That is, the locking portion 530 is installed in the casing 100 to be disposed above the tray 300, but may enter the front insertion hole 510 while the tray 300 is retracted. The tray 300 is provided to enter the rear insertion hole 520 in the drawn state.

On the other hand, the fixing means 500 may be provided such that the tray 300 is maintained in a raised state by a simple operation so that the tray 300 can be easily withdrawn and withdrawn without interference with the locking portion 530. To this end, the body 533a of the locking member 533 is rotatably inserted into the guide hole 532a of the guide member 532, and the locking groove 532b is recessed on the upper surface of the guide member 532. The head 533b of the locking member 533 is provided with a locking protrusion 533c protruding from the locking groove 532b. According to such a structure, the body 533a of the locking member 533 may enter the front insertion hole 510 or the rear insertion hole 520 while the locking protrusion 533c enters the locking groove 532b. When the locking projection 533c is separated from the locking groove 532b and placed on the upper surface of the guide member 532, the lowering is raised so as to be separated from the front insertion hole 510 or the rear insertion hole 520. Will be maintained.

In addition, as shown, a stopper 533d protruding along the outer circumferential surface of the body 533a is formed under the locking member 533, and the stopper 533d flows up and down inside the guide member 532. Lifting space portion 532c is inserted so that it can be formed. The stopper 533d and the lifting space portion 532c limit the range in which the locking member 533 can rise, thereby preventing the locking member 533 from being separated from the upper side of the guide member 532.

According to the integrated storage device for a battery pack of the present invention having the configuration as described above, the battery pack 10 used for electric vehicles, electric vehicles, energy storage systems (ESS), etc. are housed together with the control device 20 thereof. In addition, the battery pack 10 may be drawn out in the same manner as the drawer so that the battery pack 10 may be easily checked and maintained.

In addition, when the battery pack 10 generates heat or fires, the battery pack 10 may be quickly taken out and cooled, or the fire may be initially suppressed.

Hereinafter, an integrated accommodating device for a battery pack according to another exemplary embodiment of the present invention will be described with reference to FIGS. 6 to 8, but the same reference numerals will be given to the same components as those described above, and a repeated description thereof will be omitted. do.

As shown in FIG. 6, the integrated storage device for a battery pack according to another embodiment of the present invention further includes a gas spring 600 having one end connected to the tray 300 and the other end connected to the inside of the casing 100. Is done.

According to this, when the tray 300 is pulled out to some extent, the gas spring 600 pushes out the tray 300, so that the tray 300 can be easily taken out. In addition, when the tray 300 is retracted, the tray 300 may be rapidly moved to prevent an impact from occurring.

As shown in FIG. 7, an integrated accommodating device for a battery pack according to still another exemplary embodiment of the present invention includes a sensor 700 installed inside the casing 100 to detect an entry and an extraction of a tray 300; And an illumination lamp 800 installed in the casing 100 or the tray 300 to be connected to the sensor 700.

The sensor 700 is composed of a proximity sensor, a limit switch, and the like to detect the entry or withdrawal state of the tray 300.

The lighting lamp 800 is connected to the sensor 700, is turned on by the detection signal of the sensor 700 when the tray 300 is pulled out, and is detected by the detection signal of the sensor 700 when the tray 300 is pulled out. It goes out.

According to this, the lighting lamp 700 is turned on when the tray 300 is pulled out to illuminate the battery pack 10 and the accommodating space 110 so that the inspection and maintenance work can be easily performed.

As shown in FIG. 8, the integrated storage device for a battery pack according to another embodiment of the present invention is installed inside the casing 100, and is elastically deformed when the tray 300 is retracted to move the tray 300 forward. It further comprises a spring 900 to be pressed by.
