A core, one end are to be fixedly arranged in this axle center area, to combine with this Mandrel seat.
Wherein, this Mandrel seat and this flabellum group are the structures that is combined into one by plastic rubber shaping processing.
Wherein, on this Mandrel seat, also be provided with plurality of through holes.
Wherein, this axle center area comprises an opening, and establishes a flange in the periphery ring of this opening and protrude from this body, and this core is incorporated in this opening.
Wherein, the combination of this core and this Mandrel seat is to be drive fit.
Wherein, this Mandrel seat is a metal material.
Wherein, this core is a metal material.
Wherein, the material of this core Wei Bu Rust steel.
Wherein, this framework and these blades are one-body molded.
Wherein, this flabellum group is made up of plastic material.
Description of drawings
For further specifying technology contents of the present utility model, below in conjunction with embodiment and accompanying drawing is described in detail as after, wherein:
Fig. 1 is the sectional view of existing flabellum composite structure;
Fig. 2 is the sectional view of flabellum composite structure of the present utility model;
Fig. 3 and Fig. 4 are incorporated into the combination schematic representation of Mandrel seat for axle core of the present utility model.
Embodiment
Electric fan composite structure of the present utility model as shown in Figure 2, be its structure sectional view, this flabellum composite structure comprises a flabellum group 20, it is made up of integrated framework 22 and plural blade 24, normally make by the plastic material moulding, this framework 22 has a body 222 that is the plane, is formed with a perisporium 224 around it, and these blades 24 then are to be connected with respectively on this perisporium 224; One Mandrel seat 26 is that to be embedded in body 222 inner and surrounded by body 222, and its central authorities convex with an axle center area 30 and are exposed to outside the body 222; Other has a core 36, and the one end is to be installed in the axle center area 30 of Mandrel seat 26, and combines with Mandrel seat 26, and wherein this Mandrel seat 26 and an axle core 36 normally are made of metal material, and the material of axle core 36 use always Wei Bu Rust steel.
Wherein the structure of Mandrel seat 26 as shown in Figure 3, Mandrel seat 26 is to be provided with plurality of through holes 28, this axle center area 30 then comprises an opening 32, and convexes with a collar flange 34 in the periphery of opening 32, outside the body 222 that protrudes from framework 22.
When making this flabellum composite structure, as shown in Figures 3 and 4, be the axle center area 30 of elder generation with axle core 36 aiming axis core print seats 26, utilize tool that axle core 36 is assembled on Mandrel seat 26, make the two form friction tight state; Then when carrying out the shaping operation of flabellum group 20, the axle core 36 of Mandrel seat 26 and combination thereof is inserted in the shaping die, and then make shaping raw material coat Mandrel seat 26 and do not have the axle center area 30 of coating and carry out operations for forming, it is outer and axle center area 30 is exposed to make flabellum group 20 after the moulding be coated on Mandrel seat 26 with this, and then the structure that flabellum group 20 and Mandrel seat 26 are combined into one.Wherein, the perforation 28 of Mandrel seat 26 is the effects with the adhesive strength that strengthens Mandrel seat 26 and flabellum group 20.
In said structure, see through drive fit, axle core 36 is firmly to be incorporated on the Mandrel seat 26, is inserted in the forming die by the Mandrel seat 26 that area is big, is to make axle core 36 angles that complete just be positioned at Fan axial center C, can effectively overcome the easy deflection problem of existing axle core; On the other hand, when this blade structure drove running by motor, heating source was to be axle core 36, the heat energy that it produced see through reduced when Mandrel seat 26 conducts to the framework 22 of flabellum group 20 more many, so can effectively improve the thermal deformation resistant ability of blade structure.
Therefore, be different from the existing way that directly the axle core is fixedly arranged on the flabellum framework, the utility model is fixedly arranged on the axle core on one Mandrel seat, combine with the flabellum group by Mandrel seat again, to be combined to form the flabellum composite structure of one, not only the axle core is difficult for deflection yield is promoted when making, and can make the flabellum assembly after the combination have preferable adhesive strength and non-deformability.So the utility model not only can effectively improve the problem of existing axle core deflection and easy deflection, more can thereby effectively improve fan working life, the dither noise and the air quantity that also improve existing fan simultaneously reduce problem.Wherein, the axle core also has the simple advantage of the assembling of manufacturing with combining of Mandrel seat.
The above is by embodiment characteristics of the present utility model to be described, its purpose makes the personage who has the knack of this technology can understand content of the present utility model and is implementing according to this, and non-limiting claim of the present utility model, so, all other do not break away from the equivalence that spirit that the utility model discloses finishes to be modified or revises, and must be included in the claim of the following stated.
