End is arranged on the side opening inner side of dynamic iron core, and the other end is pierced by shell, is axially offered in the middle part of another side end face of dynamic iron core
One section of cone tank offers cylindrical groove along cone tank at the end of the axial, and dynamic iron core outer wall opens up multiple air discharge ducts, air discharge duct in an axial direction
Interior filling damping grease.
Further, copper sheathing is the cylindrical shell structure of both ends open to lengthen casing.
Further, damper is equipped in cylindrical groove.
Further, air discharge duct is equipped with 3.
Further, static iron core is close to the tapered core in the side of dynamic iron core, along close to dynamic iron core direction gradually by
Thick attenuate extends to form.
Further, shell includes yoke and the cover board with being assemblied on yoke.
The utility model has the advantages that：
The novel automobile electromagnetic switch of the utility model is attracted, release time stablizes, and switch motion is stablized, and ensure that assembling
After scrape and catching phenomenon will not occur, moreover it is possible to reach apparent Noise Reduction, meet making in automobile industry high standard
Use condition.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of novel automobile electromagnetic switch provided by the utility model；
Fig. 2 is the structure diagram of dynamic iron core provided by the utility model.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Such as Fig. 1 and Fig. 2, the novel automobile electromagnetic switch of the utility model, including shell 1, the line being set in shell 1
Coil 2, the enameled wire 21 being wound on bobbin 2 and the static iron core 3 being installed in bobbin 2 and pull rod component.
Bobbin 2 is detachably set in shell 1, and stage casing is tubular structure, and inside sets a copper sheathing 5, set in copper sheathing 5
Spring 6,6 one end connecting rod component of spring are equipped with, the other end is set on static iron core 3.
Pull rod component includes pull rod 7 and dynamic iron core 4, and dynamic iron core 4 is the hollow cylinder of both ends open, and 7 one end of pull rod is set
The side opening inner side in dynamic iron core 4 is put, the other end is pierced by shell 1, axially one is offered in the middle part of another side end face of dynamic iron core 4
Section cone tank 41, offers cylindrical groove 42,4 outer wall of dynamic iron core opens up multiple air discharge ducts in an axial direction along 41 at the end of the axial of cone tank
43, air discharge duct 43 is equipped with 3, and damping grease is filled in air discharge duct 43, convenient for making with the grease cooperation for being sprayed on 4 surface of dynamic iron core
With.
Copper sheathing 5 is the cylindrical shell structure of both ends open, static iron core 3, spring 6 and dynamic iron core 4 are respectively provided with to lengthen casing
In in copper sheathing 5, good guiding role is played using copper sheathing 5, it is not in scrape to further ensure after solenoid valve assembles
And catching phenomenon.
