Abstract
The invention provides an electrical seat, which is an integral structural part with the structural characteristics of a rear end cover and a brush basin of a motor. A plurality of groups of inner mounting supports, a plurality of outer mounting supports and a bearing chamber are arranged on the inner lateral surface of the electrical seat. Each inner mounting support comprises two cylinders which are arranged at an interval. The structures of the two cylinders are symmetrical and the same. A groove is formed on each cylinder, and the trend of the groove is parallel to the diameter of the electrical seat. A platform is arranged on the inner side of each cylinder adjacent to the edge of a corresponding groove. An undercut is arranged on the inner side of each cylinder adjacent to the edge of a corresponding platform. The groove, the platform and the undercut are sequentially and adjacently arranged. The planes of the platforms are flush with the bottom surfaces of the grooves. The undercuts are higher than the platforms. An interval for accommodating a sliding rail is formed between each undercut and a corresponding platform. The groove, the platform and the undercut are form an 'L'-shaped mounting position for positioning the inner end of the sliding rail. The electrical seat has the advantages of a few parts, material saving, low noise and high reliability.
Description
Technical field
The present invention relates to a kind of motor component, relate 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, and installs separately, and the brush basin generally adopts plastics and/or metal material to make, and installs separately separately.Such electric seat when making, needs respectively die sinking moulding owing to be comprised of two different 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 type 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 again the weight of motor.
Summary of the invention
Purpose of the present invention 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 present invention has adopted following technical scheme: a kind of electric seat, it is an integral structure component with rear end cover structure feature and brush basin architectural feature of motor, its medial surface is provided with interior installation foot and a plurality of outer installation foot for fixed rack outer end and location stage clip that many groups are used for fixed rack the inner, and for bearings mounted bearing chamber, be characterized in, described interior installation foot comprises the cylinder that two intervals arrange, the symmetrical configuration of two cylinders is identical, the line of centres of two cylinders is perpendicular to the diameter of electric seat, cylinder is provided with a groove that trend is parallel with the diameter of electric seat, the above-mentioned recess edge of the inboard next-door neighbour of cylinder is provided with a platform, the above-mentioned platform edges of the inboard next-door neighbour of cylinder is provided with a back-off, groove, platform, back-off sequentially is close to arrangement, and the plane of platform is concordant with the bottom surface of groove, the height of back-off is higher than platform, be provided with the interval for accommodating slide rail between back-off and the platform, groove, platform and back-off are common to form one for " L " type installation position of positioning slide the inner; Described slide rail the inner is provided with the barb-shaped structure adaptive with 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.
Electric seat of the present invention has been owing to adopted above technical scheme, has that number of components is few, material is economized, noise is low, the advantage of good reliability.
Description of drawings
Fig. 1 is the perspective view of electric seat of the present invention;
Fig. 2 is the structural representation of interior installation foot;
Fig. 3 is the structural representation of interior installation foot;
Fig. 4 is the structural representation with the supporting slide rail of the present invention.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, electric seat of the present invention, it is an integral structure component with rear end cover structure feature and brush basin architectural feature of motor, its medial surface be provided with many groups be used for fixed rack the inner interior installation foot 1 and a plurality of for fixed rack outer end and location stage clip outer installation foot 2 and be used for bearings mounted bearing chamber 3, and positioning pillars 4 and plug 5.
Referring to Fig. 2, interior installation foot 1 among the present invention comprises the cylinder that two intervals arrange, the symmetrical configuration of two cylinders is identical, the line of centres of two cylinders is perpendicular to the diameter of electric seat, cylinder is provided with a groove 11 that trend is parallel with the diameter of electric seat, the above-mentioned recess edge of the inboard next-door neighbour of cylinder is provided with a platform 12, the above-mentioned platform edges of the inboard next-door neighbour of cylinder is provided with a back-off 13, 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, be provided with the interval for accommodating slide rail between back-off 13 and the platform 12, groove 11, " L " type installation position that is used for positioning slide the inner of platform 12 and back-off 13 common formation.
Referring to Fig. 4, be provided with the barb-shaped structure 61 adaptive with above-mentioned " L " type installation position with matching used slide rail 6 the inners among the present invention.
Referring to Fig. 3, with the present invention 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 among the present invention is owing to designed " L " type installation position of positioning slide the inner, can limit the degree of freedom of metal sliding rail, the associated jitter of the carbon brush that control cooperates with slide rail is optimized machinery noise and the electromagnetic noise problem that is caused by the carbon brush shake thereby reach.
Matching used slide rail can effectively hook brush basin end cap, further limit the degree of freedom of slide rail, improve reliability, and alternative traditional brush holder 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, the metal connecting sheet that can not only the registration calculation Design goes out can also increase by a step solder joint technique behind the assembly connection sheet, brace is fixed on the end cap, has technique simple, the advantage of economical with materials.
