Abstract

An installation structure includes a member 7 extending in a longitudinal direction of a vehicle and provided on the lower face of a bottom 6a of a spare tire housing 6, a charger 1 provided with fins 2 under the charger 1, the charger 1 installed in the tire housing 6, and a blower 15 for cooling the charger 1 provided in the tire housing 6, so as to lead air from the blower 15 to the fins 2; the installation structure further includes linear first and second brackets 9 and 10 disposed in parallel to each other with a distance therebetween, so as to be joined onto the upper face of the bottom 6a of the tire housing 6, wherein the charger 1 is placed on the first and second brackets 9 and 10 so as to arrange the fins 2 and the first and second brackets 9 and 10 in parallel to one another, the blower 15 is disposed in the vicinity of an aperture 14 surrounded by the first and second brackets 9 and 10 and the charger 1, and the second bracket 10 is joined together with the member 7 and the tire housing 6 to one another.

Claims

1. An installation structure for electrical equipment in a rear vehicle body, comprising:

a spare tire housing provided in a rear floor panel;

a member extending in a longitudinal direction of a vehicle and provided on a lower face of a bottom of the spare tire housing;

electrical equipment provided with fins for cooling under the electrical equipment, the electrical equipment installed in the spare tire housing; and

a blower for cooling the electrical equipment provided in the spare tire housing and configured so as to lead air from the blower to the fins for cooling at the electrical equipment,

the installation structure further comprising a linear first bracket and a linear second bracket disposed in parallel to each other with a distance therebetween, so as to be joined onto an upper face of the bottom of the spare tire housing, wherein

the electrical equipment is placed on the first bracket and the second bracket so as to arrange the fins for cooling, the first bracket and the second bracket in parallel to one another,

the blower is disposed in a vicinity of one of front and rear apertures surrounded by the first bracket, the second bracket and the electrical equipment, and

at least one of the first bracket and the second bracket is joined together with the member and the spare tire housing to one another.

2. The installation structure for electrical equipment in a rear vehicle body according to claim 1, wherein

the first bracket and the second bracket are disposed in parallel to the member, and

at least one of the first bracket and the second bracket is disposed so as to be overlapped with the member.

3. The installation structure for electrical equipment in a rear vehicle body according to claim 2, wherein

each of the first bracket, the second bracket and the member is formed to have a hat-shaped cross section with flanges on right and left sides thereof,

either flange or both flanges on the right and left sides of at least one of the first bracket and the second bracket are disposed so as to be overlapped with either flange or both flanges on the right and left sides of the member, and

the overlapped flanges are joined together with the spare tire housing in three layers to one another.

4. The installation structure for electrical equipment in a rear vehicle body according to claim 1, wherein

the first bracket and the second bracket are disposed in a direction vertical to the member, and

the first bracket and the second bracket are disposed so as to be partially overlapped with the member.

5. The installation structure for electrical equipment in a rear vehicle body according to claim 4, wherein

each of the first bracket, the second bracket and the member is formed to have a hat-shaped cross section with flanges on right and left sides thereof, and

at a position where the respective flanges of the first bracket and the second bracket are overlapped with the flanges of the member, the overlapped flanges are joined together with the spare tire housing in three layers to one another.

6. An installation structure for electrical equipment in a rear vehicle body comprising:

a spare tire housing provided in a rear floor panel;

a member extending in a longitudinal direction of a vehicle and provided on a lower face of a bottom of the spare tire housing;

electrical equipment provided with fins for cooling under the electrical equipment, the electrical equipment installed in the spare tire housing; and

a blower for cooling the electrical equipment provided in the spare tire housing and configured so as to lead air from the blower to the fins for cooling at the electrical equipment,

the installation structure further comprising a linear first bead and a linear second bead formed to project upward on an upper face of the bottom of the spare tire housing, and the first bead and the second bead provided in parallel to each other with a distance therebetween, wherein

the electrical equipment is placed on the first bead and the second bead so as to arrange the fins for cooling, the first bead and the second bead in parallel to one another,

the blower is disposed in a vicinity of one of front and rear apertures surrounded by the first bead, the second bead and the electrical equipment, and

at least one of the first bead and the second bead is disposed so as to be overlapped with the member.
