Vehicle body structure
A vehicle body structure includes: a recess formed in a rear floor panel of a trunk of a vehicle; a drive power supply device that supplies power to drive the vehicle; and an auxiliary power supply device that supplies power to auxiliary machinery mounted on the vehicle, wherein the auxiliary power supply device is configured as an auxiliary power supply device structure by being fixed to a pedestal formed in the recess, and the drive power supply device is disposed side by side in a vehicle width direction with the auxiliary power supply device in the recess, and the auxiliary power supply device structure has a rear end positioned behind a rear end of the drive power supply device in a vehicle front-rear direction.
1. A vehicle body structure comprising:
a recess formed in a floor panel of a trunk of a vehicle;
a drive power supply device that supplies power to drive the vehicle; and
an auxiliary power supply device that supplies power to auxiliary machinery mounted on the vehicle, wherein
the auxiliary power supply device is configured as an auxiliary power supply device structure by being fixed to a pedestal formed in the recess, and
the drive power supply device is disposed side by side in a vehicle width direction with the auxiliary power supply device in the recess, and the auxiliary power supply device structure has a rear end positioned behind a rear end of the drive power supply device in a vehicle front-rear direction.
2. The vehicle body structure according to claim 1 , wherein the drive power supply device is supported in a suspended state by a fixing frame attached to the floor panel, and a space is formed between the drive power supply device and a bottom surface of the recess.
3. The vehicle body structure according to claim 2 , wherein
the fixing frame includes a pair of frame parts disposed so as to extend in the vehicle width direction and to be spaced apart from each other in the front-rear direction,
the auxiliary power supply device includes a pair of terminals disposed so as to be spaced apart from each other in the vehicle front-rear direction,
a front terminal of the pair of terminals is positioned between the pair of frame parts,
a rear terminal of the pair of terminals is positioned behind a rear frame part of the pair of frame parts, and
a distance between a front frame part of the pair of frame parts and the front terminal is set longer than a distance between the rear frame part and the rear terminal.
4. The vehicle body structure according to claim 3 , wherein the pair of terminals are disposed at positions overlapping with the fixing frame in a horizontal direction.
5. The vehicle body structure according to claim 2 , wherein
the auxiliary power supply device includes a pair of terminals disposed so as to be spaced apart from each other in the vehicle front-rear direction, and
the fixing frame includes a first frame part extending in the vehicle width direction between the pair of terminals and a second frame part extending forward from the first frame part on a side closer to the drive power supply device than the pair of terminals are.
6. The vehicle body structure according to claim 1 , wherein the drive power supply device is positioned on an opposite side of the auxiliary power supply device to an exhaust system.
7. The vehicle body structure according to claim 1 , wherein a cooling fan for cooling the drive power supply device is provided at a rear end of the drive power supply device.
8. The vehicle body structure according to claim 1 , wherein the recess has a contact surface that comes into contact with the auxiliary power supply device at a front end of the auxiliary power supply device.
