In FIGS. 1 and 2, an entrance opening portion 22 is formed on the side surface 15, and the body 11 includes a door 23 and a door 24 configured to open and close the entrance opening portion 22. Note that, in examples illustrated in FIGS. 1 and 2, a driver seat is placed not on a side-surface-15 side but on a side-surface-16 side, and the driver seat is provided with an operating portion such as a steering wheel for operating the vehicle 10.

The side surface 15 is provided with a fuel filling portion 20 and a charging portion 21. The fuel filling portion 20 is provided on the peripheral surface 14, and is placed on a rear side relative to the entrance opening portion 22. The charging portion 21 is provided on the side surface 16, and is placed on the rear side relative to the entrance opening portion 22. Note that a mounting position of the charging portion 21 is not limited to the side surface 15. For example, the charging portion 21 can be provided on the front surface, the back surface, the top surface, or the like of the vehicle 10. Note that the top surface may be an engine roof or the like.

The fuel filling portion 20 is provided with a nozzle insertion portion 20a into which a nozzle portion of a fuel filling nozzle provided outside is inserted, and a cover portion 20b provided on the body 11. When the cover portion 20b is opened, an opening of the nozzle insertion portion 20a is exposed outside, so that the nozzle of the fuel filling nozzle can be inserted into the nozzle insertion portion 20a.

The nozzle insertion portion 20a is connected to the fuel tank FT, and a fuel supplied from the nozzle insertion portion 20a is supplied to the fuel tank FT. Note that, in a vehicle including an internal combustion engine, the fuel to be supplied may be gasoline, LP gas (Liquefied petroleum gas), or the like. Further, in a vehicle including a fuel cell, the fuel to be supplied may be liquid hydrogen, ethanol, or the like.

The charging portion 21 includes a charging connector 21a to which a charging plug 93 provided outside is to be attached, and a cover portion 21b provided on the body 11. When the cover portion 21b is opened, the charging connector 21a is exposed outside, so that the charging plug 93 is attachable to the charging connector 21a.

Electric power supplied from the charging connector 21a is supplied to the battery B via the charging connector 21a, a transducer, or the like.

In FIG. 2, an entrance opening portion 25 is formed on the side surface 16, and the body 11 is provided with a door 26 and a door 27 configured to open and close the entrance opening portion 25.

FIG. 3 is a block diagram illustrating the vehicle 10. The vehicle 10 includes an engine 1, motor generators MG1, MG2, a power distribution mechanism 2, the battery B, a capacitor C, a reactor L, a converter 4, an inverter 5 and an inverter 6, a vehicle ECU (Electronic Control Unit) 7, a switching element 8 such as a relay, a transducer 9, and the charging portion 21.

The power distribution mechanism 2 is connected to the engine 1 and the motor generators MG1, MG2, so as to distribute power to them. For example, a planet gear mechanism having three rotating shafts, i.e., a sun gear, a planetary carrier, and a ring gear, is used as the power distribution mechanism 2. The three rotating shafts are connected to respective rotating shafts of the engine 1 and the motor generators MG1, MG2. For example, a rotor of the motor generator MG1 is hollowed, so that a crank shaft of the engine 1 is inserted into a center thereof. Thus, the engine 1 and the motor generators MG1, MG2 are mechanically connected to the power distribution mechanism 2.

Note that the rotating shaft of the motor generator MG2 is connected to front wheels 3, which are driving wheels, via a reducing gear and a differential gear (not shown). The reduction gear to the rotating shaft of the motor generator MG2 may be further incorporated inside the power distribution mechanism 2.

The motor generator MG1 works as a generator driven by the engine 1, and is incorporated in the vehicle 10 as a member working as an electric motor that can start the engine 1. The motor generator MG2 is incorporated in the vehicle 10 as an electric motor configured to drive the front wheels 3, which are driving wheels of the vehicle 10.

The motor generators MG1, MG2 are three-phase alternating synchronous motors, for example. The motor generators MG1, MG2 each include, as a stator coil, a three-phase coil including a U-phase coil, a V-phase coil, and a W-phase coil.

The motor generator MG1 generates a three-phase alternating voltage by use of an engine output, and outputs the three-phase alternating voltage thus generated to the inverter 5. The motor generator MG1 generates a driving force by a three-phase alternating voltage received from the inverter 5, so as to start the engine 1.

The motor generator MG2 generates a driving torque of the vehicle by a three-phase alternating voltage received from the inverter 6. At the time of regenerative brake of the vehicle, the motor generator MG2 generates a three-phase alternating voltage and outputs it to the inverter 6.

The switching element 8 is placed between the charging portion 21 and the transducer 9. The switching element 8 connects the charging portion 21 to the transducer 9, and disconnects the charging portion 21 from the transducer 9. The transducer 9 is controlled to be driven according to a control signal CNTL2 from the vehicle ECU7. The switching element 8 is switched between ON and OFF according to the control signal CNTL2 from the vehicle ECU7.

When the charging plug 93 is connected to the charging connector 21a of the charging portion 21 to charge the battery B, the vehicle ECU 7 turns on the switching element 8 to connect the charging portion 21 to the transducer 9. Then, the vehicle ECU 7 drives the transducer 9 to convert an alternating-current power supplied from an external power supply 91 into a direct-current power.

FIG. 4 is a side view illustrating a power extraction device 30. The power extraction device 30 is a device connected to the charging portion 21 illustrated in FIG. 2 to extract electric power accumulated in the battery B. An electric plug of a device such as rice cooker is connectable to the power extraction device 30, and an electric apparatus such as the rice cooker can be driven by electric power from the battery B.

In FIG. 4, the power extraction device 30 includes a body portion 33 formed in a column shape and a body portion 34 connected to the body portion 33. The body portion 33 includes: a connecting portion 31 provided in one end of the body portion 33 and connected to the charging portion 21 of the vehicle 10; a claw portion 35 hooked onto a recessed portion formed in the charging portion 21; and a switch 36 configured to disengage an engaged state between the claw portion 35 and the charging portion 21.

The connecting portion 31 includes: a terminal portion 37 connected to a terminal portion provided in the charging portion 21; and a tubular portion 38 fitted to an annular groove provided around the charging portion 21.

One end of the body portion 34 is connected to the other end of the body portion 33. The body portion 34 includes a connecting portion 32 provided in the other end of the body portion 34 and configured such that an electric plug of an external electric apparatus is connected thereto.

The connecting portion 32 includes: an end surface 39 formed in an end of the body portion 34; a connection surface 40 formed on the end surface 39 so that an electric plug is connected thereto; a protruding portion 41 provided above the connection surface 40; a cover 42 rotatably supported by a part at a position lower than the connection surface 40; a seal 43; and a loop wall portion 44.

A projection region R formed by projecting the connection surface 40 in a direction perpendicular to the connection surface 40 from a position away from the connection surface 40 passes through that end of the body portion 33 at which the connecting portion 31 is provided.

At least part of the connection surface 40 and at least part of the connecting portion 31 are formed so as to overlap each other horizontally in a state where the power extraction device 30 is connected to the charging portion 21.

A terminal hole into which a terminal of an electric plug to be connected is inserted is formed on the connection surface 40. Here, in a state where the power extraction device 30 is connected to the charging portion 21 of the vehicle 10, a virtual plane extending along the connection surface 40 is taken as a virtual plane 45.

In a state where the power extraction device 30 is connected to the charging portion 21, a straight line passing through the connection surface 40 and perpendicular to the virtual plane 45 is taken as a virtual straight line 46. In a state where the power extraction device 30 is connected to the charging portion 21, a virtual straight line passing through the connection surface 40 and extending horizontally is taken as a virtual straight line 47. As the virtual straight line 46 goes away from the connection surface 40, the virtual straight line 46 extends toward a downward direction relative to the virtual straight line 47. Thus, the connection surface 40 is placed in an inclined manner. As described above, the virtual straight line 47 is a virtual line extending horizontally, and a virtual line extending horizontally regardless of a connection posture of the power extraction device 30.

For example, in a case where the power extraction device 30 is used outdoors in the rain, since the connection surface 40 is placed in an inclined manner as described above, it is possible to restrain rain water from being attached to the connection surface 40.

FIG. 5 is a perspective view illustrating the connecting portion 32. As illustrated in FIG. 5, the protruding portion 41 is formed in a shape of eaves. The protruding portion 41 includes an upper wall portion 50, and a suspended portion 51 extending downward from a forefront part of the upper wall portion 50.

The cover 42 includes an engagement portion 53 engaged with the engagement groove formed in the suspended portion 51. When the cover 42 is engaged with the protruding portion 41, the connection surface 40 is covered with the protruding portion 41 and the cover 42. This makes it possible to restrain rain water or the like foreign matters from being attached to the connection surface 40.

A recessed portion 55 is faulted in an edge of the cover 42, and a scupper hole 58 is formed in the cover 42. When the cover 42 is engaged with the protruding portion 41, a drawing hole 57 from which a cord of an electric plug is drawable is formed by the recessed portion 55 and the protruding portion 41.

The scupper hole 58 is formed on a bottom part of the cover 42, and serves as a hole from which foreign substances such as water getting through the cover 42 is discharged outside. Here, in FIG. 4, when a virtual straight line extending from the scupper hole 58 in a direction where the scupper hole 58 extends is taken as a virtual straight line 59, the connection surface 40 is provided at a position away from the virtual straight line 59. That is, the scupper hole 58 is formed so that the virtual straight line 59 does not pass through the connection surface 40.

As illustrated in FIG. 4, in a state where the cover 42 is closed, even if scattered rain water comes inside the cover 42 through the scupper hole 58, it is possible to restrain the rain water or the like foreign matters from being attached to the connection surface 40.

In FIG. 5, the seal 43 includes a seal 60 provided on a bottom end surface of the suspended portion 51, a seal 61 provided in the cover 42, and a seal 62 provided in the cover 42. The seal 60 is formed in an elongated shape. Note that an air gap may be formed within the seal 60 formed in a column shape.

The seal 61 is provided on an inner side of the cover 42 at a position adjacent to the recessed portion 55.

The seal 62 is provided on that side of the seal 61 which is opposite to the recessed portion 55. Accordingly, in a state where the cover 42 is engaged with the protruding portion 41, the seal 61 is provided so as to adjacent to a connection-surface-40 side of the drawing hole 57. In a state where the cover 42 is engaged with the protruding portion 41, the seal 62 is placed closer to the connection surface 40 than the seal 61.

In a state where the cover 42 is engaged with the protruding portion 41, the seal 62 makes contact with the seal 60.

FIG. 6 is a perspective view illustrating the seal 43 in a state where the cover 42 is engaged with the protruding portion 41. As illustrated in FIG. 6, when the cover 42 is engaged with the protruding portion 41, the seal 60 makes contact with the seal 62.

A slit portion 65 is formed in the seal 61, and due to the slit portion 65, the seal 61 is divided into a seal piece 63 and a seal piece 64.

The slit portion 65 includes a slit portion 67 extending in an opening and closing direction 66 of the cover 42, a slit portion 68 formed in the seal piece 63, and a slit portion 69 formed in the seal piece 64.

The slit portion 68 is formed so as to extend from an edge of the slit portion 67 in a direction intersecting with the opening and closing direction 66. Note that a plurality of slit portions 68 is formed in the seal piece 63 at intervals in the opening and closing direction 66. Hereby, a plurality of piece portions 70 is formed in the edge of the slit portion 67 of the seal piece 63 at intervals in the opening and closing direction 66.

The slit portion 69 is formed so as to extend from the edge of the slit portion 67 in the direction intersecting with the opening and closing direction 66. Note that a plurality of slit portions 69 is formed in the seal piece 64 at intervals in the opening and closing direction 66. Hereby, a plurality of piece portions 71 is formed in the edge of the slit portion 67 of the seal piece 64 at intervals in the opening and closing direction 66.

FIG. 7 is a perspective view illustrating the connecting portion 32 in which the protruding portion 41 and the cover 42 are omitted. As illustrated in FIG. 7, the loop wall portion 44 includes: a top plate portion 75 provided above the connection surface 40 and protruding outwardly; a side wall portion 76 and a side wall portion 77 extending upward from respective positions laterally distanced from the connection surface 40; and frame portions 78, 79, 80.

The side wall portion 76 is formed to hang downward from one end of the top plate portion 75, and the side wall portion 77 is formed to hang downward from the other end of the top plate portion 75. The side wall portions 76, 77 are formed such that their heights (heights from the end surface 39) become higher as the side wall portions 76, 77 go toward the top plate portion 75 from lateral sides of the connection surface 40.

The frame portion 78 is formed to extend downward from a lower end of the side wall portion 76. The frame portion 79 is also formed to extend downward from a lower end of the side wall portion 77. The frame portion 80 is formed to extend along a lower hem portion of the end surface 39, and the frame portion 80 connects a lower end of the frame portion 78 to a lower end portion of the frame portion 79.

Since the loop wall portion 44 is formed in a loop shape as such, even if the power extraction device 30 is used under an environment such as rain; it is possible to restrain rain water or the like foreign matters from being attached to the connection surface 40.

Further, since the side wall portion 76 and the side wall portion 77 having a high height, even if rain or the like is blown thereto in a diagonal direction, it is possible to restrain the rain water or the like foreign matters from being attached to the connection surface 40.

FIG. 8 is a side view schematically illustrating a vicinity of a lower end of the connecting portion 32. As illustrated in FIG. 8, even in a state where the cover 42 is closed, a slight gap is formed between a lower end of the body portion 34 and the cover 42. In the meantime, since the frame portion 80 is provided along the lower hem portion of the end surface 39, even if rain water or the like foreign substances comes inside, it is possible to restrain the rain water from being attached to the connection surface 40 illustrated in FIG. 7.

FIG. 9 is a side view of the power extraction device 30 in a state where an engaged state between the cover 42 and the protruding portion 41 is disengaged and the cover 42 is opened.

In FIG. 10, the connecting portion 31 is connected to the charging portion 21. After that, the cover 42 is opened, and the electric plug 82 is connected to the connection surface 40.

When the electric plug 82 is connected to the connection surface 40, the user applies a pressing force thereto in a direction perpendicular to the connection surface 40. The pressing force applied to the power extraction device 30 is supported by a connection part between the end of the body portion 33 and the vehicle 10.

Here, a region where the connection surface 40 is projected in a direction perpendicular to the connection surface 40 from a position apart from the connection surface 40 is taken as a projection region R1. The projection region R1 passes through that end of the body portion 33 at which the connecting portion 31 is provided. FIG. 11 is a schematic view schematically illustrating a positional relationship between the end of the body portion 33 and the projection region R1. As illustrated in FIG. 11, the projection region R and the end of the body portion 33 overlap with each other.

Because of this, a rotation moment added to the connection part between an end of the power extraction device 30 and the vehicle 10 is reduced due to the pressing force applied by the user. This makes it possible to restrain the forefront part of the power extraction device 30, the charging portion 21 of the vehicle 10, and the like from being damaged.

FIG. 12 is a perspective view illustrating the connecting portion 32 and its vicinal area in a state where the electric plug 82 is connected to the connection surface 40.

Accordingly, when the electric plug 82 is attached, the user is able to attach the electric plug 82 to the connection surface 40 while checking the connection surface 40 and the electric plug 82.

FIG. 13 is a perspective view illustrating a state where the cover 42 is closed from the state illustrated in FIG. 12. As illustrated in FIG. 13, the cover 42 is rotated in a closing direction 84, so as to hook the engagement portion 53 to an engagement groove 52 formed in the protruding portion 41. Hereby, the cover 42 is fixed to the suspended portion 51.

When the cover 42 is fixed to the suspended portion 51, the electric plug 82 and the connection surface 40 illustrated in FIG. 12 are covered with the cover 42 and the protruding portion 41, thereby making it possible to restrain rain water or the like foreign matters from coming inside the cover 42. The cord 83 is drawn outside from the drawing hole 57.

FIG. 14 is a perspective view illustrating the seals 60, 61, 63, and the cord 83 in a state where the cover 42 is fixed to the protruding portion 41 as illustrated in FIG. 13. As illustrated in FIG. 14, when the cover 42 is rotated in the closing direction 84, the seal 61 and the seal 62 provided in the cover 42 are also displaced in the closing direction 84. Part of the seal 62 makes contact with the seal 60, and the cord 83 is sandwiched between the seal 60 and the seal 62. Further, the cord 83 comes inside the seal 61 from the slit portion 67.

FIG. 15 is a front view illustrating the seal 60, the seal 62, and the cord 83 illustrated in FIG. 14. As illustrated in FIG. 15, when the cord 83 is sandwiched between the seal 60 and the seal 61, gaps 85 are formed on lateral sides of the cord 83 by the cord 83, the seal 60, and the seal 62.

As illustrated in FIG. 14, the plurality of piece portions 70 is formed in the seal piece 63 of the seal 61, and the plurality of piece portions 71 is also formed in the seal 61. When the cord 83 comes inside the slit portion 67, the piece portions 70 and the piece portions 71 are pushed out by the cord 83, so that the piece portions 70, 71 make contact with the cord 83.

Accordingly, the gaps 85 formed on the lateral sides of the cord 83 are covered with the plurality of piece portions 70, 71 placed on the lateral sides of the cord 83.

As a result, as illustrated in FIG. 13, in a state where the cover 42 is fixed to the suspended portion 51, it is possible to restrain rain water or the like foreign matters from coming inside the cover 42 from the drawing hole 57.

As such, according to the power extraction device 30 of Embodiment 1, when the power extraction device 30 is used, it is possible to restrain rain water or the like foreign matters from coming inside the cover 42.

Further, even if rain water or the like comes inside the cover 42, it is possible to discharge outside the rain water or the like foreign matters from the scupper hole 58 illustrated in FIG. 4. Note that the vehicle 10 according to Embodiment 1 deals with an example in which the power extraction device 30 is connected to the charging portion 21 configured to cause the battery B to receive electric power.

The seal 143 extends along a shape of the recessed portion 55 and is formed in an arc shape. The seal 144 also extends along a shape of the recessed portion 90 and is formed in an arc shape. Note that an opening gap portion is formed in each of the seal 143 and the seal 144, and sectional diameters of the seal 143 and the seal 144 are changed due to an external force applied thereto from their outside.

Accordingly, in a state where a cord 83 is not drawn, for example, the seal 143 and the seal 144 make close contact with each other, so that a gap between the seal 143 and the seal 144 is closed.

As illustrated in FIG. 37, when the cord 83 is drawn from the cover 42, the seal 143 and the seal 144 are deformed, so that an insertion hole 145 is formed.

FIG. 38 is a front view of the seal 95 in a state where a cord 83 having a smaller diameter than the example illustrated in FIG. 37 is drawn from the cover 42.

As illustrated in FIG. 38, when the cord 83 having a small diameter is drawn, sectional diameters of the seal 143 and the seal 144 become larger than a case illustrated in FIG. 37. A peripheral surface of the cord 83 having a small diameter makes close contact with the seal 143, and the peripheral surface of the cord 83 makes close contact with the seal 144, successfully.

As such, according to the seal 95 illustrated in FIGS. 37 and 38, even if any cords 83 having various diameters are drawn therefrom, it is possible to restrain rain water or the like foreign matters from coming inside the cover 42.
