Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to a flap type swing arm mechanism and a curb lock. Background Art

[0002] At present, due to the annual increase in the number of cars in cities, the pressure of urban parking is increasing, and the problem of parking difficulty is becoming increasingly serious. In order to alleviate the pressure of urban parking, more and more urban roads have been developed into side-to-side paid parking spaces, but the existing urban transportation service infrastructure is still imperfect. There are two main ways to charge parking fees in the traditional way. One is to use manual charging, which has a relatively high labor cost and is prone to omissions and irregular charging. The other is to use an unattended intelligent parking system, that is, relying on a high-definition camera with built-in powerful image recognition + a mobile management terminal, automatically recording and notifying parking users to pay. This method also has the problem of expensive camera systems and high layout costs. In addition, since there is no parking lock, payment depends entirely on the self-consciousness of parking users and cannot be mandatory.

[0003] The Chinese utility model patent with authorization publication number CN220868053U discloses a track curb lock that can be directly installed on the curb of a side parking space. It includes a track and a control mechanism and a swing arm mechanism installed in the track. One end of the swing arm mechanism is rotatably connected to the control mechanism, and under the action of the control mechanism, the other end is rotated 90° around the connection point to achieve a vertical setting with the track, blocking between the front and rear wheels of the car in the parking space to achieve a car locking function.

[0004] The swing arm mechanism of this structure has a relatively low height. Even if it is opened to block the front and rear wheels, vehicles that want to evade tolls can still easily run over the swing arm mechanism. Therefore, it is necessary to optimize the structure of the existing swing arm mechanism. Utility Model Content
