Detailed Description
The automatic parking and wireless charging system for electric vehicles according to the present application may include a server configured to establish and store occupancy information of a parking space of a parking lot. The server, which is not depicted in the figures, may be located either at the parking lot site or separately from the parking lot site, and may be communicatively connected to the automated guided vehicle 10 via a network. It is also possible that the automated guided vehicle 10 itself has the function of intelligently searching and selecting a parking space without having to be provided with a separate dedicated server.
The automatic guided vehicle 10 may also be referred to as an automatic guided vehicle, or the like, which is abbreviated as AGV in english. For example, the automated guided vehicle 10 may be equipped with an electromagnetic or optical automated guide device that can travel along a defined guide path. The automated guided vehicle 10 is typically powered by a power battery.
Advantageously, the automated guided vehicle 10 can be configured for communication connection with a server and can obtain information from the server of the free parking space 40 adapted to the electric vehicle 30 to be parked. The mobile platform 20 is designed for carrying an electric vehicle 30, can be connected to the automated guided vehicle 10 and thus can be transported by the automated guided vehicle 10, and can be disconnected from the automated guided vehicle 10 in order to be able to continue to carry on further work tasks after the current parking task has been completed. The automatic guided vehicle 10 can transport the movable platform 20 on which the electric vehicle 30 to be parked is mounted to a predetermined parking space 40, and can output the movable platform on which the electric vehicle to be taken away is mounted from the predetermined parking space.
It is possible that in the parking area, the respective mobile guide vehicles not only take on the task of parking the electric vehicle on the predetermined parking space, but also take on the task of taking the electric vehicle off the predetermined parking space. It is also possible for the respective mobile vehicles to share one another, wherein at least one of the automatic vehicles is responsible for the task of parking the electric vehicle on the predetermined parking space and at least one other automatic vehicle is responsible for the task of removing the electric vehicle from the predetermined parking space.
Fig. 1 is a schematic view of an automatic parking and wireless charging system according to the present application when an automatic guided vehicle 10 is about to engage a movable platform 20. Fig. 2 is a schematic view of the automatic parking and wireless charging system according to the present application when the automatic guided vehicle 10 is transporting the movable platform 20 to the predetermined parking space 40. The electric vehicle 30 to be parked is mounted on the movable platform 20 at a predetermined position of the parking lot, and the empty automatic guided vehicle 10 can be moved under the movable platform 20, for example, according to an instruction of the server. Then, the automated guided vehicle 10 lifts up the movable platform 20 on which the electric vehicle 30 to be parked is mounted, and automatically conveys the movable platform 20 on which the electric vehicle 30 to be parked is mounted to a predetermined parking space 40 based on information of the free parking space 40 adapted to the electric vehicle to be parked acquired from the server.
Fig. 3 is a schematic view of a mobile platform 20 of an automatic parking and wireless charging system according to the present application. The plug-in device 22 and the primary winding 21 electrically connected to the plug-in device are visible. The plug-in device 22 is designed to be electrically connected to a power supply connection 41 of the parking space 40. The primary coil 21 is configured to couple with a secondary coil 31 of an electric vehicle.
Fig. 4 is a schematic illustration of the automatic parking and wireless charging system according to the application when the plug-in device 22 is to be plugged into the power supply interface 41 on the respective parking space 40. The plug-in device 21 can be automatically electrically connected to the power supply interface 41 when approaching the power supply interface 41 of the parking space 40. For this purpose, for example, sensors, which can be cameras, radar or lidar, for example, can be provided on the parking space, on the automated guided vehicle or on the mobile platform. The position of the plug-in device 22 is detected by the sensor, so that the automatic guided vehicle 20 is moved in a controlled manner, so that the plug-in device 22 is plugged into the power supply interface 41 automatically. Alternatively or additionally, the plug-in device 22 can be automatically electrically connected to the power supply interface by magnetic force between the power supply interface and the plug-in device when approaching the power supply interface 41 of the parking space. The power interface may be configured as a socket and the plug-in device may be configured as a plug, or vice versa.
It is particularly advantageous if the plug-in device 22 is configured to be controllably movable between a concealed position in which it is concealed within the movable platform and an operative position in which it protrudes from the movable platform. The plug-in device 22 can be held in a concealed position during transport of the mobile platform 20 by the automated guided vehicle 10 and can only be extended from the concealed position into the operating position when it is to be plugged into the power supply interface 41. If the electric vehicle does not have a charging requirement or if the vehicle to be parked is not an electric vehicle with a wireless charging function, the plug-in device 22 can remain in the concealed position at all times.
When the electric vehicle is automatically parked on a preset parking space, the electric vehicle can be automatically and wirelessly charged according to the requirement. At this point, the automated guided vehicle 10 may be disconnected from the mobile platform 20 and perform other work tasks. Thus, only a limited number of automated guided vehicles are required for the entire parking area, and the number of automated guided vehicles can be appropriately selected according to a predetermined traffic volume of parking traffic of the parking area.
When the parked electric vehicle is to be removed, if the plug-in device 22 is plugged into the power source interface 41, the plug-in connection of the plug-in device 22 to the power source interface 41 is first disconnected, which can be achieved, for example, by a controlled movement of the automatic guided vehicle 10. The automated guided vehicle 10 transports the movable platform 20 together with the onboard electric vehicle 30 from the parking space 40 to a predetermined position so that the owner of the electric vehicle takes away the electric vehicle 30.
As shown in fig. 3 and 4, the movable platform 20 has a single primary coil 21. It is also possible that the movable platform 20 has a plurality of primary coils arranged in a distributed manner, which can be selectively activated. It is advantageous for the wireless charging of the electric vehicle that the primary coil 21 and the secondary coil 31 are as close as possible. It is therefore desirable that the one of the plurality of primary coils that is closest to the secondary coil 31 can be activated in order to achieve optimal wireless charging.
As shown in fig. 4, the power interface 41 is provided on a wall. Alternatively, the power interface 41 may be provided on the vertical rod or other suitable location. It is also possible that the power supply interface 41 is arranged hidden in the ground and only extends from the hidden position in the ground to the operating position in a controlled manner when a point connection to the plug-in device 22 is required, and can be retracted from the operating position to the hidden position in the ground as required.
As shown in fig. 1 and 2, the automated guided vehicle 10 is capable of transporting a movable platform 20 under the movable platform. Alternatively or additionally, the automated guided vehicle 10 may also pull in front or push the movable platform 20 in the rear.
Finally, it should be pointed out that the above-described embodiments of the application are only intended to be understood as examples of the application, without limiting the scope of the application. Modifications can be made to the above embodiments by those skilled in the art, all without departing from the scope of the application.
