In addition, a control panel 16 that controls all of the mechanical parking device is installed on the floor 11, and controls each drive of the mechanical parking device 1.

[0032] [Elevator shaft] As shown in FIG. 3, the elevator 31 is installed in the elevator path 30 along the device height direction H between the lower part of the floor 3 of the loading / unloading room 2 and the pit 12 of the storage room 10. The elevator 31 includes an elevator frame 32, a lift body 36, and a drive unit 34 for raising and lowering the lift body 36. The lift body 36 is fixed to a chain wound around a pair of sprockets installed above and below (not shown), and can be raised and lowered by the rotation of the lower sprocket drivably fixed to the drive unit 34. The lift body 36 can stop at a position where the tray 18 can be delivered to the level of the multiple storage compartments 13 constructed in the storage room 10. In addition, a built-in turntable 38 described later is built into the upper part of the lift body 36, and the built-in turntable 38 can horizontally rotate the charging tray 18A or the non-charging tray 18D on the lift body 36.

[0033] Decks 20 are installed on both sides in the width direction W of the device of an opening portion of the floor 3 of the loading / unloading room 2, which is the boarding level. The decks 20 will be described in detail later.

[0034] [Entry and exit of non-charging trays] 4 shows a state in which the non-charging tray 18D is placed at the boarding level of the loading / unloading room 2. Decks 20 are installed at the openings 4 on both sides of the floor 3 in the width direction W of the device. The detailed structure of the deck 20 will be described later, but the deck 20 is configured to include a fixed deck 22 that is fixed horizontally at the boarding level from the opening 4 of the body 1A toward the non-charging tray 18D, and a movable deck 24 that is rotatably supported on the non-charging tray 18D side of the fixed deck 22.

[0035] The non-charging tray 18D is supported by a built-in turntable 38 provided on the upper part of the lift body 36. The movable deck 24 is raised so as to close the openings 4 on both sides in the short direction of the non-charging tray 18D. In this state, the vehicle 40 passes through the open entrance door 5 and enters the loading / unloading room 2, and stops on the non-charging tray 18D. The user gets off the stopped vehicle 40 and exits the loading / unloading room 2 through the entrance door 5.

[0036] [Receiving operation] The state of the non-charging tray 18D when entering the warehouse is shown in Fig. 4. As shown in Fig. 4, the non-charging tray 18D is placed at the boarding level. The movable deck 24 rotates to a horizontal state along the boarding level on both the left and right sides of the non-charging tray 18D in the device width direction W to block the opening 4. In this state, a non-charging vehicle 40 or a charging vehicle 40 that does not require charging enters the loading / unloading room 2 through the entrance / exit door 5. The user gets off the vehicle 40 and exits through the entrance / exit door 5, and closes the entrance / exit door 5 by operating the door close button provided on the operation panel 6. At this time, the user checks whether there is anyone in the loading / unloading room 2 and whether it is safe before operating the door close button.

[0037] FIG. 5 shows a state in which the non-charging tray 18D is lowered by the lifting device 31. First, when the tip of the rail on which the non-charging tray 18D of the lift body 36 is movably placed is folded inward in a direction along the longitudinal direction of the non-charging tray 18D, both sides of the movable deck 24 rotate downward and retreat from the elevator shaft 30. In this state, the lift body 36 descends the elevator shaft 30. Then, it is stored on the side of the storage compartment 13 of an appropriate layer in the storage room 10. In the case of the non-charging tray 18D, since there is no interference with the movable deck 24 during the lifting and lowering operation of the non-charging tray 18D, the lifting device 31 may be operated without rotating the movable deck 24. This is the state shown in FIG. 4, and even in this state, the lifting device can be lowered.

[0038] [Removal operation] FIG. 6 shows the state of the non-charging tray 18D when it leaves the warehouse. With both movable decks 24 rotating downward and retreating from the elevator 30, the lift body 36 rises to the loading / unloading room 2, and the lift body 36 stops when the non-charging tray 18D rises above the boarding level. At this point, the built-in turntable 38 rotates horizontally to change the direction of the vehicle 40 toward the entrance / exit door 5, and the lift body 36 descends to a position where the non-charging tray 18D matches the boarding level and stops. Then, although not shown, the tip of the rail on which the non-charging tray 18D of the lift body 36 is movably placed is folded inward in the direction along the longitudinal direction of the non-charging tray 18D, and the movable decks 24 on both sides rise to a position along the boarding level to close the opening 4, and the entrance / exit door 5 opens, and the user gets on the vehicle 40 and leaves the loading / unloading room 2. The state when it leaves the warehouse is the same as the state shown in FIG. 4. In the case of the non-charging tray 18D, the non-charging tray 18D that is landed in the loading / unloading room 2 may be raised above the boarding level and rotated by the built-in turntable 38, so that the orientation of the vehicle 40 is previously faced toward the entrance / exit door 5.

[0039] [Charging tray entry / exit: For electric vehicles with the charging port on the right side; first entry / exit position] 7 shows a state in which the charging tray 18A is landed at the boarding level with the wide portion 18B positioned on the opposite side of the lifting frame 32. This state occurs when an electric vehicle 40 is parked with its power supply port 42 on the right side in the width direction W of the device.

[0040] 7 and 8, in the loading / unloading room 2, a vehicle (electric vehicle) 40 is placed on the charging tray 18A with the power supply port 42 located on the right side, and a wide portion 18B is formed on the right side. An outlet 18C is installed in the wide portion 18B, and the outlet 18C is connected to the power supply port 42 of the electric vehicle 40 by a power supply cord 42B. At this time, charging is performed with the lid 42A of the power supply port 42 open, so that the wide portion 18B is formed on the charging tray 18A, and even when the power supply lid 42A of the power supply port 42 is opened 90 degrees relative to the side surface of the vehicle 40 as a tray eccentric to the right from the boarding center of the vehicle 40, it fits within the width dimension of the charging tray 18A.

[0041] At this time, the left side of the electric vehicle 40 of the movable deck 24 rises to close the opening 4, and the right side of the electric vehicle 40, i.e., the wide portion 18B side, rotates and is retracted from the elevator shaft 30.

[0042] [Receiving operation] 9 and 10, the charging tray 18A is stored on the right side of the vehicle 40 with the power supply cord 42B connected to the outlet 18C and the power supply port 42 and the power supply cover 42A open. At this time, the movable deck 24 located to the right of the charging tray 18A is rotated and remains withdrawn from the hoistway 30, and the movable deck 24 located to the left of the charging tray 18A is rotated and withdrawn from the hoistway 30. Then, the lift body 36 transports the charging tray 18A and the electric vehicle 40 placed thereon to the storage room 10.

[0043] [Removal operation] FIG. 11 shows a state in which the electric vehicle 40 is being pulled out with the charging tray 18A having the wide portion 18B on the right side. As shown in FIG. 11, the lift body 36 is loaded with a charging tray 18A with its wide portion 18B positioned on the right side of the electric vehicle 40, and is raised up the elevator shaft 30 to a position higher than the boarding level, i.e., to a position where the charging tray 18A can be rotated horizontally by the built-in turntable 38.

[0044] At this time, the tip of the rail on which the charging tray 18A of the lift body 36 is movably placed is folded inward in a direction along the longitudinal direction of the charging tray 18A, and both the left and right movable decks 24 rotate to a position where they are retracted from the elevator shaft 30. Although not shown, the charging tray 18A rotates 180 degrees toward the entrance door 5 by the built-in turntable 38, and the wide part 18B is positioned on the lift frame 32 side and descends to the boarding level. Then, the right movable deck 24 rises to close the opening 4. At this time, the tip of the rail on which the charging tray 18A of the lift body 36 is movably placed is folded inward in a direction along the longitudinal direction of the charging tray 18A so as not to interfere with the rotation of the movable deck 24.

[0045] [Charging tray entry / exit: For electric vehicles with the charging port on the left side; second entry / exit position] 12 shows a state in which the charging tray 18A is landed at the boarding level with the wide portion 18B positioned on the side of the lifting frame 32. This state occurs when an electric vehicle 40 is parked with its power supply port 42 on the left side in the width direction W of the device.

[0046] As shown in Figs. 12 and 13, in the loading / unloading room 2, a vehicle (electric vehicle) 40 is placed on a charging tray 18A with a power supply port 42 located on the left side, and a wide portion 18B is formed on the left side.

[0047] As shown in Fig. 2, the orientation of the charging trays 18A in the storage room 10 is unified so that the wide portions 18B are all on the right side. Therefore, in order to position the wide portions 18B on the left side of the electric vehicle 40, the charging tray 18A that has risen to the loading / unloading room 2 with the wide portions 18B on the right side (see Fig. 11) is raised above the boarding level and rotated 180 degrees by the built-in turntable 38 so that the wide portions 18B are positioned on the left side, and then the lift body 36 is lowered to land at the boarding level. When the charging tray 18A lands at the boarding level with the wide portions 18B positioned on the left side, the movable deck 24 located on the right side of the charging tray 18A rotates and rises to the boarding level to block the opening 4. Fig. 12 shows this state.

[0048] An outlet 18C is provided in the wide portion 18B, and the outlet 18C is connected to the power feed port 42 of the electric vehicle 40 by a power feed cord 42B. At this time, since charging is performed with the lid 42A of the power feed port 42 open, the charging tray 18A is formed with the wide portion 18B, and the tray is offset to the left from the boarding center of the vehicle 40, so that even when the power feed lid 42A of the power feed port 42 is opened 90 degrees relative to the side of the vehicle 40, it fits within the width dimension of the charging tray 18A.

[0049] [Receiving operation] 13 and 14 , the charging tray 18A is stored on the left side of the vehicle 40 with the power supply cord 42B connected to the outlet 18C and the power supply port 42 and the power supply lid 42A open. At this time, the movable deck 24 located to the left of the charging tray 18A is rotated and remains withdrawn from the hoistway 30, and the movable deck 24 located to the right of the charging tray 18A is rotated and withdrawn from the hoistway 30.

[0050] In the case of entering the storage, the empty charging tray 18A is landed at the boarding level, but as shown in Fig. 2, the empty charging tray 18A is located in the storage room 10 with the wide portion 18B formed on the right side of the charging tray 18A. In order to raise the charging tray 18A from this state to the storage / retrieval room 2 and land it at the boarding level, it is necessary to rotate the charging tray 18A 180 degrees by the built-in turntable 38 before landing it at the boarding level.

[0051] In this case, since the wide portion 18B of the charging tray 18A is located above the lifting frame 32 of the lifting device 31, the charging tray 18A cannot be lowered into the storage chamber 10 in this position. 14, the charging tray 18A rises above the boarding level due to the upward movement of the lift body 36. At that time, the rail on which the charging tray 18A of the lift body 36 is movably placed is folded inward at its tip end in the longitudinal direction of the charging tray 18A so as not to interfere with the rotation of the movable deck 24, and the right-side movable deck 24 is rotated to retract from the hoistway 30. In this state, the charging tray 18A rotates 180 degrees to position the wide portion 18B in a direction away from the lift frame 32, i.e., on the opposite right side.

[0052] FIG. 15 shows a state in which the charging tray 18A is lowered by the lifting device 31 with the wide portion 18B positioned on the opposite side of the lifting frame 32 after being rotated 180 degrees by the built-in turntable 38. As shown in FIG. 15, the charging tray 18A is lowered toward the storage chamber 10 by the lift body 36 with the wide portion 18B positioned to the right of the electric vehicle 40. At this time, the front side of the electric vehicle 40 faces the opposite side of the device depth direction D. In this manner, the lift body 36 transports the charging tray 18A and the electric vehicle 40 placed thereon to the storage chamber 10. FIG. 2 shows that some electric vehicles 40 are stored in the storage chamber 10 in a different orientation.

[0053] [Removal operation] A state in which the electric vehicle 40 is pulled out with the charging tray 18A having the wide portion 18B on the right side will be described with reference to FIG. 15, the charging tray 18A is loaded on the lift body 36 with the wide portion 18B positioned on the right side of the electric vehicle 40 and with the front side of the electric vehicle 40 facing the near side in the device depth direction D, and the lift body 36 ascends up the hoistway 30 to the loading / unloading room 2. At this time, both the left and right movable decks 24 rotate to a position where they are retracted from the hoistway 30. Here, although not shown, the charging tray 18A lands at the boarding level while remaining in this orientation, and the movable deck 24 on the lift frame 32 side rotates to close the opening 4 at the boarding level.

[0054] In this state, the entrance door 5 opens, and the user gets into the electric vehicle 40 and leaves the entrance / exit room 2. After leaving the parking lot, the user's confirmation operation and door closing operation are the same as in the case of an electric vehicle with the power supply port 42 on the right side.

[0055] Next, the configuration of the deck 20 will be described with reference to Figs. 16 and 17. As described above, the deck 20 is configured to include the fixed deck 22 fixed to the side of the body 1A, and the movable deck 24 rotatably provided on the side of the fixed deck 22 away from the opening 4. The movable deck 24 is rotatably provided on the fixed deck 22 by a support shaft 24A, and is connected to a bracket fixed to the lower surface side of the movable deck 24 by a link mechanism of a drive unit 26 fixed to a bracket 22B provided on the lower surface 22A side of the fixed deck 22. Specifically, the drive unit 26 may be a motor with a reducer, and a link 26D is provided rotatably via a shaft 26C on the free end side of an arm 26B fixed to the drive shaft 26A, and the free end side of the link 26D is connected to a bracket fixed to the lower surface side of the movable deck 24 by a driven shaft 24B. Fig. 16 shows the position where the opening 4 is blocked.

[0056] 17 shows a position in which the movable deck 24 has been rotated downward and withdrawn from the hoistway 30. FIG. 17, the arm 26B of the driving device 26 is driven counterclockwise as shown in the figure to drive the link 26D and rotate the movable deck 24. In this state, the movable deck 24 is retracted from the elevator shaft 30 and opens and closes the opening 4 without interfering with the charging tray 18A being raised and lowered.

[0057] Thus, in one embodiment of the present invention, regardless of the position of power feed port 42 provided on electric vehicle 40, wide portion 18B is provided on charging tray 18A, so that when power feed lid 42A of power feed port 42 is left open and power feed cord 42B is connected, it fits within the width dimension of charging tray 18A, and there is no need to adjust the parking position of electric vehicle 40 placed on charging tray 18A to the left or right.

[0058] As described above in detail, the mechanical parking device of the present invention is a mechanical parking device 1 having the loading / unloading room 2 and the storage room 10, which allow the electric vehicle 40 to load and unload the tray 18, the elevator 30 connecting the loading / unloading room 2 and the storage room 10, and the elevator frame 32 provided on one side in the width direction of the elevator 30, and at least a charging tray 18A having a wide portion 18B in which an outlet 18C is installed on one side in the width direction from the center where the electric vehicle 40 gets on, and when the power supply unit 42 of the electric vehicle 40 is located in the center in the width direction in the forward direction of the electric vehicle 40 or on the side opposite to the elevator frame 32, the charging tray 18A is provided with a wide portion 18B in which an outlet 18C is installed on one side in the width direction from the center where the electric vehicle 40 gets on, and and a second entrance / exit position where, when the power supply unit 42 of the electric vehicle 40 is located in the widthwise center in the forward direction of the electric vehicle 40 or on the side that is closest to the lifting frame 32, the charging tray 18 is rotated so that the wide portion 18B of the charging tray 18A is positioned on the side of the lifting frame 32, and the electric vehicle 40 enters / exits at a position excluding the wide portion 18B. The charging tray 18A is positioned at the second entrance / exit position, and is rotated so that the wide portion 18B is positioned on the opposite side of the lifting frame 32 after entering the parking lot.

[0059] As a result, by positioning the wide portion 18B in advance on the side of the power feed port 42 in accordance with the position of the power feed port 42 on the electric vehicle 40, the electric vehicle 40 to be powered can be charged in a state where it fits within the width dimension of the charging tray 18A with the power feed lid 42A of the power feed port 42 open.

[0060] Further, the wide portion 18B has a dimension that includes the dimension of the power supply cover 42A of the power supply unit 42 in the electric vehicle 40 in an open state or the dimension of the protruding power supply cord 42B including the power supply plug.

[0061] This allows the protrusion of power supply cover 42A of power supply port 42 or power supply cord 42B including the power supply plug to be accommodated within the dimensions of wide portion 18B.

[0062] In addition, an opening 4 is provided in the floor 3 of the loading / unloading room 2, and movable decks 24 that can be opened and closed are provided on both widthwise sides of the tray 18 of the opening 4, and when the charging tray 18A is landed in the loading / unloading room 2, the movable deck 24 on the wide portion 18B side is set to a retracted position where it is retracted from the elevator shaft 30.

[0063] This allows the opening 4 in the floor 3 of the loading / unloading room 2 to be blocked even when the charging tray 18A having the wide portion 18B on one side of the width direction is rotated or the non-charging tray 18D is landed at the boarding level, allowing users to walk safely.

[0064] In addition, when the tray 18 including the charging tray 18A moves up and down the elevator shaft 30, the movable deck 24 can be retracted from the elevator shaft 30 on both sides of the width of the tray 18.

[0065] This makes it possible to avoid mutual interference in a small gap between the tray 18 including the charging tray 18A and the movable deck 24 even if the tray 18 swings when being raised or lowered.

[0066] The movable deck 24 is rotatably fixed to the fixed deck 22 which is fixed to the opening 4, and is rotated by a drive device 26 between a blocking position where the movable deck 24 blocks the opening 4 and a retracted position where the movable deck 24 is retracted from the elevator shaft 30.

[0067] As a result, by forming a wide opening 4, the structural area of ​​the floor 3 of the loading / unloading room 2 is reduced, thereby reducing the cost of construction work, and the drive device 26 makes it possible to rotate at an accurate position.

[0068] Further, a plurality of storage compartments 13 are formed in the storage chamber 10, and the storage compartments 13 include charging storage compartments 13A in which charging trays 18A having wide portions 18B face in the same direction.

[0069] As a result, the charging tray 18A stored in the storage chamber 10 can be faced in the same direction relative to the loading / unloading room 2, where the orientation of the charging tray 18A changes, so that the power supply on the storage chamber 10 side relative to the current collector of the charging tray 18A can be installed in the same direction, which contributes to cost reduction.

[0070] Further, the storage compartment 10 has a charging storage compartment 13A disposed on the side closer to the lifting device 31, and a non-charging storage compartment 13B disposed on the side farther from the lifting device 31 than the charging storage compartment 13A.

[0071] As a result, the non-charging tray 18D, which does not have a wide portion 18B, passes over the wide charging storage compartment 13A in which the charging tray 18A having the wide portion 18B is stored, and is stored on the side farther from the lifting device 31, so there is no need to create wasted space in the arrangement of the storage compartment 13 within the storage room 10.

[0072] Although one embodiment of the present invention has been disclosed above, the present invention is not limited thereto, and it goes without saying that other aspects, modifications, or improvements of the present invention are included within the technical scope of the present invention.
