SOLUTION: The battery case 11 is partitioned into a cell space 12 and a hanging hook space 13, the cell space 12 storing a plurality of cells 14 in order and the hanging hook space 13 containing a hanging hook storage 15 storing a hanging hook for hanging a battery when replaced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery case, and more particularly, to a battery case capable of storing a suspender for suspending a battery when the battery is replaced.

[0002]

2. Description of the Related Art As shown in FIG. 6, a battery type forklift has a battery 1 mounted on a machine base. The battery 1 has a structure in which a number of battery cells corresponding to the capacity are accommodated in a battery case, and adjacent battery cells are electrically connected to each other. For example, as shown in FIG. 7, a battery 1 having a capacity of 48 V is configured by accommodating a total of 24 2 V battery cells 3 in 4 rows and 6 columns in a battery case 2. When it is desired to configure the battery 1 having a capacity of 36 V using the same battery case 2, as shown in FIG. 8, by inserting spacers 4 for one row, the battery cells 3 each having 2 V are arranged in three rows and six columns. A total of 18 were accommodated.

In order to replace the battery 1, such as shown in FIG. 6, the seat stand 5 is first opened, the rear toe board 6 is removed, the side hood 7 is opened, and the battery plug 8 is removed. As shown in the drawing, after the battery 1 was hung by using the hanger 9 and removed from the machine base, a new battery 1 was similarly hung by the hanger 9 and mounted on the machine base.

[0004]

As described above, the hanger 9 is indispensable for the replacement of the battery 1, but conventionally, the hanger 9 has been stored in a predetermined place such as a factory where the battery 1 is replaced. . For this reason, there is a problem that the hanging tool 9 must be brought from the storage place every time the replacement work is performed. Further, after the work is completed, the hanging tool 9 must be stored again in a predetermined place, and there is a fear that the hanging tool 9 may be lost due to forgetting to store it. The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a battery case capable of storing a hanging tool.

[0005]

SUMMARY OF THE INVENTION A battery case according to the present invention has a cell space for accommodating a plurality of battery cells, a hanger space separated from the cell space, and a hanger space. And a suspender case for inserting a suspender for suspending the battery. A space for cells and a space for suspenders are defined in the battery case, and a suspender case is disposed in the space for suspenders.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a battery case according to the embodiment. A cell space 12 is defined in the battery case 11 and a hanging space 13 is defined separately from the cell space 12.
A plurality of battery cells 14 are arranged and stored in the cell space 12. On the other hand, a hanging tool case 15 is arranged in the hanging tool space 13. As shown in FIG. 2, the hanging device holder 15 has a box shape with an open top,
It has substantially the same size as one battery cell 14.

As shown in FIG. 3, the battery case 11 has a size to accommodate a total of 25 battery cells 14 in 5 rows and 5 columns, of which a space for one battery cell is suspended. The space for the remaining 24 battery cells is defined as the cell space 12. As a result, a battery having a capacity of 48 V is formed by accommodating 24 battery cells 14 each having 2 V.

[0008] A hanging device as shown in FIG. 9 is stored in a hanging device case 15 arranged in the hanging device space 13. Thus, the hanging device holder 1 in the battery case 11
Since the hanging device is stored in the storage unit 5, it is not necessary to go to the storage place when the battery is replaced, and the hanging device is less likely to be lost.

When a battery having a capacity of 36 V is constructed using the battery case 11 shown in FIG.
As shown in FIG. 2, a spacer 16 for one row is inserted, a space for one battery cell is used as a space 13 for a hanging tool, a space for another battery cell is used as a space 17 for a tool, and the remaining battery is used. The space for 18 cells may be used as the cell space 12.
In the tool space 17, for example, a tool case 19 raised to the bottom by a rib 18 is arranged as shown in FIG. 5, and tools such as a spanner and a driver can be stored.

[0010]

As described above, according to the present invention, the hanging case space is defined separately from the cell space in the battery case, and the hanging case compartment is arranged in the hanging space. A hanging tool can be provided for each case, which facilitates battery replacement work and prevents the hanging tool from being lost. Further, it is not necessary to set a storage location of the hanging tool in a factory or the like.
