Abstract
The utility model discloses an electric fuel pump which relates to the technical field of automobile engines, in particular to an electric fuel pump for an engine. The electric fuel pump comprises a plastic rear cover and an armature component, wherein an end cover with a split structure and a brush holder are combined into an easily-assembled integrated end cover with an integrated structure, the high mould manufacture cost is saved, and the electric fuel pump not only satisfies the structural precision requirement, but also is easy to assemble; a rotor poking fork adopts the model design, and POM engineering material is arranged on the armature component by injection molding to enable the POM engineering material and the armature component to be combined into a whole so that the effects of high stability, good concentricity, easy control, easy assembly and the like are achieved; and the plastic rear cover mould is designed with a circular eccentric groove, and a filter screen is neatly clamped into the groove to play the roles of positioning and fixing.
Description
Technical field
The utility model relates to technical field of automobile engine, and feature relates to the electric fuel punp that motor is used.
Background technique
The electric fuel punp that existing motor car engine is used, its end cap is to separate independently with brush holder, cause assembly precision and poor stability, and die cost expense height, rotor does not adopt the integrated through injection molding structure, uses two difform shift forks mutually fork to be connected on the armature assembly axle, and filter screen is that the toroidal of random cutting is considered cloth, put into aluminium bonnet and plastic rear cover between the two without any processing, the location does not have spacing.
The model utility content
The purpose of this utility model is: design a kind of electric fuel punp, to overcome above defective, saved expensive Mold Making expense, assemble when satisfying the structure precision requirement and easily.
According to above-mentioned purpose, the technical solution of the utility model is: a kind of electric fuel punp, comprise plastic rear cover and armature assembly, it is characterized in that: described electric fuel punp is provided with the one end cap that the end cap of minute body structure and brush holder is combined as the integrative-structure of easy assembling.
Be injected with the armature shift fork that combines together with armature assembly on the described armature assembly.
Described armature shift fork is the POM engineering material.
Be provided with circular eccentric groove in the described plastic rear cover, in the eccentric groove of this circle the smooth filter screen that plays the positioning and fixing effect in this groove that snaps in be installed.
Compared with prior art, advantage of the present utility model and beneficial effect are:
1, the utility model product is adjusted into integrative-structure with the end cap of original minute body structure and brush holder redesign, has saved expensive Mold Making expense, when satisfying the structure precision requirement and easily assembling.
2, the utility model product, rotor shift fork adopt mold design, thereby use the POM engineering material to be injection-moulded in to make on the armature assembly both effects such as obtaining more stable, good concentricity easy assembling easy to control that combines together.
3, the utility model product is designed circular eccentric groove smooth the snapping in of filter screen played the positioning and fixing effect in the groove on the plastic rear cover mould.
Description of drawings
Fig. 1 is the example structure schematic representation of the utility model electric fuel punp.
In the drawings:
1, one end cap 2, armature shift fork 3, filter screen 4, aluminium bonnet
5, plastic rear cover 6, armature assembly.
Embodiment
In conjunction with the accompanying drawings 1, example structure schematic representation for the utility model electric fuel punp, this electric fuel punp, comprise one end cap 1, armature shift fork 2, filter screen 3, aluminium bonnet 4, plastic rear cover 5 and armature assembly 6, described one end cap 1 has replaced the end cap and the brush holder of original minute body structure, become the integrative-structure of easy assembling, be injected with the armature shift fork 2 that combines together with armature assembly 6 on the described armature assembly 6, between described armature assembly 6 and plastic rear cover 5, be aluminium bonnet 4, between aluminium bonnet 4 and plastic rear cover 5, be provided with filter screen 3, this filter screen 3 plays the positioning and fixing effect, entirely is entrapped in the circular eccentric groove in the plastic rear cover 5.
