Description

A kind of mechanical lock constituting electronic circuit loop

Technical field

The disclosure relates generally to electronic anti-theft technical field and in particular to electric vehicle anti-theft technical field, and more particularly, to one Plant the mechanical lock constituting electronic circuit loop.

Background technology

Electronic anti-theft typically to protect private property not invaded using systems such as sound magnetic, radio.Tuning fork is only shaking Swing and under frequency same case, just cause resonance.Sound magnetic system (acousto magnetic) exactly applies this physical principle, Realize the operation of almost zero wrong report.When the sound magnetic system label being fixed on commodity enters the detection zone of system, can produce altogether Shake, but only receive the resonance signal (every 1/50 second once) of continuous four times in receptor after, system just can send warning.Sound The characteristic of magnetic system be antitheft verification and measurement ratio high, almost zero wrong report, not by the shielding of metal masking foil, anti-interference be good, protection is gone out Mouth wide (single set system is the widest to protect 4 meters).Radio frequency system (radio frequency, rf) is come out existing more than 30 year History, is one of electric theft-proof system of relatively early application.It adopts radio frequency to launch as system and receives detection signal, inspection Generally 7.x～8.x megahertz of measured frequency scope.The verification and measurement ratio of radio frequency system generally 80% about.Because it is anti- Robber's label is ring coil type, so much similar to label frequency coil article or electronic product all can trigger system, draws The wrong report of the system of rising.And radio frequency system is shielded by metal masking foil completely, anti-theft tag is close or is pasted onto gold Belong to and can make tag defeat on masking foil, cause system to fail to report.

Electric vehicle anti-theft is specially to design the gps burglar alarm using to electric motor car motorcycle typically using gps alarm Tracker, but the price pin of gps alarm is higher for most people, and it is cheap that this is accomplished by a kind of price, and effectively Burglar alarm.

Content of the invention

In view of drawbacks described above of the prior art or deficiency are it is desirable to provide a kind of mechanical lock constituting electronic circuit loop.

In a first aspect, a kind of mechanical lock constituting electronic circuit loop, have and lock including u-shaped lock, the one of described lock Manhole and circular groove are provided with individual side, are provided with the contact connected with anti-theft circuit in described circular groove and open Close, described contact switch includes insulating spacer, and described insulating spacer upper end is connected with spring compressor, the lower end of described spring compressor It is fixedly connected with metal bar, be connected by spring between described metal bar and described insulating spacer, the underface of described metal bar It is provided with hard contact；When described u-shaped lock has and inserts in described lock, described u-shaped lock tool extrudes described contact switch, antitheft Circuit ON.

The technical scheme being provided according to the embodiment of the present application, sealed by lockset and lock, burglar alarm can be connected Circuit, if electric motor car or motorcycle are stolen, can send alarm to remind car owner.

Further, the two ends length of described lockset is different, and the end of the longer one end of described lockset is provided with snap bayonet socket, The diameter of the shorter one end end of described lockset is less than its longer one end.Sealed by lockset and lock, lockset is shorter One end extrusion spring cap, makes metal bar contact with hard contact, so that anti-theft warning circuit is connected, electric bicycle or rub When motorcycle is stolen, this metal bar is separated with hard contact, and anti-theft warning circuit disconnects and sends warning.

Further, described hard contact includes determining sheet metal and dynamic sheet metal, described determines sheet metal and described dynamic metal It is fixedly connected by insulated spring between piece, the described bottom determining sheet metal fixed installation and described circular groove；Described lockset Two ends length different, the end of the longer one end of described lockset is provided with the snap bayonet socket of horizontal direction, and described lockset is shorter The diameter of the diameter of one end one end longer with described lockset is identical.Sealed by lockset and lock, make to determine sheet metal with dynamic Sheet metal contacts, and connects anti-theft warning circuit, if car is stolen, anti-theft warning circuit disconnects, and sends warning.

More further, be provided with described lockset on the adjacent side in side of described manhole be provided with two big Little identical through hole, the distance between two described through holes are equal to the distance between described u-shaped lock tool two ends.Ride in car owner During, lockset is inserted in described two through holes, will not trigger warning circuit.

In sum, this utility model can effectively be directed to electric motor car or motorcycle stolen when, send alarm, and Reliable and stable, cheap, disclosure satisfy that vast consumer.
