Here, in an upper angular part of the floor tunnel 3 and upper angular parts 10, 10 of the cross member 5, recessed parts 8, 11 hollowed toward the downward are provided, the wire harness 1 is mounted in the recessed parts 8, 11 to be arranged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle floor structure. More specifically, the present invention relates to the shape of a floor panel when wiring a wire harness in an automobile.

[0002]

2. Description of the Related Art Normally, in a wire harness, in a vehicle such as an automobile, electric wires are bundled in advance according to a mounting shape and a connecting terminal is installed at a terminal. 5 to 8 show a state in which the wire harness is installed on the floor panel.

FIG. 5 shows a wiring harness b on a floor panel a.
FIG. 6 is a perspective view showing a state in which the cables are installed, and FIG. 6 is VI-VI of FIG.
It is a longitudinal cross-sectional view by a line. Normally, a floor tunnel c extends in the vehicle front-rear direction at the center of the floor panel a. Further, side panels d are provided on both left and right sides of the vehicle, and cross members e are provided between the side panels d in the vehicle width direction. As can be seen from this figure, a wire harness b is generally installed on the upper surface of the floor tunnel c and the side surface of the cross member e, and is fixed to a suitable portion with a tape f or a clamp.

FIG. 7 is a perspective view showing a state in which the wire harness b is routed under the side surface of the floor tunnel c, and FIG.
FIG. 8 is a vertical sectional view taken along the line VIII-VIII in FIG. 7.
Similar to the case of FIG. 5, the wire harness b is fixed to an appropriate portion with the tape f or the clamp.

[0005]

However, the conventional vehicle floor structure described above has the following problems. (1) When the floor carpet g was laid on the floor panel a, a part of the floor carpet g formed a protrusion by the wire harness b, impairing the appearance. (2) When the convex portion of the floor carpet g is stepped on, there is a lumpy feeling and it is uncomfortable. (3) The wiring route of the wire harness b is not clear, and a wiring position defect may occur. In this case, there is a possibility that the wire harness b may be broken when the seat is moved and the wire may be broken.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a floor panel having no convex portion when a wire harness is installed.

[0007]

The present invention has been made to solve the above-mentioned object, and its gist is to provide a floor tunnel extending in the vehicle front-rear direction and having a substantially U-shaped cross section.
With cross members arranged in the vehicle width direction of the floor panel,
In a floor structure of a vehicle constituted by the floor tunnel and a wire harness arranged along the cross member, in the upper corner portion of the floor tunnel and the upper corner portion of the cross member, a recessed concave portion is formed downward. That is, the wire harness is placed and wired in the recess.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The floor structure of a vehicle according to the present invention will be described in detail below with reference to the drawings. FIG.
It is a perspective view which shows the floor panel 2 which wired the wire harness 1. A floor tunnel 3 extends through the center of the floor panel 2 in the vehicle front-rear direction. Further, side panels 4 are arranged on both left and right sides of the vehicle, and cross members 5 are provided in the vehicle width direction so as to connect the side panels 4. Each of the floor tunnel 3 and the cross member 5 has a substantially U-shaped cross section, and a concave portion that is recessed downward is provided at each upper surface corner portion. The wire harness 1 is placed in the recess and is routed using a tape 6 or the like. This installation state will be described with reference to FIGS.

FIG. 2 is a vertical sectional view taken along line II-II of FIG. 2 above the floor tunnel 3 with a generally U-shaped cross section
It has corners 7, 7 at some points, and one of the corners 7, 7 is provided with a recess 8 which is recessed downward. The depth D of the recess 8 is preferably determined according to the diameter of the wire harness 1. That is, it is preferable that after the wire harness 1 is placed, the floor carpet 9 is laid on the floor panel 2 so that no protrusion is formed on the floor carpet 9.

FIG. 3 is a vertical sectional view taken along line III-III of FIG. 1, and FIG. 4 is a vertical sectional view taken along line IV-IV of FIG. Similar to the case of the floor tunnel 3, two corners 10 and 1 are provided above the cross member 5 having a substantially U-shaped cross section.
0, and one of the corners 10, 10 is provided with a recessed portion 11 which is recessed downward.

Other Embodiments As described above, the portion where the wire harness 1 is routed is not limited to the left corner of the floor tunnel 3 and the rear corner of the cross member 5. That is, the right corner of the floor tunnel 3 and the front corner of the cross member 5 may be used.

[0012]

As described above, according to the floor structure for a vehicle of the present invention, (1) the wire harness is placed in the recesses of the floor tunnel and the cross member for wiring. For this reason, the floor carpet has no convex portion, and the appearance is improved. (2) Since the convex portion of the floor carpet is eliminated, there is no rugged feeling when stepping on the floor carpet. (3) The risk of wire harness disconnection due to movement of the seat is eliminated. (4) Since the wire harness is installed at a position higher than the bottom surface of the floor panel, there is no fear of electric leakage even if the floor gets wet.
