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 protector through which the wire harness is inserted is accommodated in the space, and the protector has an upper wall along the inner surface of the upper wall of the scuff plate, and has a reverse concave shape in cross section including both side walls facing both side walls in the width direction of the scuff plate. The protector main body and a bottom wall material that is a separate member that closes the bottom-side opening of the protector main body, and engaging portions provided at the lower ends of both side walls of the protector main body at both ends in the width direction of the bottom wall material Although the locked portion for locking is provided, the region excluding the locked portion is shaped along the shape of the vehicle body panel, and the protector body is used for other vehicle types. On the other hand, the bottom wall material is a vehicle-specific product,
The bottom wall material of the protector is clamped by the vehicle body panel, and the locking portions provided on both side walls or the top wall of the protector are locked by the locked portions provided on the inner surface side of the scuff plate. A wiring harness wiring structure is provided, which is characterized by being configured as described above.

As described above, in the present invention, the wire harness routed in the space between the vehicle body panel and the scuff plate is inserted into the hollow portion of the closed cross-section of the substantially box-shaped protector composed of the protector body and the bottom member. In order to route the wires, the wires of the wire harness do not need to be bound with tape, and can be inserted into the protector one by one in a disassembled state. 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, the protector body has an opening on the entire bottom wall of the protector body, so that when the wire harness is inserted, the top and bottom are reversed so that the bottom wall opening is the top opening. Can be filled. What is necessary is just to reverse so that it may become the arrangement | positioning attitude | position to a vehicle, after closing with a bottom wall material after electric wire filling.
In addition, since the bottom wall material is arranged along the upper surface of the vehicle body panel (side sill), the shape of the vehicle body panel may differ depending on the vehicle type. The protector can be locked and fixed to the vehicle body panel in a stable posture. On the other hand, if the height of the side wall of the protector body to which the bottom wall material is assembled corresponds to the height of the side wall of a general scuff plate, it can be used for other vehicle types. In addition, when the vertical distance between the vehicle body panel and the scuff plate is particularly wide, the bottom wall material can be adjusted. Moreover, since it is set as the simple shape of a cross-section reverse concave shape, it can extrude and can be cut | disconnected and used according to the length of the scuff plate corresponding to each vehicle type. Thus, since the protector body can be used as a common product with other vehicle types, the manufacturing cost of the protector can be greatly reduced.

  Further, in the present invention, since the locking portion provided on the protector body is locked with the locked portion provided on the scuff plate, and the scuff plate is locked and fixed to the protector, the bottom wall material of the protector is attached to the vehicle body panel. The scuff plate does not need to be screwed 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.

  The upper wall of the protector body is disposed in contact with the inner surface of the upper wall of the scuff plate, and is disposed over the entire length of the scuff plate, while the bottom wall of the protector is opposed to the scuff plate with a space therebetween. It is preferable to arrange | position along the upper surface of this.

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 to accommodate the increase in the number of wires in the wire harness. . 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 fixed firmly with a clamp that fixes the protector to the body of the protector.

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.
In addition, the protector of the present invention is composed of a protector body having a reverse concave shape in cross section and a bottom wall material along the top surface shape of the vehicle body panel, so that the bottom surface opening of the protector body is turned upside down to form the top surface opening. When the electric wire group is inserted, the electric wire group constituting the wire harness is easily put into the protector in a disassembled state.
Further, the protector main body can be reduced in cost by being used for other vehicle types, while the bottom wall material along the vehicle body panel can be fixed to the vehicle body panel in a stable posture by being dedicated to the vehicle type.
In this way, while the protector bottom wall material follows the shape of the vehicle body panel, the protector body extends along the inner surface of the scuff plate, thereby increasing the size of the protector to the extent that it occupies 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.

Embodiments of the present invention will be described with reference to the drawings.

Side plate side plates 201d and 201e having the same height are provided on both sides of the flat plate portion 201c of the bottom wall member 201. The spherical portions 201a and 201b are provided at the upper ends of the side plates, and are fitted and fixed to the spherical concave portions 20c1 and 20d1 on the protector body 200 side.

  In the protector 20 having the above-described shape, when inserting the wire w of the wire harness W / H, the protector main body 200 is reversed upside down, and the bottom surface opening is set as the upper surface side, and the wires w are inserted without being bundled. . After the insertion, the bottom wall material 201 is closed and fixed to the protector main body 200. By reversing again in this state, the bottom wall material 201 is set to the bottom surface side.

Locked claws 20j and 20j protrude from both sides of the upper wall 20b of the protector body 200 in the width direction, while the locked claws 13b and 13b protrude downward from the inner surface of the upper wall 13a of the scuff plate 13. These locking claws 13b are locked to the locked claws 20j of the protector 20.
Therefore, the scuff plate 13 is covered with the protector 20 containing the electric wire, and the locking claw 13b is locked to the locked claw 20j, so that the protector 20 can fix the scuff plate 13.

  Further, the bottom wall member 201 of the protector 20 is provided with a through hole 20h for attaching a clamp at a required interval (200 mm in this embodiment) in the length direction, and the clamp 30 is locked. As shown in FIG. 4, the clamp 30 is provided with a locking portion 30b inserted and locked in a through hole 20h provided in the bottom wall 20a of the protector 20 on the upper surface side of the flat base portion 30a. A locking portion 30c that is inserted and locked into the through-hole 12c provided in the upper wall 12a of the side sill 12 is provided on the lower surface side of the position facing the top and bottom. Further, one end of the base is bent upward, the bent side is used as a hooking portion 30d as a fixing member for a floor carpet, and a locking claw 30e is provided at the tip of the hooking portion 30d. The hooking portion 30d protrudes to the outer surface side of one side wall 20d of the protector 20.

  Further, the floor carpet 40 laid on the floor panel 11 is extended to the vicinity of the side wall 20d of the protector 20, and the hook portion 30d of the clamp 30 is inserted into the hole 41 provided at the edge of the floor carpet 40 from the lower surface side. The engaging claw 30e provided at the tip of the hooking portion 30d is hooked on the hole periphery on the upper surface side of the floor carpet 40. Further, the lower end surface 13d of the side wall 13c of the scuff plate 13 is abutted against the upper surface of the floor carpet 40 hooked on the hooking portion 30d, and the floor carpet 40 is sandwiched between the scuff plate 13 and the side sill 12.

  Further, the clamp 30 integrally protrudes a mounting member 30f that holds a washer hose 50 and an opener cable 51 that are spatially arranged between the hook portion 30d and the outer surface of the side wall 20d of the protector 20. Has been established. A partition portion projects from the middle of the attachment portion 30f, a washer hose holding portion 30g is provided on the lower side, and an opener cable holding portion 30h is provided on the upper side.

It is said.

In the wiring structure of the wire harness, the assembling procedure is to attach the clamp 30 to the protector 20 and accommodate the wire w of the wire harness W / H in the protector 20. In this state, the protector 20 is disposed along the upper surface of the side sill 12 of the vehicle body panel, and the locking portion 30c of the clamp 30 is inserted and locked into the through hole 12c of the side sill 12.
Next, the floor carpet 40 is fixed by hooking the latching claws 30e of the catch 30d of the clamp 30 into the hole 41 at the edge of the floor carpet 40.
Finally, the scuff plate 13 is covered with the protector 20, and the claw plate 13 is fixed by the protector 20 by locking the locking claw 13b to the locked claw 20j.

  In this state, the upper wall 20b of the protector 20 substantially contacts the inner surface of the upper wall of the scuff plate 13, while the bottom wall 20a substantially contacts the upper surface of the side sill 12, and the protector 20 has a space S between the side sill 12 and the scuff plate 13. It will be arranged over the entire height direction.

According to the said structure, since the wire harness routed in the space S between the side sill 12 and the scuff plate 13 passes through the inside of the protector 20 and is covered with the protector 20, it is not necessary to carry out tape binding as in the conventional case. Therefore, the electric wires can be inserted into the protector 20 in a disassembled state, not as a mass having a circular cross section. Moreover, since the protector 20 is shaped on the inner surfaces of the side sill 12 and the scuff plate 13 to increase the volume thereof, the protector 20 can be passed through the protector 20 even if the number of wires of the wire harness W / H increases.
Moreover, while the protector main body 200 can be reduced in cost by using other vehicle models, the bottom wall material 201 along the side sill 12 can be fixed to the side sill 12 in a stable posture by dedicated to the vehicle model.

Furthermore, since the clamp 30 for fixing the protector 20 to the side sill 12 is provided separately from the protector 20 and the cross section in the direction orthogonal to the length direction of the protector 20 is the same at any location, the protector 20 is extruded. Molding can be performed by molding, and the mold for protector molding can be reduced in size to reduce costs. In addition, when the protector 20 is molded by extrusion molding, a through hole 20h is formed after the molding.
The clamp or / and the fixing member may be provided integrally with the protector. In this case, the protector is formed by injection molding.

  Further, in the present invention, since the scuff plate 13 is fixed to the protector 20, it is not necessary to screw the scuff plate 13 to the side sill 12, and the attachment work of the scuff plate 13 can be facilitated.

Furthermore, the floor carpet 40 can be fixed simply by hooking the hook portion 30 d provided integrally with the clamp 30 into the hole 41 provided in the floor carpet 40.
Furthermore, since the lower end surface 13d of the side wall 13c of the scuff plate 13 is abutted against the fixed floor carpet 40 and is sandwiched between the scuff plate 13 and the side sill 12, the floor carpet 40 can be fixed more firmly. The positional deviation of 40 can be prevented.

Further, since the washer hose 50 and the opener cable 51 are supported by the attachment portion 30f provided integrally with the clamp 30 and are routed along the outer surface of the protector 20, the washer hose 50 and the opener cable 51 are routed. Can be easily achieved 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.

The present invention is not limited to the above-described embodiment, and a holding member for a washer hose or an opener cable and a fixing member for a floor carpet may be formed separately from the clamp and connected and fixed to the clamp.
Alternatively, the protector may be formed by integrally projecting a fixing portion of the floor carpet and a holding portion such as a washer hose.
