Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV with a modular, quick-assembly and disassembly multispectral camera mount. Background Technology

[0002] Modular design of unmanned aerial vehicles (UAVs) is a software engineering design method that decomposes a large, complex system into a series of small, independent, and reusable modules.

[0003] Chinese utility model patent CN222629573U discloses a modular quick-connect device for unmanned aerial vehicles (UAVs). This device, by creating multiple arm slots, eliminates the need for bolts to secure the arm modules; the top cover is simply threaded onto the circumference of the truncated cone for clamping and fixing. However, this device has certain drawbacks in practical use. For example, the threaded connection is prone to loosening due to vibration during UAV flight, causing the arms to wobble or shift, affecting the UAV's flight stability and controllability. Therefore, this paper proposes a modular quick-connect device for mounting multispectral cameras on UAVs to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, quick-assembly and disassembly multispectral camera mount for drones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular, quick-assembly multispectral camera mount for a drone includes a body with a circular outer wall and slots around its circumference. Each slot contains a connecting block (greyish brown). An arm is fixedly connected to the outer wall of each connecting block, and a load-bearing block is located at the end of the arm. A central shaft is fixedly connected to the axis of the body's end face. An annular locking plate is slidably connected to the outer wall of the central shaft. Each set of connecting blocks has a slot on its end face with an arc-shaped interior. The annular locking plate is engaged in each slot. A connecting cover is threaded to the outer wall of the central shaft end, with its lower end contacting the end face of the annular locking plate. A through slot is formed on the end face of the annular locking plate, and a slider is movably connected within the through slot. A limit groove is formed on the outer wall of the connecting cover, and a limit plate is fixedly connected to the outer wall of the slider. An elastic component is provided within the through slot to drive the limit plate to fit tightly within the limit groove.

[0007] Preferably, the elastic component includes a slide rod fixedly connected in the through groove, a slider slidably connected to the outer wall of the slide rod, and a second spring sleeved on the outer wall of the slide rod, with both ends of the second spring fixedly connected to the inner wall of the through groove and the outer wall of the slider, respectively.

[0008] Preferably, the support block has an installation groove, and the propeller is engaged in the installation groove.

[0009] Preferably, a sliding rod is slidably connected to the outer wall of the bearing block, and the sliding rod is engaged inside the propeller. A limiting block is fixedly connected to the end of the sliding rod away from the propeller, and the radius of the limiting block is larger than the radius of the sliding rod.

[0010] Preferably, a spring is sleeved on the outer wall of the slide rod, and the two ends of the spring are fixedly connected to the bearing block and the limiting block, respectively.

[0011] Preferably, a camera body is provided at the lower end of the body, and two sets of support legs are symmetrically arranged at the lower end of the body.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses components such as an annular retaining plate, connecting block, connecting cover, slider, limiting plate and spring 2. The annular retaining plate engages with the slot on the connecting block, and the spring 2 pushes the limiting plate to fit tightly into the limiting slot of the connecting cover, forming a double stable structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A modular, quick-assembly multispectral camera mount drone includes a body 1. The outer wall of the body 1 is circular, and a slot 2 is formed around the circumference of the outer wall. Each slot 2 contains a connecting block 11 in a brownish-gray color. An arm 4 is fixedly connected to the outer wall of the connecting block 11. A bearing block 13 is provided at the end of the arm 4. A central shaft 7 is fixedly connected to the center of the end face of the body 1. An annular plate 6 is slidably connected to the outer wall of the central shaft 7. Each set of connecting blocks 11 has a fixing groove 12 with an arc-shaped interior. The annular plate 6 is locked in each set of fixing grooves 12. A connecting cover 10 is threadedly connected to the outer wall of the end of the central shaft 7, and its lower end contacts the end face of the annular plate 6. A through groove is formed through the end face of the annular plate 6, and a slider 18 is movably connected in the through groove. A limit groove 20 is formed on the outer wall of the connecting cover 10. A limit plate 9 is fixedly connected to the outer wall of the slider 18. An elastic component is provided in the through groove to drive the limit plate 9 to fit tightly in the limit groove 20.

[0022] Furthermore, this device uses the engagement of the annular locking plate 6 with the fixing groove 12 on the connecting block 11, and the elastic component drives the limiting plate 9 to fit tightly with the limiting groove 20, forming a double stable structure. During the flight of the UAV, even if it encounters strong vibrations, the arm 4 will not shake or shift, effectively ensuring the flight stability and controllability of the UAV.

[0023] The elastic component includes a slide rod 17 fixedly connected in the through groove, a slider 18 slidably connected to the outer wall of the slide rod 17, and a second spring 19 sleeved on the outer wall of the slide rod 17. The two ends of the second spring 19 are fixedly connected to the inner wall of the through groove and the outer wall of the slider 18, respectively.

[0024] Furthermore, the spring 19, through the elastic force generated by its own elastic deformation, pushes the slider 18 to make the limiting plate 9 fit tightly in the limiting groove 20. When the drone vibrates, it continuously provides a stable clamping force to the limiting plate 9, ensuring that the engagement structure between the annular plate 6 and the connecting block 11 is stable and preventing the arm 4 from loosening.

[0025] The bearing block 13 has an installation groove, and the propeller 5 is engaged in the installation groove. The outer wall of the bearing block 13 is slidably connected to the connecting rod 14, and the connecting rod 14 is engaged in the propeller 5. The end of the connecting rod 14 away from the propeller 5 is fixedly connected to the limiting block 15, and the radius of the limiting block 15 is larger than the radius of the connecting rod 14. The outer wall of the connecting rod 14 is fitted with a spring 16, and the two ends of the spring 16 are fixedly connected to the bearing block 13 and the limiting block 15 respectively.

[0026] Furthermore, spring 16 provides elastic force to connecting rod 14, ensuring that connecting rod 14 remains tightly engaged with propeller 5, thus ensuring that connecting rod 14 is continuously and securely engaged with propeller 5 and preventing propeller 5 from loosening or falling off, thereby further improving the stability and safety of the UAV power system.

[0027] The camera body 8 is located at the lower end of the body 1, and two sets of support legs 3 are symmetrically arranged at the lower end of the body 1.

[0028] In this invention, the device is used as follows: During assembly, the connecting block 11 is first inserted into the slot 2 on the outer wall of the body 1 to initially position the arm 4 to the body 1. Then, the annular locking plate 6 slides down the outer wall of the central shaft 7, engaging the arc-shaped fixing groove 12 on the end face of the connecting block 11 to initially fix the arm 4. Next, the connecting cover 10 is threaded onto the outer wall of the end of the central shaft 7. The lower end of the connecting cover 10 contacts and presses down on the end face of the annular locking plate 6. Simultaneously, the spring 19 in the through groove pushes the slider 18, causing the limiting plate 9 to tightly fit into the limiting groove 20 on the outer wall of the connecting cover 10, forming a double-stabilized structure. This completes the secure connection between the arm 4 and the body 1. Compared to traditional threaded connections, this structural design effectively resists vibrations during drone flight and prevents the arm 4 from loosening or shifting.

[0029] During propeller 5 installation, the propeller 5 is initially positioned by engaging it in the mounting slot within the support block 13. At this time, the connecting rod 14 automatically engages with the inside of the propeller 5 under the elastic force of the spring 16. The limiting block 15 prevents the connecting rod 14 from detaching from the propeller 5, ensuring that the propeller 5 is securely installed at the end of the arm 4. During drone flight, the spring 16 continuously provides elastic force to the connecting rod 14, ensuring a tight engagement between it and the propeller 5. Even under vibrations such as airflow impacts, the propeller 5 will not loosen or fall off, ensuring the stable operation of the drone's power system.

[0030] When the drone is in operation, the propellers 5 on the arms 4 rotate to provide flight power, and the camera body 8 located at the lower end of the fuselage 1 performs multispectral imaging. During the take-off and landing phases, the two sets of outriggers 3 symmetrically located at the lower end of the fuselage 1 play a role, effectively buffering the impact force of the ground through their own structural deformation, protecting the camera body 8 and the internal electronic components of the drone from damage.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
