Abstract
The utility model discloses an electric brush subassembly, comprising at least one curve-shaped conductive sheet and a connecting piece, wherein the curve-shaped conductive sheet is used for generating fastening force towards the direction of a commutator; one end of each curve-shaped conductive sheet is contacted with the commutator and is symmetrically connected to two sides of the commutator; the other end of each curve-shaped conductive sheet is fixedly arranged on a motor; each curve-shaped conductive sheet is fixedly connected with the motor through the connecting piece; each curve-shaped conductive sheet is a U-shaped conductive sheet or a M-shaped conductive sheet; one side of an opening end of each U-shaped conductive sheet is connected with the commutator in a contacted manner; and the other end of the opening end of each U-shaped conductive sheet is fixedly connected with the connecting sheet. According to the electric brush subassembly which is formed by oppositely arranging the two M-shaped conductive sheets or the U-shaped conductive sheets to be contacted with the commutator, the direction of elastic force of an electric brush on the commutator is changed, so that the direction of an electric brush elastic conductive sheet in the electric brush subassembly to the commutator is inward, namely the direction of the commutator is tightly clamped; and therefore, the contact capability between the electric brush and the commutator is enhanced.
Description
Technical field
The utility model relates to a kind of motor component, particularly a kind of brush assembly of electric of motor.
Background technology
Brush is parts on the motor, and its effect is that electric current is introduced armature winding.Brush of the prior art is general to adopt a pair of elastic sheet metal to constitute.Fig. 1 is the structure chart of prior art center brush assembly apparatus, and is as shown in the figure, and an end of brush contacts with commutator; During work, brush is motionless, then rotation under the effect of electromagnetic force of armature; In existing electric machine assembly mounting technology, after general first rectification sub-member assembles, again with brush be in place with commutator on fixing conducting strip contact; For cooperating the miniature design demand of vibrating motor, the structure of brush is also more and more small, is commutator between two elastic sheet metals; Elastic sheet metal steps up commutator towards interior under the effect of elastic force; And commutator produces reaction force to elastic sheet metal, makes that original brush elastic force direction outwards is, promptly leaves the commutator direction.This kind product is being done when falling reliability test, because the effect of external force can cause brush outwards to open, causes brush and commutator loose contact, motor failure finally occurs.
Therefore need a kind ofly can closely cooperate with commutator and assemble simple brush parts.
The utility model content
In view of this, the utility model technical problem to be solved provides and a kind ofly can closely cooperate and assemble simple brush parts with commutator, improves the stability of the overall performance of motor.
The utility model is realized through following technical scheme:
The brush assembly of electric that the utility model provides comprises that at least one is used for producing a curved conducting strip that steps up power towards the commutator direction, and said each curved conducting strip one end is connected with the commutator contact, and the other end of said each curved conducting strip is fixed on the motor.
Further, also comprise brace, said curved conducting strip is fixedly connected on the motor through brace.
Further, said curved conducting strip is the U-shaped conducting strip, and said U-shaped conducting strip openend one side is connected with the commutator contact, and said U-shaped conducting strip openend opposite side is fixedly connected with brace.
Further, said U-shaped conducting strip is connected through the moulding of mould riveting with brace.
Further, said curved conducting strip is a M type conducting strip.
Further, the end that said curved conducting strip contacts with commutator is provided with a plurality of notch parts, and said notch part forms a plurality of electrically conductive elastic sheets.
Further, said curved conducting strip is two, is symmetrical set the both sides with commutator.
The beneficial effect of the utility model is: the utility model adopts two M type conducting strips or U-shaped conducting strip to be oppositely arranged to contact with commutator and the brush assembly of electric that forms; Changed the elastic force direction of brush to the commutator effect; Make that the brush elastic conducting strip in this brush assembly of electric is inside to the elastic force direction of commutator; Promptly clamp the commutator direction, strengthened the engagement capacity between brush and the commutator.
Other advantages, target and the characteristic of the utility model will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model and other advantages can realize and obtain through following specification and claims.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the structure chart of prior art center brush assembly apparatus;
The brush assembly of electric structure chart that Fig. 2 provides for the utility model embodiment;
The end view of the brush assembly of electric that Fig. 3 provides for the utility model embodiment.
Among the figure, 1 is curved conducting strip, and 2 is brace, and 3 are the riveting point, and 4 is notch part.
Embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.Should be appreciated that preferred embodiment has been merely explanation the utility model, rather than in order to limit the protection range of the utility model.
The brush assembly of electric structure chart that Fig. 2 provides for the utility model embodiment; The end view of the brush assembly of electric that Fig. 3 provides for the utility model embodiment; As shown in the figure: the brush assembly of electric that the utility model provides, comprise that at least one is used for producing a curved conducting strip 1 and brace 2 that steps up power towards the commutator direction, the curved conducting strip 1 among the embodiment of the utility model is two; Be symmetrical set both sides with commutator; The elastic force direction that this brush assembly of electric is produced under the situation that receives the commutator opposition is that inwardly promptly towards the direction of commutator, brush assembly of electric just can clamp commutator like this; Even receive under the external force effect also forming good contact effect at brush, solve product and in falling reliability test, cause cold failure mode because of brush opens with commutator.
Said each curved conducting strip one end is connected with the commutator contact, and the other end of said each curved conducting strip is fixed on the motor.
Said curved conducting strip 1 is fixedly connected on the motor through brace 2.
Said curved conducting strip 1 is U-shaped conducting strip or M type conducting strip, and said M type conducting strip or U-shaped conducting strip openend one side are connected with the commutator contact, and said U-shaped conducting strip openend opposite side is fixedly connected with brace.Said M type conducting strip or U-shaped conducting strip are connected through the moulding of mould riveting with brace, are fixedly connected through riveting point 3 with brace at M type conducting strip or U-shaped conducting strip one end.
