Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV lidar mounting device. Background Technology

[0002] Airborne lidar measurement, as an emerging space-based Earth observation technology, has made significant breakthroughs in the real-time acquisition of three-dimensional spatial information. The airborne lidar measurement system integrates three technologies: laser scanner, global positioning system, and inertial navigation system.

[0003] When flying in mountainous areas, lidar can accurately depict the three-dimensional outlines of peaks, valleys, and trees, helping drones avoid obstacles. Therefore, lidar is needed to acquire three-dimensional spatial information. However, the traditional lidar installation process is quite cumbersome, which means that more time is needed to complete the installation and debugging of the lidar. The complex installation steps usually require professional technicians to operate, and in some remote areas or in emergency situations, it may not be possible to find suitable professionals in time, resulting in the equipment not being put into use on time. In addition, lidar lacks a protective structure when in use. When it is hit by birds, animals, or large obstacles, the lidar without a protective structure is easily broken. For example, in an outdoor environment, a bird hitting the lidar at high speed may cause cracks or even breakage of the radar shell, exposing the internal components directly to the external environment and increasing the risk of damage.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a drone lidar mounting device, including a drone body 1, a radar body 2 disposed below the drone body 1, a mounting bracket 3 mounted on one side of the radar body 2 via a pivot, a mounting component 4 for connecting with the drone body 1 disposed on the top of the mounting bracket 3, and a protective component 5 disposed on the outer side of the radar body 2.

[0030] The UAV body 1 serves as the carrier and flight platform of the entire installation device, providing flight power and control functions to drive the radar body 2 for spatial movement and operation. It should be noted that the UAV body 1 is existing technology and will not be elaborated upon further. The radar body 2 is the core detection device, which detects the surrounding environment by emitting and receiving laser beams to obtain information such as the distance and position of objects, providing data support for related applications of the UAV body 1, such as surveying and obstacle avoidance. It should be noted that the radar body 2 has the same structural principle as the lidar in the authorized application, CN202323434770.0, and is existing technology, which will not be elaborated upon further. The mounting bracket 3 is designed to install the radar body 2, providing support and fixation, allowing the radar body 2 to be stably installed below the UAV body 1, and providing a certain installation angle and adjustment base. It should be noted that the shaft between the radar body 2 and the mounting bracket 3 is a damping shaft. A damping shaft is a special mechanical component that can reduce vibration and noise during rotation. It converts vibration energy into heat energy through internal damping materials or friction structures, and is existing technology.

[0031] Mounting assembly 4 includes a connecting post 41 fixed to the top of mounting bracket 3. A fixing post 42 is mounted on one end of the connecting post 41, and one end of the fixing post 42 is fixedly connected to the bottom of the UAV body 1. A fixing ring 43 is fixedly connected to one end of the fixing post 42, and a limit ring 44 is rotatably connected to the inner wall of the fixing ring 43 via a rotating shaft.

[0032] The connecting column 41 is used to connect the mounting bracket 3 and the fixing column 42, serving to transmit force and fix the position, connecting the mounting bracket 3 to the UAV body 1. The fixing column 42 is designed to connect the mounting column 41 and the fixing ring 43, and is an important connecting component in the mounting assembly 4, ensuring that the radar body 2 is reliably connected to the UAV body 1 through the mounting bracket 3. The fixing ring 43 is set to connect with the fixing column 42 and provide an installation position for the limiting ring 44. By cooperating with the limiting ring 44, the fixing ring 44 is fixedly installed to the UAV body 1 using bolts 15. The limiting ring 44 is designed to be rotatably connected to the fixing ring 43 through a rotating shaft and fixed to the fixing ring 43 by bolts 15, serving to limit and fix, ensuring that the connecting column 41 and the fixing column 42 are firmly connected, preventing the radar body 2 from shaking or falling off during use.

[0033] The protective component 5 includes a protective plate 51 disposed on the outside of the radar body 2, and the number of protective plates 51 is set to multiple sets, with a connecting plate 52 fixedly connected to the outside of each set of protective plates 51.

[0034] Since the protective plate 51 is located on the outside of the radar body 2, it provides physical protection for the radar body 2, resisting the impact of birds, animals or obstacles, reducing damage to the radar body 2 from external factors, and protecting the outer shell and internal components of the radar body 2. It is noted that the number of protective plates 51 is set to five. When the five sets of protective plates 51 are retracted, they can cover and wrap the radar body 2, thereby achieving the protective effect of the radar body 2. The connecting plate 52 is designed to be fixedly connected with the protective plate 51, and plays the role of transmitting force and fixing the protective plate 51, connecting the protective plate 51 with other parts of the installation device into a whole, ensuring that the protective component 5 can function stably.

[0035] Example 2:

[0036] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, a support frame 6 is fixedly connected to the bottom of the drone body 1, and a motor 7 is fixedly connected to one side of the support frame 6.

[0038] Since the support frame 6 is fixed to the bottom of the UAV body 1, it can provide an installation position for the motor 7, which can play a supporting and fixing role, ensuring that the relevant components can be stably installed on the UAV body 1. The motor 7 is used to provide a power source to drive the threaded rod 8 to rotate, and through mechanical transmission, it drives the protective component 5 to perform corresponding actions, such as adjusting the position or angle of the protective plate 51, so as to achieve better protection for the radar body 2.

[0039] Specifically, a threaded rod 8 is fixedly connected to the output end of motor 7, and a bearing 9 is rotatably connected to the outer side of the threaded rod 8.

[0040] The threaded rod 8 rotates under the drive of the motor 7, converting the rotational motion of the motor 7 into the linear motion of the moving seat 17, thereby realizing the action of the protective component 5.

[0041] Specifically, a fixed seat 10 is rotatably connected to the outer side of the bearing 9, and the outer side of the fixed seat 10 is fixedly connected to one side of the support frame 6. Multiple sets of first mounting shafts 11 are rotatably connected to the inner wall of the fixed seat 10.

[0042] The fixed seat 10 is used to rotatably connect with the bearing 9 and provide an installation position for the first mounting shaft 11, serving as a support and fixation function. At the same time, the design of the first mounting shaft 11 facilitates connection with the fixed seat 10, and the fixed seat 10 is fixed to the support frame 6, preventing the threaded rod 8 from rotating and causing the outer part of it to rotate, thus ensuring that the movable seat 17 can move horizontally.

[0043] Specifically, a connecting plate 12 is rotatably connected to the outer side of the first mounting shaft 11, and a second mounting shaft 13 is rotatably connected to the inner wall of the connecting plate 12, and the number of second mounting shafts 13 is set to multiple sets.

[0044] Since the connecting plate 12 is connected to the fixed base 10 through the first mounting shaft 11 and to the fixed plate 14 through the second mounting shaft 13, it plays the role of connecting and transmitting force, transmitting the motion generated by the rotation of the threaded rod 8 to the fixed plate 14, thereby driving the protective plate 51 to move. Since the second mounting shaft 13 is installed on the inner wall of the connecting plate 12 and is rotatably connected to the fixed plate 14, the fixed plate 14 can rotate around the second mounting shaft 13, further increasing the flexibility and diversity of the protective assembly 5's movement, and ensuring that the protective plate 51 can be adjusted as needed.

[0045] Specifically, a fixing plate 14 is rotatably connected to the outer side of the second mounting shaft 13, and one side of the fixing plate 14 is fixedly connected to one side of the connecting plate 52. A movable seat 17 is rotatably connected to one side of the fixing plate 14 via a rotating shaft, and the inner wall of the movable seat 17 is threadedly connected to the outer side of the threaded rod 8.

[0046] Since the fixed plate 14 is fixedly connected to the connecting plate 52, it plays the role of fixing and transmitting force. The movable seat 17 is designed to connect with the fixed plate 14. When the movable seat 17 moves, it drives the fixed plate 14 to move.

[0047] Example 3:

[0048] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the inner wall of the limiting ring 44 is threaded with bolts 15 for installing the fixing ring 43, and the inner wall of the fixing ring 43 is provided with two sets of threaded holes 16.

[0050] Bolt 15 is used to connect to the inner wall of the limiting ring 44 by thread and screw into the threaded hole 16 on the inner wall of the fixing ring 43, so as to fix the limiting ring 44 and the fixing ring 43 and ensure that the connection between the mounting component 4 and the UAV body 1 is more secure and reliable.

[0051] When installing the radar body 2, first install the connecting post 41 on one end of the fixed post 42, then align the limiting ring 44 with the fixed ring 43, so that the bolt 15 of the limiting ring 44 matches the threaded hole 16 of the fixed ring 43. Then screw the bolt 15 into the threaded hole 16 and tighten it. Through the threaded engagement of the bolt 15 and the threaded hole 16, the limiting ring 44 and the fixed ring 43 are tightly fixed together, thus firmly installing the connecting post 41 and the fixed post 42 under the UAV body 1. When the radar body 2 may be hit by birds, animals or obstacles, the motor 7 starts, and its output end drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 drives the moving seat 17 to move linearly along the threaded rod 8. The movement of the moving seat 17 drives the fixed plate 14 to move. The fixed plate 14 causes the connecting plate 12 to rotate around the first mounting shaft 11 through the second mounting shaft 13, which in turn drives the connecting plate 52 and the protective plate 51 to move, forming a dynamic protective barrier on the outside of the radar body 2, thereby protecting the radar body 2.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
