Description

All-in-one comprehensive fitness equipment with one arm using electro-hydraulic {all in one comprehensive fitness equipment with one arm using electro-hydraulic}

The present invention relates to exercise equipment, and more specifically, the exercise load is controlled by an electrohydraulic actuator, which not only reduces the inconvenience of adjusting the exercise load through the addition or subtraction of the weight disc, but also provides various types of muscle strength. It relates to an all-in-one comprehensive exercise equipment with one arm using electrohydraulic pressure that allows exercise to be performed and thus allows easy muscle training in various areas.

As interest in health grows, the number of people who exercise, especially strength training, or weight training, to strengthen muscles in various areas is increasing.

Meanwhile, during strength training, various types of exercise equipment, for example, rack-type exercise equipment, are used.

At this time, the growth of the muscle can be achieved when the muscle is stimulated and the exercise is slowed while the muscle is fatigued, and the exercise load is increased during muscle exercise so that the muscle can be stimulated more smoothly.

However, in conventional exercise equipment, as disclosed in Korean Patent Publication No. 10-2018-0044556, etc., exercise load was controlled by adding or subtracting weight discs. In order to control exercise load during muscle exercise, weight discs must be added or subtracted. There was a problem that involved the inconvenience of doing so.

To solve this problem, electric exercise equipment has been proposed.

However, conventional electric exercise devices only apply a simple algorithm that accepts information through external sensors and do not take into account information about the reaction force generated by exercise and minute changes in force such as friction force generated by the device itself. There was a problem that it was difficult to respond to the sensitive response of muscles in a fatigued state.

In addition, conventional electric exercise equipment was only able to perform one type of muscle strength exercise, and since it could only train muscles in one area, muscles in other areas could not be trained, so there was a problem in that the exercise effect did not meet expectations.

For the above reasons, in this field, not only is it possible to reduce the inconvenience of adjusting the exercise load by adding or subtracting weight discs during strength training, but also to enable various types of strength exercises to be performed, so that muscle training in various areas can be easily achieved. Attempts are being made to develop exercise equipment that does this, but so far, satisfactory results have not been achieved.
