Description

[Technical Field]

[0001] The present invention relates to a charging device for electric vehicles to be placed in a parking device, or to a parking device having a charging device for electric vehicles. [Background technology]

[0002] From the viewpoint of securing parking spaces, multi-level parking systems that park vehicles in a multi-level manner have become widespread. Multi-level parking systems have a pallet on which the vehicle is placed and a transport device that raises and lowers the pallet. Vehicles are parked on the pallet, and the transport device raises and lowers the pallet as needed. Meanwhile, with the recent spread of electric vehicles, it has become necessary to park electric vehicles in multi-level parking systems. Electric vehicles require charging while parked, so it has become necessary to charge electric vehicles in multi-level parking systems.

[0003] Unlike flat parking lots, charging an electric vehicle may require the pallet on which the electric vehicle is placed to be raised and lowered or moved left and right. Because a charging cable is required to charge an electric vehicle, the charging cable is placed on the pallet when charging the electric vehicle. However, there is a risk that the charging cable may protrude from the pallet and get caught on the transport device, causing the charging cable to break or the transport device to malfunction. To solve these problems with multi-level parking systems that allow charging electric vehicles, technologies such as those described in Patent Documents 1 to 7 are known.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The embodiment described below is an example of an embodiment of the present invention, and the present invention is not limited to these embodiments.

[0018] In the drawings referred to in this embodiment, identical parts or parts having similar functions are designated by the same or similar symbols (symbols consisting of a number followed by A, B, etc.). Also, for the sake of convenience, the dimensional ratios in the drawings may differ from the actual ratios, and some components may be omitted from the drawings. Note that ordinal numbers such as "first," "second," and "third" in this specification are used solely for the sake of simplicity and should not be interpreted in a limiting sense.

[0019] [Parking device configuration] Fig. 1 is a schematic side view of a parking device 1000 according to one embodiment of the present invention. Fig. 1 shows the main configuration of the parking device 1000 according to one embodiment of the present invention. Fig. 2 is a schematic front view of the parking device 1000 shown in Fig. 1.

[0020] The parking device 1000 has a main structure formed by support posts 1102, and a pallet 1001 on which a vehicle V is placed is installed within the main structure. A charging device 100 according to one embodiment of the present invention is installed on the pallet 1001.

[0021] Pallet 1001 is provided so as to be able to move up and down along support posts 1102 by elevator 1106. Pallet 1001 may also be able to move in the lateral direction of the vehicle body (the direction into the paper in FIG. 1).

[0022] Pallets 1001 in the main structure are spaced apart so that when multiple vehicles V are stacked vertically, they do not interfere with each other. As a result, the main structure formed by the support columns 1102 forms a parking space stacked vertically in multiple tiers.

[0023] Parking device 1000 is operated by control panel 1112 via control device 1110. Control panel 1112 is provided on the outside of parking device 1000. Figure 1 shows an example in which control panel 1112 is attached to a support 1102 near the entrance / exit gate of parking device 1000 (lower right side of the figure).

[0024] A user can operate the operation panel 1112 from outside the parking device 1000 to give instructions to the control device 1110, which can then move the desired pallet 1001 to the entrance / exit gate.

[0025] A gate 1108 provided at the entrance / exit of the parking device 1000 can be opened and closed by a control device 1110 through operation of an operation panel 1112 .

[0026] The gate 1108 is kept closed except when it is opened to allow the vehicle V to enter or leave the parking device. Therefore, the gate 1108 is kept closed when the pallet 1001 is moving. By keeping the gate 1108 closed, people are normally prevented from entering the parking device 1000.

[0027] In the parking device 1000, which forms parking spaces stacked vertically in multiple tiers and stores and parks vehicles V in a three-dimensional manner, the pallets 1001 are raised and lowered to move the desired pallet 1001 to the entrance and exit, allowing the vehicle to be loaded or unloaded.

[0028] There are several methods for moving the desired pallet 1001 to the entrance / exit gate. For example, there is a method in which the lower pallet 1001 is lowered into an underground pit in order to allow a vehicle parked on the upper pallet 1001 to leave the parking lot, a method in which the lower or upper pallet 1001 is slid laterally (in the depth direction of the paper in FIG. 1) to lower the upper pallet 1001 into a space where the lower pallet 1001 is not present, or a combination of these methods.

[0029] In Fig. 1, parking spaces PS1, PS2, PS3, and PS4 are provided from the first floor to the upper floors. In addition, parking space PS5 is provided to the side of parking space PS1 shown in Fig. 2, and parking space PS9 is provided further to the side of that.

[0030] Parking spaces PS1 to PS9 are each equipped with pallets 1001 with pallet numbers P1 to P9. In this case, when lowering the pallet 1001 in the upper parking space PS4 to allow vehicle V to enter or exit, the pallets 1001 in the lower parking spaces PS1, PS2, and PS3 become an obstacle. In this case, if the pallet 1001 in parking space PS9 is raised to the same height as the pallet 1001 in parking space PS8 and the pallets 1001 in parking spaces PS1 to PS3 and parking spaces PS5 to PS7 are slid laterally, the obstacle disappears and the pallet 1001 in parking space PS4 can be lowered to the entrance / exit gate.

[0031] [Charging device configuration] Fig. 3 shows a cross-sectional end view of a charging device 100 according to one embodiment of the present invention. Figs. 4 to 6 are schematic diagrams showing a method of installing a charging cable 10 in a charging device 100 according to one embodiment of the present invention.

[0032] The charging device 100 is a charging device placed on a pallet 1001 on which a vehicle V is parked, and includes a storage unit 110. The storage unit 110 is a housing capable of storing the cable 11 of the charging cable 10, and is placed on the pallet 1001. The storage unit 110 is made of a corrosion-resistant material or a material with an anti-rust coating, from the viewpoint of being installed outdoors. A cable 11a of sufficient length to connect the charging connector 15 to the vehicle V for charging is placed outside the storage unit 110, and the storage unit 110 stores the remaining length (excess) of the cable 11 up to the plug 13. Therefore, the capacity of the storage unit 110 is sufficient to store the excess cable 11b.

[0033] The accommodation portion 110 has a cutout portion 119 in which the cable 11 of the charging cable 10 can be placed. More specifically, the cutout portion 119 is arranged on the edge of the side surface of the accommodation portion 110. The cutout portion 119 forms a hole together with a lid portion 111 that is arranged on the accommodation portion 110 in an openable and closable manner. The cutout portion 119, i.e., the hole, has a diameter that allows the cable 11 of the charging cable 10 to be placed therein. Although the cutout portion 119 is shown as being semicircular or semielliptical in FIG. 3 , the shape of the cutout portion 119 is not particularly limited as long as the shape allows the cable 11 to be placed therein.

[0034] Furthermore, an outlet 113 for connecting the plug 13 of the charging cable 10 is provided inside the storage section 110. A cable 115 arranged outside the storage section 110 is connected to the outlet 113. A plug 117 is connected to the end of the cable 115. The plug 117 is connected to an outlet (not shown) arranged in the parking device 1000, and supplies power to the outlet 113 via the cable 115. Note that if the cable 115 is a cable that is directly pulled in from the parking device 1000, there is no need to provide the plug 117.

[0035] Furthermore, a cable fixing portion 150 is arranged inside the accommodation portion 110 to prevent excess cable 11b of charging cable 10 from being pulled out from the accommodation portion 110. Also, a detection portion (first detection portion) 155 is arranged inside the accommodation portion 110 to detect that first cable fixing portion 151 fixed to cable 11 is fixed to second cable fixing portion 153. First detection portion 155 controls the power supply to outlet 113.

[0036] The cable fixing part 150 can be any known means capable of fixing the cable 11 to the housing part 110, and is not particularly limited. For example, a ball catch, a magnetic catch, a cylinder key, or the like can be used as the cable fixing part 150, but is not limited to these. As an example, FIGS. 3 to 6 show an example in which a ball catch is used as the cable fixing part 150. As a modified example, FIG. 7(a) shows an example in which a magnetic catch is used as the cable fixing part 150, and FIG. 7(b) shows an example in which a cylinder key is used as the cable fixing part 150.

[0037] As shown in FIG. 3, the excess cable 11b is accommodated inside the accommodation portion 110, and a ball catch (male) (first cable fixing portion) 151 is connected to the cable 11 in order to fix the cable 11 to the accommodation portion 110 with the cable fixing portion 150. The position at which the first cable fixing portion 151 is connected to the cable 11 is a position that marks the boundary between the cable 11a, which is long enough to connect the charging connector 15 to the vehicle V for charging, and the excess cable 11b. A ball catch (female) (second cable fixing portion) 153 that can engage with the first cable fixing portion 151 is arranged in the accommodation portion 110 (FIG. 5(a)).

[0038] As shown in Figure 6, by connecting plug 13 to outlet 113 and inserting first cable fixing portion 151 into second cable fixing portion 153 (Figure 5(b)), first cable fixing portion 151 engages with second cable fixing portion 153 and cable 11 is fixed to storage portion 110. This allows cable 11b other than the length required for charging to be stored in storage portion 110, preventing breakage or damage to charging cable 10 due to charging cable 10 getting caught on parking device 1000 when pallet 1001 moves up and down or sideways.

[0039] At this time, the tip of the first cable fixing portion 151 comes into contact with the first detection unit 155, and the first detection unit 155 can detect that the cable 11 is fixed in the housing portion 110. The first detection unit 155 detects whether the cable 11 is fixed to the cable fixing portion 150 and controls the power supply to the outlet 113. For example, by electrically connecting the first detection unit 155 to the cable 115, it is possible to control the on / off of the power supply to the outlet 113. Alternatively, the charging device 100 may further include a control circuit 140 that controls the power supply to the outlet 113, and the on / off of the power supply to the outlet 113 may be controlled in response to a signal supplied from the first detection unit 155. Note that the function of the control circuit 140 may be included in the control device 1110 of the parking device 1000. That is, the control device 1110 may control the on / off of the power supply to the outlet 113 in response to a signal supplied from the first detection unit 155. When it is detected that the cable 11 is fixed to the cable fixing part 150, the first detection part 155 can supply power to the outlet 113. Because the dedicated first cable fixing part 151 is attached to the charging cable 10, charging cannot be performed with any other charging cable 10 than the pre-designated one. This makes it possible to prevent, for example, anyone other than the user from charging.

[0040] The first detector 155 may be any known means capable of detecting that the cable 11 has been fixed to the housing 110, and is not particularly limited to such means. For example, a microswitch or a cylinder key may be used as the first detector 155, but the first detector 155 is not limited to these. As an example, FIGS. 3 to 6 show an example in which a microswitch is used as the first detector 155. Furthermore, as a modified example, FIG. 7(a) shows an example in which a magnetic catch and a microswitch are combined as the first detector 155, and FIG. 7(b) shows an example in which a cylinder key is used.

[0041] In the cable fixing portion 150A shown in FIG. 7(a), the first cable fixing portion 151A and the second cable fixing portion 153A form a magnetic catch. A magnet is disposed on one of the first cable fixing portion 151A and the second cable fixing portion 153A, and a member made of iron or stainless steel is disposed on the other. The first cable fixing portion 151A is held by the second cable fixing portion 153A by magnetic force, and the cable 11 is fixed to the housing portion 110. At this time, the convex portion 152A disposed on the first cable fixing portion 151A comes into contact with the microswitch serving as the first detecting portion 155, so that the first detecting portion 155A can detect that the cable 11 has been fixed to the housing portion 110.

[0042] 7(b), the first cable fixing portion 151B and the second cable fixing portion 153B constitute a cylinder key. By inserting the first cable fixing portion 151B, which is a key, into the second cable fixing portion 153B, which is a cylinder, and rotating the first cable fixing portion 151B, the key is locked and the cable 11 is fixed to the housing portion 110. The second cable fixing portion 153B also functions as a first detecting portion 155B, and by locking the key, the first detecting portion 155B can detect that the cable 11 has been fixed to the housing portion 110.

[0043] In one embodiment, the charging device 100 may further include a holding portion 123 that holds the cable 11b housed inside the housing portion 110. The holding portion 123 is a known means capable of bundling and holding the cable 11b. In one embodiment, as shown in FIG. 6 , the holding portion 123 may be configured to be able to be arranged on the plate 120. In this embodiment, the plate 120 is arranged inside the housing portion 110 and connected to the lid portion 111 via an arm 121. The position of the plate 120 can be changed in the up-down direction of the housing portion 110 in conjunction with the opening and closing of the lid portion 111. Specifically, when the lid portion 111 is opened, the arm 121 connected to one end of the plate 120 lifts up one end of the lid portion 111. As a result, the holding portion 123 is also lifted up to the opening of the housing portion 110, facilitating the operation of holding the cable 11b in the holding portion 123 and the operation of removing the cable 11b from the holding portion 123.

[0044] Furthermore, when the lid 111 is closed, the arm 121 connected to one end of the plate 120 presses down one end of the lid 111. This also presses down the holding portion 123 to the bottom of the storage portion 110, allowing the cable 11b to be stored in the storage portion 110.

[0045] In one embodiment, the charging device 100 may further include a second detection unit 160 that detects whether the lid 111 is open or closed. The second detection unit 160 can control the power supply to the outlet 113 depending on whether the lid 111 is open or closed. In one embodiment, the second detection unit 160 may detect whether the lid 111 is closed by sensing the proximity or contact of the plate 120. The second detection unit 160 may be any known means capable of detecting the open or closed state of the lid 111, including, but not limited to, a switch pressed by the plate 120, a limit switch, a magnetic switch, and a proximity switch. The second detection unit 160 detects whether the lid 111 is closed and controls the power supply to the outlet 113. For example, by electrically connecting the second detection unit 160 to the cable 115, the power supply to the outlet 113 can be turned on and off. Alternatively, charging device 100 may further include a control circuit 140 that controls the power supply to outlet 113, thereby controlling the on / off of the power supply to outlet 113 in response to a signal supplied from second detection unit 160. Note that the function of control circuit 140 may be included in control device 1110 of parking device 1000. In other words, control device 1110 may control the on / off of the power supply to outlet 113 in response to a signal supplied from second detection unit 160.

[0046] In the present embodiment, when first detector 155 detects that cable 11 is fixed to cable fixing portion 150 and second detector 160 detects that lid portion 111 is closed, control is performed so that power is supplied to outlet 113. As a result, power is supplied to charging cable 10 only when cable 11 is fixed to cable fixing portion 150, making it possible to prevent forgetting to fix cable 11. Furthermore, power is supplied to outlet 113 only when lid portion 111 is closed, making it possible to prevent electric shock when plugging plug 13 into outlet 113. In the present embodiment, a double safety measure can be realized using two conditions: that cable 11 is fixed and that lid portion 111 is closed.

[0047] In one embodiment, a holder 131 for engaging the charging connector 15 is arranged on a surface of the lid 111 facing inward of the storage section 110. The holder 131 may be made of, for example, an insulating member having a structure that can be fitted with the charging connector 15.

[0048] [Charging device variation 1] 8 is a cross-sectional end view showing a modified charging device 100A in which holder 131A for engaging charging connector 15 is arranged on the outside of lid portion 111. The other configuration inside storage portion 110 is the same as that of charging device 100, and therefore detailed description will be omitted. In charging device 100A, charging connector 15 is engaged with holder 131A arranged on lid portion 111, which prevents charging cable 10 from being left on pallet 1001 and breaking. In addition, it is possible to prevent inadvertent current flow and leakage from charging connector 15.

[0049] [Charging device variation 2] FIG. 9 is a cross-sectional end view of charging device 100B in which holder 131B is arranged on support 133 instead of lid 111. Other configurations within storage section 110 are the same as those of charging device 100, and detailed description thereof will be omitted. Support 133 is arranged in storage section 110, and holder 131B is arranged on support 133. In charging device 100B, charging connector 15 is engaged with holder 131B arranged on support 133 to store charging cable 10, thereby preventing inadvertent current flow and leakage from charging connector 15. Furthermore, because holder 131B is arranged on support 133, unlike when holder 131B is arranged inside storage section 110, charging connector 15 can be attached to and detached from holder 131B in a large space. Note that support 133 may be arranged on pallet 1001 instead of storage section 110.

[0050] [Placement of charging equipment on pallet] The placement of the charging port of an electric vehicle varies depending on the manufacturer and model. Therefore, in order to prevent the charging cable 10 from breaking or getting caught on something while charging the vehicle V, the charging device 100 needs to be placed near the charging port of the vehicle V. On the other hand, the charging device 100 needs to be placed in a position where it does not interfere with the opening and closing of the door of the vehicle V.

[0051] 10(a) is a front view of a pallet 1001 on which a charging device 100 according to one embodiment of the present invention is arranged, and FIG. 10(b) is a top view of the pallet 1001. FIG. 10(b) shows four positions 100a to 100d at which the charging device 100 can be arranged on two opposing sides of the pallet 1001. Generally, the charging port of an electric vehicle is arranged on the left and right side of the rear of the vehicle V (where a fuel filler port is generally arranged) or on the front of the vehicle V. For this reason, the charging device 100 is arranged on the pallet 1001 at a position near the left and right side of the rear of the vehicle V or at a position near the left and right front of the vehicle V.

[0052] Although one embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the present invention. For example, a parking device according to the present embodiment can be modified by a person skilled in the art by adding, deleting, or modifying components as appropriate, and the modifications are within the scope of the present invention as long as they incorporate the gist of the present invention. Furthermore, the above-described embodiments can be combined as appropriate as long as they are not mutually inconsistent, and technical matters common to each embodiment are included in each embodiment even if not explicitly stated.

[0053] Even if there are other effects and advantages different from those brought about by the aspects of each of the above-mentioned embodiments, those that are clear from the description in this specification or that can be easily predicted by a person skilled in the art are naturally understood to be brought about by the present invention.
