Description

[Technical Field]

[0001] The present invention relates to a mechanical parking device, and is particularly characterized by a power supply unit that supplies power to a charging tray. [Background technology]

[0002] In recent years, electric vehicles have begun to become popular. There are various types of electric vehicles, including battery electric vehicles (BEVs) that run purely on a battery and motor, and plug-in hybrid vehicles (PHEVs) that use a combination of an internal combustion engine, a battery, and a motor, and whose batteries can be charged from an external charging station, requiring external charging of the batteries.

[0003] Some vehicle models allow for quick charging in addition to standard charging, but in either case, it takes a long time to charge the battery, so there is a growing demand for mechanical parking systems that are equipped with facilities that allow charging while the vehicle is parked.

[0004] There are several types of mechanical parking devices, including those in which vehicles are placed on trays and transported to a storage room, where the transported trays circulate within the storage room; those that are stored on storage shelves and do not move; and vertical circulation types in which charging rails are installed vertically.However, some of these charging means use complex mechanisms for the means for supplying power to the trays, or have different charging and circulation positions so that the trays cannot be moved unless they are returned to the circulation position, which increases manufacturing costs and causes inconvenience in operating the mechanical parking device.

[0005] For example, Patent Document 1 describes a mechanical parking lot that includes a plurality of parking spaces and a pallet that can carry a vehicle and is movable between the parking spaces in a first direction and a second direction that intersects with the first direction, wherein at least one of the plurality of parking spaces is provided with a power supply terminal and the pallet is provided with a power receiving terminal, the power supply terminal and the power receiving terminal are connectable in the first direction, the power supply terminal is positioned so as not to come into contact with the power receiving terminal when the pallet moves in the second direction to the parking space where the power supply terminal is provided, and after the pallet moves to a stopping position within the parking space where the power supply terminal is provided, the pallet is further moved to a charging position on the power supply terminal side, and the power receiving terminal is brought into contact with the power supply terminal.

[0006] Furthermore, Patent Document 2 discloses a mechanical parking device that includes at least one charging pallet capable of carrying an electric vehicle, and that, when storing the charging pallet in a predetermined parking shelf, moves the charging pallet in a first direction to a predetermined parking position in the parking shelf, the mechanical parking device including: a plurality of first contacts that are provided in the parking shelf and connected to a power supply device; a plurality of second contacts that are provided at the end of the charging pallet in the first direction and in positions that can face the plurality of first contacts when the charging pallet is in the parking position, and that correspond to the plurality of first contacts; and a plurality of second contacts that are provided at the end of the charging pallet in the first direction and in positions that can face the plurality of first contacts when the charging pallet is in the parking position, the plurality of first contacts being connected to a power supply device; A mechanical parking device is described, comprising: a first moving mechanism that can displace the positions of multiple second contacts in the first direction relative to the charging pallet; a second moving mechanism that is separated from the first moving mechanism and can displace the positions of the multiple first contacts in a second direction that is approximately perpendicular to the first direction relative to the parking shelf or the positions of the multiple second contacts in the second direction relative to the charging pallet; and a guide mechanism that guides the relative movement of the multiple first contacts and the multiple second contacts in the second direction so that the multiple first contacts and the multiple second contacts face each other as the charging pallet moves in the first direction.

[0007] [Patent Document 1] Patent No. 6618261 [Patent Document 2] Patent No. 6212607 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in the mechanical parking lot described in Patent Document 1, the pallet must be moved from its circulating stop position to its charging position in the power supply parking space in order to connect the power receiving terminal on the pallet to the power supply terminal on the power supply unit in the power supply parking space. In other words, when a call operation is performed to enter or exit the parking space and the pallet is circulated, the pallet must be returned from its charging position in the power supply parking space to a stopping position where it can be circulated, which interrupts charging each time. Furthermore, the exposed current collectors and other components pose a risk of electric shock to workers during maintenance.

[0009] Furthermore, the mechanical parking device described in Patent Document 2 requires that the charging pallet be moved toward a shelf-side contact assembly, which includes a first moving mechanism, a second moving mechanism, etc., and that the pallet-side contact assembly be pressed against and brought into contact with the shelf-side contact assembly in order to charge. Furthermore, the shelf-side contact assembly has a complex structure that includes multiple moving mechanisms, and installing it on each of the multiple shelves increases manufacturing costs. Furthermore, the current collectors and other components are exposed, which poses a risk of electric shock to workers during maintenance.

[0010] The present invention aims to provide a mechanical parking device that allows charging while the tray is positioned in the stopped position when the mechanical parking device is in operation, thereby preventing electric shock accidents to workers during maintenance. [Means for solving the problem]

[0012] The mechanical parking device of the second aspect is a mechanical parking device of the first aspect, wherein the oscillating body is a triangular member that is narrow at the top and wide at the bottom when viewed from the side, the top is supported by an oscillating shaft, the first parallel link mechanism is connected to the bottom side closer to the prime mover, and the support member is provided on the bottom side closer to the power supply body.

[0013] The mechanical parking device of the third aspect is a mechanical parking device of the first or second aspect, in which the cover body, the oscillating body, and the power supply oscillating member attached to the oscillating shaft together with the oscillating body are insulated from the power supply body.

[0014] The mechanical parking device of the fourth aspect is a mechanical parking device of the first aspect, in which the vertical and horizontal feed device has horizontally rotating drive wheels that contact and drive the vertical feed rails or horizontal feed rails installed on the underside of the tray from below. [Effects of the Invention]

[0015] According to the mechanical parking device of the first aspect, the cover that covers the power supply body of the power supply unit can prevent electric shock accidents for workers performing maintenance, etc., and the cover can be driven by a power-saving motor.

[0016] According to the mechanical parking device of the second aspect, simply by swinging the swinging body, the support member can bring the power supply into contact with the power receiving part of the tray in conjunction with the opening movement of the cover.

[0017] According to the mechanical parking device of the third aspect, even if a worker performing maintenance or the like accidentally comes into contact with the cover, he or she will not receive an electric shock.

[0018] According to the mechanical parking device of the fourth aspect, the tray can be moved to the adjacent storage compartment immediately after the cover has been moved to close. [Brief explanation of the drawings]

[0020] An example of a vehicle guidance device for a mechanical parking device according to this embodiment will be described with reference to the drawings. In the storage section, the long side direction of the tray in a plan view is referred to as the "longitudinal direction," the single side direction of the tray is referred to as the "short side direction," the position where the power supply unit is located is referred to as the "right side," and the opposite direction is referred to as the "left side." Furthermore, while vehicle 40 includes electric vehicles, in this invention, electric vehicles include not only pure electric vehicles (BEVs) that run solely on a battery and a motor, but also plug-in hybrid vehicles (PHEVs) that run on a combination of an internal combustion engine, a battery, and a motor. The battery referred to here is a drive battery that provides driving power for vehicle M to a motor, but also includes an auxiliary battery installed in vehicle M.

[0021] <Embodiment> [Mechanical parking system] The overall configuration of a mechanical parking device 1 in this embodiment is shown in Figures 1 and 2. The mechanical parking device 1 has an entry / exit room 2 where vehicles M, including electric vehicles, enter and exit, and a storage room 3 where vehicles M are stored. In this embodiment, the storage room 3 is located below the entry / exit room 2 and is connected to it by a lifting device 4 that raises and lowers a tray.

[0022] [Storage Room] As shown in Figure 1, the storage room 3 has multiple storage compartments 5 arranged vertically and horizontally. The storage compartments 5 have multiple empty compartments where trays are not stored, allowing for horizontal circulation of the trays. A lifting device 4 that connects to the loading / unloading room 2 is located adjacent to one of the storage compartments 5. A control panel 60 that controls the operation of the mechanical parking device 1 is installed next to the lifting device 4.

[0023] (storage compartment) As shown in Figures 3 and 4, the storage compartment 5 is a compartment that stores one tray 50 at a time, and the trays 50 are connected adjacent to each other so that they can move vertically and horizontally (see also Figure 1). The storage compartment 5 is made up of a pair of vertical feed rails 6 and a pair of horizontal feed rails 7 assembled in a rectangular shape in a plan view.

[0024] A vertical / horizontal feed device 8 is installed in the storage compartment 5 in the center of the shorter side, along the longitudinal direction of the storage compartment 5. The vertical / horizontal feed device 8 has a pair of drive wheels 9 that are rotatable vertically and horizontally and spaced apart in the longitudinal direction of the storage compartment 5. The portion between the pair of drive wheels 9 includes a vertical / horizontal switching motor 13 that switches the rotation direction of the pair of drive wheels 9 between vertical and horizontal, a vertical / horizontal switching member 14 that is mounted on the vertical / horizontal switching motor 13 so as to be rotatable horizontally, and a pair of connecting members 16 that connect each free end of the rotation of the vertical / horizontal switching member 14 to the free end of the member on which the pair of drive wheels 9 are mounted. The pair of drive wheels 9 are configured so that the rotation direction can be switched between the vertical feed direction and the horizontal feed direction by rotating the vertical / horizontal switching member 14 when driven by the vertical / horizontal switching motor 13, and by pushing and pulling the connecting member 16 to rotate the member on which the pair of drive wheels 9 are mounted.

[0025] The drive wheels 9 rotate while pressing against vertical and horizontal rails (not shown) provided on the underside of the tray 50, thereby moving the tray 50 in the vertical direction, which is the length direction of the tray 50, or in the horizontal direction, which is the short direction of the tray 50.

[0026] <Main components> [Overall configuration of main parts] Here, the configuration of the main parts will be described with reference to the drawings.

[0027] [Moving structure of power supply unit] 3 and 4, power supply unit 20 is installed inside a corner at one end of storage compartment 5. Cover 21 covers power supply unit 40, which will be described later, and prevents workers performing maintenance work and the like from accidentally receiving an electric shock. As shown in FIG. 5, the power supply unit 20 includes a swinging member 34 connected to a crank mechanism attached to the motor 26 and swinging in the direction of movement of the cover 21, a first parallel link mechanism connected to the swinging end of the swinging member 34, a second parallel link mechanism connected to the first parallel link mechanism and moving the cover 21 between a position covering the power supply 40 and a position opening the power supply 40, and a boosting member 34A fixed to the swinging end of the swinging member 34 and swinging the swinging member 34 by the crank mechanism to move the power supply 40 between a supply position where power is supplied to the receiving electrons 52 on the tray 50 and a non-supply position. When the crank mechanism is actuated to operate the first and second parallel link mechanisms and move the cover 21 to a position where the power supply 40 is opened, the boosting member 34A of the swinging member 34 can take a position where the feeding electrons 42 come into contact with the receiving electrons 52 on the tray 50. Here, the "boosting member" is an example of a support member.

[0028] 5 to 7, the cover 21 is connected, via a first parallel link mechanism and a second parallel link mechanism, to a swinging member 34 that is connected to a crank mechanism (described later) attached to a motor 26 that is installed via a bracket on the side of the cross-feed rail 7. Specifically, the crank mechanism is configured to include a second linking member 26A that is assembled to a drive shaft 26B of the motor 26, and a first linking member 25 that is rotatably attached by a shaft 25B to the free rotation end side of the second linking member 26A.

[0029] Cover 21 can be positioned to cover power supply unit 40 having electron feeder 42 (described later), which can be positioned to not supply power to tray 50, or to open power supply unit 40 having electron feeder 42 (described later), to a supply position where power is supplied to tray 50. Specifically, cover 21 is movable between the position where it covers power supply unit 20 and the position where it opens power supply unit 40 having electron feeder 42 (described later), and is operatively connected to two parallel link mechanisms including a swinging body (described later) connected to cover 21. Movement of cover 21 moves power supply unit 40 of power supply unit 20 between the power supply position and the non-power supply position. FIG. 5 shows a state in which cover 21 covers power supply unit 40, FIG. 6 shows a state in which cover 21 begins to open in the direction of arrow A' due to rotation of second link member 26A of motor 26 in the direction of arrow A, and FIG. 7 shows a state in which cover 21 is fully opened in the direction of arrow A' when rotation of second link member 26A of motor 26 in the direction of arrow A is completed. 7, the power supply element 40 having the electron supply 42 is open and exposed. The specific configuration will be described later.

[0030] [Power supply unit] FIG. 9 shows a plan view of the power supply unit 20 from above, and FIG. 10 shows a front view. The power supply unit 20 is mounted on a mounting member 30 fixed to the longitudinal feed rail 6 and the beam 17, and includes a motor 26 and a crank mechanism. A pair of first support members 31, a pair of second support members 32, and a pair of third support members 33 are fixed to the mounting member 30, spaced apart along the longitudinal feed rail 6. The first support member 31 and the third support member 33 support a swing member 34, a first link member 35, and a second link member 36 that constitute a first parallel link mechanism. The second support member 32 and the third support member 33 support a third link member 37 and a fourth link member 38 that constitute a second parallel link mechanism. The fourth link member 38 overlaps with the third link member 37. Here, the "swinging member" is an example of a swinging body.

[0031] Furthermore, a power supply rocking member 41 is supported by the base shaft 31A together with the rocking member 34 so as to be rockable, and a power supply 40 having a plurality of power supply sources 42 is provided on the free end side of the power supply rocking member 41. As shown in Fig. 10, the power supply sources 42 come into contact with a plurality of power receivers 52 provided on the power receiver section 51 of the tray 50. Here, the "base shaft" is an example of a rocking shaft.

[0032] (First parallel link mechanism and second parallel link mechanism) Here, the first parallel link mechanism and the second parallel link mechanism will be described with reference to FIG.

[0033] As shown in FIG. 11 , the first parallel link mechanism is composed of a swinging member 34, a first link member 35, and a second link member 36. The swinging member 34 is shaped like a triangular sector widening downward, and its upper portion is swingably supported on a base shaft 31A at the upper portion of the first support member 31. One end of the first link member 35 is rotatably connected to a first shaft 24B that protrudes from both ends of a shaft 24A that rotatably supports the articulating base 24 and is concentric with the shaft 24A. The other end is rotatably connected to the lower end of the second link member 36 via a second shaft 35A. The upper end of the second link member 36 is rotatably connected to a third shaft 33B that is fixed to the upper end of the third support member 33. The base axis 31A and the third axis are set at the same height from the installation member 30, and the first axis 24B and the second axis 35A are set at the same height from the mounting member 30. The axes of the base axis 31A, the first axis 24B, the second axis 35A, and the third axis 33B are each formed into a parallelogram, so that the oscillating member 34, the first link member 35, and the second link member 36 form a first parallel link mechanism.

[0034] 11, the second parallel link mechanism is composed of a third link member 37 and a fourth link member 38. The third link member 37 has a longitudinal intermediate portion rotatably supported by a fifth shaft 32A fixed to the upper end portion of the second support member 32, and an upper end portion rotatably connected to a sixth shaft 22 fixed to the cover 21. Meanwhile, the lower end portion extends below the fifth shaft 32A and is connected via a slide groove 37A to a fourth shaft 36A, which is a protruding member protruding from the lower end side of the second link member 36. The fourth link member 38 has a lower end rotatably supported by a seventh shaft 32B fixed to the upper end portion of the second support member 32 at a distance from the fifth shaft 32A, and an upper end portion rotatably connected to an eighth shaft 23 fixed to the cover 21. The fifth shaft 32A and the seventh shaft 32B are set at the same height from the mounting member 30, and the distance between the fifth shaft 32A and the sixth shaft 22 is the same as the distance between the seventh shaft 32B and the eighth shaft 23. As a result, the axes of the fifth shaft 32A, the sixth shaft 22, the seventh shaft 32B, and the eighth shaft 23 are formed into a parallelogram, and the third link member 37 and the fourth link member 38 form a second parallel link mechanism.

[0035] The first parallel link mechanism and the second link mechanism are operatively connected by the second link member 36 on the first parallel link mechanism side and the third link member 37 on the second parallel link mechanism side, and the second parallel link mechanism is operated by the operation of the first parallel link mechanism.

[0036] The power supply unit 20 opens and closes the cover 21 via the first parallel link mechanism and the second parallel link mechanism described above by the operation of a crank mechanism including the motor 26. In conjunction with the opening and closing of the cover 21, the power supply 42 provided on the power supply unit 40 moves between itself and the power receiving unit 52 provided on the power receiving unit 51 of the tray 50.

[0037] (covered) 11, cover 21 includes an upper plate 21A that covers power supply unit 40, two side plates 21B that extend downward from longitudinal ends of upper plate 21A and cover both side surfaces of power supply unit 40, and notched portions 21C of side plates 21B that face the first parallel link mechanism side. Cover 21 moves from a position that covers power supply unit 40 to a position that releases power supply unit 40 and allows it to rise.

[0038] (power feeder) The power supply body 40 is configured to include a power supply body oscillating member 41 that is freely oscillated via a base shaft 31A that supports the oscillating member 34 of the first parallel link mechanism, and is attached to the first support member 31 that rises upward on the upper surface of the installation member 30, and a power supply body 40 that is attached to the power supply body oscillating member 41 and has a plurality of electrons 42.

[0039] [Power receiving section] The power receiving unit 51 is provided on the underside of the tray 50 and has a power receiving unit 52 that is in contact with the power supply unit 42 to receive power. Although not shown, the power receiving unit 52 is connected by wiring to an outlet for charging the vehicle M that is provided on the tray 50.

[0040] <Function of main parts (operation of power supply part)> Here, the operation of power supply unit 20 will be specifically described with reference to FIGS.

[0041] First, when tray 50 carrying vehicle M, an electric vehicle, stops in storage compartment 5, motor 26 shown in Fig. 5 is driven to rotate in the direction of arrow A shown in Fig. 6. The positions of cover 21 and power supply unit 40 shown in Fig. 5 correspond to Figs. 11 and 12, the positions of cover 21 and power supply unit 40 shown in Fig. 6 correspond to Figs. 13 and 14, and the positions of cover 21 and power supply unit 40 shown in Fig. 7 correspond to Figs. 15 and 16.

[0042] 5, 11, and 12 show an initial state in which the cover 21 covers the power supply 40 having the electron supply 42. In the initial state, the power supply rocking member 41 is placed on the mounting member 33A provided on the third support member 33.

[0043] Next, when motor 26 begins to rotate in the direction of arrow A as shown in FIG. 6, first link member 25 is pushed in the direction of arrow A, and swing member 34 swings in the direction of arrow A via link base 24, as shown in FIGS. 13 and 14. Then, through the operation of the first parallel link mechanism and the second parallel link mechanism, third link member 37 and fourth link member 38 move cover 21 in the direction of arrow A', thereby beginning to open power supply 40. Although arrow A' in FIGS. 13 to 16 is shown as a straight line, this indicates the direction of movement of cover 21. Cover 21 actually moves upward in an arc in the direction of arrow A', and after passing the top dead center, moves downward in an arc in the direction of arrow A'. In conjunction with this movement, boost member 34A provided on swing member 34 begins to push up the underside of power supply swing member 41. When the vertical and horizontal feed member 8 further pivots in the direction of arrow A as shown in FIG. 7, the swinging member 34 further pivots in the direction of arrow A, and as shown in FIGS. 15 and 16, the first parallel link mechanism and the second parallel link mechanism pivot to the opposite side from their initial positions, causing the cover 21 to open the power supply body 40 having the power supply 42, and the push-up member 34A of the swinging member 34 pushes the power supply body swinging member 41 upward, causing the power supply 42 of the power supply body 40 to contact the power receiving member 52 of the tray 50. A biasing member (not shown), e.g., a spring, is built into the power supply body 40, biasing the power supply 42 upward, so that the power supply 42 presses into contact with the power receiving member 52. A position sensor (not shown) detects this state, and a power supply command is sent to the control panel 60. This charges the battery of the vehicle M, an electric vehicle, placed on the tray 50.

[0044] In the mechanical parking device 1, when an entry / exit operation is performed and the tray 50 is moved over the storage compartment 5, the power supply command from the control panel 60 is temporarily interrupted in the state shown in Figures 15 and 16, and the power supply is stopped. Then, the tray 50 is moved to the adjacent storage compartment 5. At this time, the electron supplying device 42 and the electron receiving device 52 are three-phase and therefore each is divided into three, but when the drive wheels 9 of the longitudinal and lateral feed device 8 shown in Figure 4 are rotated 90 degrees from the illustrated state and facing the lateral feed direction, the tray 50 is moved in the longitudinal direction of the electron supplying device 42 and the electron receiving device 52, so the electron supplying device 42 does not need to swing down. 4, when the tray 50 moves in the vertical feed direction, the drive wheels 9 of the vertical / horizontal feed device 8 face the vertical feed direction, so that the electron supply 42 swings downward and the covers 21 move in the opposite direction of arrow A' so as to cover the electron supply 42, and the electron supply 42 and the electron receiver 52 are positioned apart, thereby preventing interference with the vertical feed operation of the tray 50. Furthermore, during maintenance, etc., by positioning all covers 21 so as to cover the electron supply 42, workers performing maintenance, etc., can be prevented from accidentally receiving an electric shock.

[0045] 8, when the power supply 42 is to be retracted from the power receiver 52 of the tray 50, the motor 26 is driven in the same direction as the arrow A when pulling the cover 21, thereby rotating the second connecting member 26A in the direction of the arrow A and pulling the first connecting member 25 in the direction of the arrow C, returning the cover 21 in the direction of the arrow C'. This causes the power supply 40 and the power supply 42 to descend in the direction of the arrow B' and return to their original positions. In other words, when the cover 21 is moved, the motor 26 is always driven in the direction of the arrow A, which simplifies the program that controls the drive of the motor 26 and also simplifies the sensors that detect this operation, contributing to cost reduction.

[0046] Thus, the mechanical parking device 1 according to the present invention is a mechanical parking device 1 having a plurality of storage compartments 5 for storing trays 50, and each storage compartment 5 is configured to include a power supply unit 20 having a power supply body 40 that can take a supply position for supplying power to a power receiving unit 51 of the tray 50 and a non-supply position for not supplying power, and a cover 21 that can take a position for covering at least a power supply 42 of the power supply unit 20 and a position for opening it, and the power supply unit 20 includes a swinging member 34 connected to a crank mechanism attached to a motor 26 and swinging along the moving direction of the cover 21, a first parallel link mechanism connected to the swing end side of the swinging member 34, and a first parallel link mechanism. The power supply unit 20 further includes a second parallel link mechanism connected to the parallel link mechanism for moving the cover 21 between a position covering the power supply 42 and an open position, and a push-up member 34A fixed to the swing end of the swing member 34 for moving the power supply 40 between a supply position for supplying power to the power receiver 52 on the tray 50 and a non-supply position when the swing member 34 is swung by a crank mechanism. When the crank mechanism is actuated to operate the first parallel link mechanism and the second parallel link mechanism to move the cover 21 to a position for releasing the power supply 42, the push-up member 34A of the swing member 34 can take a position for bringing the power supply 42 into contact with the power receiver 42 on the tray 50.

[0047] As a result, the cover 21 covering the power feeder 40 of the power feed unit 20 can prevent electric shock accidents to workers performing maintenance, etc., and the cover 21 can be driven by the power-saving motor 26.

[0048] In addition, the oscillating body 34 is a triangular member that is narrow at the top and wide at the bottom when viewed from the side, and the top is supported by the base shaft 31A, a first parallel link mechanism is connected to the bottom side closer to the motor 26, and a push-up member 34A is provided on the bottom side closer to the power supply body 40.

[0049] As a result, simply by swinging the swinging member 34, the push-up member 34A can bring the electron supply 42 into contact with the electron receiver 52 on the tray 50 in conjunction with the opening movement of the cover 21.

[0050] Further, the cover 21, the swinging member 34, and the power supply swinging member 41 attached to the base shaft 31A together with the swinging member 34 are insulated from the power supply 20.

[0051] This prevents a worker performing maintenance or the like from receiving an electric shock even if he or she accidentally touches the cover.

[0052] The vertical and horizontal feed device 8 also has horizontally rotating drive wheels 9 that contact and drive the vertical feed rails 6 or the horizontal feed rails 7 installed on the underside of the tray 50 from below.

[0053] This allows the tray 50 to be moved to the adjacent storage compartment 5 immediately after the cover 21 has been closed.

[0054] The above describes embodiments and modifications of the present invention, but the present invention is not limited to the description in the specification or drawings, and it goes without saying that other aspects, modifications, or improvements of the present invention are included in the technical scope of the claims of the present invention.

[0055] For example, although the power supply unit 20 has been described as being provided at one corner of the storage compartment 5, this is not limiting, and a power supply unit 20 may be added to the other diagonal side of the storage compartment 5.

[0056] In addition, the number of storage compartments 5 having power supply units 20 may be set to an appropriate number depending on the number of cars that can be accommodated by the mechanical parking device 1, and may be half or one-third of the total number of cars that can be accommodated.
