Description

Technical Field

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

[0002] With the explosive growth of the number of automobiles, currently, especially in cities, the problem of difficult parking is a realistic problem that troubles all parties. To alleviate this difficulty, it has become a common practice for cities to mark parking spaces on the side of some roads. The charging for roadside parking spaces has generally transitioned from traditional manual charging to charging through the installation of corresponding parking space management devices to replace manual charging. Among them, the parking space locks installed on the side or on the curb of roadside parking spaces are the most widely used due to their advantages such as convenient installation, less land occupation, and no obstruction to road traffic. For example, a side-mounted intelligent curb lock device disclosed in a patent document with the authorization announcement number CN 208136773U, and a rail curb lock disclosed in a patent document with the authorization announcement number CN220868053U are typical roadside parking space locks. Their common feature is to limit the tires of parked vehicles through retractable blocking arms to force or remind the vehicle owners to pay by scanning the code. However, in the actual use process, it is found that the current roadside parking space locks have the following common defects and deficiencies: First, since the current roadside parking space locks are generally installed in the middle of the curb on one side of the roadside parking space (along the road traffic direction), they can be effectively used for vehicles parked regularly in this parking space. However, for vehicles parked maliciously in the middle of two adjacent parking spaces to avoid payment, it is difficult to lock and charge them. Second, to avoid payment maliciously, when parking, the vehicle deliberately uses the wheels to block the blocking arm of the existing curb lock so that it cannot extend to lock. Third, when leaving the parking space maliciously to avoid payment, the vehicle forcibly drives over the blocking arm of the curb lock, causing damage to the blocking arm, and it is necessary to frequently disassemble and replace the blocking arm or the curb lock. Fourth, there is a lack of corresponding light prompts, which is not conducive to vehicle drivers noticing the parking space lock at night for regular parking and payment. Summary of the Invention

Each of the above intelligent curb locks is fixedly installed on each parking space on the roadside. Its structural feature is that the main controllers of the intelligent curb locks on two adjacent parking spaces communicate and cooperate with each other.

(5) The present invention innovatively provides a lighting component, which can significantly prompt the vehicle driver that there is a parking lock on the roadside parking space during use, facilitating the vehicle driver to notice the parking lock for standardized parking and payment. Thus, it effectively solves the common technical problem in the prior art that due to the lack of corresponding lighting prompts, it is not conducive for vehicle drivers to notice the parking lock at night for standardized parking and payment.

Detailed Description of the Invention

[0017] The present invention will be further described in detail below with reference to the drawings and specific embodiments. Embodiment

[0018] See Figures 1 to 10 , the intelligent curb lock of this embodiment mainly consists of a lock body 1, a QR code nameplate 2, a parking detection sensor 3, a blocking arm drive mechanism 4, a blocking arm connection mechanism 5, a blocking arm 6, a lighting component, a main controller (not shown in the figure), and a power supply module (not shown in the figure).

[0019] The lock body 1 is a long strip-shaped structural member, and a blocking arm receiving groove 11 is provided below the outer side of the lock body 1 (the side facing the parking space during installation); different from the lock body of the existing curb lock, the length of the lock body 1 in this embodiment is close to the length of a roadside parking space where it is installed, significantly longer than the lock body of the existing curb lock. Such a design is to solve the technical problem that it is difficult for the existing curb lock to lock and charge when a vehicle parks between two adjacent parking spaces in order to evade fees maliciously, as will be described later in detail.

[0020] 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 vehicle owner to scan the code and pay the fee when leaving the parking space. This is a mature existing technology and will not be elaborated here.

[0021] The parking detection sensor 3 is used to detect whether there is a vehicle parked in the parking space, the parking position, and the parking duration. As a preferred method, in this embodiment, five parking detection sensors 3 are provided. The five parking detection sensors 3 are respectively called the first sensor 31, the second sensor 32, the third sensor 33, the fourth sensor 34, and the fifth sensor 35 from the back to the front above the outer side of the lock body (the direction of the front of the vehicle as specified by the parking space is the front, and the rear direction is the rear). The parking detection sensor 3 can adopt commonly used commercially available sensors at present, and its working principle is a mature existing technology and will not be elaborated here.

[0022] Refer to Figures 3 to 5In this embodiment, the blocking arm driving mechanism 4 is used to drive the blocking arm 6 to move forward and backward (along the length direction of the lock body) in the blocking arm accommodating groove 11 of the lock body 1 to a position where it can be extended from the lock body 1 to lock the car, and to extend the 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 track 41-1 fixedly arranged along the length direction at the top of 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 track 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 matched with the screw rod 41-5, a lower track 41-7 fixedly connected to the screw rod nut 41-6, and load-bearing rollers 41-8 arranged on both sides of the lower track 41-7 and rollingly matched with the upper track 41-1. In this embodiment, two load-bearing rollers 41-8 are arranged on each side of the lower track 41-7. As a preferred embodiment, the travel drive assembly 41 also includes two limit wheels 41-9 disposed on both sides of the lower track 41-7 for limiting the two sides of the running direction of the lower track 41-7 to prevent deviation. The car-blocking arm telescopic drive assembly 42 includes a mounting connection frame 42-1 fixedly connected to the lower track 41-7 and a car-blocking arm electric push rod 42-2 fixedly arranged on the mounting connection frame 42-1; as a preferred embodiment, the mounting connection frame 42-1 and the lower track 41-7, as well as the car-blocking arm electric push rod 42-2 and the mounting connection frame 42-1 are fixedly connected by bolts to facilitate disassembly and assembly.

[0023] The car-blocking arm connection mechanism 5 is used for transmission connection between the car-blocking arm driving mechanism 4 and the car-blocking arm 6, so as to realize the extension and retraction of the car-blocking arm 6 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 connection 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 with the mounting connecting frame 42-1 of the car-blocking arm telescopic driving assembly 42 through the rotating shaft 52, and the push rod connecting pin 53 is transmission-connected with the car-blocking arm electric push rod 42-2 of the car-blocking arm telescopic driving assembly 42. During operation, through the retraction and extension movement of the car-blocking arm electric push rod 42-2, the rotating bracket 51 can be rotated inward and outward of the lock body 1 accordingly relative to the mounting connecting frame 42-1 of the car-blocking arm telescopic driving assembly 42 by relying on the rotating shaft 52. As a preferred embodiment, in this embodiment, the anti-rollover arm connection mechanism 5 further includes an anti-tilt bracket 54 fixedly mounted on the rotating bracket 51 and sleeved with the anti-rollover arm 6. Figure 10As shown, the anti-tilt bracket 54 includes a frame body 54-1, a protruding arm 54-2 is provided on each side of the upper part of the frame body 54-1, and two connecting ears 54-3 are 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 setting the anti-tilt bracket 54 is to solve the technical problem that the anti-tilt arm of similar road tooth locks in the prior art is easily pushed back into the lock body by malicious toll evaders and easily damages the related components of the anti-tilt arm. In this embodiment, after the anti-tilt bracket 54 is set, due to the hard blocking of the anti-tilt bracket 54, it is basically impossible for human power to push the anti-tilt arm 6 back into the lock body 1. The anti-tilt bracket 54 is made of spring steel, which takes advantage of its characteristics of considerable rigidity and self-recovery ability after deformation.

[0024] 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 arranged on the shell 61, a car-blocking frame 63 connected to the telescopic bracket 62, a car-blocking frame electric push rod 64 used to make the car-blocking frame 63 rise and retract through the transmission of the telescopic bracket 62, an up-and-down unloading component 65 used to unload the force when the upper part of the car-blocking frame 63 is subjected to force, and an anti-twisting component 66 used to prevent the car-blocking arm 6 from being deformed and damaged due to the forced passage of the wheel.

[0025] As a specific implementation method, the shell 61 is a structural member in the shape of a square tube as a whole, and the two side plates of the shell 61 along the length direction are respectively provided with corresponding first slide grooves 61-1 and second slide grooves 61-2; 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 with two crosses 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 connected to one end of a sliding shaft 62-2 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 connected to 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. As a preferred embodiment, the telescopic bracket 62 further includes a support reinforcement member 62-2-1 fixedly disposed in the housing 61 for assisting in supporting the movement of the sliding shaft 62-2 disposed on the housing 61, and the support reinforcement member 62-2-1 is a plate member that is overall U-shaped. The anti-vehicle frame electric push rod 64 is movably disposed in the housing 61, and the anti-vehicle frame electric push rod 64 is transmission-connected to the sliding shaft 62-2 disposed in the housing 61. When working, the anti-vehicle frame electric push rod 64 performs telescopic movement, and the anti-vehicle frame 63 is lifted and lowered to reset through the transmission of the telescopic bracket 62.

[0026] See also Figure 6 and Figure 7 The up-down unloading assembly 65 is arranged in the housing 61, and is used to unload the pressure from above the anti-vehicle frame 63 to prevent the anti-vehicle frame electric push rod 64 from being damaged by pressure and the anti-vehicle frame 63 from being too tight against the vehicle chassis and causing damage to the vehicle. As a specific implementation, in this embodiment, the up-down unloading assembly 65 includes two unloading springs 65-1, a first connecting rod 65-2 fixed on the anti-vehicle frame electric push rod 64, and a second connecting rod 65-3 fixed 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.

[0027] The working principle and process of the up-and-down force relief component 65 are as follows: When a force is applied above the vehicle blocking frame 63, both ends of the four support arms 62-1 rotate relative to the shafts they are connected to. At the same time, through the transmission of the telescopic bracket 62, the sliding shaft 62-2 provided in the housing 61 slides along the first chute 61-1 of the housing 61, driving the vehicle blocking frame electric push rod 64 to move. Through the first connecting rod 65-2 fixedly provided on the vehicle blocking frame electric push rod 64, the two force relief springs 65-1 are stretched, thereby achieving force relief. When the pressure above the vehicle blocking frame 63 is eliminated, the elastic reset of the two force relief springs 65-1 causes the vehicle blocking frame electric push rod 64 to reset.

[0028] See Figures 6 to 9 , the anti-twist component 66 is used to prevent the wheels from passing over the vehicle blocking arm 6 when a malicious toll-evading vehicle leaves the parking space, which may cause damage to the vehicle blocking arm 6. As a specific implementation method, in this embodiment, the anti-twist component 66 includes two anti-twist springs 66-1, a first connecting shaft 66-2, a second connecting shaft 66-3, two steel wire ropes 66-4, a moving slider 66-5, a fixed slider 66-6, and a connecting member 66-7. One side of the moving slider 66-5 is provided with a protrusion 66-5-1, and the moving slider 66-5 is provided with two rope-passing holes 66-5-2; the side of the fixed slider 66-6 opposite to the moving slider 66-5 is provided with a recess 66-6-1 whose shape matches the protrusion 66-5-1 of the moving slider 66-5, and the fixed slider 66-6 is provided with two rope-passing holes 66-6-2. The connecting member 66-7 is a U-shaped structural member, and the connecting member is also provided with two rope-passing holes. The fixed slider 66-6 is fixedly connected to the connecting member 66-7, and the connecting member 66-7 is fixedly connected to the rotating bracket 51 of the vehicle blocking arm connection mechanism 5. The first connecting shaft 66-2 is fixedly provided at a position slightly in the middle of the housing 61. One end of each of the two anti-twist springs 66-1 is connected to the first connecting shaft 66-2, and the other end of each of the two anti-twist 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-passing hole 66-5-2 of the moving slider 66-5, the rope-passing hole 66-6-2 of the fixed slider 66-6, and the rope-passing 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 closely attached to the connecting member 66-7, and one end of the housing 61 is fixedly connected to the moving slider 66-5.

[0029] The working principle and process of the anti-twist component 66 are as follows: When the blocking arm 6 is in the extended blocking state, if a vehicle that maliciously evades tolls directly impacts the blocking arm 6 and drives out, when the wheel impacts the housing 61 of the blocking arm 6, the moving slider 66-5 fixedly connected to the housing 61 rotates relative to the fixed slider 66-6 or even is pulled out of the fixed slider 66-6 and then rotates. At this time, the two anti-twist springs 66-1 are stretched to make up for the distance difference of the displacement deformation of the housing 61, so that the blocking arm 6 lies down in the direction of the wheel's advance, minimizing the damage to the blocking arm 6 when the wheel passes over the blocking arm 6 to the greatest extent. When the wheel has passed, the external force disappears, and under the action of the elastic restoring force of the two anti-twist springs 66-1, the blocking arm 6 automatically resets. The two anti-twist springs 66-1 are connected to the second connecting shaft 66-3 by two steel wires 66-4, taking advantage of the characteristics of the steel wires that can be twisted and bent, so as to achieve the function of the blocking arm 6 resisting the impact of the wheel passing over and self-resetting together with the two anti-twist springs 66-1.

[0030] See Figure 1 , the lighting component includes a solar panel 7 fixedly arranged on the lock body 1, a color light strip 71 arranged in the lock body 1 and above the blocking arm receiving groove 11, and a light strip controller (all three components are commercially available parts, and the working principle is a mature existing technology) that is arranged in the lock body 1 and is matched with the solar panel 7. During operation, the solar panel 7 provides power for the color light strip 71 through the light strip controller and controls the lighting and extinguishing of the color light strip 71. The time for the light strip controller to control the lighting and extinguishing of the color light strip 71 can be set according to specific circumstances. In this embodiment, the controller controls the lighting and extinguishing time of the color light strip 71 from 18:00 to 6:00 the next day. The solar panel 7, the light strip controller, and the color light strip 71 are set as a preferred method. In this embodiment, by setting the solar panel 7, the light strip controller, and the color light strip 71, the color light strip 71 is lit at night. On the one hand, it can significantly prompt the vehicle driver that there is a parking lock on the roadside of the parking space, which is conducive to the vehicle driver noticing the parking lock to standardize parking and payment. At the same time, the color light strips 71 of each parking lock arranged on the roadside also serve as landscape lights for road lighting and beautification. The lighting component set in this embodiment is generally not available in current similar roadside locks and is one of the innovative points of the intelligent roadside lock in this embodiment.

[0031] The main controller and the power supply module are arranged inside the lock body 1. The power supply module provides the power required for the operation of the intelligent curb lock in this embodiment. It is a mature existing technology and will not be elaborated here. The main controller serves as the overall control component of the intelligent curb lock in this embodiment, similar to existing similar parking space locks. Different from the prior art, when installed on the roadside parking spaces, the main controllers of two adjacent intelligent curb locks in this embodiment communicate with each other. It should be emphasized that the structure and working principle of the main controller itself, as well as the realization of mutual communication between the two main controllers, are all mature existing technologies and will not be elaborated here. However, the intelligent curb lock in this embodiment innovatively establishes a communication connection between the main controllers of two adjacent intelligent curb locks, enabling the two adjacent intelligent curb locks in this embodiment to cooperate with each other to effectively lock and charge malicious fare-evading vehicles parked in the middle of two adjacent parking spaces, which is a technology not possessed by similar curb parking space locks in the prior art. Each of the aforementioned parking detection sensors 3 is electrically connected to the main controller to send detection signals to the main controller. The traveling drive motor 41-2 of the traveling drive assembly 41 of the blocking arm drive mechanism 4, the blocking arm electric push rod 42-2 of the blocking arm telescopic drive assembly 42, and the blocking arm frame electric push rod 64 of the blocking arm 6 are all electrically connected to the main controller and controlled by the main controller to start and stop. This is also a mature existing technology and will not be elaborated here.

[0032] See Figure 11 and Figure 12 , the working principle and process of the intelligent curb lock in this embodiment to solve four technical problems commonly existing in existing similar curb locks through structural design are briefly described as follows: One intelligent curb lock in this embodiment is fixedly installed on each side of each roadside parking space close to the curb. As Figure 11 shown, after power-on, a communication connection is automatically established between the main controllers of two adjacent intelligent curb locks installed on the first parking space 100 and the second parking space 101. Figure 11The single arrow indicates the parking direction of the parking space. Taking the vehicle entering the first parking space 100 as an example, when the vehicle drives into the first parking space 100, first, the first sensor 31 sends a signal to the main controller of the intelligent curb lock on this parking space to inform that a vehicle has entered. When the vehicle is parked normally and standardly in the middle of the first parking space 100, the second sensor 32, the third sensor 33, and the fourth sensor 34 send signals 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 outwards from the blocking arm receiving groove 11 of the lock body 1 and then controls the blocking frame 63 to rise upwards to make soft contact with the chassis of the parked vehicle to achieve vehicle locking. In this embodiment, when the blocking frame 63 rises upwards to make soft contact with the chassis of the parked vehicle for locking, the control method is realized by the main controller monitoring the driving current of the blocking frame electric push rod 64 of the blocking arm 6. When the driving current of the blocking frame electric push rod 64 reaches the set threshold value, the main controller determines that reliable locking has been achieved, and the soft contact between the blocking frame 63 and the vehicle chassis is realized by the up and down force unloading component 65 and the rubber strip 63-2 on the blocking frame 63, so as to realize reliable locking of the parked vehicle. When the vehicle owner scans the code on the two-dimensional code nameplate 2, the main controller automatically sends the parking duration and the amount of fees to the background according to the method similar to the prior art, and the background then sends it to the vehicle owner's mobile phone. After the vehicle owner pays the fee, the main controller controls the blocking frame 63 of the blocking arm 6 to reset downwards and makes the blocking arm 6 reset to the blocking arm receiving groove 11 of the lock body 1 to realize unlocking of the parked vehicle about to leave. When the vehicle drives out of 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 and fee payment for this time are completed. Obviously, due to the different specific parking positions of the vehicle parked normally in the first parking space 100, when the blocking arm 6 cannot extend out normally, the main controller controls the blocking arm 6 to move a certain position back and forth and then unlocks and locks it.

[0033] A brief description of the technical solution for the intelligent curb lock in this embodiment to solve the first common technical problem existing in the existing similar curb locks is as follows: If a vehicle owner evades fees maliciously and parks the vehicle (especially a small car with a relatively short wheelbase) between the first parking space 100 and the second parking space 101, that is, straddling the parking space dividing line 103, it is difficult for the existing similar curb locks to lock and charge for this situation. The intelligent curb lock in this embodiment can effectively solve this problem. Specifically, when a parking person who evades fees maliciously parks across the parking space dividing line 103, the fifth sensor 35 of the intelligent curb lock on the side of the first parking space 100 sends a detection signal of detecting a vehicle entering to the main controller of this lock, and at the same time, the first sensor 31 of the intelligent curb lock on the side of the second parking space 101 sends a detection signal of detecting a vehicle entering to the main controller of this lock. After the adjacent two intelligent curb locks confirm the above detection information through interactive communication, it is determined that a vehicle parks maliciously across the parking space dividing line 103. At this time, if Figure 12As shown by the hollow arrow, the blocking arm 6 of the intelligent curb lock on the side of the first parking space 100 moves towards the rear of the parked vehicle, and the blocking arm 6 of the intelligent curb lock on the side of the second parking space 101 moves towards the front of the parked vehicle. There are three ways to lock the maliciously parked vehicle: First, the blocking arm 6 of the intelligent curb lock on the side of the first parking space 100 reliably locks the chassis at the rear of the maliciously parked vehicle; Second, the blocking arm 6 of the intelligent curb lock on the side of the second parking space 101 reliably locks the chassis at the front of the maliciously parked vehicle; Third, the two intelligent curb locks simultaneously and reliably lock the chassis at the rear and the chassis at the front of the maliciously parked vehicle. In this embodiment, the third locking method is preferably used to achieve locking and charging for the maliciously parked vehicle. The subsequent unlocking after payment is the same as described above and will not be elaborated. The description in this paragraph about using the cooperation of two adjacent intelligent curb locks to achieve reliable locking and charging for a vehicle parked across the parking space dividing line 103 to avoid malicious fare evasion is the core innovation point of the present invention to solve the technical problems that cannot be solved by the same type of curb locks in the prior art.

[0034] A brief description of the technical solution of the intelligent curb lock in this embodiment to solve the second common technical problem of the same type of existing curb locks is as follows: If a vehicle owner tries to evade tolls maliciously and deliberately uses the wheels to block the position where the blocking arm 6 of the intelligent curb lock in this embodiment is located when parking, in order to block the blocking arm 6 and prevent it from normally extending to lock and charge, the solution of the intelligent curb lock in this embodiment is: when the main controller of the intelligent curb lock in this embodiment detects that the driving current of the blocking arm electric push rod 42-2 of the blocking arm driving mechanism 4 reaches the 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 traveling driving component 41 of the blocking arm driving mechanism 4, and then tries to extend the blocking arm 6 again. If the blocking arm 6 still cannot be extended, continue to change the position of the blocking arm 6 until the blocking arm 6 can be smoothly extended to open and lock. Therefore, the intelligent curb lock in this embodiment can effectively solve the technical problem that the same type of existing curb locks in the prior art cannot extend and lock due to malicious fare evasion by deliberately using wheels to block the blocking arm of the existing curb lock when parking.

[0035] A brief description of the technical solution of the intelligent curb lock in this embodiment to solve the third common technical problem of the same type of existing curb locks is as follows: By arranging an anti-twist component 66 on the blocking arm, it is possible to minimize the damage to the blocking arm 6 caused by the wheel passing over the blocking arm 6 to the greatest extent when the blocking arm 6 is impacted by the wheel. The specific structure and principle are as described above and will not be elaborated here.

[0036] In addition, by arranging a lighting component, the intelligent curb lock in this embodiment can not only effectively solve the fourth common technical problem of the same type of existing curb locks, but also has the function of road lighting and beautification. Similarly, the specific structure and principle are as described above and will not be elaborated here. Example

[0037] See also Figures 13 to 15 The intelligent road tooth lock of this embodiment is the same as that of embodiment 1 in other aspects, except that: unlike embodiment 1, in which only one car-blocking arm 6 that can move along the length direction of the lock body 1 is provided, four sets of car-blocking arm connecting mechanisms 5 are fixedly provided in the car-blocking arm accommodating groove 11 of the lock body 1 along the length direction of the lock body (which is also the parking direction) to connect four car-blocking arms 6, numbered from number one to number four. Correspondingly, the car-blocking arm driving mechanism 4 only retains the car-blocking arm electric push rod 42-2 of the car-blocking arm telescopic driving assembly 42 and fixes the four car-blocking arm electric push rods 42-2 in the lock body 1. The four sets of car-blocking arm connecting mechanisms 5 are each fixedly connected to the lock body 1 by their rotating brackets 51, and each set of car-blocking arm connecting mechanisms 5 is respectively connected to a car-blocking arm electric push rod 42-2 in transmission.

[0038] Although the smart tooth lock of this embodiment is different from the smart tooth lock of embodiment 1 in structure, it can also realize all the functions of the smart tooth lock of embodiment 1, which are briefly described as follows: First, when the owner parks the vehicle normally, one of the two blocking arms 6 located in the middle will lock the parked vehicle according to the specific parking position; Second, when a car owner parks his vehicle across the parking space dividing line 103 for malicious evasion of 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 at the same time to lock the parked vehicle; Thirdly, when the car owner intentionally uses the wheel 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 the lock 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.

[0039] Fourthly, the functions of the anti-twisting and up-down force unloading 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.

[0040] The above embodiments are descriptions of specific implementation methods of the present invention rather than limitations of the present invention. Technical personnel in the relevant technical field 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.
