Description

Technical Field

[0001] This utility model relates to the field of radar drone technology, and in particular to a multi-directional adjustable three-dimensional lidar drone support. Background Technology

[0002] With the continuous development of UAV technology and LiDAR systems, their applications in surveying, inspection, terrain modeling and other fields are becoming increasingly widespread. As an emerging technology, 3D LiDAR UAVs carry 3D LiDAR sensors on UAVs (usually multi-rotor or fixed-wing aircraft), enabling them to quickly scan the ground or objects in the air, thereby acquiring a large amount of high-precision 3D spatial coordinate information in real time. This data can be used to generate digital elevation models (DEMs), build 3D maps and realize applications such as real-scene modeling.

[0003] However, existing lidar drone brackets generally suffer from problems such as limited adjustment methods, poor installation adaptability, insufficient adjustment precision, and low automation, making it difficult to meet the multi-angle and multi-directional scanning needs in complex environments. Currently, most brackets only have single-direction adjustment capabilities and lack comprehensive adjustment functions for height, horizontal position, and angle, resulting in difficult equipment installation and poor adaptability. In addition, some structural designs are unreasonable, further affecting overall stability and usage efficiency.

[0004] Therefore, it is necessary to design a multi-directional adjustable three-dimensional lidar drone support to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of existing LiDAR drone brackets, such as limited adjustment methods, poor adaptability, low automation, difficulty in meeting the multi-angle scanning needs of complex environments, and unreasonable structural design affecting stability and efficiency, this utility model provides a multi-directional adjustable three-dimensional LiDAR drone bracket.

[0006] The technical implementation scheme of this utility model is as follows: a multi-directional adjustable three-dimensional laser radar drone bracket, including a support plate, a limiting plate, a base plate, an adjusting rod, a top plate, an electric slide rail, an electric slider, a connecting shaft, and a mounting plate. The left and right sides of the bottom of the support plate are slidably connected to the limiting plates. Adjusting rods are rotatably connected inside the two limiting plates. The base plate is threadedly connected to the two adjusting rods. The base plate is slidably connected to the limiting plates. The top plate is fixedly connected to the top of the support plate. An electric slide rail is fixedly connected to the top of the top plate. An electric slider is slidably connected to the electric slide rail. A connecting shaft is rotatably connected to the top of the electric slider. The mounting plate is fixedly connected to the top of the connecting shaft.

[0007] As a further preferred option, both the limiting plate and the base plate are provided with multiple threaded holes.

[0008] As a further preferred option, the mounting plate is made of aluminum alloy.

[0009] As a further preferred embodiment, it also includes a support shaft, a transmission gear, and a rack rod. The support shaft is fixedly connected to the center of the support plate, and the transmission gear is rotatably connected to the support shaft. The rack rods are fixedly connected to the upper sides of the two limiting plates at opposite ends. The rack rods mesh with the transmission gears and are slidably connected to the support plate.

[0010] As a further preferred embodiment, it also includes a mounting housing, a motor, and a spur gear set. The mounting housing is mounted on the front top of the electric slider, and the motor is fixedly connected inside the mounting housing. A spur gear set is connected between the output shaft of the motor and the connecting shaft.

[0011] As a further preferred option, the mounting housing is made of ABS engineering plastic.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model achieves height adjustment through the threaded connection between the adjusting rod and the base plate, improving installation adaptability; at the same time, it achieves precise horizontal positioning through the electric slide rail and electric slider, adapting to the application needs of different scenarios and having good application prospects.

[0013] 2. This utility model enables the two limiting plates to move synchronously through the cooperation of the support shaft, transmission gear and rack, ensuring the stability and balance of width adjustment; the gear and rack meshing improves the adjustment accuracy, enhances the load-bearing capacity and operating efficiency, and improves the practicality and reliability of the device.

[0014] 3. This utility model achieves automatic adjustment of the mounting plate angle by setting up a mounting shell, a motor and a spur gear set, with high adjustment accuracy and fast response speed; the motor power is transmitted to the connecting shaft through the spur gear set, driving the mounting plate to rotate; the mounting shell protects the internal components, improving structural stability and service life.

[0015] 4. The mounting plate of this utility model is made of aluminum alloy, which is lightweight and high-strength.

Detailed Implementation

[0022] Example: A multi-directional adjustable 3D LiDAR drone support, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a support plate 1, a limiting plate 2, a base plate 3, an adjusting rod 4, a top plate 5, an electric slide rail 6, an electric slider 7, a connecting shaft 8, and a mounting plate 9. The supporting plate 1 is slidably connected to the left and right sides of its bottom, and the limiting plates 2 are rotatably connected to the inside of each limiting plate 2. The base plate 3 is threadedly connected to each of the two adjusting rods 4. The base plate 3 is slidably connected to the limiting plates 2. The limiting plates 2 and the base plate 3 are provided with multiple threaded holes. The top plate 5 is installed on the top of the supporting plate 1 by screws. The electric slide rail 6 is installed on the top of the top plate 5 by screws. The electric slider 7 is slidably connected to the electric slide rail 6. The top of the electric slider 7 is rotatably connected to the connecting shaft 8. The top of the connecting shaft 8 is connected to the mounting plate 9 by welding. The mounting plate 9 is made of aluminum alloy.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a support shaft 10, a transmission gear 11, and a rack rod 12. The support shaft 10 is connected to the middle of the support plate 1 by welding. The transmission gear 11 is rotatably connected to the support shaft 10. The rack rod 12 is connected to the upper side of the two limiting plates 2 at opposite ends by welding. The rack rod 12 meshes with the transmission gear 11 and is slidably connected to the support plate 1.

[0024] like Figure 5 As shown, it also includes a mounting housing 13, a motor 14, and a spur gear set 15. The mounting housing 13 is installed on the front top of the electric slider 7. The mounting housing 13 is made of ABS engineering plastic. The motor 14 is installed inside the mounting housing 13 by screws. The output shaft of the motor 14 is connected to the connecting shaft 8 by a spur gear set 15.

[0025] When the device is needed, firstly, adjust the height and width according to the dimensions of the 3D LiDAR scanning equipment. Manually rotate the adjusting rod 4 to move the base plate 3 up and down along the rod 4, achieving precise height adjustment. Then, pull or push either of the limiting plates 2. The limiting plate 2 moves the rack 12, and because the rack 12 meshes with the transmission gear 11, the other limiting plate 2 moves synchronously in the opposite direction, thus achieving synchronous width adjustment between the two limiting plates 2, ensuring the balance and stability of the overall structure. After adjustment, use the multiple threaded holes on the limiting plates 2 and the base plate 3 to securely fix the entire bracket to the 3D LiDAR scanning equipment with screws. Next, install the UAV onto the mounting plate 9 and tighten it to prevent loosening during operation. Then, start the electric slide rail 6, controlling the electric slider 7 to slide along the electric slide rail 6, driving... Move the mounting plate 9 and the drone on it to the required horizontal position, then start the motor 14. The motor drives the connecting shaft 8 to rotate through the spur gear set 15, thereby adjusting the angle of the mounting plate 9 and the drone to adapt to different directional requirements. The mounting plate 9 is made of aluminum alloy, which is lightweight and high-strength, making it suitable for drone mounting. The mounting shell 13 is made of ABS engineering plastic, which has good impact resistance and is suitable for long-term use in complex outdoor environments. After completing all the above settings, a comprehensive functional test should be performed to confirm that all components are operating normally. In daily use, the connection points should be checked regularly to ensure they are secure. Dust should be cleaned from the surfaces of moving parts such as the electric slide rail 6 and the electric slider 7 to ensure smooth operation. Observe the parts for signs of wear and replace them in time if necessary to ensure long-term stable operation of the equipment. To use the equipment again, repeat the above steps.
