Description

A kind of main machine for car theft-proof device

The present invention relates to a kind of main machine for car theft-proof device, it is suitable for variously using with the gasoline-powered vehicle.

Current automobile burglar problem has been listed in 21 century third place in the world hang-up, professional quarters understand, why the car alarm of our times various countries is not resolved on theft-proof question of substance, is because fail that password is become and start unique channel of vehicle.Be that car is stolen and not had cipher key or remote controller still can adopt to join car key steathily, use master key, short circuit ... etc. means vehicle launch is stolen it, be the omnipotent trump unique skill that they steal car and adopt short circuit to start.Can therefore password become to start unique channel of vehicle be car alarm design key of success, also only in this way could really bring into play the effect of password, otherwise the setting of password is exactly useless, and password is become start unique channel of vehicle, key does not lie in cipher key or remote controller itself, and is on the main machine for car theft-proof device.

As everyone knows, current commercially available car alarm, all be to be theft-proof main means with the passive warning of passiveness, then only be in automobile ignition control circuit, to have set up a electromagnetic switch on theft-proof question of substance by the control of cipher remote control device, though used cryptographic technique, but expert personage knows, in the cipher control system, though the preceding transmission of decoding is code signal.But the just voltage signal that transmit the decoding back promptly removes to drive electromagnetic switch with a vdc after the decoding, and these controlled parts also just drive with vdc simultaneously.Because in the open-type cipher control system, the controlled part on all transmission lines and the transmission line is all exposed, steals car with the short circuit startup therefore for the car illegal mining and caused opportunity.They can walk around the link that password transmits, come straight to the point, directly after decoding, do not need password, and the controlled part that only needs vdc just can drive is set about, omnipotent unique skill by short circuit, the control end of controlled part is received on the direct supply, it is put into operation, start the purpose that vehicle is stolen car thereby reach.As for saying the gps satellite locating and tracking system, it can not solve theft-proof substantive issue, only can after vehicle is stolen, follow the trail of, and on antitheft this meaning, be belated action, and costly, exhaust the people and drain the treasury.

I propose in the ZL92201912.6 that was authorized in 93 years, with a firm housing decoder, controller and high-tension coil or transistor ignitor or electromagnetic valve are shut inside scheme, this technical scheme, start to steal with short circuit and play positive role aspect the unique skill of car beyond doubt tackling the car illegal mining, yet above-mentioned electromagnetic valve is not the former startup of the vehicle requisite parts that turn round, therefore car is stolen and can very fast it be removed, and with a bit of pipe the oil circuit lashup can be stolen car then; As for saying high-tension coil, though be to start the requisite parts of running in the vehicle, but owing to do not have plug special, socket on the high-tension coil, two normal screws joints that only promising number is few, if so two joints anyone when buying a high-tension coil in addition and going to replace, also be not difficult at short notice the ins and outs of two lines to be made clear, and its reliable back startup vehicle that connects is stolen it.Firm housing adopts the disposable scheme of shutting described in the ZL92201912.6 in addition, in case the high-tension coil of rapid wear damages or by described decoder, the anti-theft controller that controller is formed damages, then must a complete set ofly change, waste very big, and this automobile component is by the disposable main machine for car theft-proof device of shutting of housing, though there is automobile component the inside--high-tension coil, but can not be compatible mutually with this kind vehicular spare parts, automobile parts shop also can't buy this and the incorporate high-tension coil of anti-theft controller, especially the oneself who can't resolve under the emergency condition saves problem, for example at the traffic lights crossing, anti-theft controller in the Car Burglar Alarm main frame, or high-tension coil breaks down suddenly and when casting anchor, then have to draw with trailer, or repurchase one the cover Car Burglar Alarm, or buy a high-tension coil etc., yet the uncertain meeting of driver change, cause delay very much.Because it is the unique skill that car robbers steal car that short circuit starts robber's car; therefore under any circumstance they can not abandon using this " magic weapon "; yet the pig-tail wire of the anti-theft controller of being made up of decoder, controller among the ZL92201912.6 does not have the short circuit safety method; in case car is stolen they short circuits; though vehicle can't start robber's car by short circuit after having adorned this Car Burglar Alarm of ZL92201912.6; yet but anti-theft controller has been ruined in the short circuit; car owner oneself will also can't start with car, wouldn't this be car owner's a grief?

The object of the present invention is to provide a kind of housing that passes through; with anti-theft controller; the former startup of cipher electric lock and automobile turn round requisite electric-controlled parts and plug special thereof; integrated constitute totally-enclosed of socket three parts; openable main machine for car theft-proof device; this main frame has fault and detects automatically; the outer pig-tail wire short circuit defencive function of Presentation Function and perfect anti-theft controller and adopt the oneself of secondary redundancy scheme to save function; and after described housing is opened by corresponding password; can repair or replace still keeping relatively independent separately described three parts in the described housing; make existing electronic cipher controller (be commonly called as cipher key; the cipher remote control device ... Deng) with the supporting use of this main frame after; this password can really become the unique channel that starts vehicle; that is the car illegal mining all can not steal vehicle startup with any way, and these ways comprise: 1; join car key steathily.2, use master key.3, short circuit starts (this is an omnipotent unique skill of stealing car).4, remove Car Burglar Alarm.5, change means such as vehicular spare parts and comprise up to now being found all steal the means of car to start vehicle, also comprise prevent trouble before it happens by starting the means of vehicle robber car.

The objective of the invention is to reach as follows:

Constitute this kind main machine for car theft-proof device, it is characterized in that being locked in the described housing is not to be high-tension coil, but engine controlling computer, or Spark Control Computer, or electronic controller, or the former startup of automobile such as igniting module etc. turn round requisite electric-controlled parts and plug special and socket, also include code signal acceptor circuit, antitheft relay, pig-tail wire short circuit protective circuit and the fault that are locked in the described housing detect read out instrument automatically;

Described decoder is the decoder and the commutation circuit thereof of the using and the reserved secondary redundancy structure;

Described firm housing is a cast steel manufacturing and the housing handled through vacuum quenching or desalination;

Described built-in lock is a blind cipher electric lock that is loaded in the described cast steel housing, it include the decoder of described password acceptor circuit shared when turning round requisite electric-controlled parts work, secondary redundancy structure and commutation circuit, actuator, antitheft relay and described function conversion controling switch, electromagnet, sliding mechanical locking bolt with the former startup of Control of Automobile or and described function conversion controling switch, DC machine, orienting sleeve, the directly sliding rod of non-rotary body, sliding mechanical locking bolt;

Described password acceptor circuit receives remote signal or the direct cable pin signal that receives from coding key or electromechanical password car key that transmits from corresponding remote controller, and behind the decoder of described secondary redundancy, actuator, antitheft relay, go to control the turn round start and stop of requisite electric-controlled parts of the former startup of described automobile, or with the keying of the described cipher electric lock of the common control of described function conversion controling switch;

Described fault detects read out instrument automatically, be in series by short circuit protection diode, light-emitting diode or together with current-limiting resistance, and the protection diode is locked in the described housing, and described light-emitting diode can cause outside the described housing, described fault detects the connection of read out instrument automatically, must synchronous working with the former startup of the described automobile requisite electric-controlled parts that turns round, and same pair of contact of shared described antitheft relay;

Combining between described cast steel housing and its lid is L type and inverted T shape lock pawl interlaced the forming after translation that cooperatively interacts on the edge separately by the two.

This kind main machine for car theft-proof device has following outstanding advantage:

Because this main frame is that a kind of three parts are integrated, the new parts of full-closed structure, thereby having constituted a kind of fully enclosed cipher control receiving system (promptly begins until controlled part from decoder, and the system that all blocked of the transmission line between them) by a housing, therefore make the former startup of the automobile requisite electric-controlled parts self that turns round just possess password, have very superior theftproof performance.Again because interior each parts of shell still keep its relative separately independence, and wherein Ang Gui vehicle launch just is to use original these parts that use on the automobile with the requisite electric-controlled parts of running, therefore can reduce the productive costs of Car Burglar Alarm main frame to greatest extent, the housing of more valuable is these new parts can be opened by crypto control unit, so just can be at any time to each parts in the integrated new parts of these three parts---former automobile electrically-controlled parts or anti-theft controller or cipher electric lock etc. are checked, keep in repair, maintained or change.Therefore, have fabulous compatibility between new parts and the existing automobile electrically-controlled parts, extremely desirable maintainability is arranged again.Below just in conjunction with goal of the invention, analyze the superior theftproof performance of the integrated new parts of three parts in detail;

Because new parts are a kind of fully enclosed cipher control receiving systems, therefore comprise decoder, actuator, antitheft relay, the former startup of automobile and turn round requisite electric-controlled parts and plug special thereof, transmission line between socket and above-mentioned each parts all is locked in the housing, car is stolen can't walk around the password transmission link again and directly outside with housing in circuit after the decoding carry out short circuit, and can only the former startup of automobile in the housing requisite electric-controlled parts that turns round be put into operation by corresponding password, vehicle could start, again owing to housing is handled through vacuum quenching or desalination, have anti-drilling, anti-saw, therefore the performance of pick-proof does not have corresponding crypto control unit housing just not imagine to open.This main machine for car theft-proof device, not only contained the omnipotent trump unique skill that current car robber uses short circuit to start, also rack one's brains to no avail even the Car Burglar Alarm main frame dismantled, because removed the Car Burglar Alarm main frame, the former startup of automobile in the housing requisite electric-controlled parts that turns round also will be dismantled simultaneously, and it is conspicuous that vehicle can't start.Even car steal agree to outbid to buy the former startup of automobile that is locked in the housing requisite accessory that turns round, also can be because of reasons such as the pattern of the model of its this accessory of various vehicles, specification, plug special, different sizes, and make car steal randomness steal garage and directly thoroughly contained, and randomness steal car account for car steal steal more than 95% of car probability.Still more regrettably at our this Car Burglar Alarm main frame, even car steal to come with preparation also can only be free-hand and return, reason is to be locked in the former startup of automobile in the housing requisite electric-controlled parts that turns round, himself and private jack have been integrated indivisible structure, and supporting with it plug special, also be locked in the housing, this plug special is that vehicle is joined when dispatching from the factory, can't buy at automotive parts store, even bought requisite this accessory of the former startup running of this automobile so car is stolen at automotive parts store, also can owing to its supporting plug special be locked in the housing so can't directly change.The pin that this plug has nearly number picks up (pin as some engine controlling computer can reach 81 more than) more than the bar, in other words, plug special is locked in the result in the housing, also will have number to pick up bar with this plug special bonded assembly lead leads to outside the shell in housing, if someone has a fantastic idea, attempt is with after a lot lead outside plug special causes shell is all cut off outside shell by the waist in the housing, a rule is checked the former startup of automobile that access buys from automotive parts store and is turned round the pin of private jack of requisite accessory again, and that can only be Arabian Nights.Not hard to imagine, so how tortuous lead among alarmed through each corner of vehicle, a rule make clear and guarantee to connect errorless easier said than done again? Still more, so multi-threadly to just all must reliably be connected more non-easy thing with every line of pin of falling in the accessory private jack.Especially it is pressed for time, be impracticable at all under the high-strung situation of mood.

Above-mentioned Car Burglar Alarm main frame if can be mixed crypto control units such as coding key described in ZL92201912.6 or the 93100750.X or electromechanical password car key, then with further strengthened.Because in the shank of the key, its confidentiality is self-evident with the password disposal solidifying for above-mentioned coding key or electromechanical password car key.This key comprises that the producer that produces it all can't join steathily.Therefore password really becomes the unique channel that starts vehicle and will become a reality.

The not only general-duty short circuit of this main machine for car theft-proof device starts unique skill it is had no way out, and the anti-theft controller of drawing in the shell mutual short circuit that respectively goes between all can be guaranteed can not damage anti-theft controller, car will not occur steals behind these pig-tail wire short circuits, car does not on the contrary go adrift, yet but anti-theft controller has been ruined car owner oneself difficult situation that car does not start yet of looking on the bright side of things during short circuit.For further improving the reliability of Car Burglar Alarm main frame, the weakest decoder has adopted the technical scheme of secondary redundancy in the anti-theft controller, as long as wherein a cover decoder has fault and can not decode, then the still available crypto control unit of car owner puts another set of standby decoder into operation, and is extremely desirable and reasonably solved self-rescue problem.In addition Car Burglar Alarm design-calculated fault detects read out instrument automatically, will verily show the working condition of Car Burglar Alarm, as long as LED lights, then vehicle launch not reason be that the anti-theft controller fault is done absolutely not just.For fault judgement and maintenance provide convenience.

The main machine for car theft-proof device of this structure, the vehicle that not only is fit to dispatch from the factory is installed, and also is fit to car manufacturer simultaneously and just it is installed before vehicle dispatches from the factory, and its theftproof performance, compatibility and maintainability are that current all car alarms are too far behind to catch up.

It is as follows now to be described with reference to the accompanying drawings the embodiment of the invention:

Embodiment 1: shown in Fig. 1 a in the main machine for car theft-proof device housing 1, the position 3 of reed shape is to place Spark Control Computer 4 recklessly, the profile of Spark Control Computer 4 is asked for an interview Fig. 1 b, only need K1-K3 three borehole jacks in the Hu reed shape position 3 of housing 1 are advanced in three screws that welded on the vehicle front-wheel fender guard during installation, and then K1-K3 three holes in the Spark Control Computer 4 shown in Fig. 1 b are also packed in above-mentioned three screws, and tighten up in shell with nut and to get final product.From said structure as seen, in case cover 2 lock after, whole housing and wherein mounted component just do not imagine to remove from car, yet the preceding topic of uncapping is to possess cooresponding crypto control unit.This housing is anti-drilling, anti-saw, pick-proof after vacuum quenching or desalination processing.Fig. 1 C 5 shown in for detect the described anti-theft controller that read out instrument etc. is formed automatically by the decoder of wireless infrared ultrasonic or wired acceptor circuit, secondary redundancy structure and commutation circuit thereof, actuator, antitheft relay, outer lead short circuit protective circuit, fault.The acceptor circuit of described anti-theft controller receives from corresponding remote controller or directly receives the code signal of sending here from coding key or electromechanical password car key, and the previously selected decoder of select switch that is sent in the described secondary redundant decoder commutation circuit is deciphered again through actuator, remove to control the former startup of the described automobile requisite electric-controlled parts that turns round behind antitheft relay and the contact thereof, or behind the function conversion controling switch, remove to control electromagnet in the described cipher electric lock, described electromagnet be subjected to the actuator of described anti-theft controller and the function conversion controling switch of drawing with the non-end that directly links to each other of described electromagnet " with " logic control.6 is sliding mechanical locking bolts among Fig. 1 a, when lid 2 when (Q direction) is mobile forward along direction shown in the arrow again after (directions X) covers on the shell 1 vertically downward, each L shaped lock pawl 7a on the lid 2 and inverted T shape lock pawl 8a will block mutually with L type lock pawl 7b and the inverted T shape lock pawl 8b on the housing 1, this moment is when (Y direction) stirs the toggle (not drawing among the figure) that is connected on the sliding mechanical locking bolt to the right with hand, sliding mechanical locking bolt 6 moves the right side (Y direction), and insert among the hole 8C that covers inverted T shape lock pawl 8a on 2, after the mechanical latch right side (Y direction) moves on to the position, the armature 10 of antitheft electromagnet 9 is pushed out under the effect of self spring (promptly pushes side, back (H direction) to, see also the directional pattern on Fig. 1 a), be stuck in the left end (Z end) of sliding mechanical locking bolt 6, block the sliding mechanical locking bolt, it can not be moved on a left side (Z direction), at this moment cover 2 and promptly can not move back (H direction), (SH) direction that can not make progress is again opened and has been lockable.When no corresponding password is imported described acceptor circuit, or during described function conversion controling switch access failure, the armature 10 of antitheft electromagnet 9 will can not be sucked into (promptly Q direction) forward and move, still blocking the sliding mechanical locking bolt makes it and can not move on a left side (Z direction), lid 2 will not opened, when obviously this housing is not opened, not only housing 1 and all parts wherein all can not remove from car, anyone also can not connect the switch J1 in the shell by the omnipotent unique skill of short circuit outside shell and (ask for an interview Fig. 1 C simultaneously, 1 expression main machine for car theft-proof device housing among Fig. 1 C, it all blocks following all parts within it: the 4th, and Spark Control Computer, 11,12,13,15, the 16th, with the private jack of described Spark Control Computer 4 one, 11 ', 12 ', 13 ', 15 ', 16 ' be and the supporting plug special of described private jack, the 14th, with the special-purpose vacuum tube base of described Spark Control Computer 4 one, 14 ' be the special-purpose vacuum tube joint supporting with described vacuum tube base, what place in 5 is anti-theft controller, available its antitheft relay contact J1 goes the power supply of control ignition controlling computer 4 to supply with in shell 1, or string connects in the line of high-tension coil outside the shell 1 in Spark Control Computer 4 ... Deng) unique J1 is connected, have only by from housing outside, importing this road of cooresponding password.

Be not difficult to find out from above analysis, this main machine for car theft-proof device is impossible adopt the way of short circuit to start, yet the tree may crave calm,but the wind will not drop, once the unique skill of once utilizing short circuit to start steal car and mad for a long time car steal be can be not readily, even clearly tell them, it is impracticable at all that our main machine for car theft-proof device starts by short circuit, they can not give up yet, short circuit must be a ten minutes blindness and random in this case, though so blindly the short circuit vehicle does not start certainly, yet is easy to anti-theft controller is damaged.If do not take effective measures, in case car steal steal in the car at short circuit anti-theft controller ruined, that will cause the deuce to pay, car owner oneself also can't start and used at least.Therefore considered extremely perfect outer pig-tail wire short circuit protective circuit in the design of this anti-theft controller; its outer pig-tail wire can guarantee that all anti-theft controller is safe and sound when combination in any short circuit in twos; simultaneously these outer pig-tail wires are when combination in any short circuit in twos; all can not make antitheft relay J adhesive, its contact J1 also can not connect.Principle is asked for an interview Fig. 1 d and Fig. 1 e, the firm housing of black surround 1 expression among Fig. 1 d and Fig. 1 e, and the circuit in the frame of broken lines 5 is anti-theft controller, 18 is wireless infrared or ultrasonic receipts connection circuit among the figure.2a, 2b are demoders, the 3rd, and actuator, the 7th, voltage stabilizer, the 4th, the former startup of the automobile requisite electric-controlled parts that turns round, ZH is a kind of polymeric switch among the figure, when 2 times of the electric current overrate that flows through it, it can disconnect, and when electric current recovers just often, it can recover conducting again automatically.Each line of drawing from frame of broken lines 5 is promptly represented each line that anti-theft controller is drawn in the shell 1.Form outer pig-tail wire short circuit protective circuit by ZH, D, D1, Q1, Q2, R1, R4, voltage stabilizing 1C7, R3, Q3, R2 etc. among the figure.By Fig. 1 d Fig. 1 e as seen, A, B, C, D, E, F, each outer pig-tail wire of G mutually make up short circuit respectively in twos and neither can ruin anti-theft controller J1 is connected, and its principle has here just been given unnecessary details no longer one by one.

Be also shown in by Fig. 1 c, Spark Control Computer 4 has a lot of plug specials to be locked in simultaneously in the main machine for car theft-proof device housing 1, even stealing, car agree spend high price to go automotive parts store to buy the Ignition Control computer fittings, simultaneously also very expert, model, specification to accessory are very familiar to, so can buy the Spark Control Computer (otherwise the accessory that buys is with useless) that meets former car requirement fully, then also because of a lot of special uses are inserted, joint is locked in event in the firm housing, the Spark Control Computer accessory of newly buying can't install.If someone checks each private jack that inserts the Ignition Control computer fittings after attempting outside shell these plug special pig-tail wires and special-purpose vacuum tube joint is drawn in shell vacuum lamp all cut off one by one again, we can say that so this is a kind of fantastic idea.Just think, they are in very of short duration robber's car time, and why may so how tortuous lead through each corner of vehicle be made clear and guarantee to connect errorless in panic? This is Arabian Nights seemingly.Even the people that the ins and outs of every line of Spark Control Computer are had at fingertips, to each pin in the private jack on so multi-thread and the Spark Control Computer all be connected reliably, and under the situation that does not have special-purpose vacuum lamp connector, will make and mould vacuum lamp firmly and be connected, and guarantee that sealing is also also unrealistic with vacuum socket in the Spark Control Computer.

By Fig. 1 d or Fig. 1 e as seen, have only to anti-theft controller and input cooresponding password, decoder 2a or 2b could correct decodings, and relay J could be worked, and its contact J1 could connect controlled part 4.Because it is to synchronous working with the former startup of the described automobile requisite electric-controlled parts that turns round that the fault of being made up of short circuit protection diode D ' resistance R and luminotron LED detects read out instrument automatically; and be controlled by same pair of described antitheft relay contact; therefore when LED lights; J1 certainly on the former startup of the automobile requisite electric-controlled parts that turns round; as not lighting a fire this moment; fault is certainly on the anti-theft controller in frame of broken lines 5, thereby finished the automatic detection of anti-theft controller fault and the function of demonstration with open-and-shut circuit.

When suspecting that the fault that can not light a fire goes out aspect the main machine for car theft-proof device in shell 1, input cooresponding password to anti-theft controller when can place " maintenance " position (promptly connecting the position of K1) in connection igniting K switch with function conversion controling switch K1, electromagnet 9 actions this moment, the resistance shelves effect of 10 pairs of sliding mechanical locking bolts 6 of its armature is removed, sliding mechanical locking bolt 6 can a left side (Z direction) moves and will cover 2 and open, and (sees also Fig. 1 a) so can check, keep in repair, maintain or change shell 1 interior each parts.

When damaging because of anti-theft controller can not normal ignition the time, the select switch K2 of secondary redundancy switching circuit can be got to b by original a, the redundant transfer relay J2 of secondary this moment adhesive, its contact switches to J2b by original normally closed J2a, so the standby decoder of second cover is devoted oneself to work, this moment, vehicle can be lighted a fire, and has successfully realized self-rescue when inputing cooresponding password to anti-theft controller.By principle as seen, the preceding topic of this oneself rescue is the rescue person self must have cooresponding crypto control unit.

Among the ZL92201912.6 anti-theft controller and automobile ignition coil or firing unit or electromagnetic valve are become integrated antitheft new parts with disposable the shutting of firm housing, say to have positive effect from anti-theft effect, yet, as everyone knows, anything all has the life-span, in the disposable structure of shutting, as long as anti-theft controller or the arbitrary damage of automobile component, just must a complete set ofly change, even comprise Electronics Cryptographic Keys.For resembling Spark Control Computer, the engine controlling computer that proposes among the application ... this can't but be a kind of greatest waste and sorry etc. the very expensive automobile component of price! If especially number picks up the engine controlling computer and the plug special thereof of bar pin and anti-theft controller is also together disposable shuts in housing with having described in the embodiment of the present application 2, in case failsafety are then wherein arranged, vehicle will be difficult to repair and use, and can bring the deuce to pay.Thereby it is integrated also more to demonstrate this both three parts, the separate separately again beyond thought advantage of integrated, openable main machine for car theft-proof device.

Embodiment 2; will be among Fig. 2 a by wireless infrared ultrasonic or wired acceptor circuit; the decoder of secondary redundancy structure and commutation circuit thereof; actuator; antitheft relay; outer pig-tail wire short circuit protective circuit; fault detects anti-theft controller 4 that read out instrument etc. forms and automatically by described anti-theft controller; the function conversion controling switch (also can cause it outside housing 1; do not draw among the figure); DC machine 9; orienting sleeve 10; the directly sliding rod 11 of non-rotary body; cipher electric lock that sliding mechanical locking bolt 6 is formed and engine controlling computer (being called for short MCU) or electronic controller (being called for short ECU) or igniting module (or claiming the igniting amplifier) 3 and private jack 5a thereof and plug special 5b all place in the housing 1; when will cover 2 along direction shown in the arrow vertically downward (directions X) cover on the housing 1; and then after (Q direction) passing puts in place forward; L type lock pawl 7a on the lid 2; inverted T shape lock pawl 8a just with housing 1 on L type lock pawl 7b and inverted T shape lock pawl 8b hook mutually and can not make progress (SH direction) open; at this moment; when with hand left (Z direction) (do not draw among the figure) when stirring the toggle that is connected on the sliding mechanical locking bolt; sliding mechanical locking bolt 6 will insert among the hole 8c that covers 2 inverted T shape lock pawl 8a; make cover 2 backward (H direction) move and open; after sliding mechanical locking bolt 6 left sides (Z direction) moves on to the position; motor 9 circuit control under begin left-hand revolution; (asking for an interview Fig. 2 b) is owing to motor 9 and the orienting sleeve 10 with interior square column type are fixed in the housing 1; again owing to there is the directly sliding rod of spiral shell mosquito and non-rotary body 11 negative thread in axial to match on the motor shaft; and guarantee that the two is coaxial during assembling; so result of motor left-hand revolution; to promote the directly sliding rod 11 of non-rotary body (H direction) moving linearly backward; and retaining is in the right side of sliding mechanical locking bolt 6 Y side; prevent that its right side (Y direction) from moving, thereby housing 1 is locked.Desire to open and cover 2, to engine controlling computer or the electronic controller in the housing 1 ... Deng overhauling when changing, must use cooresponding crypto control unit just can make motor 9 dextrorotations then remove non-rotary body and directly slide the barrier effect of rod the sliding mechanical locking bolt, the sliding mechanical locking bolt could right (y direction) move, lid 2 just can be opened, but the high performance of the main machine for car theft-proof device of this not only one but also each self-separation and the unexpected effectiveness that can bring thereof are conspicuous, repeat no more here.
