Abstract
The utility model discloses a starting motor protective circuit, which comprises a starting relay with a coil in series connection inside an igniting circuit. The starting motor protective circuit is characterized in that one end of a normally open switch of the starting relay is connected to a control end of a starting motor; the other end of the normally open switch of the starting relay is connected with a protective relay; one end of a coil of the protective relay is connected to a positive power output end of a generator; the other end of the coil of the protective relay is grounded; one end of a normally closed switch of the protective relay is connected to a positive electrode of a storage battery; and the other end of the normally closed switch of the protective relay is connected with the starting relay. The starting motor protective circuit has the remarkable advantages of simple structure, low cost and capability of ensuring the starting motor not to be damaged due to malfunction even if a driver repeatedly starts the igniting circuit or the started igniting circuit can not be closed because of igniting lock contact ablation.
Description
Technical field
The utility model belongs to Automobile Igniting Control and resist technology field, specifically, relate to a kind of when automotive ignition starts, the protection starter motor the starter motor protective circuit.
Background technology
Existing automobile igniting circuit comprises starting relay, the coil tandem of this starting relay is in firing circuit, one termination starter motor of its normal open switch, another termination storage battery positive supply, when chaufeur is connected firing circuit, the starting relay coil get electric after, the normal open switch closure, starter motor gets electric, the running of starter motor start the engine, and driving engine drives electrical generator work again.In real-world operation, because partly the startup of driving engine operation back sound is very low, chaufeur can think that driving engine does not also start by mistake after igniting for the first time is normal.Starting ignition circuit for the second time even repeatedly, at this moment, the starter motor of normal operation is triggered once more, causes that easily the unidirectional tooth of starter motor is impaired.
The shortcoming of existing starter motor circuit is: do not have a kind of install can prevent chaufeur repeatedly to start or ignition lock start burning of contact and cause can't protect the starter motor misoperation and damage.
The utility model content
For solving above technical matters, the purpose of this utility model is to provide a kind of starter motor protective circuit, even repeatedly starting ignition protective circuit of chaufeur can guarantee that also starter motor can not damage because of misoperation.
The technical solution of the utility model is as follows: a kind of starter motor protective circuit, comprise starting relay, the coil tandem of this starting relay is in firing circuit, it is characterized in that: the control end of a termination starter motor of this starting relay normal open switch, the other end of this starting relay normal open switch is connected to protective relay;
One end of this protective relay coil connects the positive supply mouth of electrical generator, other end ground connection, the positive pole of a termination storage battery of this protective relay normally closed switch, the described starting relay of another termination of this protective relay normally closed switch.
Beneficial effect: the utility model provides starter motor protective circuit a kind of simple in structure, with low cost, though chaufeur repeatedly starting ignition circuit or ignition lock start pitting of contact, can guarantee that also starter motor can not damage because of misoperation.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model provides a kind of starter motor protective circuit, comprise starting relay J1, the coil tandem of this starting relay J1 is in firing circuit, it is characterized in that: the control end of a termination starter motor 1 of this starting relay J1 normal open switch, the other end of this starting relay J1 normal open switch is connected to protective relay J2;
One end of this protective relay J2 coil connects the positive supply mouth of electrical generator 2, other end ground connection, the positive pole of a termination storage battery 3 of this protective relay J2 normally closed switch, the described starting relay J1 of another termination of this protective relay J2 normally closed switch.The positive supply mouth is D+ or N end.
Its principle of work is:
When chaufeur is connected firing circuit, starting relay J1 coil get electric after, the normal open switch closure, storage battery 3 is to the starter motor power supply, the running of starter motor start the engine, driving engine drives electrical generator work again.
Generator for electricity generation, protective relay J2 coil gets electric, and its normally closed switch disconnects; storage battery 3 can't be powered once more to starter motor; chaufeur starting ignition circuit how no matter, the storage battery triggering starter motor of can not powering has once more protected the unidirectional tooth of starter motor can be not impaired.
