JP 2017-206051 A

In an automobile in which the power supply device 301 is mounted, when the position of the lower end 52a of the door trim 52 is lowered due to vehicle requirements, the friction between the lower end 52a and the corrugated tube 22 increases, and the wire movement associated with the opening and closing of the slide door 5 increases. There was a possibility that the operability of the harness 302 would deteriorate.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a power supply device capable of smoothly operating a wire harness when opening and closing a slide door.

In order to solve the above problems, the power supply device of the present invention is a power supply device provided with a wire harness that is routed from a vehicle body of an automobile to a slide door, wherein the wire harness protects the wire and the wire. a protection tube; and a curvature regulating member that is inserted into the protection tube and restricts curvature of the protection tube. a plurality of piece portions erected from the end portion in the width direction of the portion and arranged in the longitudinal direction of the connecting portion, wherein the bending regulating member is oriented such that the connecting portion is inside and the piece portion is outside. In the opposite direction, the bending is restricted by contact between the adjacent pieces. is located on the lower side, and the vicinity of the end portion of the curving regulating member on the side of the sliding door has a greater degree of curving allowance to be convex upward than the other portions.

According to the present invention, since the vicinity of the end portion of the curving regulating member on the side of the sliding door has a greater degree of curving tolerance to project upward than the other portion, the wire harness is curved upward at the lower end of the door trim of the sliding door. The wire harness can be gently bent downward in front of the sliding door when the wire harness is pulled between the door panel and the door trim. As a result, contact between the lower end of the door trim and the wire harness with a high contact pressure can be suppressed, so that the wire harness can be smoothly operated when opening and closing the sliding door.

A “power supply device” according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG.

The power supply device 1 shown in FIGS. 1 and 2 is mounted on a vehicle and performs power supply and signal transmission from the vehicle body to the electrical components of the slide door 5 . The power supply device 1 includes a wire harness 2 routed from a vehicle body to a slide door 5, a body side unit 3 supporting a corrugated tube 22 constituting the wire harness 2 so as to be swingable on the vehicle body side, and a corrugated tube. 22 on the slide door 5 side so as to be swingable.

Arrow X in FIGS. 1 and 2 indicates the width direction of the vehicle, arrow Y indicates the longitudinal direction of the vehicle, and arrow Z indicates the vertical direction of the vehicle. The sliding door 5 slides in the longitudinal direction of the vehicle. 1 and 2 show the state of the power supply device 1 when the slide door 5 is half open. are the same. Further, the trajectory of the wire harness 2 from when the slide door 5 is fully closed to when it is fully opened is substantially the same as that of the conventional product shown in FIG. The half-opened slide door 5 shown in FIG. 1 is closed by sliding to the right in the drawing, and is fully opened by sliding to the left in the drawing.

The body-side unit 3 includes a rotor 32 attached to the outer circumference of the corrugated tube 22, and a body protector 31 fixed to the vehicle body and attached to the rotor 32 so as to be swingable in three-dimensional directions. Further, as shown in FIG. 2, a weather strip 9 is attached to the widthwise end of the vehicle body.

The door-side unit 4 includes a rotor 42 attached to the outer circumference of the corrugated tube 22, and a door in which the rotor 42 is fixed to the door panel 51 of the sliding door 5 so as to be swingable about a swing axis extending in the vehicle width direction. A protector 41 is provided. As shown in FIG. 2, the wire harness 2 is curved so that the lowest point is the portion E near the lower end 52a of the door trim 52, and the portion beyond the E portion is drawn between the door panel 51 and the door trim 52 to be on the door side. It is supported by unit 4.

The wire harness 2 includes a plurality of electric wires 21 (shown in FIG. 1 and not shown in FIG. 2), a corrugated tube 22 as a “protective tube” for protecting the electric wires 21, and a A curving restricting member 6 that is inserted to restrict curving of the corrugated tube 22 is provided. Note that the corrugated tube 22 is a well-known one formed in a bellows cylindrical shape, but the bellows shape (uneven shape) is omitted in FIGS.

The curving restricting member 6 is made of synthetic resin, and as shown in FIGS. and a plurality of piece portions 65a to 65f standing upright from the ends of the connecting portion 63 in the width direction and arranged in the longitudinal direction of the connecting portion 63. As shown in FIG. Further, in the bending regulating member 6 of this example, piece portions 65a to 65f are erected from both ends of the connecting portion 63 in the width direction. The electric wire 21 is positioned between the piece portions 65a to 65f of the connecting portion 63 facing each other in the width direction. Each of the pieces 65a to 65f includes a substantially rectangular plate-like plate portion 67 and a neck portion 66 connecting the plate portion 67 and the connecting portion 63 together. Further, the end of the curving regulating member 6 opposite to the base portion 61 is positioned in front of the door-side unit 4 as shown in FIG. 2 and is a free end.

The bending regulating member 6 can be bent by elastic deformation of the connecting portion 63 in the direction in which the connecting portion 63 is inside and the piece portions 65a to 65f are outside. Bending is restricted by abutting each other. That is, the bending restricting member 6 can be bent downwardly by elastic deformation of the connecting portion 63 in the orientation shown in FIG. In the opposite direction, the adjacent piece portions 65a to 65f are brought into contact with each other to restrict upwardly convex curving. Further, as shown in FIG. 3, with the connecting portion 63 extending straight, the angle between the surfaces of the adjacent piece portions 65a to 65f that face each other, the angle near the end portion on the side of the sliding door 5 is: It is larger than the said angle of other parts.

Specifically, when the connecting portion 63 extends straight, the angle θ1 between the mutually facing surfaces of the base portion 61 and the piece portion 65a and the angle between the mutually facing surfaces of the adjacent piece portions 65a to 65c are determined. The angle θ1 is approximately 0 degrees, and the angles θ2, θ3, and θ4 between the mutually facing surfaces of the adjacent pieces 65c to 65f near the end on the sliding door 5 side are larger than θ1. In this example, θ2 is approximately 4 degrees, θ3 is approximately 5 degrees, and θ4 is approximately 6 degrees. As a result, when the base portion 61 and the piece portions 65a to 65f are in contact with each other as shown in FIG. deviate from the straight line. In the present invention, the number of pieces and the values of θ1, θ2, θ3, and θ4 can be changed as appropriate.

When the slide door 5 is half-opened as shown in FIG. 2, the bending regulating member 6 has the connecting portion 63 positioned on the upper side and the piece portions 65a to 65f positioned on the lower side. Further, when the slide door 5 is half-opened as shown in FIG. 2, the vicinity of the end portion (near the piece portions 65d to 65f) of the curving regulating member 6 on the side of the slide door 5 is curved to be more convex upward than the other portions. Great tolerance. As a result, the base portion 61 and the piece portions 65a to 65c are positioned on a straight line, and the piece portions 65d to 65f are positioned below the straight line. That is, the vicinity of the end portion of the curving regulating member 6 on the slide door 5 side is gently curved downward.

The power supply device 1 secures the necessary gap S between the wire harness 2 and the weather strip 9 as shown in FIG. In addition, since the vicinity of the end portion of the curving regulating member 6 on the slide door 5 side is gently bent downward, the lower end 52a of the door trim 52 and the wire harness 2 are lower than the conventional product (FIG. 5). They are in contact with contact pressure. As a result, the wire harness 2 can be smoothly operated when the slide door 5 is opened and closed. Further, since the friction between the lower end 52a of the door trim 52 and the corrugated tube 22 is smaller than that of the conventional product (FIG. 5), the durability of the corrugated tube 22 can be improved.

Also, in the above-described embodiment, the lower end 52a of the door trim 52 and the wire harness 2 are in contact with each other, but in the present invention, the lower end 52a of the door trim 52 and the wire harness 2 may be spaced apart.

In the above-described embodiment, the angles θ2, θ3, and θ4 between the opposing surfaces of the piece portions 65c to 65f are made larger than the angle θ1 between the opposing surfaces of the piece portions 65a to 65c. The bending tolerance is increased near the end of the bending regulating member 6 on the slide door 5 side. In addition to this, in the present invention, the distance between the pieces 65c to 65f is made larger than the distance between the pieces 65a to 65c in a state where the connection portion 63 extends straight. The bending tolerance near the end on the 5 side may be increased.

In addition, the above-described embodiment merely shows a typical form of the present invention, and the present invention is not limited to this embodiment. That is, various modifications can be made without departing from the gist of the present invention. As long as such modifications still have the configuration of the present invention, they are, of course, included in the scope of the present invention.
