Description

Technical Field

[0001] The utility model relates to the technical field of barriers, in particular to a license plate recognition mechanism and a barrier with an adjustment structure. Background Art

[0002] The barrier gate, also known as a vehicle blocker, is a channel entrance and exit management device specially used to restrict the travel of motor vehicles on the road. It is now widely used in highway toll stations and parking lot systems to manage vehicle channels and to manage the entry and exit of vehicles. The electric barrier gate can raise and lower the bar through wireless remote control alone, or it can be automatically managed through the IC card swiping system. Vehicles are released by picking up the card when entering the gate, and automatically released after collecting the parking fee when leaving the gate.

[0003] Chinese patent announcement number: CN220117072U discloses a barrier direction adjustment structure of a license plate recognition integrated machine, including a barrier machine, a column installed on the front side of the barrier machine, and a threaded rotating rod installed on the right side of the inside of the first protective square box through the output end of the second servo motor. The utility model provides a barrier direction adjustment structure of a license plate recognition integrated machine. Through the driving action of the threaded rotating rod at the output end of the second servo motor at the bottom of the first protective square box, the second protective square box can be driven to move up and down along the limit rod, and the second protective square box can be extended upward when detection is required. The identification camera cooperates with the barrier machine to work, and the inside of the first protective square box can be retracted when not working. When there is dust on the surface of the identification camera, the detection area is unclear and the brush plate can be driven by the third servo motor to brush the dust, which effectively solves the problem that the existing barrier direction adjustment structure based on the license plate recognition integrated machine provided by it does not have a protective cleaning structure.

[0004] It can be seen that in the prior art, a cleaning structure is installed to clean the camera and improve the recognition of the camera. However, if the camera is installed in an inappropriate position, even if the camera is kept clean, it is difficult to accurately identify the vehicle. Most of the existing license plate recognition mechanisms are fixedly installed, and the camera's shooting angle and position need to be adjusted before installation. However, due to the different entry positions and sizes of vehicles, the camera's field of view may not be placed at the optimal recognition position and angle when shooting, which can easily cause recognition failure. Utility Model Content

For this reason, a license plate recognition mechanism and a barrier gate with an adjustment structure are proposed.

[0011] In a specific embodiment, the support mechanism comprises an annular sleeve slidably connected to the screw rod, support plates are arranged on both sides of the annular sleeve, and a support member is slidably arranged on one side of the support plate.

[0016] The license plate recognition mechanism and barrier gate with an adjustment structure provided in the embodiment of the utility model have the following advantages compared with the prior art:

[0017] 1.
