The intelligent lock of the embodiment has an unlocking state and a locking state, the clutch mechanism has a connection state and a separation state, and the working principle of the intelligent lock of the embodiment is described below by combining the states.
When the intelligent lock is in a closed state, the clutch mechanism is in a separated state, the front handle assembly is rotated clockwise (namely the front handle assembly is pressed downwards), the first linkage piece 8 is driven by the front handle assembly, and the first linkage piece 8 cannot indirectly drive the first connecting piece 6 to move through the clutch assembly because the first linkage piece 8 is separated from the clutch mechanism, and the front handle assembly is in an idle state and cannot realize unlocking;
when the intelligent lock needs to be unlocked, the clutch mechanism acts and is switched to a connection state, specifically, one end, away from the front handle assembly, of the first linkage piece 8 is connected with the clutch mechanism, then the front handle assembly is rotated clockwise, the first linkage piece 8 is driven by the front handle assembly, and the clutch mechanism drives the first connection piece 6 to enable the lock tongue to retract, so that unlocking is achieved, namely the intelligent lock is switched from a closed state to an unlocked state;
when this intelligence lock is in the state of unblanking, clutching mechanism is in connected state, and first linkage 8 drives second linkage 9 anticlockwise rotation under the effect of handle subassembly in the front to drive first connecting piece 6 through clutching mechanism and make the spring bolt stretch out, realize closing the lock, this intelligence lock switches to the closed lock state by the state of unblanking promptly.
The intelligence lock of this embodiment locates between lock body 3 and the back handle subassembly with closing the mechanism, sets up in the door inboard promptly, and personnel's unable contact has avoided the violence to unblank, and the security level is high, and when this intelligence lock was in the closed lock state moreover, preceding handle subassembly was in idle running state, and the unable preceding handle subassembly of prying comes the violence to unblank, has further improved the security performance of this intelligence lock.
The intelligence lock of this embodiment except having good security performance, will closing the mechanism setting in the door inside back, preceding handle subassembly is small, accords with the ultra-thin design trend of present intelligence lock.
As shown in fig. 5, the first link 8 passes through a first space 10 provided on the first link 6 and can rotate in the first space 10. Specifically, the first space 10 is a through hole, the first linkage member 8 is in clearance fit with the through hole, and the first linkage member 8 is coaxially arranged with a central axis of the through hole.
When clutching mechanism is in connected state, rotate preceding handle subassembly, first linkage 8 receives preceding handle subassembly drive, first linkage 8 is at the through-hole internal rotation, drive first connecting piece 6 action through clutching mechanism then and realize unblanking, first linkage 8 does not have the influence to first connecting piece 6 at the in-process of unblanking, but very ingeniously drive first connecting piece 6 through clutching mechanism and realize unblanking, consequently, do not have the requirement to the structure of lock body 3, make the intelligence lock suitability of this embodiment better.
As an alternative embodiment of the first space 10, the first space 10 is a groove, through which the first linkage 8 passes and can rotate.
In the embodiment in which the first linkage member 8 is changeable, a second space through which the first linkage member 8 passes is provided in the lock body 3, that is, the lock body 3 needs to be modified in adaptability, and in order to adapt to most of the lock bodies 3 on the market, the first linkage member 8 may be connected to the clutch mechanism by bypassing the lock body 3.
Further, the linkage assembly further comprises a second linkage part 9, a limiting groove 13 is formed in the second linkage part, and one end, away from the front handle assembly, of the first linkage part 8 is connected with the clutch mechanism through the limiting groove 13.
