碩士 === 南台科技大學 === 機械工程系 === 99 === The sensing system of the power-assisted wheelchair is a wheelchair through the user operation of the movement, sensing the strength and the direction, will be transformed into direct power source signal and provide power to wheelchairs to help drive the device. After analysis of existing patents related to power-assisted wheelchair, we can find the main research of the power-assisted wheelchair that needs to solve the problem of the wire around, and almost of the design of the case showing a lack of reliability. This results from the sensing mechanism design for a set of institutions with reliability, and to assess the design of the selection design of the sensing element. The design of a new body may be formed by the analysis of the characteristics of a wheelchair, were hand-wheel, big wheel and the sensor output, then refer to two degrees of freedom of the body, and then through the motion design, got the input angle and then get the output position, Finally, the detailed design for the needs of each link, and the members of the dimensions and parameters of the parts designed, so that can produce the normal operation of the prototype machine. Therefore, this thesis is the design of sensing system of the power-assisted wheelchair, the use of the patent search, analysis of 10 U.S. patents and 4 patents Republic of China, after the results of patent analysis, define the problem of the sensing system with the sensing body and sensing components. Production prototype machine by conceptual design, detailed calculation of the required size of detail design by the basic formula for gear, and draw results graphics done by a computer model , output a concept design and computer models to help move the same time and make sense wheelchair system prototype machine, finally, the prototype machine will complete, then test of progress and record the results, the design of future follow-up to power-assisted wheelchair can be used as reference.
