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 wire cables, evaporative pipes connected to canisters, and the like.

For example, the wire cable is inserted from the fuel tank opener lever at the front of the vehicle body to the fuel tank located at the rear of the vehicle body, such as below the trunk compartment, and the evaporative pipe is also inserted from the fuel tank to the canister. The harness is generally inserted into the lower part of the vehicle body in the longitudinal direction of the vehicle body. Therefore, conventionally, the mounting structure for such a harness was such that the harness was installed in a space surrounded by the floor panel side sill inner panel and the side sill outer panel of the side sill part (1980-1993).
Publication No. 96179).

(Problems to be Solved by the Invention) However, when inserting the harness in the longitudinal direction of the vehicle body, a problem arises in the method of inserting the harness in the cross member portion provided in the vehicle width direction on the upper surface of the floor panel. For example, in order to insert a wire cable disposed from an opener lever provided on the upper surface of a floor panel in the front part of the vehicle body into the rear part of the vehicle body along the upper surface of the floor panel, it is necessary to interrupt the cross member. However, this method of providing a harness insertion hole in the cross member and passing the wire cable therethrough is not preferable because it significantly reduces the strength of the cross member.

Furthermore, at the joint between the cross member and the side sill inner, applying deformation to the cross member or side sill inner that deteriorates the bonding condition between the two and providing an insertion means will lead to a decrease in the strength of the cross member and the lower part of the vehicle body. Undesirable.

Therefore, it is an object of the present invention to provide a mounting structure that allows a harness to be mounted in a simple manner without reducing the strength of the cross member or deteriorating the joint structure of the various parts of the vehicle body.

(Means for Solving the Problems) The automotive harness mounting structure according to the present invention is such that the end of the cross member in the vehicle width direction is joined to the vertical wall of the side sill inner, and the floor panel is joined to the lower part of the cross member. A bent portion bent toward the bottom is formed near the end portion in the vehicle width direction, and the end portion in the vehicle width direction is joined to the vertical wall of the side sill inner, and is formed between the bent portion and the cross member. The harness is inserted through a space extending in the longitudinal direction of the vehicle body.

(Effects of the invention) In the present invention, the end of the cross member connected to the upper surface of the floor panel is joined to the vertical wall of the side sill inner, and the floor panel below this joint is bent downward to form a bent part. Furthermore, by joining the end portions in the vehicle width direction to the vertical wall, a space extending in the longitudinal direction of the vehicle body can be formed at the joint portion of the end portions in the vehicle width direction of the cross member, the side sill inner, and the floor panel. Therefore, it is possible to insert the harness into this space, so when inserting the harness in the longitudinal direction of the vehicle body, there is no need to open a harness insertion hole in the cross member, which reduces the strength of the cross member. There is no.

Furthermore, as described above, since the end of the cross member is joined to the vertical wall of the side sill inner, the space can be provided and the harness can be inserted without reducing the bonding force between the cross member and the side sill inner. Therefore, it is very effective in terms of car body structure.

Further, according to such a method, it is possible to securely hold and attach the harness with a simple structure without providing any other member for attaching the harness, which is very preferable.

(Embodiment) Hereinafter, one embodiment of the harness mounting structure according to the present invention will be described using the drawings and taking a wire cable as an example.

As shown in FIG. 1, this embodiment includes a cross member 1 provided in the vehicle width direction on the bottom of the vehicle, and a vertical wall 2.
Side sill inner 2 and cross member 1 with A
A space 4 is formed at the joint portion of the toe board of the floor panel 3 which is brought into contact with the lower part of the floor panel 3, and a harness 5 is inserted into this space 4.

The end of the cross member 1 has a horizontal flange 1 welded to the side sill inner 2 as shown in FIG.
A and a vertical flange 1B are formed. This flange 1A is connected to the vertical wall 2 of the side sill inner 2.
A is welded to the horizontal portion 2B at the upper end of the cross member 1, and further, the vertical flanges 1B at both edges of the end of the cross member 1 are welded while abutting against the vertical wall 2A. At the lower part of the vertical flange 1B at the end, a cross member bent portion 1C bent upward is formed symmetrically.

Furthermore, the cross member 1 is attached to the top surface of the floor panel 3 by the flange 1D at the bottom of the cross member 1.
is fixed.

A portion of the floor panel 3 corresponding to the cross member bending portion, which is near the end in the vehicle width direction of the joint portion of the cross member 1 and the floor panel 3, is bent downward to form a bend portion 3A. An end portion 3B in the vehicle width direction of this bent portion 3A is welded to the vertical wall 2A, and the floor panel 3 and the side sill inner 2 are joined and attached.

The cross member bending portion 1C and the bending portion 3A form a space 4 having a closed cross section and having a width through which the harness 5 can be inserted, extending in the longitudinal direction of the vehicle body. That is, as shown in FIG. 3, the harness 5 connected to the opener lever 10 on the front side of the vehicle body (left side in FIG. 3) moves below the cross member 1 along the bend 3A of the floor panel 3 toward the rear of the vehicle body. It is inserted.

Further, as shown in FIG. 1, the end portions 1A and 1B of the cross member 1 are fixed to the side sill inner 2 at two locations, the horizontal portion 2B and the vertical wall 2A of the side sill inner 2.
The connection between the cross member and the cross member can withstand vertical and diagonal impacts.

In comparison, for example, if the floor bending part 3A is not formed and the bending part 1C is formed only in the cross member 2 to form a similar harness insertion space, the cross member 1 is joined to the vertical wall 2A of the side sill inner 2. In addition, since the bonded portion becomes very small, the bonding strength between the two decreases, resulting in a structure that is weak against external shocks.

Therefore, as in the structure according to the present invention, it is necessary to form a bent part 3A in the floor panel 3 so that the side sill inner 2 and the cross member 1 can be welded even in the vertical direction. It is also possible to provide a bent portion at the end portion to an extent that does not interfere with joining with the side sill inner 2.

In addition, the floor panel 3 also has a vertical wall 2 at the bottom.
Since it is joined to A, the joint state of the floor panel 3, side sill inner 2, and cross member 1 at the ends in the vehicle width direction is strengthened, and a space through which the harness is inserted is formed in a preferable state.
