WIPO Patent Application WO/2021/035631

A1

A quick release member (330), a propeller assembly (300), and a multi-rotor unmanned aerial vehicle. The quick release member is used to detachably mount a propeller (310) on a driving mechanism (320). The quick release member comprises a mounting portion (1) connected to or formed on either one of the propeller or the driving mechanism, and a locking mechanism (2) formed on or connected to the other one of the propeller or the driving mechanism. The locking mechanism comprises a main body portion (21) and a locking portion (22). The main body portion is connected to the driving mechanism. The main body portion has an accommodation space (211). The locking portion is at least partially located in the accommodation space. The mounting portion is accommodated in the accommodation space, and rotates relative to the locking portion in the accommodation space, such that switching between a locked position and an unlocked position is performed on the mounting portion and the locking portion, and correspondingly switching between a locked state and an unlocked state is performed on the propeller and the driving mechanism. The invention allows a user to implement detachable connection between the propeller and the driving mechanism by means of a single rotation operation, and is easy to operate.
