Description

  The present invention relates to a wiring structure of a wire harness, and more particularly to a wiring structure of a wire harness in a side sill portion (rocker portion) on a side portion of a vehicle floor of an automobile.

Conventionally, a wire harness is routed in a space between a vehicle body panel and a scuff plate placed on the vehicle body panel on a side sill portion on the side of a vehicle floor of an automobile.
For example, Japanese Utility Model Laid-Open No. 4-26836 (Patent Document 1) provides a structure shown in FIG. In this structure, the wire harness W / H, which is fixed to the clamp 1 by the tape T, is routed on the side sill 2 (rocker panel) which is a vehicle body panel and clamped, and the floor carpet 3 is attached to the wire harness W / H. A cover 4 attached with an adhesive or the like is covered, and a scuff plate 5 is further covered, and the scuff plate 5 is screwed to the side sill 2. With such a structure, the wire harness W / H is routed in the space between the side sill 2 and the scuff plate 5.

However, in the structure provided in Patent Document 1, since the wire harness W / H is taped and fixed to the clamp 1, the wire harness W / H has a circular cross-section, and is between the side sill 2 and the scuff plate 5. There is a problem that a useless gap in which the wire harness W / H is not routed is generated, and the space between the side sill 2 and the scuff plate 5 cannot be effectively used. On the other hand, the number of wires in a wire harness in recent years has increased, and it has become necessary to route the wire harness that cannot be routed in the space between the side sill 2 and the scuff plate 5 to provide another path. There is a problem that a space is required and the cost of the wire harness protective material, stoppers, and wiring work increases due to the provision of another route, which increases costs.

  In addition, since the wire harness is directly routed on the upper surface of the vehicle body panel made of the side sill 2, if the burr or the like is generated on the vehicle body panel, the wire harness may be damaged. Further, the upper surface of the wire harness W / H on the scuff plate side is covered and protected by the cover 4, and the floor carpet 3 is fixed to the upper surface side of the cover 4 with an adhesive, and is disposed on the upper surface side of the floor carpet 3. Since the scuff plate 5 is covered, the dimension between the side sill 2 and the scuff plate 5 becomes large, and the protruding amount of the scuff plate 5 becomes large.

Further, the wire harness W / H is taped around the clamp 1, and the clamp 1 is fixed to the side sill 2 with the vehicle body locking portion 1 a, while the scuff plate 5 is also fixed to the side sill 2 with the fastener 6. Since the fixing portion to the side sill 2 extends to a plurality of places, such as fixing to the side sill 2 with the locking portion 4a, there is a problem that the mounting work is troublesome. In addition, it is necessary to fix the edge of the floor carpet 3 to the cover 4 with an adhesive in advance, which causes a problem that the number of processes is extremely increased and the production efficiency is deteriorated.
Furthermore, when the wire harness W / H that has only been bound with tape is routed along the upper surface of the side sill 2, the wire harness W / H has no waist and is easy to bend, making it difficult to route and poor workability. There is also a problem.
Japanese Utility Model Publication No. 4-26836

  The present invention has been made in view of the above problems, and can be efficiently routed even if the number of wire harnesses to be routed in the space between the vehicle body panel and the scuff plate is increased. The problem is to improve the workability of assembly by reducing the number of fixing points.

In order to solve the above problems, the present invention is a wiring structure of a wire harness that is routed in a space between a body panel of an automobile and a scuff plate that covers the body panel.
A box-shaped protector for inserting the wire harness is accommodated in the space, and the bottom wall of the protector is clamped by the vehicle body panel, and both side walls in the width direction of the protector engage the both side walls of the scuff plate. Fixed and
The protector made of a resin molded product is a double door opening / closing lid whose upper or lower wall is divided at the center, and the wire group constituting the wire harness is inserted into the hollow part of the protector without being bound by tape. A wiring harness wiring structure characterized by being configured to be closed in a closed state is provided.

As described above, in the present invention, the wire harness that is routed in the space between the vehicle body panel and the scuff plate is inserted and routed in the hollow portion of the closed cross-section of the substantially box-shaped protector. It is not necessary to wind and bind the tapes, and they can be inserted into the protector one by one. Therefore, if the protector is set to the maximum size that can be arranged in the space between the vehicle body panel and the scuff plate, even if the number of wires of the wire harness is increased, the protector is routed in the path between the scuff plate and the vehicle body panel. be able to. Therefore, it is not necessary to provide a separate routing route, and the wire harness protective material, stoppers, and routing work required for the separate route are not required, and the cost can be reduced.
In particular, since the protector uses the upper or bottom wall as a double door opening / closing lid, when the upper wall is used as an opening / closing lid, the wire group constituting the wire harness is formed on the upper surface of the hollow portion surrounded by the bottom wall and the side wall. Easy to insert apart from the opening. Similarly, when the bottom wall is an opening / closing lid, if the bottom wall side is disposed on the upper surface side by turning upside down, it becomes easy to insert the electric wire group from the upper surface opening. And, normally, the electric wire is thrown into the hollow part in a mountain shape, but when closing the double doors when closing, the electric wire is distributed to both sides, and the electric wire is moved downward at the center. Therefore, the entire hollow portion of the protector can be filled with a gap without any gap, and the capacity of the protector to accommodate the wire can be increased.
Locking portions that lock each other are provided at the ends of the opening and closing lids on both sides that form the double door opening, and the closed state is maintained after filling the wires.

Further, in the present invention, since the locking portion provided on the protector is locked with the locked portion provided on the scuff plate and the scuff plate is locked and fixed to the protector, the protector itself is clamped to the vehicle body panel. This eliminates the need to screw the scuff plate to the vehicle body panel. As a result, in Patent Document 1, the number of places fixed to the vehicle body panel can be reduced to one place, and the one-touch operation for locking the clamp to the vehicle body can be performed. Can be greatly improved.
Moreover, since the scuff plate is locked and fixed on both sides of the protector, the scuff plate can be fixed to the protector in a more stable state.

When the upper wall of the protector is used as an opening / closing lid, the scuff plate is disposed in contact with the inner surface of the upper wall of the scuff plate, and is disposed over substantially the entire length of the scuff plate, while the bottom wall of the protector has a space between the scuff plate and the space. It is preferable that they are arranged along the upper surface of the vehicle body panel facing each other.
Similarly, when the lower wall of the protector is used as an opening / closing lid, the bottom wall serving as the opening / closing lid is disposed along the upper surface of the vehicle body panel, while the upper wall faces the vehicle body panel with a space therebetween. The scuff plate is disposed in contact with the inner surface of the upper wall of the scuff plate, and is disposed over substantially the entire length of the scuff plate.

In other words, the protector can be disposed so as to occupy the space between the vehicle body panel and the scuff plate, and the volume of the hollow portion of the protector that accommodates the wire harness can be increased, so that the number of wires in the wire harness can be increased. . And by arranging it over the almost entire length of the space between the scuff plate and the vehicle body panel, the wire harness routed between them can be completely protected, and the wire harness can be inserted into a rigid protector made of resin molded product Therefore, the wiring harness can be easily routed and the routing workability can be improved.
The clamp that fixes the protector to the vehicle body panel may be formed integrally with the protector, or may be provided separately and locked to the protector. It is preferable that the installation position of the clamp with respect to the protector is provided with an interval of 200 to 280 mm in the length direction.

  An end edge of the floor carpet is located in a space between the vehicle body panel and the scuff plate and at an outer position of the protector, and a fixing member for fixing the end edge is provided integrally with the protector or the clamp. Preferably it is.

  With the above configuration, the fixing of the floor carpet was fixed to the cover with an adhesive in Patent Document 1, but in the present invention, it is provided integrally with the protector or a separate clamp attached to the protector, The step of fixing the floor carpet with an adhesive can be omitted, and the floor carpet can be mechanically firmly fixed to the vehicle body at the same time when the protector is clamped to the vehicle body.

Specifically, the floor carpet extending in the space between the vehicle body panel and the scuff plate is sandwiched between the side wall lower end surface of the scuff plate and the vehicle body panel, and the edge of the floor carpet is used as a fixing member for the floor carpet. It is preferable to provide a hooking part that hooks into a hole provided in.
With this configuration, the floor carpet can be fixed simply by hooking the hook portion of the fixing member into the hole provided in the floor carpet, and the lower end surface of the side wall of the scuff plate is abutted against the fixed floor carpet. Since it is sandwiched between the scuff plate and the vehicle body panel, the floor carpet can be more firmly fixed, and displacement of the floor carpet can be prevented.
In addition, since the edge of the floor carpet is fixed by the hook portion, even if the floor carpet is pulled, the hook portion does not come into contact with the inner surface of the scuff plate, and the edge of the floor carpet is securely fixed. be able to.

The fixing member of the floor carpet is preferably formed integrally with a clamp for fixing the protector to the vehicle body panel, and the clamp is formed separately from the protector and attached to the protector.
According to the above configuration, the protector can be molded by extrusion molding with the same cross section in the direction perpendicular to the length direction of the protector at any location, and the protector molding die can be reduced in size and cost. Can be reduced.
In addition, it is possible to minimize the increase in the number of parts by providing the fixing member integrally with the clamp provided separately from the protector, and to attach the clamp and the fixing member to the protector in one installation operation. It is possible to facilitate the installation work.
The clamp or / and the fixing member may be provided integrally with the protector, but in this case, the injection molding is performed by the upper and lower molds instead of the extrusion molding.

  Further, a washer hose, an opener cable and / or an antenna cable is inserted in a space between the vehicle body panel and the scuff plate and at an outer position of the protector, and a holding member for the hose or / and the cable is inserted into the protector or the clamp. It is preferable that they are provided integrally with the projection.

According to the above configuration, the washer hose, the opener cable and / or the antenna cable are supported by the mounting portion integrally provided on the protector or the clamp and are routed along the outer surface of the protector. Alternatively and / or cable routing can be facilitated without increasing the number of parts.
In addition, since the washer hose, the opener cable and / or the antenna cable are routed outside the protector, the influence of heat generated from the wire harness can be reduced.
Thus, the protector used in the wiring structure of the wire harness according to the present invention not only allows a large number of wires to be routed in the space between the vehicle body panel and the scuff plate, but also fixes the scuff plate, the floor carpet, the washer hose, and the opener. A number of functions of securing cables and / or antenna cables can be performed.

  As described above, according to the present invention, the wire harness that is routed in the space between the vehicle body panel and the scuff plate is taped and fixed to a clamp that is a fixing member for the vehicle body so that the circular cross section is routed. Rather than being inserted into the hollow portion of the closed cross section of the protector and being routed in the space, there is no need to bind the wire group of the wire harness with tape. And since the upper wall or bottom wall of the protector is a double door opening / closing lid, the wire group constituting the wire harness can be easily put into the protector in a disassembled state, and the protector is housed in a heaped state. However, by closing the open / close lid from the left and right, the electric wire group can be dispersed on the side wall, and the electric wire group can be filled into the protector without a gap, so that the capacity of the electric wire in the protector can be enhanced. Therefore, by increasing the size of the protector so as to occupy the space between the vehicle body panel and the scuff plate, it is possible to cope with an increase in the number of wires in the wire harness. As a result, it is not necessary to route the increased number of electric wires to another route, and the wiring harness protector, stopper, and the like, which are required for the other route, are unnecessary, and the cost can be reduced.

In addition, since the scuff plate is fixed by locking the locking portion provided on the protector with the locked portion provided on the scuff plate, there is no need to screw the scuff plate to the vehicle body panel, and the fixing to the vehicle body is not necessary. Only fixing the protector is sufficient, and workability can be improved.
Furthermore, since the floor carpet is fixed by a fixing member fixed to the vehicle body panel as a single body or separately from the protector, it is not necessary to fix the floor carpet with an adhesive.
