Abstract
The utility model discloses a kind of fan motor for automobile, including shell, the shell includes drive end bearing bracket, middle casing and rear end cap, heat emission hole after being set on the drive end bearing bracket, the rear end cap is tightly connected with middle casing, and is provided with thermal window on the middle casing end of rear end cap.The utility model fan motor for automobile, by setting thermal window on middle casing so that the heat generated inside motor can quickly shed shell, be avoided that motor because radiate it is bad caused by temperature rises excessively high, aging aggravation, electrical machinery life shortens the problem of.
Description
Technical field
The utility model is related to automobile technical field, more particularly to a kind of motor of automobile fan.
Background technology
In the prior art, using closed casing as motor stator, fixed rotor component and magnet steel make fan motor for automobile
The rotor of fan motor for automobile does the circular motion of rule after powered up.
But the casing of this closed structure makes the heat that motor generates not shed quickly in motor operation course,
It can steeply rise motor internal temperature, insulation ag(e)ing aggravation, electrical machinery life shortens.
And existing motor housing, end cap is to be fixed on by rivet on middle casing thereafter, using rivet, is made
Special rivet must be needed, is increased manufacturing cost；And number of rivets is usually two, riveting reliability is relatively low.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fan motor for automobile, to solve automobile in the prior art
The technical issues of housing of fan electromotor is closed structure, and motor internal heat can not quickly shed.
The utility model fan motor for automobile, including shell, the shell includes drive end bearing bracket, middle casing and rear end cap,
Heat emission hole after being set on the drive end bearing bracket, the rear end cap are tightly connected with middle casing, and close to the middle casing of rear end cap
Thermal window is provided on end.
Further, the thermal window is rectangle.
Further, the thermal window is to have eight along middle casing circumferential directions.
Further, set there are four curved flanges on the edge of the drive end bearing bracket, be provided on the edge of the rear end cap
Five curved flanges are provided with the card slot of curved flanges interference fit on the both ends end face of the middle casing, and close to card slot
V-shaped groove is additionally provided on the middle casing end face at both ends, the fixture block for fixing curved flanges is formed between the V-shaped groove and card slot.
The beneficial effects of the utility model：
1st, the utility model fan motor for automobile, by setting thermal window on middle casing so that inside motor
The heat of generation can quickly shed shell, be avoided that motor because radiate it is bad caused by temperature rise excessively high, aging aggravation, electrical machinery life
The problem of shortening.
2nd, the utility model fan motor for automobile, by setting curved flanges on forward and backward end cap edge, in middle case
Card slot is set on body, and for shell using curved flanges and this structure of card slot riveted, eliminating conventional enclosure riveted structure must
The rivet of palpus, has saved cost.And the forward and backward respective riveted position of end cap is more, and riveted reliability is high, makes motor worked
Be not in the problem of end cap loosens in journey.
Description of the drawings
Fig. 1 is the dimensional structure diagram of fan motor for automobile in embodiment；
Fig. 2 is another angle dimensional structure diagram of fan motor for automobile in embodiment.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in the figure, the present embodiment fan motor for automobile, including shell, the shell includes drive end bearing bracket 1, middle casing 2
With rear end cap 3.Heat emission hole 4 after being set on the drive end bearing bracket, the rear end cap are tightly connected with middle casing, and close to rear end cap
Middle casing end on be provided with thermal window 5.
Fan motor for automobile in the present embodiment, by setting thermal window on middle casing so that production inside motor
Raw heat can quickly shed shell, be avoided that motor because radiate it is bad caused by temperature rise excessively high, aging aggravation, electrical machinery life contracting
The problem of short.
In the present embodiment, the thermal window is rectangle, and the thermal window is to have along middle casing circumferential directions
Eight, heat dissipation area is big, good heat dissipation effect.
It in the present embodiment, sets there are four curved flanges 6 on the edge of the drive end bearing bracket, is set on the edge of the rear end cap
It puts there are five curved flanges 6, the card slot of curved flanges interference fit is provided on the both ends end face of the middle casing, and it is close
V-shaped groove 7 is additionally provided on the middle casing end face at card slot both ends, is formed between the V-shaped groove and card slot and fixes curved flanges
Fixture block 8.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover among the right of the utility model.
