Patent Document 1

[0005] However, the invention described in Patent Document 1 includes a power supply terminal disposed outside the movement path of the pallet while corresponding to at least one specific parking space among the parking spaces, and a pallet provided with a relay terminal on the parking space side to which power is supplied from the power supply terminal. The pallet is moved using a pallet moving mechanism so that the relay terminal on the parking space side contacts the power supply terminal. Therefore, a large pallet on which a vehicle is mounted has to be moved to a position outside the movement path of the pallet, and each time, the pallet moving mechanism has to be accurately driven. Further, when moving the pallet in the parking space, the pallet moving mechanism has to be accurately driven to return the pallet to the movement path. In other words, the pallet has to be moved each time the parking device is operated from a position where power is supplied to the pallet to a position on the movement path where power is not supplied to the pallet, or the pallet cannot be moved on the movement path. Furthermore, since the power supply terminal is disposed outside the pallet in plan view, the space efficiency of the parking device is inevitably reduced.

[0006] The invention described in Patent Document 2 includes a power supply terminal provided in at least one parking space among the parking spaces, and a pallet provided with a power receiving terminal. After the pallet moves to a stop position within the parking space provided with the power supply terminal, the pallet is further moved to a charging position on the power supply terminal side so that the power receiving terminal contacts the power supply terminal. Therefore, a large pallet on which a vehicle is mounted must be moved to a position outside the moving paths in the first and second directions of the pallet, and each time, the second moving device must be accurately driven. Also, when moving the pallet to the stop position, the second moving device must be accurately driven to return the pallet to the stop position that serves as the moving path. In other words, each time the parking device is operated, the pallet must be moved from the position where power is supplied to the pallet to the stop position on the moving path where power is not supplied to the pallet, or the pallet cannot be moved in the first or second direction. Further, since the power supply terminal is arranged outside the pallet in a plan view, the space efficiency of the mechanical parking lot is inevitably reduced.

[0007] The present invention can supply power while keeping the tray stopped at the normal stop position and can supply power immediately after movement. Also, since the tray having the power receiving part can move from any direction with respect to the power supply part, no waste occurs in the operation of the mechanical parking device. Further, it aims to improve the space efficiency in the mechanical parking device.

In the drawings, the arrow W indicates the width direction of the device, the arrow D indicates the depth direction of the device, and the arrow H indicates the height direction of the device. Also, the width direction W of the device may be referred to as "the short side direction of the tray", the depth direction D of the device may be referred to as "the longitudinal direction of the tray", and viewing from the side in the height direction H of the device may be referred to as "plan view", respectively.

[0019] [Embodiment] <Overall Configuration of Mechanical Parking Device> As an embodiment of the present invention, the overall configuration of the mechanical parking device is shown in FIG. 1.

[0020] As shown in FIG. 1, the mechanical parking device 1 includes a tray 4 having a power receiving portion 60 on which a powered vehicle M is placed, a storage portion 2 in which the tray 4 is stored, and a plurality of storage compartments 3 provided in the storage portion 2 and having at least one empty compartment 3, the plurality of storage compartments 3 having a power supply portion 50 for supplying power to the power receiving portion 60.

[0021] [Storage Portion] Specifically, in the storage portion 2, a plurality of storage compartments 3 are set in a plurality of rows in both the device width direction W and the device depth direction D, and each storage compartment 3 is configured to be movable in the device width direction W or the device depth direction D. In this embodiment, only one layer is shown, but a plurality of storage portions 2 are provided along the device height direction H to form a multi-layer mechanical parking device 1. Further, in this embodiment, a plurality of empty compartments 3 are set to shorten the time required for the circulating movement of the tray 4.

[0022] Also, in a part of the storage portion 2, a lifting device 6 is arranged adjacent to a specific storage compartment 3, and the tray 4 circulated in the storage portion 2 is connected to a boarding and alighting room (not shown) installed above or below the storage portion 2 to lift the tray 4. Further, the lifting device 6 can also move the tray 4 between storage portions 2 of different layers in the multi-layer storage portion 2.

[0023] [Storage Compartment] The storage section 3 is composed of a vertical feed frame 32 and a horizontal feed frame 34, and each vertical feed frame 32 and horizontal feed frame 34 is configured to connect adjacent storage sections 3. In each storage section 3, there is installed a vertical and horizontal feed device (not shown) for moving the tray 4 in the direction of the device width W or the device depth D. Under the control of the control panel 10, it is appropriately moved in the direction of the device width W or the device depth D and moved within the storage section 2. Further, in each storage section 3, there is provided a power supply unit 50 of the power supply device 7 described later, and it is configured to be able to supply power to the tray 4 on which a vehicle equipped with a battery that requires power supply is placed. In this embodiment, as shown in FIG. 1, it is illustrated that all of the storage sections 3 and all of the trays 4 have a power supply unit 50 and a power receiving unit 60. However, when it is not necessary to provide the power supply device 7 having the power supply unit 50 in all of the storage sections 3, as an example, the power supply device 7 having the power supply unit 50 may be provided only in a plurality of storage sections 3 at a position far from the lifting device 6.

[0024] 〔Tray〕 As shown in FIGS. 1 and 2, in this embodiment, the tray 4 has a rectangular shape in plan view with the side along the device width W being short and the side along the device depth D being long, and has a thickness in the direction along the device height H. On the lower surface of the tray 4, a set of a vertical feed wheel 4A and a horizontal feed wheel 4B are provided in a total of 4 sets near the four corners of the tray 4. The vertical feed wheel 4A can travel on the vertical feed frame 32, and the horizontal feed wheel 4B can travel on the horizontal feed frame 34.

[0025] Further, as shown in FIGS. 2 and 7, on the tray 4, vehicle power supply devices 44 are provided at one or both ends in the depth direction D of the apparatus of the tray 4 so as to be tiltable about an axis 44 with respect to the tray 4. The vehicle power supply device 44 is provided with an electric outlet for power supply on the side of the free end that faces upward when erected. As shown in FIG. 7, the vehicle power supply device 44 is tilted so as to be stored in a storage portion 44B provided on the tray 4. When the vehicle power supply device 44 is stored in the storage portion 44B, the vehicle power supply device 44 is used as a part of the road surface so that the vehicle can run. Further, the tray 4 has a flat upper surface, and a water stop member 42 is provided around the upper surface of the tray 4 to prevent moisture such as rainwater, snowmelt due to snow and ice brought in by the vehicle from flowing down to the surroundings. The moisture accumulating on the tray 4 is made to flow down to a drain gutter (not shown) by moisture guiding means (not shown) provided at the notch portions at both ends in the longitudinal direction of the tray 4. This notch portion may be provided at a position shifted in the short side direction of the tray with respect to the vehicle power supply device 44. Further, the water stop member 42 also has a function of preventing the in-vehicle charging cord 48 used when supplying power to the vehicle M equipped with a battery from falling outside the tray 4.

[0026] (Power receiving part) As shown in FIG. 2, the power receiving part 60 is installed on the lower surface of the tray 4, and a power receiving terminal 62 is provided facing downward in the device height direction H. In the present embodiment, three long members are provided at predetermined intervals in the depth direction D of the apparatus along the width direction W of the device as the power receiving terminals 62 (see also FIG. 1). The power receiving part 60 is configured such that a power supply part 50, which will be described later, comes into contact from below the tray 4 in the device height direction H to supply power.

[0027] <Configuration of the main part> Next, the configuration of the main part of the present invention will be described with reference to FIGS. 3 and 4.

[0028] [Power supply device] As shown in FIG. 3, the power supply device 7 has a drive part 70 that moves up and down in the vertical direction along the device height direction H facing the power receiving part 60, and includes a power supply part 50 that comes into contact with or separates from the power receiving part 60.

[0029] Specifically, the power supply device 7 includes a power supply unit 50 and a linear motor 70 that serves as a drive unit for raising and lowering the power supply unit 50. More specifically, the power supply unit 50 is provided with a power supply terminal 52 facing upward in the device height direction H, and the power supply unit 50 is provided at the upper end of a lifting member 54 that is supported so as to be able to move up and down by a lifting unit 72 integrally incorporated in the linear motor 70. In the present embodiment, three members that are long along the device width direction W are provided at a predetermined interval in the device depth direction D for the power supply terminal 52 (see also FIG. 1). Further, the linear motor 70 is attached to a bracket (not shown) provided on the vertical feed frame 32 by a fixing member 74. The linear motor 70 is provided with a position detection device 76 for detecting the position of the lifting member 54. By the position detection device 76 detecting the position of the lifting member 54, it is detected at which position the power supply terminal 52 of the power supply unit 50 is located. The configuration of the position detection device 76 will be described later.

[0030] 〔Position Detection Device〕 As shown in FIG. 4, the position detection device 76 includes a first detection sensor 76A for detecting the upward stop position of the lifting member 54 and a second detection sensor 76B for detecting the downward stop position of the lifting member 54. As an example, in the present embodiment, the first detection sensor 76A and the second detection sensor 76B are configured by limit switches. On the other hand, a member to be position-detected 56 is provided on the surface of the lifting member 54 facing the first detection sensor 76A and the second detection sensor 76B. When the upper end of the member to be position-detected 56 is detected by the first detection sensor 76A, it is configured to detect that the power supply terminal 52 of the power supply unit 50 has come into contact with the power reception terminal 62 of the power reception unit 60 provided on the tray 4. The lower end of the member to be position-detected 56 is at a position where it detects that the power supply terminal 52 of the power supply unit 50 and the power reception terminal 62 of the power reception unit 60 provided on the tray 4 have separated when the second detection sensor 76B detects. In the present embodiment, as an example, the member to be position-detected 56 is configured by a protruding striker that protrudes from the lifting member 54. Note that the portions where the first detection sensor 76A, the second detection sensor 76B, and the member to be position-detected 56 are provided are covered with a sensor cover 78.

[0031] <Function of the main part> Next, the function of the main part will be described with reference to FIGS. 3 to 6.

[0032] As shown in FIG. 3, the power supply unit 50 is located at a position away from the power receiving unit 60. Here, when the linear motor 70 raises the lifting member 54 in the direction of arrow C shown in FIG. 6 in response to a start signal from the control panel 10, the first detection sensor 76A detects the upper end of the detected position member 56 and contracts in the direction of arrow B, and a detection signal is transmitted from the first detection sensor 76A to the control panel 10, and the linear motor 70 stops under the control of the control panel 10. At this time, as shown in FIG. 5, the power supply terminal 52 of the power supply unit 50 contacts the power receiving terminal 62 of the power receiving unit 60. Since this contact state is confirmed by the detection signal from the first detection sensor 76A, the control panel 10 transmits a signal instructing the power supply unit 12 shown in FIG. 1 to supply power, and the power supply unit 12 supplies power to the power receiving unit 60 that is the new power supply destination. At this time, if there is a power receiving unit 60 (tray 4) that has already been supplied with power, the power supply is configured to continue to be supplied.

[0033] On the other hand, there are cases where power supply is not required or power supply is temporarily interrupted. First, when the battery mounted on the vehicle is fully charged and a signal is issued, the control panel 10 stops the power supply to the storage compartment corresponding to the power supply unit 12, and in addition, gives a start signal to the linear motor 70 to lower the lifting member 54 in the direction of arrow A shown in FIG. 4. When the second detection sensor 76B detects the detected position member 56 and contracts in the direction of arrow B, a detection signal indicating the lowered position is transmitted to the control panel 10 to stop the linear motor 70.

[0034] Second, in the mechanical parking device 1, when the control panel 10 receives an instruction for storage or retrieval from an operation panel provided outside the passenger compartment (not shown), the control panel 10 temporarily stops all power supply to the storage compartments 3 having the power supply devices 7 in the storage unit 2. To do so, the control panel 10 transmits a signal to the power supply unit 12 to stop the power supply to all the power supply devices 7, and a signal to lower the lifting member 54 with respect to the linear motor 70 so that the power supply unit 50 moves away from the power receiving unit 60, thereby shifting to the state shown in FIG. 3. Then, when the storage or retrieval operation in the mechanical parking device 1 is completed and the movement of the tray 4 in the storage unit 2 is completed, the power supply device 7 can contact the power supply unit 50 with the power receiving unit 60 again to resume the power supply.

[0035] In this way, the power supply device 7 can contact or separate the power supply unit 50 and the power receiving unit 60 according to the state at that time. Further, since the power supply device 7 is disposed on the lower surface side of the tray 4, the power supply unit 50 does not protrude outside the outer periphery of the tray 4. Even when the storage unit 2 has a plurality of layers, the power supply device 7 is within the height range of the longitudinal and lateral feed devices that move the tray 4, so that the space efficiency is improved. Furthermore, although there are restrictions on the orientation in plan view of the power supply terminal 52 of the power supply unit 50 and the power receiving terminal 62 of the power receiving unit 60, the power supply unit 50 is configured to rise and contact the power receiving unit 60 from below in the device height direction H. Therefore, there is no restriction on the moving direction of the tray 4 with respect to the power supply unit 50.

[0036] Thus, the mechanical parking device of the present invention The position is for placing a vehicle to be powered a tray 4, and said tray 4 is provided at a predetermined one place on the lower surface of a power receiving unit 60, a storage unit 2 in which the tray 4 is stored, and a power supply device 7 having at least one empty compartment in the storage unit 2 and having a power supply unit 50 for supplying power to the power receiving unit 60 is provided a plurality of storage compartments 3, and a mechanical parking device 1 configured to include in which The power supply device 7 is provided at one place facing the power receiving part 60 in any one of the storage compartments 3 of the storage compartment 3, to the power receiving unit 60 whereas is provided with a power supply unit 50 that has a linear motor 70 for moving up and down in the vertical direction to contact or separate from the power receiving unit 60 the power supply part 50 has a configuration in which, when power supply is not required or power supply is temporarily interrupted, it moves away from the power receiving part 60, and when power supply is resumed, the power supply part 50 comes into contact with the power receiving part 60 to resume power supply, and the tray 4 is movable in any direction in the horizontal and vertical directions in plan view when the power supply part 50 is separated from the power receiving part 60 .

[0037] Accordingly, compared with moving the tray 4 from the normal stop position to the power supply position, power supply can be performed while the tray 4 is stopped at the normal stop position, and power supply can be immediately performed even after the movement. Further, since the tray 4 having the power receiving unit 60 can move from any direction with respect to the power supply unit 50, no waste occurs in the operation of the mechanical parking device 1. Furthermore, the space efficiency in the mechanical parking device 1 is improved.

[0038] Also, the power supply unit 50 is disposed below the tray 4.

[0039] Accordingly, compared with the case where the power supply unit 50 is disposed outside the outer peripheral portion of the tray 4, no waste of space occurs, and the space efficiency of the mechanical parking device is improved.

[0040] Also, when the power supply unit 50 does not require power supply or temporarily interrupts power supply, it separates from the power receiving unit 60, and when the power supply is resumed, the power supply unit 50 comes into contact with the power receiving unit 60 and the power supply is resumed.

[0041] Accordingly, compared with the case where the tray 4 is moved from the normal stop position to the power supply position for power supply, the control of power supply and stop is simplified.

[0042] Also, the tray 4 is movable in any direction with respect to the power supply unit 50.

[0043] Accordingly, compared with the case where there is a restriction on the moving direction due to the direction of the terminals of the power supply unit 50 and the power receiving unit 60, the tray 4 can be moved to the storage compartment for power supply from any direction.

[0044] As described above, the embodiments of the present invention have been described with reference to the respective embodiments. However, these embodiments are merely examples, and various modifications can be made without departing from the gist of the present invention. Needless to say, the scope of rights of the present invention is not limited to these embodiments.

[0045] For example, although the linear motor 70 has been described as the mechanism for raising and lowering the power supply unit 50 of the power supply device 7, the present invention is not limited thereto, and any configuration may be used as long as it can support the lifting member 54 for raising and lowering the power supply unit 50 in a liftable manner.

[0046] Also, although the power supply device 7 has been described as being provided on the longitudinal feed frame 32, the present invention is not limited thereto, and it may be provided on the lateral feed frame 34 or may be provided by rising from the floor surface of the storage unit 2.

[0047] In addition, although the mechanical parking device 1 has been described in a mode of arranging the storage compartments 3 in a plane, the present invention is not limited thereto, and it goes without saying that the present invention can also be applied to an elevator-type multi-story parking device, that is, a storage compartment adjacent to an elevator arranged in the vertical direction, and the type of the mechanical parking device is not limited.
