The utility model adopts electromagnetic relay as function unit, has improved anti-interference resistance, reliable operation; And the automobile primary circuit between be in series with isolation diode, eliminated the interference of the utility model to primary circuit.It is simple in structure, and is with low cost.

Description of drawings

Fig. 1 is the electrical block diagram that the utility model reaches the original circuit part of connected automobile when using.

The specific embodiment

Referring to Fig. 1, it wherein in the long and two-short dash line frame circuit diagram of the present utility model, comprise five relay J 1, J2, J3, J4, J5, coil two ends in relay J 1 are parallel with delay capacitor C, this control setup has positive-negative power end V+ and V-, electrical generator coupling end D+, two start end on and ST, mouth out1 and out2, the diode D1 of power positive end V+ forward-, series is connected with an end of the open contact of the open contact of relay J 1 and J5 respectively, the other end of J5 contact is as out2, D+ and two diode D2, the positive pole of D3 connects, the negative pole of D2 is connected with the normally closed contact of J4 one end, the other end is connected with power cathode V-with J5 coil series connection back, coil one end of J4 is connected another termination V-with an end of the normally closed contact of J5; The negative pole of D3 with meet V-after the coil of J1 is connected; Start end on meets V-successively with after the coil of the diode D4 of forward and J2 is connected, and the normally closed contact two ends of J2 are connected with contact one end of J1 and J3 respectively; Start end ST meets V-successively with after the coil of the diode D5 of forward and J3 is connected, and the contact of D5 and J3 coil also is connected with the other end of the normally closed contact of J4, and the other end of the contact of J3 is connected with mouth out1.

Above-mentioned each element all is loaded in the box body, and described power end V+ and V-, generating utmost point coupling end D+, start end on and ST, mouth out1 and out2 all draw described box body by connection terminal.

In Fig. 1, give and the utility model bonded assembly circuit diagram, out2 end of the present utility model is connected with the coil of the starting relay JQ of starter M, out1 is connected with the coil of electromagnet DT, V+ is connected with the both positive and negative polarity of electrical generator G with power supply B respectively with V-, start end on and ST respectively with automobile on key switch K1 be connected with K2.The intermediate ends of electrical generator G is connected with D+.Illustrate that with reference to this figure principle of work of the present utility model is as follows:

When needing fire an engine, at first connect K1 with key switch and make war, " ON " has electricity at this moment, and the J2 adhesive disconnects normally closed contact, and mouth out1 is no-output voltage under the effect of J1, J2, and electromagnet DT is failure to actuate.Then key switch is connected the K2 switch, and " ST " has electricity, the J3 adhesive, and normally closed contact disconnects, out1 no-output voltage.The voltage of " ST " end passes through the normally closed contact disconnection of the normally closed contact of J5 with J4 simultaneously, removes the control of electrical generator " D+ " end to J5, and out2 exports no-voltage.The voltage of K2 is connected starter M by the normally closed contact of starting relay JQ, makes the starter running.After the rotation of driving engine G, electrical generator D ⁺The voltage of end can not be controlled J5 because of the J4 adhesive, simultaneously with the J1 adhesive, and the open contact closure.When starting successfully, K2 disconnects back J3, J4 and discharges because of dead electricity, the closing of contact, and D+ voltage makes the J5 adhesive, and the voltage of battery B passes through the closed normally open contact of J5 with the JQ adhesive, cuts off the control to starter M.When accidental switch " K2 ", because of the J5 adhesive, normally closed contact disconnects, and J4 is in and discharges voltage that attitude makes out2 output with the JQ adhesive, contact open and can not make voltage arrive starter M, thus prevent to damage driving engine and starter.

When needing to stop working, K1 is disconnected, the J2 dead electricity discharges the normally closed contact closure, cell pressure makes electromagnet DT adhesive by J1, J2, J3, and the pulling oil stopping handle makes engine off, the electrical generator G generation outage of flame-out back, the D+ no-voltage, J1 discharges and cuts off the electric current that leads to electromagnet DT, and electromagnet DT resets, and finishes a working cycle.

The effect of cond C is to make the burnout time prolong one section to guarantee safety, and diode D1-D5 is in order to eliminate the interference of control setup to power circuit.
