The quick release part (300) comprises a limit hole (301) arranged on the outer rotating sleeve (153), the handle connecting axle (270) and fixed mounting cap (202) respectively. In each case, a spring (302) is arranged in the limit hole (301), and a projecting block (303) is connected on the spring (302), the outer handle (110), inner handle (201), inner housing (212) and outer housing (211) are provided with mounting holes (304) corresponding to the projecting block (303) position. Depression of the projecting block (303) accessed via the quick release part (300) allows the outer handle (110), inner handle (201) and/or fixed mounting cap (202) to be decoupled and rotated independently from the handle connecting axle (270), the outer rotating sleeve (153), and outer housing (211) respectively.

The working principle of the intelligent cylinder lock is as follows. When opening the door with a key outside: the key is inserted into the key pin tumbler (151) to turn for driving the lock rod (152), and the lock rod (152) pushes the top pin (164) into the through hole (166), then the door lock can be unlocked by turning the handle (110) or key in the same direction. The rotating key allows the top pin (164) to spring back through action of the the top pin spring (165), so that the outer handle (110) is in idle state.

When opening the door and the motor (246) is started. The communication device or smart panel (111) gives a control chip signal to drive the motor (246) to rotate, the profiled wheel (244) on the motor (246) rotates to move the connecting axle (270), pushing the push housing (251) above the connecting axle (270) forward. With the moving of the push housing (251), the driving mechanism in the push housing (251) moves forward as well, the pins (255) will be pushed into the sockets of the ratchet wheel (258) face, and the outer handle (110) will be rotated. The outer rotating sleeve (153) will drive the rotation of the connecting shaft (131), and the ratchet wheel (258) connected on the connecting shaft (131) will also rotate, thus driving the rotation of the transmission means (250), and the inner rotating sleeve on the transmission means (250) will drive the rotation of the lock cylinder cam wheel (140) on the inner rotating sleeve (154) to realize the unlocking.

After the motor signal ceases, the transmission means (250) is reset by the reset spring (274) of the front end. Because the transmission means (250) is reset to the original position, the rear pin leaves the jack of the ratchet, so that the external handle rotation can not be linked to the transmission means (250). In this way, the outer handle (110) is idling and the outer handle (110) can not be unlocked. If the inner handle (201) turns in one direction (clockwise in the example shown in figure 8), because of the co-operation of ratchet of the profiled wheel (244) and pins (255) on both sides, the pins will slip on the slope of the ratchet, and the lock will not unlock. If handle is turned in the opposite direction, the pins will drive the ratchet to rotate, thus interconnecting the transmission means (250) to achieve unlocking of the lock.

The above is only a preferred embodiment of the intelligent cylinder lock, and is not used to limit the intelligent cylinder lock, the intelligent cylinder lock can have various changes for the technician in this field. Any made modification, equated substitution or improvement within the spirit and principle of the intelligent cylinder lock shall be included in the protective range of the intelligent cylinder lock.

In this specification an apparatus/method/product "comprising" certain features is intended to be interpreted as meaning that it includes those features, but that it does not exclude the presence of other features.

Many variations are possible without departing from the scope of the present invention as defined in the appended claims.
