Description

Technical Field

[0001] This utility model relates to the field of drone collision protection technology, and in particular to a drone collision protection structure. Background Technology

[0002] The background technology of drones mainly covers their design, development, and application needs, emphasizing their versatility and intelligent characteristics. Their core functions include navigation and positioning, communication transmission, and camera capture, and they are widely used in logistics, emergency rescue, and other fields. During operation, regular safety checks, data backups, and maintenance management are required to ensure the equipment operates normally and is used safely.

[0003] The lack of built-in collision protection in drones stems from limitations in their design and use. Relying on manual operation and real-time monitoring by external personnel, drones fail to fully address safety issues in flight. This lack of collision protection significantly increases the risk of accidents in real-world applications, potentially leading to serious equipment damage and impacting the safety and reliability of drone applications.

[0004] In response to this technical problem, this application proposes a drone collision protection structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a collision protection structure for unmanned aerial vehicles (UAVs). Through a dual buffer mechanism, it effectively decomposes external forces, significantly improves the collision protection effect, ensures the safety of the aircraft, and drives the support plate to raise the bird deterrent. At the same time, the connecting plate and the retractable plate unfold to both sides, fully exposing the bird deterrent. The bird deterrent emits multi-frequency sound waves to effectively disperse birds in front, avoid collisions, and ensure flight safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A collision protection structure for a drone includes a body, with support frames fixedly connected to the left and right sides of the bottom of the body, a protective shell fixedly connected to the top of the body, a bidirectional motor fixedly connected to the bottom of the inner wall of the protective shell, and bird deterrents connected to the front and rear driving ends of the bidirectional motor via bird deterrent components. Connecting frames are fixedly connected to the left and right sides of the body, and collision protection frames are connected to the inner walls of the connecting frames via protective components.

[0008] Furthermore, the bird deterrent assembly includes toothed plates that are rotatably connected to both the left and right sides of the front and rear ends of the inner wall of the protective shell. The outer walls of the toothed plates at the left and right ends mesh with each other, and the driving ends of the bidirectional motor at the front and rear ends are respectively fixedly connected to the opposite end of the right toothed plate.

[0009] Furthermore, each of the toothed plates is rotatably connected to a connecting plate at one of its opposite ends, and each of the connecting plates is rotatably connected to a shrink plate at one of its opposite ends.

[0010] Furthermore, the front and rear sides of the opposite end of the shrink plate are rotatably connected to a second connecting plate, and the bottom end of the second connecting plate is rotatably connected to the inner wall of the protective shell.

[0011] Furthermore, each of the toothed plates is rotatably connected to a support plate one at one end, and each of the support plates one is rotatably connected to a support plate two at the top, with the tops of the support plates two respectively rotatably connected to the four corners of the bottom of the bird repeller.

[0012] Furthermore, the protective component includes a spring that is fixedly connected to one end of the anti-collision frame, and the opposite end of the spring is fixedly connected to the inner wall of the machine body.

[0013] Furthermore, the front and rear ends of the anti-collision frame are rotatably connected to traction rods, and the opposite ends of the traction rods are slidably connected to connecting shells. The opposite ends of the connecting shells are rotatably connected to the front and rear ends of the inner wall of the connecting frame, respectively.

[0014] Furthermore, a second spring is sleeved on the outer wall of the traction rod, and one end of the second spring is in close contact with the other end of the inner wall of the connecting shell.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when a drone encounters a collision during flight, the anti-collision frame first decomposes the external force and retracts within the connecting frame. The built-in spring one disperses the compressive force, while spring two moves within the connecting shell through the traction rod to counteract the rebound force of spring one. This dual buffering mechanism effectively decomposes the external force, significantly improves the anti-collision effect, and ensures the safety of the aircraft.

[0017] 2. In this utility model, when the drone detects a flock of birds, the bidirectional motor drives the toothed plate to rotate, which in turn drives the support plate to raise the bird deterrent. At the same time, the connecting plate and the retractable plate unfold to both sides, fully exposing the bird deterrent. The bird deterrent emits multi-frequency sound waves to effectively disperse the birds in front, avoid collisions, and ensure flight safety. Attached Figure Description

[0026] 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.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a drone anti-collision protection structure, including a body 1. Support frames 3 are fixedly connected to the left and right sides of the bottom of the body 1. A protective shell 2 is fixedly connected to the top of the body 1. A bidirectional motor 8 is fixedly connected to the bottom of the inner wall of the protective shell 2. The front and rear drive ends of the bidirectional motor 8 are connected to a bird deterrent device 6 via a bird deterrent assembly. The bird deterrent assembly includes toothed plates 9 rotatably connected to the left and right sides of the front and rear ends of the inner wall of the protective shell 2. The outer walls of the left and right toothed plates 9 mesh with each other. The front and rear drive ends of the bidirectional motor 8 are respectively fixedly connected to the opposite ends of the right toothed plate 9. A connecting plate 11 is rotatably connected to the opposite ends of the toothed plates 9. (Refer to...) Figure 4 Each of the connecting plates 11 is rotatably connected to a shrink plate 5 at one end. Each of the shrink plates 5 is rotatably connected to a connecting plate 2 13 on both the front and back sides at the opposite end. The bottom of the connecting plate 2 13 is rotatably connected to the inner wall of the protective shell 2. Each of the toothed plates 9 is rotatably connected to a support plate 10 at one end. Each of the support plates 10 is rotatably connected to a support plate 2 12 at the top. The top of the support plate 2 12 is rotatably connected to the four corners at the bottom of the bird repeller 6.

[0028] Specifically: In the anti-collision protection structure of the UAV, when the airframe 1 encounters an external force collision during flight, the anti-collision frame 7, as the first line of defense, first decomposes the external force to reduce the direct impact on the airframe. The anti-collision frame 7 is designed with a retractable mechanism in the connecting frame 4. When an external force is applied to the anti-collision frame 7, it will retract along the inner wall of the connecting frame 4. In this process, the spring-14 plays a key role. The spring-14 effectively disperses the compressive force borne by the anti-collision frame 7 through its elastic properties, thereby avoiding local stress concentration and reducing damage to the airframe structure.

[0029] As the crash barrier 7 contracts, spring 14 generates a rebound force after reaching its compression limit. At this point, spring 2 17 moves within the connecting shell 15 via the traction rod 16. This design cleverly utilizes the elasticity of spring 2 17 to counteract the rebound force of spring 14. This synergistic operation of the dual spring system not only effectively balances the impact of external forces but also ensures that the crash barrier 7 can quickly return to its original position after being subjected to force, preparing for the next possible collision.

[0030] The entire collision protection structure, through the precise coordination of components such as the collision shield 7, spring 14, spring 2 17, traction rod 16, and connecting shell 15, achieves multi-level decomposition and buffering of external forces, significantly improving the collision avoidance effect of the UAV. This structure not only enhances the flight safety of the UAV in complex environments but also provides strong protection for the stability and reliability of the UAV in emergency situations.

[0031] Reference Figure 5 and Figure 6 Both ends of the body 1 are fixedly connected to the connecting frame 4. The inner wall of the connecting frame 4 is connected to the anti-collision frame 7 through the protective component. The protective component includes a spring 14 fixedly connected to the opposite end of the anti-collision frame 7. The opposite end of the spring 14 is fixedly connected to the inner wall of the body 1. Both ends of the anti-collision frame 7 are rotatably connected to the traction rod 16. The opposite ends of the traction rod 16 are slidably connected to the connecting shell 15. The opposite ends of the connecting shell 15 are rotatably connected to the front and rear ends of the inner wall of the connecting frame 4. The outer wall of the traction rod 16 is fitted with a spring 17. The opposite end of the spring 17 is in close contact with the opposite end of the inner wall of the connecting shell 15.

[0032] Specifically: In the bird deterrence module design of the UAV collision avoidance protection structure, when the sensor detects a flock of birds threatening the front of the UAV 1, the system immediately activates the bidirectional motor 8. This motor drives the gear plate 9 to rotate forward via a precision gear set. The rotation of the gear plate 9 pulls the support plate 10 through the hinge structure at its end, causing it to rise upward around the axis. The upward movement of the support plate 10 pulls the parallel support plate 12 to rise synchronously via a linkage pin, thereby driving the bird deterrent 6 fixed to the top of the support plate 12 to rise smoothly from the hidden compartment of the UAV 1.

[0033] Meanwhile, the connecting plate 11, fixed to the side wing of the support plate 10, moves upward as the support plate is raised. Through hinged engagement with the connecting plate 13, the bottom end of the connecting plate 13 is fixed to the inside of the retractable plate 5, forming a four-bar linkage. This linkage device enables the originally stacked left and right retractable plates 5 to overcome the track friction and simultaneously unfold along the slide groove to both sides of the body 1. When the retractable plates 5 are fully unfolded, a horn-shaped sound amplification channel is formed, completely exposing the ultrasonic generator and infrasonic generator integrated in the bird deterrent 6 to the outside of the body 1.

[0034] The fully deployed bird deterrent 6 immediately initiates a multi-frequency sound wave emission program: on the one hand, it stimulates the bird's auditory system with high-frequency ultrasound (20-25kHz), and on the other hand, it emits low-frequency infrasound waves (<20Hz) to interfere with the bird's sense of direction. The sound wave coverage area spreads to a 120-degree fan-shaped area in front of the fuselage 1 along the horn-shaped structure, effectively dispersing flocks of birds within 50 meters in front of the flight path. This active protection mechanism greatly reduces the probability of birds colliding with the fuselage 1, avoiding structural damage to the fuselage 1, sensor failure, or crashes caused by bird strikes, and significantly improving the safety of low-altitude flight. After the threat is eliminated, the entire system automatically retracts by reversing the motor. During the reset process, the reverse rotation of the toothed plate 9 retracts the bird deterrent 6 into the belly of the aircraft through the lever structure of the support plates 10 and 12. At the same time, the connecting plates 11 and 13 drive the retraction plate 5 to close again, ensuring the integrity of the aerodynamic shape.

[0035] Working principle: When the aircraft 1 encounters an external collision during flight, the anti-collision frame 7 decomposes the external force. When the anti-collision frame 7 retracts within the connecting frame 4 under the impact of the external force, the spring 14 disperses the compressive force on the anti-collision frame 7. When the spring 14 rebounds, the spring 2 17 moves within the connecting shell 15 through the traction rod 16, thus offsetting the rebound force of the spring 14, thereby completing the decomposition of the external force and improving the anti-collision effect of the device. When the aircraft 1 encounters a flock of birds, the bidirectional motor 8 is activated to drive the toothed plate 9 to rotate. This allows the toothed plate 9 to drive the support plate 2 12 through the support plate 10, raising the bird deterrent 6. With the cooperation of the connecting plate 2 13, the connecting plate 11 allows the retractable plate 5 to unfold to both sides, so that the bird deterrent 6 can be properly exposed outside the aircraft 1, allowing the bird deterrent 6 to generate bird deterrent sound waves, preventing birds from colliding with the aircraft 1 and protecting the aircraft 1.
