Key inserts before the rotary locking cylinder 8, and two-layer pellet shot from a slingshot is interlaced up and down in the rotary locking cylinder 8, and rotary locking cylinder quilt 8 this moment two-layer pellet shot from a slingshot up and down blocks, and can not rotate in tapered end body 9, namely lock can not be opened.After original key inserted rotary locking cylinder 8, pellet shot from a slingshot was up moved by key thrust, and after whole key inserted lock core, two-layer pellet shot from a slingshot is neat up and down was arranged in rotary locking cylinder and tapered end body 9 junctions.At this moment, rotary locking cylinder 8 is no longer blocked by pellet shot from a slingshot, can freely rotate in tapered end body 9, and lock is opened.When inserting lock core with non-original key, pellet shot from a slingshot also can be moved upward by thrust, but the groove difference, the pellet shot from a slingshot displacement produces difference.Make that the little pellet shot from a slingshot displacement of original displacement is excessive, surpass the maximum value of its design, pellet shot from a slingshot produces pressure to switch, switch closure, and the outer warning device of lock body is connected with switch, so the closure of switch makes the warning device conducting, sends anti-theft alarm function.Warning device can be audio alert, can be dialing, also can be that screen is taken pictures.So long as abnormal operation causes switch closure, all can produce corresponding anti-theft alarm function.
When lockset is in closure state, the triangle indirect switching tip at rotary locking cylinder 8 back sides up, I11 has individual pressure to the elastic pressure contact switch, makes that two shell fragments are in contact with one another in the elastic pressure contact switch I11,3 among Fig. 5 ' and 4 ' connector lug are conducted.This moment, electric current flowed out from battery A is anodal, after electric current arrives protective resistance E, can be divided into both direction: flow to diode D and joint 2 '.But this moment, lock was locked, also namely lock lead I13 in the body with joint 1 ' and joint 2 ' be connected together, joint 2 ' do not have element to joint 1 ' branch road, so electric current can directly flow to joint 1 from joint 2, the negative pole that flow back into battery at last forms a closed circuit.On another direction, be forward voltage because diode D adds at this moment, electric current can conducting, but the element that connects thereafter is big resistance alarm chip, so electric current can not flow to the branch road at diode D place.Ultimate current flows back to battery A negative pole from the lead I13 in the lock body, owing to there is not the integrated voice guard chip of current direction B, therefore integrated voice guard chip B does not work, and this moment, lock was in anti-theft state.
When lock body 2 is destroyed; the lead I13 of the inside is disconnected; cause joint 2 ' with joint 1 ' no longer be connected; electric current can only flow to diode D after flowing through protective resistance E; what this moment, diode D added is forward voltage; electric current can flow to integrated voice guard chip B and joint 5, but joint 5 still is not connected with other lead.So electric current is got back to battery A negative pole after flowing through integrated audible alarm chip B, because integrated audible alarm chip B alives, loudspeaker C is reported to the police, this situation belongs to cuts the lock anti-theft alarm function.
When the car owner normally unblanked, because rotary locking cylinder 8 welds a triangle indirect switching 10 behind, it rotated with rotary locking cylinder 8.When rotary locking cylinder 8 rotations 60 degree were opened lock, triangle indirect switching 10 in the vertical directions can form a downward displacement difference, make closed elastic pressure contact switch I11 disconnect the electric current that has cut off entire circuit.At this moment, the lock body transfers to tapered end can't make alarm chip work and cause warning, can avoid the situation of false alarm to take place.
Above-mentioned three kinds of embodiment can be following three kinds of situations in actual conditions.
1, when stealer destroys the utility model anti-theft vehicle lock with cutting pliers, because the steel lock has certain rigidity, cutting off needs certain hour.After the lock body is cut off half, thin wire in the lock body also can be cut off, because lead has retractility can be drawn (avoided because of binding clip be metal conducting again) by two ends, lead short-circuit alarming chip functions disappears, alarm chip has electric current to send burglar alarm sound by operate as normal, the caution stealer is realized cutting lock and is stolen warning function.The chimes of doom of burst can play deterrent effect to the thief, makes the thief fall flurried and escapes, and the passerby around chimes of doom also can make tells, and the position stolen takes place, thereby stealer is completely exposed, and has realized anti-theft feature.
2, when stealer takes unlocking tool to steal, that can not stop behind the instrument insertion lock core is rotating, and in the process of attempting, can cause some pellet shot from a slingshot excessive to top offset, surpasses its maximum displacement when design.The pellet shot from a slingshot displacement is excessive, and the elastic pressure contact switch is subjected to the external force closure, thereby makes the alarm chip in the anti-theft warning circuit have electric current to pass through, and alarm will be worked and be sent the voice burglar alarm.This moment, the chimes of doom of burst played warning function to the thief, even the car owner is not at the scene, but because stealer is caused easily after warning that people on every side notes, thereby dare not proceed to steal, thereby realize the anti-poly-talented anti-theft feature of unblanking.
3, when stealer takes the picking lock mode to steal, if the position of sled lock body and tapered end joint then belong to and cut lock pilferage warning one class.State will be for after the metal sharp weapon will lock body and prize from tapered end inside, and lead and warning circuit disconnect, and are equivalent to lead and are cut off, and impel the alarm chip operate as normal and send warning; If the position lock core of sled then belongs to the anti-poly-talented antitheft class of unblanking.Stealer inserts metal sharp weapon purpose in the lock core and wishes that pellet shot from a slingshot is deformed by powerful extrusion force, disabler, and the twisting resistance that recycling is certain rotates lock core and then successfully unblanks.The metal sharp weapon can cause that the pellet shot from a slingshot displacement surpasses the threshold of its design after inserting lock core, and the elastic pressure contact switch is subjected to the external force closure, impels alarm electric current to be arranged by sending burglar alarm.
Although above the specific embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned embodiment according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that manual and accompanying drawing contain yet, all should be within protection domain of the present utility model.
