In order to save costs and improve efficiency, the vehicle floor assembly structure needs to be improved to improve the compatibility issues among different models developed on the same platform.

[0037] In order to solve the problems in the related prior art, the present application provides a vehicle floor, see Figures 1 to 6 , Figure 1 This is a schematic diagram of a local structure of a vehicle floor according to an embodiment of the present application from a first viewing angle. Figure 2 is a schematic structural diagram of an embodiment of a rear floor frame provided by the present application, Figure 3 yes Figure 2 The enlarged structural diagram in the dotted frame of the rear floor frame is shown in FIG. Figure 4 yes Figure 1 The vehicle floor is shown in a partial cutaway view along the dashed line CC. Figure 5 yes Figure 1 The second perspective schematic diagram of the local structure of the vehicle floor is shown, Figure 6 It is a schematic structural diagram of an embodiment of a rear wheel cover provided in the present application.

[0038] The vehicle floor 1 includes a front floor assembly 10, a rear floor assembly 20 and a spare tire well assembly 30 which are connected in sequence along the length direction of the vehicle. The rear floor assembly 20 includes a rear floor 210 and a rear floor frame 220. The rear floor 210 is carried on the rear floor frame 220. The rear floor frame 220 is respectively connected to the front floor assembly 10 and the spare tire well assembly 30. The rear floor frame 220 is provided with two wheel cover mounting portions 2230. The two wheel cover mounting portions 2230 are arranged at intervals along the width direction of the vehicle. The wheel cover mounting portion 2230 is provided with a first wheel cover mounting position 2231 and a second wheel cover mounting position 2232. The second wheel cover mounting position 2232 is closer to the inner side of the vehicle floor 1 relative to the first wheel cover mounting position 2231 in the width direction. The rear floor frame 220 installs the rear wheel cover 2 through the two first wheel cover mounting positions 2231 of the two wheel cover mounting portions 2230, or installs the rear wheel cover 2 through the two second wheel cover mounting positions 2232 of the two wheel cover mounting portions 2230.

[0039] By setting the first wheel cover mounting position 2231 and the second wheel cover mounting position 2232 on the wheel cover mounting portion 2230 on the rear floor frame 220, because the second wheel cover mounting position 2232 is closer to the inner side of the vehicle floor 1, more parts can be arranged on the vehicle floor 1, and the first wheel cover mounting position 2231 can save more space inside the vehicle, so the vehicle floor 1 can use the first wheel cover mounting position 2231 or the second wheel cover mounting position 2232 to meet the needs of different models, so the vehicle floor 1 provided by the present application has good versatility and compatibility. The rear floor frame 220 is a highly integrated one-piece structure formed by aluminum alloy die casting, and its arrangement plasticity is strong, so it can be die-cast into various shapes, so a reinforcing rib structure can be formed thereon, which can meet the lightweight requirements and stiffness requirements at the same time, and the chassis subframe mounting point and the rear suspension mounting point are integrated thereon.

[0040] The wheel cover mounting portion 2230 includes a first mounting plate 2233, a second mounting plate 2234 and a third mounting plate 2235 which are spaced apart along the width direction. The second mounting plate 2234 is located between the first mounting plate 2233 and the third mounting plate 2235. The third mounting plate 2235 is closer to the inner side of the vehicle floor 1 relative to the first mounting plate 2233. The first mounting plate 2233, the second mounting plate 2234 and the third mounting plate 2235 are all extended along the height direction of the vehicle. The first mounting plate 2233 and the second mounting plate 2234 together constitute a first wheel cover mounting position 2231, and the first mounting plate 2233 and the third mounting plate 2235 together constitute a second wheel cover mounting position 2232.

[0041] The first mounting plate 2233, the second mounting plate 2234 and the third mounting plate 2235 all extend in the length direction and the height direction of the vehicle, and the first mounting plate 2233, the second mounting plate 2234 and the third mounting plate 2235 are combined to form a mounting cavity on the wheel cover mounting portion 2230, and the mounting cavity opens toward the upper part in the height direction of the vehicle. The rear wheel cover 2 includes a wheel cover body 21 and a wheel cover reinforcement plate 22. The wheel cover mounting portion 2230 is located in the middle area of ​​the rear floor frame 220 in the length direction of the vehicle. The wheel cover body 21 is connected to the first mounting plate 2233 located at the outermost side of the vehicle by an SPR (self-piercing riveting) process, and the remaining part of the wheel cover body 21 is connected to the wheel cover mounting portion 2230 of the rear floor frame 220 by an SPR process. When the vehicle floor 1 uses the first wheel cover mounting position 2231 to mount the rear wheel cover 2, the wheel cover reinforcement plate 22 is connected to the second mounting plate 2234. When the vehicle floor 1 uses the second wheel cover mounting position 2232 to mount the rear wheel cover 2, the wheel cover reinforcement plate 22 is connected to the third mounting plate 2235. The wheel cover reinforcement plate 22 and the second mounting plate 2234 or the third mounting plate 2235 can be fixed by bolts or welding. It should be noted that the length of the mounting cavity formed by the first mounting plate 2233, the second mounting plate and the third mounting plate 2235 in the vehicle length direction is less than the length of the wheel cover mounting portion 2230. The rear floor frame 220 is recessed in the inner area in the width direction and protrudes in the upper area in the vehicle height direction to form the wheel cover mounting portion 2230, so that the wheel cover mounting portion 2230 forms a cavity for wheel mounting at the bottom of the vehicle height direction.

[0042] When the rear floor frame 220 is installed with the rear wheel house 2 through the two second wheel house mounting positions 2232 of the two wheel house mounting parts 2230, the height dimension of the second mounting plate 2234 is smaller than the height dimension of the third mounting plate 2235.

[0043] When the second wheel cover mounting position 2232 is used to install the rear wheel cover 2, the second mounting plate 2234 can be machined to ensure that the second mounting plate 2234 does not abut against the wheel cover reinforcement plate 22 in the height direction, thereby affecting the installation of the wheel cover reinforcement plate 22; similarly, when the first wheel cover mounting position 2231 is used to install the rear wheel cover 2, the third mounting plate 2235 can be machined to save space in the vehicle.

[0044] The rear floor frame 220 includes two frame longitudinal beams 221, a frame front cross beam 222 and a frame rear cross beam 223. The two frame longitudinal beams 221 are spaced apart in the width direction, and the frame front cross beam 222 and the frame rear cross beam 223 are spaced apart in the length direction. One frame longitudinal beam 221 connects the two ends of the frame front cross beam 222 and the frame rear cross beam 223 respectively, and the other frame longitudinal beam 221 connects the other ends of the frame front cross beam 222 and the frame rear cross beam 223 respectively to form a hollow frame. The rear floor 210 connects the two frame longitudinal beams 221, the frame front cross beam 222 and the frame rear cross beam 223 respectively and covers the hollow frame. A wheel cover mounting portion 2230 is installed on one frame longitudinal beam 221.

[0045] The two longitudinal beams 221 extend forward and backward in the length direction of the vehicle, the front cross beam 222 and the rear cross beam 223 extend in the width direction of the vehicle and are connected to the two longitudinal beams 221, the rear cross beam 223 is close to the tail of the vehicle in the length direction, and the rear cross beam 223 is an overall "J"-shaped structure. The front cross beam 222 and the rear cross beam 223 have a cavity structure to improve the torsional rigidity of the rear floor frame 220. The front cross beam cavity of the front cross beam 222 opens toward the upper part in the height direction of the vehicle, and the front cross beam 223 is provided with a cavity structure to improve the torsional rigidity of the rear floor frame 220. A front cross beam flange is provided on the opening side of the cross beam cavity, the rear cross beam cavity opening of the frame rear cross beam 223 faces the bottom in the height direction of the vehicle, and a rear cross beam flange is provided on the opening side of the rear cross beam cavity. One end of the rear floor 210 covers and is connected to the front cross beam flange on one side of the front cross beam cavity opening of the frame front cross beam 222, thereby sealing the front cross beam cavity opening of the frame front cross beam 222, and the other end of the rear floor 210 is connected to the rear cross beam flange. The rear floor 210 and the rear floor frame 220 are connected by the SPR process and covered on the hollow frame.

[0046] See also Figure 2 , Figure 2 It is a schematic structural diagram of an embodiment of a rear floor frame provided in the present application.

[0047] In the length direction, the connection point of the skeleton front cross beam 222 and the two skeleton longitudinal beams 221 is spaced apart from one end of the two skeleton longitudinal beams 221 to form a first connection portion 2210 at one end of the two skeleton longitudinal beams 221, and the connection point of the skeleton rear cross beam 223 and the two skeleton longitudinal beams 221 is spaced apart from the other end of the two skeleton longitudinal beams 221 to form a second connection portion 2220 at the other end of the two skeleton longitudinal beams 221, the first connection portion 2210 and the skeleton front cross beam 222 close to the first connection portion 2210 are jointly connected to the front floor assembly 10, and the second connection portion 2220 and the skeleton rear cross beam 223 close to the second connection portion 2220 are jointly connected to the spare tire groove assembly 30.

[0048] One end of the two frame longitudinal beams 221 in the vehicle length direction extends from the frame front cross beam 222 to form a first connection portion 2210. The first connection portion 2210 and the frame front cross beam 222 together form a U-shaped structure. The opening of the U-shaped structure faces the front floor assembly 10. The other end of the two frame longitudinal beams 221 in the vehicle length direction extends from the frame rear cross beam 223 to form a second connection portion 2220. The second connection portion 2220 is an overall "J"-shaped structure. The second connection portion 2220 and the frame rear cross beam 223 together form a U-shaped structure. The opening of the U-shaped structure faces the spare tire slot assembly 30. The rear floor frame 220 is an overall butterfly shape.

The first connecting portion 2210 is connected to the sill beam 110, the front floor 120 and the lifting plate 130. The skeleton front cross beam 222 is connected to the front floor 120 and the lifting plate 130.

[0051] The first connection part 2210 is in an L-shaped structure, so that flanges are formed in different directions, thereby increasing the connection area between the threshold beam 110 and the first connection part 2210 and increasing the torsional stiffness of the rear floor frame 220. The first connection part 2210 is horizontally transitionally connected to the inner side of the threshold beam 110. The first connection part 2210 and the threshold beam 110 can be connected from the inner side to the outer side of the front floor 120 by bolts. Correspondingly, bolt holes are provided on the threshold beam 110 and the first connection part 2210. The front floor 120 is overlapped on one side of the front beam cavity opening of the frame front beam 222. The lifting plate 130 is connected to the side of the frame front beam 222 away from the front beam cavity opening. The lifting plate 130 is used to lift CTC (cell chassis integration) cells.

The rear floor crossbeam 230 is connected to the frame longitudinal beam 221 via the crossbeam boss 2236.

[0053] In the length direction, a triangular positioning protrusion 2237 is formed on the top of the skeleton longitudinal beam 221 in the middle area of ​​the hollow frame, and the crossbeam boss 2236 is correspondingly arranged at the position adjacent to the first wheel cover mounting position 2231 and the second mounting position in the width direction. A plurality of oblique reinforcing ribs are also arranged at the position adjacent to the crossbeam boss 2236 on the wheel cover mounting portion 2230, so as to increase the strength of the wheel cover mounting portion 2230. The positioning protrusion 2237 and the crossbeam boss 2236 facilitate positioning when installing the rear floor crossbeam 230. The rear floor 210 presents an L-shaped structure, and the rear floor 210 includes a rear section of the rear floor extending in the length direction and a front section of the rear floor extending in the height direction. The front section of the rear floor and the rear section of the rear floor are bent and connected, so that the shape of the rear floor 210 is adapted to the positioning protrusion 2237, and the rear floor 210 overlaps the positioning protrusion 2237.
