Description
一種風扇結構，尤指一種透過一體包射之方式將風扇之輪轂與金屬材質之扇葉結合一體的風扇結構。 A fan structure, in particular, a fan structure in which a hub of a fan and a blade of a metal material are integrated by means of an integrated package.
傳統風扇主要透過一體射出成型之方式以製造塑膠材質之輪轂及扇葉，並此種方式廣泛的被應用在大多數的風扇製造上。 Conventional fans are mainly used to manufacture plastic hubs and blades by means of integral injection molding, and this method is widely used in most fan manufacturing.
然而該種射出成型的塑膠風扇並無法滿足所有使用者的使用需求，例如具高溫高壓環境中使用或者是扇葉本體要求較強結構強度或是風扇需要更多扇葉數的設計或其他的要求下需要使用金屬製造的風扇扇葉，進而達到特殊之特性或增加使用壽命或增加風量，但金屬之熔化溫度過高無法使用射出成型之方式進行製造，故先將金屬材質輪轂製造成型後，再將金屬材質之葉片透過緊配之方式嵌設於前述輪轂之外緣欲開設之槽口中進行組裝組成一風扇扇葉，另者，亦有業者透過焊接之方式將風扇金屬扇葉固定於輪轂之外緣藉此完成金屬扇葉與金屬輪轂的組裝。 However, this kind of injection molded plastic fan can not meet the needs of all users, such as the use of high temperature and high pressure environment or the design of the blade body requires strong structural strength or the fan needs more fan blades or other requirements. It is necessary to use a fan blade made of metal to achieve special characteristics or increase the service life or increase the air volume. However, if the melting temperature of the metal is too high, it cannot be manufactured by injection molding. Therefore, after the metal wheel hub is molded, The blade of the metal material is embedded in the slot of the outer edge of the hub to be assembled into a fan blade, and the fan blade is fixed to the hub by welding. The outer edge thereby completes the assembly of the metal blade and the metal hub.
前述習知製造方法仍具有缺點，如透過沖壓之方式將金屬扇葉嵌設於該風扇輪轂外緣所設置之槽口中時，需透過大量外力衝擊之方式將金屬葉片迫入該輪轂外緣之槽口，但當金屬扇葉與該風扇輪轂結合時容易因衝擊力使該金屬扇葉變形或破裂且配重不易平衡，進而使不良率增加。 The above conventional manufacturing method still has the disadvantages that, when the metal blade is embedded in the notch provided in the outer edge of the fan hub by punching, the metal blade is forced into the outer edge of the hub by a large amount of external force impact. The notch, but when the metal blade is combined with the fan hub, the metal blade is easily deformed or broken by the impact force, and the weight is not easily balanced, thereby increasing the defective rate.
再者，透過焊接之方式將金屬扇葉固定於該輪轂外緣也因如金屬扇葉材質係為鋁材質，而輪轂如為鐵材質則需透過特殊焊接方式使得以進行焊接作業，雖可完成兩者間的結合，但則是勢必增加製造之成本。 Furthermore, the metal blade is fixed to the outer edge of the hub by welding, because the metal blade material is made of aluminum, and if the wheel is made of iron, it needs special welding to make the welding work, although it can be completed. The combination of the two, but it is bound to increase the cost of manufacturing.
故如何改善習知透過沖壓或焊接工法，且在傳統塑膠風扇與金屬風扇之中各取其優點(即金屬扇葉與塑膠輪轂的結合)，實為該項業者首要解決之問題。 Therefore, how to improve the conventional method through stamping or welding, and the advantages of traditional plastic fans and metal fans (ie, the combination of metal blades and plastic wheels) is the primary problem for the industry.
爰此，為解決上述習知技術之缺點，本創作之主要目的係提供一種透過包射之方式令金屬扇葉與風扇輪轂結合一體的風扇結構。 Accordingly, in order to solve the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to provide a fan structure in which a metal blade and a fan hub are integrated by means of a package.
為達上述之目的，本創作係提供一種風扇結構，係包含：一輪轂；所述輪轂具有一外緣部，該外緣部嵌設複數扇葉體，該等扇葉體係為金屬材質，並該等扇葉體分別具有一第一端及一第二端，該等扇葉體之第一端透過一體包射之方式與該輪轂之外緣部結合，該等扇葉體另一端之第二端係呈自由端。 For the purpose of the above, the present invention provides a fan structure, comprising: a hub; the hub has an outer edge portion, and the outer edge portion is embedded with a plurality of blade bodies, and the fan blade system is made of metal, and Each of the fan blades has a first end and a second end, and the first ends of the fan blades are coupled to the outer edge of the hub by means of integral encapsulation, and the other end of the fan blades The two ends are free ends.
透過本創作之風扇結構除可解決習知透過緊配方式組合之缺失外，除扇葉具有較佳之結構強度外，更可大幅降低製造成本與縮短工時者。 In addition to the loss of the conventional combination of tight fitting methods, the fan structure of the present invention can greatly reduce the manufacturing cost and shorten the working hours, in addition to the better structural strength of the blade.
