Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
As shown in Fig. 1 ~ 4, a kind of automobile, motorcycle instrument stepper motor waterproof and dustproof structure, including base 1 and upper lid 2,
In cavity between described base 1 and upper lid 2, stator piece 5, gear train, two coils 3 and two corresponding iron cores are installed
19, described gear train comprises rotor wheel 6, breast wheel and output wheel 9, and described rotor wheel 6 drives output wheel 9, institute by breast wheel
The coil pin stating coil 3 two ends stretches out in outside lid 2 respectively, and the output shaft upper end of described output wheel 9 stretches out in outside lid 2,
It is provided between described output wheel 9 and base 1 and be sheathed on output shaft lower end to prevent the butterfly spring 10 of output wheel 9 shake, institute
State and be coated with one layer of table sealing compound 11 at the cooperation between the wheel hub of output wheel 9 and the positioning oil groove of upper lid 2.Due to butterfly bullet
Spring 10 is contained in output wheel 9 below so that output wheel 9 is subject to power upwards, the contact surface gapless of such output wheel 9 and upper lid 2,
By output wheel 9 and on lid 2 between cooperation at coat table sealing compound 11, reach waterproof and dustproof purpose, after preventing shipment
Because of water inlet, enter the defective products that dirt causes.
In the present embodiment, as shown in Fig. 2 the pin bores with upper lid 2 can be arranged with the coil pin 12 of described coil 3
The soft rubber stopper 13 of sealing cooperation is so as to all directions cooperation is interference, to reach waterproof and dustproof purpose；Or, as shown in figure 4,
Described coil pin 12 can be coated with table use with upper lid 2 interference fit at described upper lid 2 inner side and the cooperation of coil pin 12
Sealing compound 14, reaches waterproof and dustproof purpose.Match with coil pin 12 on described base 1 keep away a hole can be provided with order to
Form the glue position 15 of blind hole, keep away the axial location that a hole changes coil 3, reach waterproof and dustproof purpose.

To sealing purpose；Or, as shown in figure 4, ultrasonic wave glue position 17 can be provided with described base 1 and the cooperation of upper lid 2, by super
After upper lid 2 and base 1 are welded by sound wave plastic cement, to reach waterproof and dustproof purpose.
At present, get on the car in market, two coils 3 of motorcycle instrument stepper motor are assemblied in above stator piece 5, in order to keep away
Allow train, the distance between coil block increases, cause stator piece 5 width to increase, material usage increases, high cost.In addition, line
Circle 3, by the way of embedded coil rack, causes iron core 19 materials to increase, and coil 3 coiling difficulty height, efficiency are low, thus
Increase cost.
In the present embodiment, as shown in Figure 1 and 2, two iron cores 19 are symmetricly set in stator piece 5 lower section and close to each other, institute
State gear train to be arranged at stator piece 5 top and avoid the horizontal interference of two lateral coils 3.Due to coil 3 is assembled under stator piece 5
Face, reduces the axial location of coil 3 so that gear train can avoid the Axial Interference of coil 3, between two such coil 3
Distance can reduce, that is, in the case of not affecting performance, two coils 3 are close proximity to and then stator piece 5 reduces width therewith
Degree, reaches the effect of material-saving, reduces cost.
In the present embodiment, described iron core 19 adopts plug-in type iron core 4, and the coil holder of described coil 3 is provided with and plug-in type
The iron core hole that iron core 4 matches.As shown in figure 3, compared to existing embedded iron core 18, the plug-in type iron core 4 of the present invention has
Have the advantage that：First, plug-in type iron core 4 can reduce material usage, reduces cost effectiveness；Secondly, embedded iron core
18 must load plastic cement coil holder before coil 3 coiling, so bring inconvenience to coiling positioning, coiling clamping efficiency is relatively low, and inserts
Enter formula iron core 4 and can reinstall plastic cement coil holder after coiling, iron core 19 during coil 3 coiling, can not be loaded, permissible during coiling
Using the iron core hole positioning of plastic cement coil holder, coil holder easy clamping during coiling, and easily realize automatic charging, greatly improve coiling effect
Rate is it is also possible to reduce the effect of cost.
In the present embodiment, described rotor wheel 6 simultaneously near two coils 3 so that output torque increases, improve product
Reliability.Described breast wheel comprises intermeshing first breast wheel 7 and the second breast wheel 8, described rotor wheel 6 and further
One breast wheel 7 is meshed, and described output wheel 9 is meshed with the second breast wheel 8, described first breast wheel 7, the second breast wheel 8 and
Output wheel 9 avoids the Axial Interference of coil 3.
Coil 3 is assembled to below stator piece 5 for this automobile, motorcycle instrument stepper motor waterproof and dustproof structure, makes gear
System can avoid the Axial Interference of coil 3, and the distance between two such coil 3 can reduce, and stator piece reduces width therewith,
Reach material-saving, the effect of reduces cost.Simultaneously as coil 3 is near rotor wheel 6, output torque is made to increase；Iron core 19 is adopted
With plug-in type, it is possible to reduce material usage, reduce cost effectiveness.In addition, iron core 19 can not be loaded during coil 3 coiling,
Using the iron core hole positioning on coil holder, coil holder easy clamping during coiling, easily realize automatic charging, improve winding efficiency, also may be used
To reduce the effect of cost.
In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment same or similar partly mutually referring to.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple modifications to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can be realized without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
