Description

Technical Field

[0001] This application relates to the field of parking lock technology, and more particularly to a curb lock. Background Technology

[0002] The payment system for roadside parking spaces has largely transitioned from traditional manual collection to the use of parking management devices. Among these, parking locks installed near or on the curb are the most widely used due to their ease of installation, small footprint, and lack of obstruction of traffic. However, current curb parking locks lack reinforcement to strengthen the barrier arm, allowing drivers to forcibly drive over the barrier arm to evade payment. This also damages the barrier arm, requiring frequent disassembly and replacement. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a curb lock.

[0004] This application provides a curb lock, comprising: A lock box is fixed to the curb of a side parking space. The lock box has a receiving cavity extending in a first direction and an opening communicating with the receiving cavity is provided on the side of the lock box opposite to the curb. A vehicle-stopping arm, one end of which is hinged to the lock box, is rotatable about the hinge point in a second direction, such that the vehicle-stopping arm extends out of the receiving cavity or retracts into the receiving cavity; wherein the vehicle-stopping arm has a retracted state in which it is housed in the receiving cavity and an extended state in which it extends out of the opening to lock the parked vehicle; and the second direction is perpendicular to the first direction. The driving mechanism includes a driving member fixed to the lock box, a movable block disposed in the receiving cavity, and at least one connecting strip. One end of the connecting strip is connected to the movable block, and the other end is connected to the vehicle blocking arm. The driving member is throttle connected to the movable block and is used to drive the movable block to reciprocate along the first direction, so as to drive the connecting strip to drive the vehicle blocking arm to switch between the retracted state and the extended state. When the vehicle blocking arm is in the extended state, an angle is formed between the connecting strip and the lock box.

[0005] In one embodiment, the included angle ranges from 30° to 45°.

[0006] In one embodiment, the driving component includes a driving source, a first transmission screw, and a first screw sleeve. The first transmission screw is rotatably disposed in the receiving cavity along the second direction, and one end of the first transmission screw is connected to the output end of the driving source. The first screw sleeve is slidably sleeved on the first transmission screw, and the moving block is fixedly connected to the first screw sleeve.

[0007] In one embodiment, the inner bottom surface and inner top surface of the receiving cavity are provided with slides extending along the first direction, and the moving block is provided with slide pins at both ends in the second direction. The slide pins extend at least partially into the slides and are connected to the bearings in the slides to enable the moving block to slide along the slides.

[0008] In one embodiment, the driving member includes an electric actuator disposed within the receiving cavity, and the power end of the electric actuator is capable of extending and retracting along the first direction, and the moving block is connected to the power end of the electric actuator.

[0009] In one embodiment, there are two connecting strips arranged side by side in a third direction, with one end of each connecting strip connected to the vehicle blocking arm and the other end extending into the receiving cavity and connected to the moving block; wherein the third direction, the first direction, and the second direction are perpendicular to each other.

[0010] In one embodiment, the vehicle-stopping arm includes a housing, a telescopic frame, a vehicle-stopping bracket, a sliding block, and a power component. One end of the housing is hinged to the lock box, and the end of the connecting strip away from the moving block is fixedly connected to the housing. The telescopic frame is mounted on the housing, and one end of the telescopic frame away from the housing is connected to the vehicle-stopping bracket, while the other end is drivenly connected to the sliding block. The sliding block is located inside the housing and is drivenly connected to the power component. The power component is used to drive the sliding block to reciprocate along the length direction of the housing, thereby driving the telescopic frame to raise and lower the vehicle-stopping bracket along the third direction.

[0011] In one embodiment, the power component includes a power source, a second transmission screw, and a second screw sleeve. The second transmission screw is rotatably disposed within the housing along the length of the housing, and one end of the second transmission screw passes through the housing and is connected to the output shaft of the power source. The power source is fixedly connected to one end of the housing. The second screw sleeve is slidably sleeved on the second transmission screw and connected to the end of the telescopic frame away from the vehicle blocking frame.

[0012] In one embodiment, the upper and lower surfaces of the end of the housing that is hinged to the lock box are provided with connecting posts, and the inner bottom and inner top surfaces of the receiving cavity are respectively provided with connecting holes. The connecting posts are rotatably disposed in the connecting holes so as to realize that the housing can rotate relative to the lock box about the axis of the connecting posts.

[0013] In one embodiment, the curb lock further includes a first sensor, two second sensors, a third sensor, and two cameras. The first sensor is located on the top of the curb block and is used to detect the locking status of the curb block and the vehicle chassis. The two second sensors are respectively located on opposite sides of the curb block. The third sensor and the two cameras are all located on the side of the lock box facing away from the curb. The two cameras are located at both ends of the opening and are used to monitor the status of the vehicle entering the parallel parking space. The third sensor is located inside one of the cameras and is used to sense that the vehicle has parked in the parallel parking space.

[0014] In one embodiment, the curb lock further includes a thermally insulated battery box and an energy storage battery. The lock box has a battery compartment, the thermally insulated battery box is installed in the battery compartment, and the energy storage battery is detachably installed into the thermally insulated battery box.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: (1) By cleverly using one end of the connecting strip to connect the car stop arm and the other end of the connecting strip to connect the moving block, the lock box, the connecting strip and the car stop arm form a closed triangular support structure when the car stop arm is extended. Thus, when the vehicle forcibly drives over the car stop arm of the curb lock, the car stop arm is not easily pushed open in one direction, which can effectively prevent the vehicle from violently pushing open the car stop arm to evade tolls. It can also significantly reduce the excessive shaking or deformation of the car stop arm due to impact, reduce fatigue damage caused by repeated impacts, and help extend the service life of the car stop arm.

[0016] (2) The method of using screw drive to control the extension or retraction of the blocking arm into the receiving cavity is more efficient than gear and rack, belt and other transmission methods. Screw drive has a smaller backlash, which can avoid the shaking of the moving block caused by the backlash, ensure that the blocking arm is more stable during the switching process, reduce wear on the inner wall of the lock box, and can also stop more accurately in the preset position, avoiding the problem of incomplete storage or insufficient extension due to displacement error.

[0024] The technical terms used in the embodiments of this application are explained and described below.

[0025] The drive source 211 refers to the component that provides power to drive the first transmission screw 212 to rotate. Specifically, it can be an electric drive source 211 such as a DC motor, servo motor, or stepper motor in the prior art.

[0027] Furthermore, the first direction X, the second direction Y, and the third direction Z, which are mutually perpendicular to each other, are defined in this application for the convenience of describing the relative positional relationship of the components. Specifically, the lock box 10 is used as a reference, wherein the first direction X is the length direction of the lock box 10 (refer to...). Figure 1 The X direction is the first direction, and the Y direction is the width direction of the lock box 10 (refer to the X direction). Figure 1 The Y direction in the middle), and the third direction Z is the height direction of lock box 10 (refer to the Y direction). Figure 1 (in the Z direction).

[0028] Example 1 Figure 1 This is a top view schematic diagram of the extended state of a curb lock according to this application; Figure 2 This is a structural schematic diagram of a curb lock in its extended state according to this application. Please refer to... Figure 1 and Figure 2 This application provides a curb lock, which includes a lock box 10, a retractable wheel stop arm 30 housed within the lock box 10, and a drive mechanism 20 for driving the wheel stop arm 30 to extend or retract from the lock box 10.

[0029] Specifically, the lock box 10 is a long strip-shaped structure fixed to the curb of the side parking space. The lock box 10 has a receiving cavity 10a extending along a first direction X, and an opening communicating with the receiving cavity 10a is provided on the side of the lock box 10 opposite to the curb. Since the lock box 10 is exposed to the elements for extended periods, it needs to resist natural corrosion and possess high mechanical strength to withstand external impacts and malicious damage. Therefore, the lock box 10 can be made of metal materials (such as 304 stainless steel, aluminum alloy, etc.) or composite materials (such as carbon fiber composite materials), with no limitation on the type.

[0030] For example, one end of the car-stopping arm 30 is hinged to the lock box 10, allowing it to rotate about the hinge point in the second direction Y, so that the car-stopping arm 30 extends out of the receiving cavity 10a or retracts into the receiving cavity 10a. The drive mechanism 20 includes a drive member 21 fixed to the lock box 10, a movable block 22 disposed in the receiving cavity 10a, and at least one connecting strip 23. One end of the connecting strip 23 is connected to the movable block 22, and the other end is connected to the car-stopping arm 30. The drive member 21 is tractively connected to the movable block 22, and is used to drive the movable block 22 to reciprocate along the first direction X, so as to drive the connecting strip 23 to switch the car-stopping arm 30 between the retracted state and the extended state. Here, it should be noted that the retracted state refers to the state in which the car-stopping arm 30 is retracted into the receiving cavity 10a, while the extended state refers to the state in which the car-stopping arm 30 extends out of the opening to lock the parked vehicle. When the car-stopping arm 30 is in the extended state, an angle is formed between the connecting strip 23 and the lock box 10.

[0031] In other words, when the vehicle is parked in a parallel parking space and the parking time exceeds the free time limit, the drive unit 21 is activated to drive the moving block 22 to move in the first direction X. Since one end of the moving block 22 is connected to the connecting strip 23, and the other end of the connecting strip 23 is connected to the blocking arm 30, and one end of the blocking arm 30 is hinged to the lock box 10, the moving block 22 can drive the connecting strip 23 to drive the blocking arm 30 to rotate around the hinge point in the second direction Y during the movement of the moving block 22. At this time, the blocking arm 30 extends out of the receiving cavity 10a and continuously moves away from the lock box 10. After extending to a position perpendicular to the lock box 10, the drive component 21 stops, causing the moving block 22 to stop moving, thus completing the operation of extending the vehicle blocking arm 30. After the vehicle owner completes the payment, the drive component 21 restarts to drive the moving block 22 to move in the opposite direction of the first direction X, thereby driving the connecting bar 23 to drive the vehicle blocking arm 30 to rotate in the opposite direction of the second direction Y around the hinge point. At this time, the vehicle blocking arm 30 continuously approaches the lock box 10. After the vehicle blocking arm 30 is completely retracted into the receiving cavity 10a, the drive component 21 stops, causing the moving block 22 to stop moving, thus completing the operation of retracting the vehicle blocking arm 30.

[0032] One end of the wheel stop arm 30 is hinged to the lock box 10 and connected to one end of the connecting strip 23. The other end of the connecting strip 23 is connected to the moving block 22. This forms a closed triangular support structure with the lock box 10, the connecting strip 23, and the wheel stop arm 30. When a vehicle drives over the extended wheel stop arm 30, the impact force is transmitted to the connecting strip 23 through the wheel stop arm 30. Due to the geometric stability of the triangular structure, the impact force can be dispersed to the lock box 10 and the moving block 22. The lock box 10 is fixed to the curb, and the moving block 22 is limited and cannot move freely. This makes it difficult for the wheel stop arm 30, which is hinged to the lock box 10, to be pushed open in one direction. This can effectively prevent vehicles from forcibly pushing open the wheel stop arm 30 to evade tolls. It can also significantly reduce the excessive shaking or deformation of the wheel stop arm 30 due to impact, reduce fatigue damage caused by repeated impacts, and help extend the service life of the wheel stop arm 30.

[0033] In practical applications, the angle range of the aforementioned included angle is 30°-45°. If the included angle is less than 30°, the connecting strip 23 and the lock box 10 are nearly parallel, and the impact force will be more converted into a pushing force on the moving block 22 along the first direction X, which may cause the moving block 22 to be pushed and displaced, weakening the support stability; if the included angle is greater than 45°, the impact force will be more converted into a shearing force on the connecting strip 23, causing the connection point between the connecting strip 23 and the moving block 22 or the vehicle blocking arm 30 to break. Therefore, in this embodiment, setting the included angle in the range of 30°-45° allows the impact force to be decomposed into a tensile force along the axial direction of the connecting strip 23 and a component force perpendicular to the connecting strip 23 through the connecting strip 23. The axial tensile force can be effectively borne by the locking force of the driving component 21 (such as the first transmission screw 212), while the vertical component force is dispersed through the lock box 10 fixed to the curb, avoiding overload of a single component, significantly improving the ability of the vehicle blocking arm 30 to resist violent impacts from vehicles, and mechanically preventing the toll evasion behavior of being forcibly pushed open.

[0034] Figure 3 This is a schematic diagram of the structure of a curb lock after removing the lock box, as described in this application. Please refer to... Figure 3 In one embodiment, the driving component 21 includes a driving source 211, a first transmission screw 212, and a first screw sleeve 213. The first transmission screw 212 is rotatably disposed in the receiving cavity 10a along the second direction Y, and one end of the first transmission screw 212 is connected to the output end of the driving source 211. The first screw sleeve 213 is slidably sleeved on the first transmission screw 212, and the moving block 22 is fixedly connected to the first screw sleeve 213.

[0035] When the brake arm 30 needs to be extended or retracted into the receiving cavity 10a, the drive source 211 drives the first transmission screw 212 to rotate. Since the first screw sleeve 213 is slidably mounted on the first transmission screw 212 through a threaded engagement, and the moving block 22 is fixedly connected to the first screw sleeve 213, the moving block 22 can be driven to reciprocate along the first direction X, thereby driving the connecting bar 23 to drive the brake arm 30 to rotate around its hinge point along the second direction Y, thus controlling the switch between the retracted and extended states of the brake arm 30. In other words, this embodiment uses screw drive to control the extension or retraction of the brake arm 30 into the receiving cavity 10a. Compared with gear rack, belt, and other transmission methods, screw drive has a smaller backlash, which can avoid the shaking of the moving block 22 caused by the backlash, ensuring that the brake arm 30 is more stable during the switching process, reducing wear and tear on the inner wall of the lock box 10, and also stopping more accurately in the preset position, avoiding problems such as incomplete retraction or insufficient extension due to displacement errors.

[0036] Furthermore, if a vehicle forcibly impacts the blocking arm 30, the impact force will be transmitted to a certain block through the connecting bar 23, thereby generating a thrust in the first direction X on the first lead screw sleeve 213. However, since the lead screw transmission has a self-locking property, this thrust cannot drive the first transmission lead screw 212 to rotate in the opposite direction, thereby rigidly locking the position of the moving block 22. Thus, the supporting force of the connecting bar 23 firmly limits the extension position of the blocking arm 30, preventing the blocking arm 30 from being violently pushed open.

[0037] In practical applications, when the vehicle blocking arm 30 is impacted by a vehicle, the impact force is transmitted to the moving block 22 through the connecting strip 23, causing the moving block 22 to wobble (i.e., rotate or tilt around the axis of the first transmission screw 212). This results in the vehicle blocking arm 30 not extending fully and thus failing to effectively block the vehicle, or failing to fully retract into the receiving cavity 10a and becoming exposed and vulnerable to collision. To address this, in one embodiment, the inner bottom surface and inner top surface of the receiving cavity 10a are provided with a slide rail 50 extending along the first direction X. The moving block 22 has sliding posts 70 at both ends in the second direction Y. The sliding posts 70 extend at least partially into the slide rail 50 and connect with a bearing (not shown) inside the slide rail 50, so as to enable the moving block 22 to slide along the slide rail 50. In other words, by providing a sliding column 70 on the movable block 22 in cooperation with a slide rail 50 extending along the first direction X, the slide rail 50 always limits the movable block 22 when it is driven to move along the first direction X, ensuring that the movable block 22 moves stably and accurately along the first direction X without deviation or wobbling, thereby accurately stopping the blocking arm 30 in the preset position. Furthermore, by providing a bearing within the slide rail 50 and connecting it to the sliding column 70, the sliding of the movable block 22 is ensured to be smoother.

[0038] In one embodiment, two connecting bars 23 are provided, arranged side by side in the third direction Z. One end of each connecting bar 23 is connected to the vehicle blocking arm 30, and the other end extends into the receiving cavity 10a and is connected to the moving block 22. That is, the two connecting bars 23 arranged side by side in the third direction Z are connected to the vehicle blocking arm 30 and the moving block 22 respectively, forming two symmetrical triangular support structures. This improves the overall bending stiffness, effectively resists deformation caused by impact, ensures that the vehicle blocking arm 30 is not pushed away, and thus prevents malicious fare evasion.

[0039] Figure 4 This is a schematic diagram of the curb lock's center-damping arm 30 after removing the housing 32. Please refer to... Figure 4 In one embodiment, the vehicle blocking arm 30 includes a housing 32, a telescopic frame 33, a vehicle blocking frame 34, a sliding block 35, and a power component 31. One end of the housing 32 is hinged to the lock box 10, and the end of the connecting strip 23 away from the moving block 22 is fixedly connected to the housing 32. The telescopic frame 33 is disposed on the housing 32, and one end of the telescopic frame 33 away from the housing 32 is connected to the vehicle blocking frame 34, and the other end is drivenly connected to the sliding block 35. The sliding block 35 is disposed inside the housing 32 and is drivenly connected to the power component 31. The power component 31 is used to drive the sliding block 35 to reciprocate along the length direction of the housing 32, so as to drive the telescopic frame 33 to drive the vehicle blocking frame 34 to rise and fall along the third direction Z.

[0040] In other words, when the vehicle is parked in a parallel parking space and the parking time exceeds the free time limit, the drive unit 21 drives the moving block 22 to move along the first direction X, so that the connecting strip 23 drives the housing 32 to rotate around the hinge point along the second direction Y, so that the housing 32 extends out of the receiving cavity 10a and moves away from the lock box 10. When the housing 32 extends to a position perpendicular to the lock box 10, the drive unit 21 stops, so that the moving block 22 stops moving. At this time, the entire extended blocking arm 30 is located under the chassis of the vehicle. Then, the power unit 31 is activated to drive the sliding block 35 to move along the length direction of the housing 32, so that the telescopic frame 33 on the housing 32 drives the blocking frame 34 to rise along the third direction Z, so that the blocking frame 34 moves closer to the parking space. The vehicle's chassis is locked once the parking arm 34 comes into contact with the chassis of the parked vehicle. After the owner completes payment, the power unit 31 is activated to drive the sliding block 35 to move in the opposite direction along the length of the housing 32, thereby driving the telescopic frame 33 to lower the parking arm 34 in the third direction Z, so that the parking arm 34 is released from the lock on the chassis of the parked vehicle. Then, the drive unit 21 is activated to drive the moving block 22 to move in the opposite direction X, thereby driving the connecting bar 23 to drive the housing 32 to rotate in the opposite direction Y around the hinge point. At this time, the housing 32 continuously approaches the lock box 10. After the entire parking arm 30 is completely retracted into the receiving cavity 10a, the drive unit 21 stops, causing the moving block 22 to stop moving, thus completing the operation of retracting the parking arm 30.

[0041] It should be noted that a QR code nameplate is fixed on the upper side of the lock box 10. This QR code nameplate is used for car owners to scan and pay when leaving the parking space. Since QR code scanning technology is mature and existing, it will not be elaborated on.

[0042] Furthermore, when the parking brake 34 is raised to lock the chassis of the parked vehicle, it is necessary to promptly determine whether the parking brake 34 is in contact with the vehicle chassis to avoid a false lock scenario where the parking brake arm 30 extends but fails to effectively engage with the vehicle chassis, allowing the driver to easily drive away and evade payment; or where excessive tightening of the parking brake 34 and the vehicle chassis causes wear and tear on both components (such as deformation of the parking brake 34 or scratches on the paint of the vehicle chassis). Therefore, the parking brake 34 is equipped with a first sensor 40, which is used to detect the locking status of the parking brake 34 and the vehicle chassis. It should be noted that using sensors to check whether the parking brake arm 30 is locked to the vehicle chassis is existing technology and will not be elaborated upon further.

[0043] In addition, two second sensors 100 are provided on opposite sides of the parking brake 34 to monitor whether there are obstacles during the extension or retraction of the parking brake arm 30, thereby ensuring the smooth extension or retraction of the parking brake arm 30. For example, when the parking brake arm 30 extends from the receiving cavity, a second sensor 100 located outside the receiving cavity 10a will monitor the situation in the parking space. If the parking is not in accordance with regulations or someone is standing in its extension path, the parking brake arm 30 will be controlled to pause its extension and a prompt will be issued. After the vehicle is properly parked in the parking space or the person standing has left, the parking brake arm 30 will continue to extend. Similarly, when the parking brake arm 30 retracts into the receiving cavity 10a, a second sensor 100 located near the lock box 10 will monitor whether there are obstacles in the retraction path of the parking brake arm 30. The parking brake arm 30 will continue to retract into the receiving cavity only after the obstacles have disappeared.

[0044] The power component 31 includes a power source 311, a second transmission screw 312, and a second screw sleeve 313. The second transmission screw 312 is rotatably disposed inside the housing 32 along the length of the housing 32, and one end of the second transmission screw 312 passes through the housing 32 and is connected to the output shaft of the power source 311. The power source 311 is fixedly connected to one end of the housing 32. The second screw sleeve 313 is slidably sleeved on the second transmission screw 312 and is connected to the end of the telescopic frame 33 away from the vehicle blocking frame 34.

[0045] In one embodiment, the upper and lower surfaces of the end of the housing 32 that is hinged to the lock box 10 are provided with connecting posts 80, and the inner bottom and inner top surfaces of the receiving cavity 10a are respectively provided with connecting holes. The connecting posts 80 are rotatably disposed in the connecting holes to enable the housing 32 to rotate relative to the lock box 10 about the axis of the connecting posts 80. In this way, the gap between the housing 32 and the receiving cavity 10a can be ensured to be uniform, avoiding friction between the housing 32 and the cavity wall or jamming between the connecting posts 80 and the connecting holes caused by swaying. This ensures smooth operation of the vehicle blocking arm 30 when switching between the retracted and extended states, and reduces mechanical wear.

[0046] In one embodiment, the curb lock also includes two cameras 60 and a third sensor 90 located on the side of the lock housing 10 facing away from the curb. The two cameras 60 are located at opposite ends of the opening to monitor the status of a vehicle parked in the parallel parking space. The third sensor 90 is located inside one of the cameras 60 to sense that a vehicle has entered the parallel parking space. In practical applications, when the two third sensors 90 detect a vehicle signal, it indicates that a vehicle has entered the parking space. At this time, the two cameras 60 are activated to photograph the entering vehicle. The parking time is then calculated. Only after the parking time exceeds the free time will the vehicle-locking arm 30 be extended to lock the vehicle.

[0047] To control the start and stop of the drive mechanism, a controller (not shown) and an energy storage battery (not shown) are installed. The energy storage battery supplies power to the controller, power source 311, drive source 211, light strips, and other electrical equipment. In practical applications, the energy storage battery is housed in the lock box 10. However, due to the high surface temperature under sunlight, the lock box 10, which is fixed to the curb of the side parking space, is in direct contact with the ground. This causes the ground heat to be conducted to the lock box 10, placing the energy storage battery inside the lock box 10 at a high temperature. This high temperature accelerates the internal chemical reaction of the battery, leading to a rapid decrease in capacity and potentially causing battery bulging, leakage, or even short circuits and fires.

[0048] Figure 5 This is a schematic diagram of the structure of one embodiment of a curb lock according to this application; Figure 6 This is a schematic diagram of the heat-insulating battery box and lock box in a curb lock according to this application. Please refer to [the diagram for reference]. Figure 5 and Figure 6In one embodiment, the curb lock further includes a heat-insulated battery box 110. The lock box 10 has a battery compartment 10b, and the heat-insulated battery box 110 is installed inside the battery compartment 10b. The energy storage battery is detachably installed inside the heat-insulated battery box 110. That is, by setting a heat-insulated battery box 110 inside the battery compartment 10b of the lock box 10, the heat-insulating performance of the heat-insulated battery box 110 itself prevents the transfer of high temperatures from the outside of the lock box 10 to the inside, thereby maintaining the temperature within the optimal operating range of the battery (20-45℃) and avoiding damage to the energy storage battery from high temperatures. It should be noted that the heat-insulated battery box 110 can be made of polyurethane foam material, but is not limited to this.

[0049] For example, the energy storage battery is installed in the heat-insulated battery box 110 in a detachable manner, so that when the battery fails or the power is exhausted, there is no need to remove the lock box 10 of the curb lock. Simply open the battery compartment 10b to open the heat-insulated battery box 110, take out the energy storage battery from the heat-insulated battery box 110, and then put the new energy storage battery into the heat-insulated battery box 110 to quickly complete the battery replacement operation. No professional tools and complicated disassembly steps are required, which greatly shortens the maintenance time.

[0050] Furthermore, the energy storage battery can be a solar cell, and a solar panel is fixed to the upper surface of the lock box 10. The solar panel absorbs solar energy, converts it into electrical energy, and stores it in the solar cell, thereby powering the controller, power source 311, drive source 211, light strip, and other electrical equipment installed on the lock box 10. It should be noted that the technology of converting solar energy into electrical energy using solar panels and storing it in solar cells is a mature existing technology, and will not be elaborated upon further.

[0051] Example 2 The difference between Example 2 and Example 1 is that the specific structures of the driving component and the power component are different. Figure 7 This is a structural schematic diagram of a curb lock embodiment 2 of this application. (Refer to...) Figure 7 Specifically, in this embodiment, both the driving component and the power component are electric actuators. For ease of description, the two electric actuators will be referred to as the first electric actuator and the second electric actuator, respectively.

[0052] The driving component includes a first electric actuator 120, which is disposed in the receiving cavity 10a. The power end of the first electric actuator 120 can extend and retract along the first direction Y. The moving block 22 is connected to the power end of the electric actuator 120.

[0053] The power component includes a second electric actuator 130, which is located inside the housing 32. The power end of the second electric actuator 130 can extend and retract along the length of the housing 32. The end of the telescopic frame 33 away from the vehicle blocking frame 34 is connected to the power end of the second electric actuator 130.

[0054] In summary, the curb lock provided in this application has the following effective effects: (1) By cleverly using one end of the connecting strip 23 to connect the car blocking arm 30 and the other end of the connecting strip 23 to connect the moving block 22, the lock box 10, the connecting strip 23 and the car blocking arm 30 form a closed triangular support structure when the car blocking arm 30 is extended. Thus, when the vehicle forcibly drives over the car blocking arm 30 of the curb lock, the car blocking arm 30 is not easily pushed open in one direction, which can effectively prevent the vehicle from forcibly pushing open the car blocking arm 30 to evade tolls. It can also significantly reduce the excessive shaking or deformation of the car blocking arm 30 due to impact, reduce fatigue damage caused by repeated impacts, and help extend the service life of the car blocking arm 30.

[0055] (2) The method of using screw drive to control the extension or retraction of the blocking arm 30 into the receiving cavity 10a is more efficient than gear and rack, belt and other transmission methods. Screw drive has a smaller backlash, which can prevent the moving block 22 from shaking due to the backlash. This ensures that the blocking arm 30 is more stable during the switching process, reduces wear on the inner wall of the lock box 10, and can also stop more accurately in the preset position, avoiding problems such as incomplete storage or insufficient extension due to displacement error.

[0056] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
