Description
本發明係有關一種踩踏曲柄技術,尤指一種人力車之可增力踩踏曲柄裝置。The present invention relates to a crank pedal technology, especially a pedal crank device of a rickshaw.
現今人們為了身體的健康或為了減少有害氣體和碳的排放量,大都會善用一部分的時間來進行,如慢跑、步行或騎乘自行車等運動,其中騎乘自行車由於具備有短、中程的旅遊效果,因此更可讓騎乘者的身、心、靈獲得最佳的舒緩,且在各縣市大量且廣設的自行車專用道下,騎乘自行車顯然已成為全民最熱衷的活動項目之一。Nowadays, people mostly spend part of their time for physical health or to reduce harmful gas and carbon emissions, such as jogging, walking or cycling. Among them, cycling has short and medium-range The tourism effect, so it can make the body, mind, and spirit of the rider get the best relief, and under the large and wide bicycle lanes in various counties and cities, biking has obviously become one of the most popular activities of the whole people. One.
習知自行車的曲柄為一固定長度的桿體,用以連接腳踏板與自行車的中心軸,自行車在運作過程中是透過使用者踩踏腳踏板,使腳踏板以中軸為旋轉中心進行以曲柄長度為半徑的圓周運動,並帶動自行車的驅動裝置如齒盤、鏈條等元件,進而使自行車前進。The crank of a conventional bicycle is a rod with a fixed length, which is used to connect the pedals to the central axis of the bicycle. During the operation of the bicycle, the user steps on the pedals so that the pedals rotate around the central axis. The length of the crank is the circular movement of the radius, and drives the bicycle driving device such as chainring, chain and other components to make the bicycle move forward.
現存廣泛應用在自行車的踩踏曲柄裝置,並不能夠在腳踏板旋轉至需要的施力處時,伸長其曲柄進而增加力臂的長度,因此無法達成增加力矩的效果。或許有些是採用曲柄能夠伸縮的特性做設計,惟此等伸縮曲柄的設計因不符合人體工學,無法以規律且慣性的做一圓周運動,實質上為一費力設計,其不僅結構複雜且易導致使用者疲勞的踩踏曲柄裝置。The existing pedal crank devices widely used in bicycles cannot extend the crank of the pedal to increase the length of the lever arm when the pedal is rotated to the required force. Therefore, the effect of increasing the torque cannot be achieved. Perhaps some are designed with the feature that the crank can be stretched, but the design of these stretched cranks is not ergonomic, and cannot make a regular and inertial circular motion. It is essentially a laborious design. It is not only complex in structure but also easy Stepping on the crank device that causes fatigue of the user.
有鑑於此,本發明人遂針對上述現有技術的缺失,特潛心研究並配合學理的運用,盡力解決上述之問題點,即成為本發明人改良之目標。In view of this, the inventor of the present invention focused on the above-mentioned shortcomings of the prior art, and made great efforts to solve the above-mentioned problems, which became the goal of the present inventor's improvement.
本發明之一目的,在於提供一種人力車之可增力踩踏曲柄裝置,其係透過加大施力臂的長度來增加力矩,不僅結構簡單且能夠以圓周運動方式達成穩定傳動。One of the objectives of the present invention is to provide an increased pedaling crank device for a rickshaw, which increases the torque by increasing the length of the applying arm, which is not only simple in structure but also capable of achieving stable transmission in a circular motion.
為了達成上述之目的,本發明係提供一種人力車之可增力踩踏曲柄裝置,包括一曲柄機構、複數滾珠及一增力旋臂,該曲柄機構包括一曲柄、設置在該曲柄之一端的一軸端齒輪及設置在該曲柄之另一端的一踏板端齒輪,在該曲柄設有與該軸端齒輪和該踏板端齒輪相通的一容珠通道;各該滾珠係彼此相互抵貼接觸,其中一部份的各該滾珠係與該軸端齒輪咬合傳動,另一部份的各該滾珠係與該踏板端齒輪咬合傳動,其餘的各該滾珠則分別容置在該容珠通道中;該增力旋臂的一端連接在該踏板端齒輪。In order to achieve the above objective, the present invention provides a rickshaw pedaling crank device, which includes a crank mechanism, a plurality of balls and a force booster arm. The crank mechanism includes a crank and a shaft end arranged at one end of the crank The gear and a pedal end gear arranged at the other end of the crank. The crank is provided with a ball-receiving channel communicating with the shaft end gear and the pedal end gear; each of the ball systems abuts and contacts each other, one of which Each of the balls is engaged with the shaft end gear for transmission, the other part of the balls is engaged with the pedal end gear for transmission, and the remaining balls are respectively accommodated in the ball-accommodating channel; the force increasing One end of the swing arm is connected to the pedal end gear.
本發明還具有以下功效,藉助各滾珠之間的相互抵靠,不管是做正向或反向的傳動皆沒有間隙產生,更加地提昇傳動效能和定位的精準度。透過增力旋臂呈一弧形設計,可避免與前輪在轉彎過程中的碰觸。利用各套接槽和各插塊的穿接結合,藉以有效地防止增力旋臂因長時間的運作而產生彎曲變形或扳離等不良情形。踩踏腳踏板讓曲柄做圓周運動的過程中,完全沒有上、下死點的問題和頓挫等傳動不良情況。The present invention also has the following effects. By virtue of the mutual abutment between the balls, no gap is generated whether it is a forward or reverse transmission, and the transmission efficiency and positioning accuracy are further improved. The arc-shaped design of the booster arm can avoid contact with the front wheel during turning. Utilizing the through connection of the socket grooves and the insert blocks, it can effectively prevent bad situations such as bending deformation or pulling apart of the force booster arm due to long-term operation. In the process of stepping on the pedal to make the crank make a circular motion, there is no problem of top and bottom dead center and poor transmission such as frustration.
