Description

Technical Field

[0001] This invention relates to the field of intelligent transportation Internet of Things technology, specifically to a guidance device for a smart parking system. Background Technology

[0002] Existing devices typically rely solely on IoT platforms or mobile apps to transmit parking space status information to drivers. Drivers need to look down at their phones or wait for the guidance screen to refresh to find out if a parking space is available. They cannot visually assess parking space occupancy from a distance, causing vehicles to still need to cruise slowly in the lanes to find an empty space. This increases congestion within the parking lot, prolongs parking time, and reduces parking efficiency.

[0003] Patent publication number CN220627225U includes: a guide panel screen, a buzzer indicator light, a parking space display, a parking space frame, a vehicle body, a dual-position sensor, a computer, a main controller, and a sub-node controller. The buzzer indicator light is electrically connected to the sub-node controller via wires, and the guide panel screen is electrically connected to the buzzer indicator light via wires. This utility model realizes efficient parking guidance by using a buzzer indicator light in conjunction with a dual-position sensor, and by using a buried sensor and an infrared phototube in conjunction with the red and green lights of the buzzer ball light body. The green light indicates an empty parking space, and the red light indicates a parked space, making it convenient for drivers to drive into the parking lot independently. In addition, the guide panel screen on the entrance gate and the parking space display in the parking lot will also electronically display the number of parking spaces, making it convenient for drivers to find and efficiently and quickly check the parking space guidance system.

[0004] Existing systems typically rely solely on IoT platforms or mobile apps to transmit parking space status information to drivers. Drivers need to look down at their phones or wait for the guidance screen to refresh to find out if a parking space is available, making it impossible to visually assess occupancy from a distance. This forces vehicles to continue slowly searching for vacant spaces within the aisles, increasing congestion, extending parking time, and reducing parking efficiency. Furthermore, the lighting equipment in existing systems usually operates in a constant-on mode, maintaining the same brightness regardless of whether a parking space is occupied. This fails to convey parking space status information through brightness variations and results in significant energy waste. The lighting fixtures operate at full capacity for extended periods, drastically shortening their lifespan and increasing operation and maintenance costs. In low-light conditions or at night, the sensors struggle to clearly capture license plate information, often resulting in recognition failures or errors. This prevents vehicles from entering or leaving the parking lot, causing congestion at entrances and exits and sometimes requiring manual intervention. This reduces the effectiveness of the guidance system and decreases the parking lot's throughput. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a guidance device for a smart parking system, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A guidance device for a smart parking system includes a parking lot, a canopy installed on the surface of the parking lot, a sensor head that monitors parked vehicles and uploads the data to the Internet of Things, a lighting device that provides illumination when parking, and a barrier plate that blocks vehicles. The lighting device is installed on the outer wall of the parking lot, the sensor head is installed on the inner wall of the parking lot, and the barrier plate slides on the inner wall of the parking lot. The guidance device for the smart parking system further includes: a barrier device for restricting the movement of vehicles, a control device for reducing the brightness of the lighting after a vehicle is parked in the parking space, and a protective device for blocking the wheels after a vehicle is parked in the parking space. The blocking device includes a sliding pressure plate that slides on the inner wall of the parking lot, a rotating roller that is rotatably connected to the inner wall of the blocking plate, a rotating plate that is rotatably connected to the parking lot, a pressure block that is fixedly connected to the blocking plate, and a limiting plate that slides on the inner wall of the rotating plate. The rotating plate has a groove on the side near the pressure block, and the limiting plate contacts the inner wall of the groove. The parking lot has a slot on the side near the limiting plate.

[0007] The blocking device also includes a rotating top plate rotatably connected to the parking lot, a rotating rod fixedly connected to the rotating top plate, a pressure rod fixedly connected to the blocking plate, and a stop rod for rotating the rotating top plate. The pressure rod is movably connected to the rotating rod. When the limiting plate is inserted into the slot, it strengthens the rigidity of the blocking plate. The rotating top plate further strengthens the strength of the blocking plate, enabling it to withstand stronger impact forces and ensuring that the blocking plate remains stable when subjected to impact.

[0008] A torsion spring is provided between the rotating plate and the parking area. The torsion spring is provided to drive the rotating plate to rotate in the direction of the blocking plate. An elastic element is provided between the blocking plate and the parking area. The elastic element is provided to drive the blocking plate to reset. The side of the limiting plate near the pressure block is set as an inclined surface. The limiting plate is set as an inclined surface to facilitate pressing the pressure block to move downward.

[0009] The control device includes a pull rod fixedly connected to the sliding pressure plate, a rotating rod rotatably connected to the parking lot, a pull plate slidably connected to the parking lot, and a shielding plate fixedly connected to the pull plate. One end of the rotating rod is movably connected to the pull rod, and the other end of the rotating rod is movably connected to the pull plate. After the vehicle parks, the shielding plate partially blocks the lighting device, reducing the brightness of the parking space lighting. By controlling the brightness, vehicles behind can be guided, allowing drivers of vehicles approaching from behind to judge the occupancy status of the parking space without having to get close, thus reducing the time spent searching for a parking space at low speed.

[0010] The control device also includes a rotating ring that rotates on the outer wall of the detector head, a connecting rod that rotates the rotating ring and the baffle plate, a pulling rod that slides on the inner wall of the parking lot, a rotating rod that rotates on the inner wall of the parking lot, and a lighting lamp that rotates on the inner wall of the parking lot. One end of the pulling rod is fixedly connected to the baffle plate. The rotation of the rotating ring drives the cleaning rod to move, clean the surface of the detector head, keep the detector head lens clean, ensure the accuracy of license plate recognition and vehicle monitoring, and avoid missed detections and false detections caused by dirt.

[0011] The rotating ring surface is provided with a cleaning rod, the other end of the pulling rod is movably connected to the rotating rod, and the rotating rod is fixedly connected to the lighting lamp.

[0012] The protective device includes a motor fixedly connected to the parking lot, a fixed rod fixedly connected to the output end of the motor, an inner rod sliding on the inner wall of the fixed rod, a push block fixedly connected to the inner rod, and a sliding rod fixedly connected to the pull plate. The outer wall of the fixed rod is provided with a sliding groove, and the push block contacts the inner wall of the sliding groove.

[0013] The protective device also includes a limiting rod fixedly connected to the sliding rod, a rotating baffle rotatably connected to the inner wall of the parking lot, a sliding push plate rotatably connected to the inner wall of the parking lot, and a connecting rod rotatably connecting the sliding push plate and the rotating baffle. The rotating baffle has a deep groove on the side near the inner rod and a shallow groove on the side near the inner rod. The inner rod has a round rod on the side near the rotating baffle. The round rod is spherical. When the rotating baffle rotates, the round rod rubs against the shallow groove, reducing the rotation speed of the rotating baffle and making the blocking action complete slowly and gradually, avoiding impact damage to the vehicle chassis or tires.

[0014] The push block has an inclined surface on the side near the sliding rod to facilitate the movement of the sliding rod. An elastic element is provided between the inner rod and the fixed rod to move the inner rod away from the fixed rod. An elastic element is also provided between the sliding push plate and the parking area to move the sliding push plate towards the rotating baffle. When the vehicle needs to leave, the motor is started via IoT control, which rotates the fixed rod and drives the rotating baffle to rotate back to its original position via the inner rod. Managers or vehicle owners can remotely control the baffle to reset via the IoT platform, eliminating the need for manual on-site operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, after the limiting plate is inserted into the slot, the rigidity of the blocking plate is strengthened. The rotating top plate further strengthens the strength of the blocking plate, enabling it to withstand stronger impact forces and ensuring that the blocking plate remains stable when subjected to impact. When the vehicle is parked, it first contacts the sliding pressure plate, generating a certain vibration to remind the driver that it is close to the parking limit position and avoids direct impact on the blocking plate due to reversing too fast. The contact between the wheels and the rotating roller can reduce the damage to the vehicle tires and parking equipment caused by impact and friction.

[0016] 2. In this invention, after a vehicle parks, the barrier partially obstructs the lighting device, reducing the brightness of the parking space lighting. This allows for guidance of vehicles behind by controlling the brightness, enabling drivers of approaching vehicles to determine the occupancy status of the parking space without needing to approach, reducing the time spent searching for a space at low speeds. The lighting automatically shuts off after the barrier is in place, avoiding unnecessary energy waste and extending the lifespan of the lighting device. The rotating ring moves the cleaning rod to clean the surface of the detector head, keeping the detector lens clean and ensuring the accuracy of license plate recognition and vehicle monitoring. This prevents missed or false detections due to dirt. The lighting lamp rotates away from the parking lot, illuminating the front of the vehicle. In nighttime or low-light conditions, it provides sufficient supplementary lighting for the license plate. The supplementary lighting from the detector head and the lighting lamp ensures the data quality of license plate recognition and vehicle monitoring, which is crucial for IoT monitoring.

[0017] 3. In this invention, when the rotating baffle rotates, the round rod and the shallow groove generate friction, reducing the rotation speed of the rotating baffle and making the blocking action complete slowly and gradually, avoiding impact damage to the vehicle chassis or tires. The rotating baffle and the blocking plate together block the wheel, forming front and rear clamping or double-sided limiting, enhancing the blocking effect. After the rotating baffle is fully rotated out, the round rod contacts the inside of the deep groove, finally locking the rotating baffle and preventing the baffle from retracting due to vehicle impact. When the vehicle needs to leave, the motor is started through the Internet of Things control, driving the fixed rod to rotate, which in turn drives the rotating baffle to rotate back to its original position through the inner rod. Managers or vehicle owners can remotely control the baffle to reset through the Internet of Things platform, without the need for manual on-site operation. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 One embodiment of the present invention includes a parking lot 1, a canopy 2 set on the surface of the parking lot 1, a detector 3 for monitoring parked vehicles and uploading data to the Internet of Things, a lighting device 4 for illuminating the parking area, and a barrier 5 for blocking vehicles. The lighting device 4 is set on the outer wall of the parking lot 1, the detector 3 is set on the inner wall of the parking lot 1, and the barrier 5 slides on the inner wall of the parking lot 1. The intelligent parking system guidance device also includes a barrier device for restricting the movement of vehicles, a control device for reducing the brightness of the lighting after a vehicle is parked in the parking space, and a protection device for blocking the wheels after a vehicle is parked in the parking space. The blocking device includes a sliding pressure plate 6 that slides on the inner wall of the parking lot 1, a rotating roller 7 that is rotatably connected to the inner wall of the blocking plate 5, a rotating plate 8 that is rotatably connected to the parking lot 1, a pressure block 9 that is fixedly connected to the blocking plate 5, and a limiting plate 10 that slides on the inner wall of the rotating plate 8. A groove is provided on the side of the rotating plate 8 near the pressure block 9, and the limiting plate 10 contacts the inner wall of the groove. A slot is provided on the side of the parking lot 1 near the limiting plate 10.

[0022] The blocking device also includes a rotating top plate 13 rotatably connected to the parking lot 1, a rotating rod 12 fixedly connected to the rotating top plate 13, a pressure rod 11 fixedly connected to the blocking plate 5, and a stop rod 14 that rotates the rotating top plate 13. The pressure rod 11 is movably connected to the rotating rod 12.

[0023] A torsion spring is provided between the rotating plate 8 and the parking lot 1. The torsion spring is provided to drive the rotating plate 8 to rotate in the direction of the blocking plate 5. An elastic element is provided between the blocking plate 5 and the parking lot 1. The elastic element is provided to drive the blocking plate 5 to reset. The side of the limiting plate 10 near the pressure block 9 is set as an inclined surface. The limiting plate 10 is set as an inclined surface to facilitate pressing the pressure block 9 to move downward.

[0024] In this embodiment, when a vehicle needs to be parked in parking lot 1, the detector 3 monitors the information of the parked vehicle and transmits it to the Internet of Things (IoT), allowing staff to see the usage status of each parking lot 1. When a vehicle parks in parking lot 1, its rear wheels will contact the barrier plate 5, which will block the rear wheels and prevent them from moving further. When the vehicle parks, it will first contact the sliding pressure plate 6, which will cause the vehicle to vibrate to remind the driver that it is about to park. When the wheel passes over the sliding pressure plate 6, the sliding pressure plate 6 will move downwards. The movement of the sliding pressure plate 6 will drive the barrier plate 5 to move, which in turn will drive the rotating roller 7 to move. When the vehicle continues to move, it will contact the rotating roller 7. If the wheel continues to move backwards, the rotating roller 7 will rotate with the rotation of the rear wheel, allowing the vehicle to safely pass outside the parking lot 1. When the barrier plate 5 moves downwards, it will drive the pressure block 9 to move, which will release the obstruction of the rotating plate 8. When the position of the pressure block 9 coincides with the slide groove, the rotating plate 8 will drive the limiting plate 10 to rotate in the direction of the pressure block 9. The pressure block 9 will contact the inner wall of the slide groove, and the contact between the pressure block 9 and the inner wall of the slide groove will contact the inclined surface of the limiting plate 10. The pressure block 9 will push the limiting plate 10 to move downward. The downward movement of the limiting plate 10 will insert into the slot to strengthen the rigidity of the blocking plate 5. The downward movement of the blocking plate 5 will drive the pressure rod 11 to move. The movement of the pressure rod 11 will press the rotating rod 12 to move. The movement of the rotating rod 12 will drive the rotating top plate 13 to rotate in the direction of the blocking plate 5. The rotating top plate 13 will strengthen the strength of the blocking plate 5, so that the blocking plate 5 can withstand stronger impact. When the limiting plate 10 is inserted into the slot, it strengthens the rigidity of the blocking plate 5. The rotating top plate 13 further strengthens the strength of the blocking plate 5, so that it can withstand stronger impact, ensuring that the blocking plate 5 remains stable when subjected to impact. When the vehicle is parked, it will first contact the sliding pressure plate 6, generating a certain vibration to remind the driver that it is close to the parking limit position and avoid directly hitting the blocking plate 5 due to reversing too fast. The contact between the wheel and the rotating roller 7 can reduce the damage to the vehicle tires and parking equipment caused by impact and friction.

[0025] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the control device includes a pull rod 21 fixedly connected to the sliding pressure plate 6, a rotating rod 22 rotatably connected to the parking lot 1, a pull plate 23 slidably connected to the parking lot 1, and a shielding plate 24 fixedly connected to the pull plate 23. One end of the rotating rod 22 is movably connected to the pull rod 21, and the other end of the rotating rod 22 is movably connected to the pull plate 23.

[0026] The control device also includes a rotating ring 26 that rotates on the outer wall of the detector head 3, a connecting rod 25 that rotates the rotating ring 26 and the shield 24, a pulling rod 27 that slides on the inner wall of the parking lot 1, a rotating rod 28 that rotates on the inner wall of the parking lot 1, and a lighting lamp 29 that rotates on the inner wall of the parking lot 1. One end of the pulling rod 27 is fixedly connected to the shield 24.

[0027] The surface of the rotating ring 26 is provided with a cleaning rod, and the other end of the pulling rod 27 is movably connected to the rotating rod 28. The rotating rod 28 is fixedly connected to the lighting lamp 29.

[0028] The protection device includes a motor 31 fixedly connected to the parking lot 1, a fixed rod 32 fixedly connected to the output end of the motor 31, an inner rod 33 sliding on the inner wall of the fixed rod 32, a push block 35 fixedly connected to the inner rod 33, and a sliding rod 34 fixedly connected to the pull plate 23. The outer wall of the fixed rod 32 is provided with a sliding groove, and the push block 35 contacts the inner wall of the sliding groove.

[0029] The protective device also includes a limiting rod 36 fixedly connected to the sliding rod 34, a rotating baffle 37 rotatably connected to the inner wall of the parking lot 1, a sliding push plate 38 rotatably connected to the inner wall of the parking lot 1, and a connecting rod 39 rotatably connecting the sliding push plate 38 and the rotating baffle 37. The rotating baffle 37 has a deep groove on the side near the inner rod 33 and a shallow groove on the side near the inner rod 33. The inner rod 33 has a round rod on the side near the rotating baffle 37, and the round rod is spherical in shape.

[0030] The push block 35 is inclined on the side near the sliding rod 34. The push block 35 is inclined to facilitate the movement of the sliding rod 34. An elastic element is provided between the inner rod 33 and the fixed rod 32. The elastic element is provided to drive the inner rod 33 to move away from the fixed rod 32. An elastic element is provided between the sliding push plate 38 and the parking lot 1. The elastic element is provided to drive the sliding push plate 38 to move in the direction of the rotating baffle 37.

[0031] In this embodiment, when the sliding pressure plate 6 moves downward, it drives the pull rod 21 to move. The movement of the pull rod 21 causes the rotating rod 22 to rotate. The rotation of the rotating rod 22 pulls the pull plate 23 to move. The movement of the pull plate 23 causes the blocking plate 24 to move. The movement of the blocking plate 24 blocks the lighting device 4, reducing the lighting provided by the parking space itself after the vehicle is parked. This allows vehicles approaching from behind to determine whether a vehicle is parked in the parking space by observing the brightness of the space. When the blocking plate 24 moves, it drives the connecting rod 25 to move. The movement of the connecting rod 25 causes the rotating ring 26 to rotate. The rotation of the rotating ring 26 causes the cleaning rod to move. The movement of the cleaning rod cleans the surface of the detector head 3. The movement of the blocking plate 24 causes the pull rod 27 to move. The movement of the pull rod 27 causes the rotating rod 28 to rotate. The rotation of the rotating rod 28 causes the lighting lamp 29 to rotate away from the parking lot 1. After the lighting lamp 29 rotates, it illuminates the front of the vehicle. To ensure drivers can clearly see license plates, after a vehicle parks, the shield 24 partially obstructs the lighting device 4, reducing the brightness of the parking space lighting. This allows for guidance of vehicles behind by controlling the brightness, enabling drivers of vehicles approaching from behind to determine the occupancy status of the parking space without having to approach, reducing the time spent searching for a parking space at low speeds. The lighting automatically turns off after the shield 24 is in place, avoiding unnecessary energy waste and extending the lifespan of the lighting device 4. The rotating ring 26 rotates, causing the cleaning rod to move and clean the surface of the detector head 3, keeping the lens of the detector head 3 clean and ensuring the accuracy of license plate recognition and vehicle monitoring, avoiding missed or false detections due to dirt. The lighting lamp 29 rotates away from the parking lot 1 to illuminate the front of the vehicle, providing sufficient supplementary light for the license plate at night or in low light conditions. The supplementary lighting of the detector head 3 and the lighting lamp 29 ensures the data quality of license plate recognition and vehicle monitoring, which is crucial for IoT monitoring.

[0032] When the pull plate 23 moves, it drives the sliding rod 34 to move. The movement of the sliding rod 34 releases the obstruction of the push block 35, thus releasing the limit of the inner rod 33. The inner rod 33 can then move towards the rotating baffle 37. The movement of the sliding rod 34 drives the limit rod 36 to move, which releases the limit of the rotating baffle 37. The rotating baffle 37 can then rotate, and the sliding push plate 38 can push the connecting rod 39 to move. The connecting rod 39 can then push the rotating baffle 37 to rotate. The rotation of the rotating baffle 37 causes the deep groove and shallow groove to rotate. The movement of the inner rod 33 causes the round rod to move towards the inside of the shallow groove. When the rotating baffle 37 rotates, the round rod can generate friction with the shallow groove, reducing the rotation speed of the rotating baffle 37. When the rotating baffle 37 is fully rotated out, the round rod will contact the inside of the deep groove, limiting the rotation of the rotating baffle 37. This allows the rotating baffle 37 and the blocking plate 5 to block the wheels. When it is time to drive away, the system is controlled via the Internet of Things. When motor 31 is started, it drives fixed rod 32 to rotate. The rotation of fixed rod 32 drives rotating baffle 37 to rotate back to its original position via inner rod 33, thus releasing the obstruction of the wheel. When rotating baffle 37 rotates, friction is generated between the round rod and the shallow groove, reducing the rotation speed of rotating baffle 37 and making the blocking action complete slowly and gradually, avoiding impact damage to the vehicle chassis or tires. Rotating baffle 37 and baffle 5 together block the wheel, forming front and rear clamping or double-sided limiting, enhancing the blocking effect. After rotating baffle 37 has completely rotated out, the round rod contacts the inside of the deep groove, finally locking rotating baffle 37 to prevent the baffle from retracting due to vehicle impact. When the vehicle needs to leave, motor 31 is started via IoT control, driving fixed rod 32 to rotate, which drives rotating baffle 37 to rotate back to its original position via inner rod 33. Managers or vehicle owners can remotely control the baffle to reset via IoT platform, without the need for manual on-site operation.
