Description

Technical Field

[0001] The present disclosure relates to an installation structure of a housing in a power supply device. Background Art

[0002] An example of a conventional power supply device is disclosed in Patent Document 1. The power supply device disclosed in the document includes components housed in the device, a fan, a radiator, and an outer shell. The outer shell is used to protect the components in the device, and includes a front panel, a rear panel, left and right side panels, a top panel, and the like. The above-mentioned parts of the outer shell are, for example, flat plate-shaped members formed using metal plates. The above-mentioned flat plate-shaped members of the outer shell are, for example, fixed using a plurality of bolts. In addition, the left and right side panels, in particular, need to be disassembled during maintenance such as replacement of components in the device, and it is desired that the assembly and disassembly is easy.

[0003] For example, in a power supply device for welding, since high voltage and high current power are supplied, the device size is sometimes enlarged. As the power supply device is enlarged, the size of each flat plate-shaped member constituting the outer cover is also enlarged. As a result, the weight of the flat plate-shaped member increases, and the number of bolts for fixing the flat plate-shaped member also increases, so the workability of the left and right side plate parts during assembly and maintenance is deteriorated.

The partition plate 19 is fixed to the two pillars 16 located on the y1 side of the y-direction by an appropriate method such as bolt fastening.

[0042] The housing 2 protects power supply components, fans, radiators, etc. in the power supply device A1. In this embodiment, the housing 2 includes side panels 21 and 22, a front panel 23, a rear panel 24, and a top panel 25. The housing 2 is formed of, for example, a metal plate.

[0043] The side panel 21 is shaped along the y direction and the z direction as a whole, and is located on the x1 side of the x direction. The side panel 22 is shaped along the y direction and the z direction as a whole, and is located on the x2 side of the x direction. The front panel 23 is shaped along the x direction and the z direction as a whole, and is located on the y1 side of the y direction. The rear panel 24 is shaped along the x direction and the z direction as a whole, and is located on the y2 side of the y direction. The top panel 25 is shaped along the x direction and the y direction as a whole, and is located on the z1 side of the z direction.

[0044] The side plate 21 and the side plate 22 correspond to an example of the "housing" of the present disclosure. The side plate 21 and the side plate 22 have substantially the same structure. Hereinafter, the structure of the side plate 21 will be described, and the description of the side plate 22 will be appropriately omitted.

[0045] like Figure 3 to Figure 6 As shown, the side plate 21 includes a main plate portion 211 , a grip portion 212 and a mounting portion 213 .

[0046] The main plate portion 211 is a flat plate along the y direction and the z direction, and is a main part of the side plate 21. The gripping portion 212 is a portion for the operator to grip when attaching and detaching the side plate 21, and is provided at two locations separated along the y direction in the main plate portion 211. The mounting portion 213 is a portion for mounting the side plate 21 to the support body 1. The mounting portion 213 is fixed to the x2 side in the x direction (the inner side in the first direction) relative to the main plate portion 211. In the example shown in the figure, the mounting portion 213 is provided on the z1 side in the z direction and the z2 side in the z direction in the main plate portion 211.

[0047] The mounting portion 213 includes a fixing portion 214, a connecting portion 215, and an embedded plate portion 216. The fixing portion 214 is a portion fixed to the main board portion 211, and is fixed to the main board portion 211 by a suitable method such as bolt fastening. In the example shown in the figure, the fixing portion 214 is a long rectangular shape with the y direction as the long side direction. The connecting portion 215 is a portion extending from the lower end of the fixing portion 214 to the x2 side (the inner side of the first direction) in the x direction. The connecting portion 215 is a long rectangular shape with the y direction as the long side direction.

[0048] like Figure 5 as well as Figure 6 As shown, the embedded plate portion 216 extends downward from the end of the x2 side of the connecting portion 215 in the x direction and is embedded in the opening portion 122 formed in the upper plate portion 12. In this embodiment, the embedded plate portion 216 extends to the z2 side in the z direction. Figure 6 As shown, the insertion plate portion 216 has a tapered portion 2161. The tapered portion 2161 is a portion whose length in the y direction decreases as it goes downward.

[0049] Figure 7 to Figure 9 21 is a diagram illustrating the steps of installing the side panel 21. Figure 5 When the side plate 21 is installed, the insertion plate portion 216 is inserted into the opening portion 122 from a state where the insertion plate portion 216 is not inserted into the opening portion 122 . Figure 7 The insertion plate portion 216 is shown in a state where it is not inserted into the opening portion 122 . Figure 8 as well as Fig. 9 The process of fitting the fitting plate portion 216 into the opening portion 122 is shown.

[0050] like Figure 7 As shown, when the embedded plate portion 216 is not embedded in the opening portion 122, the length in the x direction from the lower end 1231 of the extension portion 123 to the frame plate portion 121, i.e., the first dimension L1, is greater than the length in the x direction from the first surface 216a of the embedded plate portion 216 facing the x1 side of the x direction (the outer side of the first direction) to the second surface 211a of the main board portion 211 facing the x2 side of the x direction (the inner side of the first direction), i.e., the second dimension L2.

[0051] like Figure 7 As shown, when the lower end of the embedded plate portion 216 enters the opening portion 122, the lower end of the embedded plate portion 216 abuts against the extension portion 123, and the embedded plate portion 216 is embedded in the opening portion 122 by virtue of the deadweight of the side plate 21. The extension portion 123 is inclined so as to be located on the x2 side of the x-direction (the inner side of the first direction) as it moves downward. Thus, when the embedded plate portion 216 is embedded in the opening portion 122, the embedded plate portion 216 (installation portion 213) and the main board portion 211 are guided by the extension portion 123 and move to the x2 side of the x-direction. And, as shown in FIG. Figure 8As shown, the second surface 211a of the main plate portion 211 is in close contact with the frame plate portion 121. As described above, the first dimension L1 from the lower end 1231 of the extension portion 123 to the frame plate portion 121 is greater than the second dimension L2 from the first surface 216a of the embedded plate portion 216 to the second surface 211a of the main plate portion 211. Therefore, if the embedded plate portion 216 is further embedded in the opening portion 122, as shown in FIG. Fig. 9 As shown, at least one of the extension portion 123 and the embedded plate portion 216 is elastically deformed, and the main plate portion 211 moves toward the z2 side in the z direction while being in close contact with the frame plate portion 121. Furthermore, the side plate 21 is attached to the support body 1 by contacting the upper plate portion 12 through the contact portion 215 (see Figure 5 ).exist Figure 5 In the illustrated state, the main plate portion 211 is in close contact with the frame plate portion 121 and is pressed toward the frame plate portion 121 (the x2 side in the x direction) by the elastic restoring force of the extension portion 123 and the embedded plate portion 216 .

[0052] In the example shown in the figure, Figure 3 as well as Figure 4 As shown, the mounting portion 213 provided on the z1 side in the z direction has a plurality of (three) embedded plate portions 216. A plurality of (three) opening portions 122 corresponding to the three embedded plate portions 216 are formed in the upper plate portion 12. The three embedded plate portions 216 are respectively embedded in any one of the plurality of opening portions 122. In addition, the mounting portion 213 provided on the z2 side in the z direction has a plurality of (three) embedded plate portions 216. Two mounting portions 213 are provided on the z2 side in the z direction, the mounting portion 213 located on the y1 side in the y direction has two embedded plate portions 216, and the mounting portion 213 located on the y2 side in the y direction has one embedded plate portion 216. Although detailed illustration is omitted, in the bottom plate portion 11, similarly to the opening portions 122 and the extension portion 123 formed in the upper plate portion 12, a plurality of (three) opening portions and an extension portion are provided corresponding to the three embedded plate portions 216 located on the z2 side in the z direction. The three fitting plate portions 216 located on the z2 side in the z direction are respectively fitted into any one of the plurality of openings formed in the bottom plate portion 11 .

[0053] In addition, the mounting position and number of the mounting portion 213 relative to the main board portion 211 are not limited to the example shown in the figure. In addition, the number of the embedded plate portions 216 provided on the side plate 21 is also not limited to the example shown in the figure. In addition, in order to reliably fix the side plate 21 to the support body 1, for example, the peripheral edge of the side plate 21 (main board portion 211) can also be fixed to the support body 1 (frame plate portion 121) by bolts.

[0054] Next, the operation of this embodiment will be described.

[0055] According to the present embodiment, when the side plate 21 is mounted on the support body 1, the embedded plate portion 216 provided on the side plate 21 is embedded in the opening portion 122 formed in the upper plate portion 12. The embedded plate portion 216 extends downward at the mounting portion 213, and by embedding the embedded plate portion 216 into the opening portion 122 from the z1 side in the z direction to the z2 side in the z direction, the side plate 21 can be easily mounted on the support body 1. Thus, the side plate 21 can be easily loaded and unloaded. In addition, the support body 1 has an extension portion 123. The extension portion 123 is connected to the upper plate portion 12, and is bent at the end on the x1 side in the x direction (outer side of the first direction) relative to the opening portion 122 and extends downward. According to such a structure, when the embedded plate portion 216 is embedded in the opening portion 122, the embedded plate portion 216 abuts against the extension portion 123. Through the cooperation of these embedded plate portions 216 and the extension portion 123, the side plate 21 (main plate portion 211) and the support body 1 (frame plate portion 121) can be in close contact.

[0056] The extension portion 123 is inclined to be located on the x2 side of the x direction (the inner side of the first direction) as it goes downward. According to such a structure, when the embedded plate portion 216 is embedded in the opening portion 122, the embedded plate portion 216 (mounting portion 213) and the main plate portion 211 are guided by the extension portion 123 and move to the x2 side of the x direction, so that the main plate portion 211 can be in close contact with the frame plate portion 121.

[0057] In the present embodiment, the embedded plate portion 216 extends toward the z2 side of the z direction. When the embedded plate portion 216 is not embedded in the opening portion 122, the length in the x direction from the lower end 1231 of the extension portion 123 to the frame plate portion 121, i.e., the first dimension L1, is greater than the length in the x direction from the first surface 216a of the embedded plate portion 216 facing the x1 side of the x direction (the outer side of the first direction) to the second surface 211a of the main plate portion 211 facing the x2 side of the x direction (the inner side of the first direction), i.e., the second dimension L2. According to such a structure, as shown in reference to Figure 5 , Figure 8 as well as Fig. 9 As described above, when the embedded plate portion 216 is embedded in the opening portion 122, at least one of the extension portion 123 and the embedded plate portion 216 is elastically deformed, and the main plate portion 211 moves toward the z2 side in the z direction while being in close contact with the frame plate portion 121. Figure 5 ), the main board portion 211 is in close contact with the frame plate portion 121, and is pressed toward the frame plate portion 121 side (x2 side in the x direction) by the elastic restoring force of the extension portion 123 and the embedded plate portion 216. Therefore, the main board portion 211 can be more firmly and closely contacted with the frame plate portion 121.

[0058] In the present embodiment, the embedded plate portion 216 has a tapered portion 2161. The length of the tapered portion 2161 in the y direction decreases as it goes downward. According to such a structure, as the embedded plate portion 216 is embedded into the opening portion 122, the contact area of ​​the embedded plate portion 216 relative to the extension portion 123 increases. As a result, the elastic restoring force of the embedded plate portion 216 increases, and the pressing force of the main board portion 211 toward the frame plate portion 121 side (the x2 side in the x direction) increases. Therefore, the embedded plate portion 216 can be smoothly embedded in the opening portion 122, and when the side plate 21 is installed on the support body 1, the side plate 21 (main board portion 211) can be firmly and closely contacted with the support body 1 (frame plate portion 121).

[0059] In this embodiment, the side plate 21 has a plurality of mutually separated insertion plate portions 216. The support body 1 has a plurality of openings 122 (including openings not shown) corresponding to the plurality of insertion plate portions 216. With such a structure, the side plate 21 can be more stably attached to the support body 1.

[0060] The side plate mounting structure in the power supply device according to the present disclosure is not limited to the above-mentioned embodiment, etc. The specific structure of each part of the side plate mounting structure in the power supply device according to the present disclosure can be freely designed and changed in various ways.

[0061] In the above embodiment, the side panels 21 and 22 are equivalent to an example of the "housing" of the mounting structure of the housing in the power supply device involved in the present disclosure. The present disclosure is not limited to the structure of the above embodiment, and for example, the housing mounting structure of the present disclosure may be applied to the parts equivalent to the front panel 23 and the rear panel 24 in the above embodiment. In this case, the front panel 23 and the rear panel 24 are equivalent to an example of the housing of the present disclosure.
