Description

The present invention relates to a two-stage parking system having a function of charging an EV vehicle.

Two-level parking systems can be roughly divided into above-ground types, in which parking spaces are provided only above ground, and pit-types, in which parking spaces are provided above ground and underground. In both the ground type and the pit type, vehicles are loaded and unloaded by directly loading onto a pallet located at the loading/unloading height (FL), or by leaving the vehicle on a pallet at the loading/unloading height. be exposed.
The two-stage parking device parks a vehicle by raising and lowering or moving a pallet across the parking space to provide two or more parking spaces in the same installation space.

In recent years, EV vehicles (electric vehicles) using an electric motor as a power source have become popular instead of gasoline vehicles. EV vehicles are good for the environment because they reduce exhaust gas, but they require charging batteries with electricity instead of refueling with gasoline. Therefore, a mechanical parking device with a charging function has been developed that charges an EV vehicle using the time stored in the mechanical parking device. In such a mechanical parking device with a charging function, for example, the pallet on which the EV vehicle is mounted is equipped with a charging stand for power supply, and by connecting the charging stand and the EV vehicle with a charging cable when entering the parking lot, the EV vehicle can be Vehicles can be charged.
A two-stage parking device equipped with a pallet that can charge such an EV vehicle is disclosed in, for example, Patent Document 1.

The two-stage parking device disclosed in Patent Document 1 supplies power to the charging stand by connecting a predetermined position on the frame body side and the charging stand set up on the pallet with a power cable having a predetermined slack. are doing. This "predetermined position on the frame body side" is a control panel fixed to the outside of the pallet in plan view in the case of a pallet that is to be raised and lowered, and in the case of a pallet that is to be moved horizontally, both ends are placed on the wiring duct that extends to the left and right of the frame body. This is the control panel.

JP2010-95848A

In the above-mentioned two-stage parking device of Patent Document 1, one end of the power cable is fixed to the frame body outside the outer edge of the pallet, so the power cable hangs down outside the outer edge of the pallet. This could cause the power cable to interfere with neighboring pallets or vehicles.

In addition, it is necessary to secure a space to accommodate the control panel fixed to the frame body and the loose power cable, so the control panel and loose power cable occupy the installation space required to park one vehicle. The problem was that it had to be made larger. Therefore, the two-stage parking device of Patent Document 1 requires a larger installation area than the two-multistage parking device without the function of charging an EV vehicle.

The present invention was devised to solve the above-mentioned problems. That is, an object of the present invention is to provide a two-stage parking device with a charging function that can be installed in a smaller installation area than the conventional two-multi-stage parking device with a charging function for EV vehicles.

According to the present invention, there is provided a two-stage parking device with a charging function, in which two or more stages of parking spaces are provided in the same installation space,
A pallet that moves up and down between the entry and exit height at which EV vehicles enter and exit the warehouse and the parking space above it;
a rear beam extending in the width direction of the pallet above the rear end of the pallet;
a charging stand that is erected at the end of the pallet and has a charging outlet that supplies power to the EV vehicle;
A power cable for supplying power to the charging stand,
The power cable has a hanging part that hangs down from the rear beam, and a stand-side end thereof connects to the charging stand,
The length of the hanging portion includes an extra cable length that allows the pallet to be raised and lowered,
A two-stage parking device with a charging function is provided, in which the hanging portion hangs down from the rear beam at a position between both ends of the pallet in the width direction.

According to the above-described embodiment of the present invention, the power cable hangs down from the rear beam, and the end thereof on the stand side has a hanging part that connects to the charging stand, and the hanging part extends in the width direction of the pallet in the width direction. It hangs down from the rear beam between the two ends. As a result, no matter where the pallet is located in the vertical direction, the hanging portion of the power cable does not protrude outside the outer edge of the pallet. That is, in the two-stage parking device of this embodiment, there is no need to secure extra space outside the pallet when viewed from above to accommodate the hanging portion of the power cable.
Therefore, since no space is required outside the pallet to install the hanging portion of the power cable, the two-stage parking system of this embodiment can park one vehicle more easily than the conventional two-stage parking system. The space required can be reduced. In other words, the two-stage parking device of this embodiment can be installed in the same installation area as the two-stage parking device without the function of charging an EV vehicle.

FIG. 1 is a plan view of a two-stage parking device with a charging function according to the present invention. 3 is a view taken along the line AA in FIG. 2. FIG. FIG. 3 is a view taken along the line AA in FIG. 2 when loading and unloading pallets on the 4th floor. It is an explanatory view of a cable protection cover.

Embodiments of the present invention will be described below based on the drawings. Note that common parts in each figure are given the same reference numerals, and redundant explanation will be omitted.

FIG. 1 is a front view of a two-stage parking device 100 with a charging function (hereinafter simply referred to as “two-stage parking device 100”) according to the present invention.
In this example, the two-stage parking device 100 is a 5-stage, above-ground, up-and-down type parking system in which parking spaces for vehicles in five stages (1F, 2F, 3F, 4F, and 5F) are provided in the same installation space.

In this example, the two pallets 2 located on the 1st floor among the 5 stages can be moved horizontally, and the pallets 2 located each on the 2nd, 3rd, and 4th floors can be moved horizontally and moved up and down, and the pallets 2 located on the 5th floor can be moved horizontally. The three pallets 2 located at can only be moved up and down.
Therefore, in this example, the number of vehicles 1 accommodated is 3×5−4=11.

In this example, the triple two-stage parking device has three entry/exit sections in installation spaces A, B, and C. The overall width of the pallets 2 is preferably the same, but may be different. In each of the storage spaces A, B, and C, three pallets 2 are located adjacent to each other with a necessary gap (for example, 40 mm or less) in between.

The two pallets 2 located on the 1st floor have wheels 6a at both ends in the length direction, and are horizontally moved along two horizontal rails 8a provided on the 1st floor by a horizontal drive device (not shown) to reduce the installation space. The vehicle 1 is directly entered and exited from one of the entry and exit sections A, B, and C. Hereinafter, warehousing and retrieval means warehousing and warehousing.

The pallets 2 located two each on the 2F, 3F, and 4F have wheels 6b at both lengthwise ends of a rectangular frame 7 for hoisting the pallets 2. The rectangular frame 7 surrounds the pallet 2 parked at an intermediate stage between the uppermost stage and the lowermost stage, and is installed so as to be able to suspend the pallet 2 and move laterally.
With this configuration, the pallets 2 located two each on the 2F, 3F, and 4F are moved horizontally by a horizontal drive device (not shown) along the horizontal rails 8b provided on each of the 2F, 3F, and 4F, and the pallets 2 are placed in the installation space A. , B, and C, the vehicle 1 is directly entered and exited from the warehouse. At 2F, 3F, and 4F, intermediate cross beams 9c extending in the width direction of the pallet 2 are supported by columns 9b of the main body frame 9. The horizontal rail 8b is supported by this intermediate stage cross beam 9c.

In this example, the two-stage parking device 100 has a pallet 2 that can be lifted and lowered with the vehicle 1 placed between the parking height (FL) at which the vehicle 1 enters and leaves the garage and a parking space above this parking space. has.
The pallets 2 that can be raised and lowered include a total of six pallets 2 located on the 2nd to 4th floors and three pallets 2 located on the 5th floor.

In this example, the two-stage parking device 100 is further equipped with an elevating drive device 5 for elevating the pallet 2.
The elevating drive device 5 winds up or unwinds a vertically extending flexible string member 4 (chain or wire) at a position that does not interfere with the vehicle 1, and raises and lowers its lower end.

The elevating drive device 5 for 2F to 4F is fixed to a rectangular frame 7 and runs horizontally together with the rectangular frame 7.
The lift drive device 5 for the 5th floor is fixed to the main body frame 9, and is configured to independently raise and lower the three pallets 2 from the main body frame 9.

In addition, in this example, the lower ends of the four string members 4 are fixed at a total of four locations on the front and rear of the pallet 2 in consideration of load balance, and the pallet 2 is raised and lowered by the lifting drive device 5 while being held horizontally. It looks like this.

Note that the present invention is not limited to the above-mentioned two-multistage parking device 100, and may be applied to other two-multistage parking devices as long as it has a plurality of pallets 2.

FIG. 2 is a plan view of a two-stage parking device 100 with a charging function according to the present invention.
The two-stage parking device 100 of this embodiment includes a charging stand 10 having a charging outlet for supplying power to the EV vehicle 1 at the rear end of the pallet 2. By connecting the charging outlet of the charging station 10 and the EV vehicle 1 with the charging cable 13, the EV vehicle 1 can be charged while the vehicle is parked. Note that, of course, a gasoline-powered vehicle can be mounted on the charging pallet of the two-stage parking device 100 of this embodiment.
Further, the two-stage parking device 100 of the present embodiment includes a top-stage cross beam 9a extending in the width direction above the rear end of the pallet 2 at the top stage (5F). The uppermost cross beam 9a is supported by supports 9b of the main body frame 9.

FIG. 3 is a view taken along the line AA in FIG. 2. Further, FIG. 4 is a view taken along the line AA in FIG. 2 when loading and unloading the pallet 2 on the 4th floor.
Above the rear end of the pallet 2, there is a beam extending in the width direction of the pallet 2. Hereinafter, this beam will be referred to as the rear beam 3.

The rear beam 3 is always present on the middle and top pallets 2.
For example, in the case of the uppermost stage, the uppermost cross beam 9a corresponds to the rear beam 3.
In the case of the intermediate stage (2F, 3F, 4F), among the four beams forming the rectangular frame 7, the beam extending in the width direction at the rear of the pallet 2 corresponds to the rear beam 3. In other words, the rectangular frame 7 includes (1) a beam extending in the width direction of the pallet 2 in front of the pallet 2, (2) a beam extending in the width direction of the pallet 2 in the rear of the pallet 2, and (3) a beam extending in the width direction of the pallet 2 on the left and right sides of the pallet 2. It has at least four beams in total, two beams extending in the longitudinal direction of the pallet 2. Of these, the beam of the rectangular frame 7 extending in the width direction of the pallet 2 at the rear of the pallet 2 corresponds to the rear beam 3 of the present invention.

Electric power supplied to each charging station 10 of the two-stage parking device 100 of this embodiment is supplied from the EV control panel 15 through the power cable 11. The two-stage parking device 100 of this embodiment includes a power cable 11 for supplying power to the charging station 10. The power cable 11 has a wiring part 14b extending from the EV control panel 15 to the rear beam 3, and a hanging part 14a that hangs down from the rear beam 3 and has a stand-side end 11b connected to the charging stand 11. That is, both ends of the power cable 11 are connected to the EV control panel 15 and the charging stand 10, and the middle part is connected to the rear beam 3. With the portion connected to the rear beam 3 as a boundary, the side closer to the charging stand is a hanging portion 14a, and the side closer to the EV control panel is a wiring portion 14b.

The wiring portion 14b of the power cable 11 is installed along the support 9b of the main body frame 9, the uppermost cross beam 9a, and the middle cross beam 9c.
For example, the wiring section 14b that supplies power to the intermediate pallet 2 is wired from the EV control panel 15 to the support 9b between two adjacent installation spaces (A, B or B, C) within the movement range of the pallet 2. From there, it passes behind the pallet 2 and is fixed to the rear beam 3 of the rectangular frame 7. The pallet 2 in the middle stage of this figure moves back and forth between two adjacent installation spaces (A, B or B, C) together with the rectangular frame 7 while being suspended from the rectangular frame 7.

With this configuration, the wiring portion 14b connecting the support 9b and the rectangular frame 7 does not protrude from the installation spaces A, B, and C in which the pallets 2 are located even if the pallets 2 in the middle stage move sideways. Therefore, there is no risk that the wiring portion 14b of the intermediate pallet 2, which has moved sideways and retreated when the upper pallet 2 is being raised or lowered, will come into contact with the pallet 2 that is being raised or lowered, the power cable 11, or the vehicle 1.
Furthermore, since the support 9b and the rectangular frame 7 are connected through the back of the pallet 2, there is no possibility of collision with the power cable 11 of the same pallet 2.

The upper end portion 11a of the hanging portion 14a of the power cable 11 is fixed to the rear beam 3 of the rectangular frame 7 in the middle stage (2F, 3F, 4F). As a result, when the pallet 2 is traveling horizontally, the upper end portion 11a of the hanging portion 14a can be horizontally traveling together with the rectangular frame 7, as shown in 2F and 3F in FIG. As a result, the power cable 11 does not hang down outside the outer edge of the pallet 2 or hang laterally beyond the outer edge of the pallet 2, so that the range occupied by the power cable 11 when viewed in plan is It can be kept inside. Therefore, since the power cable 11 does not protrude from the pallet 2, it is possible to prevent the power cable 11 from colliding with the adjacent pallet 2 or the vehicle 1.

In the two-stage parking device disclosed in Patent Document 1, a power cable that supplies power to a traversing pallet is connected to the upper end of a charging stand that stands on the pallet and to a wiring duct located outside the outer edge of the pallet. This power cable has a structure in which both ends are suspended between the charging stand and the frame body, and it extends across two adjacent installation spaces.

For example, the two-stage parking system disclosed in Patent Document 1 has three installation spaces A, B, and C, and when the topmost pallet in installation space C is to be loaded and unloaded, the two transverse pallets in the middle are moved to installation space A. and evacuate to installation space B. At this time, the power cable extending from the traversing pallet in the installation space B is suspended from the charging stand on the traversing pallet and the frame body in the installation space C with some slack. Therefore, if a charging stand-equipped pallet is placed above the intermediate pallet, the power cable and the pallet of the upper pallet will come into contact with the power cable of the intermediate pallet.
Therefore, in the two-stage parking device of Patent Document 1, it was not possible to install the charging stand-equipped pallet above the intermediate stage of the transverse pallet equipped with the charging stand.

On the other hand, in the two-multilevel parking device 100 of this embodiment, the power cable 11 is housed inside the pallet 2 in plan view, and the upper end 11a of the hanging portion 14a is fixed to the rectangular frame 7. As a result, the entire hanging portion 14a moves together with the pallet 2 to the same installation space during traverse movement. Thereby, the hanging part 14a of the power cable 11 does not protrude not only from the installation space where the pallet 2 is located but also from the outer edge of the pallet itself, so that the hanging part 14a does not enter into the installation space where the upper pallet 2 is raised and lowered.

That is, in the example of FIG. 3, for example, the hanging parts 14a from 2F to 4F have moved to the installation spaces A and B together with the rectangular frame 7 and the pallet 2, so the hanging parts 14a protrude into the installation space C. There is no.
Therefore, the pallet 2 in the installation space C on the 5th floor can be lowered to the 1st floor using the space in the installation space C without being obstructed by the power cable 11 on the 2nd to 4th floors.

Further, when the middle and top pallets 2 are lowered to the 1st floor, the hanging portions 14a extend vertically with a gentle slack as shown in FIGS. 3 and 4. As shown in the installation space C of FIG. 2, even if the power cable 11 is extended to the maximum extent, the range occupied by the hanging portion 14a is within the outer edge of the pallet 2 when viewed from above. There is no possibility that the hanging portions 14a of the pallets 2 that have descended to the 1st floor from the middle and top parking spaces will come into contact with the hanging portions 14a of the adjacent installation spaces.

Therefore, in the two-stage parking device 100 of the present embodiment, the charging stand-equipped pallet 2 can be installed above the charging stand-equipped pallet 2 that can be moved up and down.
In this way, the two-stage parking device 100 of the present embodiment fixes the upper end portion 11a of the hanging portion 14a to the beam of the rectangular frame 7 extending in the width direction behind the pallet 2, as described in Patent Document 1. The degree of freedom in design can be increased compared to a two-stage parking system.

The hanging portion 14a of the power cable 11 hangs down from the rear beam 3 at a position between both ends 2a in the width direction of the pallet 2 in the width direction of the pallet 2. In other words, the position on the rear beam where the hanging portion 14a hangs (that is, the hanging position on the rear beam in the width direction of the pallet 2) is between both ends 2a of the pallet 2 in the width direction.
For example, in the example shown in this figure, a mooring member 16 is fixed between both widthwise ends 2a of the pallet 2 in the widthwise direction of the rear beam 3. The mooring member 16 in this example is a flat metal plate with a hole, which is horizontally fixed to the rear beam 3. For example, the power cable 11 may be passed through the hole in the mooring member 16, and the power cable 11 may be fixed to the mooring member 16 at the upper end 11a of the hanging portion 14a with a fastener such as a connecting band. Note that, of course, the configuration and material of the mooring member 16 and the method of fixing the power cable 11 to the rear beam 3 are not limited to those described above.

With this configuration, when the pallet 2 is raised to each parking space, the loose power cables 11 are piled up on the pallet, so that the power cables 11 can be prevented from falling off the pallet 2. Therefore, in the two-stage parking device 100 of this embodiment, there is no need to secure a space occupied by the power cable 11 protruding from the pallet 2 outside the outer edge of the pallet 2, so there is no need to secure extra space. Therefore, the space required to park one vehicle can be smaller than the conventional two-stage parking system.
In other words, the two-stage parking device 100 has parking spaces for vehicles in five stages (1F, 2F, 3F, 4F, 5F) provided in the same installation space, but the power cable 11 is not installed. This eliminates the need to expand the installation space in the width direction. Therefore, the two-stage parking system 100 of this embodiment can be installed in the same installation area as the two-stage parking system intended for gasoline-powered vehicles only.

More specifically, the hanging portion 14a of the power cable 11 is provided on the rear beam above the center of the pallet 2 in the width direction, or above the center of the width of the pallet at a position away from the charging stand 10. It is preferable that
Thereby, when the pallets 2 in the uppermost stage and the middle stage are lowered to the 1st floor, the hanging portions 14a can be hung with some slack.

Further, the length of the hanging portion 14a includes the extra length of the cable that allows the pallet 2 to move up and down.
The stand side end 11b of the power cable 11 is connected to the charging stand 10, and the hanging part 14a is made to have slack (excess length), so that the power cable 11 does not touch surrounding equipment when the pallet 2 is raised or lowered. It can prevent you from getting caught.

FIG. 5 is an explanatory diagram of the cable protection cover 12. FIG. 5(A) is a perspective view, and FIG. 5(B) is a front view.
The two-stage parking device 100 of this embodiment includes a cable protection cover 12 that restricts bending of the hanging portion 14a of the power cable 11 in the longitudinal direction of the pallet 2. Preferably, the upper end of the cable protection cover 12 is connected to the mooring member 16.

For example, the cable protection cover 12 has a series of hollow cylindrical sheath members 17 such as a hollow cylindrical shape or a hollow rectangular parallelepiped shape, and the plurality of sheath members 17 are connected by a rotating shaft 18 extending in the horizontal longitudinal direction of the pallet 2. It has a structure. This figure illustrates a case where the sheath member 17 of the cable protection cover 12 has a hollow cylindrical shape. By passing the power cable 11 through the hollow 17a of the sheath member 17, the bending of the power cable 11 can be restricted to a vertical plane extending in the width direction of the pallet 2. As a result, the power cable 11 with the cable protection cover 12 attached cannot swing in the longitudinal direction of the pallet 2. Therefore, as shown in FIGS. 2 to 4, when the pallet 2 is raised, the power cable 11 with the cable protection cover 12 loops around an imaginary axis horizontal to the longitudinal direction of the pallet 2 and increases in height. pile up in the direction.

Thereby, even if the power cable 11 is swayed by the wind, it does not swing in the longitudinal direction of the pallet 2, so that the power cable 11 can be prevented from coming into contact with the vehicle 1 or surrounding equipment.
Moreover, since the cable protection cover 12 allows the power cables 11 to be stacked in the height direction without being coiled, the stacked power cables 11 do not spread out in the longitudinal direction of the pallet 2. This can prevent the power cable 11 from taking up space on the pallet. Further, it is possible to prevent the stacked power cables 11 from coming into contact with the vehicle 1.

According to the embodiment of the present invention described above, the power cable 11 hangs down from the rear beam 3, and the stand side end 11b beyond that has the hanging part 14a connected to the charging stand 10, and the hanging part 14a has a width It hangs down from the rear beam 3 at a position between both ends 2a in the width direction of the pallet 2 in the direction. As a result, the hanging portion 14a of the power cable 11 does not protrude outside the outer edge of the pallet 2, no matter where the pallet 2 is located in the vertical direction. That is, in the two-stage parking device 100 of this embodiment, there is no need to secure an extra space outside the pallet 2 when viewed from above to accommodate the hanging portion 14a of the power cable.
Therefore, since a space for installing the hanging portion 14a of the power cable 11 is not required on the outside of the pallet 2, the two-stage parking device 100 of the present embodiment can accommodate one vehicle more easily than the conventional two-stage parking device. The space required to park the vehicle can be reduced. In other words, the two-multistage parking device 100 of this embodiment can be installed in the same installation area as the two-multistage parking device without the charging function for the EV vehicle 1.

Note that the present invention is not limited to the embodiments described above, and it goes without saying that various changes can be made without departing from the gist of the present invention.
For example, in the example described above, one power cable 11 connects the EV control panel 15 to the charging stand 10, but the embodiments of the present invention are not limited to this. The power cable that constitutes the hanging portion 14a and the power cable that constitutes the wiring portion 14b may be prepared separately, and these power cables may be connected by the rear beam 3.
