The general protective unit of row management, maintenance, operation reduces security risk to ensure personal safety and equipment safety.Of the invention
Electric lockset 100 can be realized the reliable detection of 100 state of electric lockset, improve the security performance of electric lockset 100, moreover,
Detection accuracy can also be improved, guarantees the reliability that electric lockset 100 uses.
Referring to Fig. 1 to Fig. 4, in one embodiment, electric lockset 100 includes lock housing 110, lock core component 120, control piece
(not shown) and detection components 130.Lock housing 110 plays protective action, and the components of electric lockset 100 are all set in lock housing 110,
While avoiding dust, sundries etc. from entering, it can also be ensured that the safety of electric lockset 100 avoids damage to lock core component 120
Electric lockset 100 is caused to be pried open.Electric lockset 100 is used cooperatively with computer key, realizes the locking and solution of electric lockset 100
Lock.
Lock core component 120 is rotatably set in lock housing 110, and has latched position and unlocked position, lock core component 120
Including shaft 121.Lock core component 120 is the main locking structure of electric lockset 100.After computer key protrudes into lock housing 110, with lock
Core assembly 120 connect, rotation computer key can synchronous drive lock core component 120 rotate, realize lock core component 120 locking and solution
Lock.When computer key band movable lock core component 120 unlocks, lock core component 120 is in the unlocked position；Computer key band movable lock core component
When 120 locking, lock core component 120 is in the locked position.
Control piece and computer key communicate to connect.120 state in which of lock core component can be transferred to computer by control piece
Key, computer key judge that completing authorization unlocking operates according to the state of lock core component 120.Optionally, control piece is control electricity
Road plate.Moreover, control piece can also receive the power supply of computer key.Detection components 130 are used to detect the rotation shape of lock core component 120

132, inductance element 131 is electrically connected with control piece, and is set to shaft 121, and detection piece 132 is set to lock housing 110.Lock core component
120 have unlocked position and latched position, wherein a position, and inductance element 131 and detection piece 132 are with contactless inductive side
Formula is oppositely arranged, and in another location, inductance element 131 is far from detection piece 132.Lock core component 120 is in unlocked position and locking bit
Switch between setting, control piece can detecte and the impedance variations of feedback inductance element 131.Specifically, control piece is by inductance element
131 impedance variations feedback to the computer key.
Control piece is electrically connected with inductance element 131, computer key be inserted into lock core component 120 after, can by control piece to
Inductance element 131 is powered, so that inductance element 131 generates electromagnetic field.Moreover, computer key band movable lock core component 120 is unlocking
During position and latched position switching, the impedance of inductance element 131 can change, and control piece is sentenced according to the impedance variations
Whether the state of disconnected lock core component 120 changes.
It should be understood that the phase when the position of lock core component 120 does not switch, between inductance element 131 and detection piece 132
It will not change to position, 131 impedance of inductance element that control piece cannot detect changes.When lock core component 120 exists
When switching between latched position and unlocked position, the relative positional relationship between inductance element 131 and detection piece 132 can become
Change, control piece can detect that the impedance of inductance part 132 changes.

From lock housing 110, and it is fully located in shaft 121.In this way, computer key can drive shaft 121 to rotate relative to lock housing 110,
Realize the unlock of lock core component 120.
After computer key band movable lock core component 120 moves to latched position from unlocked position, after extracting computer key, spiral shell
Spool 122 powers off, meanwhile, the iron core of solenoid 122 stretches out, and the iron core of solenoid 122 can squeeze spacer pin 123, so that limit
Pin 123 removes shaft 121.At this point, 123 part of spacer pin, which is located at 110 part of lock housing, is located at shaft 121, lock core component 120 is realized
Locking.
When electric lockset 100 locks, the iron core of solenoid 122, which powers off, to be stretched out, and limitation spacer pin 123 acts.It limits at this time
Pin 123 is located at lock housing 110 and shaft 121, limits the relative rotation of lock housing 110 and shaft 121, the lock of 131 end of inductance element
110 material of shell is metal.When computer key is inserted into lock core component 120, the electrode of computer key and the electrode of lock core component 120
Contact is powered to control piece, and carries out identification and authorization.After authorizing successfully, control piece is powered to solenoid 122, helical
The iron core of pipe 122 retracts, and spacer pin 123 is allowed to act, and spacer pin 123 is located inside shaft 121 at this time, can be rotated computer key
Carry out unlocking operation.When computer key band movable lock core component 120 turns to unlocked position, the end face of inductance element 131
Detection piece 132, detection piece 132 are nonmetallic materials, and the impedance of inductance element 131 changes, and control piece determines lock core component
120 in the unlocked state and feedback informations determine to complete to award to computer key, computer key according to 100 status information of electric lockset
Unlocking work is weighed, and working condition is back to host.
Electric lockset 100 of the invention passes through the contactless inductive realization lock core component of inductance element 131 and detection piece 132
The cooperation of 120 state-detection, inductance element 131 and detection piece 132 can guarantee detection accuracy, and then guarantee electric lockset
The accuracy of 100 state-detections avoids the problem that misjudgement and erroneous judgement occurs.Meanwhile inductance element 131 is processed, service life, operation
Etc. extraneous factors influence it is smaller, it is ensured that electric lockset 100 work reliability, improve electric lockset 100 service performance.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the record scope of this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
