Description

Technical Field

[0001] This utility model relates to the technical field of unmanned aerial vehicles (UAVs), and specifically to a UAV flight collision avoidance device. Background Technology

[0002] A drone is an aircraft that does not require a person to ride on it and can achieve flight control by its own power or remote control device. It combines cutting-edge achievements in aviation technology, electronic information technology, automatic control technology and sensor technology. Through data interaction between the onboard computer system and the ground control station, it can complete complex flight missions according to preset programs or real-time commands.

[0003] A drone flight collision avoidance device, disclosed on the Chinese patent website (publication number CN216734792U), includes a drone body, a buffer cylinder body, and a support plate. The buffer cylinder body contains a repulsive magnet slidably connected to its interior. One end of the repulsive magnet is fixedly connected to a collision avoidance rod that penetrates the buffer cylinder body and is slidably connected to the penetration portion. A mounting block is fixedly connected to the upper end of the collision avoidance rod, and a rubber collision avoidance plate is fixedly connected to the upper end of the mounting block. A pressure-sensing pad is fixedly connected inside the rubber collision avoidance plate. An electromagnet, cooperating with the pressure-sensing pad and the repulsive magnet, is fixedly connected to the other end of the repulsive magnet inside the buffer cylinder body. This drone flight collision avoidance device can effectively protect the drone from collisions during flight, preventing damage to the rotor blades and thus avoiding drone crashes and property damage.

[0004] The solution also has the following problems: the upper end of the mounting block is fixedly connected to a rubber anti-collision plate. If the anti-collision plate is damaged when the drone collides, it is not easy to quickly disassemble and replace it, which affects the subsequent flight use of the drone and has low practicality. Therefore, it has certain drawbacks. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a drone flight collision avoidance device.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drone flight anti-collision device includes a drone body, wings are installed at the four corners of the drone body, a base is installed at the bottom of the wings, and grooves are symmetrically opened on both sides of one side of the outer end of the base. A buffer component is arranged inside the groove. A first damper is installed on the outside of the base and between the two grooves. A bearing seat is installed at one end of the first damper. A cavity is opened inside the bearing seat. A quick-release component is arranged inside the cavity. A bearing plate is installed on the outside of the bearing seat. An anti-collision frame is installed on one side of the outer side of the bearing plate.

[0007] The beneficial effects of this utility model are as follows: When a collision occurs during the flight of a drone, the anti-collision frame is first subjected to the impact force. At the same time, the first damper absorbs part of the impact energy through its own damping characteristics, playing a preliminary buffering role. When the collision occurs, the bearing seat is displaced under the impact force, and the angle of the adjusting rod changes accordingly, thereby pushing the slider to move in the groove and the slider to squeeze the second damper. The second damper further absorbs the impact energy. Through the double buffer structure, the damage to the drone body caused by the collision is effectively reduced. The limiting block on the bearing plate is aligned with the limiting groove on the bearing seat and inserted. After the limiting block is fully inserted into the limiting groove, the limiting rod is inserted into the limiting block under the action of the squeezing wedge through the quick release component, thereby locking the limiting block and fixing the bearing plate on the bearing seat. It is convenient to disassemble and install, and it is easy to disassemble and replace the anti-collision frame when it is damaged.

[0008] Furthermore, the buffer assembly includes a second damper installed on the inner side wall of the slide groove. A slider is installed at one end of the second damper and inside the slide groove. An adjusting rod is hinged to the outside of the slider via a pin. The end of the adjusting rod away from the slider is hinged to the outside of the support seat via a pin. The second damper further absorbs the impact energy, effectively reducing the damage to the UAV body from the collision.

[0009] Furthermore, the quick-release assembly includes a threaded rod installed between the top and bottom of the inner side of the cavity. The top pivot of the threaded rod extends through the top of the support seat and is fitted with a knob. A trapezoidal block is installed on the outer ring surface of the threaded rod. The outer ring surface of the threaded rod is threadedly connected to the inside of the trapezoidal block. The outside of the trapezoidal block fits against the inner wall of the cavity. When the threaded rod rotates, the trapezoidal block moves up and down along the threaded rod.

[0010] Furthermore, symmetrical limit grooves are formed at both ends of the outer side of the bearing seat. Squeezing blocks are symmetrically installed inside the cavity and on both sides of the trapezoidal block. A return spring is installed outside the squeezing blocks, with one end connected to the inner wall of the cavity. A limit rod is installed outside the trapezoidal block and inside the return spring. The end of the limit rod away from the squeezing blocks extends into the limit groove. When the squeezing blocks are squeezed, they move towards the inner wall of the cavity while compressing the return spring. The limit rod follows the squeezing blocks into the limit groove.

[0011] Furthermore, limit blocks are installed at both ends of the outer side of the bearing plate. The outer ring size of the limit block is adapted to the inner side wall size of the limit groove. When the limit block is inserted into the inside of the limit groove, one end of the limit rod can be inserted into the inside of the limit block. The limit rod is inserted into the inside of the limit block by the quick release assembly under the action of the squeezing wedge, thereby locking the limit block.

[0012] Furthermore, positioning holes are provided at the four corners of the outer side of the support base, and positioning rods are installed at the four corners of the outer side of the support plate. The outer ring size of the positioning rod is adapted to the inner wall size of the positioning hole. The cooperation between the positioning rod and the positioning hole plays a positioning and guiding role, ensuring that the support plate can be accurately installed on the support base.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0017] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0018] Example 1 Figure 1 This is a schematic diagram of the overall structure of a drone flight collision avoidance device provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the supporting structure of this utility model. Figure 1 , Figure 2 As shown, the device includes a drone body 1. Wings 2 are installed at the four corners of the drone body 1. A base 3 is installed at the bottom of the wing 2. Slide grooves 301 are symmetrically opened on both sides of one end of the base 3. A buffer component 4 is installed inside the slide groove 301. A first damper 5 is installed on the outside of the base 3 and between the two slide grooves 301. A bearing seat 6 is installed at one end of the first damper 5. A cavity 601 is opened inside the bearing seat 6. A quick-release component 7 is installed inside the cavity 601. A bearing plate 8 is installed on the outside of the bearing seat 6. A collision protection frame 9 is installed on one side of the outside of the bearing plate 8.

[0019] When a collision occurs during the flight of the drone, the anti-collision frame 9 is the first to be impacted. The impact force is transmitted to the bearing seat 6 through the bearing plate 8. The bearing seat 6 compresses the first damper 5. The first damper 5 absorbs part of the impact energy through its own damping characteristics, playing a preliminary buffering role.

[0020] Figure 3 This is a schematic diagram of the layered structure of the bearing seat part of this utility model. Figure 4 This is a schematic diagram of a portion of the buffer component of this utility model. (See diagram below.) Figure 3 , Figure 4 As shown, the buffer assembly 4 includes a second damper 10 installed on the inner side wall of the slide 301. A slider 11 is installed at one end of the second damper 10 and inside the slide 301. An adjusting rod 12 is hinged to the outside of the slider 11 by a pin. The end of the adjusting rod 12 away from the slider 11 is hinged to the outside of the bearing seat 6 by a pin.

[0021] When a collision occurs, the bearing seat 6 is displaced under the impact force, and the angle of the adjusting rod 12 changes accordingly, thereby pushing the slider 11 to move within the slide groove 301. The slider 11 squeezes the second damper 10, and the second damper 10 further absorbs the impact energy. Through the double buffer structure, the damage to the UAV body 1 caused by the collision is effectively reduced.

[0022] The quick-release assembly 7 includes a threaded rod 13 installed between the top and bottom of the inner side of the cavity 601. The top pivot of the threaded rod 13 passes through the top of the bearing seat 6 and a knob 14 is installed thereon. A trapezoidal block 15 is installed on the outer ring surface of the threaded rod 13. The outer ring surface of the threaded rod 13 is threadedly connected to the inside of the trapezoidal block 15. The outside of the trapezoidal block 15 fits against the inner wall of the cavity 601.

[0023] When the anti-collision frame 9 is damaged and needs to be disassembled and replaced, turn the knob 14. The knob 14 drives the threaded rod 13 to rotate. Since the trapezoidal block 15 is threadedly connected to the threaded rod 13 and its exterior is in contact with the inner wall of the cavity 601, the trapezoidal block 15 will move up and down along the threaded rod 13 under the action of the thread.

[0024] Figure 5 This is a schematic diagram of the quick-release component of this utility model. (See attached diagram.) Figure 5 As shown, limit grooves 602 are symmetrically opened at both ends of the outer side of the bearing seat 6. Inside the cavity 601 and on both sides of the trapezoidal block 15, compression blocks 16 are symmetrically installed. A return spring 17 is installed on the outside of the compression blocks 16. One end of the return spring 17 is connected to the inner side wall of the cavity 601. A limit rod 18 is installed on the outside of the trapezoidal block 15 and inside the return spring 17. The end of the limit rod 18 away from the compression blocks 16 extends into the interior of the limit groove 602.

[0025] During the operation of the quick-release assembly 7, when the trapezoidal block 15 moves up and down, its inclined surface contacts the inclined surface of the pressing inclined block 16 and relative sliding occurs. After being pressed, the pressing inclined block 16 moves towards the inner wall of the cavity 601 and compresses the reset spring 17. The limiting rod 18 follows the pressing inclined block 16 to move into the limiting groove 602.

[0026] Limiting blocks 19 are installed at both ends of the outer side of the bearing plate 8. The outer ring size of the limiting block 19 is adapted to the inner side wall size of the limiting groove 602. When the limiting block 19 is connected to the inside of the limiting groove 602, one end of the limiting rod 18 can be connected to the inside of the limiting block 19.

[0027] When installing the anti-collision frame 9, the limiting block 19 on the bearing plate 8 is aligned with the limiting groove 602 on the bearing seat 6 and inserted. After the limiting block 19 is fully inserted into the limiting groove 602, the limiting rod 18 is inserted into the limiting block 19 by the quick release assembly 7 under the action of the pressing inclined block 16, thereby locking the limiting block 19 and fixing the bearing plate 8 on the bearing seat 6.

[0028] Example 2 Based on the above embodiments, this embodiment also makes the following improvements, such as... Figure 3 , Figure 4 As shown, Positioning holes 603 are provided at the four corners of the outer side of the bearing seat 6, and positioning rods 20 are installed at the four corners of the outer side of the bearing plate 8. The outer ring size of the positioning rod 20 is matched with the inner side wall size of the positioning hole 603.

[0029] When installing the anti-collision bracket 9, the positioning rod 20 on the bearing plate 8 is aligned with the positioning hole 603 on the bearing seat 6 and inserted. The cooperation between the positioning rod 20 and the positioning hole 603 plays a positioning and guiding role, ensuring that the bearing plate 8 can be accurately installed on the bearing seat 6, so that the limiting block 19 can be smoothly inserted into the limiting groove 602, thereby improving the installation efficiency and accuracy.

[0030] The implementation principle of the anti-collision device for drones in this embodiment is as follows: When the device is used, when a collision occurs during the flight of the drone, the anti-collision frame 9 is first subjected to the impact force. The impact force is transmitted to the support seat 6 through the support plate 8. The support seat 6 compresses the first damper 5. The first damper 5 absorbs part of the impact energy through its own damping characteristics, playing a preliminary buffering role. When the collision occurs, the support seat 6 is displaced under the action of the impact force, and the angle of the adjusting rod 12 changes accordingly, thereby pushing the slider 11 to move in the slide groove 301. The slider 11 compresses the second damper 10, and the second damper 10 further absorbs the impact energy. The double buffer structure effectively reduces the damage to the drone body 1 caused by the collision. When the anti-collision frame 9 is damaged and needs to be disassembled and replaced, the knob 14 is turned. The knob 14 drives the threaded rod 13 to rotate. Since the trapezoidal block 15 is threadedly connected to the threaded rod 13 and its exterior is attached to the inner side wall of the cavity 601, the trapezoidal block 15 will move up and down along the threaded rod 13 under the action of the thread. When block 15 moves up and down, its inclined surface contacts the inclined surface of the extrusion block 16 and relative sliding occurs. After being extruded, the extrusion block 16 moves towards the inner wall of the cavity 601 and compresses the return spring 17. The limiting rod 18 moves with the extrusion block 16 into the limiting groove 602. When installing the anti-collision frame 9, the limiting block 19 on the bearing plate 8 is aligned with the limiting groove 602 on the bearing seat 6 and inserted. After the limiting block 19 is fully inserted into the limiting groove 602, the limiting rod 18 is moved into the extrusion block 16 by the quick-release assembly 7. Driven by 6, the limit block 19 is inserted into the spacer block 19, thereby locking the limit block 19 and fixing the bearing plate 8 on the bearing seat 6. When installing the anti-collision frame 9, the positioning rod 20 on the bearing plate 8 is aligned with the positioning hole 603 on the bearing seat 6 and inserted. The cooperation between the positioning rod 20 and the positioning hole 603 plays a positioning and guiding role, ensuring that the bearing plate 8 can be accurately installed on the bearing seat 6, and that the limit block 19 can be smoothly inserted into the limit groove 602, improving installation efficiency and accuracy, making operation convenient and more practical.
