Abstract

An auxiliary power storage device for an electric device installed in a vehicle, is connectable to a battery for the electric device in parallel to supply power to a vehicle load installed in the vehicle, and the auxiliary power storage device comprises a power storage portion and a housing case storing the power storage portion, and further the hosing case comprises a hole portion fitted to a terminal portion of the power storage portion, a mountain-shaped projecting portion integrally formed on a wall surface standing from a peripheral portion of the hole portion for preventing a liquid drop flowing down along the wall surface from intruding into the hole portion, and a projecting portion integrally formed along the peripheral portion of the hole portion for preventing a liquid drop from intruding into the hole portion from the peripheral portion of the hole portion.

First claim

1 . An auxiliary power storage device for an electric device installed in a vehicle, connectable in parallel to a battery for the electric device to supply power to a vehicle load installed in the vehicle, comprising:
a power storage portion having a terminal portion including an output terminal; and a housing case storing the power storage portion,
wherein the hosing case comprises:
a hole portion fitted to the terminal portion of the power storage portion;
a first guide portion provided on a wall surface standing from a peripheral portion of the hole portion for preventing a liquid drop flowing down along the wall surface from intruding into the hole portion; and
a second guide portion provided at the peripheral portion of the hole portion for preventing a liquid drop from intruding into the hole portion from the peripheral portion of the hole portion.

2 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
wherein the first guide portion is a projecting portion which is mountain-shaped and integrally formed with the wall surface.

3 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
wherein the second guide portion is a projecting portion which is integrally formed along the peripheral portion of the hole portion.

4 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
wherein the second guide portion is a groove portion which is integrally formed along the peripheral portion of the hole portion.

5 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
further comprising
a third guide portion provided under the hole portion for guiding a liquid drop intruded inside the power storage device from the hole portion to a discharging hole formed at a low portion of the housing case.

6 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 5 ,
wherein the third guide portion has a groove portion of downward inclination at the hole portion.

7 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 5 ,
wherein an inflow side open portion of the discharge hole is not flush in itself.

8 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
wherein the housing case comprises an upper case and a lower case, and the upper case is connected to the lower case such that the upper case covers a periphery of the lower case.

9 . The auxiliary power storage device for the electric device installed in the vehicle according to claim 1 ,
wherein the power storage portion is a lithium ion secondary battery or a nickel hydride battery.

10 . A vehicle incorporating an auxiliary power storage device for an electric device installed in the vehicle, connectable in parallel to a battery for the electric device to supply power to a vehicle load installed in the vehicle,
the auxiliary power storage device comprising a power storage portion and a housing case storing the power storage portion,
wherein the hosing case comprises:
a hole portion fitted to a terminal portion of the power storage portion;
a first guide portion provided on a wall surface standing from a peripheral portion of the hole portion for preventing a liquid drop flowing down along the wall surface from intruding into the hole portion; and
a second guide portion provided at the peripheral portion of the hole portion for preventing a liquid drop from intruding into the hole portion from the peripheral portion of the hole portion.
