Description

Technical Field

[0001] This application relates to the technical field of parking lots, and in particular to an intelligent parking lot license plate recognition device. Background Art

[0002] With the continuous progress of the times, vehicles have entered every family. The number of cars in the city increases year by year. Parking lots are set up in major shopping malls, residential communities or other places with a large number of the public. The parking lots in residential communities are for the owners to park their cars. The vehicles of the owners are registered in advance to prevent foreign vehicles from entering the residential parking lot and affecting the parking order. Generally, a license plate recognition device is used to recognize the license plates of vehicles.

[0003] After retrieval, a patent with the Chinese patent authorization announcement number CN115631542A discloses an intelligent parking lot license plate recognition device, which includes a main body mechanism, an adjustable rainshield recognition mechanism and an electric control limit mechanism. The adjustable rainshield recognition mechanism is located above the main body mechanism.

[0004] The above-mentioned intelligent parking lot license plate recognition device has the following deficiencies: Although the device is convenient for adjusting the recognition angle of the license plate recognizer and increases the flexibility of the license plate recognition device, after the vehicle recognizer of the device has been used for a long time, it needs to be disassembled and maintained or replaced. Moreover, since there is no device on the device that can be quickly installed and disassembled, the convenience during installation and disassembly is not high, which affects the work efficiency. In addition, the height of the vehicle recognizer of the device is fixed. When it is necessary to adjust according to different environments, it is rather troublesome and cannot be applied to vehicles of different heights, which affects the license plate recognition effect. Utility Model Content

[0005] The purpose of the present utility model is to solve or at least alleviate the problem in the prior art that due to the lack of a device for quick installation and disassembly on the device, the convenience during installation and disassembly is not high, which affects the work efficiency.

[0041] The implementation principle of this application is as follows: During use, the installer installs the license plate recognition device at a suitable position through the through hole 2. When a vehicle enters the recognition area of the vehicle identifier 20, the vehicle identifier 20 recognizes the vehicle license plate. After successful recognition, the vehicle identifier 20 sends a signal to the first motor 6. After the first motor 6 is started, the transmission end drives the gate plate 10 to rotate clockwise, so that the gate plate 10 moves away from the ground to release the vehicle. When it is necessary to adjust the recognition angle and height of the vehicle identifier 20, by starting the second motor 12, the output end of the second motor 12 will drive the screw rod 16 to rotate.

The rotation of the two first rotating plates 25 will drive the two second rotating plates 26 to rotate accordingly and drive the two half gears 27 to move away from each other. The two half gears 27 moving away from each other will drive the two rack plates 28 and the two positioning plates 29 to move away from each other accordingly, thereby releasing the fixed installation of the vehicle identifier 20. Therefore, the vehicle identifier 20 can be disassembled, replaced or maintained quickly and conveniently, improving the convenience and working efficiency during use.
