As the further improved technical solution of the utility model, the wall portion is equipped with two limiting sections of alignment.

As the further improved technical solution of the utility model, two opposite lateral surfaces of the carbon brush first end are set respectively There are two boss of alignment.

As the further improved technical solution of the utility model, the limiting section is turned over for what wall portion end was bent inwardly Side.

As the further improved technical solution of the utility model, the elastic component is set as spring or torsional spring.

As the further improved technical solution of the utility model, the carbon brush first end, which is equipped with, is inserted into the convex of elastic component Portion.

As the further improved technical solution of the utility model, the brush carrier is equipped with the gear for blocking the accepting hole other end Plate, the elastic member presses are between baffle and carbon brush.

As the further improved technical solution of the utility model, the baffle is equipped with the convex closure for being inserted into elastic component.

Compared to the prior art, the wall portion of the brush carrier of the utility model carbon brush component is equipped with the limiting section being located in opening, The first end of the carbon brush is equipped with the boss being aligned with limiting section, and the limiting section is spaced with boss on carbon brush moving direction It opens, so set, when carbon brush abrasion is to predetermined length, boss and the limiting section support of carbon brush are close together, and limiting section prevents carbon Brush continues to move to, and carbon brush is promoted no longer to be contacted with commutator, and motor automatic stop work, carbon brush will not be polished, it is therefore prevented that bullet Property part contacted with commutator, prevent arcing and damage commutator and prevent motor burn machine, the utility model carbon brush component There is automatic stop, and it is simple in structure, production cost is low.

Specific embodiment

In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with the accompanying drawings and it is embodied The utility model is described in detail in example.

It please refers to Fig.1 to shown in Fig. 5, the utility model discloses a kind of carbon brush component 100, to be slided with commutator 200 Dynamic contact.The carbon brush component 100 includes brush carrier 10, carbon brush 20 and elastic component 30.

The brush carrier 10 is equipped with accepting hole 11, encloses several wall portions 12 on the outside of the accepting hole 11 and block the receipts Hold the baffle 13 in hole 11, one end of the accepting hole 11 is equipped with opening 110, and the baffle 13 blocks another in the accepting hole 11 End, the wall portion 12 are equipped with two limiting sections 120, and the limiting section 120 is located in the opening 110, specifically, two opposite institutes Two limiting sections 120 that wall portion 12 is equipped with alignment are stated, the limiting section 120 is the flange that 12 end of wall portion is bent inwardly. The baffle 13 is equipped with the convex closure 130 being located in the accepting hole 11.

The carbon brush 20 includes first, second opposite end 21,22, and the first end 21 is located in the accepting hole 11, The opposite lateral surface of 21 liang of the first end is equipped with the boss 210 for being aligned and being spaced apart with the limiting section 120, and described first End 21 is additionally provided with the protrusion 211 being inserted in the elastic component 30, and the second end 22 stretches out the brush via the opening 110 10 are held, with 200 sliding contact of commutator.

The elastic component 30 is set as spring or torsional spring, is contained in the accepting hole 11, and be pressed on the baffle Between 13 and the carbon brush 20, promote the carbon brush 20 that there is the direction force towards the commutator 200.The elastic component 30 One opposite end accommodates the protrusion 211 of the carbon brush 20, and another opposite end accommodates the convex closure 130 of the baffle 13, prevents institute Elastic component 30 is stated to loosen.

The carbon brush 20 of the utility model carbon brush component 100 may wear to before predetermined length, the carbon brush 20 it is described Boss 210 is spaced apart with the limiting section 120, when the carbon brush 20 may wear to predetermined length, the carbon brush 20 it is described convex Platform 210 is abutted together with the limiting section 120, and the limiting section 120 prevents the carbon brush 20 from continuing to move to, and promotes the carbon Brush 20 is no longer contacted with the commutator 200, and motor automatic stop work, the carbon brush 20 will not be polished, it is therefore prevented that described Elastic component 30 is contacted with the commutator 200, is prevented arcing and damage commutator and is prevented motor from burning machine, this practicality Carbon brush component 100 have the function of automatic stop and also it is simple in structure, production cost is low.

In addition, above example is merely to illustrate the utility model and not limits the described technical side of the utility model Case, understanding of this description should be based on persons of ordinary skill in the field, although this specification is with reference to above-mentioned Embodiment has been carried out being described in detail to the utility model, still, it will be understood by those of ordinary skill in the art that, affiliated skill The technical staff in art field still can be modified or replaced equivalently the utility model, and all do not depart from this practicality newly The technical solution of the spirit and scope of type and its improvement should all be covered in the right of the utility model.
