Pipe；
Certification is identified in the case of in the first order, and the bolt is moved downward together with sliding block so that the dentation
With the tooth-like recesses contact, when the shape of the dentation is adapted with the tooth-like recesses shape, bolt after
It is pushed away under continuous until the dentation and tooth-like recesses snaps together, when the dentation and tooth-like recesses complete one
During cause, projection portion and the groove part on the opposing party corresponding position of a side agree with completely, when the light to penetrating photoelectric tube 16
When being blocked completely, the described pair of output signal for penetrating photoelectric tube is high level, if all export high level to penetrating photoelectric tube,
Secondary authentication is completed at this time；
Three-level authentication structures include the aperture 12 being arranged on inserted block, and the aperture is directed at photoelectric reading code device, and different is small
Hole arrangement position represents different codings, then the coding aperture that the code reader on socket is read passes to the coding read
Judge identification device, judge that the code received and the code to prestore are compared identification device, be to alarming on vehicle if meeting
System sends out one and meets signal, completes three-level certification at this time；
Second verification could be carried out when completing first level verification, and three level verifications could be carried out after completing second verification, when one,
2nd, three level verifications after the completion of, stop alarm.
In the present embodiment, authentication three times is passed sequentially through when safety belt bolt is inserted into safe carrying spigots, only three times
Certification is all by can just eliminate the voice prompt of alarm system, not so by lasting alarm until being inserted into qualification in socket
Until bolt.The process of level-one certification is that concaveconvex structure is made in the both sides of safety belt bolt, concaveconvex structure and safe carrying spigots
When the billiards structure of both sides matches, bolt can move down, when moving down about 3mm, bolt front end and socket back
End in contact starts secondary authentication at this time.Secondary authentication is divided into master authentication and secondary certification, master authentication by bolt front end sawtooth pattern
It protrusion and is completed in the sawtooth pattern groove of safety belt socket bottom, secondary certification is by being mounted on 9 of socket bottom to penetrating photoelectricity
Pipe is completed.The rectangular aperture on elastic lock locking latch when bolt is smoothly inserted within socket on socket, three-level are recognized
Card starts, and the code-reading apparatus in socket reads the position of aperture accomplished fluently in advance on bolt, the various combination shape of this position at this time
Into different codings.Think that this bolt is lattice joined together by this vehicle if this coding is consistent with the coding being pre-stored in socket circuit
Bolt, decision circuit provide one and meet signal elimination alarm at this time.Otherwise, alarm continues, and instrument system is persistently alarmed.It is described
Alarm system alert icon on the dash panel and interior original loudspeaker to be set to alarm.
Embodiment 2
The present embodiment can anti-fraud automobile safety belt alarm device, on the basis of embodiment 1, the inserted block is equipped with
Rectangular aperture 13, the socket is interior to be equipped with Spring lock catch, and after the completion of level-one certification, secondary authentication, Spring lock catch is inserted into square
In shape opening, and then locked bolt.
In the various embodiments described above, the output to penetrating photoelectric tube positioned at socket bottom it is ternary respectively as three with
Door input signal, this three with door output and as the input signal with door, last output Vout1 is nine to penetrating light
The output signal phase of fulgurite and result.The safety belt connecting portion is equipped with the opening 11 that safety belt passes through.
In the various embodiments described above, the output to penetrating photoelectric tube positioned at 2 bottom of socket it is ternary respectively as with door
17th, 18,19 input signal, this three with door output again as the input signal with door 20, last output Vout1 is nine
A output signal phase to penetrating photoelectric tube and result.
The operation principle of the utility model is that certification is identified when safety belt bolt is inserted into socket, if what is be inserted into is
For bolt on this vehicle then to one certification of alarm system on vehicle by signal, this signal notifies the alarm system on vehicle to cancel alarm
Sound and light signal, if be inserted into be other bolt, then certification will not be provided by signal, alarm system continues to report
It is alert, until passenger is correctly inserted into the safety belt bolt on vehicle.
It needs to pass sequentially through three-level certification when safety belt bolt 1 is inserted into safe carrying spigots 2.Only pass through all certifications
Just it is considered that the safety belt bolt being inserted into is approved.So as to ensure that the reliability of this safety band alarm device.
When safety belt bolt is completely inserted into socket and 9 of locking and socket bottom end are all high electricity to penetrating photoelectric tube output
Usually, illustrate that first and second grade of certification passes through, will then carry out third level certification, third level identification certification is by bolt
Aperture position reads coding.Different aperture arrangement positions represent different codings, this encodes and be pre-stored in safety belt and inserts
Coding in mouthful is compared, once comparing successfully, it is the bolt being connected on safety belt on this vehicle to illustrate what is be inserted into, and certification is led to
It crosses.
The principle of photoelectric reading code device is：Porose position light can be to pass through light is by the corresponding position of opposite at this time
Photoelectric tube receives, and exports high level signal, may be defined as 1.On the contrary, non-porous position light cannot pass through, opposite corresponding position
On photoelectric tube cannot receive optical signal, export low level signal, may be defined as 0. different 1,0 combination and be formed one group
Binary code, this yard as and the input signal that is compared of the binary code that is pre-stored in socket circuit.
The above is only the preferred embodiment of the utility model, is not intended to limit the utility model, it is noted that
For those skilled in the art, it under the premise of the utility model technical principle is not departed from, can also do
Go out several improvement and modification, these improvements and modifications also should be regarded as the scope of protection of the utility model.
