Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) anti-collision protection, in particular to a detachable UAV anti-collision protection device. Background Art

[0002] Unmanned aerial vehicles (UAVs) have been widely used in various fields due to their flexibility, cost-effectiveness, and ease of use. Whether as an ideal choice for photography enthusiasts and tourists, capturing unique perspectives and scenery from hard-to-reach places, or in areas such as agricultural monitoring, environmental monitoring and protection, disaster assessment and rescue, and infrastructure inspection, UAVs have demonstrated their enormous potential and value.

[0003] However, existing drone designs have some significant flaws, particularly in terms of collision avoidance. First, the rotor, one of the key components of a drone, is responsible for providing lift and flight power, and is crucial to the drone's control stability and flight efficiency. However, in complex and changing flight environments, such as densely wooded forests, between urban buildings, or in areas with dense power lines, the rotor is extremely susceptible to encountering various potential obstacles. Once a collision occurs, it will not only interrupt the flight mission, but may also cause rotor damage, motor failure, and even more serious flight accidents. Unfortunately, there is currently a lack of effective collision protection devices for rotors on the market.

[0004] Secondly, traditional collision avoidance devices typically feature an integrated design that cannot be easily removed or adjusted. This design limits the user's ability to flexibly configure collision avoidance to suit specific flight environments and mission requirements. For example, flying over open fields may require less collision avoidance, while navigating between urban buildings may require more comprehensive protection. However, the integrated design of the collision avoidance device prevents users from flexibly adjusting it to their specific needs, thus impacting the drone's suitability and efficiency.

[0005] Furthermore, existing collision protection devices often lack adequate structural cushioning. When a drone collides directly with an obstacle, these devices often fail to effectively absorb the impact energy, transferring the force directly to the drone, causing severe mechanical damage. This lack of cushioning not only reduces the drone's durability but also increases maintenance costs and operational risks. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is that the integrated setting of the anti-collision protection device cannot be flexibly adjusted by the user according to actual conditions, thereby affecting the applicability and efficiency of the drone.

[0036] Reference Figure 1-Figure 3 This embodiment provides a detachable UAV anti-collision protection device, which includes, through scientific and reasonable structural design, achieving efficient anti-collision performance when the UAV is operating in a complex environment, and at the same time having good detachability and modularity, suitable for various types of UAV platforms, and has broad application prospects and practical value.

[0037] Main component 1;

[0038] An anti-collision protection component 2, used to absorb and mitigate collision energy acting on the main element 1 in the horizontal direction; and

[0039] The anti-collision protection assembly 2 is connected to the main body element 1 in a quick and detachable manner via the mounting element 3 .

[0040] Reference Figure 2-Figure 6 As an optional embodiment, the main component 1 includes a drone body 11, a bracket 12 is installed on the side wall of the drone body 11, and the drone body 11 is connected to a brushless motor 14 through a fixing seat 13 on the bracket 12, wherein the brushless motor 14 drives the rotor 15 to rotate, and a fixed protective frame 16 is installed on the side wall of the drone body 11.

[0041] The anti-collision protection assembly 2 includes a detachable assembly 21 arranged at the top of the drone body 11 , a buffer 22 is installed at the end of the detachable assembly 21 , and an anti-collision member 23 is installed on the side wall of the buffer 22 .

[0042] Reference Figure 4-Figure 7 In one embodiment provided in the present application, the disassembly and assembly part 21 includes a disassembly and assembly seat 211 arranged at the end of the drone body 11, a clamping block 212 is installed on the side wall of the disassembly and assembly seat 211, a first spring 213 is fixedly connected to the lower surface of the disassembly and assembly seat 211, and one end of the first spring 213 is fixedly connected to a fastening plate 214.

[0043] The buffer member 22 includes a fixed block 221 arranged at the top of the disassembly seat 211. The outer walls of both sides of the fixed block 221 are connected to the first connecting rod 222. One end of the first connecting rod 222 is sleeved with the third connecting rod 223. One end of the third connecting rod 223 is sleeved with the fixing rod 224.

[0044] The first connecting rod 222 is sleeved with a second spring 225 , one end of the second spring 225 is tightly attached to the third connecting rod 223 , and the fixing rod 224 is sleeved with a third spring 226 .

[0045] A fourth connecting rod 227 is mounted on the side wall of the fixed block 221 , wherein the fourth connecting rod 227 is movably mounted inside the fifth connecting rod 228 , and a fourth spring 229 is sleeved on the side wall of the fourth connecting rod 227 .

[0046] The anti-collision member 23 includes a first side anti-collision frame 231 arranged at the end of the fifth link 228, the fifth link 228 is connected to the first side anti-collision frame 231 through a first connecting seat 232, and an elastic member 233 is installed on the side wall of the fifth link 228, and the end of the elastic member 233 away from the fifth link 228 is connected to the second side anti-collision frame 235 through a second connecting seat 234.

[0047] A movable protective frame 236 at the bottom end of the fixed rod 224 forms a circular shape with the fixed protective frame 16 to protect the rotor 15;

[0048] The elastic member 233 includes an elastic link 233a provided on the side wall of the fifth link 228. The side wall of the elastic link 233a is sleeved with a sixth link 233b. A fifth spring 233c is provided between the elastic link 233a and the sixth link 233b.

[0049] Reference Figure 8-Figure 9 In one embodiment provided in the present application, the mounting element 3 includes a landing gear 31 arranged at the bottom end of the fixing seat 13, and a camera 32 and a sensor 33 are fixedly connected to the outer walls on both sides of the drone body 11, respectively. A mounting seat 34 is provided at the top of the drone body 11, and a mounting groove 35 is provided in the middle position of the mounting seat 34. A positioning block 36 is installed inside the mounting groove 35, and a positioning notch 37 is provided at the end of the positioning block 36. A card slot 38 is provided at the bottom end of the positioning block 36.

[0050] It should be noted that the anti-collision protection assembly 2 is quickly and removably connected to the main body 1 via the mounting element 3. During installation, the disassembly seat 211 is aligned with the mounting slot 35 on the mounting seat 34, initially positioned using the positioning notch 37 of the positioning block 36, and then inserted. The disassembly seat 211 is then rotated to engage the locking block 212 with the locking slot 38, completing the locking process. A first spring 213 pushes the fastening plate 214 against the inner wall of the mounting slot 35, enhancing the stability of the connection. Disassembly requires only reverse rotation and removal, making it easy to operate and allowing for flexible configuration based on different flight missions.

[0051] When the drone encounters a horizontal collision, the anti-collision member 23 bears the brunt of the impact. This impact force is transmitted to the buffer member 22 via the fifth connecting rod 228. The buffer member 22 is composed of a fixed block 221, a first connecting rod 222, a third connecting rod 223, a fixed rod 224, a second spring 225, and a third spring 226, forming a multi-stage buffer structure:

[0052] The second spring 225 sleeved on the first connecting rod 222 is used to absorb impacts from different directions;

[0053] The third spring 226 on the fixing rod 224 further alleviates the impact force in the vertical direction;

[0054] At the same time, the fourth connecting rod 227 is movably installed inside the fifth connecting rod 228 and is provided with a fourth spring 229, which can produce elastic deformation when subjected to a lateral impact, thereby effectively dispersing the force and improving the overall impact resistance.

[0055] The anti-collision member 23 includes a first side anti-collision frame 231 and a second side anti-collision frame 235, which are connected to the fifth connecting rod 228 via a first connecting seat 232 and a second connecting seat 234, respectively. The elastic member 233, consisting of an elastic connecting rod 233a, a sixth connecting rod 233b, and a fifth spring 233c, is capable of elastically deforming when subjected to external forces, thereby absorbing impact energy and preventing it from being directly transmitted to the drone body 11. Furthermore, a movable protective frame 236 is connected to the bottom of the fixed rod 224. Together with the fixed protective frame 16 on the side wall of the drone body 11, it forms a circular space, providing surround protection for the rotor 15 and preventing damage from accidental collisions during flight.

[0056] The drone body 11 within the main component 1 is connected to a mounting base 13 via a bracket 12, and a brushless motor 14 drives the rotors 15 to achieve flight. The mounting component 3 also includes landing gear 31, located at the bottom of the mounting base 13, providing stable takeoff and landing support for the drone. Furthermore, cameras 32 and sensors 33 are located on either side of the drone body 11, respectively, for flight status monitoring and environmental awareness, enhancing the overall system's intelligence and safety.

[0057] In some embodiments, as Figure 9-10 This embodiment is different from the above embodiments in that the mounting seat 34 is not limited to a circle, but can also be a triangle or a rectangle.

[0058] The triangle has a natural structural stability and is one of the most stable geometric shapes. This means that when subjected to external forces, the triangular mount can better disperse the force, reduce local stress concentration, and improve the impact resistance of the overall structure.

[0059] For the same coverage area, the triangle can provide sufficient support using less material, which helps to reduce the overall weight of the drone, which is very beneficial for improving flight performance: such as endurance time, speed, etc.

[0060] The unique vertices and corners of the triangle serve as reference points, making it easy to quickly and accurately align and secure the mount, simplifying the installation process.

[0061] Compared to triangles, rectangles provide a larger surface contact area, which increases the friction and stability between the connection points with the drone body. It is particularly suitable for application scenarios that need to withstand larger loads or more frequent collisions.

[0062] Rectangular mounts typically allow more components to be placed on or around them, such as sensors, antennas, and other electronic devices, which helps optimize space utilization and maintain good aerodynamic characteristics.

[0063] In industrial production, rectangle is one of the more common geometric shapes, which is easy to achieve standardized production and modular design, convenient for batch manufacturing and compatibility with other accessories.

[0064] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
