[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, 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 must be 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 enough space for 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 pressed down 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 corner bulge of the seat beam and is prone to bending.

[0039] The embodiments of the present application provide a channel component structure in a vehicle 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 a vehicle 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 in 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, wherein 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 in the width direction of the vehicle body, and the two ends of the reinforcements 5 are spaced apart in the width direction of the vehicle body and are both fixed to the seat crossbeam 4, and the corner raised area 41 is located between the two ends of the corresponding reinforcements 5.

[0041] In this embodiment, the central channel floor 3 is fixed between the first floor 1 and the second floor 2, and the seat crossbeam 4 is arranged above the central channel floor 3, and the reinforcement 5 is arranged between the seat crossbeam 4 and the central channel floor 3, so that the structural stability of the entire floor central channel assembly is effectively enhanced. The design of the reinforcement 5 makes the force transmission path no longer limited to the single seat crossbeam 4, but can be dispersedly transmitted through the reinforcement 5, which improves the problem of the force transmission channel being obstructed, discontinuous and bent at the raised position of the corner of the seat crossbeam 4, and improves 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 the corner raised area 41 of the seat cross beam 4 is located between the two ends of the reinforcement 5, a multi-path force transmission structure is formed, which no longer relies on a single force transmission path of the seat cross beam 4, effectively improving the problem that the single force transmission channel in the traditional structure is blocked, discontinuous and prone to bending at the raised position of the seat cross beam 4. The reinforcement 5 can disperse the collision force at the raised position of the traditional seat cross beam 4. The addition of the reinforcement 5 significantly enhances the connection strength between the seat cross beam 4 and the middle channel floor 3, so that the rigidity and strength of the entire middle channel assembly are improved, which helps to improve the safety performance of the vehicle in extreme situations such as collisions, and ensure 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 the collision energy in the event of a side collision, reducing the impact on the occupants. The improved structure of the automobile floor middle channel assembly optimizes the force transmission path, enhances the structural strength and improves the 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 arched sections 42 protruding along the height direction of the vehicle body, and the two arched sections are spaced apart along the length direction of the vehicle body, and a chamber 421 is formed between the arched 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 chambers 421.

[0044] In this embodiment, the two arched sections 42 protruding along the height direction of the seat cross beam 4 not only increase the cross-sectional area of ​​the seat cross beam 4, but also effectively disperse the stress through its arched structure, thereby significantly enhancing the local structural strength of the seat cross beam 4 and the entire floor channel assembly. The chamber 421 formed between the arched section 42 and the first floor 1, the middle channel floor 3 and the second floor 2 provides a good force transmission path guidance for side collision. At the same time, when the vehicle has a head-on collision, the impact force can be crushed and absorbed through these chambers 421, thereby improving the continuity and efficiency of force transmission. The design of the chamber 421 allows these spaces to deform to absorb energy during the collision, thereby reducing the impact of the collision on the passenger compartment. At the same time, placing the reinforcement 5 in the chamber 421 not only makes full use of the space, but also avoids interference between the reinforcement 5 and other parts, making the structure of the entire floor channel assembly more compact and reasonable.

[0045] Exemplarily, the seat cross beam 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 impact 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 two groups of the reinforcement components are provided. 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 chambers 421 and are located in the corresponding chambers 421.

[0047] In this embodiment, by setting two groups of reinforcement components, and each group of reinforcement components includes two reinforcement members 5, this double reinforcement design greatly improves the overall structural strength of the channel component in the automobile floor. Especially under extreme working conditions such as side collisions, this design can effectively resist external impacts and protect the integrity of the passenger compartment. The two groups of reinforcement components correspond to the two chambers 421 one by one and are located in the corresponding chambers 421. This layout makes the force transmission path clearer and continuous. When a collision occurs, the impact force can be transmitted through the reinforcement components and the chamber 421 in multiple paths (two force transmission channels of the reinforcement components) and multiple levels (force transmission guides of the side walls of the arched section 42), avoiding the problems of stress concentration and obstructed force transmission, thereby significantly improving the collision safety of the automobile. Placing the reinforcement components in the chamber 421 not only makes full use of the internal space of the channel component in the floor, but also avoids interference between the reinforcement member 5 and other parts of the floor. The design of the chamber 421 and the reinforcement components can also enhance the sound insulation and noise reduction effect of the automobile to a certain extent. The formation of the reinforcement component and the chamber 421 can block the propagation path of part of the noise, reduce the interference of noise on the passenger compartment, and improve riding comfort.

[0048] In combination with the first aspect, in one implementation, 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 area 41 is the part of the seat cross beam 4 that is most susceptible to impact and deformation when it is hit by a side collision. By increasing the thickness of these areas, the strength of the seat cross beam at these key parts can be significantly improved, thereby more effectively resisting external impact and preventing the seat cross beam from breaking or seriously deforming at these positions. During the collision, the corner raised area 41 will be subjected to greater stress. Increasing the thickness of these areas can better disperse the stress in these parts and avoid structural damage caused by stress concentration. The seat cross beam 4 is an important part of the channel assembly in the automobile floor, and its structural strength directly affects the collision safety of the automobile. By increasing the thickness of the corner raised area 41, the impact resistance of the seat cross beam 4 during the collision can be significantly improved, thereby protecting the integrity of the passenger compartment and improving the collision safety of the automobile. Although increasing the thickness may bring a certain weight increase, since this design only locally strengthens the corner raised area 41, it can minimize the impact on the overall weight of the automobile while maintaining the overall structural strength. This design achieves a balance between lightweight and strength. The increase in the thickness of the corner raised area 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 two ends of the reinforcement 5 are far away from each other, they form a wider support surface in the chamber 421 of the seat cross beam 4. This design can more effectively resist the impact force from the side collision, thereby significantly enhancing the structural stability of the channel assembly in the entire floor. The two ends of the reinforcement 5 are far away from each other, which means that when a collision occurs, the impact force can be dispersed and transmitted through a longer path and a wider area. This design helps to avoid stress concentration, making the force transmission more uniform and continuous, and improving the force transmission efficiency and collision safety of the entire structure. Since the two ends of the reinforcement 5 are far away from each other, they can form a larger deformation space during the collision. This means that when a collision occurs, the reinforcement 5 can absorb more energy, thereby reducing the impact of the collision on the passenger compartment and protecting the safety of the occupants. Although the two ends of the reinforcement 5 are far away from each other, it may increase its overall size, but since this design can more effectively disperse and transmit stress, it can reduce the weight and material consumption of the reinforcement 5 by optimizing the material design while maintaining the structural strength. The design of the two ends of the reinforcement 5 being far away from each other also takes into account the convenience of installation and positioning. This design makes it easier to position and fit the reinforcement 5 to the corner raised area 41, thereby improving production efficiency and assembly accuracy. The two ends of the reinforcement 5 are far away from each other, which can also enhance the sound insulation and noise reduction effect of the car to a certain extent. Since the reinforcement 5 forms a wider support surface in the chamber 421, they can better block the propagation path of noise and reduce the interference of noise to the passenger compartment.

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

[0053] In this embodiment, the addition of the channel crossbeam 6 forms a fixed connection with the middle channel floor 3, forming a more stable frame structure. This design significantly enhances the overall structural rigidity of the channel assembly in the automobile floor, making the entire floor structure more stable and less prone to deformation when bearing loads. In a collision accident, the channel crossbeam 6 can serve as an additional line of defense to absorb and disperse the impact force and prevent the impact force from being directly transmitted to the passenger compartment. At the same time, its fixed connection with the middle channel floor 3 also ensures that the two can work together during the collision process to jointly resist external impacts, thereby improving the collision safety of the car. The channel crossbeam 6 is located below the middle channel floor 3, which can effectively disperse the load on the floor to other parts of the car body to avoid structural damage caused by load concentration. This design makes the entire floor structure more durable and able to withstand greater loads. The fixed connection between the channel crossbeam 6 and the middle channel floor 3 can form a relatively closed space, which can block the propagation path of noise to a certain extent and reduce the interference of noise to the passenger compartment. At the same time, the channel crossbeam 6 itself can also serve as a sound insulation barrier to further enhance the sound insulation and noise reduction performance of the car.

[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 both fixed to the middle channel floor 3.

[0055] In this embodiment, the channel crossbeam 6 is designed with two thick area sections 61 and one thin area section 62, which can reduce weight while ensuring structural strength. The thick area section 61 provides sufficient strength and rigidity to resist external impact and load, while the thin area section 62 can reduce weight without affecting the overall structural performance, thereby achieving a lightweight design. In a collision accident, the two thick area sections 61 can serve as the main energy absorption and anti-collision structure to absorb and disperse the impact force and protect the safety of the passenger compartment. At the same time, their fixed connection with the middle channel floor 3 also ensures the stability and integrity of the entire floor structure during the collision. The two thick area sections 61 and the thin area section 62 are connected and fixed in sequence to form a stable structural system. This design can enhance the overall stability of the channel crossbeam 6 and prevent it from being deformed or damaged when subjected to external forces. By reasonably designing the size and position of the thick area section 61 and the thin area section 62, the stress distribution of the channel crossbeam 6 during the force-bearing process can be optimized. The thick area section 61 can withstand greater stress, while the thin area section 62 can disperse stress by deformation to avoid 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 reinforcing ribs.

[0057] In this embodiment, the thin area section 62 has relatively weak bending strength and impact resistance due to its thin thickness. By arranging grid-like reinforcement ribs on the thin area section 62, the local strength of the area can be significantly improved, so that it can better withstand external loads and impacts and avoid deformation or damage. The design of the grid-like reinforcement ribs can make the stress distribution of the thin area section 62 more uniform during the force-bearing process. The presence of the reinforcement ribs can guide the stress to be transmitted along a specific path, avoid structural damage caused by stress concentration, and thus improve the bearing capacity and stability of the entire channel crossbeam 6. Although the grid-like reinforcement ribs increase the material usage of the thin area section 62, due to its unique structural design, the overall weight can be reduced while ensuring strength. Compared with increasing the overall thickness, this design is more efficient and helps to achieve the goal of lightweighting the car. The presence of the grid-like reinforcement ribs can also enhance the sound insulation and noise reduction performance of the car to a certain extent. The grid structure formed by the reinforcement ribs can block the propagation path of the noise, reduce the interference of the noise to the passenger compartment, and improve the 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 middle channel assembly structure includes: two fixing bolts 7, and the fixing bolts 7 are threadedly connected to the channel crossbeam 6, the middle 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 automobile floor. This design ensures that the various components can work together when subjected to force, jointly resist external impacts and loads, and avoid loosening or separation. The threaded connection mode 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 automobile floor, so that it can better withstand the 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 automobile floor easier. By tightening or loosening the bolts, the rapid connection or separation of the various components can be achieved, which improves 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 the driving process of the vehicle.

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

[0061] In combination with the first aspect, in one embodiment, the seat cross beam 4 is a metal stamping part, a lower portion of which is connected to the reinforcement 5 by spot welding, and 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 cross beam 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 ranges from 950 to 1250MPa, and the compressive strength ranges from 1300 to 1650MPa. Through the application of hot-formed steel and ultra-high strength steel, the function of ordinary strength steel and reinforcement plate can be replaced, so that the use of reinforcement plate can be reduced while meeting the side impact performance, which plays a good role in weight reduction. At the same time, since the seat cross beam 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 different thicknesses can be achieved in different parts through the TRB unequal thickness rolling process (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 the traditional force transmission channel to form a double force transmission channel, which brings a qualitative improvement to the side collision performance.

[0064] Combined with the first aspect, in one embodiment, the center channel floor 3 can be a metal stamping part, the front part of which is connected to the seat cross beam 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 part is connected to the seat cross beam 4 by spot welding. The center channel adopts a structure similar to a flat plate to meet the side impact performance and the second row of footrest space. 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, the model is HC820 / 1180DPD+Z 50 / 50, the material thickness is 1.2mm, the yield strength exceeds 820MPa, and the tensile strength exceeds 1180MPa. Through the use of dual-phase ultra-high strength steel, the function of the ordinary strength steel reinforcement plate can be replaced, so that it can reduce the use of reinforcement plates while meeting the modal and stiffness performance, which plays a good role in lightweighting.

[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, arranged just below the middle channel floor 3, and connected to the reinforcements 5 on the left and right of the seat crossbeam 4 by fixing bolts 7. The overall trend 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 middle channel floor 3 are fixed, the structure near the installation point adopts a thickened structure to ensure that no bending deformation occurs during the side impact. The thinness in the middle is mainly due to the layout space limitation. Since the pipeline harness is arranged on the channel crossbeam 6 and the battery pack is arranged below it, it is necessary to adopt a structure with thinned and grid-shaped reinforcement ribs to realize the structure and ensure the structural reinforcement in the extremely narrow space (10mm) between the pipeline harness and the battery pack.

[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 in a vehicle floor, wherein the channel component structure in the vehicle floor 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, wherein 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 area 41 is located between the two ends of the corresponding reinforcements 5.

[0067] In this embodiment, the central channel floor 3 is fixed between the first floor 1 and the second floor 2, and the seat crossbeam 4 is arranged above the central channel floor 3, and the reinforcement 5 is arranged between the seat crossbeam 4 and the central channel floor 3, so that the structural stability of the entire floor central channel assembly is effectively enhanced. The design of the reinforcement 5 makes the force transmission path no longer limited to the single seat crossbeam 4, but can be dispersedly transmitted through the reinforcement 5, which improves the problem of the force transmission channel being obstructed, discontinuous and bent at the raised position of the corner of the seat crossbeam 4, and improves 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 the corner raised area 41 of the seat cross beam 4 is located between the two ends of the reinforcement 5, a multi-path force transmission structure is formed, which no longer relies on a single force transmission path of the seat cross beam 4, effectively improving the problem that the single force transmission channel in the traditional structure is blocked, discontinuous and prone to bending at the raised position of the seat cross beam 4. The reinforcement 5 can disperse the collision force at the raised position of the traditional seat cross beam 4. The addition of the reinforcement 5 significantly enhances the connection strength between the seat cross beam 4 and the middle channel floor 3, so that the rigidity and strength of the entire middle channel assembly are improved, which helps to improve the safety performance of the vehicle in extreme situations such as collisions, and ensure 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 the collision energy in the event of a side collision, reducing the impact on the occupants. The improved structure of the automobile floor middle channel assembly optimizes the force transmission path, enhances the structural strength and improves the overall safety.
