Description

[Detailed Description of the Invention] This invention relates to a wiring structure for a rear harness in a freight vehicle.

Conventionally, when wiring a rear harness that connects the wiring for the rear combination lamp, rear license lamp, etc. in a freight vehicle, the harness 1 is connected to the side frame 2 of the vehicle body, as shown in Figures 1 and 2. The wires were attached along the inner surface using appropriate clamps (not shown) and wired.

However, since the cross member 3 is fitted into and connected to the side frame 2, such a wiring structure requires time and effort to insert the wiring between the inner surface of the side frame 2 and the end of the cross member 3, and also causes damage to the vehicle body. The harness 1 may come into contact with the sharp edges of the cross member 3 due to vibrations, etc., and the harness 1 may be damaged. (not shown). Furthermore, in addition to the harness 1, parts such as the brake tube, fuel pipe, and meter cable are also installed inside the side frame 2, so the installation work is time-consuming and difficult when installing a large number of clamp materials. It was crowded and hot.

Therefore, in consideration of the above-mentioned drawbacks of the conventional wiring structure of the rear harness, the present invention aims to improve it by covering almost the entire area under the cargo bed with a covering material having a predetermined rigidity and attaching it to the underside of the cross sill of the cargo bed, thereby simplifying the wiring work.

The configuration of the present invention will be described below with reference to embodiments shown in the drawings.

As shown in FIGS. 3 and 4, in the present invention, a loading platform 8 is supported by a cross member 3 via a mount rubber 9, and cross sills are arranged at appropriate intervals in the vehicle width direction to reinforce the loading platform 8. 10 bottom side 1
The present invention is characterized in that a rear harness 11 is attached to the lower surface 10a of the cross sill via a clamp 12, paying attention to the fact that a predetermined distance 1 exists between the side frame 2 and the cross member 3. As shown in FIG. 5, the rear harness 11 is covered with a covering member 13 extruded from, for example, soft PVC, which has a predetermined rigidity and covers substantially the entire area under the cargo platform. This is because when the rear harness 11 is directly attached to the cross sill lower surface 10a, the dimensions of the rear harness 11 take thermal expansion and contraction into account and have a margin for wiring, and the clamp 12 restrains the rear harness 11 in the front-rear direction. This is to prevent the rear harness 11 from hanging down between the cross sills 10 and 10. If the covering member 13 is a spiral tube having slots or overlapping slots, the covering work will be easier.

By wiring the rear harness 11 to the lower surface 10a of the cross sill in this way, the troublesome insertion work for wiring as in the conventional method is eliminated, and all parts of the rear combination lamp 5, rear license lamp 6, and rear harness 11 can be removed from the load. Since it will be located on the box side, the rear harness 11 can be wired during the assembly process of the cargo box where the rear combination lamp 5 and rear license lamp 6 are attached, so the connections with each lamp 5 and 6 can be made in the same process. This becomes possible.

Furthermore, there are few other parts to be attached under the spacious loading platform, and by appropriately dividing the covering member 13, there is a large degree of freedom in terms of wiring. Also, the covering member 13
Since the rear harness 11 does not hang down, it does not interfere with the appearance or the assembly or repair under the cargo platform. Further, since wiring can be done without sagging using only the number of cross sills 10, the number of clamps 12 and the work for attaching them can be reduced.

In short, in the case of the present invention, the rear harness is covered over almost the entire area under the loading platform with a covering member having a predetermined rigidity, and is attached to the underside of the cross sill of the loading platform, which improves workability, increases the degree of freedom in wiring the rear harness, and improves the wiring of the rear harness. It is possible to create an excellent wiring structure, which improves the appearance by preventing the wires from sagging, and reduces costs by reducing the number of clamps and the work required to install them.
