Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV flight anti-collision buffer device. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Compared to manned aircraft, UAVs are often better suited for tasks that are too "dull, dirty, or dangerous." UAVs can be categorized into military and civilian applications. In the military field, UAVs are divided into reconnaissance aircraft and target drones; in the civilian field, UAVs are used in various industry applications.

[0003] Currently, with the widespread use of drones, their scale is constantly increasing. However, when drones operate in complex environments, they may collide with external objects, causing the drone propellers to bear a large impact force, which in turn damages the propeller blades and affects the service life of the drone. Utility Model Content

[0004] The purpose of this invention is to provide a drone flight anti-collision buffer device to solve the problem that when a drone collides with an external object, the drone propeller bears a large impact force, which in turn shortens the drone's service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone flight anti-collision buffer device, comprising a drone body, and further comprising:

[0006] A base plate is located at the bottom, a rotor is located at the top, and a base rod is located at the bottom of the rotor. The bottom of the rotor is rotatably connected to the inside of the base rod, and the bottom of the base rod is fixedly connected to the top of the base plate.

[0007] A buffer assembly is disposed on the outside of the rotor. The buffer assembly includes a connecting ring disposed on the outside of the rotor. The inner ring of the connecting ring is provided with an inner ring. A connecting groove is opened inside the connecting ring. A magnetic ring is slidably connected to the outside of the base rod.

[0008] Preferably, the inner wall of the connecting ring is provided with an energy-absorbing ring, and a connecting rod is fixedly connected to the bottom of the connecting ring, with the bottom of the connecting rod being fixedly connected to the top of the magnetic ring.

[0009] Preferably, the magnetic ring has an internal mounting groove, and the base rod is fixedly connected to an mounting strip on its outer side.

[0010] Preferably, a buffer ring is provided inside the connecting groove, and a fixing pipe is fixedly connected to the inner wall of the connecting ring.

[0011] Preferably, a first damping seat is provided inside the fixing tube, and a first spring is welded to the end of the first damping seat away from the fixing tube, and a slot is provided inside the fixing tube.

[0012] Preferably, a movable rod is welded to the end of the first spring away from the first damping seat, and a locking block is fixedly connected to the outside of the movable rod.

[0013] Preferably, a top pipe is fixedly connected to the bottom of the base plate, a second damping seat is provided at the top of the inner cavity of the top pipe, a second spring is welded to the bottom of the second damping seat, a support frame is welded to the bottom of the second spring, and an elastic pad is provided at the bottom of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, by incorporating a buffer assembly, disperses and absorbs the impact force on the rotor under the action of the buffer ring, thereby weakening the impact force on the rotor. The impact force, after being weakened by the buffer ring, is transmitted to the energy-absorbing ring, which further weakens the remaining impact force. The further weakened impact force is then transmitted to the moving rod, causing a certain degree of deformation in the moving rod. The impact force is then transmitted through the first spring to the interior of the first damping seat. Under the action of the first damping seat, the impact force on the rotor is further reduced. Simultaneously, the inner ring is made of carbon fiber composite material, further reducing the impact force on the rotor and providing comprehensive protection for the rotor. Furthermore, workers can assemble and disassemble the two connecting rings using a magnetic ring, and the connecting rod has a certain degree of elasticity, facilitating the installation and disassembly of the inner ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a drone flight collision avoidance buffer device includes a drone body 1. By setting the drone body 1, the various components of the device are positioned and installed. It also includes:

[0023] The base plate 2 at the bottom supports the rotor 3, enabling it to function normally. The rotor 3 at the top allows the drone body 1 to take off and land normally. The base rod 4 at the bottom of the rotor 3 facilitates the assembly and disassembly of the buffer assembly 5 and reduces the impact force on the rotor 3. The bottom of the rotor 3 is rotatably connected to the inside of the base rod 4, and the bottom of the base rod 4 is fixedly connected to the top of the base plate 2.

[0024] The buffer assembly 5, located on the outside of the rotor 3, weakens the impact force on the rotor 3 in the event of a collision, thereby stabilizing the rotor 3 and reducing the probability of damage. The buffer assembly 5 includes a connecting ring 51 located on the outside of the rotor 3. The connecting ring 51 allows for the installation of the buffer ring 10 and the positioning and placement of various components of the buffer assembly 5. The inner ring 52 of the connecting ring 51 weakens the impact force on the rotor 3 in the event of a collision, thus ensuring the rotor 3 remains intact. The connecting ring 51 has a connecting groove 53 inside, which facilitates the positioning and installation of the buffer ring 10. A magnetic ring 54 is slidably connected to the outside of the base rod 4, allowing for easy assembly and disassembly of the buffer assembly 5. The assembly 5 is also connected to the outside of the base rod 4 via the magnetic ring 54.

[0025] refer to Figure 2 and Figure 3 As shown, an energy-absorbing ring 6 is provided on the inner wall of the connecting ring 51. The energy-absorbing ring 6 is made of silicone rubber as the base and 40% carbonyl iron powder as the additive. A connecting rod 7 is fixedly connected to the bottom of the connecting ring 51. By setting the connecting rod 7, the connecting ring 51 and the magnetic ring 54 can be stably connected. At the same time, the connecting rod 7 has a certain degree of elasticity, which makes it easy for the staff to disassemble and assemble the magnetic ring 54. The bottom of the connecting rod 7 is fixedly connected to the top of the magnetic ring 54.

[0026] The magnetic ring 54 has an internal mounting groove 8. The mounting groove 8 allows the operator to position the mounting groove 8 using the mounting strip 9. The mounting strip 9 is fixedly connected to the outside of the bottom rod 4. Both the bottom rod 4 and the mounting strip 9 can be attracted to the magnetic ring 54, making it easy for the operator to assemble and disassemble the magnetic ring 54.

[0027] A buffer ring 10 is provided inside the connecting groove 53. The buffer ring 10 is made of liquid silicone rubber honeycomb frame and its internal filling is shear thickening fluid. A fixed tube 11 is fixedly connected to the inner wall of the connecting ring 51. By setting the fixed tube 11, the first damping seat 12 and the first spring 13 can move normally inside the fixed tube 11.

[0028] The fixed tube 11 is provided with a first damping seat 12. By providing the first damping seat 12, the impact force transmitted through the first spring 13 can be weakened under the action of the first damping seat 12. The first spring 13 is welded to the end of the first damping seat 12 away from the fixed tube 11. The fixed tube 11 is provided with a slot 16. By providing the slot 16, the movement of the moving rod 14 can be kept stable.

[0029] refer to Figure 1 and Figure 4 As shown, a moving rod 14 is welded to one end of the first spring 13 away from the first damping seat 12. A locking block 15 is fixedly connected to the outside of the moving rod 14. By setting the locking block 15, the outside of the locking block 15 is slidably connected to the inner wall of the locking groove 16, thereby making the movement of the moving rod 14 stable.

[0030] The bottom of the base plate 2 is fixedly connected to the top tube 21. The top of the inner cavity of the top tube 21 is provided with a second damping seat 20. By providing the second damping seat 20, the impact force borne by the support frame 17 during the landing of the device can be weakened, thereby making the device stable during landing. A second spring 19 is welded to the bottom of the second damping seat 20. The support frame 17 is welded to the bottom of the second spring 19. An elastic pad 18 is provided at the bottom of the support frame 17.

[0031] Working principle: When the operator uses this device to protect the drone body 1, they first position the magnetic ring 54 using the base rod 4 and mounting strip 9. After one magnetic ring 54 is installed in the designated position, the inner ring 52 and moving rod 14 are positioned and installed. After installation, the other magnetic ring 54 is installed. Then, the buffer ring 10 is inserted into the designated position inside the connecting groove 53. In the event of a collision, the rotor 3 bears a large impact force. Under the action of the buffer ring 10, the transmitted impact force can be weakened, and then the weakened impact force is transmitted through... The connecting ring 51 transmits the impact force to the energy-absorbing ring 6. Under the action of the energy-absorbing ring 6, the transmitted impact force is weakened again. The weakened impact force is transmitted to the moving rod 14 through the energy-absorbing ring 6, which causes the moving rod 14 to slide inside the fixed tube 11. At the same time, the first spring 13 is compressed, so that the impact force can be transmitted to the first damping seat 12 through the first spring 13. Under the action of the first damping seat 12, the transmitted impact force is weakened, which further reduces the impact force on the inner ring 52 and the rotor 3, so that the rotor 3 can remain intact when it is hit.
