Description

[Technical field]

[0001] The present invention relates to a pallet for parking vehicles powered by a charging cable and a parking lot for parking vehicles powered by a charging cable. In particular, the present invention relates to a pallet for parking vehicles including an electric vehicle charged by a charging cable and a parking lot for parking an electric vehicle powered by a charging cable. [Background technology]

[0002] A parking device or parking lot is used to park vehicles.

[0003] For example, a self-driving parking lot having a plurality of parking spaces is used to park a plurality of vehicles. For example, a parking device having a parking mechanism may be used to park a number of vehicles.

[0004] The parking mechanism moves and parks the vehicle between the entrance / exit space E and the parking space P. For example, parking mechanisms include merry-go-round type parking mechanisms, elevator type parking mechanisms, elevator-slide type parking mechanisms, level shuttle type parking mechanisms, transport-storage type parking mechanisms, two-level type parking mechanisms, and multi-level type parking mechanisms. For example, in a merry-go-round parking mechanism, a main chain is wound around a pair of upper and lower sprockets, and multiple cages are hung from the main chain at regular intervals and support pallets. When the sprockets are rotated, the multiple cages move in a circular motion. For example, in an elevator-type parking mechanism, multiple parking spaces are arranged vertically along a vertical shaft, and a cage carrying a vehicle is raised and lowered into the shaft, and the vehicle is transferred from the cage to a parking space and parked there. An electric motor winds up and lowers the cable that suspends the cage. Another electric motor moves the vehicle between the cage and the parking space. For example, in an elevator-slide type parking mechanism, parking spaces are arranged in multiple stages vertically and horizontally, and vehicles are placed on a transport cart and transported between the entrance / exit space E and the side of the parking space P, and the vehicles are transferred between the transport cart and the parking spaces. An electric motor moves the transport cart. Another electric motor moves the vehicle between the transport cart and the parking spaces. For example, in a horizontal reciprocating parking mechanism, the parking spaces are arranged horizontally, and a transport cart transports a vehicle between the entrance / exit space E and the side of the parking space P, and the vehicle is transferred between the transport cart and the parking space. An electric motor moves the transport cart. Another electric motor moves the vehicle between the transport cart and the parking space.

[0005] Meanwhile, the electrification of vehicles is accelerating. These vehicles are collectively referred to as electric vehicles. Electric vehicles include hybrid cars, plug-in hybrid cars, electric cars, electric motorcycles, and the like. Electric vehicles are classified into two types: those that are powered by AC electricity and those that are powered by DC electricity. Therefore, it is conceivable to supply power to an electric vehicle while it is parked. Some electric vehicles are of the type that use an external power source to charge the on-board battery. These electric vehicles have a power plug socket for power supply. Charging is performed by connecting the charging cable to the power plug of a quick charger or a 100 / 200V power outlet, and then connecting the power plug of the charging cable to the power plug socket of the electric vehicle.

[0006] In a parking device that employs a parking mechanism in which vehicles are placed on a pallet and handled, it is possible to electrically connect the power supply plug receptacle of the vehicle placed on the pallet with a charging cable to charge the vehicle while it is parked. In a parking device that employs a parking mechanism in which vehicles are placed on a pallet and handled, it is conceivable that a vehicle-side relay terminal can be provided on the pallet, and a charging cable can be used to electrically connect the power plug receptacle of the vehicle placed on the pallet to the vehicle-side relay terminal, thereby charging the vehicle while it is parked.

[0007] In order to power the vehicles mounted on the pallets via charging cables, the charging device supplies power from the power supply to the charging cable. At that time, it is necessary to take care that the vehicles do not physically interfere with the charging device. In order to supply power to a vehicle parked in a parking space via a charging cable, the charging device supplies power from the power supply to the charging cable. At that time, it is necessary to take care that the vehicle does not physically interfere with the charging device.

[0008] In addition, when the pallet carrying the vehicle is moved inside the parking device, care must be taken to ensure that the charging cable does not protrude from the pallet so as not to interfere with the equipment of the parking device. Furthermore, when supplying power to a vehicle parked in a parking space, care must be taken to ensure that the charging cable does not extend beyond the charging space to avoid physical interference with other vehicles.

With the configuration of the above embodiment, the protrusion prevention structure is elongated and has a groove provided along the sides of the approximately rectangular shape on the upper surface of the parking space, into which the charging cable can fall. As a result, the charging cable is prevented from protruding from the approximately rectangular shape of the parking space. Effect of the Invention

[0030] As described above, the pallet according to the present invention has the following advantages due to its configuration. An opening is provided along one side of the main pallet structure having a substantially rectangular outline when viewed from above, and a lid structure that is supported on the edge of the opening and can be fitted into the opening to close it and can be freely swung to change its position from a second position that opens the opening to a first position that closes the opening, and when the lid structure is pressed to change its position to the first position, it disengages from the engaged part, and the relay device supplies power to an outlet provided on the back surface of the lid structure, and power is supplied to a vehicle mounted on the pallet via a connected charging cable; When the lid structure is in a first position closing the opening, the outlet is stored in the opening, and when the lid structure opens the opening, power can be supplied to the vehicle via a charging cable connected to the outlet provided on the back surface. Since a biasing force is applied to the lid structure so as to change its position from the first position to the second position, the lid structure can easily open the opening. Since a biasing force is applied to the lid structure so as to change its position from the first position to the second position, the lid structure can easily close the opening. When in the first position, the first arm and the second arm cross each other's longitudinal directions at an acute angle and a rotational force applying device applies a rotational force to the second arm, and when in the second position, the first arm and the second arm are arranged in series with each other's longitudinal directions, so that a biasing force can be applied so as to change the position of the lid structure from the first position to the second position with a simple structure. When the attitude of the lid structure is the second attitude, the first arm and the second arm are arranged in series in the longitudinal direction, and the second axis is deviated from the imaginary line connecting the first axis and the intermediate axis. When the lid structure is in the second position, pressing the surface of the lid structure generates a torque that counteracts the rotational force acting on the second arm, causing the first arm and the second arm to cross each other. The anti-extension structure provided on the upper surface of the pallet main structure is designed to prevent the charging cable from protruding out from the long and short sides of the approximately rectangular shape, thereby preventing the charging cable from protruding out from the approximately rectangular shape of the pallet. A long shape with an uneven cross section is provided on the upper surface of the pallet main structure along the sides of the approximately rectangular shape to prevent the charging cable from protruding, thereby preventing the charging cable from protruding from the approximately rectangular shape of the pallet. A long shape with a groove is provided on the upper surface of the pallet main structure along the sides of the approximately rectangular shape so that the charging cable can drop in, thereby preventing the charging cable from protruding from the approximately rectangular shape of the pallet.

[0031] As described above, the parking lot according to the present invention has the following advantages due to its configuration. An opening is provided along one side of a parking space which has a roughly rectangular outline when viewed from above, and a lid structure which is supported so as to be freely swingable on the edge of the opening so as to fit into the opening to close it can be changed from a second position which opens the opening to a first position which closes the opening, and when the lid structure is pressed to change its position to the first position, it disengages from the engaged part, and a relay device supplies power to an outlet provided on the back surface of the lid structure and supplies power to a vehicle parked in the parking space via a connected charging cable, so that when the lid structure is in the first position which closes the opening, the outlet is stored in the opening, and when the lid structure opens the opening, power can be supplied to the vehicle via the charging cable connected to the outlet provided on the back surface. Since a biasing force is applied to the lid structure so as to change its position from the first position to the second position, the lid structure can easily open the opening. Since a biasing force is applied to the lid structure so as to change its position from the first position to the second position, the lid structure can easily close the opening. When in the first position, the first arm and the second arm cross each other's longitudinal directions at an acute angle and a rotational force applying device applies a rotational force to the second arm, and when in the second position, the first arm and the second arm are arranged in series with each other's longitudinal directions, so that a biasing force can be applied so as to change the position of the lid structure from the first position to the second position with a simple structure. When the lid structure is in the second position, the first arm and the second arm are aligned in series with each other in the longitudinal direction, and the second axis is offset from the imaginary line connecting the first axis and the intermediate axis. Therefore, when the lid structure is in the second position, pressing the surface of the lid structure generates a torque that counteracts the rotational force acting on the second arm, causing the first arm and the second arm to intersect. An anti-extension structure provided on the upper surface of the front parking space prevents the charging cable from protruding out from the long and short sides of the approximately rectangular shape, thereby preventing the charging cable from protruding out from the approximately rectangular shape of the parking space. The elongated shape with an uneven cross section prevents the charging cable from protruding outside the approximately rectangular shape from the top surface of the parking space, thereby preventing the charging cable from protruding outside the approximately rectangular shape of the parking space. A long shape with a groove is provided on the upper surface of the parking space along the sides of the approximately rectangular shape so that the charging cable can drop in, thereby preventing the charging cable from protruding outside the approximately rectangular shape of the parking space. Therefore, it is possible to provide a pallet for a parking device and a parking lot suitable for supplying power to a vehicle when the vehicle is parked. [Brief description of the drawings]

[0056] Next, a parking lot according to a second embodiment of the present invention will be described with reference to the drawings. Fig. 2 is a conceptual diagram of a parking lot according to a second embodiment of the present invention Fig. 8 is a plan view of the parking lot according to the first embodiment of the present invention.

[0057] The parking lot according to the second embodiment of the present invention is composed of a parking space 10A, a charging device 20, and a relay device 30.

[0058] The parking space 10A has an approximately rectangular outline when viewed from above, and is sandwiched between a pair of left and right long sides M of the approximately rectangular shape, with a pair of left and right guide surfaces that guide the left and right rolling tires of the vehicle, and an opening O formed on the upper surface along one side of the approximately rectangular shape. Parking space 10A has an approximately rectangular outline when viewed from above, and is sandwiched between a pair of long sides M of the approximately rectangular shape, with a pair of left and right guide surfaces that guide the left and right rolling tires of the vehicle, and an opening O on the upper surface that is formed along one of a pair of short sides N of the approximately rectangular shape.

[0059] The parking space 10A may have a protrusion prevention structure 11 that prevents the charging cable from protruding outside the substantially rectangular shape from the top surface of the parking space.

[0060] The protrusion prevention structure 11 may be unevenness provided along the sides of the substantially rectangular upper surface of the parking space 10A to prevent the charging cable from protruding. The protrusion prevention structure 11 may be a groove provided along a side of a substantially rectangular shape on the upper surface of the parking space 10A, into which the charging cable can fall.

[0061] The charging device 20 is a device that is provided in the opening O and is capable of supplying power to the vehicle 5 via a charging cable 6. The charging device 20 is a device that is provided in the opening and can supply power via a charging cable 6 to a vehicle 5 parked in the parking space. The configuration of the charging device 20 is the same as that of the pallet according to the first embodiment, and therefore a description thereof will be omitted.

[0062] The relay device 30 is a device that is provided in a parking space and supplies power received from a power supply device to the charging device 20.

[0063] The operation of the parking lot according to the embodiment of the present invention will be described below.

[0064] Vehicle 5 drives through the parking lot and stops in parking space 10A. The driver or worker presses the surface of the lid structure 22 with his / her foot or hand until the surface of the lid structure 22 is lowered below the upper surface around the opening O, and then releases the foot or hand from the surface of the lid structure 22. The engaging device 15 disengages from the engaged portion 21, and the position of the lid structure 22 changes from the first position to the second position. A driver or an operator inserts one end of the charging cable 6 into the outlet 23 and connects the other end to a power supply plug receptacle of the vehicle. Power is supplied to the vehicle 5 via a charging cable 6 connected from the power supply device to a relay device and an outlet 23 . When leaving the parking lot, the driver or an employee removes the charging cable 6 from the outlet 23. The surface of the lid structure 22 is pressed to change the position of the lid structure 22 from the second position to the first position, and the lid structure 22 is fitted into the opening O. The vehicle drives itself out of the parking space.

[0065] As described above, the pallet 100 according to the embodiment of the present invention has the following advantages due to its configuration. An opening O is provided along one side of the pallet main structure 10, which has a substantially rectangular outline when viewed from above, and a lid structure 22, which is supported so as to be freely swingable on the edge of the opening O and can fit into and close the opening O, can be changed from a second position that opens the opening O to a first position that closes the opening O, and when the lid structure 22 is pushed to change its position to the first position, it disengages from the engaged portion 21, and the relay device 30 supplies power to an outlet 23 provided on the back surface of the lid structure 22, and supplies power to a vehicle 5 mounted on the pallet 100 via a connected charging cable 6. Therefore, when the lid structure 22 is in the first position that closes the opening O, the outlet 23 is stored in the opening O, and when the lid structure 22 opens the opening O, power can be supplied to the vehicle via the charging cable 6 connected to the outlet 23 provided on the back surface. Since a biasing force is applied to the lid structure 22 so as to change its position from the first position to the second position, the lid structure 22 can easily open the opening O. Since a biasing force is applied to the lid structure 22 so as to change its position from the first position to the second position, the lid structure 22 can easily close the opening O. When in the first position, the first arm 24a and the second arm 24b intersect with each other in their longitudinal directions at an acute angle, and a rotational force biasing device biases a rotational force to the second arm 24b. When in the second position, the first arm 24a and the second arm 24b are arranged so that their longitudinal directions are in series with each other, so that a biasing force can be applied so as to change the position of the lid structure 22 from the first position to the second position with a simple structure. When the lid structure 22 is in the second position, the first arm 24a and the second arm 24b are aligned in series with each other in the longitudinal direction, and the second axis h2 is offset from the imaginary line connecting the first axis h1 and the intermediate axis h0. Therefore, when the lid structure 22 is in the second position, pressing the surface of the lid structure 22 generates a torque that counteracts the rotational force acting on the second arm 24b, causing the first arm 24a and the second arm 24b to intersect. The protrusion prevention structure provided on the upper surface of the pallet main structure 10 prevents the charging cable 6 from protruding outside the approximately rectangular shape, so that the charging cable 6 can be prevented from protruding outside the approximately rectangular shape of the pallet 100. Since unevenness is provided on the upper surface of the pallet main structure 10 along the sides of the approximately rectangular shape to prevent the charging cable 6 from protruding, the charging cable 6 can be prevented from protruding from the approximately rectangular shape of the pallet 100. Grooves are provided on the upper surface of the pallet main structure 10 along the sides of the approximately rectangular shape so that the charging cable 6 can fall therein, thereby preventing the charging cable 6 from protruding from the approximately rectangular shape of the pallet 100.

[0066] As described above, the parking lot according to the present invention has the following advantages due to its configuration. An opening O is provided along one side of a parking space having a roughly rectangular outline when viewed from above, and a lid structure 22 is supported so as to be freely swingable on the edge of the opening O so that it can fit into the opening O to close it, and its posture can be changed from a second posture that opens the opening O to a first posture that closes the opening O, and when the lid structure 22 is pushed to change its posture to the first posture, it disengages from the engaged portion, and the relay device supplies power to an outlet provided on the back surface of the lid structure 22 and supplies power to a vehicle parked in the parking space via a connected charging cable, so that when the lid structure 22 is in the first posture that closes the opening O, the outlet is stored in the opening O, and when the lid structure 22 opens the opening O, power can be supplied to the vehicle via the charging cable connected to the outlet provided on the back surface. Since a biasing force is applied to the lid structure 22 so as to change its position from the first position to the second position, the lid structure 22 can easily open the opening O. Since a biasing force is applied to the lid structure 22 so as to change its position from the first position to the second position, the lid structure 22 can easily close the opening O. When in the first position, the first arm 24a and the second arm 24b intersect with each other in their longitudinal directions at an acute angle, and a rotational force biasing device biases a rotational force to the second arm 24b. When in the second position, the first arm 24a and the second arm 24b are arranged so that their longitudinal directions are in series with each other, so that a biasing force can be applied so as to change the position of the lid structure 22 from the first position to the second position with a simple structure. When the lid structure 22 is in the second position, the first arm 24a and the second arm 24b are arranged in series with their longitudinal directions aligned, and the second axis is offset from the imaginary line connecting the first axis and the intermediate axis. Therefore, when the lid structure 22 is in the second position, pressing the surface of the lid structure 22 generates a torque that counteracts the rotational force acting on the second arm 24b, causing the first arm 24a and the second arm 24b to intersect. The protrusion prevention structure provided on the upper surface of the front parking space prevents the charging cable 6 from protruding outside the approximately rectangular shape, so that the charging cable 6 can be prevented from protruding outside the approximately rectangular shape of the parking space 10A. The unevenness prevents the charging cable 6 from protruding outside the approximately rectangular shape from the top surface of the parking space, so that the charging cable 6 is prevented from protruding outside the approximately rectangular shape of the parking space 10A. A groove is provided on the upper surface of the parking space along the sides of the approximately rectangular shape so that the charging cable 6 can fall therein, thereby preventing the charging cable 6 from protruding from the approximately rectangular shape of the parking space 10A.

[0067] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the invention. Although the biasing device has been described as being composed of the first arm and the second arm, the biasing device is not limited to this. For example, the biasing device may be composed of a spring and a guide rod. Although the protrusion prevention structure having a pair of L-shaped longitudinal shapes on the left and right has been shown, the present invention is not limited to this. For example, the protrusion prevention structure may have L-shaped longitudinal shapes on the front, back, left and right. [Explanation of symbols]
