[0003] Japanese Patent Application Laid-Open No. 2019-107919

[0004] By the way, in a vehicle (electric vehicle) in which a battery is mounted on the upper side of the floor panel as described above, for example, related devices for the battery, such as a harness and various pipes, are mounted on the front side of the vehicle of the battery. These related devices are arranged between the floor panel and the first floor carpet in the vertical direction. Therefore, in the conventional floor structure of a vehicle, for example, when performing maintenance and inspection of related devices, it is necessary to remove the first floor carpet, so improvement in workability has been desired.

[0005] The present invention has been made in view of the above conventional situation, and aims to provide a floor structure of a vehicle capable of improving the workability related to the maintenance and inspection of related devices arranged below the first floor carpet in a vehicle equipped with a battery and its related devices.

[0006] The floor structure of the vehicle according to the present invention has a structure including a battery arranged below the front seat on the upper side of the floor panel of the vehicle, a first floor carpet laid on the front side of the vehicle of the battery, and related devices for the battery arranged below the first floor carpet. And the floor structure of the above vehicle is characterized in that the first floor carpet has a cut extending from the rear edge on the vehicle side to the front side on the vehicle.

[0007] The vehicle floor structure according to the present invention, by adopting the above configuration, makes it possible to fold back a portion of the first floor carpet along the cutout, allowing the battery-related equipment to be easily identified by sight or touch, thereby improving the workability related to maintenance and inspection of the equipment.

[0008] These are a plan view (A) and a side view (B) showing a first embodiment of the vehicle's floor structure. This is a plan view illustrating the main parts of the first floor carpet. These are a plan view (A) and a side view (B) showing the configuration of the center console.

[0009] <First Embodiment> The vehicle floor structure shown in Figure 1 has a structure comprising a battery 3 positioned above the floor panel 1 and below the front seats 2, 2, a first floor carpet (front floor carpet) 4 laid on the front side of the vehicle (left side in Figure 1: arrow FR) of the battery 3, a second floor carpet (center floor carpet) 14 laid behind the first floor carpet 4 and above the battery 3, and battery-related equipment 5 positioned below the first floor carpet 4.

[0010] The floor panel 1 is a well-known metal panel and has various features such as indentations and holes for mounting various devices, but these are omitted in the drawing. In the illustrated example, the floor panel 1 has a recess 17 between the front cross member 15 and the rear cross member 16, which are arranged in the longitudinal direction of the vehicle, and the battery 3 is housed in this recess 17.

[0011] Seat rails 18 are mounted on the front and rear cross members 15 and 16 above the second floor carpet 14, and the front seats 2 are mounted to these seat rails 18 so as to be adjustable for the front and rear.

[0012] Battery 3 is the main power source for the electric vehicle, and in this case, a sub-battery (not shown) is also installed. The battery-related equipment 5 is not particularly limited, but includes, for example, harnesses, various pipes, and connectors. In addition, spacers or filling materials are provided in the gap between the upper first floor carpet 4 and the lower floor panel 1 around the related equipment 5 to prevent unevenness from occurring on the surface of the first floor carpet 4.

[0013] The first floor carpet 4 is made of a well-known material and has notches C, C extending from the rear edge of the vehicle toward the front of the vehicle and reaching above the related equipment 5 in a side view. A third floor carpet (rear floor carpet) for the rear seats, not shown in the figure, is laid on the rear side of the second floor carpet 14.

[0014] The first floor carpet 4 in the illustrated example is formed in a convex shape directed towards the rear of the vehicle when viewed from above. Specifically, the first floor carpet 4 has a central part and right and left parts on either side of it in the vehicle width direction, and has an extension 6 that extends rearward from the central part in the vehicle width direction. The extension 6 is provided behind the rear ends of the right and left parts in the vehicle longitudinal direction. The first floor carpet 4 has a notch C formed by cutting into the carpet, and the notch C has a hook shape having a first line segment C1 formed in the vehicle width direction from the edge of the extension 6 on the vehicle width direction side, and a second line segment C2 formed in the vehicle forward direction from the end of the first line segment C1.

[0015] In the illustrated example, the notches C are formed on both sides of the extension 6 in the vehicle width direction, and the lengths of the line segments C1 and C2 of the notch C on the left side of the vehicle (lower side in Figure 1A) are greater than the lengths of the line segments C1 and C2 of the notch C on the right side of the vehicle, but the relative sizes and shapes are not limited.

[0016] As a result, the extension portion 6 of the first floor carpet 4 is divided into three parts: left and right side regions Ar and Al separated by the cutouts C and C on both sides, and a central region Ac between the cutouts C and C. The central region Ac of the extension portion 6 of the first floor carpet 4 is fixed to the floor panel 1, and the left and right side regions Ar and Al are foldable.

[0017] Furthermore, as shown in Figure 2, the floor structure described above has a first piece M1 of the magic fastener M attached to the back surface of one region separated by a cut C, with the first piece M1 extending outwards toward the other region. In the illustrated example, the first piece M1 is attached to the back surface of the central region Ac, with the first piece M1 extending outwards toward the left and right side regions Ar and Al, respectively. In contrast, the second piece M2 of the magic fastener M is attached to the back surface of the other region, i.e., the left and right side regions Ar and Al.

[0018] The magic fastener M, also known as a hook-and-loop fastener, consists of one side with numerous fine loops and another side with numerous fine hooks. In this embodiment, one side is designated as the first side M1 and the other as the second side M2.

[0019] In the floor structure described above, the first piece M1 and the second piece M2 of the magic fastener M are provided on a portion of the line of the cutout C, and in the illustrated example, they are each placed in two locations. Therefore, in the cutout C, the portion where the magic fastener M is not placed is kept closed by the fastener M, but can be used as a through-hole for harnesses and piping.

[0020] Furthermore, as shown in Figure 3, the above floor structure includes a center console 7 positioned in the center of the first floor carpet 4 in the vehicle width direction, covering an area including the extension 6. The center console 7 is located in the vehicle width direction between the driver's seat and the passenger seat, which are the front seats 2. The center console 7 has an opening 8 and a lid 9 on its side that closes the opening 8. In the illustrated example, the center console 7 has openings 8 on its left and right sides that extend vertically across the center console 7, and lids 9 that open and close the openings 8. The opening 8 is positioned to overlap with the cutout C in a side view, with its rear end located behind the first line segment C1, which is the rear end of the cutout C, and its front end located in front of the foremost part of the related equipment 5.

[0021] The center console 7 in the illustrated example has an opening 8 and a lid 9 that can be attached to and removed from this opening 8, but the lid 9 may also be a lid that opens and closes the opening 8 by sliding or rotating. Specifically, it is desirable that the opening 8 be large enough for a worker's hand to freely enter.

[0022] In the vehicle floor structure having the above configuration, a notch C is provided in the first floor carpet 4, allowing a portion of the first floor carpet 4 to be folded back along the notch C, making it easy to visually or tactilely inspect the related equipment 5. Therefore, it is not necessary to remove the first floor carpet 4 when performing maintenance and inspection of the related equipment 5, thereby improving the workability related to maintenance and inspection of the related equipment 5.

[0023] Furthermore, in the above-described floor structure, a notch C consisting of a first line segment C1 and a second line segment C2 is provided in the extension 6 located in the center of the first floor carpet 4. As a result, the notch C is positioned within the center console 7 located in the center, which improves the appearance of the first floor carpet 4 and prevents the notch C from interfering with the occupants.

[0024] In the above-described floor structure, for example, if the first floor carpet 4 does not have an extension portion 6, the position of the cutout C will be further forward than in the illustrated example, making it difficult to route the harness connecting the battery 3 located above the first floor carpet 4 to equipment such as a sub-battery located in the center console 7. In contrast, the above-described floor structure provides an extension portion 6 in the first floor carpet 4 and a cutout C in this extension portion 6, so the position of the cutout C is closer to the rear of the vehicle, and as mentioned above, it can be used as a pass-through hole for the harness. This makes the harness routing work easier.

[0025] Furthermore, in the above-described floor structure, the second floor carpet 14 is laid after a period of concentrated work, such as the installation of underfloor components and the routing of harnesses for high-voltage components. However, it is difficult to install equipment such as sub-batteries after the second floor carpet 14 has been laid. In contrast, in the above-described floor structure, if only the first floor carpet 4 is laid, the cutouts C can be used as through-holes, making it easy to position installed equipment such as sub-batteries after the second floor carpet 14 has been laid.

[0026] Furthermore, in the above floor structure, the cutouts C of the first floor carpet 4 are formed on both sides in the vehicle width direction of the extension portion 6, and the extension portion 6 is divided into left and right side regions Ar and Al and a central region Ac, with the central region Ac fixed to the floor panel 1. As a result, the cutouts C are positioned close to both the left and right sides of the center console 7, making it easier to fold back the first floor carpet 4, and sound insulation can be ensured by covering it with the central region Ac.

[0027] Furthermore, in the above floor structure, since a magic fastener M is placed in the cutout C of the first floor carpet 4, the first floor carpet 4 can be easily fixed, the side regions Ar and Al can be easily folded back, and closing the cutout C can also contribute to improving the sound insulation effect.

[0028] Furthermore, in the above floor structure, the first piece M1 and the second piece M2 of the magic fastener M are placed on a part of the line of the cut C, making it easy to fix and fold the floor carpet 4, and the parts without the magic fastener M can be used as through holes for harnesses and pipes, while also maintaining the position of the harnesses and pipes well.

[0029] Furthermore, the above floor structure, by positioning a center console 7 having an opening 8 and a cover 9 in the center of the first floor carpet 4, allows the opening 8 to be used as an inspection hatch, and by positioning the opening 8 and the cover 9 across the vertical direction of the center console 7, hand space can be secured for folding back the floor carpet 4, further improving work efficiency and making it easier to check the connections of other parts.

[0030] The floor structure of the vehicle according to the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present invention.
