[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 housing 3, a front panel 4, a base 5, and a base panel 6. The housing 3 houses the power supply unit 2. The front panel 4 covers the power supply unit 2 housed in the housing 3. The housing 3 is attached to the base 5. The base panel 6 is attached to the base 5.

[0012] 2, the front panel 4 has a first end 41 and a second end 42 as a pair of ends facing each other along an arrangement direction D1 in which the housing 3 and the base 5 are arranged. The first end 41 is fixed to the housing 3 by a fastening portion 94. At least a portion of the second end 42 is pressed toward the base 5 by an edge portion 61 of the base panel 6.

[0013] For example, when a force is applied to the front panel 4 from inside the housing 3 toward the outside due to an increase in internal pressure of the housing 3, the front panel 4 bends outward. Because the second end 42 is not fixed to the housing 3, the bending of the front panel 4 displaces the second end 42 toward the first end 41 along the arrangement direction D1 while maintaining a state in which the second end 42 is pressed toward the base 5 by the edge portion 61 of the base panel 6. As a result, an effect is achieved in which load on the fastening portion 94 can be suppressed. Therefore, the mobile body charging device 1 of this embodiment has the advantage of being able to suppress detachment of the front panel 4.

[0014] (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 7.

[0029] (2-3) Power supply section The power supply unit 2 is housed in a housing 3. The power supply unit 2 includes a plurality of circuit boards and a plurality of circuit components mounted on the boards. The plurality of circuit boards are arranged inside the housing 3 so as to face the rear panel 32 of the housing main body 30. The housing 3 also houses a heat sink for dissipating heat generated by the power supply unit 2.

[0030] 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.

[0031] The power supply unit 2 is configured to be electrically connectable to the mobile body B1 via a mobile body cable C1. The power supply unit 2 is connected to one end of the mobile body cable C1, and the other end of the mobile body cable C1 is configured to be electrically connectable to the mobile body B1. When the mobile body cable C1 is connected to the mobile body B1, the power supply unit 2 is electrically connected to the mobile body B1 via the mobile body cable C1. This enables the power supply unit 2 to supply power to the storage battery B12 of the mobile body B1 via the mobile body cable C1 and to communicate with the mobile body B1.

[0032] As shown in FIG. 3, the power supply unit 2 includes an input unit 21, a current control unit 22, a relay 23, a protection circuit 24, and a vehicle communication unit 25.

[0033] The input unit 21 receives a charge command and a stop command from the operation display panel 91. Note that the input unit 21 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).

[0034] The energization control unit 22 controls energization from the mobile object charging device 1 to the mobile object B1. Here, the energization control unit 22 controls energization to the mobile object B1 by driving the relay 23 in accordance with the charge command and stop command received by the input unit 21. Basically, when the input unit 21 receives a charge command, the energization control unit 22 turns on (conductive state) the relay 23 to conduct an electric 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 21 receives a stop command, the energization control unit 22 turns off (interrupted state) the relay 23 to interrupt the electric path from the power supply unit 2 to the mobile object B1, thereby stopping the charging of the storage battery B12.

[0035] 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 21 receives a charge command, the current control unit 22 does not turn on (conductive state) the relay 23 and cuts off the electrical path from the power supply unit 2 to the mobile object B1.

[0036] The energization control unit 22 is mainly composed of a computer system including a memory and a processor. That is, the functions of the energization control unit 22 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.

[0037] The relay 23 is provided in the power supply path to the storage battery B12. Specifically, the relay 23 is provided between the power input side connection terminal of the power supply unit 2 and the connection terminal with the mobile object cable C1. As a result, when the relay 23 is on (conductive state), power can be supplied from the power source (commercial AC power source, etc.) to the storage battery B12 of the mobile object B1. On the other hand, when the relay 23 is off (cut-off state), power is not supplied from the power source to the storage battery B12 of the mobile object B1. The relay 23 may be any type that can be controlled by the current control unit 22, and may be a mechanical relay with mechanical contacts or a semiconductor relay without mechanical contacts.

[0038] The protection circuit 24 is a circuit that protects the power supply unit 2 and the mobile object B1 by turning off the relay 23 when an abnormality such as a power leak or an overcurrent is detected. The protection circuit 24 may include, in addition to the relay 23, an element that cuts off the supply of power to the mobile object B1.

[0039] The vehicle communication unit 25 communicates with the mobile body B1 directly or indirectly via a network, a repeater, or the like. As a communication method between the vehicle communication unit 25 and the mobile body B1, an appropriate communication method such as wireless communication or wired communication is adopted. As an example, in this embodiment, the vehicle communication unit 25 performs communication to confirm the connection between the power supply unit 2 and the mobile body B1 and to confirm the status of the mobile body B1, etc., using at least a CPLT (Control Pilot) signal.

[0040] (2-4) Bass 1, in this embodiment, the base 5 is placed on an installation surface S1, and the housing 3 is attached on the base 5. That is, in this embodiment, the arrangement direction D1 in which the housing 3 and the base 5 are arranged is the up-down direction.

[0041] The base 5 is a hollow box-like structure with open top and bottom surfaces. The base 5 is made of, for example, metal. The base 5 may be painted with paint or the like.

[0042] 4, the base 5 includes a right plate 51, a left plate 52, and a rear plate 53, and is formed in a generally U-shape when viewed from above. Each of the right plate 51, the left plate 52, and the rear plate 53 has a rectangular plate shape.

[0043] The base 5 further includes a reinforcing plate 541 extending from the front edge of the right plate 51 in a direction approaching the left plate 52. That is, the reinforcing plate 541 extends leftward from the front edge of the right plate 51. The reinforcing plate 541 is provided on the front edge of the right plate 51 across the vertical direction.

[0044] Similarly, the base 5 further includes a reinforcing plate 542 extending from the front edge of the left plate 52 in a direction approaching the right plate 51. That is, the reinforcing plate 542 extends rightward from the front edge of the left plate 52. The reinforcing plate 542 is provided on the front edge of the left plate 52 across the vertical direction.

[0045] An attachment plate 551 is provided on the upper left edge of the reinforcing plate 541. Similarly, an attachment plate 552 is provided on the upper right edge of the reinforcing plate 542. The attachment plates 551 and 552 are L-shaped plate members when viewed from above. A base panel 6 is attached to the attachment plates 551 and 552. As shown in FIGS. 4 and 6, a fixing portion 56 to which a corresponding one of the two second fastening portions 95 is fixed is provided on the upper portion of each of the attachment plates 551 and 552. That is, the fixing portion 56 provided on the attachment plate 551 fixes one of the two second fastening portions 95, and the fixing portion 56 provided on the attachment plate 552 fixes the other of the two second fastening portions 95. As shown in FIG. 6, the fixing portion 56 is cylindrical. A spiral thread groove (not shown) that fits onto the screw shaft of the second fastening portion 95 is formed on the inner peripheral surface of the fixing portion 56.

[0046] (2-5) Front panel The front panel 4 opens and closes the opening 31 of the housing 3. More specifically, as shown in FIGS. 2 and 5, the front panel 4 is detachably attached to the front side of the housing 3 so as to cover the opening 31. In other words, the front panel 4 is detachably attached to the front side of the housing 3 so as to cover the power supply unit 2 housed in the housing 3. In this embodiment, the front panel 4 is a long plate member. The arrangement direction D1 is the longitudinal direction of the front panel 4. This configuration has the advantage that when a force is applied to the front panel 4 from inside the housing 3 in the forward direction, the front panel 4 is likely to bend forward. The front panel 4 is made of, for example, metal.

[0047] The front panel 4 includes a main board 40 that covers the power supply unit 2 housed in the housing 3. The main board 40 is a rectangular plate member. When the front panel 4 is attached to the housing 3, the main board 40 is supported by support plates 331, 341, 351, and 361 with a sealing member 93 sandwiched therebetween, as shown in FIGS. 5 to 7. This configuration has the effect of improving the airtightness of the interior of the housing 3. As shown in FIG. 4, the sealing member 93 is a rectangular frame-shaped plate member. The sealing member 93 is preferably a waterproof member, such as a packing member. For example, the sealing member 93 is made of a rubber material.

[0048] 2, the front panel 4 has a pair of ends, a first end 41 and a second end 42, that face each other along the arrangement direction D1 (vertical direction). In this embodiment, the first end 41 is the upper end of the pair of ends that face each other along the vertical direction. On the other hand, the second end 42 is the lower end of the pair of ends that face each other along the vertical direction.

[0049] 4, the first end 41 is fixed to the upper part of the housing 3 by two first fastening portions 94. The method for fixing the first end 41 of the front panel 4 will be described in more detail below.

[0050] As shown in FIGS. 4 and 7 , the first end portion 41 has an extending portion 411 and two protruding plates 412. The extending portion 411 and the two protruding plates 412 are rectangular plate-shaped. As shown in FIG. 7 , the extending portion 411 extends from the main plate 40 along a transverse direction D2 intersecting with the main plate 40. In this embodiment, the "transverse direction D2" is the front-rear direction. That is, in this embodiment, the extending portion 411 extends rearward from the upper edge of the main plate 40. The two protruding plates 412 protrude from the tip of the extending portion 411 along the arrangement direction D1. In this embodiment, the two protruding plates 412 protrude upward from the rear end of the extending portion 411. As shown in FIG. 4 , the two protruding plates 412 are provided at the rear end of the extending portion 411 in positions facing each other in the left-right direction.

[0051] Each of the two protruding plates 412 has an insertion hole 413 through which a corresponding one of the two first fastening portions 94 is inserted. That is, one of the two first fastening portions 94 is inserted into the insertion hole 413 provided in the right-side protruding plate 412, and the other of the two first fastening portions 94 is inserted into the insertion hole 413 provided in the left-side protruding plate 412. The two first fastening portions 94 are, for example, screws. As shown in FIG. 7 , each of the two first fastening portions 94 is inserted into the corresponding insertion hole 413 of the protruding plate 412 of the front panel 4 and fixed to the corresponding fixing portion 363 of the support plate 361 of the housing 3, thereby fixing the first end portion 41 of the front panel 4 to the upper part of the housing 3.

[0052] 6, the second end portion 42 has a first portion 421, a second portion 422, and a third portion 423. The first portion 421, the second portion 422, and the third portion 423 are rectangular plate-shaped. The first portion 421, the second portion 422, and the third portion 423 are provided at the lower end of the main board 40 across the left-right direction.

[0053] The first portion 421 extends from the main plate 40 along the transverse direction D2 (front-rear direction). In this embodiment, the first portion 421 extends rearward from the lower end of the main plate 40. The second portion 422 extends from the front end of the first portion 421 along the arrangement direction D1 (up-down direction). In this embodiment, the second portion 422 extends downward from the rear end of the first portion 421. The third portion 423 extends from the front end of the second portion 422 along the transverse direction D2. In this embodiment, the third portion 423 extends frontward from the lower end of the second portion. The dimension of the third portion 423 in the front-rear direction is smaller than the dimension of the first portion 421 in the front-rear direction. The shape of the first portion 421, the second portion 422, and the third portion 423 combined together is hook-shaped in side view.

[0054] When the front panel 4 is viewed from the arrangement direction D1, the third portion 423 overlaps at least a portion of the first portion 421. More specifically, when the front panel 4 is viewed from the arrangement direction D1, the third portion 423 overlaps the rear portion of the first portion 421. In other words, the first portion 421 includes the third portion 423 within the projection plane in the arrangement direction D1.

[0055] (2-6) Base panel The base panel 6 is a plate member. The base panel 6 has a rectangular shape in a plan view. The base panel 6 is attached to the base 5 so as to close the opening on the front side of the base 5.

[0056] As shown in FIG. 4 , the base panel 6 has two insertion holes 63 through which corresponding ones of the two second fastening portions 95 are inserted. The two insertion holes 63 are provided on the upper side of the base panel 6 at positions facing each other in the left-right direction. That is, one of the two second fastening portions 95 is inserted into the right-side insertion hole 63, and one of the two second fastening portions 95 is inserted into the left-side insertion hole 63. Each of the two second fastening portions 95 is inserted into the corresponding insertion hole 63 of the base panel 6 and fixed to the corresponding fixing portions 56 of the mounting plates 551 and 552 of the base 5, thereby attaching the base panel 6 to the mounting plates 551 and 552 of the base 5. The two second fastening portions 95 are, for example, screws or the like.

[0057] As shown in FIG. 6 , the edge 61 of the base panel 6 has a curved portion 62. In the present disclosure, the "edge 61 of the base panel 6" refers to the upper edge of the base panel 6. The curved portion 62 is provided at the upper end of the base panel 6 across the left-right direction. The curved portion 62 is composed of a first extending portion 621 and a second extending portion 622. The first extending portion 621 extends rearward from the upper end of the base panel 6. The second extending portion 622 extends downward from the rear end of the first extending portion 621. The curved portion 62 is L-shaped in a side view.

[0058] The front-rear dimension of the first extending portion 621 is slightly smaller than or approximately the same as the front-rear dimension of the first portion 421. The up-down dimension of the second extending portion 622 is smaller than the up-down dimension of the second portion 422.

[0059] When the base panel 6 is attached to the base 5, the curved portion 62 is located between the first portion 421 and the third portion 423 of the front panel 4 in the up-down direction. That is, when the base panel 6 is attached to the base 5, the edge portion 61 of the base panel 6 is located between the first portion 421 and the third portion 423. This configuration has the effect of causing the upper surface 4231 of the third portion 423 to catch on the lower end 6222 of the second extending portion 622 when the second end portion 42 of the front panel 4 is displaced upward. This has the advantage of further preventing the front panel 4 from coming off the housing when the second end portion 42 of the front panel 4 is displaced upward.

[0060] When the base panel 6 is attached to the base 5, at least a portion of the second end 42 is pressed toward the base 5 by the edge 61 of the base panel 6. In the present embodiment, when the base panel 6 is attached to the base 5, the second portion 422 of the second end 42 is pressed toward the base 5 by the edge 61 of the base panel 6. More specifically, when the base panel 6 is attached to the base 5, the rear surface 6221 of the second extension portion 622 at the edge 61 presses the front surface 4221 of the second portion 422 at the second end 42 of the front panel 4 toward the base 5. Here, "pressing toward the base 5" means pressing toward the base along the front-to-rear direction, that is, pressing in the rearward direction.

[0061] In this embodiment, the vertical dimension of the second extending portion 622 is smaller than the vertical dimension of the second portion 422. Therefore, when the second portion 422 is pressed by the edge portion 61 of the base panel 6, a gap G1 is provided between the third portion 423 and the edge portion 61 of the base panel 6. More specifically, as shown in FIG. 6 , when the second portion 422 is pressed by the edge portion 61 of the base panel 6, a gap G1 is provided between the upper surface 4231 of the third portion 423 and the lower end 6222 of the second extending portion 622. This configuration has the advantage that the second end 42 of the front panel 4 can be displaced upward until the upper surface 4231 of the third portion 423 contacts the lower end 6222 of the second extending portion 622, while maintaining the state in which the second portion 422 is pressed by the second extending portion 622 of the base panel 6. In other words, the second end 42 of the front panel 4 has the advantage that it can be displaced upward until the gap G1 (see Figure 6) disappears, while maintaining the state in which the second portion 422 is pressed against the second extension portion 622 of the base panel 6.

[0062] A buffer member 8 is disposed between the front panel 4 and the base panel 6. As shown in FIG. 6 , the buffer member 8 of this embodiment is disposed between the front surface 4221 of the second portion 422 at the second end 42 of the front panel 4 and the rear surface 6221 of the second extension portion 622 of the base panel 6. That is, the rear surface 6221 of the second extension portion 622 presses the front surface 4221 of the second portion 422 toward the base 5 via the buffer member 8. This configuration can prevent direct contact between the front panel 4 and the base panel 6. This has the advantage of preventing wear on the front panel 4 and the base panel 6 due to vibrations and the like.

[0063] (2-7) Top cover The top cover 7 is a hollow box-like structure with an open bottom. Openings are formed in the center of the left-right direction on both the front and rear surfaces of the top cover 7. The top cover 7 is attached to the housing 3 with screws, for example, so as to cover the top plate 36 (see FIG. 2) of the housing 3.

[0064] As shown in FIG. 7 , when attached to the housing 3, the top cover 7 covers the two first fastening portions 94. More specifically, the top cover 7 is attached to the housing 3 so that the front surface of the top cover 7 covers the two first fastening portions 94 when viewed from the front. In other words, the top cover 7 is attached to the housing 3 so that the front surface of the top cover 7 includes the two first fastening portions 94 when projected in the front-to-rear direction. This configuration has the effect of making the two first fastening portions 94 less visible from outside the mobile body charging device 1. As a result, there is an advantage that the design of the mobile body charging device 1 is improved. There is also an advantage that intentional removal of the front panel 4 can be prevented.

[0065] As shown in Fig. 4, an operation display panel 91 is disposed in the opening on the front surface of the top cover 7. The operation display panel 91 has a plurality of (here, five) operation buttons 911 and a plurality of (here, six) indicator lights 912 on its front surface. The plurality of operation buttons 911 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 912 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.

[0066] 2, a duct 92 is disposed in the opening on the rear surface of the top cover 7. The duct 92 dissipates heat generated by the power supply unit 2 housed in the housing 3 to the outside of the housing 3.

[0067] (3) Advantages In the mobile body charging device 1 of this embodiment, the second end 42 (see FIG. 6) of the front panel 4 can be displaced upward until the third portion 423 comes into contact with the second extension portion 622, while maintaining a state in which the second portion 422 is pressed toward the base 5 by the second extension portion 622 of the base panel 6. In other words, the second end 42 of the front panel 4 can be displaced upward until the gap G1 (see FIG. 6) disappears, while maintaining a state in which the second portion 422 is pressed by the second extension portion 622 of the base panel 6.

[0068] For example, when a force is applied to the front panel 4 from inside the housing 3 in a forward direction due to an increase in internal pressure of the housing 3, the front panel 4 bends forward. Because the second end 42 is not fixed to the housing 3, the bending of the front panel 4 causes the second end 42 to be displaced upward while maintaining a state in which it is pressed toward the base 5 by the second extension portion 622 of the base panel 6. As a result, an effect is achieved in which load on the first fastening portion 94 can be suppressed. Therefore, the mobile body charging device 1 of this embodiment has the advantage of being able to suppress the front panel 4 from coming off the housing 3.

[0069] (4) Variations Modifications of the above-described embodiment are listed below. The following modifications may be implemented in appropriate combination.

[0070] 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.

[0071] Although the edge 61 of the base panel 6 in the above-described embodiment has the first extension 621 and the second extension 622 as the curved portion 62, it may have only the first extension 621. In other words, the edge 61 of the base panel 6 does not have to have the second extension 622. When the edge 61 of the base panel 6 has only the first extension 621, the rear end of the first extension 621 presses the front surface 4221 of the second part 422 at the second end 42 of the front panel 4 toward the base 5.

[0072] In the mobile body charging device 1 of the above-described embodiment, when the second portion 422 is pressed by the edge portion 61 of the base panel 6, a gap G1 is provided between the upper surface 4231 of the third portion 423 of the front panel 4 and the lower end 6222 of the second extending portion 622 of the base panel 6. However, it is sufficient that the gap G1 is provided between the front panel 4 and the base panel 6 when at least a part of the second end portion 42 is pressed by the edge portion 61 of the base panel 6. For example, if the edge portion 61 of the base panel 6 has only the first extending portion 621, a gap may be provided between the third portion 423 of the front panel 4 and the first extending portion 621 of the base panel 6 when the second portion 422 is pressed by the edge portion 61 of the base panel 6.

[0073] In the above-described embodiment, the second end 42 of the front panel 4 includes the first portion 421, the second portion 422, and the third portion 423. However, the second end 42 of the front panel 4 may include only the first portion 421 and the second portion 422. In this case, the combined shape of the first portion 421 and the second portion 422 forms an inverted L shape in a side view. With this configuration, when a force is applied to the front panel 4 from inside the housing 3 in the forward direction, the second portion 422 of the second end 42 of the front panel 4 comes out from between the base 5 and the base panel 6, thereby reducing the load on the two first fastening portions 94. This has the advantage of preventing the front panel 4 from coming out of the housing.
