Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) wings, in particular to an anti-collision UAV wing. Background Art

[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Traditional drone structures do not have anti-collision functions during use, especially in complex areas such as forests, and are easily damaged by wings colliding with foreign objects.

[0003] However, some existing anti-collision structures are too rigid and have poor anti-collision effects. For example, publication number (CN215323311U) describes a curved anti-collision drone wing, which includes a top bar, a crash-resistant anti-collision bar fixedly connected to one side of the top bar, a mounting block fixedly connected to one side of the anti-collision bar, a fixing bar fixedly connected to the upper surface of the top bar, a fixing tube fixedly connected to one side of the fixing bar, a motor mounting tube fixedly connected to one side of the fixing bar, a small gear rotatably connected to the lower surface of the top bar, and a rotatable rotating tube plugged into the upper surface of the small gear. This anti-collision structure is rigid, but suffers from insufficient absorption capacity when impacted, and stress concentration can easily lead to brittle damage. Therefore, we propose an anti-collision drone wing. Summary of the Invention

[0004] The object of the present invention is to provide an anti-collision UAV wing to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an anti-collision UAV wing, comprising a top beam and an anti-collision beam; the top beam is symmetrically distributed along the central axis, an arc-shaped anti-collision beam is provided at the outer end of the top beam, and an extension beam is provided on the inner side of the bottom end of the anti-collision beam; The surface of the anti-collision beam is provided with an anti-collision panel, and the inner side of the anti-collision panel is provided with a pad, the anti-collision panel is a hard rubber panel, and the pad is a flexible rubber panel; The inner cavity of the anti-collision beam is distributed with multiple shock-absorbing springs, and an energy absorption box is arranged between the shock-absorbing spring and the pad; the energy absorption box is a hollow rubber block, and a layered airbag is installed in the inner cavity of the energy absorption box, and an air valve is installed on the inner side of the layered airbag; a miniature two-way air pump is embedded in one side of the inner cavity of the anti-collision beam, and a plurality of air pipes are installed at the air delivery end of the miniature two-way air pump, and the air delivery pipes are respectively connected to the air valves to inflate the layered airbag.

[0006] Preferably, a rotating tube is provided on the top of the top beam, and a rotor is installed in the rotating tube; an independently operated driving motor is installed next to the rotating tube, a driven gear is installed at the bottom of the rotating tube, a driving gear is installed on the driving motor, and the rotor is installed on the driving gear. The driving gear and the driven gear are engaged with each other, and the rotor is driven to rotate by the driving motor.

[0007] Preferably, the extension beam and the top beam are parallel to each other; a fixed plate is provided at the inner end of the extension beam, and a power supply box is installed on the fixed plate; the top beam and the extension beam are both honeycomb plates, and the inner cavities of the top beam and the extension beam are both provided with honeycomb holes, and the honeycomb holes are filled with polyurethane foam.

[0008] Preferably, the micro bidirectional air pump supplies air to the laminar airbag through the air pipe. After the laminar airbag is inflated, it supports the energy absorbing box and plays a good elastic supporting role.

[0009] Preferably, the energy absorption box cooperates with the shock-absorbing spring on the rear side to further improve the impact shock absorption effect; the micro two-way air pump can also extract the air in the laminar airbag and adjust the bulging state of the energy absorption box by the amount of inflation.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This solution transforms the traditional rigid wing's "hard impact resistance" into "flexible energy absorption" through a design of "structural reinforcement + multi-level buffering + dynamic adjustment," significantly improving the safety and structural durability of the drone in collision scenarios. The curved design of the anti-collision beam disperses the impact force, avoiding localized stress concentration. The hard rubber panel on the anti-collision beam surface and the flexible rubber panel inside form a "rigid-flexible" surface protection. The hard panel resists the initial impact, while the flexible pad cushions the subsequent impact, preventing direct damage to the internal structure. Shock-absorbing springs, energy-absorbing boxes, and layered airbags form a multi-stage buffer system, which gradually absorbs impact energy (elastic deformation-material plastic deformation-gas compression buffering), reducing structural damage.

[0015] Example

[0016] See also Figure 1-5 , the present invention provides the following technical solutions: A collision-proof UAV wing includes a top beam 1 and an anti-collision beam 2; a rotating tube 3 is provided on the top of the top beam 1, and a rotor is installed in the rotating tube 3; An independently operated drive motor is installed next to the rotating tube 3. A driven gear is installed at the bottom of the rotating tube 3. A driving gear is installed on the drive motor, and the rotor is installed on the driving gear. The driving gear and the driven gear are meshed with each other, and the rotor is driven by the drive motor to rotate. The drive motor is a remote-controlled motor and is synchronously controlled by the remote control terminal. The top beam 1 is symmetrically distributed along the central axis. The outer end of the top beam 1 is provided with an arc-shaped anti-collision beam 2, and the inner side of the bottom end of the anti-collision beam 2 is provided with an extension beam 4; The extension beam 4 is parallel to the top beam 1; a fixing plate 5 is provided at the inner end of the extension beam 4, and a power supply box 6 is installed on the fixing plate 5, which provides power to the drive motor and the micro bidirectional air pump 12; The top beam 1 and the extension beam 4 are both honeycomb profiles, and the inner cavities of the top beam 1 and the extension beam 4 are both provided with honeycomb holes 7. A high-strength Kevlar fiber reinforcement layer is laid inside the honeycomb holes 7, and the honeycomb holes 7 are filled with polyurethane foam. The surface of the anti-collision beam 2 is provided with an anti-collision panel 8, and the inner side of the anti-collision panel 8 is provided with a pad 9. The anti-collision panel 8 is a hard rubber panel, and the pad 9 is a flexible rubber panel; A plurality of shock-absorbing springs 11 are distributed in the inner cavity of the anti-collision beam 2, and an energy absorption box 10 is provided between the shock-absorbing spring 11 and the backing plate 9; The energy absorption box 10 is a hollow rubber block, and a layered airbag 14 is installed in the inner cavity of the energy absorption box 10, and an air valve 15 is installed inside the layered airbag 14; A micro two-way air pump 12 is embedded in one side of the inner cavity of the anti-collision beam 2. A plurality of air pipes 13 are installed at the air delivery end of the micro two-way air pump 12, and the air pipes 13 are respectively connected to the air valves 15. The micro two-way air pump 12 supplies air to the layered airbag 14 through the air pipes 13. After the layered airbag 14 is inflated, it supports the energy absorption box 10 and plays a good elastic support role. The energy absorption box 10 cooperates with the shock-absorbing spring 11 on the rear side to further improve the impact shock absorption effect. The anti-collision beam 2 has a good flexible anti-collision effect and has better toughness than traditional rigid components; The micro bidirectional air pump 12 can also pump out the air in the laminar airbag 14, adjusting the inflation state of the energy absorption box 10 by the amount of inflation. When the anti-collision beam 2 is hit, the internal energy absorption box 10 acts as an effective buffer, providing a flexible protection mechanism for the wing side, avoiding the irreversible impact caused by the traditional rigid structure. Working principle: The top beam 1 and extension beam 4 utilize a honeycomb profile. The inner honeycomb cells 7 are reinforced with high-strength Kevlar fibers and filled with polyurethane foam. This structure utilizes the mechanical properties of the honeycomb to disperse impact forces, while the Kevlar fibers enhance tensile strength and the polyurethane foam absorbs energy, minimizing structural deformation. The hard rubber panel (anti-collision panel 8) on the surface of the anti-collision beam 2 and the flexible rubber panel (pad 9) on the inside form a "rigid-flexible" surface protection. The hard panel resists the initial impact, while the flexible pad cushions the subsequent impact, preventing direct damage to the internal structure. The multiple shock-absorbing springs 11 in the inner cavity of the anti-collision beam 2 are first compressed during an impact, and absorb part of the energy through elastic deformation, thereby reducing the impact load; Dynamic buffering principle of the energy absorption box 10 and the layered airbag 14: the energy absorption box 10 is a hollow rubber block with a layered airbag 14 installed inside, and the air valve 15 is connected to the micro bidirectional air pump 12 through the air pipe 13.

[0017] Inflated state: The air pump inflates the layered airbag 14, which expands and supports the crash box 10, causing it to "bulge" and provide elastic support. During an impact, the layered airbag 14 contracts under pressure, causing the crash box 10 to deform accordingly. Energy absorption occurs through a combination of material plastic deformation and gas compression within the layered airbag 14.

[0018] Air volume adjustment: The micro bidirectional air pump 12 pumps air out of the laminar airbag 14, adjusting the stiffness of the crash box 10 by controlling the amount of air inflated. For example, more air can be added when higher cushioning performance is required, while less air can be added when weight is reduced or to accommodate mild impacts, achieving a dynamically adjustable cushioning effect. Traditional wing rigid components are prone to irreversible deformation (such as breakage and bending) after impact, while this solution achieves flexible protection.
