[0009] The mobile charging device according to the embodiment of the present disclosure will be described with reference to the drawings. The drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios.

[0010] (Present embodiment) (1) Overview An outline of a charging device for a mobile body 1 according to this embodiment will be described below with reference to FIGS.

[0011] As shown in FIGS. 1 and 2, the mobile body charging device 1 according to this embodiment includes a filter board 210, a converter board 220, a control board 230, a control power supply board 240, a housing 3, and a panel 4.

[0012] The filter board 210 has a first filter circuit 21a (see FIG. 3) electrically connected to the external power supply A1. The first filter circuit 21a corresponds to the filter circuit of the present invention. The converter board 220 has a converter circuit 22 (see FIG. 3) that converts power supplied from the external power supply via the first filter circuit 21a. The control board 230 has at least a control circuit 23 (see FIG. 3) that controls the converter circuit 22. The control power supply board 240 has at least a control power supply circuit 24 (see FIG. 3) that supplies a control voltage to the control circuit 23. As shown in FIG. 2, the housing 3 houses the filter board 210, the converter board 220, the control board 230, and the control power supply board 240. The panel 4 opens and closes an opening 31 in the housing 3.

[0013] 2, the housing 3 has a bottom surface 320, a first space S1, and a second space S2. The bottom surface 320 faces the opening 31. The first space S1 houses the filter substrate 210 and the converter substrate 220. The second space S2 houses the control substrate 230 and the control power supply substrate 240. The first space S1 and the second space S2 are aligned along an opposing direction D1, which is the direction in which the opening 31 and the bottom surface 320 face each other. The second space S2 is located closer to the opening 31 than the first space S1 in the opposing direction D1.

[0014] As described above, the mobile body charging device 1 of this embodiment has the advantage that the filter board 210, the converter board 220, the control board 230, and the control power supply board 240 can be arranged three-dimensionally inside the housing 3. As a result, the mobile body charging device 1 of this embodiment has the advantage that it can be made smaller.

[0015] (2) Detailed configuration (2-1) Overall The detailed configuration of the mobile body charging device 1 of this embodiment will be described below with reference to Figs. 1 to 10. In the following description, the mobile body charging device 1 is assumed to be installed on a horizontal installation surface X1 as shown in Fig. 1, and the direction in which the installation surface X1 faces (a direction perpendicular to the installation surface X1 and away from the installation surface X1) is defined as the upward direction. The opposite of the upward direction is defined as the downward direction. The upward and downward directions may be collectively referred to as the vertical direction D2.

[0016] The direction in which the housing 3 and the panel 4 are lined up is defined as the front-to-rear direction, the panel 4 side as viewed from the housing 3 is defined as the front direction, and the housing 3 side as viewed from the panel 4 is defined as the rear direction. The front-to-rear direction corresponds to the facing direction D1 of the present invention, which will be described later.

[0017] 1 is defined as the left-right direction of the mobile object charging device 1. The left-right direction corresponds to a width direction D3 of the present invention, which will be described later. The width direction D3 intersects with the up-down direction D2 and the facing direction D1, and is perpendicular to them here.

[0018] However, the definition of these directions is not intended to limit the manner in which the mobile object charging device 1 is used.

[0019] The mobile body charging device 1 of this embodiment is a device for supplying power to charge the storage battery B12 (see FIG. 3) of the mobile body B1. In this embodiment, the mobile body charging device 1 is a dedicated charger for the mobile body B1. In this embodiment, the charger is a normal charger, but it may also be a rapid charger.

[0020] The "mobile body B1" in this disclosure includes a storage battery B12 and moves using electrical energy stored in the storage battery B12. In this embodiment, the mobile body B1 is an electric vehicle. As shown in FIG. 3, the mobile body B1 includes the storage battery B12 and a charging circuit B11. The storage battery B12 is mounted on the mobile body B1 and is used as a power source for the mobile body B1. The charging circuit B11 is a circuit that receives power from the mobile body charging device 1 and charges the storage battery B12.

[0021] In this embodiment, the mobile object B1 is an electric vehicle, but is not limited to this and may be, for example, a plug-in hybrid vehicle that runs on a combination of engine output and electric motor output, an electric cart, an electric two-wheeled vehicle, an electric three-wheeled vehicle, an electric four-wheeled buggy, etc. Here, "electric two-wheeled vehicle" includes a motorcycle, an electric scooter, and an electrically assisted two-wheeled vehicle. Furthermore, "electric three-wheeled vehicle" includes an electric scooter and an electrically assisted three-wheeled vehicle. Furthermore, the mobile object B1 also includes flying objects such as drones and aircraft.

[0022] 3 and 4, the mobile body charging device 1 of this embodiment includes, in addition to the filter board 210, the converter board 220, the control board 230, the control power supply board 240, the housing 3, and the panel 4, three electronic components 5, three cables 6, a first fixed base 7, a second fixed base 8, a base 91, a resin cover 92, an operation display panel 93, a duct 94, a cable holder 951, a cable guide 953, an inner lid 96, a terminal base 97, and a heat sink 98. The first fixed base 7 corresponds to the fixed base of the present invention.

[0023] 3, the mobile object charging device 1 of this embodiment includes three electronic components 5: a communication terminal 5a, a mobile object terminal 5b, and a fan 5c. In the following description, when the communication terminal 5a, the mobile object terminal 5b, and the fan 5c are not distinguished from each other, they will be collectively referred to as the "electronic components 5."

[0024] (2-2) Housing 2 and 4, the housing 3 is formed in the shape of a hollow rectangular box having an opening 31 on the front side. The housing 3 has a bottom surface 320 (see FIG. 2) facing the opening 31. The facing direction D1 shown in FIG. 2 is the direction in which the opening 31 and the bottom surface 320 face each other. In other words, the opening 31 and the bottom surface 320 face each other along the front-rear direction.

[0025] 2, the housing 3 has a housing main body 30, a lower plate 34, and an upper plate 35. The housing 3 is made of, for example, metal.

[0026] As shown in FIGS. 4 and 5, the housing main body 30 has a rear plate 32 and two side plates 33. The rear plate 32 and the two side plates 33 are each a rectangular plate. The surface of the rear plate 32 on the opening 31 side (i.e., the front side) is a bottom surface 320. As shown in FIG. 6, each of the two side plates 33 protrudes from a side edge 321 of the rear plate 32 toward the opening 31 along the facing direction D1. In other words, each of the two side plates 33 protrudes from a side edge 321 of the bottom surface 320 toward the opening 31 along the facing direction D1. The side edges 321 here refer to the left and right side edges of the bottom surface 320. In other words, the housing main body 30 is formed in a substantially U-shape when viewed from above.

[0027] The lower plate 34 and the upper plate 35 are rectangular plates. As shown in Fig. 2, the lower plate 34 is arranged so that the rear end of the lower plate 34 is connected to the lower end of the housing main body 30. On the other hand, the upper plate 35 is arranged so that the rear end of the upper plate 35 is connected to the upper end of the housing main body 30. As shown in Fig. 4, the lower plate 34 is provided with ventilation holes 341.

[0028] The panel 4 opens and closes the opening 31. More specifically, the panel 4 is detachably attached to the front side of the housing 3 so as to close the opening 31 (see FIG. 2). For example, the panel 4 is attached to the housing 3 with screws. The panel 4 in this embodiment has a rectangular plate shape. The panel 4 is made of, for example, metal.

[0029] The housing 3 houses the filter substrate 210, the converter substrate 220, the control substrate 230, and the control power supply substrate 240. More specifically, as shown in Fig. 2, the housing 3 has a first space S1 that houses the filter substrate 210 and the converter substrate 220, and a second space S2 that houses the control substrate 230 and the control power supply substrate 240.

[0030] The second space S2 is located closer to the opening 31 (i.e., closer to the front) than the first space S1 in the facing direction D1. In other words, the first space S1 is located closer to the bottom surface 320 (i.e., closer to the rear) than the second space S2 in the facing direction D1. More specifically, the second space S2 is located obliquely upward and frontward from the first space S1 in the space surrounded by the housing 3 and the panel 4. In other words, the first space S1 is located obliquely downward and rearward from the second space S2 in the space surrounded by the housing 3 and the panel 4.

[0031] (2-3) Power supply section The power supply unit 2 is connected to an external power source A1 via a power connector and receives power from the power source. The power supply unit 2 supplies power that can be charged to a storage battery B12 of the mobile object B1. The external power source A1 is, for example, a DC power source such as a power generation device (such as a solar power generation device) or a storage battery installed in a facility (such as a home, factory, commercial building, office building, hospital, etc.). Alternatively, the external power source A1 may be, for example, an AC power source such as a commercial AC power source.

[0032] The power supply unit 2 includes a filter board 210, a converter board 220, a control board 230, a control power supply board 240, and a plurality of circuit components included in the above-mentioned plurality of boards. The filter board 210 includes a first filter circuit 21a and a second filter circuit 21b. The converter board 220 includes a converter circuit 22. The control board 230 includes a control circuit 23 and an input unit 25. The control power supply board 240 includes a control power supply circuit 24. In this embodiment, the filter board 210 further includes a relay 26 in addition to the first filter circuit 21a and the second filter circuit 21b. Note that the converter board 220 may include the relay 26 instead of the filter board 210.

[0033] In short, as shown in FIG. 3, the power supply unit 2 includes a first filter circuit 21a, a second filter circuit 21b, a converter circuit 22, a control circuit 23, a control power supply circuit 24, an input unit 25, and a relay 26.

[0034] The first filter circuit 21a is electrically connected to the external power supply A1. The first filter circuit 21a is provided between the external power supply A1 and the converter circuit 22. More specifically, the first filter circuit 21a is provided between a power connector electrically connected to the external power supply A1 and the converter circuit 22. The first filter circuit 21a outputs a target frequency component of the power supplied from the external power supply A1 to the converter circuit 22. Specifically, the first filter circuit 21a attenuates components other than the target frequency component of the power supplied from the external power supply A1, and outputs the target frequency component to the converter circuit 22.

[0035] The converter circuit 22 converts the power supplied from the external power source A1 via the first filter circuit 21a. That is, the converter circuit 22 converts the power supplied from the external power source A1 from which the target frequency component has been extracted by the first filter circuit 21a. Here, "power conversion" refers to converting at least one of the voltage, current, frequency, phase, and number of phases supplied from the external power source A1. For example, when the power supplied from the external power source A1 is DC power, the converter circuit 22 converts it into DC power with a voltage suitable for the storage battery B12 of the mobile object B1. In other words, when the power supplied from the external power source A1 is DC power, the converter circuit 22 performs DC / DC conversion. Furthermore, when the power supplied from the external power source A1 is AC power, the converter circuit 22 converts it into DC power with a voltage suitable for the storage battery B12 of the mobile object B1. In other words, when the power supplied from the external power source A1 is AC power, the converter circuit 22 performs AC / DC conversion.

[0036] The second filter circuit 21b is electrically connected to the moving object B1. In this embodiment, the second filter circuit 21b is electrically connected to the moving object B1 via a moving object terminal 5b (described later). The second filter circuit 21b is provided between the converter circuit 22 and the moving object terminal 5b. The second filter circuit 21b outputs a target frequency component of the power converted by the converter circuit 22 to the moving object B1. Specifically, the second filter circuit 21b attenuates components other than the target frequency component of the power converted by the converter circuit 22, and outputs the target frequency component to the moving object B1. The power output by the second filter circuit 21b is supplied to the moving object B1 via the moving object terminal 5b and the moving object cable C1.

[0037] The control circuit 23 controls the converter circuit 22. For example, based on information about the storage battery B12 obtained from the mobile object B1 via the mobile object cable C1, the control circuit 23 controls the converter circuit 22 so that the converter circuit 22 receives power from the external power source A1 and outputs a current suitable for the storage battery B12. As an example, the control circuit 23 controls the current value output by the converter circuit 22 in accordance with the difference between the actual measured value of the amount of stored power in the storage battery B12 and the target value of the amount of stored power.

[0038] The control circuit 23 is mainly composed of a computer system including a memory and a processor. That is, the functions of the control circuit 23 are realized by the processor executing a program stored in the memory of the computer system. The program may be pre-stored in the memory, provided via a telecommunications line such as the Internet, or provided by being recorded on a non-transitory recording medium such as a memory card.

[0039] The control power supply circuit 24 supplies a control voltage to the control circuit 23. The "control voltage" here refers to a voltage necessary for the operation of the control circuit 23. The control power supply circuit 24 may supply a control voltage to the converter circuit 22 in addition to the control circuit 23.

[0040] The input unit 25 receives a charge command and a stop command from the operation display panel 93. Note that the input unit 25 may receive the charge command and the stop command from an external control device such as a remote controller or a smartphone by communication (wired communication or wireless communication).

[0041] The relay 26 is provided in a power supply path to the storage battery B12. In this embodiment, the relay 26 is provided in the filter substrate 210 between a power connector electrically connected to the external power source A1 and the first filter circuit 21a. As a result, when the relay 26 is on (conductive state), power can be supplied from the external power source A1 to the storage battery B12 of the mobile object B1. On the other hand, when the relay 26 is off (cut-off state), power is not supplied from the external power source A1 to the storage battery B12 of the mobile object B1. The relay 26 may be a mechanical relay having mechanical contacts or a semiconductor relay without mechanical contacts as long as it can be controlled by the control circuit 23.

[0042] That is, the control circuit 23 further controls the supply of electricity from the mobile object charging device 1 to the mobile object B1. Here, the control circuit 23 controls the supply of electricity to the mobile object B1 by driving the relay 26 in accordance with the charge command and stop command received by the input unit 25. Basically, when the input unit 25 receives the charge command, the control circuit 23 turns on (conductive state) the relay 26 to conduct the electrical path from the power supply unit 2 to the mobile object B1, thereby charging the storage battery B12. On the other hand, when the input unit 25 receives a stop command, the control circuit 23 turns off (interrupted state) the relay 26 to interrupt the electrical path from the power supply unit 2 to the mobile object B1, thereby stopping the charging of the storage battery B12.

[0043] However, if the storage battery B12 is in a state where it cannot be charged, such as when the storage battery B12 is fully charged, then the storage battery B12 will not be charged. Similarly, if the mobile object cable C1 is not connected to the mobile object B1 and the mobile object charging device 1 and the mobile object B1 are not electrically connected, then the storage battery B12 will not be charged. In this manner, if the storage battery B12 is in a state where it cannot be charged, even if the input unit 25 receives a charge command, the control circuit 23 will not turn on (conductive state) the relay 26 and will cut off the electrical path from the power supply unit 2 to the mobile object B1. That is, the control circuit 23 obtains information about the status of the storage battery B12 and information about whether the mobile object charging device 1 and the mobile object B1 are electrically connected, and further controls the supply of electricity to the mobile object B1 based on the information.

[0044] (2-4) 1st fixed stand 7 and 8, the first fixed base 7 has a main board 71, two first extensions 721a and 721b, two second extensions 722a and 722b, a third extension 723, and two protrusions 73a and 73b. The first extensions 721a and 721b correspond to the extensions of the present invention. FIG. 8 is a front view of the mobile object charging device 1 with the panel 4 and inner lid 96 removed.

[0045] (main plate) The main board 71 has a substantially rectangular plate shape. As shown in Fig. 6, the thickness direction of the main board 71 is along the opposing direction D1. A control board 230 and a control power supply board 240 are fixed to the main board 71. More specifically, the control board 230 and the control power supply board 240 are fixed to the front surface of the main board 71.

[0046] The main board 71 is housed in the housing 3. As shown in Fig. 2 and Fig. 6, the main board 71 separates a first space S1 and a second space S2 inside the housing 3. That is, the first space S1 is located behind the main board 71 in the facing direction D1. On the other hand, the second space S2 is located in front of the main board 71 in the facing direction D1.

[0047] As shown in FIG. 2 , the control board 230 is fixed to the upper part of the front surface of the main board 71, and the control power supply board 240 is fixed to the lower part of the front surface of the main board 71. That is, the control board 230 is disposed in the upper part of the second space S2, and the control power supply board 240 is disposed in the lower part of the second space S2. In other words, the control board 230 is disposed above the control power supply board 240 in the second space S2. If the inside of the housing 3 is called the storage space, the temperature in the upper part of the storage space tends to be higher than the temperature in the lower part of the storage space. However, in this embodiment, the control power supply board 240 is disposed in the lower part of the storage space where the temperature is relatively low, which can improve the reliability of the control power supply board 240. This has the advantage of improving the operational reliability of the power supply unit 2.

[0048] (1st extension part) As shown in Fig. 6, the two first extending portions 721a, 721b extend from side edges 711a, 711b of the main board 71 along the up-down direction D2 toward the opening 31 (front side) between the control power supply board 240 and the side plate 33 in the width direction D3. The side edge 711a is the right edge of the main board 71, and the side edge 711b is the left edge of the main board 71. The first extending portions 721a, 721b extend from lower portions of the side edges 711a, 711b of the main board 71 along the up-down direction D2 toward the opening 31. As shown in Fig. 8, the "lower portions of the side edges 711a, 711b of the main board 71" refer to portions of the side edges 711a, 711b of the main board 71 that are located between the control power supply board 240 and the side plate 33 in the width direction D3. That is, the two first extending portions 721a, 721b are provided below the main plate 71. The two first extending portions 721a, 721b are in the shape of a substantially rectangular plate. The two first extending portions 721a, 721b intersect with the main plate 71 (here, perpendicularly).

[0049] 7, the two first extending portions 721a, 721b face each other in the left-right direction (width direction D3). The right first extending portion 721a extends from the right side edge 711a of the main board 71 toward the opening 31 between the control power supply board 240 and the side plate 33 in the width direction D3. Similarly, the left first extending portion 721b extends from the left side edge 711b of the main board 71 toward the opening 31 (front side) between the control power supply board 240 and the side plate 33 in the width direction D3.

[0050] An attachment plate 74a is provided at the front end of the first extension portion 721a. Similarly, an attachment plate 74b is provided at the front end of the first extension portion 721b. The inner lid 96 is attached to the attachment plates 74a and 74b. Here, the attachment plates 74a and 74b are formed by curving the front sides of the first extension portions 721a and 721b outward. The "outward direction" here refers to the direction from the control power supply board 240 toward the side plate 33 in the width direction D3. In other words, the attachment plate 74a is formed by curving the front side of the first extension portion 721a rightward. On the other hand, the attachment plate 74b is formed by curving the front side of the first extension portion 721b leftward.

[0051] (2nd extension part) 7 and 8, the two second extending portions 722a, 722b extend from the side edges 711a, 711b of the main plate 71 along the up-down direction D2 toward the opening 31 between the control board 230 and the side plate 33 in the width direction D3. In other words, the two second extending portions 722a, 722b extend from upper portions of the side edges 711a, 711b of the main plate 71 along the up-down direction D2 toward the opening 31. Here, "upper portions of the side edges 711a, 711b of the main plate 71" refers to portions of the side edges 711a, 711b of the main plate 71 that are located between the control board 230 and the side plate 33 in the width direction D3, as shown in FIG. 8. In other words, the two second extending portions 722a, 722b are provided on the upper side of the main plate 71. The two second extending portions 722a and 722b are substantially rectangular plate-shaped and intersect with the main plate 71 (here, perpendicularly).

[0052] The second extension portions 722a, 722b are provided at different positions on the main plate 71 compared to the first extension portions 721a, 721b. More specifically, the first extension portion 721a is provided below the side edge 711a of the main plate 71, whereas the second extension portion 722a is provided above the side edge 711a of the main plate 71. Similarly, the first extension portion 721b is provided below the side edge 711b of the main plate 71, whereas the second extension portion 722b is provided above the side edge 711b of the main plate 71.

[0053] 7, the second extending portions 722a and 722b face each other in the left-right direction (width direction D3). The right second extending portion 722b extends from the right side edge 711a of the main board 71 toward the opening 31 between the control board 230 and the side plate 33 in the width direction D3. Similarly, the left second extending portion 722b extends from the left side edge 711b of the main board 71 toward the opening 31 (front side) between the control board 230 and the side plate 33 in the width direction D3.

[0054] An attachment plate 74c is provided at the front end of the second extension portion 722a. Similarly, an attachment plate 74d is provided at the front end of the second extension portion 722b. An inner lid 96 is attached to the attachment plates 74c and 74d. Here, the attachment plates 74c and 74d are formed by curving the front sides of the second extension portions 722a and 722b outward. The "outward direction" here refers to the direction from the control board 230 toward the side plate 33 in the width direction D3. In other words, the attachment plate 74c is formed by curving the front side of the second extension portion 722a toward the right. On the other hand, the attachment plate 74d is formed by curving the front side of the second extension portion 722b toward the left.

[0055] (3rd extension part) 7 and 8, the third extension portion 723 extends from the upper side edge of the main board 71 toward the opening 31 above the control board 230 in the vertical direction D2. The third extension portion 723 has a substantially rectangular plate shape. The third extension portion 723 intersects with the main board 71 (here, perpendicularly).

[0056] An attachment plate 74e is provided at the front end of the third extending portion 723. The inner lid 96 is attached to the attachment plate 74e. Here, the attachment plate 74e is formed by curving the front side of the third extending portion 723 downward.

[0057] (protrusion) As shown in FIG. 8, the protrusions 73a and 73b are provided on the main plate 71 at positions opposing each other in the left-right direction (width direction D3). As shown in FIGS. 7 and 8, the protrusions 73a and 73b are adjacent to the upper ends of the first extending portions 721a and 721b, and protrude from the side edges 711a and 711b of the main plate 71 along the width direction D3. More specifically, the protrusion 73a is adjacent to the upper end of the first extending portion 721a and protrudes from the right side edge 711a of the main plate 71 along the width direction D3. On the other hand, the protrusion 73b is adjacent to the upper end of the first extending portion 721b and protrudes from the left side edge 711b of the main plate 71 along the width direction D3. The protrusion 73a is provided on the right side edge 711a of the main plate 71, between the first extending portion 721a and the second extending portion 722a. Similarly, the protrusion 73b is provided on the left side edge 711b of the main plate 71 between the first extension 721b and the second extension 722b.

[0058] The protrusions 73a and 73b are generally rectangular plate-shaped. The thickness direction of the protrusions 73a and 73b is along the facing direction D1. As shown in FIG. 7, the protrusion 73a is located rearward of the mounting plate 74a in the front-rear direction (facing direction D1). That is, when the inner lid 96 is attached to the mounting plate 74a, a space is formed between the protrusion 73a and the inner lid 96 in the facing direction D1. Similarly, the protrusion 73b is located rearward of the mounting plate 74b in the front-rear direction (facing direction D1). That is, when the inner lid 96 is attached to the mounting plate 74b, a space is formed between the protrusion 73b and the inner lid 96 in the facing direction D1.

[0059] The lower surfaces of the protrusions 73a and 73b are fixed to third intervening members 823a and 823b of the second fixed base 8, which will be described later.

[0060] (2-5)Second fixed stand 9, the second fixed base 8 has a main board 81, two first intervening members 821a and 821b, a second intervening member 822, two third intervening members 823a and 823b, and a fourth intervening member 824. Hereinafter, when there is no need to distinguish between the two first intervening members 821a and 821b, the second intervening member 822, the two third intervening members 823a and 823b, and the fourth intervening member 824, they will be collectively referred to as intervening members 82.

[0061] (main plate) The main board 81 has a rectangular plate shape. As shown in Fig. 2, the thickness direction of the main board 81 is along the opposing direction D1. The filter substrate 210 and the converter substrate 220 are fixed to the main board 81. More specifically, the filter substrate 210 and the converter substrate 220 are fixed to the front surface of the main board 81.

[0062] 2 and 6, the main board 81 is housed in the housing 3. The main board 81 is disposed inside the housing 3, behind the main board 71 of the first fixed base 7. The first space S1 is a space sandwiched between the main board 71 of the first fixed base 7 and the main board 81 of the second fixed base 8 in the opposing direction D1. In other words, the first space S1 is located in front of the main board 81.

[0063] As shown in FIG. 2 , the converter board 220 is fixed to an upper part of the front surface of the main board 81, and the filter board 210 is fixed to a lower part of the front surface of the main board 81. That is, the converter board 220 is disposed in an upper part of the first space S1, and the filter board 210 is disposed in a lower part of the first space S1. In other words, the converter board 220 is disposed above the filter board 210 in the first space S1. The heat generated by the converter board 220 tends to be greater than the heat generated by the filter board 210. Therefore, disposing the converter board 220 above the filter board 210 has the advantage of improving the reliability of the operation of the power supply unit 2. Here, the "heat generated by the converter board 220" refers mainly to heat generated by the operation of the converter circuit 22. Furthermore, the "heat generated by the filter board 210" refers mainly to heat generated by the operation of the first filter circuit 21a and the second filter circuit 21b.

[0064] 5, a heat sink 98 and a fan 5c are provided on the rear surface of the main board 81. More specifically, the heat sink 98 is provided on the upper part of the rear surface of the main board 81, and the fan 5c is provided on the lower part of the rear surface of the main board 81.

[0065] The heat sink 98 is thermally connected to the filter substrate 210 and the converter substrate 220 via the main board 81. Therefore, the heat sink 98 dissipates heat generated in the filter substrate 210 and the converter substrate 220 to the rear side of the main board 81.

[0066] The fan 5c draws air into the housing 3. More specifically, the fan 5c draws air into the housing 3 through the ventilation holes 341 in the housing 3 so that heat emitted by the heat sink 98 is discharged to the outside of the mobile object charging device 1 through the duct 94. In this embodiment, as shown in FIGS. 6 and 8, two fans 5c are provided on the lower part of the rear surface of the main board 81.

[0067] Two insertion holes 84, through which a third cable 6c (described later) is inserted, are provided in the lower part of the main board 81. In this embodiment, the third cable 6c is routed from the front side of the main board 81 to the rear side of the main board 81 by being inserted through the two insertion holes 84.

[0068] (intervening member) Intermediate member 82 is a member that is disposed between main plate 71 of first fixed base 7 and main plate 81 of second fixed base 8 in facing direction D1. Therefore, intermediate member 82 functions as a spacer that maintains the distance in facing direction D1 between main plate 71 of first fixed base 7 and main plate 81 of second fixed base 8. Intermediate member 82 is a plate member.

[0069] 9, the first intervening members 821a and 821b face each other in the left-right direction (width direction D3). Each of the first intervening members 821a and 821b extends (in the forward direction) from a side edge of the main plate 81 of the second fixed base 8 along the up-down direction D2 toward the first fixed base 7 between the filter substrate 210 and the side plate 33 in the width direction D3. More specifically, the right first intervening member 821a extends from a right side edge of the main plate 81 of the second fixed base 8 along the up-down direction D2 toward the first fixed base 7 between the filter substrate 210 and the side plate 33 in the width direction D3. Meanwhile, the left first intervening member 821b extends from a left side edge of the main plate 81 of the second fixed base 8 along the up-down direction D2 toward the first fixed base 7 between the filter substrate 210 and the side plate 33 in the width direction D3.

[0070] An attachment plate 831a is provided at the front end of the first intervening member 821a. Similarly, an attachment plate 831b is provided at the front ends of the two first intervening members 821b. The rear surface of the main plate 71 of the first fixed base 7 is attached to the attachment plates 831a and 831b. Here, the attachment plates 831a and 831b are formed by curving the front sides of the first intervening members 821a and 821b outward. The "outward direction" here refers to the direction from the filter substrate 210 toward the side plate 33 in the width direction D3. In other words, the attachment plate 831a is formed by curving the front sides of the two first intervening members 821a toward the right. On the other hand, the attachment plate 831b is formed by curving the first intervening member 821b toward the left.

[0071] 9, the second intervening member 822 extends from the main plate 81 of the second fixed base 8 toward the first fixed base 7 between the filter substrate 210 and the converter substrate 220 in the up-down direction D2. Two mounting plates 832 are provided at the front end of the second intervening member 822. The rear surface of the main plate 71 of the first fixed base 7 is attached to the front surfaces of the two mounting plates 832. Here, the two mounting plates 832 are formed by curving the front side of the second intervening member 822 downward.

[0072] The two third intervening members 823a, 823b face each other in the left-right direction (width direction D3). As shown in Fig. 9, the third intervening member 823a has a first portion 8231a, a second portion 8232a, and a connecting portion 8233a.

[0073] The first portion 8231a extends from the right side edge of the main plate 81 of the second fixed base 8 along the up-down direction D2 toward the rear surface of the protruding portion 73a between the converter board 220 and the side plate 33 in the width direction D3.

[0074] An attachment plate 8331a is provided at the front end of the first portion 8231a. As shown in FIG. 10, the rear surface of the protrusion 73a is attached to the front surface of the attachment plate 8331a. Here, the attachment plate 8331a is formed by curving the front side of the first portion 8231a outward. The "outward direction" here refers to the direction from the converter board 220 toward the side plate 33 in the width direction D3. That is, as shown in FIG. 9, the attachment plate 8331a is formed by curving the front side of the first portion 8231a rightward.

[0075] The second portion 8232a extends from the right side edge of the main plate 81 of the second fixed base 8 along the vertical direction D2 between the converter board 220 and the side plate 33 in the width direction D3 toward the rear surface of the mounting plate 74c of the second extending portion 722a.

As shown in FIG. 10, the rear surface of the attachment plate 74c of the second extension portion 722a is attached to the front surface of the attachment plate 8332a. Here, the attachment plate 8332a is formed by curving the front side of the second portion 8232a outward. The "outward direction" here refers to the direction from the converter board 220 toward the side plate 33 in the width direction D3. That is, as shown in FIG. 9, the attachment plate 8332a is formed by curving the front side of the second portion 8232a to the right.

[0077] The first part 8231a is provided below the second part 8232a in the up-down direction D2. The front end of the first part 8231a is located rearward of the front end of the second part 8232a in the front-rear direction (opposing direction D1). In other words, the mounting plate 8331a is located rearward of the mounting plate 8332a in the front-rear direction. The connecting part 8233a connects the rear part of the first part 8231a and the rear part of the second part 8232a.

[0078] As shown in FIG. 9, like the third intervening member 823a, the third intervening member 823b has a first portion 8231b, a second portion 8232b, and a connecting portion 8233b.

[0079] The first portion 8231b extends from the left side edge of the main plate 81 of the second fixed base 8 along the up-down direction D2 toward the rear surface of the protruding portion 73b between the converter board 220 and the side plate 33 in the width direction D3.

[0080] An attachment plate 8331b is provided at the front end of the first portion 8231b. The rear surface of the protrusion 73b is attached to the front surface of the attachment plate 8331b. Here, the attachment plate 8331b is formed by curving the front side of the first portion 8231b outward. The "outward direction" here refers to the direction from the converter board 220 toward the side plate 33 in the width direction D3. In other words, the attachment plate 8331b is formed by curving the front side of the first portion 8231b leftward.

[0081] The second portion 8232b extends from the left side edge of the main plate 81 of the second fixed base 8 along the vertical direction D2 between the converter board 220 and the side plate 33 in the width direction D3 toward the rear surface of the mounting plate 74d of the second extension portion 722b.

[0082] An attachment plate 8332b is provided at the front end of the second portion 8232b. The rear surface of the attachment plate 74d of the second extension portion 722b is attached to the front surface of the attachment plate 8332b. Here, the attachment plate 8332b is formed by curving the front side of the second portion 8232b outward. The "outward direction" here refers to the direction from the converter board 220 toward the side plate 33 in the width direction D3. In other words, the attachment plate 8332b is formed by curving the front side of the second portion 8232b leftward.

[0083] The first part 8231b is provided below the second part 8232b in the up-down direction D2. The front end of the first part 8231b is located rearward of the front end of the second part 8232b in the front-rear direction (opposing direction D1). In other words, the mounting plate 8331b is located rearward of the mounting plate 8332b in the front-rear direction. The connecting part 8233b connects the rear part of the first part 8231b and the rear part of the second part 8232b.

[0084] As shown in FIG. 9 , the fourth intervening member 824 extends from the main plate 81 of the second fixed base 8 toward the first fixed base 7 above the converter board 220. The fourth intervening member 824 is formed in a generally inverted U shape when viewed from the front. A mounting plate 834 is provided at the front end of the upper part of the fourth intervening member 824. The rear surface of the main plate 71 of the first fixed base 7 is attached to the front surface of the mounting plate 834. Here, the mounting plate 834 is formed by curving the front side of the upper part of the fourth intervening member 824 downward.

[0085] (2-6) Inner lid The inner lid 96 prevents the power supply unit 2 from being exposed to rainwater, dust, or the like when the panel 4 is removed from the housing 3. The inner lid 96 is a rectangular plate member. The thickness direction of the inner lid 96 is along the facing direction D1.

[0086] The inner lid 96 is attached to the first fixed base 7. As shown in FIGS. 4 and 5, the inner lid 96 has a reinforcing plate 961a at its right edge and a reinforcing plate 961b at its left edge. The inner lid 96 also has a reinforcing plate 961c at its upper edge. The reinforcing plates 961a, 961b, and 961c are plate members. The right reinforcing plate 961a protrudes rightward from the right edge of the inner lid 96. The left reinforcing plate 961b protrudes leftward from the left edge of the inner lid 96. Similarly, the upper reinforcing plate 961c protrudes upward from the upper edge of the inner lid 96. The lower surface of the reinforcing plate 961a is attached to the upper surfaces of the mounting plates 74a and 74c of the first fixed base 7.

The lower surface of the reinforcing plate 961c is attached to the upper surface of the attachment plate 74e of the first fixed base 7.

[0087] 2 and 6, the inner lid 96 is housed in the housing 3. The inner lid 96 is disposed inside the housing 3 on the main board 71 side of the first fixed base 7. The second space S2 is a space sandwiched between the inner lid 96 and the main board 71 of the first fixed base 7 in the facing direction D1.

[0088] (2-7)Terminal block The communication terminal 5a and the mobile object terminal 5b are installed on the terminal block 97. The terminal block 97 is housed in the housing 3. As shown in FIG. 2, the terminal block 97 is disposed on the lower side inside the housing 3.

[0089] As shown in FIG. 4, the terminal block 97 has a main portion 971, a first connecting portion 972, and a second connecting portion 973. The main portion 971 is a rectangular plate member. As shown in FIG. 2, the first connecting portion 972 is a plate member that protrudes rearward from the rear end of the main portion 971. The first connecting portion 972 connects the main portion 971 to the main plate 81 of the second fixed base 8.

The second connecting portion 973 connects the main portion 971 to the lower end of the inner lid 96.

[0090] 2, the first space S1 is a space surrounded by the inner lid 96, the first fixed base 7, and the main portion 971 and first connecting portion 972 of the terminal base 97. On the other hand, the second space S2 is a space surrounded by the first fixed base 7, the second fixed base 8, and the main portion 971 and second connecting portion 973 of the terminal base 97.

[0091] The first connecting portion 972 is provided with an intake hole 974 for drawing air into the first space S1.

[0092] The communication terminal 5a is connected to a wiring that is electrically connected to an external device. An installer of the mobile object charging device 1 can connect the external device to the communication terminal 5a and perform settings of the power supply unit 2, etc., from the external device. The communication terminal 5a of this embodiment is provided to penetrate the second coupling part 973. Specifically, as shown in FIG. 8 , the communication terminal 5a of this embodiment is provided in the second coupling part 973 so that the side to which the first cable 6a that electrically connects the control board 230 and the communication terminal 5a is connected is located above the second coupling part 973, and the side to which the mobile object cable C1 is connected is located below the second coupling part 973.

[0093] A mobile object cable C1, which is inserted into a charging port of the mobile object B1, is connected to the mobile object terminal 5b. The mobile object charging device 1 can be easily electrically connected to the mobile object B1 via the mobile object terminal 5b. The mobile object terminal 5b of this embodiment is provided to penetrate the second coupling portion 973. Specifically, the mobile object terminal 5b of this embodiment is provided on the second coupling portion 973 so that the side to which the second cable 6b, which electrically connects the control board 230 and the mobile object terminal 5b, is connected is located above the second coupling portion 973, and the side to which the mobile object cable C1 is connected is located below the second coupling portion 973. In addition, a power line electrically connecting the mobile object terminal 5b to the filter board 210 is connected.

[0094] In this embodiment, the communication terminal 5a is arranged on the left side of the mobile object terminal 5b in the second connecting portion 973. In other words, the mobile object terminal 5b is arranged on the right side of the communication terminal 5a in the second connecting portion 973.

[0095] In addition, in this embodiment, an insertion groove 975 is provided at the right end of the second coupling part 973, through which the third cable 6c that electrically connects the control board 230 and the fan 5c is inserted. That is, the insertion groove 975 is provided in the second coupling part 973 on the right side of the movable body terminal 5b.

[0096] (2-8) Cable The three cables 6 electrically connect the control power supply board 240 to each of the three electronic components 5. Each of the three electronic components 5 is disposed below the control power supply board 240 inside the housing 3.

[0097] In this embodiment, the three cables 6 are a first cable 6a, a second cable 6b, and a third cable 6c, as shown in FIG.

[0098] The first cable 6a electrically connects the control board 230 and the communication terminal 5a. As a result, the control circuit 23 can control the converter circuit 22 based on the settings of the power supply unit 2, which are performed by an installer of the mobile object charging device 1 from an external device via the communication terminal 5a.

[0099] The second cable 6b electrically connects the control board 230 and the mobile object terminal 5b, which allows the control circuit 23 to obtain information on the status of the storage battery B12 and information on whether the mobile object charging device 1 and the mobile object B1 are electrically connected.

[0100] The third cable 6c electrically connects the control board 230 and the fan 5c, thereby enabling the control circuit 23 to control the operation of the fan 5c.

[0101] The wiring of the first cable 6a, the second cable 6b, and the third cable 6c will be described below with reference to Figures 8 and 10. When the first cable 6a, the second cable 6b, and the third cable 6c are not distinguished from each other, they will be collectively referred to as "cables 6." Figure 10 is a perspective view of the main parts of the mobile object charging device 1 with the panel 4, the inner lid 96, and the housing 3 removed.

[0102] The cable 6 is drawn out from the control board 230. Here, the cable 6 is drawn out from the right side of the control board 230, as shown in Fig. 8. The cable 6 drawn out from the control board 230 is routed downward along the up-down direction D2 between the control board 230 and the second extending portion 722a in the width direction D3.

[0103] 8 and 10, the portion of the cable 6 that overlaps with the upper end of the control power supply board 240 as viewed in the width direction D3 bends to the right and is routed on the upper surface of the protrusion 73a. That is, the portion of the cable 6 that overlaps with the upper end of the control power supply board 240 as viewed in the width direction D3 is routed between the protrusion 73a and the opening 31 in the facing direction D1. The "portion that overlaps with the upper end of the control power supply board 240 as viewed in the width direction D3" here refers to the portion that is at the same position as the upper end of the control power supply board 240 in the up-down direction D2. In other words, at least a portion of the cable 6 in this embodiment is routed between the protrusion 73a and the opening 31 in the facing direction D1. This configuration has the advantage of preventing the cable 6 from being pinched by the inner lid 96.

[0104] As shown in FIGS. 8 and 10 , the portion of the cable 6 that overlaps with the first extending portion 721a as viewed in the width direction D3 is routed between the first extending portion 721a and the side plate 33 in the width direction D3. More specifically, the portion of the cable 6 that overlaps with the first extending portion 721a as viewed in the width direction D3 is routed between the first extending portion 721a and the right-side side plate 33 in the width direction D3. The “portion that overlaps with the first extending portion 721a as viewed in the width direction D3” here refers to the same position on the cable 6 as the first extending portion 721a in the up-down direction D2. In other words, at least a portion of the cable 6 in this embodiment is routed between the first extending portion 721a and the side plate 33 in the width direction D3. This configuration has the effect of reducing the space required for routing the cable 6 in the second space S2. As a result, there is an advantage in that the device can be made even more compact.

[0105] In other words, the portion of the cable 6 that overlaps with the first extending portion 721a as viewed in the width direction D3 is routed along the outer surface of the first extending portion 721a in the width direction D3. The "outer surface of the first extending portion 721a" here refers to the surface of the first extending portion 721a on the side of the side panel 33. That is, in this embodiment, the portion of the cable 6 that overlaps with the first extending portion 721a as viewed in the width direction D3 is routed along the right surface of the first extending portion 721a in the width direction D3. In short, at least a portion of the cable 6 is routed along the outer surface of the first extending portion 721a in the width direction D3.

[0106] Furthermore, the portion overlapping with the first extending portion 721a when viewed from the width direction D3 is routed behind the mounting plate 64a in the front-rear direction (opposing direction D1). In other words, at least a portion of the cable 6 is routed behind the mounting plate 64a in the front-rear direction.

[0107] As shown in Figure 8, the first cable 6a pulled out from between the protrusion 73a and the opening 31 is wired to the front surface of the main board 71 of the first fixed base 7 and the front surface of the main part 971 of the terminal base 97, and is electrically connected to the communication terminal 5a.

[0108] Similarly, the second cable 6b pulled out from between the protrusion 73a and the opening 31 is wired to the front surface of the main board 71 of the first fixed base 7 and the front surface of the main part 971 of the terminal base 97, and is electrically connected to the mobile body terminal 5b.

[0109] The third cable 6c drawn out from between the protrusion 73a and the opening 31 is routed to the front surface of the main board 71 of the first fixed base 7 and the front surface of the main part 971 of the terminal block 97, and is inserted into the insertion groove 975 of the second coupling part 973. The third cable 6c inserted into the insertion groove 975 is routed to the front surface of the main part 971 of the terminal block 97 and the front surface of the main board 81 of the second fixed base 8. In this embodiment, the third cable 6c routed to the front surface of the main board 81 of the second fixed base 8 branches into two. One of the branched third cables 6c passes through the left insertion hole 84 and is electrically connected to the left fan 5c, and the other passes through the right insertion hole 84 and is electrically connected to the right fan 5c.

[0110] (2-9) Bass In this embodiment, the base 91 is placed on an installation surface X1, and the housing 3 is placed on the base 91, as shown in FIG.

[0111] The base 91 is a hollow box-like structure with open top and bottom surfaces. The base 91 is made of, for example, metal. The base 91 may be painted with paint or the like.

[0112] As shown in FIGS. 4 and 5, the base 91 includes a base main body 911 and a base panel 912.

[0113] The base main body 911 includes a right plate 9111, a left plate 9112, and a rear plate 9113, and is formed in a substantially U-shape when viewed from above. Each of the right plate 9111, the left plate 9112, and the rear plate 9113 is a rectangular plate.

[0114] An insertion recess 913 is formed at the lower end of the rear plate 9113. The insertion recess 913 has a first portion extending upward from the center in the left-right direction of the lower edge of the rear plate 9113, and a second portion extending left and right from the upper end of the first portion, and is formed in a generally T-shape when viewed from the front. The mobile body cable C1 drawn out from the lower plate 34 of the housing 3 is passed through the insertion recess 913 of the base 91 and routed to the rear side of the base 91, i.e., the rear side of the housing 3.

[0115] The base panel 912 is a rectangular plate and is attached to the base body 911 with screws so as to close the opening on the front side of the base body 911.

[0116] (2-10) Resin cover The resin cover 92 is a hollow box-like shape with openings on the bottom, front, and rear. The resin cover 92 is attached to the housing 3 with screws, for example, so as to cover the top plate 35 (see FIG. 2) of the housing 3.

[0117] As shown in Fig. 4, an operation display panel 93 is disposed in the opening on the front surface of the resin cover 92. The operation display panel 93 has a plurality of (here, five) operation buttons 931 and a plurality of (here, six) indicator lights 932 on its front surface. The plurality of operation buttons 931 may include a charge start button that outputs a charge command to instruct the start of charging, a charge stop button that outputs a stop command to instruct the stop of charging, etc. The plurality of indicator lights 932 indicate a plurality of operating states of the mobile object charging device 1 (for example, a charging state, a charging completion state, an abnormality state, etc.) by, for example, lighting up or blinking.

[0118] 2, a duct 94 is disposed in the opening on the rear surface of the resin cover 92. The duct 94 dissipates heat generated by the power supply unit 2 housed in the housing 3 to the outside of the housing 3.

[0119] (2-11) Cable holder When the mobile object cable C1 is not connected to the mobile object B1, the cable holder 951 detachably holds the mobile object cable C1 to the housing 3, as shown in FIG. 1. More specifically, the cable holder 951 detachably holds the handle portion C11 of the mobile object cable C1 to the housing 3, as shown in FIG. 1. In this embodiment, the cable holder 951 is attached to the right side surface of the housing 3. Note that the cable holder 951 may also be attached to the left side surface of the housing 3.

[0120] As shown in FIG. 8, the cable holder 951 has a tubular structure 952 into which the tip of the handle portion C11 of the mobile object cable C1 is inserted when the mobile object cable C1 is not connected to the mobile object B1.

[0121] (2-12) Cable guide The mobile object cable C1 is hooked onto the cable guide 953. The cable guide 953 of this embodiment is capable of hooking the mobile object cable C1 in a wound state, as shown in Fig. 1. The cable guide 953 is formed in a generally inverted U shape when viewed from the side.

[0122] The cable guide 953 has a protruding plate 954. The protruding plate 954 protrudes upward from the right side edge of the cable guide 953. A space in which the movable body cable C1 is hooked is formed so as to be surrounded by the cable guide 953, the protruding plate 954, and the side surface (right side surface) of the housing 3. The protruding plate 954 prevents the hooked movable body cable C1 from falling off the cable guide 953.

[0123] (3) Variations Modifications of the above-described embodiment are listed below. The following modifications may be implemented in appropriate combination.

[0124] The mobile object charging device 1 of the above-described embodiment supplies power to charge the storage battery B12 of the mobile object B1. However, the mobile object charging device 1 of the embodiment may also be capable of outputting power discharged from the storage battery B12 of the mobile object B1 to an external electric circuit. That is, the power supply unit 2 of the mobile object charging device 1 is further configured to receive power discharged from the storage battery B12 of the mobile object B1 and output the received power to an external electric circuit. In short, the mobile object charging device 1 may be a charging / discharging device capable of both charging and discharging the storage battery B12 of the mobile object B1.

[0125] Although at least a portion of the cable 6 in the above-described embodiment is routed between the first extending portion 721a and the side plate 33 in the width direction D3, it may also be routed between the first extending portion 721b and the side plate 33. In other words, at least a portion of the cable 6 may be routed along the outer surface of the first extending portion 721b in the width direction D3. The "outer surface of the first extending portion 721b" here refers to the surface of the first extending portion 721b facing the side plate 33, that is, the left surface of the first extending portion 721b. In this case, the portion of the cable 6 that overlaps with the upper end of the control power supply board 240 when viewed from the width direction D3 is routed between the protruding portion 73b and the opening 31 in the opposing direction D1.

[0126] Furthermore, although at least a portion of the cable 6 in the above-described embodiment is routed behind the mounting plate 64a in the front-rear direction, it may be routed behind the mounting plate 64b.

[0127] Furthermore, at least a portion of the cable 6 in the above-described embodiment is routed between the first extending portion 721a and the side plate 33 in the width direction D3. However, at least a portion of the cable 6 may be routed to the rear side of the main board 71 of the first fixed base 7 and routed along the rear surface of the main board 71. More specifically, the portion of the cable 6 that overlaps with the control power supply board 240 as seen from the width direction D3 may be routed to the rear side of the main board 71 of the first fixed base 7 and routed along the rear surface of the main board 71. In other words, at least a portion of the cable 6 may be routed in the first space S1. Even with this configuration, there is an advantage that the mobile body charging device 1 can be made more compact.

[0128] Furthermore, the cable 6 in the above-described embodiment is drawn out from the right side of the control board 230 and wired downward along the up-down direction D2 between the control board 230 and the second extending portion 722a in the width direction D3. However, the cable 6 may be drawn out from the left side of the control board 230 and wired downward along the up-down direction D2 between the control board 230 and the second extending portion 722b in the width direction D3.

[0129] Furthermore, the cable 6 may be drawn out from the upper or lower side of the control board 230. In other words, the position where the cable 6 is drawn out from the control board 230 is not limited.

[0130] The control circuit 23 in the above-described embodiment controls the converter circuit 22, but may also control the first filter circuit 21a and the second filter circuit 21b. For example, the control circuit 23 may control the first filter circuit 21a and the second filter circuit 21b based on information about the storage battery B12 obtained from the mobile object B1 via the mobile object cable C1 so that the converter circuit 22 extracts frequency components suitable for the storage battery B12 of the mobile object B1. As described above, it is sufficient for the control circuit 23 to control at least the converter circuit 22.

[0131] The mobile body charging device 1 in the above-described embodiment includes three electronic components 5, but may include one or two electronic components 5, or may include four or more electronic components 5. In short, it is sufficient for the mobile body charging device 1 to include at least one electronic component 5.

[0132] Furthermore, the mobile object charging device 1 of the above-described embodiment includes three electronic components 5: a communication terminal 5a, a mobile object terminal 5b, and a fan 5c. However, the mobile object charging device 1 may include at least one of the communication terminal 5a, the mobile object terminal 5b, and the fan 5c as at least one electronic component 5. That is, the at least one electronic component 5 may include the communication terminal 5a. Similarly, the at least one electronic component 5 may include the mobile object terminal 5b or the fan 5c.

[0133] The housing 3 in the above-described embodiment includes the housing main body 30, the lower plate 34, and the upper plate 35, but may not include the lower plate 34 and the upper plate 35. In other words, the interior of the housing 3 may be connected to the interiors of the base 91 and the resin cover 92.

[0134] Although the mobile body charging device 1 of the above-described embodiment includes the base 91, it does not necessarily have to include the base 91. In this case, the housing 3 is placed directly on the placement surface X1.
