[0044] As shown in FIG. 1 , the seal member 40 includes a connecting portion 45 that connects the first seal portion 41 and the second seal portion 42. The connecting portion 45 connects the first extension portion 41 a and the first extension portion 43 a. The connecting portion 45 connects the second extension portion 41 b and the second extension portion 43 b. The connecting portion 45 connects the third extension portion 41 c and the third extension portion 43 c. The connecting portion 45 connects the fourth extension portion 41 d and the fourth extension portion 43 d.

[0045] The housing 3 includes a guard portion 130 that guards the connector seal portion 44. As shown in Figures 12 and 15, the guard portion 130 includes a first guard 131 and a second guard 132. The first guard 131 is located around the connector mounting portion 18. The first guard 131 bends the tip of the saliva portion 7b toward the connector mounting portion 18 so that the tip side overlaps the lid 7 side of the first connector seal portion 44. The second guard 132 overlaps the edge portion 24 of the outward protrusion 22 and the tip side (first guard 131) of the saliva portion 7b.

[0046] As shown in FIGS. 1 and 12 , the lid 7 is formed in a plate shape. The vertical and horizontal lengths of the lid 7 are greater than the vertical and horizontal lengths of the electronic board 2. The lid 7 includes a plate portion 7a shaped in a plan view and a salient portion 7b provided on the edge of the plate portion 7a. The plate portion 7a is formed with a first protrusion 7a1 that protrudes inwardly into the case and a second protrusion 7a2 that protrudes inwardly into the case at a position spaced apart from the first protrusion 7a1. The first protrusion 7a1 has a flat surface 7a11 on the inside of the case that is flat. The salient portion 7b has a plurality of holes 9. The edge of the salient portion 7b is positioned in the fitting portion 19 when the lid 7 is fitted to the case body 6.

[0047] 1, 4, 5, 7, 14, and 15, the case body 6 includes a rod 55. The rod 55 extends from the case body 6 toward the lid 7 and supports the electronic board 2 separately from the vertical support portion 23. The lid 7 is a cylinder extending from the inner surface of the flat portion 13 of the lateral wall 10 toward the first protrusion 7a1. The tip of the cylinder is flat.

[0048] 1 and 5 to 7, when fitting the electronic board 2 into the case body 6, the mounting portion 5a1 of the first connector 5a is inserted into the insertion portion 46 of the first connector seal portion 44a, and the mounting portion 5b1 of the second connector 5b is inserted into the insertion portion 47 of the second connector seal portion 44b. The first seal portion 41 of the seal member 40 is brought into contact with the other surface 2U of the electronic board 2 (the second surface facing the lid 7).

[0049] Then, with the first connector seal 44a and the second connector seal 44b attached around the first connector 5a and the second connector 5b, the first connector seal 44a is fitted into the connector mounting portion 18a1, and the second connector seal 44b is fitted into the connector mounting portion 18c. As shown in Figures 8 and 9, because the distance L1 of the connector mounting portion 18a1 is shorter than the distance L2, the edge portions of the first connector seal 44a (the first opposing portion 44a1, the second opposing portion 44a2, and the third opposing portion 44a3) deform while fitting into the seal grooves 27a, 27b, and 27c, and the edge portions of the second connector seal 44b (the first opposing portion 44b1, the second opposing portion 44b2, and the third opposing portion 44b3) deform while fitting into the seal grooves 28a, 28b, and 28c, thereby ensuring the sealing performance of the first connector 5a and the second connector 5b.

[0050] 1 and 5 to 7, when fitting the electronic board 2 into the case body 6, the annular portion 43 of the second seal portion 42 is fitted into the seal grooves 30a, 30b, 30c, and 30d. One surface 2F of the electronic board 2 (the first surface facing the lateral wall 10) is brought into contact with the vertical support portion 23. In addition, the first surface 2F of the electronic board 2 is brought into contact with the tip of the rod 55.

[0051] The first seal portion 41 is abutted against the other surface (second surface facing the lid 7) 2U of the electronic board 2, and the lid 7 is fastened to the case body 6 with the cushioning material 56 attached to the flat surface 7a11.

[0052] As described above, when the cover 7 is fastened to the case body 6, the edges of the electronic board 2 are supported by the vertical support portions 23, and as shown in Figures 14 and 15, the periphery of the center of the electronic board 2 is supported by the rods 55. The first seal portion 41 and the second seal portion 42 of the seal member 40 are pressed by the salient portion 7b. The annular portion 43 of the second seal portion 42 deforms within the seal grooves 30a, 30b, 30c, and 30d, ensuring sealing performance.

[0053] In this way, the electronic board 2 can be fixed (attached) to the housing 3 by being sandwiched between the cover 7 and the case body 6 .

[0054] In addition, when the housing 3 does not support the electronic board 2 by sandwiching it between the case body 6 and the lid body 7, the housing 3 does not need to include both the case body 6 and the lid body 7. The housing 3 may be configured to house the electronic board 2 in a space surrounded by at least the peripheral wall 11, a first wall (side wall 10) provided on one side of the peripheral wall 11 in the height direction, a second wall (a portion corresponding to the lid body 7) provided on the other side of the peripheral wall 11 in the height direction, the peripheral wall 11, the first wall (side wall 10), and the second wall (a portion corresponding to the lid body 7).

[0055] Next, the storage section 14 will be described.

[0056] As shown in FIGS. 13 to 15, the storage section 14 includes a first storage chamber 81 and a second storage chamber 82 .

[0057] The first storage chamber 81 accommodates the power storage device 16a, and the second storage chamber 82 accommodates the electrical equipment 16b. The first storage chamber 81 and the second storage chamber 82 are divided into two chambers by the lid portion 15, as will be described later.

[0058] The storage section 14 includes a lid support section 70 that supports the lid section 15. The lid support section 70 includes a first mounting wall 71, a second mounting wall 72, and a third mounting wall 73. The first mounting wall 71 extends from the side wall 10 toward the inside of the case, and the second mounting wall 72 also extends from the side wall 10 toward the inside of the case. The first mounting wall 71 and the second mounting wall 72 are spaced apart and face each other. The third mounting wall 73 connects the first mounting wall 71 and the second mounting wall 72.

[0059] The lid support portion 70 is formed into a recessed shape by the first mounting wall 71, the second mounting wall 72, and the third mounting wall 73. The third mounting wall 73 has a plurality of holes 77 formed therein for inserting fasteners 76 such as bolts. For ease of explanation, the lid support portion 70 may be referred to as the recessed portion 70. Furthermore, the lid support portion 70 (the first mounting wall 71, the second mounting wall 72, and the third mounting wall 73) is formed to straddle the first storage chamber 81 and the second storage chamber 82.

[0060] The storage section 14 includes a plurality of side walls 79 and a plurality of mounting walls 78. The side walls 79 include a side wall 79a provided on the first storage chamber 81 side and a side wall 79b provided on the second storage chamber 82 side. The mounting walls 78 include a mounting wall 78a provided on the first storage chamber 81 side and a mounting wall 78b provided on the second storage chamber 82 side.

[0061] The side wall 79a extends from the lid support portion 70 (third mounting wall 73) toward the opposite side from the lid portion 15. The side wall 79a includes a first surface 79a1, a second surface 79a2, a third surface 79a3, and a fourth surface 79a4. The first surface 79a1 and the second surface 79a2 face each other, and the third surface 79a3 and the fourth surface 79a4 face each other. The third surface 79a3 connects one end of the first surface 79a1 to one end of the second surface 79a2, and the fourth surface 79a4 connects the other end of the first surface 79a1 to the other end of the second surface 79a2.

[0062] The mounting wall 78a is connected to the side wall 79a and is a portion on which the device 16 is placed. In this embodiment, the mounting wall 78a is connected to the first surface 79a1, the second surface 79a2, and the third surface 79a3. Therefore, the side wall 79a and the mounting wall 78a form the storage section 14 of the first storage chamber 81 in a box shape with the lid 15 side open, i.e., in a concave shape, and can store the rectangular power storage device 16a.

[0063] The side wall 79b extends from the lid support portion 70 (third mounting wall 73) toward the opposite side from the lid portion 15 and has a cylindrical shape. The mounting wall 78b protrudes radially inward from the side wall 79b and is formed in a circular shape. A cylindrical holder 75 is connected to the radially inward end of the mounting wall 78b. Therefore, the side wall 79b and the mounting wall 78b form the accommodation portion 14 of the second accommodation chamber 82 into a cylindrical shape that is open on the lid portion 15 side and can accommodate a cylindrical electric device 16b. Specifically, the electric device 16b includes a cylindrical main body 16b1 and a sealing material 16b2 attached to the main body 16b1. The electric device 16b is supported by fitting the sealing material 16b2 between the side wall 79b and the mounting wall 78b.

[0064] The lid portion 15 is a member capable of covering the first storage chamber 81 and the second storage chamber 82. The lid portion 15 is formed in a plate shape that conforms to the lid support portion 70 in a plan view and is attachable (fittable to) the lid support portion 70. The lid portion 15 includes a first plate portion 15a that faces the third mounting wall 73 and a second plate portion 15b that extends from the first plate portion 15a toward the peripheral wall 11. In other words, the second plate portion 15b faces the fourth vertical wall 20d and overlaps with it in the vertical direction.

[0065] Protrusions 15c and 15d protruding from lid portion 15 are formed on the inner surface of lid portion 15. Therefore, when lid portion 15 is fitted into lid support portion 70, protrusions 15c and 15d abut against third mounting wall 73, so that lid portion 15 is fitted into first mounting wall 71 and second mounting wall 72 while being spaced apart from third mounting wall 73.

[0066] 13 and 15 , in a plan view, the third surface 79a3 of the side wall 79a and the side wall 79b are horizontally spaced apart. That is, in the third mounting wall 73, the portion between the third surface 79a3 and the side wall 79b is a portion (partition area A1) capable of separating the first storage chamber 81 and the second storage chamber 82. When the lid 15 is attached to the lid support part 70, the protrusion 15c abuts against the partition area of ​​the third mounting wall 73, and therefore functions as a partition separating the first storage chamber 81 and the second storage chamber 82. Furthermore, the protrusion 15c presses against the sealing material 16b2 attached to the main body 16b1, thereby also supporting the electrical device.

[0067] Furthermore, a first waterproof member 88 is provided on the inner surface of the lid portion 15, and is positioned closer to the first storage chamber 81 than the protrusion 15c (partition portion). The first waterproof member 88 is annular and is located outward from the side wall 79a of the first storage chamber 81 in a plan view. The first waterproof member 88 is also in contact with at least the partition area A1 of the third mounting wall 73. A second waterproof member 89 is provided on the lid portion 15, separate from the first waterproof member 88, and is capable of contacting the power storage device 16a. The second waterproof member 89 is annular and smaller than the first waterproof member 88 in a plan view. Therefore, the first storage chamber 81 is waterproofed by two waterproof members (the first waterproof member 88 and the second waterproof member 89).

[0068] The housing 3 is equipped with a discharge structure 90 that discharges foreign matter that has entered the storage section 14. The foreign matter includes sludge, water, dust, and the like. In particular, the discharge structure 90 is designed to discharge sludge and water that contain moisture. The discharge structure 90 can discharge foreign matter from the storage section 14 to the first wall side (side wall 10 side), and can also discharge foreign matter from the storage section 14 to the peripheral wall 11 side. In other words, the discharge structure 90 can discharge foreign matter to both the side wall 10 side and the peripheral wall 11 side.

[0069] 3, 15, and 16 show an example of the discharge structure 90, and FIGS. 17 and 18 show modified examples of the discharge structure 90. In FIG.

[0070] 3, 15, and 16 includes a communication passage 98 and a second through hole 95 that communicate between the peripheral wall 11 and the storage portion 14. The communication passage 98 includes a recess 70 that extends to the peripheral wall 11.

[0071] The communication passage 98 is formed by forming the fourth vertical wall 20d in a stepped shape, connecting the end of the fourth vertical wall 20d on the horizontal wall 10 side to the third mounting wall 73 of the second storage chamber 82, and separating the fourth vertical wall 20d from the second plate portion 15b. Specifically, the fourth vertical wall 20d includes a first portion 91 connected to the third mounting wall 73 of the second storage chamber 82 and extending toward the lid 7 (second wall), a second portion 92 connected to the first portion 91 and bending horizontally midway, and a third portion 93 connected to the second portion 92 and into which the lid 7 (second wall) fits. The first portion 91 and the second plate portion 15b are separated, allowing foreign matter (wastewater) and the like from the storage chamber 14 to be discharged toward the fourth vertical wall 20d (peripheral wall 11). The second through-hole 95 is a through-hole provided in the lid portion 15. The second through-hole 95 is a hole that penetrates the first plate portion 15a but does not reach the second plate portion 15b. The second through-hole 95 communicates with the second storage chamber 82 and communicates from the interior of the storage portion 14 to the side wall 10. According to the discharge structure 90 in Figures 3, 15, and 16, foreign matter is discharged to the side wall 10 through the second through-hole 95 and to the fourth vertical wall 20d side (the side of the peripheral wall 11) through the communication passage 98.

[0072] The discharge structure 90 in FIGS. 17 and 18 includes a first through hole 94. The first through hole 94 is a hole formed through the lid portion 15, and communicates from the interior of the storage portion 14 to the lateral wall 10 and from the storage portion 14 to the peripheral wall 11. For example, the first through hole 94 extends from the first plate portion 15a to the second plate portion 15b. The end of the second plate portion 15b on the side of the fourth vertical wall 20d is in contact with the fourth vertical wall 20d, closing the fourth vertical wall 20d side of the storage portion 14. According to the discharge structure 90 in FIGS. 17 and 18, foreign matter is discharged through the first through hole 94 to the lateral wall 10 and the fourth vertical wall 20d (the peripheral wall 11).

[0073] Although the storage section 14 is provided in the side wall (first wall) 10, it may be provided in the second wall opposing the side wall (first wall) 10, i.e., the wall portion corresponding to the lid body 7. Although the discharge structure 90 is provided in the side wall (first wall) 10, it may be provided in the second wall opposing the side wall (first wall) 10, i.e., the wall portion corresponding to the lid body 7. In this case, the first through hole 94 is a hole that communicates with at least one of the first wall side and the second wall side and that communicates from the storage section 14 to the peripheral wall 11 side. The second through hole 95 is a hole that communicates with at least one of the first wall side and the second wall side.

[0074] In the electronic device 1, there are cases where some of the multiple connector mounting portions 18 are not provided with connectors 5. As shown in Figures 25 and 32, it is possible to attach a cover 60 to an empty mounting portion, which is a connector mounting portion 18 where no connector 5 is located (no connector 5 is mounted).

[0075] The cover 60 will now be described.

[0076] 25 and 32, there are two types of covers 60: a cover 60a that is attached to the electronic board 2 in place of the connector 5 that is attached to the electronic board 2, and a cover 60b that is attached to the second connector 5b in place of the second connector 5b. The covers 60a and 60b are different in size but have roughly the same structure, so only the common structure will be described.

[0077] As shown in Figures 19 to 32, the cover 60 (60a, 60b) includes a main body 61 and an attachment portion 62. The main body 61 is a portion that is located in and covers the empty attachment portion. The main body 61 includes an abutting portion 61a and an attachment portion 61b. The abutting portion 61a and the attachment portion 61b are made of an elastic material such as rubber. The abutting portion 61a is formed in an annular shape. The attachment portion 61b is a rectangular parallelepiped, and its outer side is connected to the abutting portion 61a. The attachment portion 61b includes a first portion 61b1, a second portion 61b2, a third portion 61b3, a fourth portion 61b4, and a fifth portion 61b5.

[0078] The first portion 61b1, the second portion 61b2, the third portion 61b3, the fourth portion 61b4, and the fifth portion 61b5 are plate-shaped. The first portion 61b1 and the second portion 61b2 are spaced apart and face each other. The third portion 61b3 and the fourth portion 61b4 are spaced apart and face each other. The abutting portion 61a is connected to each of the first portion 61b1, the second portion 61b2, the third portion 61b3, and the fourth portion 61b4. The fifth portion 61b5 connects the first portion 61b1, the second portion 61b2, the third portion 61b3, and the fourth portion 61b4 on the side opposite to the abutting portion 61a.

[0079] The mounting portion 61b is provided with a fitting portion 63 into which the connector seal portion 44 of the seal member 40 is fitted.

The protrusions 69a, 69b are spaced apart from each other, and the protrusion 48 formed on the connector seal portion 44 is fitted between the protrusions 69a, 69b.

[0080] 30 and 31 , when the cover 60a is inserted into the insertion portion 46 of the first connector seal portion 44a, the outer surface of the case of the first connector seal portion 44a comes into contact with the abutment portion 61a. The portions (protrusions 48) formed on the first opposing portion 44a1, the second opposing portion 44a2, the third opposing portion 44a3, and the fourth opposing portion 44a4 opposing the third opposing portion 44a3 are fitted between pairs of protrusions 69a, 69b formed on the first portion 61b1, the second portion 61b2, the third portion 61b3, and the fourth portion 61b4, respectively.

[0081] 23 and 24 , when the cover 60b is inserted into the insertion portion 47 of the second connector seal portion 44b, the outer surface of the case of the second connector seal portion 44b comes into contact with the abutment portion 61a. The portions (protrusions 48) formed on the first opposing portion 44b1, the second opposing portion 44b2, the third opposing portion 44b3, and the fourth opposing portion 44b4 opposing the third opposing portion 44b3 are fitted between pairs of protrusions 69a, 69b formed on the first portion 61b1, the second portion 61b2, the third portion 61b3, and the fourth portion 61b4, respectively.

[0082] The mounting portion 62 is a portion that is connected to the main body 61 and can be mounted on the electronic board 2. The mounting portion 62 includes a board mounting portion 62a that is mounted on the electronic board 2 and a housing mounting portion 63b that is mounted on the housing 3. The board mounting portion 62a and the housing mounting portion 63b are attached to the main body 61 inside the case.

[0083] More specifically, at least two board mounting portions 62a are provided on the side wall 10 side of the mounting portion 61b. One board mounting portion 62a1 and the other board mounting portion 62a2 are spaced apart. One board mounting portion 62a1 is attached to the first portion 61b1, the third portion 61b3, and the fifth portion 61b5. The other board mounting portion 62a2 is attached to the second portion 61b2, the third portion 61b3, and the fifth portion 61b5. The board mounting portions 62a (62a1, 62a2) are formed with holes 66 into which fasteners 65 such as bolts are inserted.

[0084] At least two housing attachment portions 63b are provided on the side wall 10 side of the mounting portion 61b. The housing attachment portions 63b1 and 63b2 are spaced apart. The housing attachment portions 63b1 and 63b2 are attached to the first portion 61b1, the fourth portion 61b4, and the fifth portion 61b5. The other housing attachment portion 63b2 is attached to the second portion 61b2, the fourth portion 61b4, and the fifth portion 61b5. The housing attachment portions 63b (63a1 and 63a2) are formed with holes 67 into which fasteners 65 such as bolts are inserted.

[0085] As shown in FIG. 25 , when the connector mounting portion 18c is an empty mounting portion and a cover 60b is to be attached to the empty mounting portion, fasteners 65 are passed through holes 125 formed in the electronic board 2 and fastened to holes 66 of the board mounting portions 62a (62a1, 62a2), thereby attaching the cover 60b to the electronic board 2. The electronic board 2 with the attached cover 60b is then fitted into the case main body 6, and the cover 60b is fitted into the connector mounting portion 18c. The fasteners 65 are passed through the housing mounting portions 63b (63a1, 63a2) of the cover 60b and fastened to fasteners 126 provided on the inner surface of the case main body 6, thereby attaching the cover 60b to the housing 3. The electronic board 2 has through-holes 120 formed therein through which the fasteners 65 can be inserted from the lid 7 side when attaching the cover 60b to the housing 3. The through portion 120 is formed by cutting out the electronic board 2 so as to avoid the housing mounting portion 63b (63a1, 63a2).

[0086] As shown in FIG. 32 , when the connector mounting portion 18a1 is an empty mounting portion and the cover 60a is to be attached to the empty mounting portion, fasteners 65 are passed through holes 125 formed in the electronic board 2 and fastened to holes 66 of the board mounting portions 62a (62a1, 62a2), thereby attaching the cover 60a to the electronic board 2.
