ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a construction of a battery holding device which stores and holds a plurality of batteries.
BACKGROUND OF THE INVENTION
Generally, in order to ensure highly efficient charging and discharging cycles of batteries in a state of being loaded in apparatus, it is preferable to maintain the battery temperature within a specified range. This will assure the battery performance and life expectancy. To meet the purpose, the batteries held in a battery holding device are appropriately spaced apart. This arrangement improves the interior ventilation for the batteries. Accordingly, it becomes possible to control the battery temperature.
A conventional battery holding device of this type is mentioned in Japanese Open-Laid Patent No. 10-270006.
FIG. 7
is an exploded perspective diagram of a conventional battery holding device.
In
FIG. 7
, there is an arrangement of twenty one battery modules
88
each of which contains six series-connected batteries. A case body
81
is a rectangular box shaped with an open top and bottom. The case body
81
is molded in one-piece of plastic material. Right/left end wall
86
, partition wall
87
and cooling fin plate
84
of the case body
81
respectively have insertion holes
89
,
90
,
91
for the insertion of the battery module
88
. As for each group of these holes, there are 21 holes in total, 3 rows of the hole in a horizontal direction and 7 rows of the hole in a vertical direction, which are respectively made in the corresponding positions. The holes
89
,
90
,
91
are made at equal pitches horizontally and vertically, and are larger in diameter than the outer dimension of the battery module
88
. A rubber sheet
85
is secured to the partition wall
87
and serves to prevent vibration of the battery module
88
. To one end of case body
81
is secured a first end plate
82
. To the other end is secured a second end plate
83
. The end plates
82
and
83
are made up of plastic plate in which pass-bar
92
is insert-molded and secured. When bolt
93
is tightened, the pass bar
92
is electrically and mechanically connected to a square nut located at the positive electrode end or a hexagonal nut located at the negative electrode end of the battery module
88
. In this way, twenty one battery modules
88
arranged parallel with one another in a battery holding device are electrically series-connected by the pass-bar
92
of the first end plate
82
and a pass-bar (not shown) of the second end plate
83
.
In the case of such conventional construction, it is necessary to use many parts such as end plate
82
,
83
, cooling fin plate
84
, and rubber sheet
85
as well as case body
81
. In addition, the end plate
82
,
83
includes inserted pass bars, making the interior structurally complicated. Accordingly, a conventional battery holding device requires complicated procedures for assembling and finishing of parts. Also, it is very difficult to assemble the parts.
SUMMARY OF THE INVENTION
The present invention is to provide a low-cost, easy-to-assemble battery holding device which is simplified in structure and capable of maintaining the cooling and heating performance for batteries. A battery holding device embodying the present invention comprises a pair of plate type supports having a first plate type support and a second plate type support, and a projection disposed on at least one of the first and second plate type supports. The first support and the second support are opposed to each other. The projection extends toward the opposed support. The first support and the second support are connected to each other via the projection. A pair of the plate type supports and the projection form a casing.
Preferably, said space is formed by an inner surface of said casing, said casing has a space formed inside the casing, and said casing catches and holds a plurality of batteries arranged in rows in said space.
By this construction, the battery holding device is structurally simplified. It is not necessary to use many parts to form the casing, and the parts used have simple shapes. Accordingly, it is very easy to finish the parts. Also, the parts can be easily assembled. Further, the casing is able to provide ventilation for the batteries, and the battery holding device comprising this casing is able to ensure excellent cooling and heating performance.
