Description

Technical Field

[0001] This utility model relates to the field of parking space anti-occupancy structure technology, and in particular to parking space locks. Background Technology

[0002] With the widespread application of intelligent parking management systems, license plate recognition technology is widely used in smart parking locks. In existing technologies, most license plate recognition parking locks place the camera separately at the edge of the parking space or other locations within the parking lot, and complete the license plate recognition and locking operations through communication with the main body of the parking lock.

[0003] In existing technologies, the separate installation of the camera and the parking lock body makes the wiring and installation process of the entire system more complicated. Additional cables and transmission equipment need to be laid around the parking space, which increases the overall cost and installation time of the system. Placing the camera separately next to the parking space not only increases the space occupied by the parking space, but may also affect the aesthetics of the parking lot. Especially in urban environments, the appearance and design of the equipment usually need to be coordinated with the surrounding environment. Moreover, traditional parking locks cannot adjust or clear the internal camera, and cannot improve the multi-angle and clear recognition function. Utility Model Content

It requires additional cables and transmission equipment to be laid around the parking space, which increases the overall cost and installation time of the system. Placing the camera separately next to the parking space not only increases the space occupied by the parking space, but may also affect the aesthetics of the parking lot. Especially in urban environments, the appearance and design of the equipment usually need to be coordinated with the surrounding environment. Moreover, traditional parking space locks cannot adjust or clean the internal camera, and cannot improve the multi-angle and clear recognition function.

[0009] Preferably, the fixing base includes a lower base and an upper base. The lower base is welded to the surface of the base, and the upper base and the lower base are fixedly connected by bolts.

[0027] Reference Figure 1-6The parking lock includes a base 1, a fixed seat 2 on the surface of the base 1, support rods 3 on both sides of the fixed seat 2, and a connecting shell 4 between the two support rods 3. A camera 15 and a main control system are housed inside the connecting shell 4. A connecting shaft 8 is housed inside the fixed seat 2, and a drive mechanism for rotating the connecting shaft 8 is also located inside the fixed seat 2. The two support rods 3 are respectively mounted at both ends of the connecting shaft 8. A transparent plate is provided on the surface of the connecting shell 4, and a cleaning mechanism for cleaning the transparent plate is located inside the connecting shell 4. The two support rods 3 are mounted on both sides of the fixed seat 2 via the connecting shaft 8, and the connecting shell 4 is installed between the two support rods 3, thereby enabling the two support rods to rotate. Rod 3 and connecting shell 4 form a "U" shaped structure. When the parking space is locked, the two rods 3 are vertical. When a vehicle is in front of the connecting shell 4, camera 15 captures and records the license plate information, transmitting the information to the main control system for analysis. Camera 15 uses a high-resolution CSI camera, and the main control system uses a high-performance embedded processor. This integrated design ensures more stable communication between camera 15 and the main control system, and reduces the complexity of external wiring and equipment installation. Camera 15 is a high-definition camera, supporting nighttime license plate recognition and equipped with intelligent automatic exposure technology to adapt to different lighting conditions. The system uses a Raspberry Pi 4B, which boasts powerful computing capabilities and supports the rapid execution of license plate recognition algorithms. The main control system not only integrates circuitry for controlling parking lock switches but also incorporates communication interfaces (such as a Wi-Fi module) for data interaction with external smart devices like mobile apps and license plate recognition systems. When the main control system detects a license plate requiring unlocking, it commands the drive mechanism to rotate the connecting shaft 8, causing the two support rods 3 to rotate forward, thus unlocking the vehicle. If the main control system recognizes a license plate that is not a pre-set one, it will not command the drive mechanism to operate, preventing the vehicle from entering. The main control system is equipped with a Wi-Fi module to enable... With real-time connection to the car owner's mobile phone, the car owner can directly control the parking lock, check the parking space status, and perform parking management operations through a mobile app. The internal high-efficiency lithium battery of the connecting shell 4 ensures that the system can still work normally without external power. The parking lock system uses high-precision license plate recognition technology and advanced image processing algorithms to automatically identify the license plates of vehicles entering and exiting, ensuring that the parking spaces parked by car owners are effectively managed. At the same time, the parking lock system can be integrated with an intelligent parking management system to monitor the status of parking spaces and analyze data through a cloud platform. Car owners can view the real-time status of parking spaces through the app, and the system can automatically perform functions such as parking space reservation and payment settlement.

[0028] Furthermore, the drive mechanism includes a first motor 7, which is fixedly installed inside the fixed base 2. A worm gear 10 is fixedly installed at the output shaft port of the first motor 7, and a worm wheel 9 is fixedly installed on the surface of the connecting shaft 8. The worm gear 10 and the worm wheel 9 mesh. In use, the drive mechanism transmits commands to the first motor 7, which drives the worm gear 10 to rotate. The worm gear 10 drives the worm wheel 9 to rotate, and the worm wheel 9 drives the connecting shaft 8 to rotate, thereby using the connecting shaft 8 to drive the two support rods 3 to rotate synchronously.

[0029] Furthermore, both ends of the connecting shaft 8 are threaded, and round blocks 6 are fixedly installed on the surface of the connecting shaft 8 near both ends. Nuts 5 are threadedly connected to the surface of the connecting shaft 8 at the two threaded positions. The two support rods 3 are clamped by the round blocks 6 and the nuts 5 respectively. A rubber gasket is provided between the nut 5 and the support rod 3. Both support rods 3 are installed on the connecting shaft 8 by the round blocks 6 and the nuts 5. That is, the support rods 3 are installed by clamping the nuts 5 and the round blocks 6. A rubber gasket is also provided between the nuts 5 and the support rods 3, so that the support rods 3 can still rotate with the connecting shaft 8 after being clamped. With this design, when the car owner needs to enter the parking space but does not notice whether the parking space lock is closed, the vehicle will rotate after hitting the support rod 3, reducing damage to the vehicle and the parking space lock.

[0030] Furthermore, the fixed base 2 includes a lower base 21 and an upper base 22. The lower base 21 is welded to the surface of the base 1, and the upper base 22 and the lower base 21 are fixedly connected by bolts. The two ends of the connecting shell 4 are fixedly connected to the two support rods 3 by bolts respectively. The base 1 is fixedly connected to the ground by bolts. The fixed base 2 is used to install the connecting shaft 8 and the drive mechanism. By adopting a split structure of upper base 22 and lower base 21, it is convenient to install and disassemble.

[0031] Furthermore, a T-shaped shaft 16 is rotatably connected inside the connecting shell 4. The camera 15 is fixedly mounted on the surface of the T-shaped shaft 16. A second motor 17 is fixedly mounted inside the connecting shell 4. The output shaft port of the second motor 17 is fixedly connected to the T-shaped shaft 16. The camera 15 is mounted on the T-shaped shaft 16 and can be driven to rotate by the second motor 17. When a vehicle approaches, the camera 15 detects the vehicle and transmits a signal to the main control system. The main control system then transmits a signal to the second motor 17, commanding the second motor 17 to drive the T-shaped shaft 16 to rotate slowly back and forth at a small angle. The camera 15 can better capture the frontal image of the license plate, especially when the license plate is at a relatively skewed position.

[0032] Furthermore, the cleaning mechanism includes a connecting rod 13, with cleaning cotton 14 fixedly installed on the surface of the connecting rod 13. A limiting rod 11 is fixedly installed on the side wall of the connecting rod 13, and the limiting rod 11 is slidably connected inside the connecting shell 4. An electric push rod 12 is fixedly installed inside the connecting shell 4, and the output port of the electric push rod 12 is fixedly connected to the connecting rod 13. The camera 15 is covered inside the connecting shell 4 by a transparent plate. Since the parking lock is close to the ground, dust, dirt and other impurities are easily affected by the clarity of the camera 15. The main control system can be used to control the electric push rod 12 to push the connecting rod 13 to move, thereby using the cleaning cotton 14 on the surface of the connecting rod 13 to clean the transparent plate. The limiting rod 11 can guide the connecting rod 13, and serve to protect the electric push rod 12 and stabilize the operation of the connecting rod 13.

[0033] In summary, two support rods 3 are mounted on both sides of the fixed base 2 using connecting shafts 8, and the connecting shell 4 is installed between the two support rods 3, thus forming a "U"-shaped structure. When the parking space is locked, the two support rods 3 are in a vertical position. When a vehicle is in front of the connecting shell 4, the camera 15 will capture and record the license plate information and transmit the information to the main control system for analysis. The camera 15 uses a high-resolution CSI camera, and the main control system uses a high-performance embedded processor. This integrated design ensures more stable communication between the camera 15 and the main control system and reduces the complexity of external wiring and equipment installation. The camera 15 is a high-definition camera, supports nighttime license plate recognition, and is equipped with intelligent... Automatic exposure technology adapts to different lighting conditions. The main control system is a Raspberry Pi 4B with powerful computing capabilities, supporting the rapid execution of license plate recognition algorithms. The main control system not only integrates the circuitry for controlling the parking lock switch but also incorporates a communication interface (such as a Wi-Fi module) for data interaction with external smart devices like mobile apps and license plate recognition systems. When the main control system detects a license plate requiring unlocking, it commands the drive mechanism to rotate the connecting shaft 8, thereby causing the two support rods 3 to rotate forward, unlocking the vehicle. When the main control system recognizes a license plate that is not a pre-set one, it will not command the drive mechanism to operate, thus preventing the vehicle from entering. The main control system is equipped with a Wi-Fi module for real-time communication with the vehicle owner's mobile phone. The system connects to a mobile app, allowing car owners to directly control the parking lock, check parking space status, and manage the parking lot. The internal casing 4 is equipped with a high-efficiency lithium battery, ensuring the system can function normally without an external power source. The parking lock system uses high-precision license plate recognition technology and advanced image processing algorithms to automatically identify license plates of vehicles entering and exiting, ensuring effective management of parking spaces. Simultaneously, the system can integrate with an intelligent parking management system, monitoring parking space status and analyzing data through a cloud platform. Car owners can view the real-time status of their parking spaces via the app. The system can automatically perform functions such as parking space reservation and payment settlement. During operation, the drive mechanism transmits commands to the first motor 7, which drives the worm gear 10 to rotate. 10 drives the worm gear 9 to rotate, which in turn drives the connecting shaft 8 to rotate. This, in turn, causes the two support rods 3 to rotate synchronously via the connecting shaft 8. Both support rods 3 are mounted on the connecting shaft 8 via round blocks 6 and nuts 5. Specifically, the support rods 3 are mounted by the clamping of the nuts 5 and round blocks 6. A rubber gasket is also placed between the nuts 5 and the support rods 3, allowing the support rods 3 to rotate relative to the connecting shaft 8 even after being clamped. This design allows the support rods to rotate if a driver enters a parking space without noticing whether the parking lock is closed, reducing damage to the vehicle and the parking lock. The mounting base 2 is used to mount the connecting shaft 8 and the drive mechanism. Its separate upper and lower mounting structures (22 and 21) facilitate installation and disassembly.Camera 15 is mounted on T-shaped shaft 16 and can be driven to rotate by second motor 17. When a vehicle approaches, camera 15 detects the vehicle and transmits a signal to the main control system. The main control system then transmits the signal to second motor 17, commanding second motor 17 to drive T-shaped shaft 16 to rotate slowly back and forth at a small angle. Camera 15 can better capture the frontal image of the license plate, especially when the license plate is at a slight angle. Camera 15 is concealed inside connecting shell 4 by a transparent plate. Since the parking lock is close to the ground, dust, dirt, and other impurities can easily affect the clarity of camera 15. The main control system can control electric push rod 12 to push connecting rod 13 to move, thereby using cleaning cotton 14 on the surface of connecting rod 13 to clean the transparent plate. The limiting rod 11 can guide connecting rod 13, protecting electric push rod 12 and stabilizing connecting rod 13.
