Description

[Technical Field]

[0001] The present invention relates to a mechanical parking device with a charging function for electric vehicles. [Background technology]

[0002] In recent years, electric vehicles (EVs) powered by electric motors have become popular, replacing ordinary gasoline-powered vehicles. EVs are environmentally friendly because they reduce exhaust gas emissions, but instead of refueling with gasoline, they require batteries to be charged. For this reason, mechanical parking devices with charging functions have been developed that charge EVs while they are parked in mechanical parking devices. In such mechanical parking devices with charging functions, for example, a charging stand for power supply is installed on the pallet on which the EV vehicle is mounted. When entering the parking lot, the user connects the EV vehicle to the charging stand with a charging cable. The EV vehicle remains connected to the charging stand on the pallet and is stored in a storage space in the mechanical parking device until it leaves the parking lot. Such a mechanical parking device is disclosed, for example, in Patent Document 1. The mechanical parking device disclosed in Patent Document 1 is equipped with a foldable charging stand on a pallet, with a charging plug connection part attached in a position that is on the upper side when the parking device is upright. Users of the mechanical parking device raise the charging stand when charging and fold it down when it is not needed. When the detection device detects that the charging stand is upright, the mechanical parking device of Patent Document 1 provides guidance regarding the storage of the charging equipment by providing audio guidance through a speaker, visual guidance using an information monitor installed near the entrance and exit, and illuminating a warning light.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-84663 Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, in the mechanical parking system of Patent Document 1, the charging stand is stored by the user of the mechanical parking system. However, since the action of "storing the charging stand" is performed by a human, "forgetting to put the charging stand away" will occur no matter how much the machine warns the user. This meant that the next user using the pallet with the charging stand left out had to perform the extra steps of "getting out of their car, entering the parking area, lowering the charging stand, returning from the parking area, and getting into their car" before entering the parking lot. This reduced convenience for users and reduced the speed of parking. This extra step was particularly burdensome for wheelchair users and physically disabled users. Therefore, it was necessary to eliminate the possibility of this happening in mechanical parking devices with charging functions.

[0005] On the other hand, if the setting up and retracting of the charging stand were left to the automatic control of the mechanical parking system, there is a possibility that the mechanical parking system would start retracting the charging stand before the user had disconnected the charging cable from the charging stand and the EV. To avoid this, human intervention is always required when retracting the charging stand. Therefore, in order to operate a mechanical parking device with a charging function conveniently and safely, it was necessary to create a system that ensures that a person stores the charging stand when leaving the parking lot.

[0006] The present invention has been devised to solve the above-mentioned problems. That is, an object of the present invention is to provide a mechanical parking device with a charging function that reliably stores the charging stand when the vehicle leaves the parking lot. [Means for solving the problem]

[0007] According to the present invention, a pallet for carrying an EV vehicle on its upper surface; a charging stand capable of supplying power to the electric vehicle in a protruding position protruding above the upper surface of the pallet and capable of transforming between the protruding position and a stored position stored below the height of the upper surface; a boarding and disembarking room in which the pallet is placed; a traffic blocking device that protrudes inward of the exit route along which the electric vehicle passes when leaving the parking lot, thereby blocking the passage of the electric vehicle; a control device for controlling the operation of the traffic blocking device, A mechanical parking device with a charging function is provided, in which the control device extends the traffic blocking device toward the inside of the exit path when the charging stand is in the extended position, and retracts the traffic blocking device toward the outside of the exit path when it is determined that the charging stand is in the stored position. [Effects of the Invention]

[0008] According to the present invention, when the charging station is in the extended position during exit, the traffic blocking device extends to the inside of the exit path to prevent the EV from passing through, and then retracts to the outside of the exit path after it is confirmed that the charging station is in the retracted position. This allows the mechanical parking device with charging function of the present invention to reliably retract the charging station when the user exits the parking lot.

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, common parts in the drawings are given the same reference numerals, and duplicated explanations will be omitted.

[0011] FIG. 1 is a front view showing an example of a mechanical parking device 10. As shown in FIG. In this example, the mechanical parking device 10 is an elevator parking device. In this diagram, 1 is an EV vehicle, 2 is an elevator shaft, 3 is a pallet on which EV vehicle 1 is placed while charging, 4 is a storage shelf, 6 is a cage that moves through elevator shaft 2, 8 is the main frame, 9 is the boarding and disembarking area where EV vehicle 1 enters and leaves the facility, and 12 is a traction-type (friction-driven) hoist installed on top of main frame 8.

[0012] In this example, the cage 6 carries the pallets 3 and moves up and down the hoistway 2. The storage shelves 4 are arranged along the hoistway 2 and store the pallets 3, respectively.

[0013] In addition, the mechanical parking device 10 of the present invention is not limited to elevator parking, and may be any other mechanical parking device, such as a vertical circulation type parking device, a horizontal circulation type parking device, or a flat round-trip type parking device, as long as it is equipped with a pallet 3 and a boarding / disembarking space 9. Furthermore, although the pallet 3 is a flat pallet in this example, the present invention is not limited to this, and it may be a folded pallet, a skewer-type cage, or a conveyor device.

[0014] Fig. 2 is a view taken along the line AA in Fig. 1. This figure shows a plan view of the boarding / deboarding compartment 9. In this figure, the mechanical parking device 10 comprises a boarding / disembarking room 9, a pallet 3 installed at the boarding area of ​​the boarding / disembarking room 9, a charging stand 5 that supplies power to an EV vehicle 1 on the pallet, a monitoring device 7 for the charging stand 5, a traffic prevention device 11, and a control device 13.

[0015] In this figure, a pallet 3 is installed in the center of the boarding / deboarding room 9. The mechanical parking device 10 is configured so that a user or a manager of the mechanical parking device 10 (hereinafter referred to as the user) drives an electric vehicle 1 and places it on the top surface 3a of the pallet 3 to enter the device. An electric door 9b is provided at the entrance 9a of the boarding / deboarding room 9. The entrance 9a is the entrance to the boarding / deboarding room 9 through which the electric vehicle 1 passes when leaving the device.

[0016] A charging stand 5 for supplying power to the mounted EV 1 is provided on the pallet 3. The charging stand 5 is provided so as to be able to change between a protruding position in which it protrudes above the upper surface 3a of the pallet 3 when supplying power, and a stored position in which 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 FIG. 2 is provided so as to be rotatable at its base, and can swing between the protruding position and the stored position. In the example shown in this figure, 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 position and the retracted position is not limited to the swinging motion described above. For example, the charging stand 5 may change its position between the extended position and the retracted position by extending or contracting. A user or the like can manually change the position of the charging stand 5.

[0017] Whether the charging stand 5 is in the protruding position or the retracted position is monitored by a monitoring device 7. The monitoring device 7 is a device that detects whether the charging stand 5 protrudes above the upper surface 3a of the pallet 3. For example, a human detection sensor or a vehicle position detection sensor that is originally attached to the mechanical parking device 10 may be used as the monitoring device 7. In this case, for example, the position of the charging stand 5 is detected at the same time as the presence or absence of a human and the position of the vehicle.

[0018] For example, the monitoring device 7 may be a 3DLiDAR 7a that detects the position of the vehicle, people, and the posture of the charging stand 5. Alternatively, the monitoring device 7 may be a photocell sensor 7b that detects the charging stand 5 in a protruding posture, as shown in FIG. 2. Alternatively, the monitoring device 7 may be a proximity sensor 7c. When the monitoring device 7 is a proximity sensor 7c, as shown in FIG. 2, the proximity sensor 7c that detects the charging stand 5 may be provided inside the storage room 5b, or the proximity sensor 7c that detects the inner wall of the storage room 5b may be provided in the charging stand 5.

[0019] A traffic blocking device 11 is provided on the exit route R that the electric vehicle 1 takes when leaving the parking lot. For example, the exit route R is a virtual three-dimensional space that is the range that the body of the electric vehicle 1 may pass through when leaving the parking lot. In this case, the area below the floor height of the boarding / exiting compartment 9 corresponds to the "outside of the exit route R." This is because, regardless of the type of car parked, the tires cannot reach below the floor height. Furthermore, the space at least above the height of the entrance 9a also corresponds to the "outside of the exit route R." This is because only cars with roof heights lower than the height of the entrance 9a can enter the boarding / exiting compartment 9. On the other hand, the "inside of the exit route R" corresponds to a virtual space in front of the front of the EV 1 on the pallet placed in the boarding area and lower than the height of the entrance 9a.

[0020] The mechanical parking device 10 also includes a control device 13. The control device 13 controls the operation of the entire device included in the mechanical parking device 10, such as opening and closing the opening and closing door 9b, driving the traffic blocking device 11, transporting the pallet 3, and detection by the monitoring device 7.

[0021] Specific embodiments of the present invention will be described below. (First embodiment) Fig. 3 is a perspective view of the boarding / deboarding compartment 9 in the first embodiment of the present invention. Fig. 3(A) shows the charging stand 5 before it is stored when leaving the garage, and Fig. 3(B) shows the charging stand 5 after it is stored when leaving the garage. When the opening and closing door 9b opens upon leaving the parking lot, the pallet 3 carrying the EV 1 to be departed is placed in the boarding and disembarking compartment 9. At this point, the charging stand 5 is still standing (in a protruding position), and the charging stand 5 and the EV 1 are connected by a charging cable 5a.

[0022] In this embodiment, the traffic blocking device 11 is provided between the front end 3b of the pallet 3 installed in the boarding / alighting compartment 9 and the entrance 9a, and is extendable between a visibility height H at which users can see the vehicle from the driver's seat of the electric vehicle 1 and the floor height F of the boarding / alighting compartment 9. A retraction hole 11a for storing the traffic blocking device 11 is provided in the floor 9c between the front end 3b of the pallet 3 installed in the boarding / alighting compartment 9 and the entrance 9a. As shown in FIG. 3(A), when the charging stand 5 is in the protruding position at the time of leaving the parking lot, the traffic blocking device 11 extends from the retraction hole 11a to the visibility height H and blocks the passage of the electric vehicle 1. Users can enter the boarding / alighting compartment 9 from the entrance 9a and pass by the traffic blocking device 11 to head toward the electric vehicle 1.

[0023] In the example shown in the figure, a sign 14 is provided on the upper end of the traffic blocking device 11 and on the wall above the entrance 9a so that it can be seen by users and the like from the driver's seat of the EV 1. This sign 14 displays information encouraging users and the like to store the charging stand 5. For example, the sign 14 may be an electronic sign that alternates between the words "Charging stand" and "Store away." This makes it clear to users and the like that the reason the traffic blocking device 11 will not lower is because "the charging stand 5 has not been stored." The sign 14 may be provided both near the entrance 9a and on the upper end of the traffic blocking device 11, or may be provided on only one of them. The mechanical parking device 10 may also be equipped with a speaker to prompt users to store the charging stand 5 using audio guidance.

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

[0025] The traffic blocking device 11 is installed in an evacuation hole 11a opened in the floor 9c of the boarding / de-boarding room 9 and extends and retracts between the visibility height H and floor level 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 to prevent users from falling into the evacuation hole 11a even if they step on it during evacuation. When the traffic blocking device 11 is retracted, the top surface of this case 11d becomes flush with the floor 9c of the boarding / de-boarding room 9, blocking the evacuation hole 11a. This allows users to safely walk around the boarding / de-boarding room 9. The operation of the actuator 11c is controlled by the control device 13 of the mechanical parking device 10.

[0026] Furthermore, the pantograph 11b of the traffic blocking device 11 of this embodiment is preferably covered with a cover 11e made of a sheet-like material. This cover 11e may be made of, for example, accordion-shaped resin or cloth. This allows the cover 11e to prevent users and the like from coming into contact with the pantograph 11b, thereby preventing accidents such as pinching fingers.

[0027] The extension and contraction mechanism of the traffic blocking device 11 of this embodiment does not have to be the pantograph 11b. For example, the traffic blocking device 11 may be one that is extended and contracted by a hydraulic syringe that extends and contracts in the vertical direction.

[0028] (Second embodiment of the traffic blocking device 11) 5A and 5B are explanatory diagrams of a second example of the traffic blocking device 11 in the mechanical parking device 10 of the first embodiment. Fig. 5A is a diagram of the traffic blocking device 11 protruding inside the exit route R, and Fig. 5B is a diagram of the traffic blocking device 11 retracted outside the exit route R. The blocking portion 11g of the traffic blocking device 11 in the second embodiment is a flat plate member that is thin enough for vehicles to drive over but does not interfere with 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 stand 5 is in the extended position, the traffic blocking device 11 rises from the floor of the boarding / de-boarding compartment 9 on the exit route R, blocking the exit route R. When the charging stand 5 is in the stored position, the motor lays the flat plate member down on the floor 9c of the boarding / de-boarding compartment 9. With this configuration, when the flat plate member of the traffic blocking device 11 is laid down, vehicles and people can pass over the flat plate member. Other configurations of the traffic blocking device 11 of the second embodiment are the same as those of the first embodiment.

[0029] (Third embodiment of the traffic blocking device 11) Fig. 6 is an explanatory diagram of a third example of the traffic blocking device 11 in the mechanical parking device 10 of the first embodiment. Fig. 6(A) is a diagram of the traffic blocking device 11 protruding inside the exit route R, and Fig. 6(B) is a diagram of the traffic blocking device 11 retracted outside the exit route R. The traffic blocking device 11 of the third embodiment differs from the first and second embodiments in that the barrier portion 11g protrudes from above toward the inside of the exit route R. The traffic blocking device 11 of the third embodiment may be, for example, a sign board 14 that repeatedly protrudes and retracts from the top of the entrance 9a by extending and retracting a pantograph 11b. The pantograph 11b may be covered with a cover 11e.

[0030] The display board 14 may be a signboard directly displaying instructions encouraging users to park the charging stand 5, or may be an electronic display board. The traffic blocking 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). This causes the traffic blocking device 11 to block the passage of the EV 1. To exit the parking lot without colliding with the traffic blocking device 11, the display board 14 must be retracted to the outside of the exit route R. When a user or the like manually returns the charging stand 5 to the stored position, the pantograph 11b retracts and moves to a position above the exit route R (for example, above the entrance 9a). This opens the exit route R, allowing the electric vehicle 1 to exit. Other configurations of the traffic blocking device 11 of the third embodiment are the same as those of the first embodiment.

[0031] (Fourth embodiment of the traffic blocking device 11) 7A and 7B are explanatory diagrams of a fourth example of the traffic blocking device 11 in the mechanical parking device 10 of the first embodiment. Fig. 7A is a diagram of the traffic blocking device 11 protruding inside the exit route R, and Fig. 7B is a diagram of the traffic blocking device 11 retracted outside the exit route R. The traffic blocking device 11 of the fourth embodiment also protrudes from above onto the exit route R. The traffic blocking device 11 of this embodiment has a structure in which a blocking unit 11g is attached to the tip of an L-shaped rotating arm 11f attached to the top of the entrance 9a. A display board 14 may be attached to the blocking unit 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 perpendicular to the wall surface above the entrance 9a and bends 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. When the rotating arm 11f is rotated by the driving of the actuator 11c, the display board 14 swings between the outside and inside of the delivery route R. The display board 14 may be a signboard on which a message to users is directly written, or it may be an electronic display board.

[0033] With this configuration, the traffic blocking device 11 of the fourth embodiment, even though it has a simple configuration, can protrude the barrier part 11g above the exit route R simply by rotating the rotating arm 11f, thereby blocking the passage of the electric vehicle 1. Other configurations of the traffic blocking device 11 of the fourth embodiment are the same as those of the third embodiment.

[0034] (Fifth embodiment of the traffic blocking device 11) Figure 8 is an explanatory diagram of a fifth example of the traffic blocking device 11 in the mechanical parking device 10 of the first embodiment. Figure 8(A) is a diagram of the traffic blocking device 11 protruding inside the exit route R, and Figure 8(B) is a diagram of the traffic blocking device 11 retracted outside the exit route R. The fifth embodiment of the traffic blocking device 11 is a movable bollard provided on the upper surface 3a of the pallet 3 in a range forward of the front wheels 1a of an electric vehicle 1 parked on the pallet. The traffic blocking device 11 of this embodiment includes a bollard portion 11j that protrudes from the upper surface 3a of the pallet 3 in a range forward of the front wheels 1a of an electric vehicle 1 parked on the pallet when the charging stand 5 is in the extended position, and an actuator 11h that moves the bollard 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 bollard portion 11j onto the pallet when the charging stand 5 is in the extended position. On the other hand, when the charging stand 5 is in the retracted position, the control device 13 retracts the bollard 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 bollard portion 11j as shown in this figure, or a hydraulic syringe that moves the bollard portion 11j up and down.

[0035] When the traffic blocking device 11 is the fifth embodiment, the user is prompted to store the charging stand 5 by audio guidance output from a speaker (not shown) or by the display board 14. This makes it possible to inform the user that the reason the car stopping block 11j is not retracted is that the charging stand 5 has not been stored, even if the car stopping block 11j is not visible from the driver's seat.

[0036] Fig. 9 is an explanatory diagram of a two-level mechanical parking system 10 employing a fifth example of the first embodiment. Fig. 9(A) is a front view of the two-level parking system 10. Fig. 9(B) is a perspective view of the entrance 9a as seen from the boarding / deboarding compartment 9. Note that Fig. 9(B) omits the illustration of the control device 13, the operating device 11h, and the partition 23. The mechanical parking device 10 of the fifth embodiment may be a two-level parking device. When the mechanical parking device 10 is a two-level parking device, the boarding and disembarking area on the first floor above ground where cars get in corresponds to the boarding and disembarking room 9 of this embodiment. In this example, the two-level parking device 10 is a ground-level three-level lift-and-traverse type that provides three levels (1F, 2F, 3F) of vehicle parking spaces in the same installation space.

[0037] In this example, of the three tiers, two pallets 3 located on the first floor can move horizontally, two pallets 3 located on the second floor can move horizontally and rise and fall, and three pallets 3 located on the third floor can only rise and fall. Therefore, in this example, the capacity of the vehicle 1 is 3×3−2=7 vehicles.

[0038] In this example, the triple-entrance, two-level parking device has three boarding and disembarking areas (boarding and disembarking compartments 9) in installation spaces A, B, and C. The overall width of the pallets 3 is preferably the same, but may be different. Note that each boarding and disembarking area in installation spaces A, B, and C is arranged so that the three pallets 3 are positioned adjacent to each other with a required gap (for example, 40 mm or less) between them.

[0039] The two pallets 3 located on the first floor have wheels 24a at both ends of their length, and are moved horizontally along two horizontal rails 19 installed on the first floor by a horizontal drive device (not shown), allowing the EV vehicle 1 to be directly loaded and unloaded from one of the boarding and disembarking compartments 9 in installation spaces A, B, and C.

[0040] The two pallets 3 located on the second floor have wheels 24b at both longitudinal ends of a rectangular frame 18 that hoists them. The rectangular frame 18 surrounds the pallet 3 parked on the intermediate level between the top and bottom levels, and is installed so that it can move laterally while suspending the pallet 3. With this configuration, the two pallets 3 located on the second floor are moved horizontally along horizontal rails 19 installed on the second floor by a horizontal drive device (not shown), allowing the electric vehicle 1 to be directly loaded and unloaded into one of the boarding and disembarking compartments 9 of installation spaces A, B, and C.

[0041] In this example, the two-tiered parking device 10 has a pallet 3 that can be raised and lowered to carry the EV vehicle 1 between the entry / exit height (FL) at which the EV vehicle 1 enters and exits, and a parking space above this entry / exit height. The pallets 3 that can be raised and lowered correspond to the two pallets 3 located on the second floor and the three pallets 3 located on the third floor.

[0042] In this example, the two-level parking device 10 further includes a lifting drive device 21 for lifting and lowering the pallet 3. The lifting drive device 21 winds up or unwinds a flexible string member 20 (chain or wire) that extends vertically at a position that does not interfere with the EV 1, and raises or lowers the lower end of the string member.

[0043] The lifting drive device 21 for the second floor is fixed to the rectangular frame 18 and moves horizontally together with the rectangular frame 18. The lifting drive device 21 for the third floor is fixed to the main body frame and is configured to lift and lower the three pallets 3 independently from the main body frame.

[0044] In addition, in this example, the lower ends of the four string members 20 are fixed to a total of four locations, at the front and back of the pallet 3, taking into account the load balance, and the lifting drive device 21 allows the pallet 3 to be raised and lowered while being kept horizontal.

[0045] As shown in Figure 9(A), the two-level parking system 10 of this embodiment is provided with an opening / closing door 9b that opens and closes an entrance 9a to the boarding / disembarking area on the first floor. The opening / closing door 9b is supported by door supports 22 that are erected vertically on both sides of the entrance 9a so that it can be raised and lowered. Partitions 23, such as fences or walls, are provided on the left and right sides and rear of the two-level parking device 10 to prevent people from entering the boarding / deboarding compartment 9 from any location other than the entrance 9a.

[0046] In the case of a two-level parking device 10 in which the entrance 9a opens when the opening / closing door 9b rises, the display board 14 may be attached to the boarding / alighting compartment side (pallet side) of the opening / closing door 9b as shown in Fig. 9(B). In this way, the display board 14 is raised at a high position when the opening / closing door 9b opens, so that the display board 14 can be seen by the user in the driver's seat, etc. Other configurations of the traffic blocking device 11 of the fifth embodiment are the same as those of the first embodiment.

[0047] Next, the operation of the mechanical parking device 10 with charging function of the first embodiment will be described. Fig. 10 shows the operation flow of the mechanical parking device 10 with charging function when entering the parking lot according to the first embodiment. As shown in Fig. 10, a user or the like 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 thereto.

[0048] When an operation signal instructing parking is input from the input device 15, the control device 13 of the mechanical parking device 10 moves the target empty pallet 3 from the storage shelf 4 to the boarding / deboarding room 9 and places it in the boarding section of the boarding / deboarding room 9. At this time, the control device 13 keeps the traffic blocking device 11 retracted into the retraction hole 11a. Then, the opening / closing door 9b opens.

[0049] The user drives the EV 1 into the boarding / disembarking area 9 through the entrance 9a and stops the vehicle on the pallet 3. The user then raises the charging stand 5 on the pallet 3 into a protruding position and connects the charging stand 5 to the power supply port of the EV 1 with the charging cable 5a. Next, the user or the like goes outside through the entrance 9a and inputs a command to the input device 15 to close the door 9b.

[0050] When the control device 13 receives an operation signal to close the opening / closing door 9b from the input device 15, it closes the opening / closing door 9b and stores the pallet 3 in the boarding area in an empty storage shelf 4. The rest of the entry flow of the mechanical parking device 10 of the present invention is the same as that of a normal mechanical parking device with a charging function.

[0051] Next, the operation at the time of leaving the parking lot will be described. Fig. 11 shows the operation flow at the time of leaving the parking lot of the mechanical parking device 10 with charging function of the first embodiment. When an operation signal instructing removal is input from the input device 15, the control device 13 of the mechanical parking device 10 pulls out the pallet 3 carrying the target EV 1 from the storage shelf 4, moves it to the boarding / deboarding room 9, and places it in the boarding area. At this time, the control device 13 starts detection by the monitoring device 7. The monitoring device 7 continuously outputs a position signal to the control device 13 indicating whether the charging stand 5 is in the extended position or the retracted position.

[0052] If the input attitude signal indicates that the charging stand 5 is in the protruding attitude, the control device 13 protrudes the traffic blocking device 11 to the inside of the exit route R and opens the opening / closing door 9b. Thereafter, the monitoring device 7 continues to detect the attitude of the charging stand 5. On the other hand, if the attitude signal indicates that the charging stand 5 is in the stored attitude, the control device 13 opens the opening and closing door 9b while keeping the traffic blocking device 11 retracted into the retraction hole 11a.

[0053] When the opening and closing door 9b opens, the user enters the boarding and disembarking compartment 9 and removes the charging cable 5a from the charging stand 5 and the EV 1. During this time, the mechanical parking device 10 continues to detect the position of the charging stand 5 using the monitoring device 7. When a user or the like stores the charging stand 5 in the storage room 5b, the monitoring device 7 detects this and outputs a position signal indicating that the charging stand 5 is in the stored position. When the control device 13 receives the position signal, the control device 13 controls the traffic blocking device 11 to move it away from the exit route R. This removes the obstacle (traffic blocking device 11) from the exit route R, opening the exit route R. The user or the like gets into the EV vehicle 1 and drives it out of the boarding / exiting room 9 through the entrance 9a to move the EV vehicle 1.

[0054] When the user exits through the entrance 9a, the user temporarily parks the car and operates the input device 15 to close the opening / closing door 9b. For example, if the input device 15 is a control panel attached to the outer wall of the mechanical parking device 10, the user temporarily gets out of the car and operates the control panel to close the opening / closing door 9b. If the input device 15 is a remote control or a smartphone, the user may operate it from the driver's seat to input an operation signal to the mechanical parking device 10. At this time, a confirmation message may be displayed on the operation screen of the operation panel or the screen of the smartphone to ask the user or the like whether or not the retraction of the charging stand 5 has been completed.

[0055] The control device 13 that has received the operation signal controls the mechanical parking device 10 to close the opening and closing door 9 b and store the pallet 3 in the storage shelf 4 .

[0056] In this way, when a user or the like forgets to put away the charging stand 5, the mechanical parking device 10 with charging function of this embodiment makes the traffic blocking device 11 appear on the exit route R to physically prevent the vehicle from leaving the boarding / disembarking compartment 9, thereby prompting the user or the like to put away the charging stand 5. When the mechanical parking device 10 with charging function confirms that the user or the like 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. In this way, the mechanical parking device 10 can reliably prevent users or the like from forgetting to put away the charging stand 5.

[0057] (Second embodiment) Figure 12 is an explanatory diagram of a mechanical parking device 10 with a charging function according to a second embodiment. Figure 12(A) is an explanatory diagram of a remote control, which is an input device 15 according to this embodiment. Figure 12(B) is an enlarged view of the charging stand 5 in the extended position, and Figure 12(C) is an enlarged view of the charging stand 5 in the stored position. In this embodiment, the mechanical parking device 10 does not store the charging stand 5 manually by a user or the like, but stores the charging stand 5 under the control of the control device 13, triggered by the output of an operation signal input by the user or the like to the input device 15. The mechanical parking device 10 with charging function in the second embodiment includes the input device 15 and a drive device 5c that drives the charging stand 5 between the extended position and the stored position. The control device 13 controls the drive device 5c in accordance with the operation signal input from the input device 15.

[0058] The input device 15 receives instructions from the user or the like for the control device 13 and outputs them as operation signals, and is, for example, a remote control or a smartphone with a dedicated app downloaded. The operation screen of the dedicated app or the remote control is provided with buttons for storing and standing up the charging stand 5, such as the "storage / standing up" button in Fig. 12(A). In this diagram, the "Call" button on the remote control is a button for calling the target pallet 3, and the "Open" and "Close" buttons are buttons for instructing the opening and closing of the opening and closing door 9b. The "Emergency Stop" button at the bottom is a button for urgently stopping the operation of the mechanical parking device 10.

[0059] As shown in FIGS. 12(B) and 12(C), the charging stand 5 of this embodiment is transformed between a protruding position and a retracted position by the driving of a driving device 5c such as a motor or a hydraulic syringe. With this configuration, in the mechanical parking device 10 of the second embodiment, when a user or the like presses or taps the "store / stand up" button, the mechanical parking device 10 itself performs the storage operation of the charging stand 5. In this respect, the mechanical parking device 10 of the second embodiment differs from the mechanical parking device 10 of the first embodiment, in which the user or the like manually moves 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 at the time of parking in this embodiment is the same as that in the first embodiment. FIG. 13 shows the operation flow of the mechanical parking device 10 with charging function of the second embodiment when it leaves the parking lot. The leaving operation of the mechanical parking device 10 with charging function of the second embodiment differs from that of the first embodiment in the following two points. First, the monitoring device 7 monitors the position of the charging stand 5 until the opening and closing door 9b is opened. Second, when a user presses or taps the "store / stand" button on the input device 15 to instruct the charging stand 5 to be stored, the operation signal output thereby triggers the retraction of the traffic blocking device 11 simultaneously with the retraction of the charging stand 5. In this case, the retraction of the charging stand 5 and the retraction of the traffic blocking device 11 may occur either first, or simultaneously.

[0061] After opening the entrance 9a, the control device 13 starts accepting an operation signal. When an operation signal to change the charging stand 5 to the stored position is input from the input device 15, the control device 13 controls the drive device 5c to change the charging stand 5 to the stored position. At the same time, the control device 13 controls the traffic blocking device 11 to open the exit route R.

[0062] In the mechanical parking device 10 of this embodiment, the trigger for starting storage of the charging stand 5 is pressing or tapping the "store / stand up" button, allowing for the user's decision to intervene. This prevents storage of the charging stand 5 from starting without instructions from the user, preventing a situation in which storage of the charging stand 5 starts before the charging cable 5a is disconnected.

[0063] Furthermore, when manually storing the charging stand 5, the user must bend down enough to touch the top surface 3a of the pallet 3 with their hands, which places a great burden on wheelchair users and physically disabled users working in that position. However, with the mechanical parking device 10 of the second embodiment, the charging stand 5 is stored by the mechanical parking device 10 itself, so there is no work that must be done near the top surface 3a of the pallet 3. Therefore, with the mechanical parking device 10 of this embodiment, wheelchair users and physically disabled users can park their EV 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) In the mechanical parking device 10 with charging function of the third embodiment, the boarding and disembarking room 9 is of a pass-through type. 14 is a plan view of the boarding / deboarding compartment 9 of a mechanical parking device 10 with a charging function according to the third embodiment. This figure illustrates a vertical elevator-type parking device. The mechanical parking device 10 of this embodiment is provided with an entrance 17 for use when entering the boarding / deboarding compartment 9, in addition to the exit entrance 9a.

[0065] In this boarding / deboarding room 9, an entrance door 17A is provided at an entrance 17 for entering the parking lot, which is separate from the exit entrance 9a. When the boarding / deboarding room 9 has an entrance 17 separate from the exit entrance 9a, the traffic blocking device 11 may be an opening / closing door 9b that opens and closes the exit entrance 9a. In other words, the opening / closing door 9b of the exit entrance 9a may be used as the traffic blocking device 11 that blocks the exit route R until it is determined that the charging stand 5 is in the stored position.

[0066] Next, the operation of the mechanical parking device 10 with charging function of the third embodiment will be described. When a user or the like enters the mechanical parking device 10 with charging function of the third embodiment, when the user or the like calls up the target pallet 3, the entrance door 17A opens while the exit entrance 9a remains closed, and the user or the like enters the boarding / exiting compartment 9 through the entrance 17. The user or the like parks the electric vehicle 1 on the pallet in the boarding area, places the charging stand 5 in a protruding position, and connects the charging stand 5 and the electric vehicle 1 with the charging cable 5a. The user or the like then exits the boarding / exiting compartment 9 and closes the entrance door 17A. The mechanical parking device 10 then stores the pallet 3 in the boarding area in the storage shelf 4.

[0067] FIG. 15 shows the operation flow of the mechanical parking device 10 with charging function of the third embodiment when leaving the parking lot. In the exit operation of the mechanical parking device 10 of the third embodiment, first, a user or the like calls out the target pallet 3, and the mechanical parking device 10 moves the pallet 3 to the boarding section of the boarding / exiting compartment 9. After that, the mechanical parking device 10 opens the entrance door 17A while keeping the opening / closing door 9b closed, and the monitoring device 7 begins detecting the posture of the charging stand 5. The user or the like enters the boarding / exiting compartment 9 through the entrance 17 with the opening door 17A. The control device 13 continues to keep the opening / closing door 9b closed as long as the charging stand 5 is in the protruding posture.

[0068] Next, when it is determined that the charging stand 5 will be in the stored position, the control device 13 opens the door 9b of the exit entrance 9a. "When it is determined that the charging stand 5 will be in the stored position" refers to when a position signal indicating that the charging stand 5 has been in the stored position is input, as in the first embodiment, or when an operation signal to change the charging stand 5 to the stored position is input, as in the second embodiment. The user then drives the EV 1 out of the boarding / disembarking compartment 9 through the open exit entrance 9a and performs an operation to close the door using the input device 15 of the mechanical parking device 10. This operation causes the mechanical parking device 10 to close the entrance door 17A of the entrance 17 and the opening / closing door 9b of the exit entrance 9a, and store the pallet 3 in the storage shelf 4.

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

[0070] (Fourth embodiment) 16 is a plan view of the boarding / deboarding room 9 of the mechanical parking device 10 with charging function of the fourth embodiment. The boarding / deboarding room 9 of this embodiment has an entrance 17 through which people can enter and exit, separate from the entrance 9a. A person door 17B is attached to the entrance 17. As in the third embodiment, even when the boarding / deboarding room 9 is provided with an entrance 17 separate from the passage 9a, the opening / closing door 9b of the passage 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. FIG. 17 shows the operation flow of the mechanical parking device 10 with charging function of the fourth embodiment when leaving the parking lot. In the leaving operation of the mechanical parking device 10 of this embodiment, first, a user or the like calls out the target pallet 3, and the mechanical parking device 10 moves the target pallet 3 to the boarding section of the boarding / deboarding space 9. After that, the mechanical parking device 10 unlocks the passenger door 17B while keeping the opening / closing door 9b of the entrance 9a closed, and invites the user or the like into the boarding / deboarding space 9 through the entrance 17. After that, the mechanical parking device 10 starts detecting the posture of the charging stand 5 using the monitoring device 7. The control device 13 continues to keep the opening / closing door 9b closed as long as the charging stand 5 is in the protruding posture.

[0072] Next, when it is determined that the charging stand 5 is in the stored position, the opening / closing door 9b at the entrance 9a is opened. Thereafter, the user or the like drives the EV 1 and leaves the boarding / de-boarding compartment 9 through the opened entrance 9a, temporarily parks the EV 1, and performs an operation to close the opening / closing door 9b using the input device 15. With this operation, the mechanical parking device 10 closes the opening / closing door 9b at the entrance 9a and stores the pallet 3 in the storage shelf 4. Other configurations, operations, and effects of this embodiment are the same as those of the third embodiment.

[0073] (Fifth embodiment) The mechanical parking device 10 of the fifth embodiment uses the opening and closing door 9b also as a traffic blocking device 11 by changing the degree to which the opening and closing door 9b is opened. The front view of the mechanical parking device 10 of the fifth embodiment is the same as that shown in Fig. 9(A). Fig. 18 is a perspective view showing a portion. More specifically, Fig. 18 is a perspective view of the ground floor 1F of the mechanical parking device 10 with charging function of the fifth embodiment shown in Fig. 9(A), viewed from the front of the mechanical parking device 10. This figure shows, as an example of the mechanical parking device 10, a two-level multi-level parking device in which the entrance 9a opens when the opening / closing door 9b rises.

[0074] Note that this diagram omits depiction of the second floor and above of the two-level parking system 10, the support pillars of the frame body, and the control device 13. It goes without saying that the mechanical parking system 10 of this embodiment can also be applied to mechanical parking systems other than two-level parking systems. In this two-level parking device 10, an entrance 9a leading to a boarding and disembarking area on the first floor above ground is opened and closed by a lift-up door 9b.

[0075] FIG. 18(A) is a diagram showing the opening and closing door 9b in a half-open state. As shown in this figure, in the exit operation of the two-level parking device 10 of this embodiment, when a user or the like calls the target pallet 3 to the boarding / disembarking area (boarding / disembarking compartment 9), the control device 13 opens the opening door 9b to a half-open state. In the present invention, the "half-open state" refers to a state (degree of opening of the opening door 9b) in which the opening door 9b is open so that the entrance 9a is large enough for a person to pass through but not for an electric vehicle 1. In the example shown in this figure, the bottom of the opening door 9b is lower than the height of the roof of the electric vehicle 1, but the opening door 9b of the entrance 9a is opened to a height that allows a user or the like to pass through the opening door 9b by bending down, thereby maintaining the opening door 9b in a half-open state.

[0076] By setting the opening / closing door 9b in a half-open state, users and the like can enter the boarding / deboarding room 9 through the opening / closing door 9b. In addition, the passage entrance 9a opened below the opening / closing door 9b is not yet open enough for the electric vehicle 1 to pass through, so the opening / closing door 9b can block the exit route R of the electric vehicle 1. In other words, the opening / closing door 9b in the half-open state in this figure can be said to be an access blocking device 11 that protrudes from above the exit route R to 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 an access blocking device 11 even if the boarding / deboarding room 9 does not have an entrance separate from the passage entrance 9a as in the third and fourth embodiments. Next, after the opening / closing door 9b is set to a half-open state, the control device 13 prompts users and the like to store the charging stand 5 by means of a display board 14 provided on the boarding / exiting compartment side of the opening / closing door 9b and by means of audio guidance played from a speaker (not shown).

[0077] FIG. 18(B) shows the state when the opening and closing door 9b is fully open. When a user or the like stores the charging stand 5, the control device 13 detects this using the monitoring device 7 (not shown) and fully opens the opening / closing door 9b. As a result, the opening / closing door 9b, which is the traffic blocking device 11, retreats to the outside of the exit route R (above the exit route R), opening the exit route R. The user or the like then drives the EV 1 to exit the boarding / deboarding compartment 9 through the opened entrance 9a, parks the EV 1, and performs an operation to close the opening / closing door 9b using the input device 15. With this operation, the two-level parking device 10 closes the opening / closing door 9b at the entrance 9a and stores the pallet 3 in the storage shelf 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 opening and closing door 9b is opened and closed by lifting and lowering, but this embodiment can also be used in a mechanical parking device 10 in which the opening and closing door 9b is opened and closed by lateral movement. In this case, the "half-open state" refers to a state in which the opening and closing door 9b is open to an extent that the width of the open passage 9a is smaller than the width of the electric vehicle 1, but is wide enough for users and the like to pass through. The configuration, operation, and effects of the opening and closing door 9b when it is opened and closed by lateral movement are the same as those of the opening and closing door 9b when it is opened and closed by lifting and lowering as described above.

[0079] (Sixth embodiment) The mechanical parking device 10 of the sixth embodiment is a two-level parking device in which an entrance 9a opens when an opening / closing door 9b descends underground. Figure 19 is a perspective view showing a part of the first floor above ground of the mechanical parking device 10 with charging function of the sixth embodiment. Figure 19(A) is a perspective view of the two-level parking device 10 as seen from the outside.

[0080] This figure shows an example of a two-tiered, three-tier, lift-and-transport type above ground parking device 10, which has three tiers (1F, 2F, 3F) of vehicle parking spaces in the same installation space. In this example, of the three tiers, four pallets 3 located on the 1st floor can move horizontally and transversely, four pallets 3 located on the 2nd floor can move transversely and ascend and descend, and five pallets 3 located on the 3rd floor can only ascend and descend. Therefore, in this example, the capacity of the vehicle 1 is 3×5−2=13.

[0081] 19(B) is a perspective view of the entrance 9a seen from inside the boarding / exiting compartment 9 of the two-level parking system 10. In this figure, the support pillars of the frame body of the two-level parking system 10, the control device 13, and the partition 23 are omitted. The opening / closing door 9b in this embodiment is supported by a vertically erected door support pillar 22 so as to be able to move up and down between the first floor above ground and the basement. The barrier portion 11g of the traffic blocking device 11 in this embodiment is a plate-like or rod-like member provided on the back side (the boarding / de-boarding compartment side) of the door support pillar 22. This barrier portion 11g is rotatable between a vertical position overlapping the door support pillar 22 and a horizontal position protruding into the exit route R. The actuator 11h that rotates the barrier portion 11g may be, for example, a motor. With this configuration, the traffic blocking device 11 in this embodiment can protrude from the side of the exit route R to the inside thereof. Furthermore, the length of the barrier portion 11g is preferably shorter than two-thirds and longer than one-third of the width of the entrance 9a. This allows users and others to avoid the barrier portion 11g and enter the boarding / de-boarding compartment 9 even when the barrier portion 11g protrudes into the exit route R.

[0082] Although a traffic blocking device 11 may be provided on all door support posts 22, it is preferable that a traffic blocking device 11 be provided on every other door support post 22. When a traffic blocking device 11 is provided on every other door support post 22, one end of the traffic blocking device 11 can rotate either clockwise or counterclockwise so as to protrude into either the left or right boarding / deboarding compartment 9. This allows one traffic blocking device 11 to be used for both the left and right boarding / deboarding compartments 9, thereby reducing the number of traffic blocking devices 11 to be installed.

[0083] 20 is an explanatory diagram of the operation of the mechanical parking device 10 with charging function of the sixth embodiment when leaving the parking lot. This figure is also a perspective view of the entrance 9a seen from inside the boarding / deboarding compartment 9 of the two-level parking device 10. In addition, in this figure, the illustration of the support pillars of the frame body of the two-level parking device 10, the control device 13, and the partition 23 is omitted.

[0084] In the exit operation of the two-level parking device 10 of this embodiment, first, a user or the like calls the target pallet 3 to the boarding / deboarding area (boarding / deboarding compartment 9) on the first floor above ground. The control device 13 rotates the blocking portion 11g of the traffic blocking device 11 toward the boarding / deboarding compartment 9 where the called pallet 3 is to be placed, causing the traffic blocking device 11 to protrude into the entrance 9a. Next, the opening / closing door 9b is opened. The opening / closing door 9b descends into the underground space, and the entrance 9a opens (FIG. 20(A)). This allows the user or the like to avoid the traffic blocking device 11 and enter the boarding / deboarding compartment 9 through the entrance 9a. Note that a message prohibiting anyone other than the driver from entering the boarding / deboarding compartment 9 may be printed on the front side of the traffic blocking device 11 (the front side of the two-level parking device 10).

[0085] The traffic blocking device 11 projects the other end from the door support pillar 22 toward the entrance 9a, thereby projecting inward of the exit route R and blocking the passage of the electric vehicle 1. It is preferable that a display board 14 is provided on the pallet side of the traffic blocking device 11 (the rear side of the two-level parking device 10) to display a message encouraging the user to store the charging stand 5. This allows the message encouraging the user to store the charging stand 5 to be visible to the user in the driver's seat when the traffic blocking device 11 protrudes into the entrance 9a.

[0086] When the user or the like stores the charging stand 5, the control device 13 detects this with the monitoring device 7 (not shown) and rotates the traffic blocking device 11 until it is vertical (i.e., until it overlaps with the door support pillar 22). This causes the traffic blocking device 11 to retract to the outside of the exit route R, opening the exit route R. The user or the like then drives the EV 1 to exit the boarding / exiting room 9 through the entrance 9a, parks the EV 1, and closes the opening / closing door 9b using the input device 15. In this way, the traffic blocking device 11 of the present invention can also be used in a two-level parking device 10 in which the entrance 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 the extended position when leaving the parking lot, the traffic blocking device 11 protrudes inside the exit route R to block the passage of the EV 1, and once it is confirmed that the charging stand 5 is in the stored position, the traffic blocking device 11 retracts outside the exit route R. In this way, the mechanical parking device 10 with charging function of the present invention allows the user who has used the charging stand 5 to retract the charging stand 5 reliably when leaving the parking lot.

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

[0089] Furthermore, since the traffic blocking device 11 blocks the exit route R so that the EV 1 cannot pass through, even if the EV 1 makes an erroneous start, it can be prevented from flying out of the mechanical parking device 10.

[0090] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0091] (1) The mechanical parking device 10 may have two boarding / deboarding compartments 9, one for entering and one for leaving. In that case, the traffic blocking device 11 is not installed in the boarding / deboarding compartment 9 for entering, but is installed only in the boarding / deboarding compartment 9 for leaving. The other configurations, operations, and effects of this embodiment are the same as those of the first to fourth embodiments.

[0092] (2) All of the pallets of the mechanical parking device 10 may be charging pallets 3, or some of them may be charging pallets 3. If the charging pallets 3 are part of the pallets provided in the mechanical parking device 10, the pallets 3 are placed in the boarding / disembarking compartment 9 when a user of the EV vehicle 1 or the like calls the pallet.

[0093] (3) In the unlikely event that the monitoring device 7 malfunctions, the traffic blocking device 11 may not be extended when the vehicle leaves the parking lot, and instead a message may be displayed on the operation screen of the control panel or on the smartphone of the user, etc., to confirm that the charging stand 5 has been stored.
