It has 104 and. Then, the parking device 100 of the present embodiment is a power supply device for supplying electric power to the electric vehicle housed in at least a part of the plurality of parking rooms 103 in order to charge the electric vehicle in the parking room 103. The 140 is provided with a power supply box 150 having a self-supporting shape and electrically connecting the power supply device 140 and the electric vehicle so as to be able to supply power to the electric vehicle. That is, the parking device 100 is characterized in that power is supplied to the electric vehicle via the power supply box 150 as the power supply repeater. The parking device 100 operates to park the vehicle in general, but operates to charge the electric vehicle at the time of parking only when the vehicle is an electric vehicle. Therefore, the term "vehicle" as used herein is a concept indicating a vehicle in general including an electric vehicle.

The boarding / alighting area 101 is arranged indoors of the parking device 100 so as to get on / off the vehicle. An external area adjacent to the lane is arranged outside the boarding / alighting area 101. The external area is an area communicating with the boarding / alighting area 101 via the doorway 106. The boarding / alighting area 101 is arranged at the same level as the lane so that vehicles can enter the lane or leave the lane. Further, the boarding / alighting area 101 and the external area are separated by an entrance / exit door 106. As shown in FIG. 2, an operation panel 107 is provided on the outer wall of the parking device 100 adjacent to the doorway 106. The user can open and close the doorway 106 and process the warehousing by temporarily stopping the vehicle in the external area for warehousing and inputting necessary information to the operation panel 107. Alternatively, the user can open and close the doorway 106, process the vehicle to leave the garage, and unload the vehicle from the boarding / alighting area 101 to the external area by inputting the information required for the operation panel 107 for warehousing. ..

The user advances the vehicle through the opened doorway 106 and enters the boarding / alighting area 101. The boarding / alighting area 101 is provided with a front wall portion 108 facing the front portion of the vehicle at a predetermined parking position. FIG. 6 shows a front view of the front wall portion 108 (viewed from the doorway 106 side). As shown in FIG. 6, a mirror 108a is arranged on the lower center side of the front wall portion 108. The user can park the vehicle in a predetermined position while checking the mirror 108a at the time of warehousing. Further, as shown in FIGS. 4 and 5, front and rear end detection sensors 117 and rear end detection sensors 118 for detecting front and rear protrusion of the vehicle from the vehicle accommodation space are provided before and after the vehicle accommodation space. ..

Further, as shown in FIG. 4, an optical sensor 109 is arranged in the boarding / alighting area 101. The configuration of the optical sensor 109 will be described with reference to FIGS. 5 to 8. Here, in the boarding / alighting area 101, the vehicle length direction of the parked vehicle is defined as the X direction, the vehicle width direction is defined as the Y direction, and the vehicle height direction is defined as the Z direction. Then, a vehicle accommodation space in which the electric vehicle is accommodated is set in advance on the boarding / alighting area 101 so that the electric vehicle can be safely stored in the parking room. If a part of the vehicle protrudes from the vehicle accommodation space (particularly the XZ plane), it may interfere with a part of the structure of the parking device 100 when the vehicle is transported, and a serious accident or failure may occur. That is, the vehicle accommodation space is sized so that the electric vehicle can be safely stored in the parking room.

The optical sensor 109 of the present embodiment is configured to detect protrusion of the charging palate or charging plug of the electric vehicle during charging from the XZ plane (which forms the boundary surface or the outer surface of the vehicle accommodation space). There is. Two optical sensors 109 are arranged on the left and right sides of the vehicle accommodation space in the vehicle width direction (Y direction). In the present embodiment, the optical sensor 109 is a general retroreflective photoelectric sensor composed of a light projecting unit 109a, a light receiving unit 109b, and a reflector 109c.

More specifically, the light projecting portion 109a of the optical sensor 109 is installed on the front side of the front wall portion 108 of the boarding / alighting area 101. In particular, it is fixed inward to the guide rails on both sides of the front wall portion 108. The light projecting unit 109a is configured to linearly radiate a laser beam such as infrared light from the front side to the rear side. As shown in FIG. 6A, the light projecting portion 109a is located at two positions on both sides of the mirror 108a of the front wall portion 109 in the Y direction at the first height (Z coordinate). In the present embodiment, as shown in FIG. 6B, the light projecting unit 109 includes three radiation units arranged at equal intervals in the Z direction. In other words, the light projecting unit 109a emits three light rays arranged at predetermined intervals in the Z direction. These three rays constitute the irradiation light (or the optical path L) from the light projecting unit 109a. Further, the light receiving unit 109b is arranged integrally or adjacent to the light emitting unit 109a. That is, the light emitting unit 109a and the light receiving unit 109b cooperate to form the light emitting and receiving unit. Although not shown, a transparent cover body that protects the light emitting unit 109a and the light receiving unit 109b may be provided.

The reflector 109c is formed on the inner surface of the doorway 106 on the rear side of the vehicle accommodation space so as to face the light emitting and receiving parts (light emitting part 109a and the light receiving part 109b) of the front wall portion 108. The reflector 109c is arranged at the same position in the Y direction with respect to the light emitting unit 109a and the light receiving unit 109b. Further, the reflector 109c is arranged to face the light emitting / receiving unit (light emitting unit 109a and the light receiving unit 109b) so as to be located at a second height (Z coordinate) higher than the first height in the Z direction. ing. That is, the reflector 109c is configured to inject the irradiation light emitted from the light projecting unit 109a and reflect it toward the light receiving unit 109b. Since the reflector 109c is formed on the inner surface of the doorway 106, it is arranged at a position corresponding to the light emitting / receiving unit only when the doorway 106 is closed. Since the width of the vehicle accommodation space in the Y direction is smaller than the width of the doorway 106, the reflector 109c is formed on the inner surface of the doorway 106 in order to simplify the structure.

The optical sensor 109 forms a predetermined optical path L that passes through a preset position of the charging port or charging port on the XZ plane of the vehicle accommodation space, and the light projecting unit 109a emits irradiation light along the optical path L. Radiate. That is, the optical path L is defined so as to extend the boundary surface of the vehicle accommodation space in the Y direction (vehicle width direction) along the XZ plane and pass through the XZ coordinates where the charging port or the charging port lid is located. Further, the optical path L has a predetermined width in the Z direction. Then, when an object exists in the optical path L, the irradiation light from the light projecting unit 109a is blocked, and the reflected light does not enter the light receiving unit 109b. The optical sensor 109 can detect the presence of an object on the optical path L by changing the signal of the light receiving unit 109b. As will be described later, when the optical sensor 109 detects the interruption of the optical path L, the control unit identifies the protrusion of the electric vehicle from the XZ plane of the vehicle accommodation space. In the present embodiment, as shown in FIG. 8, the light projecting unit 109a radiates the irradiation light so that the rear wheel side is higher than the front wheel side of the electric vehicle parked in the vehicle accommodation space. Generally, in many electric vehicles, the charging port on the rear wheel side is higher than the charging port on the front wheel side, so that the optical path L is configured to be inclined diagonally upward to the rear. .. As a result, even in an electric vehicle having a charging port on the front wheel side, the optical path L can pass through the position of the charging port or the charging palate on the XZ plane. The optical sensor can be movably controlled, and the control unit adjusts the angle of the optical path based on the vehicle model information received from the user, and the optical sensor (height of the optical path) passes through the position of the charging port for each vehicle model. May be controlled.

The elevating space 102 is a space for elevating and lowering the elevating lift 120, and extends over all layers. The height of the elevating space 102 is set by the desired number of parking rooms 103, that is, the number of floors of the parking tower. In the elevating space 102, the comb teeth of the elevating lift 120 and the comb teeth of the traversing tray 130 pass each other, so that the vehicle is transferred between the elevating lift 120 and the traversing tray 130.

Each parking room 103 is arranged so as to be paired on both sides of the elevating space 102 in the transverse direction on each floor different from the boarding / alighting area 101. Each parking room 103 is a space in which one vehicle can be parked and can be charged. In each parking room 103, a traversing tray 130 on which a vehicle is placed is arranged. As will be described later, the parking room 103 is provided with a power supply device 140 and / or a power supply terminal 141 capable of charging the electric vehicle when the vehicle is an electric vehicle. Reference numeral 140 in the figure is a power supply relay box, which constitutes a part of the power supply device.

The accommodating portion 104 is a space provided for accommodating the elevating lift 120 below the rotating floor 110 of the boarding / alighting area 101. That is, the accommodating portion 104 is a space recessed in the boarding / alighting area 101. In the operation of the parking device 100, the elevating lift 120 is accommodated in the accommodating portion 104 as a shelter position so as not to interfere with the rotation of the rotating floor 110. It can be detected by a sensor, a limit switch, or the like that the lift 120 is housed in the housing unit 104.

As shown in FIG. 3, the parking device 100 is stored in a rotating floor 110 installed in the boarding / alighting area 101, an elevating lift 120 for ascending / descending the elevating space 102, and a corresponding parking room 103 as a vehicle transport mechanism. In addition, a traversing tray 130 that traverses between the parking room 103 and the elevating space 102 substantially horizontally along the traversing rail is provided. The rotating floor 110 has a comb-shaped frame on which a vehicle can be placed, and is configured so that the direction of the vehicle can be changed to a predetermined angle. As an example, the rotating floor 110 has a comb tooth shape in which comb teeth extend outward from the central frame to the left and right. In this embodiment, the rotating floor 110 is set to rotate 180 degrees so that either the front or the rear of the vehicle faces the doorway 106. The elevating lift 120 has a comb-shaped frame on which a vehicle can be placed, and the frame is in the elevating direction with respect to the comb-shaped frame of the rotating floor 110 at both the unrotated position and the rotated position of the rotating floor 110. It is formed so that it can pass each other. As an example, the elevating lift 120 is composed of a pair of left and right frames, and comb teeth extend inward from the outer frame. In the present embodiment, as shown in FIG. 4, the elevating lift 120 is arranged at the same height as the rotating floor 110 of the boarding / alighting area 101 in the initial form, and only when the rotating floor 110 is rotationally driven, the rotating floor 110 It is evacuated to the accommodating portion 104 in order to avoid interference with. The traversing tray 130 has a comb-shaped frame on which an electric vehicle can be placed, and the frame is formed so as to be able to pass each other in the lifting direction with respect to the comb-shaped frame of the lifting lift 120. As an example, the traverse tray 130 has a comb tooth shape in which comb teeth extend outward from the central frame to the left and right. The traversing tray 130 is stored in each parking room 103. The traverse tray 130 is driven from the parking room 103 to the elevating space 102 along the traverse rail, and the position can be controlled more accurately by providing a limit switch (not shown) on the traverse rail. .. The transport mechanism is driven by a general drive mechanism such as a motor or a pulley based on a command from the control unit, but the description of the drive mechanism will be omitted here.

When the vehicle is stored in the predetermined parking room 103, the lift 120 retreats to the accommodating portion 104 as necessary for rotation while the vehicle gets into the boarding / alighting area 101 and the vehicle is placed on the rotating floor 110. (Or, the elevating lift 120 may be arranged in the accommodating portion 104 in advance), and the rotating floor 110 rotates. Then, when the elevating lift 120 rises, the comb-shaped frames of the rotating floor 110 and the elevating lift 120 pass each other, and the vehicle is transferred from the rotating floor 110 to the elevating lift 120. The lift 120 in the loaded state on which the vehicle is mounted is pulled up above the floor surface of the predetermined parking room 103, and the traverse tray 130 traverses in the lift space 102 and is arranged below the lift 120. Then, the elevating lift 120 descends, and the comb-shaped frames of the elevating lift 120 and the traversing tray 130 pass each other, so that the vehicle is transferred from the elevating lift 120 to the traversing tray 130. After the transfer, the traversing tray 130 on which the vehicle is mounted traverses the parking room 103 along the traversing rail, so that the vehicle is accommodated in the parking room 103.

It rises from 104. Then, the elevating lift 120 rises and stops above the traversing tray 130 so that the comb-shaped frames of the elevating lift 120 and the traversing tray 130 pass each other, and the vehicle is transferred from the traversing tray 130 to the elevating lift 120. Next, the empty traversing tray 130 traverses and is housed in the original parking room 103. Subsequently, the lift 120 in the loaded state descends to the ground floor, the vehicle is arranged in the boarding / alighting area 101, the comb-shaped frames of the lift 120 and the rotating floor 110 overlap each other, and the vehicle moves from the lift 120. It is placed on the rotating floor 110. If necessary, the rotating floor 110 rotates so that the vehicle can be delivered. When the rotating floor 110 needs to be rotated, the elevating lift 120 descends to the accommodating portion 104 and is transferred to the rotating floor 110, and then the rotating floor 110 rotates.

Further, the traverse tray side support piece 132 is provided with a power supply unit 136 that can be electrically connected to the connection terminal 155 formed on the bottom surface of the power supply box 150. On the other hand, the traversing tray side receiving hole 133 is bored in the floor member on one end side in the traversing direction. The distance from the traversing tray side receiving hole 133 to the tip of the traversing tray side support piece 132 is shorter than the distance between the pins 156 and 156.

Further, the traversing tray 130 is provided with a power receiving terminal 134 that electrically contacts the power feeding terminal 141 when the traversing tray 130 is stored in the corresponding parking room 103. The power receiving terminal 134 is formed at two positions in the front and rear of the side edge portion on the side end side, and corresponds to the position of the power feeding terminal 141. The power receiving terminal 134 is preferably arranged close to the traversing tray side holding body 131. Further, the power receiving terminal 134 is electrically connected to the power feeding unit 136 inside the traversing tray 130. That is, the traverse tray side holder 131 is configured to electrically connect the power receiving terminal 134 to the connection terminal 155 of the power supply box 150 when the power supply box 150 is held on the traverse tray side support piece 132. .. As a result, when the traverse tray 130 is stored in the parking room 103, the power supply terminal 141 can supply electric power to the power supply box 150 via the power reception terminal 134 and the power supply unit 136.

FIG. 12 shows in more detail the relationship between the power receiving terminal 134 of the traverse tray 130 and the power feeding terminal 141 of the power feeding device 140. As shown in FIG. 12A, when the traverse tray 130 is stored in a predetermined position of the parking room 103, the power receiving terminal 134 is in contact with the power feeding terminal 141, and the two are electrically connected to each other. On the other hand, as shown in FIG. 12B, when the traversing tray 130 traverses from the parking room 103 to the elevating space 102, the power receiving terminal 134 is separated from the power feeding terminal 141, and the electrical connection between the two is cut off.

Subsequently, the power supply box 150 as the power supply repeater of the present embodiment will be described with reference to FIGS. 13 to 15. 13 (a) to 13 (c) are a front view, a rear view, and a bottom view of the power supply box 150. FIG. 14 is a front view showing the internal structure of the power supply box 150. 15 (a) and 15 (b) are a front view and a plan view showing the internal structure of the power supply box 150 in a state where the cable 152 is pulled out by a predetermined length.

As shown in FIGS. 13 and 14, the power supply box 150 is housed in a housing 151 having a self-supporting shape, at least partially inside the housing so that the tip of the housing 151 is pulled out of the housing to an arbitrary length. The cable 152, the charging connector 153 attached to the tip of the cable 152 and connected to the charging port of the electric vehicle, and the cable 152 electrically connected to the inside of the housing and exposed to the outside of the housing. A connection terminal 155 that can be electrically connected to the power supply terminal 141 of the power supply device 140 is provided. The power supply box 150 is configured to be portable in the trunk of the user's electric vehicle. In the parking system of the parking device 100, the power supply box 150 is not commonly used among users, and is preferably stored individually by each user. In this case, the cable 152 is a dedicated cable defined for each vehicle.

The housing 151 is composed of a rectangular box, and has a door 151a that can be opened and closed on the front surface, and a handle 151b for opening and closing the door 151a. The user can access the inside of the housing by grasping the handle 151b and opening the door 151a. The housing 151 extends longitudinally in a plan view (top and bottom surfaces) and has a length direction and a width direction. The length direction of the housing 151 matches the transverse direction at the time of installation. The bottom surface of the housing 151 has a size and shape that can be placed and supported on the support pieces 112, 122, and 132 so that it can stand on the rotating floor 110, the elevating lift 120, and the traverse tray 130. Further, a pair of pins 156 and 156 are projected on the bottom surface of the housing 151. The pair of pins 156 and 156 are arranged apart from each other in the length direction and are located on both ends in the length direction of the bottom surface. Each pin 156 has a tapered tip and is pointed. The pin 156 has a shape that can be inserted into the receiving holes 113, 123, and 133. That is, the power supply box 150 has its bottom surface arranged on the support pieces 112, 122, 132 with one pin 156 inserted through the receiving holes 113, 123, 133, so that the holding bodies 111, 121, 131, respectively. Is held in. Further, the bottom surface of the housing 151 is provided with a pair of projecting pieces 157,157 that project from the bottom surface between a pair of pins 156 and 156 in the length direction and are arranged in the width direction of the bottom surface. The pair of projecting pieces 157, 157 are configured so as to be able to come into contact with the side end faces of the support pieces 112, 122, 132 while the power supply box 150 is held by the holding bodies 111, 121, 131. That is, the pair of projecting pieces 157 and 157 function to regulate the rotation of the power supply box 150 in the width direction about the pin 156. Further, a connection terminal 155 exposed to the outside is provided between the pair of pins 156 on the bottom surface of the housing 151.

The cable 152 is held by being wound inside the housing. The cable 152 is pulled out to the outside through an insertion hole formed on a side surface near the upper wall of the housing 151. This insertion hole has a size that allows the passage of the cable 152 but not the passage of the charging connector 153. A charging connector 153 is formed at the tip of the cable 152, and a plug 154a is formed at the base end. The plug 154a is connected to the outlet 154b inside the housing 151. The outlet 154b is wired so as to be electrically connected to the connection terminal 155 inside the housing. The cable 152 may generally be prepared by the user depending on the type of electric vehicle.

Further, the power supply box 150 further includes a regulating member 158 for regulating the pullable length of the cable 152 according to the distance between the selected holding bodies 111, 121, 131 and the charging port of the electric vehicle. The regulating member 158 is fixed to the cable 152 at a position separated from the charging connector 153 by a predetermined distance. The regulating member 158 has a size that does not allow it to pass through the insertion hole, and is locked to the inner surface of the housing 151 when the cable 152 is pulled out. As shown in FIGS. 15A and 15B, the user presets the position of the regulating member 158 according to the distance between the selected holding bodies 111, 121, 131 and the charging port of the electric vehicle. This makes it possible to pull out the cable 152 with a certain length. Since the positions of the holding bodies 111, 121, and 131 to be selected are determined by the positions of the charging ports of the electric vehicle, it becomes easy to connect the power supply box 150 and the charging port without slack. In other words, since the pull-out length of the cable 152 is regulated by the regulating member 158, it is possible to prevent the cable 152 from being pulled out more than necessary and to prevent the cable 152 from hanging down and coming into contact with other members. Is possible. When the cable 152 is pulled out to a predetermined length and the power supply box 150 is not used, the cable hook 151c provided on the upper part of the housing 151 does not have to be rewound. The cable 152 can be wound around.

Subsequently, the process of parking the electric vehicle V in the charged state will be described with reference to FIGS. 16 to 21. FIG. 16 is a flowchart showing a warehousing process of an electric vehicle.

First, the user (warehousing user) performs an authentication operation or the like on the operation panel 107. The control unit receives the user input information from the operation panel 107 together with the input instruction from the user (S101). The control unit collates the user input information from the user and opens the doorway 106 (S102). The user stops the electric vehicle V on the rotating floor 110 of the boarding / alighting area 101 through the open doorway 106. The control unit confirms that the user has stopped the electric vehicle V in the boarding / alighting area 101 (S103). This confirmation step is performed by a sensor (not shown) in the boarding / alighting area 101.

Next, when it is determined from the user input information that the electric vehicle V needs to be charged, the control unit requests the user to install the power supply box 150 on the rotating floor side holding body 111 (S104). This requirement also includes the connection of the charging connector 153 to the charging port V1. Further, this request is made by any means such as a screen display on the operation panel 107, a display of the boarding / alighting area 101, and a voice instruction.

Next, the user takes out the power supply box 150 from the trunk of the electric vehicle V, opens the charging port lid V2, and arranges the power supply box 150 in the rotating floor side holding body 111 located closest to the charging port V1 of the electric vehicle V. .. Then, the charging connector 153 extending from the power supply box 150 by a predetermined length is connected to the charging port V1. At this time, the opened charging port V2 protrudes most toward the vehicle width (Y) direction. The user only needs to place the power supply box 150 on the rotating floor side holding body 111, and does not need to search for an outlet on the parking device side for connecting the cable 152 in the boarding / alighting area 101 as in the conventional case. Then, the control unit confirms the completion of installation of the power supply box 150 by a signal from the limit switch 115 (see FIG. 20) described later (S105).

Subsequently, the user moves from the boarding / alighting area 101 to the outside via the doorway 106, operates the operation panel 107, and executes the warehousing process. Specifically, the control unit requests the user to confirm safety such as whether or not there are any people or objects left in the boarding / alighting area 101 (S106). After completing the safety confirmation visually or the like, the user inputs to the operation panel 107 that the safety confirmation has been completed, for example, by pressing the safety confirmation button. After receiving the safety confirmation information from the user, the control unit requests the user to input the operation start instruction (S107). After receiving the instruction to start the operation, the control unit closes the doorway 106 (S108). By closing the doorway 106, the reflector 109c is arranged to face the light emitting unit 109a and the light receiving unit 109b, and the optical path L of the optical sensor 109 is formed (see FIGS. 17 and 18).

Next, the control unit determines whether or not the electric vehicle V in the charging port V1 protrudes from the XZ plane of the vehicle accommodation space based on the presence or absence of the cutoff detection of the optical path L using the optical sensor 109 (S109). Proceed to.

As shown in FIG. 18, when the charging connector 153 connected to the charging port lid V2 and the charging port V1 is housed in the vehicle accommodation space inside the optical path L in the vehicle width (Y) direction, the optical sensor 109 is used. Since the irradiation light from the light projecting unit 109a is incident on the light receiving unit 109b via the reflector 109c, the blockage of the optical path L is not detected. The control unit receives the signal from the optical sensor 109, determines that the electric vehicle V does not protrude from the vehicle accommodation space, and proceeds to the next transfer step (S111).

On the other hand, as shown in FIG. 19, when the charging palate V2 protrudes from the vehicle accommodation space, the charging palate V2 hits the irradiation light from the light projecting unit 109a, and the light receiving unit 109b cannot receive the reflected light or receives the light. The strength decreases. The optical sensor 109 detects the interruption of the optical path L and transmits a signal to the control unit. Then, the control unit receives a signal from the optical sensor 109 that detects the interruption of the optical path L, and identifies the protrusion of the electric vehicle V from the XZ plane of the vehicle accommodation space. Then, the control unit cancels (cancels) the warehousing instruction and issues a warning to the user (S110). This warning may instruct the user to re-deliver the electric vehicle. Based on this warning, after the user restocks the electric vehicle, the control unit confirms that the electric vehicle is stopped (S103) and requests the user to install a power supply box on the rotating floor holder (S104). Followed. In FIG. 19, the protrusion of the charging palate V2 from the vehicle accommodation space is illustrated, but the protrusion of the charging connector 153 and the cable 152 can be detected in the same manner.

That is, immediately after the doorway 106 is closed and before the operation of the transport mechanism (lifting lift 120) is started, the protrusion of the electric vehicle is detected by the step (S109), the warehousing instruction is stopped, and the user is notified. Therefore, it is possible to reduce the time required for restocking, prevent the user from leaving, and prevent the vehicle from being left behind in the boarding / alighting area 101.

Subsequently, the transport process (S111) of the parking device 100 of the present embodiment will be described in detail. In the transport process (S111), both the electric vehicle V and the power supply box 150 are transported to the designated parking room (hereinafter, designated parking room) 103. The designated parking room 103 may be assigned in advance according to the user, may be input to the operation panel 107 by the user, or may be arbitrarily determined from the vacant parking room 103 by the control unit. Good.

FIG. 20 schematically shows a form in which the power supply box 150 is held by the rotating floor side holding body 111. As shown in FIG. 20, one pin 156 of the power supply box 150 is inserted into the rotating floor side receiving hole 113, and the bottom surface of the housing 151 is supported by the rotating floor side supporting piece 112. The other pin 156 is arranged in the empty space on the tip end side of the rotating floor side support piece 112. When one of the pins 156 comes into contact with the limit switch 115 formed in the rotating floor side receiving hole 113, the holding of the power supply box 150 by the rotating floor side holding body 111 is detected. Based on the signal from the limit switch 115, the control unit can determine which of the rotating floor-side holders 111 installed at the four locations holds the power supply box 150. In the present embodiment, as shown in FIG. 20, since the floor surface of the elevating lift 120 is arranged at the same height as the floor surface of the rotating floor 110, the power supply box 150 is the rotating floor side holding body 111. It is also held by the lifting lift side holding body 121. Specifically, the other pin 156 of the power supply box 150 is inserted into the elevating lift side receiving hole 123, and the bottom surface of the housing 151 is supported by the elevating lift side support piece 122. However, when the elevating lift 120 retracts to the accommodating portion 104, the power supply box 150 is held only by the rotating floor holder 111.

Further, two pairs of sensors 116, which are photoelectric sensors, are installed in the boarding / alighting area 101, and it is detected whether or not the power supply box 150 exists in the boarding / alighting area 101. The sensor 116 includes a light receiver and a floodlight, and the power supply box 150 is arranged on a virtual line between them to detect a change in the amount of light and detect the presence or absence of the power supply box 150. However, the form of the sensor is not limited to this embodiment, and the optical sensor may individually set each position of the rotating floor holder 111 as a detection range, or may set the entire boarding / alighting area 101 as a detection range. Further, as the optical sensor, a known infrared sensor or the like can be adopted. Alternatively, the optical sensor may be a camera that photographs the inside of the boarding / alighting area 101, and may be an image sensor that detects the presence / absence of the power supply box 150 by image processing the income image information.

Based on the holding position specified by the signal of the limit switch 115 and the position of the designated parking room 103, it is determined whether or not the rotating floor 110 needs to be rotated, and if necessary, the elevating lift 120 is retracted to the accommodating portion 104. The rotating floor 110 is rotated 180 degrees.

Next, the elevating lift 120 rises so as to pass the rotating floor 110, and the electric vehicle and the power supply box 150 are completely transferred from the rotating floor 110 to the elevating lift 120. As shown in FIG. 21, the power supply box 150 initially mounted on both the longitudinal piece-shaped rotating floor side support piece 112 and the U-shaped elevating lift side support piece 122 is provided with respect to the rotating floor side support piece 112. It is delivered to the lift-side support piece 122 that has risen relatively. As the elevating lift 120 rises, one pin 156 separates from the rotating floor side receiving hole 113 while the other pin 156 is inserted into the elevating lift side receiving hole 123. As a result, the power supply box 150 is supported only by the lift lift side support piece 122 whose bottom surface is U-shaped, and the other pin 156 is inserted into the lift lift side receiving hole 123, and the lift lift side holder 121 Retained only. At this time, a limit switch (not shown) may be similarly arranged in the lifting lift side receiving hole 123. The control unit can determine whether or not the power supply box 150 has been normally delivered by the signal from the limit switch. Then, the elevating lift 120 goes up to the floor where the designated parking room 103 is located.

Subsequently, after the elevating lift 120 stops at a predetermined height, the traversing tray 130 of the designated parking room 103 traverses the elevating space 102 and stops directly under the elevating lift 120. Next, the elevating lift 120 descends and passes by the traversing tray 130, so that the electric vehicle and the power supply box 150 are transferred from the elevating lift 120 to the traversing tray 130. The power supply box 150 mounted on the U-shaped lift lift side support piece 122 is delivered from the lift lift side support piece 122 lowered so as to pass the traverse tray side support piece 132 to the traverse tray side support piece 132. Is done. When the elevating lift 120 and the traverse tray 130 move relative to each other at the same height, the power supply box 150 is held by both the elevating lift side holding body 120 and the traversing tray side holding body 130. Then, as the lifting lift 120 is further lowered, one pin 156 is inserted into the traverse tray side receiving hole 133, and the other pin 156 is separated from the lifting lift side receiving hole 123. As a result, the power supply box 150 is supported only by the traversing tray side support piece 132 whose bottom surface is elongated, and one pin 156 is inserted into the traversing tray side receiving hole 133, and the traversing tray side holding body 131 Retained only. At this time, a limit switch (not shown) may be similarly arranged in the traverse tray side receiving hole 133. The control unit can determine whether or not the power supply box 150 has been normally delivered by the signal from the limit switch. Then, the traversing tray 130 traverses to the designated parking room 103 and is stored in the designated parking room 103.

The traversing tray 130 stored in the designated parking room 103 is in a state where power can be supplied from the power supply terminal 141 of the power supply device 140 (see FIG. 12), and the power supply box 150 is electrically connected to the power supply terminal 141 and held. .. That is, the electric vehicle is housed in the parking room 103 in a state where it can be charged from the power supply terminal 141 via the power supply box 150. Then, the control unit controls the power feeding device 140 and starts charging the electric vehicle.

In the warehousing process, the electric vehicle and the power supply box 150 are delivered from the traverse tray 130 to the elevating lift 120, and the electric vehicle and the power supply box 150 are received from the elevating lift 120 to the rotating floor 110 in a process opposite to the warehousing process. By handing over, the electric vehicle and the power supply box 150 can be transported to the boarding / alighting area 101 in a state where they can be delivered. In the boarding / alighting area, the user can remove the charging connector 153 from the charging port, lift the power supply box 150, and collect it from the rotating floor side holding body 111. Preferably, the power supply box 150 is collected in the trunk of the electric vehicle. However, if the power supply box 150 is shared, it may be returned to the manager of the parking device 100. Then, the user delivers the electric vehicle to the outside of the boarding / alighting area 101, and completes the shipping process while operating the operation panel 107.

The present invention is not limited to the above embodiment, and various embodiments and modifications can be taken. Hereinafter, another embodiment of the present invention will be described.

[Another Embodiment, Modification Example]
(1) The optical sensor of the present invention is not limited to the retroreflective sensor using a reflector, and may be another photoelectric sensor as long as it can form a linear optical path. For example, the optical sensor may be a transmissive photoelectric sensor in which the light receiving unit directly receives the irradiation light from the light projecting unit. In this case, the light emitting unit and the light receiving unit are arranged in front of and behind the electric vehicle with a vehicle accommodation space in between. Specifically, the light receiving unit is arranged at the position of the reflector of the above embodiment (that is, the inner surface of the doorway).

(2) The optical sensor of the present invention is not limited to the retroreflective sensor using a reflector, and may be another photoelectric sensor as long as it can form a linear optical path. For example, the optical sensor may be a distance setting type photoelectric sensor. The distance setting type photoelectric sensor is arranged in either one of the front and rear directions of the vehicle accommodation space, and has a light emitting / receiving unit in which a light emitting unit and a light receiving unit are integrated. In the distance setting type photoelectric sensor, the irradiation light from the light projecting unit is reflected by an object on the optical path, and the light receiving unit reads the reflected light to detect the blockage of the optical path. That is, the optical sensor does not require the installation of a reflector or a light receiving portion on the inner surface of the doorway on the opposite side of the light emitting portion. Due to the difference in the structure of the optical sensor, in addition to the control flow shown in FIG. 16, the warehousing process shown in FIG. 22 is possible as another form.

First, the user (warehousing user) performs an authentication operation or the like on the operation panel. The control unit receives the user input information from the operation panel together with the input instruction from the user (S201). The control unit collates the user input information from the user and opens the doorway (S202). The user parks the electric vehicle on the boarding / alighting area through the open doorway. The control unit confirms that the user has stopped the electric vehicle V in the boarding / alighting area. Next, when it is determined from the user input information that the electric vehicle needs to be charged, the control unit requests the user to install the power supply repeater in the holder (S204). The user then places the power supply repeater on the holder. Then, the charging connector of the power supply repeater is connected to the charging port. The control unit confirms the completion of installation of the power supply repeater (S205). Subsequently, the user moves from the boarding / alighting area to the outside through the doorway, operates the operation panel, and executes the warehousing process. Specifically, the control unit requests the user to confirm safety such as whether or not there are any people or objects left in the boarding / alighting area 101 (S206). After receiving the safety confirmation information from the user, the control unit determines whether or not the electric vehicle protrudes from the XZ plane of the vehicle accommodation space at the charging port based on whether or not the optical path is blocked by the optical sensor. Proceed to (S207). The step (S207) is executed with the doorway open.

When the charging connector connected to the charging port or the charging port fits in the vehicle accommodation space inside the optical path in the vehicle width (Y) direction, the optical sensor reflects the irradiation light from the light projecting portion on the shield. Since it is not detected, the blockage of the optical path is not detected. The control unit receives the signal from the optical sensor, determines that the electric vehicle does not protrude from the vehicle accommodation space, and proceeds to the step (S209) of requesting the next user to input an instruction to start driving. After receiving the instruction to start the operation, the control unit closes the doorway 106 (S210) and proceeds to the next transfer step (S211).

On the other hand, when the charging palate or the charging connector protrudes from the vehicle accommodation space, the charging palate hits the irradiation light from the light projecting unit, and the light receiving unit reads the reflected light. As a result, the optical sensor detects the blockage of the optical path and transmits a signal to the control unit. Then, the control unit receives a signal from the optical sensor that detects the interruption of the optical path, and identifies the protrusion of the electric vehicle V from the XZ plane of the vehicle accommodation space. Then, the control unit cancels (cancels) the warehousing instruction and issues a warning to the user (S208). This warning may instruct the user to re-deliver the electric vehicle. Based on this warning, after the user restocks the electric vehicle, the control unit confirms that the electric vehicle is stopped (S203) and requests the user to install a power supply repeater on the holding body (S204). Continue.

That is, in the flowchart of FIG. 22, since the protrusion of the electric vehicle is detected by the step (S207) before the door is closed, the protrusion of the electric vehicle is detected at an early stage, and the time required for restocking is increased. Can be effectively reduced. In addition, since the warehousing instruction is stopped and the user is notified before the door is closed, it is possible to prevent the user from leaving and to prevent the vehicle from being left in the boarding / alighting area. In this embodiment, since the step (S207) is executed before the door is closed and before the operation of the transport mechanism (elevating lift) is started, the step is compared with the first embodiment. However, in general, the distance setting type photoelectric sensor is more expensive than the retrospective reflection type photoelectric sensor and the transmission type photoelectric sensor, so that it is disadvantageous in terms of cost.

(3) In the above embodiment, the light projecting portion of the optical sensor is arranged on the front wall portion, but the light projecting portion may be installed on the inner surface of the doorway at the rear of the vehicle accommodation space.

(4) The optical sensor of the present invention has charging ports on the front and rear surfaces of the vehicle in place of or in addition to those forming an optical path on the XZ plane of the vehicle accommodation space as in the above embodiment. An optical path may be formed on a YZ plane so as to correspond to an electric vehicle. FIG. 23 is a schematic view showing the boarding / alighting area 201 of the parking device 200 of another embodiment. As shown in FIG. 23, the boarding / alighting area 201 is provided with an optical sensor 209 including a light emitting unit 209a, a light receiving unit 209b, and a reflector 209c installed in front of and behind the electric vehicle accommodated in the vehicle accommodation space. .. The optical sensor 209 expands the detection area in the Z direction of the existing front end detection sensor 217 and rear end detection sensor 218. The light projecting unit 209 is configured to radiate irradiation light along a predetermined optical path L passing through a preset charging port or charging palate position on the YZ plane of the vehicle accommodation space. The optical path L is set to pass a predetermined height (Z coordinate) corresponding to the charging port or charging port lid on the YZ plane of the vehicle accommodation space. As shown in FIGS. 24A and 24B, when the charging port V1 is on the front side of the electric vehicle V, the optical sensor 209 of the optical path L due to the protrusion of the charging port lid V2, the charging connector 253 or the cable 252. By detecting the interruption, the control unit can identify the protrusion of the electric vehicle V from the YZ plane of the vehicle accommodation space to the front. On the other hand, as shown in FIGS. 25A and 25B, when the charging port V1 is on the rear side of the electric vehicle V, the optical sensor 209 is the optical path L due to the protrusion of the charging port lid V2, the charging connector 253 or the cable 252. By detecting the interruption of the electric vehicle V, the control unit can identify the protrusion of the electric vehicle V from the YZ plane of the vehicle accommodation space to the rear.

(5) In the above embodiment, the power supply repeater does not have to be a power supply box, that is, a housing-shaped power supply repeater. For example, the power supply repeater may have a stand shape. Alternatively, the power supply repeater and the holder may be omitted from the parking device.

(6) The parking device of the above embodiment is a parking tower having a plurality of levels and two or more parking rooms are installed on the same level. The present invention provides, for example, a parking lot for home use. The same can be applied to a parking lot having a minimum configuration in which the rotating floor is omitted and there is only one parking room.

(7) In the parking device of the above embodiment, the elevating lift is retracted from the accommodating portion so that the rotating floor can rotate, but the present invention is not limited to this configuration. That is, in the parking device of the present invention, the accommodating portion may be omitted. In this case, the elevating lift is initially placed on the floor of the boarding / alighting area, the rotating floor is lifted above the elevating lift (instead of the elevating lift retracting to the accommodation), and the rotating floor rotates so as not to interfere with the elevating lift. It will be possible. In this modified example, it is possible to omit the provision of the accommodating portion, and the floor surface is located just below the comb teeth, so that it is suitable for wheelchair users.

(8) In the present invention, when the power supply box is held in the traverse tray side holding body and the traverse tray is stored in the corresponding parking room, the connection terminal of the power supply box electrically contacts the power supply terminal. It may be configured in. In this case, the connection terminal of the power supply box is electrically contacted with the power supply terminal of the parking room (including contact type and non-contact type) while being held by the traverse tray side holding body in the parking room without passing through the traverse tray. ), The arrangement relationship is designed. For example, as an example, the connection terminal is not arranged on the bottom surface of the power supply box but is exposed on the side surface of the housing facing the side end side of the parking room, and is parked while being held by the traverse tray side holder. It is placed facing the power supply terminal of the room.

The present invention is not limited to the above-described embodiments and modifications, and can be implemented in various embodiments as long as it belongs to the technical scope of the present invention. That is, within the technical scope of the present invention, some configurations of the present embodiment may be omitted or modified, or other configurations may be added.
