Description
Technical field
The utility model relates to the automobile starting technical field, relates in particular to a kind of protective circuit of starter motor.
Background technique
The startup of motor needs the external force support, automobile starter is just being played the part of this role, starter motor is the core component of auto electric, is the critical component that guarantees the fundamental function of vehicle realization " startup ", and its reliability directly has influence on driver's use impression.But the starter motor continuous working period can not be long, automobile starter continuous firing commonly used can not surpass 30 seconds, otherwise may cause starter motor to burn.
Automobile ignition lock or circuit chance failure may cause starter motor in long working state, cause the starter motor ablation, for avoiding problems, occur, and the mode that adopts vehicle body control unit to increase startup inhibition logic realizes protection.
The control unit of engine of a new generation substantially all is designed with the control logic of starter motor protection; judge that by working staties such as monitoring motor specific axis, cams whether motor is in running order; if motor is in normal working; control unit of engine will drive to start and suppress the relay adhesive; disconnect starter motor and start loop, even guarantee that under unusual condition, starter motor can not worked yet.
The prior art software and hardware all is integrated in control unit of engine; the control unit of engine of the automobile product of early development does not have respective design; if these automobiles will increase the starting protection logic in the optimization and upgrading process; the control unit of engine that need to more renew; this is limited by cost in actual mechanical process, product development cycle is considered, normally can not realize.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of protective circuit of starter motor is provided, and prevents from causing the starter motor ablation that works long hours because of ignition lock clamping stagnation, line fault or operate miss.
For achieving the above object, the protective circuit of described starter motor, be characterized in, the protective circuit of described starter motor comprises car body controller, antitheft relay, starting relay, generator and storage battery, wherein,
Described car body controller is electrically connected to the L end of generator, described car body controller also is electrically connected to the actuating signal input end by the coil of antitheft relay, the movable contact of described antitheft relay is electrically connected to described actuating signal input end, the normally-closed contact of this antitheft relay is by the coil ground connection of described starting relay, and the normally opened contact of described antitheft relay is put sky; The movable contact of described starting relay connects described storage battery, and the normally opened contact of described starting relay is electrically connected to described starter motor, and the normally-closed contact of described starting relay is put sky; And,
When actuating signal input is arranged, and the voltage of the L of described generator end is while surpassing default time of a default voltage one, and the coil that described car body controller is controlled antitheft relay obtains electric.
Preferably, described default voltage is 14V, and the described default time is 5s.
The beneficial effects of the utility model are,
(1) protective circuit of described starter motor is monitored the state of voltage of the L end of generator by car body controller, judge that whether current starter motor is in the overtime work state, and immediately control starter motor quit work when starter motor enters the overtime work state, reached the purpose of protection starting machine;
(2) protective circuit of described starter motor relies on existing car body controller, simple in structure, relatively independent with control unit of engine, makes in the optimization and upgrading process without considering to change control unit of engine.
The accompanying drawing explanation
Fig. 1 shows the principle schematic of the protective circuit of starter motor described in the utility model.
Embodiment
Below describe embodiment of the present utility model in detail, described embodiment's example is shown in the drawings, and wherein same or similar label means same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment who is described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Fig. 1 shows the principle schematic of the protective circuit of starter motor described in the utility model, and as shown in Figure 1, the protective circuit of described starter motor comprises car body controller 4, antitheft relay 3, starting relay 2, generator and storage battery 1.
Particularly, described car body controller 4 is electrically connected to the L end of generator, described car body controller 4 also is electrically connected to actuating signal input end ST by the coil of antitheft relay 3, the movable contact 31 of described antitheft relay 3 is electrically connected to described actuating signal input end ST, the normally-closed contact 32 of this antitheft relay 3 is by the coil ground connection of described starting relay 2, and the normally opened contact 33 of antitheft relay 3 is put sky; The movable contact 21 of described starting relay 2 connects described storage battery 1, and the normally opened contact 23 of described starting relay 2 is electrically connected to described starter motor M, and the normally-closed contact 22 of starting relay 2 is put sky.
When actuating signal input is arranged, and the voltage of the L of described generator end is while surpassing default time of a default voltage one, and the coil that described car body controller 4 is controlled antitheft relay 3 obtains electric.Preferably, described default voltage is 14V, and the described default time is 5s.
The working principle of the protective circuit of described starter motor is:
Car body controller 4 detects the voltage of the L end of generator, when the actuating signal input is arranged, and when the voltage that car body controller 4 detects the L end of this generator is no more than 5s higher than time of 14V, car body controller 4 is not done action, it is electric that the normally-closed contact 32 of actuating signal by antitheft relay 3 obtains the coil of starting relay 2, thereby the movable contact 21 of starting relay 2 is connected with the normally opened contact 23 of starting relay 2, starter motor M normal operation.
When the actuating signal input is arranged; and when the voltage that car body controller 4 detects the L end of this generator surpasses 5s higher than time of 14V; think that current starter motor M has entered the overtime work state; now that the coil of antitheft relay 3 is obtained is electric for car body controller 4; the movable contact 31 of antitheft relay 3 is connected with the normally opened contact 33 of antitheft relay 3; thereby the coil losing electricity of starting relay 2; the movable contact 21 of starting relay 2 is connected with the normally-closed contact 32 of starting relay 2; starter motor M quits work, thereby reaches the purpose of protection starting machine M.
Embodiment shown in above foundation is graphic describes structure of the present utility model, feature and action effect in detail; the foregoing is only preferred embodiment of the present utility model; but the utility model does not limit practical range with shown in drawing; every change of doing according to conception of the present utility model; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet specification and illustrating contain spiritual, all should be in protection domain of the present utility model.
