Description

[Technical field]

[0001] The present invention relates to a tray for electric vehicles in a mechanical parking system and to a method for manufacturing or modifying the same. [Background technology]

[0002] In recent years, electric vehicles have started to become popular among automobiles. There are various types of electric vehicles, including battery electric vehicles (BEVs) that run purely on a battery and a motor, and plug-in hybrid vehicles (PHEVs) that use both an internal combustion engine and a motor and whose batteries can be charged with electricity from an external charging facility, and thus require battery charging.

[0003] In addition to normal charging, some vehicle models allow for rapid charging of the batteries. In either case, however, charging a battery takes a long time, so there is a growing demand for mechanical parking devices that are equipped with facilities that allow charging while the vehicle is parked.

[0004] In consideration of these circumstances, Patent Document 1 describes a pallet that is used to mount vehicles in a parking device having a plurality of parking spaces and a power supply unit, is capable of mounting a vehicle powered by a charging cable, and is powered by the power supply unit at least when placed in a parking space, the pallet comprising a pallet main structure which is a plate structure having a substantially rectangular shape when viewed from above and is provided with a pair of left and right rising portions that rise along a pair of left and right long sides and a pair of left and right guide surfaces that are parallel to each other between the pair of left and right rising portions and guide the left and right rolling tires of the vehicle, a vehicle-side relay terminal that can be electrically connected to the charging cable, a support mechanism that supports the vehicle-side relay terminal, and a relay device that relays power supplied from the power supply unit to the vehicle-side relay terminal, the pallet main structure having an opening on a side of the rising portions facing the guide surfaces, and the support mechanism stores the vehicle-side relay terminal in the rising portion so that it can be electrically connected to and detached from the charging cable through the opening.

[0005] Patent document 2 also describes a mechanical parking device that has a tray that is positioned in the direction of entry of a parked vehicle, and a charging unit that is provided on the tray and has a charging plug connection unit, and that connects the charging connector of a charging cable mounted on the vehicle to the power supply terminal of the parked vehicle mounted on the tray, and moves to a storage space with the charging plug of the charging cable connected to the charging plug connection unit to charge the battery while parked, in which the mechanical parking device is characterized in that the charging unit has an opening on the top surface of the tray, and is equipped with a storage chamber in which a control box of the charging cable can be stored during charging, and a lid member that closes the opening of the storage chamber via a hinge so as to be able to open and close, and which is approximately flush with the top surface of the tray when closed.

[0006] [Patent Document 1] JP 2012-188894 A [Patent Document 2] JP 2019-203361 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the parking device pallet described in Patent Document 1, a large opening W is provided on the inner surface of the rising portion F of the pallet 100, a support frame 151 is fixed to the outer surface of the rising portion F, and a vehicle side relay terminal 130 is provided on the support frame 151 inside the rising portion F. In the case of a pallet 100 having such a structure, the manufacturing process of the pallet 100 increases the steps of opening the opening W in the rising portion F and providing the support frame 151, and therefore the manufacturing process of normal pallets for non-electric vehicles must be changed in order to complete the pallet main structure 110 of the pallet 100. This requires a change to the pallet manufacturing line, which leads to a large increase in costs.

[0008] Moreover, the mechanical parking device described in Patent Document 2 includes a storage chamber 31 having a large opening 35 on the upper surface of a tray 5, and a charging plug connection part 33 is fixed to a retractable protection bracket 34 and a first side (fixing part) 42 inside the storage chamber 31, and a cover member 32 that closes the opening 35 is attached via a hinge 36, allowing the parked vehicle A to pass through. In the tray 5 having such a structure, the manufacturing process of the tray 5 requires an additional step of opening the opening 35 on the upper surface of the tray 5, a step of fixing the storage chamber 31 to the opening 35, and a step of fixing the protection bracket 34 and the first side (fixing part) 42 rotatably and fixing the charging plug connection part 33 to the first side (fixing part) 42. Therefore, the manufacturing process of a normal tray for a non-electric vehicle must be changed in order to complete the tray 5. This requires a change to the tray manufacturing line, which leads to a large increase in costs.

[0009] The present invention aims to provide a tray for an electric vehicle that enables charging of an electric vehicle without requiring changes to the tray production line, since the basic structure of the tray is the same as that of a tray for a normal non-electric vehicle, thereby enabling the production of a tray for an electric vehicle with simple operations and at low cost. [Means for solving the problem]

[0014] An electric vehicle charging tray of a mechanical parking device of the fifth aspect is a vehicle guidance device of a mechanical parking device of the first or second aspect, wherein the opening is positioned so that a charging plug can be inserted from the side and connected.

[0015] A method for manufacturing or modifying an electric vehicle charging tray of a mechanical parking device according to a sixth aspect includes a tray of the mechanical parking device that is rectangular in plan view and has a charging device with a built-in charging plug connection portion on the upper surface of at least one corner of the tray, a current collecting member on the underside of the tray, and a wire passing hole through which wiring that supplies power to the charging plug connection portion can be passed in a frame member of the tray, the charging device has a charging plug connection portion fixed inside in advance, and a base having a hole for bolt fixing is installed in line with the hole for bolt fixing opened in the tray, the wiring is passed through the wire passing hole, the charging device is installed on top of the base and a bolt is inserted into the hole, and the tray is fixed with a nut from the underside or upper side of the tray, and the wiring is connected to the current collecting member.

[0018] The electric vehicle charging tray of the mechanical parking device according to the third aspect has a greater strength than a charging device body made of steel plate and can contribute to cost reduction.

[0019] According to the electric vehicle charging tray of the mechanical parking device of the fourth aspect, the charging device body and the tray are fixed with higher strength than in a tray that does not have a base on the upper surface of the tray.

[0020] The electric vehicle charging tray of the mechanical parking device of the fifth aspect reduces the risk of the charging plug connection part getting wet from moisture such as rainwater brought in by the vehicle, compared to a system in which the charging plug is inserted from above and connected.

[0021] According to the method for manufacturing or modifying an electric vehicle charging tray for a mechanical parking device of the sixth aspect, compared to methods that require complex processing of the tray, a tray for an electric vehicle with a charging device can be produced with simple operations without changing the tray production line, thereby suppressing cost increases. In addition, existing trays for non-electric vehicles can be modified into trays for electric vehicles with simple operations, and a mechanical parking device for non-electric vehicles can be converted into a mechanical parking device capable of charging electric vehicles.

Further, on the rear side of the tray 10, an entrance guide light that informs the user of the location of the vehicle when entering or leaving the parking lot, and a mirror that reflects the vehicle's position are installed.

[0026] 〔tray〕 1 and 2, the tray 10 in the first embodiment is a flat tray with a flat upper surface, and a plurality of charging devices 20 are installed at the corners of the tray 10. In this embodiment, a charging device 20 is provided at each of the four corners of the tray 10, but at least one charging device 20 may be provided, or two charging devices 20 may be provided at two diagonally opposite corners of the tray 10, and there is no restriction on the number of charging devices 20.

[0027] As shown in FIG. 7 , a current collecting member 18 is provided on the underside of tray 10, and a power supplying member (not shown) is provided on a rail member or frame member (not shown) along which tray 10 runs, and power for charging the electric vehicle is supplied to a charging plug connection portion 30 (described later) through contact between current collecting member 18 and the power supplying member (not shown).

[0028] <Main components> Here, the configuration of the main part will be described with reference to FIG. 3 to FIG.

[0029] [Charging device] As shown in Figures 3 to 5, the charging device 20 is configured to include a charging device main body 22 made of cast iron, and a charging plug connection portion 30 that is fixed inside the charging device main body 22 and includes wiring through which power is supplied.

[0030] [Charging device body] The charging device main body 22 is composed of an opening 24 for inserting a charging plug on the inward facing side of the tray 10, a back plate 23 for fixing the charging plug connection portion 30, a wiring hole 28 for passing wiring 34 of the charging plug connection portion 30 described later, and a hole for fixing a bolt (not shown).

[0031] The charging device main body 22 is fixed to the upper surface of the corner of the tray via a pedestal 26. Specifically, bolt fixing holes (not shown) are drilled in the steel plate constituting the bottom plate of the charging device main body 22, the pedestal 26, and the upper surface 12 of the tray 10, and the charging device main body 22 is fixed with bolts and nuts. The bottom plate of the charging device main body 22 also has a wire passing hole 28 through which wiring 34 of the charging plug connection part 30 described later passes, and together with the wire passing hole 16 drilled in the frame member 14 of the tray 10, the wiring 34 can be passed.

[0032] [Charging plug connection part] 6, charging plug connection section 30 is fixed to back plate 23 having a surface facing opening 24 of charging device main body 22, and charging plug 40 is inserted and connected through opening 24. Charging plug connection section 30 has a cover member 32 that is manually opened before charging plug 40 is inserted into opening 24, and is configured to be open only when charging plug 40 is inserted and connected, and to automatically close when charging plug 40 is pulled out by the biasing force of a spring built into a hinge.

[0033] [Charging plug] The charging plug 40 includes a charging plug cord 42 and a vehicle-side charging plug 44. A control unit (not shown) is provided on the charging plug cord 42. As shown in Fig. 7, the charging plug 40 is connected to the charging device 20, specifically, the charging plug connection unit 30, and the vehicle-side charging plug 44 is connected to a plug connection unit (not shown) on the vehicle side.

[0034] Second Embodiment Next, a second embodiment will be described with reference to Figures 8 to 11. In the second embodiment, the configuration of the charging device 20 is the same as that of the first embodiment, so the symbols in the first embodiment will be used, and new symbols will be assigned to parts of the tray that differ from the first embodiment.

[0035] In the second embodiment, the tray 110 is different from that in the first embodiment. As shown in Fig. 8 and Fig. 10, the tray 110 in this embodiment has rising portions 112 formed along the longitudinal direction of the tray 110 on both left and right edge portions of a plate member that forms the upper surface of the tray 110. Such a tray 110 is also referred to as a folded tray in contrast to the flat tray shown in the first embodiment, and the rising portions 112 are shaped to act as structural beams of the tray 110. For this reason, the rising portions 112 cannot be machined to have large openings or the like.

[0036] The charging device 20 is the same as in the first embodiment, so details will be omitted, but in the second embodiment, the mounting position of the charging device 20 is the upper surface of the rising portion 112 of the tray 110. Due to the difference in shape of the tray 110, the position of the frame member 114 is slightly different from that of the tray 10 in the first embodiment, and the steel material used is also a square steel pipe, so that the wiring 34 of the charging plug connection portion 30 can be wired without providing a wiring hole 16 in the frame member 114. The wiring 34 is connected to the current collecting member 18, as in the first embodiment.

[0037] [Function of main parts] Here, the operation of the main parts will be described. The operation of the main parts is similar between the first embodiment and the second embodiment, so they will be described together.

[0038] As shown in Figures 6 and 11, the charging device 20 has a built-in charging plug connection section 30, and the charging plug 40 is connected by inserting it through the opening 24 of the charging device main body 22 by opening a cover member 32 of the charging plug connection section 30. Meanwhile, as shown in Figure 7, the vehicle-side charging plug 44 is connected by being inserted into a plug socket (not shown) provided on the front or rear side surface of the vehicle 50. The power collected by the current collecting member 18 is supplied to the charging plug connection section 30 via wiring 34, and a battery (not shown) mounted on the vehicle 50 is charged via the vehicle-side charging plug 44.

[0039] The above has explained the configuration and function of the main parts, but the charging device 20 described in the first and second embodiments can naturally be installed on the trays 10, 110 of a newly installed mechanical parking device 1, but it can also be added to and modified on the trays 10, 110 of an existing mechanical parking device 1.

[0040] Specifically, the trays 10, 110 have a charging device 20 with a built-in charging plug connection portion 30 on the upper surface of at least one corner, a current collecting member 18 is provided on the underside of the trays 10, 110, and wire passing holes 16, 28 are provided in the frame members 14 of the trays 10, 110, through which wiring 34 that supplies power to the charging plug connection portion 30 can be passed. The charging device 20 has the charging plug connection portion 30 fixed inside in advance. A base 26 having a hole portion for bolt fixing (not shown) is installed in alignment with the hole portion for bolt fixing (not shown) opened in the trays 10, 110, the wiring 34 is passed through the wire passing holes 16, 28, the charging device 20 is installed on top of the base 26, a bolt is inserted into the hole portion, and the charging device 20 is fixed with a nut from the underside or upper side of the trays 10, 110, and the wiring is connected to the current collecting member 18, thereby enabling an existing mechanical parking device 1 for non-electric vehicles to be converted into a mechanical parking device 1 for electric vehicles.

[0041] In this way, the electric vehicle charging tray 10, 110 of the mechanical parking device of the present invention is a mechanical parking device 1 having an entrance / exit door 6 through which the vehicle 50 can enter and exit, and a floor 3 on which the tray 10, 110 on which the vehicle 50 is placed is movably arranged, and the tray 10, 110 is formed rectangular in a plan view and has a charging device 20 with a built-in charging plug connection part 30 on the upper surface 12, 112 (raised portion) of at least one corner thereof, and the charging device 20 has a charging device main body 22 formed approximately in a rectangular parallelepiped, has long sides in the longitudinal direction of the tray, and an opening 24 is formed on the side of the long side facing the inside of the tray, and the charging plug connection part 30 is fixed to the back panel 23 of the charging device main body 22 at a position corresponding to the opening 24, and is directly fixed to the upper surface 12, 112 of the corner of the tray 10, 110.

[0042] This makes it possible to manufacture trays 10, 110 for electric vehicles having charging devices with simple operations without modifying the tray manufacturing line, as compared with trays that require complex processing, thereby suppressing increases in costs.

[0043] In addition, the charging plug connection portion 30 has wiring 34 for supplying power, and the wiring 34 is passed through wiring holes 16, 28 formed in the charging device main body 22 and the frame members 14, 114 of the trays 10, 110, and is connected to a current collecting member 18 installed on the underside of the trays 10, 110.

[0044] This not only makes it possible to produce a tray for electric vehicles with a charging device with simple work compared to those that require complex processing of the tray, but it also makes it possible to convert existing trays for non-electric vehicles into trays 10, 110 for electric vehicles with simple work, and to convert a mechanical parking device for non-electric vehicles into a mechanical parking device 1 that can charge electric vehicles.

[0045] Furthermore, the charging device body 22 of the charging device 20 is manufactured by casting.

[0046] This allows charging device main body 22 to have greater strength than a steel can made from a steel plate, and also contributes to cost reduction.

[0047] The lower portion of the charging device 20 is fixed to the trays 10 and 110 via a base 26 .

[0048] This allows charging device main body 22 and trays 10, 110 to be fixed with greater strength than if the tray did not have a base on its upper surface.

[0049] The opening 24 is also positioned so that a charging plug 40 can be inserted from the side for connection.

[0050] This can prevent charging plug connection portion 30 from getting wet from rainwater or other moisture brought in by vehicle 50, as compared to a charging plug that is connected by being inserted from above.

[0051] In addition, in the method of manufacturing or modifying an electric vehicle charging tray for a mechanical parking device, the tray 10, 110 for the mechanical parking device is formed in a rectangular shape in a plan view, and has a charging device 20 with a charging plug connection portion 30 built in on an upper surface 12, 112 of at least one corner thereof, a current collecting member 18 is provided on the lower surface side of the tray 10, 110, and wiring 34 for supplying power to the charging plug connection portion 30 can be passed through frame members 14, 114 of the tray 10, 110. Wire passage holes 16, 28 are provided, and the charging device 20 has a charging plug connection portion 30 fixed inside. The base 26, which has a hole for bolt fastening, is installed in line with the hole for bolt fastening opened in the tray 10, 110, the wiring 34 is passed through the wire passage holes 16, 28, the charging device 20 is installed on top of the base 26 and a bolt is inserted into the hole, and the charging device 20 is fixed with a nut from the bottom or top side of the tray 10, 110, and the wiring 34 is connected to the current collecting member 18.

[0052] This allows electric vehicle trays 10, 110 with charging devices to be produced with simple operations without modifying the tray production line, compared to those that require complex processing of the trays, thereby preventing increases in costs. Also, existing non-electric vehicle trays can be easily converted into electric vehicle trays 10, 110, and a mechanical parking device for non-electric vehicles can be turned into a mechanical parking device 1 capable of charging electric vehicles.

[0053] Although the first and second embodiments of the present invention have been described above, the present invention is not limited to these, and it goes without saying that other aspects, modifications, or improvements of the present invention are included within the technical scope.

[0054] For example, on the floor 3 of the loading / unloading room 2, the front and rear sides in the loading direction of the trays 10, 110 may be decks made of steel plates instead of the floor (slab) of the structure. Depending on the model of the mechanical parking device, the relevant positions may be decks made of steel plates, and even in this case, the effect of the present invention can be fully exerted.

[0055] Further, the charging device 20 has been described as being directly fixed to the trays 10, 110 with the base 26 interposed therebetween, but this is not limiting, and the charging device 20 may be fixed to the trays 10, 110 without using the base 26.

[0056] Also, although the charging device main body 22 has been described as being a casting, it may be a canned product using a steel plate. In this case, the charging device main body 22 may be fixed to the trays 10 and 110 by welding without using bolts and nuts.

[0057] In addition, although it has been explained that the charging plug connection portion 30 is fixed to the back plate 23 of the charging device main body 22, this is not limited to the above, and the charging plug connection portion 30 may be fixed in advance to a bracket separate from the back plate 23, and the bracket may be attached to the charging device main body 22.
