内容简介：

内容摘要：本设计拟设计一种老年人阅读时使用的放大镜搁置的摆放支架，它不仅可以按照老人阅读的速度调整纵向（y）/横向（x）的位置，实现类似我们利用电脑阅读时的自动滚屏操作。该阅读书架是利用直线电机设计的一种新颖的机械结构，可以实现利用手动遥控控制放大镜能在x和y方向自如的移动，以实现阅读不同的区域。本设计基于机械设计及其自动化、力学、材料学、工业设计等相关专业学科的知识体系的前提下完成设备的发明和制做。应用机械专业的相关知识完成产品的总体设计，应用力学，材料学的相关知识完成对产品的受力、寿命，成本等方面的检测，在工业设计的知识体系下应用美学与外观设计等知识对产品的外观进行美化，使产品更人性化，更安全。应用各种传动机构实现产品的预期设计功能，主要运用步进电机带动丝杠，同步齿形带，等简单的机械结构实现对放大镜移动的控制。关键词： 力学 机械设计 自动化 步进电机 机电一体化Abstract: This design is proposed to design a place bracket for magnifying glass used in the reading of the old people. It can not only adjust the vertical (y) / horizontal (x) position according to the speed of the old people reading, to achieve the automatic roll screen operation similar to the use of computer reading. The reading shelf is a novel mechanical structure designed by using linear motor, and it can be implemented using the manual remote control a magnifying glass moving freely in the x and y directions, in order to realize the reading different area. This design based on mechanical design and automation, mechanics, materials science, industrial design or related professional discipline knowledge system to complete the invention of the equipment and manufacturing. Application of mechanical professional knowledge to complete the overall design of the product, Applied mechanics, materials science related knowledge to complete the products force, life, cost and other aspects of the detection, Under the knowledge system of industrial design, the application of aesthetics and design knowledge to beautify the appearance of the product, to make it more humanity, more secure. Application of various transmission mechanism to achieve the expected design product function, mainly using the stepper motor drive screw, simple mechanical structure such as synchronous cog belt to achieve control of the movement of th
