In this case, because motor 4 not being energized, so being not accompanied by the little of the rotary driving force of motor 4 When little gear 7 side end face of the ring gear 8 in ring gear 8 side end face of gear 7 and rotation stopping is collided, little gear 7 is not Ring gear 8 can be engaged to, but by the second solenoid 18 being energized after certain preset time, thus movable ferrum Core 15 makes while driving spring 10 flexure to secured core 16 side shifting, thus engine starter motor 1 contact (12, 13,14) becoming closed circuit, the rotary driving force of motor 4 passes to little gear 7, and little gear 7 rotates, thus little gear 7 rotates Engage with ring gear 8 to the position that can be engaged to ring gear 8, make electromotor restart.On the other hand, to When one solenoid 17 is energized and is released to ring gear 8 side by little gear 7, little gear 7 is at the spiral shell being formed on output shaft Slide on Flos Calystegiae sepii key and when axial annular gear 8 side shifting, owing to little gear 7 can rotate corresponding to the angle of helical spline Angle, therefore when the collision of little gear 7 side end face of ring gear 8 side end face of little gear 7 and ring gear 8, there is also The situation of ring gear 8 can be engaged to swimmingly owing to little gear 7 has carried out some rotations.According to experiment, only first In the case of solenoid 17 energising, little gear 7 is engaged to ring gear 8 rear engine swimmingly and starts the contact of motor 1 Situation that (12,13,14) can be started by closed circuit thus electromotor and ring gear 8 side end face of little gear 7 and ring gear The situation that little gear 7 side end face of 8 is collided and can not be engaged compares, and the ratio of the former with the latter is of about 50% to 50%.

Only the first solenoid 17 will be energized before the second solenoid 18 being energized after certain preset time Stage little gear 7 engage with ring gear 8 swimmingly after, the contact (12,13,14) of engine starter motor 1 becomes and closes Road and start the situation of electromotor and be set to the former, the first solenoid 17 will be energized and little gear 7 the most swimmingly with annular Gear 8 engages, and is being energized the second solenoid 18 thus the contact of engine starter motor 1 after certain preset time (12,13,14) become closed circuit and start the situation of electromotor and be set to middle person, and will be to the first solenoid 17 and the second electromagnetic wire Circle 18 carries out being energized simultaneously and starts the situation of electromotor when being set to the latter, rushes when little gear 7 is engaged to ring gear 8 During power of hitting compares with collision sound, the former is because engine starter motor 1 is engaged institute before energising starts swimmingly Smaller with impulsive force and collision sound, for middle person, to ring gear 8 side end face and ring gear 8 little of when young gear 7 Impact force and collision sound during the collision of gear 7 side end face can produce, therefore when only to the first solenoid 17 energising With engage swimmingly the former compared with and become bigger impulsive force and collision sound, but with to the first solenoid 17 and the second electricity Magnetic coil 18 is energized simultaneously, the attraction that the captivation produced by the first solenoid 17 is produced with the second solenoid 18 The making a concerted effort of power attract movable core, via the little gear 7 of connecting rod 9 translational speed to axial annular gear 8 side more than other The latter of situation compares, and becomes slight impulsive force and magnetic hits sound.

It addition, in the former case, the first solenoid 17 is energized thus little gear 7 is engaged to ring swimmingly Shape gear 8, and by the movable core 15 movement to secured core 16 side, the contact of engine starter motor 1 (12,13, 14) become closed circuit after, the second solenoid 18 is energized, but even if the second solenoid 18 is energized, Because the contact of engine starter motor 1 (12,13,14) has had become as closed circuit, so not producing by the second solenoid 18 produce captivations cause impulsive force, collision sound.

Effect as embodiment 5, using the teaching of the invention it is possible to provide a kind of following engine starter motor device: use and utilize a pair Movable core 15 and secured core 16 have possessed the ejecting mechanism of little gear 7 and docking point (12,13,14) carries out the mechanism of opening and closing Existing known magnetic switch structure while, by carrying out the first solenoid and the channel electric controlled of the second solenoid System, thus completely stop after electromotor restart or common electromotor plays disorder of internal organs, the most only to the first electromagnetism Coil 17 is energized, and is being energized the second solenoid 18 after certain preset time, and to the second solenoid In the stage being energized the first solenoid 17 before 18 energisings, with the probability of about 50%, little gear 7 engages swimmingly To ring gear 8, so producing when little gear 7 side end face of ring gear 8 side end face of little gear 7 and ring gear 8 is collided Impulsive force, collision sound smaller, therefore, it is possible to improve mute, reliability and durability, and inexpensively.

In embodiment 10, describe when electromotor stopped completely when restarting or generally start, The uncurbed electric current that is energized solenoid 40 is so that the electromotor situation restarting or start, and in the 11st embodiment In, it is an example of following situation: restarting or not being after the idle stop rear engine of electromotor is stopped completely After idle stop restart but when vehicle brings into operation, driver is started by Key operation etc. and stopped rotation completely Usual starting in the sense that electromotor, determines via the confined electric current of resistive element 37 relative to being energized solenoid 40 Time, be energized after certain preset time uncurbed electric current to solenoid 40, makes electromotor restart or generally rises Dynamic.

After the idle stop rear engine of electromotor stops completely, producing brake release based on driver etc. Electromotor restart request, and when the time point having possessed the condition restarting electromotor makes electromotor restart, or work as Carry out when vehicle brings into operation that driver starts in the sense that the electromotor that stopped rotation completely by Key operation etc. is usual During starting, relay 38 is made to work based on the instruction from ECU by carrying out the instruction of self-control device 34, thus solenoid 40 are excited by the confined current electrifying via resistive element 37, and secured core 16 is magnetized thus by movable core 15 Attract to secured core 16 side, via connecting rod 9, little gear 7 is released to ring gear 8 side that stopped rotation.

In this case, because motor 4 not being energized, so being not accompanied by the little of the rotary driving force of motor 4 When little gear 7 side end face of the ring gear 8 in ring gear 8 side end face of gear 7 and rotation stopping is collided, little gear 7 is not Ring gear 8 can be engaged to, but make relay 39 by carrying out the instruction of self-control device 34 after certain preset time, by This solenoid 40 is excited by uncurbed current electrifying, movable core 15 make driving spring 10 flexure while to Secured core 16 side shifting being magnetized, thus the contact (12,13,14) of engine starter motor 1 becomes closed circuit, motor 4 Rotary driving force pass to little gear 7 and make little gear 7 rotate, thus little gear 7 rotates to be engaged to ring gear 8 Position and engage with ring gear 8, make electromotor restart.On the other hand, by solenoid 40 is energized via electricity The confined electric current of resistance body and make movable core 15 to secured core 16 side shifting being magnetized, when by little gear 7 to annular tooth When taking turns 8 sides release, slide on the helical spline being formed on output shaft to axial annular gear 8 side shifting at little gear 7 Time, because little gear 7 can rotate angle corresponding with the angle of helical spline, so at ring gear 8 side of little gear 7 During the little gear 7 side end face collision of face and ring gear 8, there is also due to little gear 7 carried out some rotate and can be smooth and easy Be engaged to the situation of ring gear 8.According to experiment, in the case of the only first solenoid 17 energising, little gear 7 is swimmingly Be engaged to ring gear 8 rear engine start motor 1 contact (12,13,14) by closed circuit thus what electromotor can start Situation, collides with little gear 7 side end face of ring gear 8 with ring gear 8 side end face of little gear 7 and situation about can not engage Comparing, the ratio of the former with the latter is of about 50% to 50%.

Will be before the uncurbed electric current that after certain preset time, solenoid 40 is energized, to solenoid 40 Be energized stage of confined electric current, after little gear 7 engages with ring gear 8 swimmingly, engine starter motor 1 Contact (12,13,14) becomes closed circuit and starts the situation of electromotor and be set to the former, and will be energized confined electricity to solenoid 40 Stream and little gear 7 do not engage with ring gear 8 swimmingly, after certain preset time, solenoid 40 is energized not by The electric current that limits thus the contact of engine starter motor 1 (12,13,14) become closed circuit and start the situation of electromotor and be set to Middle person, by initially solenoid 40 is energized uncurbed electric current to the situation starting electromotor be set to the latter time, to little During impulsive force when gear 7 is engaged to ring gear 8 and collision sound compare, the former is because engine starter motor 1 exists Energising is engaged so impulsive force and collision sound are smaller, for middle person, to the annular of when young gear 7 before starting swimmingly Impact force and collision sound when gear 8 side end face and the little gear 7 side end face collision of ring gear 8 can be logical to solenoid 40 Produce under the electricity state of confined electric current, thus with engage swimmingly the former compared with and become bigger impulsive force and touch Hit sound, but with due to the uncurbed electric current that is initially energized solenoid 40, therefore movable core is produced by solenoid 40 Raw maximum captivation attracts, via the little gear 7 of connecting rod 9 translational speed to axial annular gear 8 side more than other feelings The latter of condition compares, and becomes slight impulsive force and collision sound.

It addition, in the former case, the first solenoid 17 is energized confined electric current thus little gear 7 swimmingly It is engaged to ring gear 8, and by the movable core 15 movement to secured core 16 side, connecing of engine starter motor 1 Point (12,13,14) become closed circuit after, be energized uncurbed electric current to solenoid 40, even if to solenoid 40 Be energized uncurbed electric current, because the contact of engine starter motor 1 (12,13,14) has had become as closed circuit, so also Will not produce because energising has the impulsive force adding captivation produced by solenoid during uncurbed electric current and cause, touches Hit sound.

Effect as embodiment 11, using the teaching of the invention it is possible to provide a kind of following engine starter motor device: use and utilize one Movable core 15 and secured core 16 are possessed the ejecting mechanism of little gear 7 and docking point (12,13,14) has carried out the machine of opening and closing While the existing known magnetic switch structure of structure, by solenoid 40 being carried out the control that is energized, thus stopping completely Electromotor afterwards restart or common electromotor plays disorder of internal organs, be energized confined electric current to solenoid 40, and Be energized after certain preset time uncurbed electric current to solenoid 40, but is being energized uncurbed to solenoid 40 In the stage of the confined electric current that is energized solenoid 40 before electric current, the little gear of probability 7 with about 50% is nibbled swimmingly Close ring gear 8, so producing when little gear 7 side end face of ring gear 8 side end face of little gear 7 and ring gear 8 is collided Raw impulsive force, collision sound are smaller, therefore, it is possible to improve mute, reliability and durability, and inexpensively.
