Abstract

The utility model provides an electric base, which is an integral structure piece having the rear end cover structure characteristics of a motor and the brush base structure characteristics; a plurality of groups of internal installing feet, a plurality of external installing feet and a bearing chamber are arranged on the inner side plane of the electric base, wherein the internal installing feet comprise two columns in interval arrangement; the structures of the two column bodies are in symmetry and are the same; a groove which is parallel to the diameter of the electric base is arranged on the column bodies; a platform is arranged at the inner sides of the column bodies, close to edge of the groove; an inverted buckle is arranged at the inner side of the column body, close to the edge of the platform; the groove, the platform and the inverted buckle are adjacently arranged in sequence; the plane of the platform is level with the bottom surface of the groove; the inverted buckle is higher than the platform; an interval for accommodating a slide track is arranged between the inverted buckle and the platform; and an L-shaped installing position for positioning the inner end of the slide track is formed by the groove, the platform and the inverted buckle together. The electric base provided by the utility model has the advantages of fewer parts, saved materials, low noise and good reliability.

Description

Electric seat

Technical field

The utility model relates to a kind of motor component, relates in particular to a kind of electric seat.

Background technology

The electric seat of general motor comprises rear end cap and brush basin, and rear end cap generally adopts metal material to make, independent installation, and the brush basin generally adopts plastics and/or metal material to make, separately independent installation.Electric seat like this when making, needs die sinking moulding respectively owing to be made up of two various parts; When mounted, need again to install respectively, waste time and energy, cost is high; And taken more motor axial dimension and space, hinder miniaturization, the thin typeization of motor.In addition, because the rear end cap of making separately generally adopts metal material to make, weight is heavier, has both consumed metal material, has increased the weight of the weight of motor again.

The utility model content

The purpose of the utility model exactly in order to address the above problem, provides a kind of electric seat with new structure.

In order to achieve the above object; The utility model has adopted following technical scheme: a kind of electric seat is an integral structure component with rear end cap architectural feature with brush basin architectural feature of motor, and its medial surface is provided with many groups and is used for fixing the inner interior installation foot of slide rail and a plurality ofly is used for fixing the outer installation foot of slide rail outer end and location stage clip and is used for bearings mounted bearing chamber; Be characterized in; Installation foot comprises two cylinders that are provided with at interval in described, and the symmetrical configuration of two cylinders is identical, and the line of centres of two cylinders is perpendicular to the diameter of electric seat; Cylinder is provided with the parallel groove of diameter of a trend and electric seat; The above-mentioned recess edge of the inboard next-door neighbour of cylinder is provided with a platform, and the above-mentioned platform edges of the inboard next-door neighbour of cylinder is provided with a back-off, and groove, platform, back-off are close to arrangement in proper order; And the plane of platform is concordant with the bottom surface of groove; The height of back-off is higher than platform, is provided with the interval that is used for ccontaining slide rail between back-off and the platform, and one of the common formation of groove, platform and back-off is used for inner " L " type installation position of positioning slide; Described slide rail the inner is provided with and the adaptive barb-shaped structure in above-mentioned " L " type installation position.

Described outer installation foot is the integral installation post that top is " mountain " font, comprises two U-lags, and the cylinder outside between two U-lags is provided with back-off.

The electric seat of the utility model has been owing to adopted above technical scheme, has that part count is few, material is economized, noise is low, the advantage of good reliability.

Embodiment

Referring to Fig. 1, Fig. 2, Fig. 3; The electric seat of the utility model; It is a integral structure component with rear end cap architectural feature with brush basin architectural feature of motor; Its medial surface is provided with the interior installation feet 1 that are used for fixing slide rail the inner of organizing more and is used for fixing the outer installation foot 2 of slide rail outer end and location stage clip and is used for bearings mounted bearing chamber 3 with a plurality of, and positioning pillars 4 and plug 5.

Referring to Fig. 2; Interior installation foot 1 in the utility model comprises two cylinders that are provided with at interval, and the symmetrical configuration of two cylinders is identical, and the line of centres of two cylinders is perpendicular to the diameter of electric seat; Cylinder is provided with the parallel groove 11 of diameter of a trend and electric seat; The above-mentioned recess edge of the inboard next-door neighbour of cylinder is provided with a platform 12, and the above-mentioned platform edges of the inboard next-door neighbour of cylinder is provided with a back-off 13, and groove 11, platform 12, back-off 13 order next-door neighbours arrange; And the plane of platform 12 is concordant with the bottom surface of groove 11; The height of back-off 13 is higher than platform 12, is provided with the interval that is used for ccontaining slide rail between back-off 13 and the platform 12, and groove 11, platform 12 are used for inner " L " type installation position of positioning slide with back-off 13 one of common formation.

Referring to Fig. 4, be provided with and the adaptive barb-shaped structure 61 in above-mentioned " L " type installation position with matching used slide rail 6 the inners in the utility model.

Referring to Fig. 3, with the utility model China and foreign countries installation foot 2 are integral installation posts that top is " mountain " font, comprise that two cylinders outsides between U-lag 21, two U-lags are provided with back-off 22.

Interior installation foot in the utility model is owing to designed inner " L " type installation position of positioning slide; Can limit the degree of freedom of metal slide rail; The associated jitter of the carbon brush that control cooperates with slide rail, thus reach machinery noise and the electromagnetic noise problem that optimization is caused by the carbon brush shake.

Matching used slide rail can effectively hook brush basin end cap; Further the degree of freedom of restriction slide rail improves reliability, and substitutes traditional brush carrier structure; Carbon brush can be dispelled the heat preferably; And the accumulation of the carbon dust that drops when being not easy to cause the carbon brush friction, and reduce the carbon brush that change in volume that metalwork causes because of corrosion causes and stop up, copper material saved.

Positioning pillars can not only be located the metal connecting sheet that accurate Calculation is designed, and can also behind the assembling brace, increase by a step solder joint technology, and brace is fixed on the end cap, has technology simple, the advantage of economical with materials.
