[0039] For automobile manufacturers, the development cycle of modern automobiles is getting shorter and shorter. How to improve the versatility of vehicle parts so that they can be suitable for different car models as much as possible and connect with parts of different structures has become a focus of automobile manufacturers.

[0040] With reference to Figure 1 , the present application provides a vehicle 100. The vehicle 100 includes a front floor 1 and a rear floor 2 that are connected. With reference to Figures 2 , 3 and 6 , the front floor 1 of the present application includes a front floor body 11 and a front interface structure 12. The front floor body 11 includes an upper surface 115, a lower surface 111 and a first side 112 extending along a first direction X. The front interface structure 12 is concave upward or convex downward from the lower surface 111, extends along a second direction Y, and includes an opening 121 provided on the first side 112. Correspondingly, the rear floor 2 includes a rear interface structure 21 that cooperates with the front interface structure 12. The front interface structure 12 is connected to the rear interface structure 21, so that the rear floor 2 and the front floor 1 are connected along the second direction Y.

[0041] The front interface structure 12 of the front floor panel 1 of the present application is provided with an opening 121, so that the rear floor panel 2 can enter the front interface structure 12 through the opening 121 along the second direction Y, or the front interface structure 12 of the front floor panel 1 can enter the rear interface structure 21 along the second direction Y starting from the opening 121. The relative position between the rear floor panel 2 and the front floor panel 1 can be adjusted by adjusting the depth of fit between the front interface structure 12 and the rear floor panel 2. Compared to a front interface structure 12 that is closed in the second direction Y, the front interface structure 12 of the present application has lower requirements for the shape fit of the rear interface structure 21. The versatility of the front floor panel 1 is improved, which facilitates the use of the same front interface structure 12 to connect rear floor panels 2 of different sizes and shapes.

[0042] The connection and fixation between the front interface structure 12 and the rear floor 2 can be achieved by welding, threaded connection, clamping, etc., and can be achieved in one or more different ways, which is not limited in this application.

[0043] In various embodiments of the present application, the first direction X is different from the second direction Y. In the embodiment shown in Figure 6, the first direction X is perpendicular to the second direction Y. In other embodiments, the first direction X and the second direction Y can be at any angle, and the present application does not limit this.

[0044] As shown in Figure 6, the front floor panel body 11 includes a functional area 113 and a connection area 114. The connection area 114 is located between the first side 112 and the functional area 113. The functional area 113 is used to connect to the front seats (not shown) of the vehicle 100. The front interface structure 12 is located in the connection area 114. In other words, where the front interface structure 12 is located, the front floor panel 1 does not serve any other functional purpose; the connection area 114 serves solely to mate with the rear floor panel 2. This allows for an adjustable distance between the rear interface structure 21 and the front interface structure 12 in the second direction Y without affecting subsequent component connections in the vehicle 100. Furthermore, since the connection area 114 serves solely as a connection and the front interface structure 12 includes an opening 121, if the dimensions of the front floor panel 1 in the second direction Y need to be changed, assemblers can reduce the dimensions by removing portions of the connection area 114 without affecting the assembly function of the front floor panel 1. With this arrangement, the adjustment flexibility of the front floor 1 is improved, and the size of the connection area 114 can be adjusted to match the vehicle 100 of different sizes or the rear floor 2 of different sizes.

[0045] The front floor panel body 11 includes an upper surface 115 opposite the lower surface 111. It should be noted that the functional area 113 can be connected to the front seats of the vehicle 100 directly or indirectly. In a direct connection embodiment, the front floor panel 1 is directly connected to the upper surface 115. In an indirect connection embodiment, the upper surface 115 is connected to a structure such as a crossbeam, and the seats are connected to the crossbeam. This arrangement requires less strength for the front floor panel 1.

[0046] Because the thickness of the connection area 114 at the location of the rear floor 2 is the sum of the thickness of the rear floor 2 and the thickness of the connection area 114, the strength of the connection area 114 is improved. To enhance the strength of the functional area 113, the functional area 113 can be provided with reinforcing ribs 1131 to ensure the supporting strength of the front floor 1.

[0047] The connection area 114 includes an edge 1141 located near the functional area 113. The distance between the side of the front interface structure 12 facing away from the opening 121 and the edge 1141 is greater than or equal to 10 mm and less than or equal to 40 mm. In this embodiment, the front interface structure 12 extends as far as possible along the second direction Y as possible across the connection area 114, allowing for greater adjustability of the mating distance between the rear floor panel 2 and the front interface structure 12, thereby improving the flexibility of the front floor panel 1. Furthermore, as described above, assemblers can cut the front floor panel body 11 along the first direction X according to actual needs. Therefore, extending the front interface structure 12 as far as possible also allows for greater dimensional adjustability of the front floor panel body 11 and helps ensure a stable connection between the front floor panel 1 and the rear floor panel 2. The distance between the side of the front interface structure 12 facing away from the opening 121 and the edge 1141 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, or 40 mm.

[0048] As shown in Figures 7 and 8, in some embodiments, the width W2 of the front interface structure 12 in the first direction X is greater than or equal to 45 mm and less than or equal to 65 mm. Increasing the width W2 can increase the contact area between the front interface structure 12 and the rear interface structure 21, allowing the front interface structure 12 to limit the movement of the front floor panel 1 and the rear floor panel 2 in the first direction X. However, further increasing the width W2 weakens the connection stability between the front interface structure 12 and the rear interface structure 21. Therefore, the width W2 within this range can increase the contact area between the front interface structure 12 and the rear interface structure 21 while ensuring connection stability. The width W2 can be 45 mm, 50 mm, 55 mm, 60 mm, or 65 mm.

[0049] It should be noted that there can be only one front interface structure 12, or, as shown in FIG6 , multiple front interface structures 12 can be provided, spaced apart along the first direction X. The provision of multiple front interface structures 12 enables connection with the rear interface structure 21 at multiple locations, improving the stability of the connection. The limited width W2 allows the front floor panel 1 to be provided with as many front interface structures 12 as possible.

[0050] Furthermore, in an embodiment where the front interface structure 12 includes multiple front interface structures, the distances between different front interface structures 12 and the edge 1141 may be the same or different, and the present application does not limit this.

[0051] The following will describe the technical solution of the front interface structure 12 provided by the present disclosure being recessed upward from the lower surface 111 in conjunction with specific embodiments. As shown in FIG7 , in some embodiments, the depth D2 of the front interface structure 12 recessed upward from the lower surface 111 is greater than or equal to 3 mm and less than or equal to 6 mm. Increasing the recess depth D2 can improve the connection stability between the front interface structure 12 and the rear interface structure 21, and prevent relative movement between the front floor 1 and the rear floor 2 in the first direction X. However, further increasing the recess depth D2 does not further help improve the connection stability, and at the same time occupies space in the vehicle 100 in the thickness direction of the front floor 1, affecting the connection of other components. Therefore, the recess depth D2 within this range can balance the connection stability between the front floor 1 and the rear floor 2, while also optimizing the size and volume of the front floor 1. The recess depth D2 can be 3 mm, 4 mm, 5 mm, or 6 mm.

[0052] It should be noted that the cooperation between the front interface structure 12 and the rear interface structure 21 can be understood as the front interface structure 12 being recessed upward from the lower surface 111, and the rear interface structure 21 being provided with a corresponding protrusion facing the lower surface 111. Therefore, the width W2 and recess depth D2 applicable to the front interface structure 12 also apply to the rear interface structure 21.

[0053] Furthermore, if there are multiple front interface structures 12, the number of rear interface structures 21 can be the same as the number of front interface structures 12, thereby maximizing the connection strength between the rear floor panel 2 and the front floor panel 1. Alternatively, the number of rear interface structures 21 can be less than the number of front interface structures 12. This is not a limitation in the present application.

[0054] The front interface structure 12 is recessed upward from the lower surface 111 and may be configured as a groove. The upper surface 115 is configured as a flat surface corresponding to the location of the front interface structure 12. As shown in Figure 7, in some embodiments, the front interface structure 12 is recessed upward from the lower surface 111 and protrudes from the upper surface 115. In this embodiment, the thickness of the front floor panel 11 varies uniformly along the first direction X, improving the uniformity of strength at all locations. This configuration effectively prevents increased stress at locations where wall thickness changes, leading to stress fatigue, thereby effectively improving the overall strength and service life of the front floor panel 11.

[0055] The vehicle 100 also includes a pipeline 6. The pipeline 6 referred to in this application should be regarded as a macroscopic connecting pipeline, such as a water pipe for connecting liquids, or an electric wire for realizing electrical connection. These structures are installed on one side of the lower surface 111 of the front floor 1. In order to increase the installation space of the pipeline 6, in some embodiments, the front floor 1 also includes a yield structure 13 that is recessed upward from the lower surface 111. The yield structure 13 extends along the second direction Y. The front interface structure 12 is also arranged on the bottom wall of the yield structure 13. As shown in Figure 7, by providing the yield structure 13, the pipeline 6 can be accommodated in the yield structure 13 to avoid the phenomenon that the pipeline 6 is blocked due to small gaps between components.

[0056] Furthermore, the rear floor panel 2 is also provided with a corresponding protrusion structure that engages with the clearance structure 13, and the rear interface structure 21 is also provided on the protrusion structure. Providing as many front interface structures 12 as possible on the front floor panel body 11 can improve the connection strength and stability between the front floor panel 1 and the rear floor panel 2, and prevent relative movement between the front floor panel 1 and the rear floor panel 2 in the first direction X.

[0057] Referring to Figure 7, in some embodiments, the recess depth D1 of the recessed structure 13 from the lower surface 111 upward is greater than or equal to 30 mm and less than or equal to 40 mm. The increase in the recess depth D1 can increase the space vacated by the front floor 1, making the placement space of the pipeline 6 more spacious and the layout flexibility of the pipeline 6 higher. However, if the recess depth D1 is too large, the size of the front floor 1 in the thickness direction will be too high, compressing the setting position of other components of the vehicle 100. The present application limits the recess depth D1 to this size range, so that the front floor 1 can avoid a sufficient size without excessively increasing the volume. The recess depth D1 can be 30 mm, 32 mm, 34 mm, 36 mm, 38 mm or 40 mm.

[0058] In some embodiments, the width W1 of the clearance structure 13 in the first direction X is greater than or equal to 245 mm and less than or equal to 265 mm. The width W1 of the clearance structure 13 increases the placement width of the pipeline 6 and improves the layout flexibility of the pipeline 6. However, if the width W1 is too large, the space available for components on the upper surface 115 side of the front floor 1 will be reduced. Therefore, the width W1 within this range can balance the clearance space on the lower surface 111 side of the front floor 1 and the installation space on the upper surface 115 side. The width W1 can be 245 mm, 250 mm, 255 mm, 260 mm, or 265 mm.

[0059] The following will describe the technical solution for the front interface structure 12 protruding downward from the lower surface 111 with reference to the above-mentioned embodiments. As shown in Figure 8, in some embodiments, the depth D3 of the front interface structure 12 protruding downward from the lower surface 111 is greater than or equal to 3 mm and less than or equal to 6 mm. Increasing the protrusion depth D3 can improve the connection stability between the front interface structure 12 and the rear interface structure 21, and prevent relative movement between the front floor 1 and the rear floor 2 in the first direction X. However, further increasing the protrusion depth D3 does not further improve the connection stability, and at the same time occupies space in the vehicle 100 in the thickness direction of the front floor 1, affecting the connection of other components. Therefore, the protrusion depth D3 within this range can balance the connection stability between the front floor 1 and the rear floor 2, while also optimizing the size and volume of the front floor 1. The protrusion depth D3 can be 3 mm, 4 mm, 5 mm, or 6 mm.

[0060] It should be noted that the cooperation between the front interface structure 12 and the rear interface structure 21 can be understood as the front interface structure 12 protruding downward from the lower surface 111, and the rear interface structure 21 having a downward recess at the corresponding position. Therefore, the width W2 and protrusion depth D3 applicable to the front interface structure 12 also apply to the rear interface structure 21.

[0061] Furthermore, if there are multiple front interface structures 12, the number of rear interface structures 21 can be the same as the number of front interface structures 12, thereby maximizing the connection strength between the rear floor panel 2 and the front floor panel 1. Alternatively, the number of rear interface structures 21 can be less than the number of front interface structures 12. This is not a limitation in the present application.

[0062] The front interface structure 12 protrudes downward from the lower surface 111 and can be configured as a convex portion, and the upper surface 115 is configured as a flat surface at the location corresponding to the front interface structure 12. As shown in Figure 8, in some embodiments, the front interface structure 12 is formed by the upper surface 115 and the lower surface 111 jointly protruding downward to form a convex portion. In this embodiment, the thickness of the front floor body 11 along the first direction X varies uniformly, and the uniformity of strength is also improved. This configuration effectively prevents stress increases and the resulting stress fatigue at locations where the wall thickness changes suddenly, thereby effectively improving the overall strength and service life of the front floor body 11.

[0063] In addition, in the technical solution in which the front interface structure 12 protrudes downward from the lower surface 111 , the arrangement of the pipeline 6 and the yield structure 13 can refer to the description of the aforementioned related embodiments and will not be repeated here.

[0064] The following description is focused on the rear floor 2. It should be noted that all embodiments of the present application can be combined and supplemented with each other if there is no conflict.

[0065] 2 and 3 , the rear floor 2 includes a rear floor body 22 and a connecting plate 23. The rear interface structure 21 is provided on the connecting plate 23. In one embodiment, as shown in FIG2 , the rear floor body 22 and the connecting plate 23 are integrally formed. In another embodiment, as shown in FIG3 , the rear floor body 22 and the connecting plate 23 are fixedly connected. In the integrally formed embodiment, the connecting plate 23 and the rear floor body 22 form a coherent structure, thereby improving the connection stability between the connecting plate 23 and the rear floor body 22, and further improving the connection stability between the rear floor 2 and the front floor 1. In the fixed connection embodiment, the rear floor 2 can adjust the setting mode of the connecting plate 23 according to factors such as the thickness and structure of the rear floor body 22, so that the rear floor 2 can cooperate with the front floor 1.

[0066] In the embodiments shown in Figures 2 and 3, the front floor 1 is identical. In other words, the strip-shaped arrangement of the opening 121 of the front interface structure 12 of the present application effectively improves the versatility of the front interface structure 12, so that the front floor 1 can be connected to rear floors 2 of different structures through the front interface structure 12. During the production of the vehicle 100, the manufacturer can use one front floor 1 to match different rear floors 2, thereby producing a variety of different vehicle models. It can be seen that the arrangement of the front floor 1 of the present application can reduce the design cost and production cost of the vehicle 100 and improve the design efficiency and production efficiency of the vehicle 100.

[0067] As shown in FIG4 , the vehicle 100 includes a battery 3. The battery 3 is disposed on one side of the lower surface 111 of the front floor panel 1. In the embodiment shown in FIG4 , the rear floor panel body 22 and the connecting plate 23 of the rear floor panel 2 are integrally formed. In the embodiment shown in FIG5 , the connecting plate 23 is fixedly connected to the rear floor panel body 22. The connecting plate 23 includes a first portion 231, a second portion 232, and a third portion 233. The first portion 231 is connected to the front floor panel 1. The second portion 232 is fixedly connected to the rear floor panel body 22 and is spaced apart from the first portion 231 along the second direction Y. The third portion 233 connects the first portion 231 and the second portion 232, and the third portion 233 extends from the first portion 231 to the second portion 232 in a direction from the lower surface 111 to the upper surface 115. With the battery 3 as a reference, the second portion 232 is further away from the battery 3 than the first portion 231.

[0068] Comparing Figures 4 and 5 , it can be seen that the rear floor panel 22 of the embodiment shown in Figure 5 is thicker than that of the embodiment shown in Figure 4 . This arrangement of the connecting plate 23 allows the front floor panel 1 to be connected to the thicker rear floor panel 2, while maintaining the relative position between the front floor panel 1 and the battery 3. As the thickness of the rear floor panel 22 increases, the extension length of the third portion 233 can be increased, thereby further increasing the distance between the second portion 232 and the battery 3.

[0069] The provision of connecting plate 23 enables vehicle 100 to connect rear floor bodies 22 of varying specifications to the front floor 1 without changing the positions of the front floor 1 and battery 3. This allows the rear floor 2 to be replaced during production for different vehicle models without having to adapt the relative position of the front floor 1 and battery 3 or the connection interface, thus reducing production costs.

[0070] Furthermore, the connecting plate 23 includes an upper surface 234 and a lower surface 235 that are arranged opposite to each other. With the battery 3 as a reference system, the upper surface 234 of the connecting plate 23 is away from the battery 3, while the lower surface 235 of the connecting plate 23 is close to the battery 3. In some embodiments, the front floor 1 and the rear floor body 22 are both connected to the upper surface 234 of the connecting plate 23, or both are connected to the lower surface 235 of the connecting plate 23. In the embodiment shown in Figure 5, the front floor 1 is connected to the upper surface 234 of the connecting plate 23, and the rear floor body 22 is connected to the lower surface 235 of the connecting plate 23. Since the second portion 232 is farther away from the battery 3 than the first portion 231, the third portion 233 extends from the first portion 231, away from the battery 3, to the second portion 232. By connecting the rear floor body 22 to the lower surface 235 of the connecting plate 23 and connecting the front floor 1 to the upper surface 234 of the connecting plate 23, the height distance between the upper surface 115 of the front floor 1 and the second portion 232 at the upper surface 234 of the connecting plate 23 is reduced, which is beneficial to improving the flatness of one side of the upper surface 115 of the front floor 1, thereby facilitating the connection of subsequent structures such as beams, and eliminating the need to set up additional structures to compensate for the height difference.

[0071] Referring to Figure 1, the rear floor 2 includes a battery interface (not shown). The battery 3 is connected to the rear floor 2 through the battery interface. In an embodiment in which the connecting plate 23 and the rear floor body 22 are integrally formed, the rear floor 2 is referred to as a first floor. In an embodiment in which the connecting plate 23 is fixedly connected to the rear floor body 22, the rear floor 2 is referred to as a second floor. In this embodiment, the battery interfaces of the first floor and the second floor may be the same. In other words, when the battery 3 of the vehicle 100 remains unchanged, the vehicle 100 can choose to connect the first floor to the front interface structure 12 and the battery 3, or can choose to connect the second floor to the front interface structure 12 and the battery 3, without having to redesign the position and interface of the battery 3, which can effectively reduce the design cost and production cost of the vehicle 100.

[0072] Similarly, vehicle 100 includes a rear seat 4. Rear floor panel 2 includes a seat interface 24, as shown in FIG3 , through which rear seat 4 connects to rear floor panel 2. In this embodiment, the seat interface 24 of the first and second floor panels can be identical. While rear seat 4 remains unchanged in vehicle 100, vehicle 100 can choose to connect rear seat 4 to either the first or second floor panel without redesigning the interface or connection location of rear seat 4, effectively reducing design and production costs for vehicle 100.

[0073] Continuing with reference to FIG1 , vehicle 100 includes a suspension 5. Rear floor 2 includes a suspension interface (not shown). Suspension 5 is connected to rear floor 2 via the suspension interface. In this embodiment, the suspension interfaces of the first and second floor panels can be identical. While maintaining suspension 5 in vehicle 100, vehicle 100 can choose to connect suspension 5 to either the first or second floor panel without redesigning the interface and structure of suspension 5, effectively reducing design and production costs for vehicle 100.

[0074] Referring to FIG3 , vehicle 100 includes a door sill (not shown). Rear floor panel 2 includes a door sill interface 25. The door sill is connected to rear floor panel 2 via door sill interface 25. In this embodiment, the door sill interface 25 of the first and second floor panels can be identical. While the door sill of vehicle 100 remains unchanged, vehicle 100 can choose to connect the door sill to the first or second floor panel without redesigning the door sill interface and structure, effectively reducing design and production costs for vehicle 100.
