Description

Technical Field

[0001] This utility model relates to the field of lidar technology, and in particular to a lidar that is convenient to be mounted on unmanned aerial vehicles. Background Technology

[0002] Drones can be quickly deployed to complex terrains such as mountains, forests, and disaster areas, breaking through the limitations of traditional vehicles such as cars and airplanes to achieve efficient data collection. Drones can fly at low altitudes and, combined with the rapid scanning capabilities of lidar, can achieve real-time monitoring of environmental changes such as floods and landslides. LiDAR generates 3D point cloud data with centimeter-level accuracy by emitting laser pulses and measuring reflection time. It is suitable for scenarios such as terrain mapping and building modeling. Compared with manned aircraft or satellite remote sensing, drones equipped with lidar are lower in cost and more flexible in operation, making them suitable for small and medium-sized projects.

[0003] With the rapid development of drone technology, drones equipped with LiDAR have become one of the key technologies for applications in many fields. This combination device, with its flexibility, efficiency and high precision, has shown an irreplaceable position in surveying, agriculture, forestry, environmental monitoring, disaster emergency response, urban planning and autonomous driving. In scenarios that require rapid response, such as disaster emergency environmental monitoring, the complex installation and disassembly of LiDAR can prolong the deployment time of the equipment and miss the best time for data collection. At the same time, it is necessary to carry a lot of tools to disassemble the LiDAR, which is not only time-consuming, but may also damage the equipment due to improper operation. When the scanning angle of the LiDAR is fixed, it may not be able to cover all the features of the target area. For example, in the surveying of complex terrain, if the LiDAR cannot tilt downwards, it may lead to the loss of data in steep slopes or depressions, affecting the integrity of 3D modeling.

[0027] Example 1:

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a lidar that is convenient to be mounted on a drone. It includes a drone body 1, a mounting frame 2 installed on the bottom of the drone body 1, a first fixed frame 3 and a second fixed frame 4 rotatably connected to the inner wall of the mounting frame 2, a mounting component 5 provided on the outer side of the first fixed frame 3, a connecting frame 6 fixedly connected to the bottom of the mounting frame 2, and an adjustment component 7 provided on the outer side of the connecting frame 6.

[0029] Mounting bracket 2 assists in the rotation of the first fixing bracket 3 and the second fixing bracket 4, thereby facilitating the installation of the radar body 8 on the outside of the UAV body 1. The first fixing bracket 3 and the second fixing bracket 4 can be connected by mounting component 5, which facilitates the installation of the radar body 8. Mounting component 5 can connect the first fixing bracket 3 and the second fixing bracket 4. Connecting bracket 6 can install adjustment component 7.

[0031] Mounting block 51 provides a fulcrum for the installation of limit frame 52. Limit frame 52 supports limit bracket 53 and also limits limit bracket 53 to prevent it from tilting. The cooperation between limit bracket 53 and limit post 54 facilitates the connection between first fixed bracket 3 and second fixed bracket 4, thereby facilitating the installation and disassembly of radar body 8.

[0032] The adjustment assembly 7 includes a drive member 71 disposed on the outside of the connecting frame 6. A mounting rod 72 is rotatably connected to the outside of the connecting frame 6. A mounting column 74 is rotatably connected to the inner wall of the connecting frame 6. A second bevel gear set 73 is disposed on the outside of the mounting column 74, and the second bevel gear set 73 is disposed on the outside of the mounting rod 72.

[0033] The driving component 71 can drive the mounting rod 72 to rotate, the mounting rod 72 drives the second bevel gear set 73 to rotate, and the second bevel gear set 73 drives the mounting column 74 to rotate, thereby facilitating the adjustment of the angle of the radar body 8.

[0034] Example 2:

[0035] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a radar body 8 is installed on the outer side of the mounting column 74, a support frame 9 is fixedly connected to the inner wall of the mounting column 74, a limit strip 10 is rotatably connected to the inner wall of the support frame 9, and a first bolt 11 is threadedly connected to the inner wall of the limit strip 10.

[0037] The cooperation between the support frame 9 and the limiting strip 10 facilitates the fixing of the radar body 8. The first bolt 11 can limit the support frame 9 and the limiting strip 10, thereby facilitating the fixing of the radar body 8 and making it easier to install and disassemble the radar body 8.

[0038] Specifically, a mounting ring 12 is fixedly connected to the outer side of the connecting frame 6, and a limiting ring 13 for limiting the drive component 71 is fixedly connected to the outer side of the mounting ring 12.

[0039] The use of mounting ring 12 and limit ring 13 together can facilitate the fixing of motor 711, thereby improving the stability of motor 711 during operation.

[0040] Specifically, mounting plates 14 are fixedly connected to the outer sides of both the first fixing frame 3 and the second fixing frame 4. The inner wall of the mounting plate 14 is threaded with a second bolt 15, and the outer side of the second bolt 15 is threaded with the inner wall of the mounting frame 2.

[0041] Mounting plate 14 facilitates the rotation of second bolt 15, which limits the first fixing frame 3 and mounting frame 2, thereby facilitating the installation of radar body 8.

[0042] Specifically, a limiting block 16 for limiting the mounting rod 72 is fixedly connected to the outer side of the connecting frame 6, and a limiting piece 17 for preventing the mounting rod 72 from sliding is fixedly connected to the outer side of the mounting rod 72, and the outer side of the limiting block 16 is rotatably connected to one side of the limiting piece 17.

[0043] The limiting block 16 can limit the lateral travel of the mounting rod 72 to prevent the mounting rod 72 from tilting, and the limiting piece 17 can limit the vertical travel of the mounting rod 72 to prevent the mounting rod 72 from sliding.

[0044] Example 3:

[0045] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, a spring 18 is fixedly connected to the outer side of the mounting block 51, and a pull rod 19 is fixedly connected to the outer side of the limiting frame 53, with one end of the spring 18 fixedly connected to the outer side of the limiting frame 53.

[0047] Spring 18 can limit the position of the limiting frame 53, thereby facilitating the connection between the first fixed frame 3 and the second fixed frame 4. Pull rod 19 can pull the limiting frame 53, thereby facilitating the separation of the limiting frame 53 from the limiting post 54, thus facilitating the separation of the first fixed frame 3 and the second fixed frame 4.

[0048] Specifically, the driving component 71 includes a motor 711 mounted on the inner wall of the mounting ring 12, and the output end of the motor 711 is provided with a first bevel gear set 712, which is located on the outside of the mounting rod 72.

[0049] The motor 711 can drive the first bevel gear set 712 to rotate, the first bevel gear set 712 drives the mounting rod 72 to rotate, thereby driving the second bevel gear set 73 and the mounting column 74 to rotate, which facilitates the adjustment of the angle of the radar body 8.

[0050] During use, firstly, during installation, place the mounting bracket 2 against the bottom of the UAV body 1, then rotate the first fixing bracket 3 and the second fixing bracket 4 until they are vertical. Note that at this time, the pull rod 19 should be pulled, and then the second bolt 15 should be rotated to limit the first fixing bracket 3 and the second fixing bracket 4 to the mounting bracket 2, thereby improving the stability during fixing. After the first fixing bracket 3 and the second fixing bracket 4 are limited, the pull rod 19 can be released. At this time, the spring 18 drives the limiting bracket 53 to move horizontally until it is inserted into the limiting post 54, thereby limiting the first fixing bracket 3 and the second fixing bracket 4, and thus limiting the radar body 8. When it is necessary to adjust the angle of the radar body 8, the motor 711 can be started. The motor 711 drives the first bevel gear set 712 to rotate, the first bevel gear set 712 drives the mounting rod 72 to rotate, and the mounting rod 72 drives the second bevel gear set 73 and the mounting post 74 to rotate, thereby adjusting the angle of the radar body 8. After the adjustment is completed, it can be put into operation.
