Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the structure for attaching an automobile harness to a vehicle body.

(Prior Art) Automobile harnesses generally include an evaporative pipe connected to a canister, a wire cable, and the like. For example, an evaporative pipe is a pipe that sends evaporated fuel that accumulates in the upper part of the fuel tank from a fuel tank located under the floor of the rear seat or under the trunk rule to a canister equipped with activated carbon. Conventionally, this evaporative pipe has often been installed by being inserted through a space surrounded by a floor panel, a side sill inner panel, and a side sill outer panel of a side sill portion.

(Problem that the invention aims to solve) The evaporated fuel in such an evaporative pipe liquefies in the pipe when it is cooled, so if the pipe is lowered along the gas flow direction, this evaporated fuel will be removed in the lower part. The problem arises that the liquefied fuel tends to stagnate, making it difficult for gas to flow through the pipe. For this reason, the pipe must be installed horizontally or upwardly from the fuel tank to the canister.

However, as described above, since the fuel tank is installed below the floor panel, the pipe is disposed along the bottom surface of the floor panel in the longitudinal direction of the vehicle body. Therefore, it is necessary for the pipe to cross the cross member formed in the vehicle width direction on the lower surface of the floor panel. In general, when a harness such as a pipe is placed around the underside of a cross member, the harness is closer to the ground in that area, and there is a risk of damage due to stones being thrown during driving. A problem arises in that the amount of damage increases. Therefore, when installing a harness across a cross member, it is desirable to do so without having to wrap around the bottom of the cross member. A method of penetrating the cross member may be considered, but this method is not preferable because the strength of the cross member decreases due to the hole.

Therefore, the present invention provides a simple method for attaching the harness across the cross member without going around the underside of the cross member, and without reducing the strength of the cross member. The purpose of this invention is to provide a structure for attaching the harness to the harness.

(Means for Solving the Problems) Therefore, in the automobile harness mounting structure according to the present invention, a cross member having a flange portion is joined to the lower surface of a floor panel at the flange portion, and the cross member is attached to the floor panel. an upwardly projecting bead is formed extending across the member;
A harness is inserted into a space in the bead between the bead and the cross member, and is disposed across the cross member, and a holding member holds the harness inserted into the bead. The flange portion of the cross member is locked at a position facing the bead internal space.

(Effect of the invention) According to the harness mounting structure according to the invention, a bead that protrudes upward in the longitudinal direction of the vehicle body is formed on the floor panel, and a space in the bead is formed between the bead and a cross member having a flange portion. The harness is fixed in the bead across the upper surface of the cross member by inserting the harness into the cross member and locking a holding member that holds the harness at a position facing the space of the bead in the flange portion. . Therefore, the harness can be attached across the top of the cross member without going around the underside of the cross member, and in this case, there is no need to drill a through hole in the crawl member for the insertion of the harness. Therefore, the strength of the cross member is not reduced, which is very effective in terms of the structure of the vehicle body.
Further, since the holding member is locked to the cross member flange portion, there is no need to separately provide a locking member, and the harness can be securely held and attached with a simple structure.

(Embodiment) An embodiment of the harness mounting structure according to the present invention will be described below with reference to the drawings, taking an evaporative purge pipe as an example.

As shown in FIGS. 1 and 2, below the floor panel 1 of the vehicle body are cross members 2, 2 in the vehicle width direction.
A side member 3 is installed in the front-rear direction. Furthermore, a fuel tank 4 is installed below it. The cross members 2, 2 have flange portions, and are joined to the lower surface of the floor panel 1 at the flange portions.

The fuel in the fuel tank 4 turns into evaporative gas within the tank and accumulates at the top of the tank, so this evaporative gas is sent to the canister, temporarily stored in the canister, and then inhaled into the engine when the engine is started. However, an evaporative purge pipe 5 is provided as a pipe for sending this evaporated gas to the canister. This evaporative pipe 5 extends upward from the top of the fuel tank 4, and extends upward from the floor panel 1.
The bead 6 is inserted into a space in an upwardly projecting bead 6 that extends across the upper surfaces of the cross members 2, 2 in the longitudinal direction of the vehicle body, and is inserted into the above-mentioned canister.

FIG. 3 shows a cross section taken along the - line in FIG. 2.

The evaporative pipe 5 is inserted into a space in the bead 6 between the bead 6 formed by the floor panel 1 and the cross member 2 and is disposed across the top of the cross member 2. It is held fixed by. The cross member 2 is formed with positioning beads 2a, 2a for stabilizing the holding member 7 in a predetermined position. FIG. 4 shows a cross section taken along the - line in FIG. 3.

The holding member 7 supports the evaporative pipe 5 at its upper portion, and its lower portion is locked at a position facing the inner space of the bead 6 of a flange portion 2b formed at the end of the cross member 2.

The evaporative pipe 5 is fixed and inserted into the bead 6 formed on the floor panel 2 by the holding member 7 which is thus locked by the positioning bead 2a and the flange portion 2b.

Such a harness attachment structure is effective not only for attaching the above-mentioned evaporative pipe but also for attaching harnesses such as wire cables, and is particularly effective for harnesses that cannot be inserted below the cross member.
