Description
Technical field
The technical field of electric motor of automobile accessory is the utility model is related to, more particularly, to a kind of electric motor of automobile brush holder assembly
On brush.
Background technology
Brush is an important component of brush motor, and brush is to be fixed in certain position by brush holder, make its
Electric current is stably transmitted between fixed body and rotary body.For motor, brush holder and carbon brush are all very important parts.Brush holder
Structure be to maintain brush box part of the carbon brush on assigned position.Brush in electric motor of automobile brush holder assembly traditional at present,
Including brush body and the wire that may connect on brush holder, the head end face of brush body is provided with the rearwardly recessed arcwall face in direction.This
Kind brush is in practical work process, it may appear that larger grating is produced greatly with commutator contact surface using brush at initial stage,
Cause motor noise bigger than normal.
The content of the invention
For above-mentioned the shortcomings of the prior art, the purpose of this utility model, which is to provide one kind, can effectively reduce abrasion
Degree, extend the service life of product, and can effectively reduce the brush in the motor brush holder assembly of friction noise.
To realize above-mentioned purpose, the utility model provides following technical scheme：
A kind of brush in electric motor of automobile brush holder assembly, including brush body and the afterbody located at brush body may connect to brush holder
On wire, the head end face of brush body is provided with the rearwardly recessed arcwall face in direction, and the middle part on arcwall face is interval with some
Individual arc convex, deep-slotted chip breaker is formed between adjacent arc convex.
The utility model is further arranged to：The end face of the arc convex is the smooth transition surface of arc.
The utility model is further arranged to：The side of its close afterbody wherein in a side wall of the brush body is provided with recessed
Groove, wire is in groove.
The utility model is further arranged to：The section of the arc convex is trapezium structure or triangular structure.
The utility model is further arranged to：The height of the arc convex of the trapezoidal structure or triangular structure is homogeneous
Deng.
By using above-mentioned technical proposal, the technique effect that the utility model is reached is：By the head end for improving brush
Face structure, makes it reduce rubbing surface as far as possible so that this product can effectively reduce the degree of wear, and extend product uses the longevity
Life, and this product can be made effectively to reduce friction noise in the course of the work.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is side structure schematic view of the present utility model.
Fig. 2 is broken section structural representation of the present utility model.
Embodiment
Reference picture 1,2, for the brush disclosed in the utility model in a kind of electric motor of automobile brush holder assembly, including brush body 10
And afterbody located at brush body 10 and the wire 11 that may connect on brush holder, it is recessed that the head end face of brush body 10 is provided with rearwardly direction
If arcwall face 12, the middle part on arcwall face 12 is interval with several arc convex 13, shape between adjacent arc convex 13
Camber groove 14.Wherein, the end face of arc convex 13 is the smooth transition surface of arc.The section of arc convex 13 is trapezium structure
Or triangular structure, the height of the arc convex 13 of trapezoidal structure or triangular structure are equal.In the present embodiment, it is
The carefully and neatly done degree of the profile of product is high, and the section of arc convex 13 can be arranged to isosceles trapezoidal structure or isosceles triangle knot
The structure of structure or equilateral triangle, its isosceles trapezoidal structure either isoceles triangle tooth-shape structure or equilateral triangle tooth-shape structure
Number add up the height that size is less than brush, the specific number of teeth is different according to the different numbers of motor, designs this shape knot
Structure is in this scope of patent protection.
The side wherein in a side wall close to its afterbody of brush body 10 in the present embodiment is provided with groove 15, and wire 11 is located at
In groove 15.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
