Description

Technical Field

[0001] This utility model relates to the field of radar technology, specifically to a multi-directional adjustable radar device. Background Technology

[0002] In practical applications of radar systems, the support bracket, as a key structure supporting the radar body, directly affects the radar's detection performance and applicable range through its installation and adjustment performance. Traditional radar brackets generally adopt a fixed installation design, meaning the bracket is rigidly connected to the mounting foundation. Once installed, the radar's horizontal and vertical angles are fixed, making flexible adjustment impossible according to actual detection needs.

[0003] This fixed design has obvious limitations in certain scenarios: when the radar needs to expand its detection range, track targets in a specific direction, or when the radar beam deviates from the preset angle due to the tilt or vibration of the mounting base, the fixed bracket cannot be adjusted to correct the angle. It can only be adjusted by disassembling and reinstalling, which is not only cumbersome to operate, but also affects the continuous working efficiency of the radar.

[0004] Therefore, the inventors believe that solving the above-mentioned technical problems and designing a radar device that can achieve horizontal and large-angle pitch direction angle adjustment and has a reliable self-locking function is a technical problem that those skilled in the art urgently need to solve.

The technical solution is as follows: A multi-directional adjustable radar device includes: a fixed bracket, a radar body 150, a pitch adjustment plate 130, a horizontal rotation table 140, a first drive unit, and a second drive unit. The fixed bracket includes two vertically spaced side plates 110; The pitch adjustment plate 130 is located between two side plates 110; a first rotating shaft 185 is fixed on both sides of the pitch adjustment plate 130, and the first rotating shafts 185 on both sides of the pitch adjustment plate 130 are rotatably connected to the side plates 110 on the same side. A second rotating shaft 164 is coaxially fixed to the bottom of the horizontal rotary table 140; the horizontal rotary table 140 is rotatably connected to the pitch adjustment plate 130 through the second rotating shaft 164. The radar body 150 is fixed to the top surface of the horizontal rotating platform 140; The first drive unit is driven to the first rotating shaft 185 to drive the pitch adjustment plate 130 to rotate. The second drive unit is connected to the second rotating shaft 164 to drive the horizontal rotary table 140 to rotate.

[0015] In this embodiment, the first drive unit includes a first fixed base 181, a first shaft 183, a first worm 182, a first worm wheel 184, and a first motor 172; The first fixed base 181 and the first motor 172 are fixed at intervals on the side plate 110 at the same position on the same side; One end of the first shaft 183 is fixed on the main shaft of the first motor 172, and the other end of the first shaft 183 is rotatably connected to the first fixed seat 181. The first worm gear 182 is coaxially fixed on the first shaft 183; the first worm wheel 184 is coaxially fixed on the first rotating shaft 185; the first worm wheel 184 and the first worm gear 182 mesh and transmit power.

[0016] In this embodiment, the second drive unit includes a second fixed base 162, a second shaft 161, a second worm 163, a second worm wheel 165, and a second motor 171; The second fixed base 162 is fixed on the pitch adjustment plate 130 and located on the opposite side of the horizontal rotary table 140; the second motor 171 is fixed on the side plate 110; One end of the second shaft 161 is fixed on the main shaft of the second motor 171, and the other end of the second shaft 161 is rotatably connected to the second fixed seat 162. The second worm gear 163 is coaxially fixed on the second shaft 161; the second worm wheel 165 is coaxially fixed on the second rotating shaft 164; the second worm wheel 165 and the second worm gear 163 mesh and drive each other.

[0017] In this embodiment, the fixing bracket also includes a base plate 120, which is fixed to the bottom between two side plates 110; the base plate 120 is provided with fixing holes 121.

[0018] In this embodiment, a control system is also included, which is electrically connected to the first motor 172 and the second motor 171; and an angle sensor is also included to detect the rotation angle of the second rotating shaft 164 and the first rotating shaft 185.

[0019] This utility model provides a multi-directional adjustable radar device that uses two independent drive units to control the horizontal rotation and elevation angle adjustment respectively, enabling the radar body to perform multi-angle detection in three-dimensional space. The working method of this utility model is as follows: (1) Initialize positioning The device is fixed to the target mounting base through the fixing holes 121 on the base plate 120; then the first motor 172 and the second motor 171 are started to check whether each transmission component is operating normally and to confirm the initial position of the radar body 150.

[0020] (2) Horizontal angle adjustment When it is necessary to adjust the horizontal detection direction of the radar, the control system sends a drive signal to the second motor 171. The main shaft of the second motor 171 drives the second shaft 161 to rotate, and the coaxially fixed second worm gear 163 rotates accordingly. The second worm gear 163 meshes with the second worm wheel 165, transmitting the rotational motion to the coaxially fixed second rotating shaft 164. The second rotating shaft 164 drives the horizontal rotating table 140 and the radar body 150 on top to rotate around the vertical axis, thereby achieving horizontal adjustment.

[0021] The rotation angle of the second shaft 164 is monitored in real time by an angle sensor. When the target angle is reached, the second motor 171 stops running. Utilizing the self-locking property of the worm gear transmission (the worm can drive the worm wheel, but the worm wheel cannot drive the worm in the opposite direction), the current angle is automatically locked after the motor is powered off, without the need for an additional locking mechanism.

[0022] (3) Pitch angle adjustment When it is necessary to adjust the radar elevation detection angle, the control system sends a drive signal to the first motor 172.

[0023] The main shaft of the first motor 172 drives the first shaft 183 to rotate, and the first worm gear 182, which is fixed on the same axis, rotates accordingly. The first worm gear 182 meshes with the first worm wheel 184, transmitting the rotational motion to the first rotating shaft 185, which is fixed on the same axis. The first rotating shaft 185 drives the pitch adjustment plate 130, the horizontal rotating table 140 and the radar body 150 to rotate around the horizontal axis, thereby realizing the pitch angle adjustment.

[0024] The rotation angle of the first shaft 185 is monitored in real time by an angle sensor. When the target angle is reached, the first motor 172 stops running. Similar to the horizontal adjustment, the current pitch angle is maintained by utilizing the self-locking property of the worm gear transmission.

[0025] (4) Combined motion control When it is necessary to change the horizontal and pitch angles simultaneously, the control system can synchronously drive the first motor 172 and the second motor 171; after the target angle is adjusted, the position is maintained by relying on the self-locking characteristics of the worm gear, without the need for additional energy consumption.

[0026] The present invention provides a multi-directional adjustable radar device with the following advantages: The present invention is designed with two independent worm gear mechanisms, which can realize automatic horizontal and large-angle pitch adjustment of the radar respectively. The device has a compact structure and automatic locking capability, which solves the problem of unreliable locking of traditional adjustable brackets.
