A kind of electromagnetic clutch device for intelligent fingerprint door lock
This utility model relates to intelligent lock technical field, is specifically related to a kind of electromagnetic clutch for intelligent fingerprint door lock
Coded lock is the one of lock, and during unlatching is a series of numeral or symbol, and word coded lock can be divided into: machinery
Coded lock, digital cipher lock etc..The password of coded lock is the most all to arrange and non-real combination.Partial password lock only makes
With a rotating disk, the several video discs in lock or cam rotation；Also some coded lock be rotate one group several be carved with numeral dial
Wheel rim, directly drives the machinery within lock.The clutch that existing market uses motor as power to open coded lock is in the majority.
Chinese patent literature CN204166592U discloses a kind of dynamic puzzle-lock, by client and dynamic puzzle-lock group
Become.Dynamic puzzle-lock includes UDID and temporal operator, generates dynamic password by UDID and temporal operator, and client obtains dynamic
State password, realizes unlocking after dynamic password locks input dynamic password.Dynamic puzzle-lock includes keyboard transmission circuit, controls electricity
Road, motor-drive circuit, lock a door sensor and door condition sensor, this control circuit drives electricity with keyboard transmission circuit, motor
Road, door condition sensor, sensor of locking a door are connected.When smart mobile phone is as client, between mobile phone and dynamic puzzle-lock
Generate password by temporal operator (PKI) and UDID (private key), carry out with coded lock at the UDID of mobile phone terminal input coded lock
Pairing, the dynamic password that after pairing, i.e. available handsets generates opens coded lock, according to the change of temporal operator, cell-phone customer terminal and
Coded lock removes to generate the password of a figure place the most fixing with the regular hour.
The motor of market is as the power of promotion clutch now, but the less stable of motor and service life are relative
Shorter, if with electric magnet do driving force performance more stable while service life be greatly prolonged, therefore need badly a kind of for intelligence
The electromagnetic clutch device of fingerprint gate lock.

Detailed description of the invention
Detailed description below is used for illustrating this utility model, but is not limited to scope of the present utility model.
As it is shown in figure 1, this utility model provide a kind of electromagnetic clutch device for intelligent fingerprint door lock, described electromagnetism from
Locking device includes main panel 1, door handle 2, clutch shell 4 and clutch inner bag 5, and described main panel 1 is provided with opening 3, described
Door handle 2 blocks mutually from the front of main panel 1 through one end of described opening 3 with the clutch shell 4 being positioned at described main panel 1 reverse side
Connecing, the other end of described clutch shell 4 is formed as cylinder, and the barrel of this cylinder is provided with groove 8；Described clutch inner bag 5 sets
It is equipped with through hole 9 and is positioned at the steel core 7 in described through hole 9, the aperture phase of the side of described groove 8 and described through hole 9
Right, opposite side is provided with solenoid 6, and one end of described steel core 7 is provided with spring 10；When described solenoid 6 power-off, institute
Stating spring 10 makes described steel core 7 be positioned in described through hole 9, and when described solenoid 6 is energized, described solenoid 6 adsorbs
Described steel core 7 enters in described groove 8, makes described clutch shell 4 and clutch inner bag 5 phase clamping；It is provided with on described main panel 1
Fingerprint reader, described fingerprint reader is for by identifying that fingerprint controls the energising of solenoid 6, the master of finger-print puzzle lock
People can be previously set fingerprint, and the brush finger stricture of vagina that the most every time needs to enter can make solenoid 6 be energized, and conduction time is permissible
Be set as the 3-5 second, during this period in, owner can turn the handle enablings, if having crossed this period, solenoid 6 power-off, clutch
Shell 4 and clutch inner bag 5 disconnect clamping, then cannot open the door.
A kind of detailed description of the invention, as it is shown in figure 1, described electromagnetic clutch device is provided with the side controlling door lock skew bolt position
Bar 11, described square bar 11 is fixing with described clutch inner bag 5 to be connected.When clutch inner bag 5 rotates, square bar rotates and promotes door lock inclined
Tongue passes in and out from glossal canal, thus controls the switch of door.
A kind of detailed description of the invention, is provided with to the battery of solenoid in described electromagnetic clutch device, electromagnetism from
Locking device can also be electrically connected with external power source.
A kind of detailed description of the invention, as it is shown in figure 1, described steel core 7 includes integrated coaxial thick core and thin core, institute
Stating spring 10 to be enclosed within outside described thin core, and cannot be enclosed within the outside of thick core, when making solenoid power-off, steel core 7 is pushed away by spring
From groove 8.
A kind of detailed description of the invention, as it is shown in figure 1, described solenoid 6 is provided with permanent magnetism iron core 12, so that electromagnetism
