In the initial state, the parking plate in the lifting space is located in the through groove and the upper surface is at the same height as the upper surface of the parking disk. The lifting system is activated to drive the parking plate to move upward to the second-floor parking space, so that the inner end of the parking plate is connected to the rotating system. After that, the rotating system is activated to drive the parking plate to rotate, and the parking plate where the electric vehicle is parked is rotated to the outside of the lifting space, and the parking plate where no electric vehicle is parked is moved to the corresponding lifting space.

[0069] Working principle:

[0070] When the owner needs to park the electric vehicle, he can enter the parking space by scanning the QR code on the control panel. If the vehicle is parked on the first floor, the owner can directly push the vehicle into the corresponding parking space on the first floor.

[0071] If the parking space on the first floor is full or the owner wants to park on the second floor, push the car into the parking board in the lifting space and start the lifting system. After receiving the command, the system detects that there is a car on the parking board through the pressure sensor, and brings the car and the parking board to the second floor through the lifting frame. The photoelectric sensor detects the height of the parking board, and specifically detects the position of the lifting frame. At this time, the first arc rack and the second arc rack extend, and the lifting frame descends; the rotating wheel drives the second-floor parking space to rotate, and the empty parking board on the second floor is turned to the corresponding position of the lifting frame. At this time, the lifting frame rises to the parking board position, and the first arc rack and the second arc rack are collected; the lifting frame brings the empty parking board to the through slot on the first floor and waits for the next owner to arrive. The parking process is over, and the process of picking up the car is similar to the parking process, and the system can run in reverse. If the owner needs to charge, he needs to select through the control panel, and pay the required charging time through Alipay or WeChat. Then push the car into the parking space, and the system will automatically power off after charging is completed.

[0072] Specifically, the line in the device is long enough, and the maximum rotation angle is 180 degrees, which will not cause the line entanglement problem.

[0073] Embodiment 2:

[0074] The parking garage can be used in large shopping malls, residential areas and other places where land resources are scarce, and can be widely promoted. It saves area, manpower and material resources, and has significant economic benefits.

[0075] Economic Analysis

[0076] Roughly calculated, a set of equipment costs 35,000 yuan and has a service life of 8 years. The equipment is fully loaded with 15 cars, with a parking space utilization rate of 80%, an average parking time of 3 hours, and a charging fee of 1 yuan per hour and a parking fee of 2 yuan per car.

[0077]

[0078] It can be seen that the parking garage has certain economic benefits and promotion value.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
