Title:
FOLDING PADDLE MECHANISM AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/098452
Kind Code:
A1
Abstract:
Disclosed are a folding paddle mechanism (10) and an unmanned aerial vehicle (100). The folding paddle mechanism (10) comprises a paddle clamp base (21), a paddle clamp upper cover (22), paddles (1), connecting shafts (33) and a damping device which is used for forming resistance to the rotation of the paddles (1). The paddle clamp upper cover (22) and the paddle clamp base (21) are arranged in a spaced manner; the paddles (1) each comprise a fixed end (11) and a free end (12); the fixed end (11) is clamped between the paddle clamp base (21) and the paddle clamp upper cover (22); the connecting shafts (33) are arranged in the paddle clamp base (21), the paddles (1) and the paddle clamp upper cover (22) in a penetrating manner; the connecting shafts (33) are fixedly connected to the fixed ends (11); the connecting shafts (33) are rotationally connected to the paddle clamp base (21) and the paddle clamp upper cover (22); the damping device comprises a shell (31) clamped between the paddle clamp base (21) and the fixed ends (11) and fixedly connected to the paddle clamp base (21), and a damping assembly mounted on the shell (31); and the connecting shafts (33) penetrate the damping assembly and are fixedly connected to the damping assembly. In the folding paddle structure (10), the resistance borne by the paddles (1) is adjusted by means of the damping assembly, such that vibrations caused by the change in the direction of rotation of the paddles (1) is prevented from being transmitted to a fuselage (20), and vibrations of an electric motor (40) are not transmitted to the paddles (1) after being transmitted to the paddle clamp base (21).
