Abstract
An electromagnetic flame-out device for car is composed of casing, holding coil, sucking-pulling coil, armature, protecting water-proof rubber sleeve and connecting rod. It features that a self-power time controller consisting of relay, FET, capacitor and resistors is connected with said holding coil and sucking-pulling coil to control the time of holding coil, preventing high internal temp.
Description
Technical field: electromagnetic flame-out means used for automobile of the present invention belongs to automobile-used extinguisher, and is particularly electromagnetic flame-out means used.
Background technology: existing electromagnetic flame-out means used for automobile since the pull in winding current"on"time in the extinguisher be directly to control by the driver's operation ignition lock.When point of ignition is longer, the easy Yin Gaowen of pull in winding in the extinguisher and damaging.
Summary of the invention: the purpose of electromagnetic flame-out means used for automobile of the present invention provides a kind of pull in winding in electromagnetic flame-out means used current"on"time can time-controlled electromagnetic flame-out means used for automobile.Electromagnetic flame-out means used for automobile of the present invention is by shell, keep coil, pull in winding, armature, the water proof rubber sheath, formations such as connecting rod, be characterized in: at pull in winding and keep and be connected in the coil circuit by relay, field effect transistor, electric capacity, the self-powered that resistance is formed, control circuit when controlled is controlled pull in winding, circuit when wherein the electric capacity shunt resistance is formed a control, and the moving contact that passes through relay is connected the base stage of field effect transistor, field effect transistor series connection pull in winding, ignition lock by relay connection automobile comes the charge or discharge state of control capacitance by the moving contact of relay.Principle of the present invention is to utilize the mode of operation of the ignition lock control relay of automobile, the charging and discharging state of circuit during the control formed with on-position of a relay control capacitance, resistance, the time during control of circuit during the parameter of electric capacity, resistance self decision control, the turnon time of circuit discharging time control field effect transistor during with control, thereby the work-hours of control coil.
Because the position difference of the flame-out handle on the existing electromagnetic flame-out means used for automobile injection pump, to such an extent as to the pulling direction difference of flame-out handle, so the method for work of extinguisher has two kinds.First kind is to stop working handle in the fuel feeding position, when vehicle parking is flame-out, needs to inhale and draw flame-out handle to leave the fuel feeding position; Second kind is the flame-out handle fuel feeding position of not being everlasting, and when vehicle launch, needs to inhale and draw flame-out handle to the fuel feeding position.
Electromagnetic flame-out means used for automobile of the present invention circuit control pull in winding and current"on"time of keeping coil during by control in first kind of extinguisher used, make flame-out handle leave the sufficiently long time of fuel feeding position, coil quits work behind engine off, and flame-out handle is got back to former fuel feeding position.The pull in winding of described electromagnetic flame-out means used for automobile and keep connect the respectively collecting electrode of two field effect transistor of coil, by two moving contacts of relay, two electric capacity in parallel, two the normally closed interface series resistances of relay and the base stage of field effect transistor, two electric capacity are respectively by the normally closed interface shunt resistance of relay, often open interface and connect power supply for two of relay, relay connects automobile ignition switch, the emitter of described two field effect transistor, relay and two electric capacity common grounds.
Electromagnetic flame-out means used for automobile of the present invention current"on"time of circuit control pull in winding during by control in second kind of extinguisher used, suction draws flame-out handle behind the fuel feeding position, continue the flame-out handle of absorption coil to the engine off and quit work by keeping coil, flame-out handle is got back to original position.Relay in parallel behind electric capacity of relay moving contact series connection of described electromagnetic flame-out means used for automobile, the base stage of often opening a resistance connection of interface series connection field effect transistor of described relay, the normally closed interface of relay connects power supply, what another resistance connected relay often opens interface and power supply, and the emitter and collector of field effect transistor connects pull in winding and power supply respectively.The collecting electrode of field effect transistor with described electric capacity, relay, keep the common power connection negative pole of coil.
Because the capacitance discharges time is constant, so the electrical working time of pull in winding also is constant, reaching electromagnetic flame-out means used pull in winding current"on"time can time-controlled requirement in the design of electromagnetic flame-out means used for automobile of the present invention.Owing to suitably controlled the current"on"time of pull in winding, guaranteed that the extinguisher internal temperature can not raise.Effectively raise the reliability of electromagnetism extinguisher, prolonged the service life of electromagnetism extinguisher.
The electrical block diagram that description of drawings: Fig. 1 uses at second kind of extinguisher for the present invention.
The specific embodiment: with reference to shown in Figure 1: keep coil L1 and connect automobile ignition switch A point, series connection field effect transistor Q1 on pull in winding L2, relay J 1 pull in winding L2 in parallel and field effect transistor Q1, relay J 1 in parallel behind the relay moving contact 1 series capacity C1, the base stage of relay normally open interface 2 series resistance R1 and field effect transistor Q1, resistance R 2 connects relay normally open interface 2 and power cathode, and the normally closed interface 3 of relay connects power supply.The emitter and collector of field effect transistor Q1 connects pull in winding L2 and power cathode respectively.Circuit anode A point and starter motor splicing, circuit negative pole connect negative post of storage battery or tower iron.In the utility model, the working current of keeping coil L1 is little, and by automobile key igniting direct control loop current, pull in winding L2 electric current is big, by starter motor relay control current loop, and circuit is finished control to pull in winding L2 work-hours during the control of being made up of capacitor C 1 and resistance R 2.When automobile is starting, turn on key ignition switch, make and keep coil L1 generation current return, generate an electromagnetic field, Deng pull in winding L2 energising armature is adsorbed, automobile starting motor relay work when ignition lock is screwed to enable position, the work of switching on simultaneously of starter motor and this circuit, at this moment pull in winding L2 one end get electric, capacitor C 1 charging simultaneously, relay J gets electric generation current return and adhesive, relay moving contact 1 and normally closed point 3 are disconnected and normal 2 closures of making war, capacitor C 1 is charged and is obtained electric current to R1, R2 flows through, and field effect transistor Q1 gets positive bias and conducting, pull in winding L2 produces current return, suction draws armature to draw in, and armature one end is connected with the flame-out handle of injection pump, and control injection pump fuel feeding starts, this moment capacitor C 1 discharge off, pull in winding L2 outage.When needs were flame-out, automobile ignition switch was closed, and kept coil L1 outage no current loop, and the absorption of armature non-electromagnetic field and discharging is shifted armature and flame-out handle onto the oil-break position simultaneously by retracing spring, and vehicle is flame-out to stop.Working in reciprocating mode like this reaches the startup of vehicle and flame-out.
