Description

A kind of brush box and its fit structure with brush carrier ring
Technical field
The present invention relates to the design of brush box in motor and brush box and brush, brush box and spring and brush box and brush carrier ring it Between matching relationship.
Background technique
The cavity portion of existing brush box cooperation brush is rectangle or square cross-section design, such as Fig. 6.To make brush box Type chamber stablize, be to bend and be mutually twisted structure using metallic sheet material;Respectively there is an installation card in the brush in-out end of brush box The installation card base of brush box is packed into brush carrier ring and riveted tightly and realizes the fixation of brush box on a mounting board by foot.Brush box is designed using this kind, Type chamber stability is poor, while mold design is complicated.
Summary of the invention
The purpose of the invention is to overcome disadvantages mentioned above, the design of brush box is improved in above-mentioned various aspects, Keep the design of brush box more reasonable, improve the cooperation of brush box Yu brush, brush carrier ring, while is easier the molding of brush box;Separately will Brush box is designed as front end closing in, and the big structure in rear end is conducive to cooperate with brush and spring.
Technical solution of the present invention:
A kind of brush box, box body are equipped with spring card slot 101, brush shunt welding card slot 102, spring escape groove 103, brush limiting stand 104 and fixing lug boss 105;
Spring card slot 101 is used to limit the space of spring 300, the pressure position for being applied to spring 300 on brush 200 Positioned at reasonable position;
Brush shunt welding card slot 102 is used to limit the space of the shunt welding of brush 200 and ensure that brush 200 because of normal loss And constantly to the mobile required space of commutator contact jaw;
Spring escape groove 103 is for defining the space of spring 300, and spring escape groove 103 is designed as ellipse;
Brush box limiting stand 104 is used to cooperate the shape of brush 200, reduces the finish dimensional of brush box 100, makes brush box 100 in front end It closes up, the big structure in rear end;
The fixing lug boss 105 is a pair of of card base, for fixation of the brush box 100 on brush carrier ring 400, i.e., by brush box 100 with Bending card base after brush carrier ring 400 is assembled together.
A pair of of card base of a kind of above-mentioned brush box, the fixing lug boss 105 is replaced with two pairs of card bases.
A kind of above-mentioned brush box, the in-out end of a pair of of card base change in location of the fixing lug boss 105 to brush 200, together When increase brush box bottom 106.
The fit structure of a kind of brush box and brush carrier ring, brush box 100 are fixed on brush carrier ring by fixing lug boss 105 On 400, i.e., a pair of of card base of bending fixing lug boss 105 or two pairs of card bases or add brush box bottom 106 200 in-out end of brush two Effective combination between the two can be realized in card base.
As it can be seen from the above scheme the invention has the characteristics that:
1, spring card slot provides suitable space for the movement of spring during the work time, while also spring being made to be applied to brush On pressure position be located at reasonable position.
2, brush shunt welding card slot provides suitable space for the shunt welding movement during the work time of brush, guarantees simultaneously Brush because of the normal loss due to constantly to commutator contact jaw it is mobile required for space.
3, spring escape groove provides suitable space for the movement of spring, avoids spring that bite occurs, while spring is kept away It allows slot to be designed as ellipse, is conducive to the type chamber stability of brush box.
4, brush limiting stand is mainly the shape for cooperating brush, reduces the finish dimensional of brush box, makes brush energy in brush box Balance movement.
5, fixing lug boss realizes fixation of the brush box on brush carrier ring.After brush box and brush carrier ring are assembled together, folding Effective combination between the two can be realized in the card base of curved installation fixing lug boss.
6, there are also other two kinds of structures to design for brush box simultaneously: one is a pair of of card bases of fixing lug boss to be replaced with two pairs of card bases It changes;Its another installation card placement of foot changes to the in-out end of brush, while increasing brush box bottom, and brush box bottom is by brush box two Face is engaged, and brush box Wall deformation is prevented, all up to the effective combination for realizing brush box and brush carrier ring.

Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to a kind of brush box proposed according to the present invention and its with the cooperation of brush carrier ring Structure specific embodiment, structure, feature and its effect, detailed description is as follows.
Referring to Fig. 1-4, a kind of brush box, box body is equipped with spring card slot 101, brush shunt welding card slot 102, spring escape groove 103, brush limiting stand 104 and fixing lug boss 105;
Spring card slot 101 is used to limit the space of spring 300, the pressure position for being applied to spring 300 on brush 200 Positioned at reasonable position;
Brush shunt welding card slot 102 is used to limit the space of the shunt welding of brush 200 and ensure that brush 200 because of normal loss And constantly to the mobile required space of commutator contact jaw;
Spring escape groove 103 is for defining the space of spring 300, and spring escape groove 103 is designed as ellipse;
Brush box limiting stand 104 is used to cooperate the shape of brush 200, reduces the finish dimensional of brush box 100, makes brush box 100 in front end It closes up, the big structure in rear end;
The fixing lug boss 105 is a pair of of card base, for fixation of the brush box 100 on brush carrier ring 400, i.e., by brush box 100 with Bending card base after brush carrier ring 400 is assembled together.
A pair of of card base of a kind of above-mentioned brush box, the fixing lug boss 105 is replaced with two pairs of card bases.
A kind of above-mentioned brush box, the in-out end of a pair of of card base change in location of the fixing lug boss 105 to brush 200, together When increase brush box bottom 106.
The fit structure of a kind of brush box and brush carrier ring, brush box 100 are fixed on brush carrier ring by fixing lug boss 105 On 400, i.e., a pair of of card base of bending fixing lug boss 105 or two pairs of card bases or add brush box bottom 106 200 in-out end of brush two Effective combination between the two can be realized in card base.
The principle of the invention: being illustrated in figure 5 brush stroke schematic diagram, and brush 200 is in the motor course of work, brush 200 Can be constantly lost with the contact surface of commutator, spring 300 pressure effect under, brush 200 can constantly in brush box 100 before It moves to make up the working loss of brush 200.To make brush 200 there are enough effective travels, need to guarantee brush 200 and spring 300 contact jaw has enough width, and is the contact performance for guaranteeing brush 200 and commutator, and the front end of brush 200 then needs Narrow.100 front and back of brush box is wide to be used cooperatively with the brush 100 in diagram, and brush box 100 is designed as front end and is closed up, The cooperation of brush box 100 Yu brush 200 is effectively guaranteed in the big structure in rear end.
The present invention is not only suitable for rain shaving electrical machine, is also applied for other motors.Brush box of the invention can in this patent Brush, spring and the brush carrier ring referred to is used cooperatively, and can also be used cooperatively with the part other than this patent.The brush box of the design It mainly is bent into shape using metal, is not related to the injection molding range of plastics.The cooperation of brush box and brush carrier ring is to utilize a pair Card base or two pairs of card bases or two card base of brush in-out end add the form of brush box bottom, all in the range of this patent is protected.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, appoint What is to the above embodiments according to the technical essence of the invention any simply to repair without departing from technical solution of the present invention content Change, equivalent variations and modification, all of which are still within the scope of the technical scheme of the invention.
