Description

Technical Field

[0001] This utility model belongs to the field of gimbal vibration reduction devices for UAVs, specifically relating to a high-performance gimbal vibration reduction device for UAV lidar. Background Technology

[0002] LiDAR, capable of detecting distance, orientation, altitude, speed, etc., and characterized by high sensitivity, high resolution and strong anti-interference, is often used in fields such as environmental perception and surveying. To improve the versatility of LiDAR, it is often installed on the gimbal of UAVs.

[0003] Currently, existing lidar mounted on gimbals often vibrates due to motor vibrations, causing it to shake during the flight of the drone. Since lidar is often used while moving, the resulting vibrations affect the stability of the lidar detection data.

[0004] Therefore, in response to the problem that the existing high-performance gimbals used for drone LiDAR have poor vibration damping and cannot prevent the LiDAR from shaking due to motor vibration, the existing high-performance gimbal vibration damping devices for drone LiDAR are improved by adding a vibration damping platform between the gimbal mounting platform and the LiDAR to reduce the impact of wind direction. Utility Model Content

[0005] In order to overcome the problem that the existing high-performance gimbals used for drone lidar have poor vibration reduction and cannot avoid the lidar shaking due to motor vibration.

[0006] The technical solution of this utility model is as follows: a high-performance gimbal vibration damping device for UAV lidar, comprising a mounting platform, a support frame, a lidar, a vibration damping platform, a vibration damping ball, and a controller; the mounting platform is installed below the UAV, a support frame is provided below the mounting platform, the lidar is installed on the support frame, a vibration damping platform is provided below the mounting platform, a vibration damping ball is installed between the mounting platform and the vibration damping platform, a controller is installed below the vibration damping platform, and the support frame is movably connected to the bottom of the controller.

[0007] Preferably, a shock-absorbing platform is added to the existing high-performance gimbal used for UAV LiDAR. The shock-absorbing ball is made of a damping material with a certain degree of elasticity. Through its special structural design, it absorbs and disperses vibrations, improves the shock absorption effect of the gimbal, avoids the LiDAR from being affected by motor vibration, and ensures the stability of LiDAR detection data. The controller can turn the LiDAR on and off and control the LiDAR to change its angle. The support frame is used to fix the LiDAR.

[0008] Preferably, a mounting base is fixedly connected to the top of the controller. The mounting base is close to the bottom of the shock absorber. The mounting base has four anchoring holes. By passing screws through the anchoring holes, the mounting base can be installed on the bottom of the shock absorber.

[0009] Preferably, the controller has a first interface for connecting the drone's power supply and a second interface for connecting the lidar. The first interface is used to connect the drone's power supply to provide power to the controller, support frame, and lidar, while the second interface enables the controller to operate the lidar and the second motor.

[0010] As a preferred option, a storage slot is provided at the bottom of the controller, and a motor is installed in the storage slot. The storage slot hides the motor and protects it from being exposed.

[0011] Preferably, a first rotating shaft is fixedly connected to the support frame, and the first rotating shaft is fixedly connected to the output end of a first motor. The first motor drives the first rotating shaft to rotate, so that the support frame fixedly connected to the first rotating shaft can drive the lidar to rotate, thereby achieving the effect of changing the lateral angle of the lidar.

[0012] As a preferred option, the support frame has two opposite storage slots, and the second motor is installed in the second storage slot. The second storage slot hides the second motor, which can protect the second motor and prevent it from being exposed.

[0013] Preferably, a second rotating shaft is fixedly connected to the left and right sides of the lidar. The second rotating shaft is fixedly connected to the output end of the second motor. The second motor drives the second rotating shaft to rotate, thereby driving the lidar to rotate up and down, and vertically changing the angle of the lidar.

[0014] The beneficial effects of this utility model are:

[0015] 1. By adding a shock-absorbing platform to the existing high-performance gimbal used for UAV lidar, the shock-absorbing ball is made of a damping material with a certain elasticity. Its special structural design absorbs and disperses vibrations, improves the shock absorption effect of the gimbal, avoids the lidar from being affected by motor vibration, and ensures the stability of lidar detection data.

[0016] 2. Motor 1 drives the support frame to rotate left and right, and Motor 2 drives the lidar to rotate up and down, thereby changing the angle of the lidar and making it more flexible. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-6 This utility model provides an embodiment of a high-performance gimbal vibration damping device for a drone LiDAR 3, comprising a mounting platform 1, a support frame 2, a LiDAR 3, a vibration damping platform 4, a vibration damping ball 5, and a controller 6. The mounting platform 1 is installed below the drone, and the support frame 2 is provided below the mounting platform 1. The LiDAR 3 is installed on the support frame 2. The vibration damping platform 4 is provided below the mounting platform 1, and the vibration damping ball 5 is installed between the mounting platform 1 and the vibration damping platform 4. The controller 6 is installed below the vibration damping platform 4, and the support frame 2 is movably connected to the controller 6. By adding a vibration damping platform 4 to the existing high-performance gimbal for the drone LiDAR 3, the vibration damping ball 5 is made of a damping material with a certain elasticity. Through its special structural design, it absorbs and disperses vibrations, improves the vibration damping effect of the gimbal, avoids the LiDAR 3 being affected by motor vibration, and ensures the stability of the LiDAR 3's detection data. The controller 6 can turn the LiDAR 3 on and off and control the LiDAR 3 to change its angle. The support frame 2 is used to fix the LiDAR 3.

[0026] Please see Figures 2-4In this embodiment, a mounting base 7 is fixedly connected to the top of the controller 6. The mounting base 7 is close to the bottom of the shock-absorbing platform 4. The mounting base 7 has four anchoring holes 8. The controller 6 is provided with a first interface 9 for connecting the power supply of the UAV and a second interface 10 for connecting the lidar 3. By passing screws through the anchoring holes 8, the mounting base 7 can be installed on the bottom of the shock-absorbing platform 4. The first interface 9 is used to connect the power supply of the UAV to provide power to the controller 6, the support frame 2 and the lidar 3. The second interface 10 enables the controller 6 to control the lidar 3 and the second motor 15.

[0027] Please see Figure 4-Figure 6 In this embodiment, the controller 6 has a first storage slot 11 at its bottom, in which a first motor 12 is installed. A first rotating shaft 13 is fixedly connected to the support frame 2, and the first rotating shaft 13 is fixedly connected to the output end of the first motor 12. The support frame 2 has two second storage slots 14 facing each other, in which a second motor 15 is installed. Second rotating shafts 16 are fixedly connected to the left and right sides of the lidar 3, and the second rotating shafts 16 are fixedly connected to the output ends of the second motors 15. The first storage slot 11 carries the first motor 12... The concealment function protects the first motor 12 from being exposed. The first motor 12 drives the first rotating shaft 13 to rotate, which in turn drives the support frame 2, which is fixedly connected to the first rotating shaft 13, to rotate the lidar 3, thereby changing the horizontal angle of the lidar 3. The second storage slot 14 conceals the second motor 15, protecting it from being exposed. The second motor 15 drives the second rotating shaft 16 to rotate, which in turn drives the lidar 3 to rotate vertically, changing the angle of the lidar 3.

[0028] When working, the staff first inserts the shock-absorbing ball 5 into the mounting platform 1, then installs the mounting platform 1 on the drone, and places the mounting seat 7 tightly against the bottom of the shock-absorbing platform 4. The screws are passed through the anchoring holes 8 on the mounting seat 7 to fix the mounting seat 7 under the shock-absorbing platform 4. Then the shock-absorbing platform 4 is installed under the shock-absorbing platform 4. The power supply of the drone is connected to the first interface 9 of the controller 6, and then the lidar 3 is connected to the second interface 10 of the controller 6.

[0029] The drone is started and controlled by the remote controller. The remote controller then activates the lidar 3 using the controller 6. The drone emits a detection laser beam towards the target and compares the received target echo with the emitted signal. After appropriate processing by the controller 6, relevant target information is obtained. During flight, the shock-absorbing ball 5 absorbs and disperses vibrations, preventing the lidar 3 from shaking. Simultaneously, as needed for detection, the controller 6 controls motor 12, which drives shaft 13 and the support frame 2 fixed below shaft 13 to rotate laterally. The controller 6 also controls motor 15, which drives shaft 16 to rotate, thereby causing the lidar 3 to rotate up and down, thus changing the angle of the lidar 3.

[0030] Through the above steps, a shock-absorbing platform 4 is added to the existing high-performance gimbal used for the drone LiDAR 3. The shock-absorbing ball 5 is made of a damping material with a certain elasticity. Through its special structural design, it absorbs and disperses vibrations, improves the shock absorption effect of the gimbal, avoids the LiDAR 3 from being affected by motor vibration, and ensures the stability of the LiDAR 3 detection data. This solves the problem that the existing high-performance gimbal used for the drone LiDAR 3 has poor shock absorption effect and cannot avoid the LiDAR 3 from shaking due to motor vibration.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
