[0022] Hereinafter, an embodiment of the present application will be described based on the drawings.

[0023] Figure 1 The wiring harness routing structure of the charging vehicle of the embodiment is shown. As the charging vehicle, an electric vehicle is exemplified. Figure 1 With respect to Figure 2 , a part of the vehicle body member such as the floor panel 3 of the vehicle body 1 is omitted, whereby the battery unit 5 arranged on the lower side of the floor panel 3 can be seen. The battery unit 5 is constituted by a battery mounted on the vehicle. Hereinafter, the battery unit 5 will be sometimes simply referred to as the battery 5. Note that the directions indicated by arrows FR, UP, and LH in the drawing are the front direction of the vehicle, the upper direction of the vehicle, and the left direction of the vehicle, respectively.

[0024] As shown in Figure 2 , a front dash panel 9 is provided on the front side of the floor panel 3. The front dash panel 9 is provided on the front side of the passenger compartment 11 and is a partition wall that separates the passenger compartment 11 from a front motor room 13. A front side frame 15 extends in the vehicle front-rear direction on both sides in the vehicle width direction of the lower portion of the motor room 13. The lower portion of the front dash panel 9 is inclined toward the rear. The rear portion of the front side frame 15 is bent downward along the above-mentioned inclined portion of the front dash panel 9, and the bent portion is continuous with the above-mentioned inclined portion of the front dash panel 9.

[0025] ​​​​A roof ridge panel 17 as a side portion of the vehicle body is provided above the front longitudinal beam 15 of the motor room 13 and slightly outward in the vehicle width direction. A rear portion of the roof ridge panel 17 is connected to a front pillar 19 extending in the up-down direction. A support tower 21 and a wheel cover panel 23 are provided inward in the vehicle width direction of the roof ridge panel 17. A front portion of the support tower 21 and a rear portion of the wheel cover panel 23 are connected to each other. Upper portions of the support tower 21 and the wheel cover panel 23 are connected to the roof ridge panel 17, and lower portions thereof are connected to the front longitudinal beam 15.

[0026] The roof ridge panel 17 has a front portion 25 located forward from the vicinity of the support tower 21, and a rear portion 27 located rearward from the vicinity of the support tower 21. As shown in Figure 4 , the front portion 25 extends long in the front-rear direction, and the rear portion 27 extends wide in the up-down direction from a rear end of the front portion 25 and is connected to the front pillar 19. The roof ridge panel 17 has a side surface 29, an upper surface 31, and a lower surface 33 over the entire length including the front portion 25 and the rear portion 27. As shown in Figure 5 , the roof ridge panel 17 has an outer panel 17a and an inner panel 17b, which are joined to each other by upper and lower flange joints F1, F2 to form a closed sectional shape. The side surface 29, the upper surface 31, and the lower surface 33 are formed in the outer panel 17a.

[0027] As shown in Figure 4 , a front portion upper surface 31a and a front portion lower surface 33a of the front portion 25 are horizontal surfaces parallel to each other. A rear portion upper surface 31b of the rear portion 27 is inclined so that the height in the up-down direction gradually increases toward the rear from the side of the front portion 25. A rear portion lower surface 33b of the rear portion 27 is inclined so that the height in the up-down direction gradually decreases toward the rear from the side of the front portion 25, and the portion on the side of the front pillar 19 is gently curved convex downward.

[0028] A charging port mounting portion 35 is provided in the side surface 29 between the curved portions of the rear portion upper surface 31b and the rear portion lower surface 33b. A charging port 37 shown in Figure 1 , Figure 5 is mounted to the charging port mounting portion 35. The charging port 37 is used to charge the storage battery 5. The charging port mounting portion 35 has a through-hole 39 penetrating the side surface 29, and a bracket 41 provided on the outer side in the vehicle width direction of the side surface 29 and on the periphery of the through-hole 39. The bracket 41 can be integral with the side surface 29 or separate from the side surface 29.

[0029] The through-hole 39 has an upper edge 39a extending straight in the front-rear direction, a pair of front and rear side edges 39b extending straight downward from both ends of the upper edge 39a in the front-rear direction, and a lower edge 39c connecting the lower ends of the pair of front and rear side edges 39b to each other. The lower edge 39c is curved convex downward. The brackets 41 are provided along the pair of front and rear side edges 39b, respectively. As shown in Figure 4 , the pair of front and rear brackets 41 are substantially left-right symmetrical in the side view.

[0030] As shown in Figure 3 , Figure 5 , the mounting surfaces 41a on the outer sides in the vehicle width direction of the pair of front and rear brackets 41 are inclined so that the lower portions protrude more to the outer sides in the vehicle width direction than the upper portions. The pair of front and rear brackets 41 have a pair of front and rear side surfaces 41b that stand from the side surface 29. The pair of front and rear mounting surfaces 41a are curved from the end edges on the outer sides in the vehicle width direction of the pair of front and rear side surfaces 41b in directions opposite to each other. The space between the pair of front and rear brackets 41 is aligned with the through hole 39. Mounting holes 41ah are formed at two positions, upper and lower, of the pair of front and rear mounting surfaces 41a.

[0031] The charging port 37 is mounted to the charging port mounting portion 35 by being inserted into the space between the pair of front and rear brackets 41 and the through hole 39 from the outside of the vehicle body. The flange portion 37a around the charging port 37 is in abutment with the mounting surfaces 41a in a state in which the charging port 37 has been inserted into the space between the pair of front and rear brackets 41 and the through hole 39. At this time, the flange mounting holes formed in the flange portion 37a are aligned with the mounting holes 41ah, and the bolts 43 are inserted into the flange mounting holes and the mounting holes 41ah and are fastened to the nuts 45.

[0032] As shown in Figure 5 , the charging port 37, in a state in which it is mounted to the vehicle body 1, penetrates the outer panel 17a of the cover ridge panel 17 of the vehicle body side portion. That is, the charging connector connecting portion 37b on the outer side in the vehicle width direction of the charging port 37 is located on the outside of the outer panel 17a, and the wire harness connecting portion 37c on the inner side in the vehicle width direction is located on the inside of the outer panel 17a. A lid 37b1 is freely openably and closably mounted to the end portion on the outside of the vehicle body of the charging connector connecting portion 37b. In a state in which the lid 37b1 is open, a charging connector, not shown, that is drawn from a charger outside the vehicle is connected to the charging connector connecting portion 37b, and the battery 5 is charged. The wire harness connecting portion 37c is connected to one end of the wire harness 47.

[0033] As shown in Figure 5 , the wire harness connecting portion 37c of the charging port 37 mounted as described above is located between the outer panel 17a and the inner panel 17b. Therefore, the wire harness 47 penetrates the inner through hole 17bh formed in the inner panel 17b. The charging port 37, in a state in which it has penetrated the outer panel 17a of the cover ridge panel 17, is inclined so that the charging connector connecting portion 37b on the outer side in the vehicle width direction is located more on the upper side than the wire harness connecting portion 37c on the inner side in the vehicle width direction. The wire harness 47, one end of which is connected to the wire harness connecting portion 37c, is routed toward the lower portion inside the vehicle in the direction of the inclination of the charging port 37.

[0034] As shown in Figure 7As shown, a connector 49 is mounted on the other end of the wiring harness 47. On the other hand, the battery unit 5 has a battery-side connector 51 at its front end. The connector 49 of the wiring harness 47 connects to the battery-side connector 51. The front end of the battery unit 5, where the battery-side connector 51 is mounted, has a battery inclined portion 5a that is inclined downwards towards the front of the vehicle, with the lower part closer to the front than the upper part. The battery-side connector 51 is mounted on the battery inclined portion 5a. Therefore, the connection port of the battery-side connector 51 faces upwards towards the front of the vehicle. Therefore, the connector 49 of the wiring harness 47 connects to the battery-side connector 51 from the front of the vehicle towards the rearwards at a downward angle.

[0035] like Figure 8 As shown, the battery-side connector 51 is located approximately near the center of the battery unit 5 in the vehicle width direction. Another connector 53 is located to the left of the battery-side connector 51 in the vehicle width direction. A wiring harness (not shown) is connected to the connector 53 for connection to the motor side.

[0036] like Figure 6 As shown, the front bulkhead 9 has a bulge 9a that protrudes further forward from the center side of the vehicle body than the side where the charging port 37 is located. The charging port 37 is located further rearward than the bulge 9a. The wiring harness 47 is connected to the battery unit 5 at a position corresponding to the bulge 9a in the vehicle width direction, extending rearward towards the vehicle body.

[0037] The bulge 9a has a surface that is approximately right-angled with respect to the longitudinal direction of the vehicle body and approximately parallel with respect to the width direction of the vehicle. The front bulkhead 9 has a width-direction inclined portion 9c, which, relative to the bulge 9a, bends and slopes towards the rear of the vehicle body at a bend 9b on the side where the charging port 37 is located. The end of the width-direction inclined portion 9c on the opposite side of the bulge 9a engages with the inner plate 17b of the ridge plate 17. The connection portion of the width-direction inclined portion 9c relative to the ridge plate 17 is located further rearward than the charging port 37.

[0038] The charging port 37 is located in the longitudinal direction of the vehicle body, corresponding to the inclined portion 9c in the width direction. Therefore, the wiring harness 47 introduced into the vehicle from the charging port 37 is... Figure 6 In a top-down view, the inclined section 9c bends forward along the width of the vehicle body, and after passing the curved section 9b, the wiring is routed inward along the front surface of the bulge section 9a in the width of the vehicle body.

[0039] A wiring harness 47 is provided in a region S between the bulge 9a and the vehicle width inclined portion 9c near the curved portion 9b of the front bulkhead 9 and the support tower 21. The wiring harness 47 leading from the charging port 37 is routed in region S. The vehicle body component in region S has an inclined surface 55 as a vertically inclined portion. The inclined surface 55 is inclined from the charging port 37 side towards the center side in the vehicle width direction, with the vertical height gradually decreasing. The front side of the inclined surface 55 is connected to the support tower 21, and the rear side of the vehicle body is connected to the front bulkhead 9.

[0040] The tilt angle of the inclined surface 55, viewed from the front-rear direction of the vehicle body, is approximately the same as the tilt angle of the charging port 37, viewed from the front-rear direction of the vehicle body. That is, when viewed from the front-rear direction of the vehicle body, the wiring harness 47 extending from the charging port 37 runs directly and straight along the inclined surface 55, diagonally downwards, from the tilt direction of the charging port 37. For example... Figure 6 and Figure 7 As shown, the wiring harness 47 is fixed at multiple positions relative to the front bulkhead 9, along the wiring direction, by fasteners 57 (57a to 57d) at appropriate intervals.

[0041] like Figure 7 As shown, when viewed from the front of the vehicle, wiring harness 47 extends from the left side in the vehicle width direction (in... Figure 7 The wiring harness 47 is laid in a gradually downward and inclined manner from the end connected to the charging port 37 (on the right side) to the end connected to the battery unit 5. Figure 6 In the top view shown, the wire bends towards the front of the vehicle from near the end connected to the charging port 37 in the first bend 47a, and then bends inward in the vehicle width direction in the second bend 47b, with wiring running along the front surface of the bulge 9a towards the center in the vehicle width direction.

[0042] On the front surface of the bulge 9a, the third bend 47c of the wiring harness 47, near the location corresponding to the fastener 57b, bends slightly forward towards the front of the vehicle, and is routed diagonally to the right of the front of the vehicle. The wiring harness 47... Figure 6 In the top view shown, in front of the battery-side connector 51, the fourth bend 47d bends towards the rear of the vehicle at an angle of approximately 90 degrees. It should be noted that the first bend 47a, the second bend 47b, and the third bend 47c all have obtuse angles of approximately 150 degrees in the top view.

[0043] When the wiring harness 47 bends towards the rear of the vehicle at the fourth bend 47d in a top view, a bulge 9a is formed, thereby pre-bending towards the front of the vehicle at the first bend 47a and the third bend 47c. Therefore, the bending angle of the fourth bend 47d can be minimized. Wiring is routed along the inclined portion of the lower part of the front bulkhead 9 between the fourth bend 47d of the wiring harness 47 and the connector 49. The inclined portion of the lower part of the front bulkhead 9 is secured by a fastener 57d. That is, the wiring harness 47 bends diagonally downwards towards the rear of the vehicle from the fourth bend 47d towards the connector 49.

[0044] Figure 9 Compared to Figure 2 An additional body panel, namely a front wheel fender 59, is added to the vehicle body. An opening 59a is formed on the front wheel fender 59 at a position corresponding to the charging port 37. A cover 61 is provided at the opening 59a, which can be opened and closed freely. By opening the cover 61, the charging port 37 is exposed to the outside through the opening 59a. In this state, the charging connector of a charger (not shown) is connected to the charging port 37 for charging.

[0045] Wiring harness 47 is installed on the vehicle body with charging port 37 connected. At this time, the connector 49 side of wiring harness 47 is... Figure 3 , Figure 4 In this state, the connector 49 is inserted into the vehicle interior through the through hole 39 and the inner through hole 17bh of the charging port mounting part 35. At this time, the connector 49 and the wiring harness 47 are guided to slide on the inclined surface 55 of region S and inserted downwards towards the center in the vehicle width direction. During insertion, the wiring harness 47 is also pulled out from inside the vehicle. After the connector 49 and the wiring harness 47 are inserted into the vehicle interior, the charging port 37 is fixed in place by the bracket 41 of the charging port mounting part 35, and the wiring harness 47 is fixed to the vehicle body by the fixing member 57. Then, the connector 49 is connected to the battery-side connector 51 of the battery unit 5 mounted on the vehicle body.

[0046] Next, the effects of the implementation method will be explained.

[0047] This embodiment includes: a battery unit 5 mounted on a vehicle, a charging port 37 provided on a ridge plate 17 on the side of the vehicle body for charging the battery unit 5, and a wiring harness 47 connecting the battery unit 5 to the charging port 37. The front end of the wiring harness 47 connected to the charging port 37 passes through the inner plate 17b of the ridge plate 17 and is located inside the vehicle.

[0048] Therefore, the wiring harness 47 can be routed directly into the vehicle interior in a roughly straight line from the front end of the charging port 37 located inside the inner panel 17b. This improves the ease of wiring the harness 47 and allows for a shorter overall length, thereby reducing material costs.

[0049] The charging port 37 of the present embodiment is provided at a position corresponding to the motor room 13 in front of the cowl 9, and the cowl 9 has a bulging portion 9a bulging more toward the front of the vehicle body on the central side in the vehicle width direction than on the side where the charging port 37 is provided. The charging port 37 is located more toward the rear of the vehicle body than the bulging portion 9a, and the wire harness 47 is connected to the battery unit 5 from the front of the vehicle body at a position corresponding to the bulging portion 9a in the vehicle width direction.

[0050] In this case, the wire harness 47 introduced into the vehicle from the charging port 37 is temporarily displaced toward the front of the vehicle body due to the bulging portion 9a. Thus, the curvature of the fourth bent portion 47d is smaller, and the workability of routing the thick and inflexible wire harness 47 can be improved.

[0051] The cowl 9 of the present embodiment has a vehicle width direction inclined portion 9c inclined with respect to the bulging portion 9a that is substantially parallel to the vehicle width direction, in such a manner that the charging port 37 side is located toward the rear of the vehicle body. Thus, the wire harness 47 introduced into the vehicle from the charging port 37 can be gently directed toward the front of the vehicle along the vehicle width direction inclined portion 9c.

[0052] The present embodiment provides a region S in which the wire harness 47 is routed between the cowl 9 and the support tower 21 located more toward the front of the vehicle body than the cowl 9. Here, when the charging port 37 and the wire harness 47 are installed to the vehicle body, the connector 49 side of the wire harness 47 in a state connected to the charging port 37 is inserted into the vehicle interior from the through hole 39 and the inner through hole 17bh of the charging port mounting portion 35. At this time, it is difficult for the worker to see the vehicle interior from the outside of the vehicle, but since the region S is provided, the routing work of the wire harness 47 is easily performed.

[0053] The battery 5 of the present embodiment is located more toward the lower side in the vertical direction than the connection portion of the wire harness 47 to the charging port 37. The vehicle body member of the region S in which the wire harness 47 is routed is provided with an inclined surface 55 gradually decreasing in height in the vertical direction from the charging port 37 side toward the central side in the vehicle width direction. Thus, when the connector 49 side of the wire harness 47 is inserted into the vehicle interior from the through hole 39 and the inner through hole 17bh of the charging port mounting portion 35, it can be slid and pushed in on the inclined surface 55, and the routing work is easily performed.

[0054] The battery 5 of the present embodiment is located more toward the lower side in the vertical direction than the connection portion of the wire harness 47 to the charging port 37, and the portion of the battery unit 5 to which the wire harness 47 is connected is directed toward the obliquely upper side of the vehicle body. Thus, the connector 49 of the wire harness 47 can be connected to the battery side connector 51 from the obliquely lower side of the vehicle body toward the rear, and the connection work is easily performed.

[0055] Note that in the above embodiment, the charging port 37 is provided on the side of the vehicle (Japanese) left-hand side of the passenger seat. In this case, the charging port 37 is used for quick charging, and a charging port for normal charging is provided on the side of the vehicle (Japanese) right-hand side of the driver seat.

[0056] The above embodiment is merely a simple example for facilitating the understanding of the present application, and the present application is not limited to this embodiment. The technical scope of the present application is not limited to the specific technical matters disclosed in the above embodiment, and includes various modifications, alterations, alternative techniques, and the like that are easily derived therefrom.

[0057] For example, in the above embodiment, the charging port 37 is provided on the left-hand side of the vehicle, but the charging port 37 can be provided on the right-hand side of the vehicle. In this case, the driver seat is located on the left-hand side of the vehicle.
