Description

  The present invention relates to an improvement in a power feeding device for feeding power to a door glass lifting motor or the like of a vehicle sliding door.

In recent years, with the expansion of the use of van type vehicles as RV vehicles, it has become necessary to supply power from the vehicle body side to the door glass lift motor and limit switch provided on the slide door in order to automate the door glass lift. Yes. Therefore, a method of connecting a flexible flat cable (hereinafter simply referred to as “flat cable”) that is curved and deformed to the body side and the door side has been considered (see Patent Document 1). However, since it is necessary to provide this flat cable on the body side, it is necessary to secure a storage space for the flat cable on the body panel or to provide a cover for shielding the flat cable from muddy water etc. The problem is that the structure is complicated and the cost is greatly increased. Therefore, as a power supply device for a vehicle sliding door that does not cause a significant increase in cost due to the complicated shape of the body panel, a guide member that is provided on the sliding door and extends in the door opening / closing direction, and a relative to the guide member. A slider held so as to be movable, a power supply line extending from the vehicle body side to the electrical components in the slide door via the slider, and one end coupled to the slider and the other end coupled to the vehicle body And a first support member elastically curved and deformable to support the power supply line, and the relative relationship between the vehicle body side fixing point and the slider side fixing point of the first support member when the sliding door is opened and closed. An apparatus has been developed that absorbs the change in the distance by the curved deformation of the first support member (see Patent Document 2).

  Even if the device disclosed in Patent Document 2 can prevent the shape of the body panel from becoming complicated, the power feeding device itself accommodates the flat cable in the guide rail, so that the flat cable is curved and deformed in this space. In addition, the power supply line support member also requires a space for bending deformation, and the device itself has a large number of parts and has not been so simple.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply device for a vehicle sliding door that has a simple structure and can absorb the relative displacement between the sliding door and the vehicle body.

  In order to achieve the above-described object, the present invention provides a power supply line that is connected to a wire harness connected to a power source on the vehicle body side and supplies power to equipment inside the slide door, and is guided to the vehicle body side along the sliding direction of the slide door. A shaft is provided, the power supply wire is wound around the guide shaft, and the coiled power supply wire is configured to be extendable.

  According to the present invention, a power supply line connected to a wire harness connected to a power source is provided on the vehicle body side to supply power to equipment inside the slide door, and a guide shaft is provided on the vehicle body side along the sliding direction of the slide door. Since the power supply wire is wound around the shaft and the coiled power supply wire is configured to be extendable and contractible, the structure of the power supply device itself becomes very simple and can be provided at low cost. Further, since the power supply line is coiled and expandable, the power supply line is loosened when the sliding door is opened and closed, and the distance between the door and the vehicle body can be absorbed. Furthermore, the coil-shaped power supply line is simply wound around the guide shaft, and the attachment is facilitated.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic plan view of a state in which the sliding door 1 is opened. A wire harness 3 connected to a power source such as a battery is wired on the vehicle body 2 side. A power line 5 is connected to a connector 4 of the wire harness 3. Connector 6 is connected. The power supply line 5 is connected to a wire harness (not shown) connected to various devices inside the slide door 1. In addition, the power supply line 5 is disposed below the passenger compartment floor of the vehicle and is protected by a protector 7. A guide shaft 8 is provided in the space below the floor along the sliding direction of the sliding door 1. A power supply line 5 is wound around the guide shaft 8, and the coil-shaped power supply line 5 is configured to be extendable and retractable like a curl cord of a telephone handset. The other end side opposite to one end side of the power supply line 5 connected to the wire harness 3 feeds power to various devices (not shown) in the slide door 1 through the inside of the arm 9 and the slider 10 of the slide door 1. It is wired to do.

  FIG. 2 shows a state in which the slide door 1 is closed, and the power supply line 5 is extended along the guide shaft 8. In this extended state, a force for returning the power supply line 5 is applied. In the vicinity of the slider 10 on the slide door 1 side, an opening is provided to allow the feeder 5 to be exposed from below the floor and to move together with the slider 10.

  3 and 4 show in detail the relationship between the guide shaft 8 and the power supply line 5 when the slide door 1 is opened and closed, that is, the state of expansion and contraction of the coil-shaped power supply line 5.

  FIG. 5 shows a cross section of the feeder 5, a tension cable 5 </ b> A is provided at the center, an electric wire 5 </ b> B is arranged around the tension cable 5 </ b> A, and the whole is covered with an insulating coating layer 5 </ b> C. The tension cable 5A reduces the power supply line 5 in a coil shape.

  In the above-described embodiment, it has been described that the power window is operated by supplying power to the device (electrical component) provided inside the slide door 1, but a sensor is provided between the slide door 1 and the vehicle body 2. Of course, it is also possible to exchange electric signals such as signals via the feeder line 5.

A schematic plan view of the sliding door opened. The schematic plan view of the state which closed the sliding door. The enlarged view of the feeder line and guide shaft of an open state. FIG. 3 is an enlarged view of a feeder line and a guide shaft in a closed state. Sectional drawing of a feeder wire.
