Patent ID: 11377888

Abstract:
A remanence-eliminating magnetic lock includes a housing, an electromagnetic body and a resilient abutting member. The electromagnetic body can be assembled into the housing and receive externally-supplied electricity to generate a magnetic attraction force on a top surface thereof. The resilient abutting member has a fixing end to be fixed within the housing or the electromagnetic body, and an abutting end exposed from the housing or the top surface of the electromagnetic body. A peak of the abutting end is higher than the top surface of the electromagnetic body. When a metal member is magnetically attached to the top surface of the electromagnetic body, the metal member pressures the abutting end to deform. When the supply of electricity to the magnetic lock is cut off, the abutting end pushes the metal member through a restoring force thereof to move the metal member away from the electromagnetic body to eliminate remanence.
