Description

自行車測力裝置bicycle dynamometer

本發明係提供一種自行車測力裝置，尤指一種可架設並偵測自行車於騎乘時對於前後移動方向之施力情形者。 The present invention provides a bicycle force measuring device, especially a device that can erect and detect the force applied to the direction of forward and backward movement of the bicycle when riding.

按，於空氣動力學中，其阻力主要可分為表面摩擦力與壓力阻力，其中依據表面摩擦力與壓力阻力所佔的比例可分為鈍形體(Bluff body or Blunt body)與流線體(Streamlined body)，而鈍形體主要之阻力來源為壓力阻力，壓力阻力主要係因物體前後壓力差所引起，而人體於流場中，亦被視為一種鈍型體，故當流體流經人體，亦將產生流動分離現象，而於後方產生相當大的尾流區，使壓差阻力遠大於摩擦阻力，其原理可適用於現今之競速比賽，由於選手所穿著之運動服裝，諸如：賽車服、運動衣、泳衣或潛水衣，其材質皆具有極大之差異性，而於相同之比賽下，若運動服裝之材質不同，於相異運動速度下之運動服裝之阻力亦不相同，尤以高速運動下之阻力差異性為更甚者，其將影響選手競速比賽時之運動速度，進而造就不同之比賽結果；因此各國團隊即另投入空氣動力之研究，如：空氣動力學握把、減阻服裝、空氣動力安全帽、板輪、護目鏡與襪子等相關產品，以達到減低阻力的效果，而其中，服裝仍為主要減阻之配件，故若無法對應競速比賽之通常運動速度予以選用或設計運動服裝之材質及表面粗糙度，則有影響比賽結果之虞。 Press, in aerodynamics, its resistance can be mainly divided into surface friction and pressure resistance, which can be divided into blunt body (Bluff body or Blunt body) and streamline body ( Streamlined body), and the main resistance source of blunt body is pressure resistance, which is mainly caused by the pressure difference between the front and back of the object, and the human body is also regarded as a blunt body in the flow field, so when the fluid flows through the human body, There will also be a flow separation phenomenon, and a considerable wake area will be generated in the rear, so that the pressure difference resistance is much greater than the friction resistance. , sportswear, swimsuits or diving suits, the materials are all very different, and in the same competition, if the materials of the sportswear are different, the resistance of the sportswear at different speeds is also different, especially at high speeds. The difference in resistance under sports is even worse, which will affect the speed of the players during the racing competition, and then lead to different results of the competition; therefore, the teams of various countries have invested in the research of aerodynamics, such as: aerodynamic grips, reducing weights, etc. Clothing, aerodynamic helmets, board wheels, goggles and socks and other related products to achieve the effect of reducing resistance, and among them, clothing It is still the main drag-reducing accessory, so if the material and surface roughness of the sportswear cannot be selected or designed to correspond to the normal speed of the racing competition, the result of the competition may be affected.

而於騎乘自行車之過程中之阻力除前述者外，亦包含使用者及自行車於行進方向上之投影面積所形成之空氣阻力、自行車行進時與地面之摩擦力，以及自行車於上坡行駛時重力於行駛方向反向之分量，現有之量測裝置雖可量測前述之阻力之量值，惟於自行車騎乘時，使用者施予自行車之力，亦將會使自由車產生前後移動之力量，若為能考量此力之產生，將使前述者所量測之阻力產生偏差，即使設計出具減阻功能之服裝配件，若檢測過程中具有偏差，將使無法精確得知服裝配件實質之減阻效果及精度，此將影響減阻服裝配件之設計，以及難以準確分析自行車騎乘時相關之力學問題。 In addition to the aforementioned, the resistance during riding a bicycle also includes the air resistance formed by the projected area of the user and the bicycle in the direction of travel, the friction force between the bicycle and the ground when the bicycle is traveling, and the friction when the bicycle is traveling uphill. The component of gravity in the opposite direction of travel. Although the existing measuring device can measure the magnitude of the aforementioned resistance, when riding a bicycle, the force exerted by the user on the bicycle will also cause the free bicycle to move forward and backward. Force, if the generation of this force can be considered, will cause deviations in the resistance measured by the aforementioned, even if the clothing accessories with drag reduction function are designed, if there is a deviation in the detection process, it will be impossible to accurately know the essence of the clothing accessories The drag reduction effect and accuracy will affect the design of drag reduction clothing accessories, and it is difficult to accurately analyze the mechanical problems related to bicycle riding.
