本研究是針對現今螢幕支架及各類型轉軸的專利公報加以收集整理,依據轉軸阻力產生的方式及作動連續性進行分類與分析,並探討不同的設計所造成的優缺點有那些,再依據分析結果來探討高阻力轉軸裝置的發展趨勢,作為新設計高阻力轉軸裝置設計時的參考方向。 本研究依據創新機構設計流程,輔以力學及機構學的觀念來對高阻力轉軸裝置進行設計,使其具有使用、操作及收折都方便的功能;本研究所設計的軸心螺絲在相同的摩擦面積及正向力的條件下,其扭力產出效能可提升40%,而在相同的摩擦面積及扭力的條件下,其所需之正向力可降低30%,因此可有效的降低高阻力轉軸部份摩耗的發生;此外本研究利用3D繪圖軟體Solid Works來建立3D Model。 本研究以Solid Works建立3D Model後,運用Pro/Engineer Wildfire內含之Pro/Mechanism模組進行動態模擬,接著利用COSMOS之電腦輔助分析軟體進行高阻力轉軸裝置的應力分析,藉此確定其應力負荷狀況,並將分析之結果提供為後續設計修改及生產實體的參考。
This research collected and classified the patent communiqués of the screen holders and all kinds of hinges which classified and analyzed these communiqués according to the methods of producing friction and the continuity of motion. This research discusses the advantages and the drawbacks of the different designs of these communiqués. Then to bring out the theme of development for high friction hinges as a reference for the new designs of high friction hinges according to the result of analysis. This research attempted to design a high friction hinge, which provides user-friendly and easy folding functions with creative design flow and the concept of mechanics. This research designed an axle screw which can reduce the loss of friction for the high friction hinge. First, when the friction area and the normal force are equal, the axle screw can increase the efficiency of produce the torque, 40%. Second, when the friction area and the torque are equal, the axle screw can reduce the requirement of the normal force, 30%. Furthermore, it builds a 3D model with the 3D drawing software, Solid Works. After the 3D model had been built, this research processed motion simulations via the module of Pro/Mechanism within Pro/Engineer Wildfire and then made use of the Cosmos, an auxiliary software, making stress analysis of this high friction hinge for verifying the status of stress loading. The conclusion of this research may benefit further researches, designs or production.
