Description

Technical Field

[0001] This utility model relates to the technical field of parking space detection equipment, and in particular to a millimeter-wave radar device for parking space detection. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band for detection. Millimeter waves typically refer to the 30–300 GHz frequency range. It has a wide range of applications and can be used to detect parking spaces in parking lots.

[0003] A search revealed a Chinese patent with authorization announcement number CN214123147U, which discloses a millimeter-wave radar device for parking space detection. This device effectively reduces the probability of missed detections by reasonably arranging the radar positions. However, the radars in this device are all embedded in grooves. When a vehicle passes over a parking space lock, the parking space lock will vibrate. Since there is no fixing mechanism between the radar and the parking space lock, the radar is easy to detach from the groove. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a millimeter-wave radar device for parking space detection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A millimeter-wave radar device for parking space detection includes a parking space lock. The upper surface of the parking space lock has a mounting groove, and a housing is slidably connected within the mounting groove. The housing contains a millimeter-wave radar body. Two clearance grooves are symmetrically distributed at both ends of one side of the inner wall of the mounting groove. A locking groove is located on one side of the parking space lock and communicates with the two clearance grooves. Two fixing blocks are fixedly connected to one side of the housing, and both fixing blocks are embedded in their corresponding clearance grooves. Each of the two fixing blocks has a limiting groove on one side. Guide rods are fixedly connected between the inner walls of the two limiting grooves on both sides. Locking rods are slidably connected to the two guide rods and are embedded in their locking grooves.

[0007] As a further embodiment of this utility model, sliding grooves are provided on both sides of the inner wall of the mounting groove, and sliding plates are slidably connected in the two sliding grooves. The upper surface of the sliding plates is in contact with the lower surface of the box. Multiple first springs are fixedly connected to the bottom inner wall of the mounting groove. At this time, the first springs are in a stressed state, and the other end of the first springs is in contact with the lower surface of the sliding plates.

[0008] As a further embodiment of this utility model, a sliding rod is fixedly connected between the upper and lower inner walls of the two sliding grooves, and multiple sliding rods pass through the sliding plate and pass through the corresponding first spring, so that the first spring is sleeved on the sliding rod.

[0009] As a further embodiment of this utility model, two symmetrical threaded openings are provided on the bottom outer wall of the box body, and screws are threaded into both threaded openings, with the tops of the two screws passing through the bottom inner wall of the box body and threadedly connected to the millimeter-wave radar body.

[0010] As a further embodiment of this utility model, a second spring is fixedly connected to one side of the inner wall of the limiting groove, and the other end of the second spring is fixed to one side of the clamping rod.

[0011] As a further improvement of this utility model, reflective stickers are attached to both sides of the parking space lock.

[0012] As a further improvement of this utility model, the parking space lock is provided with multiple mounting holes for fixing the parking space lock, and the multiple mounting holes are symmetrically distributed at the four corners of the parking space lock.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the millimeter-wave radar body is installed in the box and the box is locked in the mounting groove. Therefore, even if the parking lock is vibrated when the vehicle passes by, the millimeter-wave radar body will not fall off due to the vibration. At the same time, if the millimeter-wave radar body is damaged, it can be quickly disassembled.

[0015] 2. In this utility model, the provided sliding plate and the first spring allow the first spring to release its elastic force when the box is removed, causing the sliding plate to move upward along the slide groove, thereby moving the box upward and popping the box out of the mounting groove, thus avoiding the situation where it is difficult to remove the box due to the small space in the mounting groove.

[0016] 3. In this utility model, the sliding rod can guide the slide plate as it slides in the groove, preventing it from shifting and getting stuck, which would prevent the box from being ejected from the mounting groove. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A millimeter-wave radar device for parking space detection includes a parking space lock 1. The upper surface of the parking space lock 1 has a mounting groove 4. A housing 5 is slidably connected within the mounting groove 4. A millimeter-wave radar body 12 is housed within the housing 5. Two clearance grooves 11 are symmetrically distributed at both ends of one side of the inner wall of the mounting groove 4 on one side. A slot 6 is provided on one side of the parking space lock 1, located at and connected to the two clearance grooves 11. Two fixing blocks 13 are bolted to one side of the housing 5, and both fixing blocks 13 are embedded into corresponding... Inside the clearance groove 11, there are limit grooves 17 on one side of each of the two fixing blocks 13. Guide rods 19 are welded between the inner walls of the two limit grooves 17. A locking rod 14 is slidably connected to the two guide rods 19 and is embedded in the locking groove 6. By installing the millimeter-wave radar body 12 in the box 5 and locking the box 5 in the mounting groove 4, even if the parking lock 1 is vibrated when the vehicle passes over it, the millimeter-wave radar body 12 will not fall off due to the vibration. At the same time, if the millimeter-wave radar body 12 is damaged, it can be quickly disassembled.

[0025] In this invention, sliding grooves 7 are provided on both inner walls of the mounting groove 4. Slide plates 9 are slidably connected within the two sliding grooves 7, with the upper surface of the slide plates 9 contacting the lower surface of the box 5. Multiple first springs 10 are welded to the bottom inner wall of the mounting groove 4. At this time, the first springs 10 are under tension, and their other ends contact the lower surface of the slide plates 9. Through the provided slide plates 9 and first springs 10, when the box 5 is removed, the first springs 10 release their elastic force, causing the slide plates 9 to move upwards along the sliding grooves 7, thereby moving the box 5 upwards and ejecting it from the mounting groove 4. This avoids the difficulty of removing the box 5 due to the small space within the mounting groove 4. Slide rods 8 are welded between the upper and lower inner walls of the two sliding grooves 7. Multiple slide rods 8 pass through the slide plates 9 and corresponding first springs 10, so that the first springs 10 are fitted onto the slide rods 8. Through the provided slide rods 8, the slide plates 9 are guided during their sliding within the sliding grooves 7, preventing deviation during sliding. In cases where the housing 5 becomes stuck and cannot be ejected from the mounting slot 4, two symmetrical threaded openings 15 are provided on the bottom outer wall of the housing 5. Each threaded opening 15 is threaded with a screw 16, and the tips of both screws 16 pass through the bottom inner wall of the housing 5 and are threaded into the millimeter-wave radar body 12. The threaded openings 15 and screws 16 secure the millimeter-wave radar body 12 inside the housing 5, preventing loosening. A second spring 18 is welded to one side of the inner wall of the limiting groove 17. The other end of the spring 18 is fixed to one side of the lever 14. The lever 14 can be tightly engaged in the slot 6 by the second spring 18. Reflective stickers 2 are attached to both sides of the parking space lock 1. The reflective stickers 2 can reflect light to remind the driver. The parking space lock 1 has multiple mounting holes 3 for fixing the parking space lock 1. The multiple mounting holes 3 are symmetrically distributed at the four corners of the parking space lock 1. The mounting holes 3 make it convenient for staff to install the parking space lock 1 in the parking space.

[0026] The use of this utility model involves the following steps:

[0027] S1: By installing the millimeter-wave radar body 12 inside the housing 5 and locking the housing 5 in the mounting slot 4, even if the parking lock 1 vibrates when the vehicle passes over the parking lock 1, the millimeter-wave radar body 12 will not fall off due to the vibration.

[0028] S2: If it is necessary to disassemble the millimeter-wave radar body 12, first pull the lever 14 to move it along the limiting groove 17. When the lever 14 disengages from the groove 6, the first spring 10 releases its elastic force to drive the slide plate 9 to slide upward along the slide groove 7, thereby driving the box 5 to move upward. The box 5 moves upward along the mounting groove 4, so that the box 5 protrudes out of the mounting groove 4, and the box 5 can be taken out.

[0029] S3: Then remove the two screws 16 on the bottom outer wall of the box 5 to remove the millimeter-wave radar body 12.

[0030] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
