Description

Technical Field

[0001] This application belongs to the field of radar monitoring technology, and more specifically, it relates to a radar automatic angle adjustment mechanism and an integrated intelligent sensing and monitoring device using the radar automatic angle adjustment mechanism. Background Technology

[0002] In intelligent transportation, security monitoring, and vehicle-road cooperative systems, millimeter-wave radar and integrated intelligent sensing and monitoring equipment based on millimeter-wave radar are widely used in target detection, traffic statistics, and event early warning scenarios, serving as core equipment for achieving intelligent sensing. However, existing radar equipment has significant drawbacks: its high installation height and long distance make manual adjustment of the horizontal and vertical angles extremely difficult, with even minor deviations leading to severe shifts in radar coverage areas; during long-term operation, vibration, temperature deformation, and structural loosening can cause the angle to drift slowly, resulting in decreased detection accuracy and missed or false detections; after angle shifts, manual on-site maintenance is required, leading to high maintenance costs, slow response times, and an inability to achieve unattended operation. Furthermore, it does not support remote adjustment, automatic correction, or adaptive adjustment, making it difficult to dynamically optimize the angle based on road restrictions, width limitations, and target detection requirements. Therefore, the industry urgently needs an automatic, high-precision, and remotely controllable radar angle adjustment mechanism to solve these problems. Summary of the Invention

[0007] In one possible implementation, the vertical adjustment drive assembly includes a vertical adjustment drive motor, a vertical adjustment lead screw, and a vertical linkage slider. The vertical adjustment drive motor is fixedly installed at the bottom of the support frame. The lower end of the vertical adjustment lead screw is fixedly connected to the output shaft of the vertical adjustment drive motor. The vertical linkage slider is slidably installed on the support frame. The upper end of the vertical adjustment lead screw passes through the vertical linkage slider and is threadedly connected to the vertical linkage slider. The vertical linkage slider has symmetrically arranged linkage parts corresponding to the vertical adjustment slider. A first guide groove is formed on the inner sidewall of the vertical adjustment slider in the horizontal direction. The linkage part is inserted into the first guide groove and slides with the top and bottom surfaces of the first guide groove.

[0008] In one possible implementation, the support frame includes a support plate, a base, a central rod, and a top cover connected sequentially from bottom to top; the outer contour of the central rod is smaller than the outer contours of the base and the top cover; the first swing bracket is installed between the base and the top cover and located outside the central rod; the annular guide groove is formed on the top surface of the base and / or the bottom surface of the top cover; the vertical adjustment drive motor is fixedly installed inside the base; the vertical adjustment screw passes through the central rod from bottom to top; the upper end of the vertical adjustment screw is rotatably connected to the top cover; the vertical linkage slider is installed inside the central rod; the side wall of the central rod has a second guide groove that slides with the linkage part; the linkage part can move vertically along the second guide groove.

[0009] In one possible implementation, a support ring is detachably mounted on the top of the base, the support ring is fitted onto the outside of the central rod, and the annular guide groove is formed on the top surface of the support ring and is coaxially arranged with the support ring.

[0010] In one possible implementation, a horizontal adjustment limiting member is fixedly installed on the outer wall of the base.

[0013] Compared with the prior art, the solution shown in this application's embodiment of the radar automatic angle adjustment mechanism has two first swing brackets, symmetrically arranged on both sides of the support frame in the horizontal direction. Since the first swing brackets are slidably installed in the annular guide groove, and the axis of the annular guide groove is set in the vertical direction, the first swing brackets can rotate in the horizontal direction along the annular guide groove; and since the radar is installed on the first swing brackets, the radar can swing synchronously with the first swing brackets around the axis of the annular guide groove. The horizontal adjustment drive assembly simultaneously drives two first swing brackets to move closer or further apart along the annular guide groove via the horizontal adjustment slider.

[0015] Compared with the prior art, the integrated intelligent sensing and monitoring device of this application employs a radar automatic angle adjustment mechanism, in which two first swing brackets are symmetrically arranged on both sides of the support frame in the horizontal direction. Since the first swing brackets are slidably installed in the annular guide groove, and the axis of the annular guide groove is set in the vertical direction, the first swing brackets can rotate horizontally along the annular guide groove; and since the radar is installed on the first swing brackets, the radar can swing synchronously around the axis of the annular guide groove along with the first swing brackets. The horizontal adjustment drive assembly simultaneously drives two first swing brackets to move closer or further apart along the annular guide groove via the horizontal adjustment slider. When the horizontal adjustment drive assembly drives the horizontal adjustment slider to move along a set straight line, the two first guide inclined slides move synchronously with the horizontal adjustment slider. The groove wall of the first guide inclined slide applies a radial thrust along the first connecting shaft at the corresponding position, forcing the two first connecting shafts to move synchronously along the first guide inclined slide, thereby driving the two first swing brackets to slide synchronously along the annular guide groove. This enables the simultaneous automatic adjustment of the horizontal orientation angle of two radars and shortens the debugging and maintenance time. Furthermore, under the dual guiding and limiting effect of the annular guide groove and the first guide inclined groove, the accuracy of the radar's horizontal orientation angle is guaranteed.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figures 1 to 5 This application describes an automatic radar angle adjustment mechanism. The automatic radar angle adjustment mechanism includes: a support frame 1, a first swing bracket 2, a horizontal adjustment slider 3, and a horizontal adjustment drive assembly 4. The support frame 1 has an annular guide groove 101, the axis of which is vertical. The first swing bracket 2 is symmetrically arranged on both sides of the support frame 1 in the horizontal direction and is slidably installed within the annular guide groove 101. The radar 8 is mounted on the first swing bracket 2 and faces outward. The horizontal adjustment slider 3 has two first guide oblique slide grooves 301 symmetrically arranged around the center of the annular guide groove 101. The two first swing brackets 2 have first connecting shafts 201 corresponding to the first guide oblique slide grooves 301. The first connecting shafts 201 pass through the first guide oblique slide grooves 301 and can slide horizontally along the first guide oblique slide grooves 301. The horizontal adjustment drive assembly 4 is mounted on the support frame 1 and is used to drive the horizontal adjustment slider 3 to reciprocate in a straight line in the horizontal direction.

[0021] This embodiment provides an automatic radar angle adjustment mechanism. Compared with the prior art, the first swing bracket 2 has two components, symmetrically arranged on both sides of the support frame 1 in the horizontal direction. Since the first swing bracket 2 is slidably installed in the annular guide groove 101, and the axis of the annular guide groove 101 is set in the vertical direction, the first swing bracket 2 can rotate in the horizontal direction along the annular guide groove 101; and the radar 8 is installed on the first swing bracket 2, so the radar 8 can swing synchronously with the first swing bracket 2 around the axis of the annular guide groove 101. The horizontal adjustment drive assembly 4 simultaneously drives the two first swing brackets 2 to move closer or further apart along the annular guide groove 101 via the horizontal adjustment slider 3. When the horizontal adjustment drive assembly 4 drives the horizontal adjustment slider 3 to move along the set straight line, the two first guide inclined slide grooves 301 move synchronously with the horizontal adjustment slider 3. The groove wall of the first guide inclined slide groove 301 applies a radial thrust to the corresponding first connecting shaft 201, forcing the two first connecting shafts 201 to move synchronously along the first guide inclined slide groove 301, thereby driving the two first swing brackets 2 to slide synchronously along the annular guide groove 101. This enables the simultaneous automatic adjustment of the horizontal orientation angle of the two radars 8 and shortens the debugging and maintenance time. Furthermore, under the dual guiding and limiting effect of the annular guide groove 101 and the first guide inclined slide groove 301, the accuracy of the horizontal orientation angle of the radar 8 is guaranteed.

[0022] This mechanism, through the structure of the first guide inclined slide groove 301 and the annular guide groove 101, directly converts the linear motion of the horizontal adjusting slider 3 into the circumferential swing of the first swing bracket 2, eliminating the need for multi-stage gear transmission. This not only reduces the overall size of the mechanism but also reduces the angle adjustment error caused by transmission clearance.

[0023] In some embodiments, please refer to Figures 1 to 3The horizontal adjustment drive assembly 4 includes a horizontal adjustment drive motor 401 and a horizontal adjustment lead screw 402. The horizontal adjustment drive motor 401 is fixedly mounted on the support frame 1. One end of the horizontal adjustment lead screw 402 is fixedly connected to the output shaft of the horizontal adjustment drive motor 401. The horizontal adjustment lead screw 402 is arranged in a horizontal direction and is threadedly connected to the horizontal adjustment slider 3. In this embodiment, the horizontal adjustment drive motor 401 is a servo motor. The output shaft of the horizontal adjustment drive motor 401 is arranged in a horizontal direction and is directly opposite to the axis of symmetry of the two first guide inclined slides 301. One end of the horizontal adjustment lead screw 402 is fixedly connected to the output shaft of the horizontal adjustment drive motor 401, and the other end is threadedly connected to the horizontal adjustment slider 3. When the horizontal adjustment drive motor 401 is started, it drives the horizontal adjustment screw 402 to rotate around its own axis. Through the transmission action of the threaded pair, the rotational motion of the horizontal adjustment screw 402 is converted into the linear motion of the horizontal adjustment slider 3 along the axial direction of the horizontal adjustment screw 402. This drives the first connecting shaft 201, which is slidably installed in the first guide inclined groove 301, to complete the precise adjustment of its horizontal position. In turn, it drives the first swing bracket 2 to slide along the annular guide groove 101, ultimately achieving synchronous adjustment of the horizontal orientation angle of the two radars 8. The horizontal adjustment drive motor 401, as a power source, realizes the automatic adjustment of the horizontal orientation angle of the two radars 8.

[0024] It should be noted that the horizontal adjustment drive assembly 4 can also use a cylinder, electric push rod or hydraulic cylinder as a power source, and then output the power of the power source to the horizontal adjustment slider 3 through conventional mechanical transmission methods such as gear transmission, chain transmission or belt transmission.

[0025] In some embodiments, please refer to Figures 1 to 3 , Figure 6An automatic radar angle adjustment mechanism further includes a second swing bracket 5, a vertical adjustment slider 6, and a vertical adjustment drive assembly 7. The lower end of the second swing bracket 5 is hinged to the first swing bracket 2. The vertical adjustment slider 6 is slidably mounted on the first swing bracket 2 and has a degree of freedom to move in the vertical direction. A second guide inclined slide groove 601 is provided on the vertical adjustment slider 6. A second connecting shaft 501 is provided at the upper end of the second swing bracket 5. The second connecting shaft 501 passes through the second guide inclined slide groove 601 and can slide in the vertical direction along the second guide inclined slide groove 601. The vertical adjustment drive assembly 7 is mounted on the support frame 1 and is used to drive the vertical adjustment slider 6 to reciprocate in a straight line in the vertical direction. The radar 8 is mounted on the second swing bracket 5 and faces outward. In this embodiment, the vertical adjustment slider 6 is slidably mounted on the first swing bracket 2 in the vertical direction; the second guide oblique slide groove 601 is formed on the vertical adjustment slider 6 and is located outside the first swing bracket 2; the second guide oblique slide groove 601 is set at an angle to the vertical direction; the second swing bracket 5 is located outside the first swing bracket 2, the lower end of the second swing bracket 5 is hinged to the first swing bracket 2, and the upper end of the second swing bracket 5 is provided with a second connecting shaft 501 that slides with the second guide oblique slide groove 601. The vertical adjustment drive assembly 7 is mounted on the support frame 1, and the vertical adjustment drive assembly 7 is used to drive the vertical adjustment slider 6 to reciprocate in the vertical direction. Since the radar 8 is mounted on the second swing bracket 5, the radar 8 can move synchronously with the second swing bracket 5. During the movement of the vertical adjustment slider 6, the inner wall of the second guide inclined slide 601 pushes the second connecting shaft 501 to move along its inclined surface. Since the lower end of the second swing bracket 5 is hinged to the first swing bracket 2, the displacement of the second connecting shaft 501 will cause the second swing bracket 5 to rotate around the hinge point, thereby realizing the automatic adjustment of the vertical pitch angle of the radar 8. This structure converts the linear motion in the vertical direction into the angular rotation of the second swing bracket 5 through the transmission between the second guide inclined slide 601 and the second connecting shaft 501. The transmission chain is short and the motion transmission accuracy is high, which can realize high-precision adjustment of the pitch angle of the radar 8.

[0026] In some embodiments, please refer to Figure 3The vertical adjustment drive assembly 7 includes a vertical adjustment drive motor 701, a vertical adjustment lead screw 702, and a vertical linkage slider 703. The vertical adjustment drive motor 701 is fixedly installed at the bottom of the support frame 1. The lower end of the vertical adjustment lead screw 702 is fixedly connected to the output shaft of the vertical adjustment drive motor 701. The vertical linkage slider 703 is slidably installed on the support frame 1. The upper end of the vertical adjustment lead screw 702 passes through the vertical linkage slider 703 and is threadedly connected to the vertical linkage slider 703. The vertical linkage slider 703 is symmetrically provided with linkage parts 704 corresponding to the vertical adjustment slider 6. The inner sidewall of the vertical adjustment slider 6 is provided with a first guide groove 602 in the horizontal direction. The linkage part 704 is inserted into the first guide groove 602 and slides with the top and bottom surfaces of the first guide groove 602. In this embodiment, the vertical adjustment drive motor 701 is a servo motor. The vertical adjustment drive motor 701 is fixedly installed at the bottom of the support frame 1. The output shaft of the vertical adjustment drive motor 701 is arranged in the vertical direction and located at the center of the support frame 1. The vertical adjustment screw 702 is arranged in the vertical direction on the support frame 1. The lower end of the vertical adjustment screw 702 is fixedly connected to the output shaft of the vertical adjustment drive motor 701. The vertical linkage slider 703 is installed at the top of the support frame 1. The vertical linkage slider 703 can only slide in the vertical direction on the support frame 1. The vertical linkage slider 703 is located between two vertical adjustment sliders 6. The upper end of the vertical adjustment screw 702 is connected to the vertical linkage slider 703 by a thread. The vertical linkage slider 703 has symmetrically arranged linkage parts 704 that correspond one-to-one with the vertical adjustment slider 6. The inner sidewall of the vertical adjustment slider 6 has a first guide groove 602 that slides with the linkage part 704. Since the first guide groove 602 is arranged horizontally and the linkage part 704 slides with the top and bottom surfaces of the first guide groove 602, the linkage part 704 can only produce horizontal displacement relative to the vertical adjustment slider 6. When the vertical adjustment drive motor 701 is started, it can drive the vertical adjustment screw 702 to rotate through the output shaft. Through the threaded transmission between the vertical adjustment screw 702 and the vertical linkage slider 703, the rotational motion of the vertical adjustment screw 702 is converted into the vertical linear motion of the vertical linkage slider 703. Since the linkage part 704 is inserted into the first guide groove 602 of the vertical adjustment slider 6, when the vertical linkage slider 703 moves, it can push the vertical adjustment sliders 6 on both sides to move synchronously in the vertical direction through the linkage part 704. During the movement of the vertical adjustment slider 6, the inner wall of the second guide inclined groove 601 will push the second connecting shaft 501 to move along its inclined surface. Since the lower end of the second swing bracket 5 is hinged to the first swing bracket 2, the displacement of the second connecting shaft 501 will drive the second swing bracket 5 to rotate around the hinge point, thereby realizing the automatic adjustment of the vertical pitch angle of the radar 8.Meanwhile, the linkage 704 only slides horizontally within the first guide groove 602. When the horizontal adjustment drive assembly 4 drives the first swing bracket 2 to move along the annular guide groove 101, the first swing bracket 2 will drive the vertical adjustment slider 6 to move synchronously. Therefore, the two vertical adjustment sliders 6 can produce horizontal displacement relative to the vertical linkage slider 703 without being restricted by the structure of the vertical linkage slider 703. Thus, the horizontal and pitch angles of the radar 8 can be adjusted simultaneously, greatly improving work efficiency.

[0027] In some embodiments, please refer to Figure 2 and Figure 3The support frame 1 includes a support plate 102, a base 103, a central rod 104, and a top cover 105 connected sequentially from bottom to top. The outer contour of the central rod 104 is smaller than the outer contours of the base 103 and the top cover 105. The first swing bracket 2 is installed between the base 103 and the top cover 105 and is located outside the central rod 104. The annular guide groove 101 is opened on the top surface of the base 103 and / or the bottom surface of the top cover 105. The vertical adjustment drive motor 701 is fixedly installed inside the base 103. The vertical adjustment screw 702 passes through the central rod 104 from bottom to top. The upper end of the vertical adjustment screw 702 is rotatably connected to the top cover 105. The vertical linkage slider 703 is installed inside the central rod 104. The side wall of the central rod 104 is provided with a second guide groove 106 that slides with the linkage part 704. The linkage part 704 can move vertically along the second guide groove 106. In this embodiment, the support frame 1 includes a support plate 102, a base 103, a central rod 104, and a top cover 105, which are connected sequentially from bottom to top. The outer contours of the base 103 and the top cover 105 are larger than the outer contour of the central rod 104. The central rod 104 is installed at the center of the base 103 and the top cover 105. An annular guide groove 101 is formed on the top surface of the base 103 and the bottom surface of the top cover 105 (the annular guide groove 101 may also be formed only on the top surface of the base 103, with the upper end of the first swing bracket 2 slidingly engaged with the bottom surface of the top cover 105). The annular guide groove 101 is coaxial with the central rod 104 and located outside the central rod 104. The upper and lower ends of the first swing bracket 2 are embedded in the annular guide groove 101, which can constrain the movement trajectory of the first swing bracket 2, prevent it from deviating during swinging, and maintain the movement stability of the first swing bracket 2. A vertical adjustment drive motor 701 is fixedly installed inside the base 103. A vertical adjustment lead screw 702 is installed inside the central rod 104 and runs through the entire central rod 104 from bottom to top. The top of the vertical adjustment lead screw 702 is rotatably connected to the top cover 105. A limiting bearing 112, which is rotatably connected to the vertical adjustment lead screw 702, is fixedly installed on the top cover 105. Therefore, the top cover 105 and the vertical adjustment drive motor 701 support and limit the upper and lower ends of the vertical adjustment lead screw 702. A vertical linkage slider 703 is installed inside the central rod 104. A second guide groove 106 is provided on the side wall of the central rod 104, which slides with the linkage part 704. The top of the second guide groove 106 is open, so the vertical linkage slider 703 can be assembled onto the central rod 104 from top to bottom. Under the guidance and limitation of the second guide groove 106, the vertical linkage slider 703 can only move in the vertical direction, thereby avoiding the vertical linkage slider 703 from rotating around the axis of the central rod 104 on the central rod 104.

[0028] In some embodiments, please refer to Figure 3A support ring 107 is detachably mounted on the top of the base 103. The support ring 107 is fitted onto the outside of the central rod 104. An annular guide groove 101 is formed on the top surface of the support ring 107 and is coaxially arranged with the support ring 107. In this embodiment, the support ring 107 and the base 103 are separate structures. A countersunk hole for mounting the support ring 107 is formed on the top surface of the base 103. The support ring 107 and the base 103 can be fixedly connected by fasteners, or the outer contour of the support ring 107 and the countersunk hole can be connected by an interference fit. The annular guide groove 101 is formed on the top surface of the support ring 107 and is coaxially arranged with the support ring 107. When the annular guide groove 101 is worn, the support ring 107 can be directly repaired or replaced, thereby reducing maintenance costs.

[0029] In some embodiments, please refer to Figure 3 and Figure 7 A horizontal adjustment limiting member 108 is fixedly installed on the outer wall of the base 103. A third guide groove 109 is formed on the top surface of the horizontal adjustment limiting member 108. The third guide groove 109 is parallel to the movement direction of the horizontal adjustment slider 3. A third connecting shaft 302 is provided on the horizontal adjustment slider 3. The third connecting shaft 302 passes through the third guide groove 109 and can slide along the direction of the third guide groove 109. In this embodiment, the horizontal adjustment limiting member 108 is fixedly fastened to the outside of the base 103 by bolts. The third guide groove 109 is formed on the top surface of the horizontal adjustment limiting member 108, and the third connecting shaft 302 is fixedly installed on the bottom of the horizontal adjustment slider 3. The third connecting shaft 302 and the third guide groove 109 are in sliding engagement. The third guide groove 109 moves in the same direction as the horizontal adjusting slider 3, and both ends of the third guide groove 109 are closed structures in the length direction. When the horizontal adjusting slider 3 is adjusted in the horizontal direction, the third connecting shaft 302 slides synchronously along the third guide groove 109. Through the limiting constraint of the horizontal adjusting limit member 108, the movement stroke and movement direction of the horizontal adjusting slider 3 can be precisely limited, avoiding collision between the two first swing brackets 2 due to the excessive movement range of the horizontal adjusting slider 3, and ultimately improving the horizontal position adjustment accuracy and stability of the overall device.

[0030] In some embodiments, please refer to Figure 3The support plate 102 has an assembly hole 110 that extends from top to bottom through the support plate 102 and faces the base 103. The outer contour of the assembly hole 110 is larger than the outer contour of the vertical adjustment drive motor 701. In this embodiment, the assembly hole 110 extends vertically through the support plate 102, and the base 103 has a mounting hole for mounting the vertical adjustment drive motor 701. The assembly hole 110 corresponds to this mounting hole. Since the outer contour of the assembly hole 110 is larger than the outer contour of the vertical adjustment drive motor 701, the vertical adjustment drive motor 701 can be assembled into the mounting hole inside the base 103 through the assembly hole 110. Therefore, when disassembling and assembling the vertical adjustment drive motor 701, it is not necessary to disassemble and assemble the base 103 and the support plate 102, which greatly improves assembly efficiency. In order to automatically control the operation of the vertical adjustment drive motor 701, a vertical motor control module 705 is also installed in the base 103.

[0031] In some embodiments, please refer to Figure 3 The support frame 1 also includes a support frame 111, which is detachably mounted on the support plate 102. The support frame 111 has a cavity for mounting the horizontal adjustment drive motor 401. In this embodiment, the support frame 111 is fixedly mounted on the support plate 102 with screws. The support frame 111 is a frame structure, and the cavity for accommodating the horizontal adjustment motor provides support and protection for the horizontal adjustment drive motor 401. To automatically control the operation of the horizontal adjustment drive motor 401, a horizontal motor control module 403 is also installed inside the support frame 111. The horizontal motor control module 403 and the horizontal adjustment drive motor 401 are arranged vertically on the support frame 111, thus saving space occupied by the support frame 111 in the horizontal direction. The support frame 111 also has a cavity for accommodating the horizontal motor control module 403.

[0032] The present invention also provides an integrated intelligent sensing and monitoring device, which includes a radar automatic angle adjustment mechanism as described in any one of the above claims.

[0033] This embodiment provides an integrated intelligent sensing and monitoring device employing a radar automatic angle adjustment mechanism. Compared to existing technologies, the first swing bracket 2 consists of two units, symmetrically arranged on both sides of the support frame 1 in the horizontal direction. Since the first swing bracket 2 is slidably mounted within the annular guide groove 101, and the axis of the annular guide groove 101 is vertically oriented, the first swing bracket 2 can rotate horizontally along the annular guide groove 101. The radar 8 is mounted on the first swing bracket 2, so the radar 8 can swing synchronously around the axis of the annular guide groove 101 along with the first swing bracket 2. The horizontal adjustment drive assembly 4 simultaneously drives the two first swing brackets 2 to move closer or further apart along the annular guide groove 101 via the horizontal adjustment slider 3. When the horizontal adjustment drive assembly 4 drives the horizontal adjustment slider 3 to move along the set straight line, the two first guide inclined slide grooves 301 move synchronously with the horizontal adjustment slider 3. The groove wall of the first guide inclined slide groove 301 applies a radial thrust to the corresponding first connecting shaft 201, forcing the two first connecting shafts 201 to move synchronously along the first guide inclined slide groove 301, thereby driving the two first swing brackets 2 to slide synchronously along the annular guide groove 101. This achieves synchronous adjustment of the horizontal orientation angle of the two radars 8, greatly shortening the debugging and maintenance time. Furthermore, under the dual guiding and limiting effect of the annular guide groove 101 and the first guide inclined slide groove 301, the accuracy of the horizontal orientation angle of the radar 8 is guaranteed.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
