Embodiment 1

[0027] Such as Figure 1 to Figure 5 As shown, an aircraft mainly includes a fuselage a, an arm assembly b, and a rotor power assembly c. The fuselage a includes a shell 1 formed of a plate-shaped material with a containing cavity inside, and the shell The body 1 is provided with a cavity 11 recessed in the wall surface, the arm assembly b is hinged to the cavity 11 to form a folding arm structure, the rotor power assembly c is arranged on the arm assembly b, and the A foldable landing gear d is also provided on the arm assembly b;

[0028] The shell 1, the arm assembly b is specifically processed and formed by carbon fiber composite material. The carbon fiber composite material has excellent mechanical properties, its specific gravity is small, the rigidity is high, the strength is high, and the comprehensive indicators of specific strength and specific modulus are high, so as to protect the shell 1, The arm assembly b has excellent structural strength, so that the fuselage a a...

Embodiment 2

[0042] Such as Image 6 As shown, the rotating assembly 3 mainly includes a rotating angle piece 31, an angle positioning piece 32 that rotates relative to the rotating angle piece 31, and an articulated locking mechanism that operates between a locked position and an unlocked position. The rotating angle piece 31, an angle positioning piece 32 is connected to the two parts that need to be hinged separately. In this embodiment, the turning angle piece 31 is fixed to the folding arm b2, and the angle positioning piece 32 is fixed to the main arm b1, so that the folding arm b2 is fixed to the main arm b1. They can be rotated relative to each other through the connection of the rotating assembly 3. The rotating angle member 31 is provided with two sets of engaging portions 311 at intervals in the rotating circumferential direction, one of which is the angle position in the collapsed state, and the other is the unfolded state. The angle positioning member 32 is provided with a posit...

Embodiment 3

[0045] Such as Figure 7 As shown, the rotating assembly 3 mainly includes a rotating angle piece 31, an angle positioning piece 32 that rotates relative to the rotating angle piece 31, and an articulated locking mechanism that operates between a locked position and an unlocked position. The rotating angle piece 31, an angle positioning piece 32 is respectively connected with the two parts that need to be hinged. The rotation angle member 31 is provided with two sets of engaging parts 311 at intervals in the rotation circumferential direction, one of which is the angle position in the collapsed state, and the other is in the unfolded state. The angle positioning member 32 is provided with a positioning portion 321 that cooperates with the engaging portion 311. When the rotation angle member 31 and the angle positioning member 32 rotate relative to each other, the positioning portion 321 engages with different angular positions When the part 311 is matched, the rotation angle pos...

Abstract

The invention discloses a rotation assembly. The rotation assembly comprises a rotation angle piece, an angle positioning piece rotating relative to the rotation angle piece, and a hinge locking mechanism acting between a locking position and an unlocking position. At least one clamping part is arranged on the rotation angle piece in the rotating circumferential direction at intervals, a positioning part matched with the clamping part is arranged on the angle positioning piece, and when the hinge locking mechanism is located at the locking position, the positioning part and the clamping part are kept in a matched state. The rotation assembly is simple and compact in structure, good in rotating stability, high in precision and capable of reliably locking the rotating state, that is, the aircraft is kept in the unfolded state and the folded state stably without displacement, so that the flight stability and safety are guaranteed, the stability of the folded state is guaranteed, and the safety and reliability of the rotation assembly in the placing and transporting process are guaranteed.

Description

Technical field [0001] The invention relates to the technical field of aircraft, in particular to a rotating assembly. Background technique [0002] In the field of aircraft, especially unmanned aerial vehicles, a folding structure is usually used. The arms are unfolded when needed for flight, and can be folded and folded when needed for storage and transportation, which reduces the occupied space, facilitates storage, and improves space utilization. , Reduce transportation costs. However, the rotating and folding mechanisms that are often used at present have inaccurate rotation angles, low reliability in use, and difficult to stably maintain a stable expanded or folded state, and the folding mechanism is likely to shift during flight or storage, resulting in Unstable flight status is prone to damage to the drone, and it can also cause the drone to accidentally unfold when it is stored and be touched and cause damage. Summary of the invention [0003] The technical problem to b...
