Description
[Technical Field]
[0001] The present disclosure relates to a housing and a vehicle charging device. [Background technology]
[0002] Patent Document 1 discloses a stationary power conversion device. This power conversion device has a circuit component housing space in which circuit components are housed. A waterproof box housing the circuit components is arranged in the circuit component housing space. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Publication No. 2020-36456 Summary of the Invention [Problem to be solved by the invention]
[0004] In the above-described conventional example, waterproofing of the circuit components is achieved by disposing a waterproof box inside the housing, but there may be cases where the housing itself needs to be waterproof, such as a configuration without a waterproof box. A housing typically has a housing body with an opening for accommodating circuit components and the like, and a lid that covers the opening. It is conceivable that moisture from outside the housing may enter through the gap between the lid and the housing body. Therefore, it is necessary to interpose a waterproof member made of an elastic material such as rubber between the periphery of the lid and the housing body.
[0005] Here, the waterproof member is sandwiched between the lid and the housing body, and is in close contact with the lid and the housing body, thereby achieving a waterproof effect. However, the housing of the power conversion device is relatively large, and the waterproofing member interposed between the periphery of the lid and the housing body is also relatively long. As a result, the clamping force of the waterproofing member can become uneven around the entire periphery of the lid. When the clamping force of the waterproofing member becomes uneven, the waterproofing effect also becomes uneven, and there is a risk that the required waterproofing effect cannot be achieved. Therefore, an object of the present disclosure is to provide a technique for making the clamping force for a waterproofing member as uniform as possible. [Means for solving the problem]
[0006] A housing according to an embodiment of the present disclosure includes a housing body having an opening and a flange portion along the periphery of the opening, a lid disposed opposite the opening and the flange portion, a waterproof member interposed between the flange portion and the lid, and a fixing member fixing the flange portion and the lid. The fixing member includes a spacer interposed between the flange portion and the lid. [Effects of the Invention]
[0007] According to the present disclosure, the force for clamping the waterproofing member can be made uniform. [Brief explanation of the drawings]
[0008] [Figure 1] FIG. 1 is a perspective view showing an example of a vehicle charging device according to an embodiment. [Figure 2] FIG. 2 is an exploded perspective view of the vehicle charging device. [Figure 3] FIG. 3 is an exploded perspective view of the housing. [Figure 4] FIG. 4 is an enlarged exploded perspective view of the main part of the housing. [Figure 5] FIG. 5 is an enlarged cross-sectional view of the periphery of the wide portion of the flange portion. [Figure 6] FIG. 6 is a view of the cutout portion in FIG. 4 as viewed along the X direction. DETAILED DESCRIPTION OF THE INVENTION
[0009] First, the contents of the embodiment will be listed and explained. [Outline of the embodiment]
[0010] (1) A housing according to an embodiment of the present disclosure includes a housing body having an opening and a flange portion along the periphery of the opening, a lid disposed opposite the opening and the flange portion, a waterproof member interposed between the flange portion and the lid, and a fixing member for fixing the flange portion and the lid. The fixing member includes a spacer interposed between the flange portion and the lid. According to the above configuration, the spacer allows the distance between the flange and the lid to be set to an appropriate value in advance over the entire periphery of the lid, thereby making it possible to make the clamping force for the waterproofing member as uniform as possible.
[0011] (2) In the housing of (1) above, the lid may have a lid body and a bent portion that extends from the periphery of the lid body toward the flange portion and covers the area between the lid body and the flange portion. In this case, the opening between the lid body and the flange portion is covered by the bent portion, so that the waterproof effect between the housing body and the lid can be further improved.
[0012] (3) In the housing of (1) or (2) above, when the spacer includes a plurality of pillar portions having fixing portions fixed to the flange portion, the fixing member may further include a plurality of screw members that are inserted into a plurality of through holes provided in the lid and screw-fastened to the plurality of pillar portions, thereby clamping the lid between the plurality of pillar portions. In this case, by arranging multiple pillars and multiple screw members at predetermined intervals around the circumferential direction of the flange portion, the lid can be fixed to the flange portion so that the waterproofing member is clamped with equal force around the entire periphery of the lid.
[0013] (4) In the housing of (3) above, when the flange portion has a plurality of narrow portions whose tips face the bending portion and a plurality of wide portions whose widths are wider than the narrow portions, and the wide portions have a plurality of fixing holes into which the fixing portions are press-fitted, the bending portion may have a plurality of notches recessed from the tip of the bending portion toward the lid body and into which the wide portions are inserted. In this case, the thickness in the surface direction of the flange portion required for press-fitting the column portion can be ensured by the wide portion. Furthermore, because the bent portion has a notch, it is possible to provide a wide portion that protrudes outward without increasing the overall size of the lid or widening the bent portion, which prevents the size of the housing from increasing and prevents the housing from becoming too large.
[0014] (5) In the housing of (4) above, the bending portion has a plate portion located between a pair of adjacent notches among the plurality of notches and having the tip portion, and the length of the tip edge of the plate portion is shorter than the distance between a pair of wide portions among the plurality of wide portions that are inserted into the pair of notches, and the pair of notches each have a bottom portion and a side portion connecting the end of the tip edge and the bottom portion, the side portion may be inclined so that the notch width of the pair of notches widens from the bottom portion toward the end portion. In this case, the width of the pair of cutout portions increases from the bottom to the end, making it easy to bring the lid and the housing body closer together and insert the pair of wide portions into the pair of cutout portions. Furthermore, when the pair of wide portions are inserted into the pair of cutouts, the pair of wide portions slide into contact with the side portions of the pair of cutouts and are guided by the pair of cutouts. At this time, the clearance between the pair of wide portions and the pair of side portions gradually decreases, and eventually, the relative movement between the pair of side portions and the pair of wide portions is restricted. If the position of the lid relative to the flange portion, determined by the positions of the pair of side portions and the pair of wide portions when this relative movement is restricted, is set to be an appropriate position for the lid, then when the pair of wide portions are inserted into the pair of cutouts, the lid will be guided to the appropriate position relative to the flange portion. Therefore, the pair of notches and the pair of wide portions can be used to position the lid.
[0015] (6) In the housing of (5) above, when the housing body and the lid have a rectangular shape, the bending portion includes a first bending portion along the long side of the lid and a second bending portion along the short side of the lid, and at least one pair of cutout portions is provided in each of the first bending portion and the second bending portion, at least one pair of wide portions may be provided on each of the long side and short side of the flange portion, corresponding to the pair of cutout portions. In this case, the lid can be positioned in both the long side direction and the short side direction.
[0016] (7) In the housing of (2) above, when the spacer includes a plurality of pillar portions having fixing portions fixed to the periphery of the lid body, the fixing member may further include a plurality of screw members that are inserted into a plurality of through holes provided in the flange portion and screw-fastened to the plurality of pillar portions, thereby clamping the flange portion between the plurality of pillar portions. In this case as well, the lid can be fixed to the flange portion by the plurality of posts and the plurality of screw members so that the waterproof member is clamped with uniform force over the entire peripheral edge of the lid.
[0017] (8) Another embodiment is a vehicle charging device. The vehicle charging device includes a power conversion device and a charging cable connected to a vehicle and configured to provide the vehicle with power output from the power conversion device. The power conversion device includes a cover and the housing described in (1) above that houses an electric circuit that outputs the power. According to the above configuration, the force for clamping the waterproofing member can be made as uniform as possible.

The rear side surface 6c is the surface of the outer surface of the housing 6 facing the Y2 direction. The output connector 2a is provided at the upper end of the first lateral side surface 6a.
[0025] The lid 12 is a rectangular plate-shaped member made of metal such as steel plate or aluminum alloy. The lid 12 is attached to the surface of the housing body 10 facing the Y1 direction. Therefore, the lid 12 has a front side surface 6e of the housing 6. The front side surface 6e is the surface of the outer surface of the housing 6 facing the Y1 direction. When attached to the housing body 10, the lid 12 closes the opening 10a. A waterproof member is interposed between the lid 12 and the housing body 10. The waterproof member will be described in detail later. Waterproof packing and sealing members are also provided in openings for bolt attachment provided in the lid 12 and the housing body 10. This allows the housing 6 to function as a waterproof case. An electric circuit group 14 required for power conversion and voltage boosting is housed inside the housing 6. By being housed inside the housing 6, the electric circuit group 14 is made waterproof.
[0026] The plurality of support members 30 are members that connect the decorative cover 8 and the housing 6 to each other. The decorative cover 8 is a box-shaped member made of metal such as steel plate or aluminum alloy. The decorative cover 8 is attached so as to cover the outside of the housing 6. The decorative cover 8 is attached to the housing 6 by a plurality of support members 30. The decorative cover 8 has a first side plate 8a, a second side plate 8b, a front plate 8c, and a top plate 8d. The first side plate 8a is disposed on the X2 side of the housing 6. The second side plate 8b is disposed on the X1 side of the housing 6. There is a slight gap between the inner surface of each plate of the decorative cover 8 and each surface of the housing 6.
[0027] A connector holder 16 and a cable holder 18 are provided on the first side plate 8a. The connector holder 16 has a function of holding the power supply connector 4b. When power is not being supplied to the electric vehicle, the power supply connector 4b is held by the connector holder 16. The cable holder 18 has a function of holding the cable main body 4a.

[0028] The power conversion device 2 further includes a heat sink 20, a heat sink cover 22, and a fan unit 24. The heat sink 20 is provided on the rear side surface 6c of the housing 6. The heat sink cover 22 is provided to cover the heat sink 20.
[0029] The fan unit 24 includes a pair of fans 24a and a fan cover 24b. The fan cover 24b holds the pair of fans 24a. The fan cover 24b is fixed to the heat sink cover 22 and the rear side surface 6c. The fan cover 24b is fixed above the heat sink 20. The heat sink cover 22 guides the airflow generated by the pair of fans 24a to the heat sink 20. This provides the heat sink 20 with the airflow generated by the pair of fans 24a.
[0030] The heat sink cover 22 is fixed to the heat sink 20 and a bracket 26. The bracket 26 is a member made of a metal such as a steel plate or an aluminum alloy, and is interposed between the heat sink cover 22 and the rear side surface 6c. The heat sink 20 is fixed to the rear side surface 6c by screws, an adhesive layer, or the like.
[0031] [About the case] Fig. 3 is an exploded perspective view of the housing 6. Note that unnecessary parts are omitted in Fig. 3. As described above, the housing 6 includes the housing body 10 and the lid 12. The housing main body 10 includes a box portion 34 and a flange portion 36. The box portion 34 is open in the Y1 direction and has an opening 10a. The flange portion 36 is provided along the periphery of the opening 10a. The flange portion 36 extends from the periphery of the opening 10a toward the outside of the box portion 34 along the XZ plane. The opening 10a is rectangular. Therefore, the flange portions 36 are provided in a rectangular shape along each side of the opening 10a. The flange portions 36 correspond to the peripheral edges of the lid 12. Therefore, when the lid 12 is attached to the housing body 10, the lid 12 is disposed opposite the opening 10a and the flange portions 36. In other words, the peripheral edges of the lid 12 and the flange portions 36 face each other.
[0032] As described above, the housing 6 also includes the waterproof member 38. The waterproof member 38 is interposed between the flange portion 36 and the lid 12. The waterproof member 38 is a long member made of an elastic material such as rubber. The waterproof member 38 is provided along the periphery of the flange portion 36 and the lid 12. Therefore, the waterproof member 38 is provided in a rectangular shape corresponding to the flange portion 36. The waterproof member 38 is sandwiched between the lid 12 and the flange portion 36.
[0033] The lid 12 is fixed to the housing body 10 by a plurality of screw members 40. Four screw members 40 are arranged on each edge of the long sides of the lid 12. Two screw members 40 are arranged on each edge of the short sides of the lid 12. The lid 12 of this embodiment is fixed to the housing body 10 by ten screw members 40.
[0034] FIG. 4 is an exploded perspective view showing an enlarged main part of the housing 6. As shown in FIG. As shown in FIGS. 4 and 3, the lid 12 has a lid main body 44 and a bent portion 46. The lid main body 44 is a rectangular plate-shaped member disposed opposite the opening 10a and the flange portion 36. The bent portion 46 is a portion extending from the periphery of the lid main body 44 toward the housing main body 10 (the Y2 direction side). The bent portion 46 is provided along the entire periphery of the lid main body 44. In other words, the bent portion 46 is provided on each of a pair of long sides and a pair of short sides of the lid main body 44. The bent portion 46 is formed by bending a metal plate that is the material for the lid 12.
[0035] The folded portion 46 includes a plurality of plate portions 48 and a plurality of notches 50. The plurality of plate portions 48 and the plurality of notches 50 are alternately arranged along the periphery of the lid body 44. As shown in FIG. 4, the plurality of notches 50 are recessed in a rectangular shape from the tip of the bent portion 46 (plate portion 48) toward the lid main body 44 (Y1 direction side).
[0036] The flange portion 36 has a plurality of narrow portions 52 and a plurality of wide portions 54. The wide portions 54 have a width greater than the narrow portions 52. The width of the flange portion 36 is the dimension from the edge of the opening 10a to the tip of the flange portion 36. The narrow portions 52 and the wide portions 54 are alternately provided along the periphery of the opening 10a (the circumferential direction of the flange portion 36).
[0037] The wide portions 54 are provided corresponding to the cutouts 50. Therefore, the wide portions 54 are inserted into the cutouts 50 when the lid 12 is attached to the housing body 10. Furthermore, a plurality of pillar portions 41 are provided on the plurality of wide portions 54. The plurality of pillar portions 41 are arranged at predetermined intervals along the circumferential direction of the flange portion 36. The plurality of pillar portions 41 can be fastened to a plurality of screw members 40 by screws. The plurality of screw members 40 are fastened to the plurality of pillar portions 41 to fix the lid 12 to the housing body 10 .
[0038] Fig. 5 is an enlarged cross-sectional view of the periphery of the wide portion 54 of the flange portion 36. Fig. 5 shows the pillar portion 41, screw member 40, etc. provided on the wide portion 54, but the pillar portions 41, screw members 40, etc. in the other wide portions 54 have the same configuration.
[0039] 5, the waterproof member 38 is sandwiched between the lid 12 and the flange portion 36, as described above. Therefore, the waterproof member 38 is in close contact with the lid 12 and the flange portion 36 while being elastically deformed to an appropriate degree. This allows the waterproof member 38 to prevent moisture from entering the inside of the housing 6 from between the lid 12 and the flange portion 36.
[0040] In FIG. 5, the pillar portion 41 is a cylindrical member made of a metal such as steel or an aluminum alloy. The wide portion 54 has a fixing hole 55 for fixing the column portion 41 . The pillar portion 41 has a fixing portion 41b on its outer circumferential surface. The fixing portion 41b is formed to have a larger diameter than the other portions of the pillar portion 41. The fixing portion 41b is press-fitted into the fixing hole 55 and fixed. The column portion 41 also has a female threaded hole 41a. The female threaded hole 41a passes through the center of the column portion 41. A female thread is provided on the inner peripheral surface of the female threaded hole 41a. A screw member 40 is screwed into the female threaded hole 41a.
[0041] A plurality of through holes 44a are provided in the lid main body 44. The screw members 40 are inserted into the plurality of through holes 44a. Therefore, the plurality of through holes 44a are provided corresponding to the plurality of column portions 41. The screw member 40 has a head 40a and an externally threaded portion 40b. The externally threaded portion 40b is inserted into the through-hole 44a and screwed into the internally threaded hole 41a of the column portion 41.
[0042] The outer diameter of the pillar portion 41 is larger than the inner diameter of the through-hole 44a. When the screw member 40 is screwed into the column portion 41, the lid main body 44 is clamped between the head portion 40a and the column portion 41. As a result, the lid 12 is fixed to the flange portion . In this way, the plurality of screw members 40 and the plurality of column portions 41 constitute a fixing member 42 that fixes the flange portion 36 and the lid 12 together.
[0043] Furthermore, the plurality of pillars 41 fixed to the flange 36 are interposed between the flange 36 and the lid main body 44. Therefore, the plurality of pillars 41 determine the distance between the flange 36 and the lid main body 44. Therefore, the plurality of pillars 41 form a spacer 43 interposed between the flange 36 and the lid main body 44. That is, the fixing member 42 includes a spacer 43 including a plurality of pillar portions 41 and a plurality of screw members 40 .
[0044] According to the above configuration, the spacer 43 allows the distance between the flange portion 36 and the lid body 44 to be set to an appropriate value in advance over the entire periphery of the lid body 44. Therefore, the force for clamping the waterproof member 38 can be made as uniform as possible over the entire periphery of the lid body 44. That is, the spacer 43 includes a plurality of pillar portions 41 arranged at predetermined intervals around the circumferential direction of the flange portion 36, and a plurality of screw members 40 that clamp the lid body 44 between the plurality of pillar portions 41 are screwed to the plurality of pillar portions 41, so that the force clamping the waterproof member 38 can be made as even as possible around the entire periphery of the lid body 44.
[0045] 5, the tip 48a of the plate portion 48, which is the tip of the bent portion 46, is located on the Y2 direction side of the flange portion 36. Therefore, the bent portion 46 covers the opening between the lid main body 44 and the flange portion 36. More specifically, the tip 52b of the narrow portion 52 of the flange portion 36 faces the plate portion 48 of the bent portion 46. As a result, the plate portion 48 covers the opening between the lid main body 44 and the narrow portion 52. This can further improve the waterproof effect between the housing body 10 and the lid 12.
[0046] Furthermore, a tip 54a of the wide portion 54 of the flange 36 protrudes beyond a tip 52b of the narrow portion 52. The part of the wide portion 54 that protrudes beyond the tip 52b of the narrow portion 52 is inserted into the cutout portion 50. Here, the fixing holes 55 into which the column portions 41 are press-fitted and fixed are provided in the wide portions 54. This allows the wide portions 54 to ensure the thickness in the planar direction of the flange portion 36 that is necessary for press-fitting the column portions 41. Furthermore, because the bent portion 46 has the notch 50, it is possible to provide the wide portion 54 that protrudes outward without increasing the overall size of the lid 12 or widening the bent portion 46. As a result, it is possible to suppress an increase in the size of the housing 6, and the housing is prevented from becoming too large.
[0047] FIG. 6 is a view of the cutout portion 50 in FIG. 4 as viewed along the X direction. 6, a pair of adjacent cutout portions 50 is also referred to as a pair of cutout portions 501. In addition, the plate portion 48 located between the pair of cutout portions 501 is also referred to as a plate portion 481. Furthermore, the pair of wide portions 54 inserted into the pair of cutout portions 501 is also referred to as a pair of wide portions 541.
[0048] Each of the pair of cutout portions 501 has a bottom portion 501a and a first side portion 501b. The bottom 501a is a bottom portion on the Y1 direction side of the cutout portion 501. The first side portion 501b is a portion connecting an end of the bottom 501a and the end portion 481a1. The end portion 481a1 is an end portion of the leading edge 481a of the plate portion 481. First side portion 501b is inclined so that the width of cutout portion 501 increases from bottom portion 501a toward end portion 481a1. Note that the cutout width is the width dimension of cutout portion 501 in the Z direction. As shown in FIG. 6, the length L of the leading edge 481a of the plate portion 481 is shorter than the distance W between the pair of wide portions 541. Furthermore, a relatively wide gap is provided between the pair of second side portions 501c and the pair of wide portions 541. The pair of second side portions 501c are sides of the pair of cutout portions 501 opposite to the first side portions 501b.
[0049] In this case, the cutout width of the pair of cutout portions 501 widens from the bottom 501a toward the end 481a1, making it easy to bring the lid 12 and the housing main body 10 closer together along the Y direction and insert the pair of wide portions 541 into the pair of cutout portions 501.
[0050] Furthermore, when the pair of wide portions 541 are inserted into the pair of cutout portions 501, the pair of wide portions 541 come into sliding contact with the first side portions 501b of the pair of cutout portions 501 and are guided by the pair of cutout portions 501. At this time, the clearance between the pair of wide portions 541 and the pair of first side portions 501b gradually decreases, and ultimately, the relative movement between the pair of first side portions 501b and the pair of wide portions 541 is restricted. In this embodiment, the position of the lid 12 relative to the flange portion 36, which is determined by the positions of the pair of first side portions 501b and the pair of wide portions 541 when the relative movement is restricted, is set to an appropriate position for the lid 12. Therefore, by inserting the pair of wide portions 541 into the pair of cutout portions 501, the lid 12 is guided to an appropriate position relative to the flange portion 36. In this way, the pair of notches 501 and the pair of wide portions 541 can be used to position the lid 12.
[0051] The positions of the multiple through holes 44a of the lid 12 that has been guided to the appropriate position approximately coincide with the positions of the multiple pillar portions 41. This makes it easy to screw the multiple screw members 40 into the multiple pillar portions 41.
[0052] In this embodiment, a pair of notches 501 having the first side portions 501b are provided in each of the bending portions 46, namely, the bending portion 46 (first bending portion) along the long side of the lid main body 44 and the bending portion 46 (second bending portion) along the short side of the lid main body 44. In this case, the lid 12 can be positioned in both the long side direction (Z direction) and the short side direction (X direction).
[0053] 〔others〕 It should be noted that the embodiments disclosed herein are to be considered as illustrative in all respects and not restrictive. In the above embodiment, the spacer 43 includes a plurality of pillar portions 41.
