The integral type movable iron core structure of the electromagnetic switch for the novel energy car is stable in working, and long in service life, and initial failure phenomenon can not occur.
Description
Technical field:
The present invention relates to electromagnetic switch technical field, the integral type more specifically to a kind of new-energy automobile electromagnetic switch moves core structure.
Background technology:
Dynamic iron core is the actuator of electromagnetic switch of automobile starter, the electromagnetic force that electromagnetic switch winding produces makes iron core move, the contact promoting electromagnetic switch is moved, electric current is provided to vehicle starter, current overall formula moves iron core push rod riveting and lateral pin riveting two kinds of structures, and the integral type of push rod rivet pressing structure is moved iron core and movable contact spring can be caused to be suspended in switch enclosure, during high vehicle speeds, the impact switch box wall that movable contact spring swings becomes groove, causes electromagnetic switch early failure; The integral type of lateral pin structure moves iron core, and lateral pin riveting end likely destroys electromagnetic switch magnetic shield surface, causes dynamic iron core to move difficulty and early failure.
Summary of the invention:
Object of the present invention provides a kind of integral type of new-energy automobile electromagnetic switch to move core structure with regard to being, its action is more stable, failure phenomenon can not occur, and its useful life also more lengthens.
For achieving the above object, the integral type of a kind of new-energy automobile electromagnetic switch of the present invention is moved core structure and is comprised dynamic iron core, push rod and pull bar, described push rod and pull bar are ladder shaft-like structure, iron core forms center ladder hole, the inwall of center ladder hole forms embedding indent, the stub end of pull bar matches with the large nose end of center ladder hole, the stub end of push rod matches with the small bore end of center ladder hole, dividing plate is placed in embedding indent and between push rod and pull bar, engage spring sleeve is on pull bar, end cap and iron core fix and sleeve on pull bar.
Preferred as technique scheme, described iron core forms draw-in groove, and end cap is fixed in draw-in groove.
Beneficial effect of the present invention is: the present invention works more stable under the effect of coiling group, failure phenomenon can not occur, and it also extends the useful life of electromagnetic switch.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is described further:

In figure: 1, pull bar; 2, end cap; 3, iron core; 4, push rod; 5, dividing plate; 6, engage spring 11, center ladder hole; 12, embedding indent; 13, draw-in groove.
Embodiment:
See shown in Fig. 1 to 4: the integral type of a kind of new-energy automobile electromagnetic switch of the present invention is moved core structure and comprised dynamic iron core 3, push rod 4 and pull bar 1, described push rod 4 and pull bar 1 are ladder shaft-like structure, iron core 3 forms center ladder hole 11, the inwall of center ladder hole 11 forms embedding indent 12, the stub end of pull bar 1 matches with the large nose end of center ladder hole 11, the stub end of push rod 4 matches with the small bore end of center ladder hole 11, dividing plate 5 is placed in embedding indent 12 and between push rod 4 and pull bar 1, engage spring 6 sleeve is on pull bar 1, end cap 2 with iron core 3 fixing and sleeve on pull bar 1.
Described iron core 3 forms draw-in groove 13, and end cap 2 is fixed in draw-in groove 13.
Present invention employs iris type structure, namely as shown in Figure 1, dividing plate 5 is provided with between pull bar 1 and push rod 4, under the action of a magnetic force, iron core 3 passes through dividing plate 5 active force in pull bar 1 and push rod 4, thus drives pull bar 1 and push rod 4, thus drive whole electromagnetic switch to move to contact, the invention enables the stressed more even, therefore also more stable in whole course of action of pull bar 1 and push rod 4, situation about losing efficacy can not occur.
The foregoing is only and embody the preferred embodiment of the principle of the invention, therefore do not limit protection scope of the present invention, every equalization change done according to the present invention all belongs within the scope of the claims that the present invention contains with modifying.
