Embodiment Construction
[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0039] The present invention provides a foldable paddle arm assembly, see Figure 1 to Figure 22 , the foldable paddle arm assembly includes a base 100 and a paddle arm 200, the paddle arm 200 is pivotally connected to the base 100 and has an unfolded state and a folded state, the paddle arm 200 is located in the same plane or substantially on the same plane when the paddle arm 200 is in the unfolded state, the paddle arm 200 is in the unfolded state. When the arm 200 is in the folded state, it is folded toward the center of the base 100, wherein the base 100 can be the fuselage of the drone. The board 120, in addition, the base 100 further includes a mounting seat located between the first board 110 and the second board 120 to connect the two, the mounting seat 400 can be respectively connected with the first b...

The invention discloses a foldable propeller arm assembly. The foldable propeller arm assembly comprises a base and propeller arms, wherein the propeller arms are pivoted on the base and have an unfolded state and a folded state; a first clamping and connecting part near the base is arranged on each propeller arm. The foldable propeller arm assembly also comprises first locking elements which are rotationally connected with the base; a second clamping and connecting part is arranged on each of the first locking elements; and the first locking elements are used for rotating to engage the second clamping and connecting parts with the first clamping and connecting parts when the propeller arms are in the unfolded state and are in an abutted position limiting state with the base, so that the propeller arms maintain the unfolded state. The invention also discloses an unmanned aerial vehicle. The propeller arms adopt an integral pivoting structure, so that the integral strength and rigidity of the propeller arms are effectively ensured; the integral structure stability of the unmanned aerial vehicle is enhanced; and meanwhile, the propeller arms can be folded and unfolded, so that the occupied space of the unmanned aerial vehicle when the unmanned aerial vehicle is not used is greatly reduced. The technical scheme provided by the invention has the characteristics that the structure is simple, the operation is simple and convenient, and the like. The operation convenience of the propeller arms is greatly improved.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a foldable paddle arm assembly and an unmanned aerial vehicle. Background technique [0002] The paddle arm of a common rotary-wing UAV is generally composed of two detachable parts. The first part close to the fuselage of the UAV is usually integrally formed with the fuselage, and the second part far from the fuselage of the UAV passes through. The detachable structure is attached to the first section, thereby reducing the space occupied by the drone during packaging and transportation. However, the existing detachable structure of the paddle arm usually completely separates the two segments of the paddle arm, so the assembly process is complicated, inefficient, and inconvenient. Especially when the specifications of each paddle arm are inconsistent, there is still a problem of difficulty in pairing. SUMMARY OF THE INVENTION [0003] The main purpose of the p...
