按，現代自行車的車架幾何及驅動機構的基本架構及概念應均係源自於文藝復興時期達文西(1452年4月15日生-1519年5月2日歿)的研究及設計，曾參觀過達文西大展的人，應對他的許多設計都留有深刻的印象，其中，尤其是他在1490年留下的自行車機械圖手稿，其上在當時就已繪製有齒盤及鏈條的設計；嗣，在1600年間，英國教堂的窗戶上亦曾經留下有以馬為造型的概念自行車圖騰；然而，自行車機械的真正萌芽期間應發生在1791年至1838年的47年間，其中，在1791年間，有位名叫「席夫洛」的法國工匠曾以木頭製造了一種動物造型且前後共有兩個輪子的腳撥式車子，當時，它被稱之為「塞萊里費爾自行車」(Celerifere)；後來，在1817年間，有位名叫「德萊司」的德國男爵，為了巡察皇家花園的需要，而發明了一種由木製車體與鐵製車輪外加裝操控裝置所組合而成的「休閒鐵馬」，該「休閒鐵馬」的運作方式係騎乘者必需以雙腳在地上蹬踩或推撥地面，始能令該「休閒鐵馬」持續地前進；因此，當時的英國人乃將它稱之為「hobby horse」，此款車從此成為法國、德國及英國貴族社會的新寵；直到1819年間，法國人始發明了簡易的雙輪車；隨後，在1820年間，德國繼而開發出世界第一台有龍頭把手，可供騎乘者以雙手握持操控的雙輪自行車。自行車機械的轉變期則係發生在1839年至1876年的37年間，這段期間拜工業革命之賜，冶金技術的進步使得自行車的車體逐漸能以金屬材料製作，另，伴隨著各項機械技術的快速發展，亦使得自行車逐漸能以機械傳動技術取代騎乘者以腳蹬踩或推撥地面的運作模式，此時，雖然自行車的車架幾何及傳動機構的基本架構已日趨成熟，但是，市面上的各式自行車款一般仍是以前輪大、後輪小的車款較多，且在當時的都會區中，自行車 已很普及化，甚至，有些歐洲城市更因此而在都會區中設置了自行車專用道。 According to the press, the frame geometry of modern bicycles and the basic structure and concept of the driving mechanism should all be derived from the research and design of the Renaissance Da Vinci (born April 15, 1452-May 2, 1919), visited Those who have passed the Da Vinci exhibition have been deeply impressed with many of his designs. Among them, especially the manuscript of the mechanical drawings of bicycles he left in 1490, the design of the chainring and chain was already drawn on it at that time; Heir, in 1600, there was also a concept bicycle totem in the shape of a horse on the window of the English church; however, the real budding period of bicycle machinery should have occurred between 1791 and 1838 in 47 years, of which, in 1791 , A French craftsman named "Schifflow" once made an animal-shaped foot-pedaled car with two wheels on the front and back. At that time, it was called "Celerifere bicycle" (Celerifere bicycle) ); Later, in 1817, a German baron named "Dress", in order to inspect the Royal Garden, invented a combination of a wooden car body and iron wheels with additional control devices. "Leisure Iron Horse", the operation mode of the "Leisure Iron Horse" is that the rider must pedal on the ground with his feet or push the ground, so that the "Leisure Iron Horse" can continue to move forward; therefore, the British at that time were It is called "hobby horse", and this car has since become the new favorite of the aristocratic society of France, Germany and Britain; until 1819, the French began to invent simple two-wheeled vehicles; then, in 1820, Germany then developed the world The first is a two-wheeled bicycle with a faucet handle for riders to hold with both hands. The transformation period of bicycle machinery occurred in the 37 years from 1839 to 1876. During this period, thanks to the industrial revolution, the progress of metallurgical technology made the bicycle body gradually made of metal materials. In addition, it was accompanied by various machinery The rapid development of technology has also made it possible for bicycles to gradually replace the rider's operation mode of pedaling or pushing the ground with mechanical transmission technology. At this time, although the bicycle frame geometry and the basic structure of the transmission mechanism have become more mature, but , The various types of bicycles on the market are generally still the ones with large front wheels and small rear wheels, and in the metropolitan area at that time, bicycles It has become very popular, and even some European cities have set up bicycle lanes in metropolitan areas.
直到1839年間，英國蘇格蘭的一位名叫「麥米蘭」的鐵匠始研發製造出第一台能用腳踏板以槓桿原理驅動後輪轉動的兩輪自行車。1842年間，麥米蘭甚至騎著他所製作的兩輪自行車自蘇格蘭前往格拉斯哥，來回共計226公里，該輛自行車在其中一段65公里的路段中，其平均時速竟已能達到13公里，至此，騎乘者始能真正雙腳離地，而完全以機械傳動方式，驅動自行車奮力朝前邁進。 Until 1839, a blacksmith named "McMilan" in Scotland, England, developed and manufactured the first two-wheeled bicycle that could use the foot pedal to drive the rear wheel to rotate. In 1842, McMillan even drove from Scotland to Glasgow on a two-wheeled bicycle he made. The total speed was 226 kilometers. The bicycle was able to reach an average speed of 13 kilometers per hour in a section of 65 kilometers. The biker can really leave his feet off the ground, and completely uses mechanical transmission to drive the bicycle to stride forward.
後來，在1861年間，一家名叫「米尚」的法國馬車製造商構思出在該「休閒鐵馬」的前輪上安裝一曲柄及腳踏板，並將其稱之為「腳蹬雙輪車」，此即世界上第一部的前輪驅動自行車；嗣，在1866-67年間，他又構思且製造出前輪加大且經細部改良的車種，兩輪車從此大受歡迎且日益普及；直到1868年間，有一位法國人發明了第一輛利用鏈條傳動，以驅動後輪轉動的「安全型自行車」；這款「安全型自行車」不僅已具備了現今自行車車架幾何及傳動機構的基本雛型，亦因其成熟的車架幾何及傳動機構而激勵了周邊相關零件產業的發展，如：不斷進行研發及改良，從而在1869年間，完成且推出了幾項重大的發明成果，如：滾珠、軸承式輪轂、金屬幅條車輪、實心橡膠輪胎、飛輪、擋泥板及用控制操桿操控的四速傳動裝置...等；1869年間，英國更首先在車輪上使用雙排幅條來支撐輪框的結構；1870年間，英國更開發出世界第一台以木質材料製作的輪框，其外包覆有橡膠材料製作的輪胎。1876年間，法國更設計及開發出世界第一台前輪設有腳踏板與曲柄，後輪則設有煞車裝置的自行車。 Later, in 1861, a French carriage manufacturer named "Michan" conceived of installing a crank and foot pedal on the front wheel of the "leisure iron horse" and called it "pedal two-wheeled vehicle" , This is the world's first front-wheel drive bicycle; he, in 1866-67, he conceived and manufactured a model with enlarged front wheels and detailed improvements. The two-wheeled vehicle has been very popular and increasingly popular; until 1868 During the year, a Frenchman invented the first "safety bicycle" that used chain transmission to drive the rotation of the rear wheels; this "safety bicycle" not only has the basic prototype of the current bicycle frame geometry and transmission mechanism. It has also stimulated the development of peripheral related parts industry due to its mature frame geometry and transmission mechanism, such as: continuous research and development and improvement, so that in 1869, several major inventions were completed and launched, such as: ball, Bearing hubs, metal spoke wheels, solid rubber tires, flywheels, mudguards, and four-speed transmissions controlled by control levers...etc.; in 1869, the United Kingdom first used double-row spokes to support the wheels The structure of the wheel frame; in 1870, the United Kingdom developed the world's first wheel frame made of wood material, which was covered with rubber tires. In 1876, France also designed and developed the world's first bicycle with pedals and cranks on the front wheels and brakes on the rear wheels.
自1877年至1890年的18年間，乃自行車鏈條與鏈輪的應用及試驗期間，在這段期間內，鏈條驅動與前輪傳動概念的混合體逐漸建立，同時，加入了前後齒輪比的概念，使得大大的前輪因不切實際，而逐漸遭到淘汰且最終淪為被捨棄的命運；在1884年間，英國一位名叫H．J．Lawson的發明人思及在前後輪間安裝一腳踏板，並將此車命名為「Bicyclette」，此即，自行車英文名「Bicycle」的由來；嗣，在1885年間，「史達利」在英國推出了一名為「羅弗安全自行車」(Rover Safety bicycle)的車款，它是世界上第一台有鏈條及前叉避震器，且係由後輪傳動的自行車，此款車的前後輪直徑係完全相同，且其上所使用的鏈條傳動機構亦堪稱現代自行車上鏈條傳動機構的始祖；之後，在1888年間，「杜羅普」發明了充氣式輪胎以有效地克服了行駛在顛簸道路上的諸多缺點，充氣式內胎不僅具備避震效果還具有能大幅減少車輪滾動阻力的效果。自此，這輛車款乃在不斷改善的發展下，終於演化成為目前人人都能輕鬆騎乘及駕御其上的安全自行車，且令這款安全自行車不僅快速地席捲了當時的工業化社會，更在隨後的數百年間風靡了全世界的各個角落。自1890年起至1930年止的40年間，更是自行車功能展露頭角的多樣化時期，在這段期間裏，基於各種工業技術的不斷進步及日趨成熟，加上第一次世界大戰後藝術文化的蓬勃發展，自行車亦已隨之發展出載貨用自行車、軍用折疊自行車、女性騎乘專用車、競速跑車、舒適靠背自行車、無須鍊條自行車...等；其中，在1890年間，愛爾蘭更設計及製造了世界第一台有氣壓輪胎的自行車；在1904年間，法國陸軍則設計及製造出世界第一台折疊式自行車；在1905年間，英國更設計及製造出世界第一台消防用自行車。直到1914年，全世界開始流行在自行車上 安裝變速器。1935年間，英國設計及製造出世界第一台手動變速自行車。自1930年至1960年的30年間，登山自行車開始萌芽。自1960年起至1990年止的30年間，自行車車型的多樣化及輕量化已漸成趨勢，市場上於是出現了斜躺式自行車、BMX自行車、鋁合金自行車、登山專用自行車、避震自行車...等。1990年迄今，自行車已成為人們追求健康運動與休閒的工具，因而在自行車上加裝電子儀器，以便據以掌控或監測騎乘者的生理狀況及騎乘狀態，幾乎已成為購車者要求的基本配備。直到2005年起，電力輔助式自行車始更因充電電池產業的日趨穩定及成熟，而令電動自行車逐漸發展成引領時尚風潮的全新代步及休閒工具。 During the 18 years from 1877 to 1890, it was the period of application and testing of bicycle chains and sprockets. During this period, a mixture of chain drive and front wheel transmission concepts was gradually established. At the same time, the concept of front and rear gear ratios was added. As a result, the large front wheel was gradually eliminated due to impracticality and eventually fell into a forsaken fate; in 1884, a British name was H. J. The inventor of Lawson thought about installing a pedal between the front and rear wheels, and named the bike "Bicyclette", that is, the origin of the bicycle's English name "Bicyclette"; Si, in 1885, "Stanley" in the United Kingdom Introduced a "Rover Safety bicycle" (Rover Safety bicycle) model, it is the world's first chain and front fork shock absorber, and is driven by the rear wheel bike, this model of the front and rear The wheel diameter system is exactly the same, and the chain transmission mechanism used on it is also called the ancestor of the chain transmission mechanism on modern bicycles; later, in 1888, "Durope" invented pneumatic tires to effectively overcome the driving There are many shortcomings on bumpy roads. Inflatable inner tubes not only have the effect of shock absorption, but also have the effect of greatly reducing the rolling resistance of the wheels. Since then, this car has evolved into a safe bicycle that everyone can easily ride and control under the continuous improvement of the development. This safety bicycle not only quickly swept through the industrialized society at that time, In the following hundreds of years, it swept all corners of the world. During the 40 years from 1890 to 1930, it was a period of diversification in the emergence of bicycle functions. During this period, based on the continuous progress and maturity of various industrial technologies, plus the art culture after the First World War The vigorous development of bicycles has also led to the development of cargo bicycles, military folding bicycles, female riding special vehicles, racing sports cars, comfortable backrest bicycles, chain-free bicycles, etc.; among them, in 1890, Ireland designed more And manufactured the world's first bicycle with pneumatic tires; in 1904, the French Army designed and manufactured the world's first folding bicycle; in 1905, the United Kingdom also designed and manufactured the world's first firefighting bicycle. Until 1914, the world began to be popular on bicycles Install the transmission. In 1935, Britain designed and manufactured the world's first manually-shifted bicycle. During the 30 years from 1930 to 1960, mountain biking began to sprout. In the 30 years from 1960 to 1990, the diversification and weight reduction of bicycle models has gradually become a trend. There have been reclining bicycles, BMX bicycles, aluminum alloy bicycles, mountaineering bicycles, and shock-absorbing bicycles on the market. ..Wait. Since 1990, bicycles have become a tool for people to pursue healthy sports and leisure. Therefore, installing electronic instruments on the bicycles to control or monitor the physiological and riding status of the riders has almost become the basic requirement of car buyers. Equipped. Since 2005, electric-assisted bicycles have become more and more stable and mature due to the rechargeable battery industry, which has gradually developed electric bicycles into a new transportation and leisure tool that leads the fashion trend.
雖然，誠如前述，電動自行車已因充電電池產業的日趨穩定及成熟，而逐漸發展成為引領時尚風潮的全新交通工具，但是，無論相關產業界對現今電動自行車進行何種程度的改良及演進？它們仍完全需藉由其上所安裝既笨重又龐大的充電電池，儲備電力，且必需能隨時隨地充飽電力，始能在需要時，據以驅動其上所安裝的笨重電動馬達，帶動自行車輪轂轉動前進，如此，大量充電電池、電動馬達及充電設備的製作、使用、耗損及報銷，不僅對自然資源造成無止盡地消耗及浪費，亦經常會因充電設施的不敷供應及使用，而在電力耗盡或機電零件發生故障時，只能雙眼望著笨重且毫無動力的電動自行車，莫可奈何！有鑑於此，如何針對各式習知自行車或電動自行車上所存在之諸多缺失，進行改良，以針對各式習知自行車的動力系統，設計出一全新的自行車架構，不僅令該全新的自行車在規格上仍能沿襲著幾百年來所建構的最佳車架幾何及傳動機構等基本設計，使得騎乘者在任何狀況下，均能以最佳的操控姿勢輕鬆地駕御該全 新的自行車，尚令該全新的自行車能在不斷前進的過程中，有效地利用其前輪轂持續轉動的動能，自動產生加壓空氣(或壓縮空氣)，且將該加壓空氣蓄積及儲存至其車架內所設之一儲氣空間中，以源源不斷地供應其上所設之一動力轉換機構使用，令該動力轉換機構能持續地產生一輔助驅動力來驅動其後輪轂，從而令該後輪轂不僅能在傳統鏈輪傳動機構的帶動下正常轉動，尚能因該輔助驅動力持續且穩定地的供應，而令該後輪轂始終能更有力地向前轉動，以使騎乘者能在完全無需藉助電力及電動馬達的狀態下，輕鬆且省力地騎乘及操控該全新的自行車，此不僅為目前自行車設計及製造業界始終汲汲營營亟欲解決之一重要議題，亦為本發明在後續欲深入探討及解決之一重要課題。 Although, as mentioned above, electric bicycles have gradually developed into new vehicles leading the fashion trend due to the increasing stability and maturity of the rechargeable battery industry. However, regardless of the degree of improvement and evolution of the current electric bicycles by related industries? They still completely need to be equipped with heavy and bulky rechargeable batteries installed on them to reserve power, and must be able to recharge at any time and anywhere, so that they can drive the heavy electric motors installed on them to drive bicycles when needed. As the hub rotates forward, the production, use, loss and reimbursement of a large number of rechargeable batteries, electric motors and charging equipment not only cause endless consumption and waste of natural resources, but also often cause insufficient supply and use of charging facilities. But when the power is exhausted or the mechanical and electrical parts fail, you can only look at the heavy and unpowered electric bicycle, what can you do! In view of this, how to improve the many shortcomings of various conventional bicycles or electric bicycles to design a new bicycle structure for the power system of various conventional bicycles, not only to make the new bicycle The specifications can still follow the basic design of the best frame geometry and transmission mechanism constructed for hundreds of years, so that the rider can easily control the whole vehicle in the best control posture in any situation. The new bicycle allows the brand-new bicycle to effectively use the kinetic energy of its front wheel to continuously generate compressed air (or compressed air) during the process of continuous advancement, and accumulate and store the compressed air to In one of the air storage spaces provided in its frame, it is continuously supplied to one of the power conversion mechanisms provided on it, so that the power conversion mechanism can continuously generate an auxiliary driving force to drive its rear wheel hub, so that The rear wheel hub can not only rotate normally under the drive of the traditional sprocket transmission mechanism, but also because the auxiliary driving force is continuously and steadily supplied, the rear wheel hub can always rotate forward more vigorously, so that the rider It can easily and effortlessly ride and control the new bicycle without the help of electricity and electric motors. This is not only an important issue that the bicycle design and manufacturing industry has always been eager to solve, but also based on An important subject that the invention wants to discuss and solve in depth in the follow-up.
