Description

Technical Field

[0001] The present invention relates to a mechanical parking device with a charging function for an EV vehicle.

Background Art

[0002] In recent years, instead of general gasoline vehicles, EV vehicles (electric vehicles) powered by electric motors have become widespread. Although EV vehicles are excellent for environmental protection because they can reduce exhaust gas emissions, they need to charge the battery instead of refueling with gasoline. Therefore, a mechanical parking device with a charging function that charges an EV vehicle using the time stored in the mechanical parking device has been developed. In such a mechanical parking device with a charging function, for example, a charging stand for power supply is provided on a pallet on which an EV vehicle is mounted. At the time of storage, the user himself / herself connects the charging stand and the EV vehicle with a charging cable. The pallet is stored in the storage space of the mechanical parking device until it is taken out while the EV vehicle is connected to the charging stand. Such a mechanical parking device is disclosed in, for example, Patent Document 1. The mechanical parking device disclosed in Patent Document 1 includes a collapsible charging stand on a pallet to which a charging plug connection part is attached at a position that becomes the upper side when erected. The user of the mechanical parking device erects the charging stand at the time of charging and folds the charging stand when it is not needed. The mechanical parking device of Patent Document 1 provides guidance regarding the storage of the charging facility by voice guidance by a speaker, image guidance using a guidance monitor installed near the entrance / exit, and lighting of a warning lamp when the erected state of the charging stand is detected by a detection device.

Summary of the Invention

Problems to be Solved by the Invention

[0004] As mentioned above, in the mechanical parking system described in Patent Document 1, the user of the mechanical parking system is responsible for storing the charging stand. However, as long as the action of "storing the charging stand" is performed by a human, "forgetting to put away the charging stand" will inevitably occur, no matter how much the machine tries to remind the user. As a result, the next user who wants to use a pallet with the charging stand left extended has to perform an extra step before they can park their own vehicle: "get out of the car, enter the parking area, lower the charging stand, return to the parking area, and then get back into the car." This reduces user convenience and the speed of parking. This extra step is a significant burden, especially for wheelchair users and users with disabilities, when parking. Therefore, the possibility of such a situation occurring in mechanical parking systems with charging functions should have been eliminated.

[0005] On the other hand, if the raising and lowering of the charging station is left to the automatic control of the mechanical parking system, there is a possibility that the mechanical parking system may start lowering the charging station even if the user has not yet disconnected the charging cable from the charging station and the EV vehicle. To avoid this, human judgment must always be involved in lowering the charging station. Therefore, in order to operate a mechanical parking system with a charging function conveniently and safely, it was necessary to create a system that would ensure a person retracts the charging stand when exiting the parking space.

[0006] This invention was devised to solve the problems described above. In other words, the objective of this invention is to provide a mechanical parking device with a charging function that reliably retracts the charging stand when the vehicle is exited. [Means for solving the problem]

[0007] According to the present invention, a pallet on which an EV vehicle is mounted on the top surface, A charging stand that can supply power to the EV vehicle in a protruding position that extends above the upper surface of the pallet, and that can deform between the protruding position and a stored position that is stored below the height of the upper surface, A passenger compartment where the aforementioned pallet is installed, A traffic obstruction device that protrudes inward from the exit path through which the EV vehicle passes when it exits the parking lot, thereby obstructing the passage of the EV vehicle, The system includes a control device that controls the operation of the aforementioned traffic obstruction device, The control device provides a mechanical parking system with a charging function, which extends the traffic obstruction device inward into the exit path when the charging stand is in the protruding position, and retracts the traffic obstruction device outward into the exit path when it is determined that the charging stand is in the retracted position. [Effects of the Invention]

[0008] According to the present invention described above, while the charging stand is in a protruding position when exiting the parking area, the traffic obstruction device protrudes inward from the exit path to block the passage of EV vehicles, and after it is confirmed that the charging stand is in a retracted position, the traffic obstruction device retracts to the outside of the exit path. As a result, the mechanical parking system with charging function of the present invention can reliably retract the charging stand when users who have used the charging stand exit the parking area.

Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described based on the drawings. In each figure, the same reference numerals are given to the common parts, and duplicate explanations are omitted.

[0011] FIG. 1 is a front view showing an example of the mechanical parking device 10. In this example, the mechanical parking system 10 is an elevator parking system. In this diagram, 1 is the EV vehicle, 2 is the elevator shaft, 3 is the pallet on which the EV vehicle 1 is placed while charging, 4 is the storage rack, 6 is the cage that moves along the elevator shaft 2, 8 is the main frame, 9 is the passenger compartment for the EV vehicle 1 to enter and exit, and 12 is the traction-type (friction-driven) hoisting machine installed on top of the main frame 8.

[0012] In this example, cage 6 moves up and down the elevator shaft 2 carrying pallets 3. Storage racks 4 are arranged along the elevator shaft 2 and each stores a pallet 3.

[0013] Furthermore, the mechanical parking system 10 of the present invention is not limited to elevator parking, but may be any other mechanical parking system, such as a vertical circulation parking system, a horizontal circulation parking system, or a planar reciprocating parking system, as long as it includes a pallet 3 and an entrance / exit room 9. Furthermore, while pallet 3 is a flat pallet in this example, the present invention is not limited to this, and may also be a folded pallet, a skewer-type cage, or a conveyor device.

[0014] Figure 2 is a view taken along arrow AA in Figure 1. This figure shows a plan view of passenger compartment 9. In this figure, the mechanical parking system 10 includes an entry / exit compartment 9, a pallet 3 installed at the entry point of the entry / exit compartment 9, a charging station 5 for supplying power to the EV vehicle 1 on the pallet, a monitoring device 7 for the charging station 5, a traffic blocking device 11, and a control device 13.

[0015] A pallet 3 is installed in the center of the passenger compartment 9 in this diagram. The mechanical parking system 10 is configured so that users or the administrator of the mechanical parking system 10 (hereinafter referred to as "users, etc.") can park their EV vehicles 1 by driving them themselves and loading them onto the upper surface 3a of the pallet 3. An electrically operated opening and closing door 9b is provided at the passageway 9a of the passenger compartment 9. The passageway 9a is the entrance and exit of the passenger compartment 9 through which the EV vehicle 1 passes when leaving the parking system.

[0016] The pallet 3 is equipped with a charging stand 5 for supplying power to the mounted EV vehicle 1. The charging stand 5 is designed to be deformable between a protruding position, where it extends above the upper surface 3a of the pallet 3 when power is supplied, and a retracted position, where it is stored at or below the height of the upper surface 3a of the pallet 3 (i.e., flush with or below the upper surface 3a of the pallet 3). For example, the charging stand 5 in Figure 2 is rotatable at its base and swings between the protruding and retracted positions. In this example, a storage chamber 5b for storing the charging stand 5 is open on the upper surface 3a of the pallet 3, and the charging stand 5 is stored below the upper surface of the pallet 3 by tilting it into the storage chamber 5b. The method by which the charging stand 5 moves between the extended and retracted positions is not limited to the swinging motion described above. For example, the charging stand 5 may change its position between the extended and retracted positions by extending or retracting. Users can change the position of the charging stand 5 manually.

[0017] The monitoring device 7 monitors whether the charging stand 5 is in an extended position or a retracted position. The monitoring device 7 is a device that detects whether the charging stand 5 is protruding above the upper surface 3a of the pallet 3. For example, a sensor for detecting people or a sensor for detecting vehicle position that is originally attached to the mechanical parking system 10 may be used as the monitoring device 7. In this case, for example, the posture of the charging stand 5 is detected simultaneously with the presence or absence of people and the position of vehicles.

[0018] For example, the monitoring device 7 may be a 3DLiDAR 7a that detects the position of the vehicle and people along with the orientation of the charging station 5. Alternatively, the monitoring device 7 may be a photoelectric sensor 7b that detects the charging station 5 in a protruding position, as shown in Figure 2. Alternatively, the monitoring device 7 may be a proximity sensor 7c. If the monitoring device 7 is a proximity sensor 7c, as shown in Figure 2, the proximity sensor 7c that detects the charging station 5 may be installed inside the storage compartment 5b, or the proximity sensor 7c that detects the inner wall of the storage compartment 5b may be installed on the charging station 5.

[0019] A traffic blocking device 11 is installed in the exit route R through which the EV vehicle 1 passes when exiting the parking lot. For example, the exit route R is a virtual three-dimensional space that is the area through which the body of the EV vehicle 1 may pass when exiting the parking lot. In this case, the area below the floor height of the passenger compartment 9 corresponds to the "outside of the exit route R." This is because, regardless of the type of car parked, the tires will not reach below the floor height. Also, at least the space above the height of the passageway 9a corresponds to the "outside of the exit route R." This is because only cars with a roof height lower than the height of the passageway 9a can enter the passenger compartment 9. On the other hand, the "inside of the exit route R" corresponds to a virtual space that is in front of the front of the EV vehicle 1 on the pallet placed in the entry area, and lower than the height of the passageway 9a.

[0020] Furthermore, the mechanical parking system 10 is equipped with a control device 13. The control device 13 controls the operation of the entire mechanical parking system 10, including the opening and closing of the opening and closing doors 9b, the driving of the traffic obstruction device 11, the transport of the pallet 3, and detection by the monitoring device 7.

[0021] Specific embodiments of the present invention will be described below. (First Embodiment) Figure 3 is a perspective view of the passenger compartment 9 in the first embodiment of the present invention. Figure 3(A) shows the charging station 5 before it is retracted when the vehicle is being taken out of the parking lot, and Figure 3(B) shows the charging station 5 after it is being retracted when the vehicle is being taken out of the parking lot. When the door 9b opens upon departure, the pallet 3 carrying the EV vehicle 1 to be departed is placed in the passenger compartment 9. At this point, the charging stand 5 is still upright (protruding), and the charging stand 5 and the EV vehicle 1 are connected by a charging cable 5a.

[0022] The passage-blocking device 11 in this embodiment is installed between the front end 3b of the pallet 3 installed in the passenger compartment 9 and the passageway 9a, and is extendable and retractable between a visibility height H that can be seen by users from the driver's seat of the EV vehicle 1 and the floor height F of the passenger compartment 9. A retraction hole 11a for housing the passage-blocking device 11 is provided in the floor 9c between the front end 3b of the pallet 3 installed in the passenger compartment 9 and the passageway 9a. As shown in Figure 3(A), when the charging station 5 is in a protruding position when exiting the parking lot, the passage-blocking device 11 extends from the retraction hole 11a to the visibility height H, blocking the passage of the EV vehicle 1. Users can enter the passenger compartment 9 from the passageway 9a and proceed to the EV vehicle 1 by passing beside the passage-blocking device 11.

[0023] In addition, in this example, a display board 14 is provided on the upper end of the traffic obstruction device 11 and on the wall above the passageway 9a, so that it can be seen by users from the driver's seat of the EV vehicle 1. This display board 14 displays instructions to encourage users to retract the charging stand 5. For example, the display board 14 may be an electronic display board that alternately displays the words "Please retract the charging stand" and "Please put it away". This makes it possible to clearly inform users that the reason the traffic obstruction device 11 is not lowering is because "the charging stand 5 has not been retracted". Note that the display board 14 may be located both near the passageway 9a and on the upper end of the traffic obstruction device 11, or it may be provided on only one of them. Furthermore, the mechanical parking system 10 may be equipped with a speaker and use voice guidance to prompt users to store the charging station 5.

[0024] (First embodiment of the traffic obstruction device 11) Figure 4 is an explanatory diagram of the first embodiment of the traffic obstruction device 11 in the mechanical parking system 10 of the first embodiment. Figure 4(A) is a view taken along the arrow JJ in Figure 3(B). Figure 4(B) is a view taken along the arrow KK in Figure 3(A). The traffic obstruction device 11 of this embodiment includes a barrier 11g that stands in the way of the exit route R, and an actuator 11h that moves the barrier 11g between the inside and outside of the exit route R.

[0025] The passage-blocking device 11 is installed in a retraction hole 11a opened in the floor 9c of the passenger compartment 9, and extends and retracts between the visibility height H and the floor height F. For example, the operating device 11h may have a pantograph 11b and an actuator 11c, as shown in this figure. The actuator 11c may be, for example, a rack and pinion or a hydraulic syringe. The upper end of the blocking part 11g is covered with a hard case 11d so that it does not fall into the retraction hole 11a even if a user steps on it when it is retracted. When the passage-blocking device 11 is retracted, the upper surface of this case 11d becomes flush with the floor 9c of the passenger compartment 9, closing the retraction hole 11a. This allows users to safely walk around the passenger compartment 9. The drive of the actuator 11c is controlled by the control device 13 of the mechanical parking device 10.

[0026] Furthermore, it is preferable that the pantograph 11b of the traffic obstruction device 11 in this embodiment is covered by a cover 11e made of a sheet-like material. This cover 11e may be, for example, a corrugated resin or cloth. This prevents users from coming into contact with the pantograph 11b, thereby preventing accidents such as fingers getting caught.

[0027] The extension / retraction mechanism of the traffic obstruction device 11 in this embodiment does not have to be a pantograph 11b. For example, the traffic obstruction device 11 may extend and retract by a hydraulic syringe that extends and retracts in the vertical direction.

[0028] (Second embodiment of the traffic obstruction device 11) Figure 5 is an explanatory diagram of a second embodiment of the traffic obstruction device 11 in the mechanical parking system 10 of the first embodiment. Figure 5(A) shows the traffic obstruction device 11 protruding inward from the exit path R, and Figure 5(B) shows the traffic obstruction device 11 retracted to the outside of the exit path R. The blocking portion 11g of the traffic obstruction device 11 in the second embodiment is a flat plate member that is thin enough for vehicles to drive over without obstructing the walking of users, etc. The operating device 11h is an actuator 11c, such as a motor, that rotates the flat plate member. When the charging station 5 is in a protruding position, the traffic obstruction device 11 rises from the floor of the passenger compartment 9 in the exit route R and blocks the exit route R. When the charging station 5 is in a retracted position, the motor lays the flat plate member down on the floor 9c of the passenger compartment 9. With this configuration, when the flat plate member of the traffic obstruction device 11 is laid down, vehicles and people can pass over the flat plate member. The other configurations of the traffic obstruction device 11 in the second embodiment are the same as in the first embodiment.

[0029] (Third embodiment of the traffic obstruction device 11) Figure 6 is an explanatory diagram of a third embodiment of the traffic obstruction device 11 in the mechanical parking system 10 of the first embodiment. Figure 6(A) shows the traffic obstruction device 11 protruding inward from the exit path R, and Figure 6(B) shows the traffic obstruction device 11 retracted to the outside of the exit path R. The traffic obstruction device 11 of the third embodiment differs from the first and second embodiments in that the blocking portion 11g protrudes from above into the inside of the exit route R. The traffic obstruction device 11 of the third embodiment may also be a display board 14 that repeatedly protrudes from and retracts from the top of the passageway 9a by the extension and retraction of a pantograph 11b. The pantograph 11b may be covered by a cover 11e.

[0030] The display board 14 may be a sign directly displaying instructions to users to store the charging station 5, or it may be an electronic display board. The traffic obstruction device 11 in this figure extends and retracts the pantograph 11b using an actuator 11c such as a hydraulic syringe. When the pantograph 11b extends, the display board 14 descends to a position visible from the driver's seat (for example, directly in front of the driver's seat). As a result, the traffic obstruction device 11 blocks the passage of the EV vehicle 1. In order to exit the parking lot without colliding with the traffic obstruction device 11, the display board 14 must be moved to the outside of the exit route R. When a user manually returns the charging station 5 to its retracted position, the pantograph 11b retracts and moves to a position above the exit route R (for example, above the passageway 9a). This opens the exit route R, allowing the EV vehicle 1 to exit. The other configurations of the traffic obstruction device 11 in the third embodiment are the same as in the first embodiment.

[0031] (Fourth embodiment of the traffic obstruction device 11) Figure 7 is an explanatory diagram of a fourth embodiment of the traffic obstruction device 11 in the mechanical parking system 10 of the first embodiment. Figure 7(A) shows the traffic obstruction device 11 protruding inward from the exit path R, and Figure 7(B) shows the traffic obstruction device 11 retracted to the outside of the exit path R. The traffic obstruction device 11 of the fourth embodiment also protrudes from above into the exit route R. The traffic obstruction device 11 of this embodiment has a structure in which a blocking part 11g is attached to the tip of an L-shaped rotating arm 11f mounted on the upper part of the passage 9a. A display board 14 may be attached to the blocking part 11g in a position visible from inside the vehicle on the pallet. The operating device 11h of this embodiment has this rotating arm 11f and an actuator 11c.

[0032] The rotating arm 11f is a rod-shaped member that extends perpendicularly to the upper wall surface of the passageway 9a and is bent at a right angle from its distal end. In this figure, an actuator 11c, such as a motor, is attached to the base of the rotating arm 11f. The rotation of the rotating arm 11f by the drive of the actuator 11c causes the display board 14 to swing between the outside and inside of the exit route R. The display board 14 may be a sign with a message for users directly written on it, or it may be an electronic display board.

[0033] With this configuration, the traffic blocking device 11 of the fourth embodiment, even with its simple structure, can obstruct the passage of the EV vehicle 1 by simply rotating the rotating arm 11f to make the blocking section 11g protrude above the exit path R. The other configurations of the traffic obstruction device 11 in the fourth embodiment are the same as those in the third embodiment.

[0034] (Fifth embodiment of the traffic obstruction device 11) Figure 8 is an explanatory diagram of a fifth embodiment of the traffic obstruction device 11 in the mechanical parking system 10 of the first embodiment. Figure 8(A) shows the traffic obstruction device 11 protruding inward from the exit path R, and Figure 8(B) shows the traffic obstruction device 11 retracted to the outside of the exit path R. The traffic obstruction device 11 of the fifth embodiment is a movable wheel stop provided on the upper surface 3a of the pallet 3, in the area in front of the front wheels 1a of the EV vehicle 1 parked on the pallet. The traffic obstruction device 11 of this embodiment has a wheel stop portion 11j that protrudes in the area in front of the front wheels 1a of the EV vehicle 1 parked on the pallet, on the upper surface 3a of the pallet 3 when the charging stand 5 is in the protruding position, and an actuator 11h that moves the wheel stop portion 11j between above the upper surface 3a of the pallet 3 and below the height of the upper surface 3a. The control device 13 controls the actuator 11h to protrude the wheel stop portion 11j onto the pallet when the charging stand 5 is in the protruding position. On the other hand, when the charging stand 5 is in the retracted position, the control device 13 retracts the wheel stop portion 11j to below the height of the upper surface 3a of the pallet 3. The actuator 11h may be a motor that rotates the wheel stop portion 11j as shown in this figure, or it may be a hydraulic syringe that moves the wheel stop portion 11j up and down.

[0035] In the fifth embodiment, the traffic obstruction device 11 uses voice guidance from a speaker (not shown) and a display board 14 to prompt users to retract the charging station 5. This allows users to be informed that the reason the wheel stop 11j is not retracting is because the charging station 5 is not retracted, even if the wheel stop 11j is not visible from the driver's seat.

[0036] Figure 9 is an explanatory diagram showing a mechanical parking system 10 that employs the fifth embodiment of the first embodiment, and is a two-tiered parking system. Figure 9(A) is a front view of the two-tiered parking system 10. Figure 9(B) is a perspective view from the passenger compartment 9 looking towards the passageway 9a. Note that in Figure 9(B), the control device 13, the operating device 11h, and the partition 23 are omitted from the description. The mechanical parking system 10 in the fifth embodiment may be a two-tiered parking system. When the mechanical parking system 10 is a two-tiered parking system, the boarding / alighting area on the first floor above ground where the vehicle enters corresponds to the boarding / alighting room 9 in this embodiment. In this example, the two-tiered parking system 10 is a three-tiered, ground-level, lift-and-traverse type, with three levels (1st, 2nd, and 3rd floors) of vehicle parking spaces provided in the same installation space.

[0037] In this example, the two pallets 3 located on the 1st floor of the three-tiered system can move horizontally, the two pallets 3 located on the 2nd floor can move horizontally and vertically, and the three pallets 3 located on the 3rd floor can only move vertically. Therefore, in this example, the number of vehicles that can be accommodated by vehicle 1 is 3 × 3 - 2 = 7.

[0038] In this example, the triple-tiered, two-level parking system has three entry / exit areas (entry / exit rooms 9) in installation spaces A, B, and C. The overall width of the pallets 3 is preferably the same, but may differ. The entry / exit areas in installation spaces A, B, and C are positioned adjacent to each other with the necessary gaps (e.g., 40 mm or less) between them.

[0039] The two pallets 3 located on the 1st floor have wheels 24a at both ends in the longitudinal direction and move horizontally along two horizontal rails 19 provided on the 1st floor by a horizontal drive device (not shown), allowing the EV vehicle 1 to be directly loaded into or unloaded from one of the passenger compartments 9 of the installation spaces A, B, or C.

[0040] The two pallets 3 located on the 2nd floor have wheels 24b at both ends in the longitudinal direction of the rectangular frame 18 that lifts them. The rectangular frame 18 surrounds the pallets 3 parked on the intermediate level between the top and bottom levels, suspending the pallets 3 and allowing them to move laterally. In this configuration, the two pallets 3 located on the 2nd floor move horizontally along a horizontal rail 19 provided on the 2nd floor by a horizontal drive device (not shown), allowing the EV vehicle 1 to be directly loaded into or unloaded from one of the boarding / unloading compartments 9 in installation spaces A, B, or C.

[0041] In this example, the two-tiered parking system 10 has a pallet 3 that can move up and down with the EV vehicle 1 on it between the entry / exit height (FL) in which the EV vehicle 1 enters and exits, and a parking space above this entry / exit height. These movable pallets 3 include the two pallets 3 located on the 2nd floor and the three pallets 3 located on the 3rd floor, as mentioned above.

[0042] In this example, the two-tiered parking system 10 is further equipped with a lifting drive device 21 to raise and lower the pallet 3. The lifting drive device 21 raises or lowers the lower end of a flexible cord member 20 (chain or wire) that extends vertically at a position that does not interfere with the EV vehicle 1 by winding up or unwinding it.

[0043] The lifting drive device 21 for the second floor is fixed to the rectangular frame 18 and moves horizontally along with the rectangular frame 18. The lifting drive device 21 for the 3rd floor is fixed to the main frame and is designed to independently raise and lower each of the three pallets 3 from the main frame.

[0044] In this example, the lower ends of the four string members 20 are fixed to a total of four locations on the front and rear of the pallet 3, taking into consideration the load balance, and the lifting drive device 21 allows the pallet 3 to be raised and lowered while being held horizontally.

[0045] As shown in Figure 9(A), the two-tiered parking system 10 of this embodiment is equipped with an opening / closing door 9b that opens and closes the passageway 9a to the entry / exit area on the first floor above ground. The opening / closing door 9b is supported so as to be able to move up and down by door support columns 22 that are erected vertically on both the left and right sides of the passageway 9a. The two-tiered parking system 10 is equipped with partitions 23, such as fences or walls, on its left and right sides and rear, preventing people from entering the passenger compartment 9 from any location other than the passageway 9a.

[0046] In the case of a two-tiered multi-stage parking system 10 in which the passageway 9a opens when the opening / closing door 9b rises, a sign board 14 may be attached to the passenger compartment side (pallet side) of the opening / closing door 9b, as shown in Figure 9(B). This allows the sign board 14 to be raised to a higher position when the opening / closing door 9b is opened, so that the sign board 14 can be seen by passengers in the driver's seat, etc. The other configurations of the traffic obstruction device 11 in the fifth embodiment are the same as in the first embodiment.

[0047] Next, the operation of the mechanical parking device 10 with charging function according to the first embodiment will be described. Figure 10 shows the operation flow of the mechanical parking system 10 with charging function when entering the parking space according to the first embodiment. As shown in Figure 10, the user or other person operates the input device 15 to call up the pallet 3. The input device 15 may be, for example, an operation panel, a dedicated remote control, or a smartphone with a dedicated app downloaded.

[0048] When the control device 13 of the mechanical parking system 10 receives an operation signal from the input device 15 to instruct parking, it moves the target empty pallet 3 from the storage rack 4 to the passenger compartment 9 and places it in the boarding area of ​​the passenger compartment 9. At this time, the control device 13 keeps the passage blocking device 11 retracted into the retraction hole 11a. After that, it opens the opening / closing door 9b.

[0049] Users drive the EV vehicle 1 into the passenger compartment 9 from the entrance 9a and stop on the pallet 3. Then, users raise the charging stand 5 on the pallet 3 to its protruding position and connect the charging stand 5 and the power supply port of the EV vehicle 1 with the charging cable 5a. Next, the user or other person enters an instruction into the input device 15 to exit through the passageway 9a and close the opening / closing door 9b.

[0050] Upon receiving an operation signal from the input device 15 to close the opening / closing door 9b, the control device 13 closes the opening / closing door 9b and stores the pallet 3 located in the boarding area into an empty storage shelf 4. The other aspects of the parking flow for the mechanical parking system 10 of the present invention are the same as those of a conventional mechanical parking system with a charging function.

[0051] Next, we will explain the process of exiting the parking space. Figure 11 shows the operation flow of the mechanical parking system 10 with charging function of the first embodiment when exiting the parking space. When the control device 13 of the mechanical parking system 10 receives an operation signal from the input device 15 to instruct the vehicle to exit, it pulls out the pallet 3 on which the target EV vehicle 1 is placed from the storage shelf 4, moves it to the passenger compartment 9, and places it in the passenger area. At this time, the control device 13 starts detection by the monitoring device 7. The monitoring device 7 continuously outputs attitude signals to the control device 13, indicating whether the charging station 5 is in an extended position or a retracted position.

[0052] If the input attitude signal indicates that the charging station 5 is in a protruding position, the control device 13 extends the traffic blocking device 11 inward along the exit path R and opens the opening / closing door 9b. Subsequently, the monitoring device 7 continues to detect the attitude of the charging station 5. On the other hand, if the attitude signal indicates that the charging stand 5 is in the stowed position, the control device 13 opens the opening / closing door 9b while keeping the passage blocking device 11 retracted into the retraction hole 11a.

[0053] When the opening door 9b opens, users enter the passenger compartment 9 and disconnect the charging cable 5a from the charging station 5 and the EV vehicle 1. During this time, the mechanical parking system 10 continues to detect the orientation of the charging station 5 using the monitoring device 7. When a user places the charging station 5 into the storage compartment 5b, the monitoring device 7 detects this and outputs a posture signal indicating that the charging station 5 is in the stored position. When the control device 13 receives this posture signal, the control device 13 controls the traffic obstruction device 11 to move it out of the exit route R. As a result, there is no obstacle (traffic obstruction device 11) in the exit route R, and the exit route R becomes open. The user then boards the EV vehicle 1 and drives it out of the passenger compartment 9 through the passageway 9a.

[0054] Upon exiting through the entrance 9a, the user or other party stops the vehicle and operates the input device 15 to close the opening / closing door 9b. For example, if the input device 15 is a control panel mounted on the exterior wall of the mechanical parking system 10, the user gets out of the vehicle and operates the control panel to close the opening / closing door 9b. If the input device 15 is a remote control or smartphone, the user or other party may operate these from the driver's seat to input an operation signal to the mechanical parking system 10. At this time, a confirmation message for the user, etc., regarding whether the charging stand 5 has been successfully stored may be displayed on the control panel's operation screen or the smartphone screen.

[0055] The control device 13, upon receiving the operation signal, controls the mechanical parking device 10 to close the opening / closing door 9b and store the pallet 3 in the storage rack 4.

[0056] In this embodiment, the mechanical parking system 10 with a charging function deploys the traffic blocking device 11 to the exit route R when a user forgets to put away the charging stand 5, physically preventing the vehicle from leaving the passenger compartment 9 and prompting the user to put away the charging stand 5. Once the mechanical parking system 10 confirms that the user has put away the charging stand 5, it retracts the traffic blocking device 11 from the exit route R, allowing the vehicle to pass through the exit route R. This ensures that the mechanical parking system 10 can reliably prevent users from forgetting to put away the charging stand 5.

[0057] (Second Embodiment) Figure 12 is an explanatory diagram of the mechanical parking device 10 with charging function according to the second embodiment. Figure 12(A) is an explanatory diagram of the remote control, which is the input device 15 of this embodiment. Figure 12(B) is an enlarged view of the charging stand 5 in its protruding position, and Figure 12(C) is an enlarged view of the charging stand 5 in its retracted position. In this embodiment, the mechanical parking device 10 does not require the user to manually retract the charging stand 5. Instead, the user triggers the output of an operation signal input to the input device 15, and the control device 13 controls the retraction of the charging stand 5. In the second embodiment, the mechanical parking device 10 with a charging function includes an input device 15 and a drive device 5c that drives the charging stand 5 between an extended position and a retracted position. The control device 13 controls the drive device 5c according to the operation signal input from the input device 15.

[0058] The input device 15 receives instructions from the user or others to the control device 13 and outputs them as operation signals, such as a remote control or a smartphone with a dedicated app downloaded. The operation screen of the dedicated app or the remote control is equipped with buttons to store the charging stand 5 and to raise it, such as the "Store / Raise" button in Figure 12(A). In this diagram, the "Call" button on the remote control is used to call the target pallet 3, and the "Open" and "Close" buttons are used to instruct the opening and closing of the door 9b. The "Emergency Stop" button at the bottom is used to urgently stop the operation of the mechanical parking device 10.

[0059] As shown in Figures 12(B) and 12(C), the charging stand 5 of this embodiment deforms between an extended position and a retracted position by the drive of a drive device 5c, such as a motor or a hydraulic syringe. With this configuration, in the mechanical parking device 10 of the second embodiment, the mechanical parking device 10 itself performs the retraction operation of the charging stand 5 when the user presses or taps the "retract / raise" button. This is one of the differences between the mechanical parking device 10 of the second embodiment and the mechanical parking device 10 of the first embodiment, in which the user manually moved the charging stand 5.

[0060] Next, the operation of the mechanical parking device 10 with charging function of the second embodiment will be described. The operation when parking in this embodiment is the same as that of the first embodiment. Figure 13 shows the operation flow of the mechanical parking system 10 with charging function during exit according to the second embodiment. The exit operation of the mechanical parking system 10 with charging function in the second embodiment differs from the first embodiment in the following two points. First, the monitoring device 7 monitors the posture of the charging stand 5 until the opening / closing door 9b is opened. Second, when a user instructs the charging stand 5 to be stored by pressing or tapping the "store / stand" button on the input device 15, the resulting operation signal triggers the passage obstruction device 11 to retract simultaneously with the storage of the charging stand 5. At this time, the storage of the charging stand 5 and the retraction of the passage obstruction device 11 can occur in any order, or they can occur simultaneously.

[0061] The control device 13 begins receiving operation signals after opening the passageway 9a. When the control device 13 receives an operation signal from the input device 15 to put the charging stand 5 into the retracted position, it controls the drive device 5c to put the charging stand 5 into the retracted position. At the same time, the control device 13 controls the passage blocking device 11 to open the exit route R.

[0062] In this embodiment, the mechanical parking device 10 is triggered by pressing or tapping the "Store / Stand Up" button to initiate the retraction of the charging stand 5, thus allowing for user intervention. This prevents the charging stand 5 from retracting without user instruction, thus preventing situations such as the charging stand 5 retracting before the charging cable 5a is disconnected.

[0063] Furthermore, when manually storing the charging stand 5, the user must bend down to the point where their hand touches the top surface 3a of the pallet 3. This posture places a significant burden on wheelchair users and users with disabilities. However, in the mechanical parking device 10 of the second embodiment, the mechanical parking device 10 stores the charging stand 5, eliminating the need for any work to be performed near the top surface 3a of the pallet 3. Therefore, with the mechanical parking device 10 of this embodiment, wheelchair users and users with disabilities can park the EV vehicle 1 with peace of mind. Other configurations, operations, and effects of this embodiment are the same as those of the first embodiment.

[0064] (Third embodiment) The mechanical parking system 10 with a charging function in the third embodiment has a pass-through type passenger compartment 9. Figure 14 is a plan view of the passenger compartment 9 of the mechanical parking system 10 with a charging function according to the third embodiment. This figure illustrates a tandem-type elevator parking system. In this embodiment, the mechanical parking system 10 has an entrance 17 for entry into the passenger compartment 9, separate from the exit passage 9a for exiting the parking space.

[0065] This passenger compartment 9 is equipped with an entrance door 17A at an entrance 17, which is separate from the exit passage 9a. When the passenger compartment 9 has an entrance 17 separate from the exit passage 9a, the traffic blocking device 11 may be an opening / closing door 9b that opens and closes the exit passage 9a. In other words, the opening / closing door 9b of the exit passage 9a may be used as the traffic blocking device 11 that blocks the exit route R until it is confirmed that the charging station 5 is in the stowed position.

[0066] Next, the operation of the mechanical parking device 10 with a charging function according to the third embodiment will be described. In the third embodiment, when a user calls for the target pallet 3, the entrance door 17A opens while the exit passage 9a remains closed, and the user enters the passenger compartment 9 through the entrance 17. The user parks the EV vehicle 1 on the pallet in the passenger compartment, extends the charging stand 5, and connects the charging stand 5 and the EV vehicle 1 with the charging cable 5a. Then the user exits the passenger compartment 9 and closes the entrance door 17A. After that, the mechanical parking system 10 stores the pallet 3 in the passenger compartment in the storage shelf 4.

[0067] Figure 15 shows the operation flow of the mechanical parking system 10 with charging function of the third embodiment when the vehicle is being taken out of the parking space. In the exit operation of the mechanical parking system 10 in the third embodiment, first, a user or the like calls for the target pallet 3, and the mechanical parking system 10 moves the pallet 3 to the boarding area of ​​the passenger compartment 9. Then, while keeping the opening / closing door 9b closed, the mechanical parking system 10 opens the entrance door 17A and starts detecting the posture of the charging station 5 using the monitoring device 7. The user or the like enters the passenger compartment 9 through the entrance 17, which has the entrance door 17A opened. The control device 13 continues to keep the opening / closing door 9b closed as long as the charging station 5 is in the protruding position.

[0068] Next, when it is determined that the charging stand 5 is in the retracted position, the control device 13 opens the opening / closing door 9b of the exit passage 9a. "When it is determined that the charging stand 5 is in the retracted position" means when a position signal indicating that the charging stand 5 is in the retracted position is input, as in the first embodiment, or when an operation signal to put the charging stand 5 in the retracted position is input, as in the second embodiment. Subsequently, the user drives the EV vehicle 1 out of the passenger compartment 9 through the open exit passage 9a and performs a door closing operation on the input device 15 of the mechanical parking system 10. This operation causes the mechanical parking system 10 to close the entrance door 17A of the entrance 17 and the opening / closing door 9b of the exit passage 9a, and to store the pallet 3 in the storage rack 4.

[0069] As a result, in this embodiment, the mechanical parking system 10 can use the opening and closing door 9b as a traffic obstruction device 11 simply by changing the operation of the mechanical parking system 10, without having to newly install a traffic obstruction device 11. Other configurations, operations, and effects of this embodiment are the same as those of the first or second embodiment.

[0070] (Fourth Embodiment) Figure 16 is a plan view of the passenger compartment 9 of the mechanical parking system 10 with charging function according to the fourth embodiment. The passenger compartment 9 in this embodiment has an entrance 17 that people can enter and exit, separate from the passageway 9a. A passenger door 17B is installed at the entrance 17. Similar to the third embodiment, even if the passenger compartment 9 is provided with an entrance 17 separate from the passageway 9a, the opening and closing door 9b of the passageway 9a may be the passage blocking device 11.

[0071] Next, the operation of the mechanical parking device 10 with charging function of the fourth embodiment will be described. The parking operation of this embodiment is the same as that of the first embodiment. Figure 17 shows the operation flow of the mechanical parking system 10 with charging function during exit according to the fourth embodiment. In the exit operation of the mechanical parking system 10 in this embodiment, first, a user calls for the target pallet 3, and the mechanical parking system 10 moves the target pallet 3 to the boarding area of ​​the boarding / alighting room 9. Then, the mechanical parking system 10 unlocks the passenger door 17B while keeping the opening / closing door 9b of the passageway 9a closed, and invites the user from the entrance 17 into the boarding / alighting room 9. After that, the mechanical parking system 10 starts detecting the posture of the charging stand 5 using the monitoring device 7. The control device 13 keeps the opening / closing door 9b closed as long as the charging stand 5 is in the protruding position.

[0072] Next, when it is confirmed that the charging station 5 is in the retracted position, the opening door 9b of the passageway 9a is opened. After that, the user drives the EV vehicle 1 out of the passenger compartment 9 through the opened passageway 9a, stops the EV vehicle 1, and operates the input device 15 to close the opening door 9b. With this operation, the mechanical parking system 10 closes the opening door 9b of the passageway 9a and stores the pallet 3 in the storage rack 4. Other configurations, operations, and effects of this embodiment are the same as those of the third embodiment.

[0073] (Fifth embodiment) The mechanical parking system 10 of the fifth embodiment uses the opening and closing door 9b as a traffic obstruction device 11 by changing the degree to which the opening and closing door 9b is opened. The front view of the mechanical parking system 10 of the fifth embodiment is the same as that of Figure 9(A). Figure 18 is a partial perspective view. More specifically, Figure 18 is a perspective view of the first floor above ground of the mechanical parking system 10 with a charging function of the fifth embodiment shown in Figure 9(A), as seen from the front of the mechanical parking system 10. This figure shows a two-tiered multi-stage parking system in which the passageway 9a opens when the opening / closing door 9b rises, as an example of the mechanical parking system 10.

[0074] Note that this figure omits the depiction of the second floor and above of the two-tiered parking system 10, the support columns of the frame body, and the control device 13. Of course, this embodiment of the mechanical parking system 10 can also be applied to mechanical parking systems other than the two-tiered parking system. This two-tiered parking system 10 opens and closes the passageway 9a leading to the boarding / alighting area on the first floor using a retractable door 9b.

[0075] Figure 18(A) shows the door 9b in a half-open position. As shown in this figure, in the exit operation of the two-tiered parking device 10 of this embodiment, when a user calls the target pallet 3 to the boarding / alighting area (boarding / alighting room 9), the control device 13 opens the opening / closing door 9b to a half-open state. In this invention, "half-open state" means that the opening / closing door 9b is opened so that the passageway 9a is large enough for a person to pass through but not for an EV vehicle 1. In the example shown in this figure, the lower end of the opening / closing door 9b is lower than the height of the roof of the EV vehicle 1, but the opening / closing door 9b of the passageway 9a is opened to a height that allows a user to pass under the opening / closing door 9b by bending down, thereby maintaining the opening / closing door 9b in a half-open state.

[0076] By keeping the opening / closing door 9b half-open, users can pass through the door 9b and enter the passenger compartment 9. Also, the passageway 9a below the opening / closing door 9b is not yet open enough for the EV vehicle 1 to pass through, so the opening / closing door 9b can block the exit route R for the EV vehicle 1. In other words, the half-open opening / closing door 9b in this figure can be said to be a passage blocking device 11 that protrudes from above the exit route R into the inside of the exit route R. Therefore, by maintaining the opening / closing door 9b in a half-open state, the opening / closing door 9b can be used as a passage blocking device 11 even if there is no other entrance to the passenger compartment 9 besides the passageway 9a, as in the third and fourth embodiments. Next, after the opening / closing door 9b is left partially open, the control device 13 prompts users to store the charging stand 5 by using voice guidance from a display panel 14 located on the passenger compartment side of the opening / closing door 9b and from a speaker (not shown).

[0077] Figure 18(B) shows the door 9b when it is fully open. When a user places the charging station 5 inside, the control device 13 detects this using a monitoring device 7 (not shown) and fully opens the opening / closing door 9b. This causes the passage blocking device 11, which is the opening / closing door 9b, to move to the outside of the exit route R (above the exit route R), and the exit route R becomes open. Subsequently, the user drives the EV vehicle 1 out of the passenger compartment 9 through the opened passageway 9a, stops the EV vehicle 1, and operates the input device 15 to close the opening / closing door 9b. This operation causes the two-tiered parking system 10 to close the opening / closing door 9b of the passageway 9a and store the pallet 3 in the storage rack 4. Other configurations, operations, and effects of this embodiment are the same as those of the first to fourth embodiments.

[0078] In this example, the case where the opening / closing door 9b opens and closes by raising and lowering is used as an example, but this embodiment can also be used in a mechanical parking device 10 where the opening / closing door 9b opens and closes by traversing. In that case, the "half-open state" refers to a state where the width of the opened passage 9a is smaller than the width of the EV vehicle 1, but the opening / closing door 9b is wide enough for users to pass through. The configuration, operation, and effects when the opening / closing door 9b opens and closes by traversing are the same as when the opening / closing door 9b opens and closes by raising and lowering as described above.

[0079] (Sixth Embodiment) The mechanical parking system 10 of the sixth embodiment is a two-tiered multi-level parking system in which the opening door 9b descends to the underground, thereby opening the passageway 9a. Figure 19 is a perspective view showing a portion of the first floor above ground of the mechanical parking system 10 with charging function of the sixth embodiment. Figure 19(A) is a perspective view of the two-tiered multi-level parking system 10 as seen from the outside.

[0080] This figure illustrates a two-tiered multi-level parking system 10 with three levels (1st floor, 2nd floor, and 3rd floor) of vehicle parking spaces provided in the same installation space. In this example, the four pallets 3 located on the 1st floor can move horizontally, the four pallets 3 located on the 2nd floor can move horizontally and vertically, and the five pallets 3 located on the 3rd floor can only move vertically. Therefore, in this example, the number of vehicles that can be accommodated by vehicle 1 is 3 × 5 - 2 = 13.

[0081] Figure 19(B) is a perspective view of the entrance / exit compartment 9 of the two-tiered parking system 10, looking at the passageway 9a. In this figure, the support columns of the frame body of the two-tiered parking system 10, the control device 13, and the partition 23 are omitted from the depiction. In this embodiment, the opening and closing door 9b is supported by a vertically standing door support 22 so as to be able to move up and down between the ground floor (1F) and the basement. The blocking portion 11g of the passage blocking device 11 in this embodiment is a plate-shaped or rod-shaped member provided on the back side (passenger compartment side) of the door support 22. This blocking portion 11g is provided so as to be able to rotate between a vertical position overlapping the door support 22 and a horizontal position protruding into the exit route R. The operating device 11h that rotates the blocking portion 11g may be, for example, a motor. With this configuration, the passage blocking device 11 in this embodiment can protrude from the side of the exit route R into the inside. Furthermore, it is preferable that the length of the blocking portion 11g is less than two-thirds of the width of the passage opening 9a and longer than one-third. This allows users to enter the passenger compartment 9 while avoiding the blocking portion 11g, even when the blocking portion 11g is protruding into the exit route R.

[0082] The traffic obstruction device 11 may be provided on all door support posts 22, but it is preferable that it be provided on every other door support post 22. When the traffic obstruction device 11 is provided on every other door support post 22, one end of the traffic obstruction device 11 is designed to be able to rotate either clockwise or counterclockwise so that it can protrude into either the left or right passenger compartment 9. This allows one traffic obstruction device 11 to serve both the left and right passenger compartments 9, thus reducing the number of traffic obstruction devices 11 that need to be installed.

[0083] Figure 20 is an explanatory diagram of the operation of the mechanical parking system 10 with charging function of the sixth embodiment when it is exiting the parking space. This figure is also a perspective view of the passageway 9a from inside the passenger compartment 9 of the two-tiered parking system 10. In this figure, the support columns of the frame body of the two-tiered parking system 10, the control device 13, and the partition 23 are omitted from the depiction.

[0084] In the exit operation of the two-tiered parking system 10 of this embodiment, first, the user or other person calls the target pallet 3 to the boarding / alighting area (boarding / alighting room 9) on the first floor above ground. The control device 13 rotates the blocking part 11g of the passage blocking device 11 towards the boarding / alighting room 9 where the called pallet 3 is placed, causing the passage blocking device 11 to protrude into the passageway 9a. Next, the opening / closing door 9b is opened. The opening / closing door 9b descends into the underground space, and the passageway 9a opens (Figure 20(A)). As a result, the user or other person can enter the boarding / alighting room 9 from the passageway 9a, avoiding the passage blocking device 11. Note that a message prohibiting entry into the boarding / alighting room 9 by anyone other than the driver may be written on the front side of the passage blocking device 11 (the front side of the two-tiered parking system 10).

[0085] The passage blocking device 11 protrudes inward into the exit route R by extending its other end from the door support column 22 toward the passageway 9a, thereby obstructing the passage of the EV vehicle 1. Preferably, a display board 14 is provided on the pallet side (the rear side of the two-tiered parking device 10) of the traffic obstruction device 11 to display a message prompting the retraction of the charging station 5. This allows the message prompting the retraction of the charging station 5 to be visible to the driver or other user when the traffic obstruction device 11 protrudes into the passageway 9a.

[0086] When a user or other user places the charging station 5 inside, the control device 13 detects this using a monitoring device 7 (not shown) and rotates the traffic blocking device 11 until it is vertical (i.e., until it aligns with the door support column 22). This moves the traffic blocking device 11 to the outside of the exit route R, opening the exit route R. After that, the user or other user drives the EV vehicle 1 out of the entrance 9a and exits the passenger compartment 9, stops the EV vehicle 1, and closes the opening / closing door 9b using the input device 15. Thus, the passage blocking device 11 of the present invention can also be used in a two-tiered multi-stage parking system 10 in which the passageway 9a opens when the opening / closing door 9b descends underground. Other configurations, operations, and effects of this embodiment are the same as those of the first to fifth embodiments.

[0087] According to the present invention described above, while the charging stand 5 is in a protruding position when exiting the parking area, the traffic blocking device 11 protrudes inward from the exit path R to block the passage of the EV vehicle 1, and after it is confirmed that the charging stand 5 is in a retracted position, the traffic blocking device 11 retracts to the outside of the exit path R. As a result, the mechanical parking system 10 with charging function of the present invention can reliably retract the charging stand 5 when users who have used the charging stand 5 are exiting the parking area.

[0088] Furthermore, since it is possible to reliably prevent the charging station 5 from being left extended, subsequent users can exit the parking lot smoothly. Also, since subsequent users do not need to drive recklessly to avoid the charging station 5, collisions between the charging station 5 and the EV vehicle 1 can be prevented.

[0089] Furthermore, since the traffic blocking device 11 blocks the exit route R to prevent the EV vehicle 1 from passing, even if the EV vehicle 1 accidentally starts moving, it can be prevented from flying out of the mechanical parking device 10.

[0090] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0091] (1) The mechanical parking system 10 may have two entry / exit compartments 9, one for entering and one for exiting. In this case, the entry / exit compartment does not have a traffic blocking device 11, and the exit / exit compartment 9 does not have a traffic blocking device 11. The other configurations, operations, and effects of this embodiment are the same as those of the first to fourth embodiments.

[0092] (2) The pallets of the mechanical parking system 10 may all be charging pallets 3, or some of them may be charging pallets 3. If the charging pallets 3 are part of the pallets provided by the mechanical parking system 10, the pallets 3 are installed in the passenger compartment 9 when a user of the EV vehicle 1 calls for a pallet.

[0093] (3) In the event that the monitoring device 7 malfunctions, the traffic blocking device 11 may not be extended when the vehicle is being taken out of storage. Instead, a message confirming that the charging stand 5 has been stored may be displayed on the control panel screen or on the user's smartphone. [Explanation of Symbols]
