Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire harness mounting structure for an automobile, which is intended for accurate positioning and improvement of mounting workability of a wire harness disposed along a tire house.

As shown in FIG. 1 showing the appearance of a general passenger car, the automobile 1 is equipped with various electrical components and various sensors (not shown) for realizing smooth operation of an engine, all of which are installed in an engine room. It is electrically connected to a battery, an electronic control device, and the like (not shown) provided in the unit 2 via a wire harness.

For this reason, various means have been devised for wiring or fixing the wire harness at various places on the vehicle body panel, and in the production line of the automobile 1, it is necessary to ensure the positioning and workability of this wire harness with respect to the vehicle body panel. Is
It is a very important issue.

For example, FIG. 2 showing a sectional structure taken along the line AA in FIG.
As shown in (a), the wire harness is also arranged in the front tire house. That is, the wire harnesses 4 and 4 ′ are wired in the upper frame 3 having a tubular cross-sectional structure by the outer frame panel 3 a and the inner frame panel 3 b, or the splash shield 6 to which the lower surface of the upper frame 3 is attached. It is wired to the fender panel 5 side of the upper surface. In the figure, reference numeral 7 is a strut housing, and 9 is a front wheel.

However, in the conventional wiring structure of the wire harness 4, 4'shown in FIG. 2 (a), the upper frame 3
Combined with the fact that the wire harness 4, 4'cannot be positioned very accurately with respect to the vehicle body panel such as the splash shield 6 and the splash shield 6, in particular, in the type in which the wire harness 4, 4'is wired in the upper frame 3, It has been pointed out that the workability of attaching the wire harnesses 4 and 4'on the production line is extremely poor.

The present invention eliminates the conventional inconveniences associated with wiring of a wire harness in a tire house and enables accurate positioning with respect to a vehicle body panel, thereby improving the workability of installing a wire harness in a vehicle production line. An object is to provide a wire harness mounting structure.

A wire harness mounting structure for an automobile according to the present invention that can achieve this object includes an upper frame having a tubular cross-section structure in which flange portions of a plurality of frame panels extending in the front-rear direction of a vehicle body along a tire house are joined to each other. , In an automobile having a splash shield in which the lower surface of the upper frame is attached to the upper surface, one flange portion of the frame panel is arranged above the splash shield with a gap substantially parallel to the upper surface of the splash shield, It is characterized in that a groove-shaped harness holding portion capable of sandwiching a wire harness is formed by the flange portion, the upper frame and the upper surface of the splash shield.

Based on the embodiment shown in the drawings, an embodiment of a wire harness mounting structure for an automobile according to the present invention will be described in detail with reference to FIG. 2 (b) similar to FIG. 2 (a). To do. It should be noted that the same members as the conventional members are denoted by the same reference numerals.

The upper frame 3 of this embodiment, which is attached to the upper surface of the splash shield 6 that constitutes the tire house 12, has a tubular cross-sectional structure composed of an outer frame panel 3a, an inner frame panel 3b, and a lower frame panel 3c. The flange portion 3a 'of the upper frame panel 3a and the flange portion 3c' of the lower frame panel 3c, which are located on the fender 5 side, are arranged above the splash shield 6 with a gap substantially parallel to the upper surface. Has been done. These flange portions 3a 'and 3c', the side surfaces of the lower frame panel 3c and the splash shield 6
A groove-like harness holding portion 10 is formed by the upper surface of the wire harness 4, and the wire harness 4 is inserted into the harness holding portion 10.

Therefore, the wire harness 4 is securely sandwiched by the groove-shaped harness holding portion 10, and the design length of the wire harness 4 wired in the wheel house 12 can be accurately determined.

In order to prevent the wire harness 4 from falling off from the harness holding portion 10 due to vibration of the vehicle body or the like, the upper surface of the splash shield 6 and the flange portions 3a ', 3c' relative to the outer diameter of the wire harness 4 are prevented. It suffices to set a proper interference fit between the wire harness 4 and the above, but it is also possible to securely fix the wire harness 4 to the upper frame 3 by using the clip 11 inserted into the upper frame 3.

As described above, according to the automobile wire harness mounting structure of the present invention, the flange portions of the plurality of frame panels constituting the upper frame are used, and the wire harness is formed by the flange portions, the upper frame and the upper surface of the splash shield. Since the groove-shaped harness holding part that can be held is formed, the wiring of the wire harness can be performed without forming the upper frame or the splash shield into a special shape for holding the wire harness or providing new parts or members. Space for use can be secured. Further, since the harness holding portion has the groove-shaped cross section, it is possible to improve the rigidity of the vehicle body, and at the same time, it is possible to attempt the accurate positioning of the wire harness and the improvement of the mounting workability.
