They are energy-saving and carbon-reducing, and also have the effect of leisure and relaxation, and are an economical and practical transportation and leisure tool.
在骑乘脚踏车时，为了因应不同的环境、路况与车速的变化，骑乘者必须依据骑乘当时的环境及路况来改变骑乘时的踩踏力及转速。而脚踏车组件中其中的变速器，即是提供脚踏车不同的转速比，让骑乘者依据环境及路况来调整脚踏车不同的转速比，而获得较佳的骑乘状况。简单而言，变速器的重要性是在「上坡省力，下坡加速省时」，所以对于脚踏车而言，变速器是提供一种省时省力的器具。When riding a bicycle, in order to adapt to different environments, road conditions and changes in speed, the rider must change the pedaling force and speed when riding according to the environment and road conditions at the time of riding. The transmission in the bicycle assembly provides a different speed ratio of the bicycle, so that the rider can adjust the different speed ratios of the bicycle according to the environment and the road condition, thereby obtaining a better riding condition. In short, the importance of the transmission is to "uphill and labor-saving, downhill acceleration and time saving", so for the bicycle, the transmission provides a time-saving and labor-saving device.
现有技术的脚踏车变速器，通常是借由导链器来改变链条连结齿轮盘组的位置，用以改便前后齿轮盘组的齿轮比，以达到变速的效果。其操作上，是借由操作变速把手上所设的变速调整钮，透过钢索拉动变速器定位，导引链条在齿轮盘组上的位置，而达到变速的目的。In the prior art bicycle transmission, the position of the chain connecting the gear set is usually changed by the chain guide to change the gear ratio of the front and rear gear sets to achieve the shifting effect.

The port 311 and the guide port 314 protrude from the stopper hole 142 of the shaft 140, and the stopper needle 343 retractably protrudes from the stopper hole 142. That is, when the bicycle is stepped on, the fourth guide sprocket 224 is rotated along with the chain 420, and then the stop control panel 320 is rotated, and the centrifugal force of the rotation causes the bead 330 to shift outward, and The stop coil 340 expands outwardly, so that the stop needle 343 as the movable end 342 of the stop coil 340 is retracted from the stop hole 142 of the guide shaft 140, and the stop needle 343 is not blocked by the guide shaft 140. The control hole of the control unit 200 can be changed by sliding on the guide shaft 140 according to the rotational speed of the pedaling at the time; when the bicycle is not stepped on during traveling (for example, when going downhill), the fourth guide The sprocket 224 and the stop control disc 320 are not rotated, so that the stop coil 340 is elastically restored, so that the stop pin 343 of the movable end 342 protrudes outwardly and protrudes from one of the stop holes 142 of the guide shaft 140. Therefore, the control rod 210 of the control unit 200 is maintained at the current gear position, and is prevented from being automatically adjusted to the low gear position due to the temporary unstepped.
止档单元300的盖体350则盖合于止档盒体310，使其外观保持完整。The cover 350 of the stop unit 300 is then closed to the stop case 310 to keep its appearance intact.
依据本实施方式的加挂式可调整脚踏车全自动变速器，于装设时，系以加挂方式设于脚踏车400齿轮盘组410之链条420行经的路径上即可，其无需将脚踏车车体作任何的变动。其亦可将脚踏车400的齿轮盘组410容置于本实用新型变速器其中的箱体110，再将箱体110连同齿轮盘组410设于脚踏车400车架的后轴430上，其在装设上及对位上更为简易。According to the embodiment of the present invention, the automatic adjustable transmission of the adjustable bicycle can be installed on the path of the chain 420 of the bicycle gear set 410 of the bicycle 400 in a hanging manner, which does not require the bicycle body to be used. Any changes. It can also accommodate the gear set 410 of the bicycle 400 in the box 110 of the transmission of the present invention, and then set the box 110 together with the gear set 410 on the rear axle 430 of the bicycle 400 frame. It is easier to go up and match.
在踩踏使用时，于脚踏车行进当中，必然会随着速度及档位产生不同的扭力。依据本发明一实施方式之加挂式可调整脚踏车全自动变速器，当使用者踩踏的扭力逐渐增大时，其扭力将会克服扭力控制簧230所预设的扭力，使得控制单元200的控制棒210及其作动杆217被迫以导轴140为轴而前倾，终至触及下档导板130的斜边后端部132。下档导板130之斜边后端部132的斜边迫使控制棒210往低档方向(即内侧板112方向)移动，而落入于新的低档位的档位阻片120中，同时引导链条420往内链合于齿轮盘组410其中低档位的齿盘(即较大外径的齿盘)。在此新的低档位之阻片中，控制棒210重新依变化后的扭力再次运作，而落入再次新的档位。周而复始。如此，即可依逐渐增大的踩踏扭力，使得控制棒210逐步落入于低档位的阻片120并带动链条420逐步落入于低档位的齿轮盘组410，达到自动变速之目的及作用。When pedaling, when the bicycle is traveling, it will inevitably produce different torque with speed and gear position. According to an embodiment of the present invention, the adjustable adjustable bicycle automatic transmission, when the user's pedaling torque is gradually increased, the torque will overcome the torque of the torque control spring 230, so that the control rod of the control unit 200 The 210 and its actuating lever 217 are forced to lean forward with the guide shaft 140 as an axis, and finally reach the oblique rear end portion 132 of the lower guide 130. The oblique side of the beveled rear end portion 132 of the lower guide 130 urges the control rod 210 to move in the lower direction (i.e., the inner side plate 112) and falls into the new lower gear position stop 120 while guiding the chain 420. Inwardly coupled to the gear plate 410 of the gear set 410 (ie, the larger outer diameter of the spur). In this new low gear block, the control rod 210 again operates again according to the changed torque and falls into a new gear position. Repeatedly. In this way, according to the gradually increasing pedaling torque, the control rod 210 gradually falls into the low-position resistance piece 120 and drives the chain 420 to gradually fall into the low-range gear disk group 410, thereby achieving the purpose and function of the automatic shifting.
当使用者踩踏的扭力小于扭力控制簧230的扭力时，控制单元200的控制棒210及其作动杆217乃以导轴140为轴而后仰，于作动杆217后仰至档位阻片120之后端部123的圆弧角端126时，因拉索242的拉力，使得控制棒210及其作动杆217往高档方向(即外侧板113方向)跳动，而落入于新的高档位之阻片中，同时引导链条420往外链合于齿轮盘组410其中高档位的齿盘(即较小外径的齿盘)。在此新的高档位之阻片中，控制棒210重新依变化后的扭力再次运作，而落入再次新的档位。周而复始。如此，即可依逐渐减小的踩踏扭力，使得控制棒210逐步落入于高档位的阻片120并带动链条420逐步落入于高档位的齿轮盘组410，达到自动变速之目的及作用。在最高档位时，限位内突杆151可限制控制棒210过度后仰，以避免其碰触到齿轮盘组410。When the torque of the user is less than the torque of the torsion control spring 230, the control rod 210 of the control unit 200 and the actuating lever 217 thereof are tilted with the guide shaft 140 as an axis, and the operating rod 217 is tilted back to the position block. When the arcuate end 126 of the end portion 123 is 120, the tension of the cable 242 causes the control rod 210 and its actuating rod 217 to jump in the high-grade direction (ie, the outer plate 113 direction), and falls into the new high-grade position. In the block, the guiding chain 420 is simultaneously coupled to the gear plate of the gear plate set 410 (ie, the toothed disk of the smaller outer diameter). In this new high-end block, the control rod 210 is again operated again according to the changed torque, and falls into a new gear position again. Repeatedly. In this way, the stepping torque can be gradually reduced, so that the control rod 210 gradually falls into the high-end resistance piece 120 and drives the chain 420 to gradually fall into the high-end gear plate group 410, thereby achieving the purpose and function of the automatic shifting. In the highest gear position, the limit inner protrusion 151 can limit the control rod 210 from over-tilting to avoid it touching the gear set 410.
于上述自动变档的过程当中，链条420依长度调节机构250的作用，而相对地调节链条420实质作用于齿轮盘组410的长度，亦即，依长度调节机构250而随时调节链条420链合于齿轮盘组410的适当紧度。During the above automatic shifting process, the chain 420 adjusts the length of the chain 420 substantially acting on the length of the gear set 410 according to the action of the length adjusting mechanism 250, that is, the chain 420 is adjusted at any time according to the length adjusting mechanism 250. Appropriate tightness to the gear set 410.
如上述，当脚踏车于行进当中未被踩踏时(例如下坡时)，第四导链轮224及与该第四导链轮连动的止档控制盘320系未转动，使得原来由于转动之离心力而往外圈扩大的止档簧圈340弹性复原而往内圈缩小，相对地使得止档簧圈340之活动端342的止档针343外突，而突伸于导轴140的其中一止档孔142，使得控制单元200之控制棒210保持于当时的档位，避免因一时的未踩踏而被自动调节至高档位。待链条420重新转动时，因离心力的作用，使得止档针343自止档孔142拉起，而回复原有的运作程序。As described above, when the bicycle is not stepped on during traveling (for example, when going downhill), the fourth guide sprocket 224 and the stop control panel 320 that is interlocked with the fourth guide sprocket are not rotated, so that the original rotation The retaining ring coil 340, which is expanded by the centrifugal force and expanded toward the outer ring, is elastically restored to be reduced toward the inner ring, so that the stopper pin 343 of the movable end 342 of the stop coil 340 protrudes outwardly and protrudes from one of the guide shafts 140. The gear hole 142 allows the control rod 210 of the control unit 200 to remain in the current gear position, so as to be automatically adjusted to the high position due to the temporary unstepped. When the chain 420 is rotated again, the stopper needle 343 is pulled up from the stopper hole 142 due to the centrifugal force, and the original operation procedure is restored.
使用者可依个人的体力、骑乘习惯、以及各地不同的路况，微微调整档位阻片120前后的位置，甚至取消某些阻片；亦可依体能状况，更换不同扭力的扭力控制簧230，或***于不同孔位的插孔216而设定不同的扭力，以提前或延后换入较高档位的时机，致达随心所欲地可调整自动变速的作用。The user can slightly adjust the position of the front and rear of the gear block 120 according to the individual's physical strength, riding habits, and different road conditions, and even cancel some of the resistance pieces; or replace the torque control spring 230 with different torque according to the physical condition. , or insert the jacks 216 in different hole positions and set different torques to advance or delay the timing of shifting into the higher gears, so that the automatic shifting effect can be adjusted as desired.
采用本实用新型技术方案，在使用过程中还兼具有节能减碳之效果，例如：以15km/hr骑乘，每小时消耗能210kcal。即 14kcal/km每kcal 呼出175ml 之CO2 (采用平均值)每骑乘1km 呼出14*175=2450ml =2.45L之CO2。即1/10 mole ,重量4.4g之CO2。全球自行车量十亿辆。每日假设平均骑乘5km, ,14*175=2455*10^9*3.6*10^2*4.4=7.9*10^12g=7.9*10^6T年全球其总排放量为7.9*10^6T。By adopting the technical scheme of the utility model, the utility model also has the effects of energy saving and carbon reduction during use, for example, riding at 15 km/hr, and consuming 210 kcal per hour. which is 14kcal/km exhaled 175ml of CO2 per kcal (using the average) 1km per ride Exhaled 14*175=2450ml = 2.45L of CO2. 1/10 mole , weight 4.4g of CO2. There are billions of bicycles in the world. Assuming an average ride of 5km per day, , 14*175=2455*10^9*3.6*10^2*4.4=7.9*10^12g=7.9*10^6T The global total emissions are 7.9*10^6T.
本装置造价低廉维修简单，假设能节约1/10之体能，减碳7.9*10^5T。此数值相当于34*10^7L汽油燃放量。若以现况，即变速车3*10^8计，更少于而减排24*10^5T之Oo2，相当于11*10^7L汽油燃放量。The device is low in cost and easy to maintain. It is assumed that it can save 1/10 of the physical energy and reduce carbon by 7.9*10^5T. This value is equivalent to 34*10^7L gasoline discharge. If the current situation, that is, the transmission car 3*10^8, is less than the emission of 24*10^5T Oo2, which is equivalent to 11*10^7L gasoline discharge.
