Description

  The present invention relates to a mechanical parking lot device that charges a storage battery of an electric vehicle during parking time.

  Recently, due to increasing interest in environmental issues, electric vehicles have been developed in place of conventional fossil fuel vehicles that generate exhaust gas, and this trend is expected to become even more prominent in the future. Such an electric vehicle has a clean feature that does not generate exhaust gas, but has a disadvantage that it takes a relatively long time to charge the storage battery with electric power as an energy source. Will be done during the waiting time when the car is not used or during parking at night. Moreover, in an urban area where electric vehicles are expected to be spread at an early stage, a mechanical parking lot apparatus that uses a narrow space three-dimensionally and stores vehicles efficiently is common. In view of this, a mechanical parking lot device has been proposed in which the time for parking is used to charge an automobile. That is, each tray on which an automobile is mounted is provided with a charger and a power receiving side contact, and each storage space for storing these trays is provided with a power supply side contact connected to a power source so that the tray is stored in the storage space. When this is done, the power receiving side contact and the power feeding side contact are connected to charge the automobile (see, for example, Patent Document 1).

No. 2908939 (paragraph numbers 0014 to 0020, FIG. 1)

  However, the above-described conventional device is connected at a low speed to prevent the power supply side contact and the power reception side contact from being damaged when connecting the power supply side contact on the storage space side and the power reception side contact on the tray side. There is a problem that so-called connection operation for moving the tray is required, and it takes time for the warehousing operation. In addition, even if the connection operation between the power supply side contact and the power reception side contact is performed at a low speed, it is not possible to prevent deterioration of the power supply side contact and the power reception side contact over time by repeating this operation. There was also a problem that parts replacement was required and maintenance costs were increased. Further, dust and dirt may adhere to the power supply side contact and the power reception side contact, which may cause a contact failure. Further, the connection operation of the power supply side contact and the power reception side contact has only one direction of operation because the shape of the contact is convex or concave. Therefore, charging was possible only at the end of the storage space.

  The present invention was made from the actual situation in the above-described prior art, and its purpose is a mechanical parking system that can charge a storage battery provided in an automobile on a tray without requiring connection between a power feeding side and a power receiving side. The object is to provide a parking device.

  In order to achieve the above object, the present invention comprises a plurality of trays on which automobiles are placed, and a transfer means for transferring these trays between an entrance / exit and a plurality of storage spaces.

Connect the other end of the cable connected to the car to the car. Next, the tray is stored in a storage space provided with a primary coil connected to the high-frequency electromagnetic device by the transfer means, and the primary coil and the secondary coil are set to face each other. In this state, high-frequency power is sent from the high-frequency electromagnetic device to the primary coil, the power is transmitted to the secondary coil on the principle of electromagnetic induction, and the vehicle is charged via the cable. Thereby, the storage battery provided in the automobile on the tray can be charged without requiring connection between the power feeding side and the power receiving side.

  In addition, the primary coil is provided in the specific storage space, the secondary coil and the cable are provided in the specific tray, and the calling unit is configured to call the specific tray at the loading / unloading port. It is characterized by providing.

  With this configuration, when charging a car by using the parked time, a specific tray, that is, a charging tray is called by the calling means at the time of warehousing. Connect to the car side. In this state, when the charging tray is stored in the specific storage space, that is, the charging storage space by the transfer means, the primary coil and the secondary coil face each other. In this state, high-frequency power is sent to the primary coil, the power is transmitted to the secondary coil based on the principle of electromagnetic induction, and the vehicle is charged via the cable. Thus, the utilization efficiency of a charging equipment can be improved by providing a charging equipment only in a specific tray and a specific storage space.

  According to the present invention, it is possible to charge the storage battery provided in the automobile on the tray without contact between the power feeding side and the power receiving side, that is, in the case of a non-charging tray. Equivalent tray moving speed and moving direction are possible, and the operation efficiency can be improved. Further, there is no deterioration over time of the power supply side and the power receiving side device accompanying the connection, and the durability of the device can be improved.
