[0001]

[Industrial applications]

 The present invention relates to the structure of a frame of a housing that houses a power supply device and the like.

[0002]

[Prior Art]

 FIGS. 3A to 3C show a frame of a conventionally used case or a structure of the case. The casing frame 101 shown in FIG. 3 (A) is formed by three-dimensionally welding equilateral angle steel 102 having an L-shaped cross section. The welded portion is not shown in FIG. 3 (A). In the case 103 of FIG. 3B, the side wall 104 to which the door is attached is formed by processing a steel plate into a frame shape, and the other side walls 105 to 107, the top plate 108, and the bottom plate 109 are rectangular steel plates. It is formed by processing. In this case 103, the respective members are coupled to each other by welding, and equilateral angle steels 110 and 111 for reinforcement are fixed inside by welding. In the housing 112 of FIG. 3 (C), the side wall 113 to which the door is attached is made of a steel plate processed into a frame shape and the peripheral portion is bent to have a U-shaped cross section for reinforcement [see FIG. 3 (D)]. .. Further, the other side walls 114 to 116, the top plate 117, and the bottom plate 118 are formed by processing a steel plate into a rectangular shape and bending the peripheral portion into an L-shaped cross section for reinforcement [see FIG. 3 (D)]. Then, as shown in FIG. 3D, a casing 112 is configured by fixing each member using a bolt 121 and a nut 122. In this example as well, as in the case 103 of FIG. 3B, reinforcing equilateral angle steels 119 and 120 are fixed by welding.

[Problems to be solved by the device]

 When a frame for housing is manufactured by three-dimensionally welding equilateral angle steel 102 like the frame for housing shown in FIG. 3A, the strength is increased, but a skilled worker is required and a large amount is required. There is a problem that production is not possible. Further, since the frame for a casing as shown in FIG. 3 (A) is heavy, it has been a major obstacle to reducing the weight of the casing. Further, in the case structure (monocoque structure) shown in FIG. 3 (B), since the case frame is not used, sufficient mechanical strength cannot be necessarily obtained, and the case is painted after welding. There is a problem that the work is very troublesome. Moreover, the housing must be manufactured in advance before the power supply device is incorporated, which requires a storage space and is poor in portability. In addition, the case structure in which steel plates reinforced by bolts and nuts are combined as in the case of FIG. 3C basically does not use a frame for the case, and therefore, the equilateral angle steel for reinforcement is used. It is necessary to weld 119 and 120, which requires welding work, and there is a problem that sufficient strength cannot always be obtained only with the reinforcing equilateral angle steels 119 and 120.

An object of the present invention is to provide a frame for a housing which is easy to assemble and which can increase the strength of the housing without making the weight of the housing too heavy.

[0005]

[Means for Solving the Problems]

 The housing frame of the present invention comprises a pair of first and second frames, a top plate side frame fixing member and a bottom plate side frame fixing member. The first pair of frame bodies are integrally formed by processing a steel plate, and are arranged to face each other with a predetermined gap in the first direction. The second pair of frame bodies are integrally formed by processing a steel plate and are arranged to face each other with a predetermined gap in a second direction substantially orthogonal to the first direction. The upper ends of the first and second pair of frame members are bolted or riveted to the top plate side frame member fixing member, and the lower end portions of the first and second pair of frame members are the bottom plate side frame member fixing member. It is bolted or riveted to. The pair of opposing sides of the first pair of frame bodies, which are arranged to face each other with a predetermined space in the second direction, are fitted into the openings of the second pair of frame bodies, respectively. Associated with a second pair of frames. Further, at least a pair of opposing sides of each of the first and second pair of frame bodies is provided with a reinforcing portion having a L-shaped or U-shaped cross section formed by bending.

[0006]

[Action]

 In the present invention, since the first and second pair of frame bodies are integrally formed by processing steel plates, the frame bodies can be produced without the need for welding. In particular, when an automatic machine tool such as a numerically controlled machine tool is used to process steel sheets, it is possible to produce a large number of frames with high accuracy. In addition, since the reinforcing member having a L-shaped or U-shaped cross section is provided on at least a pair of opposing sides of the first and second pair of frame bodies by bending, the frame body is reinforced. The squareness of the corners of the frame can be maintained with the strength of the frame. The frame is configured such that the pair of opposite sides of the first pair of frame bodies are fitted into the openings of the second pair of frame bodies, respectively, and the upper and lower end portions of the first and second pair of frame bodies are respectively fitted. Since it can be assembled simply by bolting or riveting to the top plate side frame fixing member and the bottom plate side frame fixing member, the frame can be easily assembled. Further, since the housing frame of the present invention is composed of four frame bodies made by processing a steel plate and two frame body fixing members, it is relatively light in weight and can contribute to the reduction of the weight of the housing. .. Furthermore, when manufacturing a case having a device such as a power supply device inside by using the case frame of the present invention, the device is mounted on the case frame before the side wall is attached to the case frame. The advantage is that the device can be implemented easily. In addition, surface treatment such as painting can be performed before assembling the casing frame, which has the advantage of high work efficiency. Furthermore, since they can be assembled by bolting or riveting, they can be assembled at the installation location of the housing, and have the advantage of easy transportation.
