按,基於環保與騎乘舒適的需求,故市面上具有各式電助自行車,而採踏扭力控制則為其主要的電助控制方式之一。 According to the needs of environmental protection and riding comfort, there are various electric bicycles on the market, and pedal torque control is one of the main electric bicycle control methods.
為提升於騎乘電助自行車時之輸出動力的穩定性,及於踩踏時之舒適性,具採踏扭力檢知裝置的電助腳踏車,每圈360度,均應有一對應腳踏曲柄於每一旋轉角度之理想扭力曲線值,而理想中之電助控制,則在於控制所提 供的電助扭力,使騎士在騎乘電動車時的腳踏扭力與理想扭力曲線值相同;但目前市面上尚未發現有滿足上述理想條件的電助腳踏車;現有的,多數都只有一對位置感測器,在配合計時器與訊號處理單元後,計算出腳踏曲柄軸的轉速與旋轉角度,但無以設定該旋轉角度之原點,並令腳踏曲柄軸每轉一圈時,其旋轉角度均可以重新校準;因此,無以提供精確的電助扭力,所提供的電助扭力往往只是將量得的扭力值乘以1或小於1的分數,再加以調整。 In order to improve the stability of the output power when riding an electric bicycle and the comfort when pedaling, an electric bicycle with a pedal torque detection device should have a corresponding pedal crank for each 360-degree circle. The ideal torque curve value of a rotation angle, and the ideal electric-assisted control lies in the control proposed The electric-assisted torque provided by the rider makes the rider’s pedal torque the same as the ideal torque curve value when riding an electric bicycle; however, no electric-assisted bicycles that meet the above ideal conditions have been found on the market; most of the existing ones have only one pair of positions The sensor, after cooperating with the timer and the signal processing unit, calculates the rotation speed and rotation angle of the pedal crank shaft, but it cannot set the origin of the rotation angle, and makes the pedal crank shaft turn one revolution, its The angle of rotation can be recalibrated; therefore, it is impossible to provide precise electric-assisted torque, and the provided electric-assisted torque is often only adjusted by multiplying the measured torque value by 1 or a fraction less than 1.
就扭矩之量測而言,習知提供一種概如我國發明專利證書第I604992號之「利用因推、拉力造成被量測體產生變形訊號之應變檢測器的配置方法及裝置」其係藉由將應變檢測器設置於車架,藉以量測其拉力或推力數據,不會造成輔助馬達運轉時對該應變檢測器產生反饋訊號,透過乘騎者施予助動車推、拉力時,令其產生變形現象,進而量測其變化差訊號,並以該變形訊號即可控制輔助馬達施予助動車正比的助力;惟其主要係設置於車架上,其仍須對該車架之形狀及架構進行力學之分析運算,才能得出精確之扭矩,故其適用性仍具有一定限制。 As far as the measurement of torque is concerned, it is known to provide a method and device for configuring strain detectors that use push and pull forces to generate deformation signals from the measured object, which is similar to the Chinese invention patent certificate No. I604992. Set the strain detector on the frame to measure its pulling force or thrust data. It will not cause the feedback signal to the strain detector when the auxiliary motor is running. Deformation phenomenon, and then measure the change difference signal, and use the deformation signal to control the auxiliary motor to give a proportional boost to the scooter; but it is mainly installed on the frame, and it still needs to be carried out on the shape and structure of the frame The precise torque can only be obtained through the analysis and calculation of mechanics, so its applicability still has certain limitations.
習知另提供一種概如大陸專利授權公告第2441731Y號之「電動自行車的扭力感測裝置」,其主要係藉由於車架之座管設置扭力感測器,惟該扭力感測器主要係量測騎乘時,自行車之鏈條因踩踏扭力增加而上浮頂撐之扭力,其設置方式將使扭矩之量測具有高度雜訊,使難以有效應用於市場上。 It is known that another kind of "torque sensing device for electric bicycles" similar to the mainland patent authorization announcement No. 2441731Y is provided, mainly by setting a torque sensor on the seat tube of the frame, but the torque sensor mainly measures When measuring riding, the torque of the bicycle chain floating up and up due to the increase of the pedaling torque, the setting method will make the measurement of the torque highly noisy, making it difficult to effectively apply it to the market.
多數之踩踏力感測器,多數係被設置於中置馬達內部之曲柄軸、踏板或車架上,然而,其設置所量測扭矩之感測值將會具有諸多雜訊,因馬達電助扭力之提供、車身於移動時之震盪、使用者騎乘及踩踏之姿勢等,皆會影響扭矩感測器之感測值,其將導致影響扭矩量測之精確性,即使經過複雜之運 算處理雜訊,仍無法快速、準確且有效的分析其量測之扭矩,其將使電助扭力之提供產生不穩定之情事,有影響騎乘安全及舒適性的疑慮。 Most of the pedaling force sensors are installed on the crankshaft, pedal or frame inside the mid-mounted motor. However, the sensing value of the measured torque will have a lot of noise, because the motor is electrically assisted The provision of torque, the vibration of the body when moving, the user's riding and pedaling posture, etc., will all affect the sensing value of the torque sensor, which will affect the accuracy of torque measurement, even after complex movements Even if the noise is dealt with, it is still impossible to quickly, accurately and effectively analyze the measured torque, which will cause instability in the provision of electric torque, which may affect riding safety and comfort.
此外,習知用以裝設中置馬達之殼體,多數者,係由兩個呈C字型之殼體相互樞接形成,而殼體於相對於其樞接處,係透過分別延伸設置一鎖固平面,並於該鎖固平面穿設穿孔,藉可透過螺絲貫穿於鎖固平面後,鎖固於螺帽,藉以將兩殼體予以迫緊而定位中置馬達;然其設置方式,首先就殼體間之樞接而言,其通常係透過螺栓而達致其樞接,惟其設置將會產生背隙,故於騎乘自行車時,將會令殼體間,或殼體與螺栓間產生震動,其將會產生雜訊;此外,就其鎖固平面、螺絲與其螺帽之設置,其同樣將因自行車之騎乘而有受震動之情事,不僅如此,其震動亦將會使螺帽鬆脫,使更增加雜訊的產生,使大幅影響扭力之偵測,前述者,皆將使前述設置之踩踏力感測器所量測之踩踏扭力具有一定偏差,使中置馬達因應踩踏力所給進之電助力亦不穩定,同樣具有前述影響騎乘安全及舒適性的疑慮之缺失。 In addition, it is known that most of the casings used to install the central motor are formed by two C-shaped casings that are pivotally connected to each other, and the casings are respectively extended through the pivot joints. A locking plane, and a perforation is set on the locking plane, through which the screw can pass through the locking plane and be locked to the nut, so as to tighten the two housings and position the central motor; however, the setting method , first of all, as far as the pivotal connection between the shells is concerned, it is usually achieved through bolts, but its setting will produce a backlash, so when riding a bicycle, it will make the shells, or the shell and the shell and If there is vibration between the bolts, it will generate noise; in addition, regarding the setting of the locking plane, the screw and its nut, it will also be subject to vibration due to the riding of the bicycle, not only that, but the vibration will also Loosening the nut will increase the generation of noise and greatly affect the detection of torque. All of the above will cause a certain deviation in the pedaling torque measured by the pedaling force sensor installed above, which will make the mid-mounted motor The electric assist given in response to the pedaling force is also unstable, and it also has the aforementioned lack of doubts affecting riding safety and comfort.
有鑑於此,吾等發明人乃潛心進一步研究電助自行車,並著手進行研發及改良,期以一較佳發明以解決上述問題,且在經過不斷試驗及修改後而有本發明之問世。 In view of this, our inventors are concentrating on further research on electric bicycles, and embark on research and development and improvement, hoping to solve the above problems with a better invention, and the present invention comes out after continuous testing and modification.
爰是,本發明之目的係為解決前述問題,為達致以上目的,本發明提供一種電助自行車之踩踏力感測裝置,本發明係變形量感測器(如:應變規等)及中置馬達焊接在車架,而與馬達以螺絲直接垂直對接的連接殼的整合。變形量感測器可被設置在中置馬達的內外殼、或連接殼或自行車之座管底部段 上。中置馬達殼體與連接殼上均設有可令兩者以螺絲緊密垂直對接的孔洞,當螺絲鎖固後,馬達殼體與連接殼的接觸面將緊密的接合,並將兩者緊密的結合成一體。變形量感測器在於量測騎士之腳踩踏力。此腳踏力經由自行車之腳踏軸,傳遞到馬達殼體、連接殼或自行車之座管,並產生變形。變形量感測器在取得變形量後,可推算出騎士各腳的踩踏力;其優點在於,此量測騎乘所產生踩踏力,不易有雜訊,使可易於準確計算踩踏力;此馬達殼體與連接殼成為一體的緊密結合,一方面可避免一般以螺絲橫向掛接的結合,在踩踏時因間隙所產生的各種雜訊,進而量取得精確可用的踩踏力。此外,馬達內的熱亦可經由緊密結合的接觸面傳遞到整個車架,因而大幅提高整體的散熱及馬達效能;此外,本發明之設置並具有易於安裝的特性,讓變形量感測器可易於裝設在各式種類之電助自行車之座管或殼體處,無須對電助自行車進行大幅度改裝,藉可有效降低設置成本;此外,配合殼體之設計,使殼體及中置馬達於定位時不因震動而產生雜訊,藉可使本發明對於踩踏力之感測更加精準,以令訊號處理單元可依據純淨的踩踏力而讓中置馬達補償精確的電助扭力,以提升於騎乘時之舒適性及於輸出動力之穩定性者,且其設置亦可將鎖固之處隱藏,以提升整體之視覺美感者。 Yes, the purpose of the present invention is to solve the aforementioned problems.

本發明之變形量感測器1,除可如前述設置於座管21之外,在另一實施例中,如第4圖至第9圖所示,亦可設置於中置馬達4外部設置之一馬達殼
6之殼體61上,亦可設置於在中置馬達4及殼體61所配置之一連接殼62上,且中置馬達4連同馬達殼6設置於多通管內,或如本實施例第8圖所示者,將自行車2之車架24及座管21直接連結於馬達殼6,而中置馬達4則係容置於該馬達殼6內,以受馬達殼6防護,藉此,使用者騎乘時所產生之踩踏力,亦可作用於馬達殼6而令其產生型變,故藉由將變形量感測器1如第6、8、9圖所示,分別或同時設置於殼體61及連接殼62之內壁面或外表面,皆使可量測作用於馬達殼6之踩踏力,藉可如前述,不易產生雜訊,藉可精確量測踩踏力;此外,該中置馬達4之殼體61與連接殼62上均設有可令兩者緊密且垂直對接之孔洞,藉以於透過一鎖接元件鎖固於孔洞時,該殼體61與該連接殼62的接觸面將緊密的接合,並將兩者緊密的結合成一體;因此,於使用者騎乘該自行車時,腳踏力經由自行車之腳踏軸,傳遞到殼體61、連接殼62或自行車之座管21,並產生變形量,而該變形量感測器係可據以量測其變形量,變形量感測器1在取得變形量後,訊號處理單元5即可推算出騎士各腳的踩踏力。透過中置馬達4馬達殼6與連接殼62間的緊密結合,一方面可避免一般以橫向掛接的結合,在踩踏時因間隙所產生的各種雜訊,進而量取得精確可用的踩踏力。此外,馬達內的熱亦可經由緊密結合的接觸面傳遞到整個車架,因而大幅提高整體的散熱及馬達效能。
The
綜前所述者,可知將變形量感測器1,設置於座管21或馬達殼6可簡易且有效的量測踩踏力,且不易受雜訊所干擾,藉可無須對變形量感測器1之感測值進行複雜之分析運算,即可迅速且精準的偵測踩踏力,而較佳者,為令安裝中置馬達4時,其於騎乘過程中可確實被定位,而不致其產生震動而致影響設置於座管21或馬達殼6之變形量感測器1的感測,故較佳者,如第4圖至第10圖所示,馬達殼6係包含殼體61及連接殼62,而變形量感測器1係可設置於馬達殼6
或連接殼62之外表面或內表面,其中,該殼體61設有一容置部611,該容置部611係用以承接容置該中置馬達4;該殼體61沿其徑向方向設置有至少一定位部612,且所述定位部612係設有至少一所述孔洞613;該連接殼62係由徑向方向對應蓋設於該殼體61,該連接殼62於對應所述定位部612處具有一抵接部621,所述抵接部621凹設有一定位孔622,其係可如第4圖所示,由抵接部621軸向凹設,或可如第5圖所示,由抵接部621之側向方向而凹設者,而所述定位孔622內之底端,於對應於所述孔洞613處,亦設有對應之孔洞623,以與該殼體61之所述孔洞613相互連通,該定位孔622內容置有對應於所述孔洞之固接元件63;而所述鎖接元件64係分別對應貫穿所述孔洞613、623,並對應定位於對應之所述固接元件63者;藉此,透過鎖接元件64對於固接元件63之定位,藉中置馬達4可受殼體61及連接殼62間之迫緊而定位之;為了具讓人從連接殼上看不到鎖接元件64或固接元件63的時尚感,連接殼62上與殼體61對接的孔洞622不貫穿抵接部621,而係在連接殼62上與孔洞613相交且垂直的方位挖出所述孔洞623,以置入固接元件63。
In summary, it can be seen that the
就孔洞613及固接元件63之配置而言,在一較佳之實施例中,所述固接元件63可為螺帽,而所述鎖接元件64為對應之螺絲,且固接元件63係可為非圓形之幾何形狀,如:六角形之螺帽,並於其側緣之至少一端面係恰可對應於定位孔622之內壁面,使固接元件63於旋轉方向上受定位孔622限位,藉以令鎖接元件64鎖固於固接元件63時不會轉動,且亦將不易受晃動而致脫落,藉可確實將殼體61、連接殼62及中置馬達4予以穩固定位而不受力而有鬆脫或晃動之情事,藉使其不會產生震動之雜訊,故令變形量感測器1可精確量測踩踏力;此外,藉其設置,亦可將固接元件63隱藏於固接孔613內,而當鎖接元件64係相
對位於自行車底端時,使於一般視覺方向無法直接觀及固接元件63及鎖接元件64,故可提升馬達殼6整體之視覺美感。
As far as the configuration of the
而就馬達殼6整體之材質而言,其係可為硬質或不易磨損之材質製成,藉以有效迫緊中置馬達4,並可令固接孔613可確實限位固接元件63,而不因鎖接元件64之鎖固而產生崩牙之情事,且於鎖接元件64鎖固於固接元件63時,其之間亦可設置有一墊片,以防止對於殼體61或連接殼62之磨損。
In terms of the overall material of the
而就殼體61及連接殼62之形狀配置而言,在一實施例中,殼體61係可呈環形設置或弧形設置,而連接殼62係呈弧形設置,而當如本實施例所示,當殼體61呈環形設置時,可知悉者,為可予迫緊中置馬達4,故殼體61將具有可塑性,藉以令連接殼62如前述者定位於殼體61時,將可迫壓殼體61而迫緊定位中置馬達4;而當殼體61及連接殼62皆呈弧形設置時,可知悉者,如前述鎖接元件64及固接元件63間之定位,將可使殼體61及連接殼62迫緊夾掣定位中置馬達4,並且,中置馬達4內的熱可經由緊密結合的接觸面傳遞到整個車架,因而大幅提高整體的散熱及中置馬達4效能。此外,一旦在殼體61或連接殼62上裝置變形量感測器1時,它可避免在踩踏時因間隙所產生的各種雜訊,進而量取得精確可用的訊號。
As far as the shape configuration of the
另就馬達殼6對於中置馬達4之軸向定位方式而言,在一實施例中,殼體61係可直接的於其軸向成型對應中置馬達4輪廓之壁面,而在其他實施例中,亦可如本實施例所示者,透過於該馬達殼6於軸向一端係形成有一開口65,且該馬達殼6在對應該開口65之側緣處更設有至少一組接部651;一蓋體66,其設有對應於所述組接部651之結合部661,該蓋體66係對應蓋合於該開口65,且所述結合部661係對應組接於該組接部651,在一實施例中,所述結合部661為 穿孔,且更包含至少一定位部件67,其係分別貫穿於所述結合部661以對應定位於所述組接部651,故可知悉者,定位部件67係可為螺絲或對應組接於組接部651之定位銷;藉此,即可軸向定位並防護中置馬達4,使防止中置馬達4受外界之水分及髒污而影響其運作。 In addition, in terms of the axial positioning method of the motor housing 6 for the mid-mounted motor 4, in one embodiment, the casing 61 can directly form a wall surface corresponding to the contour of the mid-mounted motor 4 in its axial direction, while in other embodiments In this embodiment, as shown in this embodiment, an opening 65 is formed at one end of the motor housing 6 in the axial direction, and the motor housing 6 is further provided with at least one connecting portion at the side edge corresponding to the opening 65 651; a cover body 66, which is provided with a joint portion 661 corresponding to the assembly portion 651, the cover body 66 is correspondingly covered on the opening 65, and the joint portion 661 is correspondingly assembled on the assembly joint part 651, in one embodiment, the joint part 661 is perforated, and further includes at least one positioning component 67, which respectively penetrates through the joint portion 661 to be correspondingly positioned on the assembly portion 651, so it can be known that the positioning component 67 can be screwed or correspondingly assembled in the assembly The locating pin of the connection part 651; thereby, the central motor 4 can be axially positioned and protected, so as to prevent the central motor 4 from being affected by external moisture and dirt from affecting its operation.
