FIG. 3 is a plan view of the charging tray.

Since the charging trays 1A to 1D have the same configuration, the charging tray 1A will be described here as a representative. The charging tray 1A has a rectangular plate-like configuration in a plan view, and a tray side current collector 13A capable of electrically contacting the power feeding terminal 12A and a power feeding terminal 12B capable of electrically contacting the lower surface side thereof. A tray side current collector 13B is provided. These tray-side current collectors 13A and 13B are respectively arranged at diagonal positions on the left and right of the charging tray 1A in the approach direction of the electric vehicle. In this way, the tray-side current collectors 13A and 13B are arranged at diagonal positions on the left and right sides of the charging tray 1A in the approach direction of the electric vehicle, respectively, and, as described above, in the charging space 8A and the charging space 8B. By arranging the power supply terminals 12A and 12B at diagonal positions, the charging tray 1A can be stored in the charging space 8A in the moving direction of the arrow A and can be stored in the charging space 8B in the moving direction of the arrow B. Can be stored. In addition, by disposing the tray-side collectors 13A and 13B at diagonal positions on the left and right sides of the charging tray 1A in the approach direction of the electric vehicle, the mechanical parking device is provided with a turning device. Even when the charging tray 1A is turned by the turning device, the tray-side current collectors 13A and 13B can be opposed to the power supply terminals 12A and 12B without depending on the orientation of the charging tray 1A.

Further, in the corners on the upper surface side of the charging trays 1A to 1D, foldable charging stands 15A and 15B having charging outlets 14A and 14B electrically connected to the battery of the electric vehicle are provided. .. The tray-side current collectors 13A and 13B and the charging outlets 14A and 14B are electrically connected via the relay box 16 and the wiring 17.

A tray-side drive rail frame and the like that are paired with the side-drive device are configured. The floor drive device and the tray side drive rail frame may have various configurations. For example, the floor drive device may include a motor, a roller attached to a rotation shaft of the motor, and a rotation direction of the roller. It has a link device for switching, and is configured to move the EV tray 1A in an arbitrary direction by transmitting the rotational driving force of the roller by the motor to the tray-side driving rail frame.

In the first embodiment, when charging is performed while parking the electric vehicle by operating the operation panel, the control device selects, for example, the charging tray 1A, sets a charging reservation, and stores the charging reservation. At the same time, the charging tray 1A is prepared on the lift table 6 of the lift chamber 2. On the other hand, when parking of the general vehicle is selected by operating the operation panel, for example, the general tray 10A is prepared on the elevating table 6 of the elevating chamber 2.

When the charging tray 1A is prepared on the lift table 6 of the lift chamber 2, the door 3 of the lift chamber 2 is opened. Here, the driver of the electric vehicle loads the electric vehicle onto the charging tray 1A of the lift 6. After that, when the driver detects that the driver leaves the electric vehicle and goes out through the door 3 with a photoelectric detection device (not shown), and the operation switch of the lifting device is operated, the door 3 is closed.
Next, the control device gives a signal to the lift drive unit and the tray drive unit to convey the charging tray 1A to a storage space other than the charging space 8A or 8B, which is a storage area for storing general vehicles. After this time, the lifting device 4 can be prepared for the next loading/unloading. Here, the charging tray 1A in which the electric vehicle is mounted is not directly carried into the charging space but is once moved to the storage space. When carrying-in is carried out at any time according to this method, it is possible to store the electric vehicle reserved for charging using the charging trays having the number of charging spaces 8A and 8B or more. Moreover, since the electric vehicle for which the charging reservation is set is put on standby in the storage area, it is not necessary to limit the warehousing by the lift device 4, and the warehousing/unloading process can be efficiently performed.

After that, the control device determines whether the electric vehicle in the charging space 8A or 8B is in a charging completed state or whether the charging spaces 8A and 8B have a space. When the charging of the electric vehicle in the charging space is completed, the charged charging tray is moved to another storage space to form an empty space in the charging space. On the other hand, if there is no space in the charging space because another electric vehicle is being charged, the charging space is waited for until the charging is completed.

Here, when an empty space is formed in the charging space 8A, the control device controls the floor-side driving device and the tray-side driving rail frame, and the charging tray 1A for which charging reservation is set is stored in the storage space. It is moved to 9A and stored in the vacant charging space 8A in the moving direction shown by arrow A from this storage space 9A. On the other hand, when an empty space is formed in the charging space 8B, the charging tray 1A is moved to the storage space 9F and stored in the empty charging space 8B from the storage space 9F in the moving direction shown by the arrow B.

When the charging tray 1A is stored in the charging space 8A, the tray side current collector 13A is in electrical contact with the power supply terminal 12A, a charging circuit is formed, and charging is started. On the other hand, when the charging tray 1A is stored in the charging space 8B, the tray side current collector 13B is in electrical contact with the power supply terminal 12B to form a charging circuit, and charging is started.

The charging tray in which the fully charged electric vehicle is mounted can be stored in various ways. For example, the same charging tray can be stored as it is in the charging space and moved to the storage space as needed, or the charging tray can be moved from the charging space to the storage space at any time, and it can also be stored in the charging area at all times. The number can be set, and when the number exceeds the set number, the charging tray can be promptly controlled to move to the storage area.

In this way, the charging tray 1A in which the charged electric vehicle is mounted is moved to the storage space other than the charging space 8A or 8B, so that the number of electric vehicles to be parked increases. Even if the number of charging trays is increased by moving the charging tray with the charged electric vehicle mounted therein to the charging space 8A or 8B, an efficient charging service can be performed.

As described above, according to the mechanical parking apparatus of the present invention, the charging areas 8A and 8B for charging the electric vehicles mounted on the charging trays 1A to 1D are stored in the storage area formed on one floor. In addition to providing storage spaces 9A to 9H for storing electric vehicles and general vehicles that are not charged, charging trays 1A to 1D are provided with tray-side collector terminals 13A and 13B, and charging spaces 8A and 8B are provided. A plurality of charging spaces 8A are provided in a mechanical parking apparatus that includes power supply terminals 12A and 12B on the power source side that can be electrically connected to the tray-side current collecting terminals 13A and 13B and that can charge a battery of an electric vehicle during parking. , 8B are provided in the storage area, a plurality of charging trays 1A-1D are provided, and the tray-side current collecting terminals 13A, 13B are provided in each charging tray 1A-1D so as to correspond to two tray movement directions.

With this configuration, the degree of freedom in the layout of the charging space is increased, and the number of charging spaces in the storage area on one floor can be easily increased, whereby the charging service can be enhanced. .. Further, the charging trays 1A to 1D can be efficiently circulated and moved, and the time required for the movement can be shortened.

Further, the present invention is characterized in that the two tray-side current collecting terminals 13A and 13B are respectively arranged at diagonal positions on the left and right sides of the charging trays 1A to 1D in the approach direction of the electric vehicle.

According to such a configuration, even if the mechanical parking apparatus is provided with a turning device and the charging trays 1A to 1D are turned by the turning device, it depends on the orientation of the charging trays 1A to 1D. Without doing so, the tray side current collectors 13A and 13B can be opposed to the power supply terminals 12A and 12B.

Further, according to the present invention, the charging trays 1A to 1D are provided with two charging plug connecting portions electrically connected to the tray side current collecting terminals 13A and 13B and the charging cable, that is, charging outlets 14A and 14B.
