Description

Technical Field

[0001] This utility model belongs to the field of parking space technology, specifically relating to a parking space locking device based on inductive loop and millimeter-wave radar detection. Background Technology

[0002] "Parking difficulties" have become a common problem in bustling urban areas. Drivers cannot know the availability of roadside parking spaces in advance, and can only blindly search for empty parking spaces after arriving at their destination. They cannot obtain information about available parking spaces in advance or reserve them in advance, which wastes too much time and energy on parking. To address this, our company has designed and proposed a parking space locking device based on inductive loop and millimeter-wave radar detection. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that cannot obtain information on available parking spaces, and to propose a parking space locking device based on inductive loops and millimeter-wave radar. This device can remotely lock available parking spaces, allowing for advance "reservation" of parking spaces and reducing the hassle of blindly searching for them.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a parking space locking device based on inductive loop and millimeter-wave radar, including a housing, which is fixed to the parking space by a base at the bottom, and a lifting rod is rotatably connected to the housing. The housing is equipped with a drive mechanism for raising and lowering the lifting rod, and the drive mechanism is connected to a control circuit board inside the housing via wires.

[0005] It also includes: a ground induction coil, which is buried inside the edge of the parking space and connected to the control circuit board inside the housing via a wire; a millimeter-wave radar module, which is fixedly installed on the top of the housing and connected to the control circuit board. The control circuit board is equipped with a positioning module and a remote control module. The terminal app is wirelessly connected to the remote control module for remotely controlling the drive mechanism to raise the lifting rod.

[0006] Furthermore, the lifting rod is U-shaped and rotatably mounted on the outside of the housing. The rotating end of the lifting rod is fixedly provided with a rotating shaft, which is rotatably connected to the housing and connected to the drive mechanism.

[0007] Furthermore, the drive mechanism includes a geared motor, which is fixedly installed inside the housing. A worm is fixedly installed on the output shaft of the geared motor, and a worm wheel adapted to the worm is fixedly installed on the rotating shaft. The worm wheel meshes with the worm.

[0008] Furthermore, a protective plate is provided on the side of the lifting rod away from the parking space. The two ends of the protective plate are movably connected to the top of the U-shaped lifting rod. A touch switch is fixedly provided below the protective plate and on the lifting rod. The touch switch is connected to the control circuit board through a wire.

[0009] Furthermore, the two ends of the guard plate are fixedly provided with T-shaped optical shafts, and the top two ends of the lifting rod are provided with bushings adapted to the T-shaped optical shafts. The T-shaped optical shafts are inserted into the bushings, and the bushings are also provided with springs for elastically supporting the T-shaped optical shafts.

[0010] The present invention proposes a parking space locking device based on inductive loop and millimeter-wave radar. The advantages are as follows: When parking is needed, the user can check the parking space status on a mobile app and remotely control the raising and lowering of the barrier to lock the parking space, thus reserving a space. Upon arrival at the parking space, the user can control the lowering of the barrier to park. Furthermore, by combining inductive loop and millimeter-wave radar, the present invention effectively senses and identifies vehicles in the parking space, improving the accuracy of vehicle identification.

[0015] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] Example 1 See Figures 1-4A parking space locking device based on inductive loop and millimeter-wave radar includes a housing 1, which is fixed to a parking space 7 by a base 11 at the bottom. A lifting rod 2, which is U-shaped, is rotatably connected to the housing 1 and is rotatably disposed on the outside of the housing 1. A rotating shaft 3 is fixedly disposed at the rotating end of the lifting rod 2, and the rotating shaft 3 passes through the housing 1 and is rotatably connected to the housing 1. A bushing or bearing is provided between the housing 1 and the rotating shaft 3 to facilitate better rotation of the rotating shaft 3. In order to realize the raising and lowering of the lifting rod 2, a drive mechanism for raising and lowering the lifting rod 2 is provided inside the housing 1. The drive mechanism is connected to the housing 1 via a wire. The control circuit board 12 includes a drive mechanism comprising a geared motor 4, which is fixedly mounted inside the housing 1. A worm gear 41 is fixedly mounted on the output shaft of the geared motor 4, and a worm wheel 31 adapted to the worm gear 41 is fixedly mounted on the rotating shaft 3. The worm wheel 31 meshes with the worm gear 41. Through the forward or reverse rotation of the geared motor 4, the rotating shaft 3 rotates clockwise or counterclockwise under the transmission of the worm gear 41 and the worm wheel 31, thereby realizing the raising and lowering of the lifting rod 2. The forward or reverse rotation of the geared motor 4 is controlled by the control circuit board 12, which contains a drive module for driving the geared motor 4 to rotate forward and backward.

[0017] It also includes: an inductive loop 6, which is embedded inside the edge of the parking space 7 and connected to a control circuit board 12 inside the housing 1 via wires. The control circuit board 12 is equipped with a detector for collecting the inductance of the inductive loop 6. The inductive loop 6 is used to sense when a vehicle enters or leaves the parking space. When a vehicle enters, leaves, or stays in the parking space, it changes the magnetic flux in the inductive loop 6, causing a change in the inductance of the inductive loop 6 circuit. The detector determines the vehicle status in the parking space by detecting this change in inductance. A millimeter-wave radar module 5 is fixedly installed on the top of the housing 1 and connected to the control circuit board 12. The millimeter-wave radar module 5 can detect the vehicle status in the parking space in real time, forming a dual-sensing mode with the inductive loop 6 to improve the accuracy of vehicle detection in the parking space. To protect the millimeter-wave radar module 5, a groove 13 is provided on the top of the housing 1, and the millimeter-wave radar module 5 is located in the groove 13. A protective cover for protecting the millimeter-wave radar module 5 is provided on the groove 13.

[0018] The control circuit board 12 is equipped with a positioning module and a remote control module. The positioning module uses a GPS positioning module or a Beidou positioning module to locate the parking space on the map. The terminal app is connected to the remote control module wirelessly to remotely control the drive mechanism to raise the lifting rod 2. The driver can view the destination and the status of nearby parking spaces on the mobile app, identify available parking spaces, and remotely lock them.

[0019] This utility model relates to a parking space locking device based on inductive loop and millimeter-wave radar. It can remotely lock vacant parking spaces, allowing for advance "reservation" of parking spaces and reducing the hassle of blindly searching for them. When parking is needed, the user can check the parking space status on a mobile device and remotely control the raising and lowering of the lifting gate 2 to lock the parking space via an app, thus "reserving" the space in advance. The parking space is timed and charged from the start of the reservation to prevent unauthorized occupation. Upon arrival at the parking space, the user controls the lowering of the lifting gate 2 via the app to unlock the space and park. During the process of entering, leaving, or parking, the device combines inductive loop 6 and millimeter-wave radar 5 to perform real-time sensing and identification of vehicles in the parking space, improving the accuracy of vehicle identification.

[0020] Example 2 Reference Figures 1-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a guard plate 21 is provided on the side of the lifting rod 2 away from the parking space 7. The two ends of the guard plate 21 are movably connected to the U-shaped top of the lifting rod 2. Below the guard plate 21 and on the lifting rod 2, a touch switch 25 is fixedly provided. The touch switch 25 is connected to the control circuit board 12 through wires. The setting of the guard plate 21 plays a protective role and can prevent accidental raising of the lifting rod 2 from damaging the vehicle. In order to make the guard plate 21 move smoothly, a T-shaped optical shaft 22 is fixedly provided at both ends of the guard plate 21. The top two ends of the lifting rod 2 are provided with bushings 23 that are adapted to the T-shaped optical shaft 22. The T-shaped optical shaft 22 is inserted into the bushing 23. The bushing 23 is also provided with a spring 24 for elastically supporting the T-shaped optical shaft 22. The guard plate 21 can move smoothly under the support of the T-shaped optical shaft 22 and can be reset under the action of the spring 24. When the lifting rod 2 is raised, if the guard plate 21 touches an obstacle, it will trigger the touch switch 25. At this time, the lifting rod 2 will be raised and automatically lowered, providing good protection.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
