Japanese Patent Application Publication No. 2016-136811

Various devices and equipment other than the power supply device are arranged on the vehicle floor, and these are covered with a floor carpet. Further, a resin finish plate (cover member) may be provided on the peripheral edge of the vehicle floor. A load may be applied to such a finish plate when it is stepped on by a passenger or when luggage is placed on it. Therefore, in order to make the finish plate less likely to bend when a load is applied, a configuration may be considered in which a support member is provided on the vehicle floor to support the end of the finish plate from below.

Around the power supply device for supplying power to the slide body, not only a wire harness pulled out from the case and directed to the slide body, but also a wire harness connected to the on-vehicle power source and directed to the case is routed. However, if a support member that supports the finish plate is provided around the power supply device as described above, it will easily interfere with peripheral objects such as wire harnesses and other equipment placed outside the case. This may make it difficult to use the space.

An object of the present invention is to provide a power supply device that can make it easier to use the space outside the case.

A power feeding device of the present invention is a power feeding device that is installed on a vehicle floor and supplies power to a sliding body, and includes a case that accommodates a wire harness for feeding power to the sliding body, and the case is installed on a vehicle floor. It is characterized by having a support part located below the end part of the cover member covering the upper surface and supporting the end part.

According to such a power supply device of the present invention, the end portion of the cover member is supported by the support portion provided in the case, so there is no need to arrange a separate support member on the vehicle floor. Therefore, the space outside the case and below the support part can be easily utilized, and for example, the wire harness can be easily routed outside the case.

The power supply device 1 of this embodiment is a power supply device that is provided on a vehicle floor and supplies power to a sliding seat as a sliding body, and as shown in FIG. , and a second wire harness. In this embodiment, the longitudinal direction of the vehicle is defined as the X direction, the width direction is defined as the Y direction, and the vertical direction is defined as the Z direction.

A power supply device 1 is provided on the vehicle floor, a plurality of wire harnesses are routed at appropriate positions, and a floor carpet 6 (see FIG. 2) is provided to cover these wire harnesses and the case 2 from above. . Further, a finish plate 4 as a cover member is provided on the rear side with respect to the power supply device 1, and the finish plate 4 covers the upper surface of the vehicle floor (the upper surface of the floor panel).

The finish plate 4 is made of resin, for example, and is formed to extend from the rear opening of the vehicle toward the front side. The finish plate 4 has a rear end portion fixed to the floor panel, and has an overall shape that extends upward as it goes toward the front side. Thereby, the front end portion 41 of the finish plate 4 is spaced apart from the upper surface of the floor panel. Further, the front end portion 41 is bent downward.

The case 2 is for accommodating the second wire harness, is made of resin, for example, and has a flat shape along the XY plane and with the X direction as the longitudinal direction. That is, the case 2 includes a bottom plate part 21 along the XY plane, a side part 22 standing upright from the bottom plate part 21, and an upper plate part spaced apart above the bottom plate part 21 and along the XY plane. 23. A space surrounded by the bottom plate part 21, the side part 22, and the top plate part 23 becomes an accommodation space (see FIGS. 2 and 3) 2A that accommodates the second wire harness. In addition, the bottom plate part 21 and the side part 22 may be formed integrally, the side part 22 and the top plate part 23 may be formed integrally, or all three may be formed separately. You can leave it there.

The first wire harness 3 has one end electrically connected to a power source of the vehicle, and the other end connected to the case 2. That is, the connector provided at the other end of the first wire harness 3 and the connector provided in the case 2 are fitted together. The second wire harness is housed in the case 2, and has one end electrically connected to the first wire harness 3 and the other end electrically connected to the electrical components in the slide sheet. Ru.

A rail 5 extending along the X direction is provided at a position adjacent to the case 2 in the Y direction. The rail 5 guides the slide sheet along the X direction, and also guides the holding member that holds the other end of the second wire harness along the X direction. In this manner, when the holding member moves along the X direction, the second wire harness is appropriately pulled out from the case 2 depending on the sliding position.

Here, the shape and positional relationship of the main parts of the power supply device 1 will be explained with reference to FIGS. 2 and 3 as well. The upper plate portion 23 of the case 2 is extended so as to protrude rearward in the X direction from the side surface portion 22, and this extended portion becomes a support portion 231. That is, the support portion 231 is formed integrally with the upper plate portion 23. Furthermore, the support portion 231 extends so as to cover at least a portion of the first wire harness 3 from above in the Z direction.

A plurality of ribs 232 for reinforcing the support portion 231 are formed on the upper plate portion 23 . The rib 232 extends along the ZX plane and is formed in a triangular shape when viewed from the Y direction so as to connect the tip of the support portion 231 and the side surface portion 22. That is, the rib 232 is substantially orthogonal to the support portion 231 extending along the XY plane, and substantially orthogonal to the side surface portion 22 extending along the YZ plane. Although only one rib 232 is shown in FIG. 2, a plurality of ribs 232 are provided so as to be lined up in the Y direction.

The upper surface of the upper plate part 23 is covered with a floor carpet 6. Although FIG. 2 shows an example in which two floor carpets 6 are provided, the number of floor carpets may be one, three or more, and multiple floors of different types may be provided. Carpets may be stacked. An end edge 61 of the floor carpet 6 on the rear side in the X direction is covered by the finish plate 4 from above in the Z direction, and the front end 41 of the finish plate 4 abuts against the floor carpet 6.

At this time, a support portion 231 is provided on the lower side in the Z direction with respect to the front end portion 41 with the floor carpet 6 interposed therebetween. That is, the support portion 231 is located below the front end portion 41 of the finish plate 4 and supports the front end portion 41 from below via the floor carpet 6. Thereby, when a load is applied to the finish plate 4 from above in the Z direction, this load can be received by the support portion 231, and deformation of the finish plate 4 is suppressed.

Further, a wire harness storage space S1 is formed between the vehicle floor and the floor carpet 6 on the lower side of the horizontal portion 42 of the finish plate 4 that extends along the XY plane continuously from the front end portion 41. . The first wire harness 3 is routed so as to pass through the wire harness accommodation space S1.

According to this embodiment, the following effects are achieved. That is, by supporting the front end portion 41 of the finish plate 4 by the support portion 231 provided on the case 2, there is no need to arrange a separate support member on the vehicle floor. Therefore, the space outside the case 2 and below the support portion 231 (wire harness storage space S1) can be effectively used, and the first wire harness 3 can be easily routed outside the case 2.

In addition, since the support part 231 is formed integrally with the upper plate part 23 of the case 2, it is possible to arrange a separate support member on the vehicle floor, or to install a support part separate from the upper plate part in the case. The number of parts can be reduced compared to the configuration provided in

Further, in the case 2, the upper plate portion 23 is extended to protrude from the side surface portion 22 to form the support portion 231, so that the front end portion 41 can be easily extended without extending the finish plate 4 forward in the X direction. There is no need to change the shape of the finish plate 4.

Note that the present invention is not limited to the embodiments described above, and includes other configurations that can achieve the object of the present invention, and the present invention also includes the following modifications.

For example, in the embodiment described above, the support portion 231 is formed integrally with the upper plate portion 23 of the case 2, but a support portion separate from the upper plate portion may be provided. For example, if a separate support section is fixed (attached) to a conventionally shaped case, the conventionally shaped case can be used.

Further, in the above embodiment, the upper plate part 23 of the case 2 is extended to protrude from the side surface part 22 to form the support part 231, but the support part does not need to protrude from the side face part. good. That is, if the front end portion 41 is located above the upper plate of the case by extending the finish plate 4 forward in the X direction or by extending the entire case backward in the The plate portion may function as a support portion.

Further, in the embodiment described above, the front end portion 41 of the finish plate 4 as a cover member is supported by the support portion 231 of the case 2, but the present invention is not limited to such a configuration. That is, when the cover members are arranged so as to be lined up in the Y direction with respect to the case 2, the end of the cover member in the Y direction may be supported by the support part, or the end of the cover member in the Y direction may be supported by the support part, or When the cover members are arranged side by side, the rear end portion of the cover member may be supported by the support portion.
