Abstract

A high-voltage equipment component is disposed in a recessed accommodating portion which is formed on a vehicle body floor in such a manner as to be recessed downwardly. The high-voltage equipment component is accommodated in the recessed accommodating portion in a suspended state via a sub-assembly frame which is supported on the vehicle body floor. A heat insulating member for forming a flow path for allowing cooling air to flow towards the high-voltage equipment component is interposed between the high-voltage equipment component and a bottom portion of the recessed accommodating portion.

Claims

1. A structure for installing a high-voltage electrical equipment component to a vehicle, wherein the high-voltage electrical equipment component is arranged in a downwardly recessed accommodating portion formed on a vehicle body floor in a suspended state.

2. The structure according to claim 1, wherein the high-voltage equipment component is accommodated in the recessed accommodating portion in the suspended state via a sub-assembly frame which is supported on the vehicle body floor.

3. The structure according to claim 2, wherein the sub-assembly frame is connected to a reinforcement member of the vehicle body floor which is provided on an upper or lower surface of the vehicle body floor.

4. The structure according to claim 3, wherein the sub-assembly frame is connected to a lower portion of a cross member which is provided so as to extend transversely across the recessed accommodating portion.

5. The structure according to claim 2, wherein the sub-assembly frame is formed into an annular configuration which follows an interior side or an opening in the accommodating recessed portion.

6. The structure according to claim 1, wherein a heat insulating member for forming a flow path for allowing cooling air to flow towards the high-voltage equipment component is interposed between the high-voltage equipment component and a bottom portion of the recessed accommodating portion.

7. The structure according to claim 6, wherein the heat insulating member is formed of a resilient material and is pressed to be compressed and deformed by the high-voltage equipment component when the high-voltage equipment component is arranged in the recessed accommodating portion.

8. The structure according to claim 7, wherein the heat insulating member is pressed to be compressed and deformed by a connecting member which connects respective pieces of high-voltage equipment of the high-voltage equipment component together.

9. The structure according to claim 3, wherein the sub-assembly frame is formed into an annular configuration which follows an interior side of an opening in the accommodating recessed portion.

10. The structure according to claim 4, wherein the sub-assembly frame is formed into an annular configuration which follows an interior side of an opening in the accommodating recessed portion.
