Description

Technical Field

[0001] This invention relates to the field of intelligent flat-panel parking locks, and more specifically to a ground-mounted intelligent flat-panel parking lock. Background Technology

[0002] Smart tablet parking locks are typically installed in on-street public paid parking spaces. When a vehicle is parked for more than the set free time, the panel rises to lock the car. The owner can then pay the fee and unlock the car safely by scanning the QR code on the lock using WeChat or Alipay. The use of smart tablet parking locks allows for payment throughout the entire charging period, ensuring that all fees are collected and effectively reducing the rate of evasion.

[0003] Existing parking space locks have the following drawbacks:

[0004] 1. Current parking locks mostly use worm gear self-locking transmission mechanisms to prevent the flap from lowering and causing toll evasion. Chinese patent CN118600899A proposes a mechanism where a drive block moves one end of a connecting arm, while the other end of the connecting arm rotates relative to the drive block, causing the other end of the connecting arm to rotate the flap around the drive axis. This achieves a smaller mechanism, thus reducing the size of the mechanism. However, when the flap is impacted, the drive block experiences unidirectional force, making the mechanism prone to jamming and damage. Therefore, a mechanism with more stable force distribution is needed, meaning that the disclosed parking lock still has problems.

[0005] 2. In poor lighting conditions or at night, drivers often struggle to see the locking status of parking locks, especially in parking lots or street-side parking spaces equipped with locks. This can lead to accidental parking in spaces where the lock is locked, potentially causing damage to the vehicle or the lock itself. To address this issue, Chinese patent CN221345374U provides a ground-mounted smart parking lock that disables and activates the lock without requiring the driver to get out of the vehicle. An angle sensor and warning light strip monitor the opening and closing status of the limit plate in real time and display different warning colors accordingly, providing interactive linkage for smart parking or roadside paid parking projects. However, the following problem remains: the warning light strip on the lock body is not easily visible during the day, potentially leading to drivers being unaware of the lock's status and causing accidents or disputes. Therefore, a voice prompt function based on human proximity is needed.

[0006] 3. When the flap is raised, if the vehicle starts unexpectedly, it may scrape the vehicle chassis (or tires), causing damage. To solve this problem, Chinese patent CN109610377A connects the output end of the motor to the input end of a worm gear mechanism; the output end of the worm gear mechanism is connected to the input end of a magnetic coupling; the output end of the magnetic coupling is connected to the input end of a planetary reducer; and the output end of the planetary reducer is connected to a baffle. This ensures that when the baffle is subjected to a torque exceeding the overload protection torque of the device, the magnetic coupling will slip due to overload, thus protecting the motor and other mechanical transmission structures. However, the following problems remain: slippage can easily lead to people evading payment, and the magnetic coupling has a large structural space and high cost. Therefore, a more advanced design is needed to solve this problem. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a ground-mounted intelligent flat parking lock with multiple detection functions, which can detect when a vehicle approaches, thereby improving the safety of the equipment operation.

[0008] The objective of this invention is achieved through the following technical solution: This ground-mounted intelligent flat-panel parking space lock comprises:

[0009] The bottom frame has a rectangular cabin structure with extended edges around the cabin. Functional modules are set on one side of the bottom frame, and transmission and detection modules are set on the other side of the bottom frame.

[0010] The flap is located in the middle of the bottom frame. One side of the flap is supported on the bottom frame by the flap shaft. The side of the flap away from the flap shaft is fitted with a bellows cover between it and the bottom frame. When the flap shaft drives the flap to rotate, the flap opens and closes relative to the bottom frame, and the bellows cover forms a shield for the inner cavity of the bottom frame.

[0011] The transmission module includes a motor and a transmission assembly driven by the motor, the transmission assembly being used to connect and drive the flap shaft to rotate;

[0012] The functional module includes a prompting component, a solar panel, and a power supply control component. The solar panel is used to charge the power supply control component. The power supply control component is electrically connected to the prompting component and the motor to realize power supply and signal control. The prompting component is used to emit a voice reminder signal when a person approaches.

[0013] The detection module is used to sense the position of the vehicle relative to the parking lock and send a vehicle proximity signal to the power supply control component; and

[0014] The sensing component is installed on the top of the flap away from the flap axis. It is used to sense the vehicle chassis by contact and send the contact signal to the power supply control component. The power supply control component controls the motor to work and drive the flap to lower.

[0015] As a further technical solution, the transmission assembly includes a lead screw driven by a motor and a nut mounted on the lead screw. A connecting rod is rotatably connected to both sides of the nut, and a rocker arm is rotatably connected to the other end of each connecting rod. The rocker arm is stacked on the outside of the connecting rod and clamped onto the rotating shaft. The rotating shaft is connected to the flip plate shaft for transmission.

[0016] As a further technical solution, the transmission components and motor are installed in the chassis, which is fixed in the bottom frame. A large cover is installed on the top of the chassis. After the rotating shaft passes through the chassis, it is connected to the flip plate shaft through a coupling. The coupling is supported in the bottom frame by a coupling support seat. The end of the flip plate shaft away from the coupling is supported by a shaft support cover and a shaft support base.

[0017] As a further technical solution, an induction magnet is provided at the end of the rotating shaft installed on the shaft support base, and an angle encoder is also installed outside the shaft support base to cooperate with the induction magnet to monitor the rotation angle of the flip plate in real time and send the angle signal to the power supply control component.

[0018] As a further technical solution, the sensing component includes a main protective strip installed on the end of the flap away from the flap axis, secondary protective strips installed on the flaps on both sides of the main protective strip, and a sensing strip embedded in the main protective strip. When the vehicle touches the sensing strip, the sensing strip sends a contact signal to the power supply control component.

[0019] As a further technical solution, at least one end of the flip plate shaft is fitted with a torsion spring, one end of which abuts against the flip plate, and the other end contacts the limiting structure set inside the bottom frame.

[0020] As a further technical solution, a gap is left between the side of the flap near the flap shaft and the bottom frame for inserting a U-shaped groove. The back of the U-shaped groove is fixed to the inner wall of the bottom frame. A telescopic strip is slidably installed on the open side of the U-shaped groove by a spring. The telescopic strip is used to fit tightly against the flap, forming a dynamic seal at the gap. A wiring conduit is set below the U-shaped groove for wiring between the functional module, the transmission module, and the detection module. Cover plates are set on the bottom frames on both sides of the bellows cover.

[0021] As a further technical solution, the functional module also includes a functional board. The solar panel is mounted on the functional board through a layer of foam, serving as the solar module. The prompting component includes a lampshade, a QR code sign, and a voice speaker, which are sequentially mounted on the functional board. A slot is cut into the functional board at a position corresponding to the lampshade. A light strip is placed into the slot and the lampshade is covered. The QR code sign is installed in the corresponding slot on the functional board. The functional board also has holes for installing the voice speaker and a human body sensor. The human body sensor is electrically connected to the voice speaker to send a human body proximity signal, and the voice speaker emits a voice reminder signal.

[0022] As a further technical solution, several support columns can be detachably installed in the vertical direction inside the bottom frame. When the flap closes relative to the bottom frame, the support columns provide support for the flap. Reinforcing ribs are provided on the back of the function board. The power supply control component is located below the function board. The power supply control component includes a battery module and a control board module. Several support columns are also provided below the function board for support.

[0023] As a further technical solution, the detection module includes a maintenance plate on which an ultrasonic probe and a multi-mode detection module are mounted. The ultrasonic probe is assembled with the maintenance plate via a probe bracket and a slot, and the multi-mode detection module is assembled with the maintenance plate via a detection housing and a slot. The multi-mode detection module uses radar and light sensing to cooperate with the ultrasonic probe to achieve vehicle position detection. A flip-up detection sensor is provided on the flip-up plate to cooperate with the detection module to achieve vehicle position detection.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. The function board area of ​​the lock body only contains some functional components and power supply control modules. The function board is relatively narrow, which makes it easier for the flip panel to be closer to the outside when installed in the parking space. It can also provide a noticeable reminder to the left and right when the lock body is in use. The light strip has the function of being noticeable at night. The reminder component on the function board uses a human body induction sensor to identify the area when a person approaches, and then transmits the information to the voice speaker for auxiliary reminder, thereby improving the safety of the device operation.

[0026] 2. The main protective strip and the two side auxiliary protective strips of the flap are made of elastic material to effectively protect the tires and vehicle chassis from being scratched. The main protective strip is embedded with a sensor strip. The sensor strip contacts and transmits a signal to the power supply control component (control board module) to perform the mechanical lowering movement of the flap. The instantaneous impact force is dissipated to protect the mechanical structure. The induction magnet, together with the angle encoder, monitors the rotation angle of the flap in real time, so that the flap only lowers by a certain angle when it is lowered, and does not fall completely, to prevent vehicles from maliciously evading payment.

[0027] 3. The bellows cover, telescopic strip device, and cover plate protect the internal structure of the lock body during operation, making it more durable in harsh environments;

[0028] 4. The multiple detection devices on the inspection plate and the flip-plate detection device on the flip plate form a multi-detection system, which has the advantages of high detection rate and convenient maintenance.

[0029] 5. The support columns on the bottom frame, the coupling support seat on one side of the flap shaft, and the shaft support base on the other side ensure the pressure resistance of the equipment during operation and when not in operation.

[0030] 6. The double-linkage double-rocker arm design avoids the problem of insufficient torque or increased friction coefficient of the drive structure caused by insufficient torque caused by the imbalance of left and right torques under large torque drive of single rocker arm single link, which leads to component wear.

[0031] 7. The equipment adopts a compact design, with its height controlled within the 10cm asphalt layer thickness range, improving the convenience and reliability of installation;

[0032] 8. The hinge on one side of the flap adopts a semi-circular upper and lower screw fixing design, which provides convenience for quick disassembly for on-site maintenance and improves on-site operation and maintenance efficiency. Attached Figure Description

[0044] The present invention will now be described in detail with reference to the accompanying drawings:

[0045] Example: As attached Figures 1-10 As shown, this ground-mounted intelligent flat parking lock includes a base frame 11, a battery module 12, a control board module 13, a support column 14, a shaft support base 15, a shaft support cover 16, a coupling support seat 17, a telescopic strip 18, a cover plate 19, a wiring conduit 20, a maintenance plate 21, a probe bracket 22, a detection housing 23, an ultrasonic probe 24, a large cover 31, a housing 32, a motor 33, a nut 34, a lead screw 35, a rocker arm 36, a rotating shaft 37, a coupling 38, and a flap. 41.

[0046] Reference Appendix Figure 2 , 3 The base frame 11 has a rectangular cabin structure with extended edges around its perimeter. A functional module is located on one side of the base frame 11, while a transmission module and a detection module are located on the other side. Preferably, several support columns 14 are detachably installed vertically inside the base frame 11. When the flap 41 is closed relative to the base frame 11, the support columns 14 provide support for the flap 41. Several fixing holes are provided at the bottom of the base frame 11 for easy fixing of the base frame 11 to the parking space via threaded connections.

[0047] like Figure 1 , 2As shown, the flap 41 is located in the middle of the base frame 11. One side of the flap 41 is supported on the base frame 11 by a flap shaft 45. A bellows cover 51 is installed between the other side of the flap 41 (i.e., the side away from the flap shaft 45) and the base frame 11. When the flap shaft 45 drives the flap 41 to rotate, the other side of the flap 41 opens and closes relative to the base frame 11, using the bellows cover 51 to shield the inner cavity of the base frame 11. Cover plates 19 are fixedly installed on the base frame 11 on both sides of the bellows cover 51. The cover plates 19 serve to separate the flap 41 and the bellows cover 51 from the functional modules, transmission modules, and detection modules. Preferably, as shown... Figure 8 As shown, a main protective strip 43 is installed on the side of the flap 41 away from the flap shaft 45. Secondary protective strips 44 are installed on the flaps 41 on both sides of the main protective strip 43. A sensing strip 71 is embedded within the main protective strip 43. The sensing strip 71, main protective strip 43, and secondary protective strip 44 serve as a sensing component, capable of contact sensing of the vehicle chassis. When the vehicle contacts the sensing strip 71, the sensing strip 71 sends a contact signal to the control board module 13 of the power supply control component. The power supply control component (control board module 13) then controls the motor 33 to operate, driving the flap 41 to lower. Preferably, the main protective strip 43 and secondary protective strip 44 are made of elastic material, effectively protecting the tires and vehicle chassis from scratches.

[0048] Reference Appendix Figure 2 , 9 The transmission module includes a motor 33 and a transmission assembly driven by the motor. The transmission assembly includes a lead screw 35 driven by the motor 33 and a nut 34 mounted on the lead screw 35. A connecting rod 77 is rotatably connected to both sides of the nut 34. The other end of each connecting rod 77 is rotatably connected to a rocker arm 36. The rocker arm 36 overlaps the outside of the connecting rod 77 and is clamped onto a rotating shaft 37. The rotating shaft 37 is connected to the flap shaft 45 for transmission. The transmission assembly (transmission module) drives the flap shaft 45 to rotate. This double-connecting-rod, double-rocker-arm design avoids the problem of unbalanced torque on the left and right sides under large torque driving conditions with a single rocker arm and single connecting rod, which can lead to insufficient torque or increased friction coefficient in the drive structure, causing component wear.

[0049] Furthermore, the transmission assembly and motor 33 are both installed inside the housing 32, which is fixed within the base frame 11 (the housing 32 has mounting positions on both sides designed to match the base frame 11). A large housing cover 31 is installed on the top of the housing 32. The rotating shaft 37 passes through the housing 32 and is connected to the flap shaft 45 via a coupling 38. Preferably, the coupling 38 is supported within the base frame 11 by a coupling support 17. Simultaneously, the end of the flap shaft 45 furthest from the coupling 38 is supported by a shaft support cover 16 and a shaft support base 15. The shaft support cover 16 and the shaft support base 15, when assembled, form a shaft hole. Figure 8As shown, an induction magnet 74 is provided at the end of the rotating shaft 37 mounted on the shaft support base 15. An angle encoder 73 is also mounted outside the shaft support base 15, which can work with the induction magnet 74 to monitor the rotation angle of the flap 41 in real time and send the angle signal to the power supply control component (control board module 13). The control board module 13 controls the lowering angle of the flap 41 according to the angle signal of the angle encoder 73. It usually does not lower completely to prevent vehicles from maliciously evading payment. It can be set to lower a certain angle with a single instantaneous impact. The multi-angle flap lowering action can prevent the flap from getting stuck in the chassis and provide multiple blocking reminders to prevent payment evasion.

[0050] like Figure 2 , 10 As shown, a gap is left between the flap 41 and the bottom frame 11 on the side near the flap shaft 45, and a U-shaped groove 76 is inserted therein (preferably, the U-shaped groove 76 can be made of U-shaped channel steel). The back of the U-shaped groove 76 is fixed to the inner wall of the bottom frame 11. The opening side of the U-shaped groove 76 is slidably mounted with a telescopic strip 18 via a spring 75. The telescopic strip 18 can fit tightly against the flap 41, thereby forming a dynamic seal at the gap. Preferably, a conduit 20 is provided below the U-shaped groove 76. The conduit 20 facilitates the wiring between the functional module, the transmission module, and the detection module. Figure 2 , 3 As shown in Figure 4, cover plates 19 are provided on the bottom frames 11 on both sides of the bellows cover 51, which can protect the internal structure of the lock body when the lock body is running and make it more durable in harsh environments.

[0051] Reference Appendix Figure 2 , 8 A torsion spring 72 is fitted at one or both ends of the flip plate shaft 45. One end of the torsion spring 72 abuts against the flip plate 41, and the other end of the torsion spring 72 contacts the limiting structure set inside the bottom frame 11. The torsion spring 72 is used to assist in raising the plate angle and eliminate the gaps in the transmission mechanism and the machining tolerances of the parts, so that the flip plate can be raised and lowered smoothly.

[0052] like Figure 3 , 5 As shown in Figure 6, the functional module includes a prompting component, a solar panel, a power supply control component, and a function board 61. A solar panel 65 is mounted on the function board 61 via a layer of foam 64, serving as the solar panel and capable of charging the power supply control component. The prompting component includes a lampshade 63, a QR code sign 68, and a voice speaker 66, sequentially mounted on the function board 61. A slot is cut into the function board 61 at a position corresponding to the lampshade 63, and a light strip 62 is inserted into the slot to cover the lampshade 63. The QR code sign 68 is installed in a corresponding slot on the function board 61. The function board 61 also has holes for mounting the voice speaker 66 and a human body sensor 67, with the human body sensor 67 electrically connected to the voice speaker 66. Preferably, as shown... Figure 6As shown, a reinforcing rib 70 is provided on the back of the function board 61. The power supply control assembly is located below the function board 61, and includes a battery module 12 and a control board module 13, as shown... Figure 4 As shown, several support columns 14 are also provided below the mounting position of the function board 61 to facilitate support and prevent damage to the power supply control component. This power supply control component is electrically connected to the indicator component and the motor 33 to achieve power supply and signal control. Since the area surrounding the function board 61 only contains some functional components and the power supply control component, the function board 61 is relatively narrow, allowing the flip-up plate 41 to be positioned closer to the outside when the function board 61 is installed in the parking space, providing a more prominent left and right reminder when the lock is in use. The light strip 62 also serves as a prominent nighttime reminder. The reminder component on the function board 61 can identify the area when a person approaches via the human body sensor 67, thereby transmitting a signal to the voice speaker 66 to provide an auxiliary reminder, thus improving the safety of the equipment operation.

[0053] like Figure 1 , 3 As shown in Figure 7, the detection module can sense the vehicle's position relative to the parking lock in real time. The power supply control component is electrically connected to the detection module to achieve power supply and communication. Further, the detection module includes a maintenance plate 21, on which an ultrasonic probe 24 and a multi-mode detection module are mounted. One side of the maintenance plate 21 has slots for mounting the ultrasonic probe 24 and the multi-mode detection module, as well as a wiring hole; the other side has reinforcing ribs and a wiring channel. The ultrasonic probe 24 is assembled with the maintenance plate 21 via a probe bracket 22 in a slot-like manner. After installation, the ultrasonic probe 24 is slightly higher than the maintenance plate 21. The multi-mode detection module is assembled with the maintenance plate 21 via a detection housing 23 in a slot-like manner. The multi-mode detection module uses radar and light sensing detection, and can work with the ultrasonic probe 24 to achieve vehicle position detection. In addition, as... Figure 1 , 8 As shown, a flip-board detection sensor 42 is provided on the flip-board 41. The flip-board detection sensor 42 can work with the detection module to realize vehicle position detection, forming multiple detections, which has the advantages of high detection rate and better maintenance.

[0054] The device of this invention adopts a compact design, controlling its height within the 10cm asphalt layer thickness range, thus improving the convenience and reliability of installation. Meanwhile, the shaft fixing on one side of the flap uses a semi-circular upper and lower design with screws, providing convenient disassembly for on-site maintenance and improving on-site operation and maintenance efficiency.

[0055] The working process of this invention:

[0056] When the parking lock is working, the motor 33 drives the lead screw 35 to rotate, and the nut 34 slides relative to the lead screw 35, thereby driving the connecting rods 77 on both sides of the nut 34. The two connecting rods 77 then drive the two rocker arms 36 to rotate, realizing the angular rotation of the rotating shaft 37. One end of the rotating shaft 37 protrudes from the housing 32 and is connected to the coupling 38, thereby driving the flap 41 (flap shaft 45) to rotate at an angle. When the flap shaft 45 drives the flap 41 to rotate, the other end of the flap 41 opens and closes relative to the bottom frame 11, and the bellows cover 51 forms a shield for the inner cavity of the bottom frame 11. During the rotation of the flap 41 relative to the bottom frame 11, the telescopic strip 18 can stick to the flap 41 under the action of the spring 75, thereby forming a dynamic seal at the gap.

[0057] When a vehicle enters a parking space, the detection module (ultrasonic probe 24, multi-mode detection module, and flap detection sensor 42) senses the approach and sends a vehicle approach signal. Upon receiving the signal, the control board module 13 controls the flap 41 to rise. If a vehicle accidentally drives out while the flap 41 is raised, the sensing strip 71 first contacts the vehicle chassis and sends a contact signal to the control board module 13 of the power supply control component. The power supply control component (control board module 13) then controls the motor 33 to drive the flap 41 to lower. The main protective strip 43 and the secondary protective strip 44 are made of elastic material, effectively protecting the tires and vehicle chassis from scratches. Simultaneously, the control board module 13 controls the lowering angle of the flap 41 based on the angle signal from the angle encoder 73. It typically does not lower completely to prevent vehicles from maliciously evading payment. It can be set to lower a certain angle with each instantaneous impact; the multi-angle flap descent prevents the flap from jamming the chassis and provides multiple warnings to prevent payment evasion. In addition, the torsion spring 72 is used to assist in adjusting the lifting angle and to eliminate the gap between the transmission mechanism and the machining tolerance of the parts, so that the flap 41 can be lifted and lowered smoothly.

[0058] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this invention should fall within the scope of protection of the appended claims.
