Description

BACKGROUND OF THE PRESENT DISCLOSURE Field of the present disclosure

[0001] The present disclosure relates to a floor module for a vehicle, and more particularly, to a floor module for a vehicle capable of ensuring rigidity of tiles and fixing the tiles to a vehicle floor by changing a configuration of a tile structure in a structure in which the tiles are mounted on the vehicle floor. Description of the state of the art

[0002] Recently, purpose-built vehicles (PBVs) have been introduced as modularized facilities with a simple structure that can be customized to meet various needs at a time desired by the customer. The purpose-built vehicle is an environmentally friendly, multi-purpose vehicle that can be deployed at low cost to meet the customer's business purposes and requirements. As market demand increases, there is a growing need to manufacture a small number of different types of specialty vehicles.

[0003] Meanwhile, since a vehicle is a movable device unlike a living space, a tile structure is prone to noise and impact when installed on a vehicle floor. Therefore, it is difficult to install the tile structure without modifying the vehicle. Furthermore, even if the tile structure is installed on the vehicle, significant repair costs are required if some tiles are damaged, causing great inconvenience.

[0004] In addition, it is difficult for a vehicle occupant to customize the vehicle floor by replacing a floor module for a vehicle or changing the material of the vehicle floor according to the occupant's wishes.

[0005] Accordingly, there is a need for a vehicle floor tile configuration that can be customized while maintaining the rigidity of a tile structure.

[0006] The information contained in this background of the present disclosure is provided merely to facilitate understanding of the general background of the present disclosure and should not be construed as an acknowledgment or any form of indication that this information is prior art already known to a person skilled in the art. BRIEF OVERVIEW

[0007] Various aspects of the present disclosure are directed to providing a floor module for a vehicle configured to ensure the rigidity of tiles and to fix the tiles to a vehicle floor by changing a configuration of a tile attachment structure to a structure in which the tiles are attached to the vehicle floor.

[0008] The technical problems to be solved by the present disclosure are not limited to the aforementioned technical problems, and other technical problems not mentioned above can be clearly understood by those skilled in the art to which the present disclosure relates from the following descriptions.

[0010] For example, inwardly pressed recesses may be formed in the central portions of the respective sides of the tile sections, which allow the tile sections to be released from the fastening sections by external pressure.

[0011] For example, the fixing portions and the tile portions may be staggered in the transverse direction, and the fixing portions and the tile portions may be connected in the up and down directions in a state where the fixing portions and the tile portions are staggered.

[0012] For example, the floor module may further comprise: a seat rail portion provided above the vehicle floor and configured to traverse the vehicle floor and support a vehicle seat from below, wherein the sizes of the tile portions, the fixing portions, and the mounting portions provided at a point adjacent to the seat rail portion are determined as a size of the seat rail portion.

[0013] For example, a track cover may be installed over the seat track section, and first and second opposite end sections of the track cover may be bent downward and connect to the tile sections.

[0014] For example, the tile portions and the fixing portions may each have a plurality of fitting protrusions on one side, and the fixing portions may be fixed in the transverse direction by the fitting protrusions of the tile portions when the fixing portions are connected to the tile portions in the upward and downward directions.

[0015] For example, the tile portions and the fixing portions may be spaced apart from each other at a predetermined distance (interval) in the transverse direction and connected in the upward and downward directions in a state where the tile portions and the fixing portions are sequentially aligned.

[0016] For example, the tile sections, the fixing sections and the assembly sections are designed to be separated from each other.

[0017] For example, a flange portion may extend from a side surface of the fastening portions, and the plurality of fastening portions may be connected to each other by the flange portions and aligned one after the other in the transverse direction.

[0018] For example, the flange sections may be provided symmetrically based on a center section of each of the sides of the fastening sections.

[0019] For example, a fixing hole may be formed in a central portion of the fixing portions, and the fixing portions may be fixed to the vehicle floor through the fixing hole in the upward and downward directions such that the fixing portions are fixed to the vehicle floor.

[0020] For example, a protruding portion may extend upward from the mounting portions, and the mounting portions may be fixed to the fixing portions by the protruding portion and connected to the fixing portions in the upward and downward directions when the mounting portions are connected to the fixing portions.

[0021] For example, the mounting sections may be located below each corner of the fixing sections and support the tile sections and the fixing sections from below.

[0022] According to the floor module for a vehicle of the present disclosure, it is possible to ensure the rigidity of the tiles and fix the tiles to the vehicle floor by changing the configuration of the tile fixing structure in the structure in which the tiles are fixed to the vehicle floor.

[0023] In addition, the tiles can be easily replaced and installed, which allows for customization of the tile by replacing the tile purchased from the aftermarket and makes the failure of the tile easy to cope with.

[0024] The methods and apparatus of the present disclosure have additional features and advantages that will be apparent from, or more particularly set forth in, the accompanying drawing figures included herein and the following detailed description, which together serve to explain certain principles of the present disclosure.

[0035] An exemplary embodiment of the present disclosure is provided to ensure the rigidity of tiles and to fix the tiles to a vehicle floor by changing a configuration of a tile structure to a structure in which the tiles are attached to the vehicle floor.

[0036] Fig. 1 is a view exemplifying a floor module for a vehicle according to an exemplary embodiment of the present disclosure. Fig. 1 focuses primarily on the components of the exemplary embodiment of the present disclosure. However, an actual floor module for a vehicle may, of course, include more or fewer components.

[0037] In relation to Fig. 1, the floor module for a vehicle according to the exemplary embodiment of the present disclosure may include tile portions 300, attachment portions 200, and mounting portions 100. The respective components are described with reference to Fig. 2 described. Fig. 2 is a view exemplifying the components of the floor module for a vehicle according to the exemplary embodiment of the present disclosure.

[0038] First, the tile portion 300 may be provided as a plurality of tile portions 300. The plurality of tile portions 300 may cover a vehicle floor 20 of a vehicle and be sequentially aligned by connecting them to each other in a transverse direction. The tile portions 300 may each have a square shape and be arranged at predetermined intervals to cover the vehicle floor 20. The tile portion 300 may be made of various materials such as glass, metal, plastic, and leather. In this case, a sound-absorbing layer is applied to the inner side of the tile portion 300 to optimize the noise, vibration, and harshness (NVH) performance of the vehicle. A raw fabric, a film, or the like may be applied to a surface of the tile portion 300.Furthermore, the upper surfaces of the plurality of aligned tile sections 300 are parallel to the vehicle floor 20 to provide comfort to the occupants of a PBV during travel. Edge portions of the plurality of tile sections 300 are bent downward to minimize the gaps defined by the plurality of tile sections 300 in the external appearance, thereby maximizing the soundproofing effect. Referring to FIG. Fig. 2, the fixing portion 200 may be provided at a lower portion of the tile portion 300 and connected to the tile portion 300 in their up-and-down directions. Furthermore, the mounting portion 100 may be connected to the fixing portion 200 in the up-and-down directions in a state where the tile portion 300 and the fixing portion 200 are aligned (matched) with each other.

[0039] The fixing portion 200 and the mounting portion 100 are described below.

[0040] Fig. 3 is a view exemplifying a recess formed in the tile portion 300 according to the exemplary embodiment of the present disclosure. Referring to Fig. 3, indentations may be formed in the central portions (regions K) of the respective sides of the tile portion 300, which are depressed inward. The indentation is configured so that the tile portion 300 can be separated from the attachment portion 200 when external pressure is applied to the tile portion 300. If the tile portion 300 is broken or needs to be repaired, the tile portion 300 can be easily detached using a simple tool such as a rubber spatula instead of a screwdriver.

[0041] This is done using Fig. 4 and Fig. 5 is explained in more detail.

[0042] Fig. 4 and Fig. 5 are views each showing a cross section along the line EE in Fig. 3 and a cross section along the line FF in Fig. 3. With reference to Fig. 4, in the areas K, which are the center portions of the respective sides of the tile portion 300, the plurality of tile portions 300, which are aligned one after the other, are arranged at predetermined intervals without abutting against each other. When external pressure is applied to the present portion, the tile portion 300 can be separated from the attachment portion 200. With respect to Fig. 5, in the area L, which is a region where the plurality of tile sections 300 are adjacent to each other, except for the center portions of the respective sides and the tile section 300, the tile section 300 is hardly separated from the attachment portion 200 even when external pressure is applied to the tile section 300. Therefore, the tile section 300 can be easily replaced through the area K such that the tile purchased from the aftermarket can be interchangeably attached (mounted), and the tile section 300 can be customized according to personal preferences.

[0043] Furthermore, the fixing portion 200, like the tile portion 300, may be provided as a plurality of fixing portions 200. The plurality of fixing portions 200 may be sequentially aligned by connecting them together in their transverse direction. The fixing portion 200 may be positioned between the tile portion 300 and the mounting portion 100 and fix the tile portion 300, thereby ensuring the rigidity of the tile portion 300. Furthermore, the fixing portion 200 may be fixed to the vehicle floor 20 through fixing holes 210 and robustly attached to a vehicle body.

[0044] A method for arranging the plurality of tile sections 300 and the fixing section 200 will be described in detail.

[0045] Fig. 6 and Fig. 7 are views exemplifying a state in which the tile portion 300 and the fixing portion 200 according to the exemplary embodiment of the present disclosure are arranged so as to be staggered in their transverse direction. The tile portion 300 and the fixing portion 200 can be attached to positions that match each other one-to-one. As shown in Fig. 6, however, when the tile portion 300 and the fixing portion 200 are assembled in a staggered manner, an effect of further improving the rigidity can be expected compared to the case where the tile portion 300 and the fixing portion 200 are assembled at positions that are one-to-one matched. As shown in Fig. As shown in Figure 7, the tile portion 300 and the attachment portion 200 can be assembled in a 1 / 2 offset manner. When the attachment portion 200 and the tile portion 300 are arranged to be offset in the transverse direction, when the tile portion 300 is moved by 1 / 2, the pressure caused by an external collision of the vehicle can be dispersed without being concentrated on the edge portions of the tile portion 300 and the edge portions of the attachment portion 200, thereby improving the rigidity of the tile.

[0046] Fig. Fig. 8 is a view showing, by way of example, a cross section taken along the line AA in the state in which the tile portion 300 and the fixing portion 200 are arranged offset in the transverse direction. With reference to Fig. 8, the tile portion 300 and the fixing portion 200 may each have a plurality of fitting projections 201 and 301 formed on one side thereof.

[0047] The fitting projections 301 extending downward from the tile portion 300 and the fitting projections 201 extending upward from the fixing portion 200 are firmly supported on each other in the transverse direction, so that the tile portion 300 and the fixing portion 200 are connected in the up-and-down direction.

[0048] As described above, the fixing portion 200 can be connected to the tile portion 300 in the state where the fixing portion 200 and the tile portion 300 are offset by 1 / 2 (half) a size in the transverse direction when the tile portion 300 is moved by 1 / 2. The floor module for a vehicle has been described as configured such that the tile portion 300 and the fixing portion 200 are offset by 1 / 2 a size. However, the present configuration is for illustrative purposes only, and the present disclosure is not necessarily limited to the present configuration. It will be apparent to those skilled in the art that various modifications, such as arrangement at a predetermined pitch, can be made to improve rigidity.

[0049] Fig. 9 and Fig. 10 are views exemplifying a state in which the fixing portion 200 is fixed to the vehicle floor 20 through the fixing hole 210 according to the exemplary embodiment of the present disclosure.

[0050] With reference to Fig. 9 and Fig. 10, the fastening hole 210 may be formed in a central portion of the fastening portion 200. The fastening hole 210 is provided as a plurality of fastening holes 210. During a fastening process, the fastening portion 200, the vehicle floor 20, and a body panel 10 are fastened in the up-and-down direction by screwing, thereby improving the rigidity of the tile. The plurality of tile portions 300 may be assembled in a state where the plurality of tile portions 300 are sequentially aligned. In a state where the tile portion 300 that mates with the fastening portion 200 is removed, a fastening screw 211 is inserted into a stud bolt 212 that connects the vehicle floor 20 and the body panel 10, and then the tile portions 300 are assembled.The position of the fastening screw 211 and the number of fastening screws 211 can be set differently for each vehicle.

[0051] Fig. 11 is a view exemplifying a configuration of a seat rail portion 30 according to the exemplary embodiment of the present disclosure. Fig. 12 is a view showing, by way of example, a cross section taken along the line CC in a state in which the seat rail portion 30 is in Fig. 11 is arranged.

[0052] With reference to Fig. 11, the seat rail portion 30 may be provided above the vehicle floor 20 and traverse the vehicle floor 20. The seat rail portion 30 may support a vehicle seat from below. The vehicle seat in the PBV vehicle may be supported from below by the seat rail portion 30. Furthermore, the sizes of the tile portion 300, the fixing portion 200, and the mounting portion 100 provided at a point (area S) adjacent to the seat rail portion 30 may be determined as a size of the seat rail portion 30. An entire size of the tile portion 300 needs to enter a lateral side of the seat rail portion 30, however, a space for accommodating the entire tile portion 300 is limited by the seat rail portion 30.For example, based on the existing size, the tile section 300' and the fixing section 200' can be arranged with 1 / 3 size each and the fixing section 100' with 1 / 2 size.

[0053] As in Fig. As shown in Figure 12, a rail cover 31 may be mounted over the seat rail portion 30. Two opposite end portions of the rail cover 31 are bent downward and formed to abut the tile portion 300. The rail cover 31 may cover a space interval between the tile portion 300 and the seat rail portion 30, thereby compensating for a deterioration in rigidity caused by the arrangement of the seat rail portion 30.

[0054] Fig. 13 and Fig. 14 are views illustrating exemplary flange portions 220 according to the exemplary embodiment of the present disclosure and a state in which the plurality of fixing portions 200 are coupled by fitting and aligned by the flange portions 220.

[0055] With reference to Fig. 13, the flange portions 220 may extend from the side surfaces of the center portions of the respective sides of the fastening portion 200 and be arranged symmetrically. The plurality of fastening portions 200 may be connected by fitting and sequentially aligning them in the transverse direction by the flange portions 220. Referring to Fig. 14, which shows a cross section along the line DD in Fig. 13, the flange portions 220 are connected by fitting with the other fastening portions 200 arranged sequentially on the side surfaces of the fastening portion 200 in the area H such that the rigidity of the plurality of aligned fastening portions 200 as a whole is improved.

[0056] In an exemplary embodiment of the present disclosure, the attachment portions 200 include a locking groove 215 into which the flange portions 220 engage such that the overall rigidity of the plurality of aligned attachment portions 200 is improved.

[0057] Furthermore, the mounting portion 100 may be provided as a plurality of mounting portions 100. The mounting portion 100 may be provided above the vehicle floor 20 and support the tile portion 300 and the fixing portion 200 from below. The mounting portions 100 may be positioned at a lowermost end portion of the floor module for a vehicle and are configured to fix the fixing portion 200 in the up-and-down direction and stably secure the tile portion 300.

[0058] Fig. 15 is a view exemplifying a state in which the mounting portion 100 is connected to the fixing portion 200 by protruding portions 110 according to the exemplary embodiment of the present disclosure.

[0059] As in Fig.15, the protruding portion 110 may extend upward from the mounting portion 100. When the mounting portion 100 is connected to the fixing portion 200, the protruding portion 110 is fixed to the fixing portion 200 so that the mounting portion 100 can be connected to the fixing portion 200 in the upward and downward directions. An engaging portion 230 of the fixing portion 200 is supported between the protruding portions 110 such that the transverse movement of the fixing portion 200 is restricted. The mounting portions 100 may be respectively disposed below each corner of the fixing portion 200 and support the tile portion 300 and the fixing portion 200 from below. A supporting portion 120 may be provided at a lower part of the mounting portion 100 and support the mounting portion 100 from below.Therefore, the upward and downward movements of the floor module for a vehicle can be restricted so that the floor module can be fixed to the vehicle floor 20, thereby further improving the rigidity.

[0060] Furthermore, the tile section 300, the fixing section 200, and the mounting section 100 can be provided so that they are separable from each other. Even if at least one of the plurality of tile sections 300, the plurality of fixing sections 200, and the plurality of mounting sections 100 breaks or needs to be repaired, customization is possible, and a retrofit product can be easily installed and replaced, which can significantly reduce repair and replacement costs.
