  The transporter 12 </ b> A transports the stopped vehicle 100 having at least one stop 20 formed on the mounting surface 22 a of the vehicle 100 and stopping at the stop 20 at the parking position. Here, the parking position is a position of the vehicle 100 in a state where the transporter 12A has stopped driving and the vehicle 100 has entered the mounting surface 22a of the transporter 12A and stopped at the bollard 20. The transporter 12A of the present embodiment is, for example, a belt-conveyor-type transporter, and is disposed on the right side and the left side in the width direction of the vehicle 100, respectively. That is, the transporter 12A is divided into two so that the apparatus-side connector 31 does not overlap with the transporter 12A in the vertical direction. The two transporters 12A are arranged in parallel along the front-back direction of the vehicle 100, and can be driven at the same time to transfer the stopped vehicle 100 in the front-rear direction. The transporter 12A is configured to include a bollard 20, a driving roller 21A, a driven roller 21B, and an endless belt 22. The vehicle stop 20 comes into contact with the front wheels 101 of the vehicle 100 to stop the vehicle 100. A plurality of the bollards 20 are arranged on the outer peripheral surface of the endless belt 22 at regular intervals. The wheel stopper 20 is formed of metal such as iron or stainless steel, hard plastic, or the like. The cross section of the wheel stop 20 as viewed from the width direction is formed in a triangular shape. The wheel stop 20 is configured such that one of the three outer peripheral surfaces is fixed to the mounting surface 22a, and the other one surface is in contact with a part of the outer peripheral surface of the front wheel 101. The wheel stop 20 includes, for example, a piezoelectric sensor or the like on a surface with which the front wheel 101 abuts, as a detecting unit for detecting the abutment of the wheel (here, the front wheel 101). The detection means is electrically connected to the control unit 16 and outputs a sensor output signal to the control unit 16. The drive roller 21A is connected to a drive motor (not shown), and is driven to rotate by the drive motor. The driven roller 21B is driven and rotated by the rotation of the driving roller 21A via the endless belt 22. The endless belt 22 is wound around a driving roller 21A and a driven roller 21B, and an outer peripheral surface forms a mounting surface 22a of the vehicle 100. The transporter 12A is electrically connected to the control unit 16 and is driven according to, for example, a drive signal received from the control unit 16. The transporter 12 </ b> A transports the vehicle 100 from the storage position to a fitting position where the device-side connector 31 can be fitted to the vehicle-side connector 105 in response to a drive signal from the control unit 16. The fitting position is, for example, as shown in FIGS. 1 and 2, the center position of the device-side connector 31 in the front-rear direction, and is the position of the virtual line S.

  The connector elevating unit 14 is extendable and contractible in the vertical direction of the vehicle 100, has a connector elevating mechanism including an actuator, a sensor, and the like (not shown), and elevates and lowers the device-side connector 31 by the connector elevating mechanism. Things. As shown in FIGS. 1 to 3, the connector elevating unit 14 is located below the transport path of the vehicle 100 and is disposed between the two transporters 12 </ b> A. For example, when the connector elevating mechanism is configured by a pantograph or the like, the connector elevating unit 14 is provided with the device-side connector 31 at a destination where the pantograph extends in the expansion and contraction direction. The device-side connector 31 is a power supply port on the vehicle charging device 1A side, and is electrically connected to the charging unit 15 via a cable (not shown) or the like. The device-side connector 31 is fitted to the vehicle-side connector 105 and is electrically connected to the vehicle-side connector 105. The connector elevating unit 14 is electrically connected to the control unit 16 and is driven in accordance with, for example, an elevating signal received from the control unit 16. In the stopped state, the connector elevating unit 14 fits the device-side connector 31 to the vehicle-side connector 105 by raising the device-side connector 31 from the standby position to the position in response to the elevating signal from the control unit 16. Let it. The device-side connector 31 is moved between the standby position and the ascending position by the connector elevating unit 14. This standby position is a position where the connector lifting mechanism of the connector lifting unit 14 is in a bent state and the device-side connector 31 is stored in a space below the ground 120. The ascending position is a position where the device-side connector 31 is fitted to the vehicle-side connector 105 when the connector elevating mechanism of the connector elevating unit 14 is in the extended state. It is preferable that the device-side connector 31 and the vehicle-side connector 105 have a structure that can be securely fitted even when their relative positions are slightly shifted in the width direction.

  The charging unit 15 charges the vehicle 100 in accordance with a charging signal from the control unit 16 in a state where the device-side connector 31 is fitted to the vehicle-side connector 105. The charging unit 15 is electrically connected to an external power supply (not shown) including a commercial power supply and the like. The charging unit 15 starts or ends charging of the vehicle 100-side battery from the external power supply in accordance with the charging signal received from the control unit 16 in the fitted state. In addition, the charging unit 15 can measure the current flowing from the external power supply to the vehicle-side battery and transmit the current value to the control unit 16 in the fitted state.

  The control unit 16 is electrically connected to the communication unit 11, the transporter 12A, the connector elevating unit 14, and the charging unit 15, and controls them. The control unit 16 includes, for example, a central processing unit such as an MPU (Micro Processing Unit), an electronic circuit mainly composed of a known microcomputer including a ROM (Read Only Memory), a RAM (Random Access Memory), and an interface. Be composed. The control unit 16 specifies the entry connector position, which is the position of the vehicle-side connector 105 at the entry position, based on the connector position information input from the communication unit 11, and moves the vehicle 100 from the entry connector position to the fitting position. The driving signal to be conveyed is output. As shown in FIGS. 1 and 2, for example, the connector position at the time of entry is the center position of the vehicle-side connector 105 in the front-rear direction and the position of the imaginary line R in the stopped state. In the above-mentioned stopped state, the control unit 16 determines the distance between the position of the vehicle stop 20 and the connector position at the time of entry based on the estimated distance and the separation distance L between the vehicle stop 20 contacting the wheel and the reference position in the front-rear direction of the vehicle 100. Specify the relative position. The control unit 16 calculates a distance M from the specified incoming connector position to the position of the device-side connector 31 and transmits a drive signal that can cause the vehicle 100 to be transported from the incoming connector position to the above-described fitting position. Output to 12A.

  The control unit 16 receives a sensor output signal output from a piezoelectric sensor or the like of the wheel stop 20 protruding from the mounting surface 22a, and determines whether a wheel has contacted the wheel stop 20. In the stopped state, the control unit 16 drives the connector elevating unit 14 by transmitting an elevating signal to the connector elevating unit 14, and raises the device-side connector 31 from the standby position to the ascending position to thereby increase the device side. The connector 31 is fitted to the vehicle-side connector 105. The control unit 16 transmits a charging signal to the charging unit 15 in the above-described fitted state, thereby causing the charging unit 15 to start charging the vehicle 100-side battery. The control unit 16 determines the state of charge of the vehicle-side battery based on the supplied current value received from the charging unit 15, and ends charging the vehicle-side battery according to the determined state of charge.

  Next, the transporting and charging operations in the vehicle charging device 1A will be described with reference to the flowcharts of FIGS. Each step described below is executed by the control unit 16 in principle.

  In FIG. 5, in step S1, the control unit 16 determines whether the communication unit 11 has received connector position information. When receiving the connector position information from the communication unit 110 of the vehicle 100, the communication unit 11 outputs the received connector position information to the control unit 16. The control unit 16 determines that the connector position information has been received according to the connector position information input from the communication unit 11, and shifts to step S2.

  Next, in step S2, the control unit 16 determines whether or not the wheel (here, the front wheel 101) of the vehicle 100 abuts the wheel stop 20. For example, the control unit 16 receives a sensor output signal from a piezoelectric sensor or the like provided on the vehicle stop 20, and determines whether or not the vehicle 100 has stopped according to the reception. When the control unit 16 determines that the front wheel 101 has come into contact with the vehicle stop 20, the process proceeds to step S3.

  Next, in step S3, the control unit 16 specifies the connector position at the time of storage based on the connector position information received in step S1, and calculates the distance M from the connector position at the time of storage to the position of the device-side connector 31. .

  Next, in step S4, the control unit 16 transports the vehicle 100 from the connector position at the time of storage to the fitting position where the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the distance M calculated in step S3. A drive signal that can be output is output to the transporter 12A. The transporter 12 </ b> A transports the vehicle 100 from the connector position at the time of storage to a fitting position where the device-side connector 31 can be fitted to the vehicle-side connector 105, according to the drive signal output from the control unit 16.

  Next, in step S5, the control unit 16 determines whether the movement of the vehicle 100 has been completed. For example, the control unit 16 determines whether or not the movement of the vehicle 100 has been completed according to the movement completion signal received from the transporter 12A. When the control unit 16 determines that the movement of the vehicle 100 has been completed, the process proceeds to a connector fitting process in step S6.

  6, in step S11, the control unit 16 outputs a lifting signal to the connector lifting unit 14. The connector elevating unit 14 raises the device-side connector 31 in accordance with the received elevating signal, thereby fitting the device-side connector 31 to the vehicle-side connector 105.

  Next, in step S12, the control unit 16 determines whether or not the device-side connector 31 has been fitted to the vehicle-side connector 105. The control unit 16 performs a connection test between the device-side connector 31 and the vehicle-side connector 105, for example, to determine the fitting. When the control unit 16 determines that the device-side connector 31 has been fitted to the vehicle-side connector 105, the process proceeds to step S13.

  Next, in step S13, control unit 16 outputs a charging signal to charging unit 15, and causes charging unit 15 to start charging a battery in vehicle 100.

  Next, in step S14, control unit 16 determines whether or not charging of battery in vehicle 100 by charging unit 15 has been completed. The control unit 16 determines whether or not the charging has been completed, for example, based on the current supplied to the charging unit 15. When the control unit 16 determines that the charging is completed, the process proceeds to step S15.

  Next, in step S15, the control unit 16 outputs a descending signal to the connector elevating unit 14 as an elevating signal. The connector lifting / lowering unit 14 separates the device-side connector 31 from the vehicle-side connector 105 by lowering the device-side connector 31 in response to the received lowering signal. When the lowering of the device-side connector 31 to the original standby position is completed, the connector elevating unit 14 outputs a completion signal to the control unit 16 and returns to step S7 in FIG.

  In FIG. 5, in step S7, upon receiving the completion signal from the connector elevating unit 14, the control unit 16 outputs a drive signal to the transporter 12A, and ends this processing. The transporter 12A transports the vehicle 100 to a predetermined exit position according to the received drive signal. Here, the unloading position is, for example, a position of the vehicle 100 in which the vehicle stop 20 that has stopped the vehicle 100 is detached from the wheels by the rotation of the endless belt 22 and the vehicle 100 can travel forward. In addition, the transporter 12A may transport the vehicle 100 to an exit position provided at a position different from the entrance position, or may transport the vehicle 100 to an exit position set at the same position as the entrance position, according to the drive signal. Good.

  In the vehicle charging device 1A described above, the transporter 12A moves the vehicle 100 from the parking position to the fitting position where the device-side connector 31 can be fitted to the vehicle-side connector 105 in response to the drive signal from the control unit 16. Transport. Based on the connector position information received from the vehicle 100, the control unit 16 specifies the entry-time connector position, which is the position of the vehicle-side connector 105 at the entry position, and transports the vehicle 100 from the entry-time connector position to the fitting position. A driving signal to be output is output. With the above configuration, the stopped vehicle 100 stopped at the parking position 20 at the parking position can be transported according to the fitting position, and the power receiving port on the vehicle 100 side and the power supply port on the vehicle charging device 1A side can be reliably connected. Can be fitted.

  In the first embodiment, when the vehicle charging device 1A is provided in a belt conveyor type car wash, the fitting position (that is, the charging position) of the device-side connector 31 is set on the transport path of the transporter 12A. For example, it is preferable to provide it in a place where the vehicle 100 after washing is dried.

That is, vehicle charging device 1B can transport vehicle 100 in a stopped state by transporter 12B, and stop vehicle 100 in accordance with a fitting position where device-side connector 31 can be fitted to vehicle-side connector 105. . As a result, the power reception port on the vehicle 100 side and the power supply port on the vehicle charging device 1A side can be securely fitted.

  In the second embodiment, when the vehicle charging device 1B is provided in the transport-type car wash, the fitting position (that is, the charging position) of the device-side connector 31 is changed, for example, to dry the vehicle 100 after the vehicle is washed. It is preferably provided at a location. When the vehicle charging device 1 </ b> B is provided in a horizontally movable parking lot, the charging position may be provided in each parking area of the vehicle 100.

  Further, in the second embodiment, the transporter 12B may be a pallet 42 provided in a facility such as a transport type car wash or a horizontally movable parking lot, but is applied to a lift type multi-level parking lot or the like. Gondola, lift, etc. In this case, the charging position described above may be provided, for example, at a descending position where a lift or the like that moves up and down comes to the lowest position. When the vehicle charging device 1 </ b> B is provided in a three-dimensional parking lot, the charging position may be provided in each parking area of the vehicle 100.

  Further, in the second embodiment, the wheel stop 20 is provided for each of the right front wheel 101 and the left front wheel 101 in the width direction of the vehicle 100. However, the present invention is not limited to this. One wheel stop 20 may be provided for the front wheel 101.

  Further, in the above-described second embodiment, the vehicle stop 20 is set so that the front wheel 101 does not easily climb over the projecting height from the mounting surface 42a, but is not limited thereto. For example, the wheel stop 20 may be set to a height at which the front wheel 101 can get over the protruding height. Thus, when leaving the vehicle, the vehicle 100 can get out of the vehicle in the same direction as when entering the vehicle, over the vehicle stop 20.

  Further, in the second embodiment, the wheel stop 20 is disposed in a state of being fixed to the mounting surface 42a, but is not limited to this. For example, the bollard 20 may be configured to protrude from the mounting surface 42a when the vehicle 100 enters the pallet 42 and to be stored in a space below the mounting surface 42a when the vehicle 100 leaves the vehicle.

(Modification)
In the first and second embodiments, the vehicle charging devices 1A and 1B charge the battery in the vehicle 100. However, the present invention is not limited to this. It may be configured to be able to receive.

  In the first and second embodiments, the vehicle-side connector 105 is disposed at the bottom of the vehicle body 103 and between the front wheel 101 and the rear wheel 102, but is not limited to this. For example, it may be arranged behind the rear wheel 102 or may be arranged ahead of the front wheel 101.

  In the first and second embodiments, the opening 42b preferably has a shutter opening / closing mechanism, and preferably has a configuration in which the shutter opens in conjunction with the reception of the connector position information.

  In the first and second embodiments, the vehicle 100 transmits the connector position information from the communication unit 110. However, the vehicle 100 may transmit the connector position information at all times, or may transmit the connector position information at a predetermined timing. . For example, the communication unit 11 of the vehicle charging devices 1A and 1B transmits a non-directional beacon signal at a fixed interval (for example, several seconds), and a response signal is received at a timing when the communication unit 110 of the vehicle 100 receives the beacon signal. May be configured to transmit the connector position information. Further, the vehicle 100 may be configured to transmit the connector position information from the communication unit 110 by a manual operation by the driver of the vehicle 100.

  Further, in the first and second embodiments, when the relative position between the device-side connector 31 and the vehicle-side connector 105 is shifted in the width direction, it is assumed that the displacement is absorbed by the structure of the connector itself. However, the present invention is not limited to this. For example, the deviation of the relative position between the connectors may be suppressed by using a guide described in JP-A-2015-82849. In this case, for example, as the connector position information, information for specifying the position of the vehicle-side connector 105 in the width direction of the vehicle 100 is added, and the guide described in the above publication is moved or the width of the guide is changed.
