Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to an unmanned aerial vehicle (UAV). Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, have demonstrated immense value in numerous fields, including aerial surveying, agricultural plant protection, logistics and transportation, emergency rescue, and military reconnaissance, thanks to their flexible maneuverability and wide range of applications. Multi-rotor UAVs, with their simple structure, stable operation, and vertical takeoff and landing capabilities, have become the mainstream configuration in the current civilian UAV market.

[0003] Traditional multi-rotor drones typically have rotors symmetrically arranged around a central support, with flight attitude adjusted by controlling the rotational speed of different rotors. However, this conventional layout has some inherent limitations. First, its structural layout is often relatively fixed, with limited scalability. When adding rotors to increase payload or improve flight stability, it usually means a significant increase in overall size, which not only increases the difficulty of storage and transportation but may also affect its maneuverability in complex environments. Second, in a conventional layout, the lift vector generated by the rotors is unidirectional, mainly concentrated in the vertical direction. When dealing with sudden airflow or performing tasks requiring high maneuverability, there is still room for improvement in the response speed and efficiency of attitude adjustment.

[0004] Furthermore, in pursuit of stability, some existing multi-rotor UAVs employ cross-shaped or simple radial connection structures. These structures may not distribute stress evenly, especially under lateral impacts, where stress tends to concentrate at a few connection points, affecting overall structural strength and flight stability. Simultaneously, traditional power systems typically equip each rotor with an independent motor, and the rotor plane is fixed. This results in relatively limited aerodynamic efficiency and control methods, making it difficult to achieve optimal energy consumption and control performance under complex flight conditions. Summary of the Invention

[0005] This invention provides a drone to solve the problems of poor expandability, insufficient structural stability, and limited maneuverability of existing drones mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A drone, comprising: A connecting bracket, comprising a polygonal connecting plate and supporting legs, wherein the supporting legs are fixed to the polygonal connecting plate. A connecting rod, wherein multiple connecting rods are provided; the connecting rods are fixedly mounted on the connecting bracket and their axes coincide with the diagonal of the polygonal connecting disc; a rotating wing assembly is provided on the connecting rod; A power supply device is mounted on a connecting bracket and electrically connected to the rotor assembly.

[0007] Furthermore, the rotating wing assembly includes a support base, a first rotating motor, and a second rotating motor. The support base is disposed at one end of the connecting rod. The first rotating motor and the second rotating motor are mirror-symmetrically disposed on the support base. The main shafts of the first rotating motor and the second rotating motor are provided with support plates. The support plates are provided with a first connecting shaft and a second connecting shaft. The rotating wing is disposed on the first connecting shaft and the second connecting shaft.

[0008] Furthermore, the periphery of the polygonal connecting disc has a hollowed-out structure.

[0009] Furthermore, the polygonal connecting disk has a regular octagonal shape.

[0010] Furthermore, the connecting rod has a hollow structure, and one end of the connecting rod extends toward the center of the polygonal connecting disc.

[0011] Furthermore, the power supply device is a storage battery, which is electrically connected to the first rotary motor and the second rotary motor.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. Optimized structural layout and excellent expandability: By employing a polygonal connecting plate and arranging the connecting rods along its diagonal, a stable and symmetrical force-bearing structure is formed. This design allows for easy expansion of the connecting rods and rotors by increasing the number of sides of the connecting plate (e.g., from hexagonal to octagonal) when needed, without significantly increasing the overall core size, thus enhancing the platform's expandability.

[0013] 2. Enhanced Structural Stability and Strength: The connecting rods are arranged diagonally, forming a uniformly stressed frame structure together with the polygonal connecting disc, effectively improving the rigidity and impact resistance of the fuselage. The hollowed-out design of the connecting disc reduces weight while maintaining strength. The support legs ensure smooth takeoff and landing of the drone.

[0014] 3. Enhanced flight maneuverability and control efficiency: Each connecting rod is equipped with two mirror-symmetrical rotary motors at its end, which can independently control the rotor blades on it. This layout not only provides ample lift but also allows for faster roll, pitch, and other attitude adjustments through differential control, and even possesses a certain potential for vector thrust, thereby significantly improving the UAV's maneuverability and anti-jamming capabilities.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] This embodiment provides a drone, such as Figures 1-2 As shown, it includes: A connecting bracket, comprising a polygonal connecting plate 1 and a support leg 2, wherein the support leg 2 is fixed on the polygonal connecting plate 1; Connecting rod 3, multiple connecting rods 3 are provided; the connecting rod 3 is fixedly mounted on the connecting bracket and its axis coincides with the diagonal of the polygonal connecting disk 1; a rotating wing assembly is provided on the connecting rod 3; A power supply device is mounted on a connecting bracket and electrically connected to the rotor assembly.

[0020] Further optimizing the above embodiment, the rotary wing assembly includes a support base 4, a first rotary motor 5, and a second rotary motor 6. The support base 4 is disposed at one end of the connecting rod 3. The first rotary motor 5 and the second rotary motor 6 are mirror-symmetrically arranged on the support base 4. The main shafts of the first rotary motor 5 and the second rotary motor 6 are provided with support plates 7. The support plates 7 are provided with a first connecting shaft 8 and a second connecting shaft 9. Rotary wings 10 are disposed on the first connecting shaft 8 and the second connecting shaft 9. Each connecting rod 3 has two independent rotary motors (first and second rotary motors) at its end, each motor driving a pair of rotary wings. This design means that even if one motor fails, the other motor can still operate, providing basic safety redundancy. Furthermore, it enables differential speed control of different rotary wings, providing additional roll control torque for the UAV, making attitude adjustments faster and more precise.

[0021] In a further optimization of the above embodiment, the periphery of the polygonal connecting disk 1 is designed with a hollow structure. This hollow structure reduces air resistance on the central body of the drone during flight, especially during translational movement or when encountering crosswinds, and also reduces the overall weight.

[0022] Further optimizing the above embodiment, the polygonal connecting plate 1 has a regular octagonal structure. This structural arrangement provides four diagonal directions for installing power units, with a sufficient number and reasonable distribution. It can meet the load-bearing and stability requirements of most application scenarios without making the structure complex and bulky due to an excessive number of sides.

[0023] In a further optimization of the above embodiment, the connecting rod 3 is a hollow structure, with one end extending towards the center of the polygonal connecting disc 1. The hollow structure provides a natural, protected channel for the wires from the central power supply device to the end motor, avoiding the problems of tangling, wear, and wind resistance that may result from exposed cables.

[0024] In a further optimization of the above embodiment, the power supply device is a storage battery, which is electrically connected to the first rotary motor 5 and the second rotary motor 6. By mounting the storage battery on a connecting bracket, rather than supplying power through external wires, the self-sustaining flight capability and portability of the drone are ensured.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
