Abstract

The present invention relates to an electric charging system for a mechanical parking facility. According to the present invention, a slow-speed charger and a fixed connector part are installed in a carport frame body, which is a frame body of each carport, and at the same time a moving connector part and a charging gun are installed on a pallet such that the connection of the connector parts is automatically determined depending on whether a pallet is carried into or out of each carport, thereby enabling an electric vehicle to be accurately charged without extra control by a manager or a driver. When the connector parts are connected, second bus bars of the fixed connector part are placed in an upper part of an internal space of a connection hole of a connection part, while first bus bars of the moving connector part are placed in a lower part of the internal space. Accordingly, the first and second bus bars come in contact with each other in a wide area, which can lead to an increase in the efficiency and safety of power supply as well as an enhancement in the connection force of the first and second bus bars. Moreover, an upper pressure body of the connection part presses the second bus bars of the fixed connector part downwards and a lower pressure body presses the first bus bars of the moving connector part upwards such that a binding force can be increased. Therefore, the bus bars can be effectively prevented from being disconnected even when an external vibration or shock arises.

The present invention relates to an electric charging system of a mechanical parking facility capable of stably supplying electric power to an electric vehicle even if external shocks and vibrations occur, and electric charging to an electric vehicle can be performed accurately and quickly only by moving a pallet.

In recent years, as the vehicle penetration rate increases and the city center is expanded, the lack of parking spaces has emerged as a serious problem, and as one of the solutions to this problem, mechanical parking facilities are widely installed.

This mechanical parking facility is a facility to provide a parking space by safely inducing the entry and exit of vehicles using a mechanical device.It is installed in a building where a large amount of parking space cannot be secured and is used for the purpose of securing the quantity of parking spaces. According to the operation method, it is classified into an elevator type, a flat reciprocating type, and a multi-storey circulation type.

In general, mechanical parking facilities move a pallet placed in one of the currently vacant parking spaces (locations) to the entrance and exit, and when a vehicle requesting entry is loaded on the pallet arranged at the entrance/exit, the pallet is moved to the corresponding parking position. It is operated by moving the vehicle to the parking position where the vehicle is parked, and moving the pallet back to the entrance and exit when requested to leave the vehicle.

On the other hand, in recent years, interest in electric vehicles (EVs) that use electric energy stored in batteries rather than using conventional petroleum power sources is increasing rapidly.

Such an electric vehicle (EV) includes a vehicle body and accessory equipment provided in a conventional vehicle, a battery that is charged with electricity, an electric motor that generates power using electric power charged in the battery, and is installed on one side of the vehicle body. When the battery is discharged because it consists of a charging connector connected to the charging plug, it is impossible to drive the vehicle, so it is necessary to periodically charge the battery, and accordingly, various studies on the electric charging system for supplying power to the electric vehicle are in progress. Has become.

However, research on the technology for supplying electric power to the electric vehicle in the parking space of the mechanical parking facility by introducing the electric charging facility to the mechanical parking facility is still very insufficient.
