Title:
PROTECTION LOCK MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/129283
Kind Code:
A1
Abstract:
A protection lock mechanism (10), comprising a lock pin (102), a power pin (103), a first electro-magnetic induction element, (104) and a first elastic element (105). The power pin (103) engages with or separates from the lock pin (102); the first electro-magnetic induction element (104) is located on the power pin (103), and the first elastic element (105) is connected at the end of the lock pin (102); when the first electro-magnetic induction element (104) pulls in the external electro-magnetic device, an acting force is applied to the lock pin (102) along the retracting direction such that the lock pin (102) is in a retracted state; when the first electro-magnetic induction element separates from the external electro-magnetic device, the first elastic element (105) applies to the lock pin (102) a acting force along the projecting direction such that the lock pin (102) is in a projecting state. The lock pin (102) can switch between a projecting state and a retracted state electro-magnetically, thus having higher efficiency and reliability.
