Description

Technical Field

[0001] The utility model belongs to the technical field of octorotor unmanned aerial vehicle frames, and in particular relates to a novel octorotor unmanned aerial vehicle frame assembly and a frame structure. Background Art

[0002] At present, multi-rotor UAVs have been widely used in some industries due to their advantages such as small size, high maneuverability, diversified mission payload and low cost. The frame of the multi-rotor UAV serves as a carrying platform. If the frame strength and rigidity are insufficient or the frame weight is too heavy, it will affect the flight performance of the rotor UAV, resulting in a decrease in practicality and even a crash.

[0003] At present, the existing traditional octorotor UAV has problems such as heavy frame, unreasonable arm design and excessive size; a reasonable frame structure can increase the flight time of the octorotor UAV, and reduce the weight of the octorotor UAV while ensuring the strength of the body itself, thereby increasing the mission duration; for octorotor UAVs with the same performance, a smaller size and a tighter layout structure can improve the portability of the octorotor UAV and reduce the occurrence of propeller-slapping accidents of the octorotor UAV.

[0004] Therefore, it is necessary to improve the existing eight-rotor UAV frame to make the eight-rotor UAV frame lighter and improve the flight performance and portability of the eight-rotor UAV without increasing the production cost too much. Utility Model Content

[0005] In order to overcome the problems existing in the background technology, the utility model provides a new type of octorotor UAV frame, which can improve the space utilization rate of the octorotor UAV; through reasonable design, the frame weight can be reduced, the flight performance can be improved, and the portability of the octorotor UAV can be improved.

[0006] In order to achieve the above purpose, the utility model is introduced in detail as follows:

[0007] A novel eight-rotor UAV frame, characterized in that: the novel eight-rotor UAV frame mainly comprises a carbon plate I, a carbon plate II, a fuselage connecting piece, an arm boom, an arm forearm, and a tripod, the carbon plate I and the carbon plate II are connected by bolts through the fuselage connecting piece, four rectangular holes and four pairs of fixing holes are provided at the four corners of the carbon plate I and the carbon plate II, a threading hole is provided in the middle of the carbon plate I and the carbon plate II, the arm boom is provided with 5 fixing holes for connecting the fuselage connecting piece, the arm boom is fixed between the carbon plate I and the carbon plate II by bolts through the fuselage connecting piece, two through holes are symmetrically provided on the connecting surface of the fuselage connecting piece and the carbon plate I and the carbon plate II, the through hole diameter matches the size of the fixing holes of the carbon plate I and the carbon plate II, the mounting holes of the tripod and the arm forearm are arranged at the lower end of the arm boom, and the through holes of the arm boom, the arm forearm, and the tripod are connected by bolts.

By improving the eight-rotor UAV frame, the space of the eight-rotor UAV is reasonably used to the maximum extent without increasing the volume; two motor fixing seats are reserved on a forearm of an arm, which supports the installation of up to sixteen motors, so that the eight-rotor UAV can obtain a larger load capacity and a stronger flight performance; the upper and lower dual-motor structure can offset the rotational torque brought by the propeller through forward and reverse rotation, and the arm does not need to be distinguished during installation; the path of the arm is optimized, the total length of the arm is reduced, and the weight of the frame can be reduced while ensuring the strength of the frame, and the wind resistance and power loss caused by the arm can be reduced.
