Description

  The present invention relates to a mechanical parking apparatus.

  As this type of mechanical parking device, there is a “mechanical parking device including a charging device” described in Patent Document 1.

  This mechanical parking device includes a power receiving side contact on a tray on which a vehicle is mounted and is movable. On the other hand, a charger connected to a power source and a power supply side contact connected to the charger are provided at a fixed side position, and the power supply side contact is disposed in a storage space of the vehicle. When the vehicle to be parked in the passenger compartment is received by the tray, if the vehicle is desired to be charged, the user connects the outlet of the storage battery of the vehicle and the power receiving side contact installed on the tray. Next, as in the case of a general mechanical parking apparatus, the tray is moved up and down mechanically and stored in a predetermined storage space. Each storage space has a charger connected to a power source and a power supply side contact, and when the tray carrying the vehicle is sent to a predetermined position in the storage space, the power receiving side contact of the tray and the position corresponding to this Automatically contact with the power supply side contact. In this way, the battery is charged by being charged from the power source through the charger, the power supply side contact, the power receiving side contact, and the outlet. Needless to say, the storage battery used in the present specification is not a storage battery provided in a general vehicle, but a storage battery provided as a power source for traveling (a power source for a traveling motor).

  In this mechanical parking apparatus, since the tray is always taken in and out of the storage space in one direction, the contact between the power receiving side contact and the power feeding side contact is also limited to one direction.

  In addition, an electric vehicle (EV) vehicle that needs to be charged (for convenience, hereinafter, an electric vehicle, a plug-in hybrid vehicle, etc. will be collectively referred to as an EV vehicle) and a tray for a general vehicle (for convenience, hereinafter, other than the EV vehicle). Since there is no concept of a compatible tray (a gasoline vehicle, a diesel vehicle, an LPG vehicle, etc. are generically referred to as a general vehicle), power supply side contacts and chargers are installed in all storage spaces.

Japanese Patent No. 2908940

  The present inventors considered the schemes a and b shown in FIG. 7 and FIG. 8 as the charging method for the EV car in the mechanical parking device.

  In the following, among various types of mechanical parking devices, it is applied to mechanical parking devices called pallet (or puzzle) types, which are known as mechanical parking facilities that can efficiently park a large number of vehicles in a small space. To explain. A pallet-type mechanical parking apparatus is usually configured to have a plurality of layers by including an elevating mechanism called a lifter. Further, the pallet is the same as the tray of Patent Document 1 in that the pallet is mounted and moved.

  In a pallet-type mechanical parking device, a vehicle is placed on the pallet in the passenger compartment, and the pallet is moved forward and backward, left and right using rails and grooves, so that an empty space (parking space or storage space) is obtained. ). In addition, if it is necessary when conveying a pallet to the vacant space, it will be the mechanism to move the pallet which loaded the vehicle already parked. Furthermore, parking efficiency is further improved by combining a lifter (elevating mechanism) for raising and lowering the pallet and a three-dimensional parking layer to form a multi-tier structure. The EV vehicle is assumed to have an outlet for connecting the mounted storage battery to an external power supply for charging.

(Draft a)
In FIG. 7, one or more predetermined parking spaces among a plurality of parking spaces are prepared as charging parking spaces equipped with a power supply facility capable of charging EV cars. A wiring facility using a cable 600 is installed on the pallet, and one end of the cable 600 can be connected to an outlet of an EV car by a plug, and the other end of the cable 600 is fixed to the pallet as a power receiving side contact. The user connects the plug of the cable 600 installed on the pallet 200 to the outlet of the EV car 300 placed on the pallet 200 in the passenger compartment 100. Subsequently, the pallet 200 is automatically conveyed to a predetermined charging parking space 400 and stopped at the charging position of the charging parking space 400. When the pallet 200 is stopped at the charging position, the power receiving side contact in the wiring facility of the pallet 200 and the power feeding side contact installed in the charging parking space 400 are automatically connected by an automatic detacher. After the connection is completed, charging of the storage battery of the EV car 300 is started.

  Since the pallet “a” cannot move the pallet at the charging position during charging, it may hinder the entry / exit of other vehicles.

(Draft b)
In FIG. 8, one or more predetermined parking spaces among a plurality of parking spaces are prepared as charging parking spaces equipped with a power supply facility capable of charging EV cars. The power supply facility includes a cable 700 having a plug. The pallet 200 on which the EV car 300 is placed in the passenger compartment 100 is automatically conveyed to a predetermined charging parking space 400 and stopped at the charging position of the charging parking space 400. Subsequently, the user connects the plug of the cable 700 installed in the charging parking space 400 to the outlet of the EV car 300.

  This plan b also cannot move the pallet at the charging position during charging. In addition, the user needs to leave the passenger compartment 100 and go to the charging parking space 400.

  As a result of comparative studies on the above methods, the present inventors have drawn the following conclusions.

  When considering the application of the present invention to a pallet-type mechanical parking device, it is desirable to enable charging to an EV car without impairing its free layout.

  From such a point of view, the present invention is intended to provide a mechanical parking device that hardly interferes with entering and leaving other vehicles in order to enable charging of an EV vehicle that is parked.

  The present invention relates to a mechanical parking device having a plurality of parking spaces and having a pallet driving device for moving the vehicle on a pallet and moving it on the pallet. Charging facilities are installed in parking spaces that are less likely to impair the smoothness of parking operations due to plane movement of pallets, or in a relatively small number of parking spaces relative to the total number of parking spaces. Thus, charging while parking without disturbing the smoothness of the parking operation of other vehicles is enabled.

  That is, a mechanical parking device according to the present invention includes a pallet on which a vehicle is mounted, a plurality of parking spaces for storing the pallets, and a pallet driving device that independently moves the pallets between the plurality of parking spaces. A charging facility for charging the storage battery mounted on the vehicle, and while the charging facility charges the storage battery mounted on the vehicle, the vehicle mounted on another pallet It is characterized by enabling entry / exit.

  The following aspects are mentioned as a preferable aspect of said mechanical parking apparatus.

  At least one parking space among a plurality of parking spaces is set as a charging parking space, and the charging facility charges the storage battery mounted on the vehicle in the charging parking space.

  At least one pallet is connectable to a storage battery mounted on the vehicle, and includes a wiring facility having a power receiving side contact, and the charging facility is a power feeding that can be connected to the power receiving side contact in the charging parking space. A side contact is provided, and charging electric power is supplied to the vehicle via the power feeding side contact and the power receiving side contact.

  At least two charging parking spaces are provided.

  The power receiving side contact is provided on at least one side surface of the plurality of side surfaces of the pallet.

  In the charging parking space, a position where the pallet should be stopped is set as a charging position, and when the pallet stops at the charging position, the power receiving side contact and the power feeding side contact are connected. The

  When a new vehicle requiring charging is received during charging of the storage battery in the charging parking space, the pallet carrying the vehicle requiring charging is temporarily moved to an empty parking space. When the charging of the storage battery in the charging parking space is completed, the pallet of the charging parking space is moved to another vacant parking space, and the pallet moved temporarily to the vacant parking space is The battery is moved to the charging parking space, and the storage battery of the vehicle placed on the pallet can be charged.

  The mechanical parking device according to the present invention has an effect that the storage of a vehicle represented by an EV vehicle can be charged, so that it is less likely to cause trouble in entering and leaving other vehicles.

It is sectional drawing which showed the state which the receiving side contact contacted the electric power feeding side contact of FIG. It is the figure which looked at the electric power feeding side contact shown in FIG. 11 from the left side of FIG.

  A pallet-type mechanical parking apparatus will be described as the first embodiment of the present invention, but it goes without saying that this is not the case. In addition, there are a normal charging facility and a quick charging facility as a charging facility for an EV car. In the following, a case of a pallet-type mechanical parking apparatus having a normal charging facility will be described first. As is well known, normal charging is a charging operation in which the charging time is several hours or more, and rapid charging is a charging operation performed in a sufficiently short time compared to normal charging. In addition, as described above, the EV car is usually provided with an outlet for connecting the mounted storage battery to an external power source.

  FIG. 1 is a plan view of a pallet-type mechanical parking device for one level (for two floors below), and FIG. 2 is a vertical sectional view of a right side portion of the mechanical parking device of FIG.

  This mechanical parking device is an example capable of storing less than 50 vehicles defined by 2 levels × (26 spaces−empty space), but it goes without saying that the present invention is not limited to this example.

  1 and 2, in the first embodiment, a space for lifting the pallet 20 by the lifter 50 is secured in the parking area on each floor at a location close to the center, connecting the passenger compartment 10 and the basement. . Of the parking spaces prepared on the first basement floor and the second basement floor, a corner of the parking area and a total of two parking spaces adjacent thereto are used as charging parking spaces. On the other hand, among the plurality of pallets prepared for the entire mechanical parking apparatus, in the first embodiment, at least four or more pallets are charging pallets that can correspond to the charging parking space. A charging pallet that can be used for a charging parking space is a cable that has a plug that can be connected to the outlet of an EV car at one end and a fixed receiving-side contact at the other end. It is a provided pallet.

  In FIG. 1 and FIG. 2, for convenience, the parking spaces for charging on the second basement floor are indicated by 40-1 and 40-2, and the pallets at the respective charging positions are indicated by 20-1 and 20-2. The charging position means a pallet stop position necessary for normal charging of the EV vehicle. Further, EV cars on the pallets 20-1 and 20-2 are indicated by 30-1 and 30-2. However, a parking space called a charging parking space and a pallet called a charging pallet are not parking spaces and pallets dedicated to EV vehicles, respectively. When EV vehicles are not charged, parking spaces and pallets for ordinary vehicles are used. Needless to say, it may be used as Moreover, even if it is an EV car, when there is no charging use, it may be stopped and used on a pallet for general vehicles. From the above, regardless of whether the vehicle is an ordinary vehicle or an EV vehicle, a pallet on which the vehicle is mounted and moved in a plane, its drive unit, and a control device that controls traveling can be collectively referred to as a pallet drive device. The above also applies to the second embodiment described later.

  In the following, a case where the EV car 30-1 on the pallet 20-1 as a charging pallet is charged in the charging parking space 40-1 on the second basement will be described, but the same applies to other charging parking spaces. It is.

  Referring to FIG. 3, pallet 20-1 is stopped at the charging position of charging parking space 40-1. On the rear side of the charging parking space 40-1, a power supply device 70 for supplying charging power is installed as a charging facility at a position slightly away from the pallet 20-1. An EV car 30-1 is mounted on the pallet 20-1, and a plug on one end side of a cable 21-1 provided on the pallet 20-1 is connected to an outlet 30-11 of the EV car 30-1. The other end of the cable 21-1, that is, the fixed power receiving side contact, is electrically connected to the power feeding side contact of the automatic detacher 60-1 installed at the rear portion of the charging parking space 40-1. The power supply side contact of the automatic detacher 60-1 is connected to the power supply device 70.

  Referring to FIG. 4, automatic detacher 60-1 moves backward (in the solid line in FIG. 4) and protrudes (the position in the dashed line in FIG. 4) in and out of case 62-1 by linear motion mechanism 61-1. It has a power supply side contact 63-1. Here, normal charging is taken as an example, and three contacts are shown as power supply side contacts, but two are used for power supply and one is used for grounding. Of course, these power supply side contacts are electrically insulated from each other. The insulation structure of the three power supply side contacts and the electrical connection structure with the power supply device 70 can be realized by using a well-known technique and are not the gist of the present invention, so detailed illustration and description thereof will be omitted.

  In the case of rapid charging, a plurality of terminals for charging control signals may be prepared.

  The power receiving side contact connected to the power supply side contact 63-1 is fixedly installed on the pallet, and the direction from which the automatic desorber 60-1 is approached upon connection is arbitrary. In FIG. 1, the pallet 20-1 currently located at the corner of the parking area enters the charging parking space 40-1 from the left side in FIG. 1 and the upper side in FIG. 1. This is because there is a case where the car enters (in this case, there is no pallet in the charging parking space 40-2).

  For this reason, in the first embodiment, the power receiving side contact is provided on the side surface on the rear side of the pallet, that is, the side surface corresponding to the rear side of the EV car, but may be the side surface on the front side of the pallet. You may provide in the side part corresponding to the side part side, ie, the side of an EV vehicle.

  In any case, the connection between the power receiving side contact and the power feeding side contact may be realized in any configuration, and another example will be described later.

  Next, the operation of the first embodiment will be described.

  When charging is required, it is input from the operation panel inside or outside the passenger compartment 10 that the target vehicle is an EV vehicle requiring charging, and the charging pallet is called into the passenger compartment 10. After placing the EV car on the pallet (charging pallet) transported to the passenger compartment 10 in FIG. 2, between the outlet (30-11 in FIG. 3) and the pallet (20-1 in FIG. 3). Connect with a cable (21-1 in FIG. 3). Subsequently, under the control of a control device (not shown) that receives an input from the operation panel, the pallet on which the EV car is placed is moved to the charging parking space 40-1 by moving up and down and moving in a plane. When stopping at the charging position of the charging parking space 40-1, the power receiving side contact of the pallet 20-1 and the power supply of the charging parking space 40-1 are performed by the automatic detacher 60-1 described with reference to FIGS. The side contact 63-1 is automatically connected. As will be described later, the automatic detacher 60-1 is combined with means for notifying the control device that the charging pallet has entered the charging parking space 40-1 and that the power receiving side contact and the power feeding side contact have come into contact. Has been. Upon receiving this notification, the control device starts charging the storage battery of EV vehicle 30-1 from power supply device 70.

  The control device monitors the charging state by monitoring the charging voltage, the charging time, and the like, and stops the power supply from the power supply device 70 when it is determined that the charging is completed. After that, when there is a pallet on which an EV car waiting for charging is placed, or when it is informed by an input from the operation panel that an EV car for which charging is newly desired has entered the passenger compartment 10, Control is performed in which an EV vehicle that has been charged is placed and the pallet 20-1 existing in the charging parking space 40-1 is moved to another parking space. As a result, a pallet carrying a new EV vehicle from the passenger compartment 10 is received in the charging parking space 40-1 that has become empty, and charging of the storage battery of the EV vehicle is started with the same operation as described above.

  By the way, as a countermeasure against the above-mentioned problem of the proposal (a), “the pallet at the charging position cannot be moved during charging”, a mechanical parking device serving as a moving path of the pallet for loading and unloading at the time of loading and unloading A parking space for charging is set at a position avoiding the route between the lifters, specifically at the corner of the parking area per level or close to it to minimize the impact on smoothness when entering and leaving. ing.

  In addition, when there is an EV vehicle that is being charged in the charging parking space due to the control operation of the control device, the EV that is being charged to the movement path of the pallet on which the other vehicle is placed when the other vehicle enters or exits. A movement route is determined so as not to include a charging parking space where a vehicle exists.

  In addition, for some reason, it is unavoidable for other pallets to pass and it is unavoidable to temporarily suspend and evacuate the EV vehicle being charged.

  In the example of FIG. 1 and FIG. 2, the parking space for 2 layers × 2 charging = 4 EV cars can be charged simultaneously, but the arrangement of the parking space for charging is arbitrary and can be increased or decreased. It is.

  Next, with reference to FIG. 5 and FIG. 6, a case of a pallet-type mechanical parking apparatus having a quick charging facility will be described as a second embodiment of the present invention. In the case of quick charging, charging may be completed in a short time of less than one hour, so that a plurality of EV cars can be assigned to one quick charging parking space. Thereby, the number of quick charging parking spaces, that is, the number of quick charging facilities can be reduced.

  The mechanical parking device of FIG. 5 is an example that can store less than 50 vehicles defined by 2 levels × (26 spaces−empty space), but is only an example. In addition, the quick charge parking space is only one of 40-1 ′ set in the corner on the second basement floor, and the number of quick chargers built in the power supply device 70 constituting the quick charge facility is one. However, this is merely an example, and two or more vehicles may be provided according to the total number of parking spaces.

  The mechanical parking device of FIGS. 5 and 6 is different from the mechanical parking device of FIG. 1 because of the number of parking spaces for charging and the number of quick charging facilities, wiring facilities using cables, and loading / unloading using a control device. Control operation. The automatic detacher 60-1 and the like for connecting the power receiving side contact and the power feeding side contact may be the same as those described with reference to FIGS.

  Next, the operation of the second embodiment will be described.

  When an EV car is placed on the pallet in the passenger compartment 10 of FIG. 6 and quick charging is required, the user inputs that fact through an operation panel installed in or outside the passenger compartment 10. . The user also connects the outlet of the EV car and the pallet with a cable. Subsequently, under the control of the control device that receives the input from the operation panel, the pallet carrying the EV vehicle is automatically transported toward the quick charging parking space 40-1 ′, and the quick charging parking space 40-1 When stopping at the charging position of ', the power receiving side contact installed in the quick charging parking space 40-1' and the power receiving side contact of the pallet 20-1 by the automatic detacher 60-1 described in FIG. 3 and FIG. Connect automatically. As in the first embodiment, the automatic detacher 60-1 informs the controller that the charging pallet has entered the quick charging parking space 40-1 ′ and that the power receiving side contact and the power feeding side contact have come into contact. The means for reporting is combined. Upon receiving this notification, the control device starts rapid charging of the storage battery of EV vehicle 30-1 from power supply device 70.

  The control device monitors the charging state by monitoring the charging voltage, the charging time, and the like, and stops power feeding from the power feeding device 70 when it is determined that the rapid charging is completed. After that, when the control device is informed by the input from the operation panel that an EV vehicle that desires a quick charge has entered the passenger compartment 10, the control device quickly puts on the EV vehicle that has already completed the quick charge. Control which moves the pallet 20-1 which exists in parking space 40-1 'for charge to another parking space is performed. As a result, a pallet equipped with a new EV vehicle from the passenger compartment 10 is received in the empty quick-charge parking space 40-1 ′, and the EV vehicle storage battery is rapidly charged in the same operation as described above. Start.

  When the control device is informed by the input from the operation panel that an EV car that has requested a new quick charge has entered the passenger compartment 10 during the above-described quick charging, the control device also removes the pallet on which the EV car is placed. Move to a vacant parking space. The same applies to the case where an EV vehicle that desires a quick charge continues, but the control device determines the position and the order in which the quick charge is to be performed for the pallet on which the EV vehicle that is to be subjected to the quick charge is placed. It is associated and remembered. Thus, when the quick charging for the EV car 30-1 in the quick charging parking space 40-1 ′ is completed, the control device moves the pallet 20-1 on which the EV car 30-1 is placed to another normal parking space. Move to. As a result, a pallet equipped with EV cars in the order in which rapid charging is to be executed next is received in the empty rapid charging parking space 40-1 ′, and the EV car storage battery is operated in the same manner as described above. Start charging quickly.

  According to the second embodiment as described above, in addition to the effects of the first embodiment, the number of charging facilities can be reduced by realizing the sharing of the quick charging facility.

(Effects of the first and second embodiments)
Charging EV cars by setting a parking space for charging (or a parking space for quick charging) at a position that avoids the path between the mechanical parking device and the lifter, which is the pallet movement path for loading and unloading. In particular, it is possible to store and retrieve other vehicles.

  Further, by providing an automatic detacher in the charging parking space (or the quick charging parking space), it is not necessary for the user to go to the parking space as in the above-mentioned plan b.

  By installing EV car charging pallets according to the number of EV cars that allow parking, it is not necessary to use all pallets as charging pallets, and an excessive increase in equipment costs can be avoided.

  In the above embodiment, the case of normal charging and the case of rapid charging have been described separately. For example, one of the charging parking spaces 40-1 and 40-2 in FIG. Needless to say, the parking space for quick charging may be a mechanical parking device having both functions of normal power reception and quick charging.

  Next, another example of the automatic detacher that connects the power receiving side contact and the power feeding side contact will be described with reference to FIGS.

  FIG. 10 shows the positional relationship between the power supply side contact and the power reception side contact necessary for enabling electric connection for charging the EV vehicle from a plurality of directions in the pallet type mechanical parking apparatus together with the moving direction of the pallet. It is the figure shown about the hierarchy part. Of course, this figure is only an example.

  In FIG. 10, the parking space is indicated by a rectangle, and the corner portion of the parking area is an area where the parking space cannot be installed due to a pillar of the building. A power supply side contact can be installed in a parking space indicated by a thin black rectangle among the parking spaces. In particular, the power supply side contact is installed on the wall side forming the mechanical parking device. On the other hand, the thick arrow shown in the parking space indicates the direction in which the pallet can move when the pallet is there. The pallet is controlled to (1) enter the target parking space while moving in a plane in its long axis direction and stop at the charging position, and (2) a direction perpendicular to the long axis direction (short axis) In some cases, the vehicle is controlled so as to enter the target parking space and stop at the charging position while moving in a plane. In the case of (1) above, it is sufficient to provide a power receiving side contact on at least one of the two side surfaces on the long axis side of the pallet, preferably both. In the case of (2) above, the two side surfaces on the short axis side of the pallet A power receiving side contact may be provided on at least one of these, preferably both. Of course, if power receiving side contacts are provided on the four side surfaces of the pallet, both of the above (1) and (2) can be handled. However, from the viewpoint of suppressing an increase in equipment cost, the pallet for (1) above, that is, a pallet having two power receiving side contacts on the two long side surfaces of the pallet, and the pallet for (2) above. That is, it is desirable to prepare two types of pallets each having a power receiving side contact on two side surfaces on the short axis side of the pallet.

  FIG. 11 is a cross-sectional view showing another example of the power supply side contact installed at the position indicated as the power supply side contact attachable position in FIG. 10, and FIG. 12 shows the power supply side contact shown in FIG. It is the cross section which showed the state which the provided power receiving side contact contacted.

  In FIG. 11, a support plate 120 is erected using a fixed frame 110 installed in a fixed state. A through hole is provided at a position near the upper portion of the support plate 120, and a probe 130 as a power supply side contact is movably inserted. A contact 131 is provided at the tip of the probe 130, and a power supply cable 133 is fixedly connected to the other end via a terminal, here a round crimp terminal 132. The cable 133 is connected to a power feeding device (for example, 70 in FIG. 3). A biasing coil spring 134 is provided between the contact 131 and the support plate 120, and the probe 130 is biased in a direction in which the contact 131 moves away from the support plate 120. Since the probe 130 is a power supply member, it is preferable that the probe 130 is electrically insulated except for the portion connecting the contact 131 and the round crimp terminal 132, and the support plate 120 is also preferably an insulating material. .

  In FIG. 12, as the pallet enters the charging parking space, the frame 300 constituting the pallet approaches the probe 130 from the right side in the drawing. A power receiving side contact 200 is attached to the lower side of the frame 300. The power receiving side contact 200 has a contact 201 at the tip, and the other end is covered with an insulating material 204 around a conductor 202 to which a cable 203 is connected. The other end of the cable 203 is provided with a plug that can be connected to an outlet of an EV car.

  When the power receiving side contact 200 approaches and the contact 201 contacts the contact 131, and the power receiving side contact 200 further approaches the support plate 120 side, the probe 130 moves backward against the biasing force of the coil spring 134, and the power receiving side contact 200 When 200 stops, the contact 131 continues to contact the contact 201 with the biasing force of the coil spring 134 applied. In this state, the storage battery of the EV vehicle is charged from the power feeding device via the cable 133, the probe 130, and the cable 203.

  13 is a view of the power feeding side contact shown in FIG. 11 as viewed from the left side of FIG. As described with reference to FIG. 4, a plurality of pairs of power supply side contacts and power reception side contacts are provided, here three pairs. Each pair has the same structure as described in FIGS.

  In order to prevent an unintended short circuit with another member, an electric shock, or the like, it is desirable that the periphery of the connection portion between the probe 130 and the cable 133 be covered with something like an insulating member. For example, as shown by a one-dot chain line in FIGS. 11 and 13, three connection portions can be collectively covered by providing a U-shaped insulating cover with the open side facing downward.

  The power receiving side contact 200 as shown in FIGS. 11 to 13 is provided on at least one of two side surfaces on the short axis side or at least one of two side surfaces on the long axis side in the pallet for charging. On the other hand, power supply side contacts having a plurality of probes 130 are provided at positions on the wall side of the parking space where the power supply side contact can be attached in the parking area described with reference to FIG.

  The probe 130 is not always energized, and it is desirable to start power feeding from the power feeding device after contact between the contact 131 and the contact 201. For this purpose, the charging pallet has entered the charging parking space and the power feeding side It is desirable to have a function of determining that the contact and the power receiving side contact are in contact. This can be realized in the following form.

1st form: Optical sensor The optical sensor 150 is provided in the fixing | fixed site | part of the fixed side flame | frame 110. FIG. On the other hand, on the frame 300 side of the charging pallet, for example, the insulating material 204, a reflector 250 is provided at a position where the light from the optical sensor 150 can be reflected when the contact 131 and the contact 201 are in contact. When the emitted light is reflected by the reflecting plate 250, the optical sensor 150 sends an ON signal to the control device. Upon receiving this ON signal, the control device determines that the charging pallet has entered and that the power supply side contact and the power reception side contact have come into contact, and enables power supply from the power supply device to the probe 130.

  The above function can also be realized by a projector and a light receiver.

Second Embodiment: Displacement Sensor Although not shown, a displacement sensor that detects the displacement of the probe 130 is provided in the vicinity of the probe 130. In the displacement sensor, the contact 201 is in contact with the contact 131 and the subsequent retraction of the entire probe 130 is detected and an ON signal is output. Upon receiving this ON signal, the control device determines that the charging pallet has entered and that the power supply side contact and the power reception side contact have come into contact, and enables power supply from the power supply device to the probe 130. The displacement sensor can also be realized by a limit switch that is turned on when the probe 130 is retracted to a predetermined position.

Third Mode: Proximity Sensor Although not shown, a proximity sensor is provided in place of the optical sensor of the first mode. On the other hand, on the frame 300 side of the charging pallet, for example, the insulating material 204, a detection site is provided at a position that can be recognized by the proximity sensor when the contact 131 and the contact 201 are in contact. When the proximity sensor detects the detection site, it sends an ON signal to the control device. Upon receiving this ON signal, the control device determines that the charging pallet has entered and that the power supply side contact and the power reception side contact have come into contact, and enables power supply from the power supply device to the probe 130. Proximity sensors are preferred because they are less susceptible to moisture and dirt.

  Since the control device knows in advance the transport destination of the charging pallet on which the EV vehicle is mounted, that is, the charging parking space, an ON signal from the optical sensor or the displacement sensor or the proximity sensor installed in the charging parking space. If it receives, it will be in the state which can supply electric power from the electric power feeder in the parking space for the charge.

  According to the installation form of the power receiving side contact to the pallet and the installation form of the power supply side contact to the charging parking space, the following effects can be expected.

  1) Even if the number of receiving side contacts on the pallet is 1, the direction of the receiving side contact to be installed for each pallet is changed, that is, the location of the receiving side contact is set to one of the two short axes of the pallet. Alternatively, by using either one of the two long axes, the number of chargeable parking spaces that can be fed can be increased.

  2) When a plurality of power receiving-side contacts are provided on the pallet, the number of charging parking spaces that can be supplied with power increases, and the degree of freedom of the parking space increases and the smoothness during parking improves.

  3) Since it is possible to supply power from the power supply device after it has been determined that the charging pallet has entered and the power supply side contact and the power reception side contact have come into contact, an unintended short circuit or electric shock at the power supply side contact is possible. Etc. can be prevented.

  As described above, the present invention has been described with respect to several preferred embodiments. However, storage batteries mounted on EV vehicles are beginning to be provided with a power supply that can be charged directly from a commercial power outlet without using a special device. The present invention can be applied as a charging facility even if only the outlet of such a commercial power source is used.

  In the embodiment, as the wiring equipment mounted on the pallet, the plug that can be connected to the outlet of the EV car on one end side and the cable that has the fixed power receiving side contact on the other end side has been described. However, it is not limited to this form. For example, a cable having a plug that can be connected to the power supply port of the EV car on one end side and a plug that can be connected to an outlet installed on the pallet on the other end side may be used. Any configuration may be used as long as it can be electrically connected to the power feeding device.

  Furthermore, the pallet-type mechanical parking device may be a mechanical parking device having a form as shown in FIG. 9 instead of the one to which the first and second embodiments are applied.

  In FIG. 9, the user connects the plug of the cable 600 in the wiring facility installed on the pallet 200 to the outlet of the EV car 300 placed on the pallet 200 in the passenger compartment 100, and the pallet 200 is moving, Regardless of whether the vehicle is stopped or not, the power supply facility installed at a predetermined place in the parking area can be supplied with power at all times, and charging is performed even during the automatic conveyance of the pallet 200. For this purpose, power supply means such as a power supply rail 500 is installed along the movement path of the pallet, and the power supply rail 500 is connected to the wiring facility of the pallet and to the power supply facility. According to this embodiment, since there is no restriction on the charging place, charging is possible wherever the pallet is.
