Abstract

A case structure of a power equipment unit which contains power equipment mounted in a vehicle includes: a case body which contains the power equipment and an upper portion of which is open; a lid member which covers the upper portion of the case body; and a cover member which is attached to the lid member and which covers at least an opening part formed in the lid member, wherein: an intake port for taking in air from outside is formed in the cover member; a space part is formed between the cover member and the lid member; the opening part of the lid member is surrounded by a circumferential wall having a cylindrical shape; and a drain passage communicating with a drain port is connected with an outer circumference of the circumferential wall.

Claims

1. A case structure of a power equipment unit which contains power equipment mounted in a vehicle, the case structure comprising:

a case body which contains the power equipment and an upper portion of which is open;

a lid member which covers the upper portion of the case body; and

a cover member which is attached to the lid member and which covers at least an opening part formed in the lid member, wherein;

an intake port for taking in air from outside is formed in the cover member;

a space part is formed between the cover member and the lid member;

the opening part of the lid member is surrounded by a circumferential wall having a cylindrical shape; and

a drain passage communicating with a drain port is connected with an outer circumference of the circumferential wall.

2. The case structure of the power equipment unit according to claim 1, wherein:

a recess part having an annular shape is provided in the outer circumference; and

the drain passage is connected with the recess part.

3. The case structure of the power equipment unit according to claim 2, wherein

the recess part and the drain passage are formed by concaving the lid member.

4. The case structure of the power equipment unit according to claim 1, wherein:

the intake port is provided on one surface of the vehicle in a front and rear direction; and

the drain port is provided on an other surface of the vehicle in the front and rear direction.

5. The case structure of the power equipment unit according to claim 1, wherein

the drain passage is tilted downward toward the drain port.

6. The case structure of the power equipment unit according to claim 1, wherein:

in the cover member, a partition wall part is provided between the intake port and the opening part to extend downward from an upper wall; and

a lower end of the partition wall part is positioned below an upper end of the opening part and below a lower end of the intake port.

7. The case structure of the power equipment unit according to claim 1, wherein

the power equipment includes a vehicle driving battery.

8. The case structure of the power equipment unit according to claim 1, wherein

the power equipment unit is arranged under a seat.

9. The case structure of the power equipment unit according to claim 8, wherein

the intake port is arranged to be positioned under the seat even in a state where the seat moves to a most front side or a most rear side of the vehicle.
