Description

Technical Field

[0001] The present invention relates to the technical field of millimeter-wave radar installation, and specifically, to a millimeter-wave radar installation device and method thereof. Background Art

[0002] Traffic millimeter-wave radar is a high-frequency and high-performance road-side sensor for accurately perceiving traffic conditions. It usually relies on millimeter-wave radar to comprehensively sense road conditions, traffic flow, safety events, etc. Thereby, it can output information such as the position, speed, and vehicle length of each target in real time, and continuously track data such as the running trajectory, real-time dynamic speed, running direction, and following distance of each vehicle. Through multi-radar networking and linkage, continuous tracking and positioning of the same target can be achieved. It is widely used in application scenarios such as high-speed real-time digital twin, vehicle-road coordination, autonomous driving, green highway, and intelligent highway management, enabling new infrastructure construction for intelligent highways.

[0003] The patent with the application number CN202123099121 discloses a radar installation device, including an adapter structure, a mounting structure, and a fixing structure. Among them, the adapter structure includes a first adapter plate and a second adapter plate arranged vertically. The mounting structure includes a mounting member, a first rotating member, and a first fastener. The first rotating member passes through the first adapter plate and the mounting member, so that the mounting member can rotate relative to the first adapter plate around the rotation axis of the first rotating member, and the mounting member and the first adapter plate can be fixed by using the first fastener. The fixing structure includes a fixing member, a second rotating member, and a second fastener. The second rotating member passes through the second adapter plate and the fixing member, so that the fixing member can rotate relative to the second adapter plate around the rotation axis of the second rotating member, and the fixing member and the second adapter plate can be fixed by using the second fastener. The central rotation axis of the second rotating member is perpendicular to the central rotation axis of the first rotating member, and thus two-direction adjustment can be achieved to meet the adjustment accuracy requirements.

[0004] It does achieve adjusting the installation angle and orientation of the lidar while keeping the lidar working stably through the rotating member and the fastener. However, since the radar usually needs to be installed at a high place, or serves as an infrastructure for highway management in some usage scenarios; in multi-radar networking, there are still problems such as the danger of high-altitude installation for installers and low installation efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a millimeter-wave radar installation device and method thereof to solve the problems raised in the above background art.

[0006] To achieve the above purpose, on the one hand, the present invention provides the following technical solution:

A cylindrical pin is vertically fixed at the outer end of the top of the rear side of the L-shaped clamping flap. Arc-shaped sliding rails for restricting the movement tracks of the two cylindrical pins are symmetrically opened in the middle of the upper section of the fixing plate. A number of springs are connected between the tops of the limiting flap and the fixing block on the same side. The concave piece and the convex piece are symmetrically arranged and are hinged through a hinge shaft at the symmetrical position;

[0010] A radar housing is installed between the two L-shaped clamping flaps. Bent groove pieces for mating and inserting the plugging convex blocks are arranged on the two side faces of the radar housing corresponding to the plugging convex blocks. Thick ropes for lifting the radar housing are connected to the radar housing corresponding to the flat holes at the top. The lower ends of the thick ropes are installed in the winch; A radar cover is installed on the front side of the radar housing, and a millimeter-wave radar is installed inside both of them; A thin rope for pulling down and controlling the flaring of the lower ends of a pair of limiting flaps is wound around the outside of the hinge shaft, so as to release the flipping of a pair of L-shaped clamping flaps to loosen the radar housing.

[0011] In the technical solution of the present invention, a vertical cantilever is fixedly arranged on the front side of the fixed rod through bolts. The bearing cylinders are fixedly installed on the front side of the vertical cantilever through bolts, and all the bearing cylinders are coaxially arranged; An extension rod is arranged at the top of the fixed rod, and a rain shelter for rain protection is arranged at the top of the extension rod.

[0012] In the technical solution of the present invention, a number of L-shaped rods are symmetrically arranged on the outer wall of the rotating rod. A number of thick pulleys arranged in a straight line for straightening the thick rope are rotatably connected to the L-shaped rods. At both sides of the upper end of the rotating rod, top pulleys for straightening the corresponding thick ropes are rotatably connected. The radar housing is in the shape of a rectangular block with an open front. The length of the thick rope is at least twice the length of the rotating rod. Both thick ropes are fixedly connected to the top surface of the radar housing through detachable bolts. A handle for easy gripping is provided at the front end of the angle control rod.

[0013] In the technical solution of the present invention, the rotating rod, the angle control rod, the front rod and the top rod are sequentially hinged end to end and enclose a shape of a parallelogram. A rotating ring is rotatably sleeved in the middle of the hinge shaft. The thin rope is fixedly connected to the lower end of the rotating ring. A fixing ring is connected to the lower end of the thin rope. At a lower position of the front rod, a lower convex block and an upper convex block for sleeving and fixing the fixing ring are fixedly provided.

[0015] In the technical solution of the present invention, the arc-shaped slide rail is in the shape of an arc curve, and the angle of its corresponding central angle is less than ninety degrees. Guide wheels for straightening the thick rope are rotatably connected to the upper edges of the fixing plate corresponding to the flat holes.

[0016] In the technical solution of the present invention, the rotation center of the L-shaped clamping flap is located at its turning point. One end of the L-shaped clamping flap close to the center of the fixing plate is a smooth arc-shaped curved surface edge for easy pressing and sliding.

[0017] In the technical solution of the present invention, the limit stop piece is in a block structure bent in the middle. Both limit stop pieces are located between the two fixing blocks. One end of the spring close to the hinge shaft is connected to the upper end of the limit stop piece. All the springs are at the same height and the spring is always in a stretched state. When the two L-shaped clamping flaps rotate, so that the corresponding cylindrical pins slide upward along the arc-shaped slide rail to the highest point, both cylindrical pins simultaneously enter between the two limit stop pieces, and the cylindrical pins on the same side correspondingly contact the limit stop pieces.

The concave piece and the convex piece are always symmetrical to each other.

[0019] On the other hand, the present invention also provides a method for installing a millimeter-wave radar. Using the above-mentioned millimeter-wave radar installation device, the method includes the following steps:

[0020] S1. First, the user needs to complete the installation and debugging of the millimeter-wave radar inside the radar housing, and install the radar cover on the radar housing through bolts;

[0024] S5. Rotate the rotating rod to make the winch tighten the thick rope, so as to lift the radar housing upward;

[0025] S6. After that, when the top surface of the radar housing contacts one end of the L-shaped clamping flap corresponding to the cylindrical pin and continues to move upward, the top surface of the radar housing gradually pushes the L-shaped clamping flap to rotate until the plugging convex block is plugged into the bent groove piece, and both cylindrical pins are clamped between the two limit retaining pieces, and the radar installation is completed;

[0026] S7. Subsequently, continue to control the up and down angle of the radar by adjusting the handle up and down until it is appropriate, and hold the handle and rotate along the rotating rod to adjust the left and right angle of the radar until it is appropriate.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. For the millimeter-wave radar installation device and its method, through the provided fixing plate, L-shaped clamping flap, plugging convex block, cylindrical pin and limit retaining piece, the radar housing can be lifted by the winch and thick rope at a low place. When the radar housing rises and touches the L-shaped clamping flap, it can cause the plugging convex block to rotate with the L-shaped clamping flap and insert into the bent groove piece, thereby clamping and fixing the radar housing; it realizes the ability to firmly install the radar at a high place by manual control at a low place without climbing, avoids the dangerous situation of installation workers climbing high, and improves the efficiency of installing high-altitude radars.

[0029] 2. For the millimeter-wave radar installation device and its method, through the limit retaining piece, fixed block, spring, concave piece, convex piece and thin rope arranged on the back of the fixing plate, after the plugging convex block is inserted into the bent groove piece to fix the radar housing, the L-shaped clamping flap can maintain the clamping state. Pulling the thin rope can drive the concave piece and convex piece to fold inwards downward so that the limit retaining piece releases the cylindrical pin, and the L-shaped clamping flap is relaxed synchronously, which is convenient for lowering and disassembling the radar.

[0030] 3. The millimeter-wave radar mounting device and its method achieve that the installer can control the angle orientation of the radar mounted on the top fixing plate only by manpower at the bottom through the parallelogram link structure formed by the set rotating rod, the angle control rod, the front rod, the top rod and the handle, which increases the flexibility of the mounting device and expands the coverage range of the millimeter-wave radar.

[0046] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figures 1 - 10 As shown, this embodiment provides a technical solution:

[0048] A millimeter-wave radar installation device includes a skeleton 1 and a clamp fixing device 2 arranged above the skeleton 1; the skeleton 1 includes a fixed platform 10 at the bottom, a fixed rod 11 vertically arranged on the top surface of the fixed platform 10, a plurality of bearing cylinders 13 fixedly arranged on the front side of the fixed rod 11, a rotating rod 14 rotatably inserted in the bearing cylinder 13, an angle control rod 15 hinged to the bottom end of the rotating rod 14, a front rod 16 hinged to the middle of the angle control rod 15, and the same top rod 17 hinged to the top ends of both the rotating rod 14 and the front rod 16. A winch 141 for controlling the millimeter-wave radar to move up and down along the rotating rod 14 is arranged at the bottom of the rotating rod 14, and a rotating rod 142 for controlling the lifting is also rotatably connected to one side of the winch 141.

[0049] The clamping and fixing device 2 includes a fixing plate 20 provided at the front end of the ejector rod 17, two symmetrically arranged L-shaped clamping flaps 21 rotatably connected to the front side of the fixing plate 20, two symmetrically arranged limiting flanges 22 rotatably connected to the rear side of the fixing plate 20, two symmetrically arranged fixing blocks 23 provided on the rear side of the fixing plate 20, a concave piece 24 hinged at the upper end of one of the limiting flanges 22, and a convex piece 25 hinged at the upper end of the other limiting flange 22. A flat hole 210 is provided at the center of the right-angled side section of the upper part of the L-shaped clamping flap 21. Plugging convex blocks 211 are fixedly provided on the opposite side surfaces of the two L-shaped clamping flaps 21. A cylindrical pin 212 is vertically fixed at the outer end of the top of the rear side of the L-shaped clamping flap 21. Arc-shaped slide rails 201 for restricting the movement tracks of the two cylindrical pins 212 are symmetrically provided in the middle of the upper section of the fixing plate 20. A plurality of springs 231 are connected between the tops of the limiting flanges 22 and the fixing blocks 23 on the same side. The concave piece 24 and the convex piece 25 are symmetrically arranged and are hinged at the symmetric position by a hinge shaft 26.

[0050] A radar housing 3 is installed between the two L-shaped clamping flaps 21. Bent groove pieces 30 for matingly inserting the plugging convex blocks 211 are provided on the two side surfaces of the radar housing 3 corresponding to the plugging convex blocks 211. Thick ropes 31 for lifting the radar housing 3 are connected to the radar housing 3 corresponding to the flat holes 210 at the top. The lower ends of the thick ropes 31 are installed in the winch 141. A radar cover 32 is installed on the front side of the radar housing 3, and a millimeter-wave radar is installed inside both of them. A thin rope 261 for pulling down to control the outward flaring of the lower ends of a pair of limiting flanges 22 is wound around the outer circumference of the hinge shaft 26, so as to release the flipping of a pair of L-shaped clamping flaps 21 to loosen the radar housing 3.

[0051] Preferably, a vertical cantilever 12 is fixedly provided on the front side of the fixed rod 11 by bolts. The bearing cylinder 13 is fixedly installed on the front side of the vertical cantilever 12 by bolts, and all the bearing cylinders 13 are coaxially arranged, so as to reserve a certain rotating space for the rotating rod 14 and other structures on the rotating rod 14. Thus, the radar housing 3 can rotate synchronously with the rotating rod 14 by a certain horizontal angle. In this embodiment, as Figure 1 shown in the figure, an extension rod 121 is provided at the top of the fixed rod 11, and a rain shelter 122 for rain protection is provided at the top of the extension rod 121.

[0052] Preferably, a number of L-shaped rods 143 are symmetrically arranged on the outer wall of the rotating rod 14. A number of thick pulleys 144 arranged in a straight line for straightening the thick rope 31 are rotatably connected to the L-shaped rods 143. Top pulleys 145 for straightening the corresponding thick ropes 31 are rotatably connected to both sides of the upper end of the rotating rod 14. The radar housing 3 is in the shape of a rectangular block with an open front. The length of the thick rope 31 is at least twice the length of the rotating rod 14. Both thick ropes 31 are fixedly connected to the top surface of the radar housing 3 through detachable bolts, so that the operator can install the thick rope 31 on the radar housing 3 at a lower position. A handle 150 convenient for holding is provided at the front end of the angle control rod 15.

[0053] Specifically, the rotating rod 14, the angle control rod 15, the front rod 16 and the top rod 17 are hinged end to end in sequence and enclose a shape of a parallelogram, so that the longitudinal angle of the radar installed at the top can be manually controlled at the bottom of the device through the parallelogram link structure. A rotating ring 260 is rotatably sleeved in the middle of the hinge shaft 26. The thin rope 261 is fixedly connected to the lower end of the rotating ring 260. A fixing ring 262 is connected to the lower end of the thin rope 261. A lower convex block 160 and an upper convex block 161 for sleeving and fixing the fixing ring 262 are fixedly arranged at a lower position of the front rod 16. Sleeving the fixing ring 262 on the lower convex block 160 or the upper convex block 161 can control the clamping degree of the clamping and fixing device 2 on the radar housing 3, and thus it is convenient to install or disassemble the radar housing 3 from the fixing plate 20.

[0054] Preferably, a number of thin pulleys 162 arranged in a straight line for straightening the thin rope 261 are rotatably connected to the outer wall of the front rod 16. A square hole 170 for passing the thin rope 261 is opened in the middle of the top rod 17 close to the front, so that the pulling force on the lower part of the thin rope 261 can be smoothly transmitted to the upper end of the thin rope 261.

[0055] It should be noted that the arc-shaped slide rail 201 is in the shape of an arc curve, and the angle of its corresponding central angle is less than ninety degrees. Thus, when lifting the radar housing 3, due to the action of gravity, the cylindrical pin 212 is located at the lower end of the arc-shaped slide rail 201, and one end of the L-shaped clamping flap 21 corresponding to the cylindrical pin 212 can first contact the top surface of the radar housing 3. When the radar housing 3 rises, the plugging convex block 211 will not hinder the rising of the radar housing 3. Guide wheels 203 for straightening the thick rope 31 are rotatably connected to the upper edge of the fixing plate 20 corresponding to the flat holes 210. Thus, the guide wheels 203 can lift the radar housing 3 with the thick rope 31 at a vertically upward angle.

[0056] Specifically, the rotation center of the L-shaped clamping flap 21 is located at its turning point. One end of the L-shaped clamping flap 21 close to the center of the fixing plate 20 is a smooth arc-shaped curved surface edge for easy pressing and sliding. Thus, when lifting the radar housing 3, the L-shaped clamping flap 21 can contact the radar housing 3 and be pushed by the radar housing 3 to gradually rotate until it completely fits and clamps the radar housing 3.

[0057] In this embodiment, the limit stopper 22 is a block-shaped structure with a bent middle portion, and the two limit stoppers 22 are located between the two fixed blocks 23. One end of the spring 231 close to the hinge shaft 26 is connected to the upper end of the limit stopper 22. All the springs 231 are at the same height, and the springs 231 are always in a stretched state, so that the concave piece 24, the convex piece 25 and all the springs 231 can be as Figure 6 and Figure 7 As shown in the figure, it can maintain a horizontal state without being subjected to other external forces, and thus the angle of the limit baffle 22 can also be temporarily fixed; when the two L-shaped clamping petals 21 rotate, so that the corresponding cylindrical pin 212 slides upward to the highest point along the arc slide rail 201, the two cylindrical pins 212 simultaneously enter between the two limit baffles 22, and the cylindrical pins 212 on the corresponding same side contact with the limit baffle 22, so that the cylindrical pin 212 can be limited and clamped by the limit baffle 22, so that the L-shaped clamping petals 21 can maintain a state of fitting and clamping the radar shell 3.

[0058] Specifically, a vertical slide groove 202 is opened at the center of the back side of the fixing plate 20, and a slider 240 is fixedly connected to the front end of the concave piece 24 at the coaxial position of the hinge shaft 26. The slider 240 is slidably connected to the vertical slide groove 202, so that when the thin rope 261 is pulled and the fixing ring 262 is sleeved on the lower protrusion 160, the slider 240 can slide vertically downward, so that the two limit baffles 22 rotate synchronously at the same angle, thereby loosening the two cylindrical pins 212 at the same time to facilitate the disassembly of the radar shell 3; the concave piece 24 and the protruding piece 25 are always symmetrical to each other.

[0059] The present invention also provides a millimeter wave radar installation method, using the above-mentioned millimeter wave radar installation device, comprising the following steps:

[0060] S1. First, the user needs to install and debug the millimeter-wave radar in the radar housing 3, and install the radar cover 32 on the radar housing 3 by bolts;

[0061] S2. Subsequently, two thick ropes 31 are fixed to the top surface of the radar housing 3 by bolts at the lower part of the device;

[0062] S3, then, ensure that the fixing ring 262 is sleeved on the upper protrusion 161, so that the spring 231, the concave piece 24 and the protruding piece 25 are all kept in a horizontal state, and then the two limit blocks 22 are limited to an angle that is convenient for receiving and clamping the cylindrical pin 212;

[0063] S4. Then, adjust the handle 150 so that the angle control rod 15 is in a horizontal state, so that the top rod 17 is in a horizontal state and the fixing plate 20 is in a vertical state, so as to lift the radar housing 3 vertically upward;

[0064] S5. Rotate the rotating rod 142 to wind up the thick rope 31 with the winch 141, so as to hoist the radar housing 3 upward.

[0065] S6. After that, the top surface of the radar housing 3 contacts one end of the L-shaped flap 21 corresponding to the cylindrical pin 212 and continues to move upward. Thus, the top surface of the radar housing 3 gradually pushes the L-shaped flap 21 to rotate until the plugging protrusion 211 is plugged into the bent groove piece 30. Thus, the radar housing 3 is clamped and fixed on the fixing plate 20, and both cylindrical pins 212 are clamped between the two limiting flanges 22, and the radar installation is completed.

[0066] S7. Subsequently, continue to control the up-and-down angle of the radar by the up-and-down adjustment handle 150 until it is appropriate, and hold the handle 150 to rotate along the rotating rod 14 to adjust the left-and-right angle of the radar until it is appropriate.
