Technical Field

[0001] This utility model relates to the field of aircraft technology, and in particular to aircraft separation anti-collision propeller shafts. Background Technology

[0002] With the rapid development of the low-altitude economy, aircraft are increasingly widely used in logistics distribution, emergency rescue, urban air traffic and other fields. During flight, the propeller shaft is prone to collision with other components and obstacles. The aircraft separation anti-collision propeller shaft design is a key technology to ensure that multi-rotor aircraft avoid collisions between the propeller and the fuselage, other components or the surrounding environment when they are separated or folded.

[0003] Existing aircraft anti-collision propeller shaft structures are relatively simple, lacking in impact resistance, with limited protection range. They easily overlook obstacles on the sides and above, have low shock absorption capacity, and use fixed connection methods. When the protective components are damaged, disassembly and assembly require special tools, resulting in time-consuming and costly maintenance.

[0004] Therefore, in view of the problems of limited protection range, inconvenient disassembly and assembly, and time-consuming maintenance of existing aircraft separation anti-collision propeller shafts, an aircraft separation anti-collision propeller shaft can be designed. Utility Model Content

The propeller 8 rotates to drive the aircraft into flight. The camera 4 captures videos and photos, recording the flight process. The support frame 6 provides support during takeoff and landing. The anti-collision shield 9 reduces the probability of direct collision between the propeller 8 and obstacles, increases the lifespan of the propeller 8, and provides a large protection range. After the flight ends, press the two connecting posts 10 of the damaged set of the anti-collision shield 9 to move it toward the connecting rod 7, separating the anti-collision shield 9 and the connecting rod 7. Replace with a new anti-collision shield 9. The magnetic plate 11 automatically adheres and aligns when it approaches the connecting rod 7, assisting in fixation, increasing stability, and reducing manual adjustment time. Release the connecting post 10 to move it toward the anti-collision shield 9, thus achieving the installation and fixation of the anti-collision shield 9 and the connecting rod 7. The overall assembly and disassembly are convenient, reducing maintenance costs and providing high compatibility.

[0024] Please see Figure 1 , Figure 3 and Figure 4In this embodiment, a solar panel 12 and an infrared sensor 13 are fixedly connected to the upper end of the aircraft fuselage 1. The solar panel 12, the infrared sensor 13, and the camera 4 are all electrically connected to the controller 2. The solar panel 12 improves power generation efficiency and reduces energy consumption. The infrared sensor 13 monitors the distance of obstacles around the propeller 8 in real time. A shock-absorbing pad 14 is fixedly connected to the lower end of the aircraft fuselage 1. There are two sets of symmetrical arms 5 on the left and right sides, and two sets of symmetrical arms 5 on the front and back of each set. The lower end of the support frame 6 is fixedly connected to the same shock-absorbing pad 14. The shock-absorbing pad 14 absorbs the impact force of take-off and landing and increases the stability of take-off and landing. A brushless motor 15 is fixedly connected to the upper end of the support frame 6. The output shaft of the brushless motor 15 is fixedly connected to the propeller 8.

Support frame 6 provides support during takeoff and landing. Anti-collision shield 9 offers a large protection range. After flight, pressing the two connecting posts 10 of the damaged set of anti-collision shield 9 causes the connecting posts 10 to move towards adjustment groove 16 and compress spring 17, separating anti-collision shield 9 from connecting rod 7. A new anti-collision shield 9 is then replaced. Magnetic suction plate 11 automatically adheres to and aligns with connecting rod 7, assisting in fixation.
