摘要

本文主要對(duì)電動(dòng)牙刷主體進(jìn)行詳細(xì)的設(shè)計(jì)、計(jì)算、校核、分析、選型。在對(duì)電動(dòng)牙刷行業(yè)近年來(lái)國(guó)內(nèi)外發(fā)展情況調(diào)查的基礎(chǔ)上,對(duì)電動(dòng)牙刷的結(jié)構(gòu)進(jìn)行設(shè)計(jì)計(jì)算。分析了電動(dòng)牙刷要求實(shí)現(xiàn)的功能要求，了解了現(xiàn)有電動(dòng)牙刷機(jī)構(gòu)的工作原理，基本結(jié)構(gòu)，系統(tǒng)組成及功能；研究了電動(dòng)牙刷的系統(tǒng)構(gòu)成及功能，各部件的選型方法及材料選擇，特別是對(duì)其傳動(dòng)部分的研究是本文的重點(diǎn)。
電動(dòng)牙刷一個(gè)簡(jiǎn)單的機(jī)電一體化產(chǎn)品，融合了機(jī)械，材料，電機(jī)等相關(guān)技術(shù)。其主要技術(shù)路線是通過(guò)電池提供電力，使電機(jī)工作，通過(guò)傳動(dòng)部分結(jié)構(gòu)運(yùn)動(dòng)速度和軌跡來(lái)控制牙刷的振動(dòng)。
設(shè)計(jì)主要包括了電動(dòng)牙刷的外形結(jié)構(gòu)，傳動(dòng)部分的設(shè)計(jì)，裝配，選材，控制系統(tǒng)設(shè)計(jì)，電機(jī)選擇，以及運(yùn)動(dòng)模擬仿真。本文的設(shè)計(jì)中，電動(dòng)牙刷的結(jié)構(gòu)圖，裝配圖，零件圖，以及控制系統(tǒng)的電路圖都有詳細(xì)的介紹。
以本電動(dòng)牙刷設(shè)計(jì)作為畢業(yè)設(shè)計(jì)，其目的是通過(guò)切身實(shí)踐，對(duì)所學(xué)知識(shí)的一次全面、系統(tǒng)的復(fù)習(xí)，總結(jié)與完善，理論聯(lián)系實(shí)際，鍛煉自己在機(jī)械設(shè)計(jì)等方面實(shí)際的能力，并學(xué)會(huì)解決在實(shí)際設(shè)計(jì)過(guò)程中遇到的問(wèn)題的能力。

Abstract

 In this paper, I design, calculate, check, analyse, and select the main part of the electric toothbrush in detail. On the basis of the survey of the development of the electric toothbrush industry in recent years both at home and abroad, I analyse the demands of the functional requirements of the electric toothbrush, then I understand the working principle of the existing electric toothbrush, basic structure, composition and functions of the system. And I also study the structure and function of the electric toothbrush, the selection of the it`s components and material selection. Mainly the paper focus on the transmission of the toothbrush.
  Electric toothbrush is a simple mechanical-electrical integrated product. It is the integration of the utilization of the mechanical, microcontroller, materials, electrical and other related technologies. The battery provides the electricity by the battery so that the electrical body can work. And the vibration of the toothbrush is controlled by the velocity and the trajectory of the transmission structure .
 The paper includes the design of the shape and driving part of the electric toothbrush .And it used material selection, control system design, motor selection, and sports simulation. In this paper introduce the design of electric toothbrush, the structure of the electric toothbrush, assembling method , part drawings, as well as the circuit diagramsof the control system in detail. I choose the the design of the electric toothbrush as my graduation project to get and sum up comprehensive and systematic knowledge,to practice with theory ,to improve my mechanical design capabilitie through practice, to gain the abilities of solving the actual  problems .
Keywords：Electric toothbrush  confiqurable  motion simulation
