(Embodiment 1)
As shown in FIGS. 2 and 3, the charging stand for an electric vehicle according to the present embodiment includes a stand main body 1 standing on the ground where the electric vehicle is parked, and a power cable (hereinafter referred to as a charging cable) for charging the electric vehicle. The plug 110 of 100 is provided with the outlet 20 which is inserted and connected to the insertion port 20a.

  The stand body 1 is a rectangular tube with front, top and bottom surfaces opened by assembling three metal plates (left side plate 2, right side plate 3, back plate 4) formed in a long rectangular plate shape. The opening on the top surface is closed by a flat box-shaped cover 5. On the inner side surfaces of the left side plate 2 and the right side plate 3, a mounting plate made of a rectangular plate-like metal plate and having a substantially central portion in the left-right direction (horizontal direction) bent in a step shape along the vertical direction (vertical direction) 6 is attached in parallel with the back plate 4 (see FIGS. 3 and 4). That is, the inside of the stand main body 1 is divided into front and rear by the mounting plate 6, and an outlet unit 10 described later is housed in a space in front of the mounting plate 6. (Not shown) is housed (wired) in the space behind the mounting plate 6. A plurality of screw holes 6a for attaching the outlet unit 10 and the earth leakage breaker 200 are provided in the mounting plate 6 at equal intervals along the vertical direction and the horizontal direction.

  A rectangular plate-like upper panel 7A and lower panel 7B are attached to the uppermost and lowermost parts of the front surface of the stand body 1. In the stand body 1, four storage spaces 8 for storing the outlet units 10 are juxtaposed in the vertical direction in the front space from the lower end of the upper panel 7 </ b> A to the upper end of the lower panel 7 </ b> B.

  As shown in FIG. 9, the outlet unit 10 includes a box-shaped casing 11 having an opening window 11a on the front surface, an outlet block 12 held in the casing 11, and a closed position for closing the opening window 11a (see FIG. 5). ) And an open position that opens the opening window 11a, and a door 13 that is rotatable in the horizontal direction, and a unit cover 16 made of a synthetic resin material that covers the top of the housing 11. As shown in FIG. 10, the casing 11 has a substantially central portion in the left-right direction of the back plate 11b bent in a step shape along the vertical direction (vertical direction), and the depth from the opening window 11a to the back plate 11b is large. The outlet block 12 is disposed at the corner on the large side (left side).

  The outlet block 12 has an outlet 20 provided with an insertion port 20a on the front surface of a rectangular box-shaped container 20b, and a fitting hole 21a into which the front end of the outlet 20 is fitted, and the outlet 20 is attached from the rear. A plate-shaped outlet panel 21 is provided. The outlet panel 21 is formed in a substantially hexagonal shape, and is attached to the left corner in the housing 11 so that the lower end is located rearward with respect to the upper end and the right end is located rearward with respect to the left end. Yes. The outlet 20 is housed in a space surrounded by the inner wall surface of the casing 11 and the outlet panel 21, and the outlet 20 a of the outlet 20 is exposed to the inner space of the casing 11 through the fitting hole 21 a of the outlet panel 21. . The outlet 20 is well known in the art, and is used for connecting a blade receiver (not shown) for receiving a contact (plug blade) of the plug 110 inserted from the insertion port 20a and an external electric wire. A terminal (not shown) is housed in a container 20b made of an insulating material.

  Thus, since the outlet panel 21 is mounted in the housing 11 so that the lower end is located rearward with respect to the upper end and the right end is located rearward with respect to the left end, the outlet attached to the outlet panel 21 is provided. 20, the insertion / extraction direction of the plug 110 with respect to the insertion port 20 a obliquely intersects the opening window 11 a in the horizontal direction and the vertical direction, in other words, the direction of the insertion port 20 a (the normal direction of the front surface of the outlet 20) is the opening window 11 a. (In the normal direction of the opening surface of the opening window 11a) is arranged so as to be inclined obliquely downward to the right (see FIG. 2).

  Here, as shown in FIG. 10, a terminal block 22 is attached to the back surface of the housing 11. The terminal block 22 is connected to a terminal of the outlet 20 through a through hole (not shown) having one connection terminal passing through the back plate 11b (actually, it is connected via a lock control device 23 described later). In addition, as will be described later, the electric wire connected to the secondary terminal of earth leakage breaker 200 is connected to the other connection terminal. That is, since the outlet 20 is housed in a space surrounded by the inner wall surface of the casing 11 and the outlet panel 21, the terminal block 22 is attached to the outside of the casing 11, and the terminals of the outlet 20 are connected to the outside via the terminal block 22. The connection work is facilitated by connecting the electric wires.

  The door 13 is formed in a flat rectangular box shape, and the left end is pivotally supported on the front left end of the housing 11 by a pair of upper and lower hinges 14 as shown in FIG. Moreover, the locking device 15 is attached to the back side of the door 13, and the key hole 15a of the locking device 15 is exposed on the front surface of the door 13 (see FIG. 2). When the door 13 is in the closed position, a gap (extraction port) for drawing out the charging cable 100 from the space between the lower end of the door 13 and the lower end on the front side of the housing 11 is vacant (see FIG. 2). ).

  The outlet unit 10 configured as described above is housed in the housing space 8 in the stand body 1 from the front side, and is fixed to the stand body 1 by screwing the housing 11 to the mounting plate 6. Is done. As described above, the four storage cavities 8 having the same dimensions are arranged in the vertical direction in the stand main body 1, and the outlet unit 10 can be stored in any of these four storage cavities 8. Here, a rectangular window hole 6 b is provided in the mounting plate 6 for each storage space 8, and the outlet unit 10 is mounted on the back surface of the housing 11 in a state where the outlet unit 10 is stored in the storage space 8. The terminal block 22 is inserted into the window hole 6b and exposed to the rear space (wiring space 9) of the mounting plate 6 (see FIGS. 11 to 13). However, in this embodiment, the case where the outlet unit 10 is stored in all the four storage spaces 8 is illustrated, but it is not always necessary to store the outlet unit 10 in all the four storage spaces 8, and at least 1 One outlet unit 10 may be stored in any one storage space 8.

  As shown in FIGS. 3 and 13, the earth leakage breaker 200 is attached to the back surface of the side (left side in FIG. 13) that protrudes forward of the mounting plate 6 and is disposed in the wiring space 9. In this wiring space 9, a power cable (not shown) for supplying AC power from a commercial AC power source is inserted from the cable inlet 1a on the bottom surface of the stand main body 1 and wired up (see FIG. 8). And while the electric power cable wired by the wiring space 9 is connected to the primary side of the earth leakage breaker 200, the secondary side of the earth leakage breaker 200 is connected to one connection terminal of the terminal block 22 by the electric wire which is not illustrated, The other connection terminal of the terminal block 22 is connected to the terminal of the outlet 20 through the lock control device 23. The wiring work described above can be easily performed by simply removing the back plate 4 of the stand body 1.

  Next, the lock device 15 and the lock control device 23 which are the gist of the present invention will be described.

  The locking device 15 includes a so-called cylinder lock, and as shown in FIGS. 1B and 9, the cylinder 151 and a locking piece 152 that protrudes in the radial direction from the tip of the cylinder 151 and rotates integrally with the cylinder 151. And a plunger 153 projecting into and out of the cylinder 151, a solenoid (not shown) for displacing the plunger 153, the cylinder 151, the lock piece 152, the plunger 153, and the solenoid are housed inside and the tip of the lock piece 152 And a box-shaped housing 150 having an insertion groove 150a through which the part is displaceably inserted. That is, when the solenoid is not excited, the plunger 153 advances into the cylinder 151 and engages with the key 17 inserted into the key hole 15a, thereby removing the key 17 and rotating (locking) the cylinder 151. When the solenoid is energized, the plunger 153 retreats from the cylinder 151 and does not engage the key 17 so that the key 17 can be removed and the cylinder 151 can be rotated (locked).

  Further, as shown in FIG. 1A, the lock control device 23 includes a detection unit 230 that detects whether or not the plug 110 is plugged into the insertion port 20a of the outlet 20, and the lock device 15. A key restricting portion 231 for restricting the extraction of the key 17 from the lock device 15 by switching between excitation and non-excitation of the solenoid, a power supply on / off portion 232 having a relay for opening and closing the power supply path from the terminal block 22 to the outlet 20, and light emission Key control according to a display unit 233 having a display element made of a diode, a door position detection unit 234 that detects the position (closed position) of the door 13, a detection result of the detection unit 230, and a detection result of the door position detection unit 234 A control unit 235 that controls the unit 231, the power supply on / off unit 232, and the display unit 233.

  The detection unit 230 includes a light emitting element that emits infrared light (for example, an infrared light emitting diode), a light receiving element that receives infrared light emitted from a red light emitting element (for example, a photodiode or a phototransistor), and a light emitting element. A light-emitting circuit that emits light; a light-receiving circuit that amplifies a light-receiving signal of the light-receiving element; and a comparison circuit that compares an output signal output from the light-receiving circuit with a threshold value, and is inserted into the outlet 20a of the outlet 20 A light emitting element and a light receiving element are arranged at positions facing each other across the connected plug 110. That is, when the plug 110 is not plugged into the insertion port 20a, the infrared light emitted from the light emitting element is received by the light receiving element without being blocked by the plug 110, so that the output signal exceeds the threshold value. When the plug 110 is plugged into the insertion port 20a, the infrared light emitted from the light emitting element is blocked by the plug 110 and is not received by the light receiving element, so the output signal falls below the threshold value. Based on the comparison result, it is possible to detect whether or not the plug 110 is plugged into the outlet 20 (plug 20a). However, the light receiving element may be arranged at a position where the infrared light emitted from the light emitting element can receive the reflected light reflected by the plug 110. In this case, when the plug 110 is not inserted and connected to the insertion port 20a, the infrared light emitted from the light emitting element is not reflected by the plug 110 and the reflected light is not received by the light receiving element, so that the output signal is a threshold value. When the plug 110 is plugged into the insertion port 20a, the reflected light reflected by the plug 110 from the infrared light emitted from the light emitting element is received by the light receiving element, so that the output signal has a threshold value. It will exceed.

  The door position detection unit 234 includes a switch (not shown) that pushes the push button 234a by a U-shaped drive piece 13a provided on the back surface of the door 13 that rotates in the horizontal direction. The position of the door 13 (closed position) can be detected when the push button 234a is pushed by the drive piece 13a and the switch is turned on.

  The display unit 233 is disposed inside the unit cover 16, and light emitted from the light emitting element is irradiated to the front of the unit cover 16 through the front wall of the unit cover 16 made of a translucent material. .

  When it is detected by the detection unit 230 that the plug 110 is not plugged in and connected to the outlet 20, the control unit 235 does not excite the solenoid in the key restriction unit 231 so that the key 17 inserted in the key hole 15a. Is prevented from being removed and the cylinder 151 is not rotated (not locked), and when the detection unit 230 detects that the plug 110 is plugged into the outlet 20, the solenoid is connected to the key restriction unit 231. By exciting the plunger 153 and retreating it from the cylinder 151, the cylinder 151 can be turned (locked) and the key 17 can be removed from the key hole 15a. Further, the control unit 235 detects that the door 13 is in the closed position by the door position detection unit 234 in a situation where the detection unit 230 detects that the plug 110 is plugged into the outlet 20. Sometimes, the power supply on / off unit 232 is controlled to supply power to the outlet 20. That is, in the present embodiment, the charging cable 100 is not supplied with power from the outlet 20 only by plugging the plug 110 into the insertion port 20a of the outlet 20, and the charging cable 100 is not connected from the outlet 20 until the door 13 is closed. Therefore, it is possible to prevent a hand from inadvertently touching the plug 110 or the charging cable 100 that is being charged. In the control unit 235, when the power supply on / off unit 232 is controlled to supply power to the outlet 20, the display unit 233 is controlled to cause the display element to emit light to display that power is being supplied.

  Next, the procedure for using the electric vehicle charging station of this embodiment will be described. First, the door 13 is opened, and the plug 110 is plugged into the outlet 20 by inserting the contact of the plug 110 of the charging cable 100 into the insertion port 20a. At this time, since the direction of the insertion port 20a is arranged so as to be inclined obliquely downward to the right with respect to the direction of the opening window 11a, a space (space) necessary for inserting and removing the plug 110 in the housing 11 is provided. The plug 110 can be sufficiently secured and the plug 110 can be easily inserted, and rainwater that falls into the housing 11 through the opening window 11a is difficult to be applied to the insertion port 20a even in rainy weather. However, even if the outlet unit 10 is arranged close to the right side in the housing 11 and the outlet 20 is disposed so that the direction of the insertion port 20a is inclined obliquely to the left and downward with respect to the direction of the opening window 11a. However, as in the present embodiment, it is generally considered that the outlet 20 is disposed so that the insertion port 20a is tilted diagonally downward to the right from the left position in the housing 11. Right-handed people have the advantage of making it easier to insert the plug 110.

  After the plug 110 is plugged into the outlet 20, the door 13 is closed, and the lock device 15 is locked by turning the key 17. Here, as in the case of the power pole described in Patent Document 1, when the outlet outlet of the outlet is almost directly facing the opening of the casing in which the outlet is stored, the plug is inserted into the outlet. The pull-out position of the plugged-in power cable and the position of the outlet of the outlet are substantially the same in the horizontal direction. For this reason, when multiple outlets are installed side by side in a vertical direction, the hanging power cable and the outlet of the lower outlet overlap each other when viewed from the front.Therefore, plug another power cable into the lower outlet. There is a problem that it becomes difficult to make a complicated connection. On the other hand, in the present embodiment, each outlet 20 is disposed in the outlet unit 10 so that the direction of the insertion port 20a is inclined obliquely downward to the right with respect to the direction of the opening window 11a. When the plug 110 is plugged into the outlet 20 and the charging cable 100 hanging from the opening window 11a is not overlapped with the outlet 20a of the lower outlet 20 when viewed from the front, another charging cable is connected to the lower outlet 20. The work of plugging and connecting 100 plugs 110 is facilitated.

  Further, as shown in FIG. 2, a plurality (three) of cable holders (holding bodies) 40 are attached to the outer peripheral surface (right side surface in the present embodiment) of the stand main body 1. As shown in FIGS. 4 and 5, the cable holder 40 is formed by bending a strip-shaped metal plate into a bowl shape having a substantially U-shaped cross section, and aligning the longitudinal direction with the vertical direction and the groove at the rear. The right side plate 3 of the stand main body 1 is screwed in the vicinity of the storage space 8 in the second to fourth stages from the top so as to face.

  Thus, if the charging cable 100 drawn out of the stand body 1 (front) through the opening window 11a (drawing outlet) is fitted into the groove and held by the cable holder 40, the plug is connected to the upper outlet 20. The door 13 of the lower outlet unit 10 can be opened and closed without obstructing the charging cable 100 to which 110 is connected. Further, even when the charging cable 100 is inadvertently pulled, the cable holder 40 holds the charging cable 100, so that the tension applied to the plug 110 is relieved, and the plug 110 is inserted into the outlet 20a of the outlet 20. It can be prevented from coming off. Here, since the three cable holders 40 are arranged at positions shifted in the front-rear direction of the stand body 1 along the vertical direction, the plurality of charging cables 100 held by the cable holder 40 do not interfere with each other. It is. Furthermore, in the present embodiment, the cable holder 40 that is relatively below is disposed at a position closer to the front of the stand body 1 than the cable holder 40 that is relatively above, so that it is relatively below Since the cable holder 40 located at the front is positioned closer to the front of the stand body 1 than the charging cable 100 held by the cable holder 40 relatively above (see FIG. 6), the cable holder 40 is relatively below. When the charging cable 100 is held by the cable holder 40 in the above, there is an advantage that the charging cable 100 held by the cable holder 40 relatively above does not get in the way.

  On the other hand, when charging of the electric vehicle is completed, the key 17 is inserted into the keyhole 15a and turned to unlock the lock device 15 and open the door 13, and the plug 110 is pulled out from the outlet 20a of the outlet 20. Here, since the power supply to the outlet 20 is turned off by the lock control device 23 when the door 13 is open, it is possible to prevent an electric shock accident when the plug 110 is inserted into and removed from the insertion port 20a of the outlet 20. .

  As described above, according to the present embodiment, the lock device 15 cannot be locked in a state where the plug 110 is not plugged into the outlet 20, and the lock device 15 is not locked unless the lock device 15 is locked. Since the key 17 cannot be removed, there is an advantage that it is possible to prevent the occurrence of a malfunction related to the lock device 15 of the door 13 (such as removal of the key 17).

(Embodiment 2)
The present embodiment is characterized in the configuration of the detection unit 230 of the lock control device 23, and other configurations and operations are the same as those in the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and illustration and description thereof are omitted.

  In this embodiment, the detection unit 230 includes a contact body 236 that protrudes from the inside of the door 13 into the opening window 11a so as to freely advance and retreat, and contacts the plug 110 that is plugged into the outlet 20, and the contact body 236 includes the opening window. 11a is off when not in contact with the plug 110, and when the contact body 236 is retracted from the opening window 11a (is in contact with the plug 110), the contact body 236. A switch 110 (not shown) that is turned on when the plug 110 is pushed, and the plug 110 is plugged into the outlet 20 based on the position of the contact body 236 in the forward / backward direction (switch on / off). Whether or not is detected.

  As shown in FIG. 14, the abutting body 236 is integrally formed with a band plate-shaped main portion 236a and an abutting portion 236b suspended downward from the front end of the main portion 236a, and a rear end portion of the main portion 236a. Is inserted through a through hole 13b formed in the rear surface of the door 13. Although not shown, the rear end portion of the main portion 236a inserted through the through hole 13b is supported so as to be slidable in the front-rear direction and elastically biased toward the rear, and the main portion 236a moves forward. The switch is turned on.

  The contact portion 236b is provided with a substantially semicircular cable insertion groove 236c having an open lower end side. That is, when the door 13 is closed with the plug 110 connected to the outlet 20, the contact portion 236b contacts the rear end portion of the plug 110, so that the main portion 236a moves forward and the switch is turned on. . At this time, the charging cable 100 is inserted into the cable insertion groove 236c provided in the contact portion 236b. Note that the contact portion 236b may contact the charging cable 100 instead of the plug 110.

  As described above, according to the present embodiment, whether or not the plug 110 is connected to the outlet 20 and the position (closed position) of the door 13 can be detected simultaneously by the detection unit 230. Since it also serves as the door position detecting means, there is an advantage that the configuration can be simplified as compared with the lock control device 23 in the first embodiment. Further, when the door 13 is closed, the contact portion 236b of the contact body 236 is in contact with the plug 110 (or the charging cable 100), so that the plug 110 is pulled out of the outlet 20 when the charging cable 100 is pulled. There is an advantage that can be prevented.
