Lock with multiple switchable operating modes

A lock with multiple switchable operating modes, having a first operating mode and a second operating mode, and comprising:

• a front lock body;
• a rear lock body;
• a connecting rod, wherein one end of the connecting rod is connected to the rear lock body, and the other end of the connecting rod is fixedly connected to a driving member extending into the front lock body;
• an electric clutch mechanism arranged on the front lock body, wherein the electric clutch mechanism has a first clutch member that is capable of being engaged with or separated from the driving member;
• a mechanical lock cylinder arranged on the front lock body, wherein the mechanical lock cylinder has a second clutch member that is capable of being engaged with or separated from the driving member;
• an identification module arranged on the front lock body and electrically connected to the electric clutch mechanism;
• a first switch member arranged on the front lock body;
• a blocking member movably arranged on the front lock body;
• a first linkage mechanism, wherein the first linkage mechanism comprises an operating member arranged on the rear lock body, a moving member arranged on the front lock body, and a linkage member arranged between the operating member and the moving member, the moving member has a first operating position and a second operating position, the operating member is capable of driving the moving member to switch between the first operating position and the second operating position through the linkage member, the moving member located at the first operating position is capable of triggering the first switch member, so that the first switch member generates a trigger signal, and the moving member located at the second operating position is capable of driving the blocking member to move so as to prevent the first clutch member and the driving member from being engaged to enable the lock to be switched to the second operating mode;
• and
• a control module, wherein the control module is electrically connected to the identification module, the electric clutch mechanism and the first switch member, and is configured to control the lock to be switched to the first operating mode according to the trigger signal;
• wherein the front lock body is movably provided with a cover plate capable of closing a keyhole of the mechanical lock cylinder, the cover plate is coupled to the moving member through a second linkage mechanism, the lock further has a third operating mode, the moving member has a third operating position corresponding to the third operating mode;
• and wherein the linkage member is a rod member, the moving member is further provided with a second eccentric portion, the second eccentric portion and a first eccentric portion of the moving member are arranged at an interval along a length direction of the rod member;
• when the operating member drives the rod member and the moving member to rotate together to enable the moving member to be located at the third operating position, the first eccentric portion drives the blocking member to move to abut against a moving block of the electric clutch mechanism, so that the first clutch member is prevented from being engaged with the driving member, the second eccentric portion is capable of shifting one end of a lever of the second linkage mechanism, so that the other end of the lever drives a second pivot of the cover plate to rotate and the cover plate is kept closing the keyhole.
