Abstract

The utility model relates to a cipher-type theft-proof device, which can be used for the theft proof automobiles, motorcycles and families. The utility model is composed of a plurality of cipher switch keys which are mutually connected in parallel, an alarming sound source, etc., wherein, the cipher switch keys are connected with the power supply of the automobile, a switch, an ignition lock and an ignition coil. A cipher is coded by the regular connection between the static and movable contacts of a switching key; any coding is pushed in error, an alarming device can give an alarm, and a robber is unable to break the alarming device; once broken, the alarming device can immediately give an alarm. The utility model has high theft-proof sensitivity, strong practicability low cost and easy fabrication.

Description

The vehicle cryptographic Car Burglar Alarm

The utility model is the device that prevents that automobile is stolen.

At present, automobile, motor bike are stolen of common occurrence, although people have taked countermeasure, such as assembling electronic type Car Burglar Alarm, mechanical type Car Burglar Alarm etc., because the criminal can fundamentally destroy Car Burglar Alarm so that antitheft malfunctioning.

The utility model purpose is to design a kind of cipher Car Burglar Alarm, and this theft-proof password is different and have only the car owner to grasp because of car, suffers the robber to destroy the purpose that can report to the police at once in case can also reach simultaneously.

Technical solution of the present utility model is: connect power supply E, K switch ₁, K ₂, ignition lock A, relay J, wire fuse RD and include the cipher switch key W of a plurality of lock-bits automatically parallel with one another ₀, W ₁, W ₁, W ₃, W ₄, W ₅, W ₆, W ₇, W ₈, W ₉Reach cipher switch W key Wm and each (see figure 1) of warning sound source Z, electromagnetic lock Q of lock-bit automatically.And each cipher switch key has five fixed wiring posts, on it about 1 and 2,3 and 4 be break back contact about down, centre 5 is the moving contact (see figure 2).Left break back contact and bottom right break back contact are connected on the alarm loop respectively on the selected on ﹠ off switch that is arranged as password, and the moving contact of arranging cipher switch key formerly links to each other with the bottom left break back contact of next digital switch key and and the like (be connected as the dotted line among Fig. 1, its password is 135).And the cipher switch key of selected arrangement is not that following left and right sides break back contact is respectively on alarm loop.Electromagnetic lock Q connects K switch in addition ₂, also be parallel with several cipher switch keys in alarm loop.Cipher switch key of the present utility model is installed on the vehicle body bridge instrumentation dish, and connection line and annunciator are hidden in the vehicle body protecgulum.Automatically the cipher switch key Wm of lock-bit adds projection between the break back contact of the left and right sides thereon in addition, makes two disconnected states of static electric shock punishment.

Now provide accompanying drawing:

Accompanying drawing 1 is the connection mode of the utility model component and the scheme drawing when the password number is 135

Accompanying drawing 2 is the structural representation of the utility model cipher switch key

E is power supply, K among the figure ₁, K ₂For switch, Q are that electromagnetic lock, J are that relay, A are that ignition lock, B are that ignition wire, RD are wire fuse, W ₀, W ₁, W ₂, W ₃, W ₄, W ₅, W ₆, W ₇, W ₈, W ₉For cipher switch key, Z are that warning sound source, 1,2 is that last left and right sides break back contact, 3,4 is that left and right sides break back contact, 5 is that moving contact, a are that movable contact spring under last movable contact spring, b are, c are recoil spring down.

Performance of the present utility model:

Purchase the required components and parts of the utility model, be connected between automotive engine power supply, switch, ignition lock, high-tension coil according to Fig. 1, as determining that at random its password number is during 135 (according to permutation and combination, can have various groups), practice are used, as not according to password number order button, so careless wrong all can not the igniting by that key makes car engine, but cause reporting to the police, because the movable contact spring of button makes down left and right sides static contact connect alarm loop, under the state of not sounding all clear, K closes ₁, ignition start, power supply be through K ₁, ignition lock A delivers to W ₁, W ₃, W ₅Last right contact, and through the loop of any one switch, as E → K ₁, → W ₃Go up right contact → W ₃Go up right contact → J, Z, actuation of an alarm, J adhesive, J ₂Closed, J ₁Disconnection, high-tension coil lose power supply and can't produce high pressure, and automobile can not start, again because of J ₃Closed power supply can be directly to the Z power supply, even break K this moment ₁Also can't removing reports to the police to have only by correct order presses W ₁, W ₃, W ₅(135) key or open that the car protecgulum disconnects could start a car.Destroyed for preventing Car Burglar Alarm, the utility model is contained in warning circuits such as J, Z in the car protecgulum of automobile, so press electromagnetic lock Q on the car protecgulum, the utility model is also compiled password with electromagnetic lock.Make the burglar can't open car bonnet and destroy warning circuit, the password of its electromagnetic lock of connection mode is 897 as shown in Figure 1, open car bonnet and then will press W ₈, W ₉, W ₇Key, remove password, K closes ₂Electromagnetic lock just works, otherwise also can report to the police.Want to destroy combination disk for another the burglar, have the displacement projection just inoperative slightly, warning circuit is connected in top two break back contact resiliences under the effect of pull back spring of Wm, gives the alarm, so robber's destruction wantonly also is difficult to succeed.Password number of the present utility model has a lot, and originating firm and user can encode voluntarily, all can reach same effect as long as meet the mode of connection, pulls down keyboard as long as disconnect RD as need, also can disconnect the battery power line.In addition, also can be used for motor bike and home security according to the utility model as a same reason.For preventing malfunction cipher switch key, can add error proof cover at keyboard.

In sum, the utility model is reasonable in design, is easy to make, antitheft highly sensitive, have better anti-theft effect also be difficult for destroyed, practical, cost is low, the surface structure of keyboard-type is more attractive in appearance, with in low high-grade automobile can both mate.

Claims (3)

1, a kind of connection power supply E, K switch ₁, K ₂, cutout relay J, ignition lock A, high-tension coil B, wire fuse RD the vehicle cryptographic Car Burglar Alarm, one of its feature is: it also includes the cipher switch key (W of a plurality of lock-bits automatically parallel with one another ₀, W ₁, W ₂, W ₃, W ₄, W ₅, W ₆, W ₇, W ₈, W ₉Deng) and cipher switch key Wm of lock-bit automatically, each one of warning sound source Z, electromagnetic lock Q, and each cipher switch key has five fixed wiring posts, it on about, be break back contact about down, one of centre is a moving contact; Two of feature is: the selected mode of connection that is arranged as the on ﹠ off switch of password number is that last left break back contact and bottom right break back contact are connected on the alarm loop respectively, and the moving contact of arranging cipher switch key formerly and the bottom left break back contact of next digital switch key are mutually in succession also, and the not selected on ﹠ off switch that is arranged as the password number is a following left and right sides break back contact, is connected on the alarm loop respectively; Feature three is: electromagnetic lock Q connects K switch ₂, also be parallel with several cipher switch keys in alarm loop.
