DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on embodiments of the present invention shown in the accompanying drawings.

1 to 3 show an embodiment of the present invention. FIG. 1 is an overall side view of an electric vehicle, FIG. 2 is an enlarged perspective view in two directions of FIG. 1, and FIG. It is a 3 line expanded sectional view.

As shown in FIG. 1, an electric motor M for traveling is mounted on a front portion of a body of an electric vehicle V, and the electric motor M is housed in a battery box 1 provided at a center portion of the body. It is driven by a battery. A front panel 3 and a rear panel 4 are supported on a floor panel 2 formed on the upper surface of the battery box 1.

As is apparent from FIGS. 2 and 3, side frames 5 arranged on the left and right sides of the vehicle body in the front-rear direction.
Has a box section in which the outer side frame 6 and the inner side frame 7 are welded at the upper and lower flange portions 8. The floor panel 2 has a connecting portion 9 welded to the upper surface of the side frame inner 7 of the side frame 5, an inclined portion 10 rising diagonally upward from the connecting portion 9 toward the inside of the vehicle body, and And a flat portion 11 extending horizontally. A spacer 12 made of a synthetic resin extruded material is mounted on the connection portion 9 and the upper portion of the inclined portion 10 of the floor panel 2.

The spacer 12 includes an upper wall portion 13 having a smaller inclination angle than the inclined portion 10 of the floor panel 2, and an upper wall portion 13.
An engagement groove 14 that is connected to an outer end in the left-right direction and opens downward and engages the flange 8 of the side frame 5 from above, and a lower wall 15 that is overlapped with the inclined portion 10 of the floor panel 2. A vertical wall portion 16 extending upward from the left-right outer end of the lower wall portion 15 and continuing to the lower surface of the upper wall portion 13;
3 and a fixing portion 18 connected to the left and right outer ends of the lower wall portion 15 and detachably fixed to the inclined portion 10 of the floor panel 2 by clips 17. Spacer 12
Is provided with a wire harness storage space 20 which is surrounded by the upper wall portion 13, the vertical wall portion 16 and the engagement groove 14, and has an opening 19 in a portion facing the upper surface of the connection portion 9 of the floor panel 2.

[0014] Holder 22 ... are bundled in the wire harness accommodating space a predetermined distance a wire harness 21 housed in 20, the leg portions 22 ₁ are fixed through the connecting portion 9 and the inner side frame 7 of the floor panel 2 You. Two wire harnesses 23, 24 branching from the middle of the wire harness 21 extend from the cutouts 25, 26 formed in the spacer 12 to the outside of the spacer 12, and are provided on the upper surface of the floor panel 2 in a lateral direction of the vehicle body. It is guided along the outside of the member 27.

A felt 28 is laid on the upper surface of the flat portion 11 of the floor panel 2 via a melt sheet 40 which is a vibration damping material, and a mat 29 is further overlapped on the upper surface. The outer end of the mat 29 reaching the upper part of the vertical wall 16 of the spacer 12 is formed of a synthetic resin cover 30,
It is held down by the inner ends of 1,32. As shown in FIG. 3, for example, the center cover 31 is detachably fixed near the inner end thereof to the upper surface of the spacer 12 by the hook-and-loop fastener 33, and the outer end thereof is attached to the upper surface of the side frame outer 6 via a clip 34. It is fixed detachably.

A door 35 for opening and closing the side of the vehicle body includes an outer panel 36, an inner panel 37 connected to the inside of the outer panel 36, a lining 38 connected to the inside of the inner panel 37, and an inner panel 37. And a weather strip 39 provided to abut the covers 30, 31, 32.

Since the step between the left and right side frames 5 and the floor panel 2 provided at a position higher than the left and right side frames 5 is filled with the spacers 12, the left and right side portions of the floor panel 2 have a gentle inclination. And getting on and off is improved.
In addition, since the upper surface of the connecting portion between the spacer 12 and the side frame 5 is covered with the covers 30, 31, and 32, the connecting portion becomes smooth and not only the appearance is improved, but also the getting on and off property is further improved. Further, since the wire harness 21 is stored in the wire harness storage space 20 between the spacer 12 and the side frame 5, not only can the space originally filled by the spacer 12 be used for storing the wire harness 21, The wire harness 21 can be covered with the spacer 12 to protect it from damage.

Since the spacer 12 has the opening 19 that opens to the side frame 5, the maintenance of the wire harness 21 can be easily performed by removing the spacer 12 from the side frame 5. In addition, since the engagement groove 14 of the spacer 12 is engaged with the flange portion 8 of the side frame 5, not only the displacement of the spacer 12 can be reliably prevented, but also the spacer 12 is covered by the covers 30, 31, and 32. In combination with being covered, it is possible to effectively prevent water or the like from entering the wire harness storage space 20.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above-described embodiments, and various design changes can be made.

For example, in the embodiment, the present invention is applied to an electric vehicle V
However, the present invention can also be applied to an automobile using an engine as a drive source for traveling. In this case, the space corresponding to the battery box 1 of the electric vehicle V can be used as a storage space or the like.

[0021]

As described above, according to the first aspect of the present invention, since the upper surface of the connecting portion between the side frame and the floor panel is covered with the spacer, the side frame and the floor panel can be smoothly connected. Ease of getting on and off and appearance can be improved. Further, since the wire harness is arranged in the space between the spacer and the side frame, the wiring harness can be rationally laid out by effectively utilizing the space.

According to the second aspect of the present invention,
Since the space has an opening that opens to the side frame side along the wire harness, the spacer can be removed from the side frame to easily maintain the wire harness.

According to the invention described in claim 3,
The spacer has an engagement groove that opens downward, and this engagement groove is engaged from above with the flange protruding from the upper surface of the side frame, preventing the spacer from displacing with respect to the side frame. In addition, it is possible to prevent water or the like from entering the space of the spacer.

According to the invention described in claim 4,
A cover is mounted on the upper surface of the connection portion between the side frame and the spacer, and the cover covers the engagement groove of the spacer, so that the side frame and the floor panel are connected more smoothly, and the getting on / off property and appearance are further improved. In addition, intrusion of water or the like into the space of the spacer is more reliably prevented.
