Description
本創作係有關一種健身車之制動裝置，尤指一種透過驅動器帶動永久磁鐵產生不同磁場大小，以調整健身車制動效果的健身車飛輪結構之內制動裝置。The present invention relates to a brake device for an exercise bike, and more particularly to a brake device for an exercise bike flywheel structure that uses a drive to drive a permanent magnet to generate different magnetic fields to adjust the braking effect of the exercise bike.
健身車不但可以提升心肺功能，而且對於背部肌肉、臀部及下肢的鍛鍊也有很好的效果，再加上健身車不但可以做出爬坡及衝刺等動作，而且透過立式或斜躺式的騎乘方式，亦可達到不同的運動效果，因此相當受到喜歡運動者的喜好與歡迎。The exercise bike can not only improve the heart and lung function, but also have a good effect on the back muscles, buttocks and lower limbs. In addition, the exercise bike can not only perform climbing and sprinting, but also through vertical or reclining riding. The riding method can also achieve different sports effects, so it is quite popular and popular with the likes of sports people.
而一般健身車上的制動裝置，多數是採用摩擦式或是油壓式為主，其中摩擦式的制動器缺點在於長期摩擦下會造成磨損，以及不穩定之問題，而油壓式則會有漏油、噪音與高溫的問題，因此近年來出現了以磁場之渦電流為阻力，作為健身車的制動裝置。Most of the brake devices on the exercise bike are mainly friction type or hydraulic type. The friction type brake has the disadvantages of causing wear and instability under long-term friction, and the oil pressure type will leak. Oil, noise and high temperature problems have occurred in recent years as the resistance of the magnetic field eddy current as a brake device for exercise bikes.
例如：中華民國新型第M472133號「健身車剎車磁控及調整裝置改良」，其係透過一導磁件由飛輪之外緣兩側產生磁阻力，以干涉飛輪轉動，進而達到剎車或調整飛輪阻力之目的，以及中華明國發明專利第I349077號「制動磁控組結構」，係透過動力裝置帶動轉盤旋轉，並在轉盤旋轉的同時以拉桿帶動定子彎折，而以各定子彎折不同之角度，使定子外緣 所設之磁體與飛輪內緣之金屬環體間之間隙改變進而改變磁通密度，藉此以控制阻力之大小，以及美國專利第US6360855、US5711404、US6345703、US6273845及US5851165號專利案，惟，上述專利案，為了達到利用磁場渦流電調整飛輪阻力，所採用之結構均同樣都具有結構複雜的問題，除了容易導致騎乘健身車之使用者不易操控外，過於複雜的結構亦容易導致故障機率的增加，因而有改良之必要。For example: the new Republic of China No. M472133 "Improvement of brake magnet control and adjustment device for exercise bikes", which generates magnetic resistance from both sides of the outer edge of the flywheel through a magnetic guide to interfere with the rotation of the flywheel, thereby reaching the brake or adjusting the flywheel. The purpose of the resistance, as well as the Chinese Mingguo invention patent No. I349077 "Brake magnetron group structure", is to drive the turntable to rotate through the power unit, and to drive the stator to bend while the turntable rotates, and the stator bends differently. Angle, making the outer edge of the stator The gap between the magnet and the metal ring of the inner edge of the flywheel is changed to change the magnetic flux density, thereby controlling the magnitude of the resistance, as well as the patents of US Pat. No. 6,360,855, US Pat. No. 5,571,404, US Pat. In the patent case, in order to achieve the adjustment of the flywheel resistance by using the magnetic field eddy current, the structures used are also complicated in structure. In addition to being easy to cause the user of the riding exercise bike to be difficult to control, an overly complicated structure is also likely to cause a failure probability. Increased, so there is a need for improvement.
由此可見，上述習用健身車的制動裝置仍有諸多不足，實非一良善之設計，而亟待加以改良。It can be seen that there are still many shortcomings in the brake device of the above-mentioned exercise bicycle, which is not a good design and needs to be improved.

The shaft 331 is pivotally connected to the linkage unit 354, and the motor is coupled to the cord reel 351 by a pull cord (not shown).
本創作健身車飛輪1結構之內制動裝置3作動時，係透過飛輪 1轉動帶動繞設於同心圓金屬圈13內環面之轉子22於定子21外緣轉動，而令該定子21與該等轉子22產生交流電流，並透過交流電流驅使馬達啟動並拉動拉繩帶動捲線器351轉動，同時藉由捲線器351之轉動帶動連動單元354旋轉，而由於該第一連動桿352及該第二連動桿353之一端係分別以一卡銷355 與該連動單元354相對兩側所設之卡孔3541固定，因此當連動單元354旋轉時，該第一連動桿352及第二連桿與連動單元354固定之一端會受連動單元354之帶動而隨之位移，並使第一連桿及第二連桿帶動第一簧片32及第二簧片33進行互相對稱之位移，以調整永久磁鐵36與阻力環11產生之磁場強度，進而調整飛輪1轉動割磁場產生渦流阻尼效果。When the brake device 3 in the structure of the flywheel 1 of the present exercise bicycle is actuated, the flywheel is transmitted through the flywheel 1 Rotating the rotor 22 wound around the inner ring surface of the concentric circle 13 to rotate on the outer edge of the stator 21, so that the stator 21 and the rotor 22 generate an alternating current, and the alternating current drives the motor to start and pull the rope to drive The reel 351 is rotated, and the linkage unit 354 is rotated by the rotation of the reel 351, and one end of the first linkage rod 352 and the second linkage rod 353 is respectively a bayonet 355. The card hole 3541 provided on the opposite sides of the interlocking unit 354 is fixed. Therefore, when the linking unit 354 rotates, one end of the first linking rod 352 and the second connecting rod and the linking unit 354 are driven by the linking unit 354. With the displacement, the first link and the second link drive the first reed 32 and the second reed 33 to be symmetrically displaced to adjust the magnetic field strength generated by the permanent magnet 36 and the resistance ring 11, thereby adjusting the flywheel. 1 Rotating the cutting magnetic field produces an eddy current damping effect.
例如，當連動單元354轉動而帶動第一連動桿352及第二連動 桿353與連動單元354固定之一端，向遠離第一簧片32及第二簧片33之方向移動，此時，第一連桿及第二連桿則以與第一樞接端及第二樞接端樞接之一端，帶動第一簧片32及第二簧片33像遠離飛輪1之阻力環11方向位移，使第一簧片32及第二簧片33外緣佈設之永久磁鐵36與阻力環11產生之渦流阻尼效果減少，降低飛輪1轉動之阻力，而當連動單元354轉動而帶動第一連動桿352及第二連動桿353與連動單元354固定之一端，向接近第一簧片32及第二簧片33之方向移動時，則第一連桿及第二連桿則以與第一樞接端及第二樞接端樞接之一端，即會帶動第一簧片32及第二簧片33像接近飛輪1之阻力環11方向位移，同時藉由彈簧34之彈性將第一簧片32之第一樞接端及第二簧片33之第二樞接端向阻力環11方向撐開，而使第一簧片32及第二簧片33外緣佈設之永久磁鐵36接近阻力環11，以增加永久磁鐵36與阻力環11產生之渦流阻尼效果，進而導致飛輪1轉動之阻力增加，另外，本創作健身車飛輪1結構之內制動裝置3亦可透過設定馬達轉動時拉動拉繩之段數，用以微調飛輪1轉動割磁場產生渦流阻尼效果。For example, when the linkage unit 354 rotates to drive the first linkage rod 352 and the second linkage The rod 353 and one of the interlocking units 354 are fixed to move away from the first reed 32 and the second reed 33. At this time, the first link and the second link are connected to the first pivoting end and the second One end of the pivoting end pivotally drives the first reed 32 and the second reed 33 to be displaced away from the resistance ring 11 of the flywheel 1 to make the permanent magnet 36 disposed on the outer edge of the first reed 32 and the second reed 33. The eddy current damping effect generated by the resistance ring 11 is reduced, and the resistance of the flywheel 1 is reduced. When the interlocking unit 354 is rotated to drive the first linkage rod 352 and the second linkage rod 353 and the linkage unit 354 to fix one end, the first spring is approached. When the direction of the piece 32 and the second reed 33 is moved, the first link and the second link are pivotally connected to one end of the first pivotal end and the second pivotal end, that is, the first reed 32 is driven. And the second reed 33 is displaced in the direction of the resistance ring 11 of the flywheel 1, and the first pivotal end of the first reed 32 and the second pivotal end of the second reed 33 are resisted by the elasticity of the spring 34. The ring 11 is extended, and the permanent magnets 36 disposed on the outer edges of the first reed 32 and the second reed 33 are brought close to the resistance ring 11 to increase the permanent The eddy current damping effect generated by the magnet 36 and the resistance ring 11 further increases the resistance of the flywheel 1 to rotate. In addition, the braking device 3 in the structure of the flywheel 1 of the present exercise bicycle can also pull the number of the pulling rope when the motor is rotated. The eddy current damping effect is generated by fine-tuning the rotating magnetic field of the flywheel 1.
由上所述，本創作健身車飛輪結構之內制動裝置相較習知之結構與技術，更具有以下之特點及功效：As described above, the brake device within the flywheel structure of the creation exercise bicycle has the following features and functions compared with the conventional structure and technology:
1.本創作透過馬達拉動拉繩而帶動捲線器轉動，並透過捲線器之轉動而使第一連桿及第二連桿拉動第一簧片及第二簧片位移，而使第一簧片及第二簧片上之永久磁鐵與阻力環產生不同的渦流效率，而達到調整阻力之目的，較之習知結構，其結構更為簡單且易於操作。1. The present invention drives the cord to drive the cord to rotate, and the first link and the second link pull the first reed and the second reed by the rotation of the reel, so that the first reed The permanent magnet on the second reed and the resistance ring produce different eddy current efficiencies, and the purpose of adjusting the resistance is simpler and easier to operate than the conventional structure.
2.本創作透過飛輪轉動時，由發電線圈之轉子與定子產生之交流電流供馬達使用，因此無須再外接電源供馬達帶動第一簧片及第二簧片產生位移。2. When the creation is rotated by the flywheel, the alternating current generated by the rotor and the stator of the power generating coil is used by the motor, so that no external power supply is required for the motor to drive the displacement of the first reed and the second reed.
