Description

Technical Field

[0001] The present invention relates to the technical field of buildings for special purposes, and in particular to an intelligent curb lock for parking space fee management. Background Art

[0002] With the explosive growth in car ownership, the difficulty of finding parking, particularly in cities, is a real problem plaguing everyone. To alleviate this difficulty, it has become common practice for cities to mark parking spaces on the sides of some roads. Roadside parking fees have generally transitioned from traditional manual tolling to the use of corresponding parking space management devices to replace manual tolling. Parking locks located near the curb or on the curb are the most widely used due to their advantages such as easy installation, small footprint, and no obstruction to road traffic. Typical curb locks include a side-mounted intelligent curb lock device disclosed in patent publication number CN 208136773U and a track curb lock disclosed in patent publication number CN220868053U. Their common feature is that they use an extendable and retractable barrier arm to limit the tires of parked vehicles, forcing or reminding the owner to pay by scanning a code. However, in actual use, it was found that the current curb parking locks have the following common defects and shortcomings: First, since the current curb parking locks are generally installed in the middle of the curb on one side of the roadside parking space (along the direction of road traffic), they can be effectively used for vehicles that park regularly in the parking space, but it is difficult to lock and charge vehicles that are parked in the middle of the two adjacent parking spaces in front and behind for malicious evasion of fees; second, in order to maliciously evade fees, the wheels are deliberately used to block the vehicle blocking arm of the existing curb lock when parking, so that it cannot be extended to lock; third, when maliciously evading fees, when leaving the parking space, the vehicle is forced to pass over the vehicle blocking arm of the curb lock, causing damage to the vehicle blocking arm, requiring frequent disassembly and replacement of the vehicle blocking arm or curb lock; fourth, the lack of corresponding light prompts is not conducive to vehicle drivers noticing the parking lock to regulate parking and payment at night.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0046] See Figures 1 to 10 The smart curb lock of this embodiment is mainly composed of a lock body 1, a QR code nameplate 2, a parking detection sensor 3, a parking block arm driving mechanism 4, a parking block arm connecting mechanism 5, a parking block arm 6, a lighting component, a main controller (not shown in the figure) and a power module (not shown in the figure).

[0047] The lock body 1 is a long strip-shaped structural member, and a vehicle blocking arm accommodating groove 11 is provided below the outer side of the lock body 1 (the side facing the parking space when installed); what is significantly different from the lock body of the existing curb lock is that the length of the lock body 1 of this embodiment is close to the length of a roadside parking space in which it is installed, and is significantly longer than the lock body of the existing curb lock. This design is intended to solve the technical problem that the existing curb lock is difficult to lock and charge when a vehicle is parked between two adjacent parking spaces in front and behind for malicious evasion of tolls. Details will be described later.

[0048] The QR code nameplate 2 is fixedly arranged on one side of the upper end of the lock body 1, and is used for the owner to scan the code to pay when leaving the parking space. This is a mature existing technology and will not be described in detail.

[0049] The parking detection sensors 3 are used to detect the presence of a vehicle in a parking space, the parking position, and the parking duration. In this embodiment, five parking detection sensors 3 are provided as a priority. These sensors are located above and outside the lock body, from rear to front (the front of the vehicle is designated as forward, and the rear of the vehicle is designated as rearward). These sensors are referred to as the first sensor 31, the second sensor 32, the third sensor 33, the fourth sensor 34, and the fifth sensor 35. The parking detection sensors 3 can be commonly used commercially available sensors. Their operating principles are well-established and will not be elaborated on here.

[0050] See also Figures 3 to 5 In this embodiment, the car blocking arm driving mechanism 4 is used to drive the car blocking arm 6 to move forward and backward (along the length direction of the lock body) in the car blocking arm accommodating groove 11 of the lock body 1 to a position where it can extend from the lock body 1 to lock the car, and to extend the car blocking arm 6 (when parking is completed) and retract it (when payment is completed). As a specific implementation method, in this embodiment, the car-blocking arm driving mechanism 4 includes a travel driving component 41 and a car-blocking arm telescopic driving component 42, wherein the travel driving component 41 includes an upper rail 41-1 fixedly arranged along the length direction above the lock body 1, a travel driving motor 41-2 fixedly arranged in the lock body 1, a coupling 41-3 transmission-connected to the travel driving motor 41-2, a bearing 41-4 arranged in the upper rail 41-1 through a matching mounting seat, a screw rod 41-5 transmission-connected to the coupling 41-3 through the bearing 41-4, a screw rod nut 41-6 threadedly engaged with the screw rod 41-5, a lower rail 41-7 fixedly connected to the screw rod nut 41-6, and load-bearing rollers 41-8 arranged on both sides of the lower rail 41-7 and rollingly engaged with the upper rail 41-1. In this embodiment, two load-bearing rollers 41-8 are arranged on each side of the lower rail 41-7. Preferably, the travel drive assembly 41 further includes two limiting wheels 41-9 disposed on either side of the lower track 41-7 for limiting the travel direction of the lower track 41-7 to prevent deviation. The vehicle-blocking arm telescopic drive assembly 42 includes a mounting bracket 42-1 fixedly connected to the lower track 41-7 and a vehicle-blocking arm electric push rod 42-2 fixedly mounted on the mounting bracket 42-1. Preferably, the mounting bracket 42-1 and the lower track 41-7, as well as the vehicle-blocking arm electric push rod 42-2 and the mounting bracket 42-1, are fixedly connected by bolts to facilitate assembly and disassembly.

[0051] The car-blocking arm connecting mechanism 5 is used for the transmission connection between the car-blocking arm driving mechanism 4 and the car-blocking arm 6, so as to enable the car-blocking arm 6 to extend and retract outward from the car-blocking arm receiving groove 11 of the lock body 1. As a specific implementation method, in this embodiment, the car-blocking arm connecting mechanism 5 includes a rotating bracket 51, a rotating shaft 52 rotatably arranged on the rotating bracket 51, and a push rod connecting pin 53 fixedly arranged on the rotating bracket 51; the rotating bracket 51 is movably connected to the mounting connecting frame 42-1 of the car-blocking arm telescopic driving assembly 42 via the rotating shaft 52, and the push rod connecting pin 53 is transmission-connected to the car-blocking arm electric push rod 42-2 of the car-blocking arm telescopic driving assembly 42. During operation, the retraction and extension movement of the car-blocking arm electric push rod 42-2 allows the rotating bracket 51 to rotate inward and outward relative to the mounting connecting frame 42-1 of the car-blocking arm telescopic driving assembly 42 based on the rotating shaft 52. As a preferred embodiment, in this embodiment, the car-stop arm connection mechanism 5 further includes an anti-tilt bracket 54 fixedly mounted on the rotating bracket 51 and sleeved with the car-stop arm 6, as shown in FIG. Figure 10 As shown, the anti-roll bracket 54 includes a frame body 54-1, a protruding arm 54-2 provided on each side of the upper portion of the frame body 54-1, and two connecting ears 54-3 provided on the frame body 54-1; Figure 5 As shown, the anti-tilt bracket 54 is fixedly connected to the rotating bracket 51 by its two connecting ears 54-3, the frame body 54-1 of the anti-tilt bracket 54 is sleeved with one end of the anti-tilt arm 6, and the two protruding arms 54-2 of the anti-tilt bracket 54 limit the upper and lower sides of one end of the anti-tilt arm 6. The material of the anti-tilt bracket 54 is spring steel. The purpose of providing the anti-tilt bracket 54 is to solve the technical problem in the prior art that the anti-tilt arm of similar road tooth locks can be easily pushed back into the lock body by malicious toll evaders after opening, and the related components of the anti-tilt arm can be easily damaged. In this embodiment, after the anti-tilt bracket 54 is provided, due to the hard obstruction of the anti-tilt bracket 54, it is basically impossible to push the anti-tilt arm 6 back into the lock body 1 by human power. The anti-tilt bracket 54 is made of spring steel, which takes advantage of its considerable rigidity and self-recovery ability after deformation.

[0052] See also Figure 2 as well as Figures 5 to 10 The car-blocking arm 6 is connected to the car-blocking arm driving mechanism 4 through the car-blocking arm connecting mechanism 5, and is used to approach the chassis of the parked vehicle to achieve locking of the vehicle when in use. In this embodiment, one car-blocking arm 6 is provided. The car-blocking arm 6 includes a shell 61, a telescopic bracket 62 provided on the shell 61, a car-blocking frame 63 connected to the telescopic bracket 62, a car-blocking frame electric push rod 64 for raising and retracting the car-blocking frame 63 through the transmission of the telescopic bracket 62, an up-and-down unloading assembly 65 for unloading the force when the upper part of the car-blocking frame 63 is subjected to force, and an anti-twisting assembly 66 for preventing the car-blocking arm 6 from being deformed and damaged due to the forced passage of the wheel.

[0053] As a specific implementation method, the shell 61 is a structural member in the shape of a square tube as a whole, and corresponding first slide grooves 61-1 and second slide grooves 61-2 are respectively provided on the two side plates of the shell 61 along the length direction; the anti-vehicle frame 63 is a frame structural member with an inverted U-shaped cross-section, and a slide groove 63-1 is provided on each side of the anti-vehicle frame 63. As a preferred method, a rubber strip 63-2 is provided above the anti-vehicle frame 63 to achieve soft contact between the anti-vehicle frame 63 and the vehicle chassis when locking the vehicle to avoid damage to the vehicle. The telescopic bracket 62 includes four support arms 62-1, two sliding shafts 62-2, two fixed shafts 62-3 and two intermediate connecting pins 62-4. The four support arms 62-1 are arranged in an X shape on the outer sides of the two side plates of the shell 61 along the length direction, and each intersection is connected by an intermediate connecting pin 62-4. The upper and lower ends of each support arm 62-1 on both sides are respectively movably connected with one end of a sliding shaft 62-2 provided in the slide groove 63-1 of the anti-vehicle frame 63 and the first slide groove 61-1 of the shell 61. The upper and lower ends of each other support arm 62-1 on both sides are respectively movably connected with one end of a fixed shaft 62-3 fixed on the anti-vehicle frame 63 and the shell 61. The so-called dynamic connection here means that the support arm 62-1 can rotate relative to the sliding shaft 62-2 or the fixed shaft 62-3 connected to it. Preferably, the telescopic bracket 62 further includes a support reinforcement member 62-2-1 fixedly disposed within the housing 61 for assisting in the movement of a sliding shaft 62-2 disposed on the housing 61. The support reinforcement member 62-2-1 is a generally U-shaped plate member. The anti-vehicle frame electric push rod 64 is movably disposed within the housing 61 and is in transmission connection with the sliding shaft 62-2 disposed within the housing 61. During operation, the anti-vehicle frame electric push rod 64 performs telescopic movement, which, through the transmission of the telescopic bracket 62, causes the anti-vehicle frame 63 to be raised and lowered to reset.

[0054] See also Figure 6 and Figure 7 The vertical unloading assembly 65 is disposed in the housing 61 and is used to relieve pressure from above the vehicle stop frame 63 to prevent the vehicle stop frame electric push rod 64 from being damaged by pressure and the vehicle stop frame 63 from being too tightly pressed against the vehicle chassis, causing damage to the vehicle. As a specific implementation, in this embodiment, the vertical unloading assembly 65 includes two unloading springs 65-1, a first connecting rod 65-2 fixedly disposed on the vehicle stop frame electric push rod 64, and a second connecting rod 65-3 fixedly disposed in the housing 61. One end of each of the two unloading springs 65-1 is connected to the first connecting rod 65-2, and the other end of each of the two unloading springs 65-1 is connected to the second connecting rod 65-3.

[0055] The working principle and process of the up and down unloading assembly 65 are as follows: when the anti-vehicle frame 63 is subjected to force, the two ends of the four support arms 62-1 rotate relative to the shaft to which they are connected. At the same time, through the transmission of the telescopic bracket 62, the sliding shaft 62-2 arranged in the shell 61 slides on the first slide groove 61-1 of the shell 61, driving the anti-vehicle frame electric push rod 64 to move, and the first connecting rod 65-2 fixed on the anti-vehicle frame electric push rod 64 drives the two unloading springs 65-1 to stretch, thereby realizing unloading; when the pressure above the anti-vehicle frame 63 is eliminated, the two unloading springs 65-1 elastically reset to reset the anti-vehicle frame electric push rod 64.

[0056] See also Figures 6 to 9 The anti-twist assembly 66 is used to prevent the wheels of a malicious toll-doing vehicle from passing over the blocking arm 6 and damaging the blocking arm 6 when leaving the parking space. As a specific implementation method, in this embodiment, the anti-twist assembly 66 includes two anti-twist springs 66-1, a first connecting shaft 66-2, a second connecting shaft 66-3, two steel ropes 66-4, a movable slider 66-5, a fixed slider 66-6, and a connector 66-7. A protrusion 66-5-1 is provided on one side of the movable slider 66-5, and two rope holes 66-5-2 are provided on the movable slider 66-5; a recessed portion 66-6-1 whose shape matches the protrusion 66-5-1 of the movable slider 66-5 is provided on the side of the fixed slider 66-6 opposite to the movable slider 66-5, and two rope holes 66-6-2 are provided on the fixed slider 66-6. The connector 66-7 is a U-shaped structural member, and two rope holes are also provided on the connector. The fixed slider 66-6 is fixedly connected to the connecting member 66-7, the connecting member 66-7 is fixedly connected to the rotating bracket 51 of the anti-car arm connecting mechanism 5, the first connecting shaft 66-2 is fixedly arranged in the middle position of the housing 61, each end of the two anti-torsion springs 66-1 is connected to the first connecting shaft 66-2, the other end of each of the two anti-torsion springs 66-1 is fixedly connected to one end of a steel wire rope 66-4, the other end of each of the two steel wire ropes 66-4 passes through the rope hole 66-5-2 of the movable slider 66-5, the rope hole 66-6-2 of the fixed slider 66-6 and the rope hole of the connecting member 66-7 and is fixedly connected to the second connecting shaft 66-3, the second connecting shaft 66-3 is close to the connecting member 66-7, and one end of the housing 61 is fixedly connected to the movable slider 66-5.

[0057] The working principle and process of the anti-twist assembly 66 are as follows: when the vehicle arm 6 is in the extended blocking state, if a vehicle maliciously evading tolls directly impacts the vehicle arm 6 and drives out, when the wheel impacts the housing 61 of the vehicle arm 6, the movable slider 66-5 fixedly connected to the housing 61 rotates relative to the fixed slider 66-6, or even pulls out of the fixed slider 66-6 and rotates again. At this time, the two anti-twist springs 66-1 stretch to compensate for the distance difference caused by the displacement and deformation of the housing 61, thereby causing the vehicle arm 6 to fall in the direction of the wheel's advance, minimizing damage to the vehicle arm 6 caused by the wheel passing over the vehicle arm 6. When the wheel passes, the external force disappears, and the vehicle arm 6 automatically returns to its original position under the elastic restoring force of the two anti-twist springs 66-1. The two anti-torsion springs 66-1 are connected to the second connecting shaft 66-3 by two steel wire ropes 66-4, which utilize the twistable and bendable properties of the steel wire ropes to achieve the function of the anti-torsion springs 66-1 to resist the impact of the passing wheels and reset the vehicle arm 6.

[0058] See also Figure 1 The lighting assembly includes a solar panel 7 fixed on the lock body 1, a colored light strip 71 provided in the lock body 1 and above the car blocking arm accommodating groove 11, and a light strip controller provided in the lock body 1 and matched with the solar panel 7 (all three components are commercially available and their working principles are mature existing technologies). When working, the solar panel 7 provides power to the colored light strip 71 through the light strip controller and controls the lighting and extinguishing of the colored light strip 71. The lighting and extinguishing time of the colored light strip 71 controlled by the light strip controller can be set according to specific circumstances. In this embodiment, the controller controls the lighting and extinguishing time of the colored light strip 71 from 18:00 on the same day to 6:00 the next day. The solar panel 7, light strip controller, and colored light strip 71 are preferably configured. In this embodiment, by illuminating the colored light strip 71 at night, the solar panel 7, light strip controller, and colored light strip 71 clearly remind drivers of the presence of parking locks in roadside parking spaces, thereby alerting them to the locks and ensuring proper parking and payment procedures. Furthermore, the colored light strips 71 on each roadside parking lock also serve as landscape lights, enhancing the road's aesthetics. The lighting component provided in this embodiment is not commonly found in current curb locks of this type and represents one of the innovations of this intelligent curb lock.

[0059] The main controller and power module are located within the lock body 1. The power module provides the power required for the operation of the smart curb lock of this embodiment. This is a mature prior art and will not be described in detail. The main controller, like existing similar parking locks, serves as the overall control unit for the smart curb lock of this embodiment. Unlike the prior art, when installed in a curbside parking space, the main controllers of two adjacent smart curb locks of this embodiment communicate with each other. It should be emphasized that the structure and operating principle of the main controller itself, as well as the mutual communication between the two main controllers, are mature prior art and will not be described in detail. However, the smart curb lock of this embodiment innovatively establishes a communication connection between the main controllers of two adjacent smart curb locks, allowing the two adjacent smart curb locks of this embodiment to cooperate with each other to effectively lock and charge malicious evading vehicles parked between two adjacent parking spaces. This is a technology that similar curb locks of the prior art do not possess. The aforementioned parking detection sensors 3 are electrically connected to the main controller to send detection signals to the main controller. The travel drive motor 41-2 of the travel drive component 41 of the car-blocking arm drive mechanism 4, the car-blocking arm electric push rod 42-2 of the car-blocking arm telescopic drive component 42, and the car-blocking frame electric push rod 64 of the car-blocking arm 6 are all electrically connected to the main controller and are controlled to start and stop by the main controller. This is also a mature existing technology and will not be elaborated on.

[0060] See also Figure 11 and Figure 12 The working principle and process of the intelligent curb lock of this embodiment, which solves the four common technical problems of existing curb locks of the same type through structural design, are briefly described as follows:

[0061] The smart curb lock of this embodiment is fixedly installed on each side of each parking space near the curb. Figure 11 As shown, after the power is turned on, the main controllers of the two adjacent smart curb locks located on the first parking space 100 and the second parking space 101 automatically establish a communication connection. Figure 11The single arrow in the middle indicates the parking direction of the parking space. Taking the vehicle entering the first parking space 100 as an example, when the vehicle enters the first parking space 100, the first sensor 31 first sends a signal to the main controller of the smart curb lock on the parking space to inform that a vehicle has entered. When the vehicle is parked normally and in the middle of the first parking space 100, the second sensor 32, the third sensor 33, and the fourth sensor 34 send a signal to the main controller to inform the main controller that a vehicle is parked normally. The main controller controls the blocking arm 6 to extend outward from the blocking arm receiving slot 11 of the lock body 1 and then controls the blocking arm 6 to extend outward. The frame 63 rises upward and makes soft contact with the chassis of the parked vehicle to lock the vehicle. In this embodiment, the so-called upward rise of the anti-vehicle frame 63 and the soft contact with the chassis of the parked vehicle to lock the vehicle is controlled by the main controller to monitor the driving current of the anti-vehicle frame electric push rod 64 of the anti-vehicle arm 6. When the driving current of the anti-vehicle frame electric push rod 64 reaches the set threshold, the main controller determines that the vehicle is reliably locked, and the upper and lower unloading components 65 and the rubber strip 63-2 on the anti-vehicle frame 63 achieve soft contact between the anti-vehicle frame 63 and the car chassis, thereby achieving reliable locking of the parked vehicle. After the car owner scans the QR code plate 2, the main controller automatically sends the parking time and fee amount to the backend according to the method of the prior art, and the backend then sends it to the car owner's mobile phone. After the car owner pays, the main controller controls the blocking frame 63 of the blocking arm 6 to reset downward and reset the blocking arm 6 to the blocking arm receiving slot 11 of the lock body 1, thereby unlocking the parked vehicle that is about to leave. When the vehicle leaves the first parking space 100, the fifth sensor 35 sends a trigger signal to the main controller, and the main controller determines that the normal parking fee payment is completed. Obviously, due to the different specific parking positions of the normally parked vehicles on the first parking space 100, when the blocking arm 6 cannot be normally extended, the main controller controls the blocking arm 6 to move forward and backward to a certain position before unlocking.

[0062] The technical solution of the smart curb lock of this embodiment to solve the common technical problem of existing curb locks of the same type is briefly described as follows:

[0063] If a car owner parks his vehicle (especially a small car with a relatively short wheelbase) between the first parking space 100 and the second parking space 101, that is, across the parking space dividing line 103, in order to maliciously evade parking fees, it is difficult for existing curb locks of the same type to lock and charge fees. The smart curb lock of this embodiment can effectively solve this problem. Specifically, when a malicious evader parks across the parking space dividing line 103, the fifth sensor 35 of the smart curb lock located on the side of the first parking space 100 sends a detection signal to the main controller of the lock to detect that a car has parked. At the same time, the first sensor 31 of the smart curb lock located on the side of the second parking space 101 sends a detection signal to the main controller of the lock to detect that a car has parked. After the two adjacent smart curb locks confirm the above detection information through interactive communication, they determine that a car has maliciously parked across the parking space dividing line 103. At this time, if Figure 12As shown by the hollow arrow, the blocking arm 6 of the smart curb lock on the side of the first parking space 100 moves toward the rear of the parked vehicle, and the blocking arm 6 of the smart curb lock on the side of the second parking space 101 moves toward the front of the parked vehicle. There are three ways to lock the malicious parked vehicle: the first is that the blocking arm 6 of the smart curb lock on the side of the first parking space 100 reliably locks the rear chassis of the malicious parked vehicle; the second is that the blocking arm 6 of the smart curb lock on the side of the second parking space 101 reliably locks the front chassis of the malicious parked vehicle; the third is that the two smart curb locks reliably lock the rear chassis and the front chassis of the malicious parked vehicle at the same time. In this embodiment, the third locking method is preferred to realize the locking fee for malicious parked vehicles. The subsequent unlocking after payment is the same as above and will not be repeated. The use of two adjacent smart curb locks cooperating with each other to achieve reliable locking and charging for malicious parking across the parking space dividing line 103 to prevent malicious parking from evading fees is recorded in this paragraph. This is the core innovation of the present invention in solving technical problems that similar curb locks in the existing technology cannot solve.

[0064] The technical solution of the smart curb lock of this embodiment to solve the second common technical problem of similar curb locks is briefly described as follows:

[0065] If a car owner intentionally uses their wheel to block the position of the blocking arm 6 of the smart curb lock of this embodiment in order to avoid paying the fee, the smart curb lock of this embodiment solves the problem as follows: when the main controller of the smart curb lock of this embodiment detects that the driving current of the blocking arm electric push rod 42-2 of the blocking arm drive mechanism 4 reaches a set threshold, the main controller determines that the blocking arm 6 is blocked. At this time, the main controller drives the blocking arm 6 to move and change its position through the travel drive component 41 of the blocking arm drive mechanism 4, and then attempts to extend the blocking arm 6. If the blocking arm 6 still cannot be extended, the main controller continues to change the position of the blocking arm 6 until the blocking arm 6 can be successfully extended and unlocked. Therefore, the smart curb lock of this embodiment can effectively solve the technical problem of similar curb locks in the prior art that the blocking arm of the existing curb lock cannot be extended and locked by intentionally using the wheel to block the blocking arm of the existing curb lock when parking for malicious evasion of tolls.

[0066] The technical solution of the smart curb lock of this embodiment to solve the third common technical problem of existing curb locks of the same type is briefly described as follows:

[0067] By setting the anti-twist component 66 on the car stop arm, the car stop arm 6 can minimize the damage to the car stop arm 6 caused by the wheel passing over the car stop arm 6 when the car stop arm 6 is impacted by the wheel. The specific structure and principle are as mentioned above and will not be repeated here.

[0068] In addition, the intelligent curb lock of this embodiment can not only solve the common technical problem of existing curb locks of the same type by setting a lighting component, but also has the function of lighting and beautifying the road. The specific structure and principle are as mentioned above and will not be repeated here. Example

[0069] See also Figures 13 to 15 The intelligent curb lock of this embodiment is the same as that of embodiment 1 in other respects, except that: unlike embodiment 1 in which only one blocking arm 6 that can move along the length direction of the lock body 1 is provided, this embodiment is connected by four sets of blocking arm connecting mechanisms 5 along the length direction of the lock body (which is also the parking direction) in the blocking arm accommodating groove 11 of the lock body 1, and the four blocking arms 6, numbered one to four, are connected. Accordingly, the blocking arm driving mechanism 4 only retains the blocking arm electric push rod 42-2 of the blocking arm telescopic driving assembly 42 and fixes the four blocking arm electric push rods 42-2 in the lock body 1. The four sets of blocking arm connecting mechanisms 5 are fixedly connected to the lock body 1 by their rotating brackets 51, and each set of blocking arm connecting mechanisms 5 is transmission-connected to one blocking arm electric push rod 42-2.

[0070] Although the smart curb lock of this embodiment differs from the smart curb lock of Example 1 in structure, it can still achieve all the functions of the smart curb lock of Example 1, as briefly described below:

[0071] First, when the owner parks the car normally, one of the two blocking arms 6 located in the middle will lock the parked vehicle according to the specific parking position;

[0072] Second, when a car owner parks his vehicle across the parking space dividing line 103 in order to maliciously evade parking fees, the fourth blocking arm 6 of the smart curb lock on the first parking space 100 side, the first blocking arm 6 of the smart curb lock on the second parking space 101 side, or both blocking arms 6 are extended and opened simultaneously to lock the parked vehicle;

[0073] Third, when a car owner intentionally uses his wheels to block the position of the blocking arm 6 of the smart curb lock of this embodiment to maliciously evade parking fees, in order to block the blocking arm 6 so that it cannot be normally extended to open and lock the vehicle for charging, due to the limitation of the vehicle's wheels, the main controller of the smart curb lock attempts to open the first to fourth blocking arms in sequence. Since the vehicle wheels cannot block the four blocking arms 6 at the same time, there is always at least one blocking arm 6 that can be opened to effectively lock the vehicle.

[0074] Fourthly, the functions of the anti-twisting and up-down unloading force of the car-blocking arm 6 lie in the structure of the car-blocking arm 6 . In this embodiment, the structure of the car-blocking arm 6 is not changed, and the two functions are still available.

[0075] The above embodiments are illustrations of specific implementation methods of the present invention, rather than limitations of the present invention. Technicians in the relevant technical fields can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
