ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electricity supplying structure on motor vehicle sliding door and more particularly, to an electricity supplying structure on motor vehicle sliding door wherein a sliding block to which a door side wiring harness is secured engages slidably a guide rail provided on a motor vehicle sliding door so that a connecting position between the door side wiring harness and the body side wiring harness remains still when the sliding door is opened or closed.
2. Description of the Related Art
Various means for connecting a door the wiring harness provided for auxiliary units such as a power window motor, a door locking unit, a speaker, and the like installed in a sliding door of a motor vehicle to a body side (i.e. an electricity supply side) wiring harness have been provided, conventionally.
FIG. 16
shows, for an example, a prior art electricity supplying structure on motor vehicle sliding door disclosed in Japanese U. M. Reg. Application Laid-open No. 4-124555. Referring to
FIG. 16
, auxiliary units
102
in the sliding door
101
are connected to a wiring harness
104
through a controller
103
, and the end of the wiring harness
104
is connected to a contact point
105
provided on the door front end portion. Another contact point
107
connected to a battery
109
through a wiring harness
108
is provided on the body
106
. The contact point
107
is connected to the contact point
105
through a movable contact point (not shown) provided for dustproofing and waterproofing.
With respect to the above structure, however, electric connection is made only when the sliding door
101
is closed, and accordingly the auxiliary units installed thereon can not operate in case that the sliding door
101
opens even a little. And, the movable contact point (not shown), which causes a double contact points, increases contact resistance, thereby lowering contact reliability.
Also, Japanese U. M. Reg. Application Laid-open No. 5-28893 discloses another electricity supplying structure on building door (not shown), wherein a pair of tubular arms are linked with a lining axis, one of the arms is fixed to a building door, the other of the arms is fixed to a building, and an electric wire is put through the arms.
The above structure, however, cannot be applied to a motor vehicle sliding door which moves two-dimensionally or three-dimensionally on opening or closing.
In order to solve the above problems, other electricity supplying structures on motor vehicle sliding door shown in
FIGS. 17A
,
17
B,
18
A, and
18
B are disclosed in Japanese Patent Application Laid-open No. 7-222274.
In the structure shown in
FIGS. 17A and 17B
, a supporting bar
113
is provided along a guide rail
112
attached to a portion of a vehicle body
117
relative to a sliding door
111
, and an electric wire (i.e. a wiring harness)
114
spirals on the supporting bar
113
. One end of the electric wire
114
is connected to a speaker
116
installed in the sliding door
111
by way of a hinge
115
and the other end of the electric wire
114
is connected to an audio set (not shown) installed on the vehicle body
117
. In a door-closed state of
FIG. 17A
the electric wire
114
extends along the supporting bar
113
, and in a door-opened state of
FIG. 17B
the electric wire
114
is compressed.
And, in the structure shown in
FIGS. 18A and 18B
, a reel
120
capable of winding and releasing an electric wire (i.e. a wiring harness)
119
during opening-closing movement of a sliding door
118
is provided on a vehicle body
121
. One end of the electric wire
119
is connected to a speaker
123
installed in the sliding door
119
by way of a hinge
122
and the other end of the electric wire
119
is connected to an audio set (not shown) installed on the vehicle body
121
. In a door-closed state of
FIG. 18A
the electric wire
119
extends from the reel
120
, and in a door-opened state of
FIG. 18B
the electric wire
119
is wound by the reel
120
.
With respect to the structure shown in
FIGS. 17A and 17B
, however, the spiral electric wire
114
requires a longer electric wire, which causes a higher electric loss. And, a wiring harness having electric wires with a larger diameter or having a larger number of electric wires, which has a poor bending property and requires a larger accommodation space, can not be applied to this method.
And, with respect to the structure shown in
FIGS. 18A and 18B
, however, a complicated mechanism for preventing the electric wire
119
from twisting is required. And also, a wiring harness having electric wires with a larger diameter or having a larger number of electric wires, which has a poor bending property and requires a larger accommodation space, can not be applied to this method. Further, with respect to the structures shown in
FIGS. 17A
,
17
B,
18
A, and
18
B, since the electric wires
114
,
119
are bent and extended iteratively, conductors of the electric wires
114
,
119
are likely to be damaged.
SUMMARY OF THE INVENTION
In view of the foregoing, an object of the present invention is to provide an electricity supplying structure on motor vehicle sliding door which can solve the above-described problems, wherein a slider, to which a door side wiring harness is secured, engages slidably a guide rail provided on a motor vehicle sliding door so that a connecting position between the door side wiring harness and the body side wiring harness remains still when the sliding door is opened or closed.
In order to achieve the above-described object, as a first aspect of the present invention, an electricity supplying structure on motor vehicle sliding door in accordance with the present invention includes: a sliding door; a guide rail provided on the sliding door; a slider to slidably engage the guide rail; and a wiring harness secured to the slider and extending to a vehicle body side; wherein a bent portion is formed on the wiring harness between the slider and the vehicle body side.
As a second aspect of the present invention, in the structure with the above first aspect, the electricity supplying structure further includes a wiring harness supporting guide provided over the guide rail for hanging the wiring harness from the wiring harness supporting guide toward the slider.
As a third aspect of the present invention, in the structure with the above second aspect, the electricity supplying structure further includes a reel to pull the slider in a single direction.
As a fourth aspect of the present invention, an electricity supplying structure on motor vehicle sliding door in accordance with the present invention includes: a sliding door; a guide rail provided on the sliding door; a slider to slidably engage the guide rail; a pair of linking arms being linked to each other, one end of the linking arms being connected to the slider and the other end of the linking arms being connected to the sliding door; and a wiring harness arranged by way of the pair of linking arms to the slider and extending to a vehicle body, wherein a bent portion is formed on the wiring harness between the slider and the vehicle body.
As a fifth aspect of the present invention, in the structure with the above fourth aspect, the pair of linking arms are arranged on an upper side of the guide rail.
As a sixth aspect of the present invention, in the structure with any one of the above aspects, the guide rail is a plate having a slit and the slider has a supporting axis to slide in the slit.
As a seventh aspect of the present invention, in the structure with either one of the above fourth and fifth aspects, the one of the pair of linking arms is connected to the slider by means of an axis portion and the axis portion engages the slit of the guide rail.
