摘要

随着当下中国的科学技术得到了不断发展和竞争的越来越激烈，城市中的小型商店正在逐步减少，劳动力工资不断提高，促进了自动售货机的迅速发展，尤其是在一些公共场所中，对于自动售货机的需求程度在不断提高，各种各样的自动售货机出现在了人类社会生活当中。而在医院儿童住院区域，许多家长因为孩子需要带在身边而不方便出去买东西，因此需要自动售货机来使购买商品变得更加方便。

本次自动售货机的结构设计主要围绕的自动售货机的箱体设计，自动售货机的出货机构设计，自动售货机的基本工作方式。根据常见自动售货机的外观以及内在构造，分析它的功能以及所要实现的功能所对应的结构设计，最终整理出一套方案，相应的设计出一款适合放置在医院儿童主院区的自动售货机的结构。

Abstract

Along with the current Chinese science and technology has developed and increasingly fierce competition, small shops in the city are gradually reduced, labor wages continue to improve, promote the rapid development of the vending machine, especially in some public places, for the vending machine demand continues to increase, a variety of automatic vending machine in human social life. In the hospital children's ward, many parents need to take their children around because they need to be around, so vending machines are needed to make it easier to buy goods.

The vending machine structure design mainly revolves around the vending machine box design, the vending machine shipment organization design, the vending machine basic work way. According to the common vending machine appearance and internal structure, the structure design of the corresponding functional analysis of it and to achieve the function, finally sort out a scheme to design a suitable vending machine is placed in the children's Hospital, the main hospital area of the corresponding structure.
