Description

Technical Field

[0001] The present invention relates to the technical field of smart parking flap lock plates, and particularly to ground-mounted smart parking flap lock plates.

Background Art

[0002] Smart parking flap lock plates are generally installed in public paid parking spaces on roads. When a vehicle parks beyond the set free time, the flap plate is raised to lock the vehicle. Users can read the QR code on the lock plate body through WeChat or Alipay and make self-settlement payments, so that they can safely leave the warehouse after unlocking. By introducing smart parking flap lock plates, it becomes possible to ensure the collection of fees for the entire parking time and effectively prevent the occurrence of unpaid fees.

[0003] Conventional parking flap lock plates have the following defects.

[0004] 1. Currently, many parking flap lock plates adopt worm gear self-locking in the transmission mechanism to lower the flap and make it difficult to evade fees. In contrast, in Chinese Patent CN118600899A, it is proposed that the drive block moves one end of the connecting arm, and one end of the connecting arm rotates relative to the drive block, so that the other end of the connecting arm rotates the flap around the rotation axis at the drive axis of the flap, with a smaller-sized mechanism that reduces the movement size. However, when the flap collides, the drive block receives force in one direction, and the mechanism is prone to locking and damage. Therefore, a mechanism with more stable force reception is required, and there are still problems with the disclosed parking flap lock plate.

[0005] 2. When users park in a target parking space at night or in poor lighting conditions, especially in parking lots or on-street parking spaces equipped with parking flap locks, it can be difficult to see the status of the parking flap locks. If a vehicle mistakenly enters a space with the lock still raised, it can cause damage to the vehicle or the parking equipment itself. To solve the above problem, Chinese Patent CN221345374U provides a ground-mounted smart parking flap lock that overcomes the shortcomings of the above-mentioned conventional technology. This smart parking flap lock does not require the user to get out of the vehicle to operate it. An angle sensor and warning tape are positioned to monitor the status of the lock in real time and display it with a corresponding different warning color. This enables information sharing with smart parking and roadside paid parking systems. However, during the daytime, the lock warning tape is difficult to see, making it difficult for users to understand the specific status of the lock plate, which can lead to accidents and problems. Therefore, a function that provides an audible alert when someone approaches is necessary.

[0006] 3. When the flap rises, if the vehicle starts unexpectedly, it is more likely to get caught on the vehicle chassis (or tires), causing damage to the vehicle. To solve the above problem, in Chinese patent CN109610377A, the output terminal of the motor is connected to the input terminal of the worm gear mechanism, the output terminal of the worm gear mechanism is connected to the input terminal of the magnetic coupling, the output terminal of the magnetic coupling is connected to the input terminal of the planetary gear reducer, and the output terminal of the planetary gear reducer is connected to the baffle. When the baffle receives a load exceeding the overload protection torque of the device, the magnetic coupling slips due to the overload, protecting the motor and other mechanical transmission structures. However, this is prone to accidental slippage and the magnetic coupling structure is large, resulting in high costs. Therefore, a design with greater performance is needed to solve this problem. [Overview of the project]

[0007] The objective of the present invention is to provide a ground-mounted smart parking flap lock plate that overcomes the drawbacks of the prior art, has a multi-detection function, pays a fee when proximity is established, and improves the operational safety of the equipment.

[0011] As a further technical proposal, an induction magnetic steel is installed at the end of the rotating shaft attached to the shaft support base, and an angle encoder is further installed outside the shaft support base to work in cooperation with the induction magnetic steel to monitor the rotation angle of the flap in real time and transmit the angle signal to the power supply control assembly.

[0012] As a further technical proposal, the sensing assembly includes a main guard bar attached to one end of the flap away from the flap axis, sub-guard bars attached to the flaps on both sides of the main guard bar, and a sensing bar fitted and mounted within the main guard bar, and when a vehicle comes into contact with the sensing bar, the sensing bar transmits a contact signal to the power supply control assembly.

[0013] As a further technical proposal, a torsion spring is fitted to at least one end of the flap shaft, with one end of the torsion spring in contact with the flap and the other end in contact with a position limiting structure provided within the bottom frame.

[0014] As a further technical proposal, there is a gap between the side of the flap closest to the flap axis and the bottom frame for inserting a U-shaped slide groove, the back of which is fixed to the inner wall of the bottom frame, and a retractable bar is slidably attached to the opening side of the U-shaped slide groove by a spring, so that the retractable bar is in close contact with the flap and forms a dynamic seal in the gap, below which an electrical conduit is provided for wiring between the functional module, the transmission module and the detection module, and shielding plates are provided on the bottom frame on both sides of the organ cover.

[0015] As a further technical proposal, the functional module further includes a functional panel, and the solar panel is attached to the functional panel as a solar module via a layer of foamed cotton; the presentation module includes a lampshade, a two-dimensional code board and an audio horn, which are sequentially attached to the functional panel, where a groove is made in the functional panel at a position corresponding to the lampshade, and a light bar is placed in the groove and covered by the lampshade; the two-dimensional code board is attached to a corresponding groove in the functional panel; the functional panel further has holes for attaching an audio horn and a human body detection sensor, the human body detection sensor is electrically connected to the audio horn to transmit a human body proximity signal and emits an audio warning signal via the audio horn.

[Effects of the Invention]

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The lock's function panel area contains only a few functional assemblies and a power supply control module. Because the function panel is relatively narrow, the flap is positioned further outward when installed in a parking space, drawing attention to the left and right when using the lock. Furthermore, the light bar also serves as a nighttime warning function, and the display assembly installed on the function panel uses a human body detection sensor to identify the area and emits a warning sound from the voice horn when a person approaches. This improves the operational safety of the device.

[0020] 2. The main guard bar and sub-guard bars on both sides of the flap are made of elastic material, effectively protecting the tires and vehicle chassis from damage. A sensing bar is fitted and installed inside the main guard bar. When the sensing bar makes contact, it transmits a signal to the power supply control assembly (control panel module) to cause the mechanical structure to descend. The impact force is released instantaneously, protecting the mechanical structure. The inductive magnetic steel works in cooperation with the angle encoder to monitor the rotation angle of the baffle in real time, and when lowering the baffle, it limits the descent angle and prevents it from going all the way down, thus preventing non-payment of fees.

[0021] 3. The organ cover, telescopic bar device, and shielding plate protect the internal structure during the locking operation and enhance durability in harsh environments.

[0022] 4. The multiple types of detection devices provided on the inspection board and the flap detection device on the flap form multiple detections, having the advantages of high detection rate and convenient maintenance.

[0023] 5. Support columns are provided on the bottom frame, a coupling support base is provided on one side of the flap shaft, and a shaft support base is provided on the other side to ensure the pressure resistance of the device during operation and non-operation.

[0024] 6. By adopting the double-link double-rocker arm design, problems such as imbalance of left and right moments, insufficient moment, increased friction coefficient of the drive structure, and wear of parts that may occur when driving a single rocker single link with a large moment can be avoided.

[0025] 7. The whole device adopts a compact design and can fit into an asphalt layer with a height of 10 CM, thereby improving the convenience and reliability of installation.

[0026] 8. The shaft fixation on one side of the flap is designed by combining upper and lower semi-circular shapes with screw fixation, enabling rapid maintenance on-site and improving the efficiency of maintenance work on-site.

[0028] The present invention will now be described in detail with reference to the drawings.

[0029] Example: As shown in Figures 1-10, such a ground-mounted smart parking flap lock plate comprises a bottom frame 11, a battery module 12, a control plate module 13, a support column 14, a shaft support base 15, a shaft support cover 16, a coupling support base 17, a telescopic bar 18, a shielding plate 19, a conduit 20, an inspection plate 21, a probe holder 22, a detection housing 23, an ultrasonic probe 24, a large housing cover 31, a housing 32, a motor 33, a nut 34, a screw 35, a rocker arm 36, a rotating shaft 37, a coupling 38, and a flap. The components include 41, a flap detection sensor 42, a main guard bar 43, a sub-guard bar 44, a flap shaft 45, an organ cover 51, a function panel 61, a light bar 62, a lampshade 63, foamed cotton 64, a solar panel 65, a voice horn 66, a human body detection sensor 67, a two-dimensional code board 68, a reinforcing rib 70, a sensing bar 71, a torsion spring 72, an angle encoder 73, an induction magnetic steel 74, a spring 75, a U-shaped slide groove 76, a link 77, a transmission module, a function module, a detection module, and a sensing assembly.

[0030] Referring to Figures 2 and 3, the bottom frame 11 has a rectangular cabin structure and extends around the cabin. A functional module is provided on one side of the bottom frame 11, and a transmission module and a detection module are provided on the other side. Preferably, a plurality of support columns 14 are detachably mounted vertically within the bottom frame 11, and when the flap 41 is closed relative to the bottom frame 11, the support columns 14 support the flap 41. Multiple fixing holes are provided at the bottom of the bottom frame 11, making it easy to fix the bottom frame 11 to the parking space by screw connections.

[0031] As shown in Figures 1 and 2, the flap 41 is located in the center of the bottom frame 11, one side of the flap 41 is supported by the bottom frame 11 via a flap shaft 45, and an organ cover 51 is attached between the other side of the flap 41 (i.e., the side away from the flap shaft 45) and the bottom frame 11. When the flap shaft 45 rotates the flap 41, the other side of the flap 41 opens and closes relative to the bottom frame 11, and the organ cover 51 shields the cavity of the bottom frame 11. Shielding plates 19 are fixed to the bottom frame 11 on both sides of the organ cover 51, and the shielding plates 19 serve to separate the flap 41 and organ cover 51 from the functional module, transmission module, and detection module. Preferably, as shown in Figure 8, a main guard bar 43 is attached to the side of the flap 41 away from the flap axis 45, sub-guard bars 44 are attached to the flaps 41 on both sides of the main guard bar 43, and a sensing bar 71 is fitted and installed inside the main guard bar 43. The sensing bar 71, main guard bar 43, and sub-guard bars 44 form a sensing assembly that can sense the vehicle chassis in contact with it. When the vehicle comes into contact with the sensing bar 71, the sensing bar 71 transmits a contact signal to the control panel module 13 of the power supply control assembly (control panel module 13), which controls and operates the motor 33 to drive the flap 41 down. Preferably, the main guard bar 43 and sub-guard bars 44 are made of elastic material so that they can effectively protect the tires and vehicle chassis from damage.

[0032] Referring to Figures 2 and 9, the transmission module includes a motor 33 and a transmission assembly driven by the motor. The transmission assembly includes a screw 35 driven by the motor 33 and a nut 34 attached to the screw 35. A link 77 is rotatably connected to both sides of the nut 34. A rocker arm 36 is rotatably connected to the other end of each link 77. The rocker arm 36 is superimposed on the outside of the link 77 and locked to a rotating shaft 37. The rotating shaft 37 is connected to a flap shaft 45 for power transmission, and the transmission assembly (transmission module) rotates the flap shaft 45. By adopting a double-link, double-rocker-arm design, problems such as imbalance of left and right moments, insufficient moment, increased friction coefficient of the drive structure, and wear of parts, which can occur when a single-rocker, single-link design is driven with a large moment, can be avoided.

[0033] Furthermore, both the transmission assembly and the motor 33 are installed inside the housing 32, the housing 32 is fixed inside the bottom frame 11 (mounting positions designed to correspond to the bottom frame 11 are provided on both sides of the housing 32), a housing cover 31 is attached to 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 inside the bottom frame 11 via a coupling support base 17, and one end of the flap shaft 45 away from the coupling 38 is supported via a shaft support cover 16 and a shaft support base 15, and the shaft support cover 16 and shaft support base 15 are assembled to form a shaft hole. As shown in Figure 8, an induction magnetic steel 74 is provided at the end of the rotating shaft 37 attached to the shaft support base 15, and an angle encoder 73 is further attached to the outside of the shaft support base 15, so that the rotation angle of the flap 41 can be monitored in real time in accordance with the induction magnetic steel 74 and the angle signal can be transmitted to the power supply control assembly (control panel module 13). The control panel module 13 controls the descent angle of the flap 41 based on the angle signal from the angle encoder 73, preventing it from descending completely and thus preventing non-payment of fees. The system can be set to lower the baffle to a certain angle with a single instantaneous impact, or to drop the baffle at multiple angles, thereby preventing the baffle from getting caught on the chassis and preventing non-payment of fees by activating the stopper multiple times.

[0034] As shown in Figures 2 and 10, there is a gap between the side of the flap 41 closest to the flap shaft 45 and the bottom frame 11, and a U-shaped slide groove 76 (preferably the U-shaped slide groove 76 may be made of U-shaped groove steel) is provided, the back of which is fixed to the inner wall of the bottom frame 11, and an extendable bar 18 is slidably attached to the opening side of the U-shaped slide groove 76 by a spring 75, so that the extendable bar 18 can be tightly pressed against the flap 41, thereby forming a dynamic seal in the gap. Preferably, a conduit 20 is provided below the U-shaped slide groove 76, and the conduit 20 facilitates circuit wiring between the functional module, the transmission module and the detection module. As shown in Figures 2, 3 and 4, shielding plates 19 are installed on the bottom frame 11 on both sides of the organ cover 51 to protect the internal structure when the lock is operated and to increase durability in harsh environments.

[0035] As shown in Figures 2 and 8, torsion springs 72 are fitted to one or both ends of the flap shaft 45, with one end of the torsion spring 72 in contact with the flap 41 and the other end of the torsion spring 72 in contact with a position limiting structure provided inside the bottom frame 11. The torsion springs 72 are used to assist in the lift angle and eliminate gaps in the transmission mechanism and part machining tolerances, thereby ensuring smooth raising and lowering of the flap.

[0036] As shown in Figures 3, 5, and 6, the functional module includes a presentation assembly, a solar assembly, a power supply control assembly, and a functional panel 61. The solar panel 65 is attached to the functional panel 61 via a layer of foamed cotton 64 and, as the solar assembly, can charge the power supply control assembly. The presentation assembly includes a lampshade 63, a two-dimensional code board 68, and a voice horn 66, which are sequentially attached to the functional panel 61. A groove is provided in the functional panel 61 at a position corresponding to the lampshade 63, and a light bar 62 is placed in the groove and covered by the lampshade 63. The two-dimensional code board 68 is mounted in a slot provided corresponding to the functional panel 61, and the functional panel 61 is further provided with holes for mounting the voice horn 66 and a human body detection sensor 67, the human body detection sensor 67 being electrically connected to the voice horn 66. As shown in Figure 6, it is preferable to provide reinforcing ribs 70 on the back of the functional panel 61. The power supply control assembly is located below the functional panel 61 and includes a battery module 12 and a control board module 13. As shown in Figure 4, multiple support columns 14 are provided below the mounting position of the functional panel 61 to stabilize the support and prevent damage to the power supply control assembly. The power supply control assembly is electrically connected to the display assembly and motor 33 to provide power and signal control. Because the area attachment of the functional panel 61 contains only some of the functional assemblies and the power supply control assembly, the functional panel 61 is relatively narrow, and when installed in a parking space, the flap 41 is positioned further outward, drawing attention to the left and right when using the lock. Furthermore, the light bar 62 also serves as a warning function at night, and the display assembly installed on the functional panel 61 uses a human body detection sensor 67 to identify the area and outputs a warning sound from the voice horn 66 when a person approaches. This improves the operational safety of the equipment.

[0037] As shown in Figures 1, 3, and 7, the detection module can sense the position of the vehicle relative to the flap lock plate in real time, and the power supply control assembly is electrically connected to the detection module to provide power and communication. Furthermore, the detection module includes an inspection plate 21, on which an ultrasonic probe 24 and a multimode detection module are mounted. One side of the inspection plate 21 is provided with slots and wire exit holes for mounting the ultrasonic probe 24 and the multimode detection module, and the other side is provided with reinforcing ribs and wire passage grooves. The ultrasonic probe 24 is assembled to the inspection plate 21 via a probe holder 22 in an engagement groove manner, and after the ultrasonic probe 24 is mounted, it becomes slightly higher than the inspection plate 21. The multimode detection module is assembled to the inspection plate 21 via a detection housing 23 in an engagement groove manner, and the multimode detection module employs radar and optical sensing detection and can work in cooperation with the ultrasonic probe 24 to achieve vehicle position detection. Furthermore, as shown in Figures 1 and 8, a flap detection sensor 42 is installed on the flap 41. This flap detection sensor 42 works in cooperation with the detection module to detect the vehicle's position, forming multiple detections, which has the advantages of a high detection rate and easy maintenance.

[0038] The entire device features a compact design, fitting within a 10cm asphalt layer. This improves ease of installation and reliability. At the same time, the design of the flap's one-sided axis fixing, which combines upper and lower semicircular shapes with screw fixing, allows for quick on-site maintenance and improves the efficiency of on-site maintenance work.

[0039] The operation process of the present invention: When the flap lock plate is activated, the motor 33 rotates the screw 35, causing the nut 34 to slide relative to the screw 35, thereby linking the links 77 on both sides of the nut 34 together. The two links 77 then rotate the two rocker arms 36 in correspondence, achieving angular rotation of the rotation shaft 37. One end of the rotation shaft 37 protrudes from the housing 32 and connects to the coupling 38, thereby linking and angularly rotating the flap 41 (flap shaft 45). As the flap shaft 45 rotates the flap 41, the other end of the flap 41 opens and closes relative to the bottom frame 11, and the organ cover 51 shields the cavity of the bottom frame 11. During the rotation of the flap 41 relative to the bottom frame 11, the telescopic bar 18 can be brought into close contact with the flap 41 by the action of the spring 75, thereby forming a dynamic seal in the gap.

[0040] When a vehicle enters a parking space, the detection module (ultrasonic probe 24, multimode detection module, and flap detection sensor 42) detects the vehicle's proximity and transmits a vehicle proximity signal. After receiving the vehicle proximity signal, the control panel module 13 controls the flap 41 to rise. If the flap 41 is in the raised position and the vehicle unintentionally moves away, the sensing bar 71 first contacts the vehicle chassis and transmits a contact signal to the control panel module 13 of the power supply control assembly. The power supply control assembly (control panel module 13) then controls the operation of the motor 33, driving the flap 41 to lower. By using elastic material for the main guard bar 43 and sub-guard bar 44, the tires and vehicle chassis can be effectively protected from damage. At the same time, the control panel module 13 controls the lowering angle of the flap 41 based on the angle signal from the angle encoder 73, preventing it from lowering completely and thus preventing non-payment of parking fees. The system can be configured to lower the baffle to a certain angle with a single instantaneous impact, or to drop the baffle at multiple angles. This prevents the baffle from getting caught on the chassis and prevents non-payment of fees by activating the stopper multiple times. Furthermore, the torsion spring 72 is used to provide an auxiliary force for the lift angle and to eliminate the gap between the transmission mechanism and the machining tolerance of the parts, thereby ensuring smooth raising and lowering of the flap 41.
