This device is usually used in paid parking, exclusive parking space management and other scenarios. This intelligent locking device not only improves the efficiency of parking space use, but also enhances the automation and intelligence level of parking management, providing convenience and safety for car owners and parking lot managers.

[0003] The radar magnetic side sensing parking space vehicle detection device is an advanced parking management device that integrates radar technology and geomagnetic induction technology, and is specifically used to detect the status of vehicles in side parking spaces. This device combines the high-precision dynamic monitoring capability of millimeter-wave radar and the static presence sensing capability of ground sensing coils, providing a more comprehensive and accurate detection method for side parking spaces. This composite detection device plays an important role in smart city construction, efficient parking management, and improving user experience, and is one of the key technologies in modern urban parking solutions.

Although it meets the use requirements to a certain extent, it is difficult to disassemble in actual use. The ground needs to be destroyed again, and it is relatively difficult to adjust or relocate the equipment, which is not convenient for flexible adjustment or temporary change of the parking lot layout.

[0025] A plurality of limiting bars 208 are fixedly installed inside the mounting block 201 , and the movable frame 204 is slidably installed on one side of the limiting bars 208 .

[0026] The specific implementation method is as follows: the gear 206 is driven to rotate by the self-locking knob 207, and then the gear 206 drives the toothed disc 202 to rotate. Under the cooperation of the slide groove 203 and the slide column 205, the movable frame 204 is displaced when the toothed disc 202 rotates, thereby changing the radius of the circle formed by the several movable frames 204. In the above manner, the movable frame 204 squeezes the inner wall of the mounting hole, and the outer cylinder 101 is fixedly installed inside the mounting hole by friction. In this process, the contact area between the main body mechanism 1 and the inner wall of the mounting hole is effectively increased by the rubber pad 209, thereby generating a stronger friction force, and the friction force between the rubber pad 209 and the inner wall of the mounting hole is further increased by the anti-slip pattern 210, thereby improving the fixing effect. When it is necessary to take it out, the self-locking knob 207 is rotated to reduce the diameter of the inner support mounting mechanism 2 to reduce the friction force between the rubber pad 209 and the inner wall of the mounting hole, and the outer cylinder 101 can be taken out.

[0029] A special-shaped hole 108 is provided at the top of the top tube 102 .

[0030] The specific implementation method is as follows: through the cooperation between the outer tube 101, the top tube 102, the inner tube 103, and the waterproof ring 104, a multi-layer waterproof mechanism is formed to effectively prevent water from entering the device. Through the non-contact detection capability of the radar sensor 106, it can penetrate rain, fog, dust, and is not affected by light, and accurately detect the approach, position and speed of the vehicle. At the same time, the geomagnetic sensor 105 senses the parking status of the vehicle by monitoring the changes in the ground magnetic field, and is particularly good at detecting static vehicles.

With the cooperation of the slide groove 203 and the slide column 205, the movable frame 204 is displaced when the toothed disc 202 rotates, thereby changing the radius of the circle formed by the movable frames 204. In this way, the movable frame 204 squeezes the inner wall of the mounting hole, and the outer cylinder 101 is fixedly installed inside the mounting hole by friction. In this process, the contact area between the main body mechanism 1 and the inner wall of the mounting hole is effectively increased by the rubber pad 209, generating a stronger friction force, and the friction force between the rubber pad 209 and the inner wall of the mounting hole is further increased by the anti-slip pattern 210, thereby improving the fixing effect. When it is necessary to take it out, the self-locking knob 207 is rotated to reduce the diameter of the inner support mounting mechanism 2, and the friction force between the rubber pad 209 and the inner wall of the mounting hole is reduced, so that the outer cylinder 101 can be taken out;

[0032] Through the cooperation among the outer tube 101, the top tube 102, the inner tube 103 and the waterproof ring 104, a multi-layer waterproof structure is formed to effectively prevent water from entering the device. Through the non-contact detection capability of the radar sensor 106, it can penetrate rain, fog, dust, and is not affected by light, and accurately detect the approach, position and speed of the vehicle.
