Abstract:
Disclosed are an unmanned aerial vehicle and a frame assembly thereof. The frame assembly comprises a central frame, a first arm (10), a second arm (20), a synchronization device (30), a locking device (40) and a mounting base (50), wherein the first arm (10) and the second arm (20) rotate relative to the mounting base (50), and the mounting base (50) is static in relation to the central frame; the synchronization device (30) is arranged between the first arm (10) and the second arm (20), and the synchronization device (30) comprises a plurality of transmission members rotatable relative to each other, the plurality of transmission members rotating to enable the first arm (10) and the second arm (20) to synchronously rotate; the locking device (40) is used for locking at least one transmission member with a protruding portion (31) provided thereon, and the locking device (40) comprises an elastic abutting component (41); the elastic abutting component (41) abuts against the protruding portion (31) on the at least one transmission member in the synchronization device (30), so as to impede the rotation of the transmission member having the protruding portion (31); and when the transmission member having the protruding portion (31) overcomes, under the action of an external force, an elastic resistance applied by the elastic abutting component (41), the transmission member having the protruding portion (31) can continue to rotate.
