Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiring structure of a wire harness which is wired on a pop-up roof of a vehicle.

[0002]

[Prior Art]

 Some vehicles, such as camper vans, have a pop-up roof that has a flip-up roof with an opening in the ceiling of the vehicle body house in order to expand the interior space upward.

As shown in FIG. 3, the structure of a pop-up roof is such that a rear end of a hop-up roof (hereinafter, simply referred to as a roof) 2 is connected to a rear end of a roof of a house body 1 by a hinge 3, and a front part of the roof is joined. The foldable link arms 4 can be held at the left and right ends thereof in the raised position. A gas damper 9 is provided at an intermediate portion of the roof 2 in the front-rear direction to apply a roof lifting operation force. A roof tent T is attached between the outer periphery of the roof of the house body 1 and the outer periphery of the roof 2. Further, a lamp 7 for illumination is provided at the center of the front end of the roof 2.

The link arm 4 is composed of an arm 4A and an arm 4B, and as shown in FIG. 4, connecting members 5A and 5B are attached to their respective ends to be axially coupled so as to be relatively rotatable.

[0005]

[Problems to be solved by the device]

 By the way, the wire harness W is wired from the main body 1 side to the lamp 7 of the roof 2, but when wiring is performed in a short path along the link arm 4, when the link arm 4 is folded as shown in FIG. The harness W can be bent. The bent shape is irregular, and there is a possibility that it may be slackened and may be caught between the connecting members 5A and 5B, or that it may be bent at an acute angle to cause a line break.

For this reason, the wiring along the link arm 4 is avoided, and as shown in FIG. 3, the wire harness W is formed along the ceiling from its front part to its rear part and further along the roof 2 from its rear part to its front part. Is wired. Therefore, it becomes a long path, which causes a problem of interference with other parts, and it is necessary to increase the wire diameter due to the voltage drop, and the wire length becomes long, resulting in an increase in cost.

Therefore, an object of the present invention is to provide a wiring structure of a wire harness that can be safely wired along the link arm 4, and particularly a wiring structure of a connecting portion of the link arm 4.

[0008]

[Means for Solving the Problems]

 As shown in FIG. 1, the present invention provides a cover plate 6 on the outer surface of the connecting portion 5A of the link arm 4 so as to face the connecting portion 5A with a gap therebetween. Are provided with pins 71, 72, 73 that abut against the mating surface at these central positions and at a plurality of positions on the bending side of the link arm with respect to the central position. A wire harness W is inserted between the pins 72 and 73.

[0009]

[Action]

 As shown in FIG. 2, when the link arm 4 is folded, the bent shape of the wire harness W 1 is regulated by the pins 71, 72, 73, so that the wire harness W 1 is irregularly bent and is not caught or broken. There is no danger of it occurring. Moreover, the wiring path is significantly shortened compared to the conventional one.

[0010]

【Example】

 As shown in FIGS. 1 and 3, the link arm 4 that lifts the roof at its front end is formed by connecting the arms 4A and 4B and is foldable.

As shown in FIG. 1, a forked connecting portion 5A having flat plate portions 51 and 52 facing each other is attached to the lower end of the link arm 4A. On the other hand, a connecting portion 5B inserted between the flat plate portions 51 and 52 is attached to the upper end of the link arm 5B. The connecting portions 5A and 5B are connected to each other by pivotally supporting the connecting portion 5B of the arm 4B on a support shaft (not shown) provided between the flat plate portions 51 and 52 on the arm 4A side. A spring 53 for urging the arms 4A and 4B to the upright position is provided between the connecting portions 5A and 5B.

A convex portion 512 is formed at the center of the outer surface 511 of the flat plate portion 51 of the connecting portion 5A, and a cylindrical pin 71 is welded to this. A screw 711 is formed on the inner surface of the pin 71 on the protruding end side.

Reference numeral 6 denotes a disk-shaped cover plate, which has a hole 61 formed at the center thereof for inserting the protruding end of the pin 71, and two small diameter pins 72, 73 projectingly provided on one surface. There is. The cover plate 6 causes the tips of the pins 72 and 73 to abut against the outer surface 511 of the connecting portion 5A, inserts the projecting end of the pin 71 into the hole 61, and screws the bolt 8 into the projecting end. It is fixed to the outer surface 511 with a gap therebetween. The positions of the pins 72 and 73 are positions on the folding side of the link arm 4 with respect to the center pin 71.

The wire harness W extends along the arm 4B from the vehicle body house side, and is inserted between the pin 71 and the pins 72 and 73 on the sides at the connecting portion, and further wired along the arm 4A. , Is connected to a lamp 7 (FIG. 3) provided at the front end of the roof 2. The wire harness W is fixed to the arms 4A and 4B by the clamp 10. The inner surface of the cover plate 6 that comes into contact with the wire harness W is lubricated to reduce the sliding contact resistance with the wire harness W.

In the above wiring structure, the wire harness W is repeatedly bent every time the roof 2 is raised and lowered at the connecting portion of the link arm 4, but when the link arm 4 is folded, as shown in FIG. W is regulated by the pin 71 sandwiching the pin 71 and the pins 72 and 73, and the bent shape has a substantially constant gentle curve. Therefore, it does not become an irregular slack shape and is not caught between the connecting portions 5A and 5B, and is not rubbed by the peripheral edge of the connecting portions 5A and 5B. Is unlikely to occur.

[0016]

[Effect of the device]

 According to the wiring structure of the wire harness of the present invention, when the wire harness is wired along the foldable lifting link arm of the pop-up roof, the wire harness is not damaged by the operation of the foldable connecting portion of the link arm. .. Therefore, the wire harness connected to the lamps at the front end of the roof can be routed along the shortest path along the link arm.
