多功能健身车设计

摘    要

多功能式健身小车应用广泛。现有的健身器一般都采用，对人体单一部位进行锻炼，而对那些要求全身得到锻炼的适应能力比较差，直接影响了生产企业的经济效益。为此，该课题提出设计一种多功能式的健身小车，以适应市场需求。本文主要对多功能式健身小车从，针对现在产品中存在着规模大功能少等缺点，，多功能化，为本项目市场化、产业化运营奠定了基础。

鉴于本产品的定位，首先是为了健身的目的，再一个是一定要体现出小车的趣味性。所以在设计时，要充分的发挥多功能的目的。像一般的健身式的小车或者自行车，往往运动量较大，同时整个锻炼的过程枯燥乏味。这样就很难引起人们的兴趣，再一个在市场的定位上，主要是针对都市的白领。因为白领们的工作压力较大，并且他们一般没有大量的时间去参加一些锻炼性的活动。普通的健身方式也很难引起他们的兴趣，这样一种集多功能和锻炼于一体的双人健身小车肯定会在市场上有不错的反响的。

文章的开始总结归纳了现有的一些小车的特点，并且阐述了国内外的健身小车的发展状况，对国内这种健身小车的市场的前景进行了分析，得出了本小车在国内还是有非常广阔的市场；在文章的后面，根据机械原理上的已有的一些机构的运动的原理进行了分析，同时结合本健身小车的实现的功能，得出了小车的主要部分转向系统和前进系统采用的结构形式，转向是采用的齿轮的传动，前进是齿轮齿条的传动，这样同时可以锻炼身体的三个主要部位；对小车的整体进行了受力的分析，并且对小车的关键部件进行了强度和寿命的校核。

A bike of entertainment fitness

Abstract

The bike of entertainment fitness is widely used. Fitness existing devices are generally single function，a single site on the human body to exercise，and for those who require full-body exercise has been relatively poor ability to adapt to a direct impact on the economic benefits of the production enterprises。To this end, the design of the subject of a multi-purpose family fitness, and to adapt to market demand。This paper focuses on the entertainment training equipment from the actual work needs to proceed, for now there is less large-scale features, aimed at the family-oriented, multi-functional, our project market-oriented, industrial operations laid the foundation,

In view of the positioning of this product, the first is for the purpose of fitness, then one must reflect the car's interesting. At design time, to fully play entertainment purposes. Car or bicycle-like general fitness, often large amount of movement, while the entire exercise boring. This makes it difficult to attract interest, and then a positioning in the market, mainly for urban white-collar. Because of the white-collar work pressure, and they generally do not have a lot of time to participate in some exercise activities. The ordinary fitness is difficult to arouse their interest, such a set of fun and exercise in one of the fitness equipment will have a good response in the market.

The beginning of the article summarizes some of the existing features of the car, and describes the development of the car at home and abroad fitness, this fitness car market outlook, come to the car at home or have a very broad market; later in the article, according to the principles of the movement of the mechanical principle on some bodies of the analysis, combined to achieve the function of the fitness car come to a main part of a car steering system and forward system using structure, steering gear drive, forward is the rack and pinion drive, can exercise the three main parts of the body; analysis of the force of the car as a whole, and the key components of the car checking of strength and life.
