Description

  The present invention relates to a mechanical parking apparatus having a charging function for an electric vehicle, and more particularly, to a mechanical parking apparatus having a charging function of a trolley power feeding method.

  2. Description of the Related Art Conventionally, mechanical parking devices for parking a plurality of vehicles have been installed in apartments, business districts, shopping districts, and the like, and effective use of space has been achieved. As this mechanical parking device, there are various types of parking devices such as a box-type circulation type, a horizontal circulation type, a plane reciprocation type, a vertical / horizontal movement puzzle type, an elevator type, a vertical circulation type, a multistage type, and a plane parking movement type. It is adopted according to installation conditions.

  On the other hand, in recent years, electric vehicles ("Electric vehicles" in this specification and claims) require charging of "Electric vehicles", "Hybrid vehicles combining electric motors and internal combustion engines", etc. Vehicle)). Such an electric vehicle is excellent in environmental conservation because it can reduce the amount of exhaust gas, but it is necessary to charge electricity to a storage battery (battery) instead of conventional fuel. Therefore, a parking device with a charging function that attempts to charge using the time stored in the parking device as described above has been invented.

  For example, as a parking device that can charge an electric vehicle, a power supply trolley wire is arranged endlessly along a cage circulation endless chain of a vertical circulation parking device, and a cage that circulates by mounting an electric vehicle, There is a battery charger and a collector having an outlet connected to the storage battery side of an automobile so that power is supplied from the power supply trolley wire (see, for example, Patent Document 1).

Japanese Patent No. 2908945

  By the way, as described above, various types of mechanical parking apparatuses are employed according to installation conditions and the like. Therefore, as a power feeding means for providing a mechanical parking apparatus with a charging function, a power feeding means that can be used for these various mechanical parking apparatuses is desired.

  However, the above-mentioned patent document 1 relates to a vertical circulation parking device, and is not applicable to all of the various mechanical parking devices described above.

  On the other hand, the trolley power feeding system, which is a power feeding mechanism between a charging pallet that moves by loading an electric vehicle and the parking device main body, is powered by bringing a collector into contact with the trolley wire, and the parking device A trolley wire is disposed on the main body side (frame side), and a current collecting assembly including current collecting is provided on the charging pallet side.

  However, in this configuration, a charging pallet having a current collector assembly that is bulky and complicated with a heavy load is circulated, and therefore, a passage is formed in every part through which this bulky current collector assembly passes. It is necessary to secure a large amount. This is the same in the above-mentioned various mechanical parking apparatuses, which enlarges the entire parking apparatus and increases the construction and equipment costs.

  In addition, the strength of the parking device structure must be strengthened to move the charging pallet equipped with a heavy current collector assembly. From this point as well, the entire parking device is enlarged and the construction and equipment costs are increased. Will be invited.

  Furthermore, when the trolley wire is arranged along the circulation path as in the above-mentioned Patent Document 1, since the current collector of the charging pallet is always in contact with the trolley wire, the travel contact time between the two becomes longer. Therefore, this shortens the life of the current collector, which is a wear replacement part, and increases the frequency of inspection / maintenance / replacement work of the current collector, leading to an increase in maintenance costs.

  In addition, since multiple current collectors are in contact with a common trolley wire, it is not possible to monitor the individual charging state (charging amount, charging time, etc.) for each charging pallet, and it is appropriate for each charged electric vehicle. The charge cannot be charged.

  Accordingly, an object of the present invention is to provide a mechanical parking device that can reduce the weight and size of the charging pallet and can monitor the charging state for each charging pallet.

  In order to achieve the above object, the present invention provides a mechanical parking device having a charging pallet having a charging relay function for charging an electric vehicle mounted thereon, wherein the charging pallet is along a moving direction of the charging pallet. The parking device body at the location of the charging pallet has a current collector that is disposed opposite to the trolley conductor wire of the power supply trolley assembly. An assembly is provided, and a connection mechanism is provided between the charging pallet and the parking apparatus main body for contacting or separating the current collecting assembly and the power supply trolley assembly. “Collector” in the specification and claims refers to a configuration in which power is supplied to the trolley conductor wire from the parking device body side. As a result, the power supply configuration provided in the charging pallet becomes a light and compact power supply trolley conductor wire, and the charging pallet can be reduced in weight and compact, and the power supply trolley assembly and the current collecting assembly for each charging pallet Since the battery is charged by contacting it at the place of placement, the charge can be settled individually by monitoring the state of charge individually.

  Further, the connection mechanism has a swinging mechanism for bringing the current collecting assembly into contact with or separating from the power feeding trolley assembly, and the swinging mechanism moves the charging pallet to a place where the current collecting pallet assembly is disposed. There may be provided a guide mechanism for contacting the trolley conductor wire. As a result, the configuration in which the current collector assembly on the parking device body side is connected to the feeding trolley conductor wire to be provided in the charging pallet is configured to swing the current collector assembly on the parking device body side, thereby reducing the weight and compactness of the charging pallet. Can be planned.

  Further, the charging pallet has a cam-shaped guide body whose guide surface changes in the horizontal direction along the moving direction, and the guide mechanism moves along the guide body to move the current collector to the trolley. You may have the roller which adjoins and separates with respect to a conductor wire. In this way, since the charging pallet moves in the moving direction, the roller moves along the cam-shaped guide body, so that the current collector is brought into contact with the trolley conductor wire by positioning the charging pallet at the arrangement location. Can do.

  The swing mechanism includes a swing base plate that includes the current collecting assembly and a roller at both ends and supports an intermediate portion, and the swing base plate has a place other than a place where the charging pallet is disposed. An elastic member that separates the current collector from the trolley conductor wire when positioned at a position may be provided. In this way, when the charging pallet is located at a place other than the location, the current collector is surely separated from the trolley conductor wire, and the charging pallet is moved to the location so that the guide body moves the swing base plate through the roller. The current collecting assembly at the other end is swung toward the power feeding trolley assembly by the rocking of the rocking base plate, so that the current collecting of the current collecting assembly is transferred to the trolley conductor of the power feeding trolley assembly. It is possible to reliably approach and separate from the line.

  Further, the power supply trolley assembly has a plurality of trolley conductor wires arranged along a moving direction of the charging pallet, and the current collecting assembly faces the trolley conductor wires at a place where the charging pallet is arranged. A plurality of current collectors arranged as described above may be provided. In this way, for example, two power supply poles and one ground pole can be stably brought into contact with each other.

  The plurality of trolley conductor lines may be arranged in series along a moving direction of the charging pallet, and the plurality of current collectors may be arranged in series facing the trolley conductor lines. In this way, a plurality of current collectors can be arranged in series on the parking device body side, and the charging pallet can be made lighter and more compact.

  Further, the plurality of trolley conductor lines may be arranged in parallel along the moving direction of the charging pallet, and the plurality of current collectors may be arranged in parallel facing the trolley conductor lines. Even in this case, a plurality of current collectors can be arranged in parallel on the parking device body side, and the charging pallet can be made lighter and more compact.

  The swing mechanism may include a link mechanism that swings the plurality of current collectors integrally. In this way, a plurality of current collectors can be integrally swung to be brought into contact with the trolley conductor wire at the same time, and the configuration for swinging the current collector can be simplified.

  According to the present invention, it is possible to reduce the weight of the charging pallet by reducing the power supply means provided in the charging pallet, and to provide a mechanical parking device that can monitor and charge the charging state for each charging pallet. It becomes possible.

  Further, the charging control device 75 includes a RAM, a ROM, and a CPU, and controls the charging of the battery BT of each electric vehicle EV mounted on the charging pallet 21 stored in the arrangement location 45. And a current monitoring unit 87 that monitors the current supplied to each charging pallet 21. The current monitoring unit 87 has an ammeter 88. Further, the charging power supply device 90 connected to the charging power supply 89 is provided with a switch 91 for each charging pallet 21, and the current on the downstream side of each of the switches 91 is detected by the ammeter 88 to be current. Monitoring is performed by the monitoring unit 87. The current monitoring unit 87 is a device that monitors a current value flowing on the downstream side of the switch 91. For example, it is determined whether or not the detected current value is smaller than a set current value equal to or greater than a predetermined threshold value. It comes to monitor.

  On the other hand, as described above, the pallet-side connector 28 is provided in each of the power supply relay portions 26 provided at the two diagonal positions of the charging pallet 21. The two power supply relay portions 26 are connected by the wiring 29 as described above, and the electric vehicle EV can be charged from any connector 28.

  In addition, the trolley conductor wire 30 of each charging pallet 21 and the current collector 36 connected to the switch 91 of the charging power supply device 90 are connected by three wires of two power supply poles and a ground electrode, The trolley conductor wires 30 of the charging pallet 21 are individually supplied with power via current collectors 36 connected to the respective switches 91 of the charging power supply device 90.

  In the illustrated example, the electric vehicle EV mounted on the charging pallet 21 is connected to the charging port 48 by the charging adapter 47 provided at the tip of the charging cable 46 connected to the connector 28 of the power feeding relay unit 26 of the charging pallet 21. The battery BT is charged. In this charging state, the switch 91 of the charging power supply device 90 connected to the charging pallet 21 on which the electric vehicle EV to be charged is mounted is “closed”.

  According to the mechanical parking apparatus 1 configured as described above, the charging pallet 21 is stored in the arrangement place 45 as described below, so that stable feeding can be performed by the feeding means 95 for each charging pallet 21. it can.

  As shown in FIG. 6A, in a state where the charging pallet 21 is near the stop position of the placement place 45 other than the placement place 45, the current collector 36 is still in a non-contact state with the trolley conductor wire 30. In this state and when the charging pallet 21 is moving or the like and is not stopped at the predetermined location 45, the roller 61 of the central swing base plate 51 is not guided to the cam surface 34 of the guide body 33, and the first tension spring 60 As a result, the swing base plate 51 is swung clockwise and comes into contact with the first stopper 63, and the current collecting assembly 37 is in a non-contact state separated from the power supply trolley assembly 31. The current collecting assembly 37 is in contact with the second stopper 64 by the action of the second tension spring 62. In this state, the current collecting assemblies 37 of the swing base plates 50 and 52 connected by the link 56 are also in the same state.

  When the charging pallet 21 traverses in the right direction (rightward), the guide body 33 and the power supply trolley assembly 31 also move rightward together, and the roller 61 of the swing base plate 51 moves to the cam surface 34 of the guide body 33. You will be guided in contact with.

  Thereafter, as shown in FIG. 6B, when the charging pallet 21 moves further to the right, the central swinging base plate 51 is swung counterclockwise against the first tension spring 60. Accordingly, the other swing base plates 50 and 52 connected by the link 56 are also swung counterclockwise. By the swinging of these swinging base plates 50, 51, 52, the current collecting assembly 37 provided on these swinging base plates 50, 51, 52 is brought close to the feeding trolley assembly 31.

  When the charging pallet 21 further moves to the right, the guide / cover 59 of the current collecting assembly 37 is guided so as to cover the entire power supply trolley assembly 31, and the current collecting 36 is brought into contact with the trolley conductor wire 30. As the roller 61 reaches the top of the cam surface 34 of the guide body 33, the arm 58 moves away from the second stopper 64, and the current collector 36 is pressed against the trolley conductor wire 30 by the elastic action of the second tension spring 62. Thus, close contact between the two is achieved.

  As described above, when the charging pallet 21 is stopped at the predetermined arrangement location 45 and the state shown in FIG. 6B is reached, the control device 75 determines whether the electric vehicle EV requiring charging is mounted on the stopped charging pallet 21. If the electric vehicle EV is requested to be charged, charging is started with the switch 91 of the charging power supply device 90 closed.

  FIG. 7 is a view showing a power feeding means 96 of the second embodiment different from the power feeding means 95 of the first embodiment shown in FIG. In addition, the same code | symbol is attached | subjected and demonstrated to the same structure as 1st Embodiment mentioned above.

  As shown in the drawing, the power supply means 96 of the second embodiment is configured to bring the current collectors 36 individually swinging into contact with the three trolley conductor wires 30 arranged in parallel. In the case of this embodiment, three trolley conductor wires 30 and three cam-like guide bodies 33 are provided side by side on the charging pallet 21, and these trolley conductor wires 30 are opposed to the parking device body 35 (housing) side. Thus, three current collecting assemblies 37 are provided. Each current collecting assembly 37 includes an arm 58 pivotally supported on a support block 57 erected on each swing base plate 51 so as to be horizontally swingable, and a current collector attached to the tip of the arm 58 so as to be swingable. An electron 36 and a guide / cover 59 that covers the current collector 36 from above and below are provided. Each swing base plate 51 is provided with the roller 61 and the first tension spring 60 described above. Since other configurations are the same as those of the power supply means 95 of the first embodiment described above, the same reference numerals are given to the same configurations, and descriptions thereof are omitted.

  Also with this power supply means 96, the swing base plate 51 swings in the clockwise direction by the action of the first tension spring 60 in a state where the charging pallet 21 is approaching the stop position other than the placement location 45 and the placement location 45. Thus, the current collector 36 is not in contact with the trolley conductor wire 30.

  When the charging pallet 21 traverses and the roller 61 of the swing base plate 51 is guided in contact with the cam surface 34 of the guide body 33, the center swing base plate is resisted against the first tension spring 60. 51 is swung counterclockwise to bring the current collector 36 into contact with the trolley conductor wire 30, and as the roller 61 reaches the top of the cam surface 34, the arm 58 moves away from the second stopper 64, and the second tension is pulled. The current collector 36 can be pressed against the trolley conductor wire 30 by the elastic action of the spring 62, and the two can be brought into close contact with each other.

  As described above, according to the mechanical parking device 1 described above, by providing the power supply trolley assembly 31 on the charging pallet 21, it is possible to reduce the weight and size of the charging pallet 21 and to reduce the weight and size of the pallet 21. It is possible to prevent enlargement of the entire parking device.

  Further, control is performed so that the current collector 36 and the trolley conductor wire 30 are in contact only when the charging pallet 21 is stopped at a predetermined position of the arrangement place 45 and is energized only when the electric vehicle EV requiring charging is mounted. As a result, both contact times in the energized state are shortened to the minimum necessary, so that the life of the current collector 36 that is a wear replacement part can be extended.

  Furthermore, since the charging state can be monitored for each charging pallet 21, the charging amount and the charging time for each charging pallet 21 are measured and the charging fee is settled, so that the electric vehicle EV that does not perform charging or It is possible to prevent unfairness related to charging between a general vehicle (non-electric vehicle EV) and a charged electric vehicle EV.
