Description

TECHNICAL FIELD The present invention relates to a pallet of a multilevel parking system for charging an electric vehicle during parking in a parking space of the multilevel parking system.

Multilevel parking systems are widely used in densely populated residential areas as parking facilities that can efficiently park a large number of vehicles on land with limited space. is provided. As one type of the multi-level parking system, there is a so-called pallet-type multi-level parking system in which a vehicle is mounted on a pallet and moved. In addition, the pallet-type multi-storey parking system is combined with a lifting lift and a multi-storey parking floor to further improve parking efficiency.

As an example of such a pallet-type multilevel parking system, for example, an elevator-type parking lot is configured as follows. Elevator-type parking lots have a vertical hoistway for lifts in the center of a building erected on the ground, and parking rooms are provided in layers on either side or one side of this hoistway. A pallet is mounted on the upper part of the lifting lift, and the lifting lift moves up and down with the vehicle placed on the pallet to convey the vehicle between the loading/unloading floor and the parking room. On the loading/unloading floor, the lifting lift is stopped so that the pallet and the floor surface of the loading/unloading floor are at the same height when the vehicle is loaded/unloaded. Once the lift is moved into each parking compartment, the pallet is slid on the lift and the vehicle is loaded and unloaded with the pallet.

2. Description of the Related Art In recent years, electric vehicles that have an electric motor as a drive source for running and run by driving the electric motor with electric power stored in a storage battery have become widespread. In an electric vehicle, it is necessary to charge the storage battery in order to run, but there is a problem that the time required for charging is longer than the time required for refueling a vehicle with an internal combustion engine. For this reason, there has conventionally been proposed a three-dimensional parking system configured to charge the electric vehicle while it is stored (see, for example, Patent Document 1).

Patent Document 1 discloses the following configuration. On the pallet of the multi-storey parking system, a power supply drum is installed on which the winding-side charging (power) cable with a power supply plug at the tip can be pulled out, and connected to the other end of the winding-side charging (power) cable. The fixed side power supply cable provided as a part is connected to the movable side contact portion. The floor of the storage space at the pallet stop position is equipped with a fixed side contact section connected to a power supply. When this fixed side contact section and the movable side contact section of the pallet come into contact, the pallet side is energized and power is supplied. Charging is performed by connecting the plug to the electric vehicle.
