【Embodiment】
The above-mentioned purpose and its structure of the present invention and characteristic functionally, will be explained according to the preferred embodiment of institute's accompanying drawings.
Figure 1A is perspective exploded view of the present invention；Figure 1B is the three-dimensional combination diagram of the present invention；Fig. 2A is the side wall of wheel hub of the present invention and the schematic diagram of flabellum corresponding relation；Fig. 2 B are plugged in the schematic diagram of the slot of the side wall of wheel hub for the flabellum of the present invention；Fig. 3 A are the schematic perspective view at another visual angle of lid of the present invention；Fig. 3 B are the schematic diagram of lid of the present invention and flabellum corresponding relation.Fan wheel structure 10 of the invention for example, centrifugal impeller, an including wheel hub 11 and the plural lid 13 of flabellum 12 and one as shown in the figure.Wheel hub 11 has a top surface 111, the top surface 111 is provided with the side wall 112 protruded out upward from top surface 111, the side wall 112 is circumferentially positioned at the outer rim of the top surface 111 and protrudes out the top surface 111 that end 1121 protrudes the wheel hub 11 with one, and the side wall 112 has plural slot 113, the grade slot 113 is arranged at intervals and protrudes out one interface 1131 of the formation of end 1121 at this respectively（Such as Fig. 2A）, the side wall 112 has a center A of the inner side 1127 towards the wheel hub 11, and 1128 opposite inner sides 1127 of an outside, and an accommodation space 114 is defined in the inner side 1127 of the side wall 112 and on the top surface 111.
The grade flabellum 12 is circular combined with the side wall 112, especially as shown in Figure 2 A and 2 B, each flabellum 12 have 121 pairs of a plug division should wheel hub 11 slot 113, be then axially inserted into from the interface 1131 in the slot 113.The plug division 121 along the wheel hub 11 one radially towards the wheel hub 11 center protrude out a binding end 122 positioned at the side wall 112 inner side 1127 accommodation space 114 in, the binding end 122 has one to combine recess 1221 on the top surface 111 of the wheel hub 11, two button arms 1223 are formed with the both sides for combining recess 1221, the plug division 121 has protruded out a free end 123 towards the center A of the opposite wheel hub 11.Because the plug division 121 is extended with the binding end 122 in the inner side 1127 of side wall 112, the free end 123 of then extension is then outside the outside 1128 of the side wall 112, therefore the plug division 121 is located between the binding end 122 and the free end 123.
The lid 13 is combined with the top surface 111 of the wheel hub 11, and in the accommodation space 114 of the inner side 1127 of the side wall 112, and the lid 13 is that annular lid has a central open-work 131 and the plural docking of engagement groove 132 and one side 137（As shown in Figure 3A）Top surface 111 of the correspondence with reference to the wheel hub 11, especially as shown in Fig. 3 A and Fig. 3 B, in each engagement groove 132 the combination recess 1221 that element 133 coordinates the grade flabellum 12 is fixed provided with one, wherein binding end 122 of the grade engagement groove 132 respectively in connection with the grade flabellum 12, and make the fixing element 133 in the engagement groove 132 buckle into this with reference to recess 1221 to fix the grade flabellum 12, and the clamp fixing element 133 of being taken advantage of a situation after the button arm 1223 for combining recess 1221 both sides buckles into this with reference to recess 1221 in the fixing element 133, make the binding end 122 of the flabellum 12 more firm combined with the lid 13, flabellum 12 is prevented because the operating of wheel hub 11 is thrown out of by centrifugal action.
The material of the above-mentioned flabellum 12 of the present invention is made up of metal using punching press, and the thickness of flabellum 12 is preferably less than 0.15mm ultrathin flabellum, and the material of the wheel hub 11 and lid 13 may be selected to be plastic cement and is made using ejection formation.
Multiple reference Figure 1A and Fig. 3 A, the top surface 111 of the wheel hub 11 is provided with plural number depression by such as projection of fitting 116 or convex grain, and grade depression is disposed on by fitting 116 at the inner side 1127 of the close side wall 112（As shown in Figure 1A）, 137 pairs of the docking side of the lid 13 should the top surface 111 of wheel hub coordinate the depression by fitting 116 provided with the plural number protrusion such as shrinkage pool of connector 136.Especially as shown in Fig. 4 A, Fig. 4 B and Fig. 4 C, the depression is inserted through by after fitting 116 by the protrusion connector 136, the end of running through for making the grade protrude connector 163 through rivet hot processing procedure forms a gland, and the diameter of the gland is more than internal diameter of the depression by fitting 116（As shown in Figure 4 C）, so that the lid 13 is fixed on the top surface 111 of the wheel hub 11, while the binding end 122 of the flabellum 12 is combined closely in engagement groove 132, this combines the button of recess 1121 and two arm 1223 closely solid fixing element 133 of button（As shown in Figure 4 B）.
Foregoing rivet hot processing procedure is a kind of two stage processing procedure.First stage, by lid 13 and flabellum 12 and pre- group of wheel hub 11 and put to board, the protrusion connector 136 of lid 13 is directly blowed to using hot blast, hot blast temperature is depending on the plasticization temperature of plastic material of the lid 11 is made.Second stage, is pressed on protrusion connector 136 under the cold riveting stake that capitiform is molded using a tool, and performing riveted shaping makes the combination that lid 13 and wheel hub 11 are completed while forming a gland and then cooling through end of the protrusion connector 163.
However, being not limited to this, implement in another substitute, be put among mould, then directly formed the lid 13 on the top surface 111 of wheel hub 11 and combined with the binding end 122 of flabellum 12 using injection molding method after in advance combining flabellum 12 and the wheel hub 11.In addition, implementing in another substitute, the lid 13 and wheel hub 11 open up corresponding open-work respectively, and then the rivet of plastic cement material or metal material is inserted to the open-work of lid 13 and wheel hub 11, so that both combine.
Furthermore, the present invention does not limit to above-mentioned implementation, implement in another substitute, as shown in figure 5, the side wall 112 of foregoing wheel hub 11 can also be omitted, therefore the binding end 122 of the flabellum 12 is advance combined with the engagement groove 132 of lid 13, and then around and radial be arranged on around lid 13, then the docking side 137 of lid 13 is again combined with the top surface 111 of the wheel hub 11, so that the grade flabellum 12 is fixed on the top surface 111 of the wheel hub 11, and towards the outside radiated entends of wheel hub 11.
By above-mentioned, radial projection of the present invention by the plug division 121 of flabellum 12 along the wheel hub 11 has a binding end 122 in the accommodation space 114, and via lid 13 combined with the wheel hub 11, so that flabellum 12 must be fixed on around wheel hub, to strengthen bond strength between flabellum 12 and wheel hub 11, improve known flabellum to be connected with wheel hub directly welding or clamping and cause the problem of junction is easily broken off, and improvement causes the problem of known wheel hub load-carrying is uneven using solder joints.
Only as described above, the only preferably feasible embodiment of the present invention is changed, should be all contained in the interest field of this case for it using the above-mentioned method of the present invention, shape, construction, device such as.
