Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to 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 utility model patent application with application number 202322392927.1 provides a track curb lock that can be directly installed on the curb of a side parking space, including 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 the front and rear wheels of the car in the parking space to achieve a car locking function.

[0004] When there are foreign objects blocking the road, the swing arm mechanism will be hit by foreign objects during the rotation process. Multiple impacts will cause the connection to deform and become unusable. Or if some toll-doing vehicles directly run over the swing arm mechanism, the connection will also be deformed and fail. Therefore, further improvements need to be made to the existing structure. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] (Example 1)

[0035] like Figures 1 to 5 The curb lock shown includes a box assembly 1 and a swing arm mechanism 2 and a driving mechanism 3 arranged in the box assembly 1. The box assembly 1 is a rectangular structure with an opening on the side. The swing arm mechanism 2 is arranged opposite to the opening, and includes a connecting assembly 2-1 and a stop arm assembly 2-2 that are fitted and flexibly connected. The connecting assembly 2-1 and the driving mechanism 3 are both rotatably connected to the box assembly 1. The output end of the driving mechanism 3 is rotatably connected to the connecting assembly 2-1, and is used to drive the connecting assembly 2-1 to rotate, thereby driving the stop arm assembly 2-2 connected thereto to rotate, so as to extend the box assembly 1 to block the wheel from moving forward to lock the vehicle, or retract it into the box assembly 1 to unlock the vehicle.

[0036] Specifically, the barrier arm assembly 2-2 includes a barrier arm body 2-2-1 with a hollow structure, a flexible connection part 2-3 is provided in the barrier arm body 2-2-1, and the flexible connection part 2-3 includes a steel cable connection part 2-3-1 and a spring connection part 2-3-2 which are connected to each other, the other end of the spring connection part 2-3-2 is connected to the barrier arm body 2-2-1, and the other end of the steel cable connection part 2-3-1 extends to the connection assembly 2-1 and is connected to the connection assembly 2-1. The connecting component 2-1 includes a rotating member 2-1-1 and a fixed plate 2-1-2 which are fixedly connected to each other. A rotating pin 2-4 is longitudinally penetrated on the rotating member 2-1-1 and is limitedly installed between the top and the bottom of the box assembly 1. The other ends of the steel cable connecting part 2-3-1 and the spring connecting part 2-3-2 are respectively connected with a first limit pin 2-5 and a second limit pin 2-6. The first limit pin 2-5 is limitedly installed on the side of the fixed plate 2-1-2 away from the barrier arm assembly 2-2, and the second limit pin 2-6 is limitedly installed between the top and the bottom of the barrier arm body 2-2-1, thereby realizing the connection between the flexible connecting part 2-3, the connecting component 2-1 and the barrier arm assembly 2-2. The structure is simple and the installation is convenient.

[0037] By adopting a structure combining the steel cable connection part 2-3-1 and the spring connection part 2-3-2 as a flexible connection part to replace a separate spring structure, the spring failure that occurs when the swing arm is twisted can be effectively solved while achieving a flexible connection, so that the reset performance of the flexible connection part is better. When a separate spring structure is adopted, the spring will also bend while being stretched, and when the stretching deformation reaches a certain degree, it will become plastic deformation, causing the spring to fail and unable to reset, causing the swing arm to drag on the ground; when the structure of this embodiment is adopted, the spring connection part 2-3-2 only participates in the telescopic movement and does not participate in the twisting of the swing arm. In this way, when the swing arm is twisted, its deformation is compensated and absorbed by the steel cable connection part 2-3-1. When the torque is eliminated, the spring connection part 2-3-2 straightens the steel cable connection part 2-3-1 to achieve reset.

[0038] A fixed sliding block 2-7 and a movable sliding block 2-8 that are in close contact with each other are fixedly provided on the corresponding surfaces of the fixed plate 2-1-2 and the barrier arm body 2-2-1, respectively; a conical platform that protrudes toward one side of the fixed plate 2-1-2 is provided on the surface of the movable sliding block 2-8 that is in close contact with the fixed sliding block 2-7, and a groove that matches the conical platform is provided on the fixed sliding block 2-7. On the one hand, support is provided for the barrier arm assembly 2-2, the deadweight of the barrier arm assembly 2-2 borne by the flexible connection part 2 is reduced, and the service life of the flexible connection part 2-3 is extended; on the other hand, a certain positioning effect can be provided for the barrier arm assembly 2-2 when the barrier arm assembly 2-2 is reset by abnormal external force, so as to keep it aligned with the connection assembly 2-1.

[0039] In order to further improve the flexibility while ensuring the supporting force of the flexible connection part 2-3, the flexible connection part 2-3 of this embodiment is evenly arranged in two groups around the axial direction of the barrier arm assembly 2-2. The steel cable connection part 2-3-1 of each group of flexible connection parts 2-3 is a flat ring structure arranged in a closed loop, and the end close to the connection assembly 2-1 is smaller than the other end. Compared with a single thick steel cable structure, it has better flexibility.

[0040] In order to ensure sufficient driving force, the driving mechanism 3 of this embodiment is an electric push rod rotatably connected to the main body and the inner wall of the box assembly 1, and the push rod end of the electric push rod is rotatably connected to the rotating member 2-1-1. The electric push rod is extended and retracted, thereby driving the rotation of the rotating member 2-1-1, thereby realizing the rotation of the connecting assembly 2-1.

[0041] In order to further reduce the phenomenon of vehicles evading tolls, a plurality of car-blocking nails 2-9 that are telescopically arranged in the longitudinal direction are evenly arranged inside the arm body 2-2-1 of this embodiment. Specifically, mounting holes corresponding to the car-blocking nails 2-9 are evenly arranged at the top of the arm body 2-2-1 along the length direction. The car-blocking nails include a fixing member 2-9-1 that is vertically fixedly installed between the top and bottom of the inner wall of the arm body 2-2-1. A telescopic hole that is coaxially arranged with the mounting hole is arranged in the middle of the fixing member 2-9-1. Conical nails 2-9-2, telescopic springs 2-9-3 and plugs 2-9-4 that are arranged in a continuous manner are arranged in sequence from top to bottom in the telescopic hole. The plugs 2-9-4 are fixedly arranged at the bottom of the telescopic hole. The conical nails 2-9-2 extend to the outside of the mounting hole. When a vehicle runs over, the conical nails 2-9-2 retract into the telescopic hole without damaging the tire.

[0042] In this embodiment, the driving mechanism 3 drives the connecting component 2-1 installed on the box component 1 to rotate, thereby driving the barrier arm component 2-2 connected to it to extend and retract into the box component 1. The barrier arm component 2-2 and the connecting component 2-1 are flexibly connected. When the barrier arm component 2-2 encounters an obstacle such as a wheel during the process of extending or retracting, the barrier arm component 2-2 is restricted and cannot rotate. The connecting component 2-1 can still continue to rotate under the action of the driving mechanism 3, thereby preventing the whole machine from being restricted and stuck. At the same time, it can also prevent the swing arm mechanism 2 from being damaged when a vehicle evades the fee, effectively protecting the whole machine and extending its service life.

[0043] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
