In this case, the left and right front wheels of the vehicle are positioned on the left and right slide guides 55a and 55b to stop the vehicle.

  FIG. 13 shows a block configuration of the charging apparatus. The charging device includes a wheel detection sensor 62, a connection sensor 60a, a speaker 71, a switching circuit 72, and a control unit 70.

  The speaker 71 outputs a sound corresponding to the sound signal input from the control unit 70. The switching circuit 72 has a switch that is turned on / off in response to an instruction from the control unit 70, and the charging / discharging of the vehicle battery is started and stopped by turning on / off the switch.

  The control unit 70 is configured as a computer including a CPU, a memory, an I / O, and the like, and the CPU performs various processes according to programs stored in the memory.

  FIG. 14 shows a flowchart of the control unit 70. The control unit 70 periodically performs the process shown in FIG.

  First, it is determined whether or not a vehicle wheel has been detected based on a signal input from the wheel detection sensor 62 (100). If the vehicle wheel is not detected by the wheel detection sensor 62, the determination in S100 is NO, and the determination in S100 is repeated. Here, when the left and right front wheels of the vehicle are positioned on the left and right slide guides 55a and 55b, if the vehicle wheel passes over the wheel detection sensor 62, the determination in S100 is YES, and then the vehicle is stopped. Then, voice guidance is given to the driver of the vehicle so that the parking brake is applied (S102).

  Next, the accelerator operation of the vehicle is voice-guided (S104). Specifically, voice guidance is performed so that the accelerator is slowly depressed while the parking brake is applied with the position of the shift lever set to D “drive”. As a result, the left and right front wheels of the vehicle start rolling forward on the left and right slide guides 55a and 55b in a state where the parking brake is applied to the rear wheel of the vehicle and the vehicle stops moving. The inclined rollers 53a and 53b are rotated by the rotational force of the wheels, and as shown in FIG. 15, the slide guide 55a is moved to the right side and the slide guide 55b is moved to the left side by the rotation of the inclined rollers 53a and 53b.

  Then, as the distance between the slide guide 55a and the slide guide 55b becomes shorter, as shown in FIG. 16, the power supply connection portion 60 moves horizontally in the left-right direction of the vehicle and is provided in the center of the pedestal 59 together with the pedestal 59. The power feeding connection portion 60 rises with respect to the road surface.

  Next, based on the signal input from the connection sensor 60a, it is determined whether or not the power feeding connection unit 60 and the power receiving connection unit 31 are connected (S106).

  Here, when the power feeding connection unit 60 and the power receiving connection unit 35 are not connected, the determination in S106 is NO, and the determination in S106 is repeatedly performed. Further, when the left side surface of the left front wheel of the vehicle comes into contact with the wheel plate 54a and the right side surface of the right front wheel of the vehicle comes into contact with the wheel plate 54b, the power supply connection portion 60 is positioned in the center of the left and right wheels of the vehicle. When the vehicle rises with respect to the road surface and engages with the power receiving connecting portion 35 provided at the center of the left and right wheels at the bottom of the vehicle, the determination in S106 is YES, and then the vehicle is stopped so as to stop the rotation of the vehicle wheels. A voice guidance is provided to the driver (S108).

  Next, charge control is started (S110). Specifically, the switching circuit 72 is instructed to start charging, and when the charging of the vehicle battery is completed, the switching circuit 72 is instructed to stop charging.

  When the vehicle leaves the vehicle, if the driver slowly depresses the accelerator while the parking lever is applied with the position of the shift lever of the vehicle set to R “reverse”, the left and right front wheels of the vehicle slide into the left and right slide guides. Inversion starts on 55a and 55b. The tilting rollers 53a and 53b rotate in the opposite direction by the rotational force of the wheels, and the rotation of the tilting rollers 53a and 53b moves the left slide guide 55a to the left and the right slide guide 55b to the right. Then, as the distance between the left slide guide 55a and the right slide guide 55b becomes longer, the power feeding connecting portion 60 provided at the center of the pedestal 59 is lowered.

  In this state, the driver releases the parking brake and moves the vehicle backward to take the vehicle out of the charging space.

  According to the configuration described above, the power supply connection unit moving mechanism that receives the rotational force of the vehicle wheel 30 and moves the power supply connection unit 60 to a position where it is fitted to the power reception connection unit 35 is provided. Since the rotational force of the wheel 30 is transmitted to the power supply connection portion 60 and the power supply connection portion 60 moves to a position where the power supply connection portion 60 is fitted to the power reception connection portion 35, the connection portion is connected with a simpler configuration and the time required for the connection Can be shortened.

  In addition, the rotational force of the left and right wheels 30 of the vehicle is transmitted to the plurality of rollers 53a and 53b on the slide guides 55a and 55b, so that the power feeding connecting portion 60 moves horizontally in the left and right direction of the vehicle and the power feeding connecting portion 60 is moved relative to the road surface. The power feeding connection portion 60 that has risen with respect to the road surface can be configured to move to a position where the power receiving connection portion 35 is provided on the bottom of the vehicle.

  Further, the power receiving connection portion 35 is provided at the left and right center of the bottom portion of the vehicle, and the left and right wheels 30 of the vehicle rotating on the wheel plate are in contact with the wheel plates 54a and 54b provided at the left and right ends of the slide guides 55a and 55b. By configuring the power supply connection portion to be positioned at the center of the left and right wheels 30 of the vehicle, the power supply connection portion 60 can be moved to a position where the power supply connection portion 35 is fitted to the power reception connection portion 35 more reliably.

(Other embodiments)
In the first and second embodiments, when the power supply connection portion and the power reception connection portion are connected, the voice guidance is performed so as to stop the rotation of the vehicle. However, mutual communication is performed on the vehicle side and the charging device side, respectively. When it is determined that the power supply connection unit and the power reception connection unit are connected, a signal instructing the vehicle wheel to stop rotating is transmitted from the charging device side to the vehicle side via the communication device. The vehicle that has received this signal may be configured to forcibly stop the rotation of the wheels.

  Moreover, in the said 1st Embodiment, although the link rotation connection part 16c which supports the support member 16b rotatably was shown, the structure attached to the 1st plate 11 was shown, However, as a structure attached to the 2nd plate 12, Good.

  Further, in the second embodiment, with the left and right front wheels of the vehicle positioned on the left and right slide guides 55a and 55b, the vehicle parking brake is applied, and voice guidance is given so that the accelerator of the vehicle is slowly depressed. It is not always necessary to apply the vehicle parking brake. In the second embodiment, the configuration for charging a battery mounted on a front-wheel drive vehicle has been described as an example. However, for example, a configuration for charging a battery mounted on a rear-wheel drive vehicle may be used. In this case, the rear wheel of the vehicle may be rotated in a state where the rear wheel of the vehicle that is the driving wheel is positioned on the left and right slide guides 55a and 55b.
