Abstract

(57) [Summary] [Purpose] To balance the strength of the upper and lower sides of frames that are stacked one above the other, and to make the maintenance side the front. [Structure] One bottom plate 3 (5) and two parallel side plates 4,
4 (6, 6) are vertically stacked, and the side plates 4, 4 (6, 6) are connected to the bottom plate 3.
(5) rises from either end or near both ends,
In the upper and lower frames 1 (2), the side plates are arranged at positions perpendicular to each other. Also, the direction of the frame without side plates is the front side 8, so 1). If the strength is the same as that of the conventional technology, the weight can be reduced by about 10%. 2). The maintenance side can be placed directly in front of you, making it easier to work.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a housing for a power supply device.

0002

[Conventional technology]

Conventionally, it has one bottom plate 19 and two parallel side plates 20, 20. 0 has shelf board supports 21, 21, and a shelf board 22 is attached on top of the shelf board supports 21, 21. There was a girder housing (Figure 6).

0003

[Problem that the idea aims to solve]

However, in the conventional case mentioned above, 1. The strength of the frame is unbalanced in the front-back and left-right directions, and the strength in one direction is weak. 2. There was a problem in that the main maintenance surface could not be brought to the front side 8.

0004 The purpose of the invention is to solve the above problems.

[0005]

[Means to solve the problem]

This invention consists of multiple frames that have one bottom plate and two parallel side plates stacked one on top of the other. It is a flat casing, and the side plates rise from both ends of the bottom plate or near both ends. , and in the upper and lower frames, the side plates are arranged at positions perpendicular to each other. is the body, In addition, it is a case in which the direction of the frame without side plates is the maintenance side for the mounted components.

[0006]

[Effect]

With the above configuration, the casing of the present invention: 1. The strength in the front-back and left-right directions was balanced. 2. The main maintenance area is now the front side.

[0007]

【Example】

An embodiment of the present invention will be described. FIG. 1 is an explanatory diagram of a casing showing a first example of the present invention. Frame 1 and bottom plate 3 The frame 2 has parallel side plates 4, 4, while the frame 2 also has a bottom plate 5 and a parallel side plate 6. , 6, and the side plates are stacked on the frame 2 so as to be perpendicular to each other, and screws or Fixed at rebate 7. Also, the left and right sides of the frame 2 serve as side plates 6, 6, and the frame 2 has side plates 6, 6. The open surface of the frame 2 is the front side 8.

[0008] Frame 2 Since frame 1 is stacked on top of the If you try to bend the entire frame in the front-back direction, the side plate 6 will be difficult to bend. If you try to bend the entire frame in the left and right direction, the side plate 4 will be difficult to bend. It works in a balanced manner. In addition, since the open side of the frame 2 is on the front side 8, the frame in Figure 1 of the present invention Although it is not shown in Figure 2, a storage battery is housed in it, and when replacing the storage battery, the front Replacement and maintenance can be done from side 8, making the work extremely easy.

[0009] FIG. 2 is an explanatory diagram of a casing showing a second example of the present invention. The difference from Figure 1 is the frame. The side plate 10 of the frame 9 is lower in height than the side plate 4, and the side plate 11 has punched holes 23. There is. The side plate 10 utilizes the level of the ceiling, and the plate 2 is convenient for placing equipment. The punched hole 23 can be used to install equipment or perform wiring work. It's convenient.

0010 FIG. 3 is an explanatory diagram of a casing showing a third example of the present invention. The difference from FIG. 1 is that the bottom plate 13 of the frame 12 is shorter than the bottom plate 5 of the frame 2. , the side plate 14 has a notch 24. If the bottom plate 13 is shortened, it will be convenient to attach equipment to the back side of the side panel 4. , Notch 24 is convenient for installing equipment or wiring work using this notch. be.

[0011] FIG. 4 is an explanatory diagram of a casing showing a fourth example of the present invention. The difference from Figure 1 is the frame. The side plate 4 of the frame 15 is not at the edge of the bottom plate 3 of the frame 15, but rises from near the edge. This is the point. FIG. 5 is an explanatory diagram of a casing showing a fifth example of the present invention. The difference from FIG. 1 is that both the side plate 4 of the frame 16 and the side plate 18 of the frame 17 are This is a point that rises not from both ends of the bottom plates 3 and 5, but from near both ends. FIG. 6 is an explanatory diagram of a casing showing the prior art. It has a bottom plate 19 and two parallel side plates 20, 20, and the two side plates 20, 20 are Each has a shelf support 21, 21, and a shelf 22 is placed on top of the shelf support 21, 21. , are fixed with screws or rivets 7.

0012 Therefore, when trying to bend the entire frame in the left and right direction, the side plates 20 and 20 are bent. Although it has sufficient strength, it is difficult to bend the entire frame in the front-back direction. When you try to bend it, the only things that work to make it difficult to bend are the bottom plate 19 and the shelf plate 22. Their longitudinal section modulus is very small, and their bending strength is weak.

[0013] Also, since the front side 8 is the side plate side, the structure is difficult to maintain. .

[0014]

[Effect of the idea]

As mentioned above, according to the present invention, 1. If the strength is the same as that of the conventional technology, the weight can be reduced by approximately 10%. Ta. 2. This has the effect of allowing the main maintenance surface to face the front, making maintenance work easier.
