Document Type and Number:
WIPO Patent Application WO/2024/004443
Kind Code:
A1
Abstract:
A locking device (100) can transition between a locked state and an unlocked state. The locking device (100) comprises a lock pin (101), a solenoid (110), and a pressing unit (120). The lock pin (101) can be moved between a locked position (P11) where a propeller (20) is locked and an unlocked position (P12) where the propeller (20) is not locked. The pressing unit (120) presses the lock pin (101) to the locked position (P11) by a mechanical pressing force (F12). The solenoid (110) is formed of a solenoid coil (111) and a plunger (112). The plunger (112) moves the lock pin (101) to the unlocked position (P12) against the mechanical pressing force (F12) when an electric current is caused to flow to the solenoid coil (111).
