Description

[Technical Field]

[0001] The present disclosure relates to a housing, a vehicle charging device, and a method for manufacturing the housing. [Background technology]

[0002] Patent Document 1 discloses a method for manufacturing an outer sill formed by combining an inner panel and an outer panel. This side sill is made by spot welding the inner panel and the outer panel together and then dip painting. A gap is provided between the joint of the inner panel and the joint of the outer panel in a portion other than the welded portion. During dip painting, paint penetrates into this gap and forms a coating on both joints, thereby enhancing the rust prevention effect. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 60-49875 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional example, dip coating is performed, so even if there is a relatively small gap between the parts, the paint will get into the gap, reducing the frequency of coating defects such as areas on the part surface where the paint film is not formed. However, with painting methods other than dip painting, such as spray painting, it is difficult to get paint into narrow gaps, increasing the frequency of painting defects.Furthermore, as in the above-mentioned conventional example, the inner and outer panels may cover each other's inner surfaces, preventing the paint from reaching them, increasing the frequency of painting defects. Therefore, an object of the present disclosure is to provide a technique that can reduce the frequency of occurrence of painting defects. [Means for solving the problem]

[0005] An embodiment of the present disclosure is a housing disposed inside a cover. The housing includes a housing main body and a support member interposed between the inner surface of the cover and the outer surface of the housing main body. The support member includes a first fixing portion having a first fixing surface that abuts and is fixed to the inner surface, a base portion that is fixed to the outer surface, and a single first support pillar that connects the base and the first fixing portion. The first fixing portion and the base are connected by only the single first support pillar. [Effects of the Invention]

[0006] According to the present disclosure, the frequency of occurrence of painting defects can be reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0008] First, the contents of the embodiment will be listed and explained. [Outline of the embodiment]

[0009] (1) An embodiment of the present disclosure is a housing disposed inside a cover. The housing includes a housing main body and a support member interposed between the inner surface of the cover and the outer surface of the housing main body. The support member includes a first fixing portion having a first fixing surface that abuts and is fixed to the inner surface, a base portion that is fixed to the outer surface, and a single first support pillar that connects the base and the first fixing portion. The first fixing portion and the base are connected only by the single first support pillar.

[0010] According to the above configuration, the first fixed portion and the base portion are connected by only one first support pillar, so the first support pillar does not face the outer surface of the housing body, thereby preventing the first support pillar from covering the outer surface of the housing body. As a result, when painting the housing using a painting method other than dip painting, such as spray painting, the paint can be applied appropriately to the outer surface of the support member and the outer surface of the housing body, reducing the frequency of poor painting.

[0011] (2) In the housing of (1) above, when the first fixed portion, the base, and the single first support pillar each have a flat plate shape, the support member may further include a first bent portion bent from the edge of the first fixed portion in the direction opposite to the direction in which the first fixed surface faces and connected to a first end of the first support pillar, and a second bent portion bent from the edge of the base and connected to a second end of the first support pillar. In this case, the first fixing portion, the base portion, and the first support column can be formed by bending a single strip-shaped flat plate.

[0012] (3) In the housing of (1) or (2) above, the one first support pillar may extend in a direction perpendicular to the outer surface. In this case, it is possible to reliably prevent the first support strut from covering the outer surface of the housing body.

[0013] (4) In any one of the housings (1) to (3) above, when the support member further includes a second fixing portion having a second fixing surface that abuts and is fixed to the inner surface, and a second support pillar that connects the base and the second fixing portion, the second fixing portion and the base may be connected only by the second support pillar. In this case, the first support column and the second support column can be protruded from one base portion.

[0014] (5) 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 supplying the power output from the power conversion device to the vehicle. The power conversion device includes a cover and the housing described in (1) above that houses an electric circuit that outputs the power and is disposed inside the cover.

[0015] (6) Another embodiment is a method for manufacturing a housing disposed inside a cover. The manufacturing method includes the steps of: providing a support member on a housing body of the housing, the support member being interposed between the inner surface of the cover and the outer surface of the housing body; and painting the outer surface of the housing body on which the support member is provided. The support member includes a first fixing portion having a first fixing surface that abuts and is fixed to the inner surface, a base that is fixed to the outer surface, and a single first support pillar that connects the base and the first fixing portion. The first fixing portion and the base are connected by only the single first support pillar. In this case as well, the paint can be applied appropriately to the outer surface of the support member and the outer surface of the housing body, reducing the frequency of poor painting.

[0034] Fig. 4 is an enlarged perspective view of the first holder support member 34 in Fig. 3. Fig. 5 is a cross-sectional view showing the first holder support member 34 in the power conversion device 2. Fig. 4 shows the appearance of the first holder support member 34 when fixed to the first lateral side surface 6a. Fig. 5 shows a cross-section of the first holder support member 34 when the housing 5 is placed inside the decorative cover 8.

[0035] 4 and 5, the first holder support member 34 includes a first fixing portion 40, a base portion 41, and a first support pillar 42. The first holder support member 34 is a member formed by bending a strip-shaped flat plate made of steel plate, aluminum alloy plate, or the like. Therefore, the first fixing portion 40, the base portion 41, and the first support pillar 42 are integral with each other. A second fixing portion 43 and a second support pillar 44, which will be described later, are also integral with these.

[0036] The first fixing portion 40 has a rectangular plate shape. The first fixing portion 40 has a first fixing surface 40a. The first fixing surface 40a faces in the X2 direction. The first fixing surface 40a is a surface that abuts and is fixed against the inner surface 8a1 of the first side plate 8a of the decorative cover 8. The first fixing portion 40 has a through hole 40b. The through hole 40b passes through the first fixing portion 40 along the X direction. A nut 45 is provided on the surface opposite the first fixing surface 40a. The center of the female thread portion 45a of the nut 45 coincides with the center of the through hole 40b. A bolt 46 is screwed into the nut 45.

[0037] The male thread portion 46a of the bolt 46 is inserted through the mounting hole 16a, the through hole 8a2, and the through hole 40b, and is screwed into the nut 45. The mounting hole 16a is a hole provided in the connector holder 16. The through hole 8a2 is a hole provided in the first side plate 8a of the decorative cover 8. When the bolt 46 is tightened, the first fixing portion 40, the first side plate 8a, and the connector holder 16 are sandwiched between the head 46b of the bolt 46 and the nut 45. As a result, the first fixing portion 40 is fixed in contact with the inner surface 8a1 of the first side plate 8a.

[0038] The base 41 has a rectangular plate shape. A surface 41a of the base 41 facing the X1 direction abuts against the first lateral side surface 6a. The base 41 has a pair of through holes 41b. The pair of through holes 41b are arranged side by side in the Z direction. The pair of through holes 41b penetrate the base 41 along the X direction.

The first bent part 48 is bent from the edge of the first fixed part 40 on the Y1 direction side in the X1 direction (the direction opposite to the direction in which the first fixed surface 40a faces) and is connected to the first end part 42a of the first support pillar 42. The first support pillar 42 and the base 41 are connected by a second bent portion 49. The second bent portion 49 is bent in the X2 direction from the edge of the base 41 on the Y2 side and connected to a second end portion 42b of the first support pillar 42. In this manner, the first fixed portion 40 and the base portion 41 are connected by only one first support pillar 42 . Furthermore, at least three sides of the space surrounded by the first lateral side surface 6a of the housing main body 6, the first support pillar 42, and the first fixing part 40 are open. That is, of the space surrounded by the first lateral side surface 6a of the housing main body 6, the first support pillar 42, and the first fixing part 40, the sides in the Z1 direction, the Z2 direction, and the Y2 direction are open.

[0040] In addition, the first holder support member 34 of this embodiment has a first bent portion 48 connecting the first fixed portion 40 and the first support pillar 42, and a second bent portion 49 connecting the base portion 41 and the first support pillar 42, so that the first fixed portion 40, the base portion 41, and the first support pillar 42 can be formed by bending a single strip-shaped flat plate.

[0041] Furthermore, the first holder support member 34 includes a second fixing portion 43 and a second support pillar 44.

[0043] In this way, the first holder support member 34 connects the first lateral surface 6a to the first side plate 8a of the design cover 8 and the connector holder 16, and supports the design cover 8 and the connector holder 16 relative to the housing body 6.

[0044] FIG. 6 is an enlarged perspective view of the second holder support member 35 in FIG. The second holder support member 35 includes a first fixing portion 60, a base 61, and a first support pillar 62. The first fixing portion 60, the base 61, and the first support pillar 62 have the same configuration as the first fixing portion 40, the base 41, and the first support pillar 42. Similar to the first holder support member 34, the second holder support member 35 is a member formed by bending a strip-shaped flat plate made of steel plate, aluminum alloy plate, etc. Therefore, the first fixing portion 60, the base portion 61, and the first support column 62 are integral with each other.

[0045] The first fixing portion 60 has a rectangular plate shape. The first fixing portion 60 has a first fixing surface 60a.

The pair of bolts 65 are inserted into through holes provided in the cable holder 18 , the first side plate 8 a and the first fixing portion 60 , and are screwed into the pair of nuts 64 . When the pair of bolts 65 are tightened, the first fixing portion 60, the first side plate 8a, and the cable holder 18 are sandwiched between the bolts 65 and the nuts 64. As a result, the first fixing portion 60 is fixed in contact with the inner surface 8a1 of the first side plate 8a. The base 61 has a rectangular plate shape and is fixed to the first lateral side surface 6a by a pair of rivets 66.

[0046] The first support pillar 62 has a rectangular plate shape. The first support pillar 62 is a member that connects the base 61 and the first fixed part 60. The first support pillar 62 extends in a direction (X direction) perpendicular to the first lateral side surface 6a. The first fixed portion 60 and the base portion 61 are connected by only one first support post 62 .

[0047] In this way, the second holder support member 35 connects the first lateral surface 6a to the first side plate 8a of the decorative cover 8 and the cable holder 18, and supports the decorative cover 8 and the cable holder 18 relative to the housing body 6.

[0048] FIG. 7 is an enlarged perspective view of the lateral support member 32 in FIG. The lateral support member 32 includes a first fixed portion 70, a base portion 71, and a first support column 72. The first fixed portion 70, the base portion 71, and the first support column 72 have the same configuration as the first fixed portion 40, the base portion 41, and the first support column 42. Similar to the first holder support member 34, the lateral support member 32 is a member formed by bending a strip-shaped flat plate made of steel plate, aluminum alloy plate, etc. Therefore, the first fixing portion 70, the base portion 71, and the first support column 72 are integral with each other.

[0049] The first fixing portion 70 has a shape that is elongated in the Y direction. The first fixing portion 70 has a first fixing surface 70a. The first fixing surface 70a is a surface that abuts against and is fixed to the inner surface 8a1 of the first side plate 8a of the decorative cover 8. The first fixing portion 70 has a pair of screw holes 70b formed therein. A pair of bolts 75 are threadedly engaged with the pair of screw holes 70b (FIG. 3). The pair of bolts 75 are inserted into a pair of through holes formed in the first side plate 8a and are threadedly engaged with the pair of screw holes 70b. When the pair of bolts 75 are tightened, the first side plate 8a is sandwiched between the bolts 75 and the first fixing portion 70. As a result, the first fixing portion 70 is fixed in contact with the inner surface 8a1 of the first side plate 8a. The base 71 has a rectangular plate shape and is fixed to the first lateral side surface 6a by a pair of rivets 76.

[0050] The first support pillar 72 has a rectangular plate shape and is a member that connects the base 71 and the first fixed part 70. The first support pillar 72 extends in a direction (X direction) perpendicular to the first lateral side surface 6a. The first fixed portion 70 and the base portion 71 are connected by only one first support post 72 .

[0051] Here, the housing 5 of the power converter 2 of this embodiment is obtained by providing a plurality of support members 30 on the housing main body 6, and then painting the outer surface of the housing main body 6 on which the plurality of support members 30 are provided. It is not necessary to paint the entire outer surface of the housing body 6, but it is sufficient to paint at least the surface of the outer surface of the housing body 6 on which the support members are provided. After the outer surface of the housing body 6 is painted, the decorative cover 8 is fixed to the multiple support members 30.

[0052] According to the above configuration, the first fixing portion 40 and the base portion 41 of the first holder support member 34 are connected by only the single first support pillar 42, and therefore the first support pillar 42 does not face the first lateral side surface 6a, which is the outer surface of the housing main body 6. This prevents the first support pillar 42 from covering the first lateral side surface 6a. In addition, the second support column 44 can be prevented from covering the first lateral side surface 6a. Furthermore, the second holder support member 35 and the lateral support member 32 are similar to the first holder support member 34. That is, the first support columns 62, 72 do not face the first lateral side surface 6a. This prevents the first support columns 62, 72 from covering the first lateral side surface 6a.

[0053] As a result, when painting the housing 5 using a painting method other than dip painting, such as spray painting, the paint can be applied appropriately to the outer surface of the support member 30 and the first lateral side surface 6a of the housing main body 6, reducing the frequency of poor painting.

[0054] In addition, the first holder support member 34 of this embodiment further includes a second fixing portion 43 and one second support pillar 44, and since the second fixing portion 43 and the base 41 are connected by only the one second support pillar 44, the first support pillar 42 and the second support pillar 44 can be protruded from the single base 41.

[0055] 〔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 embodiments, the first support pillar included in the support member 30 has a flat plate shape, but the first support pillar may be a rod-shaped member as long as it can connect the first fixed portion and the base. Similarly, the shapes of the first fixed portion and the base are not limited as long as they can be fixed to each other.

[0056] The scope of the present invention is defined by the claims, not by the meaning described above, and is intended to include meanings equivalent to the claims and all modifications within the scope thereof. [Explanation of symbols]
