Description

Technical Field

[0001] This utility model relates to the field of obstacle avoidance radar technology for unmanned aerial vehicles (UAVs), specifically a 360-degree omnidirectional obstacle avoidance radar steering system. Background Technology

[0002] Radar, short for "radio detection and ranging," is an electronic device that uses radio waves to detect targets and determine their spatial location. It is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate a target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and altitude.

[0003] To address the challenges posed by complex environments in the widespread application of drones across various industries, such as collisions with objects like trees, power lines, poles, and buildings, obstacle avoidance radar, such as lidar, ultrasonic radar, and millimeter-wave radar, is typically installed on drones to ensure safe flight in complex environments and to detect obstacles around the drone.

[0004] Currently, when drone obstacle avoidance radar is used, it can only detect and measure distances in a single direction or a few angles when measuring distances to surrounding obstacles. The obstacle avoidance effect is poor and its applicability is low. Moreover, in common obstacle avoidance radar applications, the structural design is complex, which is not conducive to disassembly and maintenance and has high costs. Utility Model Content

[0005] The purpose of this invention is to provide a 360-degree omnidirectional obstacle avoidance radar steering system. By using a directional narrow beam antenna in conjunction with a 360-degree steering gimbal, the obstacle avoidance radar can perform all-round, long-distance detection, thereby improving its detection range. By simplifying the steering structure and the overall installation structure, the system is highly modular, improving the overall size and volume, and also facilitating disassembly and maintenance.

[0006] This addresses the problems mentioned in the background technology regarding the poor obstacle avoidance performance, low applicability, and difficulty in disassembly and maintenance of UAV obstacle avoidance radar during the detection of surrounding obstacles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a 360-degree omnidirectional obstacle avoidance radar steering system, comprising a directional narrow beam antenna, an obstacle avoidance radar, and a steering gimbal. The upper end of the directional narrow beam antenna is secured by two screws, and an antenna mounting base is installed at the lower end of the directional narrow beam antenna. A pad is installed at the rear end of the directional narrow beam antenna, and the obstacle avoidance radar is located at the rear end of the pad. A radar bracket is located at the rear end of the obstacle avoidance radar, and a bracket mounting base is installed at the lower end of the radar bracket. The antenna mounting base and the bracket mounting base are mounted and fixed on a rotating platform. The rotating platform is fixed on the linkage shaft of the steering gimbal. The upper end of the steering gimbal has a rotor device, an inner motor is installed, and the lower end has a base.

[0008] Preferably, the radar bracket includes a fixing screw and a bracket fixing seat. The fixing screw is used for fixed connection between the obstacle avoidance radar and the radar bracket, and the bracket fixing seat is fixedly connected between the radar bracket and the rotating platform.

[0009] Preferably, the upper end of the linkage shaft is fixedly connected to the rotating platform, and the lower end is interlocked with the linkage plate and the motor shaft.

[0010] Preferably, the motor includes a rotating shaft, a motor housing, and a motor outlet. The rotating shaft faces the upper end of the motor and passes through the linkage plate and is rotatably connected to the motor. The motor housing is located at the lower end of the motor and is fixedly connected to the base by fasteners. The wires of the motor outlet are led out from one side of the notch connecting the motor to the base.

[0011] Preferably, the rotor device includes fixing screws and a wire inlet. Four sets of screws around the rotor device are fixedly connected to the linkage plate. The linkage plate is driven by the motor shaft, thereby driving the rotor device. The wire of the wire inlet is led out from the upper end inside the rotor device.

[0012] Preferably, the bottom of the steering gimbal has a base and a cable outlet. The base is fixedly connected by a screw, and the wire of the cable outlet is led out from the notch in the base.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: The 360-degree omnidirectional obstacle avoidance radar steering system features a reasonable structural design. By incorporating a directional narrow-beam antenna, the obstacle avoidance radar can perform all-around, long-range detection during rotation, improving its detection range applicability. The use of components such as pads, mounting bases, rotating platforms, and fixing screws provides cushioning, shock absorption, and protection for the obstacle avoidance radar during rotation driven by the steering gimbal. The rotor device, motor, linkage shaft, and linkage plate work together, and are assembled and fixed at the lower end of the steering gimbal with the base components, thus providing fixed installation and support for the motor. The motor's rotating shaft drives the linkage shaft and linkage plate, causing the linkage plate to drive the rotor device to rotate 360 ​​degrees, which in turn drives the obstacle avoidance radar to rotate omnidirectionally. This allows the obstacle avoidance radar to detect all surrounding angles, further improving its working efficiency. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-4This utility model provides a technical solution: a 360-degree omnidirectional obstacle avoidance radar steering system, including a directional narrow beam antenna 1, an obstacle avoidance radar 2, and a steering gimbal 3. The upper end of the directional narrow beam antenna 1 is mounted by two fixing studs 11, and the lower end of the directional narrow beam antenna 1 is mounted with an antenna mounting base 12. A pad 4 is mounted at the rear end of the directional narrow beam antenna 1, and the obstacle avoidance radar 2 is located at the rear end of the pad 4. The main function of the pad 4 is to buffer, dampen, and protect the obstacle avoidance radar 2 during its omnidirectional rotation. The radar 2 is mounted on a radar bracket 5 at its rear end. The bottom of the radar bracket 5 is mounted on a bracket fixing seat 52. The bracket fixing seat 52 is fixedly connected to the radar bracket 5 using fasteners. The antenna fixing seat 12 and the bracket fixing seat 52 are mounted on a rotating platform 6. The rotating platform 6 drives the directional narrow beam antenna 1 and the obstacle avoidance radar 2 to rotate in all directions. The rotating platform 6 is fixed on the linkage shaft 31. The upper end of the steering gimbal 3 has a rotor device 34, the inner end is mounted with a motor 33, the outer end has a gimbal shell 35, and the lower end is mounted with a base 36 and a cable outlet 37.

[0021] The radar bracket 5 includes a fixing screw 51 and a bracket fixing seat 52. The fixing screw 51 is fixedly connected between the obstacle avoidance radar 2 and the radar bracket 5. The fixing screw 51 has an insulating protective layer on the outside, which plays a protective and supporting role on the contact surface between the obstacle avoidance radar 2 and the radar bracket 5. The bracket fixing seat 52 is fixedly connected between the radar bracket 5 and the rotating platform 6 by fasteners. When the rotating platform 6 rotates 360 degrees, the bracket fixing seat 52 plays a supporting and stabilizing role for the obstacle avoidance radar 2.

[0022] The upper part of the linkage shaft 31 is fixedly connected to the rotating platform 6 by a nut, and the lower part of the linkage shaft 31 is interlocked with the linkage plate 32 and the rotating shaft 331 of the motor 33. When the nut on the upper part of the linkage shaft 31 is locked, the locking structure on the lower part of the linkage shaft 31 is locked synchronously.

[0023] The motor 33 includes a rotating shaft 331, a motor housing 332, and a motor outlet 333. The rotating shaft 331 passes through the linkage plate 32 and the linkage shaft 31 and is rotatably connected to the motor 33. The motor housing 332 is fixedly connected to the base 36 at the lower end of the motor by fastening screws. The wire of the motor outlet 333 is led out from the notch on the side where the motor 33 is connected to the base 36.

[0024] The rotor device 34 includes fixing screws 341 and a wire inlet 342. Four sets of fixing screws 341 are fixedly connected to the linkage plate 32 around the rotor device 34. The linkage plate 32 is driven by the motor shaft 331, thereby linking the rotor device 34. The wire of the wire inlet 342 is led out from the upper end inside the rotor device 34.

[0025] The base 36 is fixedly connected to the bottom of the steering gimbal 3 by fasteners, and the wire of the outlet 37 is led out from the notch of the base 36.

[0026] Working principle: First, the wires of outlet 37 and motor outlet 333 are connected. The user starts the motor 33 by switching on the power supply system. The rotating shaft 331 drives the linkage shaft 31 to rotate, which in turn drives the rotor device 34 on the upper end of the steering gimbal 3 to rotate. Thus, the rotor device 34, together with the linkage shaft 31 and the linkage device 32, drives the obstacle avoidance radar 2 on the rotating platform 6 to rotate 360 ​​degrees. At the same time, the directional narrow beam antenna 1 and the obstacle avoidance radar 2, together with the pad 3, provide buffering and shock absorption protection. Due to the structural design of the directional narrow beam antenna 1, the obstacle avoidance radar 2 can detect obstacles outward through the aperture of the directional narrow beam antenna 1, making it more applicable during omnidirectional rotation. Second, the speed of the rotating shaft 331 of the motor 33 can be controlled by the speed control wire of outlet 37. Finally, the directional narrow beam antenna 1, obstacle avoidance radar 2 and steering gimbal 3 are highly modular, with a simple structural design, making them easy to disassemble and maintain.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
