Lock rotating body component 5；In the present embodiment, it is provided with antenna 8 and antifreeze plate 9 in certification identification window, antenna 8 is used for signal and passes
Pass, antifreeze plate 9 is used for the impact to signal of isolating metal lid and housing, additionally, intelligent lock protector core 4 also includes trigger switch
22nd, motor 20, shift fork 21, lockout post 16, lockout post spring 17, disposition of latch arm 18, locking arm axle 19；
For triggering locking rotating body component 5, as shown in Figure 7,8, it include fore shell 11,12, two groups of protection posts 13 of back cover,
Two groups of triggering pins 14 and the triggering pin spring 15 connecting triggering pin；It is provided with recess channels in described fore shell 11, described triggering pin
14 are arranged in recess channels with triggering pin spring 15；
The lower section of triggering pin is provided with lockout post 16 and connected lockout post spring 17, by described lockout post 16
It is additionally provided with trigger switch 22, locking arm axle 19 and the disposition of latch arm 18 that can rotate around locking arm axle 19, in described disposition of latch arm 18
The shift fork 21 that lower section is provided with motor 20 and connects machine shaft；
Control circuit, Intelligent key set and above-mentioned intelligence shield lock are included based on the shield lock system that above-mentioned intelligent lock protector is realized
Device, described control circuit includes control circuit box and device control board in the inner and battery；Described control circuit box leads to
Cross wire to be connected with the motor in intelligent lock protector core, trigger switch and antenna；Described Intelligent key set includes elastic key set
Put intelligent chip for identification with being installed on elastic key, described elastic key set can be placed on the handle position of key
Put, and hypertonic is stretched according to handle shape, be allowed to be fitted close with key handle.
The operation principle of this intelligent lock protector is：
Before being not inserted into key, it is installed on the protection post 13 in the triggering blocks rotation body assembly 5 in intelligent lock protector core 4
It is pushed together closing key insert port 10 under triggering pin 14 and triggering pin spring 15 effect, protection post 13 also has in closing
There are rainwater-proof, dust, the function of anti-foreign body；Lockout post 16 insertion triggering rotation under lockout post spring 17 effect in intelligent lock protector
The in the hole turning triggering pin 14 in atretic body assembly 5 withstands triggering pin 14, and disposition of latch arm 18 is kept off under the bossing of lockout post 16,
Withstand lockout post 16, disposition of latch arm 18 is withstood by the convex shape in the front and rear covers of intelligent lock protector core, the shift fork 21 on motor 20
It is in locked position of coupler, trigger switch 22 is contacted with the projection of lockout post 16.
When being ready for insertion into legal key, revealed near the signal of lock protector shell 1 using the Intelligent key set on the shank of the key
Seam 3, transmits signal by antenna 8 in lock protector shell 1 for the protection, the authentication letter in the intelligent chip that Intelligent key puts
Breath is transmitted to control board, and after control board is passed through to authentication information certification, controlled motor 20 executes unblock
Action, motor 20 drives shift fork 21 to go to released state, and shift fork 21 is synchronous simultaneously drives disposition of latch arm 18 to rotate around locking arm axle 19
Leave the raised position of lockout post 16.
At this moment insert legal key, protection post 13 key effect under move, head on simultaneously lockout post 16 move away tactile
Tuorbillion turns the hole of the triggering pin 14 of atretic body assembly 5, so that lockout post 16 leaves recess channels, at this moment rotatable key solution
Lock, now the projection of trigger switch 22 and lockout post 16 is in separating contacting state.
When extracting key after unblock, lockout post 16 is upspring under lockout post spring 17 effect and is entered triggering blocks rotation body group
The in the hole of the triggering pin 14 of part 5, trigger switch 22 triggers, and control circuit controls controlled motor action, and shift fork drives disposition of latch arm fortune
Move and withstand lockout post raised position.
When illegal key or instrument insert, because not over legal identification, motor 20 is not carried out unlocking
Action, disposition of latch arm 18 withstands lockout post 16, and lockout post 16 withstands triggering pin 14 and protection post 13, leads to key or instrument cannot insert
Enter, further, since using illegal key or instrument when attempting to open protection post 13 and enter key insert port 10, can push up
Lockout post 16 to move down a little apart from so that trigger switch 22 and lockout post 16 disengage and trigger warning, warning can
Locally to carry out buzzer warning, in alarm signal can also being transferred to user mobile phone or be reported to the police by mixed-media network modules mixed-media
The heart；
If by force by force after tamper protection post 13, illegal key or instrument is allowed to insert, but the lockout post of high intensity
The in the hole of the 16 triggering pins 14 being inserted in triggering blocks rotation body assembly 5, makes triggering blocks rotation body assembly 5 block, illegal key
Or instrument cannot rotate, if violence makes the safety groove rupture of high intensity lockout post 16 and triggering blocks rotation body assembly 5 again, break
The clogged with fragments split, between rotation head protector 2 and the keyhole of lock core, leads to instrument and illegal key to be difficult to continue into lock
Core, and using technical tool, lock core cannot be opened, thus can realize the high intensity guarantee to lockset.
Furthermore, it is necessary to explanation is：For the intelligent lock protector in this utility model, in its certification identification window
Identification module can also be set, and identification module includes but are not limited to fingerprint identification module, bluetooth module, NFC mould
Block, smart card identity module.Based on the program, the lock protecting utensil in this utility model is for fingerprint recognition authentication function, NFC mobile phone
Identification authentication function, smartcard identification authentication function, Bluetooth communication authentication function, thus realize fingerprint unlocking, unlocked by mobile telephone, brush
Card unlocking etc., more intelligent.
In the above-described embodiments, triggering locking rotating body component 5 employs two groups of protection posts and triggering pin so that just adopting
During reverse side key, anti-plug and anti-rotating function can play a role, it is possible to use 1 group of protection post and triggering pin, be allowed to apply
In one side key, in addition it is also possible to be sold using more than 2 groups of protection post and triggering, thus corresponding to triangle, four directions, abnormity etc.
Other shapes of key.
Thus, scheme of the present utility model also have a lot of equivalent modes, the foregoing is only of the present utility model relatively
Good embodiment, not in order to limit this utility model, all made within spirit of the present utility model and principle any
Modification, equivalent and improvement etc., all within protection domain of the present utility model.
