Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 5, a kind of motor brush rocker plate assembly, comprise the brush rack plate pedestal 1 of bottom, the circular hole that brush rack plate pedestal center is motor output end, the both sides of circular hole are provided with two brush rooms 2, brush is provided with the brush 3 that can slide and the back-moving spring 4 in order to keep brush and motor output end to fit within doors, middle back-moving spring of the present utility model is disc spring, disc spring in mechanical field also referred to as plane scroll spring, have another name called clockwork spring, its one end is fixed and other end effect has moment of torsion, be out of shape in the torsional interaction lower spring material production elasticity of flexure, make spring planar produce torsion, in the utility model, this plane scroll spring is improved, an original scrollwork is divided into two and spirals 41, in the middle of two heads that spiral, it is U-shaped shell fragment 42, brush 3 end faces prop up the medial surface of U-shaped shell fragment, specifically can be shown in Figure 2, in figure, solid line is depicted as the initial condition that disc spring does not stress, dotted portion is the disc spring schematic diagram that direction extends of turning right after stressed, U-shaped shell fragment zone line just mates the profile of brush, both fitting tights, gap is easily controlled, disc spring and the motion of brush basic synchronization when brush moves, precision is good, and disc spring steel disc used is with respect to traditional stage clip, the spring steel wire reset effect such as torsion spring are better, working life is longer, preferably, in the middle of U-shaped shell fragment, be provided with bending wedge angle 421, bending wedge angle allows can better fit two sides of brush, two sides of U-shaped shell fragment, after preventing the long-time running of U-shaped shell fragment, generation deformation makes both sides angle become large.
As shown in Figures 3 and 4, on described brush room 2, two sides are provided with the spacing breach 21 of disc spring, the width of spacing breach is more bigger than the width of disc spring steel disc, spacing breach is the oblique disc spring positive stop strip 22 that is provided with outward, two heads that spiral of described disc spring are placed in brush room mouth, brush 3 is placed in the middle of U-shaped shell fragment, and insert in the lump brush within doors with U-shaped shell fragment, the advantage of oblique design is to make the head that spirals on both sides all to gather to the inside, in long-time use procedure, can there is oneself to clamp, the effect of self-recovery, also be to increase a disc spring design key point in useful life itself, in order further to strengthen the limit function of brush room to disc spring, be provided with the groove 23 connecting before and after U-shaped shell fragment for holding at the medial surface in brush room, in groove, can hold the both sides steel disc of U-shaped shell fragment, make it freely elastic in groove, but upper and lower displacement degree be subject to the spacing of groove, in order to facilitate wire to be connected with brush, the end face in brush room is provided with the wire casing 24 passing for wire.
As shown in Figure 5, brush 3 is provided with positioning U type shell fragment disc spring draw-in groove 31 from the distal face of motor output end, the width of disc spring draw-in groove is consistent with the width of U-shaped shell fragment, quality of fit between disc spring and brush is strengthened, this is that traditional stage clip or torsion spring all cannot be realized, limited location breach 21 and groove 23 when brushing room coordinate with disc spring in the utility model, while cooperation between brush and disc spring, there is disc spring draw-in groove 31, make like this quality of fit of brushing between room and brush also promote, naturally strengthened the quality of fit between three, quality of fit height, also can increase its useful life thereupon.
In Fig. 6, be on brush rack plate wherein a side schematic diagram of brush, disc spring is not installed, in figure, known described brush rack plate pedestal is provided with standoff 5, standoff bottom and the wire clip 51 that brush rack plate pedestal is fixed, upper end is provided with B word shape, the wire clip of B word shape can press from both sides two wires, makes whole brush rack plate assembly layout compacter in order.
As shown in Figure 7, it is the riveted joint schematic diagram of brush carrier reverse side, shown in figure, brush carrier is provided with riveted joint special hole, and brush bottom surface, room is provided with riveting column 25, and riveting column is through riveted joint special hole, and flatten and realize riveted joint with machinery, the advantage of riveting method is just can realize fixing between part without other other securing members, and simple in structure, the fastening fastness after riveted joint is good.
Below only with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure allows to change, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
