The inventor finds to have following problem in the existing technology at least: in the process of engine start; A moving-wire that connects storage battery to starter motor will bear bigger electric current at short notice; And the wave range of starting current is very big, and the fus protection can't be set on a moving-wire.The starting process of motor is very short, and after the engine start, starting circuit is not broken off, and rising also can be charged on the moving-wire, the hidden danger that can exist the moving-wire overcurrent to cause wire harness to burn.
The model utility content
The utility model provides a kind of vehicle launch circuit, in order to solving in the existing technology after the engine start since rise on the moving-wire still charged, the problem that has caused moving-wire may overcurrent to burn.
For realizing above-mentioned purpose, the technological scheme of the utility model is following:
A kind of vehicle launch circuit; Comprise storage battery, ignition switch, the starter motor that is used to pilot engine and control the starter relay of this starter motor work; Also comprise: control the magnetic switch of often opening that said starter motor is connected with said storage battery, and the controller that the said magnetic switch of control is broken off after said engine start;
Said ignition switch, storage battery, magnetic switch and controller series connection constitute a loop.
Said controller comprises a controllable normally closed switch, and said normally closed switch is connected with the control coil of said magnetic switch.
Said normally closed switch is a normally closed time delay relay.
Said controller is connected with the signals of rotational speed sensor of motor.
Said controller is connected with the neutral point signal line of said motor.
The vehicle launch circuit of the utility model is controlled the magnetic switch that starter motor is connected with storage battery through being provided with, and is controlled a controller of this magnetic switch according to the working state of starter motor.When motor has started, break off magnetic switch at this monitoring control devices, realized having protected the purpose of moving-wire, eliminated the potential safety hazard on the moving-wire to break off being connected of starter motor and storage battery.

Embodiment
The exemplary embodiments that embodies the utility model characteristic and advantage will be described in detail in following explanation.Be understood that the utility model can have various variations on various embodiment, the scope of its neither disengaging the utility model, and explanation wherein and appended accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the utility model.
In the technological scheme of the utility model, the magnetic switch often opened that the control starter motor is connected with storage battery is set in the vehicle launch circuit; And according to a controller of the working state of starter motor control magnetic switch.When this controller is judged motor and has been started, then break off this magnetic switch, to break off being connected between this starter motor and the storage battery, realize after the engine start playing the overcurrent protection of moving-wire.
Fig. 2 is the structural representation of the vehicle launch circuit of the utility model, and this circuit mainly comprises storage battery 21, ignition switch 22, starter relay 23, starter motor 24, the magnetic switch of often opening 25 and controller 26.
Wherein, Storage battery 21, ignition switch 22 and starter relay 23 series connection constitute a starting control loop; This loop is connected to the ST gear of ignition switch 22, and the contact of starter relay 23 connects the control switch of starter motor 24, and this starting control loop was connected when ignition switch 22 was in the ST shelves; Starter relay 23 make contacts, the control switch of connection starter motor 24.
Comprise a controllable normally closed switch in this controller 26, this normally closed switch can be a normally-closed contact, and its control coil with magnetic switch 25 is connected.The trigger condition that the normally closed switch of this controller 26 breaks off is that motor has started this condition, and it is in closed state under other situation.
This controller 26 is judged whether motor has started and can be adopted multiple mode, as can these controller 26 signals being connected to the speed probe of motor, judges according to the rotating speed of motor whether motor starts; Perhaps, can this controller 26 be connected with the neutral point signal line of motor, judge according to the neutral point signal whether motor starts.
Below the working principle of this vehicle launch circuit is specifically described.
During vehicle, ignition switch 22 is positioned at the ST gear in starting, and the starting control loop that this moment, storage battery 21, ignition switch 22 and starter relay 23 constituted is connected, and the make contact of starter relay 23 has been connected the control switch of starter motor 24.Simultaneously, the loop that storage battery 21, ignition switch 22, magnetic switch 25 and controller 26 constitute is also connected, and the make contact of magnetic switch 25 has been connected storage battery 21 and starter motor 24, and starter motor 24 is started working, and drives engine start.
After engine start; When this controller 26 is judged motor and has been started; Break off the normally closed switch of self, then the loop of storage battery 21, ignition switch 22, magnetic switch 25 and controller 26 formations is also broken off, and magnetic switch 25 is broken off its contacts; Broken off being connected of storage battery 21 and starter motor 24 thus, realized after engine start, protecting playing a moving-wire.
Further, when controller 26 breaks off in control magnetic switch 25, for avoiding magnetic switch 25 under the situation that band carries, to break off suddenly its contact is caused damage, this controller 26 can adopt the mode of time-delay to break off magnetic switch 25.Promptly the normally closed switch of this controller 26 is set to a time delay relay; This controller 26 is after judging transmitter and having started; Again magnetic switch 25 was broken off as about 10 seconds through this time delay relay time-delay a period of time, avoided infringement the contact of magnetic switch 25.
In the technological scheme of the utility model, control the magnetic switch that starter motor is connected with storage battery through being provided with, and control a controller of this magnetic switch according to the working state of starter motor.When motor has started, break off magnetic switch at this monitoring control devices, realized having protected the purpose of moving-wire, eliminated the potential safety hazard on the moving-wire to break off being connected of starter motor and storage battery.
Those skilled in the art should recognize change and the retouching of under the situation of scope that does not break away from the appended the utility model that claim disclosed of the utility model and spirit, being done, and all belong within the protection domain of claim of the utility model.
