Academic Forum Technology entrepreneur bookmark 0 Multi-function home fitness equipment design Li Minglin Zeng Fanli Liang Zhan Chen Jingwen Wang Suran (Harbin University of Commerce, Harbin Institute of Light Industry This Harbin Institute of Technology fitness equipment can be converted in chairs and fitness equipment. This section of fitness equipment also Easy to use, small footprint, low cost, strong applicability 1 Introduction 1.1 The status of home fitness equipment from the collected data shows that fitness equipment is divided into three major categories. Skipping rope, dumbbells, etc. is relatively simple and simple Fitness equipment, such low-end fitness equipment, a single performance, simple structure, but easy to use, but also the essential fitness equipment for most consumers at home.Secondarily, mid-range fitness equipment, such as treadmills, exercise bikes, etc. The structure of the device is relatively complex, some of the performance has also reached a higher level, and the floor space is smaller.The third is high-end fitness equipment, such as multi-functional treadmills, etc. This type of fitness equipment has running, rowing, riding, Rotary waist, push-ups and other features, the price is relatively expensive, mostly in thousands or even more than 10,000 yuan, and covers an area larger 1.2 The meaning and purpose of the design According to what we know about the present fitness equipment, the significance of our design is to promote the development and improvement of the fitness equipment industry in China. The novel is for the sake of our own health. After all, the current social causes Modern people do not have much spare time to add vitality to their own health.1.3 Design Requirements Design works should meet the following requirements: can be converted in the seat and exerciser; suitable for users weighing less than 100Kg; It is reasonable, simple in structure, easy to produce, adopts assembly structure, easy for packaging and transportation, reasonable in material selection, and economical in performance.2 Overall Design 2.1 Function Definition This type of fitness equipment belongs to multi-functional fitness equipment, which can be used in fitness equipment and seats. In order to meet the needs of the user, three fitness items can be performed when they are converted into a fitness state: 1. Lying on a fitness equipment for sit-ups; 2. Adjusting the fitness equipment according to the needs of the user To a certain point of view by stretching the spring can exercise the muscles of the arm; 3, with the foot on the ankle mechanism can live Knee joint and leg muscles can be exercised at the same time.The angle between the chair and the exerciser can be up to 40 degrees. When the mechanism is at 120 degrees, the mechanism is the seat, within the adjustable range of 40 degrees. According to the needs of the user, when adjusting to the limit angle of this angle, this mechanism is an exercise machine 2.2 Working principle The device is mainly composed of a detachable linkage mechanism, and its adjustment and positioning mainly come from positioning pins. The positioning pin cooperates with the support keg and the support vat, according to different positioning holes, changing the angle between the small pad and the large pad to meet the different needs of users, and on this basis, adjust the accessories and The position between the feet to achieve more work position, the above is the conversion of the multifunctional fitness device between the seat and the exercise device; the pedal mechanism mainly utilizes the power principle of the bicycle, and the leg of the person is wound through the ankle. The rotation of the base point to do the rotation movement, in the process of active knee joints, ankle joints, at the same time in the process of exercise so that the leg muscles have been more comprehensive exercise; When the user pulls the spring by force, the spring's reaction force causes the user to receive a certain force in the opposite direction. This is to use the nature of the spring to achieve the exercise. Arm muscles. 2.3 Overall structure 2.3.1 Tension mechanism The tension mechanism consists of a spring, a spring handle, and a handle. The arm's stretching movement causes the spring to deform to cause a reaction force, and the reaction force and the arm's tension are relative to each other, so that the arm is subjected to a certain resistance. In order to achieve the effect of exercising arm muscles. 2.3.2 The ankle mechanism The ankle mechanism consists of a foot plate, a connecting rod, a shaft, a bearing and a base rod. The ankle mechanism and the handle are detachable. Both are detachable from the frame when they are turned into seats. When the pedal mechanism and its parts are disassembled, the pedal mechanism mainly utilizes the dynamic principle of the bicycle, and the leg is rotated around the rotation base point through the ankle. In this process, the knee joint and the ankle joint are activated. At the same time, during exercise, the muscles of the legs have been fully exercised. 2.3.3 Abdominal Exercise Mechanisms and Racks Abdominal exercise mechanisms and stands are mainly supported by front legs, support panels, support panels, hook brackets, support kegs, and support vats. The front leg and the supporting plate are matched by bolts. The bolts mainly play the role of connection, and the force mainly depends on the support of the front leg to the supporting plate to achieve the force. The abdomen exercise mechanism is inseparable from the frame, while the frame provides an effective platform for the entire organization and parts. 3 Summary The Innovation and Entrepreneurship Competition provided us with an opportunity to exercise our own design and computational capabilities, but also improved our logical imagination ability. Although we encountered various difficulties in the process, these difficulties can only make us The teamwork ability has been further enhanced. This design has made us learn what we have learned for the past four years. We are very happy with this, and this design allows us to better integrate theory with practice. It allows us to better understand the market, function and insufficiency of multifunctional home fitness machines. Although this process is very hard, it gives us more opportunities to learn. We believe that this design will allow us to It will help in future work.
