Document Type and Number:
WIPO Patent Application WO/2019/061415
Kind Code:
A1
Abstract:
Disclosed are an unmanned aerial vehicle and a frame assembly thereof. The frame assembly of the unmanned aerial vehicle comprises a central frame, a first arm (10) and a second arm (20), wherein the first arm (10) is provided with a first cooperation portion (11), and the second arm (20) is provided with a second cooperation portion (21); the first arm (10) and the second arm (20) rotate relative to a support member (30), and the support member (30) is static in relation to the central frame; a locking member (40) is rotatably arranged on the support member (30); and a drive device (50) is used for driving the locking member (40) to rotate towards the first cooperation portion (11) and the second cooperation portion (21). When the first arm (10) rotates relative to the second arm (20) in a direction where the included angle therebetween increases until the first arm is in an unfolded state, the first cooperation portion (11) and the second cooperation portion (21) rotate to a pre-set locking position; and after the first cooperation portion (11) and the second cooperation portion (21) are located at the pre-set locking position, the drive device (50) drives the locking member (40) to rotate to the pre-set locking position and to lock the first cooperation portion (11) and the second cooperation portion (21), so as to prevent the first arm (10) and the second arm (20) from rotating in a direction where the included angle decreases.
