Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a wiring structure applicable to a vehicle door having a large opening such as a double door.

(Prior art) For example, the wiring structure of a conventional vehicle door is as follows.
The one described in Japanese Utility Model Application Publication No. 113566/1983 (name of invention, wiring structure for vehicle door) is known.

In this conventional vehicle door wiring structure, wiring through-holes are formed on the door opening side and the door side of the vehicle body, and a base end is provided near one of the through-holes. A protector is provided that is fixed and has a distal end passing through the other through hole and having a wire extending inwardly inserted therethrough, and the protector has a bending portion that is easily bent on the fixed side. A sliding portion that is difficult to bend is provided between the bent portion and the tip end, and when the door is closed, the sliding portion of the protector slides inward of the other through hole. This prevents the wiring inserted through the protector from loosening in the gap between the door opening of the vehicle body and the door.

Therefore, since the relative displacement between the vehicle body and the door when the door is opened and closed is absorbed by the sliding of the protector, the protector will sag between the vehicle body and the door when the door is closed, compared to simply covering the wiring with a protector. This meant that there was no need to worry about handling or pinching the slack part.

(Problem to be solved by the invention) However, in the conventional wiring structure of a vehicle door, the protector is composed of a bending part that is easy to bend and a sliding part that is difficult to bend. , there were problems as described below.

Since the protector always bends from the bent portion when the door is opened and closed, the bending force is concentrated at one point, and there is a risk that the wiring and the protector may be cut or damaged.

If the opening degree of the door is increased, the sliding part may act as a lever using the center of rotation of the door as a fulcrum because it is made of a material that is difficult to bend, restricting the opening movement of the door, or the sliding part may Therefore, it is necessary to restrict the degree of opening of the door with a stopper or the like, and if this is done, the door cannot be fully opened, making it difficult to use.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems.To achieve this purpose, the present invention has a door mounted on the vehicle body that can be opened and closed by a pivot. A space is formed between the door side edge formed on the support shaft side of the door and the vehicle body side edge formed on the support shaft side of the vehicle body, and the door side edge and In the wiring structure of the vehicle body door in which insertion holes are formed in the side edges of the vehicle body so as to communicate the space portion with the interior space of the vehicle body and the door, and wiring is installed between both the insertion holes, the space The wiring of the section is provided with an elastic protector formed into a substantially U-shape, one end of the protector is fixed near one of the two insertion holes, and the other end is fixed near the other insertion hole. A flexible reinforcing member is attached to the wiring at the other end of the protector along the wiring, and the reinforcing member is slidable into the other insertion hole when opening and closing the door. Between the wiring and the vehicle body, which are inserted together with the wiring and located in the interior space on the other side of the insertion hole, the wiring is pulled out from the interior space when the door is fully opened, and the wiring is pulled out excessively when the door is fully opened. The means is characterized in that a stopper is provided for limiting the extent to which the protector is in an extended state.

(Function) Therefore, in the wiring structure of the vehicle body door of the present invention, by using the above-mentioned means, when the door is opened, the wiring and the reinforcing member slide and are inserted as the door opens and rotates. When the wire is pulled out from the hole and the sliding movement of the wire is restricted by the stopper while the door is fully open, the bent portion of the elastic U-shaped protector is stretched and deformed.

Then, when the door is closed, the protector returns to its original U-shape as the door closes and rotates, and when a predetermined amount of restoration is achieved, it is pushed toward the other end of the protector and the wiring and reinforcing member slides into the insertion hole.

As described above, the relative displacement between the door and the vehicle body when the door is opened/closed can be absorbed by the elongation, deformation, and restoration of the protector and the sliding of the wiring and reinforcing members.

Since the protector is made of an elastic material and is formed into a U-shape, the bending force that acts on the protector when opening and closing the door is distributed over the entire bent portion.

Further, the other end of the protector that supports the sliding portion of the wiring is arranged near the insertion hole, and further,
Since this sliding part is provided with a reinforcing member, it slides smoothly into the insertion hole, and furthermore, bending force is not concentrated only on the wiring at the exposed part of the wiring from the protector and the sliding part. In addition, since the reinforcing member has flexibility, it can be prevented from being deformed and damaged when a large force is applied.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In describing this embodiment, the wiring structure of a double door, which is used as a back door of a one-box type automobile, will be taken as an example.

The wiring structure of the car body door of the embodiment is as shown in FIG.
It is arranged between the insertion holes 20, 30, the wiring 40, the protector 50, and the sub line (reinforcing member) 6.
The main components are 0.70.

The double door 10, as shown in FIG.
Consists of a left door 11 and a right door 12, both doors 11,1
2 are pivotally connected to the rear of the vehicle body by support shafts 13a of two hinges 13 so as to be openable and closable, and have a large opening angle of 90 degrees or more.

Further, a space 200 is formed between the door side edge 111 formed on the 13a side of the left door 11 and the vehicle body side edge 101 formed on the support shaft 13a side of the vehicle body 100.
are formed, both the insertion holes 20 and 30 face this space 200, the insertion hole 20 is opened in the door side edge 111 of the left door 11, and the other insertion hole 30 is opened in the door side edge 111 of the left door 11. , as shown in FIG. 2, the insertion hole 2
A hole is formed in the side edge 101 of the vehicle body 100 at a position higher than zero. And both insertion holes 2
Rubber grommets 21 and 31 are fitted into the holes 0 and 30, respectively. The grommet 31 has a sliding hole 32 through which the wiring 40 and the sub-wires 60 and 70 are slidably inserted, and the other grommet 21 has a sliding hole 32 of a size that allows only the wiring 40 to be inserted. A hole 22 is opened.

The protector 50, as shown in FIG.
The wire 40 is inserted into the space 200, and the protector 50 is formed into a U-shape made of rubber that has elasticity when the door is closed. It is located near the hole 20 and fixed to the door side edge 111 of the left door 11 with a clamp 51, and the other end 53 is provided so as to be placed near the insertion hole 30 when the door is closed. .

As shown in FIG. 1, the wiring 40 extends from both the insertion holes 20 and 30 to the left door 11 and the interior space of the vehicle body 100, and one end thereof connects to the license plate provided on the outer surface of the left door 11. 110, and the other end is connected to the power supply side.

Further, as shown in FIGS. 1 and 4, this wiring 40 is connected to a protector 5 on the fixed side of the protector 50.
A sliding exposed portion 41, which is fixed with the clamp 51 together with the grommet 31 and exposed from the other end 53 of the protector 50, is slidably inserted into the insertion hole 30 via the grommet 31.

The sub-wires 60 and 70 are flexible wires made of the same material as the wiring 40 provided along the sliding exposed portion 41 as reinforcing members for the wiring 40, and are flexible. It is slidably inserted into the insertion hole 30 via the grommet 31. Further, the sub-lines 60 and 70 are provided so that their positions along the wiring 40 are shifted from each other by a length l, as shown in FIG. Further, a stopper 80 is fixed to the wiring 40 and the sub-wire 60 on the interior space side of the vehicle body 100, which abuts against the grommet 31 on the vehicle body side 100 to restrict sliding of the wiring 40 toward the pull-out side.

Note that the stopper 80 is fixed at a position where the protector 50 is almost completely extended when the door is fully open, but the wiring 40 is fixed at a position where the stopper 80 itself is not directly inputted with an excessive tensile force from the left door 11. This is the position it was in when it was pulled out.

Next, the operation of the embodiment will be explained.

When the left door 11 is opened from the closed state shown in FIG. 200.

After the wiring 40 has been pulled out by a predetermined amount, the stopper 80 is brought into contact with the grommet 31 and the wiring 40 is pulled out.
Once the sliding of the protector 50 is restricted, the protector 50 is extended as shown in FIG. In this state, the left door 11 is fully opened.

Note that even if the protector 50 hits the door side edge 111 of the left door 11 in this state, the protector 50 is made of an elastic material and is easily bent.
This will not hinder the opening and rotation of the protector 50, and the protector 50 will not be damaged. In addition, the wiring 40
Since the sub-wires 60 and 70 are flexible, they can be bent without being damaged or cut.

When the left door 11 is closed from the fully open state shown in FIG. When this happens, a force in the pushing direction acts from the other end side 53 of the protector 50 to the sliding exposed portion 41 of the wiring 40, and this other end side 53 tries to return to a position near the insertion hole 30, and this action As a result, the sliding exposed portion 41 and the sub wires 60 and 70 slide and enter the interior space 100 of the vehicle body 100 from the insertion hole 30.
Enter a.

In addition, when the sliding exposed part 41 enters, since the sliding exposed part 41 is reinforced by the sub-wires 60 and 70, it will not bend and sag in the space 200, and will not be able to penetrate from the insertion hole 30 into the internal space 100a. It is easy to enter straight into the body, and the sliding movement is very smooth.

Furthermore, since the sub-wires 60 and 70 are both provided with an offset of l, the bending force acting on the position near the stopper 80 where the wiring 40 is bent the most is alleviated, and local concentration of bending force is avoided. be able to.

As explained above, the wiring structure of the vehicle door of the embodiment provides the following effects.

The protector 50 is made of elastic rubber.
Since the wire 40 is shaped like a letter, the bending force that acts on the bent portion of the protector 50 when the left door 11 is opened and closed acts in a distributed manner over the entire bent portion. The protector 5 does not have a bending force concentrated on one point, and is easily bent even if it comes into contact with the left door 11 and is bent.
0 is hard to damage.

Even if the opening degree of the door is increased, the relative displacement between the left door 11 and the vehicle body 100 when the door is opened and closed can be absorbed by the sliding exposed portion 41 of the wiring 40 and the sliding of the sub wires 60 and 70 as reinforcing members. Moreover, since the protector 50 is made of an elastic material, it is easily bent and does not become an obstacle to the rotation of the door.Furthermore, when the door is closed, the wiring 40 is
00 and the left door 11, or being exposed inside or outside the vehicle body 100 can be prevented.

The bending force of the sliding exposed portion 41 of the wiring 40 is alleviated by the sub-wires 60 and 70 as reinforcing members, and the wiring 40 can be prevented from being cut due to repeated bending, and the insertion hole 3
Smooth sliding in and out of 0.

Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment. For example, in the embodiment, a wiring structure used for a double door is taken as an example. The present invention is not limited to this, and may be applied to any door that can be rotatably attached to the vehicle body.

Further, in the embodiment, the protector and the wiring are fixed to the door side, but they may be fixed to the vehicle body side, or the protector and the wiring may be fixed separately.

Further, in the embodiment, the reinforcing member is made of the same material as the wiring, but is not limited to this, and may be made of an elastic material such as rubber.

Further, although rubber is used as the protector, any elastic material such as synthetic resin may be used as long as it can be formed into a U-shape and has flexibility.

(Effects of the invention) As explained above, in the wiring structure of the vehicle door of the invention, by forming the protector into a U-shape,
Since the bending force acting on the protector is dispersed,
Cutting of the protector and wiring due to concentration of bending force
This has the effect of preventing damage. Moreover, since reinforcing members are provided at the sliding exposed parts of the wiring, the bending force is not concentrated only on the wiring, and this has the effect of preventing the wiring from being cut due to bending force. You can also get

In addition, since the means allows for smooth sliding on the wiring, it is possible to obtain the effect that the wiring fits well.

In addition, in the wiring structure of the present invention, since the flexibility of the protector and the sliding of the wiring are used as a means to absorb the relative displacement between the door and the vehicle body, the protector does not restrict the opening movement of the door. The door can be fully opened without causing any damage.
