Hereinafter, specific embodiments of the present invention will be described with reference to the attached drawings.

1 is a perspective view schematically showing a state in which a vehicle floor structure according to an embodiment of the present invention is installed on a vehicle body, and FIGS. 2 and 3 are a perspective view and an separated perspective view schematically showing the vehicle floor structure, and FIG. Figures 4 and 5 are schematic drawings showing the bracket assembly and tile assembly extracted from the vehicle floor structure, and Figure 6 is a cross-sectional view schematically showing the section A-A of Figure 2. In addition, FIGS. 7 and 8 are diagrams sequentially showing the state in which the vehicle floor structure is installed on the vehicle body according to an embodiment of the present invention, and FIGS. 9 and 10 schematically show various embodiments of the tile assembly. This is a drawing shown.

Referring to FIGS. 1 to 10, the vehicle floor structure 100 according to an embodiment of the present invention is provided with a bracket assembly 200 installed on the vehicle body 10 and a plurality of brackets and is fastened to the bracket assembly 200. It includes a tile assembly 300 that forms the floor of the vehicle.

Recently, as electric vehicles continue to develop, the interior design of vehicles is changing. In particular, there is a trend to make the floor of vehicles flat. Accordingly, in the present invention, the plurality of bracket assemblies 200 are primarily installed on the vehicle body 10, and the plurality of tile assemblies 300 are installed on the bracket assemblies 200 to flatten the floor of the vehicle. can be formed. At this time, by manufacturing the tile assembly 300 to have various colors and shapes, the floor design can be selected according to the user's choice, thereby improving the aesthetics of the vehicle interior.

To this end, the bracket assembly 200 includes a bracket portion 210 in the form of a grid in which a plurality of unit cells 211 having hollow centers are recessed and formed between the bracket portion 210 and the vehicle body 10. It may include a base plate 220 that is disposed and made of sound-absorbing material to block sound.

That is, the bracket portion 210 is formed with a plurality of unit cells 211 continuous in the horizontal and vertical directions. In this way, the bracket portion 210 is formed of a plurality of unit cells 211 having a hollow, and the unit cells 211 are filled with air, so it is possible to block the flow of noise and heat, thereby providing noise blocking and heat insulation performance. can be further improved.

In addition, the bracket portion 210 is formed so that the unit cells 211 are partitioned from each other with a partition wall, but this is not limited to this, and although not shown in the drawing, the bracket part 210 is attached to the partition wall so that a plurality of unit cells can communicate with each other. A through hole (not shown) may be formed. In this case, space utilization can be improved by installing the electric wires installed in the vehicle in unit cells that communicate with each other through the through holes.

The bracket portion 210 is formed in the unit cell 211 disposed at the corner and the center, and includes a bolt through hole 212 through which a bolt 11 protruding outward from the vehicle body 10 is inserted, and the unit. A tile fastening groove 213 formed at a corner along the circumference of the cell 211 and into which the fastening part 320 of the tile assembly 300 is inserted and fastened, and a tile fastening groove 213 along the circumference of the bolt through hole 212. It may include an insertion protrusion 214 protruding toward the base plate 220.

The bracket portion 210 may be configured such that the bolt through hole 212 is formed only in the unit cells disposed at the corners and the center among the plurality of unit cells 211. This means that if bolt through-holes are formed in all unit cells, it may be difficult to accurately insert all bolt through-holes into the plurality of bolts 11 provided in the vehicle body 10 due to processing errors, which may lead to difficulties in assembly. Accordingly, the bolt through hole 212 is formed only in the unit cells disposed at the corners and the center, thereby improving assembly efficiency and securing the fastening force of the bracket portion 210.

Of course, the position where the bolt through hole is formed may vary depending on the number of unit cells formed in the bracket portion 210. That is, when the number of unit cells is reduced, bolt through holes may be formed in all unit cells. Conversely, when the number of unit cells increases, additional bolt through holes may be formed in the middle in addition to the unit cells arranged at the corners and the center.

The tile fastening groove 213 is a groove for fastening the tile assembly 300 to the bracket portion 210. The tile fastening groove 213 may be formed at a corner along the perimeter of the unit cell 211.

At this time, one tile assembly can be fastened to one unit cell. Of course, if the shape and size of the unit cell 211 and the tile assembly 300 are the same, one tile assembly 300 can be fastened to one unit cell 211, but the tile assembly is not limited thereto. The tile assembly 300 can be assembled even when the shape or size of the assembly 300 is different from that of the unit cell 211.

The base plate 220 includes a base plate body 221 and a bracket insertion hole 222 formed through the base plate body 221 so that the insertion protrusion 214 of the bracket portion 210 is inserted. .

The base plate body 221 is made of sound absorbing material to block sound. That is, since the base plate body 221 is located on the upper part of the vehicle body 10, it can block external noise transmitted from the bottom of the vehicle body 10 from being transmitted to the interior of the vehicle.

Additionally, the base plate body 221 may be manufactured including an insulating material that can block not only noise but also heat transfer. Through this, it is possible to insulate the temperature inside the vehicle and maintain a comfortable temperature inside the vehicle regardless of the temperature outside the vehicle.

The bracket insertion holes 222 are formed in the same number as the insertion protrusions 214 at positions corresponding to the positions where the insertion protrusions 214 formed in the bracket portion 210 are inserted. .

That is, since the base plate body 221 is made of a material with relatively lower rigidity than the bracket portion 210, the bracket insertion hole 222 is used to directly fasten the bracket portion 210 to the vehicle body 10. ) can be formed.

In addition, the base plate body 221 may be provided with a fusion point 223 indicating a position for attaching the base plate 220 to the bracket portion 210.

That is, the tile body 310 can be manufactured in various shapes.

With this configuration, the tile body 310 can form the floor of a vehicle with various designs by combining tile assemblies of different sizes as shown in FIG. 9 and in different shapes as shown in FIG. 10.

In addition, the skin layer 330 is laminated on the tile body 310 to form the floor of the vehicle. The skin layer 330 can be made of various materials and colors, such as wood, metal, reinforced resin film, and carbon fiber. That is, the skin layer 330 may be provided in various forms, such as various materials, various colors, and specific patterns, depending on the user's selection.

In addition, the vehicle floor structure 100 according to an embodiment of the present invention further includes a center sealing member 410 and a side sealing member 420 to seal between the tile assembly 300 and the bracket portion 210. It can be done. That is, the center sealing member 410 and the side sealing member 420 are made of elastic materials such as rubber for sealing.

The central sealing member 410 is inserted into the sealing member insertion groove 215 formed between the unit cells 211 of the bracket portion 210 at its lower side, and the tile assembly 300 at its upper side. is seated and configured to seal between the bracket portion 210 and the tile assembly 300.

As shown in FIG. 3, the central sealing member 410 may be formed in a grid shape to be located between the unit cells 211.

The lower side of the side sealing member 420 is inserted into a groove formed between the bracket portion 210 and the neighboring bracket portion 210, and the tile assembly 300 is seated on the upper side, thereby forming the bracket portion 210. It is configured to seal between the bracket part 210 and between the bracket part 210 and the tile assembly 300.

As shown in FIG. 3, the central sealing member 410 may be formed in a straight shape to be located between the bracket portions 210 and the bracket portion 210.
