Abstract
Description
本發明係關於一種集電滑環結構,集電滑環的電刷單元具有自由端分岔形成複數電刷絲,能減少滑環跳動時產生跳針的機會。The invention relates to a collector slip ring structure. The brush unit of the collector slip ring has a free end bifurcated to form a plurality of brush wires, which can reduce the chance of needle skipping when the slip ring bounces.
集電環和電刷的配合可以應用在要求連續旋轉的同時,又需要傳輸電源及/或電子信號的電路系統中,避免導線在旋轉過程中造成扭傷。由於電刷必須要持續接觸金屬環以確保電源及/或電子信號的傳遞,其強度必須維持在一定的水準。此外,若使用金屬絲作為電刷,由於其接觸壓力輕、易磨損、跳針,會導致傳輸信號輸出不穩等現象。The combination of the slip ring and the brush can be used in a circuit system that requires continuous rotation and transmission of power and/or electronic signals to avoid spraining of the wires during rotation. Since the brushes must be in constant contact with the metal ring to ensure the transmission of power and/or electrical signals, their strength must be maintained at a certain level. In addition, if a metal wire is used as a brush, due to its light contact pressure, easy wear, and needle skipping, it will lead to unstable transmission signal output and other phenomena.
本發明提供一種集電滑環結構,包含一轉子模組以及一電刷模組,其特徵在於,該電刷模組具有複數個電刷單元呈間隔排列,每一該電刷單元具有一固定段以及二自由段延伸自該固定段的相對二端,每一該自由段從遠離該固定段的一端延伸形成複數個電刷絲,該等電刷絲具有筆直的一接觸區域電性連接該轉子模組。藉此,複數個電刷絲能提供較多電性連接的區域,避免其中一個電刷絲受灰塵干擾而產生斷訊的情況,而延長電刷結構的使用壽命。The present invention provides a collector slip ring structure, comprising a rotor module and a brush module, characterized in that the brush module has a plurality of brush units arranged at intervals, and each of the brush units has a fixed A segment and two free segments extend from opposite ends of the fixed segment, each of the free segments extends from one end away from the fixed segment to form a plurality of brush wires, and the brush wires have a straight contact area to electrically connect the Rotor module. Thereby, a plurality of brush wires can provide more areas of electrical connection, avoid the situation that one of the brush wires is interrupted by dust interference, and prolong the service life of the brush structure.
進一步地,轉子模組為複數個金屬滑環與複數個絕緣環沿著一虛擬軸向交互套設,據此,可以同時或分別對金屬滑環或絕緣環的寬度作微調,而對應需求製備集電滑環結構,使製程更加靈活。Further, the rotor module is a plurality of metal slip rings and a plurality of insulating rings alternately sleeved along a virtual axis, according to which, the width of the metal slip rings or the insulating rings can be fine-tuned at the same time or separately, and the corresponding requirements can be prepared. The collector slip ring structure makes the process more flexible.
為了清楚說明本發明之具體實施方式、構造及所達成之效果,配合圖示說明如下:In order to clearly illustrate the specific embodiments, structures and effects of the present invention, the following descriptions are provided in conjunction with the illustrations:
請參閱圖1至圖4,繪示集電滑環之各元件之間的對應關係,集電滑環100包含電刷模組20以及轉子模組40,電刷模組20拆分為上下兩個且分別安裝於外殼21,22,再將兩側的電刷模組20組裝於轉子模組40。Please refer to FIG. 1 to FIG. 4 , which illustrate the correspondence between the components of the collector slip ring. The
電刷模組20包含複數個電刷單元10呈間隔排列,以及基座18使複數個電刷單元10定位。電刷單元10概呈ㄇ狀,具有一固定段11以及二自由段13延伸自該固定段11的相對二端,固定段11以及二自由段13之間形成圓角的折角12。基座18至少包覆電刷單元10的固定段11相對二端,裸露電刷單元10的固定段11以及二自由段13之間的二折角12,進一步地,基座18裸露電刷單元10的固定段11中間部分,以分別電性連接導線30,使該等導線30亦位於同一平面,因此,導線30更容易堆疊於基座的一側,減少整體的尺寸。基座18可以使該等電刷單元10的間隔距離相同或不同,以對應轉子模組40的金屬滑環42的位置,而基座18裸露折角12時可以維持電刷單元10的應力。The
轉子模組40包含複數個絕緣環41與複數個金屬滑環42延著一虛擬軸向交互套設,該等金屬滑環42的內部還個別電性連接導線45,複數導線45集中於轉子模組40一端且延伸至轉子模組40外部,導線45再透過嵌件埋設成形,以同時定位絕緣環41與金屬滑環42,且同時形成轉子模組40的軸心50。The
因此,該等絕緣環41用來定義金屬滑環42的位置,使電刷模組20中的每一個電刷單元10都能夠對應地安裝在一個金屬滑環42上,使電刷單元10的電刷絲15接觸金屬滑環42。此外,透過將絕緣環41的寬度極小化,連帶地使金屬滑環42的寬度極大化,以及增加電刷絲15的寬度,也可以增加金屬滑環42與電刷絲15的接觸機會。此外,也可以微調金屬滑環42寬度,以提升金屬滑環42對電壓或電流的耐受性。此種轉子模組40的配置方式可以進一步微調金屬滑環42的寬度與金屬滑環42彼此的間隔距離,再透過埋入射出定位,使製程更加靈活。Therefore, the
於本實施態樣中,電刷單元10的每一個自由段13由固定段11的一端筆直地向外延伸,從自由段13的中間部分分岔形成二電刷絲15,電刷絲15的末端設有向外(遠離金屬滑環)的一折彎腳16,據此,折角12和折彎腳16可以提供適當的應力使自由段13朝向滑環。In this embodiment, each
進一步說明,電刷單元10的每一自由段13具有連接部份14一端連接折角12、以及二電刷絲15自該連接部份14另一端延伸而形成,每一電刷絲15具有一筆直部份定義為懸空區域151鄰近連接部份14、以及接觸區域152鄰近折彎腳16。據此,自由段13的連接部份14可以提供適當應力,使電刷絲15的接觸區域152能具有適當的彈力,以維持接觸金屬滑環42的狀態,減少跳針。此外,二電刷絲15的接觸區域152是個別地與一個金屬滑環42接觸,能提供較多電性連接的區域,避免其中一個接觸區域152受灰塵干擾而產生斷訊的情況,也能延長電刷單元10的使用壽命,在維持電性連接的前提下,一個連接部份14也可以分岔形成三個以上的電刷絲15。Further description, each
於本實施態樣中,自由段13的連接部份14、電刷絲15的懸空區域151、電刷絲15的接觸區域152的長度L大致上相同,然而,連接部份14與電刷絲15的長度比可以介於2:3至1:4(即1:1.5至1:4)之間,電刷絲15的懸空區域151與電刷絲15的接觸區域152的長度比介於5:4至5:6(即1:0.8至1:1.2)之間,也可以維持類似的應力,使電刷絲15服貼於滑環。In this embodiment, the length L of the
於本實施態樣中,電刷單元10的固定段11、自由段13略呈厚度均一的平板,自由段13的連接部份14的寬度較寬,可以在折角12的彎曲程度較小的情況下維持適當張力,也使自由端13在金屬滑環運行時不易形變。電刷絲15亦呈現平板狀,且相較於連接部份14具有較小寬度,以提升其機械特性,平板狀電刷絲15也可以與金屬滑環42產生線性接觸,以提高接觸的區域。然而,也可以透過調整電刷絲15的寬度,或使電刷絲的斷面概呈圓形,而獲得所需的機械特性。In this embodiment, the
透過上述之電刷模組20與轉子模組40的結構設置,可以使電刷單元10與金屬滑環42的結構依據位置或應力對應調整,使集電滑環100具有客製化的優勢。Through the above-mentioned structural arrangement of the
請參閱圖5,繪示集電滑環的組裝示意圖,在電刷單元10的電刷絲15的接觸區域152的中間段(約接觸區域152長度L的一半),為實際接觸金屬滑環42的接觸區域152,該接觸區域152可以透過調整折角12與折彎腳16的彎曲程度、自由段13的連接部份14或電刷絲15的寬度、電刷絲15的總長度,來維持對應的應力與接觸區域152,而更符合使用需求。Please refer to FIG. 5 , which is a schematic diagram of the assembly of the collector slip ring.
