Description

Technical Field

[0001] This utility model relates to the technical field of multi-axis tilt-fixed-wing unmanned aerial vehicles (UAVs), and in particular to a multi-axis tilt-fixed-wing UAV. Background Technology

[0002] In recent years, with the rapid development of science and technology, and driven by the need to conserve human and material resources and protect human life, the application areas of drones have been continuously expanding, leading to the rapid development of the drone industry. Drones, with their high maneuverability, have a very broad application prospect in both military and civilian fields.

[0003] Among existing multi-axis tilt-fixed-wing UAVs, such as the multi-axis tilt-fixed-wing UAV disclosed in utility model patent application number 202021449250.0, this utility model can perform both fixed-wing and rotary-wing flight modes. This allows the multi-axis tilt-fixed-wing UAV to adapt to more flight missions and expands the application range of UAVs.

[0004] However, during the use of multi-rotor tilt-wing drones, the rotor blades may come into contact with people or objects during operation, resulting in injury. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-rotor tilt-fixed-wing UAV that, by setting up a body mechanism and a power mechanism, can provide all-round protection for the entire rotor during the use of the multi-rotor tilt-fixed-wing UAV, and uses replaceable parts of the fuselage as collision points to prevent injury to personnel and main equipment.

[0006] This utility model discloses a multi-axis tilt-rotor fixed-wing UAV, comprising a fuselage structure; it also includes two sets of power mechanisms, a rotation mechanism, a drive mechanism, and two sets of reversing mechanisms. The two sets of power mechanisms are mounted on the fuselage structure, the rotation mechanism is mounted inside the fuselage structure, the drive mechanism is mounted inside the fuselage structure, and the two sets of reversing mechanisms are mounted on the rotation mechanism and the drive mechanism, respectively. The UAV is driven by opening the drive mechanism, and the direction of power is changed by opening the rotation mechanism. Simultaneously, the reversing mechanisms work together to achieve bilateral symmetry. The power mechanism provides airflow for flight, and the fuselage structure provides balance. This allows the multi-axis tilt-rotor fixed-wing UAV to provide all-around protection for the entire rotor during use, and replaceable fuselage parts are used as collision points to prevent injury to personnel and key equipment.

[0007] Preferably, the airframe structure includes a fuselage, two sets of wings, two sets of elevators and a steering tail. The two sets of wings are mounted on the fuselage, the two sets of elevators are mounted on the fuselage, and the steering tail is mounted on the upper part of the fuselage. The fuselage flies through the wings and adjusts its attitude through the elevators and the steering tail.

[0008] Preferably, the power mechanism includes a rotor ring frame, a bevel gear ring, a rotor, and a first bevel gear. The rotor ring frame is rotatably mounted on the wing, the bevel gear ring is mounted on the rotor ring frame, the rotor is rotatably mounted on the rotor ring frame, and the first bevel gear is mounted on the rotor. The rotor ring frame is rotated by the bevel gear ring to adjust the wind direction, and the rotor is rotated by the first bevel gear to drive the power.

[0009] Preferably, the rotating mechanism includes a motor, a bevel gear, two sets of double bevel gear shafts, and two sets of double bevel gear shafts. The motor is installed inside the fuselage, the bevel gear is installed at the output end of the motor, and the two sets of double bevel gear shafts are rotatably installed on the fuselage, with both sets meshing with the bevel gears. A set of double bevel gear shafts is rotatably installed inside each wing, with each set of double bevel gear shafts meshing with a set of double bevel gear shafts, and each set of double bevel gear shafts meshing with a set of bevel gear rings. By turning on the motor, the bevel gears are driven to rotate. Simultaneously, the rotation of the bevel gears meshes with the double bevel gear shafts, causing the double bevel gear shafts to rotate. Simultaneously, the rotation of the double bevel gear shafts meshes with the double bevel gear shafts, causing the double bevel gear shafts to rotate. Simultaneously, the rotation of the double bevel gear shafts meshes with the bevel gear rings, causing the bevel gear rings to rotate.

[0010] Preferably, the drive mechanism includes a second motor, a third bevel gear, and two sets of double bevel gear shafts. The second motor is installed inside the machine body, the third bevel gear is installed at the output end of the second motor, and the two sets of double bevel gear shafts are rotatably installed on the machine body. Both sets of double bevel gear shafts mesh with the third bevel gear, and each set of double bevel gear shafts meshes with a first set of bevel gears. By turning on the second motor, the third bevel gear is driven to rotate. While the third bevel gear rotates, it meshes with the third bevel gear shaft, causing the third bevel gear shaft to rotate. While the third bevel gear shaft rotates, it meshes with the first bevel gear, causing the first bevel gear to rotate.

[0011] Preferably, the reversing mechanism includes two sets of bevel gears and a single bevel gear shaft. The two sets of bevel gears are mounted on a double bevel gear shaft and are disconnected from each other. The single bevel gear shaft is rotatably mounted inside the wing and meshes with the two sets of bevel gears. When the double bevel gear shaft rotates, the reversing mechanism is achieved by the bevel gears cooperating with the single bevel gear shaft for guidance, thereby making the drive on both sides of the device symmetrical and preventing imbalance during flight.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by opening the drive mechanism for driving, opening the rotation mechanism for changing the power direction, and cooperating with the reversing mechanism for bilateral symmetry, the power mechanism for wind-powered flight, and the body mechanism for balance, the multi-axis tilt fixed-wing UAV can be used to provide all-round protection for the entire rotor. Replaceable parts of the fuselage are used as collision points to prevent injury to personnel and main equipment. Attached Figure Description

The two sets of wings 12 are mounted on the fuselage 11, the two sets of elevator tail 13 are mounted on the fuselage 11, and the steering tail 14 is mounted on the upper part of the fuselage 11. The power mechanism 2 includes a rotor ring frame 21, a bevel gear ring 22, a rotor 23, and a bevel gear 24. The rotor ring frame 21 is rotatably mounted on the wing 12, the bevel gear ring 22 is mounted on the rotor ring frame 21, the rotor 23 is rotatably mounted on the rotor ring frame 21, and the bevel gear 24 is mounted on the rotor 23.

Both sets of double bevel gear shafts 43 mesh with the third bevel gear 42, and each set of double bevel gear shafts 43 meshes with a set of first bevel gears 24. The reversing mechanism 5 includes two sets of bevel gears 51 and a single bevel gear shaft 52. The two sets of bevel gears 51 are mounted on the double bevel gear shaft 33 and are disconnected from each other. The single bevel gear shaft 52 is rotatably mounted inside the wing 12 and meshes with the two sets of bevel gears 51. By activating motor 2 (41), bevel gear 3 (42) is driven to rotate. Simultaneously, bevel gear 3 (42) meshes with double bevel gear shaft 3 (43), causing double bevel gear shaft 3 (43) to rotate. Conversely, double bevel gear shaft 3 (43) meshes with bevel gear 1 (24), causing bevel gear 1 (24) to rotate. Bevel gear 1 (24) drives rotor 23 for power drive. Similarly, by activating motor 1 (31), bevel gear 2 (32) is driven to rotate. Simultaneously, bevel gear 2 (32) meshes with double bevel gear shaft 1 (33), causing double bevel gear shaft 1 (33) to rotate. Conversely, double bevel gear shaft 1 (33) meshes with double bevel gear shaft 2 (34), causing double bevel gear shaft 2 (34) to rotate. While the double bevel gear shaft 34 rotates, it meshes with the bevel gear ring 22, causing the bevel gear ring 22 to rotate. The bevel gear ring 22 drives the rotor ring frame 21 to rotate for wind direction adjustment. At the same time, when the double bevel gear shaft 33 rotates, the bevel gear 4 51 cooperates with the single bevel gear shaft 52 to achieve reverse rotation, thereby making the drive on both sides of the equipment symmetrical and preventing imbalance during flight. The fuselage 11 is propelled by the wing 12, and the attitude is adjusted by the elevator tail 13 and the steering tail 14. Thus, during the use of the multi-axis tilt-rotor fixed-wing UAV, the entire rotor can be protected in all directions. Replaceable parts of the fuselage are used as collision points to prevent injury to personnel and main equipment.

Simultaneously, bevel gear 3 (42) meshes with double bevel gear shaft 3 (43), causing double bevel gear shaft 3 (43) to rotate. Conversely, double bevel gear shaft 3 (43) meshes with bevel gear 1 (24), causing bevel gear 1 (24) to rotate. Bevel gear 1 (24) drives rotor 23 for power drive. Motor 1 (31) drives bevel gear 2 (32), causing it to rotate. Simultaneously, bevel gear 2 (32) meshes with double bevel gear shaft 1 (33), causing double bevel gear 2 (24) to rotate. The first bevel gear shaft 33 rotates, and at the same time, the first bevel gear shaft 33 rotates and meshes with the second bevel gear shaft 34, causing the second bevel gear shaft 34 to rotate. At the same time, the second bevel gear shaft 34 rotates and meshes with the bevel gear ring 22, causing the bevel gear ring 22 to rotate. The bevel gear ring 22 drives the rotor ring frame 21 to rotate to adjust the wind direction. At the same time, when the first bevel gear shaft 33 rotates, the fourth bevel gear 51 cooperates with the single bevel gear shaft 52 to achieve reverse rotation, so that the drive on both sides of the equipment is symmetrical, preventing imbalance during flight. The fuselage 11 is propelled into flight by the wing 12, and the attitude is adjusted by the elevator tail 13 in cooperation with the steering tail 14.
