If the lock needs to be unlocked through the standby unlocking structure, the standby key is inserted into the lock hole 1322, the lock cylinder is engaged with the shell through the clutch structure, and the rotating shaft can be driven to rotate after the standby key is rotated, so that the manual emergency unlocking function is realized.

Referring to fig. 14, this intelligence lock can be quick-open type's intelligence lock, and this intelligence lock includes panel 100, is provided with handle 110 on the panel, installs the lock logical fit clutch who shows above fig. 2 to fig. 13 in the panel 100, and the intelligence lock of this embodiment sets up the lock logical fit clutch, has better commonality, can not receive the restriction of original mechanical lock body specification and size and the trompil of the door body, has good commonality.

The application provides a door lock wildcard clutch, including casing 1303, casing 1303 is provided with first end 1301 and second end 1302 in the relative both sides, connects through drive mechanism between first end 1301 and the second end 1302. The first end 1301 may be a power input end and the second end 1302 may be a power output end, the first end 1301 being adapted for driving connection to a handle of a door lock and the second end 1302 being adapted for driving connection to a cylinder of the door lock. A clutch mechanism is arranged between the first end 1301 and the transmission mechanism, the clutch mechanism comprises a driving part connected with the first end and a driven part connected with the transmission mechanism, a clamping mechanism is arranged between the driving part and the driven part, and the clamping mechanism is used for separating or jointing the driving part and the transmission part 1316. When the transmission mechanism is driven by the door handle, the rotating shaft of the second end 1302 can be driven to rotate. Other structures of the door lock general clutch device can be referred to the description of fig. 2 to fig. 13, and are not described again here. The intelligent door lock provided by the embodiment can be used for connecting the door handle with the lock cylinder in a transmission manner, and can unlock the lock body when the handle is rotated, so that the operation is smoother and the performance is more reliable.

Having described embodiments of the present application, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
