Description

Technical Field

[0001] The utility model relates to the technical field of parking locks, in particular to a lifting plate 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

[0005] The purpose of the utility model is to propose a lifting plate type swing arm mechanism and a curb lock in view of the deficiencies of the prior art, so as to achieve adjustment of the height direction of the top of the swing arm mechanism, thereby effectively preventing vehicles from evading tolls in a locked state and improving the practicality of the curb lock.

[0006] The technical solution to achieve the purpose of this utility model is:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] In order to better understand the above technical solutions, the following will detail the above technical solutions in conjunction with the accompanying drawings of the specification and specific embodiments.

[0040] (Embodiment 1)

[0041] The curb lock of this embodiment adopts as Figures 1 to 4The shown lifting plate swing arm mechanism includes a main body 1 with a hollow structure and a lifting plate 2 movably arranged on the top of the main body 1. The main body 1 can be a closed structure or an open structure. A pair of synchronously operating lifting mechanisms 3 are arranged along the length direction inside the main body 1. The top of the lifting mechanism 3 is movably connected to the lifting plate and is adapted to drive the lifting plate 2 to move up and down, thereby realizing the adjustment of the height direction of the top of the swing arm mechanism, effectively preventing vehicles from evading tolls in the locked state of the vehicle, and improving the practicability of the curb lock.

[0042] Specifically, a base 4 is fixedly arranged at the bottom of the inner cavity of the main body 1. A driving motor 5 is fixedly installed on the side of the base 4. The output end of the driving motor 5 is arranged horizontally and coaxially fixed with a lead screw 6, forming a lead screw driving mechanism. The lifting plate 2 includes an upper cover top plate 2-1 and a connecting plate 2-2 fixedly arranged at the bottom of the upper cover top plate 2-1. The lifting mechanism 3 includes a pair of support arms 3-1. The upper ends of the two support arms 3-1 are hinged on the same long pin shaft. The connecting plate 2-2 is symmetrically arranged on both sides of the lifting mechanism 3 and is provided with strip-shaped chutes 2-2-1 extending along the length direction. The two ends of the long pin shaft respectively extend into the corresponding strip-shaped chutes 2-2-1, thereby realizing the movable connection of the upper ends of the support arms 3-1 and the connecting plate 2-2 along the length direction. The lead screw 6 in this embodiment is a forward and reverse lead screw. The lower ends of the outer support arms 3-1 of the two lifting mechanisms 3 are hinged with a fixed seat 7 fixedly connected to the base 4. The lower ends of the support arms 3-1 near the middle are hinged with a moving nut 8. The lead screw 6 passes through the fixed seat 7 and the moving nut 8. The fixed seat 7 is rotatably connected to the lead screw 6. The two moving nuts 8 are respectively in threaded cooperation with the positive and negative threads on the lead screw. Thus, when the driving motor 5 drives the lead screw 6 to rotate, the two moving nuts 8 move in opposite directions, and then the lifting action is realized through the support arms 3-1, realizing the rising and falling of the lifting plate 2.

[0043] In order to improve the smoothness of the lifting movement, a rotating bearing is arranged in the area corresponding to the strip-shaped chute 2-2-1 of the long pin shaft in this embodiment. The inner ring of the rotating bearing is fixedly connected to the long pin shaft 2-2-1, and the outer ring is provided with an annular groove corresponding to the strip-shaped chute 2-2-1, thereby reducing the friction force of the contact surface during relative movement and making the movement smoother.

[0044] Considering that the chassis of some vehicle models is relatively low, a rubber buffer pad is covered on the top of the lifting plate 2 in this embodiment to avoid collisions when the vehicle with a too low chassis rises on the lifting plate 2, causing an accident illusion to the people in the vehicle, and reducing unnecessary disputes.

[0045] At the end of the main body 1, a rotating wheel 9 is floatingly arranged longitudinally. The bottom of the rotating wheel 9 protrudes from the bottom of the main body 1, so that the swing arm mechanism can play a certain shock-absorbing function when encountering an uneven road section during the extension process, effectively protecting the components inside the main body 1. Specifically, a mounting seat 10 is fixedly installed at the top of the inner cavity of the main body 1. A hub bracket 11 is provided at the lower end of the mounting seat 10, and strip-shaped holes extending longitudinally are opened on both sides. A spring 12 is fixedly connected between the top of the hub bracket 11 and the mounting seat 10. The rotating wheel 9 is installed on the hub bracket 11, and the wheel axle of the rotating wheel 9 is inserted into the strip-shaped hole.

[0046] (Embodiment 2)

[0047] The structure of this embodiment is similar to that of Embodiment 1, except that the lead screw 6 in this embodiment is a co-directional lead screw, that is, there is only a thread rotating in the same direction on the lead screw. The fixed seats 7 are respectively hinged to the lower ends of the support arms 3-1 on the left side, and the moving nuts 8 are hinged to the lower ends of the support arms 3-1 on the right side. When the driving motor 5 drives the lead screw 6 to rotate, the two moving nuts 8 translate in the same direction, and then the lifting action is realized through the support arms 3-1, realizing the rising and falling of the lifting plate 2.

[0048] (Embodiment 3)

[0049] The structure of this embodiment is similar to that of Embodiment 1, except that as Figure 5 shown, the upper ends of the support arms 3-1 of the two sets of lifting mechanisms are hinged to the connecting plate, and the lower ends are respectively hinged with moving nuts 8. The lead screw 6 is provided with threads arranged alternately in positive and negative directions and is respectively in threaded transmission connection with the corresponding moving nuts 8. By driving the lead screw to rotate through the driving motor 5, the lower ends of the two support arms 3-1 of each set of lifting mechanisms translate in opposite directions at the same time, and the upper ends remain stationary, thus realizing the jacking effect.

[0050] (Embodiment 4)

[0051] The structure of this embodiment is similar to that of Embodiment 3, except that as Figures 6 to 7 shown, there is one set of lifting mechanisms, including two relatively arranged support arms 3-1. The upper ends of the two support arms 3-1 are both hinged to the connecting plate 2-2 and are spaced apart. The lower ends are hinged with moving nuts 8 with opposite threads. The lead screw 6 is a positive and negative lead screw and penetrates through the moving nuts 8 and is in threaded transmission connection with the corresponding moving nuts 8. By driving the lead screw to rotate through the driving motor 5, the lower ends of the two support arms 3-1 translate in opposite directions at the same time, and the upper ends remain stationary, thus realizing the jacking effect. Since the upper ends of the support arms 3-1 are spaced apart, the balance of the lifting plate 2 is maintained.

[0052] The utility model drives the lifting plate 2 to move up and down through the lifting mechanism 3, so as to realize the adjustment of the height direction of the top of the swing arm mechanism, effectively prevent vehicles from evading tolls in the locked state of the vehicle, and improve the practicability of the curb lock.

[0053] In the above specific embodiments, the purpose, technical solution and beneficial effects of the present utility model have been further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
