The utility model relates to starter motor, specifically, relates to the starter motor with initiatively engagement capability.
Background technique
Fig. 1 is the sectional view of current existing auxiliary meshing type starter, in FIG, auxiliary meshing type starter motor being applied to starting torque adopts following structure: slow down by the running torque of the armature 11 in speed reducer 2 pairs of motors 1 and increase running torque, the actuation gear 6 being installed on output shaft 5 by one-way element 4 is undertaken driving by above-mentioned motor 1 and rotates.
In conjunction with consulting Fig. 2, auxiliary meshing type starter comprises motor 1, magnetic switch 3 and relay 12.In auxiliary meshing type starter, magnetic switch 3 comprises sucking coil 36, hold-in winding 37 (sucking coil 36 and hold-in winding 37 are arranged on coil rack 43), be trapped among the outside of sucking coil 36 and hold-in winding 37 circumferentially, form the body 7 of a magnetic circuit part, be located at the rearward end of sucking coil 36 and hold-in winding 37, form the only seat 16 of a magnetic circuit part, be configured in the inner circumferential of sucking coil 36 and hold-in winding 37, the plunger 8 be free to slide vertically, to the Returnning spring 14 that plunger 8 forwards exerts a force, be arranged on the movable contact 17 of plunger 8 rear end, and relatively movable contact 17 arranges and carries out with outside wiring a pair stationary contact 30a being connected, 30b.By carrying out being energized to the sucking coil 36 of this magnetic switch and hold-in winding 37 and produce the electromagnetic attraction in B direction in Fig. 1 in plunger 8, due to this electromagnetic attraction, the upper end of the shift fork 9 coordinated with above-mentioned plunger 8 is moved in direction (shown by arrow B direction) direction that is mobile, left side in Fig. 1, its lower end to the right, therefore, actuation gear 6 on one-way element 4, output shaft 5 is applied to the power of left direction (marked by arrow A direction) movement in Fig. 1, so actuation gear 6 moves to the direction of engaging with the flywheel ring gear 10 of motor.
Continue to consult Fig. 2, the positive terminal of storage battery 13 is connected with the terminal 18 of magnetic switch 3, negative pole end ground connection or be connected with the terminal 31 of motor 1.The relay 12 that terminal 50 to magnetic switch 3 carries out power-on switch comprises: the terminal 50c be connected with storage battery 13, the contact 32 be connected with terminal 18, and to the coil 34 that contact 32 and contact 33 control.The terminal 50c being positioned at coil 34 one end is connected by the positive terminal of key switch 35 with storage battery 13.The other end ground connection of coil 34 or be connected with negative terminal 31.
As can be seen from Figure 2, the coil of magnetic switch 3 is made up of a sucking coil and a hold-in winding, the substantially equal and head end of the number of turn of two coils links together, the tail end of sucking coil 36 and the power end of direct current generator are also that the main contact output wiring terminal of magnetic switch is connected, the tail end bonding of hold-in winding 37.The resistance of sucking coil 36 is less, if voltage rating is the starter motor of 24V, its resistance is generally about 100 milliohms, such starter motor can little moment of torsion slow-speed before magnetic switch 3 main contact is closed, thus when allowing actuation gear 6 be against on flywheel ring gear 10 end face, actuation gear 6 can slowly rotate, fork tooth butt condition, engaging-in engine flywheel gear ring 10; After engaging-in gear ring, magnetic switch 3 main contact just can close, and just has big current and flow through in motor 1, and starter motor just can export by high pulling torque, thus avoids the generation of starter motor mill teeth fault.Therefore this kind of starter motor is also referred to as soft engaging starter.
Because the sucking coil 36 of this kind of starter relay 3 and the head end of hold-in winding 37 connect together, in order to ensure the reliable power-off of magnetic switch 3, the sucking coil 36 of such magnetic switch 3 and the effective turn of hold-in winding 37 must be basically identical, and the number of turn of hold-in winding 37 can not very little, the number of turn of such sucking coil 36 is also more.Although the method for sucking coil 36 number of turn can be reduced by the wire diameter of suitable increase sucking coil 36, starter motor can slowly be rotated before magnetic switch 3 main contact is not closed; But it is too many that the number of turn of sucking coil 36 can not reduce, otherwise consider the reliable power-off of magnetic switch 3, the number of turn of hold-in winding 37 also needs significantly to reduce.The soft engagement moment produced due to this kind of starter motor is limited, in some cases, during as many in high/low temperature, discharged or defective battery, flywheel ring gear end face burr, inner generation wearing and tearing of starter motor etc., after energising, actuation gear exists cannot the phenomenon of engaging-in gear ring, there will be apical tooth situation, the sucking coil of magnetic switch is just forced to long-time by larger electric current, and magnetic switch easily occurs burning fault.Especially 12V starter motor, the soft engagement moment of starter motor is less, and apical tooth rate is higher, and the rate of fault that magnetic switch is burnt is higher.
In addition when after starter motor generation apical tooth, namely actuation gear 6 cannot engaging-in gear ring, and the contact of magnetic switch 3 cannot realize closing, and the sucking coil 36 of magnetic switch 3 still has big current to pass through, but electric current diminishes gradually, and namely starter motor produces soft engagement moment and diminishes.Electric current diminishes larger mainly due to the heat produced in coil electricity process, and along with the increase of time, the resistance of sucking coil 36 becomes gradually and causes greatly.Therefore when starter motor generation apical tooth cannot after engaging-in gear ring, if continue to allow sucking coil 36 pass through electric current, the concept realizing the engaging-in gear ring of actuation gear is zero substantially, magnetic switch can be caused on the contrary to cross heat affecting starter motor next time and successfully engage the overheated generation burning fault with magnetic switch sucking coil.

First embodiment
Consult Fig. 3, the structure of starter motor of the present utility model is roughly similar to the auxiliary meshing type starter structure shown in Fig. 1, still the relay 12 comprising motor 1, the magnetic switch 3 be connected with motor 1 and be connected with magnetic switch 3, relay 12 is still connected with key switch 35 by terminal 50c (terminal 50c also cries and controls power supply terminal), and key switch 35 is arranged on storage battery 13 and controls between power supply terminal 50c.Magnetic switch 3 is substantially identical with common auxiliary meshing type magnetic switch, still adopts pair of contact to control the big current break-make of motor 1, comprises sucking coil 36 and hold-in winding 37.Because main model utility point of the present utility model is relay, other detailed construction (can consult Fig. 1) same as the prior art of relevant starter motor, just to it does not do at this more and repeats, just describe in detail to the structure of relay below.
Relay 12 comprises input terminal 121, Out let 122, power tube Q1 and a protecting control module 123.Input terminal 121 is connected with the terminal 18 (terminal 18 is also magnetic switch power supply terminal) of magnetic switch 3.Out let 122 is connected with the head end of hold-in winding 37 and the head end of sucking coil 36, because the head end of hold-in winding 37 and the head end of sucking coil 36 are connected to terminal 50, so Out let 122 is connected with terminal 50.Power tube Q1 is connected between input terminal 121 and Out let 122.Protecting control module 123 is connected with power tube Q1, according to terminal voltage and/or pressure drop, the current"on"time of starter motor and/or initiatively engage number of times control power tube Q1 conducting/by.
In conjunction with consulting Fig. 4, protecting control module 123 is connected with control power supply terminal 50c by terminal 311, circuit 132, comprises voltage acquisition module 1231, voltage comparison module 1232, timing module 1233, counting module 1234 and control unit 1235.Voltage acquisition module 1231 is for gathering the terminal voltage of starter motor, voltage comparison module 1232 for by centralized procurement to terminal voltage compared with a setting voltage, timing module 1233 for detect starter motor current"on"time/ON time of power tube Q1, counting module 1234 carries out the number of times of initiatively engagement capability for adding up protecting control module, control unit 1235 and voltage comparison module 1232, timing module 1233, counting module 1234 connects respectively, and control unit 1235 is based on voltage comparison module 1232 and/or timing module 1233 and/or counting module 1234 conducting/by power tube Q1.In the present embodiment, voltage acquisition module 1231 comprises one first voltage acquisition module 12311, first voltage acquisition module 12311 is connected with the terminal 19 (terminal 19 is also the input terminal of motor) of motor 1 by terminal 312, voltage sense line 133, to detect the voltage of the input terminal 19 of magnetic switch 3, namely for judging whether the contact of magnetic switch closes, so that control unit 1235 interpretation is the need of carrying out starter motor initiatively engagement capability.
By said structure, the Out let 122 of relay 12 controls sucking coil 36 and the hold-in winding 37 of magnetic switch 3.Protecting control module 123 realizes the power on/off of two coil circuits of magnetic switch 3 by the conducting and cut-off controlling power tube Q1 (as metal-oxide-semiconductor).
After key switch 35 is energized; protecting control module 123 starts to detect voltage or pressure drop; when voltage or pressure drop do not meet the condition of magnetic switch 3 make contact, control unit 1235 controls starter motor and carries out active engagement capability, makes the smooth engaging-in gear ring of actuation gear.Which enhance the engagement success rate of driver's one push start, improve customer satisfaction, reduce the rate of fault that the magnetic switch sucking coil that causes due to starter motor apical tooth burns simultaneously.
Below in conjunction with the logic control flow process figure of the starter motor of Fig. 5 the utility model first embodiment, introduce the working procedure of starter motor in detail, as shown in the flowchart:
Key switch 35 (being also ignition key 35) is connected rear (step 100); the terminal 50c of relay obtains electric; power tube Q1 conducting, the timing module simultaneously in protecting control module starts timing, and the number of times that initiatively engages in counting module is set to 0.The output terminal of relay and the terminal 50 of magnetic switch obtain electric afterwards, in the sucking coil 36 that the electric current of the power supply terminal 18 of such magnetic switch flows to magnetic switch 3 by the Out let 122 of relay, the terminal 50 of magnetic switch and hold-in winding 37, actuation gear 6 is got towards flywheel ring gear 10 under magnetic switch produces the effect of electromagnetic force, equally because the resistance of the sucking coil 36 of magnetic switch is smaller, motor can drive the little moment of torsion of actuation gear to rotate, and actuation gear starts to carry out flexibility with flywheel ring gear and engages.
Starter motor is piloted engine in process; after the time T1 (general terminal 50c or power tube Q1 ON time substantially identical) of terminal 50c or power tube Q1 conducting setting; as T1 is set to 300ms, the first voltage acquisition module 12311 of protecting control module 123 gathers the voltage of the input terminal 19 of motor by voltage sense line 133.When the voltage of the input terminal 19 motor being detected does not meet the condition (voltage U 3 as the voltage≤setting of the input terminal 19 of motor) of magnetic switch make contact, then judge that magnetic switch contact is not closed, the power supply terminal 18 of magnetic switch and the non-conducting of input terminal 19 of motor, namely actuation gear does not realize engaging with flywheel ring gear, then control unit 1235 controls power tube Q1 and ends, counting module 1233 restarts timing, Out let 122 power-off of relay, terminal 50 power-off of magnetic switch, thus actuation gear is return automatically.Control unit 1235 judges initiatively engaging times N i and whether be less than or equal to setup parameter N (as 3 times) in counting module 1234, as control unit 1235 judges that initiatively engaging number of times is less than or equal to 3 times, the time T2 (as 50ms) then arriving setting deadline at power tube Q1 controls power tube Q1 conducting again afterwards, what simultaneously counting module 1234 recorded initiatively engage number of times increase by 1, namely allows Ni=Ni+1.Due to power tube Q1 conducting again, the Out let 122 of relay and the terminal 50 of magnetic switch again electric, same actuation gear, under the effect of magnetic switch electromagnetic attraction, is again got and is engaged with actuation gear, and little moment of torsion rotate.Getting due to each actuation gear can be different from the contact position of flywheel ring gear end face, and therefore the engagement success rate of this starter motor is the same with engaging success rate last time.If first time, the engagement success rate of starter motor was 90%, then after adopting 1 active engagement capability, the engagement success rate of starter motor is: 90%+ (1-90%) * 90%=99%.
Equally when after power tube Q1 ON time to the time T1 of setting, protecting control module 123 can detect Check point voltage or pressure drop equally again, to judge whether magnetic switch contact closes, if judge that magnetic switch contact is not sent out closed, control unit 1235 controls power tube Q1 again to be ended, Out let 122 power-off of relay, thus actuation gear is return automatically, and the times N judging initiatively to engage whether times N i be less than or equal to setting; If the times N that Ni > sets, control unit 1235 controls power tube Q1 and continues cut-off, and relay and starter motor quit work.If judge Ni still≤setting times N, again arrive the time T2 of setting deadline at power tube Q1 after, control unit 1235 just controls power tube Q1 conducting again (carrying out active engagement capability), the Out let 122 of relay and the terminal 50 of magnetic switch obtain electric, actuation gear is again got under the effect of magnetic switch electromagnetic attraction and engages with flywheel ring gear.So repeatedly, until it is closed to judge that magnetic switch contact occurs, namely actuation gear and engine flywheel gear ring realize engaging, and control unit 1235 just controls power tube Q1 and continues conducting, starter motor will continue starter motor, until engine start success or terminal 50c power-off.
So both can avoid the magnetic switch generation burning fault because starter motor generation apical tooth causes; turn improve the engagement success rate of starter motor one push start (the engagement success rate as common starter motor is 90% simultaneously; it is 3 times that protecting control module initiatively engages number of times, then the one push start engagement success rate of new solution is: 90%+ (1-90%) * 90%+ (1-(1-90%) * 90%) * 90%+ (1-(1-(1-90%) * 90%) * 90%) * 90%=99.99%.
Second embodiment
As described in Figure 6, the structure of the relay of the present embodiment is roughly the same with the structure of the relay of the first embodiment, difference is: first voltage acquisition module 12311 of the present embodiment is connected with terminal 18 by terminal 312, voltage sense line 134, to detect the voltage of the terminal 18 of magnetic switch 3, namely for judging whether the contact of magnetic switch closes, so that control unit 1235 interpretation is the need of carrying out starter motor initiatively engagement capability.In conjunction with consulting Fig. 4, the protecting control module 123 of the present embodiment comprises voltage acquisition module 1231, voltage comparison module 1232, timing module 1233, counting module 1234 and control unit 1235 equally.Voltage acquisition module 1231 is for gathering the voltage of the terminal 18 of magnetic switch, voltage comparison module 1232 compares for the voltage of the terminal 18 by the magnetic switch detected and setting voltage, timing module 1233 for detect starter motor current"on"time/ON time of power tube Q1, counting module 1234 carries out the number of times of initiatively engagement capability for adding up protecting control module, control unit 1235 and voltage comparison module 1232, timing module 1233, counting module 1234 connects respectively, and control unit 1235 is based on voltage comparison module 1232 and/or timing module 1233 and/or counting module 1234 conducting/not conducting/by power tube Q1.About other detailed construction of relay is identical with the first embodiment, just it does not done at this more and repeat.
