the seat crossbeam 4 includes two corner raised areas 41; two reinforcements 5, the two reinforcements 5 are located between the seat crossbeam 4 and the center channel floor 3, and are fixed to the center channel floor 3 at intervals along the width direction of the vehicle body, and the two ends of the reinforcements 5 are spaced apart along the width direction of the vehicle body and are both fixed to the seat crossbeam 4, and the corner raised areas 41 are located between the two ends of the corresponding reinforcements 5.

[0067] In this embodiment, the structural stability of the entire floor channel assembly is effectively enhanced by fixing the central channel floor 3 between the first floor 1 and the second floor 2, arranging the seat crossbeam 4 above the central channel floor 3, and arranging the reinforcement 5 between the seat crossbeam 4 and the central channel floor 3. The design of the reinforcement 5 makes the force transmission path no longer limited to the single seat crossbeam 4, but can be transmitted in a dispersed manner through the reinforcement 5, thereby improving the problem of the force transmission channel being obstructed, discontinuous, and bent at the raised corner position of the seat crossbeam 4, and improving the force transmission efficiency and safety during side collisions. The corner raised area 41 is located between the two ends of the reinforcement 5. This design helps to better absorb and disperse energy during a collision, reduce the intrusion of the collision into the passenger compartment, and thus improve the collision performance of the car.

[0068] Specifically, by adding two reinforcements 5, and with the corner raised area 41 of the seat crossbeam 4 located between the two ends of the reinforcements 5, a multi-path force transmission structure is formed. This no longer relies on a single force transmission path through the seat crossbeam 4, effectively improving the problem in the traditional structure where the single force transmission path is obstructed, discontinuous, and prone to bending at the raised position of the seat crossbeam 4. The reinforcements 5 can disperse the collision force transmitted at the raised position of the traditional seat crossbeam 4. The addition of the reinforcements 5 significantly enhances the connection strength between the seat crossbeam 4 and the center channel floor 3, thereby increasing the rigidity and strength of the entire center channel assembly, helping to improve the vehicle's safety performance in extreme situations such as collisions, ensuring the integrity of the passenger compartment and the safety of the occupants. The optimized force transmission path and enhanced structural strength work together to enable the vehicle to better absorb and disperse collision energy in the event of a side collision, reducing the impact on the occupants. The improved vehicle floor center channel assembly structure optimizes the force transmission path, enhances structural strength, and improves overall safety.
