Abstract

An automobile multifunction alarm is an automatic alarm device, which can prevent the driver from causing trouble when the driver drives after drinking. The utility model can also prevent the car from being stolen. The utility model uses the characteristics of the gas sensing resistance and suction device to measure the alcohol vapor exhaled by the drunk driver (that is to say the gas contained alcohol). The utility model can start working when the concentration of the gas measured is greater than 0.05%, and can cut the circuit of the automotive ignition system, so the motorcar can not start up. Meanwhile, the utility model issues the audible and visual alarm signal. In addition, the automobile multifunction alarm has the function of bugging. When the car door is opened by force, a flip flop of the door can issue the signal. Then the start-up source of power can be cut, so the motorcar can not start and the utility model issues the audible and visual alarm signal at the same time.

Description

Automobile multifunction alarm

The utility model is to use for motor vehicles, is specifically related to drive when intoxicated accident and prevent the warning device voluntarily that automobile is stolen of a kind of driver of preventing.

Mostly the at present existing measurement driver who makes probe with the gas sensor detection instrument of driving when intoxicated is to do the measurement source by spreading naturally of tested gas, and it is long to exist the time interval, poor sensitivity, the shortcoming of function singleness.

The purpose of this utility model provides a kind of fast detecting fume and has the automobile multifunctional warning device of anti-theft feature concurrently.

The utility model is to realize like this, the quick measuring sonde of wine is housed in the quick measurement mechanism of wine, when the driver opens the switch connection power supply, during the ready to start vehicle, air pump in the quick probe of wine is started working, when the element in the quick probe of wine runs into the fume concentration that sprays in driver's mouth 〉=0.05, resistance descends rapidly, the signal that is produced is the input executive circuit after amplifying circuit amplifies, automobile igniting circuit is cut off in electromagnetic relay action in the executive circuit, automobile can not be started, and sound, light alarm circuit are connected, give the alarm.

In addition, in the burglar alarm, the latent flush type switch of keeping away is set, as thief during with car door opening at car door, switch disconnects, and, cut off automobile igniting circuit and connection sound, optical alarm circuit by electromagnetic relay with the signal of its generation input executive circuit, send warning.

Fig. 1 is a circuit diagram of the present utility model

Fig. 2 is the quick measuring sonde structural drawing of wine of the present utility model

The utility model concrete structure is by the quick amplification circuits of wine (I), antitheft amplification circuits (II), and executive circuit part (III) is formed (see figure 1).

The quick warning part of wine:

After opening ignition switch (G), air pump (M) work in the quick probe of wine (Fig. 2), when the quick resistance of the wine in the probe (W) measures fume concentration greater than 0.05% fume body, the quick resistance value of wine descends, after the amplifying circuit that the signal of its generation is made up of transistor (GB1, GB2, GB3) amplifies, be input to executive circuit, make in the executive circuit electromagnetic relay (J1) conducting and by (J1-1) self-locking, (J1-2) point of release fire coil (L) opens circuit at this moment, makes the automobile can not ignition trigger.Meanwhile (J1-3, J1-4) connects (U2, V2) acousto-optic circuit connected, and gives the alarm; Sound in the car, light show that (U1, V1) also gives the alarm simultaneously.As ignition switch (G) is turned back the original place, alarm can disappear.In addition because the time-lag action of the time relay (Js), make the quick alarm of wine open 1～2 minute after, the contact of the time relay (Js-1) discharges, and air pump (M) is quit work automatically.If fume disappears, then can start once more.

The structure of the quick probe of wine as shown in Figure 2, (1) is the quick resistance of wine, is positioned at the centre of probe, (2) are the shell body of the quick probe of wine of the horn-like opening of garden cylindricality, (3) are air pump (M).

This probe also can be made the quick alarm of torch tubular portable wine, and its structure is at the rear portion of the quick probe of wine, the sound and power supply in quick amplifying circuit of the wine of packing into and the executive circuit.

The burglar alarm part:

Burglar alarm appliance mains switch Kf is connected.During car door opening, be arranged on the spring contact formula of bumping door switch (Ka-1, contact disconnection Ka-2) on the car door, on the base stage of BG4, produce Ib through (BG4, BG5 BG6) amplify back input executive circuit, at this moment (J1) adhesive and by contact (J1-1) closed back self-locking, contact (J1-2) discharges ignition coil L is opened circuit, and this just makes automobile start, meanwhile contact (J1-3, J1-4) closed connection sound, (V2, U2) alarm circuit gives the alarm light.

Each components and parts effect division is as follows:

(1) the quick resistance of GM--wine: after GM detected the fume molecule, the decline of the resistance value of GM has just produced difference current made the GB1 base stage obtain base current, and makes the BG1 conducting;

(2) BG1--transistor: detected GB resistance descended to be caused BG1 base stage Ib and makes and produce Ic after the BG1 conducting and remove to trigger BG3;

(3) BG2--transistor: when the fume molecule disappears or during fluctuation, Ib is reduced or can't make the BG1 conducting when equalling zero the time, and BG2 replacements in parallel with BG1 BG1 works, no matter the external world has or not the generation of fume molecule at this moment, and its topworks still works;

(4) BG3--transistor: the Ic of BG2 is amplified the work of output shake-up relay;

(5) CP1--crystal diode: BG3 amplified current Ic3 is outputed to relay (J1), make (J1) action;

(6) J1--relay: driving J1-1 and J1-2 closure after the J1 adhesive or disconnecting J-1 is the self-lock switch contact of J1, and J2 is the power contact that switches on or off of automobile ignition coil L;

(7) Js--mechanical delay relay: utilize the mechanical speed change motion principle, press rotating ratio size and decide delay time length, the back of can on time delaying time behind the setting up time drives the action of Js1 contact, connection motor M or cut off the electricity supply;

(8) M--motor: be to draw the pump bowl power that the fume molecule is used;

(9) V1, V2: acoustic alarm element;

(10) U1, U2: light alarm element;

(11) antitheft amplifying circuit (II) is similar to the amplifier section of the quick amplifying circuit of wine (I), has only some differences, and the producing method of Ib is different with GM; The Ka-1 of antitheft amplifying circuit or Ka-2 are disconnect, and the BG4 base stage is introduced positive potential by R when disconnecting circuit, then produces Ib, and Ib makes the BG4 conducting and produces Ic afterwards, and the function of each element is with the amplifier section of the quick amplifying circuit of wine later on;

(12) quick amplifying circuit of wine (I) and antitheft amplifying circuit, in parallel by J1 with the power cathode realization, when difference current, just output to J1 separately, make the J1 action;

(13) executive circuit (III) joins with quick amplifying circuit of wine and antitheft amplifying circuit by J1, accepts its difference current and makes the action of executive circuit element;

Easy to use for safety and driver, the power switch Kf of anti-theft warning circuit can be located at the shelter of body exterior or directly be located on the door lock of automobile.

Characteristics of the present utility model are, this device namely can be used as the quick alarm of wine and can be used for again preventing that automobile is stolen, volume is little, easy for installation, have fast, effective characteristics are guaranteed vehicle safety, and simultaneously the utility model can be made separately the quick alarm of torch tubular portable wine and check driver's use of driving when intoxicated for the traffic aufsichtsrat.
