Description

Technical Field

[0001] This utility model belongs to the field of installation structure, specifically, it relates to a radar installation structure for traffic data collection. Background Technology

[0002] The radar mounting structure for traffic data acquisition is a hardware system design specifically designed to fix, support, and optimize the operating environment of radar equipment. Its core objective is to ensure that radar sensors can stably and efficiently acquire traffic flow data in complex road scenarios.

[0003] Chinese Patent No. CN222561768U discloses a radar sensor mounting structure for traffic detection, comprising: a sensor body, a base plate at the lower end of the sensor body, a mounting plate at the lower end of the base plate, a compression spring inside a first spring groove, slide bars on the inner walls of both sides of the first spring groove, a guide rod slidably connected inside the first spring groove, a sliding groove on both sides of the guide rod near the slide bar, and a locking block fixedly connected to one end of the guide rod, a circular groove at the upper end of the base plate, a plurality of positioning holes on the inner wall of the circular groove, a second spring groove at the lower end of the sensor body, a tension spring inside the second spring groove, and a positioning pin at the front end of the tension spring.

[0004] The radar sensor mounting structure for traffic detection disclosed in this application uses a positioning pin to engage with the inside of a positioning hole to complete angle adjustment. Although this structure allows direct rotation of the sensor body for angle adjustment, it is susceptible to rotational displacement due to vibration. In addition, the two locking blocks need to be stretched outward during installation and disassembly, making it difficult to install or disassemble the sensor body in some narrow or obstructed spaces.

[0007] A radar mounting structure for traffic data collection includes: a mounting plate, a connecting seat on the mounting plate, and a radar body placed on the upper surface of the connecting seat;

[0008] The lower part of the radar body has two sliding blocks that slide elastically. Each of the two blocks has a push post on its outer side.

[0010] Optionally, side grooves are provided on both sides of the slide, and side ears are provided on both sides of the slider. The side ears slide in the side grooves, and a spring is installed between the two side ears in the same side groove.

[0011] Optionally, a guide rod is installed between the two sides of the side groove, the side lug is slidably fitted on the periphery of the guide rod, and the spring is sleeved on the periphery of the guide rod.

[0012] Optionally, a receiving groove is provided on the upper side of the slide, and a sealing block is slidably fitted in the receiving groove. The receiving groove is located between two sliders.

The lower part of the adjustment groove passes through the receiving groove laterally. Both the receiving groove and the adjustment groove are located on the upper side of the slide. The thickness of the adjustment groove is greater than the thickness of the receiving groove. The receiving groove and the adjustment groove are arranged in a cross shape.

This reduces the probability of obstacles affecting the disassembly of the radar body. Combined with the elastic sliding of the slider, this improves the efficiency of radar body and connector installation and disassembly, reducing the complexity of manual operation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] As a core component of modern intelligent transportation systems, radar for traffic data collection directly impacts the accuracy of data acquisition and the efficiency of equipment maintenance due to the stability, adjustability, and ease of operation of its installation structure. Currently, these radars are mostly deployed along roadsides, bridges, and tunnel entrances to monitor traffic flow, speed, and vehicle type in real time, providing data support for traffic management. Existing technologies typically employ bolt-fixed or snap-fit ​​connections for radar installation, which, while providing basic fixation, have limitations in terms of installation / disassembly efficiency, angle adjustment flexibility, and long-term stability.

[0031] Traditional bolt-fixing structures connect the radar body to the mounting base via pre-embedded bolts, requiring multiple tightening operations with tools. This is cumbersome and time-consuming, especially in scenarios requiring frequent disassembly and maintenance, where efficiency is low. Furthermore, bolt connections offer limited adjustment capabilities for the mounting angle, typically necessitating additional rotating joints or adjustment brackets, complicating the structure and increasing manufacturing costs. Another common type is the snap-fit ​​mounting structure, which uses elastic claws that engage with base slots for quick assembly and disassembly, such as using spring steel sheets or plastic clips. However, these structures are prone to elastic failure due to material fatigue during long-term use, leading to loosening or even detachment. They also lack stability under vibration, making them unsuitable for the high-intensity, high-frequency mechanical load requirements of traffic scenarios.

[0032] Regarding angle adjustment, some existing technologies achieve multi-directional adjustment by using a spherical hinge or gear transmission mechanism between the radar body and the mounting base. For example, a spherical hinge structure allows the radar body to pitch or rotate within a certain range, but the locking mechanism often relies on friction or simple pins, resulting in low adjustment accuracy and susceptibility to external interference, affecting the consistency of data acquisition direction. While a gear transmission mechanism can fix the angle through the meshing of a rack and pinion, it usually requires separate operation of the adjustment knob or handle, separating it from the installation process and increasing operational complexity. Furthermore, in outdoor environments, the gears are susceptible to dust and rain corrosion, leading to poor meshing or rust and jamming.

[0033] To address post-installation stability issues, existing technologies often employ methods such as reinforcing ribs, multi-point fixing, or rubber pads for cushioning. For example, adding cross-shaped reinforcing ribs to the back of the mounting plate improves bending resistance, or placing rubber pads at the bottom of the connector to absorb vibrations generated by passing vehicles. However, while such designs improve overall rigidity, they do not fundamentally solve the problem of dynamic micro-displacement between the mounting structure and the radar body. Especially under long-term vibration, bolts may gradually loosen, and clips may undergo elastic deformation, leading to gaps between the radar body and the mounting base, affecting data acquisition accuracy.

[0034] In terms of dust and protection, outdoor radar installation structures need to cope with environmental factors such as dust and rain. Existing technologies sometimes use sealing rings or protective covers to enclose the connection points, such as placing an annular sealing ring at the joint between the radar body and the mounting base, or adding a removable plastic protective cover. However, sealing rings are prone to wear and aging during frequent disassembly and assembly, and protective covers may affect heat dissipation or increase the size of the radar body, limiting their applicability, especially in transportation facilities requiring compact layouts. Furthermore, traditional installation structures lack effective dustproof designs for internal moving parts (such as springs and sliders), allowing dust to easily penetrate the sliding tracks or elastic elements, leading to mechanism jamming or elastic failure.

[0035] In existing technologies, the application of elastic elements is mostly limited to simple compression springs or torsion springs, such as using springs to provide clamping force in snap-fit ​​structures. However, such designs typically lack a guiding mechanism, and the spring is prone to lateral bending or twisting during repeated compression, resulting in uneven distribution of elastic force and shortened service life. Some improvements involve adding a sleeve to the outside of the spring to limit its deformation direction, but friction between the sleeve and the spring may affect the smoothness of sliding, which is particularly difficult to meet the requirements in scenarios requiring high-precision displacement control.

[0036] In terms of ease of operation, the human-machine interface design of existing installation structures is relatively simple, such as using exposed wrench-type latches or locking mechanisms that require special tools for adjustment. Such designs are inconvenient to operate in rainy or low-temperature environments, and exposed parts are easily touched or damaged by human intervention. A few high-end devices use electric drive mechanisms to achieve automatic locking and angle adjustment, but they rely on external power supplies or built-in batteries, which face power supply stability issues during long-term outdoor use, and are also costly, making widespread application difficult.

[0037] In summary, existing radar installation structures for traffic data collection still have many shortcomings in terms of rapid assembly and disassembly, precise angle adjustment, environmental adaptability, and long-term stability. How to integrate installation and adjustment functions through structural optimization, simplify the operation process, and simultaneously improve vibration resistance, dust resistance, and the reliability of elastic components has become an important direction for technological improvement in this field.

[0038] Please see Figure 1-4 As shown, this embodiment provides a radar installation structure for traffic data collection, including: a mounting plate 1, a connecting seat 101 on the mounting plate 1, and a radar body 2 placed on the upper surface of the connecting seat 101;

[0039] The lower part of the radar body 2 has two sliding blocks 3 that slide elastically. Each of the two sliding blocks 3 has a push post 304 on its outer side. The lower side of the sliding block 3 has a retaining plate 301. The side of the retaining plate 301 is equipped with an arc-shaped rack 302. The upper end face of the connecting seat 101 has an insertion groove 102. The lower end face of the insertion groove 102 has a limiting groove 103. The diameter of the limiting groove 103 is larger than the diameter of the insertion groove 102. The sliding block 3 passes vertically through the insertion groove 102. The retaining plate 301 is located in the limiting groove 103. The periphery of the limiting groove 103 is equipped with an internal gear ring 4. The arc-shaped rack 302 meshes with the inner wall side of the internal gear ring 4. The periphery of the radar body 2 is rotatably fitted with a rotating ring 5. The rotating ring 5 is located on the upper end face of the connecting seat 101. The inner wall side of the rotating ring 5 is equipped with an arc-shaped gradually shallowing groove 501 corresponding to the push post 304. The end of the push post 304 away from the sliding block 3 is located in the arc-shaped gradually shallowing groove 501.

[0040] One application of this embodiment is as follows: When disassembling the radar body 2, support the radar body 2 and manually rotate the rotating ring 5. At this time, the rotating ring 5 gradually squeezes the push column 304 using the arc-shaped gradually shallow groove 501, so that the two push columns 304 move closer to each other. The push column 304 slides and pushes the slider 3, the clamping plate 301 and the arc-shaped rack 302 to move synchronously, so that the arc-shaped rack 302 disengages from the inner gear ring 4. When the farthest distance between the two arc-shaped racks 302 is less than the diameter of the insertion groove 102, the radar body 2 can be lifted directly to pull the clamping plate 301 and the arc-shaped rack 302 out of the connecting seat 101. After releasing the rotating ring 5, the clamping plate 301 slides in the opposite direction under the action of elasticity to reset, thereby separating the radar body 2 from the connecting seat 101. Similarly, referring to the above operation, the radar body 2 can be locked on the connecting seat 101, and the angle of the radar body 2 can be adjusted arbitrarily during or after installation, and then the arc-shaped rack 302 is engaged and fixed with the inner gear ring 4. It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0041] The meshing relationship between the arc-shaped rack 302 and the internal gear ring 4 enables the rotation and locking of the clamping plate 301 within the limiting groove 103, improving the accuracy of the angle adjustment of the radar body 2. Furthermore, combining the installation and angle adjustment of the radar body 2 enhances its ease of use. The squeezing or releasing action of the push column 304 by the arc-shaped gradually shallow groove 501 on the inner wall of the rotating ring 5 facilitates the control of the sliding displacement of the slider 3, clamping plate 301, and arc-shaped rack 302 by rotating the rotating ring 5, reducing the probability of obstacles affecting the disassembly of the radar body 2. Simultaneously, combined with the elastic sliding of the slider 3, it improves the efficiency of installing and disassembling the radar body 2 and the connecting seat 101, reducing the complexity of manual operation.

[0042] like Figure 2-4 As shown, the lower end face of the radar body 2 in this embodiment is provided with a groove 201, and the upper part of the slider 3 slides elastically in the groove 201. The side of the radar body 2 is provided with two through holes 203 that are connected to the groove 201. The groove 201 is located between the two through holes 203. The push post 304 passes through the through hole 203 laterally. The push post 304 is guided by the through hole 203, which facilitates the push post 304 to move laterally and stably along the through hole 203, reduces the risk of offset when the push post 304 is engaged with the arc-shaped shallow groove 501, and ensures the reliability of locking and releasing actions.

[0043] like Figure 2-4 As shown, in this embodiment, the slide groove 201 has side grooves 202 on both sides, and the slider 3 has side ears 303 on both sides. The side ears 303 are slidably fitted in the side grooves 202. A spring 10 is installed between the two side ears 303 in the same side groove 202. The side groove 202 cooperates with the side ears 303 and the spring 10 to provide elastic restoring force for the slider 3, improve the stability of the slider 3 when sliding, and at the same time, the side groove 202 limits the side ears 303 to prevent the slider 3 from falling out of the slide groove 201.

[0044] like Figure 3 As shown, in this embodiment, a guide rod 9 is installed between the two sides of the side groove 202. The side lug 303 is slidably fitted on the periphery of the guide rod 9. The spring 10 is sleeved on the periphery of the guide rod 9. The side lug 303 slides along the guide rod 9 and the spring 10 is sleeved on the periphery of the guide rod 9, which facilitates the constraint of the extension and retraction direction of the spring 10 and improves the guiding performance and bending resistance of the spring 10.

[0045] like Figure 2 , 3As shown, in this embodiment, the upper side of the slide groove 201 is provided with a receiving groove 204, and a sealing block 6 is slidably fitted inside the receiving groove 204. The receiving groove 204 is located between two sliders 3. The radar body 2 is provided with a transverse adjustment groove 205, which penetrates the radar body 2. The lower part of the adjustment groove 205 transversely penetrates the receiving groove 204. Both the receiving groove 204 and the adjustment groove 205 are located on the upper side of the slide groove 201. The thickness of the adjustment groove 205 is greater than the thickness of the receiving groove 204. The receiving groove 204 and the adjustment groove 205 are arranged in a cross shape. An extension plate 601 is installed on the upper side of the sealing block 6, which is slidably fitted inside the adjustment groove 205. Plate 601 extends horizontally through adjustment groove 205. Two adjustment components corresponding to extension plate 601 are provided on the side of radar body 2. When radar body 2 is fixed for a long time, the adjustment components can be used to push extension plate 601 and sealing block 6 downward, so that sealing block 6 slides from storage groove 204 into slide groove 201. The sealing block 6 is used to block between two sliders 3, so as to prevent the sliders 3 from sliding and disassembling. Through the cooperation of adjustment components, the position and height of sealing block 6 can be adjusted, so that sealing block 6 can hinder the sliding of slider 3 and reduce the probability of radar body 2 being disassembled from connecting seat 101.

[0046] like Figure 2 As shown, the adjusting component in this embodiment includes two bolts 8, and two nut blocks 7 are provided on the side of the radar body 2. The nut blocks 7 are threadedly engaged with the circumference of the bolts 8. A circular plate 801 is provided on the lower end face of the bolts 8. The lower part of the bolts 8 and the circular plate 801 are rotatably engaged in the extension plate 601. Through the engagement of the bolts 8 and the nut blocks 7, and the rotatable connection between the circular plate 801 at the lower part of the bolts 8 and the extension plate 601, it is convenient to drive the extension plate 601 and the sealing block 6 to move up and down by rotating the bolts 8, thereby improving the convenience of the sealing operation.

[0047] like Figure 1-4 As shown, the radar body 2 of this embodiment is provided with two convex rings on its periphery, and the inner wall of the rotating ring 5 is provided with two annular grooves. The convex rings are located in the annular grooves, and the arc-shaped gradually shallow groove 501 is located between the upper and lower annular grooves. The convex rings and annular grooves cooperate to constrain the axial displacement of the rotating ring 5 relative to the radar body 2, improve the coaxiality of the rotating ring 5 when rotating, reduce the risk of misalignment during the cooperation of the arc-shaped gradually shallow groove 501 and the push column 304, and ensure the smoothness of the rotation action.

[0048] like Figure 1-4 As shown, the rotating ring 5 in this embodiment has several anti-slip textures on its side. These anti-slip textures are evenly distributed around the circumference of the rotating ring 5. The anti-slip textures help to increase the friction when manually rotating the rotating ring 5, improve the operating feel, reduce the risk of slipping, and ensure the effective transmission of rotational force.
