[Prior art]

 FIG. 6 is an explanatory diagram of a power supply mechanism using a junction switch of the related art. The conventional power feeding mechanism supplies electric power to the electrical components mounted on the slide door 1 from the body 2 side, so that the junction switch 15 is provided between the body 2 and the slide door 1 so that the electric circuit is provided only when the slide door 1 is closed. Closed contact type. In addition, there is a power supply mechanism that employs a door lock junction that takes advantage of the fact that it does not operate when the door is half open or open.

However, there is a drawback that the sliding door 1 is inferior in usability because it can be operated only when the door is closed even if an electric component such as a lighting or a power window is attached. Therefore, as shown in Japanese Utility Model Laid-Open No. 63-947, an operation switch group and a power source on the body side are connected to a wiring structure for operating electrical components provided on the slide door regardless of whether the slide door is opened or closed. A retractor that winds up the end of a long harness and a lead wire that electrically connects the operation switch group and the harness via the retractor are incorporated in the slide door, and the harness is retracted as the slide door opens and closes. A wiring structure for a sliding door that is rolled up and rolled back is disclosed.

[0004]

[Problems to be solved]

 However, since the sliding door wiring structure described above, which can always use the electrical components mounted on the sliding door for vehicles, has a limit in increasing the retractor winding diameter, the harness is retracted each time the sliding door is opened and closed. Rewinding and unwinding by means of repeatedly applying a bending and unwinding force to the harness. As a result, the durability of the harness is poor due to problems such as damage to the harness coating and wire breakage due to fatigue over time. In addition, a retractor with a complicated structure is required as a dedicated wiring component. In order to solve the above problems, the present invention is not limited to the opening and closing of the sliding door, but electrical components can always be used, and the mechanical precision can be ensured by the dedicated parts that are simply configured, and the opening and closing parts and contact parts can be provided between the electric circuits. An object of the present invention is to provide a low-priced slide power supply mechanism with good durability that is electrically connected without being provided.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 to 4 of the accompanying drawings. The slide door power supply mechanism of the present invention is a power supply mechanism by a normally closed circuit that is electrically connected without providing an opening / closing part between the electric paths of the slide door 1 and the body 2. In FIG. 2, the outer surface of the slide door 1 is the outer surface of the body 2. The position where the power feeding mechanism is attached is closed at a position corresponding to. FIG. 3 is a cross-sectional view of the attachment portion AA of FIG. As shown in FIGS. 1 and 3, the upper rail 3 having a curved tip portion restrains the position where the slide door 1 moves, is provided along the upper edge portion of the opening of the body 2, and extends along the vehicle outer direction. Be attached.

The upper roller stay 16 is fixed to the slide door 1 and protrudes toward the inside of the vehicle, and is vertically provided with an upper roller 7 that engages with the upper rail 3. The upper roller 7 moves while rotating the upper rail 3 to move the mechanism. The accuracy is secured. The shoe 6 which moves up and down is vertically provided on the upper roller stay 16 via a bush 8, and is arranged in the case 4 so as to move in a gap groove 19 provided on the outer wall of the lower part of the case 4 as the slide door 1 is opened and closed. Has been done. The folding portion of the flexible electric wire 5 is stored in the case 4 so as to be movable together with the shoe 6 as the slide door 1 is opened and closed. The flexible electric wire 5 is an electric wire in which a support member 13 having a plate strip and an insulated electric wire 14 are integrally formed in a thin strip shape as shown in FIG. 4. One end of the flexible electric wire 5 is connected to the body-side harness 9 and the folding radius is restricted to the inner diameter of the case 4. After forming the folded portion, the other end is connected to the door side harness 10 at the shoe 6.

As described above, the flexible electric wire 5 shown in FIG. 4 is a thin strip-shaped member integrally formed with the support member 13 of the plate strip by arranging one or more insulating coated wires 14 in parallel at equal intervals. It is a flexible electric wire having a double insulation structure for the conductor insulation of the insulation-coated electric wire 14 and having mechanical durability and electric insulation. When the folded portion is formed by supporting both ends of the flexible electric wire 5 having ridgedness, the inner side on the electric wire side, and the outer side on the plate ridge supporting member 13, a slight difference in inside and outside of the half radius of curvature of the folded portion Since the cross-sectional shape is curved inward, there is an advantage that the restoring force of the bending elasticity of the bending or folded portion and the spring force of the support member 13 act to prevent buckling.

In the door-side fixing portion 12 of the shoe 6, the door-side harness 10 connected to the electrical equipment mounted on the slide door 1 and one end of the flexible electric wire 5 are connected and fixed. The door side harness 10 is wired from the door side fixing portion 12 of the shoe 6 through the gap groove 19 of the case 4 to the upper roller stay 16 to prevent damage and loosely entangled with a holding member (not shown). On the other hand, at the body side fixing portion 11 at the front end of the vehicle in the case 4, the body side harness 9 connected to the power supply circuit on the body 2 side and the other end of the flexible electric wire 5 are connected and fixed. Similarly to the door harness 10, the body harness 9 is also wired to prevent damage.

In the slide door power feeding mechanism of the present invention described above, the shoe 6 provided on the upper roller stay 16 is arranged in the case 4, and one end of the flexible electric wire 5 is the body side fixing portion 11 of the case 4 and the body side harness. 9 is connected to the door side harness 10 by the door side fixing portion 12 of the shoe 6 and is connected to the door side harness 10 to be provided along the upper rail 3 to connect the case 4 to the upper rail 3 and the upper roller stay. By attaching the shoe 6 to the 16, the mechanical position accuracy of the power feeding mechanism can be easily secured, and the mechanism has high stability and durability.

Further, the above-described power feeding mechanism that utilizes the movement of the upper roller stay 16 of the opening / closing device for the slide door 1 is a component rather than a wiring mechanism configured by a retractor or the like, which is a dedicated component, as disclosed in Japanese Utility Model Laid-Open No. 63-947. The number of points can be kept small, and an inexpensive power feeding mechanism can be provided by using simple dedicated parts such as the case 4, the flexible electric wire 5, and the shoe 6.

The operation of the slide door power supply mechanism will be described below. When the slide door 1 is shaken out of the body 2, the flexible electric wire 5 subordinate to the shoe 6 moves with the shoe 6 in the case 4 as the slide door 1 opens and closes. The shoe 6 moves horizontally in the case 4 while moving up and down in the bush 8 in order to absorb the displacement of the vertical component of the vibration due to the movement of the folded portion of the flexible electric wire 5. When the sliding door 1 is further moved, the flexible electric wire 5 moves the position of the folded back portion, and the portion between the folded back portion and the body side fixed portion 11 and the door side fixed portion 12 at the fixed end is self-held in a straight line state. It smoothly moves in Case 4, and the following approximate relationship holds. X + Y = AX: The length from the folded portion to the body side fixed portion 11. Y: Length from the folded-back portion to the door-side fixed portion 12. A: constant. However, X> 0, Y> 0, and A are determined by the length of the case 4.

The diameter of the folded portion of the flexible electric wire 5 is limited to the inner diameter of the case 4, and a linear state is self-maintained along the inner wall surface of the case 4 from the folded portion to the fixed end by the action of the plate spring and the action of the shoe 6. Therefore, there is no buckling and there is no damage due to fatigue while the bending load can be reduced. In this way, the spring force of the flexible electric wire 5 and the action of the shoe 6 stabilize the movement of the shoe 6 and the flexible electric wire 5 in the case 4 because the shoe 6 moves up and down in order to keep the flexible electric wire 5 in a stable state. By constantly electrically connecting the sliding door 1 and the body 2, electric power is supplied to the electrical equipment such as the power window and the illuminator installed in the sliding door 1, and the electrical equipment is used even when the sliding door 1 is open. Is possible.

As another embodiment of the present invention, FIG. 5 is a perspective view of a slide door power feeding mechanism using a magnet 18. As shown in the figure, a case 4 formed of a synthetic resin material along the upper rail 3, a flexible electric wire 5 having one end connected to a body side fixing portion 11 on the front side of the vehicle of the case 4, and a flexible electric wire 5 A slide door power supply mechanism including a shoe 6 connected to the other end and moving in a gap groove 19 in the case 4, and a strip-shaped guide plate 17 for horizontally attaching a magnet 18 to the inner surface of the case 4 in the longitudinal direction. The flexible electric wire 5 has a plate-shaped support member 13 mounted on the surface facing the guide plate 17.

When the shoe 6 moves in the opening direction of the slide door 1, the flexible wire 5 is sequentially moved from the body side fixed portion 11 in the case 4 to the folded portion moved by the attraction force of the guide plate 17 of the magnet 18. It is adsorbed along the guide plate 17. When the slide door 1 moves in the closing direction, the attracted flexible electric wire 5 is peeled off in order by the moving folding portion by the moving pulling force of the shoe 6, and can be attached / detached by the opening / closing movement of the slide door 1. On the other hand, the flexible electric wire 5 from the shoe 6 to the folded-back portion is self-maintained in a straight line state by the spring force.
