[0002] Unmanned aerial vehicles (UAVs), also known as drones, are aircraft controlled by radio remote control equipment and onboard program control devices, or aircraft operated autonomously, either completely or intermittently, by onboard computers. With technological advancements and the promotion of the low-altitude economy, the demand for UAVs, especially small UAVs, is increasing across various industries, and the research and development of UAVs for different scenarios is constantly evolving. Common UAVs include unmanned fixed-wing aircraft, unmanned vertical takeoff and landing (VTOL) aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders. Tiltrotor UAVs are a type of UAV that combines VTOL and fixed-wing high-speed cruise capabilities, switching flight modes by changing the angle of the rotor or wing. In the education field, learning to design and manufacture tiltrotor UAVs requires verifying different tilting mechanisms and power mechanisms. Traditional aircraft are relatively closed, monolithic structures, necessitating the purchase or manufacture of the entire UAV during the verification of different structures, resulting in high costs and significant time consumption.

Detailed Implementation

[0021] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] Example 1

[0023] Refer to 1 to Figure 3 This utility model provides a tilting structure for a drone, including a tilting connecting arm 1, a rotating base 2 connected to one end of the tilting connecting arm 1, a drive mechanism 3 mounted on the tilting connecting arm 1 for driving the rotating base 2 to rotate, and a plug-in base 4 detachably connected to the other end of the tilting connecting arm 1. The plug-in base 4 is specifically connected to the main body of the drone. The tilting connecting arm 1 and the plug-in base 4 are detachably connected, allowing for quick disassembly and assembly during teaching and verification processes to replace different types of tilting structures (such as different transmission mechanisms or hardware specifications). The tilting connecting arm 1, rotating base 2, and plug-in base 4 can be made of materials such as aluminum alloy, plastic, or carbon fiber, depending on actual needs.

[0024] The tilting connecting arm 1 is the main support component of the entire tilting structure, capable of bearing the weight of the UAV power assembly and the load during flight. The tilting connecting arm 1 includes an arm portion 11, a connecting seat 12 disposed at one end of the arm portion 11, and a rotating seat 2 connected to the other end of the arm portion 11. The connecting seat 12 is provided with a insertion groove 13 for connecting the insertion seat 4, and the insertion seat 4 is provided with an insertion part 41 that mates with the insertion groove 13. In this embodiment, the upper end of the insertion groove 13 penetrates through the end face of the connecting seat 12, while the lower end of the insertion groove 13 is closed. When the insertion seat 4 and the connecting seat 12 are connected, the insertion part 41 is installed in place when it contacts the lower end of the insertion groove 13.

[0025] Each of the two opposing side walls of the insertion slot 13 is provided with a first protrusion 14, and the side of the insertion part 41 is provided with a first groove 42 that mates with the protrusion. The cooperation between the first protrusion 14 and the first groove 42 can provide good positioning and guidance, and also ensure the connection strength between the insertion seat 4 and the connecting seat 12. The number of first protrusions 14 and first grooves 42 can be adjusted according to actual needs, such as providing two or three sets of symmetrical first protrusions 14 and first grooves 42 to further improve the stability of the connection. In this embodiment, the cross-sectional shape of the first protrusion 14 is trapezoidal, and the matching first groove 42 is also a trapezoidal groove. The hypotenuse of the trapezoid can provide lateral constraint force, effectively preventing the insertion part 41 from shaking in the horizontal direction. Of course, the shapes of the first protrusion 14 and the first groove 42 can also be designed as other shapes, such as dovetail or T-shaped, which can also achieve reliable connection and convenient assembly and disassembly.

[0026] The protrusion and the bottom surface of the insertion groove 13 form a second groove 15, and the side of the insertion part 41 is provided with a second protrusion 43 that mates with the second groove 15. Similarly, the cooperation between the second protrusion 43 and the second groove 15 can not only play a good positioning and guiding role, but also ensure the connection strength between the insertion seat 4 and the connecting seat 12.

[0027] The top surface of the connector 12 is provided with a recess 16, which communicates with the insertion slot 13. The insertion part 41 is provided with a connecting part 44 that mates with the recess 16. Specifically, the connecting part 44 can be embedded in the recess 16, and the top surface of the connecting part 44 and the top surface of the connector 12 are on the same plane, ensuring the uniformity and smoothness of the overall structure.

[0028] The bottom surface of the recessed portion 16 is provided with a first mounting hole 17, and the connecting portion 44 is provided with a second mounting hole 45 that mates with the first mounting hole 17. The first mounting hole 17 is provided with an internal thread, and the second mounting hole 45 is a countersunk hole. After the insertion portion 41 is inserted into the recessed portion 16, the connecting portion 44 and the recessed portion 16 can be connected and fixed using screws. Through the mating of the connecting portion 44 and the recessed portion 16, and the fixing method of the screws passing through the first mounting hole 17 and the second mounting hole 45, reliable fixing of the insertion seat 4 and the tilting connecting arm 1 is achieved, further improving the connection strength. During disassembly and assembly, the insertion portion 41 can be pulled out of the insertion slot 13 simply by removing the screws, making the operation simple and quick, and greatly improving maintenance efficiency.

[0029] The bottom surface of the insertion slot 13 is provided with a first connector 5, and the insertion part 41 is provided with a second connector that mates with the first connector 5. When the insertion part 41 is inserted into the insertion slot 13, the first connector 5 and the second connector are mated to achieve the transmission of power and signals. The first connector 5 and the second connector are waterproof connectors to ensure reliable transmission of power and signals. In addition, the tilting connecting arm 1 is also pre-wired to facilitate the transmission of power and control signals to the servo motor 31 and the power assembly.

[0030] The rotating base 2 includes a base body 21, and a first connector 22 and a second connector 23 arranged parallel to the bottom surface of the base body 21. The base body 21 is used to install the power components of the UAV (such as motors and propellers), and both the first connector 22 and the second connector 23 are provided with connecting holes, which can be used to install the rotating shaft.

[0031] The drive mechanism 3 includes a servo motor 31 mounted on the tilting connecting arm 1 and a gear set 32 ​​for connecting the servo motor 31 and the rotating base 2. The first connecting member 22 and the second connecting member 23 are both rotatably connected to the tilting connecting arm 1, and the gear set 32 ​​is connected to the first connecting member 22. Specifically, in this embodiment, the gear set 32 ​​includes a meshing drive gear and a driven gear, wherein the drive gear is connected to the output end of the servo motor 31, and the driven gear is connected to the first connecting member 22. The number of teeth on the drive gear and the number of teeth on the driven gear (i.e., the transmission ratio) can be set according to the actual torque requirement (weight of the power component) to meet the torque requirement for the rotating base 2 to drive the power component to tilt. The tilting connecting arm 1 has a pre-formed through portion, and the servo motor 31 is installed inside the through portion, with the output end of the servo motor 31 protruding outside the tilting connecting arm 1.

[0037] The top surface of the connector 12 is provided with a recess 16, which communicates with the insertion slot 13. The insertion part 41 is provided with a connecting part 44 that mates with the recess 16.
