DESCRIPTION OF THE PREFERRED EMBODIMENTS An in-vehicle refrigerator according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the external appearance of an in-vehicle cool box, FIG. 2 is a partially cutaway side view of the in-vehicle cool box, FIG. 3 is a perspective view of a battery and a battery box, and FIG. FIG. 5 and FIG. 5 are diagrams for explaining the loading state of the in-vehicle cool box.

As shown in FIG. 5, the in-vehicle cool box 1 is loaded and delivered to a transport vehicle such as a truck T. As shown in FIG. 1, the insulated cold storage 1 for a vehicle has a substantially rectangular parallelepiped cold storage main body 2 formed by being surrounded by heat insulating walls and having an upper surface opened, and a heat insulating opening and closing upper opening of the cold storage main body 2. And a machine room 4 and a battery room 5 arranged vertically on the outer surface of the side wall of the cool box main body 2. The cool box main body 2 is for storing and keeping articles such as frozen and refrigerated goods, and a bi-on-sheet type evaporator (not shown) constituting a cooling device is arranged inside the heat insulating side wall. I have. In the machine room 4, as shown in FIG. 2, devices such as a compressor 6, a condenser fan 7, and a condenser 8 which are connected to the evaporator and constitute a cooling device are installed. The compressor 6 and the condenser fan 7 are connected to a battery B
The driving source circulates a refrigerant inside to form a refrigeration cycle, and keeps the cold storage main body 2 cooled to a low temperature.

On the side and the front of the battery chamber 5, a rectangular battery chamber side outlet 5a and a battery chamber front outlet 5b are formed, respectively. A battery chamber side door 9a and a battery chamber front door 9b are pivotally mounted on the lower edges of the battery chamber side outlet 5a and the battery chamber front outlet 5b, respectively. This allows the battery B to be taken in and out from either the side or the front of the battery chamber 5.

The battery B stored in the battery chamber 5 is
It has a substantially rectangular parallelepiped shape, and for example, a lead storage battery or the like is used. The battery B is stored and fixed in the battery chamber 5 in a state of being stored in the battery box 20 which is a box-shaped battery storage body having an open upper surface.

The battery B and the battery box 20
Is fixed to the floor surface 5c of the battery chamber 5 by the support frames 10 and 11, the battery fixing belt 12 and the belt fixing device 13. The support frames 10 and 11 are fixed to both sides of the battery B in the longitudinal direction, respectively.
1 so that the lower part is sandwiched between
Is arranged. The support frame 11 is provided with a hook 11a for hooking the hook 12a of the battery fixing belt 12. The battery fixing belt 12 has one end fixed to the floor surface 5c by a belt fixing device 13 and the other end connected to a hook 1.
2a is provided so that it can be hooked on the hook 11a of the support frame 11. Further, a fastener 12b is provided at an intermediate portion of the battery fixing belt 12, and by fastening the battery fixing belt 12 using the fastener 12b,
Battery B and battery box 20 are fixed to the floor of battery compartment 5. A caster hole 5d into which a caster 21 of a battery box 20, which will be described later, fits is formed in the floor 5c of the battery chamber 5. The caster hole 5d is formed slightly larger than the projecting portion of the caster 21 projecting from the bottom surface of the battery box 20. The caster holes 5d and the casters 21 are engaged with each other to further secure the battery box 20.

As shown in FIG. 3, the battery box 20 has a box shape with an upper surface opening, and is capable of accommodating a lower half of the battery B. This battery box 2
Handles 20a and 20b which protrude outward are formed at upper edges of both sides in the longitudinal direction of 0, respectively. At the four corners of the bottom surface of the battery box 20, casters 21 as sliding means for the battery box 20 are attached.
As the caster 21, for example, a ball caster having a free sliding direction is used. A plurality of spacers 22 are provided on the inner floor of the battery box 20 so that the stored battery B does not collide with the casters 21.

One handle 20a of the battery box 20
The towing arm 2 capable of towing the battery box 20
3 is attached. The towing arm 23 is formed by bending a bar-shaped member. Specifically, the bar-shaped member is bent in a substantially U-shape, and both ends are bent to about 90 ° C., as viewed from the side. It is formed so as to be substantially L-shaped. The end of the towing arm 23 is a handle 2
The pulling arm 23 is formed so as to be rotatable about 0a so that the L-shape extends along the peripheral surfaces of the battery box 20 and the battery B when rotated toward the battery B.

In such a battery box 20, the battery B can be stored by turning the traction arm 23 to open the upper surface of the battery box 20. After the battery B is stored, the traction arm 23 is rotated along the battery B, and then the battery B and the battery box 20 are integrated and stored in the battery compartment 5 of the in-vehicle cool box 1.

In the in-vehicle cool box 1, when the battery B is taken out of the battery compartment 5 for a charging operation or a replacement operation, it may be taken out together with the battery box 20. After being taken out of the battery chamber 5, the towing arm 23 can be rotated by holding the handle of the arm if the arm is rotated. Here, since the casters 21 are provided on the bottom surface of the battery box 20,
The towing movement can be performed very easily (see FIG. 4). Note that the battery box 20 can be pushed forward by using the towing arm 23. This facilitates movement of the battery B to the installation location of the charging device.

As described above, according to the in-vehicle cool box 1 according to the present embodiment, the battery B is connected to the battery box 2.
0 and can be taken in and out of the battery chamber 5. The caster 2 is provided on the bottom of the battery box 20.
Since the battery 1 is provided, the battery B can be easily moved and transported while being stored in the battery box 20. Thus, it is not necessary to lift and transport a heavy battery even when the battery B is charged or exchanged, so that the convenience is improved. Also, battery box 2
0 was stored in the battery chamber 5 together with the battery B,
There is no problem with the place where the battery box 20 is placed. Further, since the towing arm 23 is provided, the battery box 20 can be easily moved and transported, and the towing arm 23 can be stored along the battery B, so that the installation space is small. Further, since the casters 21 of the battery box 20 and the caster holes 5d of the battery chamber 5 are engaged with each other, the battery box 20 is securely fixed.

In the present embodiment, a ball caster having a free sliding direction is used as the sliding means of the battery box 20, but the present invention is not limited to this. For example, a caster that slides only in a predetermined direction may be used. You may. In addition, a structure having no rotating part such as a caster, for example, a projecting member may be attached to the bottom surface of the battery box 20, and the bottom surface of the projecting member may be formed so as to have a small coefficient of friction. .

Further, in this embodiment, one battery B is stored in the battery box 20. However, the present invention is not limited to this, and a plurality of batteries may be stored according to the capacity of the cooling device. You may.

[0020]

As described in detail above, according to the present invention,
The battery can be taken in and out of the battery chamber integrally with the battery housing. Further, since the sliding means is provided on the bottom surface of the battery housing, the battery can be easily moved and transported in a state of being housed in the battery housing. Therefore, it is not necessary to lift and transport a heavy battery even when the battery is charged or exchanged, which is highly convenient.
