[0035] <Main components> next, In an embodiment Regarding the main components While referring to the drawing explain.

[0036] [fruit Embodiment] fruit The battery mounting tray according to the embodiment will be described with reference to FIGS.

[0037] 〔fruit Configuration of the embodiment] fruit 3 and 4, in the battery mounting tray according to the embodiment, a battery 70 is mounted inside 44C1 of a support 44C of a vehicle power supply device 44 that is foldably mounted on a flat upper surface 4C of the tray 4. One end of the battery 70 is electrically connected to a power receiving unit 60 provided below the tray 4 by a power supply-side wiring 74. The other end of the battery 70 is electrically connected to an outlet 46 provided above the vehicle power supply device 44 by a charging-side wiring 76.

[0038] A charging cable 48 for charging a storage battery (not shown) mounted on the vehicle M is connected to the outlet 46.

[0039] As shown in FIG. 4 , a storage section 44B is opened on the top surface 4C of the tray 4, and the vehicle power supply device 44 is stored in the storage section 44B when the vehicle power supply device 44 is laid down. While FIGS. 3 and 4 show the vehicle power supply device 44 in an upright state, as shown in FIG. 10 , the vehicle power supply device 44 is laid down and stored in the storage section 44B, which is provided in a direction intersecting the direction of travel of the vehicle M, around the axis 44A. In this state, the top surface of the vehicle power supply device 44 in the laid down state is at approximately the same height as the top surface 4C of the tray 4, and the top surface of the vehicle power supply device 44 forms part of the path along which the vehicle M travels. Furthermore, as shown in FIG. 10 , the vehicle power supply device 44 can be provided on the tray 4 at the front or rear of the vehicle M. This is intended to accommodate both vehicle models in which the charging connector 48C is connected to the front side of the vehicle M and vehicle models in which the charging connector 48C is connected to the rear side of the vehicle M, regardless of the position of the battery 70.

[0040] Details of vehicle power supply device 44 will be described with reference to Fig. 5. In Fig. 5, a portion of vehicle power supply device 44 is shown in cross section. As shown in Fig. 5, vehicle power supply device 44 has a built-in battery 70. In this embodiment, battery 70 is detachably fixed at its lower and upper ends by fixing members 72 inside interior 44C1 of support column 44C. When battery 70's performance deteriorates, it can be detached from fixing members 72 and replaced with a new battery 70.

[0041] In this embodiment, one end, or lower end, of the battery 70 is electrically connected to a power receiving unit 60 provided below the tray 4 by power supply-side wiring 74. The other end, or upper end, of the battery 70 is electrically connected to an outlet 46 provided above the vehicle power supply device 44 by charging-side wiring 76. A mounting base 45 and a charging cable receptacle 45A that support various parts of a charging cable 48, which will be described later, are provided on the support pillar 44C.

[0042] Power plug 48A, control box 48B, and charging connector 48C are each connected to charging cable 48, power plug 48A is connected to outlet 46, control box 48B is placed on and supported by mounting base 45, and the portion of charging cable 48 sandwiched between control box 48B and charging connector 48C is supported by charging cable receptacle 45A. Charging connector 48C is the portion that is connected to vehicle M.

[0043] 〔fruit Function of the embodiment fruit In the embodiment having the above-described configuration, battery 70 built into vehicle power supply device 44 receives power from power supply unit 50 via power receiving unit 60 and is charged via power supply side wiring 74. Charged battery 70 supplies power to power plug 48A of charging cable 48 via outlet 46 connected to charging side wiring 76. The power supplied to power plug 48A charges a storage battery (not shown) mounted on vehicle M via control box 48B and charging connector 48C. Tray 4 is circulated as it moves through each storage compartment 3 in storage unit 2 during loading and unloading operations, but battery 70 continues to charge the storage battery mounted on vehicle M without interruption, even while tray 4 is moving through each storage compartment 3 in storage unit 2.

[0044] In this way, Book Compared to a tray having only a power receiving unit, the battery mounting tray in the embodiment continues to supply power to the vehicle even while the tray 4 is moving. Also, because the battery 70 is built into the interior 44C1 of the support 44C of the vehicle power supply device 44, there is no need to ensure a space for the battery on the tray, compared to a tray in which the battery is located on the upper or lower side of the tray. Furthermore, because the vehicle power supply device 44 with the built-in battery 70 is stored in a lying position in the storage section 44B of the tray 4, the movement of the vehicle M on the tray 4 is smoother, compared to a tray in which the vehicle's entry is obstructed when the vehicle power supply device is lying down.

[0045] [ Reference example 1 ] next, Reference example 1 This will be described with reference to Figs. 6 and 7. is real Since the embodiments are similar, the same reference numerals will be used in the description.

[0046] [ Reference example 1 [Configuration of Reference example 1 In this case, the battery 70 is disposed on the upper surface 4C of the tray 4 in a position that does not interfere with the vehicle M on which it is placed. Specifically, as shown in FIGS. 6 and 7, the battery 70 is installed on the flat upper surface 4C of the tray 4. As shown in FIG. 7, the battery 70 is disposed on the edge of the tray 4 on the front left side of the vehicle M in a plan view of the tray 4. Both ends of the battery 70 are detachably fixed by fixing members 72. The battery 70 may be disposed on the tray 4 in any position that does not interfere with the movement of the vehicle M. For example, the battery 70 may be disposed on the rear left side of the vehicle M, or in any position that does not interfere with the driver's ability to get in and out of the vehicle M in a right-hand drive vehicle and the connection of the charging cable 48 between the vehicle M and the vehicle power supply device 44.

[0047] Both ends of battery 70 are detachably fixed to upper surface 4C of tray 4 by fixing members 72. Battery 70 is connected to power receiving unit 60 via power supply wiring 74, and is also connected to outlet 46 provided in vehicle power supply device 44 via charging wiring.

[0048] As shown in Fig. 10 , vehicle power supply device 44 is stored in a lying position in storage section 44B that is provided in a direction intersecting the direction of travel of vehicle M, with shaft 44A as the rotation center. In this state, the upper surface of vehicle power supply device 44 in the lying position is at approximately the same height as upper surface 4C of tray 4, and the upper surface of vehicle power supply device 44 forms part of the path along which vehicle M travels. Furthermore, as shown in Fig. 10 , vehicle power supply device 44 can be provided on tray 4 at the front or rear of vehicle M. This is intended to accommodate both vehicle types in which charging connector 48C is connected to the front side of vehicle M and vehicle types in which charging connector 48C is connected to the rear side of vehicle M, regardless of the position of battery 70.

[0049] [ Reference example 1 Action of Reference example 1 Battery 70 in ,fruit The only difference is that the battery 70 in the embodiment is not built into the vehicle power supply device 44. is real The same as the embodiment. Reference example 1 In this case, since the battery 70 is disposed on the upper surface 4C of the tray 4, maintenance and replacement of the battery 70 are easier than when the battery 70 is disposed on the lower surface 4D side of the tray 4.

[0050] [ Reference example 2 ] next, Reference example 2 This will be described with reference to Figs. 8 and 9. is real Since the embodiments are similar, the same reference numerals will be used in the description.

[0051] [ Reference example 2 [Configuration of Reference example 2 7 and 8, the battery 70 is disposed on the side of the lower surface 4D of the tray 4, above the lower surfaces of the wheels 4A and 4B that move the tray 4. Specifically, as shown in FIGS. 7 and 8, the battery 70 is detachably fixed via a fixing member 72 to a frame member 4F that supports the lower surface 4D of the tray 4. The lower surface of the battery 70 is disposed above the lower surfaces of the longitudinal feed wheels 4A and the lateral feed wheels 4B that are provided on the side of the lower surface of the tray 4.

[0052] 9, the battery 70 is disposed near the side of the vehicle M in a plan view of the flat tray 4, near the edge of the tray 4. The battery 70 is detachably fixed to the frame member 4F by a fixing member 72. The battery 70 may be disposed in any position below the tray 4 as long as it is near the edge of the tray 4. This is because a downward-facing drive rail (not shown) that contacts a drive device that moves the tray 4 is provided near the center of the tray's shorter side on the underside 4D side of the tray 4.

[0053] Battery 70 is detachably fixed near both ends thereof to frame members 4F that support underside 4D of tray 4 via fixing members 72. Battery 70 is connected to power receiving unit 60 via power supply wiring 74, and is also connected to outlet 46 provided in vehicle power supply device 44 via charging wiring 76.

[0054] As shown in Fig. 10 , vehicle power supply device 44 is stored in a lying position in storage section 44B that is provided in a direction intersecting the direction of travel of vehicle M, with shaft 44A as the rotation center. In this state, the upper surface of vehicle power supply device 44 in the lying position is at approximately the same height as upper surface 4C of tray 4, and the upper surface of vehicle power supply device 44 forms part of the path along which vehicle M travels. Furthermore, as shown in Fig. 10 , vehicle power supply device 44 can be provided on tray 4 at the front or rear of vehicle M. This is intended to accommodate both vehicle types in which charging connector 48C is connected to the front side of vehicle M and vehicle types in which charging connector 48C is connected to the rear side of vehicle M, regardless of the position of battery 70.

[0055] [ Reference example 2 Action of Reference example 2 Battery 70 in ,fruit The only difference is that the battery 70 in the embodiment is not built into the vehicle power supply device 44. is real The same as the embodiment. Reference example 2 In this case, the battery 70 is disposed on the lower surface 4D side of the tray 4, which prevents interference between the vehicle M traveling on the tray 4 and the battery 70 compared to when the battery 70 is disposed on the upper surface 4C side of the tray 4. In addition, the battery 70 is not affected by moisture brought in by the vehicle M.

[0056] [Variations] Next, a modified example will be described with reference to Figs. ,fruit embodiment Also, Reference Example 1 and Reference Example 2 The same components are designated by the same reference numerals, and different components are designated by new reference numerals.

[0057] Variations are ,fruit embodiment Also, Reference Example 1 and Reference Example 2The tray shape is different from that of the tray 104 in the modified example. The tray 104 in the modified example has an outer raised portion 104B at one end of the tray 104, and the battery 70 is disposed on at least one inner surface 104B1 of the raised portion 104B. Specifically, as shown in FIGS. 12 and 13, a car path portion 104A, which is the upper surface of the tray 104, is not flat, and the car path portion 104A is formed along the longitudinal direction of the tray 104, separated into left and right halves, which are the shorter side direction of the tray 104. The left and right separated car path portions 104A, 104A are fixed to a rib member 104F, and the tray 104 is formed as a whole. Here, the outer raised portion 104B is an example of a raised portion.

[0058] As shown in Fig. 13, the car road section 104A has raised portions on both sides of the tread surface 104D in the width direction W of the device, with an outer raised portion 104B on the side in the width direction W that is the outside of the tray 104, and an inner raised portion 104C on the side opposite the outer raised portion 104B that is the inside of the tray 104. A water receiving material 104E is provided on a frame member 104F between the left and right car road sections 104A, 104A. In this modified example, a keystone plate is used as the water receiving material 104E.

[0059] The battery 70 is detachably installed via a fixing member 72 so as to be housed in the inner surface 104B1 of the outer rising portion 104B of the roadway portion 104A. In this modification, as shown in Fig. 12, the battery 70 is arranged in the outer rising portion 104B on the right side of the vehicle M, but it may also be arranged in the outer rising portion 104B on the left side of the vehicle M, or on both sides.

[0060] In this modification, battery 70 is also connected to power receiving unit 60 via power supply wiring 74, and is also connected to outlet 46 provided in vehicle power supply device 44 via charging wiring 76. In this modification, vehicle power supply device 44 is fixed upright at the longitudinal end of outer rising portion 104B of tray 104. Note that in this modification, if vehicle power supply device 44 is to be able to rise and fall, it may be able to fall in a direction along the longitudinal direction of outer rising portion 104B.

[0061] [Effect of Modification] In this modified example, the different shape of tray 104 allows battery 70 to be placed so as to be stored on the inner surface 104B1 side of outer rising portion 104B, which contributes to improved space efficiency compared to tray 4 having a flat upper surface. Also, compared to a tray in which vehicle power supply device 44 stands upright in the path of the tray, it does not interfere with the movement of vehicle M on tray 104.

[0062] Thus, the battery-mounted tray of the present invention is a tray 4 having a power receiving section 60 on which the vehicle M to be powered is placed, and the tray 4 is equipped with a battery 70 for supplying power to the vehicle M and is electrically connected to the power receiving section 60.

[0063] As a result, power supply to the vehicle M continues even while the tray 4 is moving, as compared to a tray 4 having only the power receiving unit 60.

[0064] The tray 4 also has a flat upper surface 4C.

[0065] This allows for a larger space for the vehicle M to move around compared to a tray with a raised portion.

[0066] The tray 4 also has a vehicle power supply device 44 that is installed on the side of the upper surface 4C of the tray 4 so that it can be raised or lowered. The battery 70 is built into the vehicle power supply device 44.

[0067] This eliminates the need to ensure a space for placing the battery 70 on the tray 4, as compared to when the battery 70 is placed on the upper surface 4C side or the lower surface 4D side of the tray 4.

[0068] In addition, vehicle power supply device 44 is tilted in a direction intersecting the direction of movement of vehicle M on tray 4, and when vehicle power supply device 44 is tilted in storage section 44B of tray 4, it becomes part of the path of vehicle M.

[0069] This allows the vehicle M on the tray 4 to move more smoothly than if the vehicle power supply device 44 were to be laid down and still hinder the vehicle M from entering.

[0070] The battery 70 is disposed on the side of the upper surface 4C of the tray 4 at a position where it does not interfere with the vehicle M placed thereon.

[0071] This makes maintenance and replacement of the battery 70 easier than when the battery 70 is arranged on the side of the lower surface 4D of the tray 4.

[0072] The battery 70 is disposed on the side of the lower surface 4D of the tray 4, above the lower surfaces of the wheels 4A and 4B that allow the tray 4 to travel.

[0073] This avoids interference between the vehicle M traveling on the tray 4 and the battery 70, compared to when the battery 70 is placed on the upper surface 4C side of the tray 4. In addition, the battery 70 is not affected by moisture brought in by the vehicle M.

[0074] The tray 104 also has an outer raised portion 104B at one end of the tray 104, and the battery 70 is disposed on at least one inner surface 104B1 of the outer raised portion 104B.

[0075] As a result, compared to a tray 4 having a flat upper surface 4C, storing the battery 70 in the outer rising portion 104B of the tray 104 contributes to improving space efficiency.

[0076] The tray 104 also has a vehicle power supply device 44 that is installed upright on the upper surface side of the outer rising portion 104B of the tray 104.

[0077] This prevents vehicle power supply device 44 from interfering with the movement of vehicle M on tray 104, as compared to a case where vehicle power supply device 44 stands upright on vehicle path portion 104A of tray 104.

[0078] That's all, oneAlthough the present invention has been described with reference to the embodiments, these embodiments are merely examples, and various modifications can be made without departing from the spirit of the present invention. It goes without saying that the scope of the present invention is not limited to these embodiments.

[0079] For example, although the description has been given of a single battery 70 being installed on the tray 4, the present invention is not limited to this, and a plurality of batteries 70 may be mounted on the tray 4 separately.

[0080] Furthermore, although the battery 70 has been illustrated as a rectangular parallelepiped, this is not limited thereto, and the shape of the battery 70 may be any shape that does not interfere with the movement of the vehicle M on the tray 4 or tray 104 or the walking of the driver / user.

[0081] Furthermore, although the power supply unit 50 and the power receiving unit 60 are provided as a set for the tray 4 in the above example, the present invention is not limited to this, and a plurality of power supply units 50 and a plurality of power receiving units 60 may be provided for the tray 4 .

[0082] Furthermore, although the upper surface 4C of the tray 4 has been described as being flat, it is not limited to this and may have bends or curves such as a mountain or V shape to provide a water gradient, or may be press-formed or convex for the purpose of shear reinforcement.

[0083] Furthermore, the vehicle power supply device 44 may be manually lowered in a boarding / deboarding compartment (not shown), but a drive unit may be installed below the vehicle power supply device 44 to enable it to be lowered without manual operation. In this case, the vehicle power supply device 44 may be automatically raised when the tray 4 lands in the boarding / deboarding compartment by operating a control panel in the boarding / deboarding compartment to indicate that the vehicle requires charging.
