- the power receiving coil 22 is disposed in the center of the vehicle, the battery 27, the power receiving coil 22, and the motor unit 29U are linearly mounted in the vehicle front-rear direction, and the wire harness 31 is passed above the power receiving coil 22. It is routed in the longitudinal direction of the vehicle. For this reason, the wire harness 31 can be routed linearly in plan view, and the harness length can be shortened.
- a tunnel portion 42 is formed at the vehicle center (center in the vehicle width direction).
- the power receiving coil 22 is disposed across the lower open portion of the tunnel portion 42, and the wire harness 31 is routed along the inside of the tunnel portion 42.
- the power receiving coil 22 has a rectangular board-like rigid structure by storing the coil main body 221 between the metal protective casing 222 and the synthetic resin lid 223 described above. For this reason, the rigidity of the lower open part of the tunnel part 42 can be improved, and the expansion deformation (mouth opening) prevention function of the tunnel part 42 can be exhibited.
- the wire harness 31 can be stored in the closed state formed by the power receiving coil 22 and the tunnel portion 42, the safety of the wire harness 31 can be further improved.
- the power receiving coil 22 has a junction box 225 on the upper surface thereof.
- the power receiving coil 22 is disposed across the lower open portion of the tunnel portion 42 as described above, and the junction box 225 is disposed in the tunnel portion 42. For this reason, the security of the junction box 225 can be improved.
- junction box 225 protruding from the upper surface of the power receiving coil 22 is disposed in the tunnel portion 42. For this reason, since it can suppress that the ground height of the floor panel 40 becomes large, modeling of a vehicle body can be performed advantageously on design.
- the junction box 225 is formed separately from the power receiving coil 22 and is detachably attached to the upper surface of the power receiving coil 22. For this reason, it is also possible to remove the junction box 225 according to the specification and mount it in the vehicle interior shown in FIG. Thereby, especially in the hybrid vehicle specification, the exhaust pipe can be arranged vertically in the tunnel portion 42, and the vehicle body lower structure can be shared.
- the tunnel part 42 is provided with a through hole 47 on its top wall. For this reason, it is possible to route the wire harness 32 and the like that transmit power from the battery 27 or the junction box 225 to the indoor auxiliary device 60 mounted in the passenger compartment 1R, and to increase the degree of freedom of the routing layout. Can do.
- the tunnel portion 42 includes a stiffening portion 43 having a closed cross section that extends in the vehicle front-rear direction along the bulging bases on both sides, and the power receiving coil 22 is mounted across the stiffening portion 43. For this reason, both the attachment rigidity of the power receiving coil 22 and the vehicle width direction rigidity of the lower open part of the tunnel part 42 can be enhanced.
- the vehicle width direction dimension W2 of the power receiving coil 22 is set larger than the width dimension W1 of the lower open portion of the tunnel portion 42, and the power receiving coil 22 is directly coupled to the stiffening portions 43 on both sides of the open portion. For this reason, the attachment rigidity of the above-mentioned receiving coil 22 and the vehicle width direction rigidity of the tunnel part 42 can be improved further.
- the motor unit 29U is mounted on a subframe 51 which is a skeleton member arranged on the lower side of the front compartment 1F.
- the rear end portion of the sub-frame 51 is provided with an extension portion 53 that extends rearward from both sides of the power receiving coil 22 in the vehicle width direction and stiffens a fixed portion of the power receiving coil 22.
- the fixed portion of the power receiving coil 22 is stiffened by the extension portion 53, and the mounting rigidity of the power receiving coil 22 can be increased against the vibration input that acts on the fixed portion due to vibration during traveling or the like. Further, the front side and both left and right sides of the power receiving coil 22 are guarded by the rear end portion of the subframe 51 and the extension portions 53 on both sides thereof, and the rear side of the power receiving coil 22 is guarded by the battery 27.
- the power receiving coil 22 can be protected from road surface interference and the like, and the protective effect of the wire harness 32 arranged above can be enhanced.
- the case where the relationship between the vehicle width direction dimension W2 of the power receiving coil 22 and the width dimension W1 of the lower open portion of the tunnel portion 42 is W1 ⁇ W2, but W1> depending on vehicle specifications. It is also possible to set W2.
- the power receiving coil 22 may be coupled across the lower open portion of the tunnel portion 42 via the bracket.
- the floor panel 40 is exemplified as having the tunnel portion 42 at the center of the vehicle.
- the floor panel 40 can be applied to a flat floor type having no tunnel portion 42.
- the power receiving unit is mounted on the lower surface of the front part of the floor panel close to the front wheel to be steered, in the center in the vehicle width direction. For this reason, according to the present invention, when the vehicle is parked at a predetermined stop position in the parking space, the power receiving unit is appropriately set with respect to the power feeding unit based on the driving sense of performing parking steering with the vehicle center aligned with the power feeding unit on the road surface side. Can be directly aligned.
- the mounting rigidity of the coil unit is increased against the vibration input that acts on the fixed portion due to vibration during running or the like.
- the front side and the left and right sides of the power receiving unit are guarded by the rear end portion of the subframe and the extension portions on both sides thereof, and the rear side of the power receiving unit is guarded by a battery mounted on the lower surface of the floor panel. be able to.
- a power receiving part can be protected from road surface interference etc., and safety
