Embodiment
In order further to understand feature of the present utility model, characteristics and technology contents, see also following about detailed description of the present utility model and accompanying drawing, appended accompanying drawing only provide with reference to and the explanation usefulness, non-in order to limit the utility model.
The utility model provides a kind of fan assembly, is applied to any occasion that must dispel the heat, for example is applied to the heat transmission fan assembly of various computer, and the utility model does not limit.
See also Fig. 2～shown in Figure 5, Fig. 2, Fig. 3 are disclosing three-dimensional exploded view of the present utility model and three-dimensional sectional exploded view respectively, and Fig. 3 A is the sectional axonometric drawing after axle sleeve 51 amplifies in the part, and Fig. 4, Fig. 5 are respectively stereogram and the sectional axonometric drawing of bearing 7.The utility model fan assembly 400 comprises: a fan frame 4, a stator 5, an impeller 6 and a bearing 7.
Bearing 7 wherein, its urceolus 72 outwards protrudes (circular-arc protrusion) along the periphery of upper end one first catch flanges 721, urceolus 72 also outwards protrudes (circular-arc protrusion) along the periphery of lower end one second catch flanges (723 or 723A) is arranged, and the buckle direction of the buckle direction of first catch flanges 721 and second catch flanges (723 or 723A) is opposite each other, see also Fig. 6, shown in Fig. 6 A, so that first catch flanges, 721 energy from top to down correspondences are snapped in the first recessed edge 513 of axle sleeve 51, and make second catch flanges (723 or 723A) the corresponding second recessed edge 514 that is snapped in axle sleeve 51 from bottom to up, thereby allow bearing 7 firmly be fixed in the axle sleeve 51.In addition, the upper end of inner core 71 is open end (not indicating component symbol), and the lower end then is closed end 711; Moreover closed end 711 is the arc concavity, and an end in axle center 62 then is convex arc-shape corresponding to this closed end 711.In addition, aforementioned joint 73 radially close to closed end 711 and be positioned at first catch flanges 721 of urceolus 72 and second catch flanges (723 or 723A) between, so that the part that inner core 71 Yin Gaore outwards expand, can all be contained in the clearance space 74, thereby can not have influence on stationary state between urceolus 72 and the axle sleeve 51.Again, the outer wall of urceolus 72 also can outwards convex with a plurality of clipping blocks 724 that are adjacent to first catch flanges 721, and each clipping block 724 is suitable to be embedded in appointing between adjacent two projections 515 of axle sleeve 51 and clip each other.
In present embodiment, see also Fig. 4, shown in Figure 5, the underpart of urceolus 72 by each interval and axially (or, towards axle sleeve 51 directions) a plurality of pins 722 of protruding out constitute, and those pins 722 still each other in corral around, each pin 722 and along its free-ended outer rim to being protruded with second catch flanges 723.As figure, the quantity of pin 722 is same as the quantity of projection 515, with when being assembled in bearing 7 axle sleeve 51 in, the space between wantonly two pins 722 can the corresponding projection 515 of confession by and obstruction do not arranged, the easness when relative then increase is assembled.
In another embodiment, see also shown in Fig. 4 A, the underpart of urceolus 72 is complete tubular, in the lower end of urceolus 72 then along its periphery to being protruded with the second catch flanges 723A.As figure, because the second catch flanges 723A is a complete circle, just do not have the part that can supply projection 515 to pass through, therefore when being assembled in bearing 7 in the axle sleeve 51, will increase some degree of difficulty and be difficult to assembling, but only must strengthen the assembling power again, still can finish assembling.
Accordingly, when 400 entrys into service of the utility model fan assembly, the heat that comes from axle center (metal material) 62, although the inner core 71 of bearing (hard plastic cement material) 7 can outwards expand because of Gao Re, but owing to be formed with clearance space 74 between the inside and outside tube 71,72, can have only inner core 71 that thermal distortion takes place because of the obstruct of clearance space 74, and the part that inner core 71 outwards expands because of Gao Re, can also can allow expansion because of the existence of clearance space 74, can not have influence on the stationary state between urceolus 72 and the axle sleeve 51 fully.Moreover, can correspondence be snapped in the first recessed edge 513 and the second recessed edge 514 by first catch flanges 721 and second catch flanges (723 or 723A), so that bearing 7 can firmly be fixed in the axle sleeve 51, needn't re-use clasp fully (with reference to the component symbol of prior art Fig. 1: 33), be can be more light and convenient in the assembling.
Wherein, see also shown in Fig. 5 and Fig. 6 A, first catch flanges 721 and second catch flanges (723 or 723A) elasticity are all from inside to outside oppressed in inwall 512, so that bearing 7 has better steadiness; But because the external diameter of first catch flanges 721 is greater than the external diameter of second catch flanges 723, therefore the packing degree of first catch flanges 721 when elasticity is oppressed will be greater than the packing degree of second catch flanges (723 or 723A), so that bearing 7 is first comparatively smooth what assemble, when first catch flanges 721 entered the upper end of axle sleeve 51, it was urgent just to become.
In sum, the utility model has following effect compared to prior art: (one) can be with heat rejection between inside and outside tube 71,72, the part that inner core 71 Yin Gaore are outwards expanded can not have influence on the stationary state between urceolus 72 and the axle sleeve 51 because of clearance space 74.(2). can firmly be fixed in the axle sleeve 51 by bearing 7, need not using clasp, thus can be more light in assembling and make things convenient for.
In addition, the utility model also has other effect: by bearing 7 being changed to inside and outside tube 71,72 designs with difference of height, when making bearing 7, to have the effect of the demoulding of being easy to, be the up-to-standard rate that can promote when making bearing 7 relatively, make the utility model can prevent that the design of thermal distortion is more valuable.Lower end retraction by inner core 71 is within the lower end of urceolus 72, to have the effect that reduces cost.Lower end by inner core 71 is closed end, can excessively not be coupling in bearing 7 to limit axle center 62, and then make the upper end of inner core 71 can not touch impeller 6.Be arc concavity and the convex arc-shape that corresponds to each other by the closed end 711 of inner core 71 and the free end in axle center 62, be beneficial to the rotation in axle center 62.Joint 73 by bearing 7 close to closed end 711 and be positioned at first catch flanges 721 of urceolus 72 and second catch flanges (723 or 723A) between, so that inner core 71 Yin Gaore and the outside expansion that produces can not have influence on the stationary state between urceolus 72 and the axle sleeve 51.Each clipping block 724 by urceolus 72 outer walls is suitable to be embedded in the appointing between adjacent two projections 515 of axle sleeve 51, with clip each other.
The above person, it only is preferable possible embodiments of the present utility model, non-so limit to claim of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all reason is with being contained in the interest field of the present utility model.
