Description

Technical Field

[0001] The present invention relates to the field of intelligent flat-bed parking locks, and in particular to a ground-mounted intelligent flat-bed parking lock. Background Art

[0002] Smart flatbed parking locks are generally installed in public paid parking spaces on the road. After the vehicle is parked for more than the set free time, the flap rises to lock the vehicle. The owner can use WeChat or Alipay to identify the QR code on the lock body to pay by himself and unlock it before driving away safely. The use of smart flatbed parking locks can charge fees during the entire charging period, so as to collect all fees that should be collected and effectively reduce the rate of fee evasion.

[0003] Existing parking locks have the following defects:

[0004] 1. In order to prevent the flap from falling and escaping the fee, the current parking locks mostly use worm gear self-locking transmission mechanisms. In this regard, Chinese patent CN118600899A proposes that the driving block drives one end of the connecting arm to move, and at the same time, one end of the connecting arm rotates relative to the driving block, so that the other end of the connecting arm drives the flap to rotate around the rotation axis at the flap driving axis. This is to achieve a smaller volume mechanism, thereby reducing the size of the movement. However, when the flap is hit, the driving block is subjected to unidirectional force, and the mechanism is easily stuck and damaged. Therefore, a mechanism with a more stable force is needed, so that the parking lock disclosed in the patent still has problems.

[0005] 2. In poor light or at night, when the driver parks at the target parking space, especially in a parking lot or street parking space equipped with a parking lock, it is difficult to see the locking state of the parking lock. If the driver mistakenly enters a parking space where the parking lock bracket is in the upright locked state, the vehicle will be scratched and the parking lock will be damaged. In order to solve the above problems, Chinese patent CN221345374U provides a ground-mounted smart parking lock to address the shortcomings of the above-mentioned prior art, so that the parking lock can be disabled and enabled without human operation. The configured angle sensor and warning light strip can respectively monitor the opening and closing state of the limit plate in real time and display different warning colors accordingly, thereby providing interactive linkage for smart parking or roadside parking projects. However, there are still the following problems: the warning light strip of the lock body is not easy to find during the day, which may easily lead to the driver not knowing the specific situation of the lock body, causing accidents and disputes, so a voice prompt function is required when the human body is close.

[0006] 3. When the flap is raised, if the vehicle starts accidentally, it is easy to scratch the chassis (or tire) of the vehicle, causing damage to the vehicle. In order to solve the above problems, Chinese patent CN109610377A connects the output end of the motor to the input end of the worm gear mechanism; the output end of the worm gear mechanism is connected to the input end of the magnetic coupling; the output end of the magnetic coupling is connected to the input end of the planetary reducer; the output end of the planetary reducer is connected to the baffle so that when the baffle is subjected to a torque exceeding the overload protection torque of the device, the magnetic coupling will overload and slip, thereby protecting the motor and other mechanical transmission structures. However, there are still the following problems: first, slipping can easily cause personnel to escape, and the magnetic coupling structure has a large space and high cost, so a more high-performance design is needed to solve this problem. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a ground-mounted intelligent flatbed parking lock with multiple detection functions, which can be used to detect when approaching, thereby improving the safety of equipment operation.

[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 for cooperating with the induction magnet to monitor the rotation angle of the flap 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 are installed on the flaps on both sides of the main protective strip, and a sensing strip is embedded in the main protective strip.

DETAILED DESCRIPTION

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

[0045] Example: As shown in the attached Figures 1 to 10 As shown, the ground-mounted intelligent flat parking lock includes a bottom frame 11, a battery module 12, a control panel module 13, a support column 14, an axle support base 15, an axle support cover 16, a coupling support seat 17, a telescopic strip 18, a cover plate 19, a wiring tube 20, an inspection plate 21, a probe bracket 22, a detection shell 23, an ultrasonic probe 24, a chassis cover 31, a chassis 32, a motor 33, a nut 34, a screw rod 35, a rocker arm 36, a rotating shaft 37, a coupling 38, and a flap. 41, flap detection sensor 42, main protection strip 43, auxiliary protection strip 44, flap shaft 45, accordion cover 51, function board 61, light bar 62, lamp cover 63, foam 64, solar panel 65, voice speaker 66, human body sensing sensor 67, QR code card 68, reinforcing rib 70, sensing strip 71, torsion spring 72, angle encoder 73, induction magnet 74, spring 75, U-shaped slide 76, connecting rod 77, transmission module, function module, detection module and sensing component.

[0046] Reference Figure 2 , 3 The bottom frame 11 is a rectangular cabin structure with extended edges around the cabin. The functional module is arranged on one side of the bottom frame 11, and the transmission module and the detection module are arranged on the other side of the bottom frame 11. Preferably, a plurality of support columns 14 are detachably installed in the bottom frame 11 along the vertical direction. When the flap 41 is closed relative to the bottom frame 11, the support columns 14 provide support for the flap 41. A plurality of fixing holes are provided at the bottom of the bottom frame 11, so that the bottom frame 11 can be fixed to the parking space by threaded connection.

[0047] like Figure 1 , 2As shown, the flap 41 is arranged in the middle of the bottom frame 11, one side of the flap 41 is supported on the bottom frame 11 through the flap shaft 45, and an accordion cover 51 is installed 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 drives the flap 41 to rotate, the other side of the flap 41 opens and closes relative to the bottom frame 11, and the accordion cover 51 is used to shield the inner cavity of the bottom frame 11. Cover plates 19 are fixedly arranged on the bottom frame 11 on both sides of the accordion cover 51, and the cover plates 19 serve to separate the flap 41 and the accordion cover 51 from the functional module, the transmission module and the detection module. Preferably, as Figure 8 As shown, a main protection strip 43 is installed on the side of the flap 41 away from the flap shaft 45, and auxiliary protection strips 44 are installed on the flaps 41 on both sides of the main protection strip 43. A sensing strip 71 is embedded in the main protection strip 43. The sensing strip 71, the main protection strip 43 and the auxiliary protection strip 44 are used as sensing components, which can contact-sensing 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, and the power supply control component (control board module 13) controls the motor 33 to work and drive the flap 41 to descend. Preferably, the main protection strip 43 and the auxiliary protection strip 44 are made of elastic material, which can effectively protect the tires and the vehicle chassis from being scratched.

[0048] Reference Figure 2 , 9 The transmission module includes a motor 33 and a transmission assembly driven by the motor. The transmission assembly includes a screw rod 35 driven by the motor 33 and a nut 34 mounted on the screw rod 35. Both sides of the nut 34 are rotatably connected to a connecting rod 77. The other end of each connecting rod 77 is rotatably connected to a rocker arm 36. The rocker arm 36 is stacked on the outside of the connecting rod 77 and clamped on the rotating shaft 37. The rotating shaft 37 is connected to the flap shaft 45 for transmission, and the transmission assembly (transmission module) is used to drive the flap shaft 45 to rotate. The double-link double-rocker arm design avoids the problem that the left and right torques are unbalanced when a single rocker arm and a single connecting rod are driven by a large torque, thereby generating insufficient torque or increasing the friction coefficient of the driving structure, causing component wear and other problems.

[0049] Furthermore, the transmission assembly and the motor 33 are both installed in the chassis 32, the chassis 32 is fixed in the bottom frame 11 (the chassis 32 is provided with mounting positions designed to match the bottom frame 11 on both sides), and the chassis cover 31 is installed on the top of the chassis 32, and the shaft 37 passes through the chassis 32 and is connected to the flap shaft 45 through the coupling 38. Preferably, the coupling 38 is supported in the bottom frame 11 through the coupling support seat 17, and at the same time, the end of the flap shaft 45 away from the coupling 38 is supported by the shaft support cover 16 and the shaft support base 15, and the shaft support cover 16 and the shaft support base 15 are assembled to form a shaft hole. Figure 8As shown, the end of the rotating shaft 37 installed on the shaft support base 15 is provided with an induction magnet 74, and the shaft support base 15 is also equipped with an angle encoder 73, which can cooperate 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, and usually it will not be completely lowered to prevent vehicles from maliciously evading payment. It can be set to drop a certain angle at an instant impact, and the action of the multi-angle baffle falling can prevent the baffle from getting stuck on the chassis, and maintain multiple blocking reminders to prevent evasion of fees.

[0050] like Figure 2 , 10 As shown, a gap is left between the side of the flap 41 close to the flap shaft 45 and the bottom frame 11, and a U-shaped slide groove 76 is inserted (preferably, the U-shaped slide groove 76 can be made of U-shaped channel steel). The back of the U-shaped slide groove 76 is fixed to the inner wall of the bottom frame 11, and the open side of the U-shaped slide groove 76 is slidably installed with a telescopic strip 18 through a spring 75. The telescopic strip 18 can be close to the flap 41, thereby forming a dynamic seal at the gap. Preferably, a wiring tube 20 is set below the U-shaped slide groove 76, and the wiring tube 20 facilitates the circuit wiring between the functional module and the transmission module and the detection module. Figure 2 , 3 As shown in FIG. 4 , a cover plate 19 is provided on the bottom frame 11 on both sides of the accordion cover 51 to protect the internal structure of the lock body when the lock body is in operation and to make it more durable in harsh environments.

[0051] Reference Figure 2 , 8 A torsion spring 72 is sleeved on one or both ends of the flap shaft 45, one end of the torsion spring 72 abuts against the flap 41, and the other end of the torsion spring 72 contacts a limit structure provided in the bottom frame 11. The torsion spring 72 is used to assist the lifting angle of the flap and eliminate the gap of the transmission mechanism and the processing tolerance of parts, so that the flap can be lifted and lowered smoothly.

[0052] like Figure 3 , 5 As shown in Figure 6, the functional module includes a prompt component, a solar component, a power supply control component and a functional board 61. The solar panel 65 is installed on the functional board 61 through a layer of foam 64. As a solar component, the solar component can charge the power supply control component. The prompt component includes a lampshade 63, a QR code sign 68 and a voice speaker 66 which are sequentially installed on the functional board 61, wherein a groove is opened on the functional board 61 at a position corresponding to the lampshade 63, and the light bar 62 is placed in the groove and covers the lampshade 63. The QR code sign 68 is installed in a corresponding slot opened on the functional board 61, and holes for installing the voice speaker 66 and the human body sensing sensor 67 are also opened on the functional board 61, and the human body sensing sensor 67 is electrically connected to the voice speaker 66. Preferably, as Figure 6As shown, a reinforcing rib 70 is provided on the back of the functional board 61. The power supply control assembly is provided below the functional board 61, and the power supply control assembly includes a battery module 12 and a control board module 13, as shown in FIG. Figure 4 As shown, a number of support columns 14 are also provided below the position where the function board 61 is installed to facilitate support and avoid crushing the power supply control component. The power supply control component is electrically connected to the prompt component and the motor 33 to realize power supply and signal control. Since there are only some functional components and power supply control components in the area of ​​the function board 61, the function board 61 is relatively narrow, so that the flap 41 is closer to the outside when the function board 61 is installed on the parking space, which can be used to provide a clear reminder when the lock body is in use. The light bar 62 also has the function of providing a clear reminder at night. The reminder component provided on the function board 61 can perform regional recognition through the human body sensing sensor 67 when a human body approaches, thereby transmitting the signal to the voice speaker 66 to achieve an auxiliary reminder function, thereby improving the safety of equipment operation.

[0053] like Figure 1 , 3 As shown in , 7, the detection module can sense the position of the vehicle relative to the parking lock in real time, and the power supply control component is electrically connected to the detection module to realize power supply and communication. Furthermore, the detection module includes an inspection plate 21, on which an ultrasonic probe 24 and a multi-mode detection module are installed. One side of the inspection plate 21 is provided with a slot and a wire outlet for installing the ultrasonic probe 24 and the multi-mode detection module, and the other side is provided with reinforcing ribs and wire grooves. The ultrasonic probe 24 is assembled with the inspection plate 21 by means of a probe bracket 22. After installation, the ultrasonic probe 24 is higher than the inspection plate 21. The multi-mode detection module is assembled with the inspection plate 21 by means of a detection housing 23. The multi-mode detection module adopts radar and light sensing detection, and can cooperate with the ultrasonic probe 24 to realize vehicle position detection. In addition, as Figure 1 , 8 As shown, a flap detection sensor 42 is provided on the flap 41, and the flap detection sensor 42 can cooperate with the detection module to realize vehicle position detection, forming multiple detections, and has the advantages of high detection rate and more convenient maintenance.

[0054] The device of the present invention adopts a compact design as a whole, and the height dimension is controlled within the thickness range of the 10CM asphalt layer, which improves the convenience and reliability of installation. At the same time, the shaft fixation on one side of the flap adopts an upper and lower semicircular + screw fixing design, which provides the convenience of quick disassembly for on-site maintenance and improves the on-site operation and maintenance efficiency.

[0055] Working process of the present invention:

[0056] When the parking lock is working, the motor 33 drives the screw rod 35 to rotate, and the nut 34 slides relatively along the screw rod 35, thereby driving the connecting rods 77 on both sides of the nut 34, and then using the two connecting rods 77 to correspondingly drive the two rocker arms 36 to rotate, so as to realize the angular rotation of the rotating shaft 37. One end of the rotating shaft 37 protrudes from the chassis 32 and is connected to the coupling 38, thereby driving the flap 41 (flap shaft 45) to form an angular rotation. 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 accordion cover 51 is used to block 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 be pressed against 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 of the vehicle and sends a vehicle approach signal. After receiving the vehicle approach signal, the control panel module 13 controls the flap 41 to rise. When the flap 41 is in the raised state and the vehicle accidentally drives out, the sensing strip 71 first contacts the vehicle chassis and sends the contact signal to the control panel module 13 of the power supply control component. The power supply control component (control panel module 13) controls the motor 33 to work and drive the flap 41 to lower. The main protection strip 43 and the auxiliary protection strip 44 are made of elastic materials, which can effectively protect the tires and the vehicle chassis from being scratched. At the same time, the control panel module 13 controls the lowering angle of the flap 41 according to the angle signal of the angle encoder 73, and it usually does not completely lower, preventing the vehicle from maliciously evading payment. It can be set to drop a certain angle at an instant impact. The action of the multi-angle baffle falling can prevent the baffle from getting stuck on the chassis and maintain multiple blocking reminders to prevent evasion of fees. In addition, the torsion spring 72 is used to assist the lifting angle of the plate and eliminate the gap between the transmission mechanism and the processing tolerance of parts, so that the flap 41 can be raised and lowered smoothly.

[0058] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the claims attached to the present invention.
