Is fitted to the vehicle-side connector 105. The device-side connector 31 is moved between the standby position and the fitting position via the opening 3a 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 fitting position is a position where the device-side connector 31 is fitted to the vehicle-side connector 105 when the connector lifting / lowering mechanism of the connector lifting / lowering portion 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 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 controls the driving of the wheel stopper 12A based on the connector position information received from the vehicle 100 by the communication unit 11. 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.

  The control unit 16 determines the stop position of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the connector position information, and controls the vehicle stop member 20 that can stop the vehicle 100 at the stop position. A protruding signal for protruding is output. The control unit 16 compares, for example, the preset reference values S1 and S2 with the separation distance L, sets the stop position N when L <S1, and stops when S1 <L <S2. The position is M, and if L> S2, the stop position is F. Subsequently, the control unit 16 selects a stop member 20 that can stop the vehicle 100 at the determined stop position from among the plurality of stop members 20a to 20c, and outputs a protrusion signal corresponding to the selected stop member 20 to the stop position. Output to the unit 12A. For example, when the control unit 16 determines the stop position N, the control unit 16 selects the wheel stop member 20c corresponding to the stop position N, and outputs a protrusion signal corresponding to the wheel stop member 20c. Alternatively, when the control unit 16 determines the stop position M, the control unit 16 selects the wheel stop member 20b corresponding to the stop position M and outputs a protrusion signal corresponding to the wheel stop member 20b. Alternatively, when the control unit 16 determines the stop position F, the control unit 16 selects the wheel stop member 20a corresponding to the stop position F, and outputs a protrusion signal corresponding to the wheel stop member 20a. That is, the wheel stopper 12 </ b> A causes one of the three vehicle stopper members 20 a to 20 c to protrude from the ground 120 in accordance with the protruding signal from the controller 16.

  The control unit 16 receives a sensor output signal output from a piezoelectric sensor or the like of the vehicle stop member 20 protruding from the ground 120 and determines whether or not a wheel has contacted the vehicle stop member 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 mating position. 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, a charging operation in the vehicle charging device 1A will be described with reference to a flowchart of FIG. Each step described below is executed by the control unit 16 in principle.

  First, 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 causes the bollard corresponding to the connector position information to protrude. For example, when the connector position information is the separation distance L1, the control unit 16 determines the stop position N of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the separation distance L1. The control unit 16 sends a protruding signal for projecting the rearmost one of the three vehicle stop members 20a to 20c to the vehicle stop unit 12A as the vehicle stop member 20 that can stop the vehicle 100 at the determined stop position N. Output to Further, for example, when the connector position information is the separation distance L2, the control unit 16 determines the stop position M of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the separation distance L2. . The control unit 16 outputs a protruding signal for protruding the centrally located wheel stop member 20b among the three wheel stop members 20a to 20c as the wheel stop member 20 that can stop the vehicle 100 at the determined stop position M. Output to

  Next, in step S3, the control unit 16 determines whether or not the wheel (here, the front wheel 101) of the vehicle 100 has come into contact with the stop member 20 protruding from the stop 12A. For example, the control unit 16 determines whether the vehicle 100 has stopped in response to receiving a sensor output signal from a piezoelectric sensor or the like provided on the vehicle stop member 20. When the control unit 16 determines that the wheel has come into contact with the vehicle stop member 20, the process proceeds to step S4.

  Next, in step S4, 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 S5, 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 S6.

  Next, in step S6, 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 S7, 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 determining that the charging is completed, the control unit 16 proceeds to step S8.

  Next, in step S8, 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 storage of the device-side connector 31 under the ground 120 is completed, the connector elevating unit 14 outputs a completion signal to the control unit 16.

  In step S9, when the storage of the device-side connector 31 by the connector lifting / lowering unit 14 is completed, the control unit 16 outputs a storage signal to the vehicle stopping unit 12A. The vehicle stop 12A stores the vehicle stop member 20 protruding from the ground 120 below the ground in response to the received storage signal, and ends this processing.

  In the vehicle charging device 1A described above, the control unit 16 determines the stop position of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the connector position information received from the vehicle 100, A protruding signal for protruding the stop member 20 that can stop the vehicle 100 at the stop position is output to the stop portion 12A. The vehicle stop 12A includes a plurality of vehicle stop members 20 arranged in the front-rear direction of the vehicle 100, and causes the corresponding vehicle stop member 20 to protrude from the ground 120 in response to a protruding signal from the control unit 16. With the above configuration, the vehicle 100 can be stopped at a plurality of stop positions in accordance with the plurality of stop members 20, and the vehicle 100 is stopped in accordance with a stop position where the device-side connector 31 can be fitted to the vehicle-side connector 105. be able to.

  The vehicle charging device 1 </ b> A is configured such that each vehicle stop member 20 can be stored under the ground 120 in response to completion of charging of the battery in the vehicle 100. Thereby, after the vehicle 100 enters the parking area 3 from the front and performs charging, the vehicle 100 can exit the parking area 3 forward. Generally, it is easier for the driver of the vehicle 100 to move the vehicle 100 forward than to retreat, so that the usability of the vehicle charging device 1A can be improved. In addition, when the vehicle 100 is a bus or the like, it is possible to reduce the burden on the driver by moving forward and leaving the parking area 3.

It has a shape member. In response to the protruding signal from the control unit 16, the wheel stopper 12 </ b> B moves the adjacent two or more plate-like members (wheel stoppers 40 c to 40 g) into a protruding height as shown in FIG. 5. The vehicle 100 is projected so as to gradually decrease from the front to the rear. The protruding height of the plate-like member group is set on the outer peripheral surface of the front wheel 101 of the vehicle 100 between the horizontal plane and the vertical plane passing through the axle O and in accordance with the outer peripheral curved surface of the wheel between the horizontal plane and the ground 120.

  The control unit 16 according to the modified example determines a stop position of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the connector position information, and can stop the vehicle 100 at the stop position. A protruding signal for protruding the plate member group is output. The control unit 16 compares, for example, a plurality of preset reference values Sn (n = 1, 2,..., I + 1) with the separation distance L. If Sn <L <S (n + 1), Stop position N is assumed. Subsequently, the control unit 16 selects and selects two or more adjacent plate-like member groups including the vehicle stop member 40n that can stop the vehicle 100 at the determined stop position N from the plurality of vehicle stop members 40a to 40i. A protruding signal corresponding to the set of plate-like members is output.

In addition, two or more adjacent plate-like member groups are projected so that the projecting height of the plate-like member group gradually decreases from the front to the rear of the vehicle 100. Accordingly, the protruding height of the plate-shaped member group is formed according to the outer peripheral curved surface of the wheel, so that the number of contact points between the outer peripheral curved surface of the wheel and the plate-shaped member group can be increased, and the vehicle can be effectively stopped. be able to. In the vehicle charging device 1A according to the modified example, the control unit 16 determines a stop position of the vehicle 100 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the connector position information, And outputs a protruding signal for protruding the group of plate members capable of stopping the vehicle 100. Thereby, the same effect as in the first embodiment can be obtained.

[Second embodiment]
Next, a vehicle charging device 1B according to a second embodiment of the present invention will be described with reference to FIGS. The vehicle charging device 1B is different from the vehicle charging device in that the vehicle stopping portion 12C has one vehicle stopping member 24 and the connector lifting / lowering portion 14 is configured to be movable in the front-rear direction of the vehicle 100 by the connector moving portion 13.

  The vehicle stop 12C has a vehicle stop mechanism including an actuator, a sensor, and the like, and stops the vehicle 100 that is in contact with the wheels of the vehicle 100 by the vehicle stop mechanism. The vehicle stop 12C is stored, for example, in a space below the ground 120 in front of the parking area 3 in the front-rear direction, and stops the front wheel 101 of the vehicle 100. The vehicle stopper 12C is provided for each of the right front wheel 101 and the left front wheel 101 in the width direction of the vehicle 100. The wheel stopper 12C is electrically connected to the controller 16 and is driven in accordance with, for example, a protrusion signal received from the controller 16. The vehicle stopper 12C has a vehicle stopper 24 disposed in front of the vehicle 100 and projecting from the ground 120 in response to a projection signal received from the controller 16. That is, the wheel stopper 12 </ b> C causes the vehicle stopper 24 to protrude from the ground 120 in response to the protruding signal from the controller 16.

  The wheel stopper member 24 is formed of metal such as iron or stainless steel, hard plastic, or the like. The cross-sectional shape of the wheel stopper member 24 as viewed from the width direction is formed in a triangular shape. The wheel stopper member 24 is arranged such that one of the outer peripheral surfaces thereof comes into contact with the outer peripheral surface of the front wheel 101 in a protruding state protruding from the ground 120. On the other hand, when the vehicle stop member 24 is stored under the ground 120, it is installed such that the surface that has contacted the outer peripheral surface of the front wheel 101 is flush with the ground 120. When transitioning between the retracted state and the protruding state, the wheel stopper 24 is configured to rotate around, for example, one of the three corners on the outer peripheral surface as the center of the rotation axis. It is preferable that the vehicle stop member 24 is set such that the height of the protrusion from the ground 120 in the above-mentioned protruding state is a height at which the front wheel 101 of the vehicle 100 cannot easily get over. Further, it is preferable that the brace member 24 is set such that the height of the upwardly extending portion from the ground 120 in the above-mentioned protruding state is substantially the same. For example, the vehicle stopping member 24 protrudes from the ground 120 when the vehicle 100 enters the parking area 3, and is stored in a space below the ground 120 when leaving the parking area 3. The vehicle stop member 24 includes a piezoelectric sensor or the like on a surface on which the wheel contacts as detection means for detecting contact of the wheel. The detecting unit such as a piezoelectric sensor is electrically connected to the control unit 16 and outputs a sensor output signal to the control unit 16.

As shown in FIG. 6, for example, the connector moving unit 13 is housed in a space below the ground 120 that communicates with an opening 3a provided substantially at the center in the front-rear direction and the width direction of the parking area 3. The connector moving unit 13 is electrically connected to the control unit 16 and is driven according to, for example, a movement signal received from the control unit 16. When the vehicle 100 is stopped by the vehicle stopper 12C, the connector moving unit 13 moves the connector elevating unit 14 from the standby position to the device-side connector 31 and engages with the vehicle-side connector 105 in response to a movement signal from the control unit 16. To the destination position.

  The control unit 16 determines a destination position of the connector elevating unit 14 at which the device-side connector 31 can be fitted to the vehicle-side connector 105 based on the connector position information, and moves the connector elevating unit 14 to the destination position. It outputs a movement signal that can be. The control unit 16 calculates a difference by comparing the distance between the virtual line P and the connector elevating unit 14 at the initial position with the separation distance L, as shown in FIG. 6, for example. The control unit 16 calculates a moving direction and a moving distance of the connector elevating unit 14 based on the calculated difference, and determines a destination position corresponding to the moving direction and the moving distance. The control unit 16 outputs to the connector moving unit 13 a destination signal that can move the connector elevating unit 14 to the destination position. The control unit 16 moves the connector elevating unit 14 to the destination position by the connector moving unit 13, and then sends an elevating signal to the connector elevating unit 14 to raise the device-side connector 31 from the destination position to the fitting position. Let it.
