Publication number: 20220341215Abstract: A lock device includes a shell, a bolt mechanism, a magnetic member, and a magnetic sensing module. The magnetic member is movable with the bolt mechanism. When the bolt mechanism is moved between a locking position and an unlocking position, the magnetic sensing module senses a magnetic force variation of the magnetic member. The lock device further includes a magnetic force generation member disposed on a wall. When a door located at a door-closed position with the bolt mechanism being moved to the locking position is shaken relative to the wall, the magnetic sensing module senses a magnetic force variation of the magnetic force generation member.Type: ApplicationFiled: March 7, 2022Publication date: October 27, 2022Applicant: TAIWAN FU HSING INDUSTRIAL CO., LTD.Inventors: I-Chang Shih, Shih-Min Lu, Pi-Shun Chang
