Description

A kind of automobile is anti-robs antitheft alarm system

It is special that the utility model relates to warning device, relates to the automobile antikijacking burglar warning device of automobile antikijacking burglar.

At present, known automobile burglar, robbery-defence alarm are made up of siren horn, main frame, remote controller three parts, the complicated cost height of main machine structure, because of control part has remote controller control, when the driver in driving as and the robber, but driver's remote controller makes the anti-theft anti-robbery alarm device enter anti-misfortune state.Siren horn sends sound equipment simultaneously, the automotive engine parking of stopping burning, remote controller once more, alarm condition can be removed immediately, in reality, the driver in driving as and the robber, remote controller is not easy to driver operation, promptly is that the driver touches remote controller, and warning device enters alarm condition, the robber is remote controller releasing warning by force again, therefore is unfavorable for the anti-criminal to the robber.

The purpose of this utility model, provide a kind of automobile antikijacking burglar warning device, it is convenient to driver's control, when the driver is robbed in driving, the driver can touch the anti-switch of robbing very easily, the antikijacking burglar warning device can enter anti-misfortune state immediately, and siren horn sends sound equipment, and automobile can't start, operation prevents robbing switch once more, the anti-switch of robbing is ineffective, have only the driver very fast releasing to report to the police, and this device also has anti-theft feature.

Above-mentioned purpose of the present utility model is achieved like this, original power supply on the automobile, the relay of two groups of contacts, siren horn, the anti-switch of robbing, anti-theft switch, original firing circuit of automotive engine, the antikijacking burglar warning device of forming, relay coil (2) is paid with (-) and is electrically connected, coil (1) respectively with (the connecting during relay energized of first group of contact (J1) of relay, disconnect when falling), (+) positive electricity is connected in series, relay coil (1) is robbed switch (K1) access (+) that is connected in series with anti-again, the coil of relay (1) is connected in series with anti-theft switch again, be connected to relay (J2) group contact, (J2) group contact of relay (disconnects when picking up, connect when falling), be connected in series in the original firing circuit of automobile, between starting ignition switch and the circuit hot, siren horn and relay are connected in parallel.When the driver runs into the robber, touch and connect the anti-switch of robbing, at this moment, (+) positive electricity is by the anti-switch of robbing, be switched to relay coil (1), at this moment the relay coil two ends have electricity to pick up, relay (J1) group contacting has been connected positive electricity to relay again, at this moment instant robber has disconnected anti-misfortune switch, and relay can reliably pick up by the connection that picks up of (J1) group contact, forms self-insurance, simultaneously, (J2) group contact that is connected in series in the relay in the car engine ignition circuit disconnects, the circuit hot outage, and driving engine can not be worked.The siren horn that is connected in parallel on the relay two ends simultaneously sends the sound.

Automobile stop burning stop after, connect anti-theft switch, this moment is when having the people to steal car, as long as the car engine ignition circuit has, at this moment, relay can pick up again, and by the contact self-insurance of (J1) group, (J2) group contact open firing circuit, siren horn sends sound equipment, informs that the driver has the people to steal car.

Owing to adopted such scheme, the driver can make things convenient for the robber in driving makes this device enter anti-misfortune state rapidly, possesses anti-theft feature simultaneously.Main frame of the present utility model has only adopted a relay, and circuit structure is simple.

Below in conjunction with each drawings and Examples the utility model is further specified.1 2 3 4 ( B ) ( J ) ( + ) (-) ( 1 ) ( 2 ) ( J1 ) 1 ( J2 ) 2 ( K1 ) ( K2 ) ( S ) ( L ) ( J ) 、 ( K1 ) , ( K2 ) ( J ) 。

Referring to Fig. 1: relay coil (2) connects (-) and pays, relay coil (1) respectively with (J1) contact of relay (+) positive electricity that is connected in series, relay coil (1) again with the anti-switch be connected in series (+) of robbing, relay coil (1) is connected in series with anti-theft switch again, be connected with relay (J2) contact again, relay (J2) contact is connected in series between the starting ignition switch and circuit hot of original automobile igniting circuit.

Referring to Fig. 3: the anti-warning circuit figure that robs, when the driver runs into the robber in driving, touch and connect the anti-switch (K1) of robbing, positive electricity (+) connects anti-ly robs switch (K1) on and has electric current to flow through to pick up (+) positive electricity to organize the contact by relay (J1) to pick up to paying electricity (-) relay (J) through relay coil (1) (2), be switched to relay coil (1) relay self-insurance, at this moment, the instant disconnection prevents robbing switch (K1), relay can not fall yet, picking up of relay makes relay (J2) the group contact open that is connected in series in the car engine firing circuit, at this moment, the engine igniting circuit of automobile disconnects, and driving engine stops burning, at the same time, be connected in the siren horn at relay two ends in parallel, send sound and inform that automobile is robbed.At this moment, the antikijacking burglar warning device is without removing the automobile fail to start, chimes of doom can not cut off, when needing to remove when reporting to the police, touch and disconnect the anti-switch (K1) of robbing, disconnect (+) electricity, fall because of relay outage loss of excitation this moment, (J1) group of relay disconnects, relay can not self-insurance, locates full state, the falling of relay, make relay (J2) the group contacting that is serially connected between the engine igniting circuit, it is normal that engine igniting circuit recovers, and because of relay (J) (+) positive electricity disconnects, the siren horn sound that is parallel to relay (J) stops, connect positive electricity, alarm release.

Referring to Fig. 4: circuit diagram when being anti-theft alarm.After the parking driving engine stops burning, connect anti-theft switch (K2), stealing car ignition lock switch (S) as the people connects, (+) positive electricity is switched to relay coil (1) through anti-theft switch (K2) at this moment, this moment, relay had electric current to flow through to pick up, (J1) the group contacting has been connected positive electricity (+) through relay coil (1) again, the relay self-insurance.Simultaneously, the siren horn that the is connected in parallel in relay sound that makes sound is connected in series in relay (J2) contact open in the automobile igniting circuit simultaneously, has also disconnected the firing circuit of automotive engine simultaneously, the sound that driving engine fail to start, siren horn are sent informs that the driver has the people to steal car.Anti-theft alarm such as need are removed.At first, disconnect anti-theft switch (K2), disconnect (+) positive electricity and install immediately, at this moment, relay (J) loss of excitation falls, relay (J1) contact falls disconnection, relay can not self-insurance, and (J2) group contact of relay falls connection, has recovered the firing circuit of automotive engine, the siren horn that is parallel to relay simultaneously loses positive electricity (+) sound to be stopped, and anti-theft alarm is removed.
