Abstract

A vehicle power unit room structure is provided including a motor that is disposed inside a power unit room and that is configured to transmit drive force to a drive wheel, a compressor that is disposed adjacent to the motor in a vehicle width direction so as to overlap with the motor as viewed along the vehicle width direction, and a power supply section that is configured to supply power supplied from a power source to the motor and the compressor, and that is disposed at a vehicle upper side of the compressor so as to overlap with the compressor as viewed along a vehicle vertical direction.

First claim

What is claimed is:

1. A vehicle power unit room structure comprising:
a motor that is disposed inside a power unit room and that is configured to transmit drive force to a drive wheel;
a compressor that is disposed adjacent to the motor in a vehicle width direction so as to overlap with the motor as viewed along the vehicle width direction; and
a power supply section that is configured to supply power from a power source to the motor and the compressor, and that is disposed at a vehicle upper side of the compressor so as to overlap with the compressor as viewed along a vehicle vertical direction,
wherein
the power supply section is attached to an attachment portion provided at at least one of a pair of side members,
the attachment portion is a cross member spanning between the pair of side members in the vehicle width direction,
each of the pair of side members is provided with a shaft that projects toward a vehicle width direction inner side and that is used in attachment of the cross member, and
the cross member is provided with an insertion location through which the shafts are inserted in an axial direction of the shafts, and a fuse portion provided adjacent to the insertion location and configured to undergo plastic deformation so as to permit relative displacement in a vehicle front-rear direction between the shafts and the insertion location in a case in which a load of a predetermined value or greater toward a vehicle rear side acts on the attachment portion.

2. The vehicle power unit room structure of claim 1 , wherein the compressor is attached to the motor either directly or indirectly.

3. The vehicle power unit room structure of claim 1 , wherein the compressor is disposed at the vehicle width direction inner side of one of the pair of side members, which extends along the vehicle front-rear direction, such that there is spacing in the vehicle width direction between the compressor and the one of the pair of side members.

4. The vehicle power unit room structure of claim 1 , wherein the compressor is disposed at a position that does not overlap with one of the pair of side members, which extends along the vehicle front-rear direction, as viewed along the vehicle vertical direction.

5. The vehicle power unit room structure of claim 1 , wherein the attachment portion is a bracket attached to the at least one of the pair of side members.
