Description
本發明係關於一種風扇,尤其是一種易於進行電源接線之安裝作業,且具有具有肋條(或靜葉)的風扇。The present invention relates to a fan, and more particularly to an installation work that is easy to perform power supply wiring and has a fan having ribs (or vanes).
習知風扇通常具有一電源接線,該電源接線的設置位置必須經過妥善處理安排,以確保該風扇於實際運作過程中,可有效避免該電源接線鬆脫或捲入該風扇中,使該風扇正常運作;再者,目前市面上常見之習知風扇大致可區分為二種,其中第一種習知風扇並未具有肋條(或靜葉)設計,而第二種習知風扇則具有肋條(或靜葉)設計,該兩種習知風扇之電源接線的處理方式亦不相同。Conventional fans usually have a power supply wiring, and the setting position of the power supply wiring must be properly arranged to ensure that the fan is in the actual operation process, and the power supply wiring can be effectively prevented from being loosened or caught in the fan, so that the fan is normal. In addition, the conventional fans currently available on the market can be roughly divided into two types. The first conventional fan does not have a rib (or vane) design, while the second conventional fan has ribs (or The design of the static blade) is different for the power wiring of the two conventional fans.
舉例而言,如中華民國公告第449682號「超薄冷卻風扇構造」發明專利及中華民國公告第443435號「鼓風扇之電線扣具結構改良」新型專利等,係揭示前述第一種習知風扇。該第一種習知風扇主要係於一殼體(或稱風扇座)形成一槽道(或稱導線槽),使電源接線可直接經由該槽道(或稱導線槽)穿伸至外部以便外接電源,惟該電源接線仍須透過相當複雜的繞設固定方式,故造成組裝上的諸多不便。For example, the invention patent of the "Ultra-thin cooling fan structure" of the Republic of China Bulletin No. 449682 and the new patent of the "Wireless cable structure improvement of the drum fan" of the Republic of China Announcement No. 443435 disclose the first conventional fan. . The first conventional fan is mainly formed in a casing (or a fan seat) to form a channel (or a wire slot), so that the power cable can be directly penetrated to the outside through the channel (or wire slot). External power supply, but the power supply wiring still has to pass through a rather complicated winding and fixing method, which causes inconvenience in assembly.
另外,請參照第1圖所示,如中華民國公告第502831號「風扇理線結構」新型專利,係揭示前述第二種習知風扇。該第二種習知風扇70具有一理線結構71(即為肋條)及數個導風孔73;該理線結構71包含一底部 711、二側面支持部712及二擋板部713;藉此,該理線結構71係使一線材72(即電源接線)以一迂迴方式置於該底部711、側面支持部712及擋板部713之間。前述第二種習知風扇70的主要問題在於:為確保該線材72在穿伸至該風扇70外部時,該線材72不會遮擋該導風孔73而影響驅風效果;因此,一般而言,必須先將該線材72之一端經由該風扇70下方的導風孔73穿伸外部,再利用迀迴繞線方式使該線材72依序卡掣於該底部711、側面支持部712及擋板部713之間,如此方可確保該線材72不至於遮擋該擋風孔73;然而,確也因此導致該線材72之組裝作業的困難度增加。另外,該習知風扇70用以固定該線材72的結構亦相當複雜,故相對提高整體製造成本。整體而言,針對具有肋條(或靜葉)設計的習知風扇70仍有加以改善之必要。In addition, please refer to FIG. 1 , for example, the new patent of the “Fan Cable Management Structure” of the Republic of China Announcement No. 502831 discloses the aforementioned second conventional fan. The second conventional fan 70 has a cable management structure 71 (ie, a rib) and a plurality of air guiding holes 73; the cable management structure 71 includes a bottom portion. 711, two side support portions 712 and two baffle portions 713; thereby, the cable management structure 71 is such that a wire 72 (ie, power supply wiring) is placed in the bottom portion 711, the side support portion 712, and the bezel portion in a meandering manner. Between 713. The main problem of the second conventional fan 70 is that in order to ensure that the wire 72 penetrates outside the fan 70, the wire 72 does not block the air guiding hole 73 and affects the wind blowing effect; therefore, in general, One end of the wire 72 must be firstly passed through the air guiding hole 73 under the fan 70, and then the wire 72 is sequentially clamped to the bottom portion 711, the side support portion 712 and the bezel portion by means of winding back. Between 713, it is ensured that the wire 72 does not block the windshield 73; however, it also causes an increase in the difficulty of assembling the wire 72. In addition, the structure of the conventional fan 70 for fixing the wire 72 is also quite complicated, so that the overall manufacturing cost is relatively increased. Overall, there is still a need for improvements to the conventional fan 70 having a ribbed (or vane) design.

請參照第4圖所示,該導線口16之第一抵壓面161更佳可形成一第一階層部162,該定位件17之第二抵壓面171對應該第一階層部162之形狀更佳亦可形成一第二階層部172,且該第一階層部162及該第二階層部172可 相互對應卡合。藉此,當該第一抵壓面161及該第二抵壓面171共同壓掣夾合該電源接線40時,該電源接線40可配合該第一階層部162及該第二階層部172形成如圖所示之轉折狀態,以提供較佳的防拉扯功能,而可有效的防止外力不當拉扯該電源接線40,確保該電源接線40之一端更不易自該電性連接埠32鬆脫。Referring to FIG. 4, the first pressing surface 161 of the wire opening 16 preferably forms a first layer portion 162, and the second pressing surface 171 of the positioning member 17 corresponds to the shape of the first layer portion 162. More preferably, a second hierarchical portion 172 can be formed, and the first hierarchical portion 162 and the second hierarchical portion 172 can be Corresponding to each other. Therefore, when the first pressing surface 161 and the second pressing surface 171 jointly press and clamp the power connection 40, the power connection 40 can be formed to cooperate with the first hierarchical portion 162 and the second hierarchical portion 172. The turning state as shown in the figure provides a better anti-pull function, and can effectively prevent the external force from improperly pulling the power wiring 40, ensuring that one end of the power wiring 40 is less likely to be loosened from the electrical connection port 32.
請參照第5及6圖所示,係揭示另一種基板30a結構,該基板30a之電性連接埠32較佳係位於該扇輪50之永久磁鐵512的旋轉範圍外,更詳言之,使該電性連接埠32可位於該永久磁鐵512的外周緣與該側牆部的內側壁之間。藉此,如第7圖所示,在該扇輪50之永久磁鐵512至該基板30a之間所形成的間距(D),由於無須容置該電性連接埠32(如銲點等)及電源接線40,因此,該間距(D)亦可相對縮小至適當距離,以便有效降低本發明風扇之整體軸向高度。Referring to FIGS. 5 and 6, another structure of the substrate 30a is disclosed. The electrical connection 32 of the substrate 30a is preferably located outside the rotation range of the permanent magnet 512 of the fan wheel 50. More specifically, The electrical connection port 32 can be located between the outer circumference of the permanent magnet 512 and the inner side wall of the side wall portion. Therefore, as shown in FIG. 7, the spacing (D) formed between the permanent magnet 512 of the fan wheel 50 and the substrate 30a does not need to accommodate the electrical connection 32 (such as solder joints, etc.) and The power supply wiring 40, therefore, the spacing (D) can also be relatively reduced to an appropriate distance to effectively reduce the overall axial height of the fan of the present invention.
請參照第8及9圖所示,再揭示另一種基板30b結構,該接線固定部20’之結合端21較佳位於該基準線(L)上,配合該接線固定部20’之位置,該基板30b之外周緣較佳可形成一凸部33,該凸部33朝向該扇框10之導線口16,且該凸部33亦位於該基準線(L);另外,該凸部33可結合該接線固定部20’,該電性連接埠32係形成於該凸部33之表面。藉此,利用該基板30b之凸部33設計,同樣可使該基板30b之電性連接埠32位於該扇輪50之永久磁鐵512的旋轉範圍外,更重要的是,當該凸部33結合於該接線固定部20’後,由於該電性連接埠32形 成於該凸部33表面,故該電性連接埠32可更為接近該導線口16,使該電源接線40更容易穿伸通過該導線口16,以便更進一步提升該電源接線40之組裝便利性。Referring to FIGS. 8 and 9, another structure of the substrate 30b is disclosed. The bonding end 21 of the wire fixing portion 20' is preferably located on the reference line (L), and the position of the wire fixing portion 20' is matched. Preferably, the outer periphery of the substrate 30b can form a convex portion 33 facing the wire opening 16 of the frame 10, and the convex portion 33 is also located at the reference line (L); in addition, the convex portion 33 can be combined The wire fixing portion 20' is formed on the surface of the convex portion 33. Therefore, by using the convex portion 33 of the substrate 30b, the electrical connection 32 of the substrate 30b can be located outside the rotation range of the permanent magnet 512 of the fan wheel 50, and more importantly, when the convex portion 33 is combined. After the wiring fixing portion 20', due to the electrical connection 埠 32 shape The surface of the convex portion 33 is formed, so that the electrical connection port 32 can be closer to the wire opening 16 so that the power connection wire 40 can be easily penetrated through the wire opening 16 to further improve the assembly of the power connection 40. Sex.
如上所述,本發明風扇確實可利用該接線固定部20’之結合端21對應連接該導線口16的結構設計,用以改善習知具有肋條(或靜葉)之風扇結構所具有之電源接線安裝不易的問題,使該接線固定部20’可更為接近該導線口16,確保該電源接線40可經由該接線固定部20’直接穿伸通過該導線口16,以有效提升該電源接線40之組裝便利性。As described above, the fan of the present invention can utilize the structural design of the connecting end 21 of the wire fixing portion 20' to connect the wire opening 16 to improve the power wiring of the conventional fan structure having ribs (or vanes). The problem of the installation is not easy, so that the wire fixing portion 20 ′ can be closer to the wire opening 16 , and the power wire 40 can be directly passed through the wire opening 16 through the wire fixing portion 20 ′ to effectively lift the power wire 40 . Assembly convenience.
