[0027] Furthermore, in this embodiment, vehicle 40 means both non-charged vehicles and electric vehicles, and these terms may be used interchangeably. Here, non-charged vehicles include general gasoline vehicles that do not have a drive battery, and electric vehicles that do not require charging upon arrival at the depot. Electric vehicles include not only electric vehicles (EVs, BEVs, etc.), but also rechargeable vehicles such as plug-in hybrid vehicles (PHVs, PHEVs, etc.) that combine an internal combustion engine such as a gasoline engine with a drive motor.

[0028] [Embodiment] <Overall configuration of the mechanical parking system> Figure 1 shows an example of the mechanical parking system of the present invention. As shown in Figures 1 to 3, the mechanical parking system 1 has an entry / exit compartment 2, a storage compartment 10, and a lift passage 30 connecting the entry / exit compartment 2 and the storage compartment 10.

[0029] [Warehouse / Inbound / Outbound Room] As shown in Figure 1, the loading / unloading room 2 is formed in part of building 1A, and in this embodiment, building 1A is made up of a structural frame. The loading / unloading room 2 is provided with a floor 3 in which an opening 4 is formed. The upper surface of the floor 3 is at the same level as the loading level into which the vehicle 40 enters the tray 18 (charging tray 18A or non-charging tray 18D). An entrance / exit door 5 is provided in part of the wall in the direction in which the vehicle 40 moves in and out of the loading / unloading room 2, and an operation panel 6 for users to operate loading / unloading is installed next to the entrance / exit door 5. A deck 20, which will be described later, is installed in the opening 4.

[0030] [Hanging Room] As shown in Figures 2 and 3, the storage room 10 is formed of a frame 1A and has a floor 11. Multiple storage compartments 13 are formed around the elevator shaft 30, supported by rails 14A on which frames 14 and trays 18 are movably mounted. In this embodiment, multiple charging storage compartments 13A are set in an area close to the elevator shaft 30, and multiple non-charging compartments 13B are set in an area far from the elevator shaft 30. Multiple charging trays 18A are arranged in the charging storage compartments 13A, and multiple non-charging trays 18D are arranged in the non-charging compartments 13B.

[0031] The storage compartment 13 as a whole has multiple empty compartments, which serve as destinations for the circulating movement of the charging tray 18A or non-charging tray 18D. Each storage compartment 13 is also equipped with a vertical and horizontal drive device 15 that moves the charging tray 18A or non-charging tray 18D in the device width direction W or the device depth direction D, i.e., vertical and horizontal movement in a plan view. A pit 12 is formed in the elevator shaft 30, which is lowered from the floor 11, and a lifting device 31, which will be described later, is installed there. Although not shown, the charging storage compartment is equipped with an electron supply device at a position corresponding to the electron collector of the charging tray 18A, and this is located in the same position in all charging storage compartments. In this embodiment, the electron supply device is located approximately in the center of the device depth direction D and to the right in the device width direction W of the charging storage compartment 13A. A control panel 16 that controls all aspects of the mechanical parking system is installed on the floor 11 and controls each drive of the mechanical parking system 1.

[0032] [Elevator] As shown in Figure 3, a lifting device 31 is installed in the elevator shaft 30 between the floor 3 of the loading / unloading room 2 and the pit 12 of the storage room 10, along the height direction H of the device. The lifting device 31 consists of a lifting frame 32, a lift body 36, and a drive unit 34 that raises and lowers the lift body 36. The lift body 36 is fixed to a chain that is wrapped around a pair of sprockets (not shown) installed above and below, and is raised and lowered by the rotation of the lower sprocket which is fixed to the drive unit 34 in a drivable manner. This lift body 36 can stop at a position in which the trays 18 can be transferred to the levels of the multiple storage compartments 13 constructed in the storage room 10. In addition, a built-in turntable 38, which will be described later, is incorporated into the upper part of the lift body 36, and the built-in turntable 38 is capable of horizontally rotating the charging tray 18A or non-charging tray 18D on the lift body 36.

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

[0034] [Inbound and outbound of non-charging trays] Figure 4 shows the state in which the non-charging tray 18D is resting on the loading level of the loading / unloading room 2. Decks 20 are installed in the openings 4 on both sides of the floor 3 in the device width direction W. The detailed structure of the deck 20 will be described later, but the deck 20 is composed of a fixed deck 22 that is fixed horizontally to the loading level from the opening 4 of the main 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 located on top of the lift body 36. The movable deck 24 is raised so as to block the openings 4 on both sides of the non-charging tray 18D in the short direction. In this state, the vehicle 40 enters the loading / unloading room 2 through the open entrance / exit door 5 and stops on the non-charging tray 18D. The passenger disembarks from the stopped vehicle 40 and exits the loading / unloading room 2 through the entrance / exit door 5.

[0036] [Receiving operation] Figure 4 shows the state of the non-charging tray 18D upon entry. As shown in Figure 4, the non-charging tray 18D is resting on the boarding level. The movable deck 24 rotates horizontally along the boarding level on both the left and right sides in the device width direction W of the non-charging tray 18D, closing the opening 4. In this state, a non-charging vehicle 40 or a charging vehicle 40 that does not require charging enters the entry / exit room 2 through the entrance / exit door 5. The user disembarks from the vehicle 40, exits through the entrance / exit door 5, and closes the entrance / exit door 5 by operating the door close button provided on the control panel 6. At this time, the user confirms that the entry / exit room 2 is unoccupied and checks for safety before operating the door close button.

[0037] Figure 5 shows the state in which the non-charging tray 18D is being lowered by the lifting device 31. First, when the end of the rail on which the non-charging tray 18D is movably mounted on the lift body 36 is folded inward along the longitudinal direction of the non-charging tray 18D, the movable deck 24 rotates downward on both sides and retracts from the hoistway 30. In this state, the lift body 36 descends the hoistway 30. It is then stored on the side of the storage compartment 13 at the appropriate level in the storage room 10. In the case of the non-charging tray 18D, there is no interference with the movable deck 24 during the lifting operation of the non-charging tray 18D, so the lifting device 31 may be operated without rotating the movable deck 24. This is the state shown in Figure 4, and the lifting device can still be lowered in this state as well.

[0038] [Delivery operation] Figure 6 shows the state of the non-charging tray 18D when it is being released. With both movable decks 24 rotated downward and retracted from the elevator shaft 30, the lift body 36 rises into the loading / unloading room 2, and the lift body 36 stops when the non-charging tray 18D has risen above the boarding level. At this point, the built-in turntable 38 rotates horizontally to change the orientation of the vehicle 40 toward the entrance / unloading door 5, and the lift body 36 lowers and stops when the non-charging tray 18D is at the boarding level. Then, although not shown in the figure, the end of the rail on which the non-charging tray 18D is movably placed on the lift body 36 folds inward along the longitudinal direction of the non-charging tray 18D, the movable decks 24 on both sides rise to a position aligned with the boarding level and close the opening 4, and the entrance / unloading door 5 opens, allowing the user to board the vehicle 40 and exit the loading / unloading room 2. The state when the vehicle is being released is the same as the state shown in Figure 4. In the case of a non-charging tray 18D, the non-charging tray 18D, which is resting in the loading / unloading compartment 2, may be raised above the loading level by the built-in turntable 38 and rotated so that the vehicle 40 is facing the entrance / exit door 5 in advance.

[0039] [Charging tray entry / exit: For electric vehicles with the power supply port on the right side; first entry / exit position] Figure 7 shows the state in which the charging tray 18A is positioned with its wide section 18B on the opposite side of the lifting frame 32 and is resting on the boarding level. This state occurs when an electric vehicle 40 is being brought into storage with its power supply port 42 located on the right side in the device width direction W.

[0040] As shown in Figures 7 and 8, in the loading / unloading compartment 2, the charging tray 18A is designed to accommodate a vehicle (electric vehicle) 40 with its power supply port 42 located on the right side, and a wide section 18B is formed on the right side. An outlet 18C is installed in the wide section 18B, and the outlet 18C and the power supply port 42 of the electric vehicle 40 are connected by a power cord 42B. At this time, charging is performed with the cover 42A of the power supply port 42 open, so the charging tray 18A has a wide section 18B, and even when the power supply cover 42A of the power supply 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, as a tray that is eccentrically positioned to the right from the center of entry of the vehicle 40.

[0041] At this time, the movable deck 24 is in a state where the left side of the electric vehicle 40 rises to close the opening 4, and the right side of the electric vehicle 40, that is, the side with the wide section 18B, rotates and is retracted from the elevator shaft 30.

[0042] [Receiving operation] As shown in Figures 9 and 10, the charging tray 18A is placed in the storage area with the power supply cord 42B connected to the outlet 18C and power supply port 42 on the right side of the vehicle 40, and the power supply cover 42A remaining open. At this time, the movable deck 24 located to the right of the charging tray 18A is rotated and retracted from the elevator shaft 30, while the movable deck 24 located to the left of the charging tray 18A is rotated and retracted from the elevator shaft 30. Then, the lift body 36 transports the charging tray 18A and the electric vehicle 40 placed on it to the storage room 10.

[0043] [Delivery operation] Figure 11 shows the state in which the electric vehicle 40 is being taken out of the charging tray 18A with the wide section 18B on the right side. As shown in Figure 11, the charging tray 18A is mounted on the lift body 36 with the wide section 18B positioned to the right of the electric vehicle 40, and the lift is raised in the hoistway 30 to a position higher than the boarding level, that is, to a position where the charging tray 18A can rotate 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 mounted is folded inward along the longitudinal direction of the charging tray 18A, and the movable deck 24 is in a position where both the left and right sides are rotated to retract from the elevator shaft 30. Here, although not shown in the figure, the charging tray 18A rotates 180 degrees toward the entrance door 5 by the built-in turntable 38, and the wide section 18B is positioned toward the lifting frame 32, and it descends to the boarding level. Then the right movable deck 24 rises and closes the opening 4. At this time, the tip of the rail on which the charging tray 18A of the lift body 36 is movably mounted is folded inward 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 power supply port on the left side; second entry / exit position] Figure 12 shows the state in which the charging tray 18A is positioned with its wide section 18B on the side of the lifting frame 32 and is resting on the boarding level. This state occurs when an electric vehicle 40 is being brought into storage with its power supply port 42 located on the left side in the device width direction W.

[0046] As shown in Figures 12 and 13, in the loading / unloading compartment 2, the charging tray 18A is used to place a vehicle (electric vehicle) 40 with the power supply port 42 located on the left side, and a wide section 18B is formed to the left of this vehicle.

[0047] As shown in Figure 2, the orientation of the charging trays 18A in the storage compartment 10 is standardized so that the wide section 18B is always on the right side. Therefore, in order to position the wide section 18B on the left side of the electric vehicle 40, the charging tray 18A, which has been raised into the loading / unloading compartment 2 with the wide section 18B on the right side (see Figure 11), is raised above the loading level and rotated 180 degrees by the built-in turntable 38 so that the wide section 18B is on the left side, and then the lift body 36 descends to land on the loading level. When the charging tray 18A lands on the loading level with the wide section 18B on the left side, the movable deck 24 located to the right of the charging tray 18A rotates and rises to the loading level to close the opening 4. Figure 12 shows this state.

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

[0049] [Receiving operation] As shown in Figures 13 and 14, the charging tray 18A is placed in the vehicle 40 with the power supply cord 42B connected to the outlet 18C and the power supply port 42 on the left side of the vehicle 40, and the power supply cover 42A remains open. At this time, the movable deck 24 located to the left of the charging tray 18A is rotated and retracted from the elevator shaft 30, while the movable deck 24 located to the right of the charging tray 18A is rotated and retracted from the elevator shaft 30.

[0050] When a vehicle is being brought into storage, an empty charging tray 18A is brought down to the loading level. However, as shown in Figure 2, in the storage chamber 10, the wide section 18B of the empty charging tray 18A is positioned to the right of the charging tray 18A. In order to raise the charging tray 18A into the loading / unloading chamber 2 from this position and bring it down to the loading level, it is necessary to rotate it 180 degrees using the built-in turntable 38 before bringing it down to the loading level.

[0051] In this case, the wide portion 18B of the charging tray 18A is located above the lifting frame 32 of the lifting device 31, so the charging tray 18A cannot be lowered into the storage chamber 10 in this position. Therefore, as shown in Figure 14, the charging tray 18A rises above the boarding level due to the upward movement of the lift body 36. At this time, the rail on which the charging tray 18A is movably mounted on the lift body 36 is folded inward in advance at its leading edge 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, and the right side of the movable deck 24 is rotated to a position away from the elevator shaft 30. In this state, the charging tray 18A rotates 180 degrees, and the wide section 18B is positioned away from the lifting frame 32, that is, on the opposite right side.

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

[0053] [Delivery operation] Figure 15 illustrates the state in which the electric vehicle 40 is released from the charging tray 18A with the wide section 18B on the right side. As shown in Figure 15, the charging tray 18A is mounted on the lift body 36 with the wide section 18B positioned to the right of the electric vehicle 40, and the front of the electric vehicle 40 facing the front side in the depth direction D of the device, and the lift rises up the elevator shaft 30 into the loading / unloading room 2. At this time, both the left and right movable decks 24 are rotated to a position where they are retracted from the elevator shaft 30. Here, although not shown, the charging tray 18A lands on the loading level in this orientation, and the movable decks 24 on the side of the lifting frame 32 rotate to close the opening 4 at the loading level.

[0054] In this state, the entrance / exit door 5 opens, and the user boards the electric vehicle 40 and exits the storage room 2. The user verification process and door closing operation after exiting 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 explained with reference to Figures 16 and 17. As described above, the deck 20 is composed of a fixed deck 22 fixed to the side of the main body 1A and a 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 to 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 device 26 fixed to a bracket 22B provided on the lower surface 22A side of the fixed deck 22. Specifically, the drive device 26 may use a motor with a reduction gear, and a link 26D is rotatably provided on the free end side of an arm 26B fixed to the drive shaft 26A via a shaft 26C, 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. Figure 16 shows the position that closes the opening 4.

[0056] Figure 17 shows the position where the movable deck 24 has been rotated downward and moved out of the elevator shaft 30. As shown in Figure 17, the arm 26B of the drive unit 26 is driven counterclockwise as shown in the figure, which drives the link 26D and causes the movable deck 24 to rotate. 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 that is raised and lowered.

[0057] Thus, in one embodiment of the present invention, regardless of the position of the power supply port 42 provided on the electric vehicle 40, the wide portion 18B is provided on the charging tray 18A so that the power supply cord 42B can be connected with the power supply cover 42A of the power supply port 42 open and still fit within the width dimension of the charging tray 18A. Therefore, there is no need to adjust the parking position of the electric vehicle 40 placed on the charging tray 18A to the left or right.

[0058] As described in detail above, the mechanical parking system of the present invention comprises an entry / exit compartment 2 and a storage compartment 10, through which an electric vehicle 40 can enter and exit the tray 18, and a connecting element between the entry / exit compartment 2 and the storage compartment 10. A lifting device 31 was installed. A mechanical parking device 1 having an elevator shaft 30 and an elevator frame 32 provided on one side in the width direction of the elevator shaft 30, wherein it has at least a charging tray 18A having a wide section 18B on one side in the width direction from the center into which an electric vehicle 40 enters, on which an outlet 18C is installed. Entering and exiting storage room 2 Power supply for electric vehicle 40 mouth 42 The electricity If the vehicle 40 is located on the side opposite to the lifting frame 32 in the forward direction, Charging tray 18A, The wide section 18B of the charging tray 18A is located on the opposite side of the lifting frame 32. It is placed in the first loading / unloading position, The electric vehicle 40 enters and exits the depot in a position excluding the wide section 18B. So , Meanwhile, goods enter and exit storage room 2. Power supply for electric vehicle 40 mouth 42 The electricity If the vehicle 40 is positioned on the side of the lifting frame 32 in the forward direction, The charging tray 40, The charging tray 18A is rotated so that the wide portion 18B of the charging tray 18A is positioned on the side of the lifting frame 32. It is placed in the second loading / unloading position, The electric vehicle 40 enters and exits the depot in a position excluding the wide section 18B. So The charging tray 18A, which is the second loading / unloading position, 40 electric vehicles After entering the garage, rotate the wide section 18B so that it is on the opposite side of the lifting frame 32.

[0059] As a result, by positioning the wide section 18B in advance on the side of the power supply port 42 in accordance with the position of the power supply port 42 on the electric vehicle 40, the electric vehicle 40 can be charged while the power supply cover 42A of the power supply port 42 is open, so that it fits within the width dimension of the charging tray 18A.

[0060] Furthermore, the wide section 18B is used for power supply in the electric vehicle 40. mouth The dimensions of the power supply cover 42A of 42 include the dimensions of the open state or the protruding dimensions of the power supply cord 42B including the power supply plug.

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

[0062] Furthermore, the floor 3 of the loading / unloading room 2 has an opening 4, and movable decks 24 that can be opened and closed are provided on both sides of the width direction of the tray 18 in the opening 4. When the charging tray 18A is in contact with the loading / unloading room 2, the movable deck 24 on the side of the wide section 18B is set to a retracted position, moving away from the elevator shaft 30.

[0063] As a result, even when the charging tray 18A, which has a wide section 18B on one side in the width direction, is rotated, or when the non-charging tray 18D is on the loading level, the opening 4 in the floor 3 of the loading / unloading room 2 can be closed, allowing users to walk safely.

[0064] Furthermore, 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 in the width direction of the tray 18.

[0065] This allows the tray 18, including the charging tray 18A, and the movable deck 24 to avoid interference with each other even when the tray 18 shakes during its raising and lowering motion, due to the small gap between them.

[0066] Furthermore, the movable deck 24 is rotatably fixed to the fixed deck 22 which is fixed to the opening 4, and is rotated by the drive device 26 between a closed position that closes the opening 4 and a retracted position that moves away from the elevator shaft 30.

[0067] This reduces the structural area of ​​the floor 3 of the loading / unloading room 2 by forming a wide opening 4, thereby lowering construction costs, and also enables rotation at a precise position by the drive device 26.

[0068] Furthermore, the storage chamber 10 is formed with multiple storage compartments 13, and each storage compartment 13 has a charging tray 18A with a wide section 18B. With respect to the lifting device 31 It has charging and storage compartments 13A facing the same direction.

[0069] This allows the charging tray 18A to be stored in the storage compartment 10, while the orientation of the charging tray 18A changes in the loading / unloading compartment 2. With respect to the lifting device 31 Because they are oriented in the same direction, the electron supply from the storage chamber 10 to the electron collector of the charging tray 18A can be unified and installed in the same direction, which can contribute to cost reduction.

[0070] Furthermore, the storage compartment 10 has a charging storage compartment 13A located on the side closer to the lifting device 31, and a non-charging storage compartment 13B on the side of the charging storage compartment 13A that is further away from the lifting device 31.

[0071] As a result, the non-charging tray 18D, which does not have a wide section 18B, passes over the wide charging storage compartment 13A where the charging tray 18A, which has a wide section 18B, is stored on the side furthest from the lifting device 31, thus eliminating the need to create wasted space in the arrangement of the storage compartments 13 within the storage chamber 10.

[0072] Although one embodiment of the present invention has been disclosed above, the present invention is not limited thereto, and of course, other aspects, modifications, or improvements of the present invention are included in the technical scope. [Explanation of symbols]
