Abstract

The utility model discloses an integral movable iron core structure of an electromagnetic switch for a new energy automobile. The integral movable iron core structure comprises a movable iron core (3), a pushing rod (4) and a pulling rod (1). The pushing rod (4) and the pulling rod (1) are of stepped-shaft-shaped structures, a central stepped through hole (11) is formed on the movable iron core (3), an embedding groove (12) is formed on an inner wall of the central stepped through hole (11), the large-head end of the pulling rod (1) is matched with the large-hole end of the central stepped through hole (11), the large-head end of the pushing rod (4) is matched with the small-hole end of the central stepped through hole (11), a partition plate (5) is arranged in the embedding groove (12) and located between the pushing rod (4) and the pulling rod (1), a meshing spring (6) is inserted and sleeved on the pulling rod (1), and an end cover (2) and the iron core (3) are fixed and inserted on the pulling rod (1). The integral movable iron core structure is stable in work, an early failure phenomenon does not occur, and the service life of the integral movable iron core structure is prolonged.

Description

A kind of new-energy automobile moves core structure with the integral type of electromagnetic switch

Technical field:

The utility model relates to the electromagnetic switch technical field, moves core structure more specifically to a kind of new-energy automobile with the integral type of electromagnetic switch.

Background technology:

Moving iron core is the actuator of electromagnetic switch of automobile starter, the electromagnetic force that the electromagnetic switch winding produces moves iron core, move the contact that promotes electromagnetic switch, provide electric current to vehicle starter, the moving iron core of current integral type has push rod riveting and two kinds of structures of lateral pin riveting, and the moving iron core of the integral type of push rod rivet pressing structure can cause movable contact spring 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 is moved iron core, and it is surperficial that lateral pin riveting end might destroy the electromagnetic switch magnetic shield, causes moving iron core to move difficulty and early failure.

The utility model content:

The purpose of this utility model just is to provide a kind of new-energy automobile to move core structure with the integral type of electromagnetic switch, and its action is more stable, failure phenomenon can not occur, and also more lengthen its useful life.

for achieving the above object, a kind of new-energy automobile of the present utility model comprises moving iron core with the moving core structure of the integral type of electromagnetic switch, push rod and pull bar, described push rod and pull bar are multidiameter shape structure, form the center ladder hole on iron core, form the embedding indent on the inwall of center ladder hole, 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 the embedding indent and between push rod and pull bar, the engage spring sleeve is on pull bar, end cap and iron core fix and sleeve on pull bar.

Preferred as technique scheme forms draw-in groove on described iron core, and end cap is fixed in draw-in groove.

The beneficial effects of the utility model are: the utility model is more stable work under the effect of coiling group, failure phenomenon can not occur, and it has also extended the useful life of electromagnetic switch.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is structural representation of the present utility model

Fig. 2 is the structural representation of iron core

Fig. 3 is the structural representation of pull bar

Fig. 4 is the structural representation of push rod

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: a kind of new-energy automobile of the present utility model comprises moving iron core 3 with the moving core structure of the integral type of electromagnetic switch, push rod 4 and pull bar 1, described push rod 4 and pull bar 1 are multidiameter shape structure, form center ladder hole 11 on iron core 3, form embedding indent 12 on the inwall of center ladder hole 11, 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 sleeves are on pull bar 1, end cap 2 with iron core 3 fixing and sleeve on pull bar 1.

Form draw-in groove 13 on described iron core 3, end cap 2 is fixed in draw-in groove 13.

The utility model has adopted the iris type structure, namely as shown in Figure 1, be provided with dividing plate 5 between pull bar 1 and push rod 4, under the effect of magnetic field force, iron core 3 passes through dividing plate 5 active forces in pull bar 1 and push rod 4, thereby drives pull bar 1 and push rod 4, thereby driving whole electromagnetic switch moves to the contact, the utility model makes the stressed more even of pull bar 1 and push rod 4, and is therefore also more stable in whole course of action, the situation that can not lose efficacy.

Therefore the above only for embodying the preferred embodiment of the utility model principle, do not limit protection range of the present utility model, every equalization of doing according to the utility model change with modify all belong to the scope of the claims that the utility model contains within.
