M424298 五、新型說明： 【新型所屬之技術韻域】 [0001] 本創作係關於一種動力自行車，特指一種應用諧波減速 裝置為動力套件之雙諧波電動自行車。 【先前技術】 [0002] 隨著經濟社會的變遷，大眾運輸交通工具如飛機、汽機 車等之數量快速成長，進而石油能源的需求量亦相對提 高，導致國際間油價節節升高，且現今原油已有被過度 開採之虞，再加上碳排放量劇增，造成地球暖化效應進 而嚴重影響生態，因此國際間不約而同的發出警訊，再 者，近年來國人運動健身的風氣興起，能兼具節能減碳 及運動休閒的自行車，日前已在國内造成一股旋風，騎 乘自行車不僅是一種流行時尚的休閒活動，也是一種健 康積極的生活方式。 [0003] 自行車之主要概念為利用騎乘者的腳踏力量踩動齒盤並 連帶驅動後輪旋轉，進而作為前進的動力源，然而當使 用者於騎乘至具有斜度之上坡地形或者是需要騎乘一相 當遠的長途距離時，或可能發生腳力不足，亦或者是腳 力不勝負荷、過度疲勞而影響騎乘，尤其是對於老人家 、女性朋友或者幼童而言，腳力吃重的騎乘行程更可能 是一種障礙，而基於此考量，故遂有可選擇性以電力驅 動組件取代以腳踏轴驅動組件驅動行駛之電動自行車（電 動輔助自行車）的問世。 [0004] 現有技術中之電動自行車的電動驅動機（馬達、發動機等 )之轉速大多介於600rpm至1 500rpm，一般業界使用之減 表單编號A0101 第3頁/共19頁 M424298 速器僅能將轉速減少20倍至30倍，效果有眼，故一旦使 用者踩踏電動自行車上之踏板時，恐將無法跟隨踏板之 旋轉速度，而有造成意外傷害之危險，並且，一般業界 使用之減速器僅可將扭矩（扭力）轉變為每單位距離（公尺 )所產生能量功率為6牛頓米力，此時，一旦坡度超過15 度時，由電動自行車本身所輸出之動力便不足以爬升， 使用者必須大幅施加踩踏之力，以提供較大扭力給予電 動自行車爬升，於實際應用上有其不足之處，故綜觀前 所述，本創作之創作人思索並設計一種雙諧波動力自行 車，以期針對現有技術之缺失加以改善，進而增進產業 上之實施利用。 【新型内容】 [0005] 有鑒於前述之現有技術的不足點，本創作係設計一種具 備新穎性、進步性及產業利用性等專利要件之雙諧波動 力自行車，以期克服現有技術之難點。 [0006]

V. New Description: [New Technology Field] [0001] This creation is about a power bicycle, especially a dual harmonic electric bicycle using a harmonic reduction device as a power kit. [Prior Art] [0002] With the changes in the economy and society, the number of mass transit vehicles such as airplanes and steam locomotives has grown rapidly, and the demand for petroleum energy has increased relatively, resulting in an increase in international oil prices. Crude oil has been over-exploited, coupled with a sharp increase in carbon emissions, which has caused the global warming effect and thus seriously affected the ecology. Therefore, the international community has issued warnings. In addition, in recent years, the trend of Chinese people’s sports and fitness has risen. Bicycles with energy saving, carbon reduction and sports and leisure have caused a whirlwind in the country. Riding bicycles is not only a fashionable leisure activity, but also a healthy and active lifestyle. [0003] The main concept of the bicycle is to use the rider's foot force to step on the toothed disc and drive the rear wheel to rotate, which is used as a power source for advancement. However, when the user rides to a slope with a slope or It is necessary to ride a long distance of a long distance, or there may be insufficient foot force, or the load of the foot is too heavy, and the fatigue is affected, especially for the elderly, female friends or young children. The trip is more likely to be an obstacle, and based on this consideration, there is an option to replace the electric bicycle (power-assisted bicycle) driven by the pedal drive unit with an electric drive unit. [0004] The speed of the electric drive machine (motor, engine, etc.) of the electric bicycle in the prior art is mostly between 600 rpm and 1,500 rpm, and the general use of the form is reduced by the form number A0101, page 3/19 pages of M424298. The speed is reduced by 20 times to 30 times, and the effect is obvious. Therefore, once the user steps on the pedal on the electric bicycle, the speed of the pedal cannot be followed, and there is a danger of causing accidental injury, and the gear reducer used in the industry generally. Only the torque (torque) can be converted to a power of 6 Newtons per unit distance (meters). At this time, once the slope exceeds 15 degrees, the power output by the electric bicycle itself is not enough to climb. The person must exert a large amount of pedaling force to provide a large torque to climb the electric bicycle, which has its shortcomings in practical application. Therefore, the creator of this creation thinks about and designs a dual-harmonic power bicycle, in view of the above. The improvement of the existing technology is improved, thereby enhancing the implementation and utilization of the industry. [New Content] [0005] In view of the above-mentioned shortcomings of the prior art, the present invention designs a dual-harmonic power bicycle with patent elements such as novelty, advancement, and industrial utilization, in order to overcome the difficulties of the prior art. [0006] In order to achieve the above objectives, the technical means adopted by the present creation is to design a dual harmonic power bicycle, which includes the application of the following four innovative technologies; first, harmonic drive technology; second, synchronous high speed motor technology; Third, the position, speed, current double closed-loop control technology; Fourth, the power synthesis double beyond clutch technology. At the same time, the electric bicycle (or power-assisted bicycle) of the above four technical achievements is called: the dual-harmonic power bicycle, and the specific implementation status of the dual-harmonic power bicycle is as follows: [0007] - the body, the system For a bicycle, there is a five-way pipe fitting having a shaft space inside; a transmission mechanism correspondingly disposed on the body, having a chain and a flywheel driven by the chain; a crank axle form number A0101, page 4/19, correspondingly rotatably disposed in the shaft space of the five-way pipe member and penetrating through the core shaft space of the transmission mechanism, thereby being driven by a pedal of the body to rotate and reverse Driving the pedal, and the crankshaft and the transmission mechanism are connected to each other but independently rotate and do not interfere with each other, the transmission mechanism and the crankshaft can respectively drive the chain to drive the flywheel to rotate; a brushless Hallless motor and a harmonic reduction device, which is correspondingly disposed in the five-way pipe member, and correspondingly sleeved on the crankshaft to be a transmission mechanism; and a power component corresponding to The five-way tube at the outside. [0008] wherein the power assembly includes a power combining device disposed on one side of the harmonic speed reducing device and coupled to the chain, and driving the flywheel with the chain; wherein the power combining device has a ratchet ring, a first ratchet member, a ratchet member, a ratchet core and a second ratchet member, wherein the ratchet member is disposed in the ratchet ring, and the first ratchet member is located in the ratchet ring and Between the ratchet members, the ratchet core is disposed in the ratchet member, and the first ratchet member is correspondingly disposed between the ratchet ring and the ratchet member; wherein the first ratchet member and the second ratchet member The toothed part can be selectively upright or flat. [0009] The power assembly further includes a motor drive controller, a current generator rotor, and a power sensor; wherein the motor drive controller is electrically connected to the brushless Hallless motor; wherein the current occurs The rotor system is coupled to the harmonic reduction device; the force sensor power sensor outputs a sinusoidal waveform digital signal to the motor drive controller according to a change in the magnetic field of the current generator rotor rotation. [0010] wherein, the first power generated by the brushless Hallless motor operation is decelerated by the harmonic deceleration device and transmitted to the power synthesizing device, and then to the form number A0101, page 5 / 19 pages, M424298 transmission The mechanism drives the body to move, and the second power generated by the human pedaling force rotates the crankshaft, transmits the chain to the chain via the power synthesizing device, and then drives the body to move; wherein the harmonic deceleration device is harmonic The wave drive is moved by elastic deformation. [0011] wherein the harmonic reduction device comprises a machine member, a convex ring member, at least one bearing member, an inner wheel member and an outer wheel member, wherein the outer wheel member is provided with the inner wheel member, and the inner wheel member is disposed inside The bearing member is provided with the convex ring member, wherein the bearing member and the outer wall of the inner wheel member have elasticity and can perform deformation movement, and the convex ring member is disposed in the bearing member, Non-circular, as the cam member rotates, the outer wall of the bearing member and the inner wheel member will move with the deformation, and the outer wheel member is provided with a plurality of internal teeth, and the inner wheel member is provided with corresponding internal teeth The plurality of external teeth; wherein the bearing member is a ball bearing; wherein the convex ring member is elliptical; wherein the inner tooth is rigid and the outer tooth has elasticity; wherein the five-way pipe member is a frame connected to the faucet, the seat and the rear wheel frame of the body. [0012] The dual harmonic power bicycle of the present invention is designed to utilize the high reduction ratio of the harmonic reduction device, thereby outputting the most ergonomic output, and can cooperate with the user's pedaling speed to avoid the danger. And by the high transmission efficiency of the harmonic reduction device, the overall torque is increased, thereby increasing the slope of the slope of the double harmonic power bicycle climbing, and automatically adjusting the rotation speed of the motor according to the rotational speed of the user pedaling. This can solve the problem that the user automatically increases the power of the motor output when the user is tired, or automatically reduces the power of the motor output during the movement. [0013] At the same time, the harmonic transmission reduction mechanism can be used to realize the self-centered coaxiality of the electric vehicle.

Therefore, the center-mounted coaxial drive motor has the characteristics of small size, light weight, high efficiency, large output torque, simple structure, good structural rigidity and beautiful appearance. It will be the best driving method for electric bicycles in the future.
