Description

Technical Field

[0001] The present invention relates to an electric vehicle charging tray and a mechanical parking device using the same.

Background Art

[0002] In recent years, electric vehicles have begun to spread in automobiles. Electric vehicles include those purely driven by a battery and a motor, called battery electric vehicles (BEVs), and those that use an internal combustion engine, a battery, and a motor in combination, such as plug-in hybrid vehicles (PHEVs) that can charge the battery from external charging facilities. There are automobiles that require battery charging.

[0003] Regarding battery charging, there are vehicle models that can perform rapid charging in addition to general charging. However, in any case, since battery charging takes a long time, there is an increasing demand for mechanical parking devices equipped with facilities that can charge during parking.

[0004] In view of such circumstances, a tray 220 for an electric vehicle as shown in FIG. 18 has conventionally existed. The tray 220 for an electric vehicle is provided with a power supply unit 25 for charging. However, for charging the vehicle, the power supply lid must be opened when inserting the charging cable into the power supply port of the vehicle 40. In order to prevent the open power supply lid from protruding from the edge of the tray 220, the width dimension of the second rising portion 222 on one side in the width direction of the tray 220 must be made larger than the width dimension of the first rising portion 221 on the other side.

[0005] For example, Patent Document 1 describes a charging pallet having a power supply relay unit for charging an electric vehicle equipped with a charging port. The charging pallet is provided with guiding means for guiding the vehicle to be charged so that when the lid of the charging port of the electric vehicle is opened, the vehicle is moved to the side of the reverse charging port at a distance where it does not protrude laterally from the pallet when the vehicle enters the charging pallet for the electric vehicle.

[0006] In addition, Patent Document 2 describes a charging pallet having a power supply relay unit for charging an electric vehicle equipped with a charging port. When the electric vehicle enters the charging pallet, the charging pallet is provided with a guiding and guiding unit that offsets the electric vehicle toward the reverse charging port side at a distance that does not protrude to the side of the pallet when the lid of the charging port is open, and allows the vehicle to enter the roadway. A charging pallet is described.

[0007] In addition, Patent Document 3 describes a wheel guiding device that is detachably attached to a wheel guiding wall erected on a side edge of a pallet on which a vehicle is placed. A guiding side wall that is parallel to the wheel guiding wall and is separated from the wheel guiding wall by a predetermined distance toward the center side in the width direction of the pallet, and a front-rear movement restricting means for restricting the guiding side wall from moving in the front-rear direction with respect to the wheel guiding wall, and a left-right movement restricting means for restricting the guiding side wall from moving in the left-right direction with respect to the wheel guiding wall are provided. A wheel guiding device for a mechanical parking lot is described.

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, the charging pallet described in Patent Document 1 has rising side edges 20a, 20a on the outer sides in the width direction of two rows of vehicle lanes 20c, and the offset guiding means 22 is fixed inside one of the rising side edges 20a to correspond to the open state of the charging port lid 81 of the charging port 80 of the electric vehicle EV. This offset guiding means 22 is composed of a long guiding body 23 extending over substantially the entire length of the vehicle lane 20c and tip protection members 24 at the front and rear ends thereof, and is configured to guide and guide the electric vehicle EV to the other side of the charging pallet 20. However, in order to drive the electric vehicle EV onto the charging pallet 20, it must be parked in advance on the side of the rising side edge 20a where there is no offset guiding means 22. However, when the electric vehicle EV enters the charging pallet 20 while being offset in the direction where the offset guiding means 22 exists with respect to the charging pallet 20, since the tip protection member 24 is tapered and curved and reduced, there is a possibility that the tire of the electric vehicle EV rides up from the tip protection member 24 to the guiding body 23, and the electric vehicle EV cannot be reliably guided. In particular, when the electric vehicle EV turns and stops with respect to the charging pallet 20 and then gets on, even if the front wheels pass normally, there is a possibility that the rear wheels ride up from the tip protection member 24 to the guiding body 23, and sufficient guiding cannot be achieved in this case either. Further, since the space between the rising side edge 20a of the charging pallet 20 and the offset guiding means 22 is narrow over the entire length of the charging pallet 20, it is necessary to adjust the electric vehicle EV to fit into the narrow vehicle lane 20c from the time of getting on the charging pallet 20.

[0010] Further, the charging pallet described in Patent Document 2 is similar to the charging pallet described in Cited Document 1, but has a rising side edge 23 on the outer side in the width direction of the vehicle lane 26, and the dimension in the width direction is wider than that of the rising side edge 24 on the side of the vehicle lane 27. However, in this case as well, there is a possibility that the inconvenience that occurs when the electric vehicle EV gets on the charging pallet 20 described in Cited Document 1 may occur, and there may be a case where the electric vehicle EV cannot be reliably guided and guided in a direction away from the rising side edge 23. Further, similar to the invention disclosed in Cited Document 1, since the portion of the vehicle lane 27 is narrow over the entire length of the charging pallet 20, it is necessary to adjust the electric vehicle EV to fit into the narrow vehicle lane 27 from the time of getting on the charging pallet 20.

[0011] In addition, in the wheel guiding device of the mechanical parking lot described in Patent Document 3, the wheel guiding device 11 is provided on one inner surface of a pair of left and right wheel guiding walls 16 of the pallet 5. Although guide inclined surfaces 27 are provided at both ends of the wheel guiding device 11, when the electric vehicle approaches and gets on the side of the wheel guiding device 11, it may get on the wheel guiding device 11 or the wheel guiding wall 16. In particular, even when the electric vehicle gets on obliquely with respect to the pallet 5 and the front wheels are pulled by the guide inclined surface 27 and guided into the wheel guiding groove 17, the rear wheels may get on from the guide inclined surface 27 to the wheel guiding device 11. Further, since the wheel guiding device 11 is provided over the entire length of the pallet 5, as in the inventions disclosed in Cited Documents 1 and 2, it is necessary to adjust the electric vehicle to fit into the narrow road from the time of getting on the pallet 5.

[0012] An object of the present invention is to provide a tray on which, even when an electric vehicle gets on while leaning left and right with respect to the tray, the front wheels are guided so that the rear wheels are guided in the guiding direction to correct the position of the electric vehicle on the tray, and each device at the time of charging fits within the width of the tray.

Means for Solving the Problems

Mode for Carrying Out the Invention

[0026] An example of a vehicle guiding device of a mechanical parking apparatus according to the present embodiment will be described with reference to the drawings. In addition, the direction in which the operation panel is provided with respect to the tray is expressed as "right", the opposite side is expressed as "left", the side of the entrance / exit door 4 is expressed as "front", and the opposite side is expressed as "rear". Further, although the vehicle 40 is an electric vehicle, in the present invention, not only a pure electric vehicle (BEV) that runs only with a battery and a motor, but also a plug-in hybrid vehicle (PHEV) that runs using a combination of an internal combustion engine, a battery, and a motor is included.

[0027] <First Embodiment> [Configuration of Main Part] The configuration of the main part will be described with reference to FIGS. 3 to 6.

[0028] [Electric Vehicle Charging Tray] As shown in FIGS. 3 to 5, the electric vehicle charging tray 20 in the first embodiment includes a pair of left and right vehicle lanes 23 on which the vehicle 40 is placed, and rising portions 21 and 22 formed on the outer sides in the width direction of each of the vehicle lanes. The rising portions 21 and 22 include a first rising portion 21 formed with a constant width in the approaching direction of the vehicle 40, an entrance portion 22A on the front side of the approaching direction of the vehicle 40 toward the approaching direction of the vehicle 40, and a vehicle guiding portion 22B that is continuous with the entrance portion 22A and gradually widens from the middle. The second rising portion 22 is formed parallel to the approaching direction of the vehicle 40 with a wide width from the end of the vehicle guiding portion 22B. The roller portion 30 is located on the front side of the approaching direction of the vehicle 40 with respect to the vehicle guiding portion 22B of the vehicle lane 23 and has a plurality of freely rotatable rollers 32 having a rotation axis 33 along the approaching direction of the vehicle 40 on both of the pair of vehicle lanes 23.

[0029] Also, since the charging positions in the vehicle 40, that is, the positions of the power supply covers 43 (see FIGS. 12 and 13), vary between the first rising portion 21 and the second rising portion 22 in the electric vehicle charging tray 20, a plurality of products manufactured by swapping the left and right may be prepared.

[0030] As shown in FIG. 3, a power supply unit 25 for supplying charging power to the vehicle is provided on the back side in the traveling direction of the vehicle 40 of the vehicle guiding portion 22B. When the second rising portion 22 is located on the right side of the tray, the power supply unit 25 is also arranged on the second rising portion 22.

[0031] [Roller portion] As shown in FIGS. 3 to 5, the roller unit 30 has a plurality of freely rotatable rollers 32 having a rotation axis 33 in the vehicle entry direction on both of the pair of vehicle paths 23 of the electric vehicle charging tray 20. The plurality of rollers 32 are supported by a roller support 31, and the roller support 31 is fixed to an opening 26 formed in the vehicle path 23. Specifically, as shown in FIG. 5, the roller support 31 is inserted into the opening 26, and bolts 34 fixed to both side surfaces of the roller support 31 are supported by a receiving member 27 fixed to the edge of the opening 26 and fixed by nuts 35. Further, the front and rear ends of the roller support 31 in the longitudinal direction are fixed to the bone member 28 of the electric vehicle charging tray 20. A plurality of these bolts are provided in the vehicle entry direction (longitudinal direction) of the electric vehicle charging tray 20 and have a structure capable of withstanding the weight of the vehicle.

[0032] Also, as shown in FIG. 5, a roller level L2, which is the rotation top of the roller 32, slightly protrudes from a boarding level L1, which is the upper surface of the vehicle path 23. In this embodiment, the protruding height h is adjusted within a range of 5 to 15 mm. Also, in FIG. 5, five rollers 32 are shown, but the rollers 32 themselves may have a small diameter and may be arranged in multiple rows, such as eight or ten. This enables stable guidance in the width direction when a vehicle with low air pressure in the tires, particularly the rear tires, enters.

[0033] [Operation of the main part] Here, the operation of the main part will be described with reference to FIGS. 6 to 13.

[0034] FIGS. 6 and 7 show a state in which the vehicle 40 is entering the electric vehicle charging tray 20 while being closer to the second rising part 22 with respect to the tray width direction. The power supply lid 43 of the vehicle 40 is on the left rear fender side of the vehicle 40 (see FIG. 12). As shown in FIG. 6, the front wheels 41 of the vehicle 40 are passing through the roller unit 30 and entering toward the vehicle guiding unit 22B. At this time, in this embodiment, the rear wheels 42 are located near the tire guide 6. As shown in FIG. 7, the front and rear wheels will travel on the rollers 32 of the roller unit 30.

[0035] Next, FIGS. 8 and 9 show a state where the vehicle 40 enters the electric vehicle charging tray 20 while approaching the second rising portion 22 in the tray width direction, the left front wheel 41 contacts the vehicle guiding portion 22B, and the user notices that the vehicle 40 is leaning to the left and turns the steering wheel slightly to the right, and continues to enter while the left front wheel 41 moves in a direction away from the vehicle guiding portion 22B. Since the front portion of the vehicle 40 has started to be guided to the right, the rear wheel 42 has started to be guided to the right on the roller 32. FIG. 9 shows that the rear wheel 42 has started to be guided to the right on the roller 32 and is moving away from the entrance portion 22A of the second rising portion 22.

[0036] Next, FIGS. 10 and 11 show a state where the vehicle 40 passes through the vehicle guiding portion 22B and enters along the second rising portion 22 of the electric vehicle charging tray 20, and the front wheel 41 is positioned at the wheel stopper 24. In this state, the rear wheel 42 is further moved to the right on the roller 32, that is, toward the first rising portion 21, the side where the power supply lid 43 of the vehicle 40 is located moves away from the end in the tray width direction, and the left side of the vehicle 40 becomes wider. As shown in FIG. 11, it can be seen that the rear wheel 42 on the left side of the vehicle 40 has moved away from the vehicle guiding portion 22B of the second rising portion 22 and is moving toward the first rising portion 21.

[0037] Then, as shown in FIGS. 12 and 13, the vehicle 40 can enter along the second rising portion 22 in the electric vehicle charging tray 20. Since the left side of the vehicle 40 becomes wider with respect to the electric vehicle charging tray 20, even if the power supply lid 43 of the vehicle 40 is opened and the tray-side charging plug 44 of the charging cable 46 and the vehicle-side charging plug 45 are connected, these charging appliances and the power supply lid 43 do not protrude from the end in the width direction of the electric vehicle charging tray 20.

[0038] <First Modified Example> The first modification example is shown in FIG. 14. As shown in FIG. 14, in the first modification example, a plurality of roller portions 130 are divided in the vehicle entry direction. In this first modification example, the roller portion 130 is divided into three parts in the vehicle entry direction (the longitudinal direction of the tray). In FIG. 14, for the sake of technical understanding, the divided roller portions 130 are described with a certain distance between them, but the actual separation dimension between the roller portions 130 is manufactured in such a way that the front or rear wheels of the vehicle ride on the roller 132. By dividing in this way, the roller portion 130 becomes smaller, so the manufacturing work of the electric vehicle charging tray 20 becomes simpler and the safety increases.

[0039] <Second Embodiment> Next, the second embodiment will be described with reference to FIGS. 15 and 17.

[0040] As shown in FIG. 15, the electric vehicle charging tray 120 is a flat tray with the entire upper surface of the tray being flat. Since the functions of the roller portion 30 and the roller 32 are the same as those in the first embodiment, the description thereof is omitted. [Rising Portion] Different from the first embodiment, the rising portion 122 is provided from near the approximate center in the vehicle entry direction of the electric vehicle charging tray 120 toward the back side. The rising portion 122 has a circular inlet portion at the tip on the rear side in the vehicle entry direction, and continuously from the inlet portion, a vehicle guiding portion 122B is formed, and from the end of the vehicle guiding portion 122B, it is formed in parallel with the vehicle entry direction while being wide. Also in the second embodiment, corresponding to the vehicle 40 with the power supply lid 43 on the right side, the rising portion 122B may be provided on the right side. Since the function of the rising portion 122B is the same as that in the first embodiment, the description thereof is omitted.

[0041] <Second Modification Example> The second modification example is shown in Fig. 16. As shown in Fig. 16, in the second modification example, a plurality of roller units 130 are divided in the vehicle 40's entry direction. In this second modification example, the roller unit 130 is divided into three parts in the vehicle 40's entry direction (the longitudinal direction of the tray). In Fig. 16, for the sake of technical understanding, the divided roller units 130 are described with a certain distance between each other, but the actual separation dimension between the roller units 130 is manufactured in such a way that the front or rear wheels of the vehicle ride on the roller 132. By dividing in this way, the roller unit 130 becomes smaller, so the manufacturing work of the electric vehicle charging tray 120 becomes simpler and the safety increases.

[0042] <Mechanical parking device> [Overall configuration of the storage and retrieval room of the mechanical parking device] Fig. 1 shows an example of the storage and retrieval room 2 of the mechanical parking device of the present invention. As shown in Fig. 1, the storage and retrieval room 2 of the mechanical parking device 1 is formed as a substantially rectangular housing as the building 1A, and includes an entrance / exit door 4 through which the vehicle 40 can enter and exit, and a floor 3 on which a tray 20 for placing the vehicle 40 is movably arranged. In Fig. 1, it is shown as a figure in which the electric vehicle charging tray 20 used in this embodiment is arranged, but a normal tray (not shown) for placing non-charging vehicles is also movably arranged. Further, on both sides of the floor 3 in the tray width direction on the storage side of the electric vehicle charging tray 20, tire guides 6 for guiding the front or rear wheels so that they do not get on the tray are arranged.

[0043] Also, on the right side of the entrance / exit door 4, an operation panel 5 for performing the entry / exit operation of the vehicle 40 is installed. The operation panel 5 includes a touch panel type display unit for guiding the user to perform the entry / exit operation and giving instructions for entry / exit, and an open button and a close button for opening and closing the entrance / exit door 4. Further, on the back side of the tray 20, an in-storage guide lamp for notifying the user of the position of the vehicle when the vehicle enters and exits and a mirror 8 in which the position of the vehicle is reflected are installed. Also, at a position corresponding to the front wheel position of the vehicle 40 on the floor 3, a front wheel position detection device 7 for detecting that the front wheel is located inside the wheel stopper 24 (see Fig. 3) is provided.

[0044] In this embodiment, as shown in FIG. 2, the storage room 9 is located below the loading and unloading room 2 and has storage compartments formed in a plurality of rows and a plurality of tiers. The storage compartments and the loading and unloading room 2 are connected by an elevator shaft 10. The elevator shaft 10 includes an elevator column 11, a lifting body 12 for lifting the electric vehicle charging tray 20 or a tray for a normal non-electric vehicle, and a lifting drive unit 13 for lifting the lifting body 12.

[0045] For this mechanical parking device 1, charging of the electric vehicle can be performed in the storage room 9 using the electric vehicle charging tray 20 described in the first embodiment or the electric vehicle charging tray 120 described in the second embodiment. In this case, the roller 32 is in a freely rotatable state so as to laterally displace the position of the vehicle 40 when placed on the lifting body 12 and landed in the loading and unloading room 2. However, when the lifting body 12 descends in the elevator shaft 10, a roller locking device (not shown) operates to stop the rotation of the roller and prevent lateral displacement of the vehicle 40 to the left and right.

[0046] The electric vehicle charging tray 20 or 120 may be about half the number of vehicles that can be accommodated in the mechanical parking device 1, and the remaining number may be a normal tray for non-charging vehicles. Also, since the position of the power supply lid 43 on the vehicle 40 is divided into the left side and the right side, the second rising portion 22 or the rising portion 122 can be prepared as the left side one and the opposite right side one as shown in the figure, respectively, so that the mechanical parking device can flexibly correspond to different types of electric vehicles.

[0047] As described above, the electric vehicle charging tray 20 according to the present invention includes a pair of left and right vehicle lanes 23 on which the vehicle 40 is placed, and rising portions 21 and 22 formed on the outer sides in the width direction of each of the vehicle lanes 23. The rising portions 21 and 22 include a first rising portion 21 formed with a constant width in the approaching direction of the vehicle 40, an entrance portion 22A on the front side of the approaching direction of the vehicle 40 toward the approaching direction of the vehicle 40, and a vehicle guiding portion 22B that is continuous with the entrance portion 22A and gradually widens from the middle. The second rising portion 22 is formed parallel to the approaching direction of the vehicle 40 with a wide width from the end of the vehicle guiding portion 22B. On the front side of the approaching direction of the vehicle 40 with respect to the vehicle guiding portion 22B of the vehicle lane 23 and on both of the pair of vehicle lanes 23, there is a roller portion 30 having a plurality of freely rotatable rollers 32 having a rotation axis 33 along the approaching direction of the vehicle 40.

[0048] Accordingly, compared with a tray without rollers, even if the vehicle approaches while leaning left and right with respect to the width direction of the tray, it is possible to suppress the power supply lid 43 of the vehicle 40 from protruding from the width direction end of the electric vehicle charging tray 20. In addition, since the entrance side of the tray is set wide, there is freedom in the lateral boarding position of the vehicle, making it easy to board the tray and minimizing the possibility of getting onto the vehicle guiding portion or the rising portion.

[0049] Further, the plurality of rollers 32 are supported by a roller support 31, and the roller support 31 is fixed to an opening 26 formed in the vehicle lane 23.

[0050] Accordingly, compared with directly installing a plurality of rollers on the tray, the plurality of rollers 32 can be fixed to the electric vehicle charging tray 20 as a component in which the plurality of rollers 32 are incorporated in the roller support 31 in advance, thereby reducing the manufacturing cost and improving the maintainability.

[0051] In addition, each of the plurality of rollers 32 is installed as a single unit or divided into a plurality of units in the approaching direction of the vehicle 40.

[0052] As a result, compared with a device using a large number of short rollers, the guidance on the rear side of the vehicle is stabilized, and the rear side of the vehicle 40 can be guided in conjunction with the guidance of the front wheels by the vehicle guiding portion 22B.

[0053] Further, the rotating top of the roller 32 slightly protrudes from the upper surface of the roadway 23.

[0054] As a result, compared with a device having a lower or higher protruding amount of the rotating top of the roller than the upper surface of the tray, the guidance on the rear side of the vehicle 40 is stabilized.

[0055] Moreover, an electric vehicle charging tray 120 is configured to include a pair of roadways 23 whose entire upper surface is flat and on which the vehicle 40 is placed. On the outer side in the width direction of one of the roadways 23, toward the entering direction of the vehicle 40, there are an entrance portion formed at the central portion in the entering direction of the vehicle 40, and a vehicle guiding portion 122B that is continuous with the entrance portion and gradually widens from the middle. The vehicle guiding portion 122B has a rising portion 122 formed parallel to the entering direction of the vehicle while remaining wide from the end, and a roller portion 30 having a plurality of freely rotatable rollers 32 having a rotation axis 33 along the entering direction of the vehicle 40 on both of the pair of roadways 23 on the front side of the entering direction of the vehicle with respect to the vehicle guiding portion 122B of the roadway 23.

[0056] As a result, compared with a flat tray without rollers, even if the vehicle 40 enters while leaning left and right with respect to the width direction of the tray, it is possible to suppress the power supply lid 43 of the vehicle 40 from protruding from the width direction end of the electric vehicle charging tray 120. Further, since the upper surface of the tray is flat, there is freedom in the left - right boarding position of the vehicle, making it easy to board the tray and minimizing the possibility of riding onto the vehicle guiding portion or the rising portion.

[0057] Further, the mechanical parking device 1 includes an entrance / exit room 2 where a tray on which the vehicle 40 is placed is arranged and the vehicle 40 enters and exits through the entrance / exit door 4, a storage room 9 placed and stored on the tray, and the electric vehicle charging trays 20 and 120 according to claim 1 or claim 5.

[0058] By having the electric vehicle charging trays 20 and 120 with the total number of accommodated units or a preset number of units, it is possible to accommodate both electric vehicles and non-electric vehicles, and smoothly guide the position of the vehicle 40 in the width direction of the tray.
