Description

  The present invention relates to a multi-story parking apparatus, and more particularly, to a multi-story parking apparatus using non-contact power feeding.

  As mechanical parking devices for parking vehicles (automobiles), three-dimensional parking lots such as circular circulation parking devices, box-type circulation parking devices, elevator parking devices, and plane reciprocating parking devices are widely used.

  In the lower boarding type elevator parking apparatus shown in FIG. 12, a cage 402 (not shown) for moving up and down in the hoistway 403 is provided in a lower part (for example, the ground) of the apparatus where a vehicle 401 enters and exits. A parking rack (not shown) provided in multiple stages along the hoistway 403 is provided on both sides of the hoistway 403, and the car 401 gets on the moving floor 410 on the cage by the ride-in part 402, and the cage rises to perform predetermined parking. The car 401 is stored together with the moving floor 410 in each parking shelf by the traversing device 406. At the time of delivery, a car is delivered from the same boarding part 402 by this reverse operation (Patent Documents 1, 2, etc.).

  In addition, a rotary table (not shown) is built in the cage so that the direction of the car can be reversed at the time of loading and unloading so that it can always be moved in and out (180-degree type), and the direction of the cage and parking rack Are arranged in a direction orthogonal to the traveling direction of the car, and the rotary table is rotated 90 degrees horizontally to move the car in and out (90-degree type).

  In such an elevator parking apparatus, the drive device includes a lift (not shown) for moving up and down and a traverse device 406 for performing horizontal movement. Conventionally, there is a trolley system provided with a power feeding device that supplies power to the traversing device 406 that is a moving body to feed power to these driving devices, particularly to the traversing device 406 that is a moving body. The power supply device is configured to transfer power between a power supply line routed along a rail on which the mobile body travels and an electron receiver provided on the mobile body, and the power received by the power receiver is transferred to the mobile body. It comes to supply. As a power supply device used here, a brush is used for receiving electrons, and a contact-type power supply device in which this brush is always in contact with a power supply line is widely used (see, for example, Patent Document 3).

JP 2001-359203 A (FIG. 1) Japanese Utility Model Publication No. 06-020794 (FIG. 4) Japanese Unexamined Patent Publication No. 09-255279 (page 3, FIG. 1)

However, in the contact-type power supply device, the brush moves while always in contact with the power supply line, so that the brush and the power supply line are worn, and contamination or incomplete contact due to separation is likely to occur.
Further, since the vehicle body that is contaminated by running in rain or dust is stored, poor contact may occur due to contamination.
Therefore, it is necessary to periodically replace brushes, power supply lines, and other parts, which increases the running cost.
In addition, in a multilevel parking lot that is used without holidays, maintenance is difficult, and there is a problem that a great deal of human labor is required for maintenance at high places.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a highly reliable three-dimensional parking apparatus that can reduce the frequency of maintenance.
Another object of the present invention is to provide a power feeding device having excellent power transmission characteristics.

Accordingly, the multi-story parking apparatus of the present invention includes a moving floor on which a vehicle body is placed, a driving device that moves the moving floor in a vertical direction and a horizontal direction, and a power feeding device that feeds power to the driving device. However, the moving bed is driven by supplying a power supply line through which a current flows and a pickup unit inductively coupled to the power supply line and supplying power to the driving device by an induced electromotive force induced in the pickup unit. The pickup unit has a cylindrical core surrounding the power supply line along the circumferential direction, and a coil formed by winding a winding around the core, and the core has at least the power supply line in the radial direction. Both ends of the core that are passable and that are provided along the axial direction of the feeder line, and that have at least one of an inner peripheral surface or an outer peripheral surface formed of a curved surface, and that are opposed to each other with the opening groove therebetween Part of the core Than to the region excluding the both end portions, the area of the cross section along the axial direction Ru is larger.
According to this configuration, since it is a non-contact power feeding method, power can be fed without a sliding portion, and the moving bed is driven by feeding power to the driving device by induced electromotive force induced in the pickup portion. Therefore, there is no generation of wear powder, and the maintenance frequency can be reduced in a clean environment. In addition, since at least one of the inner peripheral surface or the outer peripheral surface of the cylindrical core is configured by a curved surface, the inner peripheral surface and the outer peripheral surface of the core are both configured by abutting a plurality of planes. Thus, the magnetic flux leaking out of the core can be reduced. As a result, the efficiency of power transmission from the power supply line to the pickup unit can be improved and the power supply amount can be increased as compared with the conventional case. Furthermore, the magnetic resistance at both ends of the core can be relatively reduced, and the magnetic flux leaking from the opening groove to the outside of the core can be reduced.

Further, the present invention is the above-described multi-story parking apparatus, further comprising a charging device that charges the vehicle body placed on the moving floor, and the charging device is configured to be powered by the power feeding device. It is characterized by that.
According to this configuration, when charging is performed at the time of parking, charging can be performed extremely efficiently by non-contact power feeding. Therefore, charging of an electric vehicle or the like can be easily realized by using the parking time.

In the multi-story parking apparatus according to the present invention, the core is characterized in that both the inner peripheral surface and the outer peripheral surface are curved surfaces, and the cross-sectional shape intersecting the axial direction is substantially C-shaped.
According to the said structure, the magnetic flux which leaks out of a core can further be reduced.

In the multi-story parking apparatus according to the present invention, the coil has a single-layer winding wound around the core.
According to this configuration, the high frequency resistance of the coil can be reduced as compared with the case where the winding is wound in multiple layers.

According to the present invention, in the multi-story parking apparatus, the pickup unit includes a magnetic shield body that surrounds the outside of the core.
According to the above configuration, it is possible to reduce the loss by suppressing the influence of the external magnetic field on the core and the coil.

According to the present invention, since it is a non-contact power feeding method, power can be fed without a sliding portion, and the moving bed is driven by feeding power to the driving device by induced electromotive force induced in the pickup portion. Therefore, there is no generation of wear powder, and the maintenance frequency can be reduced in a clean environment.
Further, according to the present invention, the efficiency of power transmission from the power supply line to the pickup unit can be improved and the power supply amount can be increased.

(Embodiment 1)
1-5 is a figure which shows the multi-story parking apparatus using the non-contact-type electric power feeder of Embodiment 1 of this invention. 1 is a schematic diagram of a parking device main body of a multi-story parking device, FIG. 2 is a schematic configuration diagram showing the whole multi-story parking device, FIG. 3 is a cross-sectional view of a power supply line, and FIG. FIG. 5 is an explanatory view of magnetic flux passing through the core in the pickup.

  The three-dimensional parking apparatus according to the first embodiment includes a parking apparatus main body 400 including a moving floor 410 on which a vehicle 401 is placed, a driving apparatus that moves the moving floor 410 in the vertical direction and the horizontal direction, and a parking apparatus. The power supply device 200 includes a power supply device 200 that supplies power to a motor serving as a drive device 111 mounted on the main body 400. The power supply device 200 includes a power supply line 100 through which a high-frequency current flows and a core 2 that is inductively coupled to the power supply line 100. The moving bed 410 is configured to be driven by supplying power to the driving device by induced electromotive force induced in the pickup unit 1 provided. The power supply line 100 is fixed to a wall by a jig (not shown), and power is received while the pickup unit 1 moves along the power supply line 100.

  Furthermore, the vehicle 401 mounted on the moving floor 410 is provided with a charging device 500 that charges the vehicle 401. The charging device includes an AC outlet inverter 501 and a vehicle charging outlet 502. The battery is charged by non-contact power feeding.

  That is, the multi-story parking apparatus according to the embodiment includes a feed line 100 installed in a loop shape as shown in FIG. 2, a high-frequency power source 110 that sends a high-frequency current to the feed line 100, and a pickup unit that is inductively coupled to the feed line 100. 1 and supplies power to the moving floor 410 of the parking device main body 400 and the battery charging device 500 via a driving device 111 including a motor as a load from the pickup unit 1.

  As shown in FIG. 3A, the power supply line 100 includes a cylindrical inner tube portion 101, a cylindrical outer tube portion 102 disposed outside the inner tube portion 101, an inner tube portion 101, and an outer tube portion. The connecting part 103 that connects the two parts 102 so as to be concentric with each other is formed by coating a conductor integrally formed by bending a metal plate with an insulator 104 made of a synthetic resin molded product having a rectangular tube shape. ing. That is, in a power supply line through which a high-frequency current flows, there is a resistance (high-frequency resistance) due to the skin effect and proximity effect in addition to the electrical resistance of the conductor material (metal plate). By using it for 100, it is possible to reduce the high-frequency resistance and the loss as compared with the cylindrical conductor.

  The power supply line is not necessarily limited to this structure, and the manufacturing method is not only bending, but also metal extrusion or the inner tube portion 101 including the connecting portion 103 in the outer tube portion 102. It can also be manufactured by a method such as press-fitting. As an example, a modification is shown in FIG. This power supply line connects the cylindrical inner tube portion 101, the cylindrical outer tube portion 102 disposed outside the inner tube portion 101, and the inner tube portion 101 and the outer tube portion 102 so as to be concentric with each other. The four conductors 103 are covered with an insulator 104 made of a square tube-shaped synthetic resin molded product.

  Here, the pickup unit 1 includes a core 2, a coil 3, a bobbin 4, a magnetic shield body 5, and a power receiving circuit unit 6. The power receiving circuit unit 6 includes a capacitor that forms a resonance circuit together with the coil 3, a constant voltage circuit that makes the resonance voltage output from the resonance circuit of the coil 3 and the capacitor constant, and the like.

  Further, as shown in FIG. 4, the core 2 is formed with a curved surface (cylindrical surface) on both the inner peripheral surface and the outer peripheral surface, and has a substantially C-shaped cross section that intersects the axial direction (perpendicular to the paper surface). Has been. Here, both end portions 20 of the core 2 facing each other with the opening groove 2a interposed therebetween are cross sections along the axial direction, rather than portions (hereinafter referred to as “body portions”) 21 excluding the both end portions 20 of the core 2. The area is formed large.

  Further, the bobbin 4 is formed of a rectangular tube-shaped resin molded product curved in an arc shape, and outer casings 40 are provided at both end portions in the axial direction. The core 2 is divided into two body parts 21 at the opposite side of the opening groove 2a, and the end parts of the body part 21 are joined to each other after the bobbin 4 is extrapolated to each body part 21. Thus, the core 2 shown in FIG. 4 is configured. Here, the core 2 has a two-divided structure, but may not be divided.

  The coil 3 is formed by winding a winding having an insulating coating around the bobbin 4 in a single layer. The step between the end 20 of the core 2 and the body 21 is set larger than the diameter of the winding so that the coil 3 does not protrude beyond the end 20 of the core 2. Thus, since the coil 3 does not protrude outside the end portion 20 of the core 2, magnetic flux leaking from the end portion of the coil 3 to the outside of the end portion 20 of the core 2 can be reduced.

  The magnetic shield body 5 is formed in a substantially cylindrical shape by a metal magnetic material having a high magnetic permeability, and is extrapolated to the core 2 and the coil 3. However, the magnetic shield body 5 is provided with a groove 5a communicating with the opening groove 2a of the core 2 along the axial direction. The magnetic shield 5 is not essential and may be omitted.

  As shown in FIG. 2, the core 2 has a substantially U-shaped outer section so as to straddle the power supply line 100 from the side, and the core 2 is located on both sides of the power supply line 100 inside the outer structure. A pair of coils are arranged opposite to each other to constitute an electromagnetic pickup. Here, the coil is preferably as close as possible to the feeder line 100. Then, when a high frequency current is supplied from the power source 110 to the power supply line 100, a magnetic field MF is generated and attenuated according to the frequency of the supplied high frequency current around the power supply line 100. As the magnetic flux density changes, an induction current is generated in the coil (electromagnetic induction).

  In the power receiving circuit section 6 shown in FIG. 2, the current generated in the coil in this way is stabilized by a resonance circuit (not shown), and then the inverter of the driving device 111 provided in the traversing device from the constant voltage circuit. Send to. In the inverter 411 and the motor 412 constituting the driving device 111 for driving the moving floor 410, the inverter 411 converts the current into a direct current and supplies the direct current to the motor 412.

  In this way, when a high frequency current flows through the opening groove 2a to the power supply line 100 disposed inside the core 2, as shown in FIG. 5, a high frequency magnetic field (magnetic flux φ) is formed on a concentric circle centering on the power supply line 100. And most of the magnetic flux φ passes through the core 2 along the circumferential direction.

At this time, a comparative example is shown in FIG. When the inner peripheral surface and the outer peripheral surface of the core 2 ′ are both configured by abutting a plurality of planes as in the usual structure, that is, when the core 2 ′ has a substantially U-shaped cross section, FIG. As shown in the figure, a part of the magnetic flux φ leaks out of the core 2 ′ at the boundary portion (corner portion) between the flat surfaces, but the core 2 in the present embodiment has both the inner peripheral surface and the outer peripheral surface. Since the cross-sectional shape that is formed of a curved surface and intersects in the axial direction is substantially C-shaped, as shown in FIG. 5, almost no magnetic flux φ leaks outside from the portion other than the opening groove 2a.
For this reason, compared with the core 2 ′ of the comparative example shown in FIG. 6, the core 2 of the present embodiment has improved power transmission efficiency from the feeder 100 to the pickup unit 1 as shown in FIG. The amount of power supply can be increased.

  As shown in FIG. 1, the parking apparatus main body constitutes a lower boarding type elevator parking apparatus, and a boarding section 402 into which a vehicle 401 enters and exits is provided in the lower part (for example, the ground) of the apparatus, and the inside of the hoistway 403 , And a moving floor 410 provided in multiple stages on both sides of the hoistway 403. A car 401 gets on the cage at the riding portion 402, and the cage 404 rises to a predetermined moving floor 410. The vehicle 401 is stored on each moving floor 410 by a traversing device 406 that is installed in a cage and driven by a motor 412. At the time of delivery, the vehicle is delivered from the same boarding part 402 by this reverse operation.

  Also, a rotary table (not shown) is built in the cage 404 so that the direction of the car can be reversed at the time of loading and unloading so that the car can always be moved in and out (180-degree type). There is an arrangement (90-degree type) in which the direction of the vehicle is arranged perpendicular to the traveling direction of the car and the rotary table is rotated 90 degrees horizontally to move the car in and out.

  In such an elevator parking apparatus, the drive device includes a lift (not shown) for moving up and down and a traverse device 406 for performing horizontal movement. Power supply to these drive devices, particularly power supply to the traversing device 406, which is a moving body, is realized by this non-contact power supply.

  In the present embodiment, both the inner peripheral surface and the outer peripheral surface of the core 2 are formed of curved surfaces, but a modification is shown. For example, only the outer peripheral surface may be configured with a curved surface as shown in the cross-sectional view of the core in FIG. 7, or only the inner peripheral surface may be configured with a curved surface as shown in the cross-sectional view of the core of the modified example in FIG. Any of these shapes of the core 2 may be a portion other than the opening groove 2a as compared with the conventional core 2 'in which the inner peripheral surface and the outer peripheral surface are both configured by abutting a plurality of planes. It is possible to reduce the magnetic flux φ leaking from the outside. However, it is clear that the power transmission efficiency of the core 2 of the present embodiment is the highest with respect to these two types of cores 2.

  By the way, in the case where one of the two feed lines 100 going back and forth to the high frequency power supply 110 is arranged inside the core 2 and the other feed line 100 is arranged in the vicinity of the pickup unit 1. The magnetic flux generated around the other power supply line 100 cancels out with the magnetic flux φ passing through the core 2, and as a result, the power transmission efficiency of the pickup unit 1 may be reduced. On the other hand, in the present embodiment, since the core 2 and the coil 3 are covered with the magnetic shield body 5 and magnetically shielded, the magnetic flux φ passing through the core 2 as described above is an external magnetic field (magnetic flux). Can be prevented, and as a result, loss can be reduced.

  Further, in the present embodiment, the opening groove 2a is provided in the core 2 of the pickup unit 1 so as to be easily attached to and detached from the power supply line 100. In this opening groove 2a (gap), a magnetic circuit is provided. This greatly increases the magnetic resistance. Therefore, in the present embodiment, the both end portions 20 of the core 2 facing each other across the opening groove 2a are formed to have a larger cross-sectional area along the axial direction than the body portion 21 excluding the both end portions 20 of the core 2. The magnetic resistance at both end portions 20 of the core 2 is relatively reduced as compared with the body portion 21, and the magnetic flux leaking out of the core 2 from the opening groove 2a is reduced.

  Furthermore, when a coil is formed by winding multiple windings, the high frequency resistance of the winding may increase due to the proximity effect, which may reduce the efficiency of power transmission. Therefore, in the present embodiment, by forming the coil 3 by winding a single layer of the winding around the core 2, the high frequency resistance of the coil 3 is reduced as compared with the case where the winding is wound in multiple layers, and as a result The transmission efficiency can be improved.

As described above, according to the multi-story parking apparatus of the present invention, since it is a non-contact power feeding method, power can be fed without a sliding part, and the drive apparatus is driven by the induced electromotive force induced in the pickup part 1. Since the moving floor is driven by supplying power, no wear powder is generated, and the maintenance frequency can be reduced in a clean environment.
In addition, since charging can be performed extremely efficiently by non-contact power feeding when charging during parking, charging of an electric vehicle or the like can be easily realized using parking time.

In this non-contact power supply device, it is necessary to control the distance between the power supply line through which the current flows and the pickup unit with high accuracy, and this positioning is important. For example, in a non-contact state with respect to the feeder member, the coil member in which the feeder line is routed, the wire hanger that is attached to the routing member and fixes the feeder line to the routing member, A power receiving device connected to the moving body and supplying power obtained by electromagnetic induction by current flowing through the power supply line to the moving body, and the wiring member in a direction along a wiring path of the power supply line You may make it comprise the positioning structure which positions the said electric wire hanger to the said wiring member so that the attachment position of an electric wire hanger can be selected.
According to this configuration, the wire hanger can be positioned on the routing member so that the attachment position of the wire hanger with respect to the routing member in the direction along the routing path of the feeder line can be selected by the positioning structure. A desired position of the electric wire can be fixed to the wiring member by the electric wire hanger, and the assemblability of the non-contact type power feeding device can be improved.
