Description

  The present invention relates to a mechanical parking lot.

  In recent years, development of vehicles that run using electric power stored in a rechargeable battery has been promoted. For example, electric power supplied from the outside is stored in a rechargeable battery, and electric power stored in the rechargeable battery is supplied to a motor. As a result, vehicles that travel are being developed.

  Correspondingly, even in a parking lot where the vehicle is parked, it is required to have a facility for supplying charging power to the vehicle at the time of parking. Practical application is under consideration.

  In particular, in a mechanical parking lot such as a vertical circulation system, a multi-layer circulation system, a horizontal circulation system, an elevator system, a plane reciprocation system, a two-stage system or a multistage system, the vehicle is placed on a pallet or the like. In such a case, a technique for supplying electric power to a parked vehicle has been proposed (see, for example, Patent Documents 1 to 4). .

Japanese Patent No. 2789062 Japanese Patent No. 2908939 Japanese Patent No. 2908940 Japanese Utility Model Publication No. 06-028124

  In the above-described Patent Documents 1 to 4, a technology for supplying electric power to a parked vehicle in a mechanical parking lot in which a pallet on which a vehicle is placed on the upper surface moves in the field has been proposed. In addition, a technique is described in which a connecting portion for relay that can be contacted and separated and used for power supply is provided in each storage space in which the pallet is stored.

By the way, since the pallet is taken out and stored from the storage space at the time of entering and leaving the vehicle, and also at the time of loading to optimize the arrangement of the parked vehicle in the parking lot, the above-mentioned relay connection portion Frequently repeat contact and separation.
As described above, when the relay connection portion contacts or separates, if power is supplied, a spark may occur between the relay connection portions. When a spark occurs, there is a problem that the relay connection part and its surrounding components are deteriorated due to the heat.
Similarly, if the contact portion does not reliably come into contact during storage, a similar problem occurs because a spark occurs on the contact surface during energization.

  Furthermore, the relay connection portion in the storage space from which the pallet is taken out is exposed to the outside. Since the connecting portion for relay provided in the storage space is electrically connected to the facility for supplying power, there is a problem that the exposed connecting portion for relay and the conductor may be short-circuited, and maintenance work is performed. There was a problem that there was a risk of electric shock when touched by an employee.

  The present invention has been made to solve the above-described problems, and prevents the occurrence of sparks in an electrical connection portion to prevent the deterioration of the connection portion, and also prevents a short circuit and an electric shock in the connection portion. The purpose is to provide a mechanical parking lot.

In order to achieve the above object, the present invention provides the following means.
The mechanical parking lot of the present invention is used for parking a vehicle that travels using at least the electric power stored in the rechargeable battery and is equipped with a charger that charges the rechargeable battery, and charges the vehicle with electric power. It is a mechanical parking device that is not provided with a charger that can move between a plurality of parking shelves for storing the vehicle, a warehousing unit where at least the vehicle is stored, and the plurality of parking shelves And a pallet having a supply end electrically connected to the vehicle mounted on the upper surface, a pallet-side connection portion disposed on the pallet and electrically connected to the supply end, and the parking shelf When the pallet is stored in the parking shelf, the parking shelf-side connecting portion electrically connected to the pallet-side connecting portion, and the plurality of parking shelf-side connecting portions, respectively, individually with conductors Connected With the conductive Te, a power supply unit for supplying power to the vehicle, after the pallet loaded with the vehicle stored in the parking shelf, on the stored the vehicle, from the power supply unit And a control unit for starting the supply of electric power.

According to the present invention, after the pallet on which the vehicle is placed is stored in the parking shelf and the pallet side connecting portion and the parking shelf side connecting portion are in electrical contact, the supply of power to the vehicle is started from the power supply portion. The Therefore, when the pallet-side connection portion and the parking shelf-side connection portion are in electrical contact, it is possible to prevent the occurrence of sparks, and it is possible to prevent the connection end from being deteriorated due to the sparks .

  Furthermore, since electric power is supplied after the pallet side connection part and the parking shelf side connection part are electrically connected, electric power is not supplied to the parking side connection part exposed to the outside. Therefore, it is possible to prevent a short circuit at the parking shelf side connection portion.

  In the said invention, the said pallet side connection part is provided in the lower surface of the said pallet, and the said parking shelf side connection part is in the position facing the said pallet side connection part when the said pallet in the said parking shelf is stored. One of the pallet side connection part and the parking shelf side connection part is provided with a conductive part that extends along the movement direction of the pallet when stored in the parking shelf and has conductivity. And, on the other hand, a conductive current collector, and a link portion that supports the current collector so as to be movable in a direction in which the current collector is moved toward and away from the current-carrying portion, and urges the current collector toward the current-carrying portion. It is desirable to be provided.

  According to the present invention, when the pallet is stored in the parking shelf, the current collector is pressed against the energization unit by the link unit, so that energization is possible between the pallet side connection unit and the parking shelf side connection unit. On the other hand, by removing the pallet from the parking shelf, the pallet side connecting portion and the parking shelf side connecting portion can be separated.

  Even if the deflection of the pallet is deformed downward due to the weight of the vehicle, the deflection is absorbed by the link portion, and the contact between the energization portion and the current collector can be easily maintained. Therefore, it is possible to easily ensure energization between the pallet side connection portion and the parking shelf side connection portion.

Since the energizing part extends in the moving direction of the pallet, the contact between the energizing part and the current collector can be easily maintained even when the storage position of the pallet stored in the parking shelf moves within a predetermined range. The energization between the pallet side connection part and the parking shelf side connection part can be easily ensured.
In other words, it is not necessary to accurately fix the storage position of the pallet with respect to the parking shelf in order to ensure energization between the pallet side connecting portion and the parking shelf side connecting portion.

In the above invention, at least a mechanical parking device used for parking a vehicle that travels using electric power stored in a rechargeable battery and is provided with a charger that charges the rechargeable battery, wherein the vehicle is It is movable between a plurality of parking shelves to be stored, at least a warehousing section where the vehicle is stored, and the plurality of parking shelves, and is electrically connected to the vehicle placed on the upper surface. A pallet having a supply end, a pallet-side connecting portion that is disposed on the pallet and is electrically connected to the supply end, and disposed on the parking shelf, and the pallet is stored in the parking shelf. A parking shelf side connecting portion that is electrically connected to the side connecting portion, a power supply portion that is electrically connected to the parking shelf side connecting portion and supplies power to the vehicle, and the pallet on which the vehicle is mounted. After the bets have been stored in the parking shelf, on the stored the vehicle, and a control unit for starting the supply of power from the power supply unit, is provided on the pallet side connecting portion, said supply A pallet-side conductor portion that is electrically connected to the end is provided, and the parking shelf-side connection portion includes a parking shelf-side conductor portion that is electrically connected to the power supply portion, and at least the parking shelf-side conductor portion is connected to the pallet-side conductor. A support portion that is movably supported toward the portion, and a biasing portion that biases the parking shelf side conductor portion toward the pallet side conductor portion, and the pallet is stored in the parking shelf. In this case, it is preferable that at least one of the pallet and the vehicle shelf is provided with a suction portion that generates a force that reduces the distance between the pallet-side connection portion and the parking shelf-side connection portion.

According to this invention, if a pallet is stored in a parking shelf, a pallet side connection part and a parking shelf side connection part will approach by a suction part. And since a parking shelf side conductor part is pressed against a pallet side conductor part by an energizing part, electricity supply becomes possible between a pallet side connection part and a parking shelf side connection part.
On the other hand, when the pallet is taken out from the parking shelf beyond the distance that the parking shelf side conductor can move, the pallet side connecting portion and the parking shelf side connecting portion are separated from each other.

Furthermore, even if an external force acts on the pallet stored in the parking shelf and the pallet moves in a direction in which the pallet side connection portion and the parking shelf side connection portion are separated from each other, the pallet is separated from the pallet side connection portion and parked by the suction portion. Since the shelf side connection portion is drawn in the approaching direction, energization between the pallet side connection portion and the parking shelf side connection portion is ensured.
On the other hand, when the pallet is taken out from the parking shelf, the pallet is taken out with a force larger than the force generated by the suction part, so that the pallet taking-out is not affected.

  By providing the support part and the biasing part in the parking shelf side connection part, the pallet side connection part does not protrude from the pallet. Therefore, when the pallet moves between the warehousing unit and the plurality of parking shelves, the pallet-side connecting unit is prevented from coming into contact with a structural member that constitutes another pallet, a parking shelf, or the like.

  In the above-described invention, the plurality of parking shelves are provided with a first parking shelf provided with the parking shelf-side connection portion and a second parking shelf other than the first parking shelf, and the control unit is connected to the rechargeable battery. The charging attribute is given to the vehicle that performs the charging of the vehicle, and the vehicle having the charging attribute is stored in the first parking shelf when the warehousing call of the vehicle having the charging attribute is made. It is desirable.

  According to the present invention, by storing the vehicle to be charged in the first parking shelf, the vehicle can be charged at the same time as being stored.

In the above invention, the pallet is provided with a first pallet provided with the pallet side connection portion and the supply end, and another second pallet, and at least one of the plurality of parking shelves. Is an empty parking shelf in which the pallet is not stored, and in a range where the total number of the first pallet, the second pallet, and the empty shelf is the total number of the parking shelves, than the number of the first parking shelves. It is desirable that the number of the first pallets is large.

  According to the present invention, a vehicle that has been placed on the first pallet and stored in the first parking shelf and has been charged is stored in the empty parking shelf together with the first pallet, and another vehicle that needs to be charged is loaded. The first pallet can be stored in an empty first parking shelf. In other words, the first pallet on which the vehicle waiting for charging is placed can be sequentially conveyed to the first parking shelf.

  In the above invention, the mechanical parking lot of the present invention for managing the stored vehicle based on the identification information corresponding to the vehicle, wherein the control unit is charged for each identification information or It is desirable to manage at least one of the times.

  According to the present invention, charging can be performed based on the number of times of charging and the time of charging, and there is no need to provide a measuring device for measuring the charged power.

  In the above invention, when the control unit is switched to the maintenance work mode and the first parking shelf storing the first pallet is selected, the selected first parking shelf is selected. It is desirable to supply electric power to the supply end of the first pallet stored in the container.

  According to the present invention, since electric power can be obtained from the supply end of the first pallet stored in the selected first parking shelf regardless of the presence or absence of the vehicle, when performing maintenance work in the mechanical parking lot. The power tool can be used easily.

  For example, when maintenance work using an electric tool is performed when power cannot be obtained from the supply end, it is necessary to obtain power through an extension cord from a power outlet located at a remote position, and the maintenance work is facilitated. I couldn't. In particular, in a mechanical parking lot such as an elevator system in which parking racks are arranged in the vertical direction, it is necessary to extend the extension cord in the vertical direction, and the work cannot be easily performed.

  On the other hand, by supplying electric power from the supply end of the first pallet closest to the place where the maintenance work is performed, it is not necessary to extend the extension cord over a long distance, and the maintenance work can be easily performed.

  In the above invention, a connection detection unit is provided for detecting whether or not the supply end is electrically connected to the vehicle, and the control unit parks the vehicle on the pallet together with the pallet. When starting the warehousing process stored in the shelf, it is desirable to issue an alarm based on the connection signal input from the connection detection unit.

According to the present invention, when a vehicle is stored in a parking shelf, the vehicle can be reliably charged.
That is, when the vehicle is placed on the pallet and the warehousing process of storing in the parking shelf is started, if the supply end is not electrically connected to the vehicle, an alarm is issued from the control unit. Therefore, the vehicle and the pallet are not stored in the parking rack while the supply end is not electrically connected to the vehicle.

  Furthermore, since the supply end was not connected to the vehicle at the time of warehousing, it is possible to prevent the situation where the vehicle cannot be used due to insufficient charging when the vehicle is unloaded.

Further, since the control unit issues an alarm when starting the warehousing process, the supply end can be easily connected to the vehicle.
For example, in the method of issuing an alarm after storing a vehicle and a pallet in a parking shelf, a manager of a mechanical parking lot or a driver of the vehicle can easily approach the vehicle stored in the parking shelf. Therefore, the presence or absence of connection between the supply end and the vehicle cannot be visually confirmed. Furthermore, the supply end cannot be connected to the vehicle.

Moreover, after storing a vehicle in a parking shelf, the driver | operator of a vehicle etc. has already left the mechanical parking lot in many cases. Then, even if the vehicle is returned to the entry section or the like, the driver or the like of the vehicle needs to connect the supply end to the vehicle, and the supply end may not be electrically connected to the vehicle.
Furthermore, since the vehicle is in the entry section, other users cannot park the electric vehicle or the conventional vehicle in the mechanical parking lot.

  Here, when starting the warehousing process, the driver of the warehousing vehicle, etc. goes out of the warehousing section and presses the “close” button to close the entrance door provided in the warehousing section. It can be illustrated. Furthermore, in addition to the above-mentioned “close” button, it may be the timing at which the “entry start” button, the “start” button, the “start” button, or the like, which is a button for starting the warehousing work, It is not limited.

It is desirable to issue an alarm based on at least one of the time signals.

  According to the present invention, since the vehicle can be prevented from descending from the pallet in a state where the supply end is electrically connected to the vehicle, it is possible to prevent the supply end and the vehicle from being damaged.

  Specifically, when the stop position of the vehicle placed on the pallet is moved and the supply end is connected to the vehicle, the control unit warns that the supply end remains connected to the vehicle. To emit. Alternatively, when a predetermined time has elapsed since the vehicle can descend from the pallet, and the supply end is connected to the vehicle, the control unit keeps the supply end connected to the vehicle. A warning to that effect is issued.

  By doing so, the vehicle can be mechanically parked by connecting the connection end, damaging the vehicle or the charging facilities of the mechanical parking lot, or being pulled by the connection end and hindering the driving of the vehicle. It is possible to prevent contact with facilities in the parking lot.

The link part 44 includes a fixed part 47D attached to the shelf body 41, a support part 47U attached to the current collector 43, a pair of arm parts 48 disposed between the fixed part 47D and the support part 47U, and a current collector. 43 and a spring 49 disposed between the fixing portion 47D and the fixing portion 47D.

  The fixing portion 47 </ b> D is a columnar member that extends from the upper surface of the shelf body 41 toward the trolley overhead wire 34, and supports the entire link portion 44.

  The support portion 47U is a columnar member extending downward from the current collector 43, and the current collector 43 can be rotated around a connection portion between the support portion 47U and the current collector 43 (within the plane of FIG. 7). It can be supported).

The arm portion 48 is a member for connecting the fixed portion 47D and the support portion 47U, and the support portion 47U can be moved closer to and away from the trolley overhead wire 34 with respect to the fixed portion 47D (in the vertical direction in FIG. 7). It is supported by (movable).
Specifically, the pair of arm portions 48 are arranged in parallel, and ends of the pair of arm portions 48 on the fixed portion 47D side are rotatably connected to the fixed portion 47D, and the support portion. The end portion on the 47U side is rotatably connected to the support portion 47U.

The spring 49 biases the current collector 43 in a direction approaching the trolley overhead line 34 (upward direction in FIG. 7).
Specifically, one end portion of the spring 49 is attached to the fixing portion 47 </ b> D, and the other end portion is attached to the current collector 43. Further, the spring 49 urges the current collector 43 in a direction that narrows the distance between the fixed portion 47 </ b> D and the current collector 43. As described above, when the current collector 43 is biased in the direction of narrowing the distance between the fixed portion 47D and the current collector 43, the pair of arm portions 48 rotate about the attachment portion with the fixed portion 47D. The current collector 43 moves upward.

The boarding part 5 is used when an electric vehicle or a conventional vehicle enters the mechanical parking lot 1 or when an electric vehicle or a conventional vehicle leaves the mechanical parking lot 1. As shown in FIG. 1, the entry portion 5 is disposed at the approximate center of the lower end of the building 2, in other words, at the lower end of the lift 6.
The boarding unit 5 is provided with a turning unit 51, an electrical contact 52, and a position detection unit 53.

  The turning unit 51 changes the direction of the electric vehicle or the conventional vehicle placed thereon by changing the direction of the EV pallet 3E or the conventional pallet 3C. By doing in this way, an electric vehicle and the conventional vehicle can enter or leave the mechanical parking lot 1 only by moving forward.

The electrical contact 52 is electrically connected to the trolley overhead wire 34 of the EV pallet 3E disposed in the entry portion 5, and may be the above-described current collecting arm 42 or other types. There is no particular limitation.
In the case of the present embodiment, description will be made by applying to an example in which the electrical contact 52 is arranged on the upper surface of the swivel unit 51 at a position facing the trolley overhead wire 34 of the EV pallet 3E.

In addition, when the turning part 51 is not provided in the boarding part 5, the electrical contact 52 may be provided in the floor surface of the boarding part 5, and it does not specifically limit.
Further, when the current collecting arm 42 is used as the electrical contact 52, the current collecting arm 42 is disposed on the lift 6 carrying device, and when the EV pallet 3E is slid and taken into the lift 6 carrying device, It may be electrically connected and is not particularly limited.

The position detection unit 53 is a sensor that detects a change in the stop position of the electric vehicle mounted on the EV pallet 3E.
The position detection unit 53 is a light-shielding photoelectric sensor arranged between the EV pallet 3E arranged in the entry unit 5 and the entrance door of the entry unit 5, and the optical axis of the photoelectric sensor is that of the electric vehicle. It is arranged so as to extend in a direction crossing the traveling direction.
The position detection unit 53 is connected so that a detection signal is input to the control unit 10.

Note that the control unit 10 or the position detection unit 53 detects only movement of a vehicle such as an electric vehicle when the vehicle continuously blocks the optical axis of the photoelectric sensor for a predetermined period or longer, that is, the light is blocked. If the vehicle stops, it is determined that the stop position of the vehicle has changed.
For this reason, even when the driver crosses the optical axis of the photoelectric sensor, the period during which the optical axis of the photoelectric sensor is blocked is less than the predetermined period described above. There is no judgment that it has changed.

  The lift 6 moves the EV pallet 3E and the conventional pallet 3C in the vertical direction between the predetermined EV parking shelf 4E and the conventional parking shelf 4C and the entry portion 5. At this time, the electric vehicle or the conventional vehicle may or may not be placed on the EV pallet 3E or the conventional pallet 3C.

As shown in FIG. 1, the control unit 10 controls the storage and removal of the EV pallet 3 </ b> E and the conventional pallet 3 </ b> C from the EV parking shelf 4 </ b> E and the conventional parking shelf 4 </ b> C.
Further, the control unit 10 controls charging of the electric vehicle by controlling the power supply unit 14 and charging by controlling the voice guidance unit 15V, the alarm buzzer unit 15B, the display lamp unit 15L, and the like. It also prevents problems related to work.
Details of the control by the control unit will be described later.

As shown in FIG. 1, the connection detection unit 11 confirms the connection between the electric vehicle and the supply cable 33 in the entry unit 5.
The connection detection unit 11 is electrically connected to a current collecting arm 42 disposed in the turning unit 51 and is connected to the control unit 10 so that signals can be transmitted.

The timer unit 12 measures an elapsed time after the EV pallet 3E on which the electric vehicle is mounted arrives at the entry unit 5 and the entrance door opens.
A signal notifying that the entrance door of the boarding unit 5 is opened is input from the control unit 10 to the timer unit 12, and a predetermined period of time has elapsed from the timer unit 12 to the control unit 10 after the entrance door is opened. A signal indicating that the time has elapsed is output.

As shown in FIG. 1, the power supply unit 14 supplies power to the EV parking rack 4 </ b> E, and controls supply and stop of power.
Power is supplied from the power supply 13 to the power supply unit 14, and power is supplied from the power supply unit 14 to the current collecting arm 42 of the EV parking shelf 4 </ b> E.

  The power source 13 supplies power for charging the electric vehicle and power for driving the lift 6 and the turning unit 51.

The voice guidance unit 15V, the alarm buzzer unit 15B, and the display lamp unit 15L issue a warning to the manager of the mechanical parking lot 1, the driver of the electric vehicle, and the like.
That is, when storage of the electric vehicle and the EV pallet 3E from the entry unit 5 to the EV parking shelf 4E is started, the electric vehicle is connected to the electric vehicle when the supply cable 33 is not connected. A warning is issued when attempting to get off the EV pallet 3E.

  That is, the voice guidance unit 15V issues a warning by voice in the above case, the alarm buzzer unit 15B issues a warning by the buzzer in the above case, and the display lamp unit 15L has the above case. A warning is issued by turning on the lamp.

Next, parking of a conventional vehicle and parking and charging of an electric vehicle in the mechanical parking lot 1 having the above configuration will be described.
8 to 10 are flowcharts illustrating the control in the control unit of FIG.
When storing a conventional vehicle or an electric vehicle in the mechanical parking lot 1, first, as shown in FIGS. 1 and 8, a personal identification number assigned to the conventional vehicle or the electric vehicle to be stored in the control unit 10. Such identification information is input (step S1).

  In the present embodiment, it is applied when a parking lot is used for a long time, such as a parking lot attached to an apartment, and a personal identification number for identifying each vehicle is assigned to each vehicle. explain.

  In addition, as a means to identify each vehicle, the method which inputs the PIN code assigned to each vehicle to the control part 10 as mentioned above may be sufficient, and when using the mechanical parking lot 1, a remote controller is used. In the case of using an IC card, each vehicle may be identified by identifying the remote controller or the IC card, and is not particularly limited.

Based on the input code number, the control unit 10 determines whether the vehicle to be stored is a conventional vehicle or an electric vehicle, in other words, whether the vehicle needs charging ( Step S2).
That is, as described above, when a personal identification number is assigned to each vehicle, the control unit 10 calls the attribute of the vehicle corresponding to the input personal identification number, and whether or not a charging attribute is given to the attribute. Whether the vehicle to which the personal identification number is assigned is a conventional vehicle or an electric vehicle is determined. Here, the attribute of the vehicle to be called is stored in the control unit 10 in advance.

  In addition, the mechanical parking lot 1 is where an unspecified vehicle is parked in units of time, a dark place number is not assigned to each vehicle, and the attributes of the vehicle are stored in the control unit 10 in advance. If not, for example, the manager of the parking lot may determine whether the vehicle to be stored is a conventional vehicle or an electric vehicle, and may input the determination result to the control unit 10. It is not limited.

When determining that the vehicle to be stored is an electric vehicle, the control unit 10 selects the EV pallet 3E on which the electric vehicle or the conventional vehicle is not mounted (step S3-1).
Then, the selected EV pallet 3E is taken out from the EV parking shelf 4E or the conventional parking shelf 4C stored so far (step S4-1).

  Specifically, first, the lift 6 is raised by the control unit 10 to a position adjacent to the EV parking shelf 4E storing the selected EV pallet 3E or the conventional parking shelf 4C. The selected EV pallet 3E is slid onto the lift 6, and the EV pallet 3E is placed on the lift 6.

  The lift 6 is lowered to the loading section 5 with the selected EV pallet 3E placed thereon, and the EV pallet 3E arrives at the loading section 5. Then, the entrance door of the boarding part 5 is opened (step S5-1).

A user who uses the mechanical parking lot drives an electric vehicle to be stored, enters the entry portion 5 while moving forward, and places the vehicle on the EV pallet 3E. When the user moves the electric vehicle to the stop position on the EV pallet 3E, the user parks the electric vehicle on the EV pallet 3E and gets off the electric vehicle (step S6-1).
As shown in FIG. 9, the user getting off the electric vehicle connects the supply cable 33 of the EV pallet 3E to the electric vehicle (step S7-1).

  Thereafter, the user goes out of the entrance section 5 and presses the “door close” button for closing the entrance door of the entrance section 5 to instruct the control section 10 to close the entrance door and start the storing operation. Input (step S8-1).

In the present embodiment, an example in which an instruction to close the entrance door and start the operation of storing the electric vehicle of the entry unit 5 in the EV parking shelf 4E is input to the control unit 10 by pressing the “door close” button. However, the instruction may be input by other methods and is not particularly limited.
For example, the above-described instruction may be input to the control unit 10 by pressing a “start warehousing” button, a “start” button, or a “start” button that starts warehousing of the vehicle.

  When the “door closed” button is pressed, the control unit 10 closes the entrance door of the boarding unit 5 and starts a series of operations related to storing the electric vehicle (step S <b> 9-1).

  First, the control unit 10 confirms whether or not the supply cable 33 is connected to the electric vehicle via the connection detection unit 11.

  That is, the trolley overhead wire 34 of the EV pallet 3 </ b> E electrically connected to the supply cable 33 is electrically connected to the electrical contact 52 of the entry portion 5 when the EV pallet 3 </ b> E is disposed in the entry portion 5. ing. Since the electrical contact 52 is electrically connected to the connection detection unit 11, when the electric vehicle is connected to the supply cable 33, the electric vehicle and the connection detection unit 11 are electrically connected. It will be.

  If communication such as a control signal is possible with the charger of the electric vehicle or the like, the connection detection unit 11 determines whether or not a line related to communication such as the control signal is electrically connected to the electric vehicle. Based on this, it can be determined whether or not the electric vehicle and the supply cable 33 are electrically connected. Alternatively, the connection detection unit 11 can also determine whether the electric vehicle and the supply cable 33 are electrically connected based on whether communication with the electric vehicle is possible.

  On the other hand, if voltage can be detected from the charger or battery of the electric vehicle regardless of whether control signal communication is possible with the charger of the electric vehicle, etc., power supply to the electric vehicle Whether or not the electric vehicle and the supply cable 33 are electrically connected may be determined based on whether or not the voltage can be detected from the line related to the above.

  When the connection detection unit 11 determines that the supply cable 33 is connected to the electric vehicle, the connection detection unit 11 outputs a connection confirmation signal to the control unit 10. When the connection confirmation signal is input, the control unit 10 starts the operation of storing the EV pallet 3E on which the electric vehicle is mounted in the EV parking shelf 4E.

  On the other hand, if the connection detection unit 11 determines that the supply cable 33 is not connected to the electric vehicle, the connection detection signal is not output to the control unit 10. In this case, the control unit 10 outputs a control signal that issues a warning that the supply cable 33 is not connected to the electric vehicle from at least one of the voice guidance unit 15V, the alarm buzzer unit 15B, and the display lamp unit 15L.

For example, when a warning is issued from the voice guidance unit 15V, a warning message “No charging cable is connected” is sent from the voice guidance unit 15V.
When a warning is issued from the alarm buzzer unit 15B, a buzzer sound is emitted from the alarm buzzer unit 15B. At this time, warning contents such as the charging cable not being connected may be displayed as a message on the display unit of the operation panel of the mechanical parking lot 1 or the like.
When a warning is issued from the display lamp unit 15L, the warning lamp in the display lamp unit 15L is turned on, and a warning content such as “Caution for charging cable” is displayed as a message on the display unit of the operation panel of the mechanical parking lot 1 or the like. Is displayed.

  Thereafter, when the connection detection unit 11 determines that the supply cable 33 is connected to the electric vehicle and a connection confirmation signal is input from the connection detection unit 11 to the control unit 10, the control unit 10 sets the EV on which the electric vehicle is mounted. The operation of storing the pallet 3E in the EV parking shelf 4E is started.

  In this embodiment, the operation of closing the entrance door is performed first, and then applied to the case where the above-described warning is issued. However, the present invention is not limited to this, and the above-described operation is performed first. The operation of closing the entrance door may be performed after issuing a warning, and is not particularly limited.

  First, the control unit 10 selects an EV parking shelf 4E that stores an EV pallet 3E on which an electric vehicle is mounted, from among the empty EV parking shelves 4E. Next, the controller 10 raises the lift 6 and moves the EV pallet 3E on which the electric vehicle is mounted to a position adjacent to the selected EV parking shelf 4E.

Then, the control unit 10 slides the EV pallet 3E on which the electric vehicle is mounted, and stores the EV pallet 3E on which the electric vehicle is mounted on the selected EV parking shelf 4E.
Thereby, storing of the EV pallet 3E in the EV parking shelf 4E is completed (step S10-1).

At this time, the trolley overhead wire 34 of the EV pallet 3E and the current collecting arm 42 of the EV parking shelf 4E are electrically connected.
That is, when the EV pallet 3E slides toward the EV parking shelf 4E, the trolley overhead line 34 of the EV pallet 3E approaches the current collecting arm 42 as shown in FIG. 2, and as shown in FIG. A current collecting arm 42 is disposed below the trolley overhead line 34.

  Specifically, when the trolley overhead wire 34 approaches the current collecting arm 42, the guide portion 35 of the trolley overhead wire 34 and the current collecting 43 of the current collecting arm 42 come into contact with each other. At this time, the plate-like current collector 43 biased upward enters the inside of the guide groove 37 of the guide portion 35 and is guided to the conductive groove 38 of the energization portion 36.

  The current collector 43 led to the conductive groove 38 is urged upward by the spring 49 of the current collecting arm 42, that is, toward the bottom surface of the conductive groove 38, so that the trolley overhead wire 34 and the current collecting arm 42 are electrically connected. Connected.

Thereafter, the control unit 10 starts charging the electric vehicle that has been stored in the EV parking shelf 4E (step S11-1).
Specifically, the control unit 10 outputs a control signal to the power supply unit 14 so as to supply power to the EV parking shelf 4E in which the electric vehicle is stored.

  Based on the input control signal, the power supply unit 14 starts supplying power to the current collecting arm 42 of the EV parking shelf 4E in which the electric vehicle is stored. The supplied electric power is supplied to the stored electric vehicle via the current collecting arm 42, the trolley overhead line 34, and the supply cable 33. The supplied power is charged into the battery via the charger of the electric vehicle.

  For example, when the charger of the electric vehicle detects whether or not the battery is fully charged and outputs a signal to that effect when the battery is fully charged, the fully charged signal is input to the control unit 10. The When the fully charged signal is input, the control unit 10 outputs a control signal for stopping the supply of power to the power supply unit 14. The power supply unit 14 stops the supply of power based on the input control signal.

Thereafter, when an instruction to leave the electric vehicle is input from the user to the control unit 10, the control unit 10 starts an operation of releasing the electric vehicle.
First, the control unit 10 raises or lowers the lift 6 to a position adjacent to the EV parking shelf 4E in which the electric vehicle to be delivered is stored.

Then, the control unit 10 slides the EV pallet 3E on which the electric vehicle is mounted from the EV parking shelf 4E toward the carrier of the lift 6, and moves the lift 6 on which the electric vehicle and the EV pallet 3E are mounted. Lower to boarding part 5.
When the EV pallet 3E on which the electric vehicle is mounted arrives at the entry portion 5, the turning portion 51 rotates the electric vehicle and the EV pallet 3E by about 180 °, and the front portion of the electric vehicle is directed to the entrance door side.

Thereafter, the control unit 10 opens the entrance door of the boarding unit 5 and outputs a signal notifying the timer unit 12 that the entrance door has been opened. The timer unit 12 starts measuring the time that has elapsed since the entrance door opened based on the input signal.
The user enters the entry section 5 through the opened entrance door, removes the supply cable 33 from the electric vehicle, and gets into the electric vehicle.

  The connection detection unit 11 detects that the supply cable 33 has been removed from the electric vehicle, and stops outputting the connection confirmation signal to the control unit 10. The control unit 10 determines that the supply cable 33 has been removed from the electric vehicle based on the input of the connection confirmation signal being stopped.

  Thereafter, even when a signal notifying that a predetermined period has elapsed from the timer unit 12, the control unit 10 does not perform control to issue a warning. Alternatively, when it is determined that the supply cable 33 has been removed from the electric vehicle, a control signal for stopping the measurement of the time elapsed after the entrance door is opened is output to the timer unit 12.

Then, when the user gets into the electric vehicle and moves the electric vehicle forward for delivery, the electric vehicle crosses the optical axis of the photoelectric sensor in the position detection unit 53, and the position detection unit 53 detects the movement of the electric vehicle. . The detection signal output from the position detection unit 53 is input to the control unit 10.
In this case, the control unit 10 has already determined that the supply cable 33 has been removed from the electric vehicle. Therefore, the control unit 10 does not perform a control for issuing a warning based on the detection signal input from the position detection unit 53.

On the other hand, if the user advances the electric vehicle to leave the electric vehicle while the supply cable 33 is connected to the electric vehicle, a detection signal informing the position detection unit 53 that the electric vehicle has moved is sent to the control unit 10. Is input.
In this case, the connection confirmation signal that informs that the supply cable 33 is connected from the electric vehicle is continuously input to the control unit 10 from the connection detection unit 11. Therefore, the control unit 10 determines that the electric vehicle has moved while the supply cable 33 is connected, and outputs a control signal that issues a warning that the supply cable 33 has not been removed.

  Further, when the supply cable 33 is connected to the electric vehicle and the electric vehicle is stopped, a signal indicating that the predetermined time has elapsed is input from the timer unit 12 to the control unit 10. . Also in this case, the control unit 10 outputs a control signal that issues a warning that the supply cable 33 has not been removed.

  For example, a warning message that prompts the user to remove the supply cable 33, such as “Please remove it securely”, is sent from the voice guidance unit 15V. Nevertheless, if the supply cable 33 has not been removed from the electric vehicle, a warning message will be sent out to instruct to confirm removal of the supply cable 33, such as “Please confirm that it has been removed”. It is.

When a warning is issued from the alarm buzzer unit 15B, a buzzer sound is emitted from the alarm buzzer unit 15B. At this time, warning contents such as prompting to remove the supply cable may be displayed as a message on the display unit of the operation panel of the mechanical parking lot 1.
When a warning is issued from the display lamp unit 15L, the warning lamp in the display lamp unit 15L is turned on, and a warning content such as “Caution for charging cable” is displayed as a message on the display unit of the operation panel of the mechanical parking lot 1 or the like. Is displayed.

  By receiving these warnings, the user notices that the supply cable 33 is still connected to the electric vehicle and can remove the supply cable 33.

In addition, the control unit 10 manages at least one of the number of times the electric vehicle is charged and the time for each password that is identification information.
In this way, charging can be performed based on the number of times of charging and the charging time, and there is no need to provide a measuring device for measuring the charged power.

On the other hand, as shown in FIG. 8, when the control unit 10 determines that the vehicle to be stored is a conventional vehicle based on the input personal identification number, it is the conventional pallet 3 </ b> C, A vehicle or a conventional vehicle is not selected (step S3-2).
Then, the selected conventional pallet 3C is taken out from the EV parking shelf 4E or the conventional parking shelf 4C stored so far (step S4-2).

  The lift 6 descends to the loading section 5 with the selected conventional pallet 3 </ b> C placed thereon, and the conventional pallet 3 </ b> C arrives at the loading section 5. Then, the entrance door of the boarding part 5 is opened (step S5-2).

  A user who uses the mechanical parking lot drives a conventional vehicle to enter, enters the boarding portion 5 while moving forward, and places the vehicle on the conventional pallet 3C. When the user moves the conventional vehicle to the stop position on the conventional pallet 3C, the user parks the conventional vehicle on the conventional pallet 3C and gets off the conventional vehicle (step S6-2).

  Thereafter, as shown in FIG. 10, the user goes out of the entrance section 5 and presses a “door close” button to close the entrance door of the entrance section 5 to close the entrance door to the control section 10. An instruction to start the storage operation is input (step S8-2).

  When the “door closed” button is pressed, the control unit 10 closes the entrance door of the boarding unit 5 and starts a series of operations related to storing the conventional vehicle (step S9-2).

  First, the control unit 10 selects a conventional parking shelf 4C for storing the conventional pallet 3C on which the conventional vehicle is placed, from among the empty conventional parking shelves 4C. Next, the control unit 10 raises the lift 6 and moves the conventional pallet 3C carrying the conventional vehicle to a position adjacent to the selected conventional parking rack 4C.

Then, the controller 10 slides the conventional pallet 3C on which the conventional vehicle is placed, and stores the conventional pallet 3C on which the conventional vehicle is placed on the selected conventional parking shelf 4C.
Thereby, storing of the conventional pallet 3C in the conventional parking shelf 4C is completed (step S10-2).

Next, the power supply method in the maintenance work of the mechanical parking lot 1 will be described.
When performing maintenance work of the mechanical parking lot 1, as shown in FIG. 1, the worker changes the mode of control by the control unit 10 from the sales mode for entering and leaving the electric vehicle and the conventional vehicle to the maintenance work mode. Switch.

  Then, the worker selects the EV parking shelf 4E in which the EV pallet 3E for performing maintenance work is stored, or the EV parking shelf 4E in which the EV pallet 3E close to the place where the maintenance work is performed is stored, The selected EV parking shelf 4E is input to the control unit 10. Then, the control unit 10 supplies power to the selected EV parking shelf 4E with respect to the power supply unit 14 regardless of whether an electric vehicle or a conventional vehicle is stored in the selected EV parking shelf 4E. Supply.

  The worker can obtain electric power from the supply cable 33 of the EV pallet 3E stored in the selected EV parking shelf 4E, and can perform maintenance work on the mechanical parking lot 1.

  According to the above configuration, the EV pallet 3E on which the electric vehicle is mounted is stored in the EV parking shelf 4E, and after the trolley overhead wire 34 and the current collecting arm 42 are in electrical contact, the electric power supply unit 14 supplies the electric pallet 3E. Supply of electric power to the automobile is started. Therefore, when the trolley overhead wire 34 and the current collecting arm 42 are in electrical contact with each other, it is possible to prevent a spark from being generated, and it is possible to prevent the connection end from being deteriorated by the spark.

  Furthermore, in order to supply electric power after the trolley overhead wire 34 and the current collecting arm 42 are electrically connected, the current collecting arm 42 exposed to the outside before the EV pallet 3E is stored in the EV parking shelf 4E is used. On the other hand, no power is supplied. Therefore, a short circuit or electric shock in the current collecting arm 42 can be prevented.

  When the EV pallet 3E is stored in the EV parking shelf 4E, the current collecting 43 of the current collecting arm 42 is pressed against the current conducting portion 36 by the link portion 44, so that the current is passed between the trolley overhead wire 34 and the current collecting arm 42. Is possible. On the other hand, by removing the EV pallet 3E from the EV parking rack 4E, the trolley overhead wire 34 and the current collecting arm 42 can be separated.

  Even if the deflection of the pallet body 31 of the EV pallet 3E is deformed downward due to the weight of the electric vehicle, the deflection is absorbed by the link portion 44, and the contact between the energization portion 36 and the current collector 43 is easily maintained. be able to. Therefore, it is possible to easily ensure energization between the trolley overhead wire 34 and the current collecting arm 42.

Since the energizing unit 36 extends in the moving direction of the EV pallet 3E, even if the storage position of the EV pallet 3E stored in the EV parking shelf 4E moves within a predetermined range, the energizing unit 36 and the current collector Since contact with 43 can be easily maintained, energization between the trolley overhead wire 34 and the current collecting arm 42 can be easily ensured.
In other words, it is not necessary to accurately fix the storage position of the EV pallet 3E with respect to the EV parking shelf 4E in order to ensure energization between the trolley overhead wire 34 and the current collecting arm 42.

  When the electric vehicle is placed on the EV pallet 3E and the warehousing process to be stored in the EV parking shelf 4E is started, if the supply cable 33 is not electrically connected to the electric vehicle, the control unit 10 An alarm is issued to the effect that the supply cable 33 is not connected. Therefore, the electric vehicle and the EV pallet 3E are not stored in the EV parking shelf 4E while the supply cable 33 is not electrically connected to the electric vehicle, and the electric vehicle is stored in the EV parking shelf 4E. When stored, the electric vehicle can be reliably charged.

  Furthermore, since the supply cable 33 was not connected to the electric vehicle at the time of warehousing, it is possible to prevent the situation where the electric vehicle cannot be used due to insufficient charging when the electric vehicle is delivered.

Furthermore, when starting the warehousing process, in other words, before the electric vehicle is stored in the EV parking shelf 4E from the entry unit 5, the control unit 10 indicates that the supply cable 33 is not connected to the electric vehicle. In order to issue an alarm to inform, the supply cable 33 can be easily connected to the electric vehicle.
For example, after storing the electric vehicle and the EV pallet 3E in the EV parking shelf 4E, in the method of issuing the above-mentioned alarm, the manager of the mechanical parking lot 1, the driver of the electric vehicle who is a user, etc. The electric vehicle stored in the EV parking shelf 4E cannot be easily approached, and the presence or absence of connection between the supply cable 33 and the electric vehicle cannot be visually confirmed. Furthermore, the supply cable 33 cannot be connected to the electric vehicle.

Further, after the electric vehicle is stored in the EV parking shelf 4E, the driver of the electric vehicle or the like has often left the mechanical parking lot 1 in many cases. Then, even if the electric vehicle is returned to the entry section 5 or the like, the driver of the electric vehicle or the like needs to connect the supply cable 33 to the vehicle, and the supply cable 33 may not be connected.
Furthermore, since the said vehicle exists in the boarding part 5, another user cannot park an electric vehicle or a conventional vehicle in the mechanical parking lot 1. FIG.

  When the stop position of the electric vehicle mounted on the EV pallet 3E moves and the supply cable 33 is connected to the electric vehicle, the control unit 10 keeps the supply cable 33 connected to the electric vehicle. A warning to that effect is issued. Alternatively, when a predetermined time has elapsed since the electric vehicle can go down from the EV pallet 3E, and the supply cable 33 is connected to the electric vehicle, the controller 10 supplies the supply cable. An alarm is issued to the effect that 33 remains connected to the electric vehicle.
